I am working on my project swarmy, making data analysis of Starcraft 2 replays easily available for gamers/casters, all in rust, using nom to parse replay binaries and map data, exporting to apache arrow snapshots to analyze with polars, managing the data flow via tauri, exposing the aggregations/controls via leptos, using rerun to navigate replay timeline, bevy to deep dive through the maps and provide "geo" stats, this weekend started playing with bevy skein to manage assets/materials via blender.

I made something like this around 10 years ago to show wireless frequency coverage, luckily the country I was living in is small enough and close to the equator, I didn't support the curvature of the earth so I can't start to imagine how difficult it must have been to visualize it in the browser https://sourceforge.net/projects/waire/ in my case the earth was kinda flat lol, it was fun parsing the map data available back then and playing with SVGs, back then the rendering engine from Opera browser was unmatched

Wow this is super cool! Will you use something to draw this on a map? If so what? Is it the same data format available in Europe and North America? What is something you suspected was going to be trivial and turned out to be extremely difficult?

Awesome, maybe some negative effect over it, how often does it refresh?

Can you think of a way to use your live cloud data as the background shader for https://github.com/sebosp/chartacritty ? I was also hoping to draw the iss progression through the earth, but sometimes people use terminals to actually read and may become confusing... For the rewind functionality you could look into rerun.io, not sure it's compatible with your current libraries but may be fun

What's the equivalent to foreman/quickstart but for embedded devices, ie you got a bunch of devices, different architectures, different sensors to different pins, different versions of firmware, some of them off, how do you keep track of them?

Would this fit your medium to long term? It's a weekend work to automate: json logs go to Kafka, logstash consumer to store batches in hive partitioned data in s3 with gzip compression, Athena tables over these s3 prefixes and prestodb language used to query/cast/aggregate the data

This reminds me of MIT's open courseware, 601 SC, unit 1 with state machines, going all the way to build Fibonacci with them without recursion, tbh the moment the teacher translated the state machine to bounds to electrical circuit I felt it was a leap and I couldn't quite understand their relationship, maybe I missed a requirement course. I tried to express that course in Rust as one of my first projects learning the language here https://github.com/sebosp/rustexercises/blob/develop/ocw601s... and I think a similar iteration in the direction of this project would be to build the dependencies as drag-and-drop boxes over the browser (maybe egui) and connect the state machines by clicks, maybe download the generated code as either bash or compilable rust code, you know, for kids.

I'm old and I sympathize with your last sentence, I _imagine_ certain reinforced paths through repeated experience are myelin covered so much as to be almost static. But if I think of generations growing up, their brains aren't reinforced/seasoned enough to spot these "Wait... What?" moments in online content that is almost sensical but not quite. In a world with ever increasing AI hallucinated content, when children absorb fake content and build strong paths in their brains, at some point the words/meaning could be so distorted that you cannot understand anymore the person in front of you? I think of the political landscape where we have similar problems, social media algorithms curate content to keep you entertained within subjects A and B, and you have a community with shared values and you are seasoned and share its language domain. How would the landscape look like when the net can be bombarded by content that appears to be true, valid and useful but it really is not, for young generations? Also if somebody can paint the right myoline picture in my head (not plausible text generation but science) I would really appreciate it.

This is so worrying for me, the amount of digital garbage that can now be generated that is not obviously garbage, that one must read and discern first nonsensical bad text generation and second if factual, is truth becoming a needle in the hay stack? How can this be cleaned?

Is there an approximation/ratio in which the amount of digital garbage/hallucinations online generated by AI is so big that it cannot be used to train AI itself? Like are AI companies running against the clock because, say, in 5 years the internet will be flooded by false information to such an extent that it would render the internet as an invalid training ground. In a way requiring a snapshot of the internet pre-AI, because this is click bait problem times infinity it feels like

I wonder if AI generated web pages block AI agents from indexing their content, like, one engine indexing the other's content in a loop until the amount of digital garbage is so gigantic that is the end of the information era, or how are we ever stopping this? What is our failsafe?

The bad: I was an alcoholic and smoked from age 12 to age 30. The community builds a level of arrogance that they have access to special knowledge because they are in a specific stage in the evolutionary "destiny". Breaking bonds with other family/friends is almost needed because you don't hear their points anymore, just like scientology or other closed sects, not sure their proper name. You think you have a guardian angel too that your destiny is to survive and become enlightened and you shouldn't have fear, I had a couple of near death experiences because of this false sense of security, plus the constant wine drinking... The good: they pack a lot of trigonometry and algebra but then they teach you "sacred geometry"... They also teach basic quantum mechanics basics, but then teach you that the observer effect is controlled by our minds, or that you can transform a carrot into gold... So somethings are useful... I'm still recovering from these cults, it's crazy how much our minds can change, therapy takes a while to take and forgetting/re-learning also takes its time, as it should...

Even seated you would make these psssshhht sounds of pushing air out, you would end up sweating from a meditation session because your muscles would also be contracted as you focus on the hand position in your chest... In your mind you have to visualize words backwards and breath them out letter by letter... I still laugh at the "so be it" that has to be said with absolute certainty for your wishes to come true

Laugh all you want, when I was like 12 years old my family was into this weird techno-pseudoscience-cult of "Ramtha's school of enlightenment" and they have the biggest trance/shamanistic playlists, we had these long ceremonies of hours of dancing while listening to music like this and drinking red wine and smoking tobacco on pipes. I guess if it wasn't for the alcohol I would have remembered all these amazing songs but well... I think that sect is still alive and I wish they had a playlist somewhere outside their website coz I can't stand the website much due to the religious content bringing back drunk memories. If you know of such a playlist please share

I would love to learn about this... Specially in the era of demucs, maybe some python automation to ableton live tracks that we can modify through the day slightly? I have playlist with dozens of 1+ hour videos on YouTube of psytrance and I find them so enjoyable, full of bass and good for focusing (granted there's the obligatory 1 minute muttering in the song of Terrence McKenna but OK, if psilocybin helped them create these amazing songs then so be it )

New comment by sebosp in "ZeroMQ – Relicense from LGPL3 and exceptions to MPL 2.0"

sebosp — Mon, 09 Oct 2023 21:12:55 +0000

How does ZMQ compare to recent message passing libraries? Does it have a place in rust's tokio ecosystem? Are there projects that implement the HA transaction store to disk protocol "out of the box" ? Forgot the name... Binary star something? I always think of working with ZMQ as I really enjoyed it, but I can't see it as easy no deploy as Kafka with so much ACL tooling, easy Auth and debugging, dashboards, metrics... Maybe one more question... What are recent projects that use ZMQ behind the scene that you find a good place to learn more message passing techniques and their tradeoffs?
