It’s an amazing piece of Kit, but the software that comes with it is absolutely rubbish.

You can download all of the routes (and delete them from the unit) in one simple command with gpsbabel.

gpsbabel -t -i dg-100,erase -o gpx /dev/ttyUSB0 outputfile2.gpx

You’ll still need to set up the times/distance for recording for the switch positions A,B & C. I have mine set to 1,5 and 10 seconds. Easiest way to set these up is on a windows machine with DG Manager.

Here’s how to stop javascript from taking control of your window size in firefox….

Firstly, Select “Preferences” from the “Edit” menu.

Click the advanced button…

And uncheck the “Move or resize existing windows” option.

Job Done!

You can download imagemagick from http://www.imagemagick.org/

The following will replace all red (#FF0000) pixels with blue (#0000FF)

convert sourceimage.png -fill "#FF0000" -opaque "#0000FF" destimage.png

It turns out that the plugin makes a huge difference.

Resource usage comparison over two (highlighted) tests. Cache is OFF on the left, ON on the right.

I kept increasing the rate of requests until the Disk IO rate was the same for both tests. With the cache turned off, CPU usage went through the roof to 400% of my allocation while still only serving up pages at five megabits per second. With the cache enabled, CPU usage settled at 20% and the data rate peaked at over 45 Megabit/sec.

I’m very impressed with the results… It seems that with a moderate spec server, you’ll hit your disk and/or network limit before you run out of CPU or RAM.

Are your mail logs (/var/log/mail.log) showing nrcpts=0 ??

Make sure the sendmail_path in your php.ini file (/etc/php5/apache2/php.ini) is set up correctly.

It should probably be…

1

sendmail_path = /usr/sbin/sendmail -t -i

Permalinks help people see the topic of a page before it’s visited and generally mean that search engines will rank them higher too.

OK, so you’re getting 404′s as soon as you enable permalinks other than the default?

Firstly, make sure mod_rewrite is loaded. The easiest way is to use the phpinfo() function. This can be done by creating a php file containing the following code:

1
2
3

<?php
phpinfo();
?>

You can then check the output of the phpinfo() function to see if ‘mod_rewrite’ in enabled.

If mod_rewrite is not enabled, you will need to enable it on the command line by typing:

1

a2enmod rewrite

You’ll then want to restart apache with

1

/etc/init.d/apache2 restart

If this doesn’t fix the problem, browse to the root of your website and check if the file ‘.htaccess’ exists.
If it doesn’t, create one by typing

1

touch .htaccess

Make sure the .htaccess file is writeable with

1

chmod 755 .htaccess

If it’s still not working, check your apache config files. The root directory of your website must have AllowOverride set to all. For example, in the file /etc/apache2/sites-available/sitename

1
2
3

<Directory /srv/www/>
	AllowOverride All
</Directory>

Just make sure the AllowOverride is set to All. The other items should stay the same.

Restart apache and hopefully your 404 errors will be gone.

Tell me how it goes…..

It turns out that plugging headphones into the headphones socket doesn’t automatically mute the speakers anymore.

Here’s a fix.

Open a terminal (Alt+F2 > gnome-terminal)
alsamixer (enter)
Use the arrow keys (left/right) to highlight Headphon
Press ‘m’

This should fix it. You can now hit Esc to exit and exit the terminal.

sudo apt-get update

Update: This should also fix the error “Not available for your hardware architecture” as well
