   Question for jgrahamc: how much more efficient is your binary delta algorithm than cperciva's bsdiff [1]? I assume since you've got the preimages of compression, as well as control over the compression format, that the diff and patch operat

   They use MAP_ANONYMOUS, not a file-backed mmap. https://github.com/twitter/fatcache/blob/master/src/fc_util....

   It would be trivial to batch writes to the mmap'ed region. Reads would still benefit from OS caching.

   Curious, why not just use an mmapped file for the store a la varnish? If the file lived on the SSD you'd get in-memory caching for free from the OS.

   BSD userlands have jot(1) instead of seq(1). Annoying that the arguments differ, but no need for a new script. http://developer.apple.com/library/mac/#documentation/Darwin...

   Yup. OpenWRT supports 802.1q VLANs. So does the stock firmware from Ubiquiti, AirOS (which is just linux). http://wiki.openwrt.org/doc/networking/network.interfaces#vl...

    This isn't a new idea, although we have yet to see someone execute it well. Plura Processing tried it back in 2008. Here's their Show HN: http://news.ycombinator.com/item?id=347359 Plura ran into trouble because they built a pay-for-grid

    I'll second that. For example, here's a bot that logs every channel you invite it to...in 50 lines of shell. How big would the equivalent XMPP bot be (libraries included)? https://github.com/acg/logbot/blob/master/bin/logbot.sh

    True. Empirically though, very few self-taught programmers seem to know about FSMs or other core CS topics like complexity theory. This has been my experience interviewing programmers at least.

    Alternatively, if you don't trust a large program with dropping root, you can factor out the binding and listening into a separate program. Then accepting and everything beyond can be done with normal privileges. Assuming a tcpserver-like p

    Instead of "#ifndef _SOME_HOPEFULLY_UNIQUE_NAME_H" I've started using "#pragma once" -- it's likely supported by every compiler you care about. http://en.wikipedia.org/wiki/Pragma_once

    Why reinvent version control inside of WordPress? I'd rather version my content in git and build a static site from that. I think there's a real opportunity for github, or a github app, to revolutionize publishing by building on the existin

    Tried notmuch a while back, ended up going back to mutt. If you're an emacs user the notmuch mode may work well for you. The notmuch.vim plugin, OTOH, leaves a lot to be desired. More promising is this fork of mutt that adds notmuch support

    Useful idea. I sometimes use time [1] to print stats at the end of the program's run, like so. /usr/bin/time -f 'user=%U system=%S maxrss=%M ins=%I outs=%O" PROGRAM Seeing stats while the program is running is nice though! Also, cu
