The dark mode, also called night mode, is a special color schema which uses light-colored text on dark backgrounds. The opposite of dark mode is the light mode which is or was the de facto default schema. The dark mode not only has effects on the human body but also on the power consumption of newer devices.

Have you ever deployed a feature which interrupted your application because the schema change on the MySQL database has locked the table? Then I have good news for you! There are some tools like the Percona Toolkit which can apply the operation without a downtime.

On the 20th March 2015, there was a partial sun eclipse. I wanted to make a timelapse. I put my camera on a tripod, placed the sun in the lower left corner of the display and started the timelapse mode which made a photo every 5 seconds. After 20 muinutes, I realized that the sun will soon move out of the picture.
