Scraping issue: Hidden Data? Meh.

• 15/8/2023

Details

On 15/8/2023, I have task to scrap a website. With simplistic mind, I thought I can just used BeautifulSoup and requests to get the information. However, the website that I intend to scrap has shown no text at all from the output of the code. I thought the website was purposely created to hide the information. After asking some colleague and read on internet, this is due to the JS framework that been used by the webdeveloper which is Tailwind and Bootstrap.

Issue

I just want to decorate my Powershell on Windows with oh-my-posh. It worked well, but when I opened my WSL Ubuntu 20.06.4, suddenly it initialized with bash and not zsh. It also change the default user to root instead of ammar-user that I have created at the beginning of installing WSL.

After 4 hours troubleshooting, I found the solution as below.

Issue

Most of the tmux shortcut required ctrl + b, <some_alphabet> which become a headache as it is similar to JupyterLab left-toggle shortcut that is ctrl + b. Hence, I want to disable the JupyterLab shortcut, so I can use tmux happily.

Revert the full commit

Sometimes you may want to undo a whole commit with all changes. Instead of going through all the changes manually, you can simply tell git to revert a commit, which does not even have to be the last one. Reverting a commit means to create a new commit that undoes all changes that were made in the bad commit. Just like above, the bad commit remains there, but it no longer affects the the current master and any future commits on top of it.

git revert {commit_id}

About History Rewriting

Delete the last commit

Deleting the last commit is the easiest case. Let's say we have a remote origin with branch master that currently points to commit dd61ab32. We want to remove the top commit. Translated to git terminology, we want to force the master branch of the origin remote repository to the parent of dd61ab32:
