In unit testing, we often want to create mocks of other parts of our app in order to better isolate the particular component under test, and prevent us from dragging the whole dependency graph into our simple little unit test. Dependency graph of a component we want to test In the example above, we could mock out ListComponent, InboxComponent and MessageService and thereby forego the need to pull in all of the transitive dependencies (dependencies of dependencies).

If you, like me, were born in the 1980s, then you are a member of the final generation of analog natives - those who grew up during that period in which the Information Age reached the masses. Of course, all of humanity up until that point could be considered “analog native”; but uniquely, our generation is the one which experienced first-hand the transition from the analog to the digital world.

I write this from somewhere above Western Europe as I fly back to Vienna from the AngularConnect conference which just took place in London. Since a lot of the news and announcements from conferences typically take a long time to percolate out into the wider community, I thought I’d jot down a few notes of the things which I found interesting from the talks I saw (it was multi-track so I missed at least as much).

About 13 years ago I built a web shop for my dad’s company. Like many small businesses, the company does not have an in-house development or IT department, so anything vaguely website-related tends to end up in my inbox. This is how I recently found myself in a conference call with Dom from IntegriMart1, a company which provides marketing tools for websites. This type of business is known as a “marketing tech” company, sometimes abbreviated to the crap-sounding “martech”, and a close cousin to “adtech”.

I have just converted this website from an AngularJS app backed by the Wordpress REST API to a static HTML site powered by Hugo, a static site generator written in Go. This post explains my reasoning, experiences and thoughts about the results. Back in 2014 I was learning AngularJS, and I decided to build my website with it as a learning exercise. I wrote about it here. I was happy with the design, but there were a number of issues with which I gradually grew dissatisfied.

When we talk about productivity, it is usually in the context of our professional lives. Is this fair? Does productivity begin and end at the office door? I’d like to address this question indirectly, by backing up and taking a high-level look at the subject. No tips or “weird tricks” here; rather some brief thoughts on the scope of productivity. Productivity is happiness. Happiness is the sensation you get when you progress towards a goal.

In software development, we often hear and speak of abstractions. When we use this term, we often mean some variation on concepts such as “hiding the implementation details”, “providing an interface”, “modelling a data type” or even “removing duplicate code”. But what is the essence of abstraction? The origin of "abstract" in the Macmillan Dictionary for Students I was recently looking up the term “abstract” in a dictionary, and was struck with the origin of the word:

Earlier this week I set out to convert a few of my Angular 2 apps to use Ahead-of-time (AoT) compilation. I’ve just been to AngularConnect and heard about a project named “@ngtools/webpack” (video here) which supposedly allows you to use the same build tools that the angular-cli project uses, even if you don’t use the cli (which is the case with my stuff right now). So I eagerly searched out@ngtools/webpack on npm and found this:

SKQW (pronounced “skew”) is a native desktop audio visualization application written in TypeScript with Angular 2, and implemented on the Electron framework. It is currently in alpha and a compiled binary only exists for Windows, but I’m hoping that - if there is interest - I can push the project forward and improve stability, features and of course bring full support to Mac OS X and Linux.
