Recently we discovered something strange with our Bing search ads. A bing ads traffic partner named Inversemedia was generating traffic for our websites. However, the main traffic was generated on an ad group that targets a single very specific ‘exact match’ keyword. Inversemedia generated twice the amount of impressions compared to the Bing and Yahoo! Search Properties for this ad […]

By rotating the headers you can add many more columns to the viewport while preserving readability. If you wish to implement something like this yourself there are a few things to consider: The table-layout needs to be fixed. This […]

When I first started programming in ColdFusion I used the cfhttp tag quite a lot. However, the cfhttp does not have an insecure option. This means you have to install the website certificate for each website you wish to connect to. As far as I know, this cannot be automated. And btw installing a certificate in the ColdFusion truststore is […]
Jump to the code Recently one of our websites became almost completely unresponsive. At first, we had no idea what was happening. Using Wireshark and looking at the IIS log files we noticed a huge amount of traffic coming from multiple ip’s all with the same User-Agent. The user agent contained the string 80Legs. We quickly discovered that 80legs is […]
I always wanted to create a simple example on how you can create objects in javascript. The example also contains private and public variables and functions.
