HandBrake is one of those pieces of software that I've never even had to consider looking around to find something slightly better, it's always done what its supposed to with no fuss. A while back I wanted to rip a DVD my kids got so they could watch it on their tablets and downloading HandBrake was such a no brainer that I entirely forgot that I don't have an optical drive built into any of my computers anymore before installing it.

I love this software. I rip my kids' DVDs using it and play them on a Raspberry Pi with Kodi. This way I don't have to wade through menus, language selection (never defaults to mine), commercials, and ridiculous piracy warnings (I paid for it! Don't treat me like a criminal).

I often wonder if archivists are out there somewhere, armed with HandBrake, ripping every DVD they can find into a digital format for preservation beyond the life of the disc.

I've been fascinated with some projects that have tried to recreate the original theater experience of the original Star Wars,[0] or groups trying to capture classics that influenced Chinese cinema but haven't been widely reproduced, like Red Heroine.[1]

If everything moves to streaming though, even that could become impossible. Wonder how long until they'll stop printing DVDs...

It is amazing to see software that is about 10 years old just hitting 1.0. Never really quite understood that. Is the developer just not confident in it that it is in beta for a while? or is it just a style of versioning? Anyways glad to see development on handbreak.Great software!

HandBrake offers a really nice GUI for many one-off transcoding tasks. If you're looking to automate transcoding tasks with some scripting, handbrake-cli (or ffmpeg directly) are very powerful, albeit overwhelming at times.

For something in the middle - offering both convenience and scriptability - I recommend video_transcoding[1] (uses handbrake-cli and ffmpeg under the covers). It's a really handy set of command-line tools that eliminate a lot of the guesswork and frustration.

I'm a little surprised they aren't signing their MacOS releases. It's even documented on the download page, "We are not currently able to sign the HandBrake downloads". I wonder if it's a philosophical choice or a legal one? It seems like a failure of Apple's Gatekeeper though: either because such a popular app is not able to be signed, or because it's not signed and yet so many people run it anyway.

I'm a huge fan of HandBrake and excited to see them still improving the application. The last time I used a DVD ripper was >5 years ago but it was an essential tool for me earlier in life. I'm happy to see I will still have it available should I need to use it.

I love Handbrake. It's my goto for video transcoding.

I often download stuff for my children from YouTube using a YouTube downloader, and then transcode them to the ideal iPad format, so the children can watch stuff in the car on the iPad without an internet connection. Great for long trips.

Can I just make a general plea?

You should upload your paper to arXiv. When you do, please upload your source (tex, or word I imagine), as well as a PDF.

For the blind, PDF is the worst possible format, and tex and word are the best formats. Don't hide, or lose, the blind-accessible version of your paper.

naftaliharris 1 day ago 3 replies      
This article misses one of the biggest value-adds of arXiv, at least in my field (Statistics): since almost everyone posts to arXiv, you can almost always find a free version of a published and potentially pay-walled paper. In the past, publishing in a peer-reviewed journal would (1) improve the paper through peer review, (2) signal the quality of the paper based on the prestige of the journal, and (3) distribute the paper. With arXiv, publishing now only does (1) and (2).

ArXiv is incredibly useful for research, but I think people also use it for a sort of "I posted it to arXiv first, therefore I solved it first" kind of thing, which imo can be misleading at times, if not everyone follows that. Also there is the eprint.iacr.org which seems to do the same thing, except for cryptography (or is it cryptology?), so I'm not sure if every important preprint in that topic gets to arXiv.

I hope it is replaced with something better soon. You cannot see access statistics concerning the papers you upload, and they provide this absurd reason for not doing it: https://arxiv.org/help/faq/statfaq (it seems they think arxiv users are idiots or something, so they have to take care of us). Also getting the uploaded latex files to be compiled without errors is a pain, and they don't let you to just upload the pdf (this has pros or cons, but I wish there was the freedom to choose... and I guess that 99.999% of the time people just download the pdf).

Carrie Fisher has died theverge.com

RIP. She is, of course, someone special for many of us because of her role in Star Wars.

I guess we need to get used to the rapid loss of famous personalities in the future. Stars are not in short supply because media is good at finding extreme talent and injecting them into our special moments. I remember seeing her on the big screen when I was a kid. I also remember listening to Leonard Cohen with my then-girlfriend and now-wife, or dancing to George Michael songs with friends in my youth. I can think of many great artists, and relate them to special moments. I'll surely miss the ones I'll outlive when the day comes.

60 for Carrie Fisher (or 53 for George Michael, for example) is too young of an age to die. I wish a longer and healthier life for others who make unforgettable moments for us, the audience.

Condolences to her family and to the wider Star Wars community.

On a film-related note: I'm assuming any role she might've had in Episode 8 might've already been shot since the film is in post production, but given that she's passed away and (I figure) Leia almost certainly won't be recast, how might Disney rejigger the storyline going forward? Furious 7 handled Paul Walker's death through CG and the use of Paul's brother to stand in for missing shots, but that was to close out a single film rather than to adjust for broader plot gaps in an overarching series.

Awful news. 60 is young, but as Fisher herself has noted, she's lived a pretty hard life when it came to drugs and alcohol. Her reported weight loss regiment for Star Wars VII couldn't have helped [0]

I understand that the culture of celebrity tickles a primitive part of our brains, and that it's impossible to prevent on a site like reddit. But it bothers me more than it should to see this drivel on a site driven by technophiles.

Why is this death any more significant than any other human being who wasn't lucky enough to be in show business?

Based on the comments and voting, though, I appear to be an extreme outlier in this opinion.

The author draws a hard distinction between Udacity/Coursera MOOCs (good) and traditional master's degrees (bad). I'll interject that with Georgia Tech's Online Master's in Computer Science program [0], which is delivered via Udacity and insanely cheap [1], you can get the best of both! (Their "Computability, Complexity and Algorithms" class is one of the top Udacity courses cited in the article.)

Keep in mind that a traditional degree program does have a huge advantage over a strict MOOC: accountability. It sounds good to say that anybody can go push themselves through one of these courses. Try pushing yourself through ten, and actually writing all the papers and implementing all the code, while working full time and having a family. That grade looming at the end of the semester really does wonders for your motivation. Plus you can get help from live professors and TAs, and the Piazza forums for OMSCS are full of smart, curious students who love talking about the subject at hand. There's a richness to the degree experience that I don't think you get with scattered classes.

(Obvious disclaimer: I'm a current OMSCS student)

The takeaway from this is that those who do best are those with:

- the wealthiest/most financially supportive parents/relatives

- upbringings that are conducive to academic success

- the most free time

as those are the ones who, by a large margin, attend top schools, work at top companies, and have time to spend on self-learning. Another data point of confirmation of a well-studied idea.

Thanks for writing this Aline. As a recruiter for almost 20 years, I wish I had access to all my data and then the time to compile it, and anecdotally I'd expect the finding about MOOCs would be similar.

The most selective of my hiring clients over the years tended to stress intellectual curiosity as a leading criterion and factor in their hiring decisions, as they felt that trait had led to better outcomes (good hires) over the years. MOOCs are still a relatively recent development and new option for the intellectually curious, but it's not much different than asking someone about the books on their reading list.

Unfortunately, demonstrating intellectual curiosity often takes up personal time, so someone with heavy personal time obligations and a non-challenging day job is at a significant disadvantage. One could assume that those who have the time to take MOOCs also have time to study the types of interview questions likely favored by the types of companies represented in this study.

Thanks for continuing to share your data for the benefit of others.

"Whether passing an algorithmic technical phone screen means youre a great engineer is another matter entirely and hopefully the subject of a future post."

This sentence plus the inverse correlation between experience and "interview performance" shown there. Makes a big smell about how biased are those interviews to themselves and not to real technical interviews.

From the data it looks like the questions asked using that service are the ones you might learn in university and after many years not using them, that knowledge fades away because you're not using it.

This is reinforced by MOOCs being the 101 of the subject they're dealing with. It would be interesting to see if there are trivia questions from 101 courses.

The most obvious bias is in the clickbait title. Those 3K interviews are in a specific platform, meaning they're done in a specific way.

So after checking their results it seems that interviews done using that service benefit people with fresh university or 101 lessons knowledge.

What worries me more is the lack of improvement and perhaps the moral superiority of ending the article with a "these findings have done nothing to change interviewing.ios core mission". It feels like the entire statistics game shown there was to feed back what they already knew.

Interesting article! Some minor statistical pet peeves:

1. Setting non-significant bars to 0 seems fishy. Leaving them and putting confidence intervals on everything would let them speak for themselves.

2. Calling something effect size is ambiguous. That's like saying you measured distance in units (and the wiki article on effect size linked makes clear there are a billion measures of effect size).

I'm guessing their measure of effect size were the beta coefficients in a multiple regression?

geebee 9 hours ago 5 replies      
Interesting bit on the MS degree. I followed the link, and I'm not quite as surprised that the correlation is poor, or even negative, given the way the data was collected and analyzed.

Absolutely agree that some MS degrees are pretty much less rigorous cash cows by now, that allow students to skip the fundamentals such as data structures, operating systems, and compilers.

However, many CS MS degrees actually do require this as a background, to the point where some programs have emerged to prepare non-CS majors for MS degrees, kind of like those post-bac premed programs. It's hard to believe that those MS degrees, which require a decent GPA in those core courses, along with high GRE scores (sorry, but we are talking about interviewing skill, which may be more related to exam taking ability than job performance), wouldn't result in a similar profile to people with CS degrees from top schools.

This is fully acknowledged in the text of the article referenced in a link, but unless people follow it, I do think the message may be a bit misleading.

That's an aside, though. The value may very well be in the prep for these degrees (ie., the post-bac CS coursework required for admissions to a reputable MS program). If you can get that through online courses (udacity or coursera) through genuinely rigorous self-study? Yeah, that might do it, for far less money. I've audited a few of them, and they're the real deal, that's the real coursework there.

Not to harp on the "technical interviews are disconnected from actual work!" angle too much, but I'm reminded of a comment from a thread about the creator of Homebrew failing a Google interview.

I wonder if that's a disconcerting fact for some employers to grapple with.

This is a very poorly done analysis. At a minimum she needs to define top school/top company. Also I'd like to see the confidence intervals around the effect sizes. In addition, looking up MOOC information from LinkedIn may result in a lot of false negatives. (She doesn't mention if MOOC courses in non-CS subjects count.) Did all the interviewees have CS degrees? What about the Masters degrees, is she including non-CS ones? Is the sample of interviewees representative or there's any selection bias that we should be aware of?

A study which doesn't answer so many basic methodological questions is garbage.

Searched the article and the comments here for "Pluralsight", with zero hits. So what makes Udacity/Coursea preferable? TLDR, I'm asking this as Pluralsight was a significant contributor to my landing my latest role after redundancies.

The long version: I recently landed a role after some time off, having changed from mainly back end Php/Coldfusion to C# in the last year. I was able to make the switch in my last role. For me, moving to C# was a big transition; as well as guidance from a (fantastic) mentor, I used Pluralsight to learn C#, asp.net and DDD - e.g. from Jon Skeet, Scott Allen and Julie Lerman, to mention but a few.

Being completely burnt-out on the old stacks, I was set on making my next role a C# one. I've come to love what Microsoft are doing with Core, open sourcing etc, as well as the strictly typed C# language and ability to use NCrunch with live unit tests. So I signed up for a year after relinquishing my corp subscription, kept doing their courses, and found the training material highly accessible with great quality content. Each interview was a learning process, when I didn't know something from a test, I'd go and study it so that I'd be better prepared for the next role. One of these was the study of data structures and basic computer algorithms, where I was lacking. I might not have had years of experience, but the experience I had was mostly best practice.

During my search, I typically got great feedback on the fact that I was doing Pluralsight courses, and it was a significant factor in being hired for the new role - it showed cultural fit, in addition to passing their tech tests (which happened to involve structures). My company had interviewed a lot of candidates, struggling to find the right talent. Just possessing technical skills is one thing, having the right attitude towards learning is another.

At any rate, I'll keep using Pluralsight to raise my proficiency in my new stack - even as an old timer, I am having a newfound level of enthusiasm towards my whole profession which I haven't felt since I coded in assembly on the good old Amigas. I would be interested in knowing why Coursera / Udacity might be better or more accepted in the marketplace though.

I wonder if "took courses" could be a stand in for "prepared heavily". It seems like people with all the other attributes might think they didn't need to study. People without them might think they did and took courses to "catch up". In my experience, preparation is the key driver of performance in these types of interviews.

It seems reasonable that a person who took a MOOC might have prepared in other ways as well while people who didn't probably didn't prepare much at all (since watching a few Algo lectures seems the most accessible refresher.)

Interesting and surprising, especially the experience thing. I think I am a significantly better engineer than earlier in my career, so I assumed experience would count for a fair bit. Then again I have inherited projects from experienced guys who make crap high level architecture decisions and the code is way more difficult to work with than it ought to be.

But then this article seems to be measuring interview performance, not actual ability on the job. So is any of it actually relevant at all?

Until recently I worked at a startup as Machine Learning Engineer/Data Scientist. There I got some experience interviewing people and looking at their resumes. In my experience, which is very limited compared to this post, people who put an MOOC on their resume are usually less qualified compared to people who don't.

There is nothing wrong with MOOCs, but they are almost always beginner-level. If you put them on your resume it kindof implies you don't have a lot of experience beyond that. Putting the Coursera Machine Learning course on your resume would be the equivalent of putting Java 101 on your resume for a Software Engineer.

I would recommend anyone to put projects on your CV instead. Even if you don't have a lot of work experience, just put side-projects and school projects on there.

The master's in CS can be useful if:

1. You have an undergrad degree in liberal arts2. You pay as little tuition as possible3. You take no time off and continue to work FT

These apply to me -- my undergrad was in English, I paid 6k total (27% of the 21k total cost) and went to school at night over 4 years while my career continued to progress.

Most of the people in my program couldn't write a FOR loop if their life depended on it, they viewed it (incorrectly) as a jobs program while the school needed the $$ to keep the dept afloat, so I'm not surprised they fared poorly in technical interviews.

But that doesn't mean the degree isn't useful. If you're already a programmer, it helps get your foot in the door at many places. HR managers/recruiters feel more confident forwarding on your rsum, they can't parse your GitHub repos.

The degree is icing on the cake, it's not going to magically turn you into the Cinderella of Programming if you have no real-world experience. I got my master's with a QA and a paralegal and today? They're still a QA and a paralegal.

That being said, timed technical interviews are almost universally asinine, IMHO. When in real life do you have 10 minutes to figure out a problem? Or are prevented from Googling the answer? The measure of successful programmers is how efficient and professional they are in problem solving, not how much useless information they can keep in their head.

Things I've never had to do in 'real' life:-Never had to split a linked list given a pivot value-Never had to reverse a string or a red/black tree-Never written my own implementation for Breadth First Search

etc etc

Personally I'd rather see take-home assignments that roughly approximate the type of work you'd do, which in my career has been churning out new features or applications. Does knowing the time-complexity of radix sort vs heap sort really have a material impact on your effectiveness as a programmer? No.

Unless I missed it in the article the data is all about passing the interview not acutally seeing if any of these things correlate to the employees working out in the 1,3,5 year time spans.

With this data you're just biasing towards people who interview well, which, I don't think you actually care about.

Well I mean I guess you do if you're a recruiter (if you're a moral recuiter you care about both), but not really if you're an employer.

yes, this is absolutely startling:

For people who attended top schools, completing Udacity or Coursera courses didnt appear to matter. (...) Moreover, interviewees who attended top schools performed significantly worse than interviewees who had not attended top schools but HAD taken a Udacity or Coursera course.

Possible explanation might be that people going through regular degree typically spread themselves thin over many subjects (digital electronics, compiler design, OS theory, networking etc) while MOOC folks sharply focuses on exactly the things for interviews (i.e. popular algorithms). Its like interval training for one specific purpose vs long regime for fully rounded health. The problem here is not academic system but how we measure performance in interviews. I highly doubt if results would be same if interviewers started asking questions from all these different subjects instead of just cute algorithm puzzles.

Interviewing is a funny thing.

I remember when I graduated from a "Top School" and interviewed at "hot startups" from the valley. I aced a lot of the interviews - why? Because I had just taken classes on LinkedLists, Binary Trees, HashMaps, etc... So when they asked me to whiteboard a "shortest path algorithm" it was just rehashing what I did in school.

Years later, looking back, I fail to see the relevance in most of the technical questions. In fact, if I had to do those questions over again today I would probably fail miserably. Yet, I have been in the industry for a while now and have worked with countless more technologies and have accomplished far more than my younger self.

Just because someone performs well in a technical interview doesn't mean they will do a good job. That is the data that really matters. I've interviewed hundreds of candidates as a hiring manager for some big startups, and from my experience technical interviews are not a great indicator of success.

I'm saying this coming from someone who has gone to a "Top School" and done multiple Coursera/Udacity/etc classes.

Yes, someone might be able to whiteboard a random forest or write a merge sort, but do they know how to engineer a system? Can the candidate:

> Communicate well with others in a group?

> Solve unique technical problems?

> Research and learn new technologies effectively?

> Understand how to push back to product owners if there's scope creep?


These are all things that are not really analyzed in many technical interviews.

As I'm reading this analysis all I can think of is that it is pretty useless - if not dangerous for the industry.

What I've found is that it is critically important that someone knows how to code at some basic level. But their ability to code and explain algorithms on the fly, while probably relevant in academia/research, is such a minor part of the day-to-day of a programmer - At least from my experience.

Sad to see so much detail paid to the data, and so little to the setup of the experiment itself.

It shouldn't be surprising that an online technical screen favors candidates who've participated in a MOOC, but is blind, say, to years of experience. A screen like this is timed-performance-at-a-distance, which resembles MOOC participation. The full spectrum of qualities that comprise a Good Hire might incorporate the other signals from the post, but this type of interview won't test them.

(I'll be the first to admit I'm biased against performative coding in engineering interviews. Tech screens like this are often necessary, though, so they have their place.)

ditonal 9 hours ago 4 replies      
Very unsurprising for me. You are measuring your ability to solve algorithm puzzles. Most engineers don't actually do many algorithm puzzles in day-to-day work, especially the types of algorithms that interviews tend to focus on like sorting and dynamic programming. So "years of experience" is not measuring experience in what you're actually being tested on. On the other hand, you do exactly those types of things in many CS classes, and in Coursera classes, algorithms are exactly what you practice. So it makes sense it correlates.

Top company is a predictor for the obvious reason - it's selection bias for people who already passed those interviews at the company. You're not good at the interview because you worked at the company, you work for the company because you're good at the interview.

Master's degrees seem like largely for international students needing visas, career switchers, etc so not surprised they are not a strong predictor. And if anything the course material moves past the intro data structures stuff the whiteboard interviews tend to test.

The only huge surprise for me here is that Coursera is a stronger predictor than top company and top school. I would have predicted top company > top school > Coursera.

The post that I would be much more interested in is correlating performance reviews to interview performance. That gets suggested as a possible future post.

Interview for job: a. cram for interview by going to coursera to crunch memory according to interview memes based on the whims of the interviewer. b. spend the rest of term of employment exercising skills which tend to be tangentially brushed upon during both interview and schooling while the majority of actual tasks are often googled and stack-overflowed into place based on arbitrary design decisions and politicized stack choices. 3. Results: a. good interviewees have learned appropriate memes to reassure interviewers. b. good students have learned obligatory cruft to reassure professors. c. actual necessities are tangential to many or most entry barriers.

I've noticed that Switzerland, using a lot of hydropower, has a worse intensity than I expected.

The CO2 numbers for the different types of power generation seem to come from Wikipedia [1], where Hydropower has a median gCO2eq/kWh of 24 and a maximum of 2200 much worse than coal. This seems to be based on the fact that large areas may be flooded when filling the dam initially, and CO2 from rotting plants is released [2]. The numbers vary depending on the amount of vegetation.

According to a study [3] from 2012, "electricity generated in storage hydropower stations in Switzerland causes emissions of 10.8 g CO2-eq/kWh", so it's less than shown in the emissions chart and comparable to nuclear.

In Sweden one uses 8000kwh of electricity per year. 58g/kwh = 464000grams, 464kg co2.

Average car co2 emissions around 120g/km. Average distance driven here around 15000km. 12015000=1800000grams 1800kg.


Co2 emissions of meat 13300g/kg, average meat consumtion 80kg.8013300=1064000grams 1060kg of co2 from meat.

adding the above. 464kg+1800kg+1060=3324kg, still missing some to add up to per capita consumption. What co2 source is missing?

This is a very pretty map! It shows that location is important but time is also an interesting domain. You can do your bit by running appliances at the best time. This is a post I made on https://energyuse.eu (part of an EU trial I'm involved with - https://www.decarbonet.eu).

Saving energy in general is a positive step. For example, we've just bought a new freezer and dishwasher with better energy ratings and these will save money over their lifetimes. However, when is the best time to run a wash to save the most CO2e?

Unless you are on an Economy 7 style tariff or have solar panels then when you use power has no effect on how much it costs you. If you are, then at night or in the middle of the day is better, respectively. Dynamic demand to grid signals isn't ready for consumer adoption yet but you can look at the information manually if you want to use power at less demanding times.

The grid frequency[0] is a reasonable indicator but is pretty technical. There are other, easier to understand, data sources available:

- Earth Notes: GB Grid Intensity[1] gives a simple traffic light indication

- GridCarbon[2] is a real-time carbon intensity app (CO2 Modeller[3] is from the same guys)

- MyGridGB[4] shows similar data on the web (and includes Solar data[5])

By avoiding peak time you may not save money but you can save carbon.

"Early in 2016, under American prodding, the Iraqis reopened negotiations with Trevi S.p.A., the Italian firm. In September, a team of engineers, hired at a cost of three hundred million dollars, arrived at the dam to perform a crash repair job. Their main task is to install updated equipment, designed to fill the voids beneath the dam more precisely, and to repair the broken control gate. Under the contract, the Italians will do the grouting for a year, and then leave the equipment with their Iraqi counterparts. The engineers say that they are confident they can prevent the dams foundation from washing away."

We feel our way through, Jabouri said, standing by the pump. Generally, smaller cavities require thinner grout, so Jabouri started with a milky solution and increased its thickness as the void took more. Finally, after several hours, he stopped; his intuition, aided by the pressure gauges, told him that the cavity was full.

The irony saddens me that, if you replaced that worker and his human lifetime of knowledge with a "data-driven control system" and his intuition with a "machine learning algorithm", we would all hail the result as the pinnacle of technology in mainantence systems - even though the data and actual descision making would be almost the same...

A quick calculation of what it would take to replace the dam with solar panels:

According to wikipedia the dam produces 1052MW. Let's call it 1GW. https://en.wikipedia.org/wiki/Mosul_Dam

According to quora you need about 10000m2 or one 1ha to produce 1MW. So 1000 * 10000m2 = 10km2 to produce 1GW.

I wonder how big the lake is? Could solar panels installed in the drained lake - theoretically - provide the same or more energy than the dam?

Of course energy storage is a major part of water power and it is not taken into account above.On the other hand a decentralized power grid is one of the major advantages of solar (especially in an unstable country) and that is not taken into account either.

A bigger problem than both: the 100-1000x atmospheric mass in methane calthrates bubbling up from the ESAS that have the potential to push climate change beyond +6 . Get ready for high food prices, more failed states (and more mob armed cults), regional WMD wars and mass exoduses.

It sounds rhetorical and impossible at first glance if the evidence including satellite measurements and field observations weren't so definitive. Preppers don't sound so insane at first but they're probably not thinking about sustainable semi/off-grid living in a radically-altered climate.

I think this "machine learning for hackers" approach is just not enough. Oftentimes, you do need a solid theoretical/mathematical background. Most people seems to approach ML like they approach programming tools or libraries - learn just enough to get job done and move on.

I was studying machine learning from Andrew Ng's CS229 (the class videos are online. I think they date from 2008 or hereabout). There is no way you can progress beyond lecture 2 (out of 20) without a solid probability background. A solid background in probability/statistics probably means a good first course in Probability or maybe the first five chapters of "Statistical Inference" by Cassias and Berger. Similarly, for SVM, you need a solid background in Linear Algebra and so on. You probably also need a background Linear Optimization. Here are the recommendations by Prof. Michael Jordan https://news.ycombinator.com/item?id=1055389

Not a lot of people want to dive in this much. They have got things to do and who cares about proofs anyway. The thinking goes like "Most of the mathematics is abstracted away by libraries like scikit-learn. Let's get shit done.". Well, I think a lot of competitive advantage of Google/Facebook in ML is because they have staffed their engineering with people who have studied these things for years (by PhD). Compare that to flipkart's recommendations.

However, I don't think this problem is unique to ML/Data Science. It is equally bad in "Distributed systems". Let's use Docker, that's the future!

> So I am doubling down on ML/DL.

The amount of free resources now available for learning machine learning/deep learning nowadays is robust and easy to comprehend. (indeed, Andrew Ng's Coursera class is very good). And running running ML code is even easier, with libraries like Tensorflow/Theano to abstract the ML gruntwork (and Keras to abstract the abstraction!)

I suspect that there may be machine learning knowledge crash, where the basics are repeated endlessly, but there is less unique, real world application of the knowledge learned. I've seen many Internet testimonials saying how "I followed an online tutorial and now I can classify handwritten digits, AI is the future!" The meme that Kaggle competitions are a metric of practical ML skill encourages budding ML enthusiasts to look at minimizing log-loss or maximizing accuracy without considering time/cost tradeoffs, which doesn't reflect real-world constraints.

Unfortunately, many successful real world applications of ML/DL are the ones not being instructed in tutorials as they are trade secrets (this is the case with "big data" literature, to my frustration). OpenAI is a good step toward transparency in the field, but that won't stop the ML-trivializing "this program can play Pong, AI is the future!" thought pieces (https://news.ycombinator.com/item?id=13256962).

Distributed Systems and ML are probably two most interesting things that I have on the radar, that got me really scared to the point where I do not know from where to start, and most importantly for what?! Most of my free time (time I spent on personal projects) was writing physics simulation in Java, playing with Lisp and doing some backend development. Nothing amazing. Year and a half ago I got really interested into Operating systems (tried FreeBSD and blew my mind) and played with Docker. And at the end of this year, I am like:"Ok Philip what shall I focus on for year to come?" And the thing is If I choose to go Ai route, I do not know from where to start (I consider my math background to be pretty good, I was studying EE before I dropped out after 2 years, and enrolled to CS, done all of the math courses which were pretty rough), Ai/ML looks interesting but it looks so high level to program and so abstract to understand. It's really looking like arcane magic to me. With Dist. Systems is that I have a feeling that is more "engineering" and "industrial" thing, where you can't do much by yourself at home, besides reading and writing some code in relevant languages about backend, sometimes lower level, and learning about systems and computer innards. And the third option was to go and play with Erlang/Elixir, which is most attractive since results will come pretty soon, and may be relevant form my interest in Distributed systems.

I have an almost opposite problem. I spent years learning alot of ML stuff and worked at a job doing this kind of work for a couple years or so. I think the issue was that the data we had at the organization and the internal politics seemed to make it difficult to use for ML in a way that mattered to the business. I grew frustrated with having spent alot of time learning things that were exciting then realizing it didn't really matter if some manager can just say "we're doing it this other way that makes sense to me." (Not based on data, but gut feelings)

I'm not sure what to do with that. Probably ML works best in organizations and situations that are on board for using ML to make decisions for the business. Here's the other thing -- finding a business where ML is core to its decision making that will hire a person with no formal ML related education may be difficult. Perhaps I'm wrong about that and have just given up on ML after my frustrating experience.

Now I'm building data systems that the business uses on a daily basis to get things done. I feel alot better doing that than ML stuff, even though I loved playing with data and ML. I guess I've given up on ML for now, maybe I'll find my way back to it again.

The result you get with this trick is signed, while the result you get with sizeof is unsigned.

Edit: Just to clarify, what you get is ptrdiff_t instead of size_t. So if array size is greater than PTRDIFF_MAX, you get undefined behavior [1].

Stratoscope 2 days ago 6 replies      
Whether you use this method of getting the number of elements in an array or the more traditional sizeof method, please encapsulate the logic in a macro.

Instead of writing either of these:

 size_t length = sizeof array / sizeof array[0]; size_t length = (&array)[1] - array;
Define this macro instead:

 #define countof( array ) ( sizeof(array) / sizeof((array)[0]) )
Or if you must:

 #define countof( array ) ( (&(array))[1] - (array) )
And then you can just say:

 size_t length = countof(array);
Edit: I used to call this macro 'elementsof', but it seems that 'countof' is a more common name for it and is a bit more clear too - so I'm going to run with that name in the future.

For the completeness sake, the size of an array can also be computed via linker symbols, see for example: http://stackoverflow.com/questions/29901788/finding-the-last....

Same constraints apply (pointer arith).

I am not sure why this method, applied to ordinary arrays, would be preferred to sizeof (), but since we're shedding light here...

EDIT: pointer arith constraints only apply if we compute the difference (end - beg) in the C code. We could also do that in the linker script itself, and I don't recall whether or not C semantics of ptrdiff_t would be preserved in that case. Such preservation doesn't seem very probable to me, so potentially this method might allow to avoid overflows (or to move them much higher) -- to be checked in the 'ld' doc!

While this is as interesting as any c arcana, I truly hope that people are not passing around pointers to arrays and then using sizeof(array)/sizeof(elem) to figure out how big they are, like they are stuck in a first year programming assignment that denies them the use of malloc, so they use C99 VLAs everywhere.

this is undefined behavior. &arr + 1 can overflow. There's no guarantee &arr isn't near memory end boundary. &arr + 1 is converted at compile time to rbp - X where X is an integer determined by the compiler similarly to how sizeof works.

Basically ptr + integer requires the compiler to determine the sizeof ptr's type.

I haven't written C in a while, but I think this is pretty stupid. sizeof() is a compile-time thing in C, so it's substituted with a number by the time you get an executable. See:


I think this is effectively doing the same thing, but in a non-standard way; ie. I think `int n = (&arr)[1] - arr;` is substituted with the actual the number by the compiler the same way sizeof() would be, only noone will know wtf is going on.

Disclaimer: I didn't look at the generated code to confirm; I guess it could even be compiler/runtime dependent.

FreeDOS saved my bacon some years ago. I was working at a college and one day a chemistry prof came in and said their spectrometer (IIRC) was dying. I took a look and found an old 386-based machine with a hard drive on the fritz. It ran some odd version of DOS from a company that no longer existed, there was no budget for a replacement, and classes relying on it were starting soon.

My memory is hazy but I was able to get a compactflash card with FreeDOS on it and used it to boot the system. The special programs that operated the device over the serial or parallel port took a little work to keep from crashing, but eventually all was working as before.

DOS + Win 3.11 was very fast compared to Windows (9x, XP, 7 and 10), OSX or Linux nowadays and there were lots of good games written for the platform (MOO1, CIV1, Duke Nukem 3D).

I read about the problems with Windows 3.11 protected mode, does FreeDOS 1.2 allow you to run Windows 3.11 in 386enh and protected mode?A certain Jeremy David wrote support for it, and I read that a windows 3 compatible kernel was available in FreeDOS 1.0 under the name Winkernel. It should be used without EMM386 but with Japheth's versions of HIMEMX and SHARE, allocating at most 256 MB of RAM to HIMEMEX. With some tweaking of the Windows config, it is possible to use 1 GB, but not more. Do not use protected mode disk drivers.There is SVGAPatch: a tool to patch svga256.drv to make it VESA compliant so Win 3.11 can be used within Virtualbox. http://web.archive.org/web/20140202233045/http://www.japheth...http://stephan.win31.de/w31mm_en.htmhttps://www.kirsle.net/blog/entry/nostalgia-for-windows-3-1

I remember that for DOS semi-multitasking you could use DESQview, does that work with FreeDOS and are there better (more efficient or open source) alternatives?

I am asking as you could make a very lean and fast OS, booting form USB, extracting itself to a ramdisk, allocating 500M (with tools, editors and games) and 500M for windows.

Perhaps HaikuOS, NT 3.51, Windows ME with KernelEx or the new OS/2 5 (ArcaOS), or Win7PE or Win10PE are more capable and similarly faster compared to Ubuntu, Windows7/10 or OSX.https://www.arcanoae.com/current-release-timetable-arcaos-5-...http://theoven.org/index.php?PHPSESSID=4883b8169b752f637e361...

If anyone is interested in doing TCP/IP networking on DOS (and it may work on FreeDOS [1]), read on:

Reading this thread, I just remembered that I used to have an old IBM PC Jr that ran DOS (years earlier), a great machine hardware-wise (though it was not a marketing success, I've read). And some time back I had written this post about it:

Lissajous hippo, retrocomputing and the IBM PC Jr.:


While looking up info about the PC Jr. for that post, I came across Mike Brutman's PC Jr. page (mentioned in my blog post):


He was an IBM employee for a long time and so had access to good info about the PC Jr. - both hardware and software, and his page above is one he maintains about that machine - a sort of retrocomputing site about the Jr.

We then talked some on email, and he told me he had built a TCP stack for DOS and was running it on his Jr. That page is here:


He says others are also using mTCP, for fun, work and even business.

Here's an excerpt from his overview section about mTCP:


[ mTCP should run on all variants of DOS including IBM PC-DOS, Microsoft MS-DOS, DR-DOS and FreeDOS. All of these applications will run well on the oldest, slowest PC that you can find - I routinely use them on an IBM PCjr made in 1983 because nothing beats the fun of putting a 30+ year old computer on the Internet.

People are using mTCP for goofing off and for real work. If you have a DOS machine that needs to send data across the network mTCP can help you get that done. Besides its utility to vintage computers I have heard of people using it to transfer lab data from dedicated industrial PCs, allowing backups to be run on old machines, and sending sales reports from the branch offices of a retail store to a central server.

Don't have a vintage computer laying around? No problem! mTCP applications will run in a variety of virtual and emulated environments. It has been tested with DOSBox, SwsVpkt, VirtualBox and VMWare. See the documentation for the details. ]

I thought CyanogenOS was a commercial venture that arose out of CyanogenMod. But that they were essentially separate protects. I'd read about CyanogenOS coming a cropper, but understood this wouldn't affect CyanogenMod. Now, these linked articles seem to be treating -OS and -Mod as the same project/same organisation.

Can anyone explain?

A couple thoughts:

Unless your image library is way fancier than I imagine, you would get a much less biased result if you convert to a linear color space. This code:

 # Invert grayscale image def invertImage(image): return (255-image)
doesn't accurately compute amount of thread cover desired because "image" isn't linear in brightness.

For this particular use case, though, you probably want to further transform the output. Suppose that one thread locally reduces light transmission by a factor of k. Then two reduce by k^2 (assuming there's enough blurring, everything is purely backlit, no reflections etc), and so on. So n reduces the log of the brightness by n*log(k). I would try calculating -log(luminosity) and fitting threads to that.

Finally, this sounds like a wonderful application of compressed sensing. I bet you could get an asymptotically fast algorithm that is reasonably close to optimal.

Very cool! How much is it affected by the method of new pin selection after each time we add a line? I.e. currently you are doing oldPin = bestPin, and the first pin is selected at random... wouldn't it be better to just add lines based on a Hough transform (with rounding to the nearest pins) - starting from the line which covers the maximum number of points, and going down?

One of the main causes of accidents are vehicles left on the road and other vehicles impacting them or the people as they take for granted that traffic will be fluid and are distracted or whatever.

You should never leave your children and family on a car on the left lane while you leave, never.

I have a neighbor that is paraplegic because of that. His entire family went to the hospital after a vehicle crashed from behind after a minor accident.

Your first priority is putting your car and family on a safe place. Proper triage priority number one is avoid another accident, by removing obstacles and signaling other cars.

This is great video to study on many levels beyond self-driving car. Some observations:

* The car behind didn't show turn signal so probably driver wasn't paying attention.

* A small car escaping with not too much damage while SUV rolls over many times

* From physics point of view, the car behind produced almost perfect torque that started horizontal spin on SUV

* Collisions with barrier at high speed can produce lots of rolls. Many time we see cars upside down in accident and wonder how did that happened. This is how.

* The middle barrier did its job wonderfully even against massive inertia of SUV. Cars on other side remained unscathed!

I think this accident could've been entirely avoided had the small pink hatchback been a Tesla.

My read on what happened here is that the pink car was making a passing maneuver, and just as the pink car driver checked their right-side mirror/blind-spot and hit the right turn signal to get out of the passing lane, the car ahead abruptly stopped. That explains why the pink car drifted so slowly to the right - it wasn't an avoidance maneuver, it was a simple lane change while unaware of the stopped car ahead. Presumably an autopilot in the pink car would've been able to see the stopped traffic ahead and hit the brakes even while the driver was looking to the right to change lanes.

Here is a video by Bjrn Nyland demonstrating the ability of the Tesla radar to detect the motion of the car in front of the car you are following: https://www.youtube.com/watch?v=cG3Jp5GyPoc

It shows, how the radar detects, that the lead car breaks first - watch how it gets highlighted in the dashboard. This ability helped the Tesla to handle this accident event.

samch 10 hours ago 0 replies      
Just brilliant technology at play there. I had to rewatch a couple of times to really grasp how early the Tesla recognized the emergency braking scenario.

One thing to note is that most dash cams, mine included, shoot at a fairly wide angle. The Tesla was likely following a good bit closer than it appears from the video alone.

This is also an interesting visual demonstration of why that Armco barrier between the opposing directions of traffic is so terrific. It's quite possible that having that in place saved several lives in this accident. It clearly absorbed some of the impact energy and prevented the SUV from crossing into oncoming traffic.

I'm sorry but is everyone here sucked into the "reality-distortion field" that Tesla Auto Pilot seems to be generating? Nothing happens in this video that a competent driver wouldn't have done.

Detailed Explanation:In the UK part of the driving theory test is a "Hazard Perception"[1] exercise that test candidates awareness of hazards around them by playing short video clips and getting the candidates to click when they first spot a hazard they would need to respond to.

When watching the linked video I 'click' at 0:04 when I see the multiple brake lights though the car directly in-front. This coincidentally is when the Tesla responds with its audible warning.

The factors that lead to the Tesla not being involved in an accident in this video were not related to Auto Pilot but due to a competent driver: 1) Maintaining appropriate breaking distance from the car ahead to i. be able to stop in-time but without being tail-ended due to fast breaking ii. have 'thinking distance' to allow for slowed reaction timing 2) Watching the road ahead and noticing solid breaking of ahead vehicles though the directly in-front vehicle. There is NO AUTO PILOT MAGIC IN THIS VIDEO

I do not dispute that in other circumstances and perhaps other videos Tesla Auto Pilot HAS prevented and accident that a human would not have. This video is NOT such an example.

It's nice to know that Tesla can do that, but sorry, I just don't see anything "magical" in this video -- speed wasn't that high (~110 km/h), the gap was quite wide and the two cars on the right lane also managed to pull over and stop in time too. I have personally avoided much closer encounters driving both car and a motorcycle. In such situations, you should pray that there's no truck behind you.

Also, I think the driver deserves some credit. Note how he keeps calm and rational and tells the other adult occupant in the car to not rush out into the road and cause another accident. His first thought is to make sure he understands what is going on behind him. Cool head, good job.

This is the bit driving schools rarely (if ever?) teach and which many drivers never get a chance to think about until they find themselves in a stressful situation where they can end up making dangerous decisions. (And then, of course, most people do not think).

Road and Track says no.[1] "Except, if you watch the video, you can clearly see cars stopping ahead of the driver who isn't paying attention starting at the two second mark." What you're seeing here is that radars are much better at range rate than vision. Range rate data from a radar is as good at long range as it is at short range.

Fortunately, they were right behind the accident. If the wreckage was stopped and partially blocking the left lane, Tesla's autopilot probably would have plowed into it. Like this fatal crash in China[2] and this non-fatal crash in Germany.[3]

We don't need to speculate as to the speed or proximity of the two vehicles ahead. The data the autopilot system used has it. Does Tesla own that data, or the vehicle-owner? It's collected on the vehicle, which is _owned_. I'm sure Tesla gets a copy -- do they retain the rights as well?

I would not be surprised if Tesla were subpoenaed (or otherwise requested of) for the data, in a case like this (similar to the recent Amazon Echo news, or cellular providers with geolocation in abduction cases).

I think the most exciting thing (and we're way behind schedule on this, a lot of this could have easily been done literally 30 years ago, no problem at all), is caravan functionality, where a group of cars moves together. If you imagine 20 cars at a standstill for some reason, if they begin to move forward slowly but at the same time (less than 50 millisecond apart) because they're coordinated then they can get up to speed almost as fast as if it were only just one car (let's say they have to speed up a bit more slowly for a safety allowance). But if you factor in human response time, it can be a phantom traffic jam. There is no reason for a traffic jam because there is clear road all the way ahead of the group - yet a traffic jam slowly makes its way back anyway. Like this: https://www.youtube.com/watch?v=goVjVVaLe10&t=1m55s

coordinating this stuff doesn't require computer vision or truly self-driving cars or anything like it and could have been done 30 years ago (1986) over an AM radio standard and some kind of coordination between cars - just nobody sat down and designed that standard.

today wireless coordination technology offers dozens of choices (in the gigahertz domain) and caravans could be assembled all but "trivially", cars can know where they are via gps with no problems at all. That would be an exciting move forward. Of course, it only works when everyone is doing it, but if just a few traffic jams instantly disappear (the ones where are the cars happen to have caravan functionality and coordinate) it would improve things for everyone: the traffic jam will disappear whenever it bunches up in a way that happens to consist of coordinated cars. (e.g. a 3-car phantom jam slowly moving backward will disappear whenever it crosses 3 caravan-enabled cars - not every car has to have this functionality). But I haven't read anything about Tesla coordinating even with other Teslas, let alone some standard of intercar coordination. A shame - this stuff is way easier than the self-driving stuff Tesla and others are doing. It's very low-hanging fruit.

Don't be deceived: the reason why these plans look nice is because of the team structure of the Zelda project. The design team spent a lot of time drawing up polished graphics and layouts and then "threw it over the fence" for implementation, in waterfall fashion. This is still a common practice within Japanese teams, as evidenced by, for example, Mighty No. 9's documentary, where you can witness an entire level constructed in Microsoft Excel. [0] The separation of roles is not a definite downside if the game design is already well-understood, and American teams have flirted with big up-front design on occasion, but tend to lean towards making sure everyone stays hands-on and can test and iterate independently.

One of the stories about Zelda that appears in interviews is that the second quest is the result of a miscommunication about how much space was available: They could have had a single quest that was twice as big.

The main direct advantage of drawing everything out is that you can quickly explore different types of setups(relative scales, positioning, iconography, etc.) and do a few passes of testing on it before committing it to code, for the same reasons that one might do wireframing and mockups for application UI.

The device doesn't start listening when you say the wake word, the device is always listening. It's only the UX that responds when the presence of the wake word is detected. This means that the device is continuously monitoring the environment for the presence of the wake word we know about ("Alexa").

Can the device monitor for other words that trigger other UX sequences? Of course it can!

Can Amazon deliver an OTA update to this network connected device to change behavior after it leaves the factory? There is no reason to believe that they cannot.

So, no, I don't believe the police are wrong here. In fact, I would be in favor of law enforcement having the ability to "tap" these network-attached microphone appliances with a warrant. Then, perhaps, people will begin to understand what they've really bought.

EDIT: Passive monitoring ("listening") is not the same thing as storage ("recording"). In some cases below, these are being conflated.

Alexa listens only to the words after the wake word. What's more it doesn't capture more than 10-12s past the wake word. If you have a device you can check this yourself (Alexa, One Mississippi, Two Mississippi).

It's actually hard to get it to capture this much. Take a breath or pause to long and capture stops sooner.

The request of the police is nutty and indicative of not understanding the technology. Unless the murdered woman yelled out "Alexa {pause a little bit for wakeword recognition} Heeelp, my husband is killing me, call the police" or the husband asked "Alexa, how do I clean a bloody hottub", nothing material will be discovered.

I have 4 of them. After the first one I checked what was captured, what was stored, what was streamed. Nothing that mattered.

The part that listens for the "Alexa" word is analog not digital.

It cannot be updated remotely by firmware.

Crack open the device, test the analog component and confirm the signal only fires when you speak alexa and nothing else.

Check what they did with Cisco equipment sold to foreigners. They intercepted the shipment, tempered with the device and no one was any wiser until the Snowden leaks. Cisco now ships via proxy to guarantee no tempering.

Also interesting that the lawyer is going for the reasonable expectation of privacy regarding that data, if that holds, then it could allow them to argue due protections from the 4th amendment.

But let's ask the question here; is data regarding usage of utilities private? It seems that something that you installed for water usage, should be. Could this data not have been acquired from the water department?

This brings up an interesting question. If I say "Alexa, call the police!" or "Alexa, I need an ambulance!" will anything happen? It doesn't officially say it can be used to request emergency response and I'm scared to try it.

I wonder if they've received a lot of these requests and/or if they have an emergency team on standby.

Late to the game here and apologize if this has already been mentioned but may shed some light on what is actually stored. A while back facebook officially announced what they "store" in regards to what they record when the app is open and has access to your microphone. The app itself turns your voice audio into a profile that is then sent to the server, it does not send your actual audio. This light(er) weight audio profile is then matched to words which are then used for marketing. I wouldn't be surprised if Echo, Google Home, etc do something similar since sending the full audio recordings would be both bandwidth and storage heavy.

I see that a lot of people say that police did that because it is incompetent. But what if this is actually a way for police and other low tier agencies to check how much Amazon collects? I bet NSA would never work with police and most likely not much with FBI etc. So this might be just a check? This is just a speculation, but we should not assume stupidity of some of the agencies just because its an easy answer.

Is there a technical reason for storing this after NLP processing has been completed on the "utterance."? Wouldn't an ephemeral cache be sufficient?

I'm the guy that made Agar.io, Diep.io and a few smaller games. I analyzed the possibility of using WebRTC in my games several times so far, but it seems that right now, it's still hard to use in a server-client architecture. You need to bring this [1] behemoth and all of its dependencies to your project dependencies on the server side, even though you only care about a tiny bit of it (unreliable data channels). It's unlikely that people will start using it until there is an easy stripped-down version that only deals with data channels.

We've been using WebRTC Datachannels for multiplayer gaming in the browser in our game editor Construct 2 (www.scirra.com) for a couple of years now. Generally they work great! However the main problem we have is switching tab suspends the game, which if you're acting as the host, freezes the game for everybody. This is really inconvenient. There ought to be some way to exempt tabs with WebRTC connections from being suspended. I filed a bug for it here: https://bugs.chromium.org/p/chromium/issues/detail?id=676036

When I started development WebRTC wasn't very well supported, now I am considering using a hybrid. I already use two websockets, one for binary state snapshots and the other for JSON important updates like entity creation and chat. It would be interesting to implement WebRTC to my servers just for the state snapshots.

ndesaulniers 1 day ago 0 replies      
Not until server-side implementations exist. Depending on the physical location and amount of data being replicated, you'll need the flexibility to move master-game simulation logic from dedicated server to shared client. WebRTC works great if you're doing p2p among browsers, which severely limits the kinds of multiplayer experiences you can create.

I love WebRTC and think it's great. I studied and read all related RFCs and tried implementing a stack in JavaScript for Node.js. Got stuck on DTLS, then switched jobs.

I do think WebRTC is "the future," but we don't seem to be moving AT ALL towards that future. Having multiple implementations would move the needle. Otherwise, there was this big leap forward when it was developed and added to browsers, but not much since.

Using unreliable or out-of-order data for game state sounds hard and difficult to test, no? Are there code level patterns that help reduce the complexity while keeping the possible performance benefits?

If your entity state changes ("move player 1 to 3,4", "open door 3") are dropped/switch order, the logic no worker works. This way the unreliability seems to leak directly to game logic/scripting layer.

On the face of it the complexity cost seems high for supporting bad network connections. A normal TCP connection rarely sees losses or reorderings. There are exceptions (twitch games) of course.

Finger Trees: A Simple General-Purpose Data Structure (2006) city.ac.uk

keith_analog 1 day ago 1 reply      
A few years ago, our research group published a data structure, called Chunked Sequence, that is similar to the Finger Tree. In short, Chunked Sequence features the same asymptotic profile as does Finger Tree (neglecting persistence) and, in addition, offers strong guarantees with respect to constant factors. Very roughly speaking, Chunked Sequence is to Finger Tree what b-tree is to red-black tree.

We've implemented Chunked Sequences as a package of C++ header files and provided source code on github. To the client, Chunked Sequence looks like STL deque, but with additional methods to allow split at a specified position and concatenate, both in logarithmic time. The operations which push and pop on the ends of the Chunked Sequence are approximately as fast as those of STL deque, and in certain use patterns much faster.

Finger trees are an example of a truly elegant functional data structure that can be used for just about everything. The problem is they don't match the memory model of real hardware so for all of their elegance and theoretical performance in reality they're too slow to be useful.
harpocrates 1 day ago 0 replies      
Given the number of comments about the inefficiency of finger trees: yes they usually have a high constant factor (for their otherwise reasonable asymptotic complexity) due to cache misses. However, they are immutable and persistent, which means they have efficient sharing, which in turn makes them good candidates for

 * use in multiple threads at once * code that needs to be proven correct (I believe the Haskell Data.Sequence implementation is a translated from Coq)

raphlinus 1 day ago 0 replies      
I looked at finger trees as a possible basis for the string representation in xi-editor, but ended up going with a simpler b-tree based approach. The better asymptotic bounds for doing manipulations at the ends are appealing in theory, but I never saw an actual problem with the O(log n) cost in practice, and it is possible to optimize the common append-only case a lot (I have a "builder" API but the current implementation is not as heavily optimized as it might be).

I _believe_ that the polymorphic recursive type, easily expressible in Haskell, cannot be expressed in Rust. You'd fake it by just using trees and having the shape as an invariant maintained by the library (just as the min and max child count constraint is maintained in a B-tree). I personally think that's fine, Rust wouldn't be a better language if its type system was made even more rich, but it's interesting to have examples so you know where the edges are. (there's also the possibility someone will find a way to encode it anyway)

This is a fun data structure to implement in Haskell, and I've always been curious about how one would do it in C++, largely due to the fact that

Has polymorphic recursion in the last case. What would be the C++ approach for dealing with this sort of thing? Pass in a compile time integer to represent the level of nesting?

The problem with using lazy data structures for storing things is that deletes don't necessarily free up storage. Fingertrees are fine when you need to store a collection in order to implement some algorithm (and being persistent makes it useful if this algorithm has to backtrack), but they aren't so good for backing a collection that changes over time, like the set of currently connected sockets in a network service.

But (and I'm sorry if this sounds negative but I'm just FED UP) I'm so SICK of freaking subscription services. Can't you guys just rely on interested customers coming back if they want to? The way I see it, there's absolutely no relation between the message you have on the site to teach people electronics and make a few bucks while you're at it, and the need for customers to have accounts, registration, subscription and all of that crap. Just let me buy the kit I'm interested in and be done with it! With so many subscription services around, I'm following a policy of immediately disregarding anything following the same model, specially if there's really no need for it. Make a one-time purchase option, with no registration or crappy spammy emails and I'd be interested (yes i know you won't share my details with 3rd party but you'll hammer me with emails on every freaking occasion I know.)

My issue with learning electronics is that there's a steep gap between "plug this into that" and "plug this into that because x". I want to learn how to reason about the latter. Most resources I've seen like this don't give you that, they just have a bunch of prefab projects and lead you through them with the former strategy. Fortunately I've been able to learn some of the latter on my own but it would be great to see a good resource for the former.

I know how to program. I don't want to program a microcontroller to do all of the work. I don't want to build a "WiFi robot", I want to build a simple circuit with a few LEDs and understand completely how it works and why it was designed that way. I want to know how to choose the right batteries and resistors, or what components I need for arbitrary projects.

One project per kit is a problem because you can't just move on to the next project. You get stuck and frustrated. I find dealing with that frustration is a big part of technical learning for beginners that lack confidence. with a kit that gives you a lot of projects you don't go to bed feeling dumb like you can't do this. This matters. At least to me.

So boom! there are at least three of these, thimble.io, hackerboxes, and Adabox. They are all basically the same idea, every month a new "kit" of parts etc comes in. You open the box, you use the parts to build something, and then in another month something else shows up.

The weak spot in all three seems to be the curriculum.

So in general I love that this takes the 'get the stuff' problem out of the way. Sure you can buy a book on transistor projects or computer projects, but then you have to source the parts and move from there. The same issue happens with the "starter kits".

Back in the 80's and 90's a number of people made "<some#>-in-1" electronic boxes. These usually had the components mounted on a substrate and usually came in two flavors, in the first flavor everything was mounted on the substrate and you just stuck wire between springs to make your circuits[1]. Then they added a breadboard and you could wire up the basic circuit on the breadboard with the knobs and such around it[2]. And then even some compute stuff built in[3].

So what generally makes these things engaging are either they are easy to start and get more interesting as you build on your knowledge, or they culminate into something useful. There was an RCA technician training course where you built all of the components of a color television and then assembled them into the final unit[4]. You got a color TV out of it and a lucrative career in television repair :-).

I'm not trying to be dismissive of this idea, I'm trying to say that these ideas work best when they have an editorial position, a path, start points and end points. Imagine a web design "box" type product where each month you got a box with some aspect of web site design. It would include exercises and text book type material, quizzes and working problems so that at the end of each month you had mastered some part of the web service stack. So perhaps your first month would be about putting up a web server, the second month about getting keys so that it can be secured with SSL, then the third month CSS that helps style the pages, and the fourth month maybe PHP or a JS module. Each month with a digestable bit that assumes you're going to spend perhaps one or two evenings a week on the material. At the end of the year you have a full web app deployed on a droplet or something. But every month you get something that works and something that builds on the overall thing.

Electronics can do that if you pick a specific area of interest, so sensors or computers or radio or audio.

An editorial spin like that could take the box idea and take it to a whole new level I think.

Worth reading Tim Wu's "The Master Switch". He has a chapter that discusses the early history of wiring up the United States for telephony and how in the 1890s many of the early telephone lines in rural America were run by farmers (based on cheap "squirrel line" wire often just nailed to existing fence lines).

This is followed by the inevitable buy out of these rural telcos and the even more inevitable shuttering of what (for AT&T) was unprofitable business.

My mother lives out in the boonies of rural Oklahoma, and until about five years ago, had to make-do with 28.8 (on a good day) dialup.

She now has up-to-3Mbps/1Mbps via a WiMax antenna on the roof, pointed at another antenna on the water tower of the nearest "town" a few miles away. For this, she pays $65/month.

It's expensive, but it's her only option. If she lived just a few miles in another direction, she could get these awesome DSL prices (from her ISP's website):

"Extreme Package = 5 Meg bps at $84.95 per month

Premium Package = 3 Meg bps at $64.95 per month

Gold Package = 2 Meg bps at $54.95 per month

Silver Package = 1.5 Meg bps at $44.95 per month

Bronze Package = 512 Kbps at $27.95 per month"

I've seen firsthand how difficult and time-consuming the buildout is of Google and AT&T fiber is in Atlanta. Idle fiber runs just 100 yards from my house, where it's been sitting for months. Just for this single run it's required dozens of people, traffic permits, closed roads, sidewalk repair, new access panels embedded in sidewalk, let alone pulling the fiber itself.

At the phone poles there are large devices (repeaters?) and I assume more equipment at the nearest colo.

This is all on a street that already had a lot of infrastructure and easy access. I haven't seen a single run through people's backyards in a hilly, densely populated neighborhood. It's going to be difficult.

As a person who was born and living in a country which has no tipping culture.The tipping sucks.

I should have been fully informed how much should I have to pay before I purchase something or some service.Any extra demand from agreed amount should be illegal.

I also don't want to waste my precious time on paying the tip for calculating tax.

The worker's salary is a employer's responsibility.If the the worker become underpaid without the tipping, then the worker is underpaid by the employer.

Tipping is also extremely inconsistent in at least three ways.

One is the idea of a percentage: how does that make any sense? When I go out for a rare nice dinner and the tip alone ends up being $20 or so, I ask myself: did this person/restaurant really do any more than the server of the last entire meal that cost $20? Of course not, and yet somehow it would look weird to pay $40 for a $20 meal with tip, for the same service?

Another inconsistency is where to tip. Yes, tip at restaurants but what about the zillion other places that sometimes explicitly and often implicitly expect tips? Do we have to slip a dollar to just about everyone in case they expect a tip?

And finally, the inconsistency in who tips. Sometimes I tip generously because I assume there will be other people who just dont tip at all, or tip poorly, and I feel some obligation to balance the pot. I dont know why, it just seems like the right thing.

It would make a lot more sense to end all these charades and just show exact prices. (While were at it, lets make sure utility companies do the same, up front, no fees.)

Having lived in Japan for a long time, I kind of dread visiting America because of the whole nonsense of tipping (and lot of other reasons, really). There's simply no concept of it here and yet the service is excellent. I don't know what the typical wage is but I know people who work in service jobs and seem to have a lot more disposable income than their counterparts in the US.

I also know people who work as servers and bartenders in the US and (predictably) they hate the idea of ending tipping even if it means a higher base wage. I suspect they're wrong but then I don't have to walk in their shoes.

oddlyaromatic 1 day ago 2 replies      
Here's a pickle: I agree with the direction of this article, but I don't agree with most of the individual points and statements. I think the expectation of tipping in the US is in general a bad thing, but has enough upsides for business owners and some higher-earning servers (and even some customers) that it will be hard to dislodge. I also think the incentive for any business to change is probably not as high as the author's wishful thinking makes out.

I mostly disagree that "its robbery", or it's some kind of unpleasant surprise at the end of the meal for the customer. Tipping is not a secret. You know it going in. You might not like it but it's not a new thing that gets sprung on you at the end of the meal. If you can't afford to tip at the level you want to, you probably won't enjoy eating there. It is too costly for you regardless of the printed menu prices, because you know in advance that if you experience service you really love, you're going to be delighted and you'll want to be generous with a tip - but if you feel like you can't afford the extra 20%, that will be unpleasant for you and the server.

Printed Price + Tip + Tax is the cost of many services in the US. It is not an ambush. I still prefer non-tipping cultures, like where I grew up, but I accept that this is the real cost of things here.

There are complexities related to the psychology of putting cheaper prices on the menu than you really end up paying, I agree with that, but it is not as simple as many of us seem to think.

Much of this article, and many of these comments, seem to ignore the realities of the complicated and entangled cultural accident that tipping the US is. It might be better to unravel it - but it will be difficult, and it will have costs.

I read an argument once that that tipping is probably illegal under US employment law because, in practice, its racist. Research indicates that servers who are ethnic minorities are tipped less than white women, who are tipped most. Sure the employer isn't doing the discrimination themselves but they are setting up compensation scheme that, in practice, is discriminatory. This is called "adverse impact" in US employment law and is still illegal, there doesn't have to be intent.

Maybe challenging tipping in court would be the best way to eliminate it. I'd be interested in reading the ruling no matter the outcome.

EDIT: Quick Google, Here's some research on the subject http://scholarship.sha.cornell.edu/cgi/viewcontent.cgi?artic...

As an aside, I actually went to a pretty expensive restaurant where the busboy did most of the work. The only thing the waiter did was take our order, ask if everything was ok, asked if we wanted another (paid) drink (the busboy refilled our water several times), and brought us the check. They busboy did everything that wasn't money oriented. I asked him if he got tips, he said he got 10%. 10% of the compensation for at least 50% of the work! I noticed all the busboys there had something in common - they were all black teenagers. The waitstaff also wore button down shirts and ties and the busboys wore polo shirts. I was extremely uncomfortable with the situation.

This works perfectly well in Australia, where tipping is entirely optional and not necessarily expected - however can still be done, if you feel like it.

In the advent of tap based payments especially - which is now ubiquitous in Australia - and you just tap your phone / card / device to the terminal which already shows the bill, I'd say tipping happens mainly in higher end restaurants.

There's certainly no lack of restaurants in Melbourne - with plenty of people enjoying the vast array of options for eating out. I for one am happy to not have to worry about tipping on everyday meals, however on special occasions I will add say 5-10% if particularly pleased with the service.

FYI - I never felt uncomfortable to tip in a restaurant. I go even as far as that I don't dine in restaurants which have a no tip policy or where the tips go to the owner instead of the staff.

Also, restaurants already charge a fair price. It's one of the longest running industries and they do still pretty well, so clearly they already ask a "fair" price for their phos. The wage for a chef or other staff is not determined by the menu price but by the market rate. If you have more people who can cook than people who need a cook then it's a bit tough isn't it.

Tipping is about the perception of social class and giving the buyer the perception of having power over others, by giving them a mini power-trip.

In no other circumstances is a unilateral and after the fact negotiation acceptable. Would YOU work for a variable salary with no clear criteria on what affect it, no guarantee of salary regardless of your skills an effort and for which studies have shown that the colour of your skin, your sex and the mood and social background of the customer has more effect on your salary than anything else?

If the service and the food is good, I tip 15% and go back for more and talk about it to everybody I know. If the service or the food is bad, I tip 15%, never go back, and let everybody I know, know about it.

I think that tipping as a percentage of the meal cost is absolutely idiotic.

I have never gotten good service at an expensive restaurant, and yet the receipt gives you the math for 18%, 20%, and 22% tips.

I have gotten good and bad service at cheap restaurants (something like Steak and Shake), and tip accordingly.

The "work" is not anything different between the two jobs. Just take my order, bring me my food, and refill my water glass (heck, leave me a pitcher of water and I'll be much happier and do the refilling myself!). Why does the expensive restaurant expect a $10.00 tip for this service, while the cheap place is happy with a $2.00 tip for the same amount of work?!?

A lot of the advice here is good and has nothing to do with tipping. Pay your staff well, don't add service charges (adding "fees" for "health care" is a counterproductive political statement), just charge a fair price that covers your costs. I love going to places that include sales tax in the advertised price. I would never return to a restaurant that nickel and dimed me for their health care expenses.

But I also love tipping generously. I don't believe poor service should be punished with a poor tip. More likely poor service means your server is also having a really bad, overworked day and deserves the tip more. But I guarantee if you tip well every time you go to a local restaurant regularly you will get spectacular service after a few times.

As for non Americans who are confused by tipping, it's no more important or intimidating than typical expected manners in other countries. In Paris shopkeepers expect you to say bonjour and au revoir and cashiers expect you to have exact change. There'll always be cultural gotchas when you travel. If you're unsure whether to tip it's totally acceptable to ask.

The problem with no tipping, in my experince (especially in Europe), is that waiters aren't incentivized to turn tables. If you go to a popular spot for dinner that happens to be completely full and ask for a table, the waiter will usually shrug their shoulders and say 'Sorry, try again tomorrow.' Usually, there is no concept of a waiting list or a waiting time estimate, because diners are conditioned that they can spend 3 or 4 hours over a bottle of wine, and there would be no pressure to pay and leave, so waiters find it impossible to make any promises regarding when a table would free up. Additionally, the waitstaff won't be paid extra to make an effort and try to serve more tables on a given night (being on a fixed salaries), so they'll be quite leisurely about their business.

Of course, if you happen to be the one who got there early, and you like having 3-hour meals while chatting with your friends, it's the perfect arrangement, because nobody will pressure you to eat, pay, and leave in 30-40 mins as usually happens in the US.

From personal experience (just anecdotal) I would say service in the US is much better than for example in the Netherlands (my own country). I think you'll have to think of other things than service to make this happen.

Other options:

+ Start with clear signs to indicate for other businesses (cabs, hairdresser) that tips are not expected.

+ I will assume that you pay the 20% to your personnel anyway. So basically you offer a guilt-free paying experience. We will genuinely be happy by whatever you pay.

+ The international card. Communicate that you don't want that Americans are the only ones paying 20% more.

+ Build up a name as employer. Advertise with that.

+ Mix and match your service offerings with others, being a library, place to date, etc where tipping is less obvious.

+ Have people pay online before the meal. Subscriptions is also possible.

+ Uber-experience. Do not pay the restaurant directly, but have intermediate company taking care of it.

This essay left me confused - it starts by suggesting that tipping is bad, and that raising prices, possibly above the cost of tipping, will bring a net win. I was very curious to read about why.

But then the essay shifted to two seemingly unrelated reasons: (1) if you make the food delicious and the service great you can charge more, and (2) if you pay the kitchen staff more, you get less turnover/happier cooks. These last two don't support the central thesis - why does ending tipping help cooks get paid more? At the end of the day, fixing all other costs, cooks get paid more if servers get paid less, whether that's from ending tipping or increasing chef salary. And obviously making delicious food would be great, but what does that have to do with tipping? If you end tipping, suddenly everyone will try harder?

An article examining the effects of increasing chef pay at the expense of service pay would be very interesting to me. I would gladly sacrifice some professionalism in service for increased food quality, and I wonder if others would, too.

I used to hate tipping but now I love it. I spend >100 nights/yr in hotels, and tipping the bellman/doorman well on the way in is one of the best investments in a good stay (calibrating tips for the point where he gives you his name, and ideally phone number, for "if you need anything else"; $10 in most third tier US cities; $20 in a place like New York). Las Vegas basically runs on $5s and $20s -- everything from "valet lot is full but we can keep your car right here for you" to moving carts full of pelican cases to getting vehicle maintenance done to whatever.

In the Middle East/Central Asia I am very happy to be "the American who tips and is polite" vs "the American who is worth $5k if we call that guy...".

In China I had hotel staff literally spend the afternoon with me navigating Beijing police to recover a $5k loss (successfully; btw Beijing tourist police are awesome too.)

Tipping reasonably well at restaurants/cafes you frequent (I try to pick a couple per city) makes getting tables, impromptu meetings, etc much easier to set up.

If you view tipping as an obligation it sucks, but once you view it as a chance to get what you want it is great.

Maybe I'm ruining it for everyone, but when I've gone to New York's budding "no tip" restaurants, I've thrown a cash tip on the bill.

Guess what happened next? I was asked my name, and the next times I went, I got seated faster, comped chef's recommendations and a generally friendlier interaction with my server. Same thing happens abroad, where the locals don't tip well.

I don't understand how people get shocked by fundamental rules of incentives.

(Side note: this works everywhere. No, I don't put cash on my banker's or retail clerk's counter. But I do make an effort, particularly when doing things they'll earn a commission on, to do my business with them. In exchange for the minor hassle I have a better experience and get an enjoyable relationship out of what would otherwise be drudgery.)

Anecdotal, but there's a supermarket chain in the Southeastern U.S. (Publix) that pays their employees a living wage, provides health coverage, and makes a point of letting the customer know that staff (even the folks that load your groceries into your car) doesn't accept tips. The food costs are a little bit higher than, say, Walmart, but closer to that end of the spectrum if Whole Foods is the opposite end. I don't know how well that model would translate to the restaurant industry but, personally, I would give preference to establishments that opted for that model than the current $2something/hour minimum wage + tips.

Back of house staff, in the US, cannot tip share. Its against the law. Assumedly this was originally meant as a worker protection, but in recent years, especially at higher end establishments, it acts as a wage limit for the people making the food.

We should change the labor laws for restaurants to allow for both worker protections (restaurants are notorious labor law violators) and to allow back of house staff to get some of the tip income.

It doesn't matter. People will _still_ tip. While the vast majority of us _hate_ tipping, there are some out there who absolutely live by it emotionally (I'm talking about the tippers here), and maintain a healthy amount of guilt if they don't tip.

Case in point: One of the biggest wins of Uber was to remove the tip concept from getting a ride. It made the whole experience effortless and seamless. Portland being Portland, however, has drivers who post placards in their cars suggesting tipping (against what I thought was company policy), and riders buy into it, as you can't possibly exist in Portland without constantly trying to be the nicest person on the planet.

Mark my words: if this happens, restaurants will charge 15-30% more and we will simply start tipping on _top_ of that.

Hell, even during my last trip to Germany, I noticed an expectation for tips.

editorialized title. Tsk.

the tipping situation sucks, but the larger economic problem is effectively due to rent extraction by the landlord. when a restaurant can't afford the rent that, say, a bank can, they are effectively priced out of the market. All excess returns and up going to the land owner. This effectively becomes a variant of baumol's cost disease. Once again, return on capital trumps return on labor.

I remember, many years ago, living in Manhattan: in a short period of time, for restaurants on each corner of an intersection were replaced with four banks. A vibrant spot died.

I lean toward agreeing with this article, however laws would probably have to change in order for it to work. Raising prices, say by 20%, and passing that money directly to servers is fine IMO. That would not only eliminate tipping, but really invest employees in the success of the restaurant. Further, the restaurant could decide the "tip" portion of the price on expensive alcohol as well, eliminating the ridiculousness of calculating the tip for the food and alcohol separately (many people don't tip the full 15-20% on very expensive bottles of wine, for example).

Where this falls down is that tax would then be charged on the raised prices, meaning we're now paying a tax on the "tip". I think many people would find that hard to swallow. So it's a good idea, but local and state tax laws would have to change.

Including "tips" (you could still tip for extraordinary service) as well as sales tax in the price might be the first step towards more transparency and fair pay for everyone involved (owners to waiters) in what essentially amounts to a luxury service anyway.

I'd rather tip than get a bill with service tax included, which is itself taxed by the state authorities. If the service is crap, my tip is going to be zero. What sucks is restaurants that share the tip between employees, which means unmotivated employees get the same amount as the motivated ones. It's also a cultural thing - in Southern Europe there's a strong tipping culture. In Hungary you get a service tax on the bill instead. In Austria they will thank you and look extremely grateful for a tip of even one cent. Optional is good. No tip is fine as well. But don't tell me what to do and especially do not regulate tipping.

Tipping is great because it provides the customer with some leverage to pay a price they feel is fair. Not to mention it allows many many many many people to live somewhat comfortably despite working in what would be considered a lowly occupation. We haven't even talked about how service workers are salesman and saleswomen who are provided the opportunity to be compensated more for greater achievement, and the business in turn as well.

It sounds like the people who dislike tipping are the same people who struggle to stand up for themselves to salespeople, and feel pressured to pay extra just to remove themselves from the social setting. I don't mean to be accusatory, but I believe it's likely this is a major motivating factor to dislike tipping despite the complete advantage it gives to you as a consumer.

I think the title should say "Having an expected floor for tipping of 20% and tips of 30% for excellent service, is not a better incentive for good service than a floor of 0% and 10% for good service".

Removing (banning) tipping all together in a restaurant is doable, but as an owner you may want to ensure you have incentives left for employers (e.g. let customers anonymously rate the service after online bookings and hand out bonuses etc).

I prefer the normal system where staff is paid in full (so no part of their expected income is tips) and customers tip for good service. This is how it works in most of the world.

Jobs that have a high component of tip income, generally tend to be low wage (total comp), seasonal, have high turnover, employ younger workers (again, generally), and are transaction oriented.

With the above in mind it makes sense to use tipping to align enployees and management in a situation where management can't spend the time developing/micro managing its employees

You think the average teenage valet is going to run for your car on a hot day if there is no tip?

Any consideration of tipping has to take into account the fact that it lets owners shift risk to their employees (since more of a slow night will come out of their pockets instead of the owner's) -- especially when laws specifying that employers have to make up the difference if a wage with tips is less than minimum wage are poorly enforced.

Let's be real here. The reason these stories are popping up is that the restaurant industry is getting squeezed, hard, by supermarkets that are moving towards prepared foods as online delivery starts to nip at their business.

Restauranteurs at mid priced places want to capture more value. No tipping means that the waitress currently pulling in $20-30/hr makes $15, and they pocket the difference through higher prices and shrink-ray.

All of these ethical arguments, armchair economic dissertations and tales of tipping PTSD woe are nonsense. It's all about dollars and cents for yet another dying industry.

> what if we were to magically make tipping disappear?

Tipping is nonexistent in most of Europe, and guess what: the service absolutely sucks as a consequence.

Why would waiters go out of their way to please you? They don't make more money doing so. So your orders take forever, waiters never smile or even show any kind of a pleasant attitude. It's a terrible experience all around.

Tipping is awkward and the fact that the prices you see are never the prices you pay is annoying, but it has upsides.

It's amusing the way everyone who lives in tipping countries swears by how much better it is and how much they prefer it. And conversely, people who live in no-tipping countries say the same about their system. Most people simply like what they're used to, and don't bother considering the other side of the argument.

In my own case, I live in a tipping country. I find that I have maybe ten restaurants I frequent. And since I've been here for twelve years, I constantly run into the same waitstaff. Incredulously, I once ran into the same waiter at three separate restaurants in my time here. If I were to give one of them a bad tip for bad service, there's a good probability I'd end up having them serve me again, and that does not sound pleasant.

So the tipping is basically mandatory for me, unless I'm willing to never eat at a place again. And to date, I've left no tip exactly once for a waiter who took our drink orders, came back ten minutes later to say there was a problem with the machines so we asked for water and took our order, the backstaff brought out the meal, and we finished the meal without ever having received anything to drink, and had to ask the staff at the front for our check because the waiter never came back. Another time we left a bad tip and never went back to a restaurant that made us wait over 30 minutes in a near empty place before anyone took our order. The staff knew we weren't served, and the longer they waited, the more awkward it became, and we kind of both decided we weren't going to leave until they served us.

It's also strongly worth considering some of the racial undertones of tipping. It's pretty well regarded among waitstaff here in the US that black people don't tip well, and as a result, they receive worse service, which in return leads to worse tips. It's a self-fulfilling circle.

I can imagine myself as an employee. If tips are resulting in huge paydays, I'd obviously prefer that system. But if I were constantly getting highly variable paychecks, that would be a big problem as my landlord wouldn't take a smaller payment because business was slow this week. A steady income provides much-needed stability.

I can also imagine myself as a customer. A tipped waiter would try to upsell me more and push wine on me. Yet a non-tipped waiter might not be as attentive since there's nothing in it for them to do a better job.

Weighing all the pros and cons, I'm personally of the opinion that we should abolish tipping, abolish the $x.99 bullshit pricing and just say $x+1, stop charging $2-3 for a ten-cent soda to subsidize the food prices, and roll taxes into the prices so if it says $10, you pay $10, period. Leave "how'd we do?" cards that customers drop off into a sealed box on the way out to control for good service.

But, I doubt I'll live to see any of that here.

I agree with the author. Having lived in Japan for a number of years, where tipping isn't done, I can say that the dining experience is far superior. Servers don't have to feel like beggars and patrons don't have to feel like their being panhandled.

I also agree that nothing screams "I'm a sphincter!" quite like asking for a 20% tip on a muffin, or a cup of coffee. Unless you physically came to me, got my order, and brought my food to me, you don't deserve a damn tip.

Another thing that restaurant owners do that is deserving of a throat-punch is to confiscate tips and dole them out to other workers, or divvy them up evenly amongst the servers. When I give someone a tip, it is because they've done a good job, and I want to show THAT PERSON my gratitude. I'm not remotely interested in helping the restaurant owner make payroll. That's not what my tip is for.

Tipping sucks and it is grossly abused throughout the restaurant industry. I'd be happy to see it die a deserved death.

You might argue that this is stupid, because it's a catch 22; unless everyone does it, you lose as a business if you do it; nothing motivates people more than raw dollar value and you'll either lose your staff or have to put prices up to pay them more.

...but, you look at Uber, and there's no tipping there; and it's great for the consumer, and (astonishingly) drivers seem fine with it, despite objectively being exploited blatantly and paid less than taxi drivers.

So, maybe there is something to be said for an all digital disruption to the food scene, somehow...

Honestly, I can't see how it would work though; you have to actually demonstrate that your new 'no tip' solution works somehow, not just armchair philosophize about some way to 'magically make tipping disappear?'

The idea of separate charging for food and service acknowledges a certain orthogonality in the two activities, and also offers the service staff a measure of unbundled independence, in the diner's perception. It reflects the tradition that serving food professionally is a real skill and is partially unrelated to the food itself.

in France 15% service charge ivs built in, it means service staff are professionals as they get paid properly, and I never experienced diners convincing themselves that the meal was bad as a result.

Personally always find this moaning about tipping, which seems to afflict a large though thankfully not majority proprtion of the population, selfish and small minded.

If you don't like paying for a genuine service, ie. someone at your beck and call, stay at home.

I have to laugh at people who wring their hands over tipping at restaurants. The guilt and anxiety that the custom of tipping induces is kind of silly.

There's a simple calculus to tipping that some people just can't seem to stomach:

 Tip based on the amount they'll spit in your food.
That's what you're paying for. Clean food.

In general, the reality is that tips only improve service after a customer or group has been recognized as a good source of tips.

Tips are bribery, not commission. Once tips are recognized for what they are, the motives for all participants becomes clearer. If they're never going to see you again, a good tip is rendered meaningless.

Having worked in the restaurant industry for over 12 years, started as a bus boy at 15 years old, then waiter, then bartender and finally moved to General Manager of the whole place. I can tell you that tipping is absolutely necessary.

I can say that the article is dead wrong about this. Tipping is the best thing that's ever happened to the US Restourant business. Especially at great establishments with repeat customers.

Here are a few reasons:

1) As an owner of a place there is only one of you, impossible for you to cook and go greet the guests and do everything to make them feel special. Your staff, the waiters the bus boys will feel like owners through tipping. If they do a shitty job they don't get paid, it doesn't get more capitalistic than that. It's the the same thing that motivates employees of startups that have equity.

2) For customers Tipping is not required if they do a shit job you don't have to tip 20%. Leave 10% or less, that's the whole point. You as a consumer have the power. Not the owner or the staff.

3) The math is a bit annoying but most places will put the math in your receipt.

4) The best establishments with repeat customers benefit from tipping the most. The waiters and staff have to treat your guests very well and it is in their best interest to keep high paying, high tipping customers happy and coming back. The waiters will complain and fight with the chef when they do a bad job that's how much they care about things going well. Their livelihood is at steak.

5) Now compare waiters in good establishments that get good tips to folks working at McDonalds. There is no comparison, the waiters are motivated the McDonalds worker gets paid no matter what and makes no tip. No extra effort necessary. For that matter compare them to any worker hat dosent make a tip and doesn't have to hustle.

Anyway, I am a bit too passionate about this but the author is very wrong on this one.

Tipping creates a common goal among the owner and all the staff it is crazy to ever think of getting rid of something that makes your employees work harder and better and is a carrot and a stick that gives the consumer all the power.

Tipping is essential. It's the most common generosity exercise in everyday life. It gives us a chance to flex a muscle we don't flex often enough.

We should be doing it more, not less. We should tip the cashier at the grocery store and our mechanics and our mail carriers and the referees at high school sporting events.

Paypal tip jars and Humble Bundle's Pay What You Want model are two examples of tipping on the web that I'd like to see more often. The more nudges toward generosity, the better.

The article is missing a bit, since Word for Mac (1985) was more the model for the eventual Windows 1.X version, but isn't even mentioned in the article. There were also versions for other "windowed" OS's during the same 5 year period before Windows was sufficiently viable to make it work. People often forget that new apps appeared first on the Mac until around 1990 or so when Windows 3.0 shipped (Word appeared a bit before); basically MacOS was much more advanced than Windows up until that point. After Windows 3 the first platform flipped completely to Windows. I shipped my first MacOS app in 1987.

My goal for 2017 is to fully figure out Docker.

The majority of information out there, including tutorials and blog articles about others' successful deployments, comes in the form of very high-level overviews. Everything I've found is an introduction to getting a basic docker instance running. There is very little useful information out there as to how to run a proper multi-host cluster.

There is core Docker. Tack on docker-machine, docker-compose, Swarm, and the dozens of 3rd-party cluster management abstractions such as Rancher - and the intensity of the headache never stops growing.

It sounds wonderful, but there is so much to learn to be able to tackle a full production stack. It's one thing to successfully launch a working cluster after hours of manual tinkering. It's a separate beast altogether to fully automate setting up a new cluster by issuing a single command, taking into account consistent configuration of: secure networking, persistent volumes with backups, deployment of container configuration and VCS codebases (ex: nginx vhosts and your code itself), etc.

My goal is to set up an entire project in such a way that there is a single suite of automation that can deploy all environments: development VM, staging, and production.

Confidence - never thought it would be an issue when you're leading your own company. I quit a great job on the east coast in 2012, went to grad school and moved to Silicon Valley after graduation (2014) to work on my startup. I've been learning and building constantly for the past 4 years. I would rather my work speak for me, so I don't draw any attention to what I'm doing or to myself until I have great results to report. I don't have a co-founder because the people I would ask are not financially independent enough to take the risk without a salary. I'd rather make some money and hire them with as much equity as they can handle.

My first project stalled because of poor architectural decisions that overlapped with not-yet-profitable product-market fit (and too much networking instead of product work) and a baby. I learned that lesson and turned into a hermit to rewrite it completely - the market is there, but not immediately lucrative. I'm also writing something that makes money first. I'm hammering day and night with nothing else in my life but my family and the product. My second project is written in GO, wonderfully cheap to run, and about to be ready for launch. Not sure how to turn on that swagger button yet.

Selling to customers is one thing, but how/when do I start selling to investors and employees when few people know me in SV because I've been hammering instead of networking for almost 2 years straight.

Economics. I have started to get interested in them in 2016. Like most topics I get into, I started by looking at the history of the field. I also read Basic Economics. Now I would like to start taking actual lessons, either Coursera or maybe even physical classes at some point, if I can find good ones compatible with my work schedule in Paris.

I also want to get up to date with the most important advances in my field (distributed systems and algorithms). I did follow research in 2015, but not in 2016, so I have to catch up a bit.

I want to learn and play with LoRa. It's a 'IoT' technology that allows you to communicate over long distances using amateur (unlicensed) radio bands. Some of my friends have achieved distances of over 40km, and I'm curious to see what I can do with it.

So far I've been able to get a ping between two modules over a 10m range. Next up I'd like to transmit some useful data over longer distances (temperature for example), and then move on to devices that provide useful data (eg when a train passes a certain point to see if it's on time).

I'm coming 20-30 years late to the "biology is the future" mindset.

In my case, personal health has left me no choice.

Some poor medical advice and treatment, combined with my adversity to the whole topic -- yes, strong squeamishness combined with fear/observation that thinking about adverse events seemed (seems!) to instantiate them. That all has left me with a substantial health burden.

Meanwhile, in my experience the current U.S. health care system seems to be -- technological "miracles" aside -- making getting effective treatment ever more difficult.

So... As with everything else, it seems, you can't rely on expert consult -- even when you can afford it -- but rather have to learn and do -- or at lease prescribe and manage -- everything yourself.

So... biology. In other words, I need to belatedly read up on the owners manual. And find some hacks that help me.

As an aside, we're about to the point of molecular programming. So, maybe this will coincide with the current leading edge in technology, anyway.

I've moved to the Netherlands alone less than 6 months ago - so Dutch is high on the list of things that I want to learn (I can read it pretty well already, but I can't speak or write it very well). I'm using Duolingo, plus I have some Dutch friends already who help me out.

On top of that I want to learn industry game development techniques, including finally getting a solid grasp on C++. I've got a pretty strong grasp of systems engineering concepts and memory management since I'm very active in the Rust community but by the end of the year I want to be qualified to get a job in the games industry. Web development is not going to be my career, that's for certain. I'm reading through various maths-for-computer-scientists books, and I've got a bunch of highly-recommended game dev books (Game Engine Architecture, Real-time Rendering, looking at getting Real-time Collision Detection) in my library. I was an avid amateur mathematician in a past life, so although I'm rusty I'm getting back into my stride quite fast. If anyone has more tips on how to get your foot into the door in game development (engine/tools development, very specifically _not_ programming the game itself) I'd be extremely grateful.

I went through this last year. After two false starts with something toward the leading edge, I settled on Emacs, Linux, and JavaScript. All of which I already 'knew' enough to get my face slapped. Photography got added without a formal application. Raspberry Pi sort of worked it's way in under Linux in the second half of the year. Since I haven't 'learned' any of them, I'll probably keep them around in 2017.

I'm also thinking about adding some 'classical' AI at the agent level of abstraction (not the lower DNN level). That probably means a bit of Common Lisp and an excuse for buying some used Norvig books. Like the formal topics from last year, this seems to be a domain that I bump into by trying to avoid it.

This thread is awesome, so much enthusiasm and curiosity.

I'd like to learn/do a couple things in 2017:

- An overview of college-level conceptual physics. Historically I've tried to leap-frog into advanced physics because my math is pretty good, but I end up missing out on the concepts. So I'll stop rushing and do it step by step.

- Deep learning and deeper machine learning. I'm pretty familiar with ML in general but have never had the intimate understanding I've wanted, nor taken the time to properly dive into DL.

- Bahasa Indonesia and Mandarin ^_^ (while maintaining the rest)

- Abstract Algebra and Information Theory

- Keep up the pace with reading interesting books

- Become more familiar with devops and systems programming (Docker, Rust etc...but not an expert necessarily)

As an aside, I'm also trying to improve my running, swimming, and martial arts :)

I'm sure other things will also pop up in time!

Math-wise, well, it's a matter of where I go to college, I figure it'll have a huge effect on basically everything that happens thereafter. I definitely want to continue on my path towards understanding the Weil conjectures and that kind of thing, so I plan to be able to compute sheaf cohomology for schemes by the end of the year and learn more algebraic number theory. (And maybe look at representation theory.)

CS-wise: learn enough ClojureScript to be able to make convincing mathematical (etc.) visualizations -- I recently got a taste of Figwheel+Reagent and I'm hooked! -- and be able to manipulate Haskell transformer stacks better.

Other than that, I'd like to learn some French (marathoning Engrenages was the best decision ever!) and not forget the little German I know.

I may just do the wim hof method sometime in the year. After a crazy 2016 where I let the information flood me, I feel that understanding and appreciation for things was low. My intuition says it might be better to focus on a thing a month or two (depending on how alien the thing is) to get to a place where the mind has adjusted its cache eviction policies and made the new item into L1/L2).

In terms of practical benefits, I still hunt for python idioms on a routine basis. Owning and flipping through a book occasionally comes to mind. Any suggestions? (I am pretty good with multiple years on the language across 2 and 3)

I would like to stop flirting with machine learning and just finish essential chapters from statistical inference and spend time on linear algebra. Then maybe I would try to understand backpropagation for real. Meanwhile, applications must continue to be built and I must learn effective techniques to preprocess data. I would like to do more work in Pandas and Hive.

I've found my notes to be a trustworthy friend. I need to set myself a reward system to inculcate a habit of writing more (daily thoughts, project ideas, blog...) (and on paper)

I would like to fingerpick a few songs I have in mind too.

This would be a good list if I go deep. Could I make space for haskell, clojure, scala? Probably not. Might just read Backus's functional language paper though.

- Bulgarian split squats, 4x12 50kg: I'll go with a somewhat linear progression -- work from 3x8 up to 4x12. When I do 3 workouts using 4x12, I'll up the weight by 2-4kg and start a new cycle.

- Books I'll read:

 1. Gdel, Escher, Bach 2. Black Swan 3. The Society of Mind 4. Code complete (I'll read a chapter every week)
- Finally learn about compilers/interpreters:

 1. Work through "Writing an interpreter in Go" 2. Work through "Language Implementation Patterns" 4. Work through "Engineering a Compiler book" 5. Do the Kaleidoscope LLVM tutorial in OCaml
- Get good at algorithms to have a better chance at landing a job in one of the the big 4:

 1. Work through HackerRank's Cracking the Coding Interview track: I'll do 3 challenges every day until I am finished. 2. Solve as many problems from LeetCode [1] as I can: I'll solve 2 problems every day. 3. Work through the "Algorithm Design Manual book"
- Really learn Java. Java 8 looks interesting and I see there are a lot of job opportunities for Java devs.

Looks like a plan!

1. I'm either gonna pick up Golang or Rust in 2017 and go all the way with whichever one I pick.

2. gRPC/Protobufs

3. Kubernetes is also on the list. I really wanna understand how microservices work in production (deployment, monitoring, recovering, debugging).

4. Practical Deep Learning (TensorFlow/Keras etc)

Any suggestions/guidance for any one of those will be really helpful.

PS: I'm from C++ and python background.

1) I'd like to learn how to create a programming language.

Nothing complex or groundbreaking, but i've always been curious about how that all works. Maybe if it works well enough (it won't) I'd even adopt it as a scripting language for

2) Game development. Either to really learn Unity or C++/SDL/GL but put out something that isn't utterly basic and pedestrian.

3) I don't know. Something new. I'd hate for my life to have become so predictable that I can easily predict what opportunities will arise or what the limits of my ability to learn will be.

I started bouldering in spite of my back problems because a college of mine needed company in the boulder-hall next to our office. Now I want to trade my drinking / women obsessed buddies for folks intrested in web dev side projects. It is quite lonely if you can not talk about your hobbies.

I'm planning on studying deep learning techniques and relevant literature so I can apply it to the generation of better phonemes for my Donald Trump text to speech engine [1].

I've also got a huge interest in film and intend to teach myself filmmaking. I've had an interest in exploring it since middle school, but I've never committed the time. This year I'm obligating myself to film and edit something short every weekend. I live in Atlanta and our film scene is burgeoning, so I'm also hoping to network with local filmmakers and students.

Anyone in the Atlanta area interested in either of these subjects?

TheAceOfHearts 2 days ago 7 replies      
I started learning Haskell this year.

One of the small bumps I had was getting my environment setup. Based on my experiences with Ruby and Node, I knew I'd want to have a tool for managing the language's version and dependencies per-project, so I ended up going with stack [0]. Arriving at that decision required a bit more reading than with other languages. Additionally, while setting up stack, I thought their docs were too long. They'd benefit from being broken up into more pages, instead of pushing so much all at once. With that said, the information presented in the docs is actually quite clear and well written.

Looking at the Downloads section [1] on the Haskell website, it looks like they've improved the docs since I last visited, but it's still a bit confusing. What's the point of Haskell Platform? It looks like it includes stack, which already covers all my requirements. Maybe it'd be useful to include a "why" section for each choice, to provide some examples of scenarios in which you might go with one choice over the other. Telling me what I'm getting doesn't give me any meaningful information if I don't know why I'd want that in the first place. I think there's too much information up-front, even though people landing there probably aren't equipped to make use of it. Why would someone pick the Haskell Platform option or the minimal install option?

While reading Learn You a Haskell, I used Haskell for Mac [2] for poking around. It's pretty great, although I didn't end up purchasing it, as I'm not doing anything that would benefit from using it.

Something I liked about Elixir is that you can just read their getting started docs and pick up Phoenix framework to get a web app up and running. That gives you a nice base on which to gradually build upon as you learn. Does anyone have a similar suggestion for Haskell?

The Haskell community identifies "no documentation" as a key flaw of their own community? I was going to ask why there hasn't been more uptake of Haskell for all of the apparently cool ideas that are there, but nevermind, I don't think I need to ask now.

Not having examples in documentation is a non-starter for me. It seems like there is a superiority complex there, that the Haskell community thrives on. That's ok I guess, I've never heard a practical use for it and I'm sure it will remain in it's insular state for the foreseeable future.

Out of curiosity what progress has been made in regards to improving the ergonomics of records in Haskell? Stephen references that an answer is in the works, but it looks like it has stalled out.

A nice summary. I'd also like to mention Don's talk again, which I feel should be added to the talk list, regarding the production Haskell we have at SCB: https://skillsmatter.com/skillscasts/9098-haskell-in-the-lar...

One thing missed in the various discussions of documentation here is that the Haskell ecosystem is actually highly variable in both the amount of and need for various types of documentation.

There's a pile of packages like diagrams (http://projects.haskell.org/diagrams/) or yesod (http://www.yesodweb.com/) which have tutorials, examples, books. People who have been working mainly with these should be completely expected not to feel much of a problem with the state of documentation.

There are also packages which have mostly/only API information. Sometimes, this tells you everything you need to use a package effectively. Sometimes it doesn't. And this is impacted substantially by people's level of skill -- at Haskell and at inferring usage from names and type information in particular.

There's room for people to have very different experiences

< A lot of industrial Haskell sadly still uses string interpolation for SQL synthesis, or fall back on libraries that use TemplateHaskell to unsafely lock a specific build to a snapshot of a database at compile-time.

This sounds kinda off-putting, but I'm not totally sure what it means. Are the SQL libraries for haskell comparable to e.g knex, or psycopg, or sqlalchemy? The bit about string interpolation makes me think that prepared statements aren't used?

I know I won't be thanked for pointing out non-technical infelecities in the writing, and I'm not a grammar nazi or anything but... "There was a lot of excellent Haskell writing this year. One cant possible enumerate all of them..." A lot of excellent writing is a singular noun, then it refers to "them", plural. Exactly the same mistake made in the next paragraph.

I don't want to be picky but if you're writing something public, learn how to use your language right.

There are some valuable resources listed here.

The field of deep learning is moving really fast, and a lot of that research is available on arXiv. Andrej Karpathy built a tool that surfaces interesting papers: http://www.arxiv-sanity.com/

r/machinelearning tends to vote up significant work and newshttps://www.reddit.com/r/MachineLearning/

And this list of papers may be helpful:https://github.com/songrotek/Deep-Learning-Papers-Reading-Ro...

For total beginners, we created this page: https://deeplearning4j.org/deeplearningforbeginners

Seems interesting. I haven't been able to look through all of the links, but I assume there are practical exercises and "homework"?

When people say "I don't do or have the opportunity to do ML at work" it's because they don't have data to analyze or actual things to program or do in order to gain the experience they need to make the videos worthwhile to watch.

If I were to watch 10 videos on ML, but not actually go write code or analyze data, then the videos aren't going to get me a ML job or be that helpful other than learning a little about the topic.

It's kind of like watching a open course on ancient history or some similar topic, but without writing a paper on it. Yes the video is interesting, but what gets me a job and experience is the thought and work that goes into the homework.

But even if these were just videos, it's a good resource.

I appreciate a list of ML learning resources, but does anything about this strike you as strange?

Over 9000 github stars and 1,260 forks for a repo started on 9th October????

It's great, but it's a mess - a heap of articles, github repos, books and such. A new learner can't deal with that. What a new learner needs is an interactive system to guide a learner through the process. Not a static list - one size doesn't fit all. I might know Python and not know math, another one might come from stats and Matlab but not know Python. One might know about SVMs and Naive Bayes but not about neural nets, another might have played with Keras neural nets but neglected to read up on basic ML. We need an adaptive learning system. Who's going to make one?

General ML question: is there some tool, supposedly based on ML, that can learn from my editing behavior, and automatically deduce and apply editing commands for repetitive editing tasks? This would be great e.g. when refactoring code.

This looks excellent, thank you for this! I actually get a chance to be involved with some very very basic/light ML at work, but i'm also completely new to the field. I really appreciate this style of guide, as i can hopefully jumpstart my knowledge, while i work to gain the required math knowledge.

The Math will be my most difficult challenge, and i'm starting to brush up / learn courses to hopefully enable the proper skillset. /fingerscrossed

Looks to be both a thoughtful listing of resources / tutorials, but also reinforces that to become ML capable, there is considerable effort involved. Things worth doing may require a lot of work, and I'm happy this wasn't another "Learn ML is 24 hours!" type resource.

The best board games of 2016 arstechnica.com

Anyone think recent board games are becoming unnecessarily complex and deeply strategy based? It could just be what I've seen from my friends but a lot of the times you can tell from the box art and title alone that you're going to need tiles, tokens, cards a 3 page manual and a practice round before you can even start. For me, that's a slog. It's too hard to hold conversation or focus on anything other than the game. I guess there will always be a divide between people who can spend 3 hours of intense concentration on a Settlers of Catan game and people who just want to play Jenga for a few rounds. Are there any popular simple games in the latter category recently?

I'm so happy with this resurgence of intelligent board games.

But as a fan I have to say, that board game is not based on Kim Stanley Robinson's trilogy. Because the game is about terraforming mars and not about politics, although there was a minor subplot about mars terraforming going on in the background of those books. Am I taking fucking crazy pills?

Nice to see The Networks by Gil Hova on this list.

I've been working on developing a couple board games for a couple of years now, and at the start of that campaign, I ran into Gil Hova's Bad Medicine on Kickstarter. On a whim, I sent him an email through his website asking for some advice about creating board games, not really expecting much of a response.

What I got was a 4-page email of well-thought-through answers to all of my questions, and a bunch of additional pointers furthermore. I met Gil at the Boston Festival of Indie Games in 2015. Super nice guy.

I have The Networks in my collection, but haven't got it to the table yet, but I eagerly await my first play-through.

+1 for Terraforming Mars. I enjoy playing it solo as well as with a group. There is enough variety in the cards to keep it fresh and the difficulty ramps up quickly.

I believe the best board games are timeless, as with music, books and many movies. I'm not too hip on the latest from the last few years, but ones I'd recommend:

Diplomacy. Axis & Allies (some variants more than others). Liberte. Illuminati. Ticket to Ride. ASL (esp SK's by MMP). Carcasonne. Empire Builder. Acquire. Puerto Rico. Dominion. Empire of the Sun. Uno. Fluxx.

What a dire list. The only game that looks interesting is Imhotep. Just a bunch of branded crap and stuff from celebrity designers that sold a thousand copies before even being released. The re-issue list is equally uninspiring, and they cannot resist adding yet another Rosenberg; one that I don't think was ever out of print for a moment. Schotten Totten is a good reprint, though (of something else that hasn't really been out of print for more than a few moments.) But, come on, Ra gets a reprint and it doesn't get mentioned? Shogun?
