The biggest problem with monads that I am aware of is that they don't compose: if m1 and m2 are monads, then you can't automatically derive a new monad m3 where m1 (m2 a) and m3 a are equivalent.

Monad transformers are one solution to this. This lets you write the composition rules for m2 once, and then reuse them for every m1. A solution, but boilerplatey.

I don't understand algebraic effects quite as well, but my understanding is that they do simply compose.

You know what's the most interesting part of this whole article? The thing Rust is very famous for, memory safety, did not feature at all.

I think that's the essential point, really... It'd be hard to argue that the rest of Rust isn't overall "better" than C++, but the compromises made to flexibility and ergonomics to achieve memory safety in Rust are the biggest points of contention for Rust critics.

The GBA SDK is pretty minimal in terms of library support. It's mostly functions for accessing save data plus wrappers around syscalls found in the bootrom. Those syscalls are some basic math functions, a few decompression algorithms, and an early version of the MusicPlayer2000 sound engine.

What's so bad about _Generic?

I would not let the name distract you - it's equivalent to overloading, not "generics" (i.e. parametric polymorphism)

In that capacity I think it's quite a lot more sane than C++. Having a closed set of overloads, not having name mangling, not having complex name lookup rules are all a good thing.

Time to put my language lawyering cap on.

C99 §6.7.2.1.13

Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning

C99 §6.7.2.1.13

An implementation may allocate any addressable storage unit large enough to hold a bit-field. If enough space remains, a bit-field that immediately follows another bit-field in a structure shall be packed into adjacent bits of the same unit. If insufficient space remains, whether a bit-field that does not fit is put into the next unit or overlaps adjacent units is implementation-defined. The order of allocation of bit-fields within a unit (high-order to low-order or low-order to high-order) is implementation-defined. The alignment of the addressable storage unit is unspecified.

Which is standardese for pretty much exactly everything you said :)

The consequence of the first rule is that there's only one sane way to lay out structs. The only way to break that rule which I can imagine would be to add extra padding - you can't swap the order of any members under these rules.

Isn't struct layout in C implementation defined in general?

C itself doesn't specify any ABI. A given platform simply uses one as a matter of convention.

Etrian Odyssey released in 2007 and was a fun throwback to this sort of experience. The concept for this game is that the Nintendo DS's touch screen can be used to draw a map and keep notes while dungeon crawling. It's funny to think that it's about as old now as the style of games it was imitating then.

The 3DS also had a note-keeping system built into the main menu and usable in any game, but I don't think many people bothered.

Nothing new under the sun.

Those rights, like to bear arms and freely associate, only exist on paper. That they are in a state of nominal existence and practical abrogation serves to deradicalise and defuse resistance against the government, not encourage it.

I think the point is that Intel had such a lead in the Bulldozer era that for AMD to overtake them was a tremendous failure.

I would not say that the first gen of Zen is was a clear winner over Skylake. It took a couple iterations before AMD clearly took the lead. AMD was simply so far behind that several large generational improvements were needed to do better than Intel.

The first smartphone I owned was a ZTE Blade 13 years ago. As a budget phone, that definitely had compromised performance.

It's been years and years since I ever felt like my phone's performance was holding back its usefulness to me. I have only ever replaced my phone because the battery could no longer hold a charge or the charging port was damaged beyond use.

It has a camera, web browser, chat apps, and receives emails. It also makes calls and texts. It doesn't lag while doing these things. That's plenty.

Ice Lake wasn't the first iteration of 10nm - that was the disastrous Cannon Lake in 2018.

I was approaching it from the perspective of "What would be useful to do on a Wii?" When you approach it from the perspective of "I want to play with Jazelle - what can I use?" it makes much more sense. Thanks.

EDIT: Following one of the reference links, apparently you can enter Jazelle mode on the Nintendo 3DS's application cores. That's another suitable target. https://github.com/SonoSooS/libjz

Array parameters are a lie and have always been evil. I'm only more convinced of that now.

This seems roundabout. If Elon Musk objects to The Onion using InfoWars' X accounts, can't he just make up a reason to ban them after the sale goes through? It's not like X can't unilaterally and arbitrarily close accounts.

This seems very useless. I'm not sure Jazelle was ever used for anything, and I'm not sure why anyone would want to either - least of all on the Wii's IO processor.

Still, this repo links to some other stuff I found interesting. The Starlet exploit which is linked is funny for how basic it is, and it also seems to be part of a much bigger and more ambitious (but mothballed?) project.

Intel just can't stop floundering. Alder Lake and Arrow Lake were talked up a lot, but Alder Lake only approximately caught up to AMD, and Arrow Lake is still well behind.

The most interesting part of this article for me is at the beginning.

Now imagine that calls could specify alternate return points, letting the callee decide the statement to return to:

  // Dreamed-up syntax
  fn f() {
        g() alternate |x| {
          dbg!(x); // x = 123
      };
  }

  fn g() -> () alternate i32 {
      return_alternate 123;
  }

Does there exist a language where some function

  fn foo() -> T throws U 

  fn foo(ifOk: fn(T) -> !, ifExcept: fn(U) -> !) -> !

I'm not sure I've ever seen a bigger case of pissing in the wind than Asahi Linux. I respect the dedication but it takes a special kind of personality to not wash their hands of an affair like this.

Adding onto that, the roadmap to Intel's next generation isn't exactly clear. Arrow Lake Refresh would have seemingly bumped core counts healthily, but that's cancelled now. I don't believe that it's cancelled because its successor is ahead of schedule.

NDS and 3DS cartridges had a similar form factor but operated by a completely different protocol. I expect Switch 2 to do something like that, given that piracy-enabling cartridge emulators for the Switch 1 currently exist.

Modchips on newer Switches use fault injections (clock/voltage glitching) but there exist mitigations for those. The Xbox One is confirmed to use them.

I encourage you to watch this video where Microsoft describes the security design of the Xbox One, which so far has been almost bulletproof.

Would they still support autostereoscopic 3D, though?

I'd kill to see a New 2DS XL with this mod, however...

MIPS II got rid of the load delay slot, so any software relying on that wouldn't work.

The PS2 EE also had a nasty bug which would cause some loops to terminate early. There's a decent chance any random MIPS code would satisfy this bug's conditions.

The Game Boy Micro still contained a useable SM83 and GBC PPU on the SoC, but the cartridge is inaccessible. In theory you might be able to run a tiny payload from WRAM (32KB?) but it's pretty useless otherwise.

I'd be very interested in how they define a book ban. If I can go to any book retailer in some jurisdiction and buy the book I want, it isn't banned.

SSH is one of those swiss army knives which turns out to be much more useful than initially expected. The various port forwarding modes have bailed me out of a few tricky situations.
