Slow Ubuntu 9.10 on a Dell Inspiron 6400

Submitted by litrik on

After upgrading a Dell Inspiron 6400 laptop from Ubuntu 9.04 to 9.10 the machine was so slow it was barely usable. top was showing a load average of 7 after opening Firefox or OpenOffice.

Strangely no command was using more than 10% of the CPU, memory consumption seemed pretty normal and there was barely any disk activity. But the system was painfully slow.

Using content-check.pl to monitor a Drupal site

Submitted by litrik on

One of the scripts in my bag of tools to check whether a site is still up and running is content-check.pl. This little script compares the hash of a web page against a previously created reference hash. If the content of the web page has modified, this script will detect it and send an email.

You have to be very careful which page you check because even the slightest difference in the HTML source will be detected.

HTC Hero does USB tethering on Ubuntu

Submitted by litrik on

The user guide of the HTC Hero explains that Windows users can do tethering through the (Windows-only) HTC Sync software. I assumed that tethering on Ubuntu would be impossible without rooting the phone - just like any other Android device - but I was wrong.

It turns out that USB tethering on Ubuntu is even easier than on Windows
