Fix for java.awt.AWTError: Assistive Technology not found


I have found this "weird" error on one of the Windows 7 64-bit machine. After hours of "googling" it comes that the common cause is missing or invalid Java Access Bridge library.

It needs to be manually installed:

1. Download from oracle:

2. Follow the instructions on official docs:

3. Set the system environment variable to point to the related JAB files:

For example:

ORACLE_OEM_CLASSPATH=C:\Program Files\Java\jdk\jre\lib\jaccess.jar;C:\Program Files\Java\jdk\jre\lib\access-bridge.jar

Hope thats helpful :)

Flash Player debugger for Linux x64


In order to use flash in the debug mode you will need the flash player debugger version. Unfortunately there is no support for Linux 64 bit version :/

There is a workaround which kind of works :)

Follow the steps below:

  • Download the 32 bit version of flash debugger:

  • Unzip it and replace current plugin (if exists):
sudo cp /usr/lib/mozilla/plugins/ (Firefox)

  • Install nspluginwrapper
It may be easy as 'sudo apt get install nspluginwrapper' or much more tricky - you may need to resolve all required dependencies).

  • Use the nspluginwrapper to "wrap" the 32 libriary:
sudo nspluginwrapper -i/usr/lib/mozilla/plugins/

  • Check your flash player version:

If all OK you should see 'debugger' version.

Have fun :)

QuakeNet: How to request Q bot?


If you like being on IRC then you may also want to have your own channel. If so it is worth to have always someone there. This "person" can actually be a bot named Q. This post will cover requesting Q on server.

First step is to register yourself on QuakeNet:
/msg Q HELLO youremail@address youremail@address

You should get your password on the given e-mail address. Then you can authorize:
/msg AUTH username password

It is also good to change your generated password:
/msg NEWPASS oldpassword newpassword newpassword

Next you will just need to join an empty channel so you will have OP status there. Then please invite at least three other users to your channel so including yourself channel should have at least 4 people. You should not give them operator status at that point.

You can start to request Q every 15-20 minutes:
/msg R REQUESTBOT #channel
/msg Q REQUESTBOT #channel

Make sure users are still there but at least noone needs to talk :)

It may take from up to few hours to finally get that BOT.

Once everything is OK, Q will finally send you "congratulation" message and he should join your channel.

When you got it make sure your channel is "alive" which means do not leave it empty for too long time. Otherwise Q will get bored and he will just leave the channel :)


XUbuntu: missing title bars and footers

Hi there,

Recently I have noticed problem with missing title bars and footers after login to the XFCE desktop.

To investigate the real cause you can check for you session errors logged in the file .xsession-errors in your home directory.

For workaround there are some simple steps you can do:

1. ALT+F2 and run:  

xfwm4 --display=:0.0 --replace

This should revert your bars but may not resolve the problem permanently but you can always try to add it as default startup command.

2. remove cached sessions folder:

rm -fr ~/.cache/sessions

That's it for now.
