Science based practices for a meaningful life

Shows a step-by-step procedure to upgrad PG behind a docker container.
Can be adapted for other version differences.

Needed a few tweaks on my side, especially if using a different username/password/role, discussed here.

Successfully migrated my nextcloud database on-premises using the following:

 export USNAME=<my-db-username>
 export PAWOO=<my-db-password>
mkdir -p pg16
docker run --rm -v $(pwd)/nextcloud_db/_data:/var/lib/postgresql/12/data -v $(pwd)/pg16:/var/lib/postgresql/16/data -e POSTGRES_USER=$USNAME -e POSTGRES_PASSWORD=$PAWOO -e PGUSER=$USNAME -e POSTGRES_INITDB_ARGS="-U $USNAME" tianon/postgres-upgrade:12-to-16

Which then leaves me to move the resulting pg16 dir either into the other volume, overwriting existing data or just switching it around.

Take care that the pg16 directory that you are writing into exists but is completely empty otherwise there will be errors.

A long list of 'smells' (i.e. often viewed as indicating bad practice) when programming. Take it as ibspiration and indication, not gospel.

Can provide per-user service managers with the required functionality.

Somewhat hard to explain but essentially you can take any service manager (currently, especially dinit and runit are given as examples but s66 and similar should work) and have it work in a user-space mode, not just system wide.
Fundamentally does so by seeking to be an alternative to logind.

Can also take care of XDG_RUNTIME_DIR management which is nice for example for voidlinux.

A much more advanced cron daemon which seeks to have many opions and rivals systemd timers in some of its functionality.

Can have uptime-based and periodical timers in addition to the usual date and time based ones. Can take machine downtime into account. Can provide randomness and jitter. Can be invoked from scripts and only run when e.g. an internet connection exists. And more.

A crond which seeks to stay light and easy while having some (anachron-like) niceties.

restic-compatible backup implementation which is (apparently - have not used it yet) a little more memory efficient during various operations (backing up and pruning iirc?). That could be a big help for bigger backup jobs.

It also includes some other niceties over plain restic (atm) like no lockfile being present, and able to transfer the backup to a wider variety of storages.

Overall seems a little less stable (or 'boring') than plain restic, but a little more willing to add features - while staying compatible with the rust repository protocol which is awesome.

Many reasons of why not to put your extension cords in a long chain with many plugs and a big load.

A lot of information for Tassimo T-Disk barcodes. Gives indication for further hacking attempts. Some additional links (also found on the page itself):

• OneOfSix made some of the original decoding attemps and explains some of his journey.
• wiki.mbirth.de contains a lot of good knowledge, updated through 2016 and with further reading and might be the closest to actual decoding of the codes.
• spreadsheet of barcode experiments super interesting experiments with barcodes, someone went through and changed one bit at a time and observed the results

All of this information together with further tests could actually make Tassimo capsule machines somewhat useful again, perhaps even for non-capsule uses. (I am imagining 'refillable' capsules in which you just pour your ground coffee, add the correct lid and use it like a normal coffee machine; or even just using it as a tiny water kettle)

A super slim sudo alternative. Only a few lines of code, but configuration needs to be done in the actual header file (suckless-like).

Brings integration with rdoedit (similar to sudoedit) for file editing.

Another sudo replacement utility, focusing on being an alternative to su specifically (hence, 'simple su').

Can't say much about it since I haven't used it a lot but always happy with simple, open alternatives.

Simpler alternative to sudo - allegedly more secure through less attack surface (though also fewer eyes on it than sudo).

Originally comes from OpenBSD but made to run on a variety of unixy systems.

Replicates actual cities in minecraft. Pretty mind-blowing but also logical if you think about it - neat!

A universal app for OpenStreetMap.

In my view one of the best web offerings for openstreetmap (now that qwant maps is no more). Has super functional search, POI showing, integrated with weather services and a type of streetview.

Seems still in its initial phase and is a little rought around the edges here and there but could be one of the premium offerings for OSM on the web.

Pretty nice new-ish openstreetmap web implementation, can be used to create local meeting points and more.

Explicitly excludes showing details about many commercial chains (e.g. most supermarkets) because it is focused on local- an fair- places, those whose focus is to make a living not profit.

This of course hugely impacts its daily driver usefulness but also provides a nice alternative view on places.

A fully-featured OpenStreetMap-based map where markers and lines can be added with live collaboration.

Its search only supports specific 'points' (i.e. nodes) for now, but it has a nice POI function where you can filter by poi category and it shows you all the points around that may interest you for the current map tiles.

A curated list of blogs by (rough) topic.

Could ime be improved by adding a single tag or two to each entry to categorize a little further than just 'technology' for most of them.

Runs a lightweight Nextcloud-like Notes Server. Made for the Quillnote/Quillpad App - https://qosp.org/ OR https://github.com/quillpad/quillpad.

Emulates Nextcloud notes as a server and runs an SQLite DB which you can connect to from other users as well - neat both as a lightweight alternative and a proof of concept.
