Tool of the week : Camtasia from Techsmith

When you are doing conferences and presentations to other people, you need a great tool to capture your screens and voice. I tried a lot of softwares, most of them are free and/or open source but no one give me exactly what I was looking for : a light footprint when operating screen capture (it’s a mess when your system slow down just cause you are screencasting), powerful in terms of features and options to capture your work, with a real editor and bug free (not crashing during working and wasting your time) ! I' don’t have a big expectation but a lots of softwares just deceive me, that’s why I wasn’t able to share my presentations from the last Docker meetup.

Being an MVP is a cool thing : you can share with a lot of people, sharing your tools and knowledges. During a conversation with a buddy of mine, he recommends me the ONE tool you need for your next presentations ! From years now, Techsmith is providing Camtasia to professionals and I decided to try it ! I can just truely recommend you to give it a try here : and share your next presentations.

Share your passion with Camtasia !

Maven Docker build failed with ‘org.apache.http.conn.HttpHostConnectException: Connect to localhost:2375’ on Windows

You can have this kind of error when building a project with Maven and the Docker plugin (by Spotify) :

On Windows, with Docker for Windows, just check if you have exposed the daemon on port 2375 (in Docker for Windows settings) :


And your Maven build should create the Docker image.
