Related to the latest round of everyone finding out what happens when you write image decoders in C++ now known as CVE-2023-5129: you may want to update every electron app on your machine as much as possible. Electron is built on the foundation of Google Chrome and it turns out that the webp vulnerability is also present in Electron. Annoyingly, this is going to require you to figure out which vendors have patched their apps for the vulnerability. Good luck.
You probably should update Discord immediately.
Hm~ on the off chance it's obvious to someone: I'm trying to use the built-in I2C hardware in STM32Lsomething. I use RIOT-OS's library for interacting with that I2C hardware, and what happens is that as soon as the pins are switched to the alternate function of I2C they get pulled down (afterwards it seems that no I2C operations ever complete, but that's not that weird considering this messed up initial state). Is there something obvious I could be doing wrong, or something I ought to check?

Mam wrażenie, że bezrefleksyjna powszechność zwrotu "głosowanie za kimś" powoduje podobnie dużo szkód jak "aresztowanie za coś".
Powszechny jest pogląd, że głosowanie polega na wybraniu kandydata, którego najbardziej chcielibyśmy widzieć wybranego. Nawet w przypadku wybierania jednoosobowego organu nie jest to sposób, w który najlepiej możemy realizować nasze preferencje (nawet nie może, bo nie zależy od tego, których z pozostałych kandydatów wolimy bardziej). W przypadku organów wieloosobowych sytuacja jest jeszcze bardziej skomplikowana, bo przestrzeń możliwych preferencji jest większa.
IMO warto myśleć o głosowaniu nie jak o wyrażaniu poparcia dla konkretnego kandydata, ale jak o wyborze, który ma skutki. Jeśli mamy do dyspozycji rozsądnie dobre przewidywania wyników wyborów, możemy poszacować jak każdy możliwy wybór może wpłynąć na wyniki.
Eh, chyba powinienem po prostu napisać taką symulację i ją udostępnić.

Today was ... interesting. If you followed me for the past months over on the shitbird site, you might have seen a bunch of angry German words, lots of graphs, and the occassional news paper, radio, or TV snippet with yours truely. Let me explain.
In Austria, inflation is way above the EU average. There's no end in sight. This is especially true for basic needs like energy and food.
Our government stated in May that they'd build a food price database together with the big grocery chains. But..

@samwho Rust is even more aggressive about some of this. You'd have to Pin<> things at a minimum, and that may not be enough. And any code that involves Pin<>s is usually a pain.
Put your secrets in a different address space, ideally in a different processor entirely.

The physics of why the first clock in America failed
The first clock in the Americas was an abject failure.
Little did everyone know that gravitation was to blame.

@msuriar tbf HAVING and WHERE being two different language elements is absurd.
Consider trying out https://prql-lang.org/ which compiles to readable standard SQL and doesn't have such issues :)

We have a wonderful Slack channel called #why which is filled with questions like "why do we do <thing>" or "does anyone remember why we do <thing>"
1. It's kinda helpful when you scale up staff by 100% in approximately one year
2. Even the CEO asks why questions!
3. At year 6 or so of a startup there are lots of decisions to be reconsidered

Some people, when confronted with a key management problem, think “I know, I'll use a Public Key Infrastructure.” Now they have a Problem Authority.

@harcesz "The name and logo of "NERV" are used with the explicit permission of khara Inc., the copyright holder of the "Evangelion" series, and Groundworks Corporation, which manages the rights to the series."

Przez chwilę myślałem, że to jakiś nieoficjalny dostęp do danych z aplikacji NERV (heh*), ale wygląda na to, że to jednak zupełnie oficjalne działanie agencji odpowiedzialnej za tą usługę;

Wygląda na to, że w sumie prowadzą ponad 230 kont na mastodonie, tak że można precyzyjnie dobrać preferowany typ ostrzeżeń a dodatkowo najważniejsze są podbijane przez wszystkie konta regionalne w zasięgu - sprytne rozwiązanie. Usługę uruchomili w 2017.
*Czy jakaś bardziej japoniofilna osoba może mi wytłumaczyć - czy Japończycy faktycznie nazwali agencję ostrzegającą przed katastrofami za, oraz skopiowali logo/motto agencji konstruującej roboty do obrony ziemi z popularnego anime?

I know corporations are evil but I'm still quietly impressed at the LEGO group's tax policy (namely - to pay them, make sure to pay them and to acknowledge that taxes are a core part of giving back to society and corporate responsibility). The corporate income tax rate in Denmark is 22%, and 22% is what they pay on their gross profit. The tax policy document is a short but informative read (see link).
Compare this with Google, Amazon and friends, who constantly trumpet their social responsibility but who are somehow only paying a few percentage points of US federal income tax on their own profits.
And yet Lego continues to make generous net profits and has not been taxed into oblivion as conventional thinking in the US would consider inevitable.

Why would one ever want to use `nix-env` on NixOS? It causes a lot of confusion for new people when they realize that what needs updating is not only channels of their user, and channels of root, but also nix-env-installed packages. Even once you resolve that confusion, you are still stuck with one more independently updated thing that you need to update in sync (due to graphics drivers), so the promise of easy rollbacks is a bit further away (because one needs to roll back one more thing and remember to do that).
