Emitting LLVM-IR intermediate-representation language: experimentations & explorations

inspired by the work on gogen-dump, a more carefully designed, generalized and principled Go code-gen framework

JSON schema (JSD) files are great for exposing interchange formats of REST APIs, DB schemas, custom protocols etc. to external code. Given such a JSD definition, this package generates all the Go code necessary to load JSON documents of the therein-described format into the correct, fully commented/documented (likewise from the JSD) runtime data struct(ure)s.

A commissioned Go package providing a higher-level API for simplified RabbitMQ message-queuing by wrapping-abstracting-streamlining streadway/amqp under the hood.

A generalized IDE back-end for plugin-powered text editors: multi-editor (only VS-Code for now, Sublime planned) and multi-language (Go + Haskell for now, easily-extensible)

A DOM API library for handling XML Schema Definition (XSD) documents in Go code; includes a source-code generator to instantly create 'native Golang bindings' for any given XML Schema Definition

All the general-purpose programming libraries I was missing in vanilla Go; includes imaging, hashing, DB, file I/O, networking, maths / numeric and string-processing helpers that I found indispensible in real-world Go programming

Utility library for cross-platform, core-profile OpenGL graphics programming in Go — 'sane no-overhead wrappers' for real-time use-cases

A DOM API library for handling Collada documents in Go code; supports Collada 1.4.1 and 1.5

I wanted constantly changing quotes in email signatures, so I wrote an app for that. Before long, I had a neat quotebook utility to offer to an appreciative audience increasing steadily. Took care of the website, support, feature requests and documentation for a while, until before long most folks moved over to web mail.

A big Sudoku craze swept Europe in the mid-2000s. To study and experiment with solver algorithms, I developed a Windows game that quickly became quite popular 'shareware' (to the point of getting pirated). As user numbers piled up, so did interesting and challenging feature requests; from a solving assistant to full-fledged printing capabilities for making mags and books; plus the website, documentation and tech support kept me busy. As the fad faded and users flocked to browser and phone apps, everything was handed over to Pasadena-California-based "Diangy Systems" who had big plans for it...

This might have been one of the first online shops in town!
