dynalogin 1.0.0 has finally been released. It is available now from the dynalogin web site

Adapting the Swisscom Piccolo (Motorola 7640-47) Router for bridging and other ISPs


The Piccolo is actually quite a powerful router. Unfortunately, Swisscom has crippled it, removing fundamental configuration options from the web management interface, and even worse, breaking some of the (undocumented) command line configuration options.

At a bare minimum, the router can be turned into a bridge/modem, enabling more powerful functionality to be implemented using a wifi router with OpenWRT or a similar solution.

devroom video recording at FOSDEM 2013

The problem statement

There have been some terrific presentations in the devrooms at FOSDEM every year that I have attended, and sadly not everybody is even able to get in the room (or be in three places at once to see all the presentations they want)

The solution

The solution, of course, is video

FOSDEM: looking for Freedom

This year I was thrilled to be able to contribute to one of Europe's leading free software community gatherings, FOSDEM, in Brussels. The weekend included assisting the telephony devroom team spearheaded by Matt Jordan of Digium and some productive face-to-face discussions about DebConf13.

Will 2013 be the year of Bitcoin?

The economy has dominated the news in recent years, whether it was the bankruptcy of Iceland, the Greek situation or the massive US fiscal cliff. One trend that has been nipping away at the financial press and demanding a share of the limelight is the rise of Bitcoin

2012 has seen Bitcoin taking leaps and bounds as it approaches mainstream use:

The sinister secret in every hard disk

These are not my words...

"The job of any filesystem boils down to this: when asked to read (data), it should return the same data that was previously written ... Incredibly, most filesystems fail this test. They depend on the underlying hardware to detect and report errors. If a disk simply returns bad data, the average filesystem won't even detect it."

Migrating a SourceForge project from Subversion to Git

Many projects are now contemplating the move from Subversion to a more modern, distributed version control system (VCS) such as Git or Mercurial.

Until recently, the default strategy was to take the whole source repository from the SourceForge site and import it into the rival GitHub site.

Scalable and convenient Ganglia Nagios integration

Is simplicity a priority for you in network design? Would you prefer to have a single, lightweight monitoring agent that can provide both performance and availability metrics, while guaranteeing the minimum impact on the hosts being monitored?

Nagios is phenomenally popular for network state monitoring, while Ganglia has become the go-to solution for performance monitoring (using the legendary rrdtool to store and graph metrics).

SIP or Jabber?

Three open protocols (SIP, Jabber/XMPP and H.323) have been fighting it out to become the Internet equivalent of a phone call. What does this mean for you?
