How to make a small tweak to free software

The target audience for this is people who are beginners at software engineering and using linux. A lot of the information here may be obvious or already known to you. The language involved is C but you do not need to know any C to read this tutorial. I used mg to write this blog post. I used vs code to edit the source code.

If you use a piece of free software and it's 99% perfect but there's just this one thing it does that annoys the hell out of you.. you can in theory just fix it! Here's a look at what doing that is like. Hopefully it inspires you, or you pick up a could tricks on the way!

Step 0: Have a problem

Some tips for Git to Save your Life 👍

Rest branch to spefic commit or last commit

Firstly you need select th commit desired or simply reset the HEAD in current branch, (can check if you are in current branch using git branch.

git reset HEAD^ --hard // Or git reset +[commit]^ --hard

After that we need to force push doing this way:

function deque_init(d) {d["+"] = d["-"] = 0}
function deque_is_empty(d) {return d["+"] == d["-"]}
function deque_push_back(d, val) {d[d["+"]++] = val}
function deque_push_front(d, val) {d[--d["-"]] = val}
function deque_back(d) {return d[d["+"] - 1]}
function deque_front(d) {return d[d["-"]]}
function deque_pop_back(d) {if(deque_is_empty(d)) {return NULL} else {i = --d["+"]; x = d[i]; delete d[i]; return x}} 
function deque_pop_front(d) {if(deque_is_empty(d)) {return NULL} else {i = d["-"]++; x = d[i]; delete d[i]; return x}} 
function deque_print(d){x="["; for (i=d["-"]; i<d["+"] - 1; i++) x = x d[i]", "; print x d[d["+"] - 1]"]; size: "d["+"] - d["-"] " [" d["-"] ", " d["+"] ")"}
