4/21    I guess short-GOOG-at-100-guy hasn't gotten his account turned
        back on yet.  -tom
        \_ I think he retired after he vested, exercised, and sold most of
           his GOOG options and unit stocks at around 300-350. It coincided
           with the time frame when wall logs disappeared.
        \_ By the way I wonder what the quant says about GOOG:

4/02    We use Perforce at work for revision control. It seems to work okay.
        Lately, a lot of the newer developers are saying that Perforce
        sucks and we should switch to Mercurial or Git. I have done some
        searching on the Internet and some others have this opinion. Added
        advantage is that Mercurial and Git are free. However, there would
        be some work to switch for the sysadmins and the developers.

4/26    I see that soda has an ipv6 address but ipv6 traffic from this box
        doesn't actually work (ping6 <DEAD>ipv6.google.com<DEAD>, ping6 http://www.v6.facebook.com
        Is this expected to work?
        \_ Soda doesn't have a real IPv6 address.  The IPv6 addresses you see
           in ifconfig are just link-local addresses; any IPv6-capable machine
           will autogenerate these, whether or not it's connected to an IPv6

        not working
    \_ That would be because we've yet to set them up afaik. Steven *does* have
    a job after all. The idea is that we want a separate computer mounting the
    web directories, so that if an exploit compromises the webserver, the shell
    server (soda) itself will be insulated from the attack.

3/8     I'm reading about an old exploit where someone used a buffer overflow
        in a printer daemon to get "daemon privileges," which allowed them
        to use another exploit on the mail delivery program to get root.  I'm
        not sure what daemon privileges are.  Is there some set of priveleges
        that most daemons run on that is higher than user but lower than root?
        What are they?  I've never heard this before.

12/9    Another idea for the CSUA that lets you spend money and maybe get some
    cool toys. Instead of buying a beefy server (like say, a massive server
    with 20 386DX processors), buy a few cheap machines (like the ones
    mentioned below) that have good disks and work on failover / load
    balancing. A netscaler or other piece of hardware is complete overkill,
    but maybe hacking an OpenBSD box could do the trick. The idea is that

Stephen Gandel, MONEY Magazine staff writer April 20, 2006: 11:16 AM EDT NEW YORK (MONEY Magazine) - It's no surprise that George Sauter, the chief investment officer of index fund king Vanguard, argues that most investors are wasting their time and their money when they try to beat the market. So why is Sauter launching funds that will attempt to do precisely that? Because he believes that while man can't outperform, a machine can. "Computers," Sauter says, "can systematically take advantage of all the mistakes we humans make." Research) now runs nine quantitative, or "quant," funds in which computers make buy and sell decisions based on their constant crunching of hundreds of thousands of numbers. Of the five Schwab funds that have three-year records, four have whipped at least 75 percent of their peers. "This strategy has a lot of teeth," says Jeff Mortimer, Schwab's equity investment chief. Vanguard's first computer-run fund, Strategic Equity, has risen 27 percent on average for the past three years, putting it near the top of the hot midcap category. In April the firm launched a small-cap fund, and Sauter thinks there's room for more. Research) and American Century have jumped on board as well. The popularity of quants stands in sharp contrast to that of the late '90s, when investors lost interest in the funds because they couldn't keep pace in the Internet bubble. In the seesaw market that has followed, however, quant funds have done well. In the past five years, they have returned an average of 61 percent a year, according to fund research firm Lipper, vs. To be sure, that's too short a period to declare the contest between man and machine over. But supporters like Sauter say that computer-managed funds can beat the market with less risk than human-run funds. Research) Asset Management concluded that while over 15 years a human manager can beat a quant fund in absolute terms, once you adjust for the extra risk the human manager had to take to get that result, the quant fund comes out ahead. "Quant funds are a well-established strategy for institutional investors," says Coral Gables, Fla. "They are becoming a story for individual investors, and for most people they probably make good sense." Just the numbers, Ma'am Both man and machine evaluate investment prospects by comparing financial statements and share prices, looking for stocks that are cheap relative to assets, earnings or some other quantifiable measure. Most human fund managers then visit the management of those companies, try out their products or do whatever it takes so they can make an educated guess about how a business will do in the future. Computers, on the other hand, buy and sell strictly by the criteria they have been programmed to watch. Vanguard compares stocks with others in their industry and buys those with the best growth prospects and lowest valuations. Schwab's computers, which rank 18,000 stocks, focus on those that are increasing earnings faster than expected and are rising in price. Janus, on the other hand, cares more about stock movement. Its computers buy shares of companies that go up and down regularly, and try to make money from that volatility. So how do quant funds compete without doing hands-on research? For starters, computers can follow far more stocks than can a manager who is out visiting executives. The average quant fund tracks thousands of stocks and owns hundreds. But the real advantage machines have over people is that they're not human. Emotions trip up professional money managers like they do the rest of us. Pros hold on to plummeting stocks, not wanting to admit a mistake. "Computers don't have bad days or biases," says Richard Thaler, a University of Chicago economics professor and principal of Fuller & Thaler, a money management firm that tries to exploit human error in the market. "A computer won't like a company just because it went to the same college as the CEO." Finally, unlike human managers, computers don't earn six-figure salaries or require legions of analysts to support them. Vanguard's Sauter says he can run his funds with a third of the people needed by the typical mutual fund. So computer-managed funds should be able to charge lower fees than other funds. According to Lipper, computer-managed funds charge investors 13 percent of the portfolio in fees a year on average, only a hair less than actively managed funds. And all those data give quant funds itchy trading fingers, driving costs up and returns down. But the second hurdle they have in trying to outperform is a tougher one: Quant funds have trouble anticipating change. MONEY 65, recalls that in the 1970s quant funds failed to understand that the ramp-up in inflation would drive the market. Similarly, even before the Internet bubble, quant funds lagged because they didn't foresee that technology was the next big thing. The best human investors have a much better chance of significantly outperforming the market than computers do. On the other hand, human managers are also much more likely to lose you a lot of money. The ones below have modest expense ratios, and they could help you squeeze a tiny bit more return out of your portfolio without taking on big risk. That's not a Buffett-size gain, but they're not making any more of him. Computers, on the other hand, get better with each new model.
