Hey everyone! For some reason I decided to build a CPU from scratch starting about five years ago. My BOM is NPN BJT transistors, 100/1k/10k ohm resistors, 47uF ceramic capacitors, and LEDs used as visual indicators/in-circuit debugging aids. The technology is basically RTL and compatible with TTL voltage levels. The components are designed and laid out by me using KiCad. The boards are manufactured by OSHPark. The ISA is my own design. I'm partially through board design and layout.
Documentation, schematics, stdlib/BIOS source code, simulator, assembler/disassembler, and other utilities are all available here: https://github.com/dragonMinded/minidragon
For those who have followed me awhile, especially when I was on my previous instance, this is not news. It might even be why you followed me. But, I wanted something to pin to my profile. Also, I wanted somewhere to post that I am going to be using the #MiniDragon hashtag in CPU-related posts from now on if that's all you're interested in seeing.
@alda I've been watching Stargate SG-1 recently and felt very much the same about that.
I've lost count of how often I went "did your supposedly elite unit not go through basic military training or what?!" during an episode.
I've never even been in the military and even I know that a bunch of the shit they do is something you get explicitly taught not to do!
(It does seem to get a bit better as the seasons progress...)
health, immune system
If the progress so far is any indication, I'm going to conclude that my immune system is definitely weakened, but it was aggressive enough to begin with that I'm still left with a serviceable amount of disease resistance.
It's taking longer than it usually would to recover from this, but it seems about similar to the more insistent flus and how other people experience them. Though I don't yet know what the long-term consequences will be.
(This is all pretty much as expected; that I have an aggressive immune system was something I already knew, given my history of "being sick for a few hours and that's it" whenever I caught a flu or whatever)
health
Feels like I'm coughing out my lungs, but it seems like my fever has fucked off, at least.
Also a pounding headache, but that's probably "just" the tension in my shoulder/neck muscles leaving my body, as that usually results in headaches.
I was recently asked to provide a quick opinion on a paper for a journal. One of the criteria the journal weighed heavily was whether or not the paper was "of broad interest to mathematicians in diverse fields".
Mathematics is so specialized at this point, that in my opinion, essentially zero papers meet this criterion. In recent years, I might list Yitang Zhang's work, or the discovery of aperiodic monotiles. Perhaps I am overly specialized myself, but I look at the titles of recent papers in non-field-specific mathematics journals, and I find no papers that look relevant to my work. Which is fine! Publishing papers that are big advances in their respective fields is great. But I would almost certainly be lying if I claimed that (in my opinion) any given modern paper in mathematics is of broad interest.
Is this a me problem?

food mentio
@Riedler (This is also the same place that - still! - sells expired food on the cheap and just *tells* you that it is expired, which honestly I can appreciate)
@Riedler I've never had the experience myself (don't have a car), but I was quite fascinated by it reading up on it - and ended up looking at their past location lists, because the various articles about it neglected to mention the "industrial park" bit 🙃
re: food mention, hilariously weird (2)
@eloy Yep :p
food mention, hilariously weird (2)
This was the same frozen food discounter whose previous business model was "here's a bunch of dates, times and addresses at industrial parks where our truck will be, show up with cash and you will get one (1) box of miscellanous frozen food", to give you an idea of the kind of outfit that this was
food mention, hilariously weird
Reminded of that time I ordered a bunch of food from a frozen food discounter, they turned up for the delivery, went "the one thing was out of stock, would you like this other thing instead that I have a few boxes of in the van?"
And then when I said that I wasn't sure if I would like the flavour, they opened a box of it *then and there* so that I could sample it and decide, and took it back into their van and just refunded the money instead when I indicated that I didn't like it
(Als het de bedoeling was dat de fabrikant niet te herleiden zou zijn uit de restpartij die ik gekocht heb, dan zijn ze daar niet echt in geslaagd...)

@bumblebeedc Right, so then the process would look something like this:
1. Download a "live" ISO for something like Ubuntu or Pop! OS (you can try both and see which one you prefer most).
2. Either burn it to a DVD, or flash it to a USB drive of some sort (microSD card in a reader works too), using Balena Etcher: https://etcher.balena.io/ -- note that this will erase whatever is currently on the card/thumbdrive.
2b. (Alternatively, you can use Ventoy to put multiple ISOs on one drive: https://www.ventoy.net/en/index.html)
3. Reboot PC, go to the boot menu using your computer's specific key combination (usually briefly displayed on startup). If it doesn't say, boot into the BIOS/setup instead, there is usually also a menu there.
4. Then select the card/thumbdrive as the device you want to boot from. It will now boot into a 'live' installation of the distro you picked - it won't install anything on your system or delete any data on it, it runs *entirely* off the thumbdrive/card.
5. If you're happy with how the chosen distro works, you can usually install it directly from the booted system, often there's a shortcut on the desktop. This *will* make changes to your system.
6. In the installation, carefully check what it says about the changes it will make to your disk or filesystem; by default it *should* resize your Windows partition, and install the Linux distro next to it, giving you a choice each time you boot.
If it suggests *replacing* it instead, make sure it's okay for your Windows installation (and all the personal files on there!) to be deleted.
If it suggests resizing, then it *should* not break your Windows installation, but it's always good to have a backup regardless because the process is not perfect.
7. Once the installation is complete, you should now be able to reboot your system and boot into the new Linux installation :)
I haven't used distros like Ubuntu for a long time, so I probably won't have much advice for Ubuntu-specific things; but there is a lot of online help to be found for Ubuntu, and Pop! OS specifically tries to be easy to use, which is why I suggested those specific options.
Installing software is going to differ a bit between distros; usually there's going to be something named "Install packages" or "Software center" somewhere, and that's the main way to do it.
Is that helpful? I can provide more guidance if you get stuck on something, of course, but this should be enough to at least get a working installation and tinker around with it.
If you don't want to install it yet, you can also just keep using the booted 'live system' off the thumbdrive/card indefinitely, and stop after step 4; it won't save any changes or files you make, but everything like "installing software" should work fine, it just disappears after you shut down. So should be good for trying things out.

Strong views about abolishing oppression, hierarchy, agency, and self-governance - but I also trust people by default and give them room to grow, unless they give me reason not to. That all also applies to technology and how it's built.
