Release 0.2, Third PR

-
This week I was contributing to an open source project called Marquez. It is a metadata service for the collection, aggregation, and visualization of a data ecosystem's metadata. It also maintains the provenance of how datasets are consumed and produced, provides global visibility into kob runtime and frequency of dataset access, centralization of dataset lifecycle management, and much more. 

 The technologies this project uses are the following:
  • Java 8+
  • PostgreSQL 9.6 
For my third PR I picked an issue some of the classes that are used throughout the code. So I was looking for all occurrences of those replacing them with a new name. After creating a branch and making my changes I made sure that all tests pass locally using ./gradlew test command. Another important thing before pushing my changes and creating a pull request was to check if all .java files are formatted properly. I did that using ./gradlew spotlessJavaCheck command and noticed that a bunch of tests is failing because I forgot to alphabetically sort imports, so I ran ./gradlew spotlessApply in order to fix my mistakes.

fs.rmdir() vs fs.rmdirSync() in Node.js

-
The main purpose of rmdir() and rmdirSync() methods in the fs module is to remove a directory. If you are going to use any of these two methods, you should also remember that using them it is only possible to remove an empty directory. In case your goal is to get rid of the folder which contains another files or directories you would need to install the additional fs-extra module that would add more features on top of the fs. You can use remove() method from the fs-extra module to delete directories that contain something. fs.rmdir(path, callback) Removes a directory asynchronously. If the directory isn’t empty the function will throw an exception. Passed Parameters: path – string, path to the directory which you want to remove. The function won’t work if you will pass a path to the file instead of the directory (will result in ENOENT error on Windows and an ENOTDIR error on POSIX) callback – function, returns an error. Source code:  function rmdir(path, callback

Release 0.4, Second Blog

-
For my final release, I decided to stick with the project that I already worked on called Vibranium .  The ticket was to create a page pre-loader similar to the one that git-hub or medium websites use.  I never worked with animation in CSS before, so this issue was a great opportunity to learn something new. Steps to create an animation: The first step of building a CSS animation is to defining individual keyframes and naming an animation with a keyframes declaration. The second step is referencing the keyframes by name using the  animation-name  property as well as adding  animation-duration  and other optional animation properties to control the animation's behavior. Here's how I created a spinning square animation using keyframes in css: @-moz-keyframes spin { from { -moz-transform: rotate(0deg); } to { -moz-transform: rotate(360deg); } } @-webkit-keyframes spin { from { -webkit-transform: rotate(0deg); } to { -webkit-transform: rotate(360deg); } }

Release 0.3, Update 1

-
For the third release, I was looking into a bunch of different tickets, but it turned out to be quite hard to find a good one. Some of the tickets I found were still open, but already fixed in the code, others required more info to start working on them, and I couldn't get any response from the team. For now, I ended up looking into Marquez  project. It has a lot of nice tickets, but I'm still having troubles to get it working on my machine. Other tickets that I consider working on are: https://github.com/natlas/natlas/issues/113 https://github.com/Marko-Doornbos/tournament-site/issues/12 https://github.com/ICT4Dat/ict4dat-news-android/issues/159
