Sensor cleaning – My experience
After my recent trip to South Africa, my Konica Minolta Dynax 7D digital SLR camera had a significant problem with dust on the sensor (5 or 6 spots very visible on clear skies or plain surfaces). I decided to go for the Sensor Swabs from Photographic Solutions Inc. All in all, this is a very…

HardwareLogic offers to go much further than the usual defragmentation offered in standard by Microsoft. In a detailled article, they describe the use of Contig (a Microsoft tool with an indigent command-line interface) and Power Defragmenter GUI (a software application that provides exactly the right human-readable interface for the previous one).

1 Tera-pixel!
1000 millions of pixels, that was good enoug. 1000 billions of pixels is better! But it’s really a technical challenge.

Watch TV online for free
