Ken's Tech Note

The Kindle Fire HD 7" has one of the best screens for enjoying multimedia content and reading. The stock OS did not have much value compared to third party ROMs. I have been using third party ROM and has settled with official CM11 for quite some time (about a year) until last week. xda Forum contributor faZevoLv has released an unofficial OmniROM running on Lollipop 5.1 - which installed smoothly with the latest GApps found. (I tried CM12 beta, too. I installed but it gave a series of FC upon booting up. I believe it might have to do with the version of GApps but did not research further on the correct version). The user interface is very responsive, animation is quick and I have experienced no lag. Make sure you have a second bootloader before installing OmniROM. http://forum.xda-developers.com/kindle-fire-hd/7-development/rom-omnirom-android-5-1-t3052050

Trying a new social network platform for enterprise. Humhub is a new social platform and during installation, it has some compatibility issue with ISPConfig3. The error was related to open_basedir - open_basedir restriction in effect. The discussion can be found at https://github.com/humhub/humhub/issues/129 Proposed solution: apt-get install zendframework-bin mkdir /usr/share/pear Then under ISPConfig3: ISPConfig -> Sites - > Select relevant site hosting humhub -> Options Under PHP open_basedir, add ":/usr/share/pear" Restart apache2 for the settings to become effective. Installation is successful.

I had more than once performed upgrade to 10.04LTS and after the classic apt-get update/upgrade, the cloud server refuses to boot up correctly. That's why a daily backup (if not more frequent) is very important. A lot of times after apt-get update/upgrade a full reboot is not necessary as the services may restart themselves. That's why it is hard to tell exactly which system update might have caused the problem. Rackspace Support Network / Community has a good article to diagnose the root cause and provide a solution that has fixed my issue. https://community.rackspace.com/products/f/25/t/999 In essence, the grub configuration may have been messed up so a reconfiguriton of Grub is required. To do this, we would need to put the server in Rescue Mode. It is like putting a server in single user mode but with network access (so you can still manage it from remote). Be sure to go through the high quality comments underneath the original post for additional troubleshooting...

Situation: An old Ubuntu 10.04LTS server running on Rackspace First Generation Server Running ISPConfig 3 as the main control panel Wanted to upgrade to latest LTS as 10.04LTS support ends in April 2015. Steps: 1. Backup using Image under RS mycloud control panel for recovery. 2. Get into SSH 3. apt-get install update-manager-core 4. apt-get update / apt-get upgrade - to update all packages 5. remove the sites-enabled in apache2 configurations (as apache 2.2 to 2.4 has some changes) /etc/apache2/sites-enabled/ 6. do-release-upgrade -d - this updates system from 10.04LTS to 12.04LTS - download was about 250M 7. setting a new MySQL password during the update / allow services to restart / other prompts: choose default values (i.e. keeping existing version of preferences, rather than using distro's default). Giving a new MySQL somehow reduced a lot of intermediate prompts for MySQL password settings. 8. at the end of upgrade, it prompts for deleting old packages (I chose...

Google has released Lollipop 5.0.1 shortly after 5.0 release. By following the instructions from Google, it is easy to flash LP5.0.1 https://developers.google.com/android/nexus/images As usual, the first boot would take a few minutes, so be patient. Very happy with a 2-year old tablet that is capable of running the latest Android platform.

Following the post from Digital Ocean to get started, under a Ubuntu 14.04LTS installation with latest updates and patches through apt-get update/upgrade https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-a-basic-ldap-server-on-an-ubuntu-12-04-vps But during the creation of "Generic: User Account", the password field has shown an error.
