  • True, but there are also some legitimate applications for 100s of gigabytes of RAM. I’ve been working on a thing for processing historical OpenStreetMap data and it is quite a few orders of magnitude faster to fill the database by loading the 300GiB or so of point data into memory, sorting it in memory, and then partitioning and compressing it into pre-sorted table files which RocksDB can ingest directly without additional processing. I had to get 24x16GiB of RAM in order to do that, though.


  • I mean, there are plenty of wealthy immigrants here, but I would say there are probably more immigrant families from regular or (relatively) poor families around. Like, people with a regular income who are working a regular job, not your average finance expat from an English-speaking country on an all-expenses-paid expat package plus a neat half million bucks per year salary on top.

    That said, the non-expat immigrants I know are overwhelmingly from eastern European countries, so I wouldn’t be surprised if the acceptance policy is biased against non-Europeans. You don’t see many average working-class Americans around here unless they married a Swiss person.





  • I have tried hosting a Tor relay on a VPS in the past and it was bottlenecked by the CPU at barely 20MB/s, although to be fair this was without hardware AES. More importantly for you, the server’s IP started getting DDoSed constantly and a whole bunch of big internet services just immediately blocked the address (the list of relay IPs is public and many things just block every address on that list instead of only exit nodes). So any of your machines are probably at least somewhat up to the task (ideally if they have hardware AES support), but this is definitely not something I’d do on my home network.











  • Not sure what you’re trying to ask, are you asking if using sudo to sign in as a different user will make kernel updates take effect? If so, the answer is no.

    Linux is an operating system kernel, which basically means it’s a program which runs other programs inside of it. For any “normal” program running inside Linux, you can update it by installing the new version and then exiting and relaunching the program so that the installed updates take effect. Similarly, after installing the Linux kernel itself, you have to exit and restart the kernel in order for the update to take effect. Because the kernel runs programs inside of it, exiting the kernel means all of those programs will be exited as well, and because the kernel is the only program running directly on the hardware, exiting the kernel means that your computer will power off. In simpler terms: getting kernel updates to take effect necessarily means you need to exit the old kernel and launch the new one, and there is no way to do that without reboot.
