I recently upgraded from Ubuntu 20.04 LTS to 22.04 LTS, and a bunch of stuff broke. As with my last problem, it’s probably because I had used third-party repositories or .debs that pulled in different versions of dependencies, so that updating to new standard packages couldn’t figure out how to also update the dependencies. Anyway, I was tired of the standoff, and just went ahead and removed a critical package (python3.
If you upgraded from Ubuntu 20.04 LTS to 22.04 LTS, and you’re no longer able to ssh-add -K because you’re getting this error: $ ssh-add -K Enter PIN for authenticator: /usr/lib/openssh/ssh-sk-helper: error while loading shared libraries: libcbor.so.0.6: cannot open shared object file: No such file or directory then you might try this: $ ldd /usr/lib/openssh/ssh-sk-helper linux-vdso.so.1 (0x00007ffd985a9000) libcrypto.so.3 => /lib/x86_64-linux-gnu/libcrypto.so.3 (0x00007feca56be000) libfido2.so.1 => /usr/local/lib/libfido2.so.1 (0x00007feca567a000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007feca5452000) libcbor.so.0.6 => not found … which will lead to this:
I’m importing some posts from my old sowbug.org blog, which ended in 2011. Most posts were garbage, or from the good old days of the Oversharing Internet. Those will stay offline. But a few had some thought put into them, and they’re worth republishing. Notes from scanning the rejects: Almost all the links to external sites are dead. I spent a lot of time learning and redocumenting how to use Emacs.
One of my June 2022 ideas was to build a groovebox. I’ve made some progress on the software side, and I’d like to talk about some of the interesting parts of the work. First: I’m developing in Rust. Choosing Rust was actually a no-brainer; it’s the right choice for new projects intended to compile directly to native machine instructions. So far, it’s been a great experience. I can see why people become Rust zealots.
These instructions are for setting up a Stable Diffusion instance on Google Cloud. I created an n1-standard-4 instance with an nVidia Tesla T4 GPU, which has 16GB of VRAM. I chose the “c0-deeplearning-common-cu110-v20220806-debian-10” image and sized it to 80GB. If I had it to do over again, I’d make a separate disk for the models and the generated output, but it’s not a big deal. Here are the (cleaned up) commands I used.
Idea: an e-paper printer. You can print to it, same as any printer, but instead of producing paper, it displays the last page printed. That’s pretty much it. I’d hang it on the wall in the kitchen, and I’d print recipes to it. It has no buttons or input, so I wouldn’t get food on it. I think the virtual-printer interface is important. I don’t want to write an app or curl to it.
On May 18, I started a four-week potato-only diet. I thought it sounded interesting, and right now has been a good time in my life to try an slightly unusual eating regime. I didn’t really care about losing weight, but I am overweight, so I wouldn’t mind it if I did, either. It’s now the first day after the four-week mark. I lost 7.8 pounds, or 4.3% of my starting weight.
Various geek ideas, maybe startup ideas. Some are ones I’m thinking about, and some are ones I wish you would think about. Solve the Sybil Attack problem. An online game bans a player for being a jerk, but the person creates new “sockpuppet” accounts and keeps being a jerk. It’s a hard problem to solve because it pits decentralization, privacy, and scalability against each other. Most solutions I’ve seen favor scalability over decentralization and privacy.
I’d like to start long-form writing more often. My motivation is to become a clear thinker. I believe that clear writing requires clear thinking, and that practicing writing is the same as practicing thinking. I used to be a good writer and a reasonably clear thinker, but today I wouldn’t describe myself that way. What changed? One difference is that my day-to-day writing doesn’t require as much deep thought as it used to.
While throwing out old storage boxes this weekend, I discovered my old Power Macintosh 6100, packed up in 1997. To use eBay terminology, it was in vintage condition. It had the mouse, keyboard, VGA monitor adapter, power cord, and a few floppy disks. There was no excuse not to plug it in and see what happened. So that’s what I did. The chimes played and the smiling Mac appeared on the screen.
