↳ In-reply-to » got jenny setup and threads works completly fine but now I want to figure out how to get auto publishing working

@prologic@twtxt.net I never tried out any of the other clients except jenny with mutt. The best thing about yarn vs something like Mastodon is that its more promoted of the specification of twtxt files instead of server part. Twtxt can be hosted on some free static site host or some git server even so its really low resouces. Just a basic text file. As far as I know yarn is mostly just a web ui around twtxt and an extnetion to the specification to add some more usability and modern things. Anyone can join decentrilized network by having a twtxt file somewhere. If you want to support the specification of twtxt then that is really something most projects don’t do and they promote the server software mostly.

meet lol, my new website generator!

meet lol, my new website generator!

2022-08-08

I’ve been pretty busy lately, so I haven’t had a lot of time to explore
computers, which is what I love doing. In the last few months, I’ve been trying
to fight back against busyness by writing a new website generator after everyone
goes to bed. I can’t recommend doing this, because it gets exhausting after a
while, but it gives me my kicks and makes me happy.

My old website generator, [wg](https://git.m455.casa/w … ⌘ Read more

Hi, I am playing with making an event sourcing database. Its super alpha but I thought I would share since others are talking about databases and such.

It’s super basic. Using tidwall/wal as the disk backing. The first use case I am playing with is an implementation of msgbus. I can post events to it and read them back in reverse order.

I plan to expand it to handle other event sourcing type things like aggregates and projections.

Find it here: sour-is/ev

↳ In-reply-to » @eaplmx That reminds me, I should start doing some exercises, too. Years ago, I wrote a web application to track those and two other mates used it as well. This way we motivated us to do our daily pushups and situps. I even extended it to upload GPX trajectories from our bike rides and hikes to show the route on an OSM map. Finally, you could enter your weights and get a nice graph with all the ups and downs. I should revibe this project. And maybe even rewrite it.

@prologic@twtxt.net Haha, of course, no worries! :-) Yup, I thought to try Go for this web application this time. REST API and web UI would be both needed in my opinion. I have at least two mates who would need a UI instead of a programmer-friendly interface. :-D

It’s far from complete, but I started writing something down: https://git.isobeef.org/lyse/kraftwerk2
