There should be some sort of alert for this

Whoa! I had just opened up the LOA stats to show my parents the curious effect that the subway map had on our hits (as I remarked in a previous post), and found that it has exploded to become an order of magnitude greater than before. Whereas we used to get nearly 400 hits a week, we’ve been recently averaging more than 500 a day. This is all very curious, but it seems to really take off a few weeks after my post remarking on the initial effect. I took a look at our most popular search terms (still “New York Subway” and “New York Subway Map”, and still accounting for 99% of hits), I found that our picture of the subway system actually came up second on Google Image Search for both. I wish I’d done this just a few days earlier, because it seems possible that our recent slump could be caused by a bump from the first place spot. Damn that stonesoup.org!

Anyway, it looks like the attention doesn’t extend far beyond the post that started it all, though it’s impossible to tell if people are perusing the main site, or getting RSS feeds (and being sorely disappointed out our output). Still, I’m going to enjoy my little internet fame. In fact, I think I will use it to start a user-content driven web 2.0 crowdsourced social networking app.

And by that I mean, if you’re looking for a friend (social netwoking), leave a comment with your favorite movie (user generated content). If you see a pair of compatable looking movies (2.0 of them, to be precise), email me (crowdsourcing) and I won’t do anything (I’m still working on the app part).

Happy holidays!

So, what are you doing with your year off?

Thursday, December 27th, 2007

The worst part about being a LOAner (one of my goals this term is to get an arbitrary term into the common lexicon) is constantly answering the question “So, what are you doing with your year off?” and its variants “What have you been up to?” and “Which one of your family members is going to support you when you’re unemployed and living on the street?”

It’s a perfectly reasonable question to ask. If I tell someone that I’m studying Systems engineering (“It’s a combination of mechanical and electrical- sort of half a double major”) at a small but respectable accredited engineering college in Massachusetts, they would have a concrete, albeit probably inaccurate, concept of my past, present, and future. There are even some year off options that are pretty well understood, like doing an internship or traveling. They are considered intrinsically noble pursuits, and don’t require too much more explanation.

Because I don’t have any one theme to tie up the semester, my answer becomes a Choose-Your-Own-Adventure. Like all chaotic systems, the conversation is extremely sensitive to initial conditions. If I’m feeling up to a longer conversation, the mention the web startup that I’m currently working on. Naturally, this leads to endless questions about what it does and how (I will be posting about it as soon as I get some of the final basics settled.) The medium-length solution is to get into the Solar Decathlon, and hope that if I tell them enough stories about things I have done, they’ll forget to ask about what I’m currently doing. Finally, I could deflect the question by saying “Oh, pretty much just hanging around”. In my experience, this will generally kill the conversation after a few more awkward exchanges .

It’s still better than having to lay out why I was in Washington DC on the MIT Solar Decathlon team, at which point I generally have to remind them that I don’t attend MIT- I just live there and build altfuel cars and houses with them. Then it turns into a discussion of why I chose Olin, and what Olin is in the first place. Which defeats the purpose of a medium-length solution.

I do enjoy telling people about what I’m doing, where I’m staying (I <3 pika), and why attending Olin while taking advantage of the extracurriculars at MIT is the best deal in the world. But I’ve found that coming home has required me to repeatedly tell the story from the beginning (“I was at my high school college fair, and there was this one little college that nobody was paying attention to, so we went over to check it out….”) It gets old after a while. But I guess that if you wander a bit off the beaten path, everyone’s going to wonder where you’ve been, and if you fought an angry bear.

For the record, I haven’t fought any bears, but I met a massive (or, as Ben would suggest, giant) beaver…

Turkey Squirts – A New Tostado Thanksgiving Tradition

Saturday, December 22nd, 2007

First off, let me say that Turkey Squirts are now what you get for eating too much on Thanksgiving. Rather, Turkey Squirts is a themed layered shot for Thanksgiving created by my dad, Jim Tostado.

Turkey Squirts (3)Turkey Squirts

Let me breakdown the recipe:

Start with 1/3 shot of Kahlua, then on top of that add 1/3 shot of Bailey’s, and then 1/3 shot of Wild Turkey (the namesake of the drink). Then add a small floater of Bacardi 151 to the top and light it on fire. Once the drink is flaming, sprinkle cinnamon over the top for a few seconds, enjoy the fireworks, blow out the flame and then consume! Simple enough and quite tasty.

Turkey Squirts (2)

Relatives of mine who tried Turkey Squirts this Thanksgiving described it as “an aftertaste like eggnog”, “holy crap”, “that was hot”, and “can I have another?”

Tim: yay campaigns

Saturday, December 15th, 2007

I only spent 13 hours at work today and it made me really happy. Also, Antonio Villaraigosa is pretty much awesome.

My daily caffeine intake is trending towards “probably unhealthy,” with ambitions of achieving “mildly alarming.” I have a firm new appreciation for espresso and also of the Starbucks conveniently located between the house where I’m staying and the campaign office.

Livin’ the dream!

The semester in a quote

Nerd Aprons, Anyone?

Saturday, December 8th, 2007
Influenced by my nerdiness, Auntie's Aprons (my mother's apron business) has come out with a new product that may appeal to a more non-traditional crowd; particularly, nerds that like to cook. That's right, a circuit board apron and matching hot pads!







I particularly love the hot pads. They make me want to get out my soldering iron and solder on some surface-mount components!

Now, this is the first attempt at nerd aprons, so let me know what you think. Are their other nerdy fabrics that you would like more than a circuit board? Do you like the idea, but something is just not doing it for you? Then, what would? Any ideas or suggestions would be greatly appreciated!

Tim: Tucumcari, New Mexico

Friday, December 7th, 2007

Hello from Mountain Time. I have photographic evidence that there are many cows in Oklahoma. Also at that link: photos from the Clinton library!

I picked up an audiobook copy of Giving at the Clinton museum store (more on the store in a coming post) and Sondy and I listened to it in the car today. I wasn’t really what I was expecting — it’s v. much an inspired laundry list of ways to do good things in the world, and of people who are doing good things. Useful and practical, certainly, but not a ton of insight into Clinton’s life, presidency, or plans. A good listen, though, and it’ll have me thinking about giving for a while now.

Tonight, we’re in New Mexico. The motel feels very Edward Hopper. That is all. Good-night!

Tim: Hello from Memphis!

Friday, December 7th, 2007

Good morning from Memphis, Tennessee! I’m road-trippin’ it across the country to Las Vegas, NV, which is where observant Planet Olin readers will have noticed that I’m going to be working for the Hillary Clinton campaign from now through January. More on this later, probably.

It turns out that Virginia is a bigger state than I thought it was, particularly when you’re heading out the very southwest corner of it. It’s been a good drive so far; the scenery was all very pretty but nothing surprising. Tennessee is sort of like an east-west New Jersey, in that it is long and in my way.

Today’s plan: cross the Mississippi and crash the Clinton Presidential Library in Little Rock en route to Amarillo, TX. It promises to be an exciting day! Pictures tonight.

My Very First Application Note

Tuesday, December 4th, 2007
I have been working at TI for a little over 4 months and my first application note has recently been posted on the web! I created an application note and two supporting design tools in both Excel and Mathcad. The application note applies to the TPS6205x chips that are 95% efficient buck (step-down) converters and have Low Battery Input (LBI) detection, which is what the application not is all about.

If you are too lazy to actually read the application note or even the abstract, here is a quick run down: Batteries decrease in voltage as they loose capacity (but not linearly) and they have an internal impedance that lowers the overall voltage when current is drawn. The TPS6205x chips have a Low Battery Input (LBI) pin that you can set to shut off the system when the voltage is too low. The problem is that the internal impedance of the battery will cause the battery voltage to increase when there is no current being drawn. The chip will think it is back up and running because the voltage has gone above its threshold and turn everything back on. The system will continue to turn off and on, which is bad because your battery is still depleted and can't run your system. You only want the system to come back on when you have a fully charged battery powering the system. So, you add hysteresis to the LBI by utilizing the fact that the Low Battery Output (LBO) pin goes from high to low. If you want more details, really, just read the application note.

There is one aspect of my job as an applications engineer; writing technical documents that people might actually read. Makes me feel all warm and fuzzy inside. :)
