This framing is so gross. To see (human!) generated (ahem: English) text to be a "vital resource" you have to be deeply committed to the project of building AI models and in this particular way.

@emilymbender There is a demand for low-background steel, steel produced before the nuclear tests mid century, for use in Geiger counters. They produce it from scavenging ships sunk during world war one, as it's the only way they can be sure there is no radiation.
The same is going to happen for internet data, only archives pre-2022 will be usable for sociology research and the like as the rest will be contaminated by AI nonsense. Absolute travesty.
TIL that there is something named linker optimization that forces the deletion of unused functions in your final executable. As a bonus, you get the list of unused functions as compiler warnings (dead code is always bad, so you get the change to delete them or comment them out).
If you have a standard build system, do the following:
make CFLAGS="-ffunction-sections -fdata-sections" LDFLAGS="-Wl,--gc-sections -Wl,--print-gc-sections"
In praise of Plan 9 (Drew DeVault):
While I totally agree on the message, if cars are used at their full capacity (5 people), you only need 1000 / 5 = 200 cars to move a thousand people, not 625.
@firstname.lastname@example.org Do you ever see cars used to their full capacity, especially when there is lots of traffic?
Sam Bankman-Fried, el pájaro este que estafó miles de millones de dólares con su criptochiringuito FTX y que se fugó del país, ha sido puesto en libertad bajo fianza.
Esto nos recuerda dos cosas: que los EEUU son un país de chichinabo y que el sistema de fianzas es otro castigo para pobres.
Me gustaría saber si aquí también hay gente mayor de 45-50 y cómo encontrarlos, no sé si alguien me puede ayudar. Gracias de antemano 😌

Frases que me revientan: “los laístas habláis mal”.
No. La RAE puede decir misa. Pero los laístas hablamos... con laísmo. Igual que hay quien tiene un acento determinado. No es incorrecto.
(Y no. Tampoco es incorrecto tener acento.)
@manu Pensaba que el laísmo era algo solo de Valladolid
Es laísmo es andaluz, se extendió a Castilla-La Mancha hasta Madrid.
Es gramaticalmente incorrecto.
No es como el leísmo que se considera un cultismo para Objeto Directo de persona masculina.
Los acentos al hablar son todos correctos.
El español castellano más "puro" es el de Valladolid y Burgos. Es como la Received Pronunciation del inglés británico o el Parisino del francés hexagonal.
Los catalanes y gallegos no son laístas. Y los vascos solo algo leístas.
Linux's strcmp() For The m68k Has Always Been Broken:
The m68 hand-written assembler version of strcmp() has always been broken: it returns the difference between the first non-matching byte done as a 8-bit subtraction.https://www.phoronix.com/news/Linux-m68k-strcmp-Always-Broken
That is _almost_ right, but is broken for the overflow case. The strcmp() function should indeed return the sign of the difference between the first byte that differs, but the subtraction needs to be done in a wider type than 'char'. Otherwise the ordering isn't actually stable.

Just noticed that @grunfink's #SNAC (https://codeberg.org/grunfink/snac2, Social Networks Are Crap, a simple, #minimalistic #ActivityPub instance written in #C → #Fediverse) is now available in #Debian Experimental: https://tracker.debian.org/pkg/snac2
Never heard of it before, but having a Mastodon-compatible instance packaged in Debian is great. So maybe time for my own instance? 😁 Will at least toy around with it. The question is on which host. But I suspect my Raspberry Pi running Debian Unstable will do. 😎
@grunfink: Ok, #SNAC is now running on my #RaspberryPi 2 running #Debian Unstable #armhf at @email@example.com. (BTW, who can guess the wordplay in the hostname? 😎) The host has #IPv6 and is reachable from the Internet by #IPv6only, though. For now I'm just toying around with it, checking how the #Fediverse can look like, too, so don't expect too much from following it for now.
It's reverse-proxied by an #ApacheHTTPd as I'm an old-school guy and I know how to run Apache HTTPds since around 1999. 🧔
@grunfink: And since ever I wrote that posting, the snac httpd (version 2.11 in Debian Experimental) on my Pi continues to crash with a segfault after a few seconds. *sigh* Will try to get a coredump and write a bug report in Debian and hoping for the package being updated to 2.15 soonish as 2.12 and and 2.14 both fix some crashes according to the release notes.
I'm sorry to read this.
Certainly there were some crash fixes since 2.11, but they were somewhat corner cases, not something that caused crashes every few seconds.
Is this still happening? Your public timeline looks fine right now.
@grunfink: The #Debian package of #snac has been updated to version 2.15. So far @firstname.lastname@example.org ran 3 hours without issue. But then again, the previous version hadn't crashed for a while either. Let's see if it survives this mentioning. 😉
TIL that most video processing tools accept as a valid input stream a set of concatenated PPM  files, so you can generate video from your own programs easily. You just have to pipe your program's output to the appropriate tools (indicating the FPS) like
./fancy-prg | mpv --no-correct-pts --fps=$FPS -or
./fancy-prg | ffmpeg -i - -r $FPS video.mp4 https://en.wikipedia.org/wiki/Netpbm_format

What is the most trivial life lesson you would like to impart to your younger self?
Oh, that's so good.
Actual artists on Artstation, fed up with AI generators scraping their work, started posting "no AI" logos (the classic circle with a line through it) in protest.
And since "trending on Artstation" has become a common prompt among AI users, their results are all getting contaminated, as the algorithm just assumes the logos are part of the image. They're all upset about the "attack" now.
Run Your Own LastPass on Hardened OpenBSD
I've just released version 2.15 of
snac, the simple, minimalistic ActivityPub instance server. This time is mostly bugfixes:
Fixed bug in message posting that may result in 400 Bad Request errors (contributed by tobyjaffey).
Fixed crash and a deletion error in the unfollow code.
Added configuration files and examples for running snac with docker (contributed by tobyjaffey).
Serve /robots.txt (contributed by kensanata).
Use the Fediverse sparingly and wisely.
"Earlier this year, many people with Argus optical implants – which allow blind people to see – lost their vision when the manufacturer, Second Sight, went bust.
"Nano Precision Medical, the company's new owners, aren't interested in maintaining the implants, so that's the end of the road for everyone with one of Argus's 'bionic' eyes. The $150,000 per eye that those people paid is gone, and they have failing hardware permanently wired into their nervous systems.
"Having a bricked eye implant doesn't just rob you of your sight – many Argus users experience crippling vertigo and other side effects of nonfunctional implants. The company has promised to 'do our best to provide virtual support' to people whose Argus implants fail – but no more parts and no more patches."
I'm proud to announce version 2.14 of
snac, the simple, minimalistic ActivityPub instance server, that include the following new features and fixes:
Previous posts in the public and private timelines can be reached by a "More..." post at the end (contributed by kensanata).
Clicking the 'Like' and 'Boost' buttons don't move the full conversation up; after that, the page is reloaded to a more precise position. Still not perfect, but on the way.
New command-line operation,
resetpwd, to reset a user's password to a new, random one.
Added a user setup option to toggle if sensitive content is shown or not by default (contributed by kensanata).
All images are loaded in lazy mode for a snappier feel (contributed by kensanata).
Fixed crash in the data storage upgrade process when debug level >= 2 (contributed by kensanata).
Log message improvements for excelence (contributed by kensanata).
The logging of "new 'Delete'..." messages has been moved to debug level 1, because I'm fed up of seeing my logs swamped with needless cruft.
Don't show the 'Boost' button for private messages.
Added (partial) support for /.well-known/nodeinfo site information. This is not mandatory at all, but if you want to serve it, remember that you need to proxy this address from your web server to the

Drowning in AI Generated Garbage : the silent war we are fighting:
The algorithms are already feeding themselves on their own data. And, as any graduate student will tell you, training on your own results is usually a bad idea. You end sooner or later with pure overfitted inbred garbage. Eating your own shit is never healthy in the long run.https://ploum.net/2022-12-05-drowning-in-ai-generated-garbage.html
@email@example.com here it's another one (this one also talks about roles and principals):
It's the old EEE (Embrace, Extend & Extinguish) tactics used by Microsoft and other perverse corporations since forever, but I don't see a real problem. To follow:
6. Concerned Tumblr users get upset and abandon it towards free, ActivityPub-enabled software platforms
7. Other users don't care shit and keep using Tumblr
8. Tumblr screws it with usual bigtech behaviour like of them do and annoy users that move to step 6
This is totally crazy:

I'm experimenting this same thing with Firefox since upgrading to OpenBSD 7.2. Crashing also seem to match the timestamp of
pledge "rpath" log messages. I had no time to investigate seriously so I'm not sure what is causing it (sure it's not Mastodon because I don't use it). I also didn't change anything in its global configuration. Also, the
rofi tool is crashing 50% of the times I try to run it.
I'll try this weekend to find what it's happening.
Structural Regular Expressions were first described by unique genius Rob Pike when he found the line-oriented nature of usual regular expressions limiting.
An interesting article on them by Getty Ritter:
The original Rob Pike paper (PDF):
.io domains considered harmful:
@firstname.lastname@example.org As far as I know, there is no official term for what you want. In my current development team we call these ones 'interim' versions, but this is more like private slang among us. In a previous team I was a part of they called these versions (that can be very broken if you are not careful) 'unstable' checkouts.
Using the [XTerm] bell as modern notification (Antoine Baupré):
As you requested, I say hi. I've been following you from the Planet Debian RSS from like forever, and I've always enjoyed your aggregated posts, specially those regarding your kids and their love of trains. I miss those posts, they were very charming and well written.
On a more prosaic matter, I also was for years a happy user of you offlineimap application.
I totally agree with you, it's their descensus ad inferos what make the show fascinating, as they start being good people and end up being cold monsters because of the circunstancies. The case for Ruth is specially heartbreaking because he is how she is due to poverty and family issues, she tries but never succeeds.
Como estoy totalmente fuera de las redes se me pasó enterarme de que mi relato Un árbol con vistas fue finalista del premio Domingo Santos de Relato 2022.

TIL that you can have a full-path
soname in a dynamic library, so that binaries linked to it can find it even if it's in a non-standard place:
gcc -shared -o libcrazy.so -Wl,-soname,/an/esoteric/place/to/store/libcrazy.so crazy.cThis way, you don't need kludges regarding the use of
gcc -o main -L. -lcrazy main.c
LD_LIBRARY_PATHnor anything else.
I suggest that, instead of keeping the "thread" format as a chain of brief messages (which were used in Twitter to avoid one of its severe limitations), you move all your valuable information to a more suitable format, like a web page or a blog entry or somewhat similar.
Then you can publish here links to your creations for us to enjoy.
If you want to create an executable program in memory and execute it without going through the filesystem, this is how you do it (Linux only):
int fd = memfd_create("foo", MFD_CLOEXEC);https://unix.stackexchange.com/questions/230472/can-i-exec-an-entirely-new-process-without-an-executable-file
// write your image to fd however you want
fexecve(fd, argv, envp);
If you develop in C, you'll probably end up using memory leak detection tools like
libleak or the
scan-build tool from the LLVM compiler. There is a less known tool inside the GCC compiler itself: the
If you use a standard make setup, you can recompile your project doing
make CFLAGS="-fsanitize=address -fno-omit-frame-pointer"After exiting your program, a summary of memory leak errors (including the line of the source code were it happened) will be printed out.
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.
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.
Estropeo el clickbait: usar el lavavajillas consume menos agua y menos energía para calentarla que lavar a mano.

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

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
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
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.

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.
