  • I’ve done some very dodgy things with VGA cables in an effort to route the cables through narrow bulkheads. For normal computer-to-monitor-lengths this is probably fine.

    I haven’t noticed much signal degradation below 4m-ish.

    At 12m, you better solder properly and wrap some extra shielding around your splice.

  • Norway: Pretty chill, at least in my corner of the country; squeezed in between three mountains and a fjord.

    My biggest concern these days is that I was supposed to go down to Saudi Arabia for some work stuff, but that’s been put on hold due to… stuff you may have heard of…

    The news cycle is kind of repetitive because of a douchebag who is related to royalty is on trial. Nobody cares, lock him up if he’s found guilty, that’s all. I guess it’s a sign that there’s not much newsworthy happening.

    On a more personal level, I’m waiting for my meshtastic radios to arrive so I can put up some routers on nearby summits and see if I can reach the next tiny town over. No reason other than toying around with it, really.

    With geology like this, I have no idea how they manage to supply gigabit internet to my house. But I guess once you’re used to digging tunnels for basic infrastructure, running a fiber isn’t that big of a deal. My basement homelab enjoys the results either way.

    Day-to-day life isn’t exciting. But it’s safe and secure; the good kind of boring.







  • Not that proud, as it’s a fairly trivial IT thing with niche elements. “Anyone” could do it, but there are so many different elements, all of which are trivial separately, that there aren’t a whole lot of people in the world who can do what I do because of the odd combinations.

    So while my work is (mysterious and) important for the particular industry I’m in,I’m sure any IT geek with networking and linux experience could do it after a few years of training.

    As for importance, kinda. The higher-ups consider it important enough to grant me every demand I stated when they tried to poach me from my previous employer. I was looking for an excuse to turn them down, but they agreed to everything. For example, my contract stipulates that any flight over four hours warrants business class.

    My biggest point of actual pride is the fact that I got to where I am despite growing up on a dairy farm and never finishing hischool.




  • I’d say that a good starting point would be the smallest setup that would serve a useful purpose. This is usually some sort of network storage, and it sounds this might be a good starting point for you as well. And then you can add on and refine your setup however you see fit, provided your hardware is up to it.

    Speaking of hardware, while it’s certainly possible to go all out with a rack-mounted purpose built 19" 4U server full of disks, the truth is that “any” machine will do. Servers generally don’t require much (depending on use case, of course), and you can get away with a 2nd hand regular desktop machine. The only caveat here is that for your (percieved) use cases, you might want the ability to add a bunch of disks, so for now, just go for a simple setup with as many disk as you see fit, and then you can expand with a JBOD cabinet later.

    Tying this storage together depends on your tastes, but it generally comes down to to schools of thought, both of which are valid:

    • Hardware RAID. I think I’m one of the few fans of this, as it does offer some advantages over software RAID. I suspect that the ones who are against hardware RAID and call it unreliable have not been using proper RAID controllers. Proper RAID controllers with write cache are expensive, though.
    • Software RAID. As above, except it’s done via software instead (duh), hence the name. There are many ways to approach this, but personally I like ZFS - Set up multiple disks as a storage pool, and add more drives as needed. This works really well with JBOD cabinets. The downside to ZFS is that it can be quite hungry when it comes to RAM. Either way, keep in mind that RAID, software or hardware, is not a backup.

    Now that we’ve got storage addressed, let’s look at specific services. The most basic use case is something like an NFS/SMB share that you can mount remotely. This allows you to archive a lot of the stuff you don’t need live. Just keep in mind, an archive is not a backup!

    And just to be clear: An archive is mainly a manner of offloading chunks of data you don’t need accessible 100% of the time. For example older/completed projects, etc. An archive is well suited for storing on a large NAS, as you’ll still have access to it if needed, but it’s not something you need to spend disk space on on your daily driver. But an archive is not a backup, I cannot state this enough!

    So, backups… well, this depends on how valuable your data is. A rule of thumb in a perfect world involves three copies: One online, one offline, and one offsite. This should keep your data safe in any reasonable contingency scenarious. Which of these you implement, and how, is entirely up to you. It all comes down to a cost/benefit equation. Sometimes keeping the rule of thumb active is simply not viable, if you have data in the petabytes. Ask me how I know.

    But, to circle back on your immediate need, it sounds like you can start with something simple. Your storage requirement is pretty small, and adding some sort of hosting on top of that is pretty trivial. So I’d say that, as a starting point, any PC will do - just add a couple of harddrives to make sure you have enough for the forseeable future.
