Singapore - Catching Every Drop of Rain The source of the map of the rivers of Singapore is the Singapore PUB As a small island that doesn't have natural aquifers and lakes and with little land to collect rainwater, Singapore needs to maximize whatever it can harvest. Currently, Singapore uses two separate systems to collect rainwater and used water. Rainwater is collected through a comprehensive network of drains, canals, rivers and stormwater collection ponds before it is channelled to Singapore's 17 reservoirs for storage. This makes Singapore one of the few countries in the world to harvest urban stormwater on a large scale for its water supply. The newest reservoirs are Punggol and Serangoon Reservoirs which are our 16th and 17th reservoirs. By 2011, the water catchment area has increased from half to two-thirds of Singapore’s land surface with the completion of the Marina, Punggol and Serangoon reservoirs. With all the major estuaries already dammed to create reservoirs,

Advances in artificial intelligence: deep learning November 25, 2012 – 12:34 am If you want to keep up with advances in artificial intelligence, the  New York Times  has an essential article  on a recent step forward called  deep learning . There is a rule of thumb for following how AI is progressing: keep track of what  Geoffrey Hinton  is doing. Much of the current science of artificial neural networks and machine learning stems from his work or work he has done with collaborators. The New York Times  piece riffs on the fact that Hinton and his team just won a competition to design software to help find molecules that are most likely to be good candidates for new drugs. Hinton’s team entered late, their software didn’t include a big detailed database of prior knowledge, and they easily won by applying deep learning methods. To understand the advance you need to know a little about how modern AI works. Most uses abstract statistical representations. For example, a face recognition sys

Brick By Brick Chana Joffe-Walt  examines  Lego's dominance despite their products' high cost and lack of exclusive patent: Lego goes to great lengths to make its pieces really, really well, according to David Robertson, who is working on a book about Lego. Inside every Lego brick, there are three numbers, that identify exactly what mold the brick came from, and what position it was in in that mold. That way, if there's a bad brick somewhere, the company can go back and fix the mold. For decades this is what kept Lego ahead. It's actually pretty hard to make millions of plastic blocks that all fit together. Dreher recently  sang the praises  of the toy company. Tip, The Daily Dish
