Trying to run Microsoft's Development Version of Windows 8 you might run into some problems - the two major ones being these two:
What Windows Version shall I choose in the construction of the machine?
The solution here is to choose the appropriate version of Windows 7. If you downloaded the 32 bit edition, choose Windows 7 32 bit, same for 64 bit.
When I start the machine I get some error!
Starting the machine for the first time you will most likely get the error stating:
"Windows failed to start. A recent hardware or software change might be the cause."
Info: An unexpected error has occured.
This is what you are shown:
To fix this, stop the machine and enter its settings. Go to Settings > System and check Enable IO APIC:
Exit the settings and start the machine again. You should now be able to configure the installation.
You might see the error:
postfix/master: fatal: 0.0.0.0:smtps: Servname not supported for ai_socktype
On a OpenSuSE server when you enable smtps in postfix master.cf file. The reason for the error is that the definition of the smtps port in /etc/services is missing.
Edit the /etc/services file
and add the following lines:
smtps 465/tcp # Secure SMTP
smtps 465/udp # Secure SMTP
Then restart postfix
The way to add new icons and cursors is simple yet not really obvious in Linux Mint. To add new cursors, download any from a webside that provides these (as this), and drag and drop the package file onto the theme preferences of your Control Center:
To add new icons, just download and extract them into /usr/share/icons as root. Afterwards they are available in the Appearance section of the Control Center.
There is a large variety of Firefox plugins currently out on the market but only a small part of them is really useful for the casual internet user, that is why I tried some of them out and filtered the most effective and handy.
Tab Mix Plus
Tab Mix Plus is a great plugin that adds a large variety of functions when dealing with tabs. It can duplicate tabs, pin them to the tab bar in icon size, make tabs unclosable, undo the closing of tabs and reload them every once in a specified interval, which is incredibly useful if you want to watch videos on the internet multiple times.
Answers is a plugin that quickly provides you with definitions of whatever word you need a definition of. Simply click on an expression with the predefined key combination (Ctrl+Click on Linux, Alt+Click on Windows) and a notice will pop up that shows you one or more possible definitions:
All-in-One Sidebar provides you with a flexible, slim sidebar that gives you quick access to your bookmarks, history, downloads, plugins and website and browser information. It also causes the Downloads window not to pop up but to open inside the sidebar on the same window.
To encrypt folders on Linux Ubuntu there is a simple program called Cryptkeeper which, while active, lets you mount and dismount password protected folders.
While unmounted, the encrypted folders are invisible to the user. While mounted, you need to enter the password to access its contents. To create a new encrypted folder just click on the key icon on the system panel and select New encrypted folder.
Make sure to unmount the encrypted folders before you quit Cryptkeeper since the files become accessible if they are mounted and Cryptkeeper is inactive. The files remain invisible if they are unmounted and Cryptkeeper is quit.
To be able to copy and paste multiple entries with Control + C and Control + V there is an applet for the GNOME desktop panel called Glipper which is a clipboard manager and is available in the default Ubuntu repositories. If it does not show up in your list of applets after installation, restart your system and it should be available. Its menu is accessible over the panel icon and the key combination which is configured in the Preferences menu (Ctrl+Alt+C by default). The top entry is the one that will be pasted on Ctrl+V. To change it, just select another one.
In Preferences, you can also configure on what actions selections should be copied into the clipboard, if they should be remembered on system restart and how many entries should be remembered.
There is a desktop panel applet for Ubuntu Linux and its derivatives that is able to store files and folders within a dropdown window accessible from a tiny icon on the panel bar called Topshelf. It is available in the default Ubuntu repositories.
It receives content by just dragging and dropping it into its window which opens upon clicking the topshelf icon. This way you do not have to browse long ways through the file system to find the files you are working on regularly but have easy access on them by quicklinking.
If you are tired of browsing through your files or the menu to find and open an application you do not use regularly or if you just want to speed up the process of opening a program, there is an application for the Gnome Desktop called GNOME Do which you might like.
Install it as usual with your package manager and start it. To call the execution bar, press SUPER (Windows Key on Windows keyboards) + Space and enter the name or parts of the name of any application, script or executable.
If it is not the desired app that is proposed, you can browse the other possibilties with the Up- and Down- keys. To cancel the bar, hit ESC and to execute the displayed program hit Enter.
The default application is the one you open a file with on doubleclick. In some cases installed programs automatically turn themselves into the default application for files you were happy with, which you might want to change. To do that, rightclick a file of the chosen format and choose Open With... -> Other Application or Open With Other Application:
On the window that opens, choose an application or command and check the Remember this application for "..." files checkbox to apply your selection for all files of the same format:
Hit Open afterwards.
After crashing your system and getting entertaining colored screens on boot, you may have to consider booting in live mode from a bootable device such as an installation DVD or a USB-device. However you'll need to be able to log in as root in most cases to make changes in configuration files and others to get your system running again. While you can log in as root with a password on your normal system, you can do so in live mode by entering
sudo su -
into the terminal. This logs you in as root so you get to edit your important broken files to be able to boot from your hard drive again.
