Using The Volvo 440 Diagnostic System

 

The Volvo 440 dates back to an era where Car manufacturers were actually helpful (or at least some of them were), and as a result has a built in Diagnostic system. No going to the Garage to have fault codes read, so long as you know how to use the system.

This article tells you exactly how to do just that!

POST Data going missing in PHP

I came across an incredibly frustrating issue earlier today, whilst building a class to parse data and insert it into a database I discovered some serious data loss. Sniffing the traffic showed the data was being submitted, but when I tried to access it in PHP bits were missing!

Consider the following

Raw Post data: foo=blah+blah+blah&bar=This+is+a+block+of+text%0D%3Cbr%3EThis+is+line+2&zulu=bah

So in PHP, you'd expect that;

  1. echo $_POST['foo'] would give "blah blah blah"
  2. echo $_POST['bar'] would give "This is a block of text<br>This is line 2"
  3. echo $_POST['zulu'] would give "bah"

Unfortunately, this isn't the case! Instead number 2 returns "<br>This is line 2". How very frustrating, but thankfully I eventually found the solution

Resolving KDE issues with Dual Monitors

Although the issue is apparently fixed in KDE 4.6, many aren't running this version yet.

This documentation shows a workaround that can be used in order to get KDE to remember the settings.
