- Mesa: Geo-Replicated, Near Real-Time, Scalable Data Warehousing (PDF) — paper by Googlers on the database holding G’s ad data. Trillions of rows, petabytes of data, point queries with 99th percentile latency in the hundreds of milliseconds and overall query throughput of trillions of rows fetched per day, continuous updates on the order of millions of rows updated per second, strong consistency and repeatable query results even if a query involves multiple datacenters, and no SPOF.

- Thumbstopping (Salon) — The prime goal of a Facebook ad campaign is to create an ad “so compelling that it would get people to stop scrolling through their news feeds,” reports the Times. This is known, in Facebook land, as a “thumbstopper.” And thus, the great promise of the digitial revolution is realized: The best minds of our generation are obsessed with manipulating the movement of your thumb on a smartphone touch-screen.
- om3d — pose a model based on its occurrence in a photo, then update the photo after rotating and re-rendering the model. Research is doing some sweet things these days—this comes hot on the heels of recovering sounds from high-speed video of things like chip bags.
- Microsoft’s Development Practices (Ars Technica) — they get the devops religion but call it “combined engineering”. They get the idea of shared code bases, but call it “open source”. At least when they got the agile religion, they called it that. Check out the horror story of where they started: a two-year development process in which only about four months would be spent writing new code. Twice as long would be spent fixing that code. MSFT’s waterfall was the equivalent of American football, where there’s 11 minutes of actual play in the average 3h 12m game.
From tiny satellites to young programmers to reasoned paranoia, here are key talks from OSCON 2014.
Experts and advocates from across the open source world assembled in Portland, Ore. this week for OSCON 2014. Below you’ll find a handful of keynotes and interviews from the event that we found particularly notable.
