Ask HN: Opposite of not invented here?

I am familiar with the idea (and have felt it in the past), but the best approach I have found for most places (less than 10k engineers on staff) is, "be very careful that you only invent things that are core to your needs."

The greater internet population will move faster than your internal team, and your beautiful snowflake will be supplanted with a better OSS option much more quickly than you expect if it is not a core driver of what you are doing. Your time and attention will necessarily shift to the core once the non-core is good enough. Therefore, you are almost always better off contributing to something external for non-core software rather than reinventing internally.

So, if it is core to what you do then build it yourself and maintain (possibly shared) control of it. If it is core to what you do but is not differentiating, open source it and drive to create a real community around it (so that it is the thing that keeps getting better, and you already use it!) If it is core and differentiating, then you are talking product strategy and there is no pat answer :-)

(edit, minor grammar fix)

> I am not keen to maintain code and have to answer questions from every Tom, Dick and Harry

This seems like the wrong attitude. Software development is about writing and maintaining code. If you need to solve a problem that is not cleanly solved by an existing library, it's your job to write the code, maintain it, and help your co-workers use it.

Remember, the people who wrote those open-source libraries are humans like you. They had enough confidence and experience to feel comfortable releasing their work to the world, but they are not super-geniuses. You can confirm this by looking at the source code of a typical open-source library :).

Personally, I prefer to avoid third-party libraries that impose a lot of structure on my code. My ideal third-party library is one that implements a single, complicated function (or family of functions), like solving a linear system of equations. In these cases using the library is an obvious choice. In cases where the library (framework) forces you to change the architecture of your application, you should think deeply about whether or not it's worth it.

I guess the overall message is: take ownership of your work.

In large enterprises you see the opposite of NIH. There isn't a name for it but it's something to the tune of "You never get fired for choosing IBM."

I remember constantly fighting for the right to develop the important software in-house rather than trying to cram them into a Salesforce app or buy some [x]-as-a-Service that does 60% of what you need and gives you 0% competitive advantage or intellectual property.

There's reasons for both approaches but you should never be too far in either direction.

As pointed out in another comment, analysis paralysis is the term you're looking for here. One strategy to get past it is to timebox the analysis phase. For instance, give yourself two days (or however long is reasonable) to spend on research, but no more. At the end of the two days your should either have a clear answer or you will have run out of time and need to make a decision based on imperfect information. Realize that information is always imperfect and most times the options won't impact the end result in very different ways (otherwise the answer would've been clear), so there's a lot of benefit to just getting started. Decisions can be reversed as well, so nothing is final.

The opposite of NIH is Tinker Toy. You just glue existing bits together. This can work, but usually only on problems that have been solved before, and therefore have OSS software available.

A good example I experienced personally is data pipeline / job management. Six years ago there wasn't much out there, and at Facebook they developed DataSwarm. Today there are many decent OSS choices out there, including AirBnB's Airflow, Oozie, and Apache NiFi which was developed by the NSA.

"premature optimization is the root of all evil"

I think you're conflating NIH with "willing to write code that isn't absolutely perfect."

I think your paralysis is coming from perfectionism.

We all want to build the Eiffel Tower and Mars rovers, things meant to be temporary but end up being elegant and lasting for much longer than ever intended.

None of us want to build things like the Tacoma Bridge, things with inherit flaws that are disasters.

But in the end, remember, most of what we build are really just kitchen tables and midrange houses. We should take pride in our work and do our due-diligence, but in the end, we have to ship code.

Do the best you can today. If someone has an issue with the result, either they'll fix it or you'll have the opportunity to fix it yourself.

Live with the shortcomings until you see a demonstrated need to fix them. Usually by that point, you'll have a better idea of how to get around it as well. You'll avoid doing extra work early.

Ask HN: Team for Hire?

As another Chattanooga dev, I hate to be a wet blanket, but I would be very surprised if any startup here has a need for or ability to employ a team that large. Especially since the larger employers here (TVA, Blue Cross, Unum, Covenant Transport, USX) are all .Net shops.

I'm not saying it's impossible, just that I believe you would be better served to either find individual jobs here, or be willing to relocate. (And just to be clear, I'm not pushing the relocation thing. I love this city and wouldn't want to move either.)

MailChimp?

Just the other day HN had an article on them. They are in Atlanta, so not far from you.

They are looking to hire 150 new employees within the next year.

>> "[MailChimp] now employs about 550 people, and by next year it will be close to 700"

https://news.ycombinator.com/item?id=12642824

Since OpenTable sends email confirmation for restaurant reservations, your team might bring interesting insight for MailChimp since it's possible you might be a current customer of them.

If you can't find a group that will hire you as a team, perhaps you should start a consulting / product firm. There's overhead / non-dev work to setting up shop and starting a business development pipeline to get revenue in the door of course, but if you want to stick together, build great things, and keep your culture that's a solid option if others fail.

Sorry to hear that OpenTable's moving out of Chattanooga.

I was in Chattanooga from 2013-15 and have nothing but good things to say about their team. Most notably they ran a functional programming meetup that covered pretty advanced topics but was still inclusive to beginners. I'll remember the encouragement I got there for a long time.

If anybody who cares about the Chattanooga tech scene reads this: do your best to keep the OpenTable team intact. A lot of the programming community's enthusiasm is either directly coming from or being encouraged by them.

DISCLAIMER?: I was in Chattanooga a couple weeks ago and they gave me a bunch of useful, free advice on my current project. This isn't really a disclaimer though because IMO it just reflects even better on them.

Interesting. I know there are Very good reasons for not relocating to either Los Angeles or San Francisco, but what were the specific reasons (aside from family/homes, if any) you and the team had for opting not to relocate?

Further to this:

2) Were team members offered raises as part of a relocation package?

3) Were team members offered the opportunity to work 100% remotely?

4) Has OpenTable approved this message?

5) Regardless of #4, are there certain conditions others would need to be aware of such as non-competes? I know NCAs are fairly (if not entirely) powerless in California, but I'm not aware of the laws impacting them in Tennessee.

Edit: per user @rfc's jogging of my brain, Stripe has a program for hiring full development teams. @wilwade, this might be worth applying to. I know I posted it in another comment, but it's worthy of top-order visibility: https://stripe.com/blog/bring-your-own-team

Chattanooga is a beautiful town. I almost moved their in January. The city has a lot to offer and it could be one of the next great tech hubs.

I decided not to move because I didn't think the local economy offers a lot of choice for software engineering jobs. When I visited people remarked, we've got VaynerMedia, we've got OpenTable, we've got CarbonFive, etc. etc.

This news sucks because I really want to see Chattanooga grow into a techhub, but it also confirms the suspicions I originally had. :/

You'll find success faster if you split up and join the talent pool sooner rather than later.

If you're trying to get hired as a team, that sounds new, so employers might not have heard of such a thing.

It's the first time I've heard of something so preposterous. Maybe if it was a progressive state like Colorado, I could understand, but Tennessee? I can't stand the hot, humid summers myself. Then you have chiggers and scorpions to worry about. ;)

Compliance with local currency regulations is probably a hard problem, not just because the regulations may be written in the local language but because their interpretation may vary with time, place and the individual interpreting...and the amount of money involved.

Then again, it's money so it's worth taking seriously and paying for or developing expertise for any project that matters.

shadowwolf007 5 hours ago 0 replies      
The standard rounding for financial applications is typically Banker's Rounding, which is another way of describing rounding to the nearest even. E.g. 1.5 rounds up to 2 but 6.5 rounds down to 6. Over the long haul, this method of rounding produces the least amount of error. Some regulations and laws, though, specify different rounding techniques or specific phases in a process where rounding must or must not be performed. Especially critical in things like forex and other trading type applications. In addition to what byoung2 mentioned, Canadian law has specific rounding regulations that change based on what payment method is being used, but (as far as I know) don't generally apply to things like interest calculations and stuff like that[1].

ISO 4217 works well for display purposes but doesn't work for all financial applications. Consider, for example, scenarios involving tax or a product billed based on usage. By rounding off at each processing step, the company could be losing substantial amounts of money. The last two companies I've worked have used varying types of mechanisms for tracking fractions of pennies. In some circumstances, it makes sense to store everything as integers with a separate column to represent precision, but I would probably not do this unless you have a specific use. It's a lot of noise and mucks up the source code worse than, say, a BigDecimal or Decimal type. At the current job, we store everything with 6 digits of precision because of the nature of our billing and use Decimal as a reserved type for only money.

To be honest, if you have an accounting department you probably want to involve them in these discussions because rounding decisions can have impact on your financial statements and, potentially, any audits that may occur in the future. I've worked on two financially focused applications so far and I would strongly suggest that you build out a very defined and clear way to manipulate money for rounding purposes. Building out those processes in a standardized and well-defined way makes for easy unit tests and also helps those who come in the future understand the decisions made.

byoung2 12 hours ago 1 reply      
A quick search reveals that the highest precision should be used for storage and calculations, and rounding just for presentation. So it shouldn't matter what rounding rule you use for display purposes.

Linus Torvalds on Git. It's funny, and it really does tell you a lot about why Git is the way it is.

Bryan Cantrill's 2011(?) Lightning talk on ta(1). It's fascinating, but it also shows you just long-lived software can be.

Randall Munroe's Talk on the JoCo cruise. Because it's effing hilarious, and teaches everybody the important art of building a ball pit inside your house.

Finally, an honorable mention to three papers that don't qualify, but which I think you should read anyway.

Reflections on Trusting Trust: This is required reading for... Everybody. It describes a particularly insidious hack, and discusses its ramifications for security.

In the Beginning Was The Command Line: If you want get into interface design, programming, or ever work with computers, this is required. It's a snapshot of the 90's, a discussion of operating systems, corporations, and society as we know it. But more importantly, it's a crash course in abstractions. Before you can contribute to the infinite stack of turtles we programmers work with, you should probably understand why it's there, and what it is.

Finally, The Lambda Papers. If you've ever wondered how abstractions work, and how they're modeled... This won't really tell you, not totally, but they'll give you something cool to think about, and give you the start of an answer.

"Writing A Thumb Drive From Scratch" by Travis Goodspeed - https://www.youtube.com/watch?v=D8Im0_KUEf8&nohtml5=False

Excellent talk on the hardware side of security, goes into some really cool theoretical hard disk defense stuff, incredibly insightful and introduces a hardware security tech toy so fun you'll want to go out and order it the moment you're done watching. The speaker is entertaining as all heck to boot.

"Programming and Scaling" by Alan Kay - https://www.youtube.com/watch?v=YyIQKBzIuBY&nohtml5=False

Interesting talk on the theoretical limits of code size and engineering versus tinkering. Also talks a lot about Alan Kay's philosophy of computer science which analogizes systems to biological systems, which are the systems with the largest proven scaling on the planet.

"The Mother Of All Demos" by Douglas Engelbart - https://archive.org/details/XD300-23_68HighlightsAResearchCn...

This talk is so prescient you won't believe your eyes. Given in 1968, Douglas demonstrates just about every major computing concept in use today on a modern machine, along with some ones that are still experimental or unevenly distributed such as smooth remote desktop and collaborative editing.

"The Birth and Death of Javascript" by Gary Bernhardt (probably the most talented speaker on tech) at https://www.destroyallsoftware.com/talks/the-birth-and-death...

I'd mention Bret Victor's work before (maybe Drawing Dynamic Visualizations?), but Bret cheats by writing a lot of amazing code for each of his talks, and most of the awesome comes from the code, not his (great nonetheless) ability as a speaker.

Then you have John Carmack's QuakeCon keynotes, which are just hours and hours of him talking about things that interest him in random order, and it still beats most well prepared talks because of how good he is at what he does. HN will probably like best the one where he talks about his experiments in VR, a bit before he joined Oculus (stuff like when he tried shining a laser into his eyes to project an image, against the recommendations of... well, everyone): https://www.youtube.com/watch?v=wt-iVFxgFWk

First, the "Mother of all Demos" by Doug Engelbart: https://youtu.be/yJDv-zdhzMYThis was in 1968, at a time when most people thought about computers as being machines for solving computation problems, like processing payrolls or calculating rocket trajectories. Engelbart and his students had the radical idea that computers could be used for human "knowledge worker" productivity. In one 90 minute presentation, he introduces everything from the idea of a GUI, to the mouse, to word processing, hypertext, computer graphics, and (simulated) videoconferencing. You have to be able to put yourself in the shoes of the audience that has never seen this stuff before, and it'll blow you away.

Something more recent:Martin Fowler's great introduction to NoSQL: https://youtu.be/qI_g07C_Q5INot so technical, this is a great overview of the reasons why (and when) NoSQL is valuable. He crams a lot into a short speech, so it's one of the rare videos I've required students in my database classes to watch.

Now, really getting away from the technical, I have to recommend watching the IDEO shopping cart video: https://youtu.be/taJOV-YCieIThis is the classic introduction of Design Thinking to the world, in 1999. If you're using the Lean Startup or an Agile method, but have never heard of IDEO's shopping cart, you may be able to get along fine at work, but you should be kind of embarrassed like a physicist who's never read Newton.

CppCon 2014: Mike Acton "Data-Oriented Design and C++"

https://www.youtube.com/watch?v=rX0ItVEVjHc

Detailed discussion of how to get the most out of your memory cache and memory bandwidth, focusing on games development. It's full of examples of how understanding both the problem and the hardware, and working in a straightforward way, can give you huge performance gains over using poorly suited abstractions. It shows how low level thinking is still important even with modern compilers. I recommend people interested in performance optimization watch it.

Gary McGraw: Cyber War, Cyber Peace, Stones, and Glass Houses https://www.youtube.com/watch?v=LCULzMa7iqs

I like how this talk cuts through a lot of the BS in security. One of his points is that the US and other rich Western countries have a lot more to lose from a possible "cyber war" than our potential adversaries do.

Another key point is that we'll never make much progress unless we can somehow start building better systems in the first place, with fewer vulnerabilities for an adversary to exploit.

I think the second point has become a lot more widely accepted in recent years since McGraw started giving this talk. Unfortunately it sounds like a lot of government folks still haven't got the memo on point #1.

Ashton Kutcher--Startup School

I like it because it is the intersection of so many things. He starts slow, is very intimidated by the audience. The audience, obviously super skeptical of the clown from that 70s show giving any useful information, they could learn from. He finds his footing with a great morivational story (albeit laden with a few cliches) about a forgotten entrepreneur and how he built some lasting value.

For me, this is a great talk. The story is extremely motivational and has some interesting bits of history & entrepreneurial genius-- but the entire experience is extremely educational. About bias, drive & success.

I liked it for what it wasnt.

Well. There's enough quality content in this thread to start a dedicated cable television channel, a la Viceland ;)

Not sure if it's my favorite. And the subject is more technology than "tech". But the talk that keeps haunting me is Michael Dearing's lecture from the Reid Hoffman "Blitzscaling" class at Stanford:

Heroes of Capitalism From Beyond The Grave

https://www.youtube.com/watch?v=3vCdfa_aeI8

Dearing draws upon an obscure letter by Daniel McCallum, superintendant of the New York and Erie Railroad, written to his bosses in the 1850s. In the report, McCallum bemoans the stress and frustration of operating a railroad system spanning thousands of miles. All of the joy and magic he used to revel in whilst running a fifty mile stretch back in his home town has long since dissipated. Furthermore, the unit cost per mile seems to be exploding rather counter-intuitively!

Dearing goes on to elucidate the absolute necessity of the railroads ("the thing to know about the railroads is: they were startups once") themselves. As guarantors of civilization and progress. Beacons bringing light and reason to the dark swamps of ignorance and inhumanity. And not just in the physical transport of goods, people and ideas across the continent. But as the wealth created from that creative destruction remains the best cure for all of our other inimical maladies: poverty, injustice, disease and stagnation.

So, no pressure. But civilization depends upon you!

I think art is art for its own sake, if you have a tool and decorate it, that would be a combination of a functional tool and art. Mathematics and derivatives in particular have enormous practical value yet many aspects of mathematics is pure art. Logic as art would be music, logical scales of sounds is definable an art. I have lost the thread of what I was saying so will leave my comment unpolished as performance art :)

I personally love the work of C-C Shan.

Read "From word to sentence. A computational algebraic approach to grammar" by J. Lambek. Your university library should have a copy, if not press the issue to your librarian.

Start though with Smullyan's "To mock a mockingbird".

These suggestions reflect my taste. Art is a language, so understand how language is studied and use it to approach art.

If you're serious about the art part, make sure you make art, or at least dissect art you like using the formal tools you're introduced to.

Have fun!

I tell students that it would be good to have a "problem solving" major (such as engineering, computer science, business, or law) as well as a second major in a "problem" they care about, which could be anything from art to zoology. Then you have the ingredients for a career -- applying your problem solving methodology to a problem you know something about.

In your case, maybe you learn computer science and you apply it to some problem in art or the humanities.

Best method to cancel human voices at work or public space?

kafkaesq 23 hours ago 1 reply      
Ultimately, technology is limited. What you need is a culture of "library voices". To wit: "Don't raise your voice unless you absolutely have to. Better, don't use your voice, period, if you can just do a chat session with the person. If you must use your voice -- just keep the volume down, and and the duration minimal. If you must have a full-volume conversation for any length of time -- get a room."

Basically, people in office environments get used to "yapping" for a whole lot of reasons not related to any actual need to exchange information (to vent and shoot the shit, basically) and to do so in rollicking, loud "party" voices without any regard to the downsides. Meanwhile, all it takes is a bit of introspection to realize that about 80% of this noise is just that. And a little bit of discipline to institute a culture of (relative) quiet and solitude -- even in an open plan office.

What, you say -- no time for introspection? No interest in discipline? No way to even bring up the idea of "library voices" in your culture?

Then your problems are much bigger than can what be helped by any advanced technology.

For me it is the sharp spikes in sound curve that is annoying and distracting, like honking of vehicles, screaming kids etc in an otherwise quieter environment. Any uniform/sustained sound, for that matter even constant blaring of horns on busy roads or bunch of noisy kids playing, will quickly melt into the background. I suppose this is what happens to most people too. So I just have to tolerate a bit for the easing up to happen. Earplug like contraptions make me claustrophobic of sorts. Also, I like to do things "naturally" and condition myself in general, so this approach might be due to that as well.

I've had great success over the last 10 years with a pair of Sennheiser 280 HD Pro over-the-ear headphones (https://en-us.sennheiser.com/hd-280-pro). They are great at passive noise attenuation across the spectrum (32 dB) and are extremely comfortable for long periods. It doesn't hurt that they sound great (if you like a flat frequency response) and since they are made for pro DJ and studio use, they're durable and the cord, ear pads, and headband pad are replaceable.

If I don't want the distraction of music, but still need to wipe out the sound of people talking nearby, I fire up https://rain.simplynoise.com/.

Whatever you do, don't go for an office that has a "noise suppression" system in it. A company that I used to work for has one, when I first joined I thought it was just a loud HVAC system (until I was informed what it really was). It took a lot of getting used to, or so I thought, then the headaches started coming. Headaches that would start at work and then dissipate an hour or two after leaving the office. After doing some reading and discussing with a relative who designs buildings for healthcare, I realized the connection between the two. I started working from home, no headaches. Apparently a not insignificant percentage of people have this reaction to a constant "barely audible" white noise. I'm not sure if I would have the same reaction to the headphones, but at this point I'm not trying it.

Voices, especially high ones, are kryptonite for NC, but the very latest models do better with them than I've ever heard before. My Bose QC35s and QC20s both do a great job of making a voice six feet away sound at least 20 feet away, and voices over 10-15 feet away not sound at all. I think the QC25s and QC30s will be similarly good. The new Sony MDR-1000X are also supposedly showing next-gen NC performance, according to early reviews.

A set of one of those will probably do the job of lessening voices to something acceptable--they do to the point that my very, very distractable self can work in an open office, whereas older NC headphones did not--but they won't completely remove it.

If you really want that, I'd suggest a set of 34dB+ reduction earplugs. If that doesn't work, put them underneath NC over-ear headphones. If that doesn't work, play white noise on the headphones. I'll be surprised if you heard anything external after that.

A few folks have mentioned white noise already. I used to work in an open-office layout with about 50 people, and I found it was much easier to mentally cancel out the chatter with consistent, light, inoffensive background noise than to try to create silence.

http://mynoise.net was great, and I only had a $10 pair of in-ear earbuds. I haven't used the site since changing jobs, but I remember liking Rain On A Tent, Wooden Chimes, and mumbly-voice environments like Laundromat and Airport Terminal.

The best $50 I've ever spent has been on a pair of Audio-Technica ATH-ANC2 noise cancelling earbuds. Are they as good as Bose or other over-ear versions? No, but they are significantly better than non noise canceling and pretty cheap. Paired with a white noise generator (I use Spotify that has many), and the loud coffee shop chatter fades away and I can get work done.

I might be completely wrong but I think if you request from a position of strength, in that you have pleased all the interviewers and they are visibly eager to hire you ASAP, then it seems possible that they let you have a look, if not the core logic at least the less critical parts. Whether or not it is rude depends on how you make the request. :)

About horrendous code, I haven't changed many companies so I wonder how many real world products that are some years old have code bases that are not some sort of a hard to figure patchy clutter if not down right trainwreck.

As for employees looking at my code, it isn't as straight forward. The code I upload to public repos like github are meant to be seen, used, extended and/or appreciated by peers, so letting potential employers look at them isn't a problem. However, when I mention that I have some personal projects brewing, which to me are potential business ideas, I would not let them in on too much detail much less look at the source code. Even if then agree to sign an NDA I wouldn't let them as I don't trust big corporations.

I think if you can answer the questions above, you can find the right questions to ask. Then you can start to ask the right questions. Can you see my code before I hire you? No.

Absolutely! I always ask to see the code, and have turned down jobs before because I can see the system is a total train wreck.

I dont expect perfection, and indeed perfection doesn't exist. I also believe that done is better than perfect.

But I have seen some royal clusterfks in my time, and I think it's perfectly reasonable to ask to see the code.

I'm not sure that it's rude, per-se. But, it would be considered a disclosure of sensitive IP. (Obviously, most corporate codebases deserve to be gutted and rewritten from scratch, but there's some kind of internal valuation.)

For some perspective -- the company I work for was sold for a tidy sum, and part of the negotiation was that the buyers got statistics about the codebase (number of lines of code, which languages certain sections were in). They didn't get to see any of the code before the sale closed. And, a prospective buyer has a lot more to lose & a lot more influence than a prospective employee.

Great question. Employers sure don't have any reservations about seeing your GitHub, watching you whiteboard random and obscure puzzles for 8 hours, requesting 50% of your yearly time-off on worthless interviews, etc.

Seems like what's good for the goose and all...

Having thought about it, I'd probably run as fast as I could if an employer with whom I was interviewing had a over-grown, out-of-contgrol spaghetti-code, all-javascript-SPA type code base - all business logic on the front-end, endless chains of promises and events being fired asynchronously from God-knows-which controllers, etc.

Add Mongo or another NoSQL solution as their main backend, and the interview would come to a hasty end. :)

And let's be honest, unless the potential employer is working on Top Secret defense software or is some Silicon Valley, PHD-heavy AI startup, their typical CRUD app does not warrant a NDA or anything else, at least for a cursory glance at the main code base, build system, etc., especially if you're not currently employed with their direct competitor(s).

Take advantage of this to call a number of accountants and ask them these questions -- you'll get answers quickly

It's actually a combination of public knowledge and trade secrets. The public knowledge comes from what the chip-makers themselves describe in conferences, trade journals, etc. Those would get you really far in design, implementation, and verification. There are also trade secrets for optimizing both digital and analog components. They stay trade secrets for the obvious reason of slowing competition but also to reduce odds of patent suits given about everything you can think of will get patented in this field. Especially micro-architecture tricks within CPU's.

You can get much of the knowledge you need from books, CPU specs, academic papers, open-source CPU's in industry, and so on. The standard cell model is the easiest with the highest performers being full-custom designs. There are plenty of successful designs in former with good performance, though. So, that's you're best bet.

Here's a GPL one used in embedded (esp space) applications for you to start with that has good performance and extremely-high configurability:

http://www.gaisler.com/index.php/products/processors/leon3

Recent one for open ISA:

https://github.com/ucb-bar/rocket

Lots of interesting things might be done with asynchronous logic that's not as explored and patented compared to synchronous techniques. The cutting-edge stuff is using it more and more. Whole chips have been done that way that were easier to fab right the first time plus with energy and performance benefits.

Ask HN: Self Driving Car Engineer Nanodegree

Hi all,

My name is Dhruv (dhruv@udacity.com) and I lead the Self-Driving Car Nanodegree program here at Udacity. I'm happy to answer questions directly on this note (email me!). I think this program will be very different from our existing Nanodegrees as we have real industry partners who are extremely invested in making sure the program is high quality from the get go. This is because they want to be able to increase their hiring pipelines as soon as possible. We've been determining what projects/content to create by asking our hiring partners (and Sebastian Thrun) what they would want to see in a portfolio of someone they hire. We then work back from there and iterate to create the content. So far, folks at Mercedes-Benz, Otto, NVIDIA, and a few other auto companies have gone over our syllabus, given us feedback, and helped us iterate. I'm trying my hardest to make this program something I would myself take to get into the field or learn more about it(I'm an Engineer by trade who moved into this role!).

Can anyone who works for a top SDC company (comma.ai, Zoox, Cruise, Uber/Otto, Tesla) comment whether they would consider an application from someone with a technical qualification plus this "nanodegree"? Throwaways acceptable, looking for a pragmatic insight from an industry insider.

There is a lot of PR speak clouding my judgement.

I think the SDCND is a great opportunity to get hands on experience with cutting edge technologies. You will be evaluated and receive personalized feedback on about 15 practical assignments covering these topics:

Computer vision (Detect lane lines in a variety of conditions, including changing road surfaces, curved roads, and variable lighting), Neural networks (classify traffic signs, drive a car in a simulator), Track vehicles in camera images using image classifiers such as SVMs, decision trees, HOG, and DNNs.

More projects will cover these topics: Sensor Fusion, Localization, Control, Path Planning, Systems and an Elective.

If you know of comparable ressource to gain experience with all this material please share, I'm not aware of any.

They're very light. Since they don't carry any weight you'd at least hope to learn something.You'll get as much if not more from the free machine learning Georgia tech course with Tom Mitchell's book than the nanodegree.As a follow up, I took Thruns robotic driving course and it suffers from being a purely software course. There are optional hardware projects but no imparted hardware instruction.So I'd be especially leery of an automated driving nanodegree degree online.

Seems like a good way to break into the field. I was accepted too and looked through the released syllabus after digging around a bit -- they do a good job integrating computer vision, sensor fusion, and path planning. They have some cool perks like being able to run your code on a car and running driving simulations. I don't think it will get you to a job by any means -- at most an internship. It does seem like a good foundation to have for jumping into more advanced topics though.

I was accepted. I am most interested in spending a long time (9 months) learning about autonomous systems. I also like that a single autonomous system, a self-driving car, is the focus. I think this will be more valuable for my learning style than a more academic machine learning course which might tackle many applications, which are probably already mature solutions. I like that self-driving cars are a newer application and the course might actually push the state of the art.

As a more esoteric bonus I'm evaluating this kind of learning as a potential replacement for higher education for any children I might have, given ever-increasing costs for brick-and-mortar universities.

It is clear that the application paradigm is broken and that people hate apps (even though they think they like them). A unified interface will soon replace it.

Most people seem to think that the main interface with this so-called AI will be text/speech. This is incorrect. Interaction with AI will be spatial (think HoloLens), graph-oriented (think Semantic Web), and binary (think Tinder).

The big idea, which most people don't seem to appreciate yet, is that all apps are basically the same. Tweaking the layout and renaming "share" to "retweet" doesn't change the semantics of the underlying interaction. The next big thing will be some kind of app/service/protocol la WeChat that let users accomplish 80% of what all other apps combined offered. Yes it will kill branding, yes there will be a learning curve. I suspect that those who will succeed will make kids their target demographic.

What about Cyc?

https://en.wikipedia.org/wiki/Cyc

I think it could work, and best if paired with an application project. Not everything is scalable and a long, hard march may be required to create some kinds of systems, especially with respect to Agent based computing.

Personally I think Agent based computation is the next big thing after Social, but it is hard to tell what form it may take. I am far from convinced that Apple or Google have the chops to do what is necessary, because it would surely require them to violate their own interests and probably legal obligations.

Talking of that sort of thing, you should look into Urbit.

Urbit is a network computer that could hypothetically allow Agent based computation to actually work.

Urbit is definitely fringe science stuff, I'm sure Walter would approve.

Honestly I would look toward manufacturing, particularly if you can incorporate ideas from the world of the digital -- for example crowdsourcing, mass customization, or continuous delivery of updates/modifications. I read an article in WIRED oh, I guess about five years ago now, called "Atoms are the new Bits" that talked about companies using 3D printing, crowdsourcing, etc, but to make real world products.

Part of the reason I think this area is hot is that it's harder to do than apps. Every "app" I can think of has already been done, and in fact there's probably a dozen versions of it languishing in app stores. Manufacturing is harder, and is often geographically local, so there are fewer competitors and more niches.

Another leading indicator for me is the general rebellion of young people against the fact that "shop class" has been taken out of schools. Lots of kids are trying to find ways to be "makers". In my state, when I was in school the "dummies" were pushed toward taking vocational classes in plumbing, welding, etc. Now (20+ years later) the vocational classes are the most competitive, prestigious classes that students fight to get admitted to.

If I had to guess, the new manufacturing is going to be smaller scale, extremely high quality, locally sourced materials, with some kind of digital "twist" on the business models.

You should look at how VC firms are structured. I believe they are partnerships amongst the partners, where each partner has an LLC that makes investments on his/her behalf.

I could be totally wrong here. But worth looking into. As others have said, taxes is the main motivator - with a C-Corp investing, you'll be double taxed on any capital gains. The Corp will pay cap gain taxes when it sells shares, and then you or the corp will need to pay more taxes in the form of either dividends, payroll, or more cap gains taxes when you take the money out of the Corp.

And the way to prove if it is true or not is by "reverse induction." Remove one-by-one all the supposed "fruits" (wealth, glory, honor, respect, celebrity, etc) of your labors. And determine if it is still really important to you. Or to Us.

hackuser 2 days ago 0 replies      
Let's remember that the vast majority of jobs are non-technical and held by people without college degrees. Most of the middle class don't have college degrees, and of course very few have technical jobs.[0]

My point is that the range of possibilities is immense. Nobody could possibly answer your question, especially without knowing more about you. Here's some general advice from a stranger on the Internet:

1) Self-knowledge is most important, IMHO, to career choice. Learn what you care about, what inspires you, what you like and don't like, what your strengths and weaknesses are, etc. Most people have a poor understanding of these things.

2) Based on that, embark on a career in something you love and which suits you well. It will take plenty of time and effort to get traction and build 'career capital';[1] it will seem impossible to get your foot in the door, but be patient and persistent and use the time to acquire skills and contacts - you will be very busy later. You might as well invest that effort in something you love. That way, later, when a contact calls you with a business idea or you come across some great opportunity, it will be to do what you love instead of something you merely endure.

3) No matter what you do, some people will tell you it's wrong. You can't please everyone, and they really don't know you the way you do (see #1). Ignore most advice (especially from strangers on the Internet).

----

[0] A quick search of formal education levels didn't find anything but I did find that only 40% of middle-class students who start college get a degree, so the number with degrees is very likely lower. http://money.cnn.com/2015/03/25/news/economy/middle-class-ki...

A lot of jobs can lead to being middle class if you a) sticjpk with them/get good and b) manage your personal finances well.

Some janitor left millions to charity. He was frugal and was good at investing in stocks.

I have read that the 5% of people who have financial goals outperform the 95% without them -- combined.

I have also read that people who folow their interests typically have more career success. People who like what they are doing tend to do it well, for a variety of reasons.

I suggest you figure out what you enjoy doing and try to find a job that is a good fit for that to the best of your ability. Also, learn to budget, stay healthy, use birth control consistently. Health issues and unplanned children seriously derail personal budgets.

Best.

acesubido 2 days ago 0 replies      
It depends on the type of development work you'll be working in. The main role of a Solutions Engineer is to translate marketing vision into technical specs. Take note on the word "vision", it means the customer will have high expectations because usually marketing/sales will present your product like it can do everything. Solutions Engineers mainly deal with high-touch sales, only means one thing: large enterprise customers.

If the customers you'll be handling would be up in AWS/Google, it's good, but if they have on-premise, that means you'll really have to know your stuff about the following:

- Feature Lists - translating what the product does into a feature list that describes perfectly what the customers are looking for. Makes it easier for them to explain to the board so they can get budget and approach finance and procurement.

- Active Directory or Auth0 integrations

- Network - from DNS/dnsmasq to iptables

- VA stuff - meeting generic hardening requirements and VA scans, java key stores, SSL certificates/ciphers and ton of Linux/Unix or Powershell.

- Linux/Unix - NTP, mail servers if need be, proxying using nginx/apache, user access, etc.

- Architecture - explaining the entire product in high-level and how components integrate with a customers current infrastructure

- Benchmarking - customers will ask apples to apples comparisons with other vendors, and they'll stick by your numbers.

- Appliance/Infrastructure sizing - you'll probably take part by this. Certain customers will definitely ask data growth and network growth as well. They need this to line up corporate budget.

and a lot more

So being a web developer is just a piece of the pie. Full stack is a must.
