                What's the correct query clause to get all the transactions from March on the east coast of the US? The correct answer is `"2012-03-01T05" <= eventTimestamp < "2012-04-01T04"`. Notice how the timeshift for the beginning of March is different from the end. Getting this right is mind bendingly difficult. This blog post and the Lumenize/tzTime libr…

Top 10 recommendations for developers

Update: tzTime (documentation) is now available seperately from Lumenize. The examples below still work because tzTime is a dependency of Lumenize and included in that package (as well as Rally's App SDK v2.0p6 or greater). However, Lumenize includes a lot more functionality around time-series and temporal model aggregations, OLAP Cube, etc. If you just want the Time object, just grab tzTime.
What's the correct query clause to get all the transactions from March? The naive answer is "2012-03-01" &lt;= eventTimestamp &lt;= "2012-03-31" but what if the person worked in the eastern US and wanted timezone taken into account? Then the correct answer is "2012-03-01T05" &lt;= eventTimestamp &lt; "2012-04-01T04". Notice how the timeshift for the beginning of March is different from the end.

    Assignment A: functions

We have a functions "module" that contains a number of functions. We want to add a sumCubes function. Start by looking at the code for functions.sum and functions.sumSquares. Go take a look at functions.sumSquares(). The code for sumCubes will be very similar but instead of summing the raw values (temp += v), or the square of the values (temp += v * v), this will sum the cube (temp += v * v * v). Note: temp += v is short hand for temp = temp + v.
Lumenize.functions are designed to incrementally calculate the results from prior results. Did you notice how that works? The trick is to understand that in CoffeeScript it is perfectly legal to call a function with less than the full list of parameters. So, if you call functions.sum([1, 2, 3, 4]) (only using the fist values parameter), the answer will be 10. However, let's say you previously calculated the sum for [1, 2, 3] = 6 and you wanted to take advantage of that prior calculation to speed up the calculation of sum of
