Feed: What's New. Author: Joshua Milligan. All of the Nest thermostat data I capture via the script is in a Google Sheet and I can directly connect to it with Tableau Prep (versions 2019.4 and newer)! The Tableau Flow itself looks a bit complex, but it’s mostly just the same steps duplicated for each measure: Each piece, like Inside Temps is primarily splitting the really, really long string: then pivoting so that all those measurements and times are together in a single column: And then doing some additional splitting out of the measure from the timestamp, parsing the date and ...

Feed: Actian. Author: Jack Mardack. It feels like only yesterday that “Machine Learning” and “Artificial Intelligence” were equated with science fiction by most regular folks outside of tech. As a movie-going culture, we have a long history of associating these concepts with self-aware robots or rogue computer programs that could escape the laboratories where they were created and threaten all humanity. But in 2020, ML and AI have been considerably demystified. And yet, even if it seems less likely now that the Singularity will be triggered by the reckless ambition of some tech startup, consumers have new reasons to be concerned. Yes, ML and AI are going mainstream, and it’s not just disruption-minded startups that are leveraging these technologies. Enterprises in a wide range of established industries are finding solid business reasons ... Read More
