General setup
I work from home, at an Ikea corner desk my SO bought for me when I moved in with her and that has survived four houses so far.
I sit on a SIHOO M57 office chair. I had to change the gas cylinder because my desk is a tad too high, so I need to raise the chair at maximum height.
For the same reason I need to use an Ikea footrest.
On the right of the desk sits my personal desktop. On the desk, on a vertical cradle, is my work laptop.
Both computers share trackball, keyboard and monitor. Yes, this means I don't (can't) use both at the same time.
I have an arm-mount for my monitor, which is an LG 25UM58, an ultra-wide 25" I bought used off of Amazon. It has two HDMI inputs, so I can connect both computers and use commands on the monitor to switch between them.
My trackball is a wireless Logitech Ergo M575S. I didn't want to go wireless, but the intersection of budget and trackball is not that big. At least it's not bluetooth...
My keyboard is a white Redragon K552. It's a tenkeyless mechanical keyboard. It was sold with blue (unnamed) switches. I swapped in (unnamed) brown switches.
The keyboard and the trackball's receiver are connected to a small USB switch with a button that changes the connection between my personal and work computer.
There's a small ethernet switch (four ports) below my desk that connects to a powerline networking adapter that connects to my router. It's too far away to connect it directly via ethernet and I can't run wires through the walls. So slow ethernet it is.
If I need to access stuff from both computers (or from my smartphone) when one is off I have a Nextcloud instance hosted on Hetzner.
Work setup
Hardware
I have a work-issued Lenovo Thinkpad P15V with an Intel i7 12500H and 16 GB of RAM. It's connected to a USB-C dock that allows me to have power, USB and HDMI connections on the same size, otherwise I wouldn't even use it, and it's tucked away on the far side of the desk anyway.
The lid is always closed as I don't have room on my desk to keep it open and use the laptop's monitor.
Software
Windows 11, unfortunately...
I don't need many dev tools since moving from software development to a Project/Service management role, but I still do some technical work now and then, so some dev tools are still there.
As a terminal I mainly use the Windows Terminal, either launching Power Shell for quick command-line interactions or starting Debian via WSL when I need something more UNIX-y.
I use DBeaver Community to access databases, PuTTy for ssh and a bunch of text editors (either gVim, Notepad, or Notepad++ depending on my current mood). For more organized notes I use Zettlr.
I use Microsoft Office for... office stuff: Word, Excel (especially Excel) and PowerPoint.
I browse the web (and our intranet, and customers' remote machines...) via Google Chrome. No, I don't like it. I'm especially baffled by the fact that Ctrl+Tab is broken and impossible to fix (I want to jump back and forth between tabs, not just traverse them in order).
I use Thunderbird to read email.
Internally we communicate with Google Chat and Google Meet.
Other than that there's a plethora of off-the-shelf software we use internally that I'd prefer not divulging.
Personal setup
This, of course, gets a bit more complicated.
Other than the desktop machine I mentioned early I have some laptops that I play with sometimes and a couple of VPSs. All of these (and my phone...), together, form my "klezlab network", connected via Tailscale.
I'll start with my desktop computer (deimos) as it's the main computer I use when I'm not working, then the laptop I'm playing with at the moment, then the VPSs
deimos
Hardware
deimos is a Dell Precision T1700 workstation my workplace decommissioned and sold to me. It sports an Intel Xeon E3-1241 v3 CPU clocked at 3.50GHz and 16GB of RAM. It has two 1TB hard drives that used to be in a RAID configuration but I needed the space so now they're two separate HDs. I also swapped out the default nVidia Quadro K420 card because it's not supported anymore in Debian and now use an AMD FirePro W2100.
It is connected to the above-mentioned powerline adaptor, so the internet connection is not blazingly fast but it's more than sufficient for what I need.
Software
I've settled on Debian stable for years, so I'm always running the latest stable. I've also settled on Xfce as a desktop environment.
My choice of web browser lately has been Waterfox mainly because I rage-quit Firefox after the AI fiasco (I mean, not because of this specifically, but because it was the last in a long string of Mozilla blunders in the last decade) and I don't want to feed the Chrome/Chromium monoculture (also, see my comment on alt-tabbing being broken).
I use Thunderbird to read email.
I use the default Xfce Terminal.
I write prose and code on (g)Vim, with as little plugins as possible.
I backup stuff with borg on rsync.net.
aite
Hardware
aite is an old IBM Thinkpad X40 from 2004. I bought it for peanuts at an expo (and they even threw a charger in!) along with an additional GB of RAM, for a grand total of 1.5GB of RAM. It sports an Intel Pentium M CPU, an i686 (yes, 32-bit architecture) clocked at 1.2 GHz. It has a 40 GB hard disk. The screen is 12.1" XGA (1024x768).
The operating system doesn't seem to like the internal Intel wireless card, so I bought a USB no-name external card which I stuck behind the monitor with some adhesive velcro.
Software
It runs current OpenBSD.
dwm as a DE.
st as a terminal.
VPSs
I currently use two VPSs. I won't tell their names (at least for the second one, the first one is rather obvious...) because they're exposed to the internet.
One hosts this very blog using lighttpd as a web server.
The other one hosts some webapps for personal use, in particular a personal wiki (Dokuwiki), a RSS reader (FreshRSS), accounting software (Firefly-III), CalDAV and CardDAV hosting (Radicale).
It also hosts my git remote (with only a couple of projects shown publicly with gitweb) and a couple of utility webapps and sites I made for me or my family.
Both run on Debian Stable.
