↳ In-reply-to » @lyse A "Hello World" binary is ~372KB in size. I currently have peephole optimization and deac code optimizations in play, and a few other performance related ones, but nothing too fancy. I have a test case that ensures fib(35) doesn't regress too badly as I continue to evolve the language.

@prologic@twtxt.net Not bad for a start, ey! Looking forward to see you going down these rabbit holes and opening one can of worms after the other. :ā€˜-D Very, very impressive, hats off to you. :-)

↳ In-reply-to » The original twt is unavailable. It may have been edited or deleted, or is from an unknown or muted feed.

@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.

↳ In-reply-to » Hmm, mine also resolves a leading tilde in these variables. And if $HOME is not specified it tries to resolve the user's home directory by user.Current().HomeDir. Maybe that's overkill, I have to check the XDG spec.

Ok, the standard library implementation is wonky at best, at least in regards to XDG, because it really doesn’t implement it properly. https://github.com/golang/go/issues/62382 I stick to my own code then. It doesn’t properly support anything else than Linux or Unixes that use XDG, but personally, I don’t care about them anyway. And the cross-platform situation is a giant mess. Unsurprisingly.

↳ In-reply-to » @lyse Well, I used SnipMate years ago (until 2012). IIRC, it’s more than just ā€œinsert a bit of text hereā€, it can also jump to the correct next location(s) and stuff like that. Don’t remember why I stopped using it.

@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.

The tt URLs View now automatically selects the first URL that I probably are going to open. In decreasing order, the URL types are:

  1. markdown media URLs (images, videos, etc.)
  2. markdown or plaintext URLs
  3. subjects
  4. mentions

I might differentiate between mentions of subscribed and unsubscribed feeds in the future. The odds of opening a new feed over an already existing one are higher.

↳ In-reply-to » @lyse while caching those is a good idea the problem is baking data that can be calculated into the database instead of some cache, because post hashes are not fixed and change for every post edit. you can always easily look up other twts by hash with a cached lookup table, but now you're not locked into them so supporting hashv2 or other hash variants or any other solution becomes far easier

@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 ā€œcorrectā€ 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 ā€œupgradeā€ 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.

@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.

@prologic@twtxt.net Not even entirely sure how I did it myself, but likely a lucky combination of the new tail swirl, the legs closer to the screen being bigger and the head looking slightly to the side (eye & ear position), with bottom part of the hair, going behind the snout. The white is just an outline, around most of my works, so I don’t think that plays a part.

↳ In-reply-to » @movq wow! what is assembler?

@kiwu@twtxt.net Assembly is usually the most low-level programming language that you can get. Typical programming languages like Python or Go are a thick layer of abstraction over what the CPU actually does, but with Assembler you get to see it all and you get full control. (With lots of caveats and footnotes. šŸ˜…)

I’m interested in the boot process, i.e. what exactly happens when you turn on your computer. In that area, using Assembler is a must, because you really need that fine-grained control here.

@lyse@lyse.isobeef.org no wonder I picked that cake (albeit coincidentally), I adore almonds, and hazelnuts! Your teammates are absolutely amazing, dude! A very nice project farewell! On leaving places I have a small anecdote.

I know someone who on 3 February 2004 left his job to go elsewhere. At the time his teammates threw a party, and gave him a very nice portable storage. Twenty days later, he returned, and jokingly they asked him for the storage, and money spent on farewell party back. I heard, from a close source, that he gave them his middle finger, but don’t quote me on that. šŸ˜‚šŸ˜‚šŸ˜‚

Thinking about doing Advent of Code in my own tiny language mu this year.

mu is:

  • Dynamically typed
  • Lexically scoped with closures
  • Has a Go-like curly-brace syntax
  • Built around lists, maps, and first-class functions

Key syntax:

  • Functions use fn and braces:
fn add(a, b) {
    return a + b
}
  • Variables use := for declaration and = for assignment:
x := 10
x = x + 1
  • Control flow includes if / else and while:
if x > 5 {
    println("big")
} else {
    println("small")
}
while x < 10 {
    x = x + 1
}
  • Lists and maps:
nums := [1, 2, 3]
nums[1] = 42
ages := {"alice": 30, "bob": 25}
ages["bob"] = ages["bob"] + 1

Supported types:

  • int
  • bool
  • string
  • list
  • map
  • fn
  • nil

mu feels like a tiny little Go-ish, Python-ish language — curious to see how far I can get with it for Advent of Code this year. šŸŽ„

↳ In-reply-to » I have a question! I'm looking for a small personal camera(specifically good for videos because that's what I'll use it for) that's cheap enough for a teen to afford but also actually good. Do any of you tech people have any good recs?

@kiwu@twtxt.net It also greatly depends on what kind of videos you plan to record. When you go, let’s say, diving, the specs need to be probably more suited to that type of environment. What about zoom, macro shots, wide landscapes, and so on? When typically mounted on a tripod, I’d say builtin image stabilization is not required, but for more action shots, this is fairly important to not get sea sick. :-)

I’ve got a Nikon Coolpix S9300. I typically only take photos, but it also works for the occasional video. Free hand moves are quite difficult, but when mounted to a tripod, this is not too shabby. There’s absolutely no way around a (makeshift) tridpod when zooming in, though. The audio is definitely not the best, especially wind destroys everything. If I recorded more video, I would certainly want to have an external microphone.

↳ In-reply-to » @prologic I'd say give crowdsec a try but I know for sure you prefer your own WAF ... šŸ˜…

@prologic@twtxt.net The main thing that I tought of is that whomever is abusing your services must be a well known actor (by range/set of IPs) that got reported by other Crowdsec users. So to my simpleton’s understanding, your reverse-proxy/web server passes the requests by crowdsec for processing, they get banned for $N hours if the source has already been blacklisted by the community or violates any of a set of behavior base rules (and even more hours for repeat offenders); otherwise the requests/responses go as per usual. Not sure if I got things right but this might help paint a better picture of the process.

↳ In-reply-to » Hmmm 🧐 I'm annectodaly not convinced so-called "AI"(s) really save timeā„¢. -- I have no proof though, I would need to do some concrete studies / numbers... -- But, there is one benefit... It can save you from typing and from worsening RSI / Carpal Tunnel.

@prologic@twtxt.net AI is slot machines for coders:

The same intermittent reward operant conditioning that gets people addicted to gambling and thinking that if they follow certain rituals they’ll win ā€œnext timeā€ drives people’s beliefs that AI tools are making them more productive when they’re making them less productive. I’m going to guess that a side effect of this is that people think they’re typing less when in the longer term they’re typing the same amount or more when you factor in the productivity loss (as far as I’ve read the studies don’t measure this so I’m only guessing).

People are also being rapidly de-skilled by this technology: the more they use it, the more their actual skills atrophy. ā€œContinuous exposure to AI might reduce the ADR (adesoma detection rate) of standard non-AI assisted colonoscopy, suggesting a negative effect on endoscopist behaviour.ā€ (science speak for saying that radiologists get worse at seeing tumors in scans once they’ve used AI): https://www.thelancet.com/journals/langas/article/PIIS2468-1253(25)00133-5/abstract

Nobody who cares about the future should be using this stuff for anything.
