@kat@yarn.girlonthemoon.xyz @prologic@twtxt.net Given that all these programs are super old (tar is from the late 1970ies), while trying to retain backwards-compatibilty, I’m not surprised that the UI isn’t too great. 🤔

find has quite a few pitfalls, that is very true. At work, we don’t even use it anymore in more complex scenarios but write Python scripts instead. find can be fast and efficient, but fewer and fewer people lack the knowledge to use it … The same goes for Shell scripting in general, actually.

VPS troubles and the weekend
This weekend I went to the cottage with P on Friday. I hoped I would
have a nice weekend reading in front of the wood stove, but I had also
planned to spend at least a few hours trying to configure Maddy as the
new mail server for hack.org et al.

Then the web server I moved to the new VPS died. Again. I connected to
the VNC console and, like before, the Linux kernel couldn’t find its
root disk. A simple:

PATH isn’t real on Linux
I have no idea how much relevance this short but informative rundown of how PATH works in Linux has in the real world, but I found it incredibly interesting and enlightening. The basic gist – and I might be wrong, there’s code involved and I’m not very smart – is that Linux itself needs absolute paths to binaries, while shells and programming languages do not. In other words, the Linux kernel does not know about PATH, and any lookup you’re doing comes from either the shell or the pr … ⌘ Read more

Can you automate the drawing with a script? On X11, you can:

# Position the pointer at the center of the dot, then run this script.

sleep 1

start=$(xdotool getmouselocation --shell)
eval $start

r=400
steps=100
down=0

for step in $(seq $((steps + 1)) )
do
    # pi = 4 * atan(1)
    new_x=$(printf '%s + %s * c(%s / %s * 2 * (4 * a(1)))\n' $X $r $step $steps | bc -l)
    new_y=$(printf '%s + %s * s(%s / %s * 2 * (4 * a(1)))\n' $Y $r $step $steps | bc -l)

    xte "mousemove ${new_x%%.*} ${new_y%%.*}"
    if ! (( down ))
    then
        xte 'mousedown 1'
        down=1
    fi
done

xte 'mouseup 1'
xte "mousemove $X $Y"

Interestingly, you can abuse the scoring system (not manually, only with a script). Since the mouse jumps to the locations along the circle, you can just use very few steps and still get a great score because every step you make is very accurate – but the result looks funny:

@prologic@twtxt.net I think printf is a more portable option than echo -e for interpreting \t as tab. E.g. printf ‘%s\t%s\t%s’ “$url” “$time” “$text”.

Diving into mblaze, I think I’ve nearly* reached peek email geek.

Just a bunch of shell commands I can pipe together to search, list, view and reply to email (after syncing it to a local Maildir).

EXAMPLES at https://git.vuxu.org/mblaze/tree/README

So far I’m using most of the tools directly from the command line, but I might take inspiration from https://sr.ht/~rakoo/omail/ to make my workflow a bit more efficient.

*To get any closer, I think I’d have to hand-craft my own SMTP client or something.

@prologic@twtxt.net Thanks for writing that up!

I hope it can remain a living document (or sequence of draft revisions) for a good long time while we figure out how this stuff works in practice.

I am not sure how I feel about all this being done at once, vs. letting conventions arise.

For example, even today I could reply to twt abc1234 with “(#abc1234) Edit: …” and I think all you humans would understand it as an edit to (#abc1234). Maybe eventually it would become a common enough convention that clients would start to support it explicitly.

Similarly we could just start using 11-digit hashes. We should iron out whether it’s sha256 or whatever but there’s no need get all the other stuff right at the same time.

I have similar thoughts about how some users could try out location-based replies in a backward-compatible way (append the replyto: stuff after the legacy (#hash) style).

However I recognize that I’m not the one implementing this stuff, and it’s less work to just have everything determined up front.

Misc comments (I haven’t read the whole thing):

• Did you mean to make hashes hexadecimal? You lose 11 bits that way compared to base32. I’d suggest gaining 11 bits with base64 instead.

• “Clients MUST preserve the original hash” — do you mean they MUST preserve the original twt?

• Thanks for phrasing the bit about deletions so neutrally.

• I don’t like the MUST in “Clients MUST follow the chain of reply-to references…”. If someone writes a client as a 40-line shell script that requires the user to piece together the threading themselves, IMO we shouldn’t declare the client non-conforming just because they didn’t get to all the bells and whistles.

• Similarly I don’t like the MUST for user agents. For one thing, you might want to fetch a feed without revealing your identty. Also, it raises the bar for a minimal implementation (I’m again thinking again of the 40-line shell script).

• For “who follows” lists: why must the long, random tokens be only valid for a limited time? Do you have a scenario in mind where they could leak?

• Why can’t feeds be served over HTTP/1.0? Again, thinking about simple software. I recently tried implementing HTTP/1.1 and it wasn’t too bad, but 1.0 would have been slightly simpler.

• Why get into the nitty-gritty about caching headers? This seems like generic advice for HTTP servers and clients.

• I’m a little sad about other protocols being not recommended.

• I don’t know how I feel about including markdown. I don’t mind too much that yarn users emit twts full of markdown, but I’m more of a plain text kind of person. Also it adds to the length. I wonder if putting a separate document would make more sense; that would also help with the length.

@movq@www.uninformativ.de I don’t know if I’d want to discard the twts. I think what I’m looking for is a command “jenny -g https://host.org/twtxt.txt” to fetch just that one feed, even if it’s not in my follow list. I could wrap that in a shell script so that when I see a twt in reply to a feed I don’t follow, I can just tap a key and the feed will get added to my maildir. I guess the script would look for a mention at the start of a selected twt and call jenny -g on the feed.

It looks like there’s a podman issue for adding the context subcommand that docker has. Currently podman does not have this subcommand, although this comment has a translation to podman commands that are similar-ish.

It looks like that’s all you need to do to support podman right now! Though I’m not 100% sure the containers I tried really are running remotely. Details below.

I manually edited the shell script that cas.run add returns, changing all the docker commands to podman commands. Specifically, I put alias docker=podman at the top so the check for docker would pass, and then I replaced the last two lines of the script with these:

podman system connection add cas  "host=tcp://cas.run..."
podman system connection default cas

(that … after cas.run is a bunch of connection-specific stuff)

I ran the script and it exited with no output. It did create a connection named “cas”, and made that the default. I’m not super steeped in how podman works but I believe that’s what you need to do to get podman to run containers remotely.

I ran some containers using podman and I think they are running remotely but I don’t know the right juju to verify. It looks right though!

This means you could probably make minor modifications to the generated shell script to support podman. Maybe when the check for docker fails, check for podman, and then later in the script use the podman equivalents to the docker context commands.
