Update POLAR Certs

Every 1 to 3 years we are issued new POLAR certificates that need installed on our servers to allow us to connect to HTTPS on our servers. This is a security feature where the servers need to have their target certificates installed.

Use the following attachment [ update-polar-certs ] [ developers-vm-polar-cert-update ] to allow you to copy-n-paste the commands, also this was for the batch server which is on Java 1.6.

Go to halprdjobs02.hq.halw.com and run the following commands as root:
$ cd /usr/java/jdk1.6.0_45/jre/lib/security
$ /usr/java/jdk1.6.0_45/bin/keytool -v -import -trustcacerts -alias pcl_rsa -keystore /usr/java/jdk1.6.0_45/jre/lib/security/cacerts -storepass -file /software/pcl-cert/JBoss/COMODO_RSA_Certification_Authority.CER
$ /usr/java/jdk1.6.0_45/bin/keytool -v -import -trustcacerts -alias RSA-organization -keystore /usr/java/jdk1.6.0_45/jre/lib/security/cacerts -storepass -file /software/pcl-cert/JBoss/New_Princess_COMODO_RSA_Organization_Validation_Secure_Server_CA.cer

Gimp like Photoshop

refer: http://www.omgubuntu.co.uk/2016/08/make-gimp-look-like-photoshop-easy
refer: http://doctormo.deviantart.com/art/Gimp-2-8-Photoshop-Tweaks-432736644

To help a fellow deviant, I've put together a download that anyone with Gimp 2.8 on Linux can use to make their copy of gimp look more like Adobe Photoshop and make people more comfortable.

I've taken various bits of guides online and various tweaks. All you have to do is download the file, unzip it. Then in the file manager go to your home folder, show hidden files, delete or move your old .gimp-2.8 configuration folder out of the way, and replace with the new one. Then load gimp. Then me know if it works for you or if it fails.

See attached file to import
