I have so many thoughts and feelings about that Gaza peace deal and everything surrounding it's but then I saw a Gazan journalist post on Instagram "the genocide is over" and I realized my thoughts and feelings don't fucking matter.

Not the main point of the article, nor the main problem, but now I have to add "but not those people" to my "does digital security work for vulnerable people".

I didn't manage to register to vote in the upcoming Dutch elections which is kind of okay, as I've not lived there in almost two decades, and kind of not, as the country has some crazy politicians and also, I myself tend to have political views that I 100% agree with.

I think also they have historically avoided team codes that are already used as country codes (hence also TBV).

Yeah, I was clearly told this by a CBP official when I ticked the 'tourism' box because my first destination wasn't the conference I was going to attend.

A poster that says: Behind the scenes of comics translation: A case study of two panels from fenta's comic Our Home, which you can find in our upcoming anthology. Then there's a partial mockup of the anthology book, a "live on Kickstarter" text label and the Paradise Systems logo.

I work in press freedom. The news is bleak, and I know journalists feel it too.

I hope you will support the news in whatever way you can to ensure they can do the work. It’s not their fault things suck, they’re just working their asses off to help get you fact checked information. Get them paid.

Tunisian sentenced to death for Facebook posts criticising president A Tunisian man has been sentenced to death on charges of insulting the president and assaulting state security through posts on social media, the head of the Tunisian League for Human Rights and his lawyer said on Friday.

There are many self-obsessed autocrats around the world. In Tunisia someone got sentenced to death for a Facebook post critical of the president www.reuters.com/world/africa...
The "oh, but actually we're a really civilized country" responses are fairly unique to the United States though.

Article reads:
Woman named as Archbishop of Canterbury in historic first 

The 63-year-old archbishop-designate is married to Eamonn Mullally, with whom she has two children. Originally from Woking in Surrey, she was the UK's chief nursing officer from 1999 to 2004.

This article manages to name her husband before it names… her.

A scientist stands in front of an enormous contraption
"I created this device to test my theory that our entire reality is a simulation, but the readings I'm
getting suggest something much worse"

 "What?" Asks a second scientist.
"We're living in a cartoon!" Says the first.
 "Does it at least have a good punchline?" says the second.
 The fiorst scientist carefully looks over the data, then eventually replies "Nope"

Israel has just arrested Greta Thunberg and many others.

Statement from the Global Sumud Flotilla:

β€œPeople of conscience have been abducted. The flotilla broke no laws. What is illegal is Israel’s genocide, Israel’s illegal blockade of Gaza, and Israel’s use of starvation as a weapon.”

I was in Berlin so I joined this for a bit. It was impressive. It's embarrassing for us as a species that we still need to protest against genocide (I think I've attended anti-genocide marches in five countries now), but the alternative is staying silent and that's a million times worse.
