Those ads are supposed to be "Clearly labeled" and "Separate from answers".
Now, this is the sort of rock-solid commitment to trust and safety that steadily gets worse every year until you go from old Netflix to Poob with ads. But the water's still fine. As a frog, let me tell you, it doesn't feel hot at all.
That's ironic, because the "no end" form was already a relatively new idiom. But "to no end" has already overtaken it in terms of popularity. Of course I meant the word "ironic" like I mean the word "literally"; which is to say, figuratively.
Being a prescriptivist creates no end of everyday pains. Language just won't conform.
Right. You won't learn from a computer architecture book or a uarch guide about SSA form, or LICM, or other famous compiler principle like the central role of inlining decisions ("the mother of all optimizations"). I don't have a good resource to recommend here, this is where my lack of formal training bites. "Go read a hundred blog articles by compiler experts" doesn't feel like very useful advice.
>Knowing how to make sure the compiler sees through a given construct to give you the low level expression you want is too much art and randomness; we need better ways to express optimization expectations so that if the compiler fails to match expectations it becomes a loud compiler error.
There's a parallel with hardware there. Verilog is a kind of hardware language designed for an abstract simulator, in the same way than C is designed for a standard abstract machine for the sake of portability. You end up with an idea of the assembly/RTL you want the compiler/synthetizer to generate in your head, and then it's a game of writing the right pattern that will be recognized and generate the output you want.
I think this is partially unavoidable, because we're inherently asking the compiler to generate a non-portable target-specific output in what is supposed to be a portable high-level language. If you start injecting compiler hints or requirements in your "portable" code, it all becomes a bit of a mess. Part of the problem is also that the high-level languages we're using were designed at a time were many questions were still unsettled. Things like signed integers being two's complements is a recent change in C and C++. But I think some of it is intrinsic impedance mismatch between high-level code and machine code.
I'm not sure I would like a proliferation of annotations that direct exactly how the compiler should optimize (like "must use cmov/csel here"), because if internal optimizer choices become public API, people will rely on internals in their large legacy codebases. I expect this would be a force that ossifies the compiler and prevent optimizations from improving. The "register" and "inline" keywords in C used to mean something to the compiler. But they were misused, having them be a requirement would have held back performance more than anything.
Then again I accepted the same justification against Postgres planner hints, and now that the idea has been recast as a plan stability feature I'm actually very happy with that idea. I'm uncomfortable with letting old calcified codebases hold back compiler internal, but at the same time once you find a way to have the compiler generate what you want, there's a real need to not have it break silently when you upgrade.
You could read compiler books, but I would actually recommend reading about CPUs and computer architecture directly. If you understand how the hardware works, then the optimizations are all very natural and fit into the picture perfectly, instead of being some arcane compiler magic that you have to take as a disconnected fact.
Personally I actually haven't read too many books on optimizations, I just absorbed information over years one thing at a time, but something like
Computer Organization and Design is a pretty good intro to the low-level picture. If you want to drown in extremely dense technical topics that will give you a lot of jumping off points to search, read Agner Fog's microarchicture optimization guide (https://www.agner.org/optimize/). It won't tell you what LLVM is doing, but it'll tell you why it's doing it. Fair warning, it's dense and pretty dry.
Then it depends how interested you are in doing low-level nonsense. If you spend a lot of time writing performance oriented systems code, you'll come to use profiling tools that show you the assembly. If you stare at it long enough, you sometimes start to question why the compiler wrote it this way. And you're naturally led as you try to optimize your code to wonder how LLVM is coming up with this ASM that it spits out and why it sometimes gets it wrong.
There's nothing magical or that requires innate talent. You can learn all of this very naturally if you work close to the metal and take the time to question how the abstraction layer below you actually works. If you keep doing this, you eventually find out it's not that deep, it's just a lot of stuff accumulated over time, but none of it particularly difficult or inaccessible.
There is a scale between prise-sensitivity and risk-averseness, from my point of reference large companies are much more risk-averse than they are price sensitive. Of course this will vary, CTOs exist in all sort of different environments.
Price is not the reason people chose AWS. Some companies use Azure. The current startup at $WORK uses yet another smaller Cloud. And yet AWS sill has the clear lead in market share. That's because price is far from the only factor, and not even the main factor.
>Once Q-Day happens, your only source of security is PQ anyway, so if we're going to do hybrids with today's threat model in mind, PQ+PQ is the way you really want to go
I want to broadly agree but I still can't resist arguing :)
EC is really cheap on the CPU and I trust that libsodium's X25519 is implemented pretty solidly. After Q day, the $ price to break EC is still not negligible.
Whereas PQ+PQ is really expensive. I'm anti PQ+PQ hybrid just on cost. PQ+EC is practically free and still inflicts $'s on attackers after Q day (attacks do get cheaper and you discard the EC at some point, but practically I don't see EC as instantly worthless).
The large enterprise vendors are not prise-sensitive. They're on AWS because you never get fired for picking AWS, and there isn't really any other choice for these vendors regardless of AWS ripping you off.
At this point S3 is a standard interface. All sorts of cloud providers and open-source projects provide S3. If you're on AWS, price isn't the reason. You pick AWS because you don't see your company taking a risk with anything else.
S3 doesn't mean expensive. AWS does. But AWS users are fully locked-in, they'll pay whatever the price is.
And notability isn't just for spam, the core difficulty with Wikipedia is that people disagree about what should be written in articles. The site only functions because of a masterful Jiu-jitsu move where we redirect heated arguments about what Wikipedia should say into heated arguments about which Reliable Source to cite.
That's the fundamental underlying reason behind all the rules and all the deletion discussions. It's not that the article isn't important, it's not that the content is wrong or not useful or that we don't want it. It's that Wikipedia would be pure chaos if it let people just write without sources, and the fights over content would never end.
Notability just boils down to "can we find enough reliable sources to write an article we can verify and stand behind?". Just quoting what authors of the topic say about their own work would of course fall a little short of what people expect from an encyclopedia.
The Satish 2012 study that seems to have started this trend was a small cohort of 22 people split in 6 smaller groups where they also just injected pure CO2 in a small room. There have been several attempts to reproduce, which sometimes found no clear effect, or a significantly smaller effect.
This original study has been used to market these CO2 monitors for years, but the evidence is quite thin and doesn't support a strong effect. It seems likely that there is a small effect, and it has been wildly exaggerated thanks to a small study with N=22.
Well, it depends. Sometimes in math you do a lot of chipping away at a problem, and eventually a bigger result falls after all the right foundations are built. That seems to describe bottom-up building.
On the other hand when a new high-level concept becomes clear and seems to emerge like a revelation, and people start thinking in terms of those new definitions, it seems that a hundred pages worth of smaller results can fall out of it almost effortlessly. This way of describing it is more top-down.
I don't know that there's an exact parallel with software. Math keeps feeding into itself in a way that software dreams about with our ambitions of code reuse. The old Object Oriented dreams of perfectly encapsulated classes and abstractions partially worked out, but not to the degree that was envisioned.
The current situation with package managers doesn't look like a tower that keeps growing higher and higher levels of abstractions. It looks like a tower where each person wants to place one tiny brick that they call left-pad, and next year we will rebuild the lower levels instead of going higher. So the top-down and bottom-up building that we do is different. We keep rebuilding the bottom, and we don't very much like when the tower of abstractions get too tall and hard to reason about.

For complex recipe graphs beyond vanilla train routing is also way more efficient. You get to reuse the same rail network, and sometimes not have to route dedicated belts for 6 low throuput ingredients from all over the map
I feel like a lot of the challenge in early Pyanodons is place-and-route and belt congestion. Unlocking trains feels amazing. They're definitely optimal for a lot of recipes in that mod I think
Spruce up is unreasonably charitable. I'm more irritated that the authorship information is misleading. craig-kerstiens is not available on Huggingface, and yet not a single sentence in this article seems to have been typed on a keyboard.
When Claude writes things like "as someone who has spent a lot of time doing X", I think this is also a kind of failure of alignment. LLMs shouldn't write as if they had personal experience. It's something a person might say in the training data, but I just think LLMs shouldn't claim life experience they don't have, even if that's a statistically likely sequence of tokens.
>And of course, how do you know all the postings on your site are actually fully factual and not exaggerated in any way?
You don't, but you smile and just delete the content. And then you've done your part as a platform. You're very happy to delete things when notified, and you do it promptly. Then you get to publish a very factual transparency notice.
Someone will have archived the page already? Social media is upset when they hear that the big company tried to attack the small independent site to take down this page that They Don't Want You To See? That's out of your hands, you're a neutral platform and you've done your part.
You just need to fold immediately, and you're covered by all the safe harbor neutral platform protections. Same as forums, social media, any website with user-generated content.
Now that won't stop an asshole from suing you over frivolous nonsense. But it does make it easy to throw their suit away - like you said, if you have the spite and money to follow through with a defense.
