Dog Found!

Update and bump:

I received this email note from the fellow who found the dog:

HI TOM. THANKS FOR YOUR EFFORTS. I POSTED SIGNS AND HAD TWO RESPONSES, BUT THE DOG WASN'T THE ONE. ANYWAY THE DAY BEFORE YESTERDAY, AFTER THE DOG ATE IT VANISHED AGAIN. I BELIEVE IT IS OUT LOOKING FOR ITS OWNER ITSELF. NICE OLD DOG, BUT OBVIOUSLY SAD AND NOT INTERESTED IN HANGING AROUND. IT WAS NOT THE FIRST ONE THAT TURNED UP HERE. I THINK THE BARK IT OUT THAT WE FEED GOOD. ANYWAY, SO FAR WE HAVE RETURNED 6 OR MORE DOGS TO THEIR OWNERS WITH A WORD OF ADVICE. "IF YOU WANT THE DOG TAKE CARE OF IT, ITS PART OF YOUR FAMILY NOW"

Yes, indeed, folks – our four-footed friends are very dependent on us despite their wild ancestors. My wife and I are saddened all too often by the loss of a neighbor's dog or cat to a genuinely wild predator, or a car. We are very careful with our own “family” of three dogs and eight cats – the dogs are outdoors in our fenced yard only when supervised, and our cats are either strictly indoors or are outside in a cattery that is predator-proof. We're especially careful when there are thunderstorms, as one of our dogs (Lea) is terrified by the sound and completely loses her mind. If we let her out in the yard when there was thunder, it's easy to imagine her running away in sheer terror, with no idea where she was going and paying no heed to cars, bobcats, rattlesnakes, or mountain lions along the way…

I received this email concerning a dog found near the Lyons Valley Trading Post:

FOUND LARGE, OLDER BROWN RETRIEVER. SCARED OF LIGHTNING. LYONS CREEK ROAD, NEXT TO TRADING POST. 468-3853. POSTED SIGNS. THANKS.

I'm trying to find out more, but that's all I know at the moment.

If that dog is anything at all like Lea (our female field spaniel who is terrified of lightning), then it sure will be glad to see its owners again...

Just received this as a comment:

Lost Yellow Lab, Friendly 11 year old missing since Sunday morning if found please contact the number on her tags OR call 916-7521 OR 994-1609

Ahhh....

Last night, for the first time in nearly a week, we opened our windows to the lovely, cool, crisp air of an evening in the desert. Along with the cool air came the perfume and sounds of the chaparral.

We've been having a bit of a heat wave the past week, with temperatures reaching 110F (43C) – though thankfully that extreme was very brief! We had several hours on several afternoons of temperatures over 100F (38C), with very low humidity – but still, all we could do was hide in the house with the air conditioner. But the worst were the hot nights – two nights with the temperature running almost 85F (30C) all night long – so we kept the air conditioner running all night long.

Until last night. The heat wave broke very abruptly around 3pm yesterday afternoon, and last night was very pleasantly cool. As I write this, it is almost 9 am and it is still very pleasant outside.

Ahhhhh…

Rain!

Rain. Yesterday afternoon, it rained. A glorious, if brief, downpour dropped 0.16" (about 4mm) of water on our parched patch of desert. Oh, it was wonderful! Big, fat raindrops splatting all around us. The ground actually got wet. The dust sloughed off the chaparral's leaves. The air filled with the delicious aroma of wet earth. The temperature dropped by 10 or 15 degrees (F) in just a few minutes. A rainbow crossed Lawson Valley. And the fuel moisture shot up to over 20% – so, if only for a few days, our fire danger is greatly reduced.

There's a 20% chance of rain each day and night through Monday. We're hoping for more!

Fortress Update

Well, my highly unreliable contractor (Ruben Ponce) has done it again.

Earlier this week, through my own personal inspection and the help of a very experienced friend (Dick F.), I determined that the work done on the form and reinforcing steel for the roof was unacceptable. There were many problems. My contractor came out to my site, reviewed the list of discrepancies with me, and agreed to fix them – before the inspection scheduled for Wednesday.

Naturally, he never showed up on Monday afternoon, Tuesday, or Wednesday. But he did call me on Thursday morning to tell me that he had rescheduled the inspection for that same day (which was yesterday), and he was convinced that the work would pass inspection without any additional changes. He then said he'd still make the changes I'd requested, but I suspect that once the inspection was passed, he'd put all his efforts into convincing me to pour the roof as is.

Well, the inspector showed up yesterday, as scheduled. He did not approve the job. He found six specific discrepancies (five of which corresponded to one of the eight that I found, and one of which was a new one) that will have to be fixed before he will approve it. He also made quite a few additional criticisms of the job; things he said he'd still approve anyway, as they didn't violate any building code or regulation – but things that he would never allow on any job he was in charge of.

Sigh. So now I know that my own intuitions, and the judgment of my experienced friend, were closer to the mark than my contractor. And I still haven't been able to get my contractor out here.

Some assembly required…

If Your Wallet is Stolen…

One of my loyal readers (Chrys) passes along this email she received. I can't personally vouch for the contents (other than the phone numbers given, which do check out), but it all seems quite sensible to me:

A corporate attorney sent the following out to the employees in his company.

1. The next time you order checks have only your initials (instead of first name) and last name put on them. If someone takes your checkbook, they will not know if you sign your checks with just your initials or your first name, but your bank will know how you sign your checks.

2. Do not sign the back of your credit cards. Instead, put "PHOTO ID REQUIRED."

3. When you are writing checks to pay on your credit card accounts, DO NOT put the complete account number on the "For" line. Instead, just put the last four numbers. The credit card company knows the rest of the number, and anyone who might be handling your check as it passes through all the check-processing channels will not have access to it.

4. Put your work phone # on your checks instead of your home phone.
If you have a PO Box, use that instead of your home address. If you do not have a PO Box, use your work address. Never have your SS# printed on your checks, (DUH!). You can add it if it is necessary. However, if you have it printed, anyone can get it.

5. Place the contents of your wallet on a photocopy machine. Do both sides of each license, credit card, etc. You will know what you had in your wallet and all of the account numbers and phone numbers to call and cancel. Keep the photocopy in a safe place. Also carry a photocopy of your passport when traveling either here or abroad. We have all heard horror stories about fraud that is committed on us in stealing a name, address, Social Security number, credit cards.

6. When you check out of a hotel that uses cards for keys (and they all seem to do that now), do not turn the "keys" in. Take them with you and destroy them. Those little cards have on them all of the information you gave the hotel, including address and credit card numbers and expiration dates. Someone with a card reader, or employee of the hotel, can access all that information with no problem whatsoever.

Unfortunately, as an attorney, I have first hand knowledge because my wallet was stolen last month. Within a week, the thieves ordered an expensive monthly cell phone package, applied for a VISA credit card, ha d a credit line approved to buy a Gateway computer and received a PIN number from DMV to change my driving record information online.

Here is some critical information to limit the damage in case this happens to you or someone you know :

1. We have been told we should cancel our credit cards immediately. The key is having the toll free numbers and your card numbers handy so you know whom to call. Keep those where you can find them.

2. File a police report immediately in the jurisdiction where your credit cards, etc., were stolen. This proves to credit providers you were diligent, and this is a first step toward an investigation (if there ever is one). However, here is what is perhaps most important of all (I never even thought to do this.)

3. Call the three national credit reporting organizations
immediately to place a fraud alert on your name and Social Security number. I had never heard of doing that until advised by a bank that called to tell me an application for credit was made over the Internet in my name. The alert means any company that checks your credit knows your information was stolen, and they have to contact you by phone to authorize new credit. By the time I was advised to do this, almost two weeks after the theft, all the damage had been done. There are records of all the credit checks initiated by the thieves' purchases, none of which I knew about before placing the alert. Since then, no additional damage has been done, and the thieves threw my wallet away this weekend (someone turned it in). It seems to have stopped them dead in their tracks.

Now, here are the numbers you always need to contact about your wallet and contents being stolen:

1. Equifax: 1-800-525-6285
2. Experian (formerly TRW): 1-888-397-3742
3. TransUnion: 1-800-680-7289
4. Social Security Administration (fraud line): 1-800-269-0271

Vote for Hillary!

From Simi L., our morning political humor:

One day, the seven dwarfs left to go work in the mine. Snow White stayed home to prepare lunch. When she arrived at the mine with the lunch, she saw that there had been a terrible cave in. Tearfully, and fearing the worst, Snow White began calling out, hoping against hope that some of the dwarves had survived. "Hello, hello," she called. "Can anyone hear me? Hello!" For quite a while, there was no answer. Losing hope, Snow White called again, "Hello. Is anyone down there?"

Just as she was about to give up all hope, there came a faint voice from deep in the mine. The voice said, "Vote for Hillary. Vote for Hillary."

Snow White, somewhat relieved screamed out, "Oh, thank God. Dopey is still alive."

The 2008 Presidential elections are absolutely rife with opportunities for humor. Perhaps this will help offset the generally pathetic field of candidates…

The Rock

My mom sent me an email full of photos of a rock in Iowa, covered with patriotic art. The email had this message:

I'm told that there is a huge rock near a gravel pit on Hwy.25 in rural Iowa. For generations, kids have painted slogans, names, and obscenities on this rock, changing its character many times.. A few months back, the rock received its latest paint job, and since then it has been left completely undisturbed. It's quite an impressive sight. Be sure to scroll down and check out the multiple photos (all angles) of the rock. I thought the flag was draped over the rock, but it's not. It's actually painted on the rock too.

Of course with emails like this, you always have to wonder if it's for real. So I went to Snopes, and they have certified it as a true story – and, as is their wont, they've collected a lot more information about it:

We can't recall an occasion since the brief lifetime of the infamous Malibu Canyon "Pink Lady" nearly four decades ago that a painted rock drew as much attention as the one pictured nearby.

The object captured in the images displayed above is a 12-foot-high, 56-ton rock which stands alongside Highway 25 in Iowa, about a mile south of the town of Greenfield exit from Interstate 80. For years it featured nothing but graffiti scrawled upon its face by a host of itinerant youngsters — until 1999, when a young man who had grown up in Greenfield was inspired by the film Saving Private Ryan to make better use of the natural canvas.

Ray "Bubba" Sorensen II, now a Des Moines resident who works as an ad/web designer, was a 19-year-old Iowa State University student who had seen the Greenfield rock many times before when, around Memorial Day in 1999, he decided to begin what has become an ongoing artistic tribute to America's veterans:

It was right around Memorial Day, and I was driving by that rock and wondered what it would be like if I actually took the time to go out there and paint it. And so I painted it with the flag-raising at Iwo Jima. I got such a huge response that I kept painting it. I've been painting it for the last five years with tributes to veterans on Memorial Day.

Each year around Memorial Day, Ray uses white paint to cover over his previous year's work, then spends one to three weeks creating new scenes on his blank canvas. The photographs shown above capture the 2003-04 version of the famous Iowa rock, which featured scenes depicting Washington's crossing of the Delaware, the Vietnam Veterans Memorial in Washington, D.C., and America's response to the September 11 terrorist attacks, interspersed with quotes from presidents Thomas Jefferson, John F. Kennedy, and George W. Bush, all capped by renderings of draped American and POW/MIA flags.

Only once in the six years he has been painting the rock has his work been defaced, Ray told an American Forces Press Service reporter: his 60th anniversary tribute to veterans of the Pearl Harbor attack painted in 2001 was vandalized a few weeks after it was completed, but the perpetrator "got a punch in the face from a Vietnam War veteran for his trouble," and his work has remained undisturbed ever since.

It turns out that Bubba – who is now a web site designer – has a nice web site of his own, showing off the paintings on the rock for each of the past eight years. Check it out!

Lyons Peak Cameras

I've mentioned in past posts that Lyons Peak (just east of the town of Jamul) has four web cameras on it. These cameras update every two minutes, and they look to the four compass cardinal points (north, east, south, and west).

While these cameras are very useful exactly as they were, I thought of some ways to make them better still. So I built a web page (link is at right as well) to implement these features: overlays pointing out prominent local features, automatic sizing of the image to your screen's size, and automatic refreshing on an interval that you can select. Enjoy!

Fortress Update

The news this morning is not so good. Together with a friend (Dick F.) who is very experienced in concrete construction, I went over the roof form and rebar very carefully, “pre-inspecting” it myself. We found eight problems, some of which are likely to cause a problem with the inspection. The rest might pass inspection, but they are problems for me – for example, the slope of the roof is lower than the plan, which will likely cause pooling.

So this morning I have a meeting with my contractor, whom I hope will be able to address my list of complaints. We'll see…

Update: met with my contractor, and I have secured his agreement to fix every item on my list. Now if he'll just do the uncharacteristic thing, and actually follow through with his promise…

Update II and bump: Well, my contractor is behaving exactly as usual – incommunicado for most of yesterday and today, promises to show up here to do the work before the inspection (which was rescheduled for tomorrow morning (Thursday), and … nothing. Nada. Zip. No contractor. No masons. No phone calls. No returned phone calls.

Sigh.

Meanwhile, Paul J. had me in stitches with this email:

Sounds like an opportunity...

You contract David directly, Dick F. oversees for one of those packs of beer that you hate, but America being America you have to consider the insurance......... . Ah- sue Contractor's insurance for the cost :-)

Better still, pay David in education credits for his kids and get a tax break? Get a TV channel to sponsor the Fortress as a reality show.......

This is getting silly, need to turn in now.

It will work out, even if you have to ask the blog readers to turn up en-masse and fix it up for the price of a BBQ. You can profile the volunteers based on their answers to your science-related weekly quizzes.

How about it, dear readers? Are you up for a BBQ?

Ponder These...

…and simultaneously ponder the future of mankind.

This Week's Puzzler

Update and bump:

Simon M. writes with a question about exactly what “thread count” actually means. There are two ways one could interpret that phrase: that in one square inch there are 200 threads (counting the threads going in both directions, so 100 in each direction), or that there are 200 threads per inch going one way (so 400 going both ways). I'm not sure what the correct use of that terminology is, but … for the purposes of my puzzler, I mean the second definition (200 going each way in a square inch, for 400 threads all together).

Original post:

Suppose you have a bed sheet that is exactly 6 feet wide and 8 feet long, with 200 thread count. If all the threads that comprise the sheet were laid end-to-end, how long would the resulting thread be (in miles)?

Cast your vote at right…

Last Week's Puzzler

To be fair, there is some legitimate debate about which tyrant was the worst of the lot. Specifically, there are some reputable historians who believe Josef Stalin was the worst of the lot, and others who believe (mainly on the basis of recently revealed evidence) that Mao Tse Tung was the one. On the basis of what I have personally read, I'd say the preponderance of the evidence would give Mao the nod.

George W. Bush (I knew someone would vote for him!) doesn't even place in the top 100 on this scale.

I expected many more people to vote for Adolf Hitler, based on his notoriety – my readers are apparently better informed than most Americans…

Fortress Update

Ready for the final inspection! The inspector is scheduled to visit on Monday morning, and with any luck at all, we'll pass the inspection and pour concrete on Monday. Woo hoo!

The photo at right was the last one I took today, after spending most of the day working with the crew. I accidentally caught a piece of wood in mid-air – someone below launched the wood up just as I snapped this. What I was really trying to capture was the two “mats” of rebar up on the roof. There's an amazing amount of structural steel up there, waiting to be covered in concrete.

Today, for some reason I never did figure out, David decided to bring most of his family along: his wife, his daughter Alicia, and three of his five boys: David Jr., Eduardo, and Alfredo. Except for Alicia, all of them worked at least part of the day, even if it was just being a gopher. They all work together very well, with the kind of teasing and ribbing you'd expect from a team very comfortable working with each other. Everybody was always willing and ready to pitch in, and everybody seems to know how to do a great many things…

Yesterday they finished putting the extra shoring on the interior part of the form. It looks very sturdy now!

A neighbor and friend, Dick F. (who has lots of concrete experience) came over to show David and the rest of the crew a better way to lift the two rebar mats up to the correct height above the bottom of the form. There was a little friction at first – I think David was probably a little put out by the idea of someone telling him what to do – but he seemed to realize quickly that he might be able to learn something useful from Dick. In the end, they supported the rebar in exactly the way Dick recommended, and it looks very good to me. There's one small area where I think the top mat is a little too close to the bottom mat, but that's easily fixed if the inspector believes its a problem.

The rest of these photos show scenes from yesterday's and today's work.

Fortress Update

This is almost getting to be routine – one day after another of great progress!

As of this morning, we are getting dangerously close to being ready for the final concrete pour. The forms are completely finished (although they're going to do some extra bracing on the interior section this morning), the bottom web of rebar is complete, and the top web of rebar is well underway. We need a few more pieces of rebar, and my contractor is supposed to bring them this morning before 11 am. Of course, he's been saying he'd bring them every single day this week, sometimes promising them on multiple occasions in a single day – but they haven't shown up yet.

In an earlier fortress update, I promised I'd share my load calculations. The interior portion of the forms (the only worrisome part) has to hold up a chunk of concrete that is 16' by 16' by 11.25" (average). This works out to 39,120 pounds – 20 tons. A total of 45 4x4s will be holding that weight up, evenly distributed between them. The loading on each 4x4 is therefore 869 lbs, and that is well within their strength limits – depending on the variety and quality of the wood, a 4x4 should be able to easily handle 4 to 10 times that loading. So no worries on that score…

It's been interesting to watch how David approaches the construction of the rebar. Basically he's building the two webs directly on top of the form, and will worry about securing them at the proper level as the very last step. By doing this, he makes it much easier to put the bars into place and secure them with twisted wire – he's free to walk all over them without having to worry about falling through. He's described how the two webs will be lifted into the proper position – that process sounds quite interesting, and I'm looking forward to seeing it happen – hopefully, later today!

If that so-and-so contractor of mine actually makes it here with the rebar…

Misty Morning...

We took our usual walk “up the hill” this morning, but the view was anything but ordinary. It was crisp – cool and humid – as the sun peeked over our local mountains, and the fresh sun lit up a layer of low clouds below us. The photos here were all taken looking roughly north, toward Cajon Mountain, Viejas Mountain, and Cuyamaca Mountain. The layer of fog visible is mainly in Lawson Valley (where we live), in its reaches that are lower in altitude than our home.

Below are three more views from our walk. The left-hand photo is a panorama stitched together from three separate photos; it really needs to be enlarged (click on it) to appreciate it.

Fortress Update

Ah, another day of great progress on our safe house! The bottom part of the form for the roof overhang has been completed, and the bottom web of rebar on the roof is a little over half done. We needed some more lumber, and my contractor delivered it this afternoon – about eight hours after it was promised, but it is here. That means that David (the mason) and his son can continue working today!

A friend and neighbor (Dick F.) visited yesterday afternoon. He happens to be a retired concrete contractor, with something like 1,000 years of experience in the trade (Dick is older than dirt). He used to run big crews who built large commercial buildings, rides at Magic Mountain, bridges, and the like. Suffice it to say that he knows his stuff when it comes to concrete. Well, he went out and inspected my safe house – and was largely satisfied with what he found. He gave me some very useful tips to help ensure the quality of the job, which I will certainly follow. But his approval of the workmanship to date is very comforting…

I learned something yesterday that completely removes the concern I expressed a couple of days ago, about the blocks on the west side being higher than the blocks on the east side. It turns out that I misunderstood David in a profound way – the blocks really are level after all. It's the form that's not level, and it is sloped in order to put a slope on the roof (to let rain water run off) while keeping the roof slab a constant thickness. That part is great, and makes perfect sense. What didn't make sense was the amount of slope: 2 inches in an (approximately) 18 foot run. This slope is actually called out on the plans as a minimum of 1/4 inch per foot of run, which works out to about 4 1/2 inches in the 18 foot run. When I pointed this out to David, there was a bit of consternation – but then he figured out that he'd simply make the slab thicker on the uphill side (by 2 1/2 inches) to adjust the slope. He believes this will cause no problem at all with the inspection.

Zaca Fire

The Zaca fire is huge, over a month old, and it's a long way (over 150 miles, up north of Santa Barbara) from our home – and yet the smoke from it was all over San Diego today. Every time we stepped outside, the smoke stung our eyes and offended our noses. This photo, taken from nearby Lyons Peak this evening at 7:12, shows how thick the smoke is here.

It's hard to imagine what it must be like just downwind from the fire…

Fortress Update

After still more trials and tribulations – all involving misdeeds or failures to act by my contractor – work on our safe-house is underway again. David (our mason) was out here with yet another of his sons (this time his oldest, also David). They worked hard all day, as always. Today they started on the “forms” – the wooden structures that will hold the liquid concrete in place when they pour the roof. Today they largely completed the part of the form that will shape the interior ceiling. Tomorrow they will put a few more supports for this in place, then construct the forms that will shape the overhang of the roof, and its edges.

The weight of the concrete roof (which I've calculated will be about 23 tons) means that the supports for the form have to be very, very strong. At the same time, though, the form is a temporary structure, and it must be easy to take apart. Those constraints make the form-work an interesting engineering challenge. One simple device David used will make the disassembly much easier – he's using special nails with two “heads” on them. One head is where it usually is, on the end of the nail opposite the pointy end. The other head is about a quarter inch from the first head, down the nail's shaft. When the nail is hammered in, it stops at this extra head – and the usual head is then exposed (with a bit of the nail's shaft), ready for easy removal with a hammer claw. A simple, but very effective, invention.

When David has finished this interior form tomorrow, I'm going to do some rough calculations just to make sure the loading on those 4x4 posts is acceptable. David seems very sure of himself, but to my eye this just doesn't look strong enough to hold up such a ginormous block of concrete. I expect my calculations will prove David right, but I will feel better if I can prove it to myself… Can you imagine the mess it would make if that form collapsed, letting 23 tons of liquid concrete slosh out? Ach, I don't even want to think about it! And even worse – what if someone was up on the roof when this happened? No, it's better in this case to be paranoid, and to triple-check every step of it...

There was one big surprise for me when I first saw the form this afternoon: the form is even with the tops of the cement blocks on the east side (at the right in both this photo and the one at the top of this post), about about 2 inches below the blocks on the west side (at the left in the photo at the top of the post). David explained that it was important for the form to be perfectly level, so that the top of the roof is also level (except for the slight drainage slope that will be built in) and the roof is of the correct thickness. Well, that makes sense. But…something else was bugging me. I knew darned well that the slab was level to within a fraction of an inch – I watched them do this, and double-check it. So why were the blocks slightly higher on one side than the other?

David was unable to explain this to me, largely, I think, because of the language barrier (his English isn't up to a sophisticated discussion, and my Spanish is non-existent if you're not talking about food). My current theory is that there was some kind of systematic error in the way David placed the string that formed his level reference as he was laying the block. I expressed some concern about how this might affect us passing the inspection (this inspection will occur just before we pour the roof). David understood that concern well, and assured me that such small errors are a commonplace occurrence in block wall construction. I sure hope he's right…
