@lyse@lyse.isobeef.org Ooh, lovely! 🌇
I’m drowning the noise with this: https://www.youtube.com/watch?v=tgivYC2s6hs 😅
tt that was bugging me for a long time. Previously, when there were empty lines in a markdown multiline code block, the background color of the code block had not been used for the empty lines. So, this then looked as if there were actually several code blocks instead of a single one.
@lyse@lyse.isobeef.org You actually have a Markdown parser/renderer in there? Oh dear. I would have been (well, I am) way too lazy for that. 😅
@prologic@twtxt.net Happy New Year 🥳🎆
@movq@www.uninformativ.de Because they’re just boxes. :-D
@movq@www.uninformativ.de Yeah, I see. Just crudely checked on my computer, with around 0.013 seconds, Python 2.7 seems a tad faster than Python 3.14’s 0.023 seconds in this little program.
The lazy imports sound not too bad, but I just skimmed over them. There are surprisingly many exceptions, but yeah, no way around them. :-)
@movq@www.uninformativ.de Mu (µ)’s startup latency appears to be ~10ms on my machine:
$ time ./bin/mu ./foo.mu
real 0m0.011s
user 0m0.004s
sys 0m0.006s
I assume you made the thing load quickly, didn’t you?
That’s the problem with Python. If you have a couple of files to import, it will take time.
I want this to be reasonably fast on my old Intel NUC from 2016 (Celeron N3050 @ 1.60GHz) and I already notice that the program startup takes about 95 ms (or 125 ms when there are no .pyc files yet). That’s still fine, but it shows that I’ll have to be careful and keep this thing very small …
Python 3.14 will bring lazy imports, maybe that can help in some cases.
@movq@www.uninformativ.de That’s cool! I also like the name of your library. :-) I assume you made the thing load quickly, didn’t you?
@prologic@twtxt.net No, that’s Python/curses on Linux. 😅
@movq@www.uninformativ.de Is this on yout little toy OS? 🤔
Btw, @shinyoukai@neko.laidback.moe, that’s a super cool logo on your yarnd. I like it a lot!
It just doesn’t look aligned properly: https://lyse.isobeef.org/tmp/misalignment.png Could be a yarnd issue, though, it might not expect a logo this large. Just wildguessing, no idea.
@shinyoukai@neko.laidback.moe Because you might not want to commit all changed files in a single commit. I very often make use of this and create several commits. In fact, I like to git add --patch to interactively select which parts of a file go in the next commit. This happens most likely when refactoring during a feature implementation or bug fix. I couldn’t live without that anymore. :-)
If you have a much more organized way of working where this does not come up, you can just git commit --all to include all changed files in the next commit without git adding them first. But new files still have to be git added manually once.
@shinyoukai@neko.laidback.moe Do we now need ad filters in twtxt clients, too? O_o I hope not! Personally, I cannot stand the “Sent with my crappy $phone/$app” e-mail footers.
But congrats on your client. :-)
os.UserConfigDir() up until a few seconds ago! I always implemented that myself.
@shinyoukai@neko.laidback.moe Yeah, they don’t truly support XDG. In fact, I looked in the Go stdlib source code to notice all the differences and shortcomings.
@shinyoukai@neko.laidback.moe Cool, I didn’t know about os.UserConfigDir() up until a few seconds ago! I always implemented that myself.
@movq@www.uninformativ.de Thanks! I’ll have a look at SnipMate. Currently, I’m (mis)using the abbreviation mechanism to expand a code snippet inplace, e.g.
autocmd FileType go inoreab <buffer> testfunc func Test(t *testing.T) {<CR>}<ESC>k0wwi
or this monstrosity:
autocmd FileType go inoreab <buffer> tabletest for _, tt := range []struct {<CR> name string<CR><CR><BS>}{<CR> {<CR> name: "",<CR><BS>},<CR><BS>} {<CR> t.Run(tt.name, func(t *testing.T) {<CR><CR>})<CR><BS>}<ESC>9ki<TAB>
But this of course has the disadvantage that I still have to remove the last space or tab to trigger the expansion by hand again. It’s a bit annoying, but better than typing it out by hand.
@lyse@lyse.isobeef.org Well, I used SnipMate years ago (until 2012). IIRC, it’s more than just “insert a bit of text here”, it can also jump to the correct next location(s) and stuff like that. Don’t remember why I stopped using it.
Then I used nothing for a long time. Just before Christmas, I made my own plugin (… of course …), which does everything I need at the moment (and nothing more).
It can insert simple templates and then jump to the next location:
https://movq.de/v/67cdf7c827/sisni%2Dpython.mp4
And replace a string after insertion:
https://movq.de/v/67cdf7c827/sisni%2Dheader.mp4
(It’s not public (yet?) and it also uses vim9script, so I guess it wouldn’t work on your system.)
lldb or gdb 😂
@prologic@twtxt.net Debugging this stuff on bare metal hardware (without an underlying OS) is a nightmare. 🤣
@movq@www.uninformativ.de Yeah. I had that in my Python implementation and was really missing that.
@movq@www.uninformativ.de I see. Yeah, all the Unicode stuff certainly doesn’t help here, that’s for sure.
Maybe “speedcurses” could be a name. Or just select any Palatinate curse. ;-)
lldb or gdb 😂
@prologic@twtxt.net Oh yeah, I bet it is horrible to troubleshoot.
tt URLs View now automatically selects the first URL that I probably are going to open. In decreasing order, the URL types are:
@lyse@lyse.isobeef.org That sounds useful. 🤔
@lyse@lyse.isobeef.org I’m toying with the idea of making a widget/window system on top of Python’s ncurses. I’ve never really been happy with the existing ones (like urwid, textual, pytermgui, …). I mean, they’re not horrible, it’s mostly the performance that’s bugging me – I don’t want to wait an entire second for a terminal program to start up.
Not sure if I’ll actually see it through, though. Unicode makes this kind of thing extremely hard. 🫤
pwgen --no-capitalize --no-numerals 5 and since that already showed up in DDG search results, I simply appended the last two, which yielded nothing on DDG and Google).
@lyse@lyse.isobeef.org Bwahaha. 🤣
@lyse@lyse.isobeef.org I can tell you this right now, writing assembly / machine code is fucking hard work™ 😓 I’m sure @movq@www.uninformativ.de can affirm 🤣 And when it all goes to shit™ (which it does often), man is debugging fucking hard as hell! Without debug symbols I can’t use the regular tools like lldb or gdb 😂
@prologic@twtxt.net Yeah, the parser part is what I typically enjoy. Haven’t really looked into code generation itself.
I’m currently looking at your µ commits from the last few days. Holy cow! :-)
println(1, 2) was bring printed as 1 2 in the bytecode VM and 1 nil when natively compiled to machine code on macOS. In the end it turned out the machine code being generated / emitted meant that the list pointers for the rest... of the variadic arguments was being slot into a register that was being clobbered by the mu_retain and mu_release calls and effectively getting freed up on first use by the RC (reference counting) garbage collector 🤦♂️
@lyse@lyse.isobeef.org Yeah I remember you said some days back that your interest in compilers was rekindled by my work on mu (µ) 😅

@prologic@twtxt.net Tada, congratulations! I find that rather interesting, thanks for telling us. :-)
@movq@www.uninformativ.de How about “Quongsi”? I generated the first five letters with pwgen --no-capitalize --no-numerals 5 and since that already showed up in DDG search results, I simply appended the last two, which yielded nothing on DDG and Google).
What kind of project is it? Maybe we can help you find a name or nudge you in the right direction.
@lyse@lyse.isobeef.org True !
@prologic@twtxt.net In my opinion, the integrity isn’t lost. The same input data always result in the same output hash, no matter when you calculate the hashes. It’s true that a corrupt database contents yields to corrupt hashes, but then you have a whole bigger problem than just receiving different hashes. :-D
@zvava@twtxt.net By hashing definition, if you edit your message, it simply becomes a new message. It’s just not the same message anymore. At least from a technical point of view. As a human, personally I disagree, but that’s what I’m stuck with. There’s no reliable way to detect and “correct” for that.
Storing the hash in your database doesn’t prevent you from switching to another hashing implementation later on. As of now, message creation timestamps earlier than some magical point in time use twt hash v1, messages on or after that magical timestamp use twt hash v2. So, a message either has a v1 or a v2 hash, but not both. At least one of them is never meaningful.
Once you “upgrade” your database schema, you can check for stored messages from the future which should have been hashed using v2, but were actually v1-hashed and simply fix them.
If there will ever be another addressing scheme, you could reuse the existing hash column if it supersedes the v1/v2 hashes. Otherwise, a new column might be useful, or perhaps no column at all (looking at location-based addressing or how it was called). The old v1/v2 hashes are still needed for all past conversation trees.
In my opinion, always recalculating the hashes is a big waste of time and energy. But if it serves you well, then go for it.
@zvava@twtxt.net The problem you now then is you lose integrity of the message content if you compute the hashes at runtime rather than on the way in. So if your message content or database becomes corrupt in any way, so do your hashes.
@shinyoukai@neko.laidback.moe The CSS 404ing highlights the improvability of the content to noise ratio. :-)
@movq@www.uninformativ.de The asshats are everywhere. Luckily, it has been rather quiet so far. But of course, I now jinxed it.
@shinyoukai@neko.laidback.moe Very cool! 😎
@shinyoukai@neko.laidback.moe Nice! 👍
@movq@www.uninformativ.de Thanks! 🙏
@prologic@twtxt.net This is a really cool project, that’s for sure. 👌
@lyse@lyse.isobeef.org … I was about to write “it really is worse where you live”, then I heard the first bang out on the street. 🤣
@shinyoukai@neko.laidback.moe Nah it’s more like there’s a lot of repeated code, because when you go from source language to intermediate representation to machine code, well you just end up writing a lot of the same patterns over and over again. I need to dedupe this I think.
@kiwu@twtxt.net Ooof 😢 That’s rough!
@movq@www.uninformativ.de I’ve managed to bring a simple “Hello World!” in mu (µ) (at least on macOS / Darwin / ARM64) down to ~86KB (previously ~146KB) 🥳
@movq@www.uninformativ.de I think I can get binaries even smaller with a bit more work and effort 🤔 But yeah still working on the native code generation (at least for macOS targets)
@prologic@twtxt.net Oh! 🤔
@movq@www.uninformativ.de Oh that’s fine, Mu can compile to native code and so far binaries. at least on macOS are in the order of Kb in size 😂
@prologic@twtxt.net That might be a challenge, at least in 16-bit Real Mode: The OS follows the model of COM files on DOS, i.e. the size of the binary cannot exceed 64 KiB and heap+stack of the running program will have to fit into that same 64 KiB. 😅 (The memory layout is very rigid, each process gets such a 64 KiB slice.)
And in 64-bit Long Mode, there is no “kernel” yet. The thing in the video is literally just a small bare-metal program.
But some day, maybe. 😃
@movq@www.uninformativ.de It’d be cool if you could get µ (Mu) running in your little toyOS 🤣 You’d technically only have to swap out the syscall() builtin for whatever your toy OS supports 🤔
@thecanine@twtxt.net I see 🤔 Very cool though! 😎
@movq@www.uninformativ.de @prologic@twtxt.net Holy shit, this is sooo fucking cool! :-) Wow, I absolutely love it. It’s extremely fascinating what these optimizers do.
