    2. What's the best way to connect four monitors to two computers?

      I will spare you the life story of how I came to want to do this and instead outline what I would like to accomplish:

      • One (Windows) desktop computer with a video card that has two HDMI and two DisplayPort ports.
      • One (Linux) laptop that has two USB-C Thunderbolt 3 ports.
      • Four monitors:
        • 1920x1080 60Hz
        • 2560x1080 75Hz
        • 3440x1440 100Hz
        • 5120x2160 60Hz

      What I would like to do is connect all four monitors into a KVM switch, and then from the KVM switch, connect all four monitors to both the desktop and the laptop. I would also like at least one USB port on the KVM that I could connect a USB hub to for switching my mouse, keyboard, graphics tablet, etc.

      From there, ideally I would be able to switch all four displays and all the peripherals between each device by pressing a single button on the KVM.

      However, there are three problems I have encountered with this idea:

      • KVM switches are expensive as fuck
      • Very few KVM switches support a two-computer, four-monitor [2x4] connection (it is almost always the other way around [4x2])
      • The few KVM switches I have found that do support such an arrangement only have DVI ports, no DisplayPort or HDMI

      So uh, if anyone knows of any KVM switches (or other solutions) for accomplishing this setup, I would really love to hear about it, no matter the cost.

      Thanks.


      In this setup, the laptop would be the daily machine, and the desktop would be a dedicated gaming/creativity rig. That gives me some room for alternative configurations:

      • Because the desktop wouldn't really need access to four monitors, I could get a KVM switch that only supports two monitors [2x2], and then just use something like Synergy to seamlessly move the mouse and other peripherals between computers. However, I have concerns with how well Synergy would work with a custom mechanical keyboard (running the QMK firmware) (Apparently there are no issues between QMK and Synergy)

      • Buy two [2x2] switches, which is probably cheaper than one [2x4], and switch all four displays between devices with two button presses instead of one. (And still probably run Synergy for when I want to split displays 2/2 between devices)

      • Just use a Thunderbolt dock, plug each monitor into the desktop and also into the dock (so two cables coming out of each monitor), and just manually switch the monitors between devices using their input controls. This is probably the simplest option, but switching four monitor inputs can be tedious. Though, I wouldn't actually need to switch all four of them, I could just switch one or two of them, and then use Synergy to take advantage of the others.

      • Run the desktop headless and stream its video output over the local network to the laptop/monitors. This might actually be the cheapest solution, but input latency would be variable with network conditions and could be a concern. I would also be dependent on specific services for streaming output. Parsec would be my go-to. I have used it before, including with friends over 1,000 miles away, and it works great. However, I'm not too keen on my computing setup being dependent on a single (proprietary) service.

    3. What's a good way to learn how to maintain my own computer hardware?

      I have two computers (a desktop and a laptop) that broke down just before my city entered a lockdown. Being able to assemble and fix my own computer hardware is something I have always wanted to do, and if I knew that I would probably not be using a borrowed Macbook Air right now.

      I have no immediate need to provide any maintenance services, nor do I require a primer in electronics or anything too advanced. Just enough to know how to assemble and disassemble a machine, identify and fix the most obvious issues without breaking anything.

      I tend to learn better from sequential and structure learning materials, preferably in text/images form. But videos are also welcomed. I know the names of the things and what they are, but I don't really know how to put things together in practice.

      Suggestions? :)

      While I've been teaching myself my first programming language (Python), I've been getting more into using the terminal as much as possible to build familiarity and get comfortable. This has opened my eyes to so many useful utilities and makes me curious as to what there is out there that I haven't heard of yet.


      My favorites so far:

      exa - A modern version of "ls"

      youtube-dl - Download videos from youtube.com or other video platforms with various options

      hledger - Plain text double-entry accounting software based on ledger written in Haskell

      thefuck - App that corrects a spelling mistake in the previous command by typing "fuck"

      spicetify-cli - Customizes the Spotify client with themes and extensions

      spotifyd - Lightweight Spotify daemon

      spotify-tui - Control Spotify in the terminal

      neofetch - Launch tool that can display ASCII art or pictures and general system information

      I'm on macOS but I'm almost certain all of these are cross-platform.


      What are your favorite or "must-have" CLI packages?

      Don't forget to format your code using the triple backticks or tildes:

      Here is my schema:

        article_id   INTEGER
      , warehouse_id INTEGER
      )

      How do I add a `UNIQUE` constraint?

      I am wanting to run a few Ethernet cables through my house to reach various rooms and electronics, and to be able to move my router to a more central location. In terms of cutting through walls and where to put the cables, I have figured that out, but I need some advice on what I will need in order to properly run the cables.

      I clearly need the cable itself, but I'm not sure what kind to get or what tools to get to install. I don't need anything fancy, just enough to get the job done.
