10:45 AM PDT We are investigating increased error rates for ElasticSearch clusters in the US-EAST-1 Region.

Multiple clusters unreachable

Great idea! This is open source so anyone can play with it

TBT: d3/leaflet combination that renders geoJSON tiles http://bl.ocks.org/ZJONSSON/5529395 (still operational)

For 200+ labels you can check out the force_labels in d3-plugins, https://github.com/d3/d3-plugins/tree/master/force_labels. Demo: http://bl.ocks.org/zjonsson/1691430

If you look more closely at the actual code, this exercise compares the performance of readFileSync (an operation that deliberately blocks) on 1 core vs 2 cores.

Few minutes ago it said: 'Page unable to load as internal error occurred'. Straight and clear to the point! ..now the page doesn't respond.

Initially they overlap which is one of the main cause of the jitter. Spreading out the initial locations would be a remedy, but then I would have to find a different way to explain "diffusion" to my daughter :)

Brilliant, thank you! My initial approach was simplistic (to avoid combinatory explosion) but prime numbers seem obvious in hindsight!

This works as well (using jquery): var a=0,t;setInterval(function(){t=$("#question").text().replace('x','*').replace('÷','/');t=t.slice(0,t.length-2);if(t!=a)$("#answer").val(eval(t)).keyup();a=t;},0);

There is a link to the source at the bottom of the page (http://www.straeto.is/rauntimakort/). I parse the JSON input, associate the records with previous ones (i.e. which bus is uniquely which) and stream output via websockets.
