  • I’m a few months into using CachyOS on my zephyrus gaming laptop and it’s been a joy.

    I actually ran into my first issue yesterday and had to boot into the windows drive for the first time in what feels like forever - I needed a Windows only display editor program for Nextion screens.

    I tried the installer on bottles and playonlinux, But I couldn’t get the program to load. I will try again today so that if I have to load it up in the future I don’t have to switch back to Windows, but on the off chance anybody knows how to fix it I’m all ears.

    I didn’t intend to use it on the chest freezer - it was mostly for the modem, but since I had spare battery capacity and outlets I thought what the heck.

    The power load is practically nothing until it cycles, and even then it’s fairly efficient - my current runtime is estimated to be about 18 hours, more than enough to come up with an alternative if we lose power in a storm.

    While I appreciate the sentiment, most traditional VMs do not like to have their power killed (especially non-journaling file systems).

    Even crash consistent applications can be impacted if the underlying host fs is affected by power loss.

    I do think that backup are a valid suggestion here, provided that the backup is an interrupted by a power surge or loss.

    I agree that 99.999% uptime is a pipedream for most home labs, but I personally think a UPS is worth it, if only to give yourself the option to gracefully shut down systems in the event of a power outage.

    Eventually, I’ll get a working script that checks the battery backup for mains power loss and handle the graceful shutdown for me, but right now that extra 10-15 minutes of battery backup is enough for a manual effort.

    This is why I have about five of these bad boys: CyberPower CP1500PFCLCD.

    One is in my utility room for my cable modem and our chest freezer, three back up my homelab and wifi AP, and one is for my office.

    They’ve been bulletproof through storms, and when we’ve lost power, but not Internet I can’t keep on working.

    The big thing to look for is number of battery+surge outlets vs just surge outlets. Typically they top out at 1500VA - the more overhead for what you’re powering, the longer you can go without mains power.

    A screen/display is helpful for at-a-glance information like expected runtime, current output, etc.




  • I use KDE as my go-to desktop environment - it’s the only option for my Steam Deck (which is shockingly good when hooked up to an external monitor), and I chose it for my Ubuntu 22.04 LTS work laptop.

    Yes, it does look different from windows, but depending on what global theme you use, it’s shockingly similar:

    • click on the icon in the far lower left to access “Applications”
    • Time/calendar, sound, wifi in the far lower right
    • Single task bar along the bottom that shows currently opened apps and pinned apps

    I spent maybe 10 minutes with my 70 year old mother and she felt comfortable using it despite being a Windows user since 3.1 days.

    Users are more resilient than you’d think - provide documentation on what’s new and you may even be able to sell it as “The upgraded version” of your old platform.

    Hell, the fact that you’re on Linux already is great! Most of the significant issues I run into when converting people over to the OSS side is software availability (coincidentally the thing that made my Mom switch back to Windows).


  • So first, let me be clear - I don’t know if an alternative to that software you first brought up. But some of our earlier CTFs had a similar issue with isolation.

    We ended up spinning up new VLANs per contestant, each having a single Kali Linux VM with xrdp, along with each contestants target systems. Our router/fw blocked all access in/out of those VLANs, save for RDP/SSH traffic from our Apache Guacamole server on the DMZ.

    So contestants would hit our portal (Guacamole), then from there connect into their own dedicated Kali instance and environment.

    Later, we had to make additional fw exemptions for our scoreboard/docs, etc.
