How To Fix Common Java Issues In Windows

So you're sitting there playing your favorite PC game, or compiling the latest version of the Linux kernel, and suddenly you hear your smart phone play the TARDIS ring tone from Doctor Who. You check the caller ID and notice it's that old lady you fixed a computer for recently. You answer, and she immediately starts complaining about how this Java based game on "the Yahoo" doesn't work any more.

Fixing little JRE issues for end-users can be annoying, but if you have a better idea of what to look for, it can save you a lot of time.

Try Mozilla’s Webian Shell

Webian Shell is a full screen web browser (simular to Chrome OS) with a minimal interface, and is very web standard compliant. It's still in a very early stage, but worth checking out if you've been following Chrome OS.

You can download it from Webian.org

To run in Windows and Mac OS, you unzip the file and run the executable.

In Linux, download and run:

tar -zxvf webian_shell_0.1-linux_xx.tar.gz
cd Webian\ Shell/
./Webian\ Shell

 

To install Webian Shell in Ubuntu, so you can run it by just typing webian in the terminal:

tar -zxvf webian_shell_0.1-linux_xx.tar.gz
sudo cp -r Webian\ Shell/ /usr/share
sudo ln -s /usr/share/Webian\ Shell/Webian\ Shell /usr/bin/webian

 

Now you only have to type webian into the terminal to run, regardless of directory. You could also create a launcher that points to /usr/bin/webian.

Downgrade Miro From 4.0 to 3.5

Miro Database Error

 

Miro is a great open source application for managing video podcasts. However, when I upgraded to version 4 I was having issues with the program. So I tried to downgrade it by downloading and installing an old version from here, which resulted in this database error.

Luckily, Miro creates a backup of your database when performing  an update. To get the old version working again, you need to replace the new database file with the old one. If you can still open Miro, go to Help > Diagnostics to view where the database is stored.

If you can't open Miro, use the list below to find the database for your OS.

Windows XP: C:\Documents and Settings\(yourusername)\Application Data\Participatory Culture Foundation\Miro\Support\sqlitedb

Vista/Win7: C:\Users\(yourusername)\AppData\Roaming\Participatory Culture Foundation\Miro\Support\sqlitedb

OS X: /Users/(you)/Library/Application Support/Miro/sqlitedb

Linux: ~yourhome/.miro/sqlitedb

 

In the same folder as the sqlitedb file, there should be a dbbackups folder. Rename and copy the most recent database backup, from the dbbackups folder, to sqlitedb and replace the newer sqlitedb file with the backup. Now you can run the old version of Miro without losing all the feeds and playback info.

If you haven't tried Miro, check it out at getmiro.com

Recover Deleted Files From ClearOS Flexshares

The Accidentally Deleted File

 

By default the recycle bin is enabled on ClearOS shared folders. So don't panic when someone deletes one of your super important files.

Get started by going to the shared folder the file was deleted from. To access the ClearOS recycle bin, you will need to enable "Show hidden files and folders." If you haven't done so already, click Tools at the top of the window. Then click "Folder Options"  select the View tap, then click the radio button next to "Show hidden files and folders." (If you use a Linux desktop, you only have to press Ctrl+h)

Make Backspace Go Back in Firefox for Linux

Over time I've developed a habit of pressing Backspace to go back a page when web browsing, but the Linux version of Firefox doesn't do this by default. You can use Alt+Left Arrow to go back.

Making backspace go back only requires a simple configuration change.

Open up Firefox and type about:config into the address bar.

If you get  the message that says "This might void your warranty!" just click "I'll be careful I promise!"

Type backspace into the filter bar.

Double click the only line that shows up, which should be browser.backspace_action

Change the value from 2 to 0

Click OK and close Firefox. When you re-open Firefox the backspace button will go back a page, like it should.
