Searching the Twitter database: MapD TweetMap

It’s no secret that Tweets contain a wealth of information and with the proper search algorithm, one can find very interesting patterns using the data. TweetMap, a prototype twitter search application allows you to search for the geographic and temporal distribution of words used in Tweets and visualizes them in a pretty decent map.


Searching Twitter

MapD, the startup behind the application TweetMap was interestingly born out of the necessity to speed up the process of finding patterns in tweets about Arab Spring.

The Mapd Tweetmap allows you to search for the geographical and temporal distribution of words used in Twitter messages around the world. The SF based startup’s tool allows anyone to query the Twitter database (between 1st Nov, 2014 and 28th Feb, 2015) for any hashtag (or word, but why would you really! its twitter after all) and visualise the results on the map. Whether you decide to use dot map or the choropleth map, I leave it up to the cartographer in you 😉

Another interesting aspect is the breakdown of the tweets according to the language used in the 140 character message.

The MapD TweetMap is definitely worth checking out, especially if you are a big fan of Twitter 🙂

What Happens If You Don’t Register Your Drone with the FAA?


Starting from Friday, February 19th all hobby drone owners in the US above 13 years old who own a device weighting between 0.55-50 pounds (0.25-22.5 kg) must be registered with the FAA. You haven’t done it yet and you’re wondering what problems you might face?

In theory the rules are quite strict. The civil penalties for not registering your device include a fine of up to $27,500. Criminal penalties include a fine of up to $250,000 and up to three years in jail. In practice you probably don’t have to worry about the FAA tracking down drown owners without a registration number. But if your drone gets caught up in some sort of incident and you are not registered you might face some stiff penalties.

You can compare it to driving without a valid driving licence. When you have it nothing will happen to you. One time you forget it you will surely be stopped by a police patrol. In fact there is no reason not to register your drone, and in the likelihood that something goes wrong, it’s definitely better to be safe than sorry.


FAA said that 342,000 drone owners have been registered to the database until the end of last week which is a half of estimated 1 million aircrafts sold in the US last year. So if you haven’t done it yet it is worth so spend $5 and register.
