The Sunk Cost Fallacy is a real pain. It's a cost that you sustained in the past (be it time, money, energy, whatever) and cannot be reversed, cancelled or undone. The fallacy is that yet knowing about the sunk cost of a project, you are often tempted to justify your future investments because of your past (most likely lost) investments. The sunk cost should not influence your future decisions, yet it does. And the outcomes are often delusion, sadness and stress.

Iâm going to outline an example to make the concept clearer:
You need to send a recurring email to some users (a newsletter for example), based on some business logic.
The business logic / user story could say:
"As a user
I want to receive an email every week
So that I can stay up to date with the latest news."
This is intentionally a contrived example to reduce the scope of the exercise.
Topics, Approaches and Tools
Concepts discussed below are
- SOLID principles
- Single Responsibility Principle
- Open-Closed Principle
- Dependency Inversion Principle
- Reason for a software component to change
- Test doubles like Spies and Stubs
- Collaborators in tests
- User Acceptance tests
- Unit tests
On the technical side, I am going to use the following tools
- sinon for easy Test Doubles
- ava for running the tests
- MongoDB as an example, but of course the persistence can be changed at your liking
- no real email API service, to keep it simple

As soon as Elixir was released a few years ago, I got into it and started learning and building things with it. Thanks to the help of some dear colleagues I had the opportunity to get valuable feedback and learn even more concepts about GenServers, the BEAM virtual machine, ETS and Erlang+Elixir in general. I also went to my first Erlang+Elixir conf, and had the chance & honour to meet Joe Armstrong, #rememberingjoe. On 2020/04/22, during quarantine, I decided to get back to Elixir (who knows: maybe even dabble with Erlang directly). I post-poned this too much now, it's time to get back to the distributed programming world. Without further ado, below my journey (in form of a daily journal) about learning more about Elixir (again), the BEAM, plausible analytics and things discovered along the way!

devblog is yet another lightweight static site generator. Although there are widely used SSG like 11ty (which this blog was previously based on), Jekyll (also previously used), GatsbyJS and many others, I wanted to get my hands dirty and understand how to make the process of building a static blog even simpler, if possible. Even simpler in the sense of "it does just what I need and nothing more". Install via npm i -g devblog or create a blog with a one-liner npx devblog init my-new-blog, cd my-new-blog and serve with npx http-server _site 8080. It's that easy. Rebuild the blog by running npx devblog (or npm i -g devblog and then just run devblog in the main directory) Continue reading my story of building devblog.2020-03-27

As you may be accustomed by now, in the JavaScript scene there is almost never a single way to program. I think it`s very difficult to find an idiomatic styleguide for the language/framework. What I found is that lots of intelligent people were talking about idiomatic solutions they found to write maintainable AngularJS applications, and some similarities caught my attention. One of them was the preference to use the controller as syntax, I definitely do too, and here is why.

Angular is a JavaScript framework for creating modern web applications, which are inherently declarative, modular, with testability in mind.

It was very interesting to see [his progress](http://joebew42.github.io/events) and keeping track of his studies and interesting reads over the course of over 4 months! [Heres my take. Now I want to try it and to see it as a log and motivation/reminder to study regularly. I will also use it probably as a aid to review the studies and to visualize the progress. Finally I will also find a way to integrate it with pomodoro.cc, I`m sure about that..2021-02-11

AppCache is a nice guy when it comes to caching stuff, but at the end of the day it is just a fucking douchebag. For me AppCache is a smelly, almost invisible, annoying little parasite. If you're having trouble cleaning up the mess this guy did (aka invalidate the cache), these simple steps will lessen your burden and throw this douchebag out of the parents' house.

If youâre trying to finish a coding kata in a pomodoro, youâll most likely have a hard time.
I was sick of almost never finishing a kata, but then this idea hit me:
It would be awesome if you could start a kata from a fresh, already set up workspace, with preconfigured test framework and boilerplate classes.
I found two options suitable to support this workflow.

Let's say you want to filter odd numbers from a list of numbers, like
[1,2,3,4,5,6] should become [1,3,5]. One way to solve this problem in a functional fashion is to provide an odd filter function, that is internally composed by a negation of an even filter on those numbers.2015-04-27

First of all I would like to explain why:
In my opinion sometimes you can write some of your E2E tests and your User-acceptance tests in one go, together.
Iâm not saying all of them, some E2E tests can cover exceptional cases and often are on the sad path in terms of UAT.
Both of them are rather flaky in terms of feedback and canât give any detailed hint where the test failed, except the approximate region of your application.
Both hit the application in the running state, so why not write some of them in the language of the business while testing technical aspects hidden behind?
Itâs just a thought, probably Iâm totally wrong and should read more about both aspects :)
Anyways:

Let's say you have an array of things. You want to provide to your user the ability to select two things from this array. If you use the
<select> tag you won't be able to select multiple options from this list unfortunately. You can either come up with a new directive that handles this, use somebody else's plugin, or roll your own Angular filter (probably for learning purposes).2014-08-02

Resizing an image to the desired size and proportion sounds like a simple process, but I found it quite challenging using Preview since I don't own a legitimate copy of Photoshop. Fortunately I came across a nice tool that exists since the archaic times of computers (for me at least), since 1999, that gives me very handy commands to solve this workflow. It's called ImageMagick.

Angular's DI in combination with lazy loading of dependencies is one of my favourite features of Angular. I was fascinated about the simplified API that Angular provides to make DI happen and the ability to create testable, modular code out of the box. Anyways we are here to look what's behind Angular's DI, so here we go.
