Al Jazeera has the story of a Moroccan footballer who died trying to reach Ceuta and while her story is one of many, that should be our focus. Not Schengen or Spanish politics aje.news/aci1rp

Trump having a normal one today
I'm not normally one to enjoy dystopian fiction (I subscribe to several newspapers for that and even there "enjoying" would be a stretch) but "I Who Have Never Known Men" by Jacqueline Harpman is eerily good.
This week I read Miranda July's "All Fours". It kinda blew me away.
My phone sent me a breaking news alert "US announces nuclear..." and I've never been so relieved about uranium enrichment.
Imagine the UK govt made a strong statement condemning the Scattered Spider kids who just got sentenced but also, not quite subtly, hinted at how their amazing skills were a result of the British education system. That's how I read posts from AI companies talking about AI used in cyber attacks.
There was a seven hour power cut today and an awful sewage smell in town afterwards so here's your reminder for a post-electricity world: don't leave food in your fridge.
i need people to talk to me with the clarity they reserve for their most expensive prompts
Over the years I have, even I say so myself, become reasonably skilled at recognizing threat infrastructure from scanning data. I have not yet mastered the skill of recognizing a funny feeling as 'I need to eat'.
One more thing about the World Cup: I remember seeing a video of huge celebrations in Eastern Congo after the DRC made it to the second round. That alone made having 48 nations compete worth it.
There just was a power outage that lasted several hours. Street lights were off, most traffic lights too. It was eerie. Anyway, I decided to ask chatgpt what causes these outages, and
I thought Italy boycotting the World Cup by not qualifying was classy, but making it to the final and then doing this, now that is a statement.
In fairness, it has been close. #ESPARG | #FIFAWorldCup
I am watching a bit of the final while getting takeaway pizza and I realize I'm still not over Cabo Verde and Egypt. I want Spain to win mostly because I want them to lose the least. (Okay and Lamine Yamal seems kinda cool.)
Could Excel be conscious? We surveyed more than Jan 1 1900 people to find out.
Racism in, racism out.
Ontario jails are using an AI tool that claims to predict prisoners’ behaviour. And it’s disproportionately placing Black prisoners in maximum security. An investigation by @desmondcole.bsky.social reveals the province knew the tool would discriminate against Black people—and used it anyway.

"I hope that this shares with people that are incarcerated on Rikers, that they too are a part of this city. The World Cup has been a magical moment for the entire city. These are New Yorkers, and they will be New Yorkers when they get out of Rikers. They are New Yorkers today." ♥️♥️♥️

The beautiful game. The people’s game. Throughout this World Cup, we have been reminded of a simple truth: football belongs to everyone. So does the joy and community it creates. Yesterday, I joined New Yorkers on Rikers Island to watch England take on Argentina.

I'm an optimist so I think that maybe SS7 being used to track US military (rather than, say, journalists or activists) will help fix that gaping hole techcrunch.com/2026/07/14/i...
