Continuous improvement

Well, the Great Bricklaying Experiment continues. Yesterday’s work was mostly rained out. We completed most of the other projects, including bricking out a new bed under the cherry tree where the grass has stopped growing and getting landscaping ties in the front of the bed by the street. We did run into a few snags, though. There’s about a two foot gap at the end of the last tie that we’d like to fill with part of another tie, and a six-foot length along the bottom of the driveway that would happily accept the remnants of an eight-foot landscape tie with two feet cut off. The catch is that I don’t have a saw that’s powerful or long enough to cut landscape ties. Maybe my neighbor’s table saw?

Anyway, I think I’ll have to continue to lay bricks between now and kingdom come. Pictures as there is something photo-worthy.

Early delivery

A slightly sleepless night later (note to self: hamburger perhaps not the best thing to eat on a slightly acid stomach, even if homemade) and we awaken to the phone ringing downstairs. Lisa says, “I’d better turn on the upstairs ringer; we don’t want to miss the delivery call.” Then I hear a rumble from outside the window. I peek out and there’s a flatbed trailer parked across the street, with a pallet of bricks and landscaping ties atop it. I scramble into clothes and across the street and guide the forklift until he manages to push the pallet into the left stall of our garage (Lisa having volunteered to put her car outside until we can get the stuff all in place).

Yes, it’s a holiday here at Jarrett House North. The plan was to take off a day to get everything in place for our new bricked walks and garden beds. And of course it’s raining. Ah well.

Now I know…

…why Ignatz Mouse always stole his bricks, or bought them on credit, from Kolin Kelly the brickmaker in Krazy Kat. The damned things are pricey. They would have been pricier, except we found that “patio bricks” (in the building materials section, not the garden section) were more than ten cents a brick cheaper.

The bricks, as well as some landscape ties (why do they come in eight-foot lengths? That’s two feet longer than can fit in my car even with the back seat down), will be delivered tomorrow. So that left us with a light day, right? Heh. After four hours digging up the front beds, weeding, planting new plants, trimming the sidewalk, putting weedblocking cloth down, and digging the outline of a new bed in the side yard, I think that’s all the “light day” I can take.

(Incidentally, I almost wrote “Colin Creevey” in the first paragraph. Which leads to the amusing mental picture of Ignatz Mouse beaning Harry Potter with a brick, while Colin madly takes pictures of a confused Krazy Kat. Crossovers are so scary.)

Everything is Broken


Bob Dylan
Oh Mercy
Sony/Columbia, 1989

Broken lines, broken strings,
Broken threads, broken springs,
Broken idols, broken heads,
People sleeping in broken beds.
Ain’t no use jiving
Ain’t no use joking
Everything is broken.

Broken bottles, broken plates,
Broken switches, broken gates,
Broken dishes, broken parts,
Streets are filled with broken hearts.
Broken words never meant to be spoken,
Everything is broken.

Seem like every time you stop and turn around
Something else just hit the ground

Broken cutters, broken saws,
Broken buckles, broken laws,
Broken bodies, broken bones,
Broken voices on broken phones.
Take a deep breath, feel like you’re chokin’,
Everything is broken.

Every time you leave and go off someplace
Things fall to pieces in my face

Broken hands on broken ploughs,
Broken treaties, broken vows,
Broken pipes, broken tools,
People bending broken rules.
Hound dog howling, bull frog croaking,
Everything is broken.

Lincoln returns to Richmond

New York Times: In Richmond, Lincoln Statue is Greeted by Protests. I love and hate this about Virginia, my home state: the places where history happened have a tendency to become trapped in pivotal moments and hold onto them for identity long after all the original participants have crumbled to dust. A prime example: Bragdon Bowling, Virginia “division commander” of the Sons of the Confederate Veterans:

“They have no concept of history and how it might be the wrong place to put the statue,” said Mr. Bowling, whose great-grandfather John Stephen Cannon fought for the Confederacy. “As a Southerner, I’m offended. You wouldn’t put a statue of Winston Churchill in downtown Berlin, would you? What’s next, a statue of Sherman in Atlanta?”

I think Mr. Bowling is perhaps not the right person to criticize someone else’s grasp of history.

Looking to the weekend

Bright and sunny here this morning. I know it won’t last but I’m enjoying it now. Tomorrow we’ll start our first major outdoor projects, replacing some of the old bare muddy bark paths in the garden with brick and laying a new bed under the cherry tree, where all the grass is being replaced by weeds. Today, though, I have a monster of a cold. Vitamin C and eight hours in front of a computer should help.

I didn’t know you could do that with a floppy…

In the Stupid Geek Tricks department, USB Floppy Disk Striped RAID Under Mac OS X. His five floppies RAIDed together have a combined size of 4.22 MB (!) and seem to work faster together than a single floppy would separately: “I was able to transfer ‘DEVO Uncontrolable Urge.mp3’ which is 3.6 MB in 32 seconds. Which is pretty good I think.”

(Now I’ve done it. I’m going to get a lot of traffic from Google of people looking for mp3, devo mp3 (maybe not), and Wil Wheaton naked mp3 (shudder).)

Anyway, this guy has also RAIDed five Sony Memory Sticks together… I think he needs help.

Dave: Everyone’s a newbie in Boston now

Dave points out that the northbound lane of the I-93 tunnel and the Leonard Zakim Bunker Hill Bridge have opened in downtown Boston. Wow: the prospect of half the noise near the north end being moved underground is just incredible. (I’d normally get this sort of update from George, but he’s still in California. Oops. I almost said “out in California,” as though it were so far away from me now.)

MSDN comes to the party

Tim Ewald: “RSS at MSDN!” New RSS feeds for MSDN, including a comprehensive all-new-articles feed and separate feeds for Visual Basic, C#, C++, the overall Visual Studio product, the .NET Framework, and XML Web Services. There’s a lot of content in MSDN (even if most of it is by definition Microsoft-centric), and having an RSS feed through which to consume it makes it immeasurably easier to consume, navigate—and blog about, natch. Dave thinks so too.

Finally, a decent technical critique of TIA

DM Review: “TIAin’t.” Herb Edelstein points out four major problems with the TIA strategy from a technical point of view:

  • Data integration and data quality: How much time and money will the TIA folks spend just on trying to match disparate records from fifty state drivers’ license bureaus, hundreds of utility bill providers and credit application sources, and all the different banks, credit card providers, and so forth?
  • Too much data, too few examples: With only a handful of domestic terrorists and a US adult population of about 220 million, Edelstein points out, there’s way too low a signal to noise ratio: “Let’s assume there are 1,000 active terrorists in the U.S. (a number that likely overstates the case by an order of magnitude) out of a population (age 16 and up) of approximately 220 million. An algorithm could be 99.999995 percent accurate by saying no one is a terrorist. Even were we to look only at non-citizens (an arguable tactic), we would still have an accuracy rate of 99.99995 percent by declaring no one a terrorist.”
  • Lack of sufficient examples to create good signatures (identifying patterns). This is a technical refinement of the previous point, but basically the sample size of terrorists is so small that it’s hard to build patterns from them that can reliably be used to predict future terrorist activity. Further, Edelstein points out, terrorists exhibit adaptive behavior, learning from what gets other terrorists caught.
  • False positives. Edelstein summarizes this point as a kind of Hobson’s choice: you don’t want to falsely accuse anyone but you don’t want to miss any terrorists. And if you have a failure rate of your algorithms of 0.1%—an overwhelming success in most data mining applications—that’s still over 220,000 potential false positives!

Edelstein concludes that the right answer is to improve the technology and use it to answer fixed questions rather than look for patterns in all possible available data—to use the system for decision support rather than rely on it to make the decisions.

My question: given the large amount of money to be spent, and the large likely consequences of arresting and incarcerating innocent people, how big a disaster do we have to be able to predict and eliminate before a system like this justifies its cost?

These are the things about my neighborhood

  1. No matter how wet and nasty the previous night was, I’ve been waking up each morning to sunlight and a world washed clean. There’s a bit of a wet green glow everywhere I drive. (Never mind that much of it might be dandelions.)
  2. I discovered the world’s scariest parking lot in downtown Kirkland last night: not in terms of violence but just in terms of gravity. The lot is on a steep (about 40°) hill, and rather than have the cars park with noses facing toward the bottom of the hill, they have the spaces along the contour of the hill, so that the parked cars have their drivers side about two feet lower than the passenger side. I swear, I was afraid the car was going to tip over on me as I got out. Pictures soon.
