Games

Simple memory game implemented in different ways in Javascript:

• Memory (ES2015, CSS3, HTML5),
• Memory (ES2016 with customElements, ShadowDOM),
• Memory (ES2015 with Angular 1.6),
• Memory (ES2016 with React and Flux).

Game #2 uses JavaScript's new customElements v1 (since Chrome 55) and Shadow DOM v1 (since Chrome 53 and until Chome 80 or so) APIs. In plain ES2015 and AngularJS, using will-change: on card elements improves animation smoothness somewhat.

Playing with Rust, two simple games for the terminal:

• Termtris and
• Termsnake

Websites

Some of my current sites.

• Newsdiffs (Python source) Collect the text content of news articles regularly to spot text changes over time.
• Graniteland.com and Graniteland.de Natural stone database and database of natural stone industry related companies.
• ReddMeet (Python source, partial rewrite in Rust, outdated Chrome extension) A Reddit dating site that matches users based on interest in similar subreddits. Not updatd in a few years. Meanwhile, Reddit changed its design and focus, so this is based on old.reddit UX.
• Messen-Kalender.de Searchable (and by now outdated) trade show database that is entirely pre-rendered, with a back-end that is based on static HTML and JSON files.
