> I'm not sure that bodes well for smart watches selling at 4+ figures.

I'm pretty sure the smart watch makers don't expect them to last for too many years, definitely not decades. After all, they want to be selling you a smart-er watch in just a few years.

This consumerism drives the whole thing, if your new watch was to last decades it would be designed in a whole different manner. And it's not only the chips, you won't be able to get a compatible display, battery, PCB or case or anything to replace a broken/worn out one in just a few years.

This sad state of consumerism is why I do woodworking to balance my mind. The pinewood dovetail box I built last week will still be there when I'm dead.

I don't know the codebase, but if for example, there's a project wide standard or convention for what the variable j means, then it could be OK. Or at least not as bad as it first appears. Not all code has to be written for an assumed stranger on the street trying to sight-read it.
Most of the Wikipedia articles on technical subjects, and especially on mathematical topics, are terrible as introductory exposition. They are jargony, highly technical, and self referential. They usually contain much that is irrelevant, and they almost never properly explain the context for an idea.

The main problem is that Wikipedia articles are tiny and atomic, so it’s difficult to synthesize and organize ideas into a coherent story. The culture of Wikipedia frowns on the kind of exposition found in textbooks or lectures. And perhaps most importantly, no one is responsible for either individual articles or sets of related articles in a field. Working within those confines is not the best way to spend your time if the goal is to give future generations a leg up, in my opinion.

If you want to learn about mathematics, even a mediocre textbook is nearly always better than the relevant Wikipedia pages. The Wikipedia pages are then useful later, as a reference, for people who already understand their content.
Compiling LilyPond scores (http://lilybin.com). Usually we have at most 1 user at any time, but we can also handle bursts, like when a classroom of 30 students all use it at the same time. Ends up even cheaper than running one VM that can only handle 2–3 simultaneous users.
We had cases where failing MySQL queries[1] would leave behind GigaBytes of garbage data that we (as users of Amazon's RDS) have to pay for and have no option of removing (besides killing the entire database and rebuilding a new one, which would cost us more than just living with the garbage). Having our own small EC2 instance with MySQL on it would have saved us quite a few hours of work/downtime.

[1] Have a database of a few gigabytes of sizes, start an ``ALTER TABLE`` and wait until your pre-allocated disk space is filled up. The query dies and you just fucked yourself. Can happen unexpectedly: We tried to remove a non-existing index on a table and MySQL decided to FIRST copy the entire table and THEN report that there is no such index.

An adjustment in the allocation of funds would allow counties to bring more road graders and operators online. Right now I believe they simply dont have the capacity to do proper maintenance on all of the level A roads on a frequent enough basis. This might also allow for the conversion of some state highway routes and level B roads to level A roads.

The legit disagreement seems to be between WF's approach and the Bogleheads argument that you only need three funds. I lean toward the former but haven't been satisfied with any of the analysis around this honestly.

I'm all for a replacement for BAM file format and the quality scores. Ideally something that supports delta based encoding to a reference genome similar to CRAM and something that more compactly represents quality of bases sequenced.

In the meantime as a user of BAM I'm very very very grateful for faster zlib as it makes life a lot better with the current large installed base of programs that use BAM and data sets in BAM. These sort of improvements really do make a meaningful difference in the same way that switching to SSDs from magnetic disks didn't improve the implementation of my software but makes my computer a lot faster to boot up and compile things.

First of all, you are probably not taking full advantage of tax-efficient accounts. Are you contributing your maximums, including back door strategies?

Second, you can do substantially better than Wealthfront with even an extremely lazy portfolio. Heck, put all of your funds into a Vanguard target-date fund (the laziest of the laziest) and you will do better than Wealthfront, with only 15 min of effort per year to rebalance.

The kind of tax loss harvesting Wealthfront does is usually a pseudo-benefit. You're usually in a better position just holding until you need distributions for retirement. On paper it sometimes works out, but only when you make assumptions that generally involve timing the market to harvest without loss while avoiding wash sale rules.

That said, if you can't be trusted or can't trust yourself to buy a simple lazy portfolio and hold for decades, then by all means pay the 0.25% annual fee to have someone else take the management keys away from you. As one of my coworkers said, Wealthfront is lazy advice -- telling someone to use Wealthfront is easy to do and usually gets that person into a better position than they otherwise would be, and requires minimal effort from me in advising them. But it is not the optimal solution out there and anyone can easily do better if they are willing to learn and capable of exerting self control.

And if you tell the compiler not to care, it won't be doing that reaction (only the 'free' detection) and I thought you already stipulated that your hypothetical code would be doing math where that simply didn't happen, meaning that the expensive reaction would not be triggered.

I just looked at the pricing page on Gitlab.com and was genuinely interested in trying it out. But the pricing language and structure on the page turned me off instantly.

I thought to myself: "$3.25 per user per month? Sweet! I can throw $6.5 to try it out without the hassle of setting up yet another VM. Charged yearly? Eh, seems to be a bit of a commitment. Oh wait, in multiples of 10? that's $390 upfront with 8 extra licenses for a year!"

Compare that to Digital Ocean's pricing page: https://www.digitalocean.com/pricing/

They list the monthly price first but they actually bill hourly. It seems more honest and upfront to tell me what I'm in for.

I understand that you're competitive compared to Github enterprise, but I think that page needs some work to make it more trustworthy and less salesman-pitch-y. Even Github lists that they start from $2500 upfront, not $3.25 + read the fine print.

Best of luck to you and congratulations on the funding.

That would only solve the problem of not penalizing existing retirees. It would force all people currently saving for retirement to save 10-15% more to pay this new pile of tax. And what, precisely, do they get in return for that added tax burden?
> Evasion is a different thing than non-payment. No act that occurred in the past that was not evasion when it occurred becomes evasion as a result of this change in application.

Incorrect, but I can see how you might think so. It is the same because if I disagree with the IRS and refuse payment then according to https://www.law.cornell.edu/wex/tax_evasion, I have committed tax evasion.

So yes, since the IRS can adjust my tax burden retroactively, tax evasion is involved. Suppose in 2012 I filed my tax returns and was fully honest. The IRS agreed, but now in 2015 they change the 'interpretation', and if I disagree with the new tax they are levying on me, presto chango! I can now be convicted of tax evasion for refusing to pay this arbitrary retroactive tax.

I can't help but notice that this looks more like an enterprise integration tool (think mulesoft) than API management (think apogee.. or I think that is what they do).

Speaking somewhat from experience (webmethods, caml, spring-integration and various other enterprise integration tools) they always want you to use "their" DSL which is often not even stored on the developers filesystem (ie webmethods... you submit the code to the "broker" or "rules engine" or "router"... lots of words for thing that does the work). Which leads to very awkward development.

Consequently I wonder if they will have git integration because writing code even snippets in a web form no matter how nice gets old fast.

Here too. One of the gravel roads near me was recently paved and they simply flattened it, added some sort of cement + water spray (as opposed to the usual multiple inches thick layer of concrete) and the asphalt placed on top of that. It is definitely better than gravel, but it's already showing some wear in places.
That makes sense... and your are definitely right, quite a few YC companies use Python as well

Thanks for the response
I think the same could happen in closed source projects as well.
It sounds like you're arguing that people wouldn't understand new results if they were more open. Most people I know well are educated/intelligent and could understand leading-edge research results within their own field, so I disagree. (And I don't work at a university!)

Even if only a minority of the public understood publicly-available research, having all results open could change the way the world works. It was hard to see how the information-sharing of the internet would change the world, so I can understand how this is hard to see as well.

You also hint that science deserves more wide-spread respect, and that the world be better off if people were better educated and tended to be more scientifically-minded. I agree with that!

tldr: OpenGL is great. But, the hardware model it is based on is long outdated. The mantra for the past decade has been "Do your work in huge batches if your want peak performance". But, modern hardware is very capable of getting great perf out of lots of small batches if they are set up correctly. Unfortunately, doing that in OGL requires complicated extensions to work around the old design (AZDO).

That's the big driver. But, there's also a lot of good improvements over OGL that can be made given the past 30 years of hindsight. Not the least of which is a much simpler, more consistent, more reliable, more maintainable driver model (ex: Don't ship a custom, rushed, underfunded compiler in every OS update of every Android device and just point at the spec doc when people complain that they each parse the same code slightly differently from each other.)

I watched the Usenix talk on packetdrill, and while it's a really neat tool it seems to me that it doesn't really support timing very well.

The tests are run in real time - running 650 tests take almost half hour, which would normally be considered completely unacceptable for any kind of TDD. The timing can also vary from one run to another, so all timestamps have a few milliseconds of wiggle room automatically, and a small proportion of runs (1/2500) still fail randomly due to timer inaccuracies. And unit tests that fail non-deterministically are really unpalatable. Is the talk outdated re: these issues?

Great hack despite that, and I would certainly have loved to write a scripting language for expressing tests rather than use C++. And the packet syntax they've chosen is probably superior to what I ended up with. But what I describe in the post dates back to 2011, so packetdrill wasn't yet around for us to take inspiration from :-/

I am surprised that Amazon did not add support to more API description formats like RAML or apiblueprint. It is such a key feature. If I wanted to use this service in front of existing APIs, even only one API, I would not want to go through the work of having to redefine all my endpoints through a web form!

Shameless plug: after working on several API projects, I have been researching ways to not have to "code" over and over again what goes into creating endpoints, it became so repetitive. Lately, I turned to RAML (Yaml for REST) and, with 4 other developers, we created an opensource project called Ramses. It creates a fully functional API from a RAML file. It is a bit opinionated but having to "just" edit a Yaml file when building a new API simplified my life. As a bonus, I also get a documentation and a javascript client generated from the same file.

EDIT: forgot the url https://github.com/brandicted/ramses and url of a quick start tutorial: https://realpython.com/blog/python/create-a-rest-api-in-minu...
Electron-beam lithography is a technique that works, but because it's very slow, it's also very expensive. There are efforts to parallelize e-beam writing, but they face hard challenges. For example, if you want to pattern faster, you just need to shoot more electrons. But if you shoot too many electrons, they repel each other and the pattern blurs. It's a difficult problem to overcome, but people are working on it.

You're lucky if you get a huge negative number. Signed integer overflow is undefined behavior and may have awkward consequences when coupled with compiler optimization. E.g. if(x+1 > x) may be replaced with if(true) legally.

And this is why computers programs are fast. Yes, it may be a good idea to do something else in a high level language but if your kernel, web browser, etc were written with a nanny language that checks for every possible corner case for every operation, it would be painfully slow. Integer addition arithmetic is one of the most common operations your computer does, making that 2-10x or more slower would have catastrophic consequences.

And despite all this "danger", your kernel and web browser and http server just work.
