I agree, this would be useful. Another one I would like is auto-vectorization, a way to mark a loop with an attribute and if it fails to auto-vectorize, the compiler should print out the auto-vectorization report for that loop, explaining w

Yeah, that's the way virtual machines have been written forever, some version of for instruction in instructions { switch (instruction) { case OPCODE_X: //.... case OPCODE_Y: //

Yes, that is correct. You cannot do this trick in standard C, C++ or Rust, it requires some version of [[musttail]]. Strong argument for adding it to the C standard, IMHO.

by OskarS 2y ago
Obviously compilers have been doing tail call elimination for ever, but for this trick "generates [tail calls] quite reliably" is not enough: you have to GUARANTEE it (or fail compilation), otherwise this structure does not work (

It will be MUCH less, and much less complex than this.

I so much more appreciate this style of version numbering compared to being eternally 0.something.

Isn't the fundamental issue here not so much anything to do with `<svg>`, but with the fact that you can't easily include HTML snippets from other files in HTML? Like, the only reason not use the <svg> tag seems to be

If that SELECT query is too much for you, I agree, SQLite is maybe not meant for you. Not a very solid argument against SQLite, though.

Exactly. The difference here is that std::variant doesn’t “name” the options, you just get the type (and an index, so variant can contain duplicate types). So you have to have some marker type that’s like “this contains nothing”. Fundamenta

You're not wrong, if you just want "a T or nothing", optional is the way to go. But what if you want "a T, a U, a V, or nothing"? Then you do std::variant<std::monostate, T, U, V> Or std::option

A huge bummer about Guile (and that is frankly shocking for a language designed to be embeddable) is that it relies on a bunch of global state, which means that you can't embed multiple interpreters a single process. This totally kills

For sure, no question! There's a reason people choose Microsoft. My question was narrower, just the question on reliability (hence "all else being equal"). I don't think you can say that, leaving aside issues like this,

Please tell me you've ended the contract with CrowdStrike after this?

Can you say with a straight face that if you were designing a system that had extremely high requirements of reliability that you would choose Windows over Linux? Like, all other things being equal? I'm sorry, but that would be an insa

It's not just that. If ALL that was in the header was the function prototype, that adds basically nothing to the compile time. The problem is when you have significant codegen and parsing in headers, like you do with templates and clas

Good tip! Yeah, the `sort -rh` is what makes it sing, it's such a cool feature of coreutils that `sort` knows how to sort human-readable output from `du` or `df`

by OskarS 2y ago
I've used graphical tools very similar to this, and I always come back to this: du -h | sort -rh | less (might have to sudo that du depending on current folder. on macos, use gsort) You just immediately see exactly what you nee

There is another scenario where this is an issue: if this code ends up in a header which is included in a lot of places. You might say "that's dumb, don't do that", but there is a real tendency in C++ for things to migra

This is a very weird thread: half the people are arguing that having these timestamps is not a realistic security problem at all, and the other half is arguing that any fix to it has to have Fort Knox level security policies. It seems to me

You store the key in the database, right? Like, if the database leaks, it doesn’t matter if your ids are sequeneced or unsequenced, because all data has leaked anyway. The key leaking doesn’t seem like a realistic security issue.

Can I ask (as a humble application developer, not a backend/database person), if the two requirements are: 1. The UUIDs should be ordered internally, for B-tree performance 2. The UUIDs should not be ordered externally, for security re

Ah, fair enough. I've only tested the Rust version. Yeah, important to note, in practice it is always finite, since if you try to do anything "real" using this trick, you blow the stack immediately. This was mostly just a fun

It actually is, because it allows functions as first class objects. That means you can use the fixed-point combinators from lambda calculus (which doesn't have direct recursion either). For instance, the Omega combinator (sort-of):

I will admit that I really miss the "value semantics" thing that RAII gives you when working in Zig. A good example is collections, like hash tables or whatever: ownership is super clear in C++/Rust. When the hash tables goes

It's very true. When watching programming talks on YouTube, I often hover the mouse over the time bar to find the first preview which looks like the slide has syntax highlighted code on it. I'm here for the cool coding stuff, not

Personally, I think this is a great policy! Local news is incredibly important to the health of a democracy (somebody needs to show up at those city council meetings and report on them, and national media wont do it), but it's doing qu

Totally! People in these kinds of environments have no leg to stand on criticizing a free and open source project. If you don't like it, don't use it, but CERTAINLY do not demand of the developers that they honor your requests whe

It's very easy to design a schema that breaks up blobs into chunks. SQLite is excellent for memory constrained environments, with even mathematical proofs of maximum memory usage: https://www.sqlite.org/malloc.html
