I used war and peace to explain to a CEO how wasteful a mobile API was; twelve distinct items of data to display but we sent JSON larger than war and peace.

The D in SOLID is for dependency INVERSION not injection. Most dependency injection that I see in the wild completely misses this distinction. Inversion can promote good engineerin…

Try flutter - in my experience it is the shortest path from idea to working application.

In my experience this is a superb way to rapidly create bad integrations with AWS. Some of the simple things will be easy, everything else will be hard. Also instead of supplying a…

I wish I could upvote this more - if I can’t do it in CloudFormation I won’t use it.

If you don’t know front end development Flutter can get you a very long way very quickly.

The plastic and wooden winders make tables wobble as well in my experience.

More accurately - Google migrates chrome application to web application. 'Google Kills Keep' is inaccurate.

It depends on how you define your 'unit'; a unit can be as large or as small as you require. But, I'd suggest if you can't test a single class in isolation easily (and you might ne…

X can be a check digit. From memory the check digit is calculated using a modulo 11 calculation.

A philosophy of software design - John Ousterhout This has an interesting generic discussion of API design which is technology agnostic.

Read shorter books!

I’ve seen one service per database table, and have had architects seriously think that a table equals a bounded context. Then they try to work out how to do two-phase commit across…

Having worked on multiple systems that have done similar things to this, I'd fall on the side of no! If you're not really careful the assertions will quickly obscure the actual log…

I got taught them in a course on linear systems which was a pre-requisite course to control theory. Lots of electrical circuits, mechanical systems and electro-mechanical systems c…

You can minimise the number of gates but that doesn't minimise the number of transistors as that varies by the type of logical operation performed by the gate. Practically you prob…

My key reading from the article was over-fertility leads to mono-culture, so paradoxically you need to reduce soil fertility to encourage diversity. Reducing soil fertility probabl…

From memory go fmt will use both tabs and spaces when formatting but it uses tabs for indentation from the left margin and uses spaces for some alignment of variables - so it doesn…

How do you manage AWS credentials? We use short lived credentials that are stored in the standard file system location and expire frequently, can your application just use these? W…

This doesn’t seem to offer useful authentication to me like public / private key pair can with JWT. In order to authenticate I will need to know the secret key.

It has caused us failures as lambdas have scaled up as it is quite easy to hit a rate limit.

Two similar books by Stansislaw Lem would be His Master's Voice and Fiasco.

The article linked from here on integrated tests, http://blog.thecodewhisperer.com/permalink/integrated-tests-... is also well worth reading.

How will cryptography libraries ever develop if someone doesn't roll their own?
