Have you ever failed to reach a goal you set? well most likely you have. We are humans after all and failure is built in our existence. However, we are also different in the way that we deal with such failure, regardless of that difference, I believe most of us have what I call the mean voice in our head, or have had it. I have it, from time to time, it comes up to remind me of my failures, to tell me what I could have done better. If you have such a voice in your head, I think it is a good thing, to some extent. That mean voice could be inner moral or ethical guidance that helps you make positive and righteous decisions, it could also be the result of a toxic relationship you have with yourself. Whether that is a good thing or not is yours to decide. In this post I want to talk about how I feel about that mean voice, and how I have learned to bargain with it so that we can both live together in the same body without h

Hello reader, this is the first article of a series where I will be trying to recreate arithmetic operations in binary using C Lets' get into the good stuff.

What the heck am I doing exactly

Well, as I said, arithmetic operations, I will start with integers first, so the goal is to have functions for every operations (addition, division, substraction and multiplication) that would take in 2 integers and return the result of the corresponding operation. The catch is that we are not allowed to use the "built in" arithmetic operations in C, meaning this

Hello reader. I have been trying to replicate the dev container experience that I had when I was still using vscode (I use neovim now btw) but it wasn't quite that, I tried some neovim plugins but didn't really like it. But I'm happy to tell you that I finally got something, just for Golang apps, but we are getting there. Let's quickly see how I achieved this.

Required dependencies

You will need docker and docker compose installed on your system. I use Manjaro so for me installing these two was as easy as running

pamac install docker docker-compose

Once you have these two installed you will need a text editor, I will be using neovim. What I mean by the "dev container experience" is to be able to have my code on my host, but run and debug it inside a container so that way my computer doesn't have any dependencies and I can easily reproduce the dev environment on another PC without having a "it worked on that other machine" moment. As exemple we will build a simple Go app that returns "Hello world

Introduction

Hello reader. In this article you will learn how to implement Github oauth in your apps using Golang on the server. I will be using Sveltekit for the client app but don't worry about it because we only need it to test the backend logic. Let's dive in

How does Oauth work

First we need to understand how oauth work under the hood, for the matter I made a simple diagram

Purpose

A certus file is meant to contain "pseudo code" that describes an HTTP request, that code will be parsed by the certus cli and executed.

Comments

Every line starting with a '#' will be considered as a comment and ignored.

Sending a request

The first line in a certus file (if every comment is discarded) should be the line where the user defines the HTTP method and the targetted endpoint. An exemple

	package main

	import (
	"encoding/json"
	"fmt"
	"strconv"
	)

	func pigeonAgeToHumanYears(pigeonYears int) int {
	if pigeonYears <= 1 {
