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.
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.
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.
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.
Every time I see “lichess”, it makes me think about “lich-ess”, i.e., a female undead wizard.
Sadly, Firefox mobile got rid of about:config, and I can’t find any relevant options in the regular settings.
You can disable this “feature”:
Visit about:config
Set “dom.private-attribution.submission.enabled” to false
Sure, but there’s still no excuse for “store the password in plaintext lol”. Once you’ve got user access, files at rest are trivial to obtain.
You’re proposing what amounts to a phishing attack, which is more effort, more time, and more risk. Anything that forces the attacker to do more work and have more chances to get noticed is a step in the right direction. Don’t let perfect be the enemy of good.
No, defense in depth is still important.
It’s true that full-disk encryption is useless against remote execution attacks, because the attacker is already inside that boundary. (i.e., As you say, the OS will helpfully decrypt the file for the attacker.)
However, it’s still useful to have finer-grained encryption of specific files. (Preferably in addition to full-disk encryption, which remains useful against other attack vectors.) i.e., Prompt the user for a password when the program starts, decrypt the data, and hold it in RAM that’s only accessible to that running process. This is more secure because the attacker must compromise additional barriers. Physical access is harder than remote execution with root, which is harder than remote execution in general.
Full disk encryption doesn’t help with this threat model at all. A rogue program running on the same machine can still access all the files.
Is this why Ian McCollum’s videos are getting altered? Over the years, he’s had many historical deep-dives featuring firearms from the Murphy’s auction house. In recent months, he’s been re-uploading those videos to cover their logo with the word “Morphy’s”. Even though the auctions are long over, I suppose Google counts them as promoting sales.

This isn’t funny, this is just the sad state of software these days.
Now explain PartialEq, and why it’s mandatory.
