    This plays some kind of role in the debate of systemd being good or not. I’m not sure if goes in the good column or the bad column, but I know it goes into a column.

      I am typically in the group saying “systemd is overlarge with too many responsibilities” but this capability makes perfect sense for its job running services. Probably the good column.

    In the UK, if Christmas or New Year falls on a weekend, a seperate equivalent holiday is made during the week to compensate.

      Same for lots of jobs here.

      Honestly, Wednesday and Thursday are the worst days for Christmas for those of us who also get Christmas Eve because they’re the only days that don’t result in 4 days in a row off from work.

      If it’s on a Friday, we get Thursday through Saturday. If it’s on a Saturday, Sunday, or Monday, they give us Friday through Monday, and if it’s on a Tuesday, they give us Saturday through Tuesday.

      But this year, we’re off Saturday and Sunday, work Monday, are off Tuesday and Wednesday, and return to work on Thursday.

      It’s the same total number of days off, but it’s way less useful - especially if travel is involved.

      but the UK has the fewest public holidays in Europe. In Germany we have 9-13 but don’t get a day off if a public holiday is on a weekend. And we have a minimum of 20/24 days of holiday on top

      Wait, do other countries not do this? So if a public holiday falls on a Saturday it doesn’t get pushed to Monday?

        Don’t do that in Norway either - just bad luck if the holidays happen to land on a weekend. On the other hand, we have five weeks of paid vacation, and holidays are not counted into those, I’m not sure how that’s done in other countries?

        Germany doesn’t do this, but the minimum, when all holidays fall on the worst possible days, is more than the number of holidays in the UK.

      This is true for all public holidays in the UK, there’s a (usually) fixed number of public holidays but the dates are flexible.

      They’re also included in the minimum 28 days paid time off too, meaning if you’re a full time worker and have to work on a bank holiday your employer is legally required to offer an extra day off somewhere else instead, either a fixed date or added to your holiday allowance. Conversely, the “extra” day off you get when a monarch keels over may be subtracted from your holiday allowance for the year. This is also why my employer is allowed to follow English bank holidays despite having next to no presence in England; the number is fixed but the dates are not.

    It is literally happening this year.

    24th is Tuesday. 1st of January is Wednesday and as a bonus Jan 6 is also a holiday in my country and that’s Monday.

    So from dec 22 to jan 6 i can be home by using just 6 days off

      The 25th is a Wednesday, not a Tuesday like he was wanting. Tuesday is nice because you get a four-day weekend without using any days off. (Though, usually you’d get the next off if it was a Monday or Sunday or whatever.) I think the best is Friday or Monday because then New Year’s gives you a three-day weekend too.

    systemd is the future, and the future has been here for over a decade and yet old Unix and BSD purists still cry about it

    I have one simple thing to say to the downvoters: I am not using a minicomputer from 1970, why should I be bound by the limits set then?

        I’ve felt like systemd has been a breeze compared to the hodgepodge of different stuff that preceded it. Now most distros have it mostly the same way, tools are well documented, things works together. It wasn’t always like that from what I remember

      You need a calendar and time handling anyways for logging purposes and to set timers correctly. It’s likely not that much extra work exposing that functionality.

        No, UNIX philosophy demands that every single one of those things is one or more separate things and that half of them are poorly or not at all maintained. Just like God intended.

    Usually such things have a simple explanation. systemd does a lot with time and date, for example scheduling tasks. It’s quite obvious that it has this capabilities, when you think about it.

        Too much

        But that has been a complaint for 10 years and it’s only gotten worse

        I wouldn’t mind systemd if it weren’t for the fact that it was to be a startup system that promised to make everything easier and faster to startup yet managing systemd is a drag at best, and of it did one thing it’s making my systems boot up like mud

      I thought the same, but didn’t we already have things like chron syntax for this? Systemd didn’t have to build its own library.

          Aight, didn’t know that. I cannot yet imagine any scheduled task that would require anything more advanced than cron (or a similar standalone syntax), but I’ll just trust you with that one.

      Just take the next step and make a text file you dump all these commands into and then forget about in a week. When you randomly stumble across it years from now you’ll be able to say “wow, I could have used this 10 months ago if I remembered it existed!”

      I feel you. It’s however gotten a lot better since I turned some of these commands into abbreviations. They’re aliases that expands in place, more or less. Fish has them natively, I personally use zsh-abbr.

          Yeah, it’s a good shell. I’ve found the lack of compatibility with some bash tools to be inconvenient enough that I just went back to zsh and found alternatives for the parts that I liked about it. Works well enough for me.
