Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

1. CPU-bound
2. Blocking IO
3. Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.

Introduction
============

Industry statistics as a whole have failed to improve much since 1968, when software engineering and
scientific management were introduced as means for resolving the "software crisis". Unfortunately
abandoned projects, cost/time overruns, and bloated, buggy software still dominate the landscape.

In spite of the efforts to mitigate this situation --like XP, agile, software craftsmanship or DDD-- the
reality is that a usual software project stack involves an increasingly larger number of programming
languages, DSLs, frameworks, systems, tools, techniques and processes, so it is a fact that the

Some thoughts on building software

Lately I have been busy reading some new books on Domain Driven Design (DDD) and software architecture -- including a short yet eye-opening one in Python and a great one in F#. At the same time, it seems that more people in the Functional Programming world are looking at more formal approaches to modelling -- some examples here. This has brought some thought from the background of my brain about how we should model, organize, and architect software using the lessons we've learnt from functional programming.

Before moving on, let me be clear about this being just a dump of some thoughts, not always well-defined, definite

Fibers

Fibers are an abstraction over sequential computation, similar to threads but at a higher level. There are two ways to think about this model: by example, and abstractly from first principles. We'll start with the example.

(credit here is very much due to Fabio Labella, who's incredible Scala World talk describes these ideas far better than I can)

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)
