Welcome to Mastodon! Want to find your Twitter friends here? Try this:
wait wait, so I don't see all replies? why is the hashtag search so broken? what do you mean, "don't make your account at mastodon.social", where do I join then? this user is here since 2018 but I don't see any toots in their profile page? where's the quote-retweet? how do I find people to follow??
A futuristic Mastodon introduction for 2021: Focusing on things that come up frequently and I don’t see explained that often.
Three questions I’ll be thinking about: 1) What is fedi? 2) Why is it called the fediverse? 3) Why are there servers did I pick the right one or should I be somewhere else am I posting to it right now?
@cthychl Also servers all talk to each other! There are some "details" around that, but generally, you can talk to anyone on any instance from anywhere
@cthychl AFAIK fedi is just a contraction of fediverse. Some people call it the 'verse (OK, maybe just me ;). The term fediverse was coined as a catch-all term for the network made up of all the instances of all the different fedi software (GNU Social, Mastodon, Pleroma, etc). An instance is a copy of any piece of fedi-compatible software running on a server somewhere, see:
Fast character case conversion (or how to really compress sparse arrays):
Converting strings and characters between lower and upper cases is a very common need.https://github.com/apankrat/notes/tree/master/fast-case-conversion
In particular, case conversion is often used to implement case-insensitive comparision, an operation that is often present on the program's fast paths as a part of data container lookups and content manipulation.
So it is usually desirable to make case conversions as fast as possible.
In this post we are going to look at one of the options - very fast case conversion using compressed lookup tables and also at some options for compressing these even further.
Stop writing Twitter threads! (Pierre Equoy):
So please, please, if you plan on writing something longer than a bad joke or a snarky comment, do not use Twitter. Your ideas, your findings, your knowledge deserve better. Put your thoughts on your own website or blog, and share it with the World using whatever social network you see fit.These apply much more so to the Fediverse, where you don't have the stupid character limitation.
Wow. This guy doesn't understand the first thing about what makes Ozark a great show:
"This is a show that has built its entire foundation on dislikeable characters – truly, truly despicable human beings. The Byrde family, from top to bottom, has little to no redeeming values."
One problem with the cinema business is that customers are supposed to pay for the product *before* they get to find out if it's any good. This skews the market towards safe and familiar productions, rather than brave and innovative ones. It forces film-makers to shoehorn experimental ideas into established "franchises", instead of being allowed to tell new stories, with new characters in new worlds, where their ideas can be judged on their own merits by an audience with no major expectations.
Insightful thought, but... doesn't this apply to mostly all artistic disciplines, e.g. books? You always pay before being able to know if you like it or not.
I was about to say it happens on music records at well, but the economic model has changed on this as you don't buy those things anymore.
¿Es más sostenible lavar a mano o usar el lavavajillas? · Maldita.es - Periodismo para que no te la cuelen
Estropeo el clickbait: usar el lavavajillas consume menos agua y menos energía para calentarla que lavar a mano.
Además, hay otra cosa que (creo que) el artículo no menciona: usar el lavavajillas es más higiénico porque las temperaturas que se alcanzan dentro también achicharran a buena parte de los bichos.
Time is an illusion, Unix time doubly so... (Jan Schaumann):
"At the time we didn't have tapes and we had a couple of file-systems running and we kept changing the origin of time," he said. "So finally we said, 'Let's pick one thing that's not going to overflow for a while.' 1970 seemed to be as good as any. "https://www.netmeister.org/blog/epoch.html

Tengo un netbook viejo que quiero poner en marcha para mi hija, que se ha empeñado en tener uno ligero para tomar notas.
¿Alguien tiene experiencia con una distribución Linux que funcione medianamente bien con estas máquinas?
@VictorMoral Todo depende de qué tan viejo 😉
Por aquí tenemos un *realmente* viejo asus de 8 años que corre openSUSE Leap 15.4 con escritorio Plasma sin problemas. Nada de aplicaciones gráficas pesadas e incluso desinstalé TeXLive para tener más espacio de disco, pero para navegar por internet o usar LibreOffice funciona perfecto.
En definitiva, usa la distribución Linux que mejor conozcas, realmente no hay tanta diferencia.
@RGBes es arquitectura 32bits. Ya no hay tanto soporte para ella. Yo siempre empleo Debían pero incluso con xfce requiere recursos. Y libreoffice todavía pero la.navegación es mucho más complicada si apenas tienes RAM
@VictorMoral Entonces está difícil. Como bien dices, ya casi no quedan distros de 32 bits. Ni idea.
@VictorMoral Si se trata de una notebook de mas de 10 años, Antix basada en debian. Menos de 10 años debian con escritorio LXDE
@VictorMoral Te irá bien casi cualquier distro, si le pones un disco duro SSD.
Igual es el momento de que pruebes OpenBSD. El soporte de 32bits es completo y no tengo noticia de que piensen abandonarlo en breve. No necesita demasiados recursos y tienes todos los escritorios ligeros que conoces.
OPEN LETTER: Make DMs Safe
Facebook recientemente entregó mensajes directos entre una madre y su hija adolescente a la policía. Ahora están siendo procesadas bajo la ley antiaborto del estado. En un mundo cada vez más peligroso, hay una cosa simple que toda plataforma de mensajería debe hacer en este momento: hacer que nuestros mensajes sean seguros mediante el cifrado de extremo a extremo.
What is Btrfs in Linux? What are its Advantages Over Ext4?
From the article:
Unlike Ext4, Btrfs does not support encryption [...]Does ext4 really support encryption? I meant, of course you can use LUKS and ext4 over it, but...
Perceptual hashing (Matt Rickard):
Hashing algorithms map data to an arbitrary fixed-size value. Most hashing algorithms actively try to avoid collisions – e.g., minimizing the probability of two different keys having the same hash. Perceptual hashes do the opposite – they maximize collisions by creating some dimension of data locality – similar keys have similar hashes.https://matt-rickard.com/perceptual-hashing
No me acordaba que los lineage y demás tienen botón de grabación de llamadas en cuanto éstas se producen. Dentro y fuera. Menudo alivio.
Lo de Firefox me ha costado lo mío porque no tengo servicios de Google pero al final he encontrado el enlace donde descargar las versiones de los APK.
Sincronizarlo con el resto de mis dispositivos está chupado así que ahora voy con el resto y luego, al final, le pondré el SIM y a gozar.
OpenBSD 7.2 has been released:
Congratulations to everyone involved.
My OpenBSD home server and my OpenBSD laptop have been upgraded with no problem. Maybe even faster than in previous releases.
ps program now implements the
-f (forest) argument, which is not really that important, but makes my muscle memory happy because I'm accustomed to decades of Linux typing
pkg_add -u command is now blazing fast.
This is a fantastic piece of work by a fantastic group of people. If you use it, it would be nice to contribute:
How to check if any word is zero (Wojciech Muła):
20 years ago, if you ate dinner under the unblinking eye of a CCTV, it was because you were housed in a supermax prison. Today, it's because you were unwise enough to pay hundreds or thousands of dollars for "home automation" from Google, Apple, Amazon or another "luxury surveillance" vendor.https://pluralistic.net/2022/10/07/sensory-deprivation/#sensorship
@chuso joder. Qué lástima. ¿Y no hay otro cliente de telegram? Les perdí la pista hace tiempo.
@firstname.lastname@example.org @VictorMoral@mastodon.social yo uso el servicio web y lo tengo siempre abierto en una pestaña del Firefox (de esas pinned, pequeñitas, a la izquierda). Igual me pierdo alguna funcionalidad, pero yo no he echado de menos nada.
While re-reading ActivityPub documentation, I've discovered that there is a
Dislike message type. Not to repent from liking something (that would be an
Like message), but to actively show your disapproval of something 🤷
Something that needs to happen in Sci-Fi: Crew powers on the alien computer to be greeted with an obvious countdown timer under alien text.
Panic because countdown.
After the countdown has elapsed... no explosion. They look at the computer and it's finishing up playing a short animation before going to a login prompt.
And that's how they learn about alien bootloaders and OS selection timeouts.
No sé si será el caso, pero he visto que los programas hechos en Go ocupan locuras como esas.
Let's talk HTTP status codes and Service Workers. A 🧵.
4xx HTTP codes are "client error" codes: the server is telling the client (often the browser) that the client did something wrong: requested a resource that doesn't exist, or which is forbidden, for example.
5xx HTTP codes are "server error" codes: the server is informing the client that the server did a boo boo: some internal error, gateway timeout, etc.
Okay, which code should a Service Worker use when it itself fails?
A fetch() in a Service Worker can fail for reasons related to the server — actual 4xx or 5xx errors issued by the server it is fetching data from. In such a case, easy, pass on the code received from the server.
…what if the Service Worker *itself* failed for some reason that is *not* related to the server it is fetching content from?
Say, there's a bug somewhere in the code of the Service Worker itself. And let's assume that this particular buggy code happens to be wrapped in a nice try-catch block.
The Service Worker can and should issue some kind of an error code to the user — otherwise the browser will display a generic "Site cannot be reached" message. Not very useful, that!
My opinion is that it should return a 5xx as a way to tell the client they did not do anything wrong. If the client is a user-operated web browser there is not much to do about it, but if the client is a library it tells the programmer that the error is not their fault (i.e. packets are not malformed nor data missing and so).
Good question, anyhow.
Still 4 days to wait
If you look at some mirrors, sometimes you could get it a days or two before the release

The multiocular O is a rare form of the Cyrillic letter О. How rare?https://languagehat.com/multiocular-o/
Rare enough to occur in a single phrase, in a single text written in an extinct language, Old Church Slavonic.
The text is a copy of the Book of Psalms, written around 1429 and kept in Russia
It's not new at all (2005, things may have changed very much), but this document about the architecture of QEMU from its author Fabrice Bellard is fascinating:
Read out there:
What's the word that's not schadenfreude, but means "enjoying someone else's tech misery because, thank fuck it's not me, but also hoping the poor schmuck manages to solve his problem because, (a) he's a nice guy and (2) I really want to know the solution".😆
Using a Framework will harm the maintenance of your software:
Poor man's profiler, or profiling a running program with a cheap combination of gdb, awk and scripting:
Sampling tools like oprofile or dtrace's profile provider don't really provide methods to see what [multithreaded] programs are blocking on - only where they spend CPU time. Though there exist advanced techniques (such as systemtap and dtrace call level probes), it is overkill to build upon that [...]http://poormansprofiler.org/
[...] one needs to improvise, like.. use debuggers - they can walk threads and provide stacks.
Tinyphysicsengine: Minimalist 3D C99 single-header physics engine
Linux NILFS file system: automatic continuous snapshots
@dekkzz78 For my case it was physics research data, but @solene is 100% correct here: snapshots help when you or a program deletes a file that you wanted after all, but if the whole filesystem is unreliable then snapshots won't help you.

Though I understand those who were against it, I think this is a very good decision.
Debian will be much more accessible and easier to install, and that can only be good for everyone.
