Productivity

I didn't really think about it until Child mentioned it, but a lot happened today.

1. My laptop was shipped today. Estimated TOA: Wednesday to Friday
2. Passed a potential (Spanish-speaking!) hire along to the animal shelter. They get a lot of Hispanics, including a lot who don't speak any English, so they really need a Spanish-speaker.
   
3. Got an appointment to get our neighbor's cat spayed. No more litters of kittens! Yay!
4. Talked Apple into giving Child an upgraded laptop for free, since her current MacBook has had so many problems. Now we can have new laptops together!
5. Got halfway through shortening my 80-page thesis into an 8-page journal submission. Not required, but my advisor strongly suggested it. Since he determines whether I graduate, I usually take his suggestions.
   

Vegetarianism

I don't like being an "every detail about my life" blogger (although I enjoy reading some). I usually only like posting when something I consider "eventful" or "interesting" happens, like canyoneering trips or thesis advancements.

Every now and then, however, it's nice to post an overview of what's been going on, more for my own information than anyone else's. It's turned out to be handy to go back to my blog to see when something happened, but for that to be useful, I have to have posted about it.

Last week Child and I visited an old friend of mine, and his wife and new baby. My friend informed me his wife would be cooking chili, so I asked if his wife wouldn't mind setting aside a bowl for Child before she put meat in, assuming it would contain meat. (Child is a vegetarian.) He doubted she would add meat, but assured me a bowl would be set aside if she did.

We get down there, and his wife assures us that there's no meat in the chili..."except for a few tiny bits that were the spaghetti sauce" which she added. That's like telling a Mormon "there's only a little alcohol in the drinks," or telling a Jew that "there's only a little pork in the stew." Believe me, vegetarians are just as serious as any religion.

I think it's just simple misunderstanding of what a vegetarian really is. Reference my earlier post about "vegetarian cookies," and even after my wife tried to explain the difference between a vegan and vegetarian, the clerk refused to believe her. Come on, she IS a vegetarian! She should know what one is!

Anyway, at my friend's house, Child quietly eats chips and cheese, the friends pretend not to notice that she isn't eating the chili (they're smart, they probably immediately realized that even a little meat was apparently un-kosher), and I take seconds to make up for Child.


On a different note, the thesis is going good. I'll be defending in May (did I already post that?), and the Boss wants me to submit a shortened version of the thesis as a journal paper. I'm also working on my resume, and the Boss said that as soon as my second committee member approves the thesis, I can start freelance work again. Yay!

Things are unraveling faster now!

The thesis is almost done. I've got the bulk of the writing done, and have submitted draft -1 or so to the Boss. The thesis defense will probably be in less than a month.

Along with that, I've been getting ready to go back into Job Mode. I've been sending out emails, telling contacts I'll be taking programming jobs, and have been looking into apply for jobs at Google, Amazon, and other smaller companies. I still need to decide exactly where I want to love; Child wants Texas, but I'm not sure I'd like the humidity, heat, and bugs.

A week ago I put together a website for the South Utah Valley Animal Shelter: suvas.org. The previous programmer hadn't done anything with it for two years, and it was only half-completed. Not to mention that the information that WAS there was outdated. I set up the website with Joomla, so the people at the shelter could update the website themselves.

After doing so, and showing them how to do it, I remembered why I didn't like doing that though. Joomla allows the user to update their own website, but it still takes a slight amount of technical savvy. That means it gets passed off to the "young 'un" on the staff, which means the pages end up looking like an email or text message. I might exaggerate slightly, but the pages are still full of misspellings, weird formatting, and other issues that make me wince.

It also makes it difficult to create a portfolio of sites to show other potential clients. The SUVAS site should be okay since I only showed them how to modify the text, not the "look 'n' feel" of the website, but I've done other sites where the owner would take over the website when I was done and completely trash it. Giant purple font, animated gifs dotting the page, messed-up tables, etc.

While I was at the shelter showing the staff how to edit the pages of their site, a man came in to reclaim his dog. It had been brought in when he had been taken to jail the night before, and he wasn't happy about having to pay money to get it out. Not that he wasn't used to it, "This dog's been locked up here before...and up in Salt Lake too...and pretty much anywhere I got caught." The guy was obviously a regular in jail, with no sign of ever changing.

Speaking of which, five of the "garden inmates" (inmates who work in the jail-run acre-wide garden behind the shelter) and their supervisor came in. They wanted some dogs to walk up and down the rows, hoping the scent woulds care off critters who were eating their seeds. We picked out six dogs for them, and I was pleasantly surprised when they actually came back with six dogs as well. With that many dogs in close proximity to each other, all excited about being outside for the first time in weeks, I sort of expected some attrition. :)

Thesis Project

I guess I've never really described my thesis project in detail, and since my wife recently heard a horror story about a husband who had been pretending to go to school for, like, four years before his wife found out he wasn't, I decided it might be wise to show a little bit of what I'm currently doing.

My thesis project, in short, is to show that letting a robot (well, 200 of them, in simulation) and an operator jointly decide the correctly level of autonomy (independence) results in them doing better (at a wilderness search and rescue mission) than if just the robots decided on the level of independence they wanted, or just the operator decided on the level of independence to give the robots.

(Officially: "Given a search task in a Wilderness Search and Rescue domain performed by a large heterogeneous group of agents, a mixed initiative system implementing both adaptive and adjustable autonomy performs better in a complex or high workload situation than a simply adjustable or adaptive system.")


This is the main window. The little yellow squares are the 200 robotic searchers, and the big yellow box is their current search area. At the moment they're on "Low Independence," indicated by their yellow color. If they were red, they'd be on "High Independence," which basically just means that they'd be creating their own search areas, rather than waiting for the supervisor to do it.



Somewhere on the map, there's a missing child. (Actually, there's five so we can average the length of time to find them.) The picture at the top is a picture of the kid(s), and the 16 items below him are his backpack items.


As the searchers search, they find items. Most of the items are "distracting" items, such as the three that they've currently found. If they look in the right place, however, they'll find the backpack items that the children lost as they wandered, which will let the supervisor narrow down their search and (hopefully) find the children.


I'm in the middle of having handfuls of experimenters come in so I can gather data, but I'm sort of simultaneously writing the thesis, at least the parts I can without actually having data.

As the initial results are showing, the scenarios where the robots make all the decisions take top marks in several measures (such as the amount of ground they can cover, and the speed of response when a backpack item is found), while the scenarios where the supervisor makes all the decisions takes top marks in several other measures (such as the number of backpack items found), but the scenarios where they jointly make decisions comes a close second in MOST of the measures.

So it's a tradeoff. What measures are the most important? And are you willing to sacrifice being best in a FEW measures to be second-best in a LOT of measures?

Busy Busy Busy!

Wow, there's a lot on my plate right now. Let's summarize, shall we?

1. Thesis! This is actually my top priority right now. I'm at the stage where I'm a little stuck, and need to do some thinking about exactly what data I want to collect, and how I need to arrange the experiments to get it.
2. Finishing up the Utah County Pets website. If it weren't for the snowstorm outside, I could go down to the animal shelter and finish most of the stuff up. Soon enough, though.
3. Business idea. I have a product that I think would be interesting to produce, but no idea where to start and no time to do it, even if I did know where to start. However, as soon as I get time and really want to start on the project, I have a few relatives who'd be good resources, and I actually have a short get-together tomorrow with a mentor from the entrepreneurial center at school.
4. Writing. Wow, this is where I really need to get motivated. I have a ton of story ideas, but I haven't been very good at sitting down and pounding them out.
5. Apartment hunting. This is low on the priority list, but still at the back of my mind. We have a place, but we'd like a better place. It'll just depend on how much time/motivation Child and I can scrape together.
6. Planning fun stuff. I want to get together a couple friends and do some snow-caving.
