Isolated...

With the recent departure of my boss Dave, I am now the only software monkey in Yahoo's Santa Monica Colorado Center. There are art directors, flash animators, HTML designers, project managers, product managers, bosses, bosses' bosses, bosses' bosses' bosses, and me. My Nerf weaponry is no match for their battle-hardened armor of bureaucracy.

And as though this office weren't isolated enough, the Internet is now broken. This multi-squillion dollar web company maybe didn't pay their internet bill this month, cuz all of a sudden, my "productive and essential Internet research" is at a standstill pending network connectivity. My one remaining option is to perform my duties using resources available on the intranet, or within arms reach. I think I'll go fetch some hot chocolate.

*sigh*

What were they thinking?

I just disassembled Roo's Mac iBook G3 600MHz to install a new hard drive. I do not use the word "disassemble" lightly. The path to the heart of this iBook is fraught with many screws. It felt like 600, though it was probably more like 70.

It is interesting to note that its nearly impossible to reassemble something of this complexity without overlooking a few screws, or installing a few too early that should have been held out for later. In this case, the number of screws left over is approximately equal to the total number of screws in most laptops.

They definitely weren't doing any good anyway. They were just deadweight. And so I can feel proud that I have not only replaced a dead 30GB hard drive with a roomy 90GB hard drive, but also streamlined the entire machine.

This guide made it possible.

Where to get the coolest toys ever

I just found Spark Fun Electronics last night, and I gotta say they've got the coolest assortment of green crunchy doodads I've ever seen. I spent an hour last night just perusing the catalog, and reading datasheets. I wish I was better at this stuff.

Among the very coolest things available are the GPS eval boards, cellular eval boards, and my favorite project that will never get finished: gyro breakout modules.

Oscilloscope

Today I bowed to the forces of consumerism and purchased... an oscilloscope. I found the Velleman HPS-10 for an excellent price at Omnitron Electronics. There's that link in case you're interested in buying one of your own. They're shipping it UPS ground from Florida. Yuck.

Every review I've read of it says that its a toy, and its just no damn good, etc. But that's okay, because as an electrical engineer I'm no damn good, and besides I'm making toys.

I'm a big fan of DIY approaches to these sorts of problems (which may explain my lack of overall productivity). I spent a full half-hour investigating the possibility of using my PC sound-card as an oscilloscope. I cut that line of inquiry short however when I realized that this DIY approach would likely result not only in frustration, a ongoing lack of oscilloscope, but also a busted sound card.

This HPS-10 oscilloscope (over which I've gotten myself into quite a shopper's frenzy) is shattering my long held notions about oscilloscopes: Oscilloscopes are big, expensive, boxy items sized to hold all those flux capacitors and thermal-bypass fuses and captured eigen-hamsters. This is a handheld device, and is noteworthy perhaps only insofar as it comes packaged in plastic bubble pack.

I want to examine triac outputs for bias, make sure my 555 timers are ticking, and my crystal oscillators are oscillating, and my piezo elements hear me drumming. And I don't want to take up room on my desk for a tool I know will be used rarely. That said, why doesn't it get here already!

The coolest bus ride ever

I'm prejudiced against busses in Los Angeles. They're packed, they're smelly, and they're slow. When I lap a bus on my bike on a sunny day, I always hope that some observant soul within realizes that there's a faster alternative.

But I took the coolest bus ride ever last week.

This is a Big Blue Santa Monica bus, and it stops right outside my office. I had heard vague mention of a bus that goes from Santa Monica to Union Station on the 10 Freeway. I was running late, and I knew that biking across town would take easily 1.5 hours. So I decided to take a risk and catch this mysterious Big Blue Bus.

And sure enough, it rolled into the stop right on time at 7pm. It wasn't packed. It wasn't smelly. It was half full. And everyone was talking with one another. Greeting one another as they got on the bus. Greeting the bus driver by name. The bus driver was ushering people to their seats, for gods sake! It was like a non-alcoholic episode of Cheers.

The next person to step on the bus was a friend of mine, Thomas. I didn't expect to see him, but I'm glad I did. He gave me the low-down on this particular bus line as we pulled away from the stop.

Everyone who takes this bus takes it every day because there is simply no faster way to get to Downtown. And so everyone knows one another. And everyone knows Von the bus driver because something of a distinctive individual, who happens to drive very fast.

Thomas takes this bus because he has to catch a train at 8pm. If he misses it, the next one departs at 10:30pm. He missed it once... Von took him out to dinner while he waited.

8pm? I got on this bus at 7pm. Was I supposed to believe that this bus was going to get me across town in less than an hour?

We're approaching the freeway, having made three intervening stops, and Von turns and asks Thomas "Mr. Thomas, may I have a timecheck please?"

"7:15, Mr. Von sir." replies Thomas.

Von gets on the loudspeaker (Von loves the loudspeaker) and says "Ladies and gentlemen, welcome to Line 10 Freeway Express. Our estimated arrival time at Union Station is 7:50pm. Please put your seat backs and tray tables in their full upright and locked position and prepare for takeoff. My friends, lets go home. By God, lets go home." And with that, we rocketed onto the freeway.

I was not aware that a bus could slip through traffic like a Miata, but that's exactly what Von managed to do. I never felt unsafe, and I don't think we were going too fast, but we were definitely moving faster than all the other vehicles around us. Without a bus lane.

Von announced over the loudspeaker that we would be landing in downtown in four minutes, and to please return to our seats. As we drove through downtown, Von would turn to people he didn't recognize and ask "Where are you headed?" And between frequent time checks with Thomas, he would alter his route to accommodate people's destinations. We arrived at the station with seven minutes to spare. I pulled my bike off the front of the bus and cycled to the Smashlabs.

Total transit time: 1 hr.

Los Angeles just got a little smaller.
