- Loading Data using R and PowerBI by Nick Burns at SQLServerCentral
Nick explains why he isn't a fan of Power BI's R visuals. But the alternative is loading data via an R script and display it in a native Power BI visual. I specially liked his neat technique of unpivoting data with R to end up with a key-value pair. This gives him the possibility to easily slice the final scatterplot by the keys of the key-value pair, which were the attributes (columns) in the original data set before the unpivot action. - Configuring “all” access with dynamic row-level security by Daniil Maslyuk (@DMaslyuk | xxlbi.com)
Daniil has a nice solution for solving a problem with dynamic RLS for a security table with 2 attributes, e.g. Department and Region where several users have "ALL" configured for 1 or 2 attributes. For example, the CEO can see all departments and regions, but the CFO can see all regions but only the Finance department. He introduces an unrelated UserSecurity table and filters the facts and dimensions by this table. - Epic Life Quest Task: Setting the Summit Pre-Con Attendance Record by Brent Ozar (@BrentO | Ozar.me)
Brent and Erik put themselves to the test and passed gloriously: they sold out all the 360 seats in their pre-con. Brent gives a look behind the scenes how they pulled it off and what they did to get it sold out: write a blog post, online presentation, email announcements and give more value to the attendees with stretch goals. - A Freecon Halloween at the PASS Summit at SQLServerCentral
