Last Resort in Git: Reflog to the Rescue!

I use git regularly, but I am not an expert. Sometimes I want to do something very simple, and I end up executing a chain of command leading me to a point where nothing make sense anymore in my history. I don't know how this is possible, but it happened a couple of times to me.

One day was quite bad, and I thought I had lost all my work, until a colleague told me about git reflog. It an awesome command. Since I know it exists, it really eased the fear I had of loosing all my work. To make it simple, it's like a history of your branch's HEAD. So if you have done a reset --hard, for example, the previous version of your work should still be there!

If you type git reflog, you'll get a history with some SHA reference. Then you can use those references as you would with a more "normal" flow (like reset, diff, etc.).

 This is the git referenec about reflog.

Also, I found this help page about git, which is worth reading for sure. It's a "make your own adventure"kind of webpage, guiding you through your git journey.

How to generate a self-signed certificate with Openssl (using git windows bash)

I recently needed to generate a self-signed certificate to test a website locally. I wasn't familiar with the process, and I wanted to share here what I learned. First, we need a private key. A private key is a long series of characters that must be kept secret. In my context, it will be used to encrypt messages before the client and the server, in a way secure enough to prevent anybody to spy on them. Once the private key is created, we need to generate another file that will be the "signature" of our certificate. Among other data, this file will contains some information specific to the server's context: country, organization's name, email address of the organization's technical contact, etc. Once this signature is established, there are two paths: - Path A: If we want our server to be publicly accessible, every browser in the world must able to trust the certificate. In order for that to happen, we need to send our signature file to one of the official SSL ...

How to Compile a GTK4 program on Windows (using MSYS)

  I wanted to create a GUI program using C and GTK. I am using a windows operating system, so I had followed the instructions from the GTK Windows installation page . However, when trying to compile my program using: gcc main.c -o main.exe `pkg-config --cflags --libs gtk4` I had the following errors: gcc.exe: error: pkg-config: No such file or directory gcc.exe: error: gtk4`: No such file or directory gcc.exe: error: unrecognized command-line option '--cflags' gcc.exe: error: unrecognized command-line option '--libs' I noticed that the command  pkg-config --cflags --libs gtk4 was actually returning a list of required includes. It seemed that the gcc command simply was not able to recognize them. To solve the problem, I then created a Makefile, in which a variable called GTK_4_INCLUDES contains the list of includes.  The compilation command becomes:   gcc main.c -o main.exe $(GTK_4_INCLUDES) To compile the program in the console, I just had to type mingw32-make , a...

Fixing x-invalid-end-tag lint error on Vuejs

  My situation is: Coding with vue in a Vue file. Using the Vetur plugin in VS code It then generates an error of type x-invalid-end-tag in a quite random fashion. To solve it, I have found one simple trick in this github issue: // .eslintrc.js module.exports = {  //... rules:  { 'vue/no-parsing-error': [2, { 'x-invalid-end-tag': false }]  }  }
