Update

Getting the old house ready to sell has been a real problem. The yard needs a lot of clean up work to have good curb appeal and to fix all of the deferred maintenance problems like the ivy in the trees and tree limbs encroaching on the house. The carpets need to be cleaned. The whole house needs to be scrubbed top to bottom. And, worst of all, the front bedroom and the office need to be repainted. I’ve been working on the painting for a couple of days now and I am ready to be done with it. I prepped and painted all day Wednesday and then again for three hours last night. Looks like this Saturday morning will be more painting, trying to get the front room done before the carpet people come at 1:00 and get the office done in there some time too.

The garden was enough of an extra expense that I told the yard people not to do it. Mom is coming up so we’ll do painting and garden stuff and then some cleaning. The good news is that once Saturday is done the house should be almost ready for a For Sale sign. I also have two people that already live in the neighborhood that are interested in buying it and my neighbors tell me that there are a lot of investors that are looking for houses like mine too so I might get a couple of bids. I would prefer it go to a family rather than a California Rental Tycoon but it will be hard to turn down money.

Easter was last weekend and I went to Mom’s to see the family. There ended up being quite a bit more family than I expected. It was fun and I got to see my nieces. They grow up so fast. I can’t believe they’re almost three. Little people with personalities and everything. Crazy.

The ill-fated bookshelf project mk.2 has finally progressed. A local metal worker, Jeff McGlew, built the metal frames I designed and they’re perfect. The dimensions are correct, they are square, the weld finishes are very clean and they’re even pretty light weight. I’ll Scotch Brite them down and then put some paste wax on them to finish. Then I’ll need to start cutting the nice maple veneer plywood I got to make the actual shelf surfaces. I may trim down a spare piece of MDF I have just to see how it fits and looks to start with. The finishing regimen I’ve decided on will be a long, tedious and high VOC affair. A gallon of either Waterlox Original or Arm-R-Seal and four coats a side. I’ll have to figure out how to get good ventilation in the garage and to keep the TR6 from getting all solvent abused.

The big news is that I am seeing someone. I’ll refrain from putting her personal information all over my blog but she’s been a friend for a while and we started dating a little more than a month ago. I’m very happy and she seems to be happy as well. We’ve been mostly cooking dinner and watching a few TV shows as dates but we went to Cantine for dinner this week. The fried olives and the affogato were both tasty treats and we each enjoyed our pasta also. She has a cat which is less of an issue than I feared it might be and I even had the little fluff stay at my house for a day during apartment maintenance. I look forward to seeing her every time we have something scheduled and I miss her when we don’t.

Commute

I moved houses, remember? The new house is about 3.5 miles from work and there is reasonably safe road and bicycle lane the entire way so I have been commuting by bicycle. Aside from the odd weather fluctuations we have it has been a good change. I get around 40 minutes of aerobic exercise per day and though my weight has been pretty constant (I easily eat back the 300 kcal I spend exercising) the general shape of me is better.

I have been tracking my rides with my little GPS bike computer and putting them into Strava. Strava tracks “segments” which are routes with a defined start and stop and it ranks you vs. other users on the time it takes you to complete the segment. The person with the fastest time through a segment is King or Queen of the Mountain and for some segments there’s some pretty stiff competition for KOM. I have one segment that I have tried very hard on, southbound Guadalupe between 29th and 24th, and I’ve managed to get myself into a four way tie for 7th at 1:10. KOM is 1:03 which is an average speed of not quite 29mph. I also accidentally got 3rd on the segment that is 5th st. from Guadalupe to Sabine the other day but that is almost entirely due to luck with the traffic lights.

My GPS computer is kind of flaky and randomly kills its battery during the day. It also takes a long time to acquire satellites and its accuracy is not the best even when it has a lock. I would like a new one but because I have one that basically works I’ve been making myself earn it. The challenge is thus: I must commute to work a minimum of three days per week until I have commuted 30 days. At the outside that is 10 weeks but I can bring it in by riding more. I must also ride 300 miles which is $1 per mile for the specific toy I want. All rides that count must be logged in Strava.

As of this morning, I have ridden to work 30 days since the challenge began and I am at 290.6 miles plus the 3.5 from the ride in which I can’t log until I get back home.

However, in the mean time, Garmin has announced a different toy. What I was planning to buy is a dedicated bicycle computer, a Garmin Edge 520. The 520 talks to your phone, tracks Strava segments and tells you when one is about to start, and does a bunch of other nice things. The new thing is a new version of their VivoActive watch with an optical HR monitor on the back. It does not do the Strava segments and does not have a bike mount (optical HR needs to be on your wrist) but it tracks other sports and works as a general activity tracker including resting HR monitoring and sleep monitoring. It’s also $50 less than the 520. However it won’t be available until “Q2 2016” which means I have to wait if I want that.

One final wrinkle is that Garmin products have controlled pricing so Amazon doesn’t give a better deal than REI or just buying directly from Garmin. REI co-op dividends will be available in mid March so I could use that to pay for part of it with them and get 1% back on my Amazon CC on the rest. Alternatively I could use CC points at Amazon and get 3% back there on the difference. Ultimately it doesn’t matter that much but it’s just a thing to consider.

tl;dr I did a thing I said I was going to do.

A Special Thanksgiving

My father is home from the hospital after his bone marrow transplant. He sent this to his friends and family today.

This is a special Thanksgiving for me. After 22 days in the hospital, I was released on Monday, a day early. I am resting comfortably at home. My stem cell transplant went very well. I was admitted to the William Clements University Hospital at UT Southwestern on November 2nd. I started chemo on November 3 for six days. My sister Kathleen flew in from Nashville and donated her stem cells on Monday November 9th. Her stem cells were infused into me the next day. I was without an immune system for about eight or nine days. Kathleen’s stem cells started “engrafting” into my bone marrow and by the time I was released from the hospital many of my blood cell counts were close to normal, ahead of schedule. According to the doctors and nurses, I pretty much sailed through the transplant without many of the complications associated with the procedure – never had a fever, one minimal mouth sore, no swelling or skin rashes, very little diarrhea, no signs of infection or rejection, started losing my hair the last couple of days, so I had my head shaved. I haven’t had a burr hair cut since 1957.

This Thanksgiving I have many things to be thankful for. I want to thank my parents for their love which created my sister Kathleen. She was a 100% match and was enthusiastic about the opportunity to donate to save my life. I am thankful for the love, prayers, and support of my children Eric, Eileen, my brothers Tim and Stephen. I appreciate the phone calls, support and prayers from my aunts, uncles, cousins, longtime friends in San Antonio, Boerne, Lampasas, Dallas, California, North Carolina, Missouri, and former teaching colleagues.

I am thankful to all of the medical professionals that treated and guided me through this process. What is amazing to me is that the melting pot nature of the United States led to me being cared for by doctors and nurses from around the word. Texas Oncology Presbyterian Dr. Katherine Wang – Shanghei, China, UT Southwestern Dr. Madhuri Vusirikala – India, Dr. Collins- USA, Dr, Patel – India, M.D. Anderson Dr. Kantarjian – Lebanon, nurses and technicians’ from Philippines, Trinidad and Tabago, India, Zambia, Zimbabwe, Ethiopia, Ghana, Kenya, Nigeria, Puerto Rico, England, Ft. Worth, Round Rock, Keller, and Dallas.

I am thankful to President LBJ for creating the Medicare system that allowed me to be treated without going bankrupt, charitable foundations – Leukemia and Lymphoma Society and Patient Access Network for providing financial medical assistance, President Obama for the Affordable Care Act which will prevent the medical insurance industry from discriminating against my pre-existing medical condition.

Although I never have and probably won’t ever understood it, the God that created this world with all of its beauty also has terrible diseases, yet has a hand in creating scientist and doctors that continuously improve the lives of people by curing those diseases. My sister, who had a life threatening disease, was cured by a new medication just six months before I was diagnosed with my life threatening leukemia, allowing her to be my stem cell donor. Go figure. Thanks God.

The journey continues, hopefully my body and Kathleen’s stems cells will not reject each other and I will be out of the woods and cured in about a year.

Thursday I went down to the title company, signed a phonebook’s worth of papers and bought my new house. It has been a long road and it’s not quite done yet what with the impending move and then sale of the old house but it feels good to be done and I like the new place.

export-2710

I have a list of things for plumbers, electricians and roofers to quote me on. Nothing is actually broken but it’s stuff that I want to be done to make the house safer or less likely to have problems in the future. I have also done my first chores and home improvement. I replaced the A/C filters with newer, better ones. I have also repaired the 2nd floor bathroom’s pocket door latch and latch plate. The door would barely close and wouldn’t latch at all owing to the previous hardware having been installed incorrectly. There’s a little sanding and painting to be done still but the new hardware is in place and it works properly.

The new place is a little larger than the old one in terms of square feet but it has a second floor lofted office and living space open to the first floor living / dining / kitchen. There are two bedrooms and a laundry and bath on the second floor. The master bed and bath are on the third floor, as is a roof top deck that looks out over Shoal Creek and into the west hills.

I’m going to Dallas for Thanksgiving and to see Dad so moving will have to wait until after that. I’ve taken the bicycle to the house though so I can ride it around in town instead of driving which is one of the key reasons to move to town. In fact, I’m sitting in Houndstooth writing this right now, having ridden the whole seven blocks to here.

Yesterday we learned that Dad’s transplant has gone well. His white count is already recovering and they’re planning to discharge him from the hospital Monday morning which is a full day a head of the original schedule. This is great news. My plan is to drive up there either late Monday or early Tuesday depending on how things go with the gas service turn-on Monday.

2015

Hello Blog. It’s been a long time. Last time we talked I was complaining about
how very hard it is to have a fancy car with fancy broken parts that was
engineered in a somewhat short-sighted fashion. And that’s all well and good
but the rest of this year has been a huge mess and I’ve been avoiding writing
anything about it. I should get it out there though so here goes.

One night in the middle of April my dad was not able to sleep because of
serious pain in his back. He has had back problems most of his life which I
inherited from him but this was different and after not being able to sleep all
night he went to the emergency room. They decided it was probably kidney
stones but the routine blood work turned up a white blood cell count of around
100,000 per mcL. Normal is between 4.5k and 10k. At this point the head of
oncology, who happened to be on call, came by and made him an appointment with
someone at the Texas Oncology group attached to the hospital. I went up to
Dallas and was with him when he was diagnosed with Chronic Myelomonocytic
Leukemia (CMML). The results of a bone marrow biopsy showed his “blast” cells
(immature, pluripotent immune cells that differentiate into the five white
leukocytes) were at around 18% of his marrow cells. Normal is around 1%. So,
his case was fairly advanced and they decided to begin treatment the next
week. Five consecutive days per month of Decitabine followed by three weeks
off. I stayed with him the first week and we hung out, talked and went to do
things around town.

Since then, his treatment has gone well. His immune system responded well to
the treatment. His blast cells were back down in the normal range after two
rounds. At that point the doctors started talking about the “cure”. He would
need a bone marrow transplant to kill the cancerous marrow and replace it with
something that wouldn’t produce white cells without bound. This has been very
scary for him because there’s no going back. There’s no modulation. You kill
the host immune system and replace it completely. And even if it works you may
still have to deal with rejection issues. Graft vs. Host Disease (GVHD) is
what happens when the new immune system decides that the entire host body is
foreign and mounts a “defense”. Symptoms can be mild and manageable or severe
and require extensive medication and medical care.

While all of that is going on my very good friend with whom I brew beer and
whose wedding I was in was getting ready to go to a conference in Brazil with
his wife. A week of work and a week or so of vacation with their friends who
live in Rio. On the morning of the flight, he didn’t feel good and went
downstairs to have a coffee and breakfast and to walk it off. A few minutes
later she heard a crash downstairs and he didn’t respond to her yelling down
the stairs if he was OK. She ran down and found him seizing on the living room
floor. A 911 call summoned EMS and he was taken to the hospital where they
found a mass in a head scan.

Further tests determined that there was a 6cm x 2cm – ish tumor in his right
frontal lobe. He was released from the hospital after a few days with some
anti-seizure medicine, some steroids for swelling and ultimately a date with a
neurosurgeon and a neurooncologist. He is a scientist and knows other
scientists in a wide variety of fields. He got high resolution MRI scans and
some fMRI scans of tests done while he was performing cognitive tasks. And
then he went into surgery. They removed a significant part of his right
frontal lobe but could not remove all of the tumor because a small part was in
the right temporal lobe. The frontal lobe is less important and the left side
can compensate for the loss of function. The temporal lobe is more important.

Biopsy results from the surgery produced a diagnosis of oligodendroglioma
classified at stage 2 post-surgery. So, chemo only, no radiation. But because
it is a slow growing tumor and the blood brain barrier is pretty good he will
have to be on his chemo for at least a year. It has been less easy for him
than my dad’s chemo was for him. Nausea, loss of appetite, and other issues.

In the mean time dad had been off interviewing transplant doctors and getting
consultation at MD Anderson. Dad selected a doctor at U.T. Southwestern in
Dallas to do the transplant and I went up for a meeting where they were to
discuss the transplant and post-treatment care. During this meeting she said
she had had his original biopsy from April reanalyzed and had decided that he
should be reclassified as having Acute Myelomonocytic Leukemia (a blast cell
count of 26% rather than 18%) and that this might afford different treatment
options.

AMML is often treated with a heavy dose of hard chemo to bring the disease
under control and into “remission” and then a round of consolidation chemo
which aims to knock out the cancerous marrow and let the normal marrow
recover. She gave this option a 35% chance of success compared to the 65%
chance from transplant. However, the transplant could be done later if the
chemo-only route failed. However this was dependent on finding certain genetic
markers via a broad spectrum analysis by FoundationOne.

While all of that was going they started the donor search. How to find a
donor? There is a national registry which I put myself on for preemptive
karma. But the preference is to find a sibling. Siblings are much more likely
to match on the Human Leukocyte Antigen matching scheme and there are
generally better odds of success. He has two brothers and a sister, all of
which are younger than him. One brother is out because he has already had two
cancers, one of which was treated with radiation which disqualifies you.
Radiation is a common cause of Leukemia which is what the writers call irony.
The other brother, the youngest, was not a match. The sister however was a
perfect 10/10 match.

She had had Hepatitis C for most of her life. A new drug was released at the
end of 2014 (Harvoni, I think) that had a very high rate of cure. She took the
12-week course and was declared virus free early in 2015. So, six months
later, she no longer has an incurable, blood transmissible disease and is a
perfect match and the doctors at UTSW are willing to use her as a donor.

After a month or so the results came back from Foundation. Rather than have
good markers increasing the chance of chemo-only being successful, he had bad
markers which took the option off the table. Back to the transplant. A
schedule was made.

About this time we heard that a friend who had moved away after grad school
had landed a job with Austin Community College at their new Hays campus and
would be moving back. Good news this year finally! When I heard this I
thought, “I wonder if she could get a house down there instead of renting” so
I started looking at Zillow to see what was available. Of course, Zillow is a
trap and it wasn’t long before I was looking in the neighborhoods I like in
central Austin for things for me.

As an aside, she didn’t want to live in Buda and ended up getting an apartment
in Austin north of Ben White which only qualifies as South in that it is south
of the river.

I have been saving to move into town for four years. My commute is 26 miles
each way, every day and traffic can make that a 1.5 – 2hr per day proposition
depending on when I leave. It is awful. I spend, by my calculations, two weeks
of full 24 hour days commuting every year. What would you do if you had two
extra weeks of your life every year? It keeps me from doing things and is
generally terrible. Four years ago I changed my direct deposit to put a cost
of living amount plus a few toys or trips here and there in my checking
account and the entire rest of my paycheck, more than 50% goes into savings.
Every raise and bonus has also gone to the house.

When I was browsing I saw a great place in the Rosedale neighborhood. It’s 3.1
miles from work. It’s about the size I want. It is architecturally
interesting, three stories, open plan and otherwise great for me. But it was
more than I felt I could afford. Dad had introduced me to his friends who are
building houses in their retirement and I asked them for their agent’s name
and got him to take me to the house to look around. I wanted it but it was too
much so I told him I would just wait since the owner had recently lowered the
price for the third time. I figured he’d get some interest, that would be
that, and I could go back to saving. The original plan was for five years, not
four. But no offers came and my agent got him down even more, to a price I
could tolerate if not actually be excited about.

On October 8th I went under contract and started all the inspection due
diligence and other stuff needed to buy a house. I applied for a loan which
involved summoning up a mountain of financial records and releasing the locks
I have on my credit reports. The inspection came back OK so I decided to
proceed. The house appraised for what I was buying it for. I performed the
excruciating task of shopping for insurance including reading the actual
policy contracts which even my company’s CEO, a lawyer, said “I read
everything I sign and I don’t read those anymore”. The song has been sung, the
dance has been danced and tomorrow morning at 9:30 I close on my new house.

While that’s been going on my friend’s chemo has been going along. They
got good news from their Foundation analysis in that there are a couple of
mutations that mean some ancillary treatments are possible. And on November
2nd, my dad checked into the U.T. Southwestern hospital to begin his
transplant. He had five days of a different chemo than he’d been having and
then one day of some really nasty stuff to finish the marrow off. His sister
started treatments to cause her to produce a large number of immune stem cells
and then she had a port installed and was hooked up to a blood apheresis
machine to separate out the cells they needed. Two days of that matched up
with dad’s end of chemo and one rest day and they transfused him on November
10th. The doctors and nurses referred to it as his second birthday. I went to
visit him last weekend and I’ll be going back up next week after I’ve closed
on the house. I’ll see him and my aunt who gave this gift of a second chance
and the rest of my family who is all coming in to Dallas to celebrate
Thanksgiving.

It will be good to see everyone and to be reminded of all of the things that
are good about life after the difficult year behind.

catalytic reductio ad absurdum

no-startI used to drive a 2001 Honda Accord. It was the first car I bought with my own money. I put 212,000 miles on it without it having a major problem. However, I have a pretty good job and wanted a new car so in December of 2011 I bought a 2011 BMW 335d. The D is for Diesel, specifically a twin-scroll turbo diesel that makes 265 hp and 425 lb-ft. It is also an environmentally responsible “Clean Diesel” that gets 36mpg hwy and has a veritable phalanx of emission controlling and tempering technology installed. I have found a 118 page training presentation BMW made for its maintenance staff detailing the myriad parts and how they work, down to the chemistry of the “selective catalyst reduction” in which a heady mixture of water and UREA are sprayed into the exhaust to react with the terrible acid rain causing Nitrous Oxides and turn them into H2O and N2 and fresh lavender scent.

The primary components of this system are:
The Diesel Particulate Filter (DPF) which is a metal filter in the exhaust line that collects diesel soot particles and then periodically “regenerates” itself by having fuel sprayed into the hot exhaust which ignites, heats the DPF to over 250°C and burns the soot into CO2 releasing it downstream. A DPF can become so clogged that regeneration fails. Regeneration also becomes less effective over time. The filter will have to be replaced eventually.

Exhaust Gas Recirculator
Exhaust Gas Recirculator
Exhaust Gas Recirculation which sends some exhaust gas back into the intake to burn residual, uncombusted fuel and reduce particulate emissions. The EGR manifold, valves and “swirl plates” can become caked with carbon build up over time, particularly if the car is driven at low speed for extended duration like stop and go traffic, and may require cleaning.

SCR System
SCR System
The Selective Catalyst Reduction system composed of a “passive” tank under the trunk floor which has level sensors, a sending unit and other parts similar to a fuel tank except it hold corrosive fluid which can crystallize and freezes at -11°C. (12.2°F). This tank sends Diesel Emission Fluid / Urea / Selective Catalytic Reducing Agent to the “active” tank which also contains filters, a level sensor, a high-pressure pump, pressure sensor and other parts. The “active” tank also has a heater to ensure that the DEF remains fluid. Finally there is the injector which sprays carefully metered amounts of DEF into the exhaust, and NOx sensors which measure Nitrous Oxides pre- and post- conversion to make sure the whole thing is doing its job.

The ECU and auxiliary data collection and sending systems which control the general engine function as well as the EGR valves, DPF regeneration, SCR injection via feedback loops with the various air flow, temperature, level and chemical sensors.

So here’s the problem. My car is now a little more than three years old. I have put 65,000 miles on it because I have a 50 mile per day commute plus I drive to visit family and do other things. My warranty expired at 50,000 miles at about 2.5 years of ownership and I did not purchase an extension for the warranty. A month ago the car started saying it wanted service. Then it started saying the DEF tank was low and threatened that it would not start anymore in 1000 miles. Then the “Service Engine Soon” light came on. I scheduled service and took the car in. After looking over the car for a day the dealership declared that the level sensor in the active SCR tank had failed (code 4BAC). And then things got absurd. The level sensor, which is nothing more than two closely spaced electrodes which complete a circuit when immersed in corrosive DEF, is not serviceable. You cannot take this sensor out and clean it. You cannot take it out and replace it. You must replace the entire active tank if the sensor fails at a cost of $1030.00 plus labor (another $1000-ish).

Disposable SCR tank
Disposable SCR tank

Non-serviceable level sensor
Non-serviceable level sensor

What would possess an engineer to design this thing in this way? Sensors fail. It is one of the most common things to happen in a modern car. O2 sensors fail. Fuel level sensors fail. I’m sure the NOx sensors fail. I know that the Mass AirFlow sensors fail because people are constantly having problems with them on these cars. Serviceable sensors is a basic engineering principle. You must be able to test and replace faulty measurement devices in any endeavor which relies on data collection.

I am not alone in my plight. The internet is rife with complaints about similar issues. I knew what the fault code was before I saw it on the service invoice because the internet knows what it is. I now know what the other codes are that will be thrown as carbon builds up in the EGR system, the DPF clogs, and all of the rest of the, apparently, remarkably fragile emissions control system collectively shits the bed.

However, dear reader, there exists a solution. A solution particularly particulate and possible in the fair state of Texas. We have no emissions requirements for diesel vehicles in this state. I cannot be failed at inspection for emissions on my car. This is comical. The guys in their jacked up trucks with mud tires and a six inch sewer pipe sticking out of the center of the bed as an exhaust pipe trailing a plume of black smoke the envy of an 1850’s steam locomotive are doing nothing wrong in the eyes of the law. They Roll Coal with the blessing of the statehouse.

So, if you don’t want a bunch of fiddly, badly designed shit to break and render your fancy luxury sport sedan inoperative what are you to do? Why remove it all, of course. Remove the SCR tanks, there’s a 100 pounds of corrosive fluids, tanks, pumps and shit gone. Remove the SCR catalyst. Remove the DPF and the exhaust mixing plate. Block the EGR ports. But what about the computer? It requires that these things be operational. It literally will refuse to start if they are inoperable. The ECU cares about Mother Earth even if the legislature doesn’t. Ah but ECUs are reprogrammable. Even the nasty, tamper resistant ones like equipped in the 335d.

Here’s the punchline. The reprogrammed ECU has different mappings as well. And now that the exhaust is blissfully free-flowing, freed of two separate catalytic converters, a mixing plate like a static fan rotor, and a fine metal sponge-like particulate filter, the engine can stretch its legs. Reports I’ve read put the retune at +100 hp, +60 lb-ft and +5-10% fuel economy. That’s right, it uses less fuel and makes significantly more power. The power and torque curves are flatter too. And because the engine is tuned properly it still won’t leave a cloud of black exhaust. Though you could manage that if you leave the DPF regeneration fuel injector in line.

So what to do? Keep limping the emissions controls along? Write my futile nastygrams to BMW of North America and hope for recalls and the fabled “Good Will”? Or spend an equivalent amount, delete it all, get a Calvin-peeing-on-Mercedes-logo window decal, a BAVARIA SHALL RISE AGAIN! bumper sticker and a horn that plays Dixie in the key of Tuba? I know which way I lean.

Pizza

Today is home-made pizza day.
Pizza 1/3

Pizza 2/3

Pizza 3/3

I did the baking on a 12″ x 12″ x 0.25″ piece of steel that I’ve seasoned. I preheated the oven to 500°F and let it soak heat for about 20 minutes longer and then put the pizza in. Getting it off the make-shift peel was a little rough but other than that it was ok. The broiler wouldn’t come on which says to me the top of the oven was hotter than 525°F. Still, after 6 minutes and change the bottom was not very brown and the edges, cheese, and pepperoni weren’t either. It tasted great but I think I can do better next time. I guess I’ll do it again tomorrow since I have five more dough balls.
