Ubuntu 11.04

I didn't touch Ubuntu until I have to upgrade about 2 major versions.  Actually I was forced to upgrade because the old one wasn't supported any more.  I kept updating by default until it was 10.04, and no more.  I was happy that nothing broke.  There was but you can fix it somehow or leave it alone.

Now when I was totally enjoying it, especially the gnome applets, I saw the new 11.04.  I tried to upgrade and find out that I have to upgrade to 10.1x first.  You have to push a button instead of by default.

After two major upgrades and fixed some broken stuff, only to find out that gnome applets are history.  So what worked on my last goodies post won't work at all, or looks differently.

I like the new Unity 3D GUI.  It's space saving.  In MS Windows terms, the whole status bar integrates with the quick launch area, and it's auto hide.  Also title bar of applications integrate with the menu bar.  So it's back to Windows, you have only one bar normally visible.  Also the scroll bar becomes hair lines when you are not using it. 

There are themes and 3D effects but I'm not up there yet.

I switched back to the Ubuntu Classic GUI.  You can do it when you login.

Ubuntu goodies

My wireless router and firewall broke.  Before reinforcement arrives, I found a soft firewall - Firestarter.  It's better than anything else, including a hardware box.

Linux has a pretty good firewall built in.  All you need is a easy to use GUI.  A resident firewall manager is easier to use than any separate firewall box.  Firestarter understands the software that needs external connections such as Openvpn and Tor.  If you install those from the package managers, it's likely Firestarter understands it.

Being resident, Firestarter notifies you when an attempted attack occurs, which is frequent if you surf the net unprotected.  Attack means attempt to connect to your machine.

You can be paranoid enough to allow selected applications to use the internet.  It can be like Zone Alarm if you like to.

More useful to me is not the firewall functions.  You can see active connections.  I can see what traffic is routed through my VPN, my proxies, or chained.  It is simple enough that I can actually make good sense of it in real time.

The bad thing is that your external IP is stored on your computer.  Spyware can just read it.  But still they have to get external connection to report the IP.  If they get an external connection, in theory they can bypass your proxies and VPNs to get your real external IP.  It's not likely though.

The other goodie is the Windows equivalent of the task bar, as shown.  You can almost install or drop anything into it, plus select almost any picture for your icon.

Your can have your own script, add an icon to it, and put it on the task bar.  Firstly it's so simple that you can have two versions of everything.  When your fingers are on the keyboard, the need to pick up the mouse is greatly reduced.  When your hand is on the mouse, the need to bring up the terminal is also greatly reduced.  You can have one task bar to as many as you want.

A month without booting into Windows.  When it's cool to use Google Docs, there's no need to.  Google Docs is better with auto save and auto version control.  The version control in Words is laughable, and therefore you probably never heard of it.
