Another common convention is to select a suitable letter: for types with no particular meaning, go T, U, V, &c.; for types with meaning, see if there’s a better letter, e.g. Map<K, V> for a key-value map.

Rust convention is to mostly use this style of single-letter generics, but not to shy away from using longer names like regular type where useful (but not to prefix them like TFoo).
> Mostly I think that these things probably belong outside the scheme

Yeah, I think somethings count as "meta documentation" and are "documentation about the documentation" instead of the actual documentation.

"contribution guides" to me are definitely that, "introductions" are mostly that. I reckon licenses are probably "meta documentation" too (since they'll also be in the source code). "release notes" are a bit of a grey area in my head (I'd consider at least major version update release notes and any depreciation/removal of features to be "part of the doco".
It's not mandatory to get a TV license, but they will harass you and strongly imply you're a fraud if you don't get one. You can fill in a declaration stating that you don't need one to make the harassment go away for a year. I refused to do so out of principle and eventually I got a letter saying they "opened an investigation" in to me, but I never heard more about it. shrug.

You should consider trying home-manager as the other reply mentioned, because it lets you stay in non-NixOS land until you get comfortable. I use my home-manager config both on NixOS and on Ubuntu to not only to handle stereotypical dotfiles like Neovim and Tmux, but also things like setting dconf keys so that GNOME is instantly set up the way I want it on any new installs.

What is pantented about implementations? I’m surprised that the nature of the implementation of a public specification is patentable.

I spent a few years implementing 802.3 physical layer testing. At the conferences it was clear that things were written carefully to not cover implementation, but they went so far in the necessary details that there were only a handful of reasonably performant and economical solutions.
It looks like they fired the engines more than they needed to, while maintaining a stable control curve. That shows that they had enough power to do the low altitude maneuver.

If they had done it higher up, and tweaked things from there they might be stuck using all 3 engines all the time in the future. They needed this data.

If they had fired the 2 engines less, they might not be sure they even had enough power and control to ever make it work. Then they would be forced to do more tests before possibly being forced to resort to more engines later.
Or maybe he said "company" because Amazon is one, and isn't a university. While an interesting conversation could be had about large companies/small companies/university/individual contributions to progress and invention, Bezos isn't necessarily having that conversation, and certainly isn't obliged to contextualize Amazon's achievements that way.
Yes! Visa and Mastercard debit cards are supported.
TypeScript can't always save you against yourself. But adding in the TypeGuard makes the intent explicit. If your guard isn't actually verifying the thing has the structure you say, of course it's going to fail. But at that point your code was going to fail anyway (say if you just cast it to the type), with a less-useful error message.

I don't quite understand the criticism. You may as well say that unit tests are just as unsafe as not writing unit tests, because your test might not do what you think it's doing.
My home sound system is the same, except the speakers aren't producing nearly as much treble as they used to. This is apparently a common issue, and now I need to work out how to get the speaker cases open.
I spent years writing HFT trading systems. I’ve built back testing systems that actually worked. I’ve been out of the industry for more than five years and every order I’ve sent since I left (all through retail brokers including RH) have been limit orders.

I’m going to guess that I’ve spent more time in front of a real market feed than you trying to divine how the orders are impacting the book but who knows.

All that said I’d love to subscribe to your newsletter and learn the secrets to why limit orders have a different tax treatment than market orders.

Also for the record market orders tell the market you have no price sensitivity. If your newsletter could tell me how that’s better for retail investors I’d appreciate it.
> In short, AWS could do a lot more to compete on price if they wanted.

Maybe. GCP can be subsidised by Google, but AWS is the breadwinner for Amazon.
Ahh. The commonly used "open source" term is a synonym in practice for "free software", so if you are a proprietary software vendor that is source-available but calling it "open source" (when really, it's not) is a different type of misleading.

Don't call source-available proprietary software "open source", or say that you'll "always be open source" if you're just going to be source-available for parts.
I like the idea of using relative units for media queries but it interferes with people being able to zoom and get the desired outcome.

Open source and proprietary with source publicly available are not the same thing at all.

I get what you're saying for sure. And obviously some scientists are searching for aliens (literally the definition of SETI), but I assume Loeb knows what he's talking about (program chair of astronomy and astrophysics at Harvard) and that he means that although SOME do it, that most are too scared, so that field of research is stifled.
I think the problem is that it's not obvious why getting super big is bad. Anti-trust is a law around abuse of customers by cornering a market. But what if they haven't abused customers? What if they treat customers really well and otherwise provide a lot of value? Why stop them from becoming that big?

/usr/local/etc is a common pattern, though.

So maybe I would add that /usr/local is a special case of /usr for locally built* stuff, with sub-nodes imitating the corresponding nodes in /.

The Pirate Problem
Didn't quite get out in time. Lost what is a lot of money to me, but very little to most people on HN. I think there is a weird dynamic with us complete investing noobs though. A lot of us are kinda poor, or at least in debt. The "yolo" strategy doesn't seem that bad in many ways.

Even though it's a lot of money to me, the unrealized gains I didn't take and the amount I lost really don't put me in a very different position. Just have to keep grinding away on student loans in either case, only a ~2.5 month swing on my estimated time to finish paying my loans from my bad bet compared to selling at the top, and only 1 month worse compared to not trying at all.

Learned some stuff too, hopefully it'll make me a better investor when I'm able to save some money starting in my mid 30s.
ah, losing money in order to grow. Also known as investing! It's irritating how journalists spin this to imply a company is haemorrhaging cash.
I've felt the "flow state" they allude to near the end on teams I've worked with. Everything just clicks, and there's a sense of cohesion and momentum. Perhaps because it's about sports, the article focuses more on physical descriptions/dimensions, but the common variable I think in the work world is whether or not the culture is high in trust. High-trust work environments (you trust that those around you have your best interests at heart) produce much better work because everyone can put each other and the work first rather than all the overhead/friction of worrying about drama and politics.
Turns out it’s just Tom Brady.
Element.foo being undefined says “foo? What’s foo? I don’t know what you’re talking about.”

Element.{firstChild, nextSibling} being null means “I know what firstChild (or nextSibling) is, but this element doesn’t have one.”

It would be categorically wrong for things like Element.{firstChild, nextSibling} to be undefined.
A basic NAS with a handful of spinning rust drives can easily exceed 1 gigabit/s. A single SSD can as well.
Sure, but start of the "race" was pretty much the reverse - factions in the USA fighting for who will be allowed to launch the first satellite, resulting in the Vanguard fiasco. They had to bring in Von Braun in the end to do it, starting the centralization.

And in the USSR Glushko also played along initially, designing R-7 engines that are in use till today basically. Only later he stopped and started demanding all future engines to be hypergolic, which didn't go well with Korolev, especially for crewed vehicles.
And it would have been avoided entirely if HN simply used relative font measures (em/rem) and allowed the user just set the damn base font size in the browser settings.
Cat5e usually works fine. For longer distances you will need the correct (cat6 or better) though.
> I'm not trying to convince you, I just wanted to answer your question.

Sure it is, if there is a good convincing case, you can in the space of a single comment at least get me to seriously question and re-evaluate my priors, check out your book recommendations, and I would do the rest from there whether I ended up agreeing or disagreeing in the end.

Let’s start with what is the impetus for action? Inaction is easy, it’s the default, but if my Representative (presently Pelosi) or US Senators or their eventual opponents and/or replacements trotted that line about how a company shouldn’t be able to get this big, out without an attempt at a good explanation as why we should cap the size of a corporation’s growth, I would throw them from the average politician column into the crazy column. Not just because they are taking that position, reasonable people can disagree, but because they would be seeking power on that position and they would be seeking an expansion of Federal power and action with that position without justification, without a limiting principle, frankly it looks arbitrary and capricious like an imaginary line that exists only in their mind that no company’s market valuation must ever cross without consequence.

The political will to power that led to the anti-trust legislation, prosecution and conviction wasn’t that the defendants were merely too big for their britches; it was their abuse of a market dominant position that it was argued harmed the public. Even today reasonable people can disagree on whether this was a justifiable course of action on the part of the government, but I am not here to re-litigate historical events.

Is the present position of Amazon and its close peers and the other >$100B companies as measured by their market valuations, not market share, not cash and other assets, but present market valuations, equivalent or like to the situations in the past where the government was willing and able to successfully pull the trigger of the antitrust gun? To reiterate, what is the impetus that we must act given the facts that we have about these contemporary corporations with such immensely high valuations?
Speaking for myself, two items I often find missing: the overall summary and the rationale.

Many times I've gone to a set of documentation wondering what exactly the thing _is_. Let's take the JavaScript language, for example. The very first thing that should be documented is a short description of what exactly JavaScript _is_. This could be a single sentence, should probably be at least a paragraph, and should be no more than a page. It boggles my mind how often this critical piece of information is omitted entirely.

The rationale quickly orients the reader to the landscape of similar solutions. It's very rare that something has no peer of any kind, and it's quite useful to understand why this particular thing exists, and how it can be distinguished from other similar solutions. The Python language, for example, has a number of attributes that separate it from other computer languages. This can be concrete (it comes with constraints that lend themselves to readable programs), or they can be aspirational (Python aspires to be an easy language to pick up, particularly for non developers). This can go deep, and rapidly descends into matter that my be quite useful and interesting, but belongs in an appendix or other separate matter.
So you only told them about your condition after you felt like they were about to fire you? A serious condition you only shared after reading that the US ADA might protect you? Something feels off about this.

A part of your performance might have needed the communication because as you’ve said everyone works remotely for the said company. Lack of communication can disrupt the harmony of the team that makes the company work.

I do feel for you because mental health issue isn’t something anyone should take lightly.

If you were getting fired because of your performance or lack of communication isn’t helping the company anymore without them knowing you were going through this mental health issue, is it really grounds for discrimination? From what I understand they were letting you go because of the communication not because of your mental health.
I distribute binaries. My binaries work on six different operating systems. In order to do that I had to roll my own C library. I'm happy I did that since it's so much better than being required to use six different ones.

I'm not opposed to vDSO but I disagree with how Linux maps it into memory by default. Linux should not be putting anything into the address space that the executable does not specify. MMUs are designed to give each process its own address space. Operating systems that violate that assumption are leaky abstractions imposing requirements where they shouldn't.

The main thing dynamic shared objects accomplish is giving upstream dependencies leverage over your software. They have a long history of being mandated by legal requirements such as LGPL and Microsoft EULAs. It's nice to have the freedom to not link the things.

> if Robinhood couldn't meet the new deposit requirements, I think the existing trades just wouldn't settle (and obviously they wouldn't be accepting new ones)?

Defaulting on clearing obligations is the old school way for a brokerage to go under. The moment that happens, customers’ funds and assets are segregated and what is left goes into receivership. The parent company would then file for bankruptcy protection to avoid being stripped for the broker-dealer.

The point of a clearinghouse is that trades always settle. Certainty in that is paramount. Individual members’ survival is secondary. Which makes sense since it aligns interests.

The way I took it is that you said your original statement in a broader context along the lines of "in computer science form and function should never be separated." And you used that statement to apply it to UI/UX and architecture.

This statement is patently false, especially for UI/UX. Even at the lowest level there are platform agnostic API's (opengl) that are divorced from CPU/computer architecture. At even higher levels, javascript/css/html is a graphics API that is divorced from even the operating system. Separation of form and function is the foundation of software. It cannot be a "fools errand" when all of UI/UX is designed with the separation of form and function in mind.

It is therefore fundamentally impossible for you to stand by a notion that is completely false. More than likely your statement is just a mistake and you didn't think it through. Such is one of the downfalls of "Architects"... they are so concerned with high level truthisms that they fail to even build the correct high level picture of the computing world.

For software systems, the devil is, unfortunately, in the details.
I can transfer $100K (or maybe more) from my bank into Vanguard right now and trade using it instantly while they wait 3-5 days for the deposit to clear. It is definitely a common practice among the larger brokers.
This was an academic channel conference that many people viewed. Perhaps not a popular channel for you but still worthy of existing.
That's not really my experience.

(1) Right now, virtually everyone agrees that individual choice is important and all humans are born with equal rights

(2) If they don't, it's often possible to come up with solutions which work for everyone. The problem is when people jump to solutions ("democracy") rather than problem-statements and first principles.

The early US is a good examples of -- actually quite exactly -- your contrived example. The South had slavery. The North didn't. There was an overarching federal government which dealt with military and foreign diplomacy. It worked for a bit over a half-century until it didn't, mostly for reasons unrelated to why it worked as long as it did (the expansion of northern culture west upset the design, as it had an upper hand in congress).

My claim is that there are systems of government which do a better job of protecting individual choice and equal rights than capitalist democracy. My claim is that if you articulated your value system completely (probably not on a web forum but over an hour-long coffee), we could probably design a better one around your values, which also did better for most people's values. My claim is also that if you've signed an NDA, you probably don't have all that much individual liberty.
Are there any dedicated server hosters that give you 100Gbps private networking among your servers?
Yeah, I imagine that managing one's expectations is the most vital at the formation stages, which could be what is meant.
Is there any evidence any of these 'bad' actors are running their own GANs yet? I've yet to see an analysis of where the pictures come from.

This is possibly a way to attack future tracking, thousands of GAN generated pictures of oneself to pollute databases.

It's hard to know if it will work since the databases can use the same reputation systems your friends will to keep their info clean. I guess in the coming war we will see.
Well it all depends on how you're expecting your types to be extended. I'm not sure what TypeScript's support for interfaces is like but it might make sense to have interfaces for both (just in case you ever have a product that's both physical and digital).

Tagged unions might get a bit messy if you ever need to extend them, but sometimes you simply have some source / sink of data that requires a variant type.
They allowed only to "Sell" not buying. Not even with cash (no leverage).

In what way, if you don't mind? I always have the impression that he is practical to a fault, and consistent in his prescription for engineering above all.
But it is the fault of TypeScript for having such an obvious path for falling into that trap. Part of what it means to have TypeScript code is to have typing files.

Part of good language design is attempting to minimize bad programming habits. In this case, a language with a HM type system would avoid the issue all together, while affording the same productivity gains from having static types.
the market caps of each department spun out is likely greater than the current market cap of Amazon today.

That is assuming the companies would all be as successful being spun out.
Not being the bottleneck doesn’t make increased throughput completely superfluous. The faster you can communicate across a channel, the quicker you can shut up and get to idle, saving power on both transmission and policing of resource contention. You also have more time to handle locally scoped retries and error correction.
