Lead-based solder is preferred for high-reliability electronics (space, nuclear, military, etc.) because it’s easier to rework, easier to verify by visual inspection, and it’s not vulnerable to tin whiskers.
I’m an electrical engineer living in Los Angeles, CA.
Lead-based solder is preferred for high-reliability electronics (space, nuclear, military, etc.) because it’s easier to rework, easier to verify by visual inspection, and it’s not vulnerable to tin whiskers.
Here’s the relevant safety guides from Stanford and MIT.
In short, if you do a lot of soldering, there are long-term occupational hazards from both lead oxides and rosin. Both guides agree that the main hazards are the fumes (workstation should have a fume extractor or suitable filter) and residue on your hands (wash hands with soap and water before eating).
I couldn’t find any numbers on how much material is removed by washing, but every reference emphasized that soap and water are vitally important.
“WAAAAAAAAAGGH!” is what the 10-foot monster yells while charging at you.
Does that require admin access? It wasn’t their machine, it was one the school provided for the auditorium.

I saw that happen once in a big presentation.
There was a team of students presenting their work to ~200 people. Right in the middle, a pop-up says updates are finished and the computer needs to restart. It has a helpful 60-second countdown, but “cancel” is grayed out, so all they can do is watch.
I was only in the audience and I still have nightmares.
Doesn’t the ESP32 module this project is using require the same thing?
It works for now on x86-64, yes. For now. As always, we are one “think of the children” crisis away from lobbyists taking that option away.
It’s not for you, it’s for them. Secure boot means it only runs their operating system, not yours. Trusted enclave means it secures their DRM-ware from tampering by the user who owns the PC.
This is the mental equivalent of Saitama’s workout from One Punch Man: 100 sit-ups, 100 pushups, 100 squats, and a 10-km run. (Repeat daily until your hair falls out.)
I’m speculating, but my guesses are:
Once mature, it’s usually used for spam or astroturfing. There is a noticeable uptick around big elections, wars, etc.
I saw one repost-bot that metastisized into the most vile porn-spam-bot you can imagine, but they’re usually more subtle than that.
They’re indistinguishable because they’re copied from top-voted posts that are a few years old (title, text, and image if applicable). It’s guaranteed to produce a post that fits the community and gets a lot of engagement, so it’s a cheap and effective way to mature a bot account. Once you start looking for it, it’s everywhere, and Reddit admins don’t care.
I always thought it’s because vacuums crave the souls of cats and dogs. TIL.
The healer in Tactical Breach Wizards is a necromancer, so she can only fix you up once you’re dead. She carries a .45 for medical purposes.
Important question: Should dragons be equipped with explosive reactive armor?
SATA= Slow (Max 6 Gbps) PCIe = Fast (Max > 100 Gbps in theory)
This is the maximum rate from the drive to the motherboard. Many drives are fast enough that SATA works become the bottleneck. With PCIe, the drive can run at its full speed, whatever that may be.
Now explain PartialEq, and why it’s mandatory.
