Prove It

Tuesday, November 13th, 2007

In various interviews, there’s been a split between the people who believe what you say on your resume and those who seem determined to make you prove it. The latter takes multiple forms. Technical interviewers have asked me various verbal questions, from explaining programming concepts to specific problems in specific languages. I walked into one face-to-face interview and was immediately handed a two-page written quiz, reminiscent of my CS 101 days. In another, after talking for about an hour, a developer sat me down in front of a computer and let me spend half an hour putting together a web front end for one of their database tools.

I tended to do the best in the last of those situations, since it was the closest to real life - write something practical while using your innate knowledge and the usual references you have at your disposal. I was less of a fan of the theoretical; I tend to know what works and only delve into the underlying basics when they stop working.

Of course, I tended to gravitate more towards interviewers who placed a little more faith in my background, and felt it out by asking about the details of previous projects. There were also some good questions asking my opinions of various technologies; these also tend to expose whether you’ve worked with something enough to understand it’s true advantages and disadvantages.

The New River to Lamanai

Sunday, November 11th, 2007

Jesus Christ bird - walks on waterSwooping down the New River in a small boat banking big turns through the jungle conjures up any number of Heart of Darkness and Apocalypse Now flashbacks, but our captain and guide Carlos soon cuts the motor so we can stop and watch the “Jesus Christ bird” walk on water. (Or lily pads, for the less faithful.)

Boating down the New River to LamanaiWe’re enjoying the hour boat ride to Lamanai, the largest Mayan city in Belize. The original tour we booked through the Hotel de la Fuenta canceled on us, but the owners continued to take great care of us by getting us another one and even driving us down to the dock. In addition to my Dad and I, there’s a group of 10 who have already traveled 2 hours by boat and bus from the island of Ambergris Caye we left the day before.

Ephiphytes - plants growing on other plantsThe river is less active midday than earlier or later, but we still see various plants and animals. A crocodile even splashes the boat, giving me a faceful of water, but not a chance to even realize it was a croc. Lunch for us is the traditional spiced stewed chicken over beans and rice; then we quickly become lunch for the mosquitos. My legs are safe under long pants, but my hands and arms are soon streaked with blood from fending off the little buggers.

Howler monkeyLamanai is worth the sacrifice, though. In addition to a number of restored buildings, walking through the jungle begins to give us a sense of the ecosystem that thrives here. Howler monkeys and toucans own the trees, while the forest continues to own 98% of the known but unexcavated city buildings.

Dad and Matthew celebrate the end of the climbThe Tall Temple offers a steep climb to a panoramic view 125 feet above the surrounding rainforest, and most of the group takes at least a stab at it. It’s a welcome escape from the bugs, and there’s a healthy exchange of cameras for “summit” photos.

The jaguarAfter walking through the royal residential area and past the jaguar temple, the tour wraps up quickly, but most of us are happy to get back in the boat and enjoy the wind in our faces and cold drinks in hand.

Chicken Plane

Sunday, November 11th, 2007

Window seat on the flight to CorozalBefore we got on the Chicken Bus in Belize, we had to catch one of the quick local flights between Ambergris Caye] and the mainland. Never mind “puddle jumper” commuter planes; these were almost down to the scale of the bush plane I took to see [Mount McKinley in Alaska.

The contrast of the airport was one of my favorites: there’s nothing like boarding on a jetway and deboarding by stairway to remind you that you’re a bit off the beaten path. The island terminal is just a few buildings with open-air waiting areas; the baggage claim area is a spot in the grass where they park hand-wheeled carts piled with bags.

The local airport security had picked up on the TSA’s shoe fetish, but didn’t seem too concerned with baggies of 3 ounce containers. After climbing, almost literly, over the seats to your own sheep-fur-covered spot, it was simply time to go. No safety lecture, no shutting off your electronics, not even an admonition not to reach out and grab the controls that were in arm’s reach, certainly no queue on the taxiway - just a quick shoot down the runway.

AirstripThe flight was only about 20 minutes, and at only 200 feet provided some nice views and photos in the daylight. Approaching Corozal, I tried to reconcile the guidebook’s description of it being a regional economic center with the limited sprawl of two-story buildings. Then we lined up with the runway; more of a paved strip in the grass. It was a smooth landing, but it still felt good to be out of the small plane and back on solid ground.

RFID Cat Can Has Tinfoil Hat?

Sunday, November 11th, 2007

Meadow got spayed on Friday, and during the procedure, they also implanted her with the Avid Microchip Identification system for animals. I knew this was one use of RFID chips, though I didn’t realize it had become a common veterinary practice. Since Meadow’s an indoor cat, she doesn’t wear a collar, so it’s nice to have some extra insurance.

Of course, the geek in me wants my own cat scanner, even if all I’m going to get is some ID number. The Flo Control  guys could certainly do some interesting things with it…

Why Engineers Make the Best Patients

Sunday, November 11th, 2007

From When the Patient Is a Googler :

Susan got me thinking about patients. Nurses are my favorites — they know our language and they’re used to putting their trust in doctors. And they laugh at my jokes. But engineers, as a class, are possibly the best patients. They’re logical and they’re accustomed to the concept of consultation — they’re interested in how the doctor thinks about their problem. They know how to use experts. If your orthopedist thinks about arthritis, for instance, in terms of friction between roughened joint surfaces, you should try to think about it, generally, in the same way. There is little use coming to him or her for help if you insist your arthritis is due to an imbalance between yin and yang, an interruption of some imaginary force field or a dietary deficiency of molybdenum.

Not only that, we can fix your broken diagnostic equipment:

(One of our keynote speakers at the MCES conference played this to a very receptive crowd of engineers.)

One Bump in the NetBank-ING Transition

Sunday, November 11th, 2007

I previously wrote how pleased I had been with ING’s purchase of NetBank after FDIC Shuts Down NetBank Due to Defaults. One hurdle I was waiting to see them clear was transferring all my online bill payment information.

They decided to punt on that one, and just convert NetBank Checking accounts into ING Savings accounts. Which is bit lame, given ING has a paperless checking account they claim lets you pay anyone. I created one of those on my own, and moved the few repeating payments I had setup; the rest I’ll add as the bills come in. It’s a minor inconvenience, though not bad considering my bank did go belly up. The new account is actually pretty slick: send anyone a paper check, an electronic funds transfer, or pay a bill.

Diving in Belize

Saturday, November 10th, 2007

The reason I choose Belize was for it’s renowned scuba diving, and I certainly wasn’t disappointed. Boasting the second largest barrier reef in the world, it has abundant easily-accessible reefs filled with healthy coral and fish. It has some big name sites like The Blue Hole and The Elbow, but the former didn’t seem worth it, and in the slow season there weren’t many boats running to the latter.

Ocean viewDiving the local reef off Ambergris Caye was a pleasure, though. Each morning around nine, the dive boat would make a pickup at the dock in front of the hotel and take a calm 10-15 ride out to the reef. After a good 40-50 minute at 50-80 feet, we’d head back to the dive shop’s dock for a tank swap and surface interval before doing a second dive and getting dropped right back at the hotel. That left the afternoon free for lunch, napping, and lounging in a hammock, making for some very pleasant days.

The water was a warm 84 F, even at depth, so I was quite toasty in my 3mm wet suit; most people went with a thinner shortie. There was plenty to see in addition to the variety of coral and tropical fish: nurse sharks, groupers, an eagle ray, and a few eels Dad developed a specialty for spotting. The coral itself also boasted some deep canyons that were quite dramatic to swim through.

Eagle ray in flightThis was the first trip I did any dive photography, which opened up a whole new world: looking for good shots, getting better bouyancy control, and mastering a little more multitasking. I also rented a dive computer for the trip, which allowed me to get in much more diving that using tables, and took the mathematical work out of my dive vacation.

Chicken Bus

Saturday, November 10th, 2007

Belize was my first really good local travel experience on the chicken bus (yes, of course it has a Wikipedia entry!). Arriving at the airstrip in Corozal, the taxi driver in Corozal was happy to take us to the bus stop, but for 10 times the bus fare, also offered to drive us directly to Orange Walk. We stuck with the bus plan, despite the fact that the original bus company had gone bankrupt and there were no tickets being sold at the stripped-down bus terminal, just a vague promise that a bus would show up.

After watching the local mid-morning color for about half an hour, a repainted Bluebird school bus rolled up. The “conductor” hopped out, yelled out some destinations, and confirmed ours was among them. All the windows were down, and Spanish music played at a healthy stereo and lights system that I don’t remember from my school bus days. The bus filled up with local folks (but no chickens) and a young American couple backpacking - her oversized sunglasses and his trucker hat didn’t leave much doubt as to their origin.

The bus barely made it’s first turn before stopping to pick someone up, in what quickly became obvious was the standard “route”. The conductor collected fares ($4 for an hour’s ride) and then hung out in the open door of the bus collecting and discharging passengers from seemingly random spots along the road.

Our destination was equally distinctive: the hot bustling market of a moderate central american town. Lugging our bags from there to the hotel showed us most of what Orange Walk had to offer, and after the ride, we were glad to grab some lunch and hide out for the heat of the day.

Flat Tire

Saturday, November 10th, 2007

Rain on the plane in PhiladelphiaWinter warm spells, monsoon rains, and hay all over the Schuylkill - it seems weird things happen every time I try to leave from the Philly airport. Heading to Belize, it was monsoon rains, and when I found my Dad at the check-in counter, we were already in danger of missing our connection to the one flight a day into Belize City due to the rain. We took it in stride, though, and were ready to run as the plane pulled up to the gate in Dallas.

Everything’s bigger in Texas, and the airport is no exception. Our connection was naturally the farthest possible gate, so after our hustle we were pleasantly surprised to find the plane still there. As we settled into our seats, we found out why: the plane had a flat tire was going to have to be replaced, delaying departure about an hour. The guy sitting next to us looked over and said, “I bet you’re the only two happy ones on the plane.” And we certainly were; the delay meant we actually had time to go back into the terminal and get some lunch!

Belize Photo Notes

Saturday, November 10th, 2007

Matthew concentrating on a photoMy recent trip to Belize was my first big vacation with the DSLR, and an undeniable slip down the slope of photo obsession. My carry-on bag basically consisted of the following:

  1. Rebel XTi with kit lens
  2. 50mm f/1.4 prime lens
  3. Canon SD630 point and shoot in waterproof housing

Over the week, I shot about 1000 photos, 300 of those underwater while scuba diving, and 50 taken by my dad with the same underwater camera.

Big palmsThe biggest surprise for me was never using my prime lens. For outdoor shooting of landscapes, the kit lens’ wider zoom was an obvious choice. And for macro work, it focuses at a closer range to provide a fuller frame. It’s one shortcoming was the high f-number; shooting in dimmer light under the jungle canopy was a struggle. Sometimes I had to resort to the flash, though I never thought to employ my flash diffuser. That begs the question of a lower f-number upgrade, though Digital Photography School’s post on Travel Photography - Which Lenses to Take? doesn’t offer any runaway solutions to me.

Jaguar TempleAnother piece of equipment I didn’t use was my new 50mm lens hood. After anticipating the strong Central American sun to be a lens flare problem, I purchased it for the trip, naively thinking it would also fit the kit lens. Of course, it didn’t so a few of the Lamanai photos have a bit of flare.

Overall, carrying around either camera wasn’t bad; the only difficulty was having my LowePro shoulder bag swinging around when scrambling up to the top of the unexcavated Mayan temple at La Milpa. (I do have a waistbelt for the pack, which would solve the problem.) Having add-on pouch for a water bottle was also a life saver, though with a big bottle and no camera, the bag was a little unbalanced.

Post-processing and trimming the photos was surprisingly quick over the course of two days. I’m getting much better about making the first cut of interesting photos from everything I shot. The second cut is tougher, trimming near duplicates and otherwise good shots that just don’t add to the album as a whole.

Life on the reefMy one disappointment was the inability to get good color correction when post-processing the underwater photos, though people still thought they were pretty neat, so I guess I shouldn’t sweat it. Next time, I’ll try using the flash to get more balanced colors. Overall, though, it was a great trip for photography!
