Looking at my Raspberry Pi Zero and maybe being partially inspired by the now defunct "One Laptop Per Child" project from a few years ago, which aimed at building a laptop for under $100, I wondered if a usable computer could be created out of the Raspberry Pi Zero. Or maybe it's just the challenge of seeing how far this tiny computer can be pushed that had me wondering whether this was even

Part seven of the series detailing the OWASP top 10 web application vulnerabilities with a focus on password hashing. (See intro) "Insecure cryptographic storage" relates to a number of aspects, but I think that it can be broken down to two main areas: Encryption and Hashing. As these are similar in some respects and are often both used together, there's a bit of confusion around what they are.

There seems to be an amusing correlation between the history of the fight between Kevin Mitnick and Tsutomu Shimomura as portrayed in the movie Takedown and the goings on with Anonymous and HBGary. In the same way as the "expert", Shimomura, was hacked by Mitnick, HBGarry was hacked a while ago after annoying the group. By means of getting in through the company website via an SQL injection

Here's an excellent series of articles on an "average" Windows user, trying out Ubuntu Linux for the first time. I think his experience closely mirror many others, including mine. This was just one person's experience but I think his final conclusions may give interested people some perspective on the OS. http://www.pcworld.com/businesscenter/article/229187/

Finally, Microsoft seems to making headway with Windows 8 and it seems to be heavily influenced by the Windows Phone 7 interface. A video has been released which showcases some of the new features and it looks pretty awesome. It's very different to the usual start menu/ windows/ desktop environment which has been around since windows 3.11.  It quite obviously has to compete with the

Microsoft has just announced that it will purchase Skype for $8.5bn. On the surface of it it seems as though it's a great purchase with possible integration with Xbox, Windows Phone 7, Live.com etc. But has it come at too high a cost? In 2009, 70% of Skype was sold for $2bn. 2 years later, it's bought for $8.5bn? I doubt that Skype's value has increased to the degree which justifies the price

I faced an interesting question recently in building SharePoint based InfoPath forms. The problem was that a drop down field was being populated from a SharePoint list which could potentially have 50+ values, making the control cumbersome to use. The aim was to filter the values in the drop down based on another drop down field where there was a relationship between the two. So how do you build

In my review of Kubuntu 10.10, I closed in saying that I probably wasn't going to keep it for very long. There seemed to be a few bugs in the UI, with some of the windows tearing.
