Possum pictures

Filed under: Personal,Wildlife Rehab — cec @ 10:48 pm

Back in August I wrote about a rehab possum that K was taking care of – she was very much a cutie.  I was looking through some pictures on the camera and realized that I had a few more of her.  Now that she’s all grown up and has been released, I thought folks might like to see them:

Here she was back in August:

A month later, in September:

And then after she had been outside and right before release in December:

  

The last two were from the night we started leaving the outdoor cage open so that she could leave when she wanted to.  It took her a bit before she left.  Hopefully she’s doing well.

Work blogging

Filed under: Personal,Technical — cec @ 10:37 pm

Last week at work was pretty interesting. On Tuesday, L and I flew up to Dayton for the day to meet with our sponsors. That meant a 6am flight out and originally a 11pm return flight. Fortunately, we wrapped it up a bit early and landed home back around 8:30pm. The meeting went well. We were presenting some ideas that I had to the sponsors and they seemed to like them. Strangely enough, in talking to L, he said that he hadn’t really understood what I was proposing until the meeting. Not bad for a guy who wrote a short paper for the sponsors that described what he didn’t understand! But then, I guess that’s why L’s a full professor 🙂

Wednesday was largely recovery. Thursday, I met with the other modeling guy on the team who was in from New York. We discussed what I wanted to do and he seemed to have a good handle on it which was good because later in the afternoon L came in and wanted to discuss it in more detail. He had been stuck in an airport and had time to think through some things. The bad news is that he didn’t think my proposed modeling would work. The good news is that he thought he had a fix.

Turned out that I had forgotten that the underlying model we are using is a Markov model. The basic requirement of the model is that the software agent can only be in one state at a time. I was essentially proposing that the agent could be in multiple states simultaneously. As we talked more, I realized that L’s proposal was to generalize what I was getting at. Essentially, I described the special case of m=1. Before my proposal, we had been working with m=n. L’s proposal was to let m vary between 1 and n. This bugged me at first since I thought m>1 wasn’t necessary. I was also concerned since L and the other modeler, N, had theoretical objections to m=1. I pointed out that really for any m<n, their theoretical objections held true, so nothing was really more wrong with m=1. Everyone agreed with that and we further agreed that a varying m would still have some theoretical problems, but would be more effective, more realistic and more tractable than m=n or m=1.

Wrapping that up, I received a short email from L on Friday thanking me for the work, saying that was a good white board session and that he could see how my thinking was influencing his for the better. That was nice 🙂

p.s. if y’all are really nice, I promise not to write a blog post on Markov decision processes

K wins!

Filed under: Personal,Social — cec @ 9:56 pm

Okay, slight confession time.  I’m something of a closet political junkie.  Not so much the “who’s up, who’s down” campaigning politics, but the questions of policy, who supports what, what makes sense kind of thing.  If I were involved in politics directly, I suppose that would make me a wonk, not a hack.

Anyway, K and I were having a discussion last week about the presidential primaries.  K’s position was that if Huckabee wins the GOP primaries, we’re all in serious danger because the man holds positions that are bad for women, minorities, basically everyone that’s not a middle class white heterosexual male.  I, on the other hand, maintained the position that a Huckabee win in the primaries would be hysterical.  🙂

To a large extent, our positions were based on different contexts.  K is concerned that the republican would win the general election since, hey, it’s been a while since they haven’t – no matter how bad their candidates and policies are.  I was thinking “hysterical” since it would break wide open the GOP coalition of money, guns and religio and I have a hard time picturing any republican winning this time, since they are all so awful.

So, that said, I think K wins this one based on this short article:

“[Some of my opponents] do not want to change the Constitution, but I believe it’s a lot easier to change the constitution than it would be to change the word of the living God, and that’s what we need to do is to amend the Constitution so it’s in God’s standards rather than try to change God’s standards,” Huckabee said, referring to the need for a constitutional human life amendment and an amendment defining marriage as between a man and a woman

I’m more than a little terrified that a presidential candidate would talk about amending the Constitution in order to suite his own religious beliefs.  Where do you even start with this?  This country was established to intentionally and explicitly keep religion from controlling the government.  While the phrase “separation of church and state” is not in the constitution, the concept is one of the founding principles of the constitution as a whole and of the first amendment in particular.  The founders saw first hand the damage that could be done when a particular religion dictated to the government.  This is why the establishment of religion was explicitly forbidden.

Beyond the 200+ years of tradition, beyond the very heart of our government, there’s the whole other issue of which “word of the living God” to you plan to establish? There are over a dozen major religions represented in this country.  Even within the largest, there are literally hundreds of Christian denominations (side note, why are splits among Christian beliefs called denominations and those of non-Christian beliefs called sects?) each of which has there own special interpretation of the god’s word.

Perhaps Huckabee was just pandering to republican christians, many of whom can be counted on to support certain positions.  But to make the claim that these republicans speak for all christians, let alone for god or all religions is crazy.

So, yes – K wins: Huckabee winning the GOP primary would not be hysterical, it would in fact be scary.

Is this thing on?

Filed under: Guitar,Personal,Security — cec @ 9:25 pm

<thump> <thump> Is this thing still on?

Okay, it’s been about three weeks since I’ve blogged anything.  As I’ve stated before, this tends to happen when I’m too involved in living life to actually write about it.  Fortunately (unfortunately?) it’s nothing terribly exciting.  Let’s see:

  • Guitar: my guitar playing has been scientifically shown to have 10% less suck than it did a month ago.  However, with such a large amount of suck to begin with, we’re still not at anything that looks like good.  I’m getting more fluent with the open chords and can switch between them reasonably well.  I’m just starting to learn barre chords – the E barre chord to start with.  There are still vast tracts of untouched suck in the barre chords.  Also, I’m actually thinking of picking up some lessons – the ones at jamplay.com seem pretty good.
  • Work:  still going well.  There’s enough to do.  I’m still not entirely used to billing by the (tenth of an) hour.  Also, not really looking forward to flying to Ohio next week.  I’ll only be gone for a day, but, ugh – who wants a 6am flight to Dayton!
  • Break-in update:  nothing much new here.  Still looking to make it harder for someone to break in.   Had a neighborhood watch meeting last weekend – that’ll be good.  Turns out this may be neither contractors nor kids.  There are apparently some professional (stretching that word a bit) thieves working this area.  There have been some eight different break-ins near by.
  • Non-profit work: I’m convinced that whomever coined the phrase “academic politics are so sorted because the stakes are so small” never worked with a non-profit.  It’s just amazing the degree to which politics enters into the smallest damned thing.
  • New year’s resolutions: didn’t make any – never do.  That said, I am trying to exercise more and cut down on my use of vulgarities.  Profanity and cursing can wait until another year 🙂

I think that’s about it for now.

Chop wood, haul water

Filed under: Personal — cec @ 10:04 pm

“Before enlightenment, chop wood, haul water.  After enlightenment, chop wood, haul water,” is one of my favorite zen aphorisms.  Okay, so no hauling water for me – at least not unless the drought gets worse, but there’s going to be a lot of wood chopping in my future.

On Saturday, margaretc’s husband, ‘A’, came by and took out two of the trees that have been worrying me.  They border our drivway and both had holes in their bases.  Since they’re not small trees (40-50+ feet tall), I was worried that they would either come down on the house, the 500 gallon propane tank, the cars, the well, the power lines – you get the idea.  It seemed better to take them out on our own terms.

The removal went well.  It’s a great comfort to have a certified master arborist doing the work 🙂 .  ‘A’ climbed the trees – rope climbing the one and spiking the other (impressive!) and sat up top cutting the major limbs.  After that was done, he rigged a multi-pulley system so that we could pull the trunks down to a location that wouldn’t  cause any harm.  It went perfectly.

Now I have to finish cutting up the two trees and chopping the rounds into firewood.  Looks like we won’t need to buy wood for a year or two.  Surprisingly, chopping wood isn’t as bad as I thought it would be.  I need to work on my technique, but it could wind up being fairly enjoyable.

Next tree project – order and plant some replacement trees.  I’m thinking a couple of walnuts might be nice.

Information markets

Filed under: Technical — cec @ 5:32 pm

One of my projects at work involves information markets: tools to extract aggregate knowledge from groups of people.  For example, at Intrade, you can buy and sell contracts on questions like, “who will be the democratic nominee for president?” or “how likely is it that the US economy will slip into recession?”  The market price reflects the cumulative belief that a given event has a certain probability.

IEEE Spectrum also recently did a piece on information markets which talked about Microsoft’s use of a market in 2004 to predict the likelihood of an internal product meeting its production schedule.  By opening the market to its employees, who presumably had knowledge of the issues with the product, Microsoft predicted that it would ship three months late – which it did.

All of that got me to thinking about how much fun (and subversive 😉 ) an employee operated information market would be.  The questions are great: “how likely is it that we’ll be re-organized my March?”  “will the next good job go to the boss’s friend, neighbor or gardener?”  “which product will be selected in the next RFP?”  “how likely is this project to fail (or succeed)?”

If anyone wants to set up something like that, I’ve got some code, or you can use Zocalo.

Break-in Update

Filed under: Personal — cec @ 4:43 pm

It’s been about a week and a half since the attempted break-in.

On Tuesday, I replaced the window they broke out.  I called around to a couple of different places and everyone said that they could send someone out to give an estimate, but it would take a few days and then the part would be on order for another 3-5 days.  Fortunately, on local glass shop said that if I brought them the sill in the morning, they would be able to replace the glass that afternoon.  So I spent the morning taking apart the window.  It turned out to be easier than I thought, but I did have to take off the lower sill to get to the upper.

I got the sill to the glass shop and they managed to replace the glass by the 5:15.  I brought it hope and replaced the window in just a half hour or so.  Yay!

Today I found out that the same morning someone was broken into down the street on the same day as our attempted break-in and in the same way.  For a variety of reasons, they suspect contractors at the two construction sites in the neighborhood.  They’re chasing down the details of who was on site, etc.  Hopefully they can track down enough information to identify the burglars.

New faucet

Filed under: Plumbing — cec @ 6:11 pm

I picked up a new kitchen faucet at Lowe’s today.  As usual with this sort of thing, removing the old faucet was the worst part.  The nuts holding the old faucet on to the sink were standard plastic nuts – attached to badly rusted screws.  After 30 minutes of trying: first by hand, then with a towel by hand, then with a wrench, then oiling the screw and trying the wrench, I gave up.  Thinking about it for a few minutes I realized that I have a 1″ drill bit for putting holes into a sink.  I got the drill and just drilled through the plastic nuts.  Victory!

Of course, in taking off the old faucet, I put a little pressure on the spigot and it completely broke off.  I’m just glad it held off until now 🙂

Once the old faucet was out, installing the new one was pretty easy.  I had remembered to buy new faucet connection lines which was good since I needed ’em.  I also remembered to pick up some more teflon tape which was helpful.  The only real mistake I made was testing the cold water tap after connecting it.  Unfortunately, the hot water tape was open so all of the water headed that way and down under the sink.  But at least I wasn’t under it. 🙂

Hopefully we’ll be set now.

Attempted break-in

Filed under: Personal — cec @ 10:00 pm

Some weeks it just doesn’t pay to leave the house. As K and I were getting ready for bed last night she noticed that the bathroom window was broken. Being a wildlife rehabilitator, her first thought was that some bird (maybe a hawk) had smashed into the window. I went out to check. Nope – someone had removed the screen and smashed the window with some junk they found on the deck.

It seems they broke the window in order to unlock it and sneak in to the house that way. Fortunately, they didn’t succeed. In breaking the window, they knocked the window lock latch off and couldn’t unlock the window. They tried prying it up (first?) but failed there too. I’m guessing between the frustration and the dogs barking like mad, they gave up.

We called the cops and filed a report.

What I don’t understand is why the window. Sure, the doors have alarm company stickers on them since the house has an alarm system, but why would they assume the window wasn’t alarmed? If they had managed to open the window, it would have set off the alarm.

This is the second break-in or attempt in my neighborhood recently. With the number of gun owners out here, if the person(s?) keep it up, they’re going to wind up shot.

While I’m happy they didn’t get in, I’m still pretty annoyed and upset by the whole thing.

Time for a new kitchen faucet

Filed under: Plumbing — cec @ 8:28 pm

It’s been 7 months since we’ve done plumbing renovations, so we’re apparently due.  This time I have to replace the kitchen faucet.  It’s started leaking badly.  “But wait,” you say, “a leaking faucet doesn’t require replacement, you can just replace the gaskets.”  Unfortunately no.

I’ve mentioned before that our water is acidic with a pH of about 5.5.   We’ve got the acid neutralizer in place, but many things have corroded over the years.  In the case of this faucet, the weld/join between the base of the faucet and the spigot itself has developed pinhole leaks.  You turn on the faucet and you get shot in the eye with water.  🙁

I’m just hoping it can wait until Saturday.
