there's a surprising variety of tools available, and they each accomplish different things. for example: mixpanel and kissmetrics are great for tracking custom events and learning deeply about engagement and conversion inside your app. but

hey we don't support it yet, but we've gotten a couple requests for this, so we'll be looking into it soon!

the server side libraries hit our servers and then forward to the specific analytics services. the client side library (free) does not hit our servers and just forwards directly to each service.

hold up -- you are confusing molten salt with liquid metal. molten salt reactors do not contain liquid sodium metal. in a molten salt the sodium is chemically bound to Fluorine or Chlorine, etc. the explosive fire danger you're talking abou

thanks for the correction on china, will update!

well -- it's complicated. i started building a javascript library (nuclear.js : https://github.com/reinpk/nuclear.js ) to calculate the decay chains... the problem is that short lived isotopes, which are dangerous, can decay into long-live

could you outline the problems with thorium reactors that you know of? i've been searching high and low to figure out what they are. obviously they exist, but they often seem brushed over and ill-defined. any extra light you can shed on it

seems pretty good, but my first test found a potted plant in the aeroplane demo picture -- a 100 story potted plant :P very cool idea, super hard problem so mad respect regardless!

mmmm, yes quite inaccurate on my part. apologies. of course... uranium fission was a critical part of the hydrogen bomb ;) will correct that thanks.

the initial research being for weapons is probably part of it, though uranium-233 (from thorium) was used during a 1955 nuclear bomb test. [1] thorium reactors are also "breeder" reactors. they initially require an external source of neut

by pkrein 14y ago
as far i understand, yes. the real nasty thing about uranium-232 is that it emits highly dangerous gamma radiation [1], which is extremely unhealthy==difficult==expensive to handle. if i understand correctly, the gamma radiation also makes

by pkrein 14y ago
yes. a recent nature article pointed out how thorium can be used to make uranium-233 which can be used to make nuclear weapons.[1] (see the conclusions section at the end of the article) here's a more detailed explanation: the "old" idea be

LFTR are a type of molten salt reactor, which is mentioned, though certainly not given enough attention in this first short article ;) will see what i can do.

It's actually a bit hard to quantify. The true cost of radioactive waste is related to what type of radiation it emits (gamma? alpha particles?), how long-lived the radiation is i.e. it's half-life, and the actual quantity of that material

I'm a paid user of WorkFlowy, love it. The hash tags and @person references are really useful for working on shared workflowys. What we really need next though, is a way to transform the nested "mind map" (which is useful for getting stuff

It seems like high school & college girls would go bananas for this. They'd get to peruse clothes all day and try to make money? The right in on Facebook or Twitter seems like it would go a long ways.

true [backs up data]. the system will also auto-recover by falling back to the RT/YT/YQL APIs if someone does that, though pages will load significantly slower and Rotten Tomatoes will throw a bunch of rate-limiting errors until Firebase is

That's a cool idea, Dropbox and S3 both seem like good ways to get started with Firebase really fast. The AWS micro is free :) and it gives me a bit more flexibility to do things (in the future) like track outbound clicks to Fandango throug
