I've had the pleasure of playing around with kit for a few months, and it's really addicting. I find myself spending a lot more time than I thought I would putting together kits. Here's one I made last night: http://kit.com/trevorkmarshall/nerd-battlestation. Congrats to the kit team!
I'm probably the only one doing it outside a bank or hedge fund, but since kdb+ opened up their 32-bit license for free, it's been amazing working with. Log files and splayed tables are stored neatly on disk so backing up to aws nightly is a breeze. It is a great solution for high tick rate logging of homogeneous data, especially when that data needs to be highly available in business applications.
This is fantastic, I can't wait to see who emerges as the first lightning network payment channel provider. This helps alleviate fundamental issues with the current implementation of Bitcoin without the need for a hardfork, and could even be a solution to the wallet identification issue if the payment channel provider acts as domain name registry. ie instead of accepting transactions to an ugly string I could accept transactions to ntq.blockchain.info.
I'd love to see a quick way to copy the URL of the page you're on, since I more often text people links rather than email them, and "Share via iMessage" doesn't seem to be implemented yet
