Huy Le

Welcome to my blog!

Here, you’ll find posts on lessons I’ve learned, the things I find interesting, and what I am working on. Although I am not much of a writer, (really, it takes me a very long time to write together a post), it is an attempt to track my thoughts and share learnings through the years.

Although my interest is wide, you will most likely find contents regarding **software** and **hardware development** on this blog.

Feel free to scan around! If there is anything that may interest you, or if you have any questions, please feel free to reach out to me!

Wanna know more about me? Find out a little more here.

Feb 2, 2023 Patching Release branches with Git
Given two branches master and personal. You made some changes in your personal branch, and because the changes are very personal, you cannot create an Merge Request and push it to the public master branch. So you need to create a patch file that you can apply to master whenever it gets updated. Create a brand new branch git diff master personal > ../master-personal-patchfile git checkout patched master # checkout new branch from master git apply .
