Low Power Home Server

Wed, 10 Nov 2010 01:26:44 +0000

For a long time I’ve searched for a way to replace my aging ASUS WL500gx which looks like the WL500g but packs 2 USB2.0 ports and has extra RAM (64MB).

The ASUS has been my home server for a long time now (>5 years), providing me with a reliable SSH server through which I can proxy my Internet usage whenever I’m in a public space, with a small webserver in which I keep Internet and Power Usage statistics and for a brief period of time was my printing server (it was replaced first by an Apple Airport Express, and more recently by ZON’s HUB).

Daidalos Project

As promised, here I am reporting back on Project IST-Daidalos which had it’s final audit in the beginning of the month.

First things first, here is the video of the project describing what the project is about:

On a personal note I would like to say that I’ve been involved in this project for as long as I’ve started my research career, which is just a bit over 5 years ago. This project enabled me to meet people in most parts of Europe, to know their way of doing research and of course to learn from them and with them. Strangely enough: I was getting sick of this project :D

What's with Cisco and the Kusec?

Wed, 21 Nov 2007 12:20:55 +0000

This week my ARA (Advanced Networks class) lab students got the chance to work with some recent equipment acquired by the department. The equipment consists of several enterprise grade CISCO networks wireless units (Access Points and Network cards) that most of them will eventually deploy in their future careers, and have during these labs classes the chance to a have a first contact with. The curiosity here lies on the fact that Beacon Periods in CISCO equipments do not use “standard” time units.. they use something called Kusec. What ?! a Kilo Micro Second ? In my days (and guess wikipedia days…) Kilo meant 10³ and Micro meant 10^?6 which would mean 10^-3 or good old Milli. So where from does Kusec comes from? Kusec equals (according to CISCO) 1024 microseconds… hmmm shouldn’t it be then a Kibi Micro Second ? and therefore Kiusec ? And whats wrong with miliseconds ? All other vendors have the Beacon Periods configured in milliseconds…
