Git Commit Freeze Due to GPG Lock Issues

If you encounter a problem where you cannot commit changes in Git – neither through the terminal nor via the GitHub Desktop application – the issue might be a freeze during the Git commit process. This is often caused by GPG lock issues. Below is a concise and step-by-step guide to resolve this problem.

Solution Steps

1. Check for GPG Lock Messages

Open your terminal and try to perform a GPG operation (like signing a test message). If you see repeated messages like gpg: waiting for lock (held by [process_id]) ..., it indicates a lock issue.

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.
