Is an SPSS monster like a SAS bunny rabbit?

A friend of mine had a Google Talk status of "Now I'm the SPSS monster" today. Lately, I have picked up the contagious habit of making fun of people who use gooey (GUI) SPSS, and so I responded by e-mail, "Is an SPSS monster like a SAS bunny rabbit?" She responded, "Could be. Or an R-invader." I couldn't resist letting this snowball turn into the avalanche it really could be, and so...

Kick S. Way to JMP on that one and even Z-score. Such a rejoinder makes me want to click away to one of the Minitabs of my browser. Phew, all of this stat talk makes me want to regress back into MATLAB; even if I am still centrally limited there, at least I can feel normal again.

Anyway, I wasn't trying to be mean. If I was, I hope you won't log this transformation and hold it against me later. I'm certain I can transcend and function better in the future; a higher power law need not intervene. Hopefully this hypothesis is correct and you will see some significant change. That should help you restore your confidence.

On a different note, I saw some Monte Carlo tulips at the zoo last weekend; it seems risky to have planted those at this time of the season, but hopefully they will Excel. If they do die, I'm afraid this story will have a heavy tail indeed.

By the way, yesterday for graduate appreciation day, Jessie got a coupon for $1 coffee at the expensive campus Starbucks. With the discount, prices are about normal. I guess there is no such thing as a scale free lunch. Shoot, I'm afraid my coffee has gone cold and is starting to taste a little bit like Poisson.

Well, enough of this. I'm sure if you remove the outlier that is e-mail thread, you'll find that the remaining e-mails are far less skewed and better fit the distribution you have come to expect.

I hope all of your days are better than average! --

There are parts of that that I'm not that excited about, but overall I'm pretty proud of myself.

Geek Squad sucks

There are two possible reasons for this response:

• "Agent 191" doesn't understand "Reply-To" and delegating of support messages.
• "Agent 191" might think that my message was some internal joke played on her by other people at Geek Squad.

Either way, "Agent 191" looks a bit like an idiot or an ass (or both). When you see those Geek Squad commercials, these are the people you're dealing with.

I sent a snarky response back (one to info, and one to Agent 191 directly), but I haven't received anything else. So, now when I teach classes to my young engineers, I refer to "Geek Squad" where I used to say "lay people." Snap! (or something)

An e-mail I just sent to Geek squad:

Subject: Complaint: Packaging information of CAT-6 crossover cable

"Geek" squad --

     I purchased a CAT-6 crossover cable of yours yesterday. The packaging surprised me. You advertise yourselves as some sort of elite group of geeks, but the printing on the packaging makes me wonder if any of you know anything about technology at all.

     There are several examples on the front of the package, but one sentence in particular is especially troubling:

"Your geek squad network crossover cable uses an RJ45 connection allowing you to connect between similar types of equipment without the use of a hub; one PC to another PC for example."

     The difference between a crossover cable and a standard patch cable has nothing to do with the "RJ45 connection." For one, both cables use a type-45 "registered jack (RJ)". "RJ45" describes the PHYSICAL connector. That is, it describes the PLASTIC end that mechanically snaps into place when the male version is inserted into the female version.

     The difference between a crossover cable and a standard patch cable is the 8P8C (i.e., "8 position 8 contact") termination type. A patch cable has a T568A termination at one end and a T568B termination at the other end.

     It would be wise for you to change the wording to something like:

"Your geek squad network crossover cable uses an T568A-to-T568B termination allowing you to connect between similar types of equipment without the use of a hub; one PC to another PC for example."

Otherwise, it just simply doesn't look like you know what you're doing.

     When I picked up the cable and saw the text above, I was seriously worried that it would have the 500 MHz bandwidth I needed. Unfortunately, because it was the only one available and I didn't want to terminate my own and risk the crosstalk, I had to buy your expensive cable. My computers came up with gigabit link, so I'm guessing things are fine, but I wonder what I'd find if I walked down the hall and tested these things on a network analyzer.

     Clean up your act, Geek squad.

     Thanks for your understanding --

A bit much? (yes, I realize there's a typo... I said "patch" once where I clearly meant "crossover")

Roomba Robots as Development Platforms

Evidently, the iRobot home robots (the Roomba and Scooba varieties, with emphasis on the former) are now being used as robotic development environments.

It makes sense. They're tiny. They're robust. They're packed with sensors and motors. On top of all of this, they've gone through a modern manufacturing process so they make for a nice little package. On top of all of this, iRobot provides a serial interface by way of a 7-pin mini-DIN on top of the unit (this pin-out is the same as an 8-pin mini-DIN, so it's not so difficult to find a cable to work with it).

How do you use all of this? Well, iRobot has a developer page to get you started. From there, you can find information about the serial command interface (SCI). From the resources there, it's pretty easy to hack together serial interfaces to get up up and running programming the internals of your robot . . .

. . . HOWEVER, RoombaDevTools has done a great deal of the work for you. The two apps that I think are the coolest are the RooStick and the RooTooth.

So RoombaDevTools gets you right up and running with documentation, hardware (including cables), and software as well as lots of other helpful stuff. PLUS most of the importnat software is either platform-independent (i.e., Java libraries made for the JVM) or provided for OS X, Windows, and more. IN FACT, a common application is to combine a Roomba with a control system built on top of a GumStix. That's WAY cool.

So there ya' go... The Roomba(+Gumstix, perhaps) -- the next affordable robot development platform.
