Searching for tool bar actions in Juno shows that user should be able to unlock tool bar for customization. Unfortunately this function is not working, see bug 340695 . If you really wanted to move the icons there is a workaround. Change the theme to Windows 7 and restart. You should now be able to move items around.

Eclipse 3.x series performed pretty good enough that I use it for XML and Python editing. But the latest Eclipse 4.2 Juno release is pretty slow on virtual machines. Few minor tweaks made it bearable for me. Open Preferences dialog ( Window | Preferences ). Expand to General | Appearance , then change Theme to Classic and disable Enable animations . Preferences - Theme to Classic

Microsoft has been trying to copy Apple's strategy of designing there own hardware and software combination. This works pretty good in Apple's walled garden for long while but they did get bitten by their maps disaster (see  https://www.google.com/search?q=apple+maps+disaster ). For Microsoft's case, Mozilla and Google are not in a hurry to support the Modern UI. In fact they probably are not going to write one as Win RT is restrictive on what apps can do. Now in relation to browsers, I been using Microsoft Surface for more than a month and lately some of the websites stopped to work or display data properly. In Android land, I have many choices. I used Dolphin Browser, the default Android browser, Google Chrome, and Firefox, I can switch as the need arises. With Surface, no other option. I am using my Surface now because I wanna immerse with the platform otherwise my TF101 Transformer still rocks.

I have been trying to get immersed with Windows 8 lately. The more I use the modern UI on a non-touch interface the more I don't like it. There is just too much impedance between using mouse/keyboard for an interface designed for touch input. Anyway, I read somewhere that the Modern UI interface supports splitting applications. I took me a while to learn that for it to work you have to have at least 1366x768 screen resolution. This is maddening..... argh. First, I couldn't open apps on screen resolutions below 1024x768. Now splitting needs higher resolution. Microsoft looks like is in identity crisis as of late. They don't just get what user needs. Or maybe people involved in the project do understand but management have a different agenda. Good luck Microsoft, you guys will be in for a difficult time against competition.

So I installed Windows 8 in VirtualBox, the host machine is laptop with 1280x800 screen resolution. Running a guest not in full screen only have 1280x736 real state. In this configuration, I am not able to run Modern IU (Metro) apps. See below for the error message. Not able to run "Store" app It seems like Windows 8 requires at least 1024x768 to work with the modern applications. This is interesting because they are making fun of original Android tablets as not flexible, like you know running weird screen resolution. The layout capabilities of WPF applications is suppose to be flexible, what's going on Microsoft! So this also means that netbooks with smaller screen will not work properly with Windows 8.

When cloning a Ubuntu guest machine, you need to take care of few details to make it work properly. Below are the key items to change: Update /etc/hostname , change it to the new machine name Update /etc/hosts , change one of the loopback name to the new machine name. Modify /etc/udev/rules.d/70-persistent-net.rules so that eth0 (generally) points to the updated MAC address of the virtual machine.

To change Ubuntu(Debian/Mint) machine hostname, edit /etc/hostname . You may have to reboot machine for the changes to take effect. Note that for the new name to resolve locally, you need to edit /etc/hosts . The line that contains 127.0.0.1 below localhost should match with the hostname.

To list installed packages on a Ubuntu (Debian/Mint) system, do: $: dpkg -l

To change group ownership of ~/tmp and folders and files below it to say www-authors do: $: sudo chgrp www-authors ~/tmp -R

Below adds a group called www-authors $: sudo addgroup www-authors Reference(s): Manpage

So you have a Debian based installation (i.e., Ubuntu, Linux Mint and of course Debian itself), how would you know if you need to reboot after running apt-get upgrade ? Well, this should be as easy as checking for the presence of the file /var/run/reboot-required Tags: apt, apt-get, upgrade, reboot, required References: http://askubuntu.com/questions/28530/how-can-i-tell-what-package-requires-a-reboot-of-my-system http://serverfault.com/questions/92932/how-does-ubuntu-keep-track-of-the-system-restart-required-flag-in-motd
