  • In first you need understand what type of suspend you use:

    Suspend to RAM (aka suspend, aka sleep) The S3 sleeping state as defined by ACPI. Works by cutting off power to most parts of the machine aside from the RAM, which is required to restore the machine’s state. Because of the large power savings, it is advisable for laptops to automatically enter this mode when the computer is running on batteries and the lid is closed (or the user is inactive for some time). Suspend to disk (aka hibernate) The S4 sleeping state as defined by ACPI. Saves the machine’s state into swap space and completely powers off the machine. When the machine is powered on, the state is restored. Until then, there is zero power consumption. Hybrid suspend (aka hybrid sleep) A hybrid of suspending and hibernating, sometimes called suspend to both. Saves the machine’s state into swap space, but does not power off the machine. Instead, it invokes the default suspend. Therefore, if the battery is not depleted, the system can resume instantly. If the battery is depleted, the system can be resumed from disk, which is much slower than resuming from RAM, but the machine’s state has not been lost.

    I think you use Hybrid suspend. Hybrid suspend store memory to disk (20 seconds lag) and then lost battery for memory renew. Need you Suspend to RAM maybe? 20 Seconds lag will fixed with that.

    Then check

    cat /sys/power/mem_sleep
    

    If you see

    [s2idle] shallow deep
    

    check first if your UEFI advertises some settings for it, generally under Power or Sleep state or similar wording, with options named Windows 10, Windows and Linux or S3/Modern standby support for S0ix, and Legacy, Linux, Linux S3 or S3 enabled for S3 sleep.

    If you don’t see anything you can swap sleep mode to Suspend to disk. That slow but don’t use any power. Or try fix sleep status.

  • I think that in order to solve such a question, we first need to consider something else. Why, if votes are so important to you, can’t you just create a bunch of accounts and vote honestly on any server?

    As soon as we are really sure that 1 person is 1 vote, and not 10, 100, 10000 or any other number, then it is already possible to build trust checks between servers. Although it seems that this has not been solved even by large social networks.

    The answer to your question in general is this: store the votes by servers and then double-check the result randomly.

    S returns: 50 votes for a post from server A, 30 for a post from server B, 10 for a post from server C, etc. Then you can randomly check on these servers whether the amount is correct. However, there is no way to check the voices of server S, so they either have to be thrown out or still trust the server at its word. It is possible to fully verify server S only if registration on all servers goes through a trusted intermediary.






  • On DNS you need A record if you have ipv4 only or A and AAAA records if you have ipv4 and ipv6.

    You DNS outside you home servers? If you have dynamic IP at home you can’t host DNS on home server.

    You have only 1 IP? You need port forwarding on you home gateway to home servers if you use somerhing like SSH. If you want access to something web based you need proxy. NGINX for example.

    How it exactly work:

    • Somewhere someone write youdomain.com in browser.
    • Browser ask local dns: who is youdomain.com
    • local dns ask another dns, and another and in one iteration request go to you dns. Or maybe some of dns have cached answer. But imagine that not.
    • You dns send answer youdomain.com is 111.222.333.444 for example. That is A record.
    • DNS work stop on that.
    • Browser send request to 111.222.333.444 with HTTP header “Host: youdomain.com” and some path. / or /something maybe.
    • Some balancer should get request and send in to right server in you home network.

    UPD: don’t show to internet something risky interfaces. Proxmox web panel or something like that. This is a real bad idea. For that type of services VPN extremely greatest. Send you DNS to public without protection not a great idea too. Including pihole. I think you will get into some botnet already on the 3rd day of work.





  • ubuntu mate is a good choice for a beginner, but if your computer is old enough, the system may slow down. This is due to the fact that snap images are slowly decompressed on older processors. You can try Linux Mint too.

    About the software. The main thing is to accept the fact that not all Windows applications have analogues on Linux. some people actually make such a mistake. no need to try to install wine and migrate literally every exe file. Look at the software specifically for linux.

    The default browser is firefox. But you can install chrome or chromium without any problems. There is OBS studio for linux for streaming. For games, you can put lutris. There is also an official steam client. if the game has an anti-cheat and this anti-cheat is not optimized for linux, you will not be able to play it.


  • I don’t deny that systemd is easier than SysV. I say that on complex configurations it is not slightly simpler. Moreover, what I could do just in the sysV script, I now have to divide by tmpfiles.d and systemd. And sometimes even include processing both there and there, because depending on the version systemd has different behavior with parameters LogsDirectory= and RuntimeDirectory=. As a result, the dependence on the system has not completely disappeared for the package maintainer. Although of course there are a little less problems with systemd.

    On other side as a user, I don’t really like to guess exactly how a folder was created in /run, via tmpfiles or via systemd.

    UPD: On SysV I have one complex, heavy script. Now I have the systemd service, the tmpfiles configuration, the /etc/conf parameters file.d and there is still a shell script to run. But if user wants reconfig something he need look 4 files instead one.


  • Right. But on something more complicated than initializing the usual daemon, systemd has all the same problems. For example, if you have a java application and you want to dynamically manage java parameters and application parameters, the script will look like a pain. something like bash -c ‘java …’ or you will have to call a separate script in the initiator. And then to turn off the shell and switch to the application itself, there will be a whole adventure with pid generation.

    But sure systemd really more easy then system V.



  • you do know what the linux kernel is, right?

    I know that the core is monolithic.

    In the end your distro packager decided to not split systemd into different packages

    I installed these services myself, not all of them, of course, but those that I listed at the end. I know about the rest simply because I prefer to read the documentation for the services I work with. I’m not particularly happy with the systemd system as a whole. however, since there is no better alternative, the choice is small.


  • As I wrote below, the problem is that this does not comply with the principle of K.I.S.S. One application should solve one task and can be replaced. Even now it is quite difficult to remove systemd-logind, for example. Because, although these are different services, they have long merged into a huge tangle.

    I actually use systemd-boot because it’s very easy to install and configure and systemd-resolved, but for a lot of those I haven’t even heard about.

    you can use EFISTUB If you don’t have dual boot. This literally load kernel from UEFI. I don’t know more simple way. https://wiki.archlinux.org/title/EFISTUB
