Would like to ensure all additional MATLAB support packages are installed on the share location:
1. launch matlab as “root” user
2. find out the current support package root (default is homedir:
3. set it to a share location:
4. To change the add-ons installation folder
On the Home tab, in the Environment section, click Preferences > MATLAB > Add-Ons.
5. To install support packages, on the MATLAB Home tab, in the Environment section, click Add-Ons > Get Hardware Support Packages.
The USB Webcam does not work in RHEL6 due to some libraries, but work fine in RHEL7.
Always remember to put full path of the scripts or commands to be run in crond.
I had been troubleshooting cfengine segfault for days and finally found the issues:
Network setup in the kickstart %post had enable networking_ipv6, which confuse cfengine
It was a broken kickstart since long time ago, and the workaround was rerun “cfagent” again. Not a very good workaround.
Anyway, by copying and mimic some necessary changes in %post for network setup fixed the issue!
This is the final solution that I had done in my kickstart.cfg:
network –bootproto=dhcp –onboot=on –noipv6
to ensure ipv6 will not be activate during or after kickstart.
Here is some basic steps (and reminder to self):1. install pulseaudio-utils
# yum install pulseaudio-utils
2. Check which output to can be use:
# pactl list
** find the output you need, the 1 I am outputing is "output:hdmi-stereo-extra2+input:analog-stereo"
** you might need to start "pulseaudio -D"
3. Set the default output:
# pactl set-card-profile 0 output:hdmi-stereo-extra2+input:analog-stereo
4. To make the changes permanent, append/insert/edit /etc/pulse/default.pa:
set-card-profile 0 output:hdmi-stereo-extra2+input:analog-stereo
And this should be able to play sound output to DisplayPort.

In the past, I had been using kSar to quickly plot graphs from sar files that I had collected from the systems, but I would really prefer a system that it can consolidate all the sar reports from various systems and generate beautiful graphs to do performance analysis.
I know there are tons of tools out there that can do that : Nagios, Sensu, Shinken, Cacti, just to name a few, but all these is generating the graphs base on the data it collected instead of the sysstat sar file located in /var/log/sa.
I still haven’t find any that do that, but the closer I found is SarGraph, which will run a periodic sar command remotely to systems and keep the data on the sargraph servers. Currently it only give 4 performance metric: CPU, Memory, Swap and Run-Queue Size.
After a few weeks of testing and experimenting, finally found out the issue of the setup:some repos were not enable by default
Now, I had figure the issue and put the changes into cfengine (yes I know is old school) and will also include in ansible playbook (WIP).
I don’t know how to cook except fried egg, and boil water (for instance noodles and 3 in 1 coffee/tea).
I don’t know how to play any music, can’t even sing without hurting others’ eardrums.
I don’t know how to sew – can’t even sew back a button on the shirt.
I don’t know how to …
What am I good in doing? Maybe only 1 thing I am really good in – being myself!
