Shazam music recognition maps

Shazam is a service with an app that lets you point your phone towards some music to identify the name and artist of a song. For a hack day, Umar Hansa mapped a billion recognitions. Some of the maps color-code recognitions by iPhone and Android use which is kind of interesting. Hansa used Eric Fischer’s...

Algorithm to detect wildfires earlier

Traditional detection algorithms use infrared heat as the main signal of a wildfire. The Firelight Detection Algorithm uses visible light instead, detecting a fire possibly a day earlier. FILDA uses the visible light of fire, detecting high resolution images of fires. Using VIIRS technology, images of fires at night can be captured using infrared and...

Boost economy with immigration

Want to increase the GDP? Easy. Let more immigrants in. Lena Groeger for ProPublica: In an analysis for ProPublica, Adam Ozimek and Mark Zandi at Moody’s Analytics, an independent economics firm, estimated that for every 1 percent increase in U.S. population made of immigrants, GDP rises 1.15 percent. So a simple way to get to Trump’s 4 percent GDP bump? Take in about 8 million net immigrants per year. To...

Gender representation in comic books

Amanda Shendruk for The Pudding analyzed how genders are represented differently in comic books, focusing on “naming conventions, types of superpowers, and the composition of teams to see how male and female genders are portrayed.” The charts are good, but I’m pretty sure the animated GIFs for a handful of female characters make the piece.

Traditional detection algorithms use infrared heat as the main signal of a wildfire. The Firelight Detection Algorithm uses visible light instead, detecting a fire possibly a day earlier. FILDA uses the visible light of fire, detecting high resolution images of fires. Using VIIRS technology, images of fires at night can be captured using infrared and visible light information. FILDA can also detect 90% more pixels than previous methods, and can...

Reconstructing faces from brain waves

Researchers attached electrodes to neurons in monkeys, showed them pictures of faces, and then reconstructed the faces reading brain waves. After decades of work, scientists at Caltech may have finally cracked our brain’s facial recognition code. Using brain scans and direct neuron recording from macaque monkeys, the team found specialized “face patches” that respond to specific combinations of facial features. Like dials on a music mixer, each patch is fine-tuned...

This one takes time to make, takes even more time to read

Reader Matt F. contributed this confusing chart from Wired, accompanying an article about Netflix viewing behavior.  Matt doesn't like this chart. He thinks the main insight - most viewers drop out after the first episode - is too obvious. And there are more reasons why the chart doesn't work. This is an example of a high-effort, low-reward chart. See my return-on-effort matrix for more on this subject. The high effort...

Detailed satellite view of iceberg break

Using the thermal signature, NASA provides a detailed view of the break: The false-color image was captured by Landsat’s Thermal Infrared Sensor (TIRS). It shows the relative warmth or coolness of the landscape. Orange indicates where the surface is the warmest, most notably the mélange between the new berg and the ice shelf. Light blues and whites are the coldest areas, including the ice shelf and the iceberg. It’s like...

Hidden oil patterns on bowling lanes

This explainer video by Vox on the oil patterns on bowling lanes was oddly fascinating. The varying degrees of oil can change a professional bowler’s strategy as a tournament progresses. I kind of want to be a professional bowler now. This whole data thing is probably a fad anyways. Tags: bowling, sports, Vox
