Projects developed and maintained
NetFlow · Scala / Netty
A Scala/Netty NetFlow collector developed by Franz Bettag, with Redis and Cassandra backends and external contributions he merged in 2017 and 2018.
Solarium · Scala / Solr
A derivative developed from Foursquare’s Slashem, adding write operations and caching. The work is documented in this project; it does not establish that Foursquare accepted these changes.
Scala ACME · 2016–2017
A project of my own: a Scala/Netty client for ACME and Let’s Encrypt. Client development, not a claimed role in the Let’s Encrypt project.
Collaboration on debugging
Netty · 2013 · #1874
Bug report with a maintainer-confirmed fix: a maintainer thanks the reporter and confirms the correction. The thread documents debugging collaboration, not a CVE or a security-vulnerability classification.
Netty · 2013 · #960
Bug report with reproduction and a follow-up test: Franz Bettag supplies a reproducible UDP case and subsequently confirms that the fix works. Not counted as a security finding.
