Four short links: 9 October 2015

Page Loads, Data Engines, Small Groups, and Political Misperception

  1. Ludicrously Fast Page Loads: A Guide for Full-Stack Devs (Nate Berkopec) — steps slowly through the steps of page loading using Chrome Developer Tools’ timeline. Very easy to follow.
  2. Specialised and Hybrid Data Management and Processing Engines (Ben Lorica) — wrap-up of data engines uncovered at Strata + Hadoop World NYC 2015.
  3. Power of Small Groups (Matt Webb) — Matt’s joined a small Slack community of like-minded friends. There’s a space where articles written or edited by members automatically show up. I like that. I caught myself thinking: it’d be nice to have Last.FM here, too, and Dopplr. Nothing that requires much effort. Let’s also pull in Instagram. Automatic stuff so I can see what people are doing, and people can see what I’m doing. Just for this group. Back to those original intentions. Ambient awareness, togetherness. cf Clay Shirky’s situated software. Everything useful from 2004 will be rebuilt once the fetish for scale passes.
  4. Asymmetric Misperceptions (PDF) — research into the systematic mismatch between how politicians think their constituents feel on issues, and how the constituents actually feel. Our findings underscore doubts that policymakers perceive opinion accurately: politicians maintain systematic misperceptions about constituents’ views, typically erring by over 10 percentage points, and entire groups of politicians maintain even more severe collective misperceptions. A second, post-election survey finds the electoral process fails to ameliorate these misperceptions.
