Last week it happened again. Geek2Geek! This time we came together at Flyeralarm in Berlin to talk about centralized logging. That is an interesting topic for all companies which have to scale.

Configuring host and port for Selenium/Capybara

I’m using Capybara and Selenium together with RSpec to test the Web Interface for VersionEye. That works very well. For an integration test I needed a callback on localhost:3000/auth/*. By Default Capybara is starting the tests on an odd host and port name to avoid conflicts with locahost:3000, which is the default host and portContinue reading “Configuring host and port for Selenium/Capybara”

has_secure_password with Rails 4.1

I just started a new project with Rails 4.1 and explored the has_secure_password feature. Really awesome stuff! I hope you are not storing passwords in clear text to your database! You should always store some kind of hashed values instead of clear text passwords. In case somebody steals your database he/she still doesn’t has theContinue reading “has_secure_password with Rails 4.1”

Comparison of Application Level Package Managers

I have to work with a lot (9) of different package managers at my daily work at VersionEye. Part of our mission is it to make manual updating of dependencies extinct, because it’s a manual and time consuming task which nobody enjoys. That’s why we are building a notification system for open source software libraries to make ContinuousContinue reading “Comparison of Application Level Package Managers”

Semantic Versioning

Do you know semantic versioning? You should! It describes how to name version numbers. Check it out here: semver.org. This is the pattern it describes: MAJOR.MINOR.PATCH MAJOR version when you make incompatible API changes  MINOR version when you add functionality in a backwards-compatible manner PATCH version when you make backwards-compatible bug fixes The cool thing hereContinue reading “Semantic Versioning”

Muted versions

We just launched the “muted” feature a couple days ago. A highly requested feature from the VersionEye community. This is how it works. Let’s say you have a couple out-dated dependencies in your project. For example jquery-rails: For some reason you don’t want to use the current version 3.0.4. But VersionEye keeps telling you thatContinue reading “Muted versions”
