Palantir open source two libraries – Cinch and Sysmon

Cinch and Sysmon mark the technology platform first foray into open sourcing their products

U.S technology firm Palantir (named after the mystical omnipresent spherical stone from the world of Tolkien) have open sourced two of the libraries behind their integration and analytic business platform.

Cinch and Sysmon are now available for the community to test out, as Palantir wanted to return the favour from using code already readily available through Apache, Google and SourceForge. The two libraries in question are parts from Palantir’s main products – Government and Finance. Ari Gesher, the curator behind the project, discussed why they were adopting a more open approach:

We think it’s the right thing to do, to add our voice to the chorus of developers making software available to freely use, modify, and distribute. These two projects represent our first dip into the open source water – we’re just getting started. As time and other interests allow, we’ll be making other projects available to the dev community. 

We’ve chosen the Apache License, Version 2.0 to make our contributions as free from encumberance as possible – our hope is that many people will find them useful and build on top of them just as we have with our own software.

So the two libraries. Firstly we have Cinch – a Java library that simplifies types of GUI code. It comes into play when developing Swing applications, with the aim to MVC easier to apply than creating more Swing friction. Cinch uses Java annotations to reflectively wire up Models, Views, and Controllers, which likens it to iOS’s Cocoa.

Sysmon is a lightweight platform monitoring tool that gathers performance data when running on the JVM.  This data is gathered, packaged, and published via Java Management Extensions (JMX) for access using the JMX APIs and standard tools (such as jconsole). The team state it was originally created for use within their cluster monitoring server and is apparently ideal for anyone wanting to get data from a host platform into the JVM.

Both projects are under the Apache License 2.0 and available on GitHub. The team welcome discourse with the community regarding any queries with the libraries. Surely this is good news that another big tech company is finally seeing the importance of creating such an open dialogue with developers and we look forward to future offerings from Palantir.
