I cannot stop thinking about how a century of speculative fiction about catastrophic rogue AI meltdown became a self-fulfilling prophecy by building an AI that functions by running a probabilistic lookup on a table of all fiction humans have ever written to determine what the average AI would do in the current situation

Great example of "when switching to a different general purpose allocator affects performance, your memory management strategy sucks".

The Rust compiler seems to do an absolutely insane amount of heap allocations.

Chatting to someone who seems to be obsessed with 'boosting' their immune system.
"You can make your immune system work harder by doing this and getting it to 110%"

Sir, if my immune system is working 110% that is called an autoimmune disease

Sent a pull request to Audacity fixing a crash bug I'd been running into frequently. The cause was an out-of-bounds memmove. Classic C++ areas.

Anyway I got a fucking copilot review on my PR which left two comments, both completely wrong, one of which suggesting I reintroduce the out of bounds memory access. I'm furious!

It’s important to remember that #Pride is a protest. Rights are won, not given, and must be defended. #BudapestPride Budapest Pride ban at centre of Orbán's culture war https://www.rte.ie/news/europe/2025/0627/1520536-budapest-pride-ban-orban/

Today in vendors slipping single bits (or single bit!) of information into weird places:

I am *completely* certain that Google once made a USB-C audio adapter that has a *different USB PID* depending on whether it has something plugged into it.

I am somewhat certain that it's 18d1:5025 with something plugged in, and 18d1:5029 without.

If anyone has this adapter and is interested in this useless research, please send screenshots lsusb or device manager for this. Thank you so much. I need this.

@malwaretech @glyph unfortunately, chain-of-reasoning is just as much hallucination as everything else, so asking how it knows something only yields answers that *could* plausibly be how one knows something. However, it is known that the major chatbot systems receive information about the current user in the background, which could include not just what you’ve deliberately provided (such as your username) but also the profile of you built up by ad networks.
@gsuberland Maybe CPPFLAGS instead of CXXFLAGS?
I got a text from a "lawyer" saying they had trademarked my business name and I had to either pay them or "cease using the name immediately." I googled the phone number and it came up associated with a group of scammers so I screen shot that with a "This you?" message. He responded, "Have a blessed day." 🤣

tell all your neighbors

ring is gonna start feeding your video feeds to their AI

@Viss

They're going to train _their_ AI models on your footage.

They're going to invite you to correct their generated text in order to better train _their_ AI model.

They're not going to ask for your permission.

@Viss Walking into dystopia through luxury surveillance, we are.

And when the tech giants have enough power, they’ll pull the ladder up behind themselves.

@Viss

Everything Amazon got tossed a couple of months ago. They are a privacy nightmare.

@Viss Someone needs to make a business of converting ring cameras into butt dildos.
@Viss this was always the plan. It was always obvious, if one was paying attention
@Viss
How high fidelity does a print need to be for Nightshade pixels to remain effective at the resolution of a Ring camera? Asking for a friend.
@caranea THAT is a good question >:D - these things arent super highres, so i imagine it will take some trial and error
@Viss They’ve been feeding that info to the cops without a warrant for years. We’re a capitalistic surveillance state where everyone was taught to be afraid of their neighbors and, preferably, armed.
