Science based practices for a meaningful life

Using python to write to a sqlite database, storing json data.

Sish is a great ngrok alternative to expose any locally hosted app over the web. With Sish you create temporary secure tunnels to locally hosted applications and allow others to intereact with the app with a publicly accessible web address. Its great to quickly expose a development app server without needing to deploy it and setup reverse proxies or mess around with firewalls. Sish can also be used to expose any TCP connection - e.g MySQL DB.

How to Self Host Matrix, an open source project that publishes the Matrix open standard for secure, decentralised, real-time communication.

Good explanation and simple steps. Federation can be tested here: https://federationtester.matrix.org/

Super small operating system (for x86) - couple of megabyte disk and around 8MB RAM and you're off.
Contains games, a simple text editor, table editor, image viewer, and some more.

An amazing little diy arcade machine and the building process simulating your working day in an Amazon warehouse.

Truly decentralized move-streaming application. Somewhat akin to bittorrent streaming (though, afaik, using IPFS).

Could be very interesting in the future, example public domain movies keyL QmR9f898E2Y6H4rUqUQkB5g615wht1q4fxCPfZzxA4jXaR

Tag, modify, update, and organize your music through the commandline (or through a web interface).

Seems pretty evolved and already comes with a nice plugin eco-system (for album art, mpd connections, gain setting and more)

Website blurbs:

• No hidden control flow.
• No hidden memory allocations.
• No preprocessor, no macros.
• Call any function at compile-time.
• Manipulate types as values without runtime overhead.
• Comptime emulates the target architecture.
• The language gracefully guides your error handling logic.
• Configurable runtime checks help you strike a balance between performance and safety guarantees.
• Take advantage of vector types to express SIMD instructions portably.

A fresh approach to metaprogramming based on compile-time code execution and lazy evaluation.
Seems a metaprogramming-heavy language.

Cut with regex patterns, automatic space mashing, column reordering, and some other nice features. Written, of course, in rust.

You can break an activated chain mode in sxhkd by sending it SIGALRM.
Additionally, you can change the way of normally exiting a mode by the commandline argument -a.
Finally, you can set 'double-mode' keychains, e.g. alt + m : alt + m which will only listen for alt + m when already in the same mode and then invoke the respective command.

Taking all together, it becomes possible to create chained modes which can be exited by pressing the same combination of keys twice (or any other key combination) instead of the pre-set escape,
which often interferes with actual program operation for me.

This could provide the last building block for my mode-based desktop version built with sxhkd and polybar.

It's a table that sets up another table's behavior. Say you have a table fnark where it's paramount that "YO HEADS UP" is displayed every it gets a new entry. The way to do that would he to create a new table (let's call it behavior) and set its newindex method accordingly. And you also want fnark to say "YEAH MAN ALREADY THERE" when some existing entry is accessed: you set that up in behavior's index method. When you're done describing behavior, you tell Lua that behavior is what defines how fnark should behave: setmetatable(fnark, behavior). And now, whenever you add some new entry or reference an existing entry in fnark, you get the messages from above. That's metatables in a nutshell.

simple shell script to send a message to a matrix room. Can be used e.g. in cron jobs to replace notification, or additional notification, or to only notify on user being AFK, or simply to replace mail(1).
Many possibilities, seems very flexible in its use-case.

Tidbits on software design, writing, testing, and so on.

While probably not to be taken as a bible, very neat to go back to every once in a while.

Android (AOSP) for different architectures, e.g. PinePhone!

A calendar created in rofi, with task functionality

A unix-only de-duplicating backup system. It is managed for you, encrypted and so on but also strictly tied (afaik) to the tarsnap 'service' - that means you can't just use your own object storage or similar like with e.g. restic.

Scrapes google cal api to get next events (for statusbar display).
Can probably be adapted for CalDAV or other services with not too much effort.

Integrates with DBus interface and can display notifications accordingly.
Not a replacement to dunst, but can be used to feed different things (like dunst or polybar) with information.

Also provides examples for grabbing the information from the DBus API and displaying it e.g. in polybar.
