Yes it would make them susceptible...if, like Lavabit, they actually held private keys that secured your communications. They don't. While I have the utmost admiration for Levison's stand, the fact that Lavabit held centralized pr

I've cheered Ubiquiti's wireless hardware in the past on here [1], but I have to agree with you. Stay away from their wired stuff. We've had problems with the EdgeRouter and the ToughSwitches. [1] https://news.ycom

You mention scraping, but did you actually scrape these? I just discovered that IMDB publishes textual data dumps. They appear to be pretty complete. Terms of use are non-commercial, but I'd love to see more analyses like this! http:&

Interesting, and makes sense. Why would you need the full BFT Paxos among trusted participants? Still, the claim that Bitcoin represents "a breakthrough in computer science" on the Byzantine Generals Problem rings false to me. Fir

How do you know they're building off of non-public blocks if they're doing so in secret collusion? For what it's worth, Felten et al have a somewhat convincing (if not yet rigorous) argument that members of a so-called selfis

Bitcoin is the first practical solution to a longstanding problem in computer science called the Byzantine Generals Problem. Wait, isn't Paxos arguably the first practical solution to BGP? [0] [1] It's been in production use at

Careful using this, I'd personally wait until a proper security audit was done. For instance, you're getting the user's wallet passphrase at line 1361. Does the passphrase just sit around in memory somewhere, long after the w

The problem with this is that (1) + (2) means the server now knows the user's address book. They're trying to avoid that with encrypted bloom filters and blind signature queries.
