Fireplace progress...

Fireplace progress...  The masons were here all day today putting in the hearth for the fireplace.  First there was a layer of brick support, then a thin strip of stone across the face, and finally the “floor” part of the hearth.  That last bit included a lot more puzzle-piece solving than the facade did, mainly because the pieces of hearth stone were more angular, and varied more in size.

As yesterday, these photos are in time order.  The last one shows the completed stonework.  All that remains is cleanup and sealing, which will happen Monday afternoon...

How aerodynamic lift actually works in a wing...  The clearest non-technical, no-math explanation I've ever seen for this phenomenon.  Most people who believe how airplane wings work actually don't – not because they're dummies, but because nearly every textbook and teacher has taught them a fiction.  Usually it's something like what's at right...

Corruption, American-style...

Corruption, American-style...  Here's a great example of the sort of corruption that pervades American politics.  We don't suffer from the kinds of corruption that are rampant in Russia, India, China, and the Middle East – but we have it nonetheless.  There are many examples besides car dealers – cable companies, many professions that require licenses, etc.  All of these have common characteristics: they protect the incumbents at the expense of consumers.  All also assiduously avoid the sunlight: they don't want consumers to understand how they're being bilked – because, naturally, that would end the happy days of free money for them.

Tesla is doing a public service by exposing the corrupt crony capitalism in the states where its running into this sort of thing.  It's not motivated by altruism on their part, of course, but it's a public service nonetheless...

Barn progress: house wrap...

Barn progress: house wrap...  Not much happening today, but the builders did come by to install the “house wrap” that weatherproofs the barn.  Hopefully they'll be installing windows and doors tomorrow...

The masons' dogs...

The masons' dogs...  Each of the masons has two dogs, and they bring the dogs with them on their jobs.  That means for the past couple of days I've had the pleasure of having four well-loved, happy, playful dogs running around my yard.  I miss my dogs terribly (they're still in Jamul with Debbie, though hopefully not for long!), so this unexpected “dog infusion” was a pure delight for me.  Here's some photos of these guys:


Fireplace progress...

Fireplace progress...  The masons got the entire facade in place today.  The striking will be done later this afternoon, after the mortar sets up a bit.  I watched them for a couple of hours as the put the last pieces in place – finding rocks to fit the last holes was quite a laborious process, and involved a bit of grinding to knock the edges off some of them.  It was a pleasure to watch these two work together.  Despite the difference in age (24 and 63), they worked together like a team that had spent their whole life together.

Randy B. (the older fellow) and I are traveling to Tremonton this evening.  We're visiting a rock vendor there, hoping to find us some good hearth stone.  The original selection we made is out of stock now.  Assuming we succeed, tomorrow the hearth will go on.

Once the mortar everywhere has had a chance to cure, they'll be finishing up with an acid wash (to remove mortar streaks) and a plain water rinse.  Once that dries, they'll be applying a coat of satin finish sealer, which will make the rocks look like they're damp – and that makes the colors “pop”.

The photos below are in time order, which makes it easy to see the progress they made during the day.  The last photo shows all the leftover rock we have – roughly 35 square feet worth.  They need this extra in order to be assured that they can find rocks of the right size and shape as they go.  It's really beautiful rock, so we're going to have to find a use for all that :)

What Obama policies would Mark Udall oppose?  Why, he can't think of any!

Of course he can't.

I freely admit to a satisfying sense of schadenfreude when I watch the Democrats running in 2016 trying to pry themselves away from any association with Obama.  “Toxic” is the word they're using for Obama.  It's a damned shame we have to endure him for eight years before the ignorant, fact-avoiding electorate figures that out...

“This makes Parisians' treatment of American tourists look good in comparison.”

“This makes Parisians' treatment of American tourists look good in comparison.”  Researchers recently posed a (supposed) moral dilemma to a number of people and measured the results.  They posed a situation in which the participant had to choose between saving the life of their own dog versus the life of a person.  They varied the degree of attachment between the participant and the person, from sibling to foreign tourist.  When they tested their own dog versus the foreign tourist, about 40% of the participants chose to save their dog.

My reaction: what the hell is wrong with the other 60%!  This seems like an easy choice to me: my dogs are far more important to me than the vast majority of humanity.  Far more worthy, in most respects, too.  The moral choice is to save my dog!

The general reaction: what the hell is wrong with that 40%!  I find this utterly appalling.  They'd let their dog, whom they love, die to save some random person with whom they have no connection?  That seems highly immoral to me.

Fireplace progress...

Fireplace progress...  I spent much of the day working with the two masons as they got started on our new fireplace.  The first thing they did was to clean out all the poorly-done elements of the old fireplace, and there were several of them.  Then we had to re-mount the mantle because the mounting plate I used was the thickness of “normal” thin veneer rock, and the rock I actually bought was much thinner.  We finished up that stuff by about 2 pm, then the masons mounted their tarpaper underlayment and armature wire to the wall. 

At that point they were ready to actually put up some rock, and they did – as you can see in the photos, the bottom two rows of rock are up.  It was fascinating to watch the masons work – the things they do range from the violent and coarse (like removing old blocks and mortar) to the delicate and fine (like the final step of brushing the mortar between the stones).  Some of what they do requires great skill and artistry, such as choosing rocks of the right shape and orientation to artfully fit with what's already up, and the fine work of “striking” – getting the mortar between the stones to look attractive.  They use a narrow, long trowel to do most of the striking, but finish it up with bare fingers and a light brushing at the end.  Like so many other things, masonry work requires more skill and experience than you might think...


“That’s a lot of nonsense to pack into one paragraph.”

“That’s a lot of nonsense to pack into one paragraph.”  I read Foer's piece on the need to stop Amazon, and I had several simultaneous urges: to beat my head against a concrete wall, to smack him upside the head with a nice hard object (a sledge hammer would do nicely), and to write a rebuttal of it.  The latter seemed a bit overwhelming, as there was so much that needed rebutting.  But now I see that David Post has saved me the work, by doing a fine job himself.  The leading quote is from his piece...

The new fireplace is underway...

The new fireplace is underway...  On Monday a truck pulled up with the thin veneer river rock I'd ordered from Portland, Oregon.  It was a week late, but the product was beautiful.  Yesterday the mason who's building my fireplace started the work.

The first step was to clean the incredibly dusty pieces of rock.  They were dusty from the sawing operation, which uses saw blades with very fine pieces of diamond in them.  The “rock dust” that results is incredibly fine – it makes talcum powder feel coarse.  This dust had penetrated every tiny little nook and cranny in the surface of the rock.  The masons first washed all the rocks with a 3,200 PSI pressure washer.  Then they scrubbed them with dilute acid, and pressure washed them one more time.  The result was almost miraculously different than what they started with (see first photo below).

Then they brought all the stone inside and laid it out on our living room floor (see second photo below).  This is so they have a “palette” of stone to choose from as they build the fireplace.

Then they tackled the wall.  The big job here was to clean off the remnants of the three separate iterations of fireplace that were here before.  It started off in 1992 as a brick fireplace, then became a manufactured stone facade fireplace, and then a slate facade fireplace.  We're replacing the slate version with this river rock.


“...like a conservative’s hallucinogenic fever-dream of cultural life in Manhattan.”

“...like a conservative’s hallucinogenic fever-dream of cultural life in Manhattan.”  That's a line from one of the funniest things I've read in a long time – and it's a review of a production (by Kevin D. Williamson) of Shakespeare's The Winter's Tale.  How I, of all people, came to be reading that is a funny story itself, which I'll likely tell some other time.  I'm glad I did, though, because otherwise I'd have missed this:
Which brings us, strangely enough, to the recent performance of The Winter’s Tale, or something purporting to be The Winter’s Tale, staged by Public Works, a sub-fiefdom of the Public Theater’s inexplicably beloved annual outdoor program at the Delacorte Theater in Central Park. Far from speaking truth to power, the Public Theater has demurely presented power with its hindquarters like a rutting and not particularly choosy she-baboon. To endure it is to take a guided tour of everything that is low-minded, banal, cowardly, and loathsome about American theater.

To say that The Winter’s Tale is the worst thing I ever have seen staged would be an understatement. It represents nothing less than the complete abandonment of artistic and intellectual standards—to say nothing of self-respect—and what may as well be the last word in the degradation of theater and its reduction into a branch of politics. Every professional involved with this supine display of sycophancy should, after a thorough examination of conscience, go into retirement, or else be forcibly driven to it. No reputation should survive.
To think that I thought that the artful insult was dead!  There's more, much more, including the use of the unlikely phrase “Muppet kung-fu stilt-band circus”.  Read the whole thing.

Schrodinbug...

Schrodinbug...  That's a new word for me, learned when I read this article.  I've run across a few schrodinbugs myself over the years, far too often for their existence to be merely chance or coincidence.  In at least a couple of cases, I was able to track down the authors (there always seem to be two :) – and I discovered that one bug predated the other, and the later bug was deliberately created to compensate for the first bug.  There are lots of scenarios where the foibles of the ordinary humans who write software would cause this.  For instance, suppose a very senior, well-respected engineer accidentally created a bug like the one described in the article.  Then one could imagine a very junior, timid engineer trying to use that code, running into the bug, and then either assuming that the first guy must be right, or simply being afraid to approach that first engineer.  The natural result of that would be to write the compensating “counter-bug” to get the correct result despite having two bugs.  In one of the cases where I talked with the authors, I'm pretty sure that's exactly what happened.

Something I've seen much more often than straightforward, provable code schrodinbugs are what I'll call “architecture schrodinbugs”.  For example, suppose an engineer implements a working, but poorly designed API (this is so common one could consider it to be the norm!).  After that, there may be many programmers who write contorted code that uses that API – in effect, every one of them is a counter-bug, and the pair of the crappy API and the resulting twisted client is an architectural schrodinbug.  They're also how most software is built :)

Big data you can use...

Big data you can use...  I just ran across the web site CamelCamelCamel for the first time.  After just a few minutes perusing its features, I can tell I'm going to be using it often.

CamelCamelCamel does something that sounds simple enough: for any product on Amazon, it tells you the price history – and will send you alerts when the price of a product you're interested in drops below a value you set.  To do this, CamelCamelCamel had to collect a lot of data.  The products that I looked at this morning had price history going back as much as several years, as well as comparisons to third-party (e.g., not Amazon) vendors.  I'm kind of fanatical about getting the products I want at the best price I can while still getting acceptable levels of customer service.  CamelCamelCamel looks like a huge time saver for me when I'm considering products whose prices I'm not that familiar with...
