         <title>One down and three point six to go.</title>
         <description><![CDATA[<p>Ben Folds with the Chamber Orchestra of Philadelphia last night, at the Mann Center.</p>

<p>Amazing.</p>

<p>Just amazing.</p>

<p>"Steven's Last Night in Town" pretty much <em>requires</em> an orchestra, really.</p>

<p>He played a couple new tracks last night, too, for the album dropping on the 30th. Definitely looking forward to it.</p>

<p>Even in the middle of a little hurricane, the place was packed. Everyone decked out in rain gear and ready to have an excellent time. And they did.</p>

<p>We ran into Nick and Mariah while looking for seats, which was hilarious though -- really -- not all that unexpected. (We hit up Doobies after with them, and ran into Gallo (Hi, Eric!), who is back in town and sounding very productive. Very excited for him.)</p>

<p>And, as H commented after the "three part harmony" section of the night, the Mann center has <em>great</em> acoustics.</p>

<p>Seriously. Last night was awesome. There's a reason H has seen Ben Folds twelve times now. I certainly hope I get to; I can't imagine it ever getting old.</p>]]></description>

         <title>pkgsrc in sparse zones.</title>
         <description><![CDATA[<p>Recently I moved our x86-64 pkgsrc build zone to another system. When I did so, I had forgotten I had built the original zone as full, to get around an annoying <code>install(1M)</code> bug. Basically, when you tried to build a package, it would attempt to recursively <code>mkdir /usr/pkg</code>. On sparse zones, <code>/usr</code> is shared read-only from the global zone.</p>

<p>So the install would fail, because it couldn't create <code>/usr</code> for obvious reasons. At the time, I thought I had tried various <code>install</code> programs, but given that the problem was being re-addressed and I didn't feel like reprovisioning a zone, I figured I would tackle it again.</p>

<p>After some minor discussion on <code>#pkgsrc</code> and grepping through <code>mk/</code> I "discovered" the following variable:</p>

<div class="quote">
TOOLS_PLATFORM.install?=        /usr/pkg/bin/ginstall
</div>

<p>Added to <code>mk.conf</code> and all is good. Mainly because <code>ginstall</code> actually uses <code>mkdir -p</code>, so...</p>

<p>The contents of <code>pkgsrc/mk/platform/</code> are very useful if you aren't on NetBSD.</p>]]></description>

         <title>In rainbows around the bend.</title>
         <description><![CDATA[<p>Went to the Radiohead show in Camden last night, with H, her sister's friend, and a friend of H's from NYC (who I'd heard a fair amount about, so it was nice putting reality to stories).</p>

<p>We got some dinner at Penang beforehand (a spinach dish I hadn't had before was ordered, and it was just as delicious as everything else there), then took the ferry over the river. We had skipped the opening act (Grizzly Bear), and got to the stadium just as the show was starting. Awesome timing.</p>

<p>The set list seemed like a good mix of new stuff (most of which I wasn't familiar with) and older stuff (which I was).</p>

<p>They played <em>Climbing Up the Walls</em>, <em>Everything In Its Right Place</em> and <em>How To Disappear Completely</em>, which was enough to make me a happy little monkey.</p>

<p>The effects were quite awesome, comparable to Massive Attacks.</p>

<p>After the show, we sat on a bench eating pretzels and vending-machine-ice-cream waiting for the ferry line to become less insane (a thousand or more people were waiting), and would have been the last group on the boat except some old guy wandered up behind us basically as we were boarding.</p>

<p>An excellent evening, for sure.</p>]]></description>

         <title>Another broken morning.</title>
         <description><![CDATA[<p>So this morning has been... annoying.</p>

<p>A box was rebooted and didn't come back up. Network came up (pingable) but not ssh. Based on previous idiocy with this system, I suspected it had something to do with filesystems not being able to mount at boot. I shot off a mail to the NOC monkeys, not expecting much (and four hours later, still no response from them), and then started trying to get into the system myself to fix it.</p>

<p>The box in question is a <a href="http://www.sun.com/servers/x64/x4150/index.xml">Sun X4150</a>; a really nice system (though now that I've had a <a href="http://www.sun.com/servers/coolthreads/t5120/">T5120</a> for a while, I have to say I really do much prefer SPARCs simply for ease of administration), with a really lame-ass LOM (ELOM). But: Whatever. So I go to start the console via the LOM... no joy. Apparently console is not redirecting. So, ok, I should be able to get at glass (thanks for the reminder, dlg) via the web interface.</p>

<p>Of course there's no VPN at that site. So I kick open netcat and don't have much in the way of luck. After a few minutes of screwing around with it, I give up and download <a href="http://haproxy.1wt.eu/">haproxy</a>. In about three minutes I have it compiled, configured, and forwarding :80 and :443 for me.</p>

<div class="quote">

<p>listen proxy1 0.0.0.0:80<br />
  mode  http<br />
  balance roundrobin<br />
  server test 192.168.11.10:80<br />
  contimeout  3000<br />
  clitimeout  150000<br />
  srvtimeout  150000<br />
  maxconn 60000<br />
  redispatch<br />
  retries 3<br />
  grace 3000<br />
  option  forwardfor<br />
  option httplog<br />
  option dontlognull</p>

<p>listen  ssl-relay 0.0.0.0:443<br />
  option  ssl-hello-chk<br />
  balance source<br />
  server  inst1 192.168.11.10:443</p>

</div>

<p>I log into the LOM, start the redirection Java app, and... nothing.</p>

<p>And... <a href="http://blogs.sun.com/pmonday/entry/paul_hearts_elom">Mac OS X Java bullshit.</a></p>

<p>So I start an old Parallels OpenSolaris image I had laying around, connect to the LOM that way and... get an I/O connection error. Figuring that the KVM was running on another port, I sniffed off my firewall and discovered that yes, it wanted :8890 as well.</p>

<div class="quote">

<p>listen  ssl-relay 0.0.0.0:8890<br />
  option  ssl-hello-chk<br />
  balance source<br />
  server  inst1 192.168.11.10:8890</p>

</div>

<p>Did that, got into the box and discovered the problem was...</p>

<div class="quote">

<p>[20080813-05:43:12]:[root@brood]:[~]# tail -2 /etc/vfstab <br />
/dev/zvol/dsk/data/zones/lb-arc/root /dev/zvol/rdsk/data/zones/lb-arc/root /zones/lb-arc ufs 1 yes logging<br />
/dev/zvol/dsk/data/zones/lb-arc/root /dev/zvol/rdsk/data/zones/lb-arc/root /zones/lb-arc ufs 1 yes logging</p>

</div>

<p>ugh.</p>

<p>A svcadm clear filesystem/local later, and all was well.</p>

<p>sigh.</p>]]></description>

         <title>ZFS and 32bit platforms.</title>
         <description><![CDATA[<p>So for a while now I've been struggling with an older Xeon system which becomes more and more unresponsive until it finally hangs, when under a moderate amount of I/O load.</p>

<p>I asked <a href="http://mail.opensolaris.org/pipermail/zfs-discuss/2008-August/049971.html">zfs-discuss@</a> about it, and received a <a href="http://mail.opensolaris.org/pipermail/zfs-discuss/2008-August/049994.html">very helpful response</a> from Marc Bevand.</p>

<p>Now the kernel heap bounces between 1.2GB (idle) and 1.4GB (loaded). The ARC has maxed around 400MB, but I haven't been doing any major reads off the box yet, just a lot of write I/O, so I don't think that's particularly surprising.</p>

<p>Yay.</p>

<p>(This experience really reminds me that I need to re-read <em>Solaris Internals</em>. I could have solved this problem myself, if I refreshed on those books periodically.)</p>]]></description>

         <title>Vihuela pickin&apos;.</title>
         <description><![CDATA[<p>Went to <a href="http://grg-mgmt.com/distritorestaurant.com/">Distrito</a> for dinner tonight. H notes that it's run by <a href="http://www.tintorestaurant.com/">Amada</a> and <a href="http://www.amadarestaurant.com/">Tinto</a> head chef Jose Garces.</p>

<p>The decor is pretty cool, very oddball, and somehow manages to be eccentric without becoming tacky. The restaurant is huge, two floors, plenty of floorspace. Huge booths that put you in mind of <em>2001</em> line the walls.</p>

<p>The ratio of servers to customers was impressive, though presumably if the place is ever packed, that would be less noticeable. It was perhaps a quarter full tonight; H made reservations, but they were certainly not needed.</p>

<p>The food, "upscale Mexican", was pretty excellent. I especially enjoyed the carnitas tacos. H was having fits over the mole verde, and it <em>was</em> pretty tasty, but I'm just not a big mole guy. The queso fundido was <em>delicious</em>. We ended up sharing five items, and were both pretty stuffed by the end of the meal.</p>

<p>They also serve roasted nuts (heavy on the lime -- very tasty) to snack on between dishes.</p>

<p>Next time we go, I'm definitely going to save room for a churro. Because churros are delicious.</p>

<p>It's not a quiet place, which is probably my biggest complaint. There was a mariachi wandering around; he was very good, and it alternated between being awesome and annoying as it made conversation basically impossible (to be fair, I had a sore throat, so I couldn't speak particularly loudly anyway).</p>

<p>Overall, it's a very cool place, and worth the trip if you even remotely enjoy Mexican food and quirky restaurants.</p>

<p>Between the enchiladas (which had a subtle traditional taste under the upscale) and the mariachi, the place honestly made me kind of <a href="http://www.ci.yuma.az.us/5549.htm">homesick</a>.</p>]]></description>
