@bender@twtxt.net yeah, I’ve been reading through the documentation last night and it felt overwhelming for a minute… +1 point goes to GTS’s docs. but hey, I’ll be taking the easy route: podman-compose up -d they provide both a container image and an example compose file in a separate git repo but I’m wondering why that is not mentioned anywhere in the docs, (unless it is and I haven’t seen it yet)

@prologic@twtxt.net I am telling you that is extremely easy: https://docs.gotosocial.org/en/latest/advanced/host-account-domain/. Now, if you are putting into account your rather… unique setup, then that’s another story.

@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.

FTR, I see one (two) issues with PyQt6, sadly:

1. The PyQt6 docs appear to be mostly auto-generated from the C++ docs. And they contain many errors or broken examples (due to the auto-conversion). I found this relatively unpleasent to work with.
   
2. (Until Python finally gets rid of the Global Interpreter Lock properly, it’s not really suited for GUI programs anyway – in my opinion. You can’t offload anything to a second thread, because the whole program is still single-threaded. This would have made my fractal rendering program impossible, for example.)

I used Gemini (the Google AI) twice at work today, asking about Google Workspace configuration and Google Cloud CLI usage (because we use those a lot). You’d think that it’d be well-suited for those topics. It answered very confidently, yet completely wrong. Just wrong. Made-up CLI arguments, whatever. It took me a while to notice, though, because it’s so convincing and, well, you implicitly and subconsciously trust the results of the Google AI when asking about Google topics, don’t you?

Will it get better over time? Maybe. But what I really want is this:

• Good, well-structured, easy-to-read, proper documentation. Google isn’t doing too bad in this regard, actually, it’s just that they have so much stuff that it’s hard to find what you’re looking for. Hence …
  
• … I want a good search function. Just give me a good fuzzy search for your docs. That’s it.
  

I just don’t have the time or energy to constantly second-guess this stuff. Give me something reliable. Something that is designed to do the right thing, not toy around with probabilities. “AI for everything” is just the wrong approach.

I can’t disable a bloody loud beep from my Lenovo laptop “keyboard panic, you can’t type right now”. Online docs mention a UEFI setting that is just not there.This 💩 makes me so angry.

@movq@www.uninformativ.de Yeah, give it a shot. At worst you know that you have to continue your quest. :-)

Fun fact, during a semester break I was actually a little bored, so I just started reading the Qt documentation. I didn’t plan on using Qt for anything, though. I only looked at the docs because they were on my bucket list for some reason. Qt was probably recommended to me and coming from KDE myself, that was motivation enough to look at the docs just for fun.

The more I read, the more hooked I got. The documentation was extremely well written, something I’ve never seen before. The structure was very well thought out and I got the impression that I understood what the people thought when they actually designed Qt.

A few days in I decided to actually give it a real try. Having never done anything in C++ before, I quickly realized that this endeavor won’t succeed. I simply couldn’t get it going. But I found the Qt bindings for Python, so that was a new boost. And quickly after, I discovered that there were even KDE bindings for Python in my package manager, so I immediately switched to them as that integrated into my KDE desktop even nicer.

I used the Python KDE bindings for one larger project, a planning software for a summer camp that we used several years. It’s main feature was to see who is available to do an activity. In the past, that was done on a large sheet of paper, but people got assigned two activities at the same time or weren’t assigned at all. So, by showing people in yellow (free), green (one activity assigned) and red (overbooked), this sped up and improved the planning process.

Another core feature was to generate personalized time tables (just like back in school) and a dedicated view for the morning meeting on site.

It was extended over the years with all sorts of stuff. E.g. I then implemented a warning if all the custodians of an activitiy with kids were underage to satisfy new the guidelines that there should be somebody of age.

Just before the pandemic I started to even add support for personalized live views on phones or tablets during the planning process (with web sockets, though). This way, people could see their own schedule or independently check at which day an activity takes place etc. For these side quests, they don’t have to check the large matrix on the projector. But the project died there.

Here’s a screenshot from one of the main views: https://lyse.isobeef.org/tmp/k3man.png

This Python+Qt rewrite replaced and improved the Java+Swing predecessor.

Actually. Looking at the template and the BeerCSS docs, I think I’m just using the wrong elements and doing the wrong thing in the template/partial structure itself 🤔 Probably need to wrap text in something else other than a plain ‘ol <p>

@prologic@twtxt.net No, this is a Linux manpage from the man-pages project: https://git.kernel.org/pub/scm/docs/man-pages/man-pages.git/tree/man/man7/ascii.7

Dear dev.alessandrocutolo.it, do you really need to fetch my twtxt feed every 20-30 seconds? 😅 Not that it’s posing a problem, but I feel like this could be optimized. For example, how about using the if-modified-since request header: https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/If-Modified-Since

Ah, so apparently they don’t like writing manpages anymore and instead use XML:

And then they use XSLT on top and what not:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/manpage-style.xsl.cmake.in

Abstractions upon abstractions upon abstractions.

Look at that, a mate just told me: What if YAML had even more security issues!? YAMLScript! https://yamlscript.org/doc/cheat/

Here’s an example of X11/Xlib being old and archaic.

X11 knows the data type “cardinal”. For example, the window property _NET_WM_ICON (which holds image data for icons) is an array of “cardinal”. I am already not really familiar with that word and I’m assuming that it comes from mathematics:

https://en.wikipedia.org/wiki/Cardinal_number

(It could also be a bird, but probably not: https://en.wikipedia.org/wiki/Cardinalidae)

We would probably call this an “integer” today.

EWMH says that icons are arrays of cardinals and that they’re 32-bit numbers:

https://specifications.freedesktop.org/wm-spec/latest-single/#id-1.6.13

So it’s something like 0x11223344 with 0x11 being the alpha channel, 0x22 is red, and so on.

You would assume that, when you retrieve such an array from the X11 server, you’d get an array of uint32_t, right?

Nope.

Xlib is so old, they use char for 8-bit stuff, short int for 16-bit, and long int for 32-bit:

https://x.org/releases/current/doc/libX11/libX11/libX11.html#Obtaining_and_Changing_Window_Properties

That is congruent with the general C data types, so it does make sense:

https://en.wikipedia.org/wiki/C_data_types

Now the funny thing is, on modern x86_64, the type long int is actually 64 bits wide.

The result is that every pixel in a Pixmap, for example, is twice as large in memory as it would need to be. Just because Xlib uses long int, because uint32_t didn’t exist, yet.

And this is something that I wouldn’t know how to fix without breaking clients.

@lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz I spent so much time in the past figuring out if something is a dict or a list in YAML, for example.

What are the types in this example?

items:
- part_no:   A4786
  descrip:   Water Bucket (Filled)
  price:     1.47
  quantity:  4
- part_no:   E1628
  descrip:   High Heeled "Ruby" Slippers
  size:      8
  price:     133.7
  quantity:  1

items is a dict containing … a list of two other dicts? Right?

It is quite hard for me to grasp the structure of YAML docs. 😢

The big advantage of YAML (and JSON and TOML) is that it’s much easier to write code for those formats, than it is with XML. json.loads() and you’re done.

After many weeks and probably at least a hundred hours of research, discussions and in-person viewing, I think I’ve finally come up with my Final Choices (shortlist) of a Hybrid Camper / Caravan that I think will suit my family and that I’ll enjoy (far less work for me to setup and teardown).

HTTP referrers are quite broken, aren’t they?

Because of that recent storm on my blog, I had a peek at them. There’s a lot of garbage in there. For example, https://docs.freebsd.org/en/books/handbook/disks-virtual.html is supposed to refer to one of my blog posts …

What’s going on here?

Been spending a lot of time researching campers as I want to / plan to upgrade our current Camper Trailoer (forward fold) Stoney Creek XL-FF6 to a slightly larger Hybrid Camper/Caravan with ensuite, internal kitchenette, external full hitchen, pop-top roof and twin bunks.

This is the summary and whittling down of my research so far: https://wiki.mills.io/s/1103bc9c-dd75-4a98-b64b-8dadc5b0e51f/doc/comparision-Ln03Moiibq

I did a “lecture”/“workshop” about this at work today. 16-bit DOS, real mode. 💾 Pretty cool and the audience (devs and sysadmins) seemed quite interested. 🥳

• People used the Intel docs to figure out the instruction encodings.
  
• Then they wrote a little DOS program that exits with a return code and they used uhex in DOSBox to do that. Yes, we wrote a COM file manually, no Assembler involved. (Many of them had never used DOS before.)
  
• DEBUG from FreeDOS was used to single-step through the program, showing what it does.
  
• This gets tedious rather quickly, so we switched to SVED from SvarDOS for writing the rest of the program in Assembly language. nasm worked great for us.
  
• At the end, we switched to BIOS calls instead of DOS syscalls to demonstrate that the same binary COM file works on another OS. Also a good opportunity to talk about bootloaders a little bit.
  
• (I think they even understood the basics of segmentation in the end.)
  

The 8086 / 16-bit real-mode DOS is a great platform to explain a lot of the fundamentals without having to deal with OS semantics or executable file formats.

Now that was a lot of fun. 🥳 It’s very rare that we do something like this, sadly. I love doing this kind of low-level stuff.

Okay, here’s a thing I like about Rust: Returning things as Option and error handling. (Or the more complex Result, but it’s easier to explain with Option.)

fn mydiv(num: f64, denom: f64) -> Option<f64> {
    // (Let’s ignore precision issues for a second.)
    if denom == 0.0 {
        return None;
    } else {
        return Some(num / denom);
    }
}

fn main() {
    // Explicit, verbose version:
    let num: f64 = 123.0;
    let denom: f64 = 456.0;
    let wrapped_res = mydiv(num, denom);
    if wrapped_res.is_some() {
        println!("Unwrapped result: {}", wrapped_res.unwrap());
    }

    // Shorter version using "if let":
    if let Some(res) = mydiv(123.0, 456.0) {
        println!("Here’s a result: {}", res);
    }

    if let Some(res) = mydiv(123.0, 0.0) {
        println!("Huh, we divided by zero? This never happens. {}", res);
    }
}

You can’t divide by zero, so the function returns an “error” in that case. (Option isn’t really used for errors, IIUC, but the basic idea is the same for Result.)

Option is an enum. It can have the value Some or None. In the case of Some, you can attach additional data to the enum. In this case, we are attaching a floating point value.

The caller then has to decide: Is the value None or Some? Did the function succeed or not? If it is Some, the caller can do .unwrap() on this enum to get the inner value (the floating point value). If you do .unwrap() on a None value, the program will panic and die.

The if let version using destructuring is much shorter and, once you got used to it, actually quite nice.

Now the trick is that you must somehow handle these two cases. You must either call something like .unwrap() or do destructuring or something, otherwise you can’t access the attached value at all. As I understand it, it is impossible to just completely ignore error cases. And the compiler enforces it.

(In case of Result, the compiler would warn you if you ignore the return value entirely. So something like doing write() and then ignoring the return value would be caught as well.)

@prologic@twtxt.net I’m trying to call some libc functions (because the Rust stdlib does not have an equivalent for getpeername(), for example, so I don’t have a choice), so I have to do some FFI stuff and deal with raw pointers and all that, which is very gnarly in Rust – because you’re not supposed to do this. Things like that are trivial in C or even Assembler, but I have not yet understood what Rust does under the hood. How and when does it allocate or free memory … is the pointer that I get even still valid by the time I do the libc call? Stuff like that.

I hope that I eventually learn this over time … but I get slapped in the face at every step. It’s very frustrating and I’m always this 🤏 close to giving up (only to try again a year later).

Oh, yeah, yeah, I guess I could “just” use some 3rd party library for this. socket2 gets mentioned a lot in this context. But I don’t want to. I literally need one getpeername() call during the lifetime of my program, I don’t even do the socket(), bind(), listen(), accept() dance, I already have a fully functional file descriptor. Using a library for that is total overkill and I’d rather do it myself. (And look at the version number: 0.5.10. The library is 6 years old but they’re still saying: “Nah, we’re not 1.0 yet, we reserve the right to make breaking changes with every new release.” So many Rust libs are still unstable …)

… and I could go on and on and on … 🤣

fn sub(foo: &String) {
    println!("We got this string: [{}]", foo);
}

fn main() {
    // "Hello", 0x00, 0x00, "!"
    let buf: [u8; 8] = [0x48, 0x65, 0x6C, 0x6C, 0x6F, 0x00, 0x00, 0x21];

    // Create a string from the byte array above, interpret as UTF-8, ignore decoding errors.
    let lossy_unicode = String::from_utf8_lossy(&buf).to_string();

    sub(&lossy_unicode);
}

Create a string from a byte array, but the result isn’t a string, it’s a cow 🐮, so you need another to_string() to convert your “string” into a string.

• https://doc.rust-lang.org/std/string/struct.String.html#method.from_utf8_lossy
  
• https://doc.rust-lang.org/std/borrow/enum.Cow.html
  

I still have a lot to learn.

(into_owned() instead of to_string() also works and makes more sense to me, it’s just that the compiler suggested to_string() first, which led to this funny example.)

@lyse@lyse.isobeef.org Rust is so different and, at the same time, so complex – it’s not far fetched to assume that I simply don’t understand what’s going on here. The docs appear to be clear, but alas … is it a bugs in the docs? Is it a lack of experience on my part? Who knows.

By the way, looks like there was a bit of a discussion regarding that name:

https://github.com/rust-lang/rust/issues/120048

So I was using this function in Rust:

https://doc.rust-lang.org/std/path/struct.Path.html#method.display

Note the little 1.0.0 in the top right corner, which means that this function has been “stable since Rust version 1.0.0”. We’re at 1.87 now, so we’re good.

Then I compiled my program on OpenBSD with Rust 1.86, i.e. just one version behind, but well ahead of 1.0.0.

The compiler said that I was using an unstable library feature.

Turns out, that function internally uses this:

https://doc.rust-lang.org/std/ffi/struct.OsStr.html#method.display

And that is only available since Rust 1.87.

How was I supposed to know this? 🤨🫩

@prologic@twtxt.net Yeah, it’s difficult, you often don’t get what you’d expect. They also make heavy use of 3rd party libraries. IIUC, for random numbers, they refer to this library. I’ve read many times that the Rust stdlib is intentionally minimalistic (to make it easier to maintain and port and all that).

I’m struggling with this, using 3rd party libs for so many things isn’t really my cup of tea. I’ll probably make my own tiny little “standard library”. It’s silly, but I don’t see any other options. 🤷

@movq@www.uninformativ.de @kat@yarn.girlonthemoon.xyz @quark@ferengi.one In 2014 one person created protocol ii. Later it forked in IDEC. Why i said this? Because it’s simple “federated” forum-like protocol where from your station fetch another every 5-10 minutes. Stations has topic-based channels like idec.talks, linux.16, haiku.os, zx.spectrum. In short it’s FIDO but.. more modern? Documentation: https://github.com/idec-net/new-docs (mostly Russian, but you can use translator, also protocol already translated to english)

Confession:

I’ve never found microblogging like twtxt or the Fediverse or any other “modern” social media to be truly fulfilling/satisfying.

The reason is that it is focused so much on people. You follow this or that person, everybody spends time making a nice profile page, the posts are all very “ego-centric”. Seriously, it feels like everybody is on an ego-trip all the time (this is much worse on the Fediverse, not so much here on twtxt).

I miss the days of topic-based forums/groups. A Linux forum here, a forum about programming there, another one about a certain game. Stuff like that. That was really great – and it didn’t even suffer from the need to federate.

Sadly, most of these forums are dead now. Especially the nerds spend a lot of time on the Fediverse now and have abandoned forums almost completely.

On Mastodon, you can follow hashtags, which somewhat emulates a topic-based experience. But it’s not that great and the protocol isn’t meant to be used that way (just read the snac2 docs on this issue). And the concept of “likes” has eliminated lots of the actual user interaction. ☹️

I want to propose my own counter-proposal to the discussion that’s ongoing with Go and error handling.

@bender@twtxt.net oh yeah i remember that part of the docs lol! honestly yeah i think sqlite is fine for the number of users i have which is like, 5 including me, and active users is just… me, but if i were to have more active users i could always spin up a separate instance as jank as that is

The fact that the official Python docs don’t clearly state what a function returns, grinds my gears. This has cost me so much time over the years. You always have to read through a huge block of text.

You could at least put a list of possible return values in there (always at the same location, please!), here’s a mockup:

asciinema is really cool. thought about self hosting my own upload site which they have docs for but i don’t need to host everything even if it’d be a fun project. the default/main site is fine enough for me when i won’t be uploading a whole lot.

@eapl.me@eapl.me A way to have a more bluesky’ish handles in twtxt could be to take inspiration from Bridgy Fed and say: If NICK = DOMAIN then only show @DOMAIN
So instead of @eapl.me@eapl.me it will just be @eapl.me

Okay folks, I’ve spent all day on this today, and I think its in “good enough”™ shape to share:

Twtxt v2:

• Specification: https://docs.mills.io/uJXuisaYTRWYDrl8A2jADg?both
  
• implementation: https://gist.mills.io/prologic/afdec15443da4d7aa898f383f171ec1b
  

LOl 😂 Not only have a tried to write up a full Twtxt v2 specification, I’ve also written a Bash shell script that implements the new spec 😅

@quark@ferengi.one It looks like the part about traditional topics has been removed from that page. Here is an old version that mentions it: https://web.archive.org/web/20221211165458/https://dev.twtxt.net/doc/twtsubjectextension.html . Still, I don’t see any description of what is actually allowed between the parentheses. May be worth noting that twtxt.net is displaying the twts with the subject stripped, so some piece of code is recognizing it as a subject (or, at least, something to be removed).

@falsifian@www.falsifian.org based on Twt Subject Extension, your subject is invalid. You can have custom subjects, that is, not a valid hash, but you simply can’t put anything, and expect it to be treated as a TwtSubject, me thinks.

@mckinley@twtxt.net

HTTPS is supposed to do [verification] anyway.

TLS provides verification that nobody is tampering with or snooping on your connection to a server. It doesn’t, for example, verify that a file downloaded from server A is from the same entity as the one from server B.

I was confused by this response for a while, but now I think I understand what you’re getting at. You are pointing out that with signed feeds, I can verify the authenticity of a feed without accessing the original server, whereas with HTTPS I can’t verify a feed unless I download it myself from the origin server. Is that right?

I.e. if the HTTPS origin server is online and I don’t mind taking the time and bandwidth to contact it, then perhaps signed feeds offer no advantage, but if the origin server might not be online, or I want to download a big archive of lots of feeds at once without contacting each server individually, then I need signed feeds.

feed locations [being] URLs gives some flexibility

It does give flexibility, but perhaps we should have made them URIs instead for even more flexibility. Then, you could use a tag URI, urn:uuid:*, or a regular old URL if you wanted to. The spec seems to indicate that the url tag should be a working URL that clients can use to find a copy of the feed, optionally at multiple locations. I’m not very familiar with IP{F,N}S but if it ensures you own an identifier forever and that identifier points to a current copy of your feed, it could be a great way to fix it on an individual basis without breaking any specs :)

I’m also not very familiar with IPFS or IPNS.

I haven’t been following the other twts about signatures carefully. I just hope whatever you smart people come up with will be backwards-compatible so it still works if I’m too lazy to change how I publish my feed :-)

@bender@twtxt.net Yes, they do 🤣 Implicitly, or threading would never work at all 😅 Nor lookups 🤣 They are used as keys. Think of them like a primary key in a database or index. I totally get where you’re coming from, but there are trade-offs with using Message/Thread Ids as opposed to Content Addressing (like we do) and I believe we would just encounter other problems by doing so.

My money is on extending the Twt Subject extension to support more (optional) advanced “subjects”; i.e: indicating you edited a Twt you already published in your feed as @falsifian@www.falsifian.org indicated 👌

Then we have a secondary (bure much rarer) problem of the “identity” of a feed in the first place. Using the URL you fetch the feed from as @lyse@lyse.isobeef.org ’s client tt seems to do or using the # url = metadata field as every other client does (according to the spec) is problematic when you decide to change where you host your feed. In fact the spec says:

Users are advised to not change the first one of their urls. If they move their feed to a new URL, they should add this new URL as a new url field.

See Choosing the Feed URL – This is one of our longest debates and challenges, and I think (_I suspect along with @xuu@txt.sour.is _) that the right way to solve this is to use public/private key(s) where you actually have a public key fingerprint as your feed’s unique identity that never changes.

I just manually followed the steps at https://dev.twtxt.net/doc/twthashextension.html and got 6mdqxrq. I wonder what happened. Did @cuaxolo@sunshinegardens.org edit the twt in some subtle way after twtxt.net downloaded it? I couldn’t spot a diff, other than ‘ appearing as ’ on yarn.social, which I assume is a transformation done by twtxt.net.

@prologic@twtxt.net Yes, fetching the twt by hash from some service could be a good alternative, in case the twt I have does not @-mention the source. (Besides yarnd, maybe this should be part of the registry API? I don’t see fetch-by-hash in the registry API docs.)

Hey @sorenpeter@darch.dk, I’m sorry to tell you, but the prev field in your feed’s headers is invalid. 😅

First, it doesn’t include the hash of the last twt in the archive. Second, and that’s probably more important, it forms an infinite loop: The prev field of your main feed specifies http://darch.dk/twtxt-archive.txt and that file then again specifies http://darch.dk/twtxt-archive.txt. Some clients might choke on this, mine for example. 😂 I’ll push a fix soon, though.

For reference, the prev field is described here: https://dev.twtxt.net/doc/archivefeedsextension.html
