  • No one is genuinely mad. It’s just fun to mock them.

    The genocide being committed in Palestine is something that makes me mad.

    The fact that we are happy for our largest companies to outsource work to poorer countries makes me mad.

    The fact that corporations seemingly control the world and don’t pay their fair share makes me mad.

    Fun fact: it’s possible to be mad about those things while also thinking a button is stupidly placed. It’s perfectly fine to not care about this at all, but acting like that is just annoying as fuck. Please just abstain.

    Wiring a staircase switch is actually very easy, you pretty much just need two wires going from one switch to another and then a light.

    Your light switches also has to be three way switches but afaik most switches in my country are that, so you can pretty much use any switch.

    XNOR (Exclusive NOR) is the opposite of XOR (Exclusive OR)

    A way to remember XOR is “must have one or the other but not both” XNOR is the opposite so it’s “must have both or none” so both inputs must be 1 or 0.

    XNOR or XOR is very common in homes with staircases so that you can turn on and off the light in the staircase regardless of which floor you are on.

    If you google staircase switches, you will be told that they mostly use XOR but according to the wiring diagrams they use XNOR.







  • FYI with many routers, switches, and firewalls there are ways to automatically rollback changes in case the device is unreachable after applying them. Usually the command is called something like “Rollback”.

    You usually supply a time limit when you run the command and if you don’t confirm the changes before that time limit it will rollback. So if you run rollback 30 and then do something which breaks the network connection, the config will rollback in 30 seconds. If it does work, you simply cancel the rollback.


  • The reason that most companies don’t want you to do that is because they don’t want people running around installing their own OS and doing whatever they feel like on company devices.

    Letting people do that would be an IT and information security nightmare.

    It’s the same reason that no (sane) company would give local admin privileges to everyone.

    The reason why companies generally don’t have an official way to use Linux is because it’s hard to support two platforms simultaneously. Especially when you have, certificate and/or AD network authentication for wireless and wired like we do. You also need to consider how the two platforms should interact with each other. For example Linux devices should be able to connect to the AD domain with Kerberos and need to be able to access SMB shares and probably other systems.

    In short it’s more complicated than “just let me try”.


  • I am a Windows admin but two of my colleagues who are Linux admins use Linux machines that are running Ubuntu+a few internal tweaks to make it better fit us. The Linux platform is developed primarily by one of the developers at the company and some others (primarily developers) also use Linux. The vast majority of the company uses Windows.

    There are also a few hundred Macs.

    I have been considering getting our flavour of Linux installed on a VM or maybe even dual booting for testing.
