Surprisingly by default JBoss EAP (at least version 5) comes with HTTPS disabled. Here is how to enable it:

May 17, 2013 FPV Japan / BEVRC Cable pinout

If you don’t hear about it FPV Japan is a small device that records standard definition video from analog sources. This is an indispensable device for FPV RC pilots and the ones who want to digitize old analog video tapes. I fall into both categories, but unfortunately the video cable from my device got burned in an accidental fire that also cause my video blog RTFMS to halt for a really long time. Long sad story …

Anyways, I was repairing the cable recently and decided to pinout it since there seems to be no information in the internet about this very custom cable. So in case if you want to build your own cable here is how it is interconnected:

May 15, 2013 Using Jive Managed Snippets Plugin

Managed Snippets Plugin for Jive is awesome. It allows administrators to define sort of “macros” that can be reused on a Jive portal. The best part is that it allows to workaround the regular limitation for using javascript and HTML tags. Yes, that’s right, you can use Javascript, IFRAMEs and all HTML tags in the managed snippets. This is a very elegant way to allow users use limited and well-managed Javascript without exposing site to XSS attacks.

Originally this plugin was only available for place types only. For instance you can insert it via Customize->Other->Managed Snippets menu into a group overview and include a google map for instance. However as of you can also use it in user posts, documents, virtually any objects. Here is how you can do it and a few caveats:

The default login for the admin user for the JBoss Enterprise Application Platform (EAP) 5.2.1 and other v5 versions is “admin”. The passwords is obviously also “admin”. However if you try those right after the installation they won’t work, because you need to patch two files:

May 8, 2013 make: /opt/local/bin/ginstall: No such file or directory

make: /opt/local/bin/ginstall: No such file or directory

This happened to me while running bundle install on json v1.7.7.
The fix is

# sudo if necessary
ln -s /usr/bin/install /opt/local/bin/ginstall

May 8, 2013 Installing Oracle XE 11g on OpenSuSE 12.2 and similar

Overall the installation is pretty smooth, just follow the instructions on Oracle website.

There are two minor hiccups though:
1. cannot touch `/var/lock/subsys/listener’: No such file or directory

This error is cause by the fact there is no /var/lock/subsys directory in some Linux distros, so you need to create one. Before you run “/etc/init.d/oracle-xe configure” run

mkdir /var/lock/subsys

2. The second one is trickier. When you run the configuration wizard it fails while configuring the database and the log files contain something like

==> cloneDBCreation.log < == alter system disable restricted session * ERROR at line 1: ORA-01034: ORACLE not available Process ID: 0 Session ID: 0 Serial number: 0
