In-reply-to » on my yarn pod nothing really embeds (not even images) so i'm looking at the embed rules part of the mod settings and i'm like... i don't know how to do any of this 😭😭😭

There is a missing feature I’ve been intending to add to though, which is that any link that looks like a URL that might be an image, for example, ends with .png or .jpg or whatever, we should just render that as an image and not expect users to wrap it in Markdown image links ![](...)

37C3 and New Year’s Eve 2023
Another one from the vaults. The 37C3 conference took place in
December, 2023. This report was mostly written in January, 2024.
Mostly finished it at night in my cottage between 28 and 29th
December, then edited and added some stuff in July, 2025. So… Only
1.5 years late?

It was a little ironic, and a little sad, that I was finishing the
37C3 report during 38C3. I didn’t manage to get any tickets for me and
#3 for 38C3 and had to make do with watching the stream.

In-reply-to » PSA: setpriv on Linux supports Landlock.

@prologic@twtxt.net Yeah, it’s not a strong sandbox in jenny’s case, it could still read my SSH private key (in case of an exploit of some sort). But I still like it.

I think my main takeaway is this: Knowing that technologies like Landlock/pledge/unveil exist and knowing that they are very easy to use, will probably nudge me into writing software differently in the future.

jenny was never meant to be sandboxed, so it can’t make great use of it. Future software might be different.

(And this is finally a strong argument for static linking.)

In-reply-to » PSA: setpriv on Linux supports Landlock.

Another example:

$ setpriv \
    --landlock-access fs \
    --landlock-rule path-beneath:execute,read-file:/bin/ls-static \
    --landlock-rule path-beneath:read-dir:/tmp \
    /bin/ls-static /tmp/tmp/xorg.atom

The first argument --landlock-access fs says that nothing is allowed.

--landlock-rule path-beneath:execute,read-file:/bin/ls-static says that reading and executing that file is allowed. It’s a statically linked ls program (not GNU ls).

--landlock-rule path-beneath:read-dir:/tmp says that reading the /tmp directory and everything below it is allowed.

The output of the ls-static program is this line:

─rw─r──r────x 3000 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

It was able to read the directory, see the file, do stat() on it and everything, the little x indicates that getting xattrs also worked.

3000 and 200 are user name and group name – they are shown as numeric, because the program does not have access to /etc/passwd and /etc/group.

Adding --landlock-rule path-beneath:read-file:/etc/passwd, for example, allows resolving users and yields this:

─rw─r──r────x cathy 200 07-12 09:19 22'491 │ /tmp/tmp/xorg.atom

Pessoas da comunidade brasileira de #ProgramaçãoCriativa por muitos anos fizeram encontros sob o nome promovido pela Fundação Processing, os chamados #ProcessingCommunityDay, fizemos encontros em várias cidades e então depois de 2020, com a pandemia do COVID-19, fizemos três eventos nacionais muito inspiradores em 2021, 2022 e 2023 (vide https://compoetica.github.io/links/)

Ano passado não conseguimos fazer e este ano pretendemos retomar, só que usando outro nome: #Compoética. Vamos aos poucos divulgar mais sobre o encontro brasileiro de programação criativa em https://compoetica.github.io/CP2025/

Meus agradecimentos profundos ao @guilhermesv@guilhermesv que dedica generosamente um enorme esforço para organizar esses eventos da comunidade e cria o design e peças de comunicação sempre emocionantes de lindos.

In-reply-to » This aggressive auto-logout on my bank’s website …

@movq@www.uninformativ.de Yeah, it’s a shitshow. MS overconfirms all my prejudices constantly.

Ignoring e-mail after lunch works great, though. :-)

Our timetracking is offline for over a week because of reasons. The responsible bunglers are falling by the skin of their teeth:

Image

  1. The error message neither includes the timeframe nor a link to an announcement article.
  2. The HTML page needs to download JS in order to display the fucking error message.
  3. Proper HTTP status codes are clearly only for big losers.
  4. Despite being down, heaps of resources are still fetched.

I find it really fascinating how one can screw up on so many levels. This is developed inhouse, I’m just so glad that we’re not a software engineering company. Oh wait. How embarrassing.

In-reply-to » @bender Both Gopher and Mastodon are a way for me to “babble”. 😅 I basically shut down Gopher in favor of Mastodon/Fedi last year. But the Fediverse doesn’t really work for me. It’s too focused on people (I prefer topics) and I dislike the addictive nature of likes and boosts (I’m not disciplined enough to ignore them). Self-hosting some Fedi thing is also out of the question (the minimalistic daemons don’t really support following hashtags, which is a must-have for me).

@bender@twtxt.net Yeah, well, it’s a bit like twtxt. There is a Gopher community, but it’s small. I actually don’t like that HTTP is so easily accessible. I don’t like it that much when people post links to my site on HackerNews or something like that. Too much exposure.

Gopher is a small world. It’s slow and cozy.

And much like twtxt, the protocol is simple®, so it’s easier to tinker with it.

In-reply-to » @lyse those are pretty cool! The one change I would recommend doing pronto is the colour of the hyperlinks. Ay, ay, ay, my retina! :-P

@quark@ferengi.one Ta. Hmm, what’s wrong with the blue text color? Is it too dark on the black background for you? :-?

Normal links are blue while images are teal. I thought I differentiate the two if I easily can. The underline of URLs comes from my terminal and is not tt’s fault.

Configuring colors is in the todo list. But of course, providing a sane default is definitely something I’d like to have.

Passing of Jean-Raymond Abrial
Jean-Raymond Abrial, father (in particular!) of the Z notation, but also of the B method, and then Event-B, passed away on May 26. I was surprised to see that this piece of news, which may be of some interest to formal method folks, doesn’t seem to be very well known (there’s not much material on the web).

Here are some links (on LinkedIn, sorry):

Also spent the morning continuing to think about a new design for EdgeGuard’s WAF. I’m basically going to build an entirely new pluggable WAF that will be designed to only consider Rate Limiting, IP/ASN-based filtering, JavaScript challenge handling, Basic behavioral analysis and Anomaly detection.

The only part of this design I’m not 100% sure about is the Javascript-based challenge handling? 🤔 I’m also considering making this into a “proof of work” requirement too, but I also don’t want to falsely block folks that a) turn Javascript™ off or b) Use a browser like links, elinks or lynx for example.

Hmmm 🧐

In-reply-to » I've just released version 1.0 of twtxt.el (the Emacs client), the stable and final version with the current extensions. I'll let the community maintain it, if there are interested in using it. I will also be open to fix small bugs. I don't know if this twt is a goodbye or a see you later. Maybe I will never come back, or maybe I will post a new twt this afternoon. But it's always important to be grateful. Thanks to @prologic @movq @eapl.me @bender @aelaraji @arne @david @lyse @doesnm @xuu @sorenpeter for everything you have taught me. I've learned a lot about #twtxt, HTTP and working in community. It has been a fantastic adventure! What will become of me? I have created a twtxt fork called Texudus (https://texudus.readthedocs.io/). I want to continue learning on my own without the legacy limitations or technologies that implement twtxt. It's not a replacement for any technology, it's just my own little lab. I have also made a fork of my own client and will be focusing on it for a while. I don't expect anyone to use it, but feedback is always welcome. Best regards to everyone. #twtxt #emacs #twtxt-el #texudus

@ About the URL, since it no longer used for hashing there might be no need to change it. I agree that we keep all the parts that already are out there for the most parts. Instead of a contact field you could also just use links like: link = Email mailto:user@example.dk or link = Signal https://signal.me/sthF4raI5Lg_ybpJwB1sOptDla4oU7p[...]

@andros@twtxt.andros.dev Thanks for consolidating a lot of good ideas. Especially how you have deiced to just extend the mention syntax for location-based treads. This might even be backward compatible with older (pre-yarn) clients.
What about using Z for UTC +00:00- is that allowed in your specs?
Regarding url = I would suggest to only allow one and the maybe add url_old = or url_alt = !?
I’m still not a fan of a DM feature, even thou it helps that i have now been split out into a separate feed file. Instead if would suggest a contact = field for where people can put an email or other id/link for an established chat protocol like signal or matrix.

@bender@twtxt.net Yes, you right. But is premium for more than that.
I use a feature I love a lot: customising different searches with different themes or links.
It’s easy to understand with an example. I have a search with the name “Django”. I set sources: Django documentation, stack overflow, topic “programming” and so on. It’s very quick to find Django solutions.
I also have another way to find my stuff: search my blog and repositories.
I had problems paying for the first mouths, now it’s a working tool for me.
