His graphs seem to be way over fit. Look at
this.
It would make way more sense just to do a simple linear regression of evening commute duration against departure time.
Unfortunately this article doesn't seem to be as applicable as one might hope: for those of us not living in Huston or traveling different routes it's hard to get more out of it than "don't drive during rush-hour," which most people could
figure out on their own anyway.
Knoppix 4.0 is a fantastic distro for people who don't want to spend time configuring stuff. I'd hand off a knoppix cd or dvd to a non-tech business person over suggesting a regular distribution any day. With a decent sized USB thumbdrive, anybody can be functional in under a minute.
I got a "come-see-us" reply from Graham's Y-Combinator program. Before the interview I got an offer at a reputable search engine company in Mountain View, CA. The Y-Combinator people didn't like my idea, and the amount that they were going to fund for a three person team was less than what I'd make in California, so I ended up putting my startup on hold. My internship has been fantastic, but I somewhat regret not getting further on my project. I'll be working on it full time next summer.
I'd advise anybody in a similar situation to ignore VC's (including Y combinator) and start working on version 1 as soon as possible.
When parrot/perl6/pirate/etc. gets off the ground, the open source community will have a vm of their own, and it will be much easier to move between languages within an application. I suspect this will mean that much more language specialization will take place. You'll see all sorts of small languages pop up for tasks like gui programming, stored procedures, templating, and for domains we haven't even thought of as needing their own language.
R (awesome statistical package also does matrix stuff well).
Perl Data Language, commonly used by astronomers, much like the rest of perl in that it's difficult to wrap ones head around but capable of extremely powerful (i.e. terse) code.
There's a book titled "In the Blink of an Eye," which details the Cambrian ecological explosion, which was precipitated, by (you guessed it), the emergence of vision among vertebrates. I expect a similar explosion for machines. In the modern era, we have rather well advanced robots, in terms of data sensing and actuators, but really crappy AI and control. The availability of decent remote control requires wireless video (who want's a robot attached to the wall?). UWB (or perhaps one of its successors) will make robotitcs fessible. With the coming shrinking of the labor pool due to the baby boomers retirement, there will be a demand for labor-saving technology, a void which robotics will be poised to fill.
...it's the students. Any moron with half a brain can lecture from a textbook on algorithms. If anything I'd say that the classes at the big name schools are worse because the faculty are judged based on their research rather than their teaching. I attribute a large part of my understanding of cs to interactions with other students.
Disclaimer: I got my undergrad from UC Berkeley, where this effect is magnified due to a high student-to-teacher ratio.
"It takes a lot more than a simple little gene to make something pathogenic. But you could teach these skills to a high-school student, and you could probably teach them to an artist."
I very much agree. I think the reason that Java has risen to its status today is because it constrains the programmer to be explicit with what methods are being called upon what data, and thus easier for someone other than the orginal writter to understand what's going on. In Java A=B will do the same thing every time (as far as the programmer is concerned), but in C++, A=B may mean any number of things depending on operator overloading. I think XML has the same advantage over S-expressions that a strongly typed programming language (E.G. Java) has over an untyped language: transparency. Image if HTML was based on S-expressions:
Sure if you have an editor that will show you matching (), then the above s-expression makes sense, but otherwise it would be a nightmare trying to figure out why Here was not in bold. HTML and XML are much easier for humans to read (and thus debug) because it's clear where in the tree you are editing, just as it's easier to program in Jave because you are forced to be explicit about what data types you are manipulating and what calls you are making.
From the article: A judge ruled last summer the pension changes IBM made in the 1990s violated federal age discrimination laws. Palmisano said Tuesday IBM hopes to win the case on appeal and avoid an estimated $6 billion in liability.
IBM has discrimiated against older workers in the past, and they're buying a company that discrimiates against aged works now, but other than sharing the common feature of discrimination by big blue, these two events are unrelated.
Each team may use only one computer or one terminal (one keyboard and one monitor). You can't have a distributed team working through the internet.
It is forbidden to use systems for symbolic computation (e.g. Mathematica, Maple, Matlab) and special libraries (e.g. LEDA).
Most of the programming languages listed (Pascal, C, C++, Java, Basic, Smalltalk, Lisp, Logo, Perl, Python) have symbolic libraries, but it looks like you can't use those and'll have to reinvent those wheels. Hmmmm.
It's been 23 years since 1981. Thus there have been about 15 18-month doubling periods. Based on the advert and Moore's law, one would expect 16k * 2^15 bytes (aka 2^29=512MB) to be available on computers these days.
From the article: "It's very much a Coke/Pepsi situation. If you are an ad agency dealing with Pepsi you don't pick up business with Coke."
This seems like a legitimate reason to refuse a Linux job. In the current climate it's clear to most that Linux is strong competition to Microsoft. I'm suspect that there exists at least one other company offering similar services, which isn't doing business with Microsoft directly, and can see the value in becoming a provider for the Linux community.

So Perl 7 will be the last major revision. In fact, Perl 7 will be so perfect, it will need no revision at all. Perl 6 is merely the prototype for Perl 7.:-)
In the post-SSC cancellation era, do you think the American government is willing to fund multi-billion dollar high energy projects? Are physicists of late at all hampered by a low equipment to brain ratio?
There has been extensive hype about super symmetry, strings and what haveyou, but most of this theory is as of yet untestable. Do you think that this sort of theory is BS or is it genuinely helping the exploration of the high energy realm?
I'm very under impressed with this article. *Most* of the laws of physics are symmetric with time, the exceptions being strange things like kayons. That a particle is moving twards more order (which the author implies) doesn't mean that it didn't have a past or doesn't have to play by the rules of the rest of mater in the universe. People who think about dark matter are worried about what type of stuff it is (weakly interacting massive particle [wimps], nutrinos, gas clouds, etc). What that stuff may be doing in our future (its past?) doesn't solve the basic question of what it is.
We already know what matter moving backwards in time looks like, and we've created it in labs. It's called antimatter.
Sometime in the not so near future (say, ten years from now when distributed.net cracks rsa64) we might have a desire to simulate large portions of the human brain. With network response times on the order of msecs it seems possible to locally simulate a tiny bit of a brain and compile the results to meet or exceed the processing power of a human's 10^11 neurons.

You point out that the common vote doesn't actually elect the president. If the election isn't being determined by actual votes, gross imprecision might not be to much of a problem. There needs to be some sort of test before the public would accept this as a valid form of voting. For example, perhaps an internet poll could be used to *suggest* how domain names are assigned. (Washington could use some common internet-user advice on such issues anyway).
