semperos - Overview

I'm Daniel (semperos) 👋

I work as the Head of Engineering at Shortcut.

Clojure is my primary programming language, been using it since 2010 and making a living with it since 2013.

💻 My Open Source Work

• Ari: Array Relational Interactive Programming
• Metazoa: Tools for viewing, testing, searching, and querying Clojure metadata
• shortcut-repl: A REPL & CLI for Shortcut (Dart)
• clj-webdriver: (Unmaintained) Clojure API for Selenium-WebDriver

Learning, experiments, and toys:

• Gershwin: Stack-based, concatenative programming language with a Clojure runtime that targets the JVM
• rankle: Experiments with data rank and tables in Clojure, inspired by J and Q
• river-crossing-spec: TLA+ Specification for the "Wolf, goat, and cabbage" puzzle
• AsIf: Language implemented as a Clojure transducer
• Shackle: Stack-based language, implemented in the web browser
• webdriver-logic: Logic programming API for testing web applications using clj-webdriver

💾 Technology I Use

• Clojure for most of the professional code I've written
• Goal for day-to-day data analysis, HTTP API interaction, and scripting
• Julia and J for data analysis
• Glamorous Toolkit built on Pharo Smalltalk for moldable development
• LaTeX for authoring documents of all kinds
• Ruby for writing scripts to share with others
• sops for managing secrets locally
• fish as my primary shell
• WezTerm and Alacritty as terminal emulators
• tmux for multiplexing
• Emacs, traditional bindings for Lisp-adjacent work, Vim bindings via evil-mode for everything else
• NeoVim for text editing at the terminal
• Visual Studio Code for most non-Clojure development
• macOS-specific:
  • Rectangle to move and resize windows
  • Maccy for clipboard management
