Cleaning a camera CCD with a vacuum cleaner and a Lens Pen

I had Fuji S1, S2 & S3, all of which had dust magnets for sensors! They would get dirty even if I did not remove the lenses, simply from the air that got sucked in by varying the focal length of the lens. However, I cleaned them quite successfully with a vacuum cleaner. However there…

Using VirtualBox to run Windows apps that will not run on WINE

I’m a big fan of WINE and an even bigger fan of CrossoverLinux. This is the commercial implementation of WINE by CodeWeavers. For many Windows apps it works very well indeed. In many ways I prefer it to using a virtual machine (VM) because firstly one does not have to start a VM just to…

How do I stop Google indexing a particular page on my site?

There are several ways to stop Google and most other search engines indexing a page. The simplest is to use a “noindex” metatag on any pages you don’t want indexed. Here’s the HTML code, in context.

But for routine backup, I look for reliability, low cost, ease of use, high-speed, high capacity and redundancy – so I am not reliant on just one device.

Sometimes in GNU/Linux one needs to set file and directory permissions separately and recursively. This is a way to do it. Set file permissions:- find . -type f -print0 | xargs -0 chmod 644 ; Set directory permissions- find . -type d -exec chmod 755 \{\} \; Note these are powerful commands with which you…
