Fox chirality!

Do foxes obey Bose-Einstein statistics, in which case their spin quantum numbers would be +1 and -1, or do they obey Fermi-Dirac Statistics, +1/2 and -1/2?

If the latter, it is possible that the fox is a Majorana fermion, in which case a fox of the opposite spin would be its antiparticle.

HKDF is commonly used to derive key material just in time for its application. However, as a cryptography tool, HKDF is severely under documented and lacks prescriptive examples for intended use.

A large-tech blog shared their HKDF application and I identify several issues with its implementation. Inside is an anonymized version with critiques and improvements.

How extremely convenient that IBM Research found a colorblind friendly color palette that includes roughly the colors of the bi pride flag :sparkles_bi:

Petite astuce si vous souhaitez faire basculer votre TIC en mode standard sur votre compteur Linky en étant client.e EDF:

Contacter le 09 69 32 15 15 puis choix 1, 2 puis 4.
Si le conseiller ne connait pas la procédure, dites lui de faire une F185 sur le site SGE en choisissant le mode standard. Préciser que la procédure a été confirmée précédemment avec le groupe TD.

Appeler de préférence en période creuse (temps de midi par ex). Normalement, le changement devrait être effectif la nuit suivante.

New blog post where I show a silly way to utilize Intel's AMX AI/Machine-Learning matrix-instructions to get the average color of an image.

A DICOM image.

DICOM is the medical image format, very TIFF-like.
Its preamble makes many polyglots possible, including TIFF-DICOM sharing the same image data.
It doesn't tolerate appended data - but just append a "private" tag if needed.

Note this is a choice some IT person made years ago and nobody realizes is optional, or something is actually broken and people just got used to it. Re-Auth could be entirely seamless if they wanted, or only enforced for certain apps. This is not intrinsic.

Something I see a lot is people accepting bad IT experiences as mandatory. Like this is life, get on with it. But this isn't remotely true.
It's a choice, sometimes just not a choice an organization realizes it has. I have to be the person calling bullshit on stuff because I know. Because I understand what's normal outside the org, or I have literally done their job before as an IT Generalist.

The business malaise in accepting deteriorated user experiences is frankly shocking.
You're being led like a dog by people who aren't being challenged to do better. Who often are not stupid and can do better, but have no mandate to venture it.

Ah ! À partir de demain un 02 ne sera plus forcément un 02 #téléphone #arcep

« A partir du 1er janvier 2023, les contraintes géographiques des numéros 01 à 05 s’assouplissent. Concrètement, il sera possible de conserver son numéro de téléphone fixe, notamment en cas de déménagement, dans une autre zone géographique de France métropolitaine. »

A very interesting take on the universe as seen from the perspective of the 2m amateur radio band by the #LOFAR radio telescope.

In 1959, the IBM 1401 computer was built from boards called SMS cards. A single board might hold just 3 logic gates so the computer needed thousands of boards. Silicon transistors weren't popular yet, so they used germanium transistors. Source: righto.com/2021/03/germanium-t… #history #computing

We have to deromanticize community. It's not some pristine untouched forest of soft moss and good vibes. The corporations count on that misconception to stripmine us for content.

Community has always been as weird and messy as humans are. It's work. It's relationships. It's hard. There isn't a magic number. They aren't inherently anticommercial. They don't all look or act the same.

That's one of the reasons I wrote this and am driven to write more: powazek.com/posts/3571

I slept very poorly last night due to the news that Musk gave privileged / possibly PII & DM level access of Twitter mod access to a variety of strident anti-LGBTQ (especially anti-trans) bigots who masquerade as journalists. This is an incident which would require user notification under California law, if it weren’t for the platform owner granting it. It still might be a violation of privacy laws. It’s absolutely a disaster for all LGBTQ people who used Twitter.

In August 2011, Los Alamos techs posed 8 plutonium rods on a work table to take a few photos.

Had these rods rolled into each other there would have been an instant criticality event. (Think "Demon Core")

Worst still, a supervisor who saw the display ordered the techs to safe the rods, ignoring the protocol to evacuate EVERYBODY (b/c even a hand could moderate the neutrons & cause criticality).

It caused a 4-year, billion-dollar shutdown.

...

Smart people + overfamiliarity = stupid things.
