Linux

Thrown away your current ssh client and get

https://xpipe.io/

edir to mass-rename

fd is more convenient than find

aria2 makes downloads go brr with parameters -x 10 -k 5M and is integrated with multiple tools like yt-tlp, yay

Oh, and pass for password-management

ssu makes root console tools password-less. That and rdo for gui-tools (both a bit over 100 loc) made me uninstall sudo.

Emacs.

Emacs is an app platform in and of itself, and the vanilla installation comes with dozens of its own apps pre-installed. Like how web apps are all programmed in JavaScript, Emacs apps are all programmed in Lisp. All Emacs apps are scriptable and composable in Lisp. Unlike on the web, Emacs encourages you to script your apps to automate things yourself.

Emacs apps are all text based, so they all work equally well in both the GUI and the terminal.

Emacs comes with the following apps pre-installed:

• a text editor for both prose and computer code
• note taking and organizer called Org-mode (sort of like Obsidian, or Logseq)
• a file browser and batch file renamer called Dired
• a CLI console and terminal emulator
• a terminal multiplexer (sort-of like "Tmux")
• a process manager (sort-of like "Htop")
• a simple HTML-only web browser
• man-page and info page browser
• a wrapper around the Grep and Find CLI tools
• a wrapper around SSH called "Tramp"
• e-mail client
• IRC client
• revion control system, including a Git porcelain called "Magit"
• a "diff" tool
• ASCII art drawing program
• keystroke recorder and playback

Some apps that I install into Emacs include:

• "Mastodon.el" Mastodon client
• "Elfeed" RSS feed reader
• "consult" app launcher (sort-of like "Dmenu")

Syncthing and KeepassXC for syncing 2FA between devices. (I use Bitwarden for passwords)

Emacs is the only app you'll ever need once you've mastered it.

Not exactly unheard of:

Terminal:

Vim or Neovim, Tmux or Zillij.

Web browser:

Firefox or a fork, but personally I’m fine with the standard Mozilla offering with a couple of extensions.

Photos:

Big fan of darktable as a lightroom replacement.

Analogous to the Krita post, I am surprised nobody seems to know KolourPaint. It's similar to MS paint. I use it, when I need to make a quick sketch, whiteboard style, e.g. when sharing my screen with a coworker.

Otherwise, I really must have Dolphin and Okular.

I love dolphin's split mode (quickly toggled with F3) and its ability to seamlessly navigate all kinds of protocols for my NAS, webdav for nextcloud storage, MTP for the phone...

Okular has annotations which have been super useful to me. And it's so easy to switch between viewing single page, two-page and multi-page. Which is great for skimming text documents and presentations. The auto reload ability is great when iterating on a document (e.g. latex doc or matplotlib chart).

Otherwise, of course firefox and thunderbird, not much to say here Please don't use chrome. It's market share makes Google the de-facto owner of www technology. But I guess I'd be preaching to the choir here.

I use XSane and TheGimp to scan and edit my paintings, Firefox with privacy extensions to browse, VLC to play videos, Gnome Mahjongg to waste time playing. I used to use Resolve to edit videos, I'll soon start using Kdenlive. As a visual artist I have a thing for film emulation that Kdenlive can't do, but it's something I'll have to leave behind.

Htop vim and ncdu to name a few terminal apps.

I don't know about you specifically, but I'm surprised how many people haven't heard of Krita, a FOSS image editing app with an optional AI Image Generation plugin.

Profanity & Dino are nice chat clients

K9S, it is a TUI kubernetes manager that really integrates well into my workflow.
