There was an unintentional fork on August 15, 2010, when "[an] attacker exploited [an] integer overflow bug that permitted an attacker to create several billion bitcoins". [source][0]

There was an unintentional fork on March 12, 2013 caused by previously disallowed number of tx inputs (?) as resolved by [BIP50][1].

UI suggestion: Instead of showing a list of things, just put them on the map

There are a few projects working on this. One problem is key management and giving the app a connection to the blockchain. If you do key management in the webapp and read from the blockchain via a centralized API, thats not much of an improvement over existing systems. Ethereum core's solution to this is a special browser, but it is still under development. I'm working on a project[0] that takes this on, but is still a couple months out from a public beta. Its a bit of a hack but it manages a zero-install solution by having a sort of browser-in-browser that intercepts transaction signing requests and provides access to blockchain data. Can't wait to get it out there.

Gitlab as id/auth provider, eh? What is out there in terms of id/auth appliances that are sufficiently generic/cross-platform?

names are hard, but i implore you to continue your search

so are you guys like an incubator for decentralized apps?

here's a JS implementation of Bret Victor's "Learnable Programming" demo http://www.fullstack.io/choc/

Colored coins are a clever hack. Newer blockchains like Ethereum[0] are designed to have yet-unthought-of things built on top of them.

It doesn't in v8 -- what do you mean by `should`?

Relevant code if someone wants to audit: https://github.com/ethereum/go-ethereum/blob/4df2e1ef5c20ebd...

As a comparison, worth noting that the watch does not have GPS without the paired phone. So if you wanted to go out for a run and track the course, you would need to bring the phone.

Just because its a decentralized system, does not mean the problem is best solved with a blockchain. It is but one tool in the toolbox.

The above calculation was for 32bpp:

3 colors * 1 byte * (8 bits/byte) = 32 bits

If I were to throw a js one together, I would use these as a starting point:

If I were building a giant battery factory, I would also encourage others to make electric cars.

a source of some confusion: zerocoin !== zerocash

I've worked on a project that used Blockly and found it to be great : )

Shouldn't we name names in this case? This behaviour should be part of the company's public image. Or does that just greatly increase the legal risk for the author?

"Seven percent of the test group could bitshift"

define 'reality'

use webrtc, easy. then you wont even need your own backend.

plz enable github issues

If you haven't seen it yet, checkout this value and time scrubber, a pretty faithful recreation of Bret Victor's demo http://www.fullstack.io/choc/

"sell the sizzle not the steak"

im saying it would be trivial to implement LOGO in choc

I work on various open-source learnable programming projects and would like to make myself available to provide support for your lesson plans involving choc. aaron [at] kumavis.me

you're seeing the tree and missing the forest -- this isnt about the examples its about the technology they feature. write a LOGO turtle example, then you can scrub its instructions, and execution

Yerba Buena. Where are all these states you guys are talking about? I don't see them on the map...
