  • IT tech here, yes, yes it can.

    Network infrastructure is both increadibly smart while also being dumb in other ways.

    To do an ELI5 answer:

    Imagine you have a container of pearls that you need to sort, red, green and blue pearls all need to be dropped into a red, green or blue hole.

    The container is being refilled, but slow enough that it only gets a new pearl once you have sorted the previous.

    The holes are connected to pipes going to separate buckets.

    Everything is fine, but then some adds a new hole that is muticolored and tells you that all pearls should go there.

    You tell your friends that you have a faster way to deal with the perls and to send you their pearls.

    The new hole also has a pipe, but that is connected to the container that recieves pearls, so every time you drop a pearl into the new hole, it appears in the container again.

    So now you have a situation where you not only get your normal ammount of pearls, but everyone else’s pearls and you also get every pearl you send back again.

    You are smart and quickly realize that something is wrong and call for your teacher for help, networking gear don’t have that capabillity to understand that it is wrong, it just looks at each pearl and not the big picture.

    If we go back to the real world, we have developed tools to deal with this situation, we have protocols line spanning tree which can have switches speak with eachother and figure out if there is a physical loop before sending traffic through it.

    There are other tools as well, but they all need to be configured and to be honest, it is easily forgotten or made a low priority since it happens rarely.

    It is something that is often implemented after a big outage.


  • That depends on your usecase.

    I have setup servers where I mounted extra drives on /srv/nfs

    When/If I switch to Linux I will probably mount my secondary drives to folders like

    /home/stoy/videos

    /home/stoy/music

    /home/stoy/photos

    /home/stoy/documents

    /home/stoy/games

    The ~/games will probably be an LVM since it contains little critical data and may absolutely need to be expanded to span several drives, though I would also be able to reduce the size of it and remove a drive from the LVM if needed.

    I’d make a simple conky config to keep track of the drive space used

    I’d just keep using the default automount spot for automounting drives.






  • When I was growing up we had a SAAB 9000, it had heated seats and because we live in Sweden that is very nice during the winter.

    Unfortunately, the controls for both the heated seats was located directly infront of the steering wheel, and my mom would allways be annoyed when I wanted to use the heated seats when she drove as she didn’t want me messing with the controls.

    I constantly had to tell her that I was just turning on or off the seat heater.

    I never tried to do anything else, but she was allways annoyed when I did that in that car.

    This post makes me wonder if she had this done to her when driving.

    Anyway, later SAAB models moved the controls away from the steering wheel and it became less of a problem.

    In my SEAT Leon the seat heaters are set through a thouch screen which is terrible, but I atleast have the control for a heated steering wheel on the wheel.



  • As someone who has lived alone for eight years using only public transport in an area with excellent public transport, I can tell you that you are both right and wrong.

    You are right in that if there is just one bus line, then it would only serve a small subset of people in this photo.

    But if you only make one bus line then the public transport system is doomed to fail.

    A good public transport system will have multiple lines converging to the same interchange, and in the opposite direction it will have multiple lines departing the same interchange, following the same route and branching off when needed, this way you have added capacity and redundancy at the start of the line, and it gets reduced as the need is reduced.

    Then add lines that are circles in higher density areas, this means that no matter the direction all passengers can get on all departures, you csn also quickly add capacity by adding busses that goes in alternating directions.

    All of this means that travellers can define their own route along different bus, train, tram, metro and ferry lines.

    Public transport is not ment to be point to point, it builds a framework where people decide what parts the want to use.



  • The one thing that still remains unclear with regards to science and god is the big bang.

    The way I have heard it explained is that before the big bang there was nothing.

    Which to my mind becomes:

    First there was nothing, which exploded

    This does not make sense to me, how can nothing explode?

    So there are three categories of answer to this question:

    A. There was something before the big bang which exploded, though this offeres not explanation of how the thing that exploded came into existance, I have heard theories about how the universe is cyclical and how it will eventually collapse into a new big bang, but that doesn’t answer the queation about the first big bang.

    B. God exists and triggered the big bang, that means that the god entity exists outside of our universe.

    C. We are just a highly advanced simulator, the big bang was the the program starting our simulation.

    We never really had this issue, but I would try putting the folded towels in a cupboard with a door. As for furniture you could try and fit some hard plastic over the favourite scratching area so she won’t get a grip with her claws.

    We had our cat when we were doing a remodel (still going on at my parents, I still remember when the front porch was ripped out and the big job was starting back in 2000, but even before then the house was being remoddeled.

    She loved to scrach against wodden posts so much so that over the years she had scratched away about a third of the equivalent of a twobyfour post.

    We let her do that since the post would hold little weight, and it is relatively easy to swap if needed.

    When cats sharpen their claws on wood it keeps them at the right length.

    The only time we needed to clip our cat’s claws was when she was getting old and couldn’t sharpen them herself.

    We noticed it when she was getting more and more passive, and on a whim we looked ar her claws, they had grown into her pads on her paws, we started cliping them regularly, but only slightly, and she was soon feeling much better.

    This happened after and accident when she was out and we thought she got lost, but after a few days she was back in our garden, she was clearly in pain so we took her to the vet and one of her rear legs had been dislocated, it took weeks to get it to heal, and after that event she started having trouble with her claws.
