A part review / part guide to OS X from a Windows users point of view.
"An unexpected experience with the Mac came after I left it alone running in a dark room for the first time."
After recent issues with Windows Vista, and since a new updated version of Apple’s operating system had just been released [...]

The GM862-GPS is a hardware module with support for connecting to the GSM (mobile phone) network and receiving GPS position data. It also includes a Python interpreter, this combination makes it the perfect choice for building a tracker.
I purchased the GM862 Evaluation Kit (RS232 version) from SparkFun Electronics, at a cost of $309.60 (if [...]

I have been doing some development recently on the GM862-GPS embedded Python module from Telit.
I had the need to upload multiple files to it over the serial port, so I coded up a quick C# .NET application.
It supports setting the hidden file flag also.
It has an issue if you try to upload files over 7000 [...]

The serial port however that used to be standard on pretty much any PC (in 9 pin and 25 pin combinations) now seems to be [...]

I recently switched over to using Windows Vista / Office 2007 on my main PC - an Intel 2.4GHz Core 2 Duo, with 2GB RAM.
So far the experience has been extremely disappointing and frustrating.
On Windows XP I rebooted maybe once a week or so, with Vista I am rebooting all the time due to lockups [...]

I was also looking to gain some practical experience with [...]

During the Christmas break I found some time to catch up on watching / listening to the recordings made publicly available by conferences such as Blackhat, CCC, Defcon and HOPE.

On the Binrev forums, Natas recently mentioned he was interested in finding a way to view total concurrent calls on an Asterisk server at any given date / time from the CDR csv file.
I therefore decided to code up two php scripts.
The first acdrt.php (Asterisk CDR totaler) acccepts a single date / time, and will [...]

Willhackforfood.biz offered free disposable email accounts, unfortunately due to abuse we had to disable it a couple of months ago.
I made an attempt to get part of working again today. At the moment it does not do very much apart from allow you to create accounts, and view the raw mail messages, without any mime [...]
