Avoid my house tomorrow night, children, for I will not be handing out chocolate. Enjoy your organic fruit snacks!

Moo hoo ha ha!

Home-made banana bread! I underestimated how much the raw dough would expand but it's still super yummy.

LMAX developed a 6 million TPS retail processor that runs on a single node. How?
* Using the correct data structures for the task at hand (don't use an ArrayList if you should be using a LinkedList)
* Developing data structures that take advantage of the JVM (i.e., a HashMap backed by primitive long type keys)
* Keeping the working state in memory (recovery via replay)
* Abandoning existing transactional software paradigms (actors, relational databases and transactions, queues, etc.)
* Concurrent unmarshallers and marshallers using a circular list of ring to provide natural ordering and locking (Disruptors, or a multicast graph of queues for parallel consumption)
* Designing business processes to output intermediate results when external resources are required (additional lookups, verifications, etc.)
* Performance testing and tuning with the real machine's performance in mind, not assumed performance

Why we think there's a multiverse

http://scienceblogs.com/startswithabang/2011/10/why_we_think_theres_a_multiver.php

I found the short description of the conversion of high vacuum energy into particles and radiation to be enlightening. I'd be interested in seeing this expanded to cover current theories with cosmic strings and universes with different cosmological constants and laws of physics. Also, given that the universe was superimposed onto other possible quantum states, does that imply that there are essentially an infinite number of similar universes within a multiverse for each universe's inflationary periods?

Everything I Ever Learned About JVM Performance Tuning @ Twitter

This is worth keeping in the back of the toolbox. It's not very applicable to the work I'm doing today, but for anyone working with persistent, heavily trafficked JVM services this could be very valuable. I wish I'd know about slab allocation when I was working on Amazon Plogs.

Everything I Ever Learned About JVM Performance Tuning @Twitter

Summarizes about a year worth of experiences and case studies in performance tuning the JVM for various services at Twitter.

I heard a funny story from Jonathan Johnson and Patrick Byrne at today's company stand-up. Patrick was in San Francisco being deposed by attorneys for Goldman Sachs and was asked about his public statements and writings about corruption in the U.S. financial system. The lawyers finally got to Patrick's letter to the editors in response to the Wall Street Journal editorial "Do Nudists Run Wall Street?" in which Patrick wrote, "I also think that if this nation ever grasps how its savings have been looted through this mechanism, a few million Americans are going to show up at the corner of Wall and Broad with pitchforks and nooses." ( http://online.wsj.com/article/SB114558723216732121.html )

As if on cue, while waiting for Patrick's response, a bullhorn sounded from 24 floors below the posh law office: the San Francisco wing of the Occupy Wall Street movement was on the march. Jonathan told the lawyers, "Your jury pool has arrived."

I finally finished the trend chart for work. It took one month, a bunch of features and fixes on sticky notes, one RESTful servlet, and a dozen bug fixes or tweaks to jqChart plus my own custom JavaScript libraries. Internet Explorer 7 and 8 compatibilty work took nearly half the development and testing time. It goes live Monday.
