Yuki-iptv – An IPTV player with EPG support (Ubuntu PPA)

Last updated: May 5, 2024 — 1 Comment

Linux is getting more IPTV player applications in recent years. Here I’m going to introduce yuki-iptv, a new one with EPG support.

Personally, I prefer hypnotix which is developed by Linux Mint team, since it has a large list of built-in TV channels. But if you want more features, then yuki-iptv is a good choice to try out.

The IPTV player does NOT provide any content or TV channels. User has to manually add M3u / M3u8 / XSPF playlists (see github.com/iptv-org/iptv) and/or TV guide address via config dialog.

Besides basic M3u / M3u8 / XSPF playlists support, the app also support viewing unencrypted streams UDP (multicast), HTTP, HLS (M3u8), XTream API, as well as TV program (EPG) support in XMLTV and JTV formats.

MenuLibre – Advanced tool to Edit App Shortcuts in Start Menu

Last updated: October 12, 2024 — Leave a comment

Need a tool to edit your apps in the start menu, main menu, or Gnome overview search results? Try MenuLibre!

In most Linux, all app icons you see in start menu, dock launcher, and the desktop, are handled by .desktop config files. By editing the file, you can change the app icon, name, hide the app, add right-click menu option, and choose which file types to be associated with.

I’m written about how to configure .desktop file using a single command.

For graphical ways, there are quite a few apps to do the job, and here are 3 of them:

Arronax – well known, but seems not being updated. Though, it’s still working.
AppEditor – Elementary OS style tool to edit desktop menu entries. However, lacks pre-build packages.
MenuLibre – the one I’m going to introduce in this tutorial.

MenuLibre is an advanced tool written in Python and GTK3 toolkit. With it, user can get started by either searching or browsing in left to select app to edit, or click “+” in top left to create new menu entry for your app.

This simple tutorial shows how to disable (or auto-delete) “recent” files tab in left side-bar of file manager in Ubuntu 24.04 & 22.04.

It’s useful for user or applications to quickly re-open recent edited files. However, when working at a public place, it can be better to disable this feature since it may contain sensitive data.
