On a computer when right clicked on the desktop one was getting the alert saying that "Windows Explorer stopped working.Trying to find solutions.." etc. I first tried to do "sfc /scannow" on a root command prompt which gave that everything is OK. Then I started investigating the cause of Windows Explorer's crash by navigating through Event Viewer. And I found entries which clued that explorer.exe's crash is due to shell extensions dll file. Then I realised that there is a good shell extensions viewer provided free by Nirsoft at http://www.nirsoft.net/utils/shexview.html. Thanks to these guys I used the program and found the third party extension which I guess infected by a malicious program. First disabled it and checked that if it causes the crash, then removed the Registry keys of it. Voila now the explorer.exe is working just fine.  

Yes thats true and awesome. You can edit pdf files (with some restrictions) on openoffice.org 3.0+. You must install the oracle-pdfimport extension. Nice work!

Ok trying to configure a windows xp guest on this server, I did the directions on the manual at virtualbox.org. I used VBoxHeadless which is great for a server environment. Previously I tried virtual OSE provided by Ubuntu repos whose version is 3.2.8 at the time.But it seemed that OSE doesnt support vrdp although here is a post claiming otherwise http://forums.freebsd.org/showthread.php?t=13499. Then I decided to install closed source edition from the provider according to this post http://www.howtoforge.com/vboxheadless-running-virtual-machines-with-virtualbox-4.0-on-a-headless-ubuntu-10.10-server.Everything worked fine and I installed the guest host. Then I noticed that there are two mouse pointers and the resolution is not adjustable. Then after some work I reinvented (remembered) that one must need to install guest additions thing too. After installing it now the machine working nice.

These days I am tackling with Django on a centos server. I installed django package downloaded from its site.Started a simple app. Now trying to use database mysql. When it ocmes to mysql I needed to install some packages like mysql-devel,python-devel and most importantly MySQL-python (notice the capital letters). An older version of this is in centos stable repos.After some search I learned I can install it in different ways like compiling or using test repo.I chose the former and installed python-setuptools. And then I realised that there is easy_install in this package which helps me installing the required MySQL-python package. And voila.

JQuery is a nice library with whom I havent played till yesterday. Since yesterday I am struggling with this nice library, actually not solely with it but with validation plugin. That plugin is nice too but when it comes to integrating it with another plugin which you guess Masked Input, I was having problems. Because my form is dinamic and I am adding elements whose names are the as previous ones, I have struggled a lot. But at the end I did what I wanted to do. This jQuery.validator.addMethod("acceptreg", function(value, element, param) {   return value.match(new RegExp("^" + param + "$")); }); small code piece helped me a lot when validating text and phone fields and their integration with Masked Input. I know validation plugin normally does validate against phone but my case was different. I declared such a method as described above and used it inside with tel: { required: true, minlength:11, maxlength:11,acceptreg: "[0-9]{3}-[0-9]{7}" }, I d...

On a centos 5.5 64 bit server I was getting mcelog errors from cron.hourly/mcelog.cron stating "/etc/cron.hourly/mcelog.cron: mcelog: warning: record length longer than expected. Consider update" As a workaround I did add 2>&1 to the last line of /etc/cron.hourly/mcelog.cron file as mentioned in Known Issues in this page http://elrepo.org/tiki/kernel-ml    

On a centos 5.5 server I was getting sendmail errors which I didnt want to try to solve. Then I installed postfix as an alternative and it does the job now.
