The problem is that if you call another function, you won't know whether that function is uses any instructions that require alignment. So in practice, only leaf functions can skip stack alignment. The ABI states that the stack point

For my beginner programming class, I have them use a script `compile` which handles compilation and linking, while also enabling enabling all the warnings/errors I think are helpful, and also doing the above redirection. An absolute be

A typical grocery store will carry on the order of 40,000 unique products. Costco is hard limited to a max of 3,700 unique products. If a store wants to bring a new product in, something must be rotated out. This also means that if a prod

TurboVision was distributed as source with some of the Borland tools, and later open-sourced, I think. So it's not a rewrite, just a port to non-DOS terminals.

The implementation of inheritance (more specifically, polymorphism and dynamic dispatch via vtables) is a problem in games, because it adds an extra layer of indirection, and screws with cache locality. But the semantics of inheritance

Is that article correct, that mixed DPI on Wayland works by just rendering everything to a virtual screen whose resolution corresponds to the maximum DPI of any physical screen, and then downscaling all the other screens?

It's worth pointing out how different (and better) Jedi Knight's morality system is from the "Bethesda model", in which you play as good/bad but at the end of the game, it doesn't matter and you get to make the

My brother and I made a mod in which you played as an Ugnaught (the little guys running around cloud city) wielding a wrench instead of a lightsaber. For some reason we thought it was hilarious to replace the main villain with Bob Saget.

Yeah, but if every project, no matter how small, required you to spin up and maintain a full Postgres install, surely you'd start thinking, there has to be something easier than this... The problem with Git is the same kind of problem

You're essentially correct; in JS, if you write for(var i = 0; i < arr.length; ++i) ... then the array's length is not read once at the beginning of the loop; it is read every loop iteration. So if the code

It's kind of weird that these days, many (most?) projects use Cmake directly as their build tool. They don't generate a VC or Xcode project and then work from that; they generate a VC project and then immediately build it . The

In other words, it's not just as simple as "figure out how to compile things on this system, once, and then reuse that information in the future". Different projects can be compiled with different options, cross-compilation

You linked to the wrong section (again); that covers how ATC should handle unmanned balloons, not what the balloon operator should do. You probably meant [FAR part 101]( https://www.ecfr.gov/current/title-14/chapter

It's rather ironic that the one old file format I've tried to open in LibreOffice, namely, old StarOffice 5 files, do not open. (LibreOffice forked from OpenOffice, which was the open-sourcing of StarOffice.) The converters were

It doesn't "corrupt" them; it converts them to JSON strings. It's in the name. Expecting `JSON.stringify` to throw in those situations would be like expecting `str` in Python to throw.

There's a donut shop near me named Loi's Donuts. Not Lois's or Lois'. Yes, the owner's name is Lois, not Loi. I guess the apostrophe just means, Hey, there's an "S" coming up!

The rule for college/uni I've always heard (and repeated to my students) is 2 hrs outside of class for every hour in class. So a 4 unit (= 4 in-class hours/week) class should have 8 hrs of outside time dedicated to studying

I've heard O(n²) described as the most dangerous asymptotic complexity, because it seems fine for small testing inputs but falls down when you throw real-world -sized data at it.
