open source – articles – email

Also known by friends as Peo, and parren on IRC and other online media. I live near Zurich in Switzerland. I’m a father of four, a self-taught computer programmer, a hobbyist boulderer and percussionist, and an old-school quad roller skater. You can reach me at this email.

Work

Since 2011 I’m a software developer at Google Switzerland, where I work on YouTube and Google Ads.

Before I worked as a freelancer under the name of codewise.ch, mainly for Abacus. And before that I was co-founder and tech lead of Opus Software, where I conceived the database application framework Atlas.

Open Source

I published a remote controller for the Hoval Ultrasource heat pump.

While freelancing, I contributed to open-source, including

an efficient distributed protocol for determining missing commits in Mercurial, and
the Abacus Formula Compiler, which extracts computation models from spreadsheets and compiles them directly to JVM byte code.

Literate Testing

I’ve been a public exponent of Literate Testing. I spoke about it at Devoxx (photo, slides) and ESEConf (slides ). I wrote a comprehensive article on citing sources, and created the open-source tool JCite around it.

Articles

I wrote articles about threaded chat, command line UIs , and other topics.
