Some things I found to be useful for daily programming.
- Geany: very fast IDE, not the memory and CPU monsters out there like Eclipse/Netbeans.
- Valgrind: code analysis tool, I use mainly the memory checker and the profiler.
- KCachegrind: graphical profiler presenting runs of valgrind performance checks in a nice way.
- xxdiff: 2 and 3-way graphical diff tool, I use it because of nostalgia (aka: I got used to it).
- Gengetopt: parser for command line options
- dbmodel: a very neat database modeller with PDF and image export.
- XMLStarlet: XML processing on the command line for fast and dirty XML processing
- JQ: JSON processing on the command line very much alike as with XMLStarlet
- openSUSE Build Service: for building release packages in the cloud.
- Travis CI: for continuous integration on Mac OSX.
- Using libvirtd now instead of VirtualBox (sorry, Oracle). Main reason: it's still a little bit un-ready round the edges but hey, it's really open source. :-)
- LXC: lightweight and surely nicer to use than Docker (IMHO). Still a little bit alpha quality though.
- unison: file synchronizer, I'm using it since years to sync my home directory between three or four machines, sort of a very easy backup.
- The backup from the local LAN to the cloud happens via FTP and some copy jobs within Bacula.
- The Pragmatic Programmer: an absolute must for every programmer.
- The Mythical Man-Month: an absolute must for everybody doing a project.
- AntiPatterns: Refactoring Software, Architectures, and Projects in Crisis: avoid mistakes by learing from bad examples.
- Ion3: tiling window manager with
strong keyboard and Lua scripting support. Sadly the original author
got into fights with the open source community :-(
I'm currently using the fork Notion.
Read http://raboof.github.io/notion/ if you want to learn how to use such a window manager.
- Joe: my editor for all quick editing jobs. Having used a lot of Wordstar in my youth, jstar is the editor I can't get rid of in my brain. :-)
- meh: as fast and easy an image viewer can possibly get.
- MuPDF: an equally fast PDF/XPS viewer.
- Trojitá: a simplistic and really fast mail reader for IMAP accounts. For long-term archiving of email I'm using a combination of OfflineIMAP and good old Mutt.
- Seamonkey: back to old SeaMonkey, fast, no clue what they did to Firefox to make it so slow.
- irssi: for chatting (terminal)
- calcurse: for appointments/calendar (terminal)
- newsboat: a RSS feed reader looking like mutt
