It’s very easy to convert PDFs to HTML on Ubuntu.
The command is pdftohtml
This is a GlobalSat DG-100
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.
One of my pet hates on the internet is shopping sites which resize the window when you’re looking at a zoomed in image. Not all of us still use a windowed browser, in fact, most people now use a tabbed one.
Selective colour replacement is easy from the command line with imagemagick.
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
So, you’re using sendmail to try and send emails from php/wordpress and it’s not working?
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…
sendmail_path = /usr/sbin/sendmail -t -i
This page has the permalink http://www.john.geek.nz/2010/04/wordpress-permalinks-and-404-errors But internally its default URL is http://www.john.geek.nz/?p=1495.
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?
I upgraded to Ubuntu 9.10 in early December, but yesterday was the first time I tried to use headphones since then.
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)
Use the arrow keys (left/right) to highlight Headphon
This should fix it. You can now hit Esc to exit and exit the terminal.
If you get the error “Not available in the current data” in the Ubuntu Software Centre, try opening a Terminal and running this:
sudo apt-get update
Update: This should also fix the error “Not available for your hardware architecture” as well
