Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

how to add python-style decorator to my language

convert mouse cursor image to left-handed (horizontally flip) using python

Recently I find that Windows mouse cursor is not very friently for left-handed people. Because it point from right to left.

So I wonder if there is a way to change it to "left to right". I searched the internet but havnen't found one.

Further search give me a message that the "cur" file format is a derivation of the "ico" format: https://en.wikipedia.org/wiki/ICO_(file_format)

So I think if we can flip it programatically.

change back iso file's default open program in Windows 7

I change an iso file default open program to C:\Windows\explorer.exe , and I can't change it back. (Try this in virtual machine, not real computer.) How to change it? My OS is Windows 7.

Tried this, but after I change it, the .iso extension disappears from the list.

I tried the registry, change Windows.IsoFile entry's shell->open value, and rebooted, but it didn't work, too

You can use ldd to view dependencies, then copy the related dll: https://web.archive.org/web/20240620214721/https://janw.name/posts/3-msys2-dlls/

Here is an example makefile (please use the code in solution https://stackoverflow.com/a/60906375/12291425, or use this gist):

it can save a hassle; create a file named GNUmakefile or Makefile and paste the content, then run make dist:

targets := prog.exe my_library.dll my_plugin.dll
