  • They’re quite versatile computers for general purposes, but their i/o performance is dreadful. Mine all max out at about ten megabytes per second. That will not do, for server purposes.

    Fortunately, there’s businesses all over that are chucking out all their old mini PCs since they won’t run Win11. I got an extremely decent one for £20 and it’s my new home server. Absolutely storms it, while just sipping at electricity.


  • Yep. Arch on my personal multi-use laptop, Arch on my work Java-development laptop, Arch on my gaming PC, Arch on my home Forgejo / DNS / NAS server. Just easier to not have to remember how to do things in different ways, plus my home server can efficiently act as a repo cache.

    Did have ALARM installed on the home server back when I used a raspberry pi, and while that’s an amazing project, a pi is just a bit underpowered for some uses. Got a mini PC extremely cheap since it wouldn’t support Win11, but it runs Linux like a champ.


  • Awesome page, thanks. Have bookmarked.

    Harfbuzz though? That’s going to take some replacing. Hopefully someone will fork an earlier version. The thing that it does (accurate multi-script font shaping) is difficult to do; requires a lot of rule-of-thumb knowledge that’s unlikely to be possessed by a single person, needs a lot of collaboration.


  • If you’ve any suggestion on how to implement that, then it’s a million-dollar idea.

    The “I’m a human” test that only takes a few seconds and then lets you do what you like for an hour was always vulnerable to ‘auth farms’. Pay some poor bastards in the third world a pittance to pass the test a thousand times an hour, let the bots run wild. And the bots have gained the ability to pass the tests themselves, at least by boiling the oceans in some datacentre while the VC money holds out.

    Finding the people running the bots, fitting them with some very heavy boots and then seeing if they can swim in the deep ocean is probably needlessly cruel, but I’d be up for tarring and feathering a few. Once the videos got out, the rest might think harder about their life choices…

    Mine was my local Forgejo server, NAS server, DHCP -> DNS server for ad blocking on devices connected to the network, torrent server, syncthing server for mobile phone backup, and Arch Linux proxy, since I’ve a couple of machines that basically pull the same updates as each other.

    I’ve retired it in favour of a mini PC, so it’s back to being a RetroPie server, have loads of old games available in the spare room for when we have a party, amuses children of all ages.

    They’re quite capable machines. If they weren’t so I/O limited, they’d be amazing. They tend to max out at 10 megabyte/second on SD card or over USB / ethernet. If you don’t need a faster disk than that, they’re likely to be ideal in the role.








  • The corona is indeed super hot, but also quite tenuous in comparison to the rest of the sun. The photosphere is only about 5500 °C. If our solar panels were made of diamond they would have melted at 3500, but it’s not impossible to imagine a solar panel that could be positioned ‘quite’ close to the sun’s surface - would just need to be made from some quite fancy materials.


  • That number didn’t really seem enough to me. However, the solar luminosity is about 3.8×10^26 watts and the surface area about 6.1×10^18 m2, ie. 62.3 MW / m2. 8760 hours in a year times 62300 kW equals 545 million kW/h, at twenty percent efficiency times twenty cents each is $21.8 M/a.

    The sun might seem to be really, really hot; but in fact, it is just quite hot and really, really big.
