Testing websites in Internet Explorer for Windows, using Mac or Linux with VirtualBox

If you develop your website applications from a Linux of a Mac platform, you will have problems to test your websites in Internet Explorer.

Thanks to Microsoft initiative www.modern.ie, it is possible to download a Virtual machine for VMWareParallels or VirtualBox for free, with various versions of Internet Explorer preinstalled. This is a official Microsoft site for all information related to testing IE, great for developers.

Direct download of virtual machines: http://www.modern.ie/en-us/virtualization-tools#downloads

Your problems with Internet Explorer will be easier to tackle if you start testing the browser with this virtual machines.

Thank you Microsoft for helping the community to build IE compatible websites.

mysql does not start and parallels is not working

I just experienced a major server breakdown in 1and1. MySQL crashed and when I tried to restart it the result would be negative:

 

Then I restarted the server and the problem persisted.

So my third action was to have a look at my Parallels Plesk web panel, and the result was that it would not load, showing a MySQL problem.

I then figured out that the problem could be a lack of memory, so I entered with ssh to the server and started listing directory sizes, using the great “du” linux command:

du -h –max-depth=1

until i found that the problem was in the backups folder:

/var/lib/psa/dumps

then I deleted one of the backup folders and could restart mysql

service mysqld restart

Thanks to this guide for the du parameters: http://www.linfo.org/du.html
