the fact that discord can use 1.5GB of memory WITHOUT having a memory leak is frankly unacceptable and anyone who helped make it that way should be ashamed of themselves tbh
One for the history books...

Amazing how many headlines parrot the corporate framing that Meta's new Hyperion data center would "deliver gigawatts of power" -

"AI data center ... will deliver five gigawatts of computational power to fuel the company's new AI" ❌

"[data center will] supply its new AI lab with five gigawatts of computational power" ❌

No. NO. Don't do that. Hyperion will *consume* 5GW of power, including three NEW new gas-turbine power plants, in order to run giant toxic content sludge generators. 💩 ✔

For many people, the #Linux vs #Windows vs #Mac debate is a privilege — it assumes you can choose. But working with the Computer Upcycle Project, I've seen the real choice is often Linux vs no computer at all.

~95% of donated computers are "too old" for Windows 11 or macOS. Linux installs on them anyway, adding 10+ years of life to machines #Microsoft and #Apple called trash.

This isn't Linux vs Windows. It's Linux vs e-waste.

I want to teach a class on repurposing electronics. We could start out just taking some broken things apart and seeing if we can fix them, but every student would have to pick something to repurpose or revive as a semester-long project. Maybe they want to turn an old propane lantern into an LED lantern, convert a cordless drill with dead nicad batteries to lithium, or jailbreak an e-bike. Everyone should leave the class with a device or appliance with a new lease on life. A community college should hire me for this

Physical security and cryptography can learn from each other, part 11367:

Hotels wisely don't put the room number on guest keycards so if someone finds your card, they'd have to exhaustively search the hotel to find the room it opens.

Some hotels now have elevators programmed to only let you call the floor for which your keycard is coded, preventing guests from wandering to other floors.

But it also means the elevator can be used as an efficient oracle to determine the floor of a found key.
