What Go Programmers Think of AI
“Most Go developers are now using AI-powered development tools when seeking information (e.g., learning how to use a module) or toiling (e.g., writing repetitive blocks of similar code).” That’s one of the conclusions Google’s Go team drew from September’s big survey of 5,379 Go developers.

But the survey also found that among Go developers using AI-powered tools, “their satisfaction with these tools is m … ⌘ Read more

Linux 7.0 Aims To Replace More Caching Code With Sheaves For “Hopefully” Improved Performance
Introduced to the mainline Linux kernel last year was “sheaves” as an opt-in per-CPU array-based caching layer.

Another project where I’m going to use my terminal widget toolkit is a hex editor. This is still very young, obviously, and there’s a lot of work to do (both in the toolkit and this particular application), but I’m making some progress:

https://movq.de/v/2bae14ed16/vid-1769283187.mp4

Since this program is UTF-8 clean (I hope), you can do things like enter multi-byte UTF-8 sequences or paste them from the system clipboard (another hex editor I just tried failed to do this correctly):

https://movq.de/v/e9241034c1/vid-1769283755.mp4

Under the hood, I’m using mmap() with MAP_PRIVATE, which is really cool: I get the entire file as a byte array, no matter how large it is, no need to actually read it upfront; and MAP_PRIVATE means that I can write to this area however I like without changing the underlying file. The kernel does copy-on-write for me. Only when you hit Save, it will write to the filesystem. And it’s just a couple lines of code. The kernel does all the magic. 🥳

Spent basically the entire day (except for the mandatory walk) fighting with Python’s type hints. But, the result is that my widget toolkit now passes mypy --strict.

I really, really don’t want to write larger pieces of software without static typing anymore. With dynamic typing, you must test every code path in your program to catch even the most basic errors. pylint helps a bit (doesn’t need type hints), but that’s really not enough.

Also, somewhere along the way, I picked up a very bad (Python) programming style. (Actually, I know exactly where I picked that up, but I don’t want to point the finger now.) This style makes heavy use of dicts and tuples instead of proper classes. That works for small scripts, but it very quickly turns into an absolute mess once the program grows. Prime example: jenny. 😩

I have a love-hate relationship with Python’s type hints, because they are meaningless at runtime, so they can be utterly misleading. I’m beginning to like them as an additional safety-net, though.

(But really, if correctness is the goal, you either need to invest a ton of time to get 100% test coverage – or don’t use Python.)

yes, yes that’s right. Mu (µ) now has a built-in LSP server for fans of VS Code / VSCodium 😅 You just go install ./cmd/mu-lsp/... and install the VS extension and hey presto 🥳 You get outlines of any Mu source, Find References and Go to Definition!

@prologic@twtxt.net I’d love to take a look at the code. 😅

I’m kind of curious to know how much Assembly I need vs. How much of a microkernel can I build purely in Mu (µ)? 🤔

Can’t really answer that, because I only made a working kernel for 16-bit real mode yet. That is 99% C, though, only syscall entry points are Assembly. (The OpenWatcom compiler provides C wrappers for triggering software interrupts, which makes things easier.)

But in long mode? No idea yet. 😅 At least changing the page tables will require a tiny little bit of Assembly.
