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.

When using pip command to install a Python package in Ubuntu 24.04 will output “error: externally-managed-environment“. Here are a few workarounds to ‘fix’ the issue.

As the terminal output shows you, it’s the change due to PEP 668. Since Ubuntu 23.04, it recommends Python-specific package management tools (e.g., pip) to install packages using a virtual environment, to avoid conflicts to packages installed by OS package managers. Though, user can still force pip to install into interpreter’s global context just like before.

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.

After installed Enlightenment desktop in Ubuntu 24.04, the classic Xorg session is missing from the login screen. And, here’s a quick fix for it.

Enlightenment released version 0.26.0 last year with experimental Wayland session support. Which is however missing the Xorg session in the login screen due to bug.

Why the Enlightenment Xorg Session is missing

Ubuntu now finds the desktop sessions from both /usr/share/wayland-sessions/ and /usr/share/xsessions/ directories. And, the former one has higher priority!

Enlightenment 0.26.0 installs its session entries in both directories with same name. In the case, only the one for Wayland is in active, while another for Xorg is ignored and hidden from login screen.
