    I've started to look into getting a 3D printer mainly for printing minis and terrain for TTRPGs. For the aficionado and print quality the best printer type seem to be resin based printers, but I don't think I'd be able to deal with the toxic fumes in a safe manner. As such I've settled on looking at filament based printers and I don't really need super high fidelity prints.

    I need one that works well with Linux and preferably OSS. I am willing to pay for closed source software (or OSS) if it runs on well on Linux. So if you know of any software that is easy to get started with I'd be happy to hear about it. If you know of any models or makes that I should avoid I'd also appreciate a heads up!

    Any other advice for someone just getting started with 3D printing?

    I used to program in Scala quite a bit (10 years back). The language had a bunch of warts when I was working with it. Full XML support embedded in the language. Implicits. Slog to build stuff with sbt. Standard lib was messy IIRC. I enjoyed it, but wouldn't recommend it to build a system with in a team.

    I remember liking the Lift web framework, it did use a bunch of "magic" language features. But it was a nice setup. Unfortunately I don't think it got enough traction... Play kind of took the air out.

    This is kind of neat! As an aside, at work we use slack and they have a feature to summarize meetings which we tested out. Unfortunately it is set up to work only on English so our meeting in swedish.

    XXX makes several unclear statements about "multibo", "Cape", "South Africa", and other locations/entities.

    XXX makes references to "the boy", "the dog", and other unspecified entities, but the meaning is unclear.

    We found it hilarious. Feels like Slack at least could have detected that this probably isn't English and just given up on summarizing!

    My main worry here is if GDScript is good enough to handle "intensive" algorithms. If not, I can always use C#, or C++ if I really have to, and adapt the problematic algorithms.

    Another is what would be the best database manager for this, but I'll cross that bridge when I get there.

    With regards to performance I'd wager your choice of data structures and algorithms will be what has a noticable impact on performance (e.g if you are looking up entities in a list vs looking them up by id in a dictionary). If you notice performance issues and you're sure it is due to using GDscript, then you can always drop down to a more performant language with less overhead. But, to me that seems like something to postpone as long as possible.

    As for using a database; do you really need one? If all game entities are loaded into memory operating on them directly can often be more efficient than db queries (especially if you have a small amount of "rows" eg 10s of thousands).

    I think it is common for companies to prioritize increasing revenue rather than decreasing costs. Decreasing costs can be deferred to when it becomes necessary; bringing in new revenue is likelier to have a larger impact on the business. As a real example I had a system running in AWS using SQL Server at a client. That database was the main cost of the entire tech stack. We did a PoC for migrating it to PostgreSQL which would have reduced the cost by 90% IIRC. It would have taken, realistically, a few weeks to prep, test and deploy and then monitor for hiccups. That cost reduction would have payed for itself in maybe a quarter. Still haven't been done. Priority is given to things that is perceived to increase potential revenue, i.e. features.

    I posted about it in ~games.tabletop, but I figured I'd elaborate here a bit. I wanted to try building a non-trivial piece of software using only prompting and for a while I've had an idea for a VTT. So I started out using Google Code Assist as a plugin to VS Code. I've managed to prompt coax it into something that works ok. Part of the clunkiness in the current version is due to not having a server component at all (besides the hosting of the static webpage and scripts). It relies on WebRTC to connect the players. The GM sends out invites (url with base64 encoded "offer") and the player must then copy and send the response (an base64 encoded "answer") back to the GM. That must all happen out of band, e.g. via separat chat or email. Once the connection to the GM is established that person acts as a signaling server for all the players so all peers can establish connections without the whole invite dance. I might rework this whole thing at some point, but I want to build some other features first.

    It is a bit of a hassle to test it out on my own properly since I ideally need a whole group of players to connect and test it out. But before I do that I want to make sure that it can handle reestablishing a connection e.g. on page reload and I'm a bit unsure if that is possible to do without a new invite.

    I am both impressed with the Llama ability to produce code and a bit dismayed that for some simple operations can take quite a while to figure out what it should do. Smaller refactorings and shifting the code around is much faster if I do myself, larger requests can sometimes cause the agent to end up in a never ending loop. Sometimes the context isn't big enough to handle the output causing it to crash. So you often have to instruct it to first make a step by step plan, then start on step 1... then ask it to do step 2 and so on. All that said I don't think a non-web developer would be able to prompt it to do this properly. I have a big advantage from understanding the underlying technologies and can steer the LLM/agent to a solutions I want.

    The whole code base is up on GitHub under an AGPLv3 license. If you want to try it out the application is available at:
    https://vtt.lindqvist.dev

    Edit: Just wanted to mention my favourite feature so far; the distance based volume when players claim tokens. The audio for peers is adjusted based on the distance the other peers token is from my token. It is there to encourage more roleplay (and perhaps shouting hehe).

    I think we should aim to minimize gambling in general. There are people who enjoy gambling occasionally and completely banning gambling will not make it go away (just drive it underground). The trick I think is to make the industry pay for the externalities it produces. I.e. calculate the rough cost of gambling addiction on a societal basis then charge that to the companies engaged in gambling. Use the money to finance gambling prevention and addiction therapy. Re-evaluate the cost occasionally. Hopefully this would lead to the industry finding some sweetspot where they balance the harm and financial gains. A lot of tweaks could be done to ensure different types of gambling are charged appropriately.

    Yeah, that was one of the reasons to do this. I have it in the back of my head to add walls that hinder sound, but we'll see if I get around to it. I want to improve the UI a lot before that. Of note is that anyone can move any token. I didn't want to limit it to just the GM and controlling player since I often find I want to illustrate something eg. "Can I push that character here if I stand there?"

    Being on vacation I wanted to try out coding solely using an LLM. I've mostly been disappointed with the results when using it on existing projects, but I've seen that it is quite capable when building frontends. So I figured I'd try it out from a blank slate and see if I could prompt it to create a custom VTT for me.

    There were a few of requirements that I wanted to solve.

    1. Voice communication between participants.
    2. Basic board controls for the GM (adding tokens, a map etc).
    3. Should be deployable as a static site. No backend required.

    To solve this I figured I'd use webrtc. It enables connecting multiple clients to each other sending data and audio streams. The tricky part is that in order to set up the communication channel a signaling server is commonly required. That is the peers need to exchange some data in order to agree on how they should communicate. Since I didn't want to set up a signaling server the initial connection need to be mediated in another way. Currently this is handled by the GM creating invites and sending them to the participants (outside the web app, e.g. in a text message). The participants then need to send back an answer containing their encoded signaling information to the GM. Once that is completed the GM acts as a signaling server for all the other peer connections. In short the initial setup is a bit clunky and currently if the GM looses the connection it's a bit of a hassel to set it up again.

    I also added a feature that I think can promote role-playing. A player (or the GM) can claim a token. If two participants claim some token then to each other the volume of their audio streams will depend on the distance between those tokens. So if two claimed tokens are far apart they will hear basically nothing, but if they move closer the volume will increase.

    The UI/UX is very basic and will needs a clean up and some more features (dice rolling probably being the main thing missing). Some features are a bit hidden, eg:

    • the GM can change the size of individual tokens by double clicking on them.
    • right clicking a token allows people to claim that token.
    • the GM can add, scale and move a background images for a layer and toggle visibility of layers
    • the GM can shift click to remove tokens

    That said, I think there is enough there to make it possible to run an session.

    The source code is on GitHub and all of it is licensed under AGPLv3 so feel free to poke around. Since 99% of the code is promoted it is a little bit messy with some shared state. The whole thing is deployed as a GitHub page so you could clone the repo and deploy it elsewhere on your own server by just hosting the files.

    Of note is that in some cases the communication between peers need a STUN server. Currently this uses Googles one. So if that is a concern you'd need to find an alternative. It also doesn't have a TURN server configured so some clients might not be able to connect.

    If you just want to test it for yourself you can open a second private window in eg Firefox and invite yourself in order to see what it looks like for players. Try it out and let me know what you think! I'm happy to answer any questions.

    A couple of years ago I bought a surface pro and installed Linux in it with this special kernel:

    https://github.com/linux-surface/linux-surface

    This enables multi touch and a few other features. In the end I didn't end up using it as much as I expected cause I got a contract working for a bank and they provided all the hardware with some MDM software installed so now the device is mostly collecting dust. I just ran it with a vanilla Gnome DE and configured it a bit to make the UI a bit bigger (mainly just theough scaling IIRC).

    I wanted to train a NN to recognize my handwriting (but I never really go around to it) so I could use a stylus as the main input device like a keyboard with some gestures for some input sequences... Would be a fun project to pick up again at some point.

    Just as a fun fyi, in case you are unaware, homomorphic encryption allows for processing of encrypted data. I've never gotten around to doing anything with it, but I do find the concept super fascinating! In the case for the OP it is way beyond what is needed (simple approach of just hardening the server, encrypting the data at rest and using https should be good enough), but if I had all the time in the world I'd be keen to use it.

    I started donating blod again after a hiatus due to traveling abroad and then not remembering to scheduling it in. Sadly last time I was scheduled my iron levels were below the cutoff for being allowed to donate so I've had to postpone it a few months. Anyway, the really nice thing that they've set up here in Sweden is that you get a short text message when they actually use your blood! They didn't do this before, so I was pleasantly surprised when I got the message that they'd used my blood to help someone. That really made my day and I felt super proud for being a donor. I think this one addition to the donation process probably increases multiple donations more than anything.
