That is fun. A bit scary, but fun.

A pause button would be nice. Also, parts of Australia light up with activity on the map, but strangely it isn't listed on the dashboard.

I believe the regions are defined as the blocks that become visible when you hover over the content title. The Asia one doesn't include Australia.

It's only on geolocated tweets ! Awesome.
pax
that means the less popular locations get even less exposure, as there are plenty of places in the less developed world of which Twitter location (desktop) is unaware of.

Is it just me, or is it ironic that this site is currently unavailable?
dangrossman
It's just you. What does visualizing tweets have to do with high availability?

would be nice to have a website for "tweetping traffic in real time(as it gets hit by HN)"

the author is working on it, more you are, more he will improve perf.

How are they getting the data? Twitter's APIs seem so limited these days.
FranckErnewein
Data come from the Twitter Streaming API https://dev.twitter.com/docs/streaming-apis

Is the site getting the firehose stream though? How do you get that level of access?
huskyr
They're probably using the 'sample' firehose, which is not protected and still serves a few tweets per second.
tariqr
that looks like a lot more data than a few tweets per second though.

It struck me seeing this how rare it is now to see any kind of Twitter experiment. Complete 180 from a few years back.

There's so much potential information there, and some very neat things you can do with it. But for me at least, their new API policies completely turned me off of making cool things with it. Not that the API isn't still powerful.

Yep. I was part of the Web Ecology Project in 2009-2010 and we were able to get pretty awesome access to Twitter at the time. I had a good dialog on a weekly basis it seemed with their API team and they were super responsive and supportive of us. Although, whenever I asked what we needed to pay for full Firehose (which some companies were getting) I couldn't get an answer from them, and I think they only wanted to talk with huge companies.

Then that all stopped. No more whitelisted IPs for search, no more new whitelisted accounts for API calls, and then they stripped all my whitelisted accounts of their 20k/hr API calls and put them all back at the standard 150/hr or whatever.

And what's worse is the network is bigger than ever. Instead of scaling API access up with network size, they scaled it down. This is really a shame as I think Twitter is terribly interesting to with it from an academic standpoint, but unless you have huge money to shell out for API calls or direct access you're screwed.

This is pretty awesome, but I would like to be able to dig in deeper. After looking at it for a couple minutes, there's really nothing more I can do.
lampe
nice work!

iam love twitter and right now iam watching a show called #domian and iam looking for that hashtag and there are per minute about 30 tweets and i dont see them on your site. iam from germany.

or did i just overlooked something?

This was really cool. The office is having internet connectivity problems right now, and after we fixed it, this page loaded, and for a brief moment, I felt like a hacker from the movies :D
bhauer
Very cool! Mind providing some background on how you've rendered the world map and determine tweet coordinates? Are you mapping the tweets' latitude and longitude through some projection formula?
hijinks
Ya I'd like to know also
pzeups
It's only geolocated tweets. No projection, just a render with Nodejs w/ Socket.io, Processing.js and Backbone.js !

I'm surprised at the amount of traffic coming from Indonesia. Can anyone offer some insight?
pax
Indonesia has 4th biggest population in the world. Also, 6th most active country on Twitter (2010).

Incredibly well done and excellent execution. However, there is a noticeable delay/lag that totally took me out of the user experience. Even though the concept was really cool, I wouldn't mind if everything was slowed down a bit so I get what's actually going on and there was a bit less lag.

what? no link to the github repo?

I just realized that they don't have twitter in Australia!! ;)

I think europa should be europe, for correctness's sake

Nice. I like trendsmap as well. www.trendsmap.com

Curious about the CPU usage of canvas apps on older systems, I ran this in FF and Chrome. (I'd classify the system I'm on at the moment as a mid-tier business PC from 2008.) FF maintained a CPU usage mostly in the 33-40% range and Chrome in the 18-23% range. CPU usage would spike up to 75-90% in FF, whereas the largest spike in Chrome was only 40%.

It's just one data point, but I was impressed with how much more efficient Chrome was than FF.

Sites Down - I'm upset I was trying to show this around.

Are you sure? the webpage showed me these:
