Webcam security and “motion detect” with Linux

Set up a Security Webcam with “motion detect” using linux, in contrast to other solutions, is a procedure quite simple, despite the lack of a GUI for the configurations (often it is good not to have a GUI). On the front “hardware” everything we need is a webcam USB, regarding the software we will need a Linux distribution and the program “motion” (in the official repositories). Below I translate and I simplify the procedure comes from the blog Chriswpage.com. (more…)

Photography: remote shutter release with gPhoto2

In today's tutorial we see some small function gPhoto2, a program command-line oriented * NIX systems which in addition to other functions, allows us to access some of the functionality “hidden” (or non-advertised) of our cameras.

It should be stated at the outset that not all cameras are supported. The complete list is available on the manuale online Application.

The operation is very simple. Configure the camera (io face you Canon EOS 20d) so that the USB connection is of type PTP (under the menu “Communication” – “PTP”). (more…)

Enable a swap on any external drive connected (USB also)

In today's article we deal with computer and speed. Consequence of the granting of Windows 7 I became aware of a new, small utility: ReadyBoost. In practice is nothing more than a swap USB drive: enter the key, enable ReadyBoost on the stick, disappears from the key resources and is used for storage of temporary files (not all, some files targeted).

Perhaps not everyone knows that enable a swap USB is not recommended due to (maybe three) main reasons: (more…)

Linux also has a children's applications “portable”, but it is necessary?

For some years now the “portable software” the “x-software” is an established, software che no need to install, but starts directly through an executable. These software were written natively for “turn” below Windows, given the low share of dependencies, and in fact has been appreciated by most of these users on the network, not to mention the praise some of the main newspapers IT online.

What's this substantially? In short, the “portable software” the “x-software” software is often open source, packed, including all dependencies necessary for the operation which goes simply launched and does not require installation. In a few words could be sufficient within the computer a root directory containing links the software is not portable to “soil” the Windows registry, preventing possible malfunction. They are also designed for use by removable devices, come on cd USB flash drives. Simply have the program unpacked the stick. (more…)
