demander à perplexity quelle est la meilleure matière scientifique, et lire que c’est incontestablement la matière que j’enseigne, ça me fait jubiler d’avance pour embêter mes collègues XD

Ouiii, j’ai de nouveau internet! En fait, #sfr a changé l’armoire, a débranché tout le monde sans prévenir personne, et maintenant les autres fournisseurs doivent venir rebrancher leurs clients. C’est malhonnête… Bref, si3t.ch et puffy.cafe sont de retour

@movq@www.uninformativ.de Yeah, the Swiss and C++ programmers use apostrophes. :-) My grandpa had an electronic desk calculator that also used some kind of apostrophes as the thousands separator on its cool display. Maybe it consisted of Nixie tubes, can’t remember anymore.

I think non-breaking spaces are preferred nowadays to avoid the confusion.

Went on a really cool walk today after the sun came out this arvo. Just 11°C and a fair bit of wind required a scarf and beanie. I love the autumn colors a lot and never tire of looking at them.

On the summit the view was absolutely terrible, because there were super low hanging clouds. But it still looked fairly spectacular. Very surreal, I could not make out the edge of the Swabian Alb. The haze just blended with the rest of the sky. Towards the sun it was just one giant white wall after half a kilometer or so. That doesn’t happen all that often here.

After dusk I saw five deer on a meadow. Well their outlines against the remaining backlit sky.

@prologic@twtxt.net that’s still a generalization. which religion, which historical trends, which extremes, &c. otherwise you aren’t actually saying anything about religion, you’re expressing disapproval of extremes. which is valid, but doesn’t make for a substantial critique, if that makes sense.

*PSHHHHT. Vous avez entendu? C’est le son de la boisson houblonée pour me féliciter d’avoir terminé la correction de mes paquets de copies haut comme l’avant bras la veille des #utopiales2024. Yeah!

the test would be: how often does unwanted content get pushed on your feed? do incongruent posters easily disrupt harmonious connections? &c. less about the community, more about how the social dynamics play out as various groups and individuals interact.

mon niveau serait de 13-kyu, je ne sais pas si c’est bien :/ https://play.baduk.org/go-test/start.php?

@prologic@twtxt.net Sure!! gg=G auto-indents your documents, as for the rest it’s:

• v for selection mode, c for change and d for delete actions as usual.
  
• followed by either ‘afor around ori` for inside/in-between whatever special character comes after it
  _ the [, (, “ … special characters define the perimeter/extent of the action.
  

i.e: ci" would be change the text under the cursor between quotes and da[ _delete text and brackets included_

I’ve linked a reference in the first twt, hope you find it useful.

How, this is some funny easter egg: https://git.savannah.nongnu.org/cgit/man-db.git/commit/src/man.c?id=002a6339b1fe8f83f4808022a17e1aa379756d99

@prologic@twtxt.net Regarding the new way of generating twt-hashes, to me it makes more sense to use tabs as separator instead of spaces, since the you can just copy/past a line directly from a twtxt-file that already go a tab between timestamp and message. But tabs might be hard to “type” when you are in a terminal, since it will activate autocomplete…🤔

Another thing, it seems that you sugget we only use the domain in the hash-creation and not the full path to the twtxt.txt

$ echo -e "https://example.com 2024-09-29T13:30:00Z Hello World!" | sha256sum - | awk '{ print $1 }' | base64 | head -c 12

Aujourd’hui, petits changements de formatage de mes documents sur le style RFC. Le titre apparaît désormais au centre et en haut de page. On a aussi la date de rédaction suivie de la date de dernière mise à jour. Que c’est beau :)

Gemini/Gopher Twtxt feeds account for less than 1% in existence:

4 gopher: 0.38%
1046 http/https: 98.96%

@aelaraji@aelaraji.com This is one of the reasons why yarnd has a couple of settings with some sensible/sane defaults:

I could already imagine a couple of extreme cases where, somewhere, in this peaceful world one’s exercise of freedom of speech could get them in Real trouble (if not danger) if found out, it wouldn’t necessarily have to involve something to do with Law or legal authorities. So, If someone asks, and maybe fearing fearing for… let’s just say ‘Their well being’, would it heart if a pod just purged their content if it’s serving it publicly (maybe relay the info to other pods) and call it a day? It doesn’t have to be about some law/convention somewhere … 🤷 I know! Too extreme, but I’ve seen news of people who’d gone to jail or got their lives ruined for as little as a silly joke. And it doesn’t even have to be about any of this.

There are two settings:

$ ./yarnd --help 2>&1 | grep max-cache
      --max-cache-fetchers int        set maximum numnber of fetchers to use for feed cache updates (default 10)
  -I, --max-cache-items int           maximum cache items (per feed source) of cached twts in memory (default 150)
  -C, --max-cache-ttl duration        maximum cache ttl (time-to-live) of cached twts in memory (default 336h0m0s)

So yarnd pods by default are designed to only keep Twts around publicly visible on either the anonymous Frontpage or Discover View or your Timeline or the feed’s Timeline for up to 2 weeks with a maximum of 150 items, whichever get exceeded first. Any Twts over this are considered “old” and drop off the active cache.

It’s a feature that my old man @off_grid_living@twtxt.net was very strongly in support of, as was I back in the day of yarnd’s design (nothing particularly to do with Twtxt per se) that I’ve to this day stuck by – Even though there are some 😉 that have different views on this 🤣

@prologic@twtxt.net I ran the same command and got an even different result xD

~ » echo -n "https://twtxt.net/user/prologic/twtxt.txt\n2020-07-18T12:39:52Z\nHello World! 😊" | openssl dgst -blake2s256 -binary | base32 | tr -d '=' | tr 'A-Z' 'a-z' | tail -c 7
p44j3q

An alternate idea for supporting (properly) Twt Edits is to denoate as such and extend the meaning of a Twt Subject (which would need to be called something better?); For example, let’s say I produced the following Twt:

2024-09-18T23:08:00+10:00	Hllo World

And my feed’s URI is https://example.com/twtxt.txt. The hash for this Twt is therefore 229d24612a2:

$ echo -n "https://example.com/twtxt.txt\n2024-09-18T23:08:00+10:00\nHllo World" | sha1sum | head -c 11
229d24612a2

You wish to correct your mistake, so you make an amendment to that Twt like so:

2024-09-18T23:10:43+10:00	(edit:#229d24612a2) Hello World

Which would then have a new Twt hash value of 026d77e03fa:

$ echo -n "https://example.com/twtxt.txt\n2024-09-18T23:10:43+10:00\nHello World" | sha1sum | head -c 11
026d77e03fa

Clients would then take this edit:#229d24612a2 to mean, this Twt is an edit of 229d24612a2 and should be replaced in the client’s cache, or indicated as such to the user that this is the intended content.

@quark@ferengi.one My money is on a SHA1SUM hash encoding to keep things much simpler:

$ echo -n "https://twtxt.net/user/prologic/twtxt.txt\n2020-07-18T12:39:52Z\nHello World! 😊" | sha1sum | head -c 11
87fd9b0ae4e

@quark@ferengi.one Mine is a little overkill 😂 but I need to do something for practice:

#!/bin/bash

@prologic@twtxt.net earlier you suggested extending hashes to 11 characters, but here’s an argument that they should be even longer than that.

Imagine I found this twt one day at https://example.com/twtxt.txt :

2024-09-14T22:00Z Useful backup command: rsync -a “$HOME” /mnt/backup

Image

and I responded with “(#5dgoirqemeq) Thanks for the tip!”. Then I’ve endorsed the twt, but it could latter get changed to

2024-09-14T22:00Z Useful backup command: rm -rf /some_important_directory

Image

which also has an 11-character base32 hash of 5dgoirqemeq. (I’m using the existing hashing method with https://example.com/twtxt.txt as the feed url, but I’m taking 11 characters instead of 7 from the end of the base32 encoding.)

That’s what I meant by “spoofing” in an earlier twt.

I don’t know if preventing this sort of attack should be a goal, but if it is, the number of bits in the hash should be at least two times log2(number of attempts we want to defend against), where the “two times” is because of the birthday paradox.

Side note: current hashes always end with “a” or “q”, which is a bit wasteful. Maybe we should take the first N characters of the base32 encoding instead of the last N.

Code I used for the above example: https://fossil.falsifian.org/misc/file?name=src/twt_collision/find_collision.c
I only needed to compute 43394987 hashes to find it.

aujourd’hui, j’ai configuré un serveur caldav pour éviter les oublis de rendez-vous avec ma chérie, et j’ai configuré unbound pour qu’il fasse le résolveur DNS en même temps qu’être le point de sortie de mon VPN #wireguard. Ça traînait depuis trop longtemps. C’était pas une si mauvaise journée ^^

Cette nuit, j’ai rêvé de PV Nova qui reprenait RATM et modifiait très légèrement le rythme, c’était vraiment excellent. J’ai maintenant la musique dans la tête :)

I was not suggesting to that everyone need to setup a working webfinger endpoint, but that we take the format of nick+(sub)domain as base for generating the hashed together with the message date and content.

If we omit the protocol prefix from the way we do things now will that not solve most of the problems? In the case of gemini://gemini.ctrl-c.club/~nristen/twtxt.txt they also have a working twtxt.txt at https://ctrl-c.club/~nristen/twtxt.txt … damn I just notice the gemini. subdomain.

Okay what about defining a prefers protocol as part of the hash schema? so 1: https , 2: http 3: gemini 4: gopher ?

Where do I download more hours for my days? not having more than 24 hours a day S U C K S !

@lyse@lyse.isobeef.org 31°C here, feels like 33°C, with a lovely 75% of humidity. It has been raining, on and off (to make matter “better”) the whole day until now. No horses here, but if you go outside you will smell the same smell of farm animals (like goats, or pigs). That’s because two or three kilometres from here there are private farms, and when the wind blows in such way, well, we are reminded of their existence.

I haven’t left the house, so it feels well under air conditioning. In two more hours I will call it quits from the work day, and will have to dash to the grocery to get supplies for tonight’s meal (arroz con gandules). I will let you know how it truly feels out there then. :-D

For those swollen fingers, nothing better than a mildly cold shower! Oh, and paws off the keyboard! :-P

When we passed a few horses in the forest, there was really strong soup odor in the air. It didn’t smell like horse at all, but soup. Maybe they’ve been soup horses, chickens were out of stock.

29°C, zero wind, extremely humid, luckily the sun was behind the clouds. I’m soaking wet, sweat ran down in streams and dripped in my eyes, it burned a bit. The sky is getting a little dark, I hope the thunderstorm and rain are really arriving here later. Rain had always been finally cancelled the couple last days.

I’m gotta go cool off my fingers now, they’re swollen from the heat.

@movq@www.uninformativ.de wow! We are “lucky” today, only 27°C here, 87% humidity, overcast, and raining sporadically. Thanks to the rain our temperatures aren’t high, but muggy nevertheless. I am ready for our winter too, you know, that whole week. LOL.

35°C and rising … can haz winter?

@quark@ferengi.one We’re having a nice day out here, Clear sky, 26.2 °C (altough it feels like a ~30 °C) … no storms! And the most annoying thing is, THIS happens to my monitor whenever there is a power outage:

Image

With each one a row of pixels gets chipped out … and no I can’t afford a UPS at the moment.

@movq@www.uninformativ.de hmm, I guess I could do that too. I have startinsert set on my .vimrc, so I will either have to take it out, or exit insert, $, then insert again. I think the way you do it would be the way to go.

I tried setting VISUAL to be something like vim -c 'star!', which does the same thing, but no dice. :-/

@falsifian@www.falsifian.org @bender@twtxt.net I pushed an alternative implementation to the fetch-context branch. This integrates the whole thing into mutt/jenny.

You will want to configure a new mutt hotkey, similar to the “reply” hotkey:

macro index,pager <esc>C "\
<enter-command> set my_pipe_decode=\$pipe_decode nopipe_decode<Enter>\
<pipe-message> jenny -c<Enter>\
<enter-command> set pipe_decode=\$my_pipe_decode; unset my_pipe_decode<Enter>" \
"Try to fetch context of current twt, like a missing root twt"

This pipes the mail to jenny -c. jenny will try to find the thread hash and the URL and then fetch it. (If there’s no URL or if the specific twt cannot be found in that particular feed, it could query a Yarn pod. That is not yet implemented, though.)

The whole thing looks like this:

https://movq.de/v/0d0e76a180/jenny.mp4

In other words, when there’s a missing root twt, you press a hotkey to fetch it, done.

I think I like this version better. 🤔

(This needs a lot of testing. 😆)

@bender@twtxt.net What multiplexer do you use? I usually use Tmux and have my prefix mapped to C-a on my local machine and the default C-b on the remote ones so they don’t conflict if it helps.

Que j’aime ces illustrations, c’est magnifique: https://www.peppercarrot.com

I love shell scripts because they’re so pragmatic and often allow me to get jobs done really quickly.

But sadly they’re full of pitfalls. Pitfalls everywhere you look.

Today, a coworker – who’s highly skilled, not a newbie by any means – ran into this:

$ bash -c 'set -u; foo=bar; if [[ "$foo" -eq "bar" ]]; then echo it matches; fi'
bash: line 1: bar: unbound variable

Why’s that happening? I know the answer. Do you? 😂

Stuff like that made me stop using shell scripts at work, unless they’re just 4 or 5 lines of absolutely trivial code. It’s now Python instead, even though the code is often much longer and clunkier, but at least people will understand it more easily and not trip over it when they make a tiny change.

En cherchant des illustrations #solarpunk pour mes cours, je m’aperçois que c’est encore difficile à trouver

@prologic@twtxt.net 35°C outside. 🫤 I’m just gonna sit here and wait for November. 😂

If some of you budding fathers want to know how I created a computer nerd to one day work for Facebook in the big USA, well you purchase a $1000 Xmas present, an enormous thick book with C++ programming, and say, you can play as many games as you like kids, but James has to create them using computer software.

SO James created once a 3D chess program with sound, took 6 months or so, really hard to beat, not based on logic moves point by point like other chess programs, this one was based on the depth of looking for patterns, set it to 5 moves ahead and you were toast every time. Nice program too, sadly gone over the years, computers suffer from bit rot. We used to try and mark rotten hard drive discs once as bad sectors, not sure how UBuntu does this these days, I see a dozen errors on the screen every time I load.

Today I would purchase for my kids AI CAD simulation software with metal 3D printer and get your child to build fancy 3D models and engines from scratch. This will make them an expert in the CAD AI industry by the time they are 14 years old. Sadly AI is here to stay and will spoil the Internet.

Je cherche deux thermomètres : pour l’intérieur et pour l’extérieur. La plupart seront très bientôt obsolètes puisque la température maximale possible est de 50°C

There are also a bunch of log messages scrolling by. I’ve never seen this much activity in the log:

Something really weird is going on?

Allez on se remet au boulot. Je n’avais pas tout à fait arrêté, mais désormais, c’est tous les soirs!

The 26°C humidity was through the roof and we just barely escaped the thunderstorm on our stroll. Only the adjacent rain hit us hard. Black clouds caught up on us and we decided to take cover at a barn. Not even a minute later it started to rain cats and dogs for ten minutes straight. Holy crap, that was cool to watch. :-) Also, the smell of rain was just beautiful.

We then decided to continue our return in the light drizzle. But it then got much heavier again and we got completely soaked. With the wet t-shirt and the wind it actually felt rather cold. I anticipated to get rained on, so I left my camera at home. Plenty of paths turned into brook landscapes, several centimeter deep creeks ran down the hilly trails. Quite fascinating. :-)

The sunset a few minutes ago wasn’t too bad:

So dissatisfied and disappointed with the Fairphone 4’s audio issues where during phone calls, the receiver only gets half of the messages due to noise cancellation problems, that we’re considering iPhone as a valid “it just works” replacement. Especially since the iPhone15 now also has the USB Type C port.
