58 bytes of css to look great nearly everywhere

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 {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

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

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Installing ROS1 Noetic on Ubuntu 22.04

The process is pretty similar to the standard installation from source except for some fixes that you will have to make during the installation. I will keep the same header so you can keep a track on both guide at the same time (follow the official website for more explication, I will only write the steps to make).

1.1 - Installing bootstrap dependencies

Fuzzing CDT: Finding, reproducing, and reporting bugs

Introduction

This is a tutorial on how to write a fuzzer for a non-trivial real-world library, namely Artem Amirkhanov's CDT. It is a library for computing Constrained Delaunay Triangulations (CDTs, hence the name of the library). We will be working from the 9d99b32ae56b26cd2781678dc4405c98b8679a9f commit, since that is what I originally wrote the fuzzer for, and that way, we will be able to rediscover the same bugs I found back then.

If you want to follow along, clone the library using

$ git clone https://github.com/artem-ogre/CDT
$ cd CDT

C++ Build profiles for 2024 projects

C++ Build profiles for 2024 projects

Standard development profile

This profile achieves 50% - 80% release profile performance, while also provides a reasonable amount of safety checks and debugging support. This should also be the profile for your CI build.

Compilation flags

-Og -Wall -Wextra -D_FORTIFY_SOURCE=2 -fstack-protector-strong -g -D_GLIBCXX_ASSERTIONS
