Deleting a directory with data capture
Well, maybe this is a very silly tip to some, one of those things you already know, but how much help these little things or tricks when it comes to managing a system, no?
This is for the command line, and it is a very common problem and remove a directory or folder (for those of Windoze) that is not empty. who not encountered when writing the following line commands?
# rmdir
directory rmdir: directory /: The directory is not empty
this obviously because we want to delete the directory contains data.
good order for it to disappear from the map is # rm-rf directory ready
not see it again, that if if they have the necessary permits clear. Greetings

creating desktop video
Well let the steaks ...
With the need to create a series of demos and some tutorials came the idea to put together some videos with audio containing the screen capture and voice-over operator. Quickly
to search Google the experiences of others could see that the best option (or at least convinced me) was recordmydesktop
, then I started to install.
comes in its command line version and for those who do not like there is a GUI that gtk-recordMyDesktop lama.
How to do well .. is simple:
# sudo apt-get install recordmydesktop
and if you want the graphical version, I recommend it because it is very intuitive and less hard for the plaintiffs and for practical as well.
# sudo apt-get install gtk-recordmydesktop
# recordmydesktop
it starts capturing the output in the terminal will be something like # recordmydesktop

if you want to run from the GUI in Kubuntu option will be in the Multimedia / gtk-recordMyDesktop
The truth may be much more extensive but there are thousands of tutorials out there on how to use this program and it is certainly and other intuitive, so I'm going to the heart takes to write this post ... Well everything worked perfectly when installed on a computer that was new and had installed Kubuntu 8.04 LTS a few days ago, we recorded a few videos and everyone was happy with the results.
Try to do the same on my Sony Vaio laptop that I have also installed Kubuntu 8.04 LTS but this poor recontra is being updated and upgraded from version 6.0 and for those things in life there is a library that is not equal and happened to me is that running recordmydesktop after a few seconds the program remained frozen, sleeping without activity. recontra Search and search the network until I found a bug related to this issue is the
Bug 244261
apparently would be in the
libx11-6, probe to reinstall and nothing so we do not wear out.
I got to try different options and I realized that this guy freak by any of the stationery of X, then I started to try the different options on the command line ... et voila! him out ...
by using the - full-shots and no problems.
then using
# recordmydesktop - full-shots
or graphic in Advanced mode, "whole in every picture captures" = Enabled it's going to work.
For more technical, apparently the problem occurs between libraries and libX11.so.6 libxcb-xlib.so.0, this is some sort of error when recording only video clips that have changed, that is why the modifier - full-shots that it does is copy the entire screen without seeing what has changed makes no error occurs. And for those who worry that it would occupy more space on the end result or would a larger file, then do not stress because when you encode the video, ignore the repeated parts like when files are compressed.
this is the error that pulls ...

other way is through the package manager, in my case Adept 
once installed we can go to a console and use # recordmydesktop
it starts capturing the output in the terminal will be something like # recordmydesktop

When Do Ohio Bucks Drop There Antlers
Well long wanted to do this to document my adventures with Linux, I must say that for several winters ago and I do not use Windoze, and I also say I am very happy with it.
As personal experience I can say that when I was a type of system, having been immersed in computers since he was 12 until today that I have 33, having gone through several PC operating systems and played by ear in many mainframes, today it is inevitable that uses an OS like Linux.
As started in the 80's and my old PC intel 8088 I started programming with BASIC and then go to C routines to create thousands of Assembler, and all those things we wanted to investigate when we started programming, we wanted to say because I do not see someone interested in those things at the beginning, but I think that time is history ...
now fully dedicated to providing services related to the same systems that I developed all my servers and my PC are Linux machines, no matter they do have the OS on the penguin because he has shown no breaks so easy and I can trust him, not only by conviction but by pure demonstration to be working on computers that do not go never, never hang and do not bother me ever, but sometimes be too vague ground and did not do the maintenance and deserved poor or complain, still strong and on track. in this blog I hope to leave my experiences so that others can take advantage of them or I criticize them or what they like, many blogs like this have taken me much help, I hope to contribute my bit.
Exitos!
