I was forcefully relocated from my comfortable decade-old Debian home into OS X, and the package management here in unsatisfying.

I'm looking forward to future posts that show how Nix is better than Homebrew or MacPorts, because that hasn't been demonstrated so far.

And as a bikeshed nitpick, I was always unhappy with the meaningless rpm options, preferring apt's clearer options (rpm -qa vs aptitude search). I'm a bit disappointed that nix chose to mimic rpm's style. Oh well, tomayto/tomahto.

I understood the conclusion to be that perceived difficulty (stress) while writing code is linked to poor quality.

"code elements that are perceived more difficult by developers also end up having more quality concerns found in peer code reviews"
For me the biggest benefit is reproducibility. I can get a package to build on any machine exactly the same and with no hidden dependencies.
My take? Tough. Use ChaCha/Poly. It's a better design for other reasons (mostly not related to TLS, but still).

Same with curves. Nobody really benefits from selectable 25519 vs 448.
With cyber warfare becoming a real thing, imagine a third party hacking into Tesla's update mechanisms and pushing a silent update to overheat the engine or crash into as many casualties as possible.
> “Since introducing this hardware 18 months ago we’ve accrued 780 million miles,” said Anderson. “We can use all of that data on our servers to look for how people are using our cars and how we can improve things.” Every 10 hours Tesla gets another million miles worth of data, he said.

For those following the space, this is an amusing quote, because a RAND study recently came out pointing that given known human accident rates, to have a statistically significant improvement in safety would require data from - gasp - hundreds of millions of miles of self-driving car travel, and with an expensive testing fleet of as many as 100 cars, why, that would take decades!

Not that the calculations were wrong, but I think everyone kinda laughed at it, and this quote emphasizes why.

Anyway, this is the sort of method you would expect. Everyone who can records car telemetry and does training/evaluation on simulations using that data. The only surprising thing here, I guess, is that Tesla is doing evaluation live rather than recording everything and pushing to Tesla servers and running the simulations there.

When I read this article and also when I see quadcopter endurance tests (just over two hours) I come to the same conclusion as you do. Electric jets aren't happening.

So it is so strange and fascinating that Elon Must seems to think that it could be done.[1] Like: if we take todays lightest and most aerodynamic sail plane, add batteries and an electric motor, and it's still worse than a cessna [2] - how exactly does he reach the conclusion that electric jets, _vertically starting and landing_ jets, are feasible? I really wish for something like the hyperloop design-docs to explain the thinking behind it :)

[1] e.g. http://bgr.com/2016/02/07/elon-musk-electric-jet-great-idea/ - “Well I have been thinking about the vertical takeoff and landing of an electric jet a bit more,” Musk said. “And I think I have something that might be close. I’m quite tempted to do something about it.”

Stop buying such shitty bulbs. I moved into my house 8 years ago and replaced the incandescent as they burned out. Most within the first year. Of all of the bulbs I have replaced, not a single one has failed. The only ones that have failed me are some that came packaged in with a new light fixture. Those were the pits.

Worse, the bulbs in the lamps came from my previous home, and have been going strong for a decade now. I've been wanting to upgrade to LED bulbs when they finally burn out, but they've been too damn reliable.

There is a light at the end of the tunnel (hah) with a couple of bulbs that now won't turn on unless you tap them a bit. They're roughly a decade old and have been used for many hours, so I guess it's finally time.
That's mentioned in the article.

It's the scientific concensus (unless you reject all of the evidence that's out there for the past 15 years).

We have multiple receptors in our eyes to do signalling, it's likely that only the S cone cell (low wavelength receptor) suppresses melatonin.

This study found no melatonin suppression for higher wavelength light:
http://www.ncbi.nlm.nih.gov/pubmed/14962066

This study also showed the wavelength effect (may be the first big publication on the topic?):
http://www.ncbi.nlm.nih.gov/pubmed/11763987

In addition, not only is it an observed effect, but it can be harnessed. This study showed increase in salivary melatonin by using glasses that filtered lower wavelengths of light:
http://www.ncbi.nlm.nih.gov/pubmed/15713707

The effect is such a strong one that it was discovered despite not being one of the measurements in an unrelated experiment on breast cancer.

And throughout antiquity, the only light at night we're exposed to has been that of fire, which is a higher wavelength source.
"""biology uses a more straightforward encoding, where some of the 64 possible triples just don’t represent anything"""

I don't think this is strictly true, 61 of the 64 codons translate into 1 of 20 amino acids, and the other 3 are "stop" codons, which I'd argue do represent something. (and at least one of those is sometimes translated as well: https://en.wikipedia.org/wiki/Selenocysteine)

> If you think your research is better, build the product.

I've been saying since the announcement of Ara (and even earlier with that Phonebloks Kickstarter) that it will not work.

So if you'd like to put it that way... I guess my research was better. Also, I have not built a modular phone, but neither has Google. Since I didn't spend 2 years not building the phone, I guess my non-existent product is better too.
I wish it would be safe for those to out their offenders...I really wonder which CEO would think to ask such a ridiculous and offensive question.
Yes. I'm unconfortable doing this as well. Not only with Nix, I really think you shouldn't do it, ever. On Ubuntu/Debian, at least, I'm installing the .deb package.

Why does it have to run on the customers vehicle? Why not just let customers opt in to sending telemetry, and test with that data. It seems like a pointless risk to run the tests live.

Zara (or more generally Inditex) does quality control in Spain, but a small part of the products are manufactured in Spain.

Their Bangladesh suppliers have ~300,000 workers vs. ~6,000 in Spain [0]. To counter your point, it seems that a piece of clothing manufactured in China will be shipped to Spain, quality controlled, tagged, fitted with RF-ID and then sent back to China for selling [1]. So it doesn't seem to follow the model you suggest where proximity matters.

Physicists will typically say "friction force", or "van der Waals force", or "centrifugal force" etc. when we talk about the interactions of ordinary things. These are all caused by the four fundamental forces (or they are ficticious, like the centrifugal force).

And yes, the non-fundamental forces (like friction) are complex interactions of fundamental forces. For friction it's the sum of electric forces between atoms. The important point is that an atomistic model of friction gives you an essentially unsolvable problem, while the effective macroscopic model of friction is high school stuff.

Where did you read that they plan to open-source it later?
That does seem pretty cool, and I also see it works out-of-the-box on Linux machines. It doesn't seem to have a homebrew-cask equivalent though, which is a bit of a bummer. (Makes sense though since GUI applications aren't really cross-platform.)

How does it handle OS-specific dependencies/distinctions? Or if e.g. a package requires ruby or python to be installed?
Absolutely. I don't mean to equate them, except in the ways I mentioned, which is that they're warmer and cheaper than the US. I mention them together because I've lived in both.

Taiwan is much more developed than Cambodia, and yes, are nothing like Somalia. That's not a place I would choose to live, myself.
Quite interesting, I've always wondered about pre-migration through on the field duplicate-logging. Any other company doing this ?
Your assumption is that the experts would necessarily be fund managers rather than individual investors or people getting away with insider trading.
I think your last point hits the nail on the head. There's a large amount of risk (especially at Twitter's size), and nobody wants to be saddled with an enormous and embarrassing failure. In addition, you need many hands to build the system, and finding developers for <favorite lang> that ALSO have relevant experience could be difficult. You could make arguments that developers in <favorite lang> are 10x as productive as your typical Java dev, but few people are going to take that chance. I'd say even Scala is still considered bleeding-edge at a lot of companies.
Thanks for the comment - I'm part of the team here at SMI and did a little work on this post.

We look at engagement and churn because they're largely independent of genre, or if you're even a game, for that matter - those metrics are used to evaluate to SaaS companies, websites, even service businesses. This is because those metrics a proxy for whether your customers want what you're selling.

Certain categories of apps (and subcategories of games) have different averages for engagement and retention, but overall more is better for both. Candy Crush and Miitomo are similar in that they're light, broad-appeal social games (compared to Clash, a harder core game). Yet the metrics of the King games are more similar to each other than Candy Crush and Miitomo are.

App store rank is mostly a function of download velocity. Downloads tell you nothing about the forward prospects of a game. Miitomo fell in the rankings as the initial attention wore off, but if users were sticking around it could have been the start of a new powerhouse franchise.

Revenue isn't related to downloads as only people who use your app have the opportunity to give you money. This the reason we look at active users.

We looked at revenue internally, but it's not a particularly interesting story. Most games settle at a level of revenue-per-active-user and don't move all that much over time. So revenue is dependent on your active users.

Definitely open to any other feedback if you think there's something else we should look at: intelligence AT surveymonkey

On the front end, it's easy——Add a couple lines to a configuration file, make a couple images, and it's done.

The difficult part is that the search is not optimized to be RAM-efficient; each city takes between two and ten gigabytes of RAM. You also need to have several hundred thousand tile images, which are commercially available, but not free.

If you've got a hefty server and the images, then it takes about a computer-day to compute the features and create the search index.

No, you don't get to ask for a citation when I'm asking you the question. "What's more likely, divorce or marriage until death?"

You answered...

> Probably, the latter.

I'd say probably the former. Neither of us has provided any data to back up those opinions but I don't think you can rationally look around you and honestly claim you've seen more people married until death than people who got divorced especially in light of people with multiple marriages. Every divorce counts and I'd certainly wager the number of divorces is greater than the number widows/widowers.
I recently set up a new server for a toy project with nixos and it was a pleasurable experience, even if I did have to pull together several sources of somewhat thin documentation. Recommended. Next time I set up a new dev machine I'm going to give nix a try for dev environment management.

Directed evolution is, I believe, one of a select few developments like CRISPR that will define the future of bioengineering. It is the same thing to biology as engineering is to physics: the utilization of an understanding of complex systems and their laws to create things that make our lives better and more sustainable. I am ecstatic that Frances Arnold's work has been recognized and I think that in the future many Nobel Prizes will be awarded for the application of directed evolution or its development as a method.

For example, there is an archaebacteria (the exact name of which escapes me at this moment) that is critical for providing bioavailable nitrogen on very young volcanic islands. It is unique because no other organism in the tree of life is capable of nitrogen fixation in the presence of oxygen, requiring expensive mitochondria-like adaptations like quasi-organelles to do so. This is why most plants leave it to soil bacteria, because they can not support the process without huge expenditures of energy that would cripple their survival. This is one of the primary problems with agriculture since you need to flood the providers with nitrogen in the form of fertilizer in order to support the density of modern farming.

There are at least half a dozen research groups trying to force this archaebacteria to evolve to a point where it can carry out nitrogen fixation in the presence of oxygen while doing it at a much lower temperature than it evolved for, which is roughly 100° C. If any of them succeed, we will entirely replace synthetic nitrogen sources in fertilizer with a bacteria that can provide the nitrogen from the atmosohere, eliminating some of the worst environmental impacts of agriculture.

Directed evolution has a very bright future.
Thank you for the substantive summary. These click-bait headlines make me want to tune out entirely.

The install script (for Nix, at least) is written such that it will not execute if partially downloaded, so that is less of an issue.

Though I do agree wholeheartedly that piping scripts to shell, sight unseen, is a remarkably awful idea.
Because the amount of data on the CAN Bus is many orders of magnitude larger than that which is sent as telemetry. Presumably the new features need to run on the raw data stream. I fail to see the pointless risk of logging what the computer would have done.
When I purchased my Paperwhite, it was in small part due to the frustration that came with variable font sizes from different books.

We use it on Python projects instead of virtualenv. A problem that you sometimes have with virtualenv is that you must install libpq-dev and python headers and what not to install from pip if the package has native extensions.

With Nix you just declare postgresql as your package inputs and you are done. All needed parts to build and install psycopg2 are there.

Your package/project is completely isolated from your OS libs.
The script doesn't run if it downloads. Go read it yourself.

I have, years ago in college (Econ concentration and some justice/ethics courses to go with engineering major).

I am speaking on a micro-scale. Individual people with low skills and no capital. It's not at all clear to me that minimum wage laws and social safety nets with sharp claw-backs or cliffs (where money earned doesn't help at all or not much) help this class as a whole. Sure, minimum wage laws probably prop up many in the class who have jobs but harms those in the class who don't.

For me, I've run two small businesses and now am a happy employee. It's amazingly aggravating to deal with having employees and it's perfectly proper to me that my employer makes more profit on my labor than I take home. They should: they take all the risk that I'm a lemon employee and provide the structure whereby I can concentrate on where I can add vale and all the stuff I couldn't care less about (HR, Finance, Legal structure, IP, etc) they handle.

If I start a third company, it probably won't have any low-skill workers at all, certainly not if there's a min wage law that makes it uneconomical to hire them. On a micro scale, I'm deciding what's best for my company, not for the economy or for society.

Edit: I should also clarify that in my GP post that I was referring to the payment of minimum wage at a rate higher than the value creation as a form of "charity", not that all low-skilled work (paid at free market wages) is charity. One of the appealing aspects of most UBI proposals is the "U" in that they don't scale back benefits as punishment for gainful employment.

I didn't ask for a citation in response to your question, I asked that in response to your answer "Statistics" to the grandparent posts question "Who says divorce is the expected outcome of marriage?"

If your claim is that statistics say that, then where are the statistics?
I imagine it's a pragmatic consideration, if they're installing it on that many vehicles- that's a shitload of telemetry to stream over whatever data connection these cars have, and then have tesla devote however much computer power to post-processing;

vs. current approach of distribute the processing among all those scads of nodes, and have them only upload the interesting parts.
