I started delving into world and dungeon generation with different techniques.
The one I want to try is wave function collapse.

There are several videos and repos explaining and showcasing how it works and how it can be used to generate an infinite world.

One question I have and haven't seen any mention about is, how do I recreate/reload the map from any point other than the original starting one?

So, AFAIK the algorithm start from a few tiles/pixels in a starting position, or picking their position at random, and then can collapse the rest of the map with the set of rules given to the building blocks, but if these starting tiles/pixels are far away after a player saves, then I can only think about having to start from them again to reach the saved point to be able to show the same world which of course could mean a very long loading screen.

Maybe the save can include the current seed, but then it can advance differently when the player goes back, which means the algorithm would generate a different portion of the map.
How can I ensure the world would be regenerated as it was?

While writing this I'm thinking I could be generating the seed of a block of tiles/pixels based on the seed of neighboring blocks and the coordinates in the map, something like left: seed+X, right: seed-Y, where X and Y are calculated based on the coordinate of the block.
This way I can save the seed of the current block and easily recalculate the seed used to generate all the adjacent blocks.
What do you think about this approach?

I have an old android tablet (and several phones) that I want to use for small applications in my home automation.
For the most part just to show a web page to quickly click something to activate or read the status.

My issue is the OS installed is very old and of course there are no official updates.
Looking for custom roms they are also somewhat old because the age of the devices, and everyone says "don't use the rom of one device into another even if the models are very similar".

So, my question is, what are my options if I can't use a pre-built rom?
Could I keep the same OS and just restrict access to only my internal network?
Not sure if I'm being too paranoid about security risks using these devices to just connect to my services.

What's your recommendation for a selfhosted services to stream some private videos from S3 compatible service (vultr)?

I was thinking a private peertube instance could work, but it requires the S3 files to be public and allow all origins, so I don't like that idea.

The other one was to use rclone mount to have it as another block storage, but I don't know what are the cons of this, or if it's possible to use it with this kind of services.

This won't be for my camera videos (already have immich) nor for series/movies (jellyfin). It'll be for random videos from youtube, or twitch which I want to hoard.

(Also if you have a recommendation for cheap online storage for this it'll be appreciated, Vultr's is $0.006/GB)

I've been looking for an all mesh chair since I tend to run hot so every chair I use ends up making me sweat.

There's this one Naz President Full-Back Mesh but I can't find any reviews for it.

There are also these two in amazon Razzor Ergonomic Mesh Office Chair and FelixKing Ergonomic Desk Chair but I've been reading mixed reviews (as well as any other chair in amazon)

So, do you guys have any budget all mesh chair recommendation? Or maybe a chair which doesn't heat up so much or cools down quickly?

(I currently have a gaming chair... worst purchase I've ever made for my back)

I want to have something similar to a google's nest hub to display different type of information, like weather, bus times, my own services information, photo gallery, etc.

It's not a problem if I have to manually write plugins for custom integrations.
It'll be better if it's meant to be shown in a web browser.

I remember there were some related to a screen for a digital mirror, or a kiosk screen, but I can't find a good one to selfhost and extends to my needs.

The ones I've found are focused on showing stats of deployed services and quick links to them.

I'm trying to add the audio of a video to another one so I can have multiple tracks for my media service (Jellyfin).

The issue is the new track doesn't have any sound, it's just there with the proper metadata but it's just mute.
I tried playing it with Jellyfin and with VLC.
The original audio tracks play fine.

This is my command.

ffmpeg -i .\3.english.mkv -i .\3.french.mp4 -c copy -map 0 -map 1:a:0 -y .\3.mix.mkv

I also already tried adding -c:a:1 ac3 since this is the format of the audio in the mkv file.

The data of the original audio of the mkv is

Stream #0:1(eng): Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s
    Metadata:
      title           : English

      _STATISTICS_TAGS-eng: BPS DURATION NUMBER_OF_FRAMES NUMBER_OF_BYTES

The data of the file I'm trying to inject from the mp4 is

Stream #0:1[0x2](fre): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 189 kb/s (default)

      handler_name    : movie.track_2.aac
      vendor_id       : [0][0][0][0]

do you guys have any idea of what might be the issue?

I also tried extracting the audio to a file and the aac file works fine, it's just when adding it to the mkv which doesn't work.

I've seen a lot of people mentioning EQ bank to have the emergency save since it offers 2.5% interest.

Just recently knew about wealthsimple with 4% https://www.wealthsimple.com/en-ca/spend

So I'm wondering if you guys know any drawback on saving in wealthsimple instead of EQ.

Est-ce que c'est CEHI en français ? Désolé, j'ai encore besoin d'utilizer un traducteur.

La banque EQ semble être la meilleure avec 2,5 %.
Mais WS donne 4%
Alors, je me demande pourquoi il n'y a pas plus de gens qui recommandent WS et recommande toujours le QE.

Y a-t-il quelque chose que je ne vois pas dans le WS? Dans la section "X", on peut lire "Remarque : Wealthsimple n'est ni une banque ni un membre de la SADC", cela pourrait-il être la raison?

J'ai vu quelque part un 11,5 % mais je ne suis pas sûr

Contexte: Si je n'ai pas atteint le maximum de mon CELI, devrais-je y mettre mon argent pour les dépenses mensuelles?
Ou puis-je les conserver sur des comptes d'épargne normaux? Juste pour ne pas avoir à me soucier des droits de cotisation.

Is there any firefox extension to process SRT or WebVTT files to show subtitles in any page? Not just video streaming sites.

Context: I have some subtitle files for some podcasts, so the site is only playing audio. I'm using podverse.fm
It'll be great to have something similar to lyrics sections in some music players to follow along the audio while reading.

In an API I have there's a requirement to use an authentication method other than OAuth2 or any kind of token generation which requires making an extra HTTP call.

With this in mind there's this https://www.xml.com/pub/a/2003/12/17/dive.html
I've only stored passwords as hashes and used functions like password_verify to know the user sent the proper credentials without actually knowing the password stored in DB.
WSSE requires to encrypt with SHA1 the credentials being sent, which means the API needs to retrieve the password in plain text to recreate the digest and compare it to the one sent by the user.
So, how should I be storing this password if the code needs it to recreate the hash?
Should I have something like a master password and store them encrypted instead of hashed?

Most of the information I've found about WSSE is very very old, and some implementations have it marked as deprecated, do you know any other type of standard authentication where the user can generate the token instead of having to make an extra HTTP call?
