    I'll be speaking at about a streamlined workflow for tidy time series analysis using tsibble and fable. A warm-up post to provide an overview of tsibble with a case study of NYC Citi bike data.

    If Trump actually did shoot someone on Fifth Avenue, the headline would be “In midtown violence, echoes of a campaign boast”

    NYT reporters are under a Cassandra-like curse where they get amazing scoops but have to hide it behind vaguely dramatic headlines

    This is not the main point but it is amazing that the NYT hed for "Facebook let Netflix and Spotify spy on your DMs" is "As Facebook Raised a Privacy Wall, It Carved an Opening for Tech Giants"

    🦕 My latest weekend project is a game to guess which tweets are from Kanye and which are from Elon. ➡️ 😜 It’s harder than it sounds. 🎉 Good luck.

    “There’s already 20 million people who can build software - isn’t that enough?” No. Until making your own software is as accessible as writing your own book, we’re not there yet. Not everyone can (or wants to) write a great book, but most have the baseline skills to try.

    "You'll have plenty of time to get kidnapped after your manuscript is submitted"

    A Swedish-Iraqi student was rescued from an ISIS held town sometime in 2014 by mercenaries in four SUV’s hired by his thesis advisor and we’re only just hearing about it. 😬

    In the orientation for my PhD program, a professor recommended a biology class, but added “It’s probably too hard for someone whose background is, say, statistics.” I was the only stats major in the program, which he knew. He did not like me

    Tweet your favorite diss while in grad school. Mine: I went to my mathematical logic professor for help understanding the proof of a complicated theorem. He replied: “Don’t feel bad, Scott. Even talented students have problems with this.”

    Here's an alternative solution to the problem that's much less readable but fits in a tweet: mean(replicate(1e5, all(between(cumsum(rbinom(10, 1, rep(c(.5, .4), 5)) * rep(c(-1, 1), 5)), -2, 1)))) only non-base function is dplyr's between()
