Enable EBPF on WSL2
By default, EBPF programs will not run on WSL2 due to required kernel modules missing. The following example error is an
indication of this problem:
modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.19.84-microso
ft-standard/modules.dep.bin'
modprobe: FATAL: Module kheaders not found in directory /lib/modules/4.19.84-microsoft-standard
chdir(/lib/modules/4.19.84-microsoft-standard/build): No such file or directory
To fix this you need to rebuild the WSL2 kernel with the missing kernel modules. The below instructions are for Ubuntu 18.04 WSL2.
1. git clone https://github.com/microsoft/WSL2-Linux-Kernel.git

Zig in 30 minutes

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)

A complete compiler for a simple language (in less than 150 LoC)

This project is a tiny compiler for a very simple language consisting of boolean expression.

The language has two constants: 1 for true and 0 for false, and 4 logic gates: ! (not), & (and), | (or), and ^ (xor).

It can also use parentheses to manage priorities.

Here is its grammar in BNF format:

expr ::= "0" | "1"
