GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Testing with GoMock: A Tutorial

08/16/17 by  Sergey Grebenshchikov

No Comments

This is a quick tutorial on how to test code using the GoMock mocking library and the standard library testing package testing.

GoMock is a mock framework for Go. It enjoys a somewhat official status as part of the github.com/golang organization, integrates well with the built-in testing package, and provides a flexible expectation API.

// We want to create hideTabooValues, a Spark UDF that set to -1 fields that contains any of given taboo values.
// E.g. forbiddenValues = [1, 2, 3]
//      dataframe = [1, 2, 3, 4, 5, 6]
//      dataframe.select(hideTabooValues(forbiddenValues)) :> [-1, -1, -1, 4, 5, 6]
//
// Implementing this in Spark, we find two major issues:
