Choosing a router for OpenWRT 14.07 Barrier Breaker

The OpenWRT project is about to release version 14.07 of their alternative home router firmware with many new features like native IPv6, support for NAND flash devices and a new web GUI.

AsiaBSDcon 2014 – Deploying FreeBSD systems with Foreman and mfsBSD

My first trip to Japan ever was connected with speaking at the AsiaBSDcon conference on March 15-16 at the Tokyo University of Science.

This time I had a completely new topic, my talk had the title “Deploying FreeBSD systems with Foreman and mfsBSD”. My special thanks go to Hiroki Sato and George Neville-Neil who have organized this successful conference.

Facebook’s HipHop Virtual Machine in FreeBSD ports

Great news for PHP administrators and site architects – the Facebook’s HipHop Virtual Machine (HHVM) version 2.1 is now available in the FreeBSD ports tree. The port is available under lang/hiphop-php and is limited to the amd64 architecture.

HHVM is an open source virtual machine that can act as a standalone server that can run PHP sites. With it’s just-in-time compilation approach PHP sites receive a reasonable speedup.

Special thanks to vanilla@FreeBSD.org who has helped me making this port work. Our patches have been submitted to Facebook via GitHub. Continue reading
