Caching for Sensor Web REST-API

There are only two hard things in Computer Science: cache invalidation and naming things.

Phil Karlton

Caching is a common technique to improve the response time of a data source. A cache is a temporary storage for a most often acquired data. Caching is widely used in a proxying software such as Squid. The caching of network responses can provide a huge improvement to the response time. The latency of a network resource is much more greater than of a memory or a disk resource [Fig.1]. That’s why the caching is a “must-have” feature of network proxies.

In spite of the dampness and cool temperatures, it was actually great running weather for this year’s Firmenlauf this past Saturday. 52°North showed up with 2 teams for the 5k race. Once again we had some great results! Team 1 came in eighth among the Mixed Teams and Team 2 finished with an honorable 85th place among the Men’s Teams (see results below)!

Congrats to all!!! (more…)
