The token comes from your acquirer (eg Stripe), not the bank-- the acquirer is the one holding the card info, then when you submit a request to your acquirer, they perform a lookup on the token, grab the card data, and do the real lifting o

The Scala landscape is very, very quickly creating their own libraries for similar popular Java libraries/frameworks. It is entirely possible to create an application, web or otherwise, that uses no Java libraries at all (save for the

Am I missing the obvious? They're using text columns as blob stores for JSON data? How on earth do you query that in MySQL? How do you run a secondary index, on say the user_id? Is it just one gigantic instance of Elasticsearch or Luc

That's fine for simple one-off apps that don't require serious infrastructure, but Heroku is just ridiculous with its pricing if you need any kind of complexity. I can burn through 1GB of Redis cache really easily; on Heroku, that

James Archer, author of the piece, is Chief Creative Officer of both Crowd Favorite, and Forty, both of which use -- surprise -- the hamburger menu in their mobile sites. Is this another case of "do what I say, not what I do"?

Except most people deploy dual HAProxy servers connected via heartbeat, which share a floating IP. There's no SPOF. Deploying new microservices is as simple as managing the HAProxy config file via Chef or Puppet.

I would imagine that once HTTP/2 becomes a serious implementation, this kind of thing will be unnecessary.

Blocking in Play should be foreign. On modern hardware architectures, writing code that blocks is the equivalent of throwing up your hands and saying "I can't trust myself to write efficient code so I'll just scale out my h

It's funny. An "Introduction to Modern Java Web Development" sounds like a primer for the Play Framework, Scala, and Akka. Each of the examples looks like the starter documentation for Play, in that you've got your json

Surprisingly enough, before the 2014 season with brake-by-wire, drivers would have to adjust the brake bias (forward vs rear) by moving a little lever down next to their knees. They'd be taking their hands off the wheel all the time .

An Akka actor simply must not issue a DB call That's untrue. With Akka's pipe pattern, you can take the results of any future and pipe it back to the sender, including using a map on the future if you like. This is how we do rea

A good Scala programmer will never write the word null in their code. Ever. If I was overly concerned that the method was going to be called by Java code, I'd put this: Option(s).getOrElse(List[String]()).filter(str => Option(st

This is completely untrue. Every single Java developer that I introduce to Scala-- every single one-- six months later, they tell me "please don't make me go back to Java". The "disenchanted" piece, I think, comes f

I don't think that's right. TraversableLike, and FilterMonadic will both size up the resulting return value based upon the length of what's passed to it. You'll get a List of N items, and the call to flatMap will also tr
