Efficient matrix multiplication

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {

  padding: 2rem;
  margin: auto;

Automatic ISS Docking in Javascript
// Auto-pilot for docking with the International Space Station
//
// The program uses Artificial Intelligence and Decision Trees (i.e. basic kinematics and a bunch of if statements)
// to perform docking with the ISS from any starting position.

// To use it:
// - open the SpaceX simulation website: https://iss-sim.spacex.com/
// - open the Developer's console and paste the contents of this file

Use Sourcetrail with ROS

Use Sourcetrail with ROS

1. Build your workspace with the required cmake flag

Building your workspace with -DCMAKE_EXPORT_COMPILE_COMMANDS=ON which will create a file compile_commands.json in your build/<pkg> directory containing all compiler calls.

colcon build --cmake-args -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

2. Add the project to sourcetrail

Wireguard on Linux 5.0.0-23-generic (for Free5GC)

So you're using free5gc (hence stuck on linux 5.0.0-23-generic) and want to use wireguard VPN.

tl;dr you need wireguard-linux-compat tag v1.0.20200520

git clone https://git.zx2c4.com/wireguard-linux-compat
cd wireguard-linux-compat
git checkout v1.0.20200520
cd ..
make -C wireguard-linux-compat/src -j$(nproc)
make -C wireguard-linux-compat/src -j$(nproc) install

Installing ROS1 Noetic on Ubuntu 22.04

I made a repository where you can create issues if you have any problem during manual installation of ROS1. It will hopefully help people to find their problem more quickly. If you have any problem with the steps below, please:

  1. Check if someone else had the same problem below this gist,
  2. Create an issue on this repository otherwise.
