My OCaml exploration continues (the Real World Ocaml book is great!).

This week I added a replication layer to my key-value store. I think I'm starting to get the hang of it...

I also wrote a blog post about how I did it:

I wrote a short post with my notes about Eio, the OCaml 5 async IO library. Still many more things to try, but one step at a time!

This weekend I continued my OCaml experiments from last week. I added a Write Ahead Log to my toy Key Value store!

I wrote about it here:

Really enjoying OCaml so far!

Thanks! I’m using Emacs and Merlin, with the utop extension. It works when I run it by itself, but if I try “dune utop” it has some formatting error in the buffer…

During the last couple of weeks I've been playing with OCaml. I went back to my super basic key value store, and re-implemented it in OCaml.

I also wrote a bit about it here!

Designing Data-Intensive Applications, 2nd Edition Data is at the center of many challenges in system design today. Difficult issues such as scalability, consistency, reliability, efficiency, and maintainability need to be resolved. In addition, there...

Chapters 1–7 of the second edition of Designing Data-Intensive Applications are now available in early release (sorry, O'Reilly subscribers only at this point). Among other changes, you may notice that we now talk about “sharding” rather than “partitioning” www.oreilly.com/library/view...

I spent some time this afternoon learning how to call Zig from Common Lisp! I figured it may come in handy for my Redis clone at some point.

I got it working, but I found some weirdness, may be due to memory alignment, that I can’t explain yet.

I just started a new experiment, implementing a basic Redis clone in Common Lisp.

This is what I have so far:

Yes, I staying with Emacs for now, but I will keep an eye on it.

Three questions about Apple, encryption, and the U.K. Two weeks ago, the Washington Post reported that the U.K. government had issued a secret order to Apple demanding that the company include a “backdoor” into the company’s end-to-e…

I just tried Lem, the Common Lisp editor. It looks really promising! Is anybody using it as a main editor already?

As a second book, On Lisp is nice, and also available for free. It’s a deep dive on macros!

Have you played with Erlang? It has a different view on how to do error handling and concurrency.

On a similar vein there is “Build your own Redis”, I may actually try that one in Common Lisp!

I was missing writing software from scratch, so I’ve decided to save some time every week to reinvent some wheels, and force myself to blog about it!

To make it more interesting, I decided to use #common-lisp!

This is it so far:

I guess most people don’t take it home with them.
