#indie #economics 

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.

#nodejs 

#javascript #analytics 

Do you want to know how users make use of your site? Which links they click most and what converts most?

From the official documentation you can trigger custom events via JS, by including a small utility function plausible:

<script>
window.plausible = window.plausible || function() { (window.plausible.q = window.plausible.q || []).push(arguments) }
</script>

Whenever you call plausible('...event...') you put a tracking event in a queue (window.plausible.q) and will be tracked.

{ "_id" : ObjectId("5f034cea0b15686f5d78baf0"), "subDocument" : { "field3" : 3, "field4" : 26 } }

#elixir #analytics 

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!

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.

Today I started using joebew42`s daily activity log concept.

It was very interesting to see his progress and keeping track of his studies and interesting reads over the course of over 4 months!

Here`s 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..

I ran into this gotcha today as I was playing with Plug of Elixir.

#angularjs 

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

Angular`s digest loop is like a baby: you need to take care of it and feed it well, or it will puke all over your nice shirt. Actually, it will probably, eventually do it anyway.

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.

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.

Recently I got the opportunity to work in a legacy, and wanted to share what I learned about gaining confidence and still deliver business value.

I hope this will help you to push your productivity level to the edge and to find the ultimate flow to contribute to open source projects with ease :)

You need to install hub, which is a tool that will wrap your git cli tool with some useful utility functions to interact with GitHub.

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).

Drone listens on port 80 by default. If you want to host your application on the same server, then that's an issue.

There are countless continous integration continuous integration tools: Travis, Jenkins, Shippable, Circle, CodeShip, Wercker, etc.

#imagemagick 

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.

#mongodb 

Let's take a simple example: a TicTacToe gamefield saved as a nested array in MongoDB.

In the Collection a gamefield document has the following structure:

Let's say you made a jQuery plugin and want to have an output (like a list of search results), whose aspect and format can be defined by the user.

Theory

The theory is very simple:

With a JSON file/object and the template the user provided you can create a basic templating system.

Disqus is definitely one of the best commenting systems out there (not to mention that it is responsive). As a speed freak I'm always concerned how much assets a website needs to load, affecting the overall load time of it.
