Browse and organize your physical media collection on this website. The standout feature is the display: a three-dimensional shelf. “Take down” (click on) a movie and examine the box from every angle. For free.

There are still important limitations, such as the lack of 3D acceleration and the inability to put the system to sleep, but it works. Because of...
LibreOffice 26.8, released on August 26th, became the software’s most popular update. LibreOffice is a free alternative to Microsoft Office that’s been around for nearly two decades. In one week, the installer was downloaded more than 1 million times — not counting updates via Linux distribution repositories....
I avoid giving stage time to weird people (in the bad sense) here at the Manual. I’m making an exception to link to a July post by DHH, the Danish co-founder of 37Signals (the company behind Basecamp), creator of Omarchy, and author of a blog full of wrong ideas about immigrants and non-white people. He became the...
A website full of services to be accessed by Kindle and other tablets with E-Ink screen. Just open the site to notice why. There are even games! (Some services are behind a paying subscription.)
