Disney, day 2: Animal Kingdom

For our first real vacation day, we went to Animal Kingdom. It’s the largest park in terms of area, but it has relatively few things to do. We started off with an invigorating shuttle bus ride, then made a beeline straight for the safari ride, which is basically an open jeep you ride on a track through a zoolike area. We saw several elephants, a group of giraffes, some Thompsons’ gazelles, a few oryx, a batch of hippos, and a lioness. Matthew was entranced, especially by the elephants. This was Arlene’s favorite ride. We also went for a walk on the Pangani Forest Exploration Trail, where we looked for (but didn’t find) the legendary white-bellied go-away bird.
Next, we wandered over to the Asia section and the Kali River Rapids. Matt and I sat this ride out, since a)I didn’t want to get wet and b) Matt was too small. The riders were unanimously thrilled with it. After a quick snack, we went on to see It’s Tough to be a Bug. Mom and the older boys loved it; Matt spent the whole time with his face buried in Arlene’s shoulder. David and I rode the Dinosaur thrill ride, which he said was “so turbulent” that it “aggravated his motion sickness”. Indeed. So, here are a few pictures:

Disney, day 1: travel day

So, yesterday we packed our stuff and set out for Disney World. It was snowing.
We got to the airport about an hour earlier than I would have if traveling alone—a wise precaution given that we had all three boys. Checkin was uneventful, but then we hit the first of several travel snags: our inbound aircraft from Cincinnati was delayed due to weather. It arrived about 20 minutes late, and we hustled aboard. Then we had two rounds of de-icing, which the boys liked pretty well (we told Matt that they were spraying the plane with orange juice to make it sticky). Bobby Brown, the flight attendant working our flight for ACA, was bar none the friendliest, most cheerful FA I’ve ever had, anywhere. His boss is getting a glowing letter.
Our flight to CVG was bumpy, and we got there just in time to board our connecting flight to Orlando. Borrrrring, smooth flight. The real fun began when we got to Orlando: our luggage wasn’t there. The DL ramp folks in TOL hadn’t loaded it because our aircraft was overweight. I guess they figured bumping luggage for a party of six was better than bumping three sets of two, or something. Anyway, I didn’t find that out because Thomas and I had gone to the Budget car rental counter. Imagine this scene: a 50-foot-long counter with about 15 computer terminals and 17 people in line… manned by two rental agents. When we finally got to the head of the line, the very helpful agent fixed up our reservation and arranged to have an Explorer for us, so I went back to baggage claim to check on our bags. DL promised to have them delivered to the hotel. (They eventually arrived around 11:45pm, festooned with big red “VIP” tags. Evidently “VIP” in Delta’s lexicon means “leave off airplane”). We trooped out to the parking area and boarded the Explorer, which turned out to have a defective airbag. Oops. Back to the rental island, where they instead gave us the minivan that I should have reserved in the first place. (All this way to take an exotic vacation, and what am I driving? A minivan. Sheesh).
We found the hotel easily, unloaded our carry-ons, and walked across the street to Downtown Disney. I have some good pictures of Matt with Buzz Lightyear and the older boys at the Lego store, but they’ll have to wait until everyone else wakes up and I can find the camera. Everybody remained really cheerful and flexible throughout our travails yesterday, which I appreciated greatly.
This morning, our plan is to hit Animal Kingdom early to ride the safari ride, then see Legend of the Lion King and some of the other live shows (because I’m in a hurry now I’m not linking to any of the Disney pages for these; you can find more links here

The switch is done

Yesterday, I spent about two hours giving Dish the boot. I pulled down the two-LNB Dish 500 dish and replaced it with a so-called “phase III” DirecTV dish. That was easy; it actually took me about 15 minutes to hang and align the dish to receive good signals from all three satellites. Then I spent the next 45 minutes (no kidding) on the phone with DirecTV, activating my two receivers. There’s a Philips DSX40 TiVo in the living room and a generic Philips DSX5500 down in the basement. Why the basement? Well, since it’s connected to the old TiVo, the new receiver can feed a signal to the bedroom TV or to my flat-panel, which faces the treadmill. Voila! Instant treadmill entertainment. What do I like and dislike so far?

MS announces NAS & iSCSI support for Exchange

In a press release today, Microsoft announced that they’ll be supporting iSCSI and NAS devices for Exchange. The PR doesn’t mention any specific devices or vendors, merely that devices that are logo-qualified for the Designed for Windows logo will be supported. We’ll have to wait and see what “supported” means in this context.

Plaxo considered insecure

I’ve never been much on centralized contact managers like Plaxo. Why would I want to outsource all of my contacts to some company in the naïve hope that they won’t hose me? Turns out that this may have been a legitimate concern; this describes a trivial script injection attack against Plaxo that lets an attacker 0wn your contact data. Oops. So, if you’re using Plaxo, you should probably stop.

Stop the madness

I keep seeing hysterical reports that Bill Gates wants to impose e-mail postage to stop spam. A quick Feedster search for “gates spam postage“, for example, turned up 90 posts. Most of these are based on this CNN/AP story .
Unfortunately, virtually all of the articles and commentary miss the point: Microsoft’s not calling for people to pay money for postage. Instead, they’re floating the idea of using a hashcash-like system that requires the sender to perform a calculation (something like a hash of the message plus the sender’s address, with some additional crypto thrown in) before sending the message. The MS Research system (described somewhat here) uses a similar idea: if you require a certain amount of computation to send messages, that raises the cost to people who send out millions of messages, i.e. spammers. (Interestingly, the BBC article says that Cynthia Dwork, who first floated the idea of computational-postage systems in 1992, is now working at Microsoft Research. Her original paper, here, makes for interesting reading).
Now, here’s the part that most people are missing in all the “Bill Gates wants my postage” kerfuffle. If the message doesn’t have a valid hashcash token, it can be passed through a normal spam filter. . In other words, if it has “postage” (which is created by burning a few CPU-seconds on the sender’s machine), it can be directly accepted (or not), but if it doesn’t have “postage” it gets the full proctologist’s treatment with SpamAssassin, the Exchange IMF, or whatever. (n.b. Ecto‘s spellchecker recognized “proctologist’s”– pretty cool, huh?) This is exactly analogous to what we all do with postal mail: if I get something that was mailed bulk rate (thus lacking “postage”), it’s much more likely to get canned.
Microsoft is not suggesting that we pay actual cash for any of this (although these guys, and others, are). Calm down, everybody. Considering that there aren’t any viable micropayments systems (and yes, I include Peppercoin in that dismissal), the idea of requiring actual micropayments for email is laughable, and no one knows that better than MS. However, a hashcash-like system is a useful adjunct to (not replacement for) other filtering systems. In fact, there’s already at least one hashcash implementation, FirePay.

Exchange Edge Services

Last week, my column was on the forthcoming Exchange Edge Services product. Microsoft hasn’t said much about it publicly yet, but it’s pretty clear that they have two goals: provide a hardened subset of Exchange functionality for use on the edge, and displace Sendmail/postfix/qmail in shops that have Exchange at the core but not at the edge. Whether they succeed or not will have a lot to do with how they position Edge’s capabilities. Personally, I’m really excited about the prospect of being able to build my own services using managed .NET code– that approach offers a lot of potential over the current event sink model.

The return of Wacky Packs

70s flashback alert: Wacky Packs are coming back! I can only imagine how happy David and Thomas will be once they become acquainted with the happiness that comes from stickers that parody popular consumer products. I remember eagerly collecting these and plastering the stickers over my school notebook, various toys, fixed structures in and around our house, and (when no one was looking) several of Julie’s toys. I wonder if they’re taking nominations for products to “feature” in the new series?

Mercury redux

So, the mercury posse came back today with a Lumex, a mysterious device whose noise level is only exceeded by its cost. It’s basically a portable mass spectrometer that can be used to measure extremely low levels of mercury. The State of Ohio standard is less than 1 µg/m3. In the breathing zone, our levels were lower than that, but inside the affected cabinet and on the floor beneath, we were around 1.4µg/m3.. So, according to the health department, we’re still contaminated. Time to call State Farm and give them the good news: at minimum, we need to replace the affected cabinet (which of course means we’ll probably have to replace the others, since matching a 12-year-old cabinet set is unlikely) and the contaminated section of floor. Since the floor is 12-year-old sheet linoleum, it’s probably going to have to be replaced too. What the hey, let’s remodel the kitchen.

Go, CajunBot!

The University of Louisiana-Lafayette has a team in the DARPA Grand Challenge: Team CajunBot. The goal: build a vehicle that can drive itself, with no human intervention, from Los Angeles to Las Vegas. (Be sure to check out Clotile, their mascot). Their team journal is here— I’ll be following it regularly.

Sparklines

Edward Tufte has a terrific new information visualization concept: sparklines, small word-like graphs that compress data into easily readable trends without using measurement units. This makes me want to write some code.

New developments in church

First there was Bedside Baptist, where my sainted Aunt Betty attends regularly. Now Mike reports that there’s iChurch, brought to you by those wacky folks at the Diocese of Oxford, Church of England. Their mission statement sounds good (“One of the key purposes of i-church is to provide a community for those who do not find participant membership of a local church easy, and it will therefore reflect an inclusive attitude to Christian faith and discipleship.”).
In another church-y development, at least one church now has WiFi in the chapel. James Tallent reports that his church has added WiFi, then he blogged this Sunday’s sermon while it was happening. An earlier post of his has this to say:

Beyond these use cases, SMS addiction is already a reality and IP-related addiction is not far behind. Some would say that churches should shun accommodation of such addictions and require everyone to be somber, disconnected, and reflective in church, but that will frankly be just as silly in the future as it would be now to say that free coffee and coke machines are encouraging caffeine addiction.

Put me squarely in that camp. The whole point behind going to church is to be reflective. If you’re sitting there checking your email, IMing your friends, or (heaven forbid) working, it seems to me that you’re missing out on an opportunity to put things of the world aside and focus– just for a little while– on spiritual things. Don’t get me wrong; I do think it’s incredibly progressive to provide this service– but is it progressive in a positive direction?

Today’s cheap shot deconstructed

So, Ed Brill has been reading the Exchange team blog, probably for much the same reason that Microsoft PMs read his blog– know your enemy, and all that. So, let me leave aside the fact that it’s disingenuous (and, IMO, slimy) of Ed to say “I’m not spinning, but $spin…” and point out one key difference between IBM and Microsoft’s support programs.
With Microsoft, any customer with a credit card can call Microsoft PSS and get support for any active product. If you want to buy a support contract, fine, but if you don’t, you can still get support. The PSS org thus has to be sized for variable call volume from an unpredictable mix of 5.5, 2000, and 2003 customers, calling at unpredictable intervals. As far as I can tell, the only way to get any support from IBM (apart from their relatively useless support forums) is to buy a Passport Advantage contract, pricing information for which isn’t publicly available. This gives IBM a pretty good way to predict required staffing levels, given that they know exactly how many customers they’re obligated to support.
It’s an interesting tension: limiting your support to contracted customers helps screen out a large percentage of customers, who are then hosed when they do need support, but that smaller support base means you need fewer support engineers, who will generally have lower utilization. Of course, MS would hire more PSS engineers if they could; in fact, they’re aggressively hiring for the Exchange support team, but the skill bar is pretty high, so it takes time to fill the open positions.
Ed and I are in agreement on one thing, though: it is refreshing to see the blog-driven openness that is slowly permeating Microsoft, IBM, and other large companies. (Well, we agree on two things: AT&T’s new upgrade program stinks.) That openness is all the more refreshing when it’s factual and technical, not just more marketing spin and hype.
Update: Ed was kind enough to link here from the comments to his post, in which he points out that edbrill.com isn’t an IBM web site. That’s true, and I should have made it more clear that Ed is of course speaking only for himself, so I retitled this post slightly.

Your tax dollars at work

Public service announcement: if you have any mercury thermometers in your house, dispose of them properly now. If you don’t, one of them might break, causing a spill and necessitating visits from the Wood County Health Department, the Ohio EPA, and a (really expensive) environmental cleanup posse from EQ. Mercury vapors are toxic, and the stuff vaporizes at 55°F, so one of the things they’ll bring is a sniffer that will tell you whether your house is fit for habitation or not. You’ll also get an Ohio EPA incident number, which is sort of like a scarlet letter except that it’s not scarlet.
Update: the posse is here, using their special mercury vacuum. They are very thorough and quite pleasant.
