Pretty similar recommendation was given in Halacha (Jewish law). Since observance of commandments is time based, this question arises already on Earth, for example in the polar regions, which don't have regular night / day cycle. In orbit and etc. Those are all cases within Earth vicinity though.

More interesting question would be, what happens during an interplanetary space flight. What about other planets altogether, like Moon or even Mars? And then of course what about interstellar deep space flights? So far this wasn't discussed extensively, but quite possible some of those soon won't be theoretical questions anymore.

Interestingly, this topic is mentioned by Robert Heinlein in "The Moon Is a Harsh Mistress"[1].

For that to be true all the socialist or communist states that have failed, or generally to live up to expectations, would have to be devoid of science. Which I'd posit isn't the case.
There's a whole different section of rules for bullying. For example, picture of someone urinating in their pants == OK, unless there is a caption calling it out in a derogatory fashion. Unless the person is a public figure (more rules to define this), then the derogatory caption == OK.

Won't YC get diluted along with the founders? That 7% will end up being less than 5% after a few rounds of VC when the founders' collective share of the company is 40-60%.

7% for $120k is a pre-money valuation of ~$1.6M. The value of a startup is not just its present value but also includes its expected future value. If you believe that your startup is worth less than that before YC, it makes sense to sell as much as possible at that valuation.

On the flip side, that is a post-money (and post-YC) valuation of over $1.7M. I think any reasonable founder would expect their startup to be worth at least $2M after going through YC - for the Rolodex and for the 3 months of heads down focus that it forces you to do.

C and Fortran both obey IEEE 754 and have well-defined arithmetic exceptions on most platforms -- but programmers usually instruct the compilers to ignore all that in the interests of faster code.

As for what the differences are, try talking to a compiler engineer. The better ones love how Fortran features like the argument aliasing rule for 100% of code makes generating fast code easier. In fact that's one of my tests for compiler engineers in interviews; if they've worked on a C/C++/Fortran compiler and can't say anything good about the challenges and opportunities of Fortran optimization relative to C/C++, then they haven't really drilled down on performance issues!
This is fantastic! I'm looking forward to following this projects progress. I lived in Dallas for a while and loved the way the city integrates green space into the urban landscape. I'm not surprised that Dallas would be the city to take on a project of this scope.
At least in OpenBLAS, most (all?) of the BLAS routines are C functions that call kernels written in assembly, but many of the LAPACK routines are the Netlib reference Fortran versions.
Lots of gold in this book. Even though it was published in 1930, just like with The Prince mentioned elsewhere in this thread, human nature changes so very slowly - if at all - that these works are only substantiated by the test of time. Definitely a must read.
A glide ration of 12:1 is not great, but isn't exactly brick-like either. A Cessna 172 has a glide ratio of about 9:1. Pilots spend a lot of time practicing gliding in airplanes like that (Cessnas, Pipers, etc) during primary training.

I doubt they practice it much in 767s, though, despite the fact that they actually glide better. :)
What insight could you possibly hope to gain by this?

Social media has no relevance to work performance.
In modern lean software product development with continuous delivery there is no longer a "project" as such with a defined finish. The team just pulls features from the backlog in a never-ending stream (perhaps with a planning cadence layered on top) until the product reaches the end of its lifecycle and the business cuts off program funding.

To illustrate your point, Facebook censored the Pulitzer Prize-winning photo taken June 8, 1972 with crying children, including 9-year-old Kim Phuc, after an aerial napalm attack on suspected Viet Cong hiding places.

That photo violates a several of Facebook "ban" rules, but is an exception to the rules. After much outcry, Facebook reversed their rule-based ban.
The Look of Fake News (700+ screenshots of fake news sites)
Basically, OPs article gives a good overview on what scientists want out of a language used for large scale numeric simulations.

1.) Multi-dim arrays supporting array math, slicing and flexible indexing, sizeof always known (internally solved through lookup tables).

2.) Fast-by-default rather than safe-by-default. A safe language is useless if it gives 2x or more runtime overhead. Make it safe where it doesn't give you any performance penalty (i.e. compile-time checks), otherwise make the default performant or leave the choice to the programmer. Example: Pass-by-reference as default, no GC.

Essentially, I don't think Fortran will be replaced any time soon - maybe strong AI that can program all of this stuff from pure math specification will be here sooner than a Fortran replacement. To everyone not understanding this, read the article again. There's been a huge amount of effort going into this language the last 20 or so years - almost more than justified by the size of the HPC market, which is visible by all the compilers lagging behind the specs. If you want to help, go and improve gfortran (e.g. with better GPU support so people don't need the lagging PGI or locked down Cray compilers anymore).

It's technically interesting and competition is never bad.

A fringe operating system can drive innovation by taking risks that a mainstream OS would never. Ultimately any improvements will appear on main stream operating systems so even if it's never used we're going to see some benefits.

Insomuch as I've seen HPC code written by science academics, both when I was one and later when I became an HPC guy, as much as I cringe at some of the Fortran, the C/C++ can be far worse... and I wish that I could retroactively restrict some of my colleagues and customers to sticking with Fortran.

This is the hardest lesson to learn for fresh young engineers. Their job isn't to create wonderful new designs, it's to serve the needs of their company - which may involve creating wonderful new designs, if they're lucky, but it may not.
Has been using it in production for quite a long time now, wrote my own key-value store server running on top of RocksDB. I hope somebody writes a good and stable key value store server, I tried using ardb (https://github.com/yinqiwen/ardb) but was not happy with it's memory consumption.
HyperDex is pretty interesting.

I evaluated it for a project last year, but decided not to use it. One reason was that at the time, the project seemed to have been abandoned; the author did not respond to issues or pull requests. Another was that based on Google searches, there seemed to be no one else actually using it in production; so even considering getting the commercial ACID support seemed like a big gamble, never mind that I couldn't find any info on how it performed in large clusters, and so on.

That said, it seemed technically brilliant, and fast.

If Escriva can accomplish the same thing with Consus, in a fully open source way, and gain traction enough to keep the project alive, I could see this as something I would consider using. That said, I'm wary of anyone who just abandons projects like that, without telling anyone about it.
Why don't you want to use Fortran?

If you want to get started, here's my recommendation: Program Kernels only in Modern Fortran, learn about f2py bindings and do the other parts in NumPy. If you use Fortran purely as a number crunching language - no I/O, no setup, no config code etc. - it's pretty sweet actually - IMO there isn't much need for replacing it with something new that has 50 years of compiler work to catch up (which is near impossible anyways).

What group with resources do you think it actually takes equivalent resources to join?

In any case I'm disagreeing with devoply's use of "can't". If he wrote this I wouldn't have disagreed: "Want to make money? You choose not to because your group does not have money and you prefer not to join or associate with a group that does."

I agree that many people have feelings tying them to a particular group and are unwilling to leave their group. That's a matter of willingness, not ability.

While I think you have some good points, and I'm not a huge fan of Plethora (like I said, their service was unusable for me), I think what we have here is people coming from different perspectives.

You understand real hardcore manufacturing and have a lot of experience in that realm. Plethora seems to be targeting people that don't know anything about manufacturing but want an easy way to build parts in small quantities. I don't know how they plan to scale to full manufacturing, and I don't know their numbers (the real question is retention, how many customers are coming back with larger order numbers), they may have found a niche by targeting customers that just don't know any better. I assume this market is small and I am skeptical of its value at all, since I know it's easier to just hire someone internally or just outsource it to a competent shop, but something Silicon Valley can do like nobody else is hype itself up. What that means is a lot of things, but it includes pumping up valuations for an eventual acquisition.

Is Plethora creating real value? I'm extremely skeptical. Are they attempting to create a company that can be sold for a profit? That seems pretty likely to me, and that's what the overwhelming majority of investors care about.

I think part of the problem is Nick sounds like he's pitching investors in this thread, when he's talking to people that are experienced in manufacturing. You're not his target audience. Then again, I doubt he's planning on showing this to investors, so I'm not really sure what his goal is here (unless he's just defensive, which is a really bad sign for him being able to see the forest for the trees).

There's two places where I find LISPs useful.

* Where I might prototype something in Python usually, I can build the Scheme equivalent just as fast, and thanks to Gambit or Chicken's speed and static compiling, it can grow to be bigger than just a prototype with few tradeoffs.

* Anytime I need a DSL, if it isn't LISP, I find myself either disappointed by slowness, or fighting with the language. Example: HTML templates. (x-expr are great!)

In short, speed and flexibility.

Trying to beat the S&P is a sucker's game. Very few people can take the volatility of it, let alone the other investments that the author proposes here.

The 74 logic family is gone, because it's been fully obsoleted by newer logic families (especially 74LS and 74HC). The vast majority of parts from the 74 family are available in these families, which generally have compatible behavior, equivalent or higher speed, and much lower power draw.

There are some old parts from the 74 family which were never brought over (like the 7447 seven-segment decoder), but all of the basic logic parts are still around.

When people talk about stress, they don't usually mean just the normal healthy sort of pressure and motivation, although yes, that's technically "stress". You've dropped to a silly semantic game if you read the article about people having totally unrealistic expectations and working overtime without pay and think "what's wrong with stress?" as your main take-away.
I have no expertise in this area, so I have no idea if you are right or wrong.

That said, I think you comment would be more useful to people like me if you said for several specific points what is the truth that the author got wrong, and also gave a link to an article for non-experts that gets things right.
I've done this professionally for the last 18 months or so and basically how it works is the agency will get in a project, perhaps it's short or long. My contracts range from 3 weeks to 6 months. The agency doesn't want to hire someone on just for this project because maybe they only get a project like this once every 2 years. You get a desk, sometimes a computer, credentials and are basically an employee. You rock up 9-5 like everyone else. At the end of the contract you'll either get extended if they have more work or you'll be onto the next thing. You should be getting paid a bit more for this than if you were an employee because you're often foregoing benefits like sick/annual leave and general job security.
Shit job or no job. That is a question. And probably one should not ask Amazon for answer.

Nice bit of trivia! I was an admin of a Primos machine briefly while also doing scientific programming.

Primos wasn't much good compared to the commercial Unixes that were appearing. It did have one nice-ish feature late in it's history; the CPL scripting language.
Right; "drivers" that run only on a microcontroller in the device, don't touch the host's CPU, are called firmware. :)
Most specialty (in the higher up numbers there are quite a lot of these) parts only existed in a single family anyway. But basic stuff, muxes, dividers, registers/drivers etc. all made it to HCMOS :)

The fuel imbalance check-sheet also points out to make sure that the fuel imbalance isn't the result of a leak, and they did (somewhat -- it was dark outside) try to check for a leak.

They could also have looked at the rate of fuel consumption across both tanks to determine that the fuel consumption on the right tank was way higher than the engine could consume, but that was not SOP at the time (it is now, and the A330 [and probably other planes] now compute that information and alarm on it).

Its all layers, planes, with minimal exception, really don't crash from a single failure.
I never did, but I often wonder if it was due more to a lack of exposure than anything else. Back then, one's exploration was somewhat limited to what resources the surrounding adults provided you with. And when none of those surrounding adults are "computer people" in a useful sense, you don't get exposed to all that much. The computer itself, and its supporting documentation, tended to just dangle BASIC in front of your face and little else.

The problem is that you can't say this for sure in the USA.

Java's owner, Oracle, demonstrated more than enough bad will regarding their
language's users (Google with their Dalvik), and the legal system in US
allowed them to have a say with regard to something that they should never
ever been granted to (a separate implementation that mimicked what the
original publicly commited to do).

You, not being Oracle, can't tell when, how, nor who they will strike again,
and legal system in the US is fscked up enough to allow them to win, no matter
how ridiculous their claim will be.
In that class students design and implement in logic gate level simulator a 32-bit RISC CPU.

Is that an euphemism to avoid saying "MIPS"? ;-)

One way to really cut down on hardware (and speed) is to use a bit-serial design, as found on some minicomputers in the 70s. Memory elements like registers still need the full width, but by processing only 1 bit at a time, many of the other components in the datapath can be reduced by a factor of 32. You can also get left and right shifts for "free" since that's intrinsic in the design. Another strategy is to use microcode to break down instructions even further, e.g. reuse the ALU to do address calculations and incrementing the instruction pointer.

My experience at a largely Windows based Fortune 1000 company was that Windows is that hard. I dealt with 12-ish factor apps on Linux exclusively, but the teams dealing with legacy stuff on Windows really struggled. If you're very careful with the tooling you may get lucky, but I watched as things like Chef, Sensu, and Collectd all took significantly more effort on the Windows platforms.
It's OK, you have a strong opinion with little basis in fact. That's an opinion in truest form.

I'm not misusing straw man. You argued against things I wasn't saying. That's a straw man. You tried to defend that free market dogma by attacked arguments about communism and socialism that nobody but your straw man was mentioning.

You are now continuing to make more straw men. None of the rest of your comment is actually addressing anything I was saying, just arguing with some image you have of people who you think believe certain things.

Note that I happen to think your perspective is really skewed here — the vast majority of power in our society is vested in capitalist interests, the media and government and lots more are very much capitalist or capitalist-apologist, and truly dogmatic free-market ideologies (it doesn't matter whether there's a great-man behind some dogma, just the idea that the authority is some idealistic free-market theory, that's authority enough to be called "dogma" — it's super rampant, enough that it's easy to run into believers constantly.
What a bad article. I mean, starting from the very first parapgraph:

> What puzzles me about the discussions around “fake news”, is how everybody in favor of free speech is now calling for censorship. Like, really? Don’t you see where this will lead — ”a Ministry of Truth” and other things that only 1984 could have envisioned.

There is no one prominent who is arguing for unilateral government censorship of fake news sites. What has been proposed are a series of reforms, usually outside of the legal system, to help people identify blatantly incorrect but otherwise convincing-looking articles on big platforms like Facebook, which bears no resemblance to anything Orwellian.
