talk about a support chatbot

I spy on the dev support channels at work (a ticket is created for every top level thread), and they connected a bot that attempts to answer questions by matching against previous problems and our internal documentation, and tbh it works really well. I've seen it give the correct answers a lot of the time. (And irrelevant ones occasionally.)

Minnesota Dems are trying to elect as governor, the County Attorney that refused to charge Derek Chauvin for his entire career of brutality against Black Minnesotans, and refused to charge almost every cop in the police department that is on the most racist 1% of police departments in North America?

Then if Black Minnesotans don't turn out to vote for her in record numbers, a bunch of white people are going to jump on BlueSky and Twitter and Mastodon and Facebook to curse out Black people, and express their homicidal fantasies about how Black men and Somali immigrants now deserve whatever is about to happen to them.

Chart showing Minnesota has "More Racial Disparities in deadly force than 100% of Depts"

That is not a good accomplishment.

Only 19% of Minnesota is Black, but 75% of people killed by police are Black.

i think a lot of devs just can't really comprehend the kind of relationships non-devs have with computing. which like, fair, it's difficult. but i think there's a lot of weird beliefs that come out of this for sure. anyway just to be clear, agreeing with you, just in a rambly way

Someone, some time ago, made a web "app" to play music or maybe video, I think, with iframes, and web standards - no funky Frameworks or YouTube embeds.

Does that sound familiar? I'm sure there was either a good string of posts or an article about it.

1. Managed to get Pebbles the (Formerly) Semi-Feral Cat off to the vet to check on a gunky eye. She didn't even scratch me which is a first
2. The eye isn't too serious (good) and can be treated with eyedrops. I was worried it might be something worse as weepy eyes are often first sign of that.
3. I managed to administer Pebbles eye drops all by myself tonight. Again, she didn't scratch me and she seems quite chipper

(Photo is a before photo because she really doesn't need people seeing her gunky eye tonight)

A calico cat is lying on a bed, resting its head on a duvet. The cat's eyes are slightly open, and its front paws are tucked close to its body. The background features soft bedding with a floral pattern

Does anybody remember when the Amazon algorithm used to be really good at suggesting things? I'm talking back before you'd look at one back scratcher and then the whole For You page would be nothing but back scratchers? Like, I remember a time where like my entire purchase history was clearly being used and I was getting suggestions that were basically "people like you were also interested in..." and it regularly had stuff I didn't know existed and was interested in seeing. Now...yeesh.

just did some searches on postgresql upsert to check on some details.

saw some tutorials talking about `MERGE` as an alternative to `ON CONFLICT DO`

thought "what is this? postgres doesn't have something called `MERGE`, great i must be reading LLM-hallucinated tutorials"

look around some more... huh... postgres added MERGE in version 15 🤯

Unless the "AI" bubble bursts in the next six months, I don't know if I can stay in tech any longer.

Yeah, the code is going to keep getting worse, so there will be opportunities to do secure code review.

But how many people are going to have their brains addled by "AI psychosis" and will be even more insufferable than they are today?

I understand more and more every day why people leave tech and become farmers.

Climate Wars by Harald Welzer, 2024

What People Will Be Killed for in the 21st Century

Struggles over drinking water, new outbreaks of mass violence, ethnic cleansing, civil wars in the earth's poorest countries, endless flows of refugees: these are the new conflicts and forces shaping the world of the 21st century. They no longer hinge on ideological rivalries between great powers but rather on issues of class, religion and resources.




The genocides of the last century have taught us how quickly social problems can spill over into radical and deadly solutions. Rich countries are already developing strategies to garner resources and keep 'climate refugees' at bay. 
In this major book Harald Welzer shows how climate change and violence go hand in hand. Climate change has far-reaching consequences for the living conditions of peoples around the world: inhabitable spaces shrink, scarce resources become scarcer, injustices grow deeper, not only between North and South but also between generations, storing up material for new social tensions and giving rise to violent conflicts, civil wars and massive refugee flows. Climate change poses major new challenges in terms of security, responsibility and justice, but as Welzer makes disturbingly clear, very little is being done to confront them.
