These are my installation notes from installing Cyanogenmod 13 on Samsung Galaxy S4. This S4 was originally brought from T-Mobile and its model number is SGH-M919. The Cyanogenmod codename for this device is jfltetmo. Prior to following my notes, read through the CM wiki at https://wiki.cyanogenmod.org/w/Jfltetmo_Info
1. Install JDK and Android SDK for adb
2. Install heimdall. However the classic one doesn't install. Had to use Heimdall-1.4.1-Unofficial-Signed.dmg
3. Go into Download Mode (Vol Down + Power + Home Key) with no wires connected....

After booting from the external drive (Fedora 17 Live), I mounted the ISO file in loopback mode
[root@localhost home]# mkdir /tmp/livecd
[root@localhost home]# mount -o loop /run/media/liveuser/WINDOWS/Fedora-17-i686-Live-Desktop.iso /tmp/livecd
[root@localhost home]# cd /tmp/livecd/LiveOS/
Next make sure that you have an empty SD Card at '/dev/mmcblk0'. Erase the head if need be and recreate the partition table.
## Destroys partition table and MBR
[root@localhost LiveOS]# dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=100

One of our clients host a content management system built on top of technology I use at work. The technology is a custom server that stacks on top of the J2EE application servers like JBoss or a servlet container like Apache Tomcat. Our standard stack that we prescribe to clients is the MySQL-Apache Tomcat stack. Over a period of few weeks, the needs of this client grew well beyond the standard stack. Considering the amount of static content being...

Mantis is one of the many bug tracking softwares available out there (Refer: Top Configuration Management). For an internal project at work, I needed a bug tracker and Mantis was the logical choice due to prior experience within the development team. The machine at hand was running on CentOS Release 4.4 and required the following rpm packages:
[root@eclipse html]# rpm -q httpd mysql-server php php-mysql php-ldap
httpd-2.0.52-28.ent.centos4
mysql-server-4.1.20-1.RHEL4.1
php-4.3.9-3.22.9
php-mysql-4.3.9-3.22.9
php-ldap-4.3.9-3.22.9

While setting up Apache HTTP Server to rotate logs I came across an interesting problem. How would you truncate a file? The trivial solution that I came up with was[root@lambda ~]# rm -f /var/log/httpd/foo.log[root@lambda ~]# touch /var/log/httpd/foo.logUnfortunately this doesn't work. The HTTP Server ceases logging to the file unless there is a server restart. After prying around the web I came across some interesting tricks but the one that stood out was:[root@lambda ~]# :> /var/log/httpd/foo....
