Song title fades in AfterEffects

I’ve been working on a video of our live performance in Winston Kingdom using Adobe AfterEffects. To show the title of a song at the start and end of the song, I used a script to automate the fading.

Why doesn't Windows have a package manager?

After I uninstalled Visual Studio 2005 Pro I got this very long message (I’ve included it at the bottom of this blog post) telling me to manuall uninstall twenty other programs, in the correct order.

Removing duplicate mails

To sync my mail between computers I use offlineimap on a secure filesystem. Today I mistakenly ran offlineimap before mounting the secure filesystem, which caused it to duplicate all emails. Not wanting to do any manual work to fix this, I wrote a small Python 3 program that repaired the damage.

The current state of Big Brother

Big Brother is watching you. More and more invasions of your rights are done in the quest for “digital rights management” and “protection of intellectual property”. Check out Farhad Manjoo’s post Why 2024 Will Be Like Nineteen Eighty-Four, as he describes it much better than I ever could.

More power from your mobile's battery

I’m the happy owner of a Motorola Razr V3. Its battery used to last quite long, but now that it’s getting older it’s drained very quickly. At some point, I could charge it at night, talk a few minutes during the day, and when I got home in the evening the battery would be empty.

Highlighting the current line & column in VIM
