I'm at the Magento Imagine event in Las Vegas right now and I thought it would be fun to create a swagpile: all the goodies that the sponsors at the event have with them.
So here it is! We have T-shirts, noteblocks, sunglasses, earbuds, sweets, chocolate, guitar pick, sunblock, frisbee, phone holder, stressballs, rubics kube, mugs, flipflops, armbands and a flashlight. There's even a brontosaurus and a pretty Angry Bird in there! Also: Magento has a great goodie store at the event so make sure to stop by if your at the event. I will write a more in-detail post about the event itself later on!
Recently I've seen some (often absolute) statements going around, generally in the line of "open source commerce platforms are a terrible idea". Now of course different solutions always have different pros and cons.
A hierarchy of evidence (or levels of evidence) is a heuristic used to rank the relative strength of results obtained from scientific research. I've created a version of this chart/pyramid applied to CRO which you can see below. It contains the options we have as optimizers and tools and methods we often use to gather data.
