Telegram Desktop is the official client for Telegram Messenger. It's also open-source. The source code is available on Github. We'll be installing Telegram Desktop from the official repository of Arch Linux on Arch-based distros. There is a community package called telegram-desktop that pretty much automates the installation process for us.
GNOME Web (aka Epiphany) is the default web browser for GNOME desktop environment. Although the popularity of it is not growing significantly, it's one of my must-have browsers. The reason behind that is because it's the few WebKit based browser on Linux still maintained, comes particularly handy when testing websites.
Vivaldi is another Chromium based browser, but not fully open-source. And to my surprise, Manjaro Cinnamon actually ditched Firefox for Vivaldi as their default web browser. In case you're an Arch Linux user or didn't install the Cinnamon edition of Manjaro, this tutorial will cover how to install Vivaldi in single line of command.
If you encounter an error like bash: ./script.sh: Permission denied when executing a bash (shell) script, meaning the script file itself is not permitted to execute. And it makes no difference even if you run it with sudo. To fix this, we'll be using the chmod command on Linux to modify the permissions of the script file.
The default file permission on Linux is 777, which means everyone can read, write and execute the file. It's fine for most of the scenario, but it's another story when it comes to SSH private key. If you try to establish an SSH connection with a too open private key, WARNING: UNPROTECTED PRIVATE KEY FILE! will be shown.
Chromium is an open-source web browser, also the core of many popular browsers like Google Chrome, Brave, Vivaldi and even Microsoft Edge. There are people actually using Chromium in their day-to-day work, since it's the only way to experience the bleeding edge features of the core.
Brave is an open source web browser based on Chromium. It has grown fast in the past couple of years, and probably has something to do with its cryptocurrency Basic Attention Token (BAT). BAT has been integrated into the Brave browser and allows users to earn it by browsing ads, or giving it to the content creator as tips.
GNOME desktop has IBus integration by default. To set up the Zhuyin/Bopomofo (注音) input method is quite easy. On Arch-based Linux, there is an AUR package called ibus-chewing which is a Chinese Zhuyin/Bopomofo engine for IBus. The engine uses libchewing(酷音) under the hood. It's also a very popular input library in Taiwan, even on Windows systems.
A lot of extensions stopped working after GNOME 41. This is because the maintainer didn't mark their extensions as compatible with the newer version. But that doesn't mean it won't work after the update. To force the extensions to run even if they're outdated, we'll need to do some tweaking to gsettings.
PC/SC (Personal Computer/Smart Card) is not implemented by default on Arch-based Linux. To use your USB chip/smart card reader, we'll need some essential packages (drivers, tools, etc.) from the official repositories.
Debian/Ubuntu-based Linux distros use .deb file to distribute and install packages, but Arch-based Linux doesn't have that kind of feature built-in. With tools like debtap, we'll be able to convert a .deb file into an Arch Linux package with PKGBUILD then install the package with pacman.
