Virtualbox: VT-X is not available

Thursday, October 3, 2013 - posted by CSch

In some cases when you try to get a virtual machine running with Virtualbox or similar virtualization software you will get an error stating that 'VT-X is not available'. This relates to BIOS settings which, depending on your processor, determine whether your computer is able to virtualize stuff. These settings are not set automatically however, so it's worth a look into your BIOS whether you can actually change the setting and if your processor allows it.

The keyword to look for in the settings is 'Virtualization', it's probably placed in some advanced tab if there are some of those in your BIOS.

Dovecot is watching the whole server filesystem for modifications and removed or added sub filesystems. If you get errors similar to this one on your server:

Aug 30 09:10:23 server1 dovecot: master: Warning: /var/www/clients/client1/web1/log is no longer mounted. If this is intentional, remove it with doveadm mount

 (the directory path may vary), then you can fix it by excluding the path from being watched by dovecot. In my case, dovecot shall not watch my website directories as they do not contain any mailboxes

Run the following command on the shell as root user:

doveadm mount add '/var/www/*' ignore

To exclude all files and folders in /var/www from deovecot monitoring.

 

Disable Opera mouse gestures

Friday, August 23, 2013 - posted by CSch

The Opera browser uses mouse gestures that allow the user to navigate through tabs and tab histories with the help of mouse-clicks and -movements. This can be a hindrance however if you are used to control the browser with its own graphical interface and often just play around with your mouse out of boredom.

To disable these gestures you simply need to open an Opera window and go to Settings > Preferences > Advanced > Shortcuts and uncheck the Enable mouse gestures checkbox.

How to change Windows 7’s default fonts

Monday, August 19, 2013 - posted by CSch

Windows 7 has hidden away some features and options pretty neatly but nonetheless they still exist. Such as the option to change the system fonts. To get there try searching for Change window colors and metrics in the Start menu (metrics is also sufficient).

Hit enter if you have found it and you will be guided right to the fonts window where you can change the font and size of all the Windows fonts. And since we all love Comic Sans, why not use that on every option?

How to disable network file-sharing on Windows

Thursday, August 15, 2013 - posted by CSch

If you want to turn this feature off at all or partly you can do so through the Control Panel. Open it from the Start menu and head to Control Panel > Network and InternetNetwork and Sharing CenterChange advanced sharing settings.

Here you find two drop-down-menus where you can decide over public- as well as home-network specifics:

Reveal hidden files and folders in Windows

Tuesday, August 13, 2013 - posted by CSch

Windows hides certain files and folders by default to prevent the unexperienced users from messing with them.  In some situations however it is necessary to view them, e.g. to backup some data from the hidden App Data folder.

So to make hidden files visible, open the Control Center and head to Appearance and PersonalizationFolder Options. Open the View tab and under Advanced Settings check the Show hidden files, folders and drives checkbox. Confirm with Apply or OK and every hidden file and folder will be visible as transparent item in the explorer from now on.

View a list of all shared folders on Windows

Thursday, August 8, 2013 - posted by CSch

With preferences you make concerning single files and folders it's easy to lose track of which files you have currently set as whatever you needed them to be. This is especially important for shared files and folders since you don't always want them to be shared with everyone.

Good thing there is a list with all shared files hidden on your system - to get to it search for Computer Management in the Start menu.

On the left pane of the CM window, browse for Computer Management (Local)System ToolsShared FoldersShared:

10

You'll get a list of items here that are shared by your computer with path and description given.

Disable “Check for solutions” dialog in Windows

Friday, August 2, 2013 - posted by CSch

When something crashes on Windows you will often see a dialog showing that Windows is checking for a solution of the problems. Frankly, Windows has never found a solution for my crashes itself and it made more sense to abort the search and go for it myself.

If you are feeling the same way you might want to turn the dialog off completely. To do that, left click the little flag icon on your task-bar once:

Select Open Action Center and head to Change Action Center settings on the left side pane, then scroll down and click Problem reporting settings where you have the option to select Never check for solutions. Confirm with OK and you should be good to go.
