Stellarium is a free open-source desktop app for Linux, Windows, and MacOS. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.

GNU Emacs editor released new 29.3 as an emergency bug-fix release this Sunday.

The new release intended to fix several security vulnerabilities described below:

  • Arbitrary Lisp code is no longer evaluated as part of turning on Org mode. This is for security reasons, to avoid evaluating malicious Lisp code.
  • New buffer-local variable ‘untrusted-content’. When this is non-nil, Lisp programs should treat buffer contents with extra caution.
  • Gnus now treats inline MIME contents as untrusted. To get back previous insecure behavior, ‘untrusted-content’ should be reset to nil in the buffer.
  • LaTeX preview is now by default disabled for email attachments. To get back previous insecure behavior, set the variable org--latex-preview-when-risky to a non-nil value.
  • Org mode now considers contents of remote files to be untrusted. Remote files are recognized by calling file-remote-p.

Kooha, the small free open-source screen recording app, release new 2.3.0 version a few days ago.

Kooha is one of the first apps support Wayland, the default display server in recent Ubuntu and Fedora workstation releases. Since GNOME’s built-in screenshot/screencast tool does not support recording audio, it is a good alternative to record full screen or rectangular area with microphone and desktop audio support. And, it can record your desktop screen into WebM, MP4, GIF, and Matroska formats.

In last 2.2.x release series, Kooha added new area selection UI for better Wayland support. In the new 2.3.0 release, the area selection window now is resizable, so you can have a bigger view when selecting recording area. And, previous selected area is now remembered to make it easy to redo recording last area.
