owlsnearme source code on GitHub. Here’s the source code for our new owlsnearme.com project. It’s a single-page React application that pulls all of its data from the iNaturalist API. We built it this weekend with the SuperbOwl kick-off as a hard deadline so it’s not the most beautiful React code, but it’s a nice demonstration of how React (and create-react-app in particular) can be used for rapid development. # 4th February 2018, 10:33 pm

10K Apart Contest: Cheating by Compressing Your JavaScript and CSS to PNG Images. Fascinating hack: transform your JS and CSS in to coloured pixels, save the result as a PNG to benefit from PNG’s built in compression algorithms, then read the data back out of the PNG and convert it back to text using JavaScript and canvas—all to reduce the on-disk filesize when entering the 10K app competition. Alex’s GithubFinder entry is worth checking out too. # 23rd August 2010, 9:45 am

Introducing the YUI 3 Gallery. Write a plugin for YUI3, BSD license it and sign a CLA and Yahoo! will push your module out to their CDN and make it loadable using the YUI().use() statement. They’re coordinating the submissions using GitHub. # 4th November 2009, 11:14 pm

Introducing BERT and BERT-RPC. Justification for inventing a brand new serialisation protocol: Thrift and Protocol Buffers both use IDLs and code generation, XML “is not convertible to a simple unambiguous data structure in any language I’ve ever used” and JSON lacks support for unencoded binary data. The result is BERT—Binary ERlang Term—which extracts a format from Erlang in much the same way that JSON extracted one from JavaScript. # 21st October 2009, 10:11 pm

Scriptlets—Quick web scripts (via) From the prolific Jeff Lindsay, a pastebin-style tool for short server-side scripts written in Python, JavaScript or PHP that executes them within a Google App Engine powered sandbox. The Java code that implements the service is available on GitHub. # 13th August 2009, 1:51 pm
