#TIL When a Class 2 ceramic capacitor is heated above its Curie temperature (130 °C), the crystal structure changes. Soldering the cap causes a sudden increase of capacitance beyond spec (so don't attempt to hand-matching ceramic caps!), followed by a logarithmic decline (aging). This is reversible, resoldering the cap or baking the board can "reset" an aged cap back to the initial state.
"Referee time" is the time for a cap's capacitance to decline back to its standard spec value (X7R cap ages slowly, referee time is 1,000 h., X5R is only 48 h.). A DC bias not just reduces the effective capacitance, but further accelerates aging in a nonlinear way.
As usual, Class 1 NP0/C0G capacitors are not affected by these effects. #electronics
@fluffy I'd be pretty pissed if they did that to a train station I used often.
Both proprietary and free software users care about their privacy, but free software users are actually empowered to *protect* it. They can audit the code and, if they have to, remove any questionable bits and still use the software. https://puri.sm/posts/audacity-telemetry-and-why-free-software-means-better-privacy/
redditors: why did they drop this microcurrency without any prior announcement
because they knew people would hate it. corpos always do this.
pre-news is for hype train, sudden “and now here’s the feature where you have to wear our butt plug and let our spies live in your attic” is to prevent counter-hype trains.

@icedquinn @thor @paul My favorite feature of my ukuleles is that there's no software.
@fluffy This is my haircut. My gf picked it after I cut my bangs short once.
Manjaro with Plasma mobile has seen major improvements! Here I review it on the recently released Pinephone BETA Edition.

@joeligj12 Windows sets the hardware clock to local time and Linux sets it to UTC.
IMO: you're much better off running windows in a VM as that contains the malware (firmware/bootloader overwriting crap) Microsoft ships in windows update.
@valleyforge Or better yet, throw out http/https and just use ssh since that's what modern http is evolving toward anyway.
@valleyforge Websites should just use mtls.
@fluffy Isn't that what ymacs is? I'm pretty sure that's also what the iPhone "emacs" app is.
Installing postmarketOS on the LG K10 :D

Email mastodon+swiley@swiley.net (this makes all of my computers beep and turn on an indicator light and is always the fastest way to reach me.) I was on octodon a while ago but abandoned my account. I've never been a member of gab or parlor.
If you’d like to learn to program I would consider the SICP [1] more or less the peak of American CS pedagogy (at least as far as beginners go) along with “The Practice of Programming” once you get through that.
I play ukulele, I’m ok at reading music and decent at improv. I learned from Walter Piston’s “Harmony” and some of Adam Neely’s videos.
My main phone is a pine phone so if I don’t pick up when you call the battery is probably dead, the modem is probably dead, or I’m currently swearing at calls/pulseaudio/alsa. I’d strongly recommend sending an email instead.
Dispite what my web page says I’ve stopped uploading my scratch projects to GitHub once I started to understand the basics of collaboration with git. I was using the flamegraph as gamification/motivation but it doesn’t work as well with feature branch/squash merge workflows so I just keep most things on my VPS until I’m happy with publishing updates.
