Over the years, I've written many apps and utilities for myself or others (that didn't end up get used). These are the interesting ones I remember. Many not quite complete/usable. Other than hackerer.news none of them are 'up' and running. Some have and others haven't been published as opensource.
https://hackerer.news HN viewer (source[0]): I use daily so I can see today's top stories in reverse chronological order with mainstream topics grouped at the bottom, leaving niche/deeper stores at the top.
Qwickly[1] keyboard layout: I use all the time as an easier to learn and more comfortable to type than Colemak/Tarmak. Made macOS and Windows packages. Linux I didn't do as I'd need to do 2 for text and graphical (X11) and didn't learn how. If anyone has simple instructions I can follow, link me.
SafeQL[2]: Java type-safe SQL expression composer that reduces constant expressions and eliminates N+1 queries loading associations by always operating on set relation or array of models.
Moja[3]: Composable computation pipelines for Java: Async, Lazy, Option, Try, Result, Multi (List), Stated, Reader, Logger, Writer.
Gitgrep.com[4] Opensource SaaS version of etsy/houndd (now called hound-search).
StatusPages.me: Status page aggregator with dynamic javascript for scraping each source using selector expressions.
movies to watch aggregator: with links to sources to watch. It was hard at the time to get 3rd party deep links into streaming services so included some torrent magnet hashes. Got a DMCA phone call, so took it down. Combined thumbnails, summaries, actors(?), imdb ratings, links.
Java2cpp: Translate a moderately sized java app with test suite to C++, not 100% required final manual fixups.
Swift2java (or maybe it was java2swift, it's fuzzy now): translate Swift to Java obviously, using ANTLR4. Not 100% required final manual fixups.
Gui2log: Write an ASCII rendition of on-screen GUI widgets into an application log file when form submitted, so users couldn't complain that they saw X, but got Y.
some basic stats/ML algorithms: k-nearest neighbour, RNN back-propagation, etc?
Java in-memory DB: Small SQL-like memory tables with indexing/searching.
wwwsqldesigner: This exists as opensource and I extended it to infer foreign key relationships based on naming conventions used in a MySQL schema. It was great for zooming around a large ERD.
Quicklog: combination of distributed microservices parent/child span logging and generated high level events shown as a sequence diagram. Integrated with Loggly for full/verbose logs of selected high-level events.
Pcl2bmp downscaler: Reduce high resolution HP LaserJet (PCL5) printed to file to lower resolution bitmap pages for screen display (before retina DPI was common). It aimed to shrink same-color areas and preserve black/white transitions while reducing.
