Staff Picks

This week we have more staff picks than the last, a testament to the increase in quality of contributions on Utopian.io. Highly useful bug reports are featured, some of which helped improve the overall interaction with our blockchain, Steem. We also received interesting and informative tutorials and documentation.

Particle physics @ Utopian - Detecting particles at colliders and implementing this on a computer by @lemouth [Blogs]

This contribution is the start of a collaboration between open source developers and computational physicists within cutting-edge particle physics experiments from CERN. MadAnalysis is the analysis framework of the project that allows open source developers to take part in the analysis of data from collisions in the Large Hadron Collider.

The contribution is an introductive post to what needs to be known, what the concept is, what is being done, and how to start collaborating. It is perfectly structured to provide all the required background knowledge for the exercise at the end, with useful links to external sources for further reading about the process. It also has high readability with its excellent presentation and formatting.

Steem-Python 1.0.1 Does Not Properly Handle Steemd Websocket Server Errors by @learnelectronics [Bug Hunting]


@learnelectronics identified a bug when instantiating an instance of Steem using an address to a websocket server that is currently generating server errors. In that case, Steem produces unpredictable behavior and exceptions that cannot be handled in a meaningful manner.

The bug report is detailed, with useful logs and accurate steps to reproduce, and also includes temporary workarounds. Overall, this represents a thorough work with the high quality standards we support on Utopian.io.

Beem: account.history_reverse() may fail with TypeError and Beem: Race condition in blockchain.blocks() when using threads by @stmdev [Bug Hunting]

Both these bug reports by @stmdev detail two different bugs found in Beem, a python library to interact with the Steem blockchain. These are a true example of the true potential of bug-hunting, where a problem identified by one developer leads to shared information, that benefits other related projects. A fine show of the power of Open Source: strength in shared knowledge.

By composition, these reports contain great insights into the nature of the problems, how they can be reproduced and ways to mitigate. These contributions shine in regards to bug-hunting as a whole.
