Tuning Odroid U2 headless server

Posted 10-19-2013 at 05:18 AM by Pyplate

I've been working on my Odroid U2. It has a quad core Cortex A9 ARM SoC running at 1.7GHz, and 2GB of RAM. I've set up Apache and installed a copy of my web site. I set up Varnish Cache and I'm running tests to see how much of a performance boost I'm getting.

I had some issues with the Odroid hanging every few hours. I installed a new kernel and so far it's been up for 18 hours. I'm using a 16GB class 4 micro SD card. I might try using a class 10 card to see if it performs...

Bash script/utility to wait for keyboard and mouse inactivity

Posted 10-18-2013 at 06:42 PM by the dsc (linux-related notes)
Updated 10-22-2013 at 07:52 PM by the dsc

Sometimes you may want to have some script periodically popping up some interface or something, but it may be somewhat abrupt, interrupt something you're doing with the mouse, or keyboard. So I came up with this tiny utility that will wait for the time given as a parameter, then exit.



Code:
#!/bin/bash
a=0
time=$1
if [ -z $time ] ; then time="1.2s" ; fi

while true ; do

mouse1=$( xdotool getmouselocation --shell

On Site Optimization

Posted 10-16-2013 at 07:32 AM by Pyplate

I've written a post about site some of the techniques I used to optimize my Raspberry Pi site.

I've minified Javascript, re-arranged CSS, and adjusted the way Javascript files are loaded. Google Analytics shows a pretty good improvement in page load times. There's still a lot more optimization to do, but I think I've made a good start.

I'm also working on setting up an Odroid U2 as a high speed web cache. So far I've installed Xubuntu, got my site running in Apache...

Is it ignorance or deliberate rip off?

Posted 10-15-2013 at 04:07 AM by Leo-duke

As a retired person I have the time to help other 'older persons' learn to use their computers, and carry out simple software repairs and set-up. I was therefore deeply shocked on two occasions by clients having been well and truly 'ripped off'.
In the first instance a lady had problems opening a programme (OK, program), so took her laptop to PC World. Here she was told that her computer had failed, was out of warranty and she should replace it. They sold her a top of the range unit, better...
