Tiring problem with failed bluetooth reactivation after sleep in osx yosemite

Some of you experience the problem of bluetooth devices which can not reconnect after a sleep period of osx yosemite. This is a known problem a bluetooth kext unload and load solves the problem (like bluetooth subsystem restart) but there is no path from Apple there until now. Some of you have built up some shell scripts and are using sleepwatcher and so on but some of you just want to get it to work again. Therefore I have built up a little application which is just an automator wrapper around the following two shell script lines:

sudo kextunload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport
sudo kextload -b com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport

which does the trick for you. You can fully trust this and you can also look into the package, no hidden hocks there. Drop the application to your app folder and everytime you experience the problem start the app, the bluetooth will go away and come back again reconnecting all your devices. Link to 7zip archive with app. Please download the prior link by right click and download linked file to…

Best Regards.

Multiple application entries in „Open With“ menu

If you get a lot of duplicates in the menu which opens if you open the context menu on a file to say „Open with“ you have to rebuild your launchservices database by issuing a little command line command. Open up the terminal application and paste the whole code from below into the terminal window, press enter and wait until the command returns:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

Afterwards alt + right click (if secondary click activated) or ctrl + alt + click (if secondary click not activated) above the finder icon in your dock and select the restart option. Your „Open with“ menu should now be fine.

This was tested on OSX 10.8.3

Enable Restart X server (Ctrl-Alt-BackSpace) in Ubuntu 11.04 Natty Narwhal

If you have the problem that your ctrl-alt-backspace combination does not work and you have to restart the x-server see this blog entry here for the solution or simply go to System –> Preferences –> Keyboard –> Tab „Layouts“ –> Button „Options“ –> open „Key sequence to kill the X-Server“ and enable the checkbox. Done.

FAST Crawler restart, db timeout and refresh period

We have some people looking at the logs now. There can be several reasons why the akonit.at is missing. Hopefully the logs will provide us with some answers. The hbdWebWeekly collection is configured to start from scratch, with db interval of 3 and refresh cycle of 10 days. From scratch means that each time the crawler is started the work queues are truncated. The db interval will determine how many times the crawler is restarted or refresh cycles elapsed before the URL is deleted (if it is not found by the crawler). This means that if the crawler is stopped and restarted often and the crawler has not gone trough a refresh cycle after 3 restarts some URLs will be deleted. It is therefore recommended that a complete refresh cycle is completed within the db interval. In this case the crawler should be running for 10 days at least for each 3 restart.
