Premise Data General How many countries do you operate? We’re currently in more than 30 countries across six continents. How do you decide which countries you’ll start a network in next? These decisions are generally customer-driven depending on their data needs. Harvey vs Katrina: Have New Orleans lessons been learned? Image copyright AFP Scenes of vulnerable people in Houston trapped in rapidly rising floodwaters are evoking memories of the 2005 Hurricane Katrina disaster in which nearly 2,000 people died. The US government response to Katrina is widely seen as an abject failure that saw poorer, mainly black residents abandoned to fend for themselves.

Questionnaire design Perhaps the most important part of the survey process is the creation of questions that accurately measure the opinions, experiences and behaviors of the public. Accurate random sampling and high response rates will be wasted if the information gathered is built on a shaky foundation of ambiguous or biased questions. Creating good measures involves both writing good questions and organizing them to form the questionnaire. Questionnaire design is a multistage process that requires attention to many details at once. The Sea Level Around Florida Is Rising Six Times Faster Than Average It really is hard to overstate how screwed Florida is when it comes to climate change. Sea level rise has already ensured that floods are becoming common, not freak weather extremes; it’s guaranteeing that hurricanes and their associated storm surges are just getting that much more powerful. Despite all this evidence, however, Governors and Senators who are often climate change deniers still get voted back into power there. As a result, instead of investing in climate change prevention measures, streets in Miami are literally getting raised up off the ground to stop floodwater coming in. A new study, published in Geophysical Research Letters, suggests that even this ludicrously short-sighted measure won’t be enough to stop the incoming tide. Sea level rise around the globe is accelerating year-on-year, but along the Floridian coastline, it’s rising up three to six times faster than average.
Greenland Fires Ignite Climate Change Fears In a real clash of fire and ice, a massive wildfire in southern Greenland has captured the world’s attention. At the end of July, a couple of NASA satellites detected hot spots in Greenland that indicated fire, said Mark Ruminski, a team leader for a hazard mapping system of the National Oceanic and Atmospheric Administration. But fires are unexpected in Greenland, so he and his team thought it might be an error in the data. Then a civilian pilot snapped pictures of a wildfire near Sisimiut, the second-largest city in Greenland. When clouds cleared a few days later, NASA’s Landsat 8 satellite and the European Space Agency’s Sentinel-2 satellites captured photos of the largest of the fires from high above.
Interview with Rick Smolan on ‘The Human Face of Big Data’ Manu: Rick, can you tell us a bit about yourself? I saw in your TED talk that you used to be a photo journalist, so how did you get started on this journey? Rick Smolan: Yes, I was always very curious as a person so it’s interesting that I’d end up in a job where I get paid to be curious. As you saw in the TED talk, I went from being a journalist where I work for other people who set the agenda, to the fortunate position of being able to steer my own ship. And now, when I get curious about something I’m able to invite my heroes, my peers and some young journalists along.
Planners turn rising seas into game » Yale Climate Connections Imagine it’s the year 2050, and you’re the city planner of an island that’s threatened by sea-level rise and storms. That’s the scenario in “Game of Floods,” a board game in which students and community members confront these real climate change risks. Pretend you're the city planner of an island that's threatened by #sealevelrise and storms. Click To Tweet Westhoff: “We are particularly excited about bringing it to schools as we feel that it’s critical that the youth of today understand this challenge that they’re faced with.” That’s Alex Westhoff, with the Marin County Community Development Agency in California, which developed the game.
Redshift Performance & Cost At Airbnb, we look into all possible ways to improve our product and user experience. Often times this involves lots of analytics behind the scene. Our data pipeline thus far has consisted of Hadoop, MySQL, R and Stata. We’ve used a wide variety of libraries for interfacing with our Hadoop cluster such as Hive, Pig, Cascading and Cascalog. Melting glaciers in Swiss Alps could reveal hundreds of mummified corpses Swiss police say hundreds of bodies of mountaineers who have gone missing in the Alps in the past century could emerge in coming years as global warming forces the country’s glaciers to retreat. Alpine authorities have registered a significant increase in the number of human remains discovered last month, with the body of a man missing for 30 years the most recent to be uncovered. Rescue teams in Saas Valley in the Valais canton were called last Tuesday after two climbers retreating from an aborted ascent spotted a hand and two shoes protruding from the Hohlaub glacier. Rescuers spent two hours freeing the mummified body with icepicks and their bare hands, also recovering a silver wristwatch and a ring.
SQL Language for management and use of relational databases SQL ( S-Q-L, "sequel"; Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). It is particularly useful in handling structured data, i.e. data incorporating relations among entities and variables. SQL offers two main advantages over older read–write APIs such as ISAM or VSAM.
Short Answers to Hard Questions About Climate Change - The New York Times 3. Is there anything I can do about climate change? Fly less, drive less, waste less.
