Not at all! I love @FediTips, I boost their posts and send links to their work often. Our Help Centre is specifically geared towards Mastodon.social users, and the guide is intended as a quick primer to help people get up to speed on our cultural norms.

When it comes to getting the word out about the , and educating people about how to have a good time here, I generally take the attitude more better!

Yeah, to make clear, Hannah has been great at responding to queries and listening patiently to criticism! I think that comes through in this thread for example?

And yes it's good to have more than one source of tech support. I encourage people to do their own support sites and/or use my text as a basis if they want to as it's available under CC-By-SA. I don't want to end up as a single point of failure on a site encouraging decentralisation 🙂

Having amazing colleagues means someone brings up a random animal fact. Then another one continues with a 2nd. And at the end of the coffee break you have 3 fun random animal facts, and a French royalty fact (for the person who didn't have animal ones) that make you smile for the end of the day 😁

Question for Emacs wizards. I found a strange thing which I could not understand after reading the documentation (gnu.org/software/emacs/manual/) and even after reading the startup files, shipped with my Emacs 30.2.

If I use the -q option — Emacs will add site-lisp directories to the load-path. But with -Q option — there are no site-lisp catalogs in the load-path. Why is this happens? :drgn_confused:

Note: the option --no-site-lisp is not used in the both examples. So, as I understood after reading the gnu.org/software/emacs/manual/, even with --no-site-file (or -Q) the site-lisp catalogs should be added to the load-path in the both cases :drgn_confused:

Xterm window divided in two panes. On the one pane there is emacs -Q --batch --eval "(print load-path)" command which prints list of catalogs from /usr/local/share/emacs/30.2/lisp/*. On the second pane there is emacs -q --batch --eval "(print load-path)" command wich prints list of catalogs from /usr/local/share/emacs/30.2/lisp/* AND from /usr/local/share/emacs/30.2/site-lisp AND from /usr/local/share/emacs/site-lisp.

I was writing a blog post tangentially referencing the book "Weapons of Math Destruction" (which itself points to the unfair and sometimes deadly consequences of algorithms) when a friend shared the link below.

Leaked data from Persona (identity verification) only corroborates the awful extension from the premise of Weapons of Math Destruction and the recycling of bad practices from a decade ago...

From the post:

"The blog [from the security researcher] claims that 2,456 source files expose 269 verification checks offered to government customers, including checks for whether a face looks “suspicious,” and two parallel systems for politically exposed persons (PEPs)."

I wonder what is being used to check whether a face looks suspicious? It's not an AI system that is based on data that inherently discriminates against marginalized people, right? ... Right?

Databases aren’t going away, but how they fit in the modern data landscape is changing.

"This is a milestone year for America. It marks both the 250th anniversary of the signing of the Declaration of Independence and the 100th anniversary of an effort to recover and recount the contributions of Black Americans left out of the national narrative—what was launched in 1926 as Negro History Week and then became Black History Month in 1976.

One anniversary honors the nation’s founding ideals; the other reckons with its failures to live up to them."

You voted for this slogan and now it's here! We have a new batch of super nice t-shirts (they're 100% organic cotton with a thick, soft feel) with a cute screen printed design from @dopatwo. "My friends are not for sale"—because your connections to other people are more than a bargaining chip for big tech companies to keep you from leaving them.

Telekom Austria startet bald KI-Agenten für Kundenservice

Die Telekom Austria startet im ersten Quartal 2026 ihr KI-Angebot für "alles rund um Kundenservice", wie es Firmenchef Alejandro Plater formulierte. Es werde auf einer Plattform ein "Ökosystem von KI-Agenten" als Dienst für anderer Firmen aus unterschiedlichen Sektoren angeboten. "Sie werden bald mit einem KI-Agenten sprechen und es gar nicht bemerken." Dieser werde alle Sprachen, auch regionale Dialekte erkennen und im gleichen Idiom antworten, schwärmte Plater.

@hongminhee洪 民憙 (Hong Minhee) :nonbinary: from the point of view of someone who is "maintaining" a JSON-LD processing fedi software and has implemented their own JSON-LD processing library (which is, to my knowledge, the fastest in it's programming language), JSON-LD is pure overhead. there is nothing it allows for that can't be done with

1. making fields which take multiple values explicit
2. always using namespaces and letting HTTP compression take care of minimizing the transfer

without JSON-LD, fedi software could use zero-ish-copy deserialization for a majority of their objects (when strings aren't escaped) through tools like serde_json and Cow<str>, or System.Text.Json.JsonDocument. JSON-LD processing effectively mandates a JSON node DOM (in the algorithms standardized, you may be able to get rid of it with Clever Programming)

additionally, due to JSON-LD 1.1 features like @type:@json, you can not even fetch contexts ahead of time of running JSON DOM transformations, meaning all JSON-LD code has to be async (in the languages which has the concept), potentially losing out on significant optimizations that can't be done in coroutines due to various reasons (e.g. C# async methods can't have ref structs, Rust async functions usually require thread safety due to tokio's prevalence, even if they're ran in a single-threaded runtime)

this is after context processing introducing network dependency to the deserialization of data, wasting time and data on non-server cases (e.g. activitypub C2S). sure you can cache individual contexts, but then the context can change underneath you, desynchronizing your cached context and, in the worst case, opening you up to security vulnerabilities

json-ld is not my favorite part of this protocol

@kopperkopper :colon_three: @hongminhee洪 民憙 (Hong Minhee) :nonbinary: As the person probably most responsible for making sure json-ld stayed in the spec (two reasons: because it was the only extensibility answer we had, and because we were trying hard to retain interoperability with the linked data people, which ultimately did not matter), I agree with you. I do ultimately regret not having a simpler solution than json-ld, especially because it greatly hurt our ability to sign messages, which has considerable effect on the ecosystem.

Mea culpa :\

I do think it's fixable. I'd be interested in joining a conversation about how to fix it.

Do you want to design a cross-stitch pattern? This website is neat.

Now to try to figure out how to print this. If it works it could be fun to make different species.

I think I'd like to see how small I can make the patterns. Since I am very lazy and won't complete a big complex project.

There are also sites that will convert photos, but the results look like waaaay too much work to really make.
