In this month, I want to share all the blog posts, articles and links that I find interesting or helped me in my professional life. Disclaimer: I didn’t consume all of them.

Technology

Docker

Docker is a new approach for managing virtualized environments. Instead of booting a full blown VM, which takes a long time, Docker isolates the processes via Linux container images, which is really fast.

Very nice online tutorial. Just try it out in the browser.

Docker Containers

This article on Infoq made me look into Docker, actually.

Dokku is a real easy combination of FOSS, to replicate the deploy mechanism of Heroku. That means, you just push a git repository and a Docker image of your application will be built and run.

Shipyard

Docker web ui for managing docker images. Not tried out yet.

Scala FOSS Webapps

Scala becoming more and more popular. I found great web apps that should be easily deployable to Java servers.

Gitbucket

A FOSS Github/Gitlab alternative. Even as a seasoned Ruby developer, deploying and maintaining (that means upgrading every other month) of Gitlab can be a bit of a hassle.

PostgreSQL Studio

In comparison to MySQL, PostgreSQL is missing an ubiquitous web-based management software. PostgreSQL Studio could fill this gap.

Programming languages & Guides

A rolling stone gathers no moss.

Martin Odersky, the creator of Scala, and a very patient and clear teacher, gives the follow-up course of the Functional Programming with Scala course: Reactive Programming Principles. It will start on Nov 7th. Really looking forward!

Very brief overview over the language elements.

Presentation: Confessions of a Ruby Developer Whose Heart Was Stolen by Scala

In this talk my goal will be to illustrate how I've made the transition from the dynamic programming world of Ruby to the type safe and highly async/concurrent world of Scala and Akka. [...]. I want to illustrate how Scala does a much better job at allowing the developer to be expressive while avoiding common pitfalls with Ruby.

Just bought the beta-ebook, to peek into other webframeworks: client and server side: Sinatra, CanJS, AngularJS, Ring, Webmachine, Yesod, Immutant

Ruby/Rails specific

Various

Last but not least some articles, mostly unrelated to (my daily) programming.

Deadweight is a CSS coverage tool. Given a set of stylesheets and a set of URLs, it determines which selectors are actually used and reports which can be "safely" deleted.

Do not rely on your employer. A commercial company has no loyalty towards it’s employees, so you should also have only limited to them. Instead, build upon your professional network and your personal skills. Discussed on Ruby Rogues.

'Spotify' for ebooks

Paying 10 bucks a month and gain access to 10,000 ebooks. It’s about time!

Unfortunatly, only available in US atm. (Via German T3n)

Readmill

After buying 7 webframeworks in 7 weeks (as mentioned above), I was curious about the Readmill button, that Pragprog provides.

Readmill is a Berlin based startup, which provides synchronized beautiful reading apps. So far, I like it, and imported some of my epubs. Unfortunatly, the Android app still needs work (no text highlighting, synchronizing is broken) and there is no web interface for reading.
