Dell Optiplex 3011 AIO Touchscreens

I have several (10+) Dell Optiplex 3011 AIO Touchscreen computers I got from an upgrade job a few years ago. I have found some great uses/projects utilizing these computers:

My Kid's School:
*Computer lab for highschool running Mint for web use and running Wine for some Rosetta Stone software
*Computer for teachers that they mainly use for access to Google Drive and Docs in their classroom.
*Computer for kid's library to run web-based library software to catalog books and check them in and out.

My Church:
*Computer in the sound booth that I operate that is connected to the sound board.
*Computer in my Sunday School Class that I use to connect to a TV to run presentstuon slides and videos.

My Home:
*Retro gaming machine.
*Ongoing project: Machine to run a family calendar, store recipes, watch YouTube videos, display family pics, etc.

I have also gifted a few of these to my family, for retro gaming and young kid learning games.

I have 10+ left and trying to come up with more ideas to use them for. I like the idea of Home Assistant, but I don't currently use it and don't have a ton of smart home devices, other than plugs, lights (bulbs), and Echo Dots, so not sure if there is much benefit there.

TLDR; Looking for project ideas to use on several Optiplex AIO Touchscreen computers.

I was tired of searching for the perfect window manager for X11, so I decided to write my own.

will there be new open source games?

I started using linux a year ago and there is much I don't get yet. I know that a long time ago there were these games like tux cart , super tux, and 0.A.D that were made for linux. but now with WINE being more advanced there are basically no reasons to build new of these open source games, the market niche is gone.

so my question is, now that most games work in linux, is there a reason to build these open source games?

by the way I think open source games are cool and I want to see more of them, they are so optimized for some reason.

In your opinion, what was the worst Linux distro that you've ever daily driven for at least a month?

(noscript pretty much says it all)

Curious to check out what y'all say... I'm only making this post because I'm bored. Maybe the distro could be something that broke too often after updates as one example.

It's easy to take image rendering in a terminal as granted, let alone video rendering. It's so cool when you think about it.

mbwol - Multi boot Wake on LAN

Hey guys,

So for a long time, I wanted to be able to remotely boot my PC. The problem is, I dual boot Arch and Windows, so I was stuck with only being able to boot one OS remotely.

My first solution was to set Arch as the default boot option. If I wanted to boot into Windows, I had to wait for Arch to start, run a command to change the default for the next boot, and then reboot. It worked, but it wasn't great. Even if it could be automated, the PC needed to boot into Arch before it could boot into Windows, which made the boot time longer.

And one day I stumbled upon this superuser post. I tried it and it worked flawlessly !

Basically, you set up a TFTP server on another machine that serves a text file. In this file, you set the default boot option to use. Then, you configure your GRUB to request this file and source it. After that, the only thing you need is to wake your PC and find a way to modify the config file served by the TFTP server.

So for a few months, I ran a TFTP server alongside my Home Assistant instance and made a noscript that would send a WoL packet to the PC and change the content of the file served by the TFTP server to set the right boot option. This worked great, but I felt it was still a bit too hacky.

So I developed a Go service that handles the WoL and TFTP, mbwol !

https://github.com/bducha/mbwol

This is intended to run on an always on device on you network. You send an HTTP request to it, and it will boot your PC with your OS of choice. It also supports multiple machines.

I've been running it for several months now and it has been working great, so I think now is time to share it !

I agree that this is a niche use case, but maybe some of you will find this useful.

Enjoy ! And feel free to report bugs or suggest improvements !

Should I switch from Windows 10 to Linux?

Hello, I think I want to switch from Windows 10 to Linux Mint. Later this month Microsoft wont support Windows 10 and my laptop has been slowing down. I dont have the money for a new PC to upgrade to Windows 11. I mostly just edit photo, video, draw, chat on discord and watch YouTube.

I am not sure if Mint is the right choice for me or if I should pick a different OS. I have 8 GB of ram and 1TB of hard-drive. I have used Ubuntu in the past but that was over 10 years ago, and I know things have changed.
