Having lived in Japan for the past few years, I'm so over the tipping culture it's pretty hard to stomach when I go back to the States. Besides the issues it causes for employers that this article covers, I really dislike the power dynamics that it causes for the customers: but maybe not in the way you would think.

While the customer may be financially powerful in the relationship, I feel that tipping culture gives power to the server to withhold good service as a punishment or as an optimization strategy at their own discretion. It causes a server to judge you as soon as you walk through the door... will this person give a good tip? Should I ignore them and focus on this other table?

The worst part is that the tip happens at the end of the meal after all of the 'costs' of providing good service are already done. If the patron stiffs the server, then the effort was 'wasted.' It's far better to make an educated guess based on what? the way they dress? their grammar? the car they pulled in with?

It's a terrible system.

Back when I lived in San Diego I took my parents to the Linkery. The service was so bad it actually reversed my opinions against tipping. The servers clearly didn't care much about making us happy, messing up almost every aspect of the order. They put meat in my food - I'm vegetarian. My father got his food 20 minutes after my mother and I did. The waiter forgot one of my drinks. We called over the manager who offered us a free dessert to make up for it. Guess what? The dessert was on the bill. I'm always happy to tip 20+% for good service, but being forced (yes, we asked) to pay the service charge added insult to injury.

This is just one data point, but the Linkery was infamous around San Diego for having much worse service than other places in a similar price range. I'm convinced their experiment with tipping was correlated with this.

This is an odd title. The article gives an interesting explanation for why, theoretically, a restaurant would choose to go with a service charge rather than a tip-based system, but doesn't contain many observations from the now-tipless restaurant.

The whole idea of mandatory "service charges," or "fees," in any business, is kind of bizarre. It seems strange that we've accepted that certain types of businesses (airlines, hotels, ticket brokers, in some cases restaurants) should list prices that differ significantly from the actual price charged. There does seem to be some backlash against this practice: Kayak, Hipmunk, and many other travel sites now list the full price of airline tickets (though, often, not hotel rooms, with their "facility charges," whatever those are). And today I noticed that StubHub now shows prices inclusive of all fees. I understand why a business would like to list prices that are 30% lower than what the customer actually pays, but it seems a little odd that we're all OK with it.

I saw an interview recently with David Chang [1] who implied that part of the thinking behind the design of his 12-seat, 2-Michelin star restaurant Ko was an experiment in ways to improve the wages of his employees. Because KO is so small and the kitchen bellies up to the diners, the cooks are also servers and can legally make tips.

[Edit - Whoops. As a San Diego resident, I feel bad for neglecting to mention that The Linkery was awesome and like lots of folks here I'm sorry to see it go.]

It makes sense. Good servers are compliance professionals, whether you or they know it or not, and their pivotal role in the experience means that the good ones can make good money.

But I know that I've not gone back to restaurants precisely because I didn't like interacting with the staff, or I didn't like how they interacted with my guests.

And looking back, the most specific I could be about it was "well, the waiters were kind of intense." You know what I mean. They were professional, they did their job, but ... they were intense. And they didn't need to be; we're going to give them 20%, but they don't know that. So they're ... slightly intense, forward with their presence, so you won't dare undertip, instead of melting into the background and letting the food and ambience dominate.

In a restaurant like this guy posits, waiters aren't compliance professionals.

On the other hand, in a tipless restaurant, they aren't paid based on merit, so maybe they won't be as motivated to do a great job in the parts of their work that require concentration and diligence.

But they're doing a job that a robot should be doing as soon as possible, and a whether my server is good, great or okay isn't going to affect how my food tastes.

I have had consistently worse service from restaurants that I know share tips. There is no reason for a server to do better than their coworkers which brings everyone down to a common denominator.

This is in Massachusetts that does have a tip credit and where servers rarely get paid the statutory minimum wage if it is a slow night (against the law but it happens). Just for reference, the server minimum wage is $2.63/hour. If you can't make enough in tips because its a slow night and one of your coworkers is bringing the tip average down, your incentive drops off dramatically as well.

For something like this to work nationwide, the tip credit has to go.

If there is a flat 18% service charge, why not just add 18% to the base prices and get rid of the service charge? Or does a restaurant have to 'hide' these costs as an added percentage in order to make their prices seem reasonable?

Tipping is fairly rare here in Italy, and the food is "pretty good" - some might say excellent - even if there is a tragic lack of good Mexican food in this country.

I live in Denmark. Here tipping is almost not even heard of. Maybe our food just costs a little bit more, I don't know - because it doesn't say "+ 10% tipping fee" or something anywhere. Here you just pay the prices noted next to the food and drinks that you order.

And the kicker, the service is always good. Because if the server isn't nice, they'll probably get fired. Because guess what, serving food and being polite about it is their job. That is what they're getting payed for. So demanding extra money to do their job with a smile just seems too weird for me.

I like this quite a bit.

2 places have no tipping in New York City:- Sushi Yasuda - considered by some the top sushi spot in the city. (Certainly one of the most expensive)- The tap room at Whole Foods - let's just call it a little more lowbrow.

My budget hasn't encouraged me to visit Yasuda in several years, but I will say that I like not having to pay tips at the tap room. It certainly makes an inexpensive place seem even cheaper, and their service hasn't suffered for it at all.

Is there an inherent disconnect in being anti-tipping and pro-pay-what-you-will? How is a restaurant letting you pick your own price for service with the expectation that you will be fair different from a humble bundle letting you pick your own price with the expectation that you will be fair?

I'm not trying to be difficult or argumentative, I'm genuinely wondering. I'm pretty anti-tipping and pro-pay-what-you-will myself, and I'm just wondering if I'm fooling myself now.

alistairjcbrown 53 minutes ago 3 replies      
Coming from the UK, added service charges always annoy me (unless it's for large parties). A tip is something that I volunteer to express gratitude for a good experience. It is also something I can refuse if the experience is bad. Forcing a service charge assumes I will pay X% more than the price I have been shown regardless of experience.

However, that view is based on the UK system where minimum wage for the serving staff is enforced and where tip pools are allowed.

In his scenario the servers make $22, the cooks $14. Is that typical? There does not seem to be much incentive for a long time occupation as a cook.
mcphilip 57 minutes ago 2 replies      
On a side note, if you have a waiter or waitress that you particularly like and want to provide a tip that will not necessarily go into the tip pool, just leave a cash tip. This gives the waiter the ability to choose how much of the tip they report at the end of their shift.

Conversly, leave a tip on a credit card bill if you want to ensure that the entire tip is subject to any tip pool.

Notice that amongst all the discussion of money and wages, one thing that is completely avoided is any thought of operating on a lower profit margin. All the hand-wringing about poorly paid staff, but never once any thought about taking less money for himself to aid their plight!
dfxm12 50 minutes ago 0 replies      
It should be noted that the restaurant now charges a mandatory "service charge" in lieu of accepting tips. I put service charge in quotes, because in some jurisdictions[0], there is a legal distinction between a "service charge/fee" and "auto gratuity". If a restaurant automatically charges you gratuity (many do this for tables of 6 or more), you don't legally have to pay it. You do have to pay anything labelled as a "fee" or "charge" though.

[0] I have some knowledge of this in the mid Atlantic states, but the author is speaking about the West. Maybe it is different over there, maybe it isn't.

I never really understood the point of tips instead of just charging everyone the service charge. If it is some kind of feedback mechanism to the server for doing a good job, then why can't the restaurant just implement reviews?

A Passive Income Hacker's View on Wealth myles.io

jasonkester 59 minutes ago 0 replies      
That's a nice way to think about it. Looking back at the big "travelling phase" in my 30s, there were lots of years where I only grossed between $10,000 and $20,000 for the year. That was plenty, though, to spend most of the year living out of a backpack on some remote tropical beach. A lot of it actually ended up in savings.

That was contracting, so I needed to come back to LA to refill the travelling stack. It doesn't take much work to pivot that into a SaaS product or two that replaces the same amount of income. Again, maximising for free time and flexibility with profit being a nice side effect.

Then it gets really good.

noname123 24 minutes ago 1 reply      
I've had friends who tried to go the start-up route and didn't pan out; so they decided to do some affiliate marketing with Google Adwords, that didn't pan out. Then they tried to build a SaaS for developers to help with their development, designers to manage their CMS. So far, they haven't seen a dime. The only one success story I've heard said Google screwed up his search result ranking, so it only lasted about a year of supplementing 15% of his full-time job income.

I'd love to hear some passive income hacker (PIH) failures, risk & reward, opportunity cost in terms of time spent on your own venture vs. spent on climbing the corporate ladder and vs. traditional passive income paths say, becoming a slum lord, dividend investing etc.

I was waiting for the pitch at the end, but it didn't appear. Other than that it's a straight forward restatement of what others have said already.

The problem with these types of posts is that they make it seem like passive income is easy. In fact it is a hell of a lot of work to create, say, an info product, and marketing it can also be a full-time job. You need to have surplus income and time to take on the risk of doing this, which is hard to do if you're an employee. This probably explains why most of the passive income stuff we read on HN comes from consultants.

I've been traveling full time for the past 5-6 years ever since leaving a full time job in Silicon Valley. I've lived pretty much all over the world (now based in Eastern Europe).

I probably only make about $20-$25k a year off a few low maintenance projects, taking up random contracting gigs when I feel like.

The experience of seeing new places and meeting new people is priceless. No amount of money, equity or incentives can ever make up for that.

If I could change one thing, it would've been quitting my full time job even earlier.

But if you're interested in pursuing passive income, you probably have a different view of what constitutes wealth.

so this basically mean you gotta take the spot of the actually rich people (ie the top 0.5%) of the planet, which don't need to work.

This takes a lot of luck, in general (more than work) or/and a lot of ruse and malice.

Otherwise, if everyone just end up being a founder, it obviously doesn't work either. You need minions to do the actual work. If you don't wanna be a minion anymore, someone else has to be. Never ending loop.

This is not a PIH vs. VC funded startup issue, except that this seems to be part of an ongoing flamewar between people from both communities.

You can achieve the same balance and freedom with a part-time job, freelancing, as a PIH (although I don't think the OP actually earns passive income in the accounting sense) or some other work arrangement.

What's most important to have the kind of freedom that the OP describes is to first have a relationship with money that supports it.

MIT releases report on its actions in the Aaron Swartz case mit.edu

bguthrie 39 minutes ago 1 reply      
Those of us who believe MIT deserves some blame for subsequent events do so because they could have asked the prosecution to desist, as JSTOR did, or at least downgrade the charges to a misdemeanor, but chose not to. That amounted to an implicit endorsement of the prosecution, which would have been difficult to pursue without the support of either MIT or JSTOR.

The report appears to find that MIT should not have changed its neutral stance, which is disappointing, and I'm skeptical. Here's a quote:

    Given the lead prosecutors comments to MITs outside     counsel (see section III.C.3), MIT statements would    seemingly have had little impact, and even risk making    matters worsealthough this information was not shared    with Swartzs advocates.
It does reinforce what we already know: that the public prosecutor was mostly interested in collecting a scalp.

Keep your eyes peeled for a response soon.

denzil_correa 43 minutes ago 1 reply      
The problem with MIT's neutral stance is highlighted in the report and the one which I find particularly interesting.

    However, the report says that MITs neutrality stance did not consider     factors including that the defendant was an accomplished and well-known     contributor to Internet technology; that the law under which he was charged     is a poorly drafted and questionable criminal law as applied to modern     computing; and that the United States was pursuing an overtly aggressive     prosecution. While MITs position may have been prudent, the report says,     it did not duly take into account the wider background of policy issues     in which MIT people have traditionally been passionate leaders.
IMO, the MIT fraternity (particularly the faculty) should have been a bit more proactive in this regard.

I'm not an Android app developer, but can someone explain to me what the big deal is? I've been developing Windows desktop software, Linux desktop software and Unix server software for years. The hardware diversity on all those 3 platforms is huge. Heck, if you're developing web apps, it's like every user uses a different machine. I've never seen anybody claiming that Windows is fragmented. So what's so special about Android that people put the "fragmented" label on it, and why is that a big deal?
morsch 1 hour ago 2 replies      
I think the report could benefit from dropping the lowest 1/5/10% of devices by market share. As can readily be seen from the first diagram, Android has a long tail of obscure devices. Dropping that would make many of the other graphs more readable and more insightful. I guess it'd also be interesting to exclude devices by other characteristics, e.g. exclude all <4.0 devices because maybe you don't want to support them anyway.

I was first puzzled and am now intrigued by their choice to use physical screen size as a basis for that diagram, as opposed to screen resolution. Very appropriate in our resolution-independent times. Of course either way you do it, Android is going to have more variation than Apple. That diagram is also kind of difficult to read; what shade of blue corresponds to what market share?

Finally, it's awesome of them to share the source data! Maybe I'll actually get around to implementing my suggestions.

When personal computers were just coming into the mainstream, particularly when GPUs were just coming about, there was a similar fragmentation issue. OpenGL sought to resolve this with a crap-ton of manufacturer bits and a difficult to use API, but DirectX came along and (for the most part) solved that.

Nowadays we hardly think twice about the fact that there are millions of combinations of monitor and GPU brands and models and configurations. Has anyone ever thought to do a similar comparison of desktop and laptop "fragmentation"?

Only Apple products there - why tailor to the minority? Globally Apple has around twenty-something percent of smartphones, thirty-something percent of tablets and ten-something percent of 'PC's'. You wouldn't suspect if you looked at the media though where it often is Apple or bust. I never understood this herd mentality and I still don't. People will start dropping Android screenshots in your iProducts, Xmonad runninng on Macs (OK, that is plausible but still...), Windows will suddenly magically run on more iProducts, etc.

This is fantastic. I'm surprised I haven't seen something like this before. I think you've got a great potential market here for monetizing. It's like stock photography meets product upsell.

My first suggestion would be to get similar shots to those you've already done with a female replacing the male. It's an easy way to add more shots quickly.

I also like the idea of more scenes including people. Make it look like they're having fun and also using the phone/tablet at the same time. Smiling faces sell products!

Why You Will Never Learn to Code viniciusvacanti.com

The biggest problem with this article is that it is -- and this is non-obvious until you've read through the whole thing -- written with a very specific audience in mind. To wit, the audience the article is directed to is people similar to the author in his earlier circumstance while he was still working in finance.

It is assumes that whoever is reading the article is similarly situated to that earlier version of the author both in terms of career circumstance and interests.

This is particularly clear in this excerpt:

I found that there are two types of people that power through the frustration [...] [t]hose that are really intellectually interested in learning to code. If you havent learned to code by now, its highly unlikely youre one of them.

Doing "whatever it takes to make it work" creates profoundly different results as opposed to "learning how things work".

What a load of crap. Coding is a skill, and like nearly every skill you can learn it on the side. It's like saying that you'll never learn to play the violin unless you quit your job and force yourself to play violin for your supper. Indeed, it's even more of a silly assertion, because you can be "pretty good" at playing the violin and still not be good enough to make something out of it, but you don't even have to be that good at coding to do something useful with it.

This is almost offensively linkbait-y. In the "most popular posts" sidebar you have "Everyone at Yipit is Now Learning to Code". Why will I never learn to code? You never get to that part.

By the way, I decided to "learn to code" at age 30, and I find it interesting. Then again, I was also full of platitudes when I was in my 20s.

j4pe 11 minutes ago 0 replies      
Yes, granted, the title's intention is to inspire controversy, but it's still worth pointing out that the author's two concluding avenues to 'learning to code' - all-or-nothing desperation and irresistible intellectual attraction - are baseless. I'm confident that they're entirely false. Just more evidence-free platitudes dreamed up by a fellow twenty-something. I'd wager that these two extremes represent a very small percentage of real coders.

To answer anecdotal proof with anecdotal proof, I studied finance and taught myself to build web apps. I didn't do it because I had to. I didn't do it because I couldn't stop myself. I just forced myself to do it the same way I force myself to memorize Chinese characters, the same way I force myself out of bed every morning. Willpower isn't some mythical ability granted to the anointed few. It's just asking yourself, what am I doing right now? Is it what I want?

There's also a troubling perception of what 'coding' is behind this post and many others. I write code for a living and I'm under no illusions about my abilities. As James Somers pointed out in Aeon, I'm a kid playing around with tools given to me by adults. Nobody like myself or the author is going to build a Rails, a V8, an Ember, a Heroku. If I learned how to use a brush I wouldn't call myself an artist. It's fine that we're becoming more abstracted from the machine's reality - thank God DHH didn't have to use punchcards - but with that abstraction should come a bit of humility about what we've actually learned. Because for web development, at least, it's mostly syntax.

I'd better stop before I exceed than the original post length. If you'd like a tl;dr, it is: fuck the author's position, my experiences contradict it, and the author is confused about what 'real' code constitutes. (However, I wholeheartedly agree with his suggestion to learn by building something you yourself want.)

I didn't really start learning to code, even though I had a year of CS under my belt, until I found a problem that I wanted to solve. I was using Audiogalaxy to download music over a 56.6K modem and I wrote a program to monitor the download folder and move any file after it was completed in order to prevent automatically sharing/uploading it to other users.

It wasn't as technically difficult as most CS homework, but it was the first time I started thinking about programming as a tool to solve an actual problem I was experiencing.

The time investment is key and the OP is dead on. I can speak to trying to learn Objective-C last year on nights/weekends and not really learning the fundamentals behind I was doing, despite being able to follow along with the books I was reading and the rudimentary apps I was building. It requires a full-time commitment, which is why so many of the development "intensive" programs and workshops are time intensive (at least 8 hours per day) over anything else.

Unfortunately, the time commitment becomes prohibitive to those that have to keep running the job/consulting treadmill and can't fall back on an investment banker salary (or similar) to fund their creative ambitions for a year or more. That unfortunately is the real answer to the post's title.

All the good coders I've ever met had already taught themselves to code before the age of 10. (Most of them were so passionate about it they went on to do computer science degrees which polished their raw skills and taught them rigor.) The question isn't how to learn to code: if you have the innate ability you can't STOP yourself from coding the first time you encounter a computer. I'm all for people learning new skills later in life, but to force yourself to learn something you have no passion for just because you want to 'do a startup' is ridiculous.

A lot of people love to try and make a case for Singletons. I have yet to see anyone make a really, truly good case for a pure software singleton. They just make it an absolute nightmare to be well informed -- as a developer -- about state in complex/concurrent/distributed systems.

The only time I ever use them is when my hands are tied by some sort of hardware restriction; a JNI wrapper around some native lib that talks to proprietary hardware like a motor controller where instantiation of more than one comms object would blow out a fuse or something. And even then, I'd make the argument that the people who designed the hardware and its corresponding C API should have just made a safer interface instead of saying "Don't call `new` more than once, or else!". Seems lazy and less-than-appropriately fault tolerant.

I've always felt that the SOLID rules are very difficult to comprehend, yet pretty basic to apply. A junior dev that I recently coached, who had grown up on modern OO languages (Python, C#, etc), understood all these rules in his underbelly but would never be able to explain them.

I believe that we should be able to come up with a set of (slightly different) rules that are simpler to explain and yield the same good designs.

Always avoid singletons? Here's my situation: in various parts of my code I need to get the current time. Normally I would call System.currentTimeMillis() but in my test cases I need to ensure the time is a particular value. So I have a Clock singleton class which allows me to get the current time but also to 'stop the clock'.

Is it really better for me to pass the Clock instance all over the place, rather than have a singleton instance that can be referenced anywhere?

Leaving aside the issue of whether anyone buys into third wave feminism's definition of "privilege", this comes out as an indictment of every abuse reporting system ever made. It adds nothing and suggests nothing, only says "this sucks".

Actually, I take that back. It's impossible to leave that issue aside since you implicitly accept that definition to even make sense of this article.

Thing is, "abuse" is determined by the service provider, not the users. (And rightly so - or else you run into the problem mentioned where people flag something off and ruin someone else's day because their delicate sensibilities were offended..) Twitter and every other social communication site has a list of "thou shalt not's" which you are reporting when you click on the "flag" button.

belorn 1 hour ago 2 replies      
A very misleading title. The blog post doesn't describe an entity who copies an idea and goes to form their own company and produce competing products.

Rather, this is the simple case of a "potential businesses party" who copied front-end code, design (obviously), and images. They also redirected traffic of an associated domain. So, beyond blatantly doing copyright infringement, they are also breaking fair trade competition/fraud laws and depending on jurisdictions, trademark (established through use in the marketplace rather than registration).

What you can do to protect yourself against such activities is simple, send a cease and desist letter, file a complaint to consumer protection agency (if you've got one), and possibly send the issue to the local police.

Their suggestion of registered trademark, watermarks, and (meh) patents might increase the reward money from a law suit and increase win chances in court, but it won't actually "protect" you against entities who already willingly commits copyright infringement.

If they blatantly stole your idea - don't worry. The type of people who can't think originally enough to come up with their own idea are probably not going to execute it well either.

The same principle applies when someone else has the same idea as you at the same time, and you catch wind of it right in the middle of your implementation of that idea. It might be slightly more difficult, since you arrived at the same good idea independently of each other. Just focus on executing better.

Ideas are a dime a dozen - they aren't worth anything in and of themselves.

If they blatantly copy your code, as is the case here, then it becomes slightly worse, an actual legal issue. But again I wouldn't worry too much since I'm willing to bet that they aren't that good at coding either.

This is pretty neat, although I would suggest perhaps of limited use. The whole point of a 3D model is that it can be viewed from any angle (also at any scale). The 2D scene lacks sufficient information to reconstruct the 3D scene. This can be seen with the toys on the sofa when the back of the hippo becomes visible and there is no texture or model data. You could extrapolate and assume there's a degree of symmetry in the object, but this would only work on a limited subset of objects.

Linus's advices on git rebase and merges mail-archive.com

One of his points is that you should only pull rarely:

   And, in fact, preferably you don't pull my tree at ALL, since nothing    in my tree should be relevant to the development work _you_ do.    Sometimes you have to (in order to solve some particularly nasty    dependency issue), but it should be a very rare and special thing, and    you should think very hard about it.
That might work well for the kind of highly decoupled development he's dealing with, but I'm not sure it'll work for the kind of work I do with my colleagues. The first thing I do every morning is a git pull (often surrounded by git stash [pop] and sometimes with a --rebase appended if I have outgoing commits), because I might need the stuff a colleague worked on the past days, or we might work in the same files and generate lots of conflicts otherwise. Maybe I'm doing it wrong.

The problem with this argument is that no matter how much you make the developers aware that they are doing something wrong, there will be developers who do it when under pressure. (Meaning to go back and clean it up, but we know how that one goes.) And then when you break stuff, people OTHER than that developer will not be aware of how well you warned the developer.

In that situation, you'll be the one blamed. It is unfair, but that is what will happen.

For a case in point, Microsoft encountered this one repeatedly in the 80s and 90s. (It didn't help that sometimes it probably was their fault..but most of the time it wasn't. It really, really wasn't.)

This is quite naive.

When I learned to drive, my tester required that I demonstrate competence with the controls, using them at the appropriate times, in the appropriate ways.

If my car exposed all of its private internal operations, I would have needed to know how to use them, and demonstrated that I know that. I haven't a clue about fuel flow and gear ratios, or air/fuel mixture or how the thermostat affects how the engine operates. I'm quite happy that I didn't have to demonstrate all of that too.

What the article ignores is that a good API provides everything the consumer needs, while keeping the API small and easily comprehensible. A driver who has to keep track of 5 details is more likely to learn to use his car more quickly, and less likely to crash than one who has to keep track of 200 details and make decisions about each one.

I'm in nearly complete disagreement with the author here. I guess it helps that I've been burned more than once when using code from two third parties where party A reached into the "private areas" of party B's code. Rather than working with party B to resolve the incompleteness of the solution, they work around it and then push it to everyone. Later, when party B makes a change ("Hey, it's private, and the public interface doesn't change!") and suddenly breaks A's code - there are a bunch of un-related other parties which now have a nightmare on their hands.

Case in-point (of which there are many, I'm sure): QExtSerialPort. The author needed access to underlying Windows functionality that Qt didn't publicly provide, however, there was this nice, private header file laying around they could use. The Qt team later decided they wanted to remove the contents of that file, because no one should ever be using it. Anyone who wanted to build QExtSerialport had to go and grab the original file, and put it into the correct location. If they had instead submitted a patch to Qt to fix the problem, many hours would have been saved.

The author might get more points with me if they added "keep private usage private," but instead they are advocating accessing private internals of 3rd party tools in new open-source projects, which restricts the original developer from making changes without impacting users of the third party tools. Privacy is important - if you want to go around it fine, but you have to expect the price for you and your users, to hand-wave around that is naive at best.

Enforced privacy is advisement. It's a signal that if you want access to a library's internal behaviours or state you should either communicate your use cases to the library's maintainer or fork it and manually integrate upstream changes. This leaves the maintainer free to make changes to internal behaviours and state without breaking an implicit API contract they didn't realize they had made.

It seems that the post argues that enforced privacy is too theoretical, in practice, advice is better than enforcement.

I'd argue that the post is too theoretical, in practice, enforced privacy works much better. People will do stuff against your advice. That's OK, you say - they'll get in trouble eventually, but it was their decision. However, it affects you, the library (app, etc.) developer, as your clients might turn out to be more powerful than you.

Think of Linus' rant on not breaking userspace. He's right I believe. In general, you are not allowed to break client code, even the client did something he was discouraged to do.

Interfaces are contracts. The ultimate documentation is the code, not the comment. You are saying that in the following case,

// do not access;

Unenforced privacy is a Bad Idea for (shared) libraries that may be upgraded independently of whatever uses them. It means that any internal change becomes a breaking change, and when some application stops working after a library upgrade it is your fault regardless that you told the application developers "don't do that" (the users don't know or care that you said that, they only know that upgrading your library broke their stuff).

There's a middle ground between public and private, and some languages call it "protected".

In FOSS libraries that I maintain, methods and properties that I don't want to expose are prefixed with an underscore and designated as protected. Protected members are not directly accessible, but anyone who wishes to play with them can create a subclass to access them. They also don't need to make any further changes other than subclassing, whereas private members might need to be overridden or (even worse) reimplemented depending on the language. So I think "protected" hits a nice balance between simplicity, openness, and maintainability.

The requirement to create a subclass to access protected members might come across as an inconvenience, but it sends the same message as the article's "dodgy" JS syntax: Here be dragons, tread carefully and don't blame me if your app breaks. It would be very nice if users understood that the leading underscore is meant to send the same message, but since they're apparently not getting the message, a little more inconvenience might be needed.

The two footnotes are good counter-arguments. The only time I can imagine making a class final (can't extend) is when it's a matter of security (e.g., Java's String class).

Then there is a matter of "well, it's not MY fault if you didn't use the public API and your code is now broken." I recall even Steve Jobs chastising developers for doing this.

Building something with a sensible yet strict privacy model takes a lot of upfront design. Makes sense for code that will be used by the masses, but maybe not for a small project.

A musician needs 133,253 plays per day to earn minimum wage on Spotify theatlantic.com

Yeah, um, this assumes each stat to be the sole source of income, and to compare to minimum wage we must assume 40 hour work weeks.

Anyway, if you can't make it as a musician, I guess you have to do something else productive. Corey Doctorow gets it when he describes himself and other people who make a living in creative arts as being in the 0.001%, the extremely lucky few who get to have that as their career.

All professional musicians could disappear tomorrow and we'd still have enough great and varied music to listen to for all of anyone's lifetime and also have massive amounts of high quality participative music making by non-pros.

Incidentally, I'm a semi-pro musician myself but I long ago stopped fighting the I-deserve-a-living-as-a-musician battle and switched to figuring out how to be sure my contribution to the economy actually mattered.

I don't think the world is ready yet.. but here is my idea on how to let artists make money in a fair manner without consumers paying too much.

Imagine a clone of Spotify. You can do offline streaming and such for all the music in it. You pay $10/month for the privilege (which I think is fair). $5 or so goes to the company to maintain their servers and such. The other $5 though you can do interesting things with. Basically, each month you have $5 worth of "tip money". You can send however much money you want to whatever artist you want.. or you could alternatively setup other neat dynamic setups (the author gets 50 cents when you favorite his song, etc). .. The point being that it's under the user's control. And, if the user chose to not tip any artists this month(or they have left over tip money), then it's evenly split between all the artists they listened to for the month (depending on song count or whatever).

This model I believe would work because the biggest thing standing in the way from giving your favorite band a tip is that it's through services that you are not already using. I don't want to go to their website and then sign up for paypal to give them a $1. The thing with this method payment is already accounted for. You already paid. Now you just get to pick which band deserves your money. This could even work with a free version by doing a model like for every 10 ads you must listen to in a month, you get 10 cents added to your tip money..

If I knew anything about the music industry, this would be the startup I'd be behind. This wouldn't work with the label model, and giving artists tips isn't really something I think most people would understand at this point... but some day... some day.

Wow, I'm a little surprised. I took the _exact_ same path all the way up to PAIP. It's eerie to read your thoughts on a blog that isn't yours.

Anyway, the CLQR [1] is by far the most useful CL book I've found. It's small enough to print and bind yourself, and the pages on LOOP & the type hierarchy are just pure typography.

I recently finished Let Over Lambda (finished the first read-through, anyway), and I almost wish I had started with it. CL is the C of the lambda calculi, but it didn't 'click' until the final chapters of LoL. With a sufficiently smart compiler (and by compiler I mean sets of macros), CL can do damn near anything.

ANSI Common Lisp is a great book, too, but I found the chapters oddly arranged (chapters 12,13 need to come first, maybe).

Though will mostly repeat what others have said, here it is:

ANSI Common Lisp from Paul Graham is also a good CL textbook. I bought it as a complement to Practical Common Lisp and it also has a nice quick reference at the end.

Having read both On Lisp and Let Over Lambda, of those, I would recommend On Lisp more because it has more practical applications of macros, LOL is much more esoteric/playful/abstract, and not everybody is into that sort of thing.

One thing that troubles me about technological progress is whether we really are making anything better. Sure, we solve one problem... but it creates problems of its own, and exposes previously hidden problems.

I think this article provides something of an answer: work in itself is not a bad thing. It takes effort and concentration - it's work - but it can be enjoyable, satisfying, meaningful.

But putting in effort that is wasted, by being diverted into tedious, pointless, unnecessarily complex tasks, is a bad thing. It's not enjoyable, not satisfying, not meaningful.

Therefore, any technological progress that reduces that tedium is a good thing (even if it has problems of its own, or exposes other problems, provided net tedium is less).

[I don't think this is the whole answer, but I think it's part of an answer (probably, things like saving lives, health, and somehow enabling people to relate better are more important goals).]

> Willpower and cognitive processing draw from the same pool of resources.

Like many things in psychology, this is basically unfalsifiable. Our brains have pools of resources? How do you even differentiate between willpower and cognitive processing at a neurological level? It's one model, but there are other equally valid but also unfalsifiable explanations. What about anxiety goes up after working on a hard problem (memorizing a 7-digit number, apparently) - maybe you can test this by measuring cortisol levels - and so you choose the (stereotypically) more satisfying and rewarding dessert (cake) as a form of emotional eating and also, you know, rewarding yourself for a job well done?

I mean, it's basically just saying, "Use your brain, and your brain will get tired. Both solving problems and doing something you don't want to do count as using your brain." Sure, but I hardly need an experiment to tell me that.

Also, what about people who perform better under stress? Since it requires willpower to work hard and meet a deadline, and since the quality of your cognitive processing also goes up (for an initial period), doesn't that defeat the "competing for the same pool of resources" claim?

Psychology is great and a lot of the unfalsifiable stuff is valuable but it's irritating when it's dressed up as science.

xenophanes 8 hours ago 2 replies      
This is so stupid. The experiment can be explained in many different ways and she just picks a trendy one. Another explanation is people who did harder work were more tired and hungry, or felt more like rewarding themselves. I don't particularly favor this explanation; I have no idea what is the right explanation; and that's the point, the experiment doesn't tell us.

She also ignores that for some people it takes more willpower to eat the cake. It can go either way depending on a person's ideas. She just assumes everyone has currently trendy ideas wherein fruit bowls are unpleasant but virtuous and people use willpower to eat them. But many other lifestyles are possible. For example, one might think cake is more delicious but they are scared of getting fat so it requires willpower to enjoy eating it instead of giving in to the fear, whereas the fruit bowl is easy to eat because there's no pressure against it, so it's the easy default.

Yesterday on HN there was a link to this story:


Which had this quote:

"This isn't something that happens to some people online, it's something that happens to everyone who has ever put any of themselves out there for public consumption."

One thing that has confused me from the beginning, when Sierra first claimed that she had received death threats, was exactly why this story took on the scale that it took on. I recall at the time, of the 100 tech bloggers that I read on a regular basis, this story overshadowed everything else. I recall that previously I had been unsympathetic to Sierra because of the perception that she tended to rely on hyperbole and drama to sell her books. For that reason I was initially skeptical of her claims. Later it turned out that the 4 bloggers who harassed had clearly stepped over some line, and said some things that were at the least, very rude. As I recall, all of them later apologized (all of them were bloggers with some substantial reputations in the world of tech blogs). But given the amount of abuse that happens online on a regular basis, it seemed a little surreal to me that the story reached such a scale.

Anecdotal, conjectural, and even the dubious psychological experiments she references are completely misrepresented.

The subjects were told told to memorize a number, and on their way to a different room where they expected to be tested, someone stopped them mid-way and asked them to choose between two snacks -- a fruit salad and a cake. The people who had been told to memorize many digits didn't choose the healthy snack as frequent as the people who had been told to memorize few digits (and, presumably, could focus on which choice they really preferred).

It tries to convey "common sense" concepts, using conjecture and complicated constructs. It hurts my brain when I try to understand what is meant by "to use up cognitive resources". The more convoluted an explanation is, the less I feel it has been understood by the person explaining it. I have a strong distaste for psychology terms that add depth, but not clarity, as if trying to validate and give authority to the field or explanation.

A bit ironic for an article trying to explain the concept of "minimizing drainage of the cognitive tank" (to paraphrase).

So, what is this article really about? This -- http://www.amazon.com/Dont-Make-Me-Think-Usability/dp/032134....

My take on this, is that you can create an app/site that is engaging and depletes self/control or willpower and then monetize that at the end by selling cake or equivalent.

Can test if the conversion funnel for cake (or low self-contro) goods) sell more after a more 'intense' work out on the site/app.

Not to be too cynical but this really seems like a dangerous insight for people optimizing conversions. Hmm, everyone wants my product but it is wasteful/bad for me/a luxury/etc? Just deplete their ability to resist first. Ooops, someone trying to cancel their subscription? How about a nice maze of forms to get through first?

Anyway, the super cool insight of this article is the relationship between cognitive load and will power. We all knew "try harder" didn't work. Simplify everything else is a way more powerful way to manage your motivation and it makes it super clear that you can really only do a certain number of things. When your motivation turns to procrastination, it isn't some "problem" you are having, it is you simply hitting your cognitive limit for the day/week/month. Awesome.

Sadly, when it comes to app reviews from tech blogs and publications, the cognitive load placed on the user is rarely ever noticed or highlighted, unless it's so high that it's unbearable. Instead, apps often get bonus points for eye candy and gratuitous, but cool-looking animation. Nobody ever writes "wow, I got a bunch of things done and I didn't even notice the interface details."

This is particularly bad in the geek community, as we are used to high cognitive load (configuring X anyone?), and so we brush off any complaints about it as "stupid" or "computer illiterate."

One early app example is all the gas mileage tracking apps. Damn near every one of them in the early iPhone days had the spinning odometer control and the spinning gas number controls (where you spin each number up and down, like a key combo). I recall being infuriated by those designs, because all I really wanted to do was to quickly enter the odometer or the gallons and dealing with spinning those damn digits was NOT at all quick. Compared to the effortless/mindless act of typing into a digit keypad, spinner controls required much more cognitive load (did I spin too fast, will it go too far? Let me catch it at the right digit. Which digit do I need to push up or down to make it match what's on my real odo?).

While I agree with the thesis, a contradictory point comes to mind.

We just don't know a lot about how cognitive resources are utilized. Long distance runners know this. Athletes know this. The whole concept of "second wind". Where they find the strength to better their game using way less resources -- after they have been tired. Some type of cognitive resource depletion gives people even more energy and motivation.

While I agree that things should be made simpler and we shouldn't over-gamify things, I don't think we should make decisions with the cake / fruits question in mind. That just provides a framework to dumb things down. We will never enable the users to hit their second wind if they never get tasks that make them crave cakes.

I guess my point is: simplicity is good. Simplicity to the point of dumbness is not.

That's pretty neat. I understand why so many folks reject the claims here, but the observation itself is very interesting.

It certainly seems that highly successful, highly visible people (creatives, executives, politicians) tend, disproportionally, to exhibit behavioral problems (addiction, suicide, etc.) I don't know if it really is disproportionate, but if so, is it related to their exertion, or depletion, as the author puts is? Is it the visibility and the accompanying scrutiny? Maybe it's the other way around, and the underlying psychological makeup propels short-term performance.

Very interesting stuff, especially in context of burn-out.

Bizarre, all right. Unless the subjects were wrestlers or models, why should the choice of fruit v. cake involve self control at all? If you wished to argue that they thought they deserved more of a reward, I might be willing to consider that.

And are we talking about seven numbers vs. two numbers (as in the illustration) or seven-digit number v. two-digit numbers, as in the text?

There's one pool of resources you are drawing from but like muscular strength you aren't doomed to your current limits.

Statistically caught correlation does not imply the assusmed causation you wish to "prove".

The guys who memorize numbers might associate a cake with a reward and choose it just in order to reward oneself for a meaningless and boring waste of time they choose by mistake, while in 2 digits group it wasn't counted even as a joke.

As for willpower/self-control - hormonal levels are almost always the major factors. Just do the silly experiments which are "considered unethical" involving "images from those magazines" and you will notice lots of correlations.)

The famous experiment with tape-recorded heart-beats is the beautiful one.

Again, trying to find a single cause in psychology is kind of naive. The theoretical framework advocated by Marvin Minsky of constant competition of multitude of semi-independent agencies (specialized regions of the brain) helps to develop the notion of multiple causation.

My guess is that if one would nail a poster of a fit bikini girl to a wall, the number of cakes chosen will be reduced dramatically, everything else being equal.

But for a pony psychology the article is perfectly OK.)

Like the other commenters, so glad that Kathy is blogging again.

That being said, I am glad that she has finally verbalized what I have always felt.

As the only person running 5KMVP, I have always found that it is hard for me to do things like marketing, and customer relations/support on the same day I do development.

That would also negatively impact my performance of both.

But now that I have people working with, I can concentrate on interacting with my clients without feeling guilty (i.e. knowing that the rest of my day is dead, from a development perspective).

Also, this explains the logic behind Steve Jobs always choosing a black turtleneck, blue jeans and sneakers. If he has 1 less thing to make a decision about, his life is much easier. I have recently adopted that, and am trying to simplify my wardrobe as much as I can.

This also impacts how I schedule 'outside' events. If I have to go to an event outside of the house, that usually means no coding for me on that day. I can't quite explain why - other than the mere fact that I know I have to go out, is enough of a distraction to make me not be able to 'get into the zone'. Glad to know that I am not deficient in anyway, and it is just being depleted from the same 'cognitive tank'.

The reality is we are smart people who understand our brains, and can reprogram it. Using emotions and basic urges to create motivations and positive feelings about the things we NEED to do but typically dislike doing is the key here.

Luckily there is a group that is teaching these skills outside the normal context of "self help" that turns off oh-so many people.

I often find myself making similar justifications if I've pushed myself hard in a workout or followed my diet faithfully.

It would be interesting to see an experiment that 'cognitively taxes' participants by having them perform a task that is not considered positive. Memorizing a number elicits a feeling of accomplishment that may contribute to the justification I described above.

Not mentioned are the command line dev tools for working with the device. adb[1] is really handy on Android. You can easily upload packaged builds, stop and start apps, transfer files, invoke anything via Intents (am), get a list of installed apps, and use the shell to invoke other things (eg `pm clear` to reset an app to first user experience).

Doing the same with iOS development is painful. Apps for the simulator end up in arbitrarily named directories so you can at least inspect their sandbox and can be invoked via extremely long command lines. But forget about apps on the device itself. libimobiledevice has reverse engineered some of it, but for example there is no way to start or stop an app from the command line.

I was doing some FTUE[2] work on both Android and iOS with a third party app, and needed to stop it, clear the data and start it again. For Android I just had to press up arrow and return. For iOS I had to do multiple gestures on the device, then use an app named iFunBox (really) to manually clear out the sandbox, and then launch the app again via touch.

I don't think I've ever gotten a profile to work from the get go, even just for development(a requirement thats positively ludicrous). That's why I generally develop/test on Android first.

Seriously, I've managed to require a whole week just because of some certificate snafu.

Re: CoreData

Every iOS developer has to go through that learning curve. It is part of the initiation process, unless you want to stick with straight SQLite. CoreData becomes a merit badge of honor. Every developer has their war stories about NSPersistentStoreCoordinator, PSCs on multiple threads, threading, performance, sorting, etc.

Quick note on performance in CoreData. If you need to cache objects that you use frequently, make your own in-memory cache. CoreData is not optimized for caching objects.

But really, CoreData, is something most people who move from iOS dearly miss. Not everyone wants fine grained SQL-level control over persisting data. There is no equivalent in Android. Nada. OrmLite and some other libraries have tried. Where most of the Android OR persistence libraries break down is either m:n relationships or performance or both.

However, times may be a'changing - maybe CoreData and some of its pain can be abstracted itself - if I were to advise a new iOS developer - assuming their requirements for persistence weren't too complicated - I'd tell them to go with Parse for managing backend persistence or http://helios.io from Matt Thompson (of AFNetworking).

The thing you realize after writing a few mobile apps is that most of them are really just glorified CRUD apps. Grab something from a web service, stuff it in a table view, let the user fiddle with it, post changes to web service etc. And overall I've found writing those kinds of apps easier in Android. The framework is, for the most part, at a higher level of abstraction.

However, if you want to do something a little more interesting, particularly with any kind of interactive multimedia, then Android makes things harder or downright impossible.

The article kind of matches with my experience. And I as well enjoy working in vim more than Eclipse / Xcode. As I have significant experience with Eclipse and with VisualAge before that, Xcode took some getting used to. The coding part is ok, but for anything else (which I found out only after doing a real project in it) it is horrible. I cannot count the times I have to kill Xcode and restart it because things which were properly done just didn't work. The Stackoverflow answer to those things usually is; restart Xcode. That kind of behaviour, to me, makes it a horrible and unpredictable IDE to work with.

On a previous stable version I had to suffer a month without code completion (well broken code completion) and there were many complaints online about it, but no fix (at least none that worked for me). This did teach me to memorise more and type faster.

Also half-baked things like Storyboards & IB which you cannot really use for actual apps because you need code to add images, custom fonts etc to controls and the often buggy code generation for Coredata makes me think that this has no priority for Apple. It feels outsourced (as in, thrown over the fence with a vague spec) and more neglected with every new version, making me think it's some kind of arrogance; let developers do everything the hard way, they cannot do without us anyway. Every story and tutorial I read seems to back this up; working around the quirks in the toolchain instead of the tools helping you. I keep wanting to believe i'm doing it wrong, but I haven't met anyone yet with a better experience.

Why didn't they use SRV[1] records in DNS to resolve http2 requests? It has so many advantages:

  * Permitted at the domain apex (yes really! unlike CNAMEs!)  * Allow weighted round-robin  * Allows lower-priority fallback services  * Unusual port numbers no longer required in URIs  * Doesn't get confused with non-HTTP services located at the same FQDN.
It's the modern way to federate services! And there's very wide DNS server support - everything from BIND to Active Directory.

Fortunately the standard (nor as far as I can see, the normative references) doesn't actually say you have to use an A-type record. Unfortunately that will remain the convention unless someone makes this easy but explicit change.

I'd get involved but I fear the politics. Would I have any chance of being able to advocate for this change?

While the concept itself is hardly revolutionary this is after all how TCP itself functions bringing this capability to the widespread HTTP world will be no small improvement and may help marry the simplicity of an HTTP API with the fully-duplexed world of TCP. While this is also useful for a server-to-server internal APIs, this functionality will provide an alternative to web sockets, long polling, or simply repeated requests back to the server the traditional three ways to emulate a server pushing live data in the web world.

As far as I know, this is not true. Server Push is only for the server and can only be done as a response to a request. It's not a WebSocket alternative.

Server Push means that when a client sends a request (GET /index.html), the server can respond with responses for multiple resources (e.g. /index.html, /style.css and /app.js can be sent). This means the client doesn't have to explicitly GET those resources which saves bandwidth and latency.

I was wondering if the word "open source" is being used correctly in the context of aeroplane parts.

Dictionary.com has 2 definitions:

1. Computers. pertaining to or denoting software whose source code is available free of charge to the public to use, copy, modify, sublicense, or distribute.

2. pertaining to or denoting a product or system whose origins, formula, design, etc., are freely accessible to the public.

I guess the latter definition could apply, where the components can be produced (e.g. 3D printed) from detailed "open source" blueprints? However, I dont think the plane will be built from 100% "open source" rendered components. Generic or branded components may need to be purchased as well.

In the end you could probably build an ultralight for the cost of a pilots license.

Think about it - the most effective way to remotely cripple someone you hate is to turn the USA's ridiculous drug enforcement apparatus on them. It's not a bomb or insults, or any kind of direct or overt physical harm, it's simply mailing them a narcotic and tipping off the police.

What if this guy hadn't been monitoring things? He could very well have been in a nasty, highly stressful, possibly career ending situation simply due to America's stance on drug enforcement.

Identical Droplets in the DigitalOcean: Regenerate your Ubuntu SSH Host Keys now missingm.co

agwa 14 hours ago 6 replies      
SSH host keys are problematic on cloud servers, not just because of this problem, but also because if the cloud provider does the right thing and generates the SSH host key on the first boot, the key is generated when the system has very little entropy available. The primary sources of entropy on Linux are key/mouse input, disk latency, and network interrupts. There's obviously no keyboard/mouse on a server, and in an SSD environment like DigitalOcean, disk latency is quite uniform and thus useless as a source of entropy.

Linux distros mitigate the cold boot entropy problem by saving some state from the RNG on shutdown (on Debian, it's saved in /var/lib/urandom/random-seed) and using it to seed the RNG on the next boot. On physical servers this obviously isn't available on the first boot, and on cloud servers, the provider often bakes the same random-seed file into all their images, so everyone gets the same seed on first boot (fortunately this doesn't harm security any more than having no random-seed file at all, but it doesn't help either). What cloud providers should really do is generate (from a good source of randomness) a distinct random-seed file for every server that's created, but I haven't seen any providers do this.

This is not the last of the problems we'll have with "the cloud", but I guess it's part of what makes it so exciting. :-)

Many people, especially beginners, make the mistake of leaving the same SSH keys in a certain template or in a snapshot of a virtual machine that they later use as a template.

There are a few files that you really, really need to wipe out from a wannabe image template:

- /etc/ssh/* key* (for reasons explained in the parent article. stupid autoformatting, remove the space after the first asterisk)

- /var/lib/random-seed (the seed used to initialise the random number generator. this is the location on CentOS)

- /etc/udev/rules.d/70-persistent-net.rules (so that the VM's new NIC - with a new MAC - can use the same "eth0" name)

People who want to do this more exhaustively can have a look at libguestfs and it's program virt-sysprep which does all of the above and more!


rwmj 10 hours ago 0 replies      
They should be using cloud-init or virt-sysprep[1] on new instances. In particular, it is vital that you give your new instances a unique random seed (which virt-sysprep can do). Also that you provide the virtio-rng to guests that support it.

To avoid this kind of security problem, use providers that use official Ubuntu Cloud images only. If Canonical haven't certified the Ubuntu images you're using, then your provider could have done anything to them. You'll need some other way to determine their competence.

Cowboy images like this are exactly the reason trademarks exist. Commercial providers who don't get certification are in fact violating Ubuntu's trademark by telling you that you are getting Ubuntu, when in fact you are getting a modified image which is possibly compromised (such as in this case).

Generating fresh keys aside, one thing I do with our AWS setup is whitelist the IPs that can connect to our SSH bastion host. This completely eliminates scripted port scans of the SSH server and makes the auth logs much more manageable.

If our IP address changes (eg. ISP assigns a new one for the cable modem) then we just update the whitelist (and remove the old address). It's very infrequent. I could probably count the number of times I've done it on one hand.

It might not be the most scalable setup but at our small size with everybody working from home it works great.

The only slight hitch is updating it when traveling but even that isn't much of a problem. It takes a minute or two from the AWS console and its good to go.

I recently took a look at digital ocean ($5 servers gives me ideas...) but didn't see a firewall option similar to the security group setup in AWS. If it does exist then I highly recommend it.

One good thing to note is that any VM image using cloud-init (a package for debian/rhel systems) should automagically generate a new host_key set for any new system image.

If there ever was an article written and filled with mis-information and a completely superficial look at the pros and cons of the Danish society and it's merits, it is this article.

The claim that Danes are ambitious is flat out wrong. The younger generation more so, but there is a reason why danes are the "happiest people" in the world and it's not because of their ambitions.

The Danish model is under huge pressure and haven't escaped the reality of globalisation and automatisation.

But because wealth gets distributed the way it does, it doesn't feel the heat too much just yet.

In other words the Danish system is a thing of beauty as long as it works. Unfortunately it doesn't work anymore and somethings gotta give.

Edit: Was asked to be more specific.

Out of 6m people:

Almost 0.8m people on some sort of social welfare

Almost 0.8m people are working in full time positions for the public sector.

In comparison 1,9 in the private sector and it is shrinking rapidly.

It is notoriously easy to start a company in Denmark but notoriously hard to grow it among other things because most Danes don't have those ambitions and are very very risk-averse.

We are long past the point where more people are depending on the state than on the private job market and as those jobs disappear because of the named automation and globalisation and because Denmark is just too expensive, it will be hard for any government to promise the elaborate system we have now.

This is already starting to show as the latest government scramble to lower taxes for corporations and reduce the number of entitled benefits Danes can expect.

Furthermore Denmark took the wrong educational strategy and unfortunately like most of the european countries believed that knowledge worker meant book reader.

The result of this is that we have a large over educated part of the population who will have a very hard time finding a job.

ForrestN 1 hour ago 0 replies      
"Ambition" is probably a less useful frame, in the article and in the comments, than "expectations."

I've only been to Denmark a few times but I think the feeling I got is that they are happier because they have managed to largely sidestep the otherwise ubiquitous trap of perpetually escalating expectations.

The American/capitalist model is that each achieved goal is a platform for the next goal. Growth is what matters. Being satisfied with a decent job and a peaceful context in which to love your family is not any less ambitious than desiring to get rich or "change the world." It's just ambitious in a different direction.

Americans, for example, optimize for economic performance. Danes, I think, optimize for happiness. The tantalizing, troublesome idea that captivates me as an American is that money as an abstraction of 'value,' when survival is assumed, might only be desirable as a tool for being happier.

And if the pursuit of money, on a societal level, interrupts the pursuit of happiness, that implies that we capitalists are doing it wrong.

4. You pay 180% (one hundred and eighty) of taxes on top of the value of a new car (180%...) when you buy it

5. The cost of living is high, very high

6. Foreigners, if they are not from US, are not very welcomed (say what you want on this, it's been my and others impression). Compare this with, say, Germany, and you see a big problem right there

7. There is not really much good work. I get it, 5-6 mln people, but finding a work in Denmark without Danish is like finding the eldorado

Overall, I would not take this country as a "model". If you want a model, take Germany. Germany managed to get out total destruction (world war II) and the whole West/East mess without asking help to anybody. Germany today is probably one of the most open countries to foreigners. The Police in Germany is great with everybody (I had my bad experiences with the Danish one doing absolutely nothing wrong...).

Sometimes you need to look deeper to see what's really going on in a country. "Working hours" should not be the only way we measure things.
