A Gemini client* is needed for the following links.
> I've spent the last couple of days working on an image format, based on QOI, called QOI-Remix or QOI-R. For those who aren't familiar, QOI is a lossless image format created by Dominic Szablewski; the spec fits on a page and it's enormously faster than PNG, while achieving reasonably good encoded file sizes. I thought this was a really good area to be exploring, and one relevant to my own interests and to permacomputing (under the larger umbrella of efficient software.) With that in mind, I did several changes to the image format, adding a little bit of compute overhead but frequently achieving substantial reductions in filesize - and remaining far faster than PNG.

> Josephus.— See here, there is a "connected" method to check whether a TCP socket is connected.
> Aloysius.— The peer could close the connection the very next second.
> Josephus.— But I want to know whether the socket is connected right now.
> Aloysius.— This is also not possible; the peer may have already closed the socket, and one cannot tell the difference between the ESTABLISHED and CLOSE-WAIT states.
> I was trying to rescue my new Manjaro installation. But, I had never tried chrooting into a BTRFS volume before.
> chroot lets you rebase the file system from a running system (like a live USB flash drive) to the file system of a stopped system (like a broken Linux installation on your hard drive). By changing the root (chroot), utilities run inside the chrooted environment act as if they were being run on the computer that you are troubleshooting. So, if my Manjaro installation is not working, I can use my installation disc, chroot into my system, and run updates, check the logs, or run other utilities. In this way, chroot combines the functioning of the live system with the file system of the broken installation.
> I’ll jot down some quick thoughts on Lemmy, a Reddit-like service for the Fediverse. When it first was announced a few years ago, I thought “yeah, right, it has a really long way to go” and instead of helping I just sorted it under “vaporware”. But now it’s becoming usable♥.
> My general principle is that private conversation between known entities (like friends & fam) is usually a good thing and something humanity is well adapted to (since that’s how offline has worked for millenia) while anonymous immutable persistent broadcast is danger zone and unlike anything previous generations have had to deal with. Even a skeevy bathroom wall can be cleaned up or painted over.
> Whenever I read a Gemlog entry that I think I might want to reply to, I bookmark it for later.
> Old School Stylish (OSS) is an interesting zine supplement of 28 pages (counting both covers) for Old School Essentials (OSE). OSS drops the class system and instead lets characters pick up “styles”, which are small collections of capabilities. As they adventure they can find and acquire (with suitable effort) more styles. Everything, from hit points to spells to thief capabilities to Armour Class, are part of styles. Characters can have multiple styles active, and can switch out styles for other ones they have learned. By default characters still have levels, but there is a option for dropping levels as well. As you might guess from the cover image this zine takes inspiration from martial arts and cultivation media. OSS offers a lot of ideas for how to acquire styles in play, from petitioning masters to learning a style by observing special circumstances. It provides several tables to help you come up with interesting ways for characters to learn styles. It also suggests that the players NOT use the book to select styles for their character, but leave it up to the DM to place styles to be found in the world, which I thought was interesting.
> I'm enjoying the simplicity of Debian v5 (Lenny) on the old desktop [0]. I realized shortly after the install that I didn't have to rely on the DVDs I had burned to install packages on this box, I could take advantage of the Debian archive mirror itself, which works with Lenny and this sources.list
> What a wonderful BBS this is. I was able to sort out an error on adding a certificate within minutes ! Great job, Skyjake
> The rise of community-oriented services on Gemini, especially Bubble, has helped introduce more people to the protocol than ever before. Recently I've seen several different newcomers looking for more information on how to set up a capsule and have a more independent presence on the platform. I'll share how I do that in this log.
> This is not meant to be a guide, but rather a non-technical overview of how my capsule is set up, and it's written for an audience that is not as tech-savvy. It goes more into concepts than the particulars of the technology behind them. My hope is that recent arrivals to Geminispace can find this document, see what goes into operating my capsule, and get a better sense of how easy it can be.
> As I spend more time in text-based tools on the command line, I've become quite appreciative of the elinks browser. I've been building various portable Raspberry Pi based computers over the last while and I've realised that web browsers like Chromium and Firefox are the bottlenecks in terms of performance, because they are so resource-hungry. Netsurf is a nice alternative, but works quite poorly if using a touch-screen input, for example scrolling is quite finicky.
Gemini links can be opened using Gemini software. It’s like the World Wide Web but a lot lighter.
