  Espial is an engine for automated organization and discovery of personal knowledge (by Uzay-G)

I'm researching how we can use technology to improve the way we learn and find new ideas.

I'm currently exploring how AI/Natural Language Processing can automatically organize personal knowledge and notes by tagging and linking ideas together [0], removing the friction of organization to help you find new connections and ideas.

If you're interested in this domain, I'd love to talk to you!

  🎵 Tutorial showing how to use audio analysers to update a WebGL scene 🔊

I've just released a WebGL experiment that uses music to animate particles. It's meant to be exciting to both watch and create (the music - not composed by me - is pretty epic).

And it's done with a visual node-based editor I'm working g on. Here is a tutorial of it in action.

  The practical relational programing language for data-oriented applications

  

I'm working in a spiritual successor for the dBase/Foxpro family of languages (https://tablam.org).

I have published my initial attempt, and now trying to get serious on the parsing (the internals are far more powerful than the porcelain let it see). This is to be able to show errors like in https://docs.rs/ariadne/0.1.3/ariadne/ (yesterday finally the first!) and get some type inference/checking.

Plus, lossless parsing so it could work well with a editor.

This have proven to be harder than expected!

----

After it, I wish to work on the UI and embed a DB (sqlite) but also wish to build my own rdbms, how hard it could be? :)

  Apache Pinot - A realtime distributed OLAP datastore

  

For analytics sometimes SQL is not the best query language. In many practical scenarios analytic queries require looking at most rows of a dataset, but only at a few columns.

This is what OLAP-like engines are built for.

When you have these types of queries, the relational model ends up degenerating in a star schema with queries issuing a join for each data column on the first projection, and then a pass on that projection for aggregation, typically working on a time range that's relatively recent.

For these, native columnar stores are usually a better option. Things like Apache Pinot https://pinot.apache.org/ might be a better fit.

If you add a real-time requirement, it gets even more challenging, going into the realm of custom built query engines, such as those that back products as those built by Medallia or other customer experience companies.

It's a really interesting niche.
