Danger-todoist celebrates 200k downloads

Published on January 17, 2018 路 251 words 路 about 1 min reading time

Danger-todoist is a plugin for the excellent Danger ecosystem. More specifically for the ruby variant of Danger. What does Danger do? It is basically a kind of automated code / pull request review system. You create a pull request on github, and a bot account will recommend changes to the pull request. The changes it suggests are based on a freely configurable set of rules and suggestions, as codified per your Dangerfile. The beauty comes as always through the flexibility of just plain ruby code and a set of plugins.

One of those plugins is danger-todoist, which I first published in September 2016. A things that makes me cringe is leaving TODO: fix me comments all over our code, and of course then never fixing them. Makes one wonder if there really was something to do ... 馃.

Danger-todoist helps you with this! It will duly notify you if you were to leave an unadressed todo comment in your changes. You can decide whether this is a show stopper (YES!) or if you want to leave it as a warning. Either way, this makes it much harder to let many of those pesky comments sneak into your codebase.

Since its first release more than a year ago, it has now amassed 200.000 downloads as shown on rubygems. This likely makes it my most successful peace of open-source software to date 馃枛馃徑, which I hereby celebrate.

Hack on, and keep that code clean, and check it out on github.

My 2017 podcast winners

Published on December 22, 2017 路 342 words 路 about 1 min reading time

In 2017 I have likely listened to hundreds of hours of podcasts. Out of interest, lets do the math real quick: 50 weeks until now * 5 podcasts * 1h average length = 250h. So yeah, hundreds of hours it is. But I definitely don't consider that to be wasted time, but sometimes great entertainment, time spent learning, or a soothing tone to fall asleep to. Without much further ado, here's what I have been listening to in 2017, in no particular order:

Living off of open-source

For the second year in a row now I have participated in Hacktoberfest, an open-source initiative by DigitalOcean, a cloud infrastructure provider. What's the deal? You, fellow open-source contributor, just have to open a handful of pull-request during the timeframe of October 1st to 31st. DigitalOcean will be generous and send you a limited edition t-shirt for free (well, for your time spent on those 5 pull-requests that is). Here's the two shirts I got for my 2016 and 2017 efforts:

Needless to say, I find that an awesome initiative, seeing that the world builds upon open-source software. The five pull-requests that got me my t-shirt this year were:

To finish this off I can't recommend participating in Hacktoberfest enough, and thanks to DigitalOcean to appreciate this by giving you a t-shirt.

50 Million Lines of Bugs

I often think about the following Mercedes-Benz advert:

In what world having whatever many lines of code should be something to brag about is beyond me. The tweet already hints at this nicely. But the marketing department seemed to have a different opinion in this case.

While I don't have credible numbers to back this, I think we can agree more code correlates with more bugs in some way. So Mercedes-Benz, please, try to keep the number of lines of code in your cars as low as possibly can be.

Lucky Crystal

Published on December 3, 2017 路 243 words 路 about 1 min reading time

In the ever changing landscape of web frameworks, there is a new kid on the block: Lucky. Lucky is written in Crystal, a statically typed programming language heavily inspired by Ruby's syntax, which claims to be

Fast as C, slick as Ruby

For this blog however, being as fast as C is mostly irrelevant, I'm sure it'd be plenty fine running in Ruby as well. What I rather value is developer productivity, or "getting something done in half an hour before going to bed". On that end, the Lucky + Crystal combination performed pretty well and I got a rewrite of this website shipped in a few hours of work.

Type safe html

What I find super interesting about Lucky is the way it deals with the task of rendering html. While the plethora of templating engines like ERB, Twig or Crystal's ECR are easy to work with and simple enough to understand, there's something about using plain Crystal code to markup html. The following gist is an example method from this blogs source code:

As you can see it was trivial to extract methods to render reoccuring or more complex parts of the layout. It's just code. Also the compiler will complain if we produce invalid code, so we cannot forget to close tags. That's kind of a big deal to me.

I look forward to spending more time in Lucky and Crystal, they both get a thumbs up for now!
