Curiosity question: What is a piece of software that you really like, and what makes it better (for you) than the alternatives you've tried? 
(Any category of software is welcome, and so is any rationale - please do not argue with people in the replies!)
@joepie91 where do I start?
NixOS: It gives me peace of mind because, frankly, I can't fuck up with it (unless I try really hard). Also, modules often (not always) make it easier to set up a new sofware I'm not familliar with. And sharing config between hosts is nice.
@joepie91
Emacs: I love vim, the concept of modal text editing is great, but for note-taking a la markdown emacs org-mode (with vim keybindings) suits me better. I don't use most of those "orga features", but I like that it can render LaTeX previews inline (something vim just can't do because terminal), as well as display the results of code blocks automatically.
Maybe I'll post some more during the day.
@joepie91 #kmail #kdepim is massively underrated in my opinion.
It is a blazingly fast (copes well with with >10k mails per folder), well-integrated (w/ support for groupware features) mail client. Out-of-the-box support for GPG (using the system GPG implementation) and S/MIME (for whoever needs to suffer that).
Except one thing (KDE Bug#373040), which is that it does break long URLs when composing in plaintext mode, something Thunderbird *does* get right. Can't have everything I guess.
Before kmail, I used Thunderbird (for more than a decade, but I needed something which worked well with a HiDPI factor of 1.5 in the year 2016) and Evolution (tried it briefly, it broke my inbox by duplicating half my mail, never going to touch that ever again).
@joepie91 I don't think I have that. But there is some software that doesn't make me want to cry all the time but just sometimes!
- Joplin is pretty good for personal notes and todos. It's proper markdown (with checklists and tables!), but organized a bit better than not at all.
- HedgeDoc on the other hand is great for collaborative editing.
- Syncthing does a wonderful job of syncing files without eating up ridiculous amounts of resources, and has a pretty nice web GUI and (third party, but also open) apps.
- Toggl Track does one thing well (tracking time) and doesn't get in the way.
- Firefox for Android is actual real Firefox, on Android! With some dancing it's even possible to install extensions.
- StreetComplete is the first app that actually made me go walk around the neighborhood. It's like collecting pokemon but you're improving OSM instead.
- Systemd has its fair share of problems, but it's certainly nice to use.
- Fish is simple and easy to switch to from Bash, but has much better completion.
- I use Arch btw. Voluntarily. Will not elaborate.
@joepie91 @binaryninja . the UI is straightforwards and gets out of your way, the analysis is clever with only a medium-sized bag of hacks^Wheuristics, and the architecture is well thought out and very extensible
@joepie91 dc. It's right there on the command line, so less distracting than flipping to a calculator.
@joepie91 Poedit, for translations. I really like that the interface is quick and accessible, with very simple tab order and quick keyboard shortcuts to do all necessary tasks.
