Does anyone else have a major problem with the idea of using a closed-source SSH client? Even if it is App Store reviewed, I just can't bring myself to type production passwords into such a thing. For this reason, and because I'd also like

Cool. Is the consensus algorithm straight-up Paxos, or are there modifications? The Paxos Made Live [1] paper from Google raised some interesting issues. [1] http://labs.google.com/papers/paxos_made_live.html

I was curious how they implemented prefix matching, so I went and looked at the code [1]. Unfortunately, this is just a simple linear scan that calls .startswith(). It is possible to do fast (log N) prefix matching with radix / critbit tree

Are you really comparing these github projects to the initial release of the Linux kernel? Have you read the source to either? Or stopped to consider their scope or potential impact? Not to disparage the Greplin team's work -- I think it's

But you could prevent reuploads with per-user de-duplication, while avoiding the privacy issue of cross-user de-duplication. I could see why this would be more work to implement (you have to key on user+contenthash), but it would still be i

If you don't mind my asking, what is the percentage savings achieved by de-duplication across all of Dropbox? Some others here have wondered if it was premature optimization.

Maybe you're solving a different problem, but I'm not sure emitting one key-value pair per line is ultimately the way to go: $ echo '[{"a": [{"b": {"c": ["foo"]}}]}]' | jsonpipe / [] /0 {} /0/a [] /0/a/0 {} /0/a

Interesting. For faster flattening of nested structures into paths -- and the inverse operation, unflattening -- you could use this Python C extension: https://github.com/acg/python-flattery Full disclosure, I'm the author. ;) It uses "."

Maybe I will. ;) A few years back, I wrote a multiplexer / tunneler similar to Sshuttle in Python for a "Go To My PC" style web service. We wanted to tunnel over ssh, but had problems automating the client key generation and first-time conn

Very cool. I wonder how hard it would be to port the muxer core to C, and run it under tcpclient / tcpserver on either end of the ssh connection.
