Uses

Here you can find the software, tools, and hardware I use to do my thing! Perhaps one of them will be useful for what you do as well.

I use a desktop to run Qubes OS and a ThinkPad T480 laptop to run OpenBSD. I've been running Qubes OS as my primary operating system ever since switching from Windows 10 in Janurary 2019.

All of the below software is open source (with minor noted exceptions) which accounts for the majority of software I use. When I have to use closed source software, usually for work purposes, I run it isolated in its own virtual machine.

Editor & Terminal

  • VSCodium (open source Visual Studio Code)
  • MarkText as a markdown editor for note taking
    • Ghostwriter if something that's available from official Debian repositories is required
  • wxHexEditor (built from source w/ patches) for viewing, editing, diffing and tagging binary data
  • Meld for diffing text files
  • diff for testing if files differ between folders
  • ZSH + custom dotfile w/ plugins from the official Debian/Fedora repositories
    • See my dotfiles repo (coming soon)
  • IPython as a Python REPL
  • Tilix as a tiling terminal emulator
  • tmux as a terminal multiplexer (usually over SSH) + custom dotfile
  • ShellCheck, Clippy, Pylint, Black, and Mypy for source code linting and formatting
  • GNU coreutils and GNU/LLVM binutils for all kinds of data introspection and alteration
  • htop for performance and process monitoring
  • progress for keeping track of long running (and I/O bound) coreutil commands
    • It works by monitoring file descriptors in /proc
  • Gedit
  • Vim (on Linux and Windows, the latter through MSYS2)
    • Run vimtutor to learn how to efficiently edit files with Vim shortcuts
  • Notepad++ on Windows

Software

  • Firefox
  • KeePassXC as a password manager on desktop
  • KeePassDX (Android) or Strongbox (iOS)
  • Signal or Wire as secure and private messaging clients
  • LibreTube (in "Audio only mode") for music streaming on Android
  • Materialistic (Android) or Hackers (iOS) for mobile Hacker News clients
  • GIMP/Krita/Inkscape for photo/vector editing
    • Occasionally, Photoshop (proprietary) in its own air-gapped Windows VM to use their selection algorithms for background removal
  • Shotcut for video editing
    • Very easy and intuitive to use, gets editing done quickly
  • Handbrake for converting between video formats
  • FFmpeg for doing some more video processing
  • OBS Studio for recording/streaming
  • ScreenToGif for easily recording short clips (w/o audio) on Windows (includes a few built-in editing features)
  • Byzanz for simply recording videos on Linux
    • Minimal (doesn't use FFmpeg; just X) and works
  • Exodus for quickly relocating (dynamically linked) Linux binaries and all of its library/data dependencies across machines
    • Effectively makes Linux (ELF) executables as portable (or "backwards compatible") between OS versions as Windows (PE) executables tend to be so you can have the best of both designs
  • Docker or Podman for containerization
  • LibreOffice
  • Thunderbird
  • Wireshark (and TShark)
  • ssdeep for quickly finding out how approximately related multiple files are (using a fuzzy hash)
  • Diffoscope for zooming in on the differences of complex data structures between files
  • Dash or Posh shell for writing minmal and secure POSIX shell scripts
  • strace for debugging program errors
    • Often my next step after increasing verbosity, checking logs, searching up the error message, and trying ideas fail
    • Reading/grepping source code or binary strings may come after this
  • Socat for connecting things together
  • Tinyproxy as a simple HTTP proxy server for use with Socat
  • Git
  • QDirStat
  • WinDirStat on Windows
  • MSYS2 Bash shell (and Mintty terminal) on Windows as a CMD replacement and for coreutils (also prefer this over long object-oriented PowerShell commands IMO)
    • With a minimal dotfile that improves Windows integration (among other things)
    • Enables the same commands to work across my Linux and Windows VMs
    • Comes with a real package manager (pacman) for installing packaged Windows programs
  • 7-Zip on Windows for compressing/archiving and file hashing
  • Rufus for creating bootable USB drives on Windows (e.g. from an ISO file or disk image in dd mode)
  • PE Tree and PEStudio for initial analysis of a PE (e.g. EXE or DLL) file (the latter is closed source and Windows-only)

  • System Informer
  • Sysinternals Suite (closed source) on Windows
    • Particularly Process Explorer and Process Monitor
  • Visual Studio (closed source) on Windows
    • Some of the tools that ship with VS such as dumpbin.exe for dumping in-depth COFF/PE info

  • IDA for reverse engineering some Windows binaries (closed)
  • WinDbg (Preview) for debugging on Windows (not open source)
    • SOS debugging extension (closed, by Microsoft) for managed code (e.g. mixed CLR programs or fully managed .NET programs)
  • Ghidra as a decompiler on Linux and Windows
  • Radare2 utilities
  • NASM as an x86 assembler and disassembler

    • With a minimal and secure configuration
  • rEFInd boot manager to intelligentlly scan (even non-FAT drives) for UEFI boot entires and present them graphically
    • The boot manager that comes with my Gigabyte motherboard is very poor not even providing an option to boot from a custom EFI file
    • Tiny and generally solves all my booting problems (it's saved me from malformed/corrupted boot partitions)
  • Qubes OS for all general purpose computing
  • OpenBSD for remoting into my Qubes OS machine from anywhere in the world
    • Securely set up SSH tunnel to Dom0 with TigerVNC inside
