Mobiles & crowdsourced weather measurement

pressureNETI shared this from The Economist quite some time back: Counting raindrops. Here is an example of folk using mobile phone networks themselves for weather forecasting. 

Today I stumbled upon Cumulonimbus. They have an Android application called pressureNET, which makes use of the barometer in some Android phones. This is user-contributed atmospheric pressure readings, embedded on a Google map. It is available to view at

It seems many devices have a barometer as well. Samsung leads the pack with the Galaxy S3, S4, Note, Note II, Galaxy Nexus. It also comes with the Nexus 4 & Nexus 10.

Crowdsourced Wikipedia & Google results

In times of “war”, Wikipedia can be used to sway Google results. Read: In Lahad Datu conflict, Google bombs & Wiki-wars. That’s pretty much what I tweeted yesterday. Just check out the revision history for Sabah.

Wikipedia tells an interesting tale. Even since 2005, you can see from the Talk page, that there have been Sulu sultanate claims. All in, just look at the traffic stats to the page and you see a marked increase in people wanting to know about Sabah.

The page is now semi-protected till March 14, but I doubt the standoff will be over by then, so expect Wikipedia editors to be paying close attention to this page. As for Google, there are benefits to getting the latest information from Wikipedia, but you’re also vulnerable when non-neutral points of view get displayed (thus making many people claim that Google was hacked!).

I checked DuckDuckGo and it seems that they use a much older cache of Wikipedia so was not affected by these Wikipedia changes.
