Great news. I look forward to Microsoft installing this on my computer for me.

More specifically, tail recursion is usually easy to turn into a loop. Tail calls can be difficult to turn into loops when they call a different function, or worse a function passed in as a variable.

You get 256 colors per frame. Want more colors? Use more frames! There's some really impressive software/gifs at https://gif.ski/ if you want to see just how far it's possible to push this terrible format.

It's interesting that cert pinning cuts both ways though. It can also be a tool to give users power against the IT department (typically indistinguishable from malware)

Given that proofs must be finite (or it's easy to prove falsehoods), maybe the title is appropriate then.

strncpy is fine as long as it's not used in isolation. My preferred pattern (when I want the truncation) is to use it, and then unconditionally set the last byte of the buffer to null. This will always result in a valid C string.

Ah, but what if it writes so far off the array that it messes with the contents of another variable on the stack that is currently cached in a register? Should the compiler reload that register because the out of bounds write might have upd

Calling a piracy app "malicious" seems like a huge stretch. Am I missing something, or was this written by the copyright holders?

Maybe choice was stronger than I needed. Thinking about it more, I think the problem is that BB isn't even definable (that I can see) without LEM. There's an "either the machine halts or it doesn't" baked in to the

Is there a variant of "there exists a program that prints BB(8000)" that doesn't rely on some sort of axiom of choice? Maybe the intuitionists have a more useful definition of computibility if it doesn't posit that such

Racket has a sophisticated system for dealing with phases in its macro system: https://docs.racket-lang.org/guide/phases.html I don't know if other schemes use a similar system.

Not pointless to a compiler writer. If a compiler is certain there's UB should it format the developer's hard drive immediately, or does it have to wait until the program is run before formatting to be standards compliant? On a mo

Emacs already restricts what variables can be set as file-local. It will prompt you to ask what to do if you open a file containing: ;; -*- eval: (message "arbitrary code") -*- any mode associated with a file extension shou

You should see how much difference adding or removing a '*' can make in C when setting something to 0. I've written that bug before.

They have both. In the demos they were sending select complex tasks out to chatgpt with a large UI alert confirming the data was leaving Apple's walled garden.

Perfect. We'll just build an AI to translate things into a "genuine" tone for the customer. All problems in society will be solved by adding a layer of AI indirection. </s>

The more complicated the codec, the more fascinating the failure modes. I love watching a digital TV with a bad signal, because the motion tracking in the codec causes people to wear previous, glitched frames as a skin while they move.

HM is worst-case exponential, but it just happens to have good performance in practice.

I'll go a step further and say that users should be able to distribute software without needing to get apple's approval. Instead we get the lie of "_ is damaged and can't be opened. You should move it to the Trash."

Checking that we've gotten better at dealing with novelty seems like a very hard thing to do. Everyone knows black swans exist, they're famous for it!
