I still remember the days I tried to achieve UI testing with Selenium, PhantomJS and various other tools. It was a hassle. It didn’t run on CI because it needed some kind of window manager. It was unstable.

Setting up new projects is always exciting, but if you have done it a few times, it’s getting old quick. I have set up a few projects in the last time and I believe I have a nice setup going which I’m about to share with everybody interested. There is nothing new in here and if you are a seasoned Clojure developer, you might not learn much. If you are just starting out or have some work done in Clojure but need a working setup or some input on your current setup, you are at the right place.

Almost a year ago I wrote my last blog post on this blog. It wasn’t planned, it just happened. I was busy doing other, unrelated things and while I sometimes had something to say, I never took the time to take it to my blog. As with many things which are not top priority, it got lost along the way.

After “The setup“ and “The beginning“, my time with Clojure was somewhat limited due to pre-christmas stress. But this gave me time to reflect on what I learned so far, what I liked and didn’t like. I also attended the December Meetup by (clojure ‘vienna) and pair programmed Clojure for a few hours.

After “The setup“, I dove right into Clojure. As said before, I want to get to know Clojure by working on Advent of Code (AoC). I realize that coding puzzles and dojos and katas are not real world applications and one might miss certain things like performance or running an application in production. But they are small enough to provide fast feedback and to not hit a big wall. Even if I am not able to solve one, I can always skip that and keep going with another puzzle.

In the last week I started playing with Clojure. The reason for this are some upcoming projects with the blossom Team. The stack will most likely be Clojure in the backend and ClojureScript in the frontend. So I better up my game. I started with the Advent of Code to have some real world exposure and not just write complicated “Hello, World” code. I’m planning on writing a series of blog posts, documenting my journey.

In the upcoming weeks, I’d like to do an experiment involving Pokemon Go and the in-game currency Pokecoins. In short: I’ll work with a specific client for 2 hours each week doing my usual work and I’ll use the resulting money to buy Pokecoins. This work will be done on top of my current work.

If you are a seasoned Vagrant user, you know the problem around provisioning. If some software version changes, everybody needs to provision his or her machine again. Otherwise, things will fail eventually. You’ll also run into problems if running the provisioning twice fails for some reason (e.g. because a file already exists somewhere).

Using Vagrant in order to have a reproducible development environment is second nature to me. All projects I work on have a
Vagrantfile and it usually works great.

At blossom, we are running on Google App Engine (GAE). It’s nice to stand on the shoulder of giants and don’t have to worry about servers at all. GAE takes care of scaling up and down for us, handles our database as well as storage and gives us great insight into our production environment.

I struggle like most people with getting things done. I have read books and a lot of blog posts. Most didn’t work. I have implement some of the things David Allen suggests in “Getting things done”. I am keeping my inbox at zero most days with the tips from Andreas Klinger. But that’s about it. Nothing else ever worked - 5/3/1 tasks for the day, Pomodoro, keeping hand-written task lists, using various apps.

Many of you might already know it: Soon I’ll be joining the blossom Team on their quest to project management awesomeness. The current development stack of blossom consists of Python and Dart running on Google App Engine. In order to get some experience with both Python and Dart, I started a small side project which is a perfect combination of my two main interests, development and music.

What did you do last time you had a problem? The last time you couldn’t figure something out? Some people quit. Others try to force a solution on their own, applying insane amounts of time towards a problem. Often though, asking questions to the right people is the way to go.

After playing with Dart for a little while, I also looked into testing with Dart and learned that the test library can use PhantomJS to test the code that interacts with the DOM. Being a testing junkie, I wanted to give this a try but learned that I needed PhantomJS 2 to get it working. Beside running it in my VM, I also wanted to have it running on TravisCI. This blog post tells you how to set up both.

As announced on twitter, last week I ordered a batch of Jake. It arrived on Wednesday and I had to try it out the same evening. I’d like to share some thoughts about it and reactions I received. It’s only been a few days, so this is not some extensive review of the product or anyting.

Today I switched over this blog to be subject to continous deployment. Whenever I push a new commit (which might be a design change, new blog post like this or some small change), everything is build and automatically pushed to Github Pages, which host this blog.

If you are tasked with managing servers, you might have read about Ansible. If you do not know it, here is a quick intro: With Ansible you can define tasks which should be run on your (remote) hosts and Ansible takes those tasks, opens a ssh connection into your hosts and executes them.

If you are using vagrant on a daily basis, you might already be using something else than the base box suggested by vagrant (which would be the
hashicorp/precise64). If you are thinking about creating your own base boxes or are interested in the topic, read on. If you have no idea what I am talking about, the vagrant documentation can tell you more about Boxes.

Over the past two month, I have been building a new weekend project: cllctr. It’s a CD database you can use to store information about your CDs. Say goodbye to excel lists and over-the-top stuff as discogs or collectorz. cllctr is focused on the right amount of data, balancing the time needed to enter new CDs or organize a exisiting collection.

When I am talking about Vagrant at usergroups and conferences, one thing I always mention is that shared folders are slow, especially with Virtualbox. While it’s true for reading to some extend, the biggest bottleneck I experience is writing to the shared folder. This happens a lot with cache and logs in development mode when you use e.g. symfony2. These folders live inside the project dir and depending on your project structure you might not be able to redirect them to some folder inside the vm.

If you write your blog to also be found through Google, you may have a sitemap which makes it easy for Google and Bing to crawl your page. It might be good idea to inform both if this sitemap changes so they can send their crawlers your way and update their index with the great stuff you just put on their. This can be done by doing a
GET request and passing the url to your sitemap as a parameter. Easy as pie, right?

You know you should do backups, right? Taking all those data you store on your laptop and put it somewhere safe. There are so many ways of doing backups but people still don’t do regular backups. Maybe you put the data on an external drive and swear you’ll do this every month from now on. Chances are you’ll be to busy next month and the month after. And you still got a backup, right?

As you might know by now, I like static side generators. They combine the flexibility of a templating system with the easy deployment of static pages. Creating pages feels like working in a programming language and deploying the page in the end is as easy as putting some html files on an ftp (which you shouldn’t do, of course). There is no need for a complicated setup or deployment process because it’s just some HTML served from nginx (or any other webserver). You can put the files on Amazon S3, your own host or github pages. And as it’s only static files being served, performance is as good as it gets.

I wanted to do this for a long time. Write a “Hello World” on a new blog. So here it is. Awesome! But this is not a normal “Hello world” trying to get my feet wet, this is a post on why one should avoid blogging plattforms like Blogspot, where my blog lived up until now.
