Researching mines in northern Spain I came across this curious object. It's a canary cage designed to keep the canary alive in the event of a gas leak. If a miner saw the canary laying at the bottom of the cage it was time to abandon everything and leave the mine, but not without first closing the latched glass door and opening the valve of the oxygen bottle to save the bird. A miner would do that on their way out and take the bird with them. It's a signifier of the miner's legendary sense of solidarity, no lives lost to the mine on a miners watch. A solidarity that was also crucial in the fight for workers rights, creating safer and more humane working conditions, achievements of unionization and solidarity that some of us still enjoy today.

@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.

If you have a standard build system, do the following:

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.

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.

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.

@grunfink: The #Debian package of #snac has been updated to version 2.15. So far @xtaran@c3pio.deuxchevaux.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. 😉

OK, now I understand why I'm seeing all the #JohnMastodon jokes. 😂

A writer misread the Mastodon account that was banned from Twitter as "John Mastodon" instead of "Join Mastodon."

Alt...

To what extent is that true? Before this latest wave of suspensions, Twitter had already suspended the account posting the location of Musk’s jet. Then, the platform removed John Mastodon, the founder of a competing social media company named after himself, for posting a link to the jet tracker’s Mastodon account.

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.

Alt...

The letters AI in a red circle with a line through it, with "NO TO AI GENERATED IMAGES" underneath.

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.

From @pluralistic:

"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."

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. 😎

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 snac server.

Some internal structure improvements.

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.

Thanks. Will the fix be propagated to 7.2? I don't use -current.

Interesting things: the overall simplicity and the chunk QOI_OP_LUMA, which implements diff compression from previous byte giving more weight to the green channel.

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.

Why is it called the fediverse?

Converting strings and characters between lower and upper cases is a very common need.

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.

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.

Unlike Ext4, Btrfs does not support encryption [...]

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.

The 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 ps xaf.

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.

Good question, anyhow.
