Uh yeah, I’m pretty sure the discharge can stop your heart if you grab it in precisely wrong manner. Typical defibrillator uses like 50 times less energy, but with a higher voltage.
A capacitor of 1 farad at standard American 120 volts has the energy between 7.62×54 and .50 BMG, and will discharge just as violently.

The truth is people who want small phones also want them for the price of a clamshell feature phone with no 4G support. I’ve heard these complaints many times from older acquaintances, they want their old Nokia that can also run Viber and do videocalls, and they are not paying iPhone SE price, so there’s practically no market for small but high-spec phones, outside of luxury brands where you are buying an ancient chip with a leather back cover.

Electron was discovered in 1897. If you own a textbook on chemistry which is older than that, put it up on Ebay in the antiques category.
The ingenuity of this command is that
/dev/nul
does not exist, the correct path is/dev/null
, however the command executes without error and creates a symlink to a non-existing path.

Yeah, cheap cable and cheap charger won’t provide 35 watts of power. However that cheap 24-pin Type-C cable costs the same as 5-pin Micro-USB cable did in 2010, and you can use your old Type-A charger with it, so you’ll getting your 5 volts 2 amperes everywhere, and did I mention that the connector is reversible?
mcedit, because I’m not nerdy enough for vim.
pelya@lemmy.worldto Selfhosted@lemmy.world•What are the benefits of a server having multiple public IP addresses?English7·1 个月前Because you won’t determine the type of NAT during hole punching. This requires the client sending two UDP packets to two different IP addresses, then comparing their source addresses on the server.
Normally yes, you can just assume that two clients you are trying to connect both have port restricted cone NAT, and run the hole punching algorithm, and if the connection fails after ten seconds, show message to the users ‘Error 418: your router is a teapot’.
pelya@lemmy.worldto Selfhosted@lemmy.world•What are the benefits of a server having multiple public IP addresses?English41·1 个月前The one use case is running STUN/TURN server for NAT hole punching, that requires two separate servers, or one server with two IP addresses. You will only need that to run masterserver for games that support hole punching, or to run VoIP telephony / teleconference server.
Another use case is reliability, when your server is connected to several network providers, it will keep working if one of them has an outage, and will naturally have a different IP address for each network link. But your VPS does not have several network links, otherwise they would advertize that in bold red letters.

Nope, Linux kernel used in that tech demo is for RISC-V architecture

pelya@lemmy.worldto Android@lemdro.id•Google says Android 16's new desktop mode builds on 'the foundation of Samsung DeX'English3·2 个月前Yes, Android is a (extremely heavily forked) Linux distribution.
Well ackshually Android kernel nowadays is built from an upstream unmolested Linux kernel sources, straight from Torvalds’ git repository.
And the rest is just the init system, which is not systemd so it’s better by definition even though it’s written in Java, and a display server written in Java, because there was no Wayland when Android development started.
Democracy works exactly as intended. Dumb voters chose dumb leader. It would be another case if dumb people were a minority, or at least didn’t flaunt their idiocy by voting for the dumbest option available.
