Let's talk a bit about what makes the Superlogical multiplexer different architecturally from traditional terminal multiplexers! There's a lot (a LOT) more coming, but wanted to share a little bit about the terminal-specific part compared to tmux and zellij.

[Mitchell Hashimoto @mitchellh]

I've started a new company: @superlogical! We're going to begin by building a terminal multiplexer. The entire vision is much larger, but the multiplexer is the foundation. Sign up for the newsletter to get beta access and devlogs (product updates only I promise).

@xghana_ I see the vision 🙈. I’m definitely trying it with the coconut next time. Seems really good and healthy!

@AnnRoselynnn If you are really serious about this, non-traditional paths are very much available. But it will take a lot. Good luck!

@_mrahenkorah I envy him. His Twi is very good.

Xavier Leroy (creator of OCaml) is an expert in compilers, formal verification of software and functional programming.

This interview should be an approachable resource if you're curious about formal verification of software since I was learning that on the fly during it.

In this episode:

• OCaml compared with Rust and JavaScript
• What is formal verification and how does it work
• How languages call each other across boundaries
• How to address "almost-correct" LLM code
• How type inference works in programming languages

@kwadwosheldon @ygaokenneth I love his mastery over Twi for such a young guy. The way he weaves the words is pure art.

[Jethro Djan @JethroDjan]

I want to like a tweet to tell the algorithm to give me more of that BUT it’s not something I endorse… So what do I do?

[Jethro Djan @JethroDjan]

@eduleadership Understood. I see what you mean. I think her view is ironically reductive. For starters, that isn’t all learning science gives us. She identified a problem and gave a solution which feels like it should work but probably can’t prove that it does [over something that is proven].

[Jethro Djan @JethroDjan]

@eduleadership I now get both points of view. I agree with you that some knowledge is foundational and should be treated as such. I also agree that those skills are better taught as you described. However, I identify very strongly with their idea. It’s a huge problem in my part of the world.

[Jethro Djan @JethroDjan]

@eduleadership It’s a little strange to me. I don’t see how knowing how to prompt an AI or use a search engine would be considered ‘learning how to learn’ (unless I don’t understand the idea well). Is it some application of behaviorist and connectivist theories? Will look into it.

We are rewriting Postgres. And in the process, turning Turso into the LLVM of databases: https://t.co/KeoNfbzgun

[Glauber Costa @glcst]

I am excited to announce that we are officially writing a new version of Postgres. In Rust - and creating the LLVM of databases in the process.

In the span of a year, we have rewritten SQLite. Keeping the compatibility, increasing its feature set. MVCC, Types, (Live) Materialized Views, among other things. In the process of doing that, we have realized: At the end of the day, what makes SQLite special is that it compiles SQL to a database-specific bytecode. So why can't we compile *Postgres* to the same bytecode?

Turns out we can. I ran an experiment called pgmicro as a way to prove this hypothesis, and it works very well. It is time to make this official, and put the weight of Turso behind it. We shall give the world a modern take on Postgres. Wire compatible, but built on a new architecture.

We have already heard of others wanting to extend this. MySQL? Redis? the sky is the limit. What can we do if we do for databases what LLVM did for compilers? To prove how powerful the SQLite bytecode is, we are actually running DOOM compiled to the unmodified SQLite instruction set. And because Turso runs natively in the browser, you can play the game in your browser. With the database executing it.

@Iamlyday1 These things frustrate me to no end. At the very least, this act is in poor taste. Why does everything need to be ‘content’? People should be judged according to their deeds but YOU KNOW they will lump us all in. So why make life difficult for all who will come after you?
