10/4    motd routing nerds, help me out.
        let's say i am torrenting stuff on my laptop.  I want
        of course my SSH connections to be responsive and fast,
        but the upstream torrenting gets in the way.  Could i
        implement QOS somehow on my local machine and improve
        SSH?  I'm running Linux.  Would I have to make a virtual
        machine somewhere on my laptop and run QOS in that?  Thanks!
        \_ or just use your torrent client's builtin bw limit options
           \_ no no you don't understand, have you ever used QOS
              on a router before?  You can make your SSH packets
              have a higher priority than your web or torrent packets,
              reducing the latency for your ssh sessions.  If you limit
              the upstream of your torrents... your downstream becomes
              slower
              \_ sympathy factor crashes like rock. back in my day we got 300
                 baud and we were glad for it!
              \_ if you're bottlenecked on the inbound, no amount of
                 fiddling with your router's QoS settings is going to help.
                 Maybe if you could fiddle with your ISP's router, but I
                 suspect they won't be sympathetic to your torrent leeching
                 needs.
                 If you're bottlenecked on the outbound, limit your torrent
                 clients' upload speeds (or play with QoS).  It doesn't take
                 backing off much to give huge improvements to ssh and/or
                 other interactive programs.
                 clients upload speeds (or play with QoS).
           \_ get a faster pipe, whiner
        \_ So-called "gaming routers" can put preferences on ports.  That's
           quick solution.
           \_ Not only is this a quick solution, but an excellent solution.
              I bought a DLINK gaming router and never looked back. I get
              the best of all worlds-- filling up the pipe AND get small
              latency for ssh and X11 related things.
           \_ agree that this is one way to do it.  increase priority for
              port 22 outgoing (router should also be smart enough to
              prioritize incoming packets for the session), and back off your
              upstream torrent cap a bit until you're satisfied.

8/16    I just left my employer. They didn't ask to get their HW back.
        Is is common for employers to contact me a few months/years later
        and ask for their HW back?

        paycheck (and maybe even try to get back the laptop they gave me)?

12/21   In Emacs, how do I make it so that it will resize its screen
        when the maximum resolution of my monitor changes? When I
        use my laptop, my emacs is too big (and I can't resize it
        because the bottom-right corner is not accessible).
        \_ Which OS?  Can't you drag the top border (not a corner) to resize
           the height to be smaller?

           is strategically valuable to not driving people away from macs.

3/12    I am curious what others think of tablets like iPad. They don't seem
        useful to me, but I use my computer for more than web browsing,
        Facebook, and Twitter. Why would I buy one instead of a laptop?
        They seem like a disabled laptop to me, but at a higher price.

           development, QA and other office use (HR, Finance, Receptions, etc.)
           from WinXP to Win7 a few months ago.  Our products now primarily
           support Win7/Win2008 and secondarily support WinXP/Win2003.

        I always had matte in the past. I use my laptop just about everywhere
        and glare is a concern. Should I stick with matte? I noticed
        glossy is the default now.

        impending Apple laptop refresh?
