One of my friends had a problem with his HP Slate 7
My HP slate 7 will not charge nor will it turn on, I have tried a different charger and different outlet plug. I tried different cables and different PC ports. Looks like the battery is not working anymore.
And true he is. The battery was discharged way bellow the operational limit. The HP Slate 7 has a Li-Polymer Battery: 3.7V, 3500mAh. Usually this type of batteries are charged up to 4.2V (Charging cut-off voltage) and work down to 2.75V (discharge cut-off voltage). Read More

Yesterday I had to move some files from my computer to a public computer (printer center) using my personal usb memory. After I came back home I inserted back the USB and it was no surprise for me to see a strange behavior.
As a general info … All public computers are infected with all kinds of viruses and computer worms. Read More
I recently got into trouble trying to scan around 50 pages using my home scanner. I use a HP Officejet 4500 that have an automatically feed scanner that is able to scan one sided documents. Unfortunately, all my pages were double-sided.
At first I tried to manually scan page by page but I abandoned this action very quickly while 50 double-sided pages require a lot of time and effort. So I had to search for better solution… Read More
I am using a Raspberry Pi in a museum with an information intranet site loaded. We have two Pis with the same details. From time to time we need to update the site with new exhibits/information. I create the SD cards for the Pi using disk imaging from a master that I keep at home. The problem is that each time I update the site the size of the disk image roughly doubles (started at about 2Gb, now at 15Gb). I am using Raspbian GNU/Linux 7. I have deleted the contents of the trash folder. Any ideas as to how I can reduce the size of the created images?
Ever wonder if you can watch 3D movies on your normal display? Or what technology is behind this?
Well, than basic idea of 3D images is that each of your eyes must see a slightly different image. The technique for creating the illusion of depth in a image is very old and is called Stereoscopy.
Stereoscopy creates the illusion of three-dimensional depth from given two-dimensional images. Human vision, including the perception of depth, is a complex process which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make intelligent and meaningful sense of the raw information provided. One of the very important visual functions that occur within the brain as it interprets what the eyes see is that of assessing the relative distances of various objects from the viewer, and the depth dimension of those same perceived objects.
