AFAIK this hasn't been taught since the 40s. Now (since the late 60s) there are 3 different cursive scripts available, and it's up to the school to decide which one to teach (if any). When I went to school, the one I learned was S

In terms of format string syntax, Rust is extremely similar to Python (and C++'s new std::format is also similar). So in that sense it seems Python-style "{name:fmt}" has won. Though the others don't support arbitrary ex

Agreed about TS, but Python type annotations are not ignored. They are executed as code (all type annotations are valid expressions) and the results are stored on the module/class/function object that contains the annotated variab

Optical disc media is pretty great, if only they didn't scratch so easily... Or get completely destroyed if something sticks to the label side and you try to pull it off... Or delaminate themselves from old age... Enclosed discs like M

From reading the readme, it seems the Language was designed to explore increasing compile speed, and producing optimized code without using LLVM. Yet all the comments are about the syntax. Never change, programmers. Personally, I would have

Very impressive PoC. The exploit, meanwhile... Seriously? `grep; rm -rf ~` is parsed as `grep` followed by a bunch of stuff, so just ask the user if `grep` is allowed and execute it? Was their permission system vibe coded? Gross incompetenc

I remember thinking this post was outdated when I first read it. "Safe strings and unsafe strings have the same type - string - so we need to give them different naming conventions." I thought "Surely the solution is to give

Yeah it's exactly AJAX. Except instead of writing Javascript to send requests and insert the response into the document, you use declarative HTML attributes to describe what you want to happen.

I strongly dislike "this feature could be abused, so we won't add it" as reasoning for language design decisions. It just doesn't sit right with me. I think designing to avoid "misuse" (i.e. accidentally shooti

Yeah, it would be much clearer if instead of an `a is b` operator, there was a `same_object(a, b)` built-in method.

Wow, definitely much more than I expected from the title. Really enjoyed the surprise mini-talk about the origin of entity-component-system in the Q&A section as well.

People don't complain about DX portability because Windows has first-party support for Vulkan and OpenGL, unlike macOS. Also, since the XBox also uses DirectX, you get two birds with one stone. And third, you aren't forced to use

Yes, I agree. The same way that when you ask "Are there any production codebases written in Language X", you typically mean "excluding the Language X compiler & tooling itself." Because of course everyone writing a t

Some examples that come to mind: You can inspect the call stack, and get a list of local variables of your callers. You can assign to object.__class__ to dynamically change an existing object's class at runtime. You can overwrite every

Both of them, "Digital Rights Management" as a term and the Direct Rendering Manager, are about the same age. The legal term for it, from the DMCA, "Technological Protection Measures", also conflicts with another acronym

Thank you for the breakdown. Since we're on the topic of having to trust X, is there any reason to believe X wouldn't insert some code into the client JS (behind some per-account flag) to exfiltrate your key or PIN, if they were o

Enum is what they call it (perhaps to appear more familiar to C++ programmers?), but from a computer science standpoint they are classic sum types.

In normal safe code, the compiler ensures your code has no UB. In an unsafe block, the programmer ensures the code has no UB. Safe abstractions are created out of unsafe operations by making sure it's impossible to violate the operatio

That's not how mouse input works though, right? If I move my mouse cursor to 10,10, and then pick up the mouse and set it down somewhere else, it's still at coordinates 10,10. You don't need the mouse's physical absolute
