   I think it's mainly a fiber library, actually. The TCP and channel functions yield and resume automatically based on when the underlying operation blocks. They have yield(), but I don't see the opposite, the ability to explicitly

   Fibers and coroutines are different uses for the same thing. If you schedule your coroutines based on the kernel scheduler, they're fibers. If you jump between fibers explicitly, they're coroutines.

   Fantastic article. We need more deconstruction of "fads" (which I don't mean in a pejorative sense) so that we can quickly understand them without sacrificing tens of thousands of man-hours slowly coming to terms with each on

   You'd configure the application to write to the FUSE mount, then run it through an average workload. The FUSE module records the e.g. writes and fsyncs and can simulate a crash at any point during the run. Perhaps there'd be some

   I wish there were a FUSE-based file system for testing the consistency and durability of arbitrary applications. Surprisingly there doesn't seem to be such a thing.[1] There's also a list of other things that could be built with F

   No mention of security? Xen isn't perfect, but according to the Qubes team it's the best we've got. > We still believe Xen is currently the most secure hypervisor available, mostly because of its unique architecture featur

    I'm not part of the Java world at all, but I'm starting to think that Azul Systems is one of the few groups of people who know what they're doing with regard to Linux performance and the user/kernel boundary. I recently

    Thanks for acknowledging the problem with the graph. We'll have to disagree over "correct in spirit" versus "stupid." I suggested building a LSM out of cache-oblivious b-trees because of the claim that they were bet

    Thanks for taking the time to reply. In Leif's post, the graph shows "b-trees" on the inner curve. The equivalent point on the outer curve would be a data structure that makes the same read/write tradeoffs as a b-tree, b

    Fractal trees are not "LSM-trees, but better." Fractal trees are more read-optimized, whereas LSM-trees are more write-optimized. A fully compacted LSM-tree should be equivalent to a b-tree in terms of read performance. However I

    SQLite supports a single writer at a time, so writing large amounts of data limits your write throughput. A file system can cache data for several files concurrently and fsync them independently when you're done. I believe SQLite also

    Hash collisions are dependent on the length of the hash and the quality of the algorithm. AFAIK there has never been a _single_ SHA-1 has collision, and it's an old algorithm that people don't recommend using anymore. As mentioned

    Those changes were made for security, to make social engineering attacks more difficult. You can still type JS into the address bar, you just can't copy and paste it.

    So in summary, I believe that the comments in the MySQL news posting are slightly confused. On MacOS X fsync() behaves the same as it does on all Unices. That's not good enough if you really care about data integrity and so we
