You mean SNI, not ESNI. ESNI is the Encrypted Server Name Indication that gets around that, though the newer ECH (Encrypted Client Hello) is better in many ways. Not all sites support either though.
You use the cleaning function first, then the dry function. Don’t just dry the shit on there (well, maybe you would, but everyone else washes first, that’s the point of a bidet).
Negative absolute temperature is a thing. Lasers exhibit negative temperatures when active, i.e. the lasing medium has a negative temperature expressed in Kelvin. Adding more energy doesn’t increase its entropy, it just turns into more laser light. Any such system with bounded entropy can have a negative thermodynamic temperature.
Copper or silver-based should be lower resistance. These conductive paints tend not to be very conductive, the carbon stuff is essentially making a thin-film carbon composition resistor. Good for repairing rear window defroster heating elements, not so great as a 0-ohm trace in a keyboard. For short (<1cm) wires it’s usually not too bad, but with the amount of damage I’m not sure you’ll be able to repair the thing.
It looks like it might be from a Model M-style keyboard. Unicomp sells those.
If there’s more activity on Reddit then here, then Reddit repost bots make it feel like all the community action is happening on Reddit. They push people back to Reddit because that’s where all the new posts are coming from, so why engage here if the active discussion is already in progress over there?
The Internet corollary to Murphy's Law: If you post something, it's public forever unless you need it later, then it'll have link-rotted. Anything you want to delete will be archived, anything you want to save will be deleted.
The “isn’t huge” is the issue. Linear supplies need a rather big transformer to work with 60Hz mains instead of chopping it up at 20kHz or more like switchers do. I’ve got a Siglent SPD 3033X-E (decent, reasonably cheap) and a BK Precision 9201 (better, more expensive).
The small supplies are nice for size, but tend to have more noise than the big linear supplies. If you’re working with low-precision DC circuits, or even stuff up to audio frequencies (basically still DC) it’s not likely to be an issue. If you’re working with RF circuits it’s more likely to be an issue, though of course if they’re not too close to the switching frequency it’s easy enough to filter the output.
Also bleeding-edge processes mean smaller, thinner gates. That’s what gives them the fast switching speeds, but it reduces the max allowable voltage. For parts that need to handle more than 1.8V or so a modern 5nm process will just end up using bigger gates than the process is optimized for. May as well go with an older process (bigger minimum gate size) that’s better suited to switching the voltage needed. For Bosch (automotive parts, power tools, etc) they’re making a lot of parts with really big output transistors (switching 14V, 48V, etc) and not super high-performance processors.
The big disadvantage with particularly old processes is that they used smaller wafers. So fewer chips per wafer processed, meaning lower overall yields and higher price/chip. The switch from 200mm wafers to 300mm in 1999 meant the wafer area increased by a factor of 2.25! 300mm wafers also required fully-automated factories due to the weight of a wafer carrier (a front opening wafer pod, or FOUP, is 7-9kg when loaded with 25 wafers), which save on labor costs. So processes older than 1999 (around the 180nm node) are sometimes not worth it even for power electronics.
