Over the time, your operating system tends to generate temporary files which get on accumulating in the temporary directories. This negatively affects the system responsiveness & off-course wastes disk space. Further, there are also other resources like browser caches, thumbnail caches & more which if not cleared from time to time make the system sluggish. An advance user may very well take control & go rectifying each of the above problems. However that would mean more time to clear up each individual thing. Here, steps in to rescue is KDE’s very own utility – Sweeper(Application>Utilities>Sweeper).
As the name suggests, Sweeper is a tiny utility which lets one clear all the unwanted clutter from the system. The interface of sweeper is ridiculously idiot-proof & all the options are self explanatory. Simply check whatever you wish to get rid off from your system & hit “Clean Up”. Sweeper is capable of clearing cookies, temporary files, thumbnail cache, browser cache, favicons, clipboard, recently used document list, recent applications etc.
From time to time, I recommend running Sweeper & letting it do its job. It will ensure you good disk resources & a responsive computer.
Often you’ll find some applications not available in your OS repository/third party repository or you need to install a recent version than the one in your repository. Whatever the case might be, you’re left with no option but to compile & install the application from the source tarball provided from the application’s project website. Beginners might feel this process to be intimidating but its not that difficult. Once you repeat it a couple of times, it will become a second nature to you. I’ll outline some basic steps which will help you to install the application from a source tarball.
With the recent Adobe Flash Player update(11.2) in Linux, there seems to be a major color glitch in flash videos for users using Nvidia graphic cards. When viewing flash videos, a user experiences the colors being reversed/altered like you’re watching a negative slide of a film. Imagine, watching a red Ferrari in stark blue & the skin tones of humans being transformed to that of folks from the movie Avatar. Yes, its really frustrating. Updating the Nvidia drivers to the latest won’t work.
To fix this colour glitch, unfortunately one needs to disable hardware acceleration for videos. To disable hardware acceleration, open up a youtube video, right click in the video area & select settings. In the first tab(Display) itself, you should get “Enable Hardware Acceleration” option with a checkmark in the radio box. Simply uncheck this & now try playing a video. If everything goes well, you should be able to view colours accurately.
Another option is to rollback to Adobe Flash 11.1, if you prefer not to disable hardware acceleration. I hope Adobe issues an update on this soon.
Photographers often need to resize hundreds or even thousands of picture from time to time. Manually resizing each photographs one by one will ensure you do not get time to do any other things & missing submission deadlines. The solution to this answer is “Batch Resize”. As the name suggests, it means resizing photos in large quantities in one go. In this article, I’ll show you how to resize photographs in Digikam.
Photo collage make for a wonderful gift. It makes for a good gift since one can include photographs shot across various time-line of a relation which when looked back brings immense satisfaction. Being a photographer, my friends have been receiving such photo collages from me. To make this collage, I use a nifty piece of software known as “FotoWall”.
