April 18, 2019163: Building SaaS Products with Simon Bennett
In this weeks episode we chat to Simon Bennett about his experience bootstrapping SaaS products.
We start off with how he got into software development and highlight some of his previous/current business ventures.
This leads us to highlight treating each failure as an experiment, and the danger (as a developer) of using a new product idea as a platform to learn new technology.
From here, we discuss the success he has had from SnapShooter, his new product Automaily, and the unique challenges building products targeted at developers.
Finally, we touch upon how he comes up with new ideas, the necessity to quickly validate them, and advice for any listener who has an idea and is thinking of building a product from it.

April 11, 2019162: PHP + JIT = GR8 with Joe Watkins
In this weeks episode we have good friend of the show Joe Watkins back on to discuss the recent developments in PHP.
We start off by highlighting how code is currently compiled and executed using the Zend VM, and distill how the recently approved JIT (for PHP 8) will change this.
From here we mention the reasoning for going down this path now, the difference between I/O vs CPU bound code, and the use-cases where the JIT will improve performance.
This leads us to the PHP compiler project Anthony Ferrara is working on (with the goal of Ahead-of-Time PHP compilation), and the new parallel concurrency API Joe is working on which uses a model similar to Goroutines.
Finally, we discuss his recently approved Weak References and Abolish Narrow Margins RFC’s.

April 01, 2019161: Exploring Bitcoin with Mattias Geniar
In this weeks episode we are lucky to have Mattias Geniar back on the show to discuss his experiences delving into Bitcoin and Cryptocurrencies.
We start off by chatting about his introduction to Bitcoin, the ‘bear market’ of 2018 and how valuable the ‘Mastering Bitcoin’ book is to understanding its’ internals.
From here we move on to the concept of ‘Code is Law’ and the implications of such an approach, the pros n’ cons of being a developer in this space, and how he stores his private keys (not your keys, not your coins!).
This leads us to highlight second-layer scaling solutions such as the Lighting Network, and the confusion around projects reusing the Bitcoin name.
We then touch upon the power of Ethereum, its’ planned consensus transition from PoW to PoS, and how different it is developing on a distributed platform.
Finally, we look at the Mimblewimble protocol and Atomic Swaps, discussing their use-cases and how they can improve the space.

February 23, 2019160: Serverless PHP using Bref with Matthieu Napoli and Neal Brooks
In this weeks episode we are lucky to have both Matthieu Napoli and Neal Brooks on the show to discuss all things Serverless PHP.
We start off by discussing what drew Matthieu to Serverless, the creation of the Bref project and the technical challenges encountered with getting PHP to work within the Lambda environment.
From here, we touch upon the reasons behind moving from the Serverless Framework to SAM (for the 0.3 release) and how Bref uses the new Lambda Layers and Runtime API.
This leads us on to highlight how a typical PHP project would use Bref, the decision to be opinionated in order to stay minimal and the experimental Loop SAPI.
Finally, we envision what the future holds for the Bref project and Serverless compute.

January 08, 2019159: PHP Test Tooling and RFC Roundup with Joe Watkins
In this weeks episode we are joined by Joe Watkins for a long overdue catchup.
We start off the show by discussing what Sandboxing is and the new Sandbox extension he has developed.
From here, we touch upon test-doubles/mocking frameworks, the reasoning behind building uopz in the past, and now componere/mimus to aid in testing.
This leads us on to highlight what test coverage is, the history of coverage tooling within PHP, and the new exciting pcov extension he has released.
Finally, we do a big ol’ RFC roundup, discussing RFCs that have been accepted for PHP 7.4 (FFI, Typed Properties and Preloading) and ones under discussion (JIT and Weak References).

December 03, 2018158: Hexagonal Architecture (Ports and Adapters) with Matthias Noback
In this weeks episode we are lucky to have Matthias Noback on the show to discuss software architecture design.
We start off the show by highlighting why we should invest time in the architecture of our software, and what is meant by ‘layers’ of an application.
This leads us to discuss what Hexagonal Architecture (Ports and Adapters) actually is, Infrastructure vs. Core (Domain, Application) and the Dependency Inversion Principle.
From here we mention the different responsibilities Ports and Adapters have, the different forms of testing you can do within this architecture and Use-cases/Command Buses.
Finally, we touch upon the new book ‘Style Guide for Object Design’, which Matthias is currently in the process of writing.

September 28, 2018156: Running Symfony on AWS Lambda with Neal Brooks
In this weeks episode we are lucky to be joined by Neal Brooks, a fellow developer of Edd’s at MyBuilder.
We start off by discussing how he got into programming, QBasic and video driver shenanigans.
From here, we move on to introduce his SymfonyLive London talk ‘Running Symfony on AWS Lambda’.
We highlight what drew him to Lambda, and the new tooling that is making it easier to run PHP and frameworks (such as Symfony) on it.
This leads us to cover his demo application, and explore handling assets using S3, database migrations and AWS resources using CloudFormation.
Finally, we debate using catch-all gateway endpoints vs. dedicated gateway endpoints and Lambda performance.
