This is exactly the kind of technical pedantry I keep coming back to HN for.

I worked as a software engineer for well over a decade before I got my degree. You can learn everything you need to know without a formal education. However, if I was hiring, all else being equal, I'd choose the candidate with a degree

What if there is significant disagreement within the medical profession itself? For example, isotretinoin is proscribed for acne in many countries, but in other countries the drug is banned or access restricted due to adverse side effects.

Typos feel way harder to spot in proportional fonts. Maybe because proportional fonts are easier to read so your brain subconsciously ignores them. And typos, like a misplaced or forgotten comma, can cause some of the most annoying bugs. Al

Lazard agrees with you: https://www.lazard.com/media/uounhon4/lazards-lcoeplus-june-... Marginal costs of $108 for gas peaking and $31 for combined cycle. $48-$107 actual LCOE ($77.5 average).

I think you misunderstand. DP is not equal to "caching", but in the set of all things that are "caching" DP is contained. I cannot think of any DP algorithm that does not explicitly or implicitly use a memory cache. Can

by bjourne 1y ago
No definition of "caching" I know imply global shared state. Local private caches are commonplace.

But dp is a form of caching, no? It sacrifices space by caching intermediate results to compute successive results. The only reason it is called dp is because the "inventor" (Iirc Bell) needed a cool name.

If shorter distances were correlated with more peace there wouldn't be a genocide in Gaza, since the distance from Gaza to Tel Aviv is only about 70 km. More travel may have other advantages, but peace doesn't seem to be one of th

Good luck storing your private keys in environment variables!

No, that's an anti-feature. :) Sibling comments here claim that command line arguments "leak" whereas environment variables does not. It's plain wrong. An attacker with access to arbitrary processes' cmdline surely

Then how would you SET the API key in the first place? :) The argument doesn't make any sense at all.

Neophytes take notice. Attention to details like this is what separates truly great programmers from merely good ones. That said, for scripts reusable by others you should use command line arguments . Environment variables in lieu of comman

Like Wikipedia tries to catalogue all useful knowledge in the world, a standard library should catalogue all useful modules in the world. The problem is that tools and community structures we have are not advanced enough to support that wor

4 KiB page sizes have been used since the 1960's. More memory doesn't necessarily mean that larger pages are beneficial. Maybe 16 KiB is better for Android? Maybe. There really is no clear consensus on what the optimal page size f

by bjourne 1y ago
That's a valid point, but isn't memory protection the only common user-visible effect of changed page sizes? It would seem most apps which do not use write-protected memory would be unaffected.

Well, I wrote "in spirit". The point is that Rust, on average, needs to recompile much more code per change than a language that relies on small and self-contained compilation units.

That is basically what Oh My Zsh does for zsh: https://ohmyz.sh/ Even if you don't use zsh you can look at the source code and adapt the prompts for the shell you are using.

I believe the Rust compiler does whole program analysis or, at least, something very similar in spirit. Hence, unless you completely change how the language works it can't be as fast as a simpler compiler. You can work around it by hav

Yes, yes, and yes. Teams is absolute trash. Slack + Google stuff + Zoom works way better ime. But you have to experience it yourself. It's meaningless to try and list everything that works poorly in Teams.

The proof of the pudding is in the eating. That is, if you can produce a working (free) implementation demonstrating the superiority of your protocol then there is huge value. If you can't there is no value.

Those annotations create a compile-time enforced typological relationship between the input and output values of the function. Python doesn't have mandatory type-checking so it can't do that. But parent wasn't referring to ty

What can a Haskell monad do that a Python class cannot? 99% of all monads I've seen only facilitate local state manipulation.

I think lottery is a great analogy to contemporary society. Although those with the winning tickets have done their darndest to convince others that it was skill and hard work that got them the tickets.
