This is the most interesting question. And failsafe. You couldn't rely on this, unless there was a way to ensure it is working or had a fixed lifespan.
I believe the thermoelectric converter works by exploiting a temperature gradient, which I suspect would not be sufficient at this scale and location.
I've seen nodemon before and this is what worried me the most:
"nodemon has three potential methods it uses to look for file changes. First, it polls using the find command to search for files modified within the last second. This method works on systems with a BSD based find (Mac, for example)."
Especially on Mac OSX why would you prefer to use an external command like find instead of using Kqueue? I wonder if find is the right tool for that. And I wonder again why only on BSD-based systems when linux also has find.
Or, if you're on OSX using fswatch[1] or on linux inotifywatch[2] along with a simple shell script which kills and restarts your server. Crude, but gets the job done..
I don't understand why they don't just charge accounts with more than X followers. High profile brands are (currently) getting a massive amount of free advertising. I'm sure they would be willing to pay to keep up their profile.
See Mailchimp, free up to 2k subscribers, paid after that. It's so simple.
IIRC it's because they can't just attach an extra IP to their load balancers for each SSL site, since Amazon doesn't allow you to attach multiple elastic ips to one instance. So, they need to use an elastic load balancer for each site, which costs $18 per month + bandwidth. So they are probably actually just breaking even or losing money on that $20/month fee.
CBC has this story and they mention it's zenon isotopes that are measured to determine the age of the water.
>The researchers estimated how old the water was based on an analysis of the xenon gas dissolved in it. Like many other elements, xenon comes in forms with different masses, known as isotopes. The water in the Timmins mine contained an unusually high level of lighter isotopes of xenon that are thought to have come from the Earth's atmosphere at the time it became trapped.
Both Cloudmade and MapBox use OpenStreetMap data. Leaflet ( http://leafletjs.com/ ) was created by Cloudmade and is the JavaScript lib for putting tiled maps on the web. Mapbox have their own version of Leaflet, but it's essentially much the same if all you want to do it drop pins, work with layers, choose a tile set.
Both are comparable, and both are strong in the same space: Custom styled, tiled maps. And both are weak in the same place: routing.
Not to say that they don't do routing, but it's certainly not their forte.
Thankfully the majority use-case for most sites and applications using maps is simply "show a map, drop a few pins here and there". So having this map look and feel like the site is actually a good selling point.
That's surprisingly good. As in; for a complex route across London and factoring in one-way streets it produces something that looks realistic.
Only allowed me to pick car as a mode of transport, and unrealistically suggested I could get across 14KM of central London in 14 mins, but ignoring those things this is very nice.
Would love to see the path output of this added to Leaflet and a standard form of API emerge for Mapbox, Cloudmade, Google Maps, etc.
I believe that other transport modes (public transport, on foot) are in the pipeline, but the amount of additional compute power they need is significant
Also Public Transport route and connectivity information is frequently a bit patchy in OSM, but this is steadily improving.
You should look into OpenTripPlanner by OpenPlans, they have built a multi-modal routing engine that can account for GTFS public data feeds as well as combining walking/cycling/public transit together to for a single route.
