Hands On AWS - Massively Scalable Image Hosting Using S3 and CloudFront - Part 1
If you are building software apps, at some point you will likely need to build an image hosting service (let's be honest, probably more than once!). Image hosting is a core feature of many apps, and it's important to get right. We all know the best practices for building image hosting in the…

Your Most Important Skill
Technology is changing rapidly and it is a major investment to learn a new skill, technique or technology. Our knowledge gained is so hard fought that it is only natural to rely on it dearly. But it's a mistake to hold on to this knowledge for too long - you must be open to new ideas. In this...
