Prevent auto screen locking - Java

My first job was at an IT company where they used to have a company policy wherein they lock your PC after every 3 minute. The usual excuse was Information Security. Just imagine, every-time you have to take a leak, the PC would just lock itself up. The situation was exasperated because of another thing, the password policy, which demanded every password to be 

  1. At least 8 character long.
  2. At least one number.
  3. At least one lower-case alphabet and one upper-case alphabet.
  4. and at least one special character.
Now, all thing rules made the remembering of password a bit of a hell and on top of it was the 3 minute locking rule.

That was the time when I decided to do a bit of mischief and code a software which will do the task of moving the mouse, which would effectively prevent the desktop from locking itself. I started to look for things which would enable me to do this.

That's when I encountered Robot, a class Java provides since J2SE 1.3. This class acts like a simulation tool for various UI components ranging from keyboard to mouse.

My tool was ready within a day or so...and I have recently posted the same in Google Codes. 

One can reach the sources here, or can download the jar file here.

Multimaster replication with Symmetric DS

Symmetric DS is an awesome tool for trigger based replication whcih works for all major database vendors, including but not limited to PostgreSQL, MySQL, MSSQL, Oracle and many others. Symmetric-DS is a java application and can execute on any platform on whcih JRE is available including Windows and Linux. Trigger based replication, in constrast to disk based (eg. DRBD ) or transaction log file shipping based or statement based , works by registering triggers on DMLs and sending the data thus generated to remote machines. Another very popular trigger based DB replication tool is Slony . Symmetric-DS in addition to being database agnostic also supports multi-master replication (MMR). MMR usecase involves multiple database nodes, connected in a pool with DML updates coming from any of them. This is different from the normal master-slave replication, where slaves are not expected to generate any data events, and the sole authority of database is the master. MMR requirement causes d...

Reset root password RHEL/Rocky/CentOS 9

Unlike the earlier versions of Rethat variants, version 9 doesn't allow single user mode to change password, as maintanance mode in 9 requires root password .

To reset the root password on the other hand, one requires to follow a specific set of commands, At the boot menu, edit rescue mode to append 'rd.break ' at the end of the line starting with kernel.

Devstack installation with cells in multiple machines

  Devstack is a testing and development package for OpenStack . The official devstack website has excellent but terse installation instructions, which could be daunting to a newbie. Normally, a traditional install is pretty straightforward but problems creep in when you have to go for some particular configuration or installation like cells or a simple code-test-debug setup, the information on the main site is insufficient. In this blog, I will enumerate the steps for setting up a cell-ular devstack installation with one parent and one child. Parent will not be instantiating any VMs s it's only a 'command centre'. 1. On both machines, install git and vim, clone the devstack repo using git. yum install git vim git clone https://git.openstack.org/openstack-dev/devstack 2. On both machines, open up the file 'local.conf' inside the cloned directory 'devstack' cd devstack; vim local.conf 3. Copy the parameters below to the file...
