Progressive Web Apps (PWAs) combine the best and newest features of the Web to deliver an experience that rivals native applications on mobile. Even better, they work on desktop, too. In fact, they work everywhere that the Web works! "Ah", you say, "that's not true! They require features that don't exist in all browsers." Because PWAs are "progressive", they can adapt to older browsers to deliver the best experience possible given the features that are available.

Switching costs are an important part of software development. When my software relies on one service, the amount of time I have to spend moving it to another service is called a switching cost. In general, you want these to be as low as possible. The reason is that if the service you are dependent on ever becomes unsatisfactory or even harmful to you, then you need to be able to switch to a competitor service.

BCP.exe takes 15 minutes to complete but I only see a few seconds for the BULK INSERT command when monitoring dm_exec_requests. What is taking so long if the BULK INSERT is only showing a few seconds in dm_exec_requests?

PHP7 is out. This isn’t news. It’s been out since last December, with nine minor revisions since then. What’s new is that it’s serving all of Wayfair’s customer-facing traffic. Performance-wise, PHP7 is the rocket ship people said it would be. We’re nothing but pleased. If you can upgrade, you should do. Read more.

Since Frances and I published a blog post last year introducing Progressive Web Apps , a healthy conversation has started about what is and isn’t a PWA. There are a lot of opinions and many shades of gray. What are the hard requirements? Which requirements are marginal? What’s aspirational? This article outlines these requirements, attempts to classify them, and provides a baseline for “what is a Progressive Web App?
