Cheap Tricks to Fullfill Your Need for Speed

As I’ve mentioned countless times, the performance of a website can really make or break a user’s experience. Everyone places emphasis on tuning and sharding databases, and buying multi-threaded and multi-core processors. These are all viable solutions but they are either pricey or labor intensive. So what are some quick and clean ways to improve the performance of your web app or web service? Start with the slowest moving part and work from there, disk I/O, or more specifically data base access ... Read more

It took me only a few hours to write the test cases I needed using stubs, and with and IDE it’s even easier. But I don’t think its a fair assessment to compare using Mocks to Stubs because each tool is used for a different purpose (behavioral vs. functional). However, I did notice one very ... Read more

At the time I thought I was making the right decision. Having my own life and my own territory was ... Read more
