Pug Meets Baby


You should have seen Puggo yesterday. Lindsey’s husband, Matt, is a KISS fan and wanted see the lit guitar, so we all agreed to meet for brunch and I brought the guitar to John’s house. Jack brought the RepRap and we showed off our advanced in technology. Lindsey and Matt have a 14 month old baby, a little girl who is cautious about the notion of walking but she crawls very well. Lindsey put the baby down on the floor and Puggo came up to see what kind of Pug-sized creature was perched on all fours on Puggo’s turf.

Puggo sniffed and licked at the baby’s face; the baby giggled but eventually pushed at Puggo’s snout, then started to crawl across the rug. Puggo was entranced! Puggo gave the “PLAY with me!!” crouch, then raced into the living room. Puggo circled the interior of the house several times, barking happily. The baby sat down,  her diapered bottom plopped firmly onto the rug, and watched the dog in curiosity. Puggo would approach the baby to sniff and lick at her face, then race off, daring the baby to chase her. The baby wasn’t as quick as the Puggo, even if she was a skilled crawler. Still, Puggo was ecstatic to have someone close to her size and form on the floor; someone who wasn’t a feline.

Puggo’s little curled tail wagged furiously whenever the baby looked her way, so much so that Puggo’s whole rump wagged. We got out Puggo’s stuffed chicken toy from the basket, the chicken with the squeaky in the head, and handed it to the baby. The baby waved it happily but didn’t want to share with Puggo. She kept it away from the dog, grinning and giggling, occasionally saying, “No!” and “Chicken!” The baby even chewed on the chicken. The baby should develop a strong immune system! 

Neither deep literature nor instruction in the Geek Way; just an observation of what I found humorous yesterday.  Some posts are like that.

Suicidal wildlife


The doe eyed the passing traffic warily as it delicately tongued the newly sprouted leaves into her mouth, delicately stripping the low-growing branch. A large dead buck laid nearby, on the side of the divided highway, semi-dried ropes of intestines sprouting from its ruptured abdomen. Connecticut Route 15 is known as both the Merritt Parkway and as the Wilbur Cross Parkway, depending on where you are. I had entered the road at I-91 but hadn’t yet reached the tunnel at New Haven, so I was still on the Wilber Cross when I saw them, the bodies spread out over a stretch of about 15 miles. These were the fourth and fifth deer that I had seen since the interchange from I-91, but the first live one, still seemingly pausing for a snack before leaping to its doom. Maybe, on this day anyway, it wouldn’t jump. Did the doe have a fawn lying in the grass, nearby? If it did, I didn’t see it. There was still one more deer carcass next to the road, a few miles before I reached the tunnel, then, much to my surprise, no more. 

Why so many suicidal deer along such a short stretch of highway, I don’t know. It was early morning and I had to get to Philadelphia by noon. I drove carefully, uncertain if other wildlife might attack my car as it sped down the road. 

 Why was I driving to Philadelphia? That's another story. For this episode, suffice to say that I reached my destination and returned, later that night, physically unscathed. No animals were injured in the process.

It's been a long time but I've been busy!


       Sometimes, I get really annoyed.
       I visited family graves last weekend and took a number of photographs of head and foot stones. I started my trip in Granby, MA, where my father’s family is buried, as are my brothers. Danny was twenty years old and schizophrenic; one winter weekend, he went off camping, to get away from the demons that only he could see. There had been unseasonably warm weather at the end of January, with days hovering around 60 degrees. On the night of February 1, the temperature dropped precipitously as a cold front came in; the nighttime temperature dropped into the negative digits with 40 mph winds. Danny didn’t have a chance. He froze to death, a few hundred yards from the nearest road, struggling to reach it, crawling when he could no longer walk, as evidenced by the scuff-cuts on his poor hands and knees. 
       Danny was joined by our brother, Paul, several years later. Paul was a good-time guy – everybody loved Paul and Paul was the life of any party. One night, coming home from a bar, only about half a mile from where Danny died, he apparently fell asleep at the wheel. He wasn’t wearing a seatbelt when his truck hit a tree and rolled over. Paul probably never knew what happened and never felt any pain after his neck snapped (a “hangman’s fracture” - he was unable to breathe with the injury and suffocated in minutes). I miss them both terribly, even though they both died so many years ago.
       My father and his parents lie nearby. I never knew my grandparents. My grandmother died a few days after giving birth to my uncle; she had already given birth to five children. The family story is that her doctor was a cocaine addict and had used it just before getting word that she was having a difficult labor. He didn’t come for another day; she had been in active labor for several days at that point, non-stop, and it is surprising that the baby was still alive. The doctor delivered my uncle but my grandmother died – whether from blood-loss, exhaustion, heart failure, infection,  or something else – a day or two later. My grandfather sent the baby to a neighbor to raise for a year, and then pulled his only daughter out of school at the age of 13 to raise her baby brother. He also pulled my father out of school at the same age to work on the family farm. My dad became estranged from his father when he married my mom – my grandfather – a German Protestant immigrant - considered it unforgivable that my father had married an Irish Catholic. My grandfather died shortly before I was born. I don’t know if he and my father ever really spoke again, although my grandfather did not disinherit my father.
       My dad died suddenly about fifteen years ago; he was at his vacation home in Maine when he got sick. He had a silent and undiagnosed diverticulum and it suddenly ruptured (the same thing happened to me two years ago). He became septic and needed emergency surgery. During the surgery, his heart went into a rhythm incompatible with life and, although his surgeon finally shocked his heart into a normal rhythm, my dad had suffered irreparable brain damage from the lack of oxygen for the fifteen minutes when his heart wasn't pumping blood properly. We waited a few days to see whether he would wake up (he didn’t), or even start breathing on his own (he didn’t). As a family, we decided to terminate his life support and he died a few hours later.
       Ironically, my dad had had a serious argument with his older brother the previous week, just before my dad left for Maine. My uncle was dying of cancer and wanted to settle the disposition of the family farm, which was held in common by the three living brothers (my dad, my dying uncle, and the “baby” who had lived when their mother died). My uncle was used to getting his own way and, for a change, my father did not want to acquiesce. My uncle said, melodramatically, “You’ll just have to settle this with my heirs!” My dad was incensed and said, “How the hell do you know that you’ll be the first to die?” My uncle had snorted and my dad left. They never spoke again. My uncle was utterly grief-stricken at my dad’s funeral, and he followed my dad a few months later.
       Whenever I visit my dad’s grave, I am also visiting my uncle’s grave. They are interred in an eight-person lot; my grandparents, my uncle and aunt, and my father are all buried there. There is still room for my other uncle, his wife, and for my step-mother to join them (my step-mother died last year but her children have not yet decided to bury her ashes).
       What annoys me is my position in that family. I now have reddish hair (courtesy of Lady Clairol) but I really feel like the red-haired step-child, despite being a blood relation.
       When my parents divorced for the first time, my father did something unforgivable. He was angry at my mother and took it out by accusing her of infidelity. Not only that, but that I (the youngest) must have been the product of “her affair” with our only neighbor’s son. The fact that I have ALWAYS looked frighteningly like my father was irrelevant; he was mad. So mad, he told my uncle, his older brother, that I wasn’t his. And from that moment onward, I was treated like the red-haired stepchild. I didn’t understand until I was a teenager. No one who knew my mother would have believed such nonsense but, as I said, my father was very angry with her for having the audacity to leave him, not once, but twice. The first time, she realized that she had no means of supporting us so she went back to him and back to college, to get a teaching degree. Eight years later and gainfully employed, she left him, this time for good. I was twelve.
       My uncle was the worst. Once my mother came back after the first separation, my dad stopped claiming that I wasn’t his - he had always treated me like I was his favorite child and this didn’t change. My uncle was another story and an ugly one, at that. At the town fair a few months after my parents separated for the last time, I saw my uncle and called a greeting to him. He ignored me. I was puzzled; did he not hear me? I shrugged and played some of the games, then saw him passing by again. A second time, I called out to him. He continued walking and appeared to have not heard me. I thought that he must be going deaf! When he passed by a third time, I walked up to him and said, clearly, ‘Hello Uncle! How are you?” He looked me in the eye, then pivoted and walked away. I was crushed. I was no longer his niece. Only then did my big sister tell me about the terrible thing that my father had said, eight years earlier.
       I saw my uncle a number of times afterwards, always in my father’s presence. I was always polite. He was cordial but I was little more than a stranger to him. I was never invited to any family functions, except the ones that my father hosted. My cousins all married; I wasn’t invited. His children are adults with children of their own and they have hosted a number of “family” reunions. I’ve never been invited, despite living only a few miles away from the old family farm. They don’t know me or my son, yet they are very close to our other cousins.
       Amusingly, one of my uncle’s sons, my cousin, became a local cop. He called the department of anthropology for assistance in identifying some skeletal remains. I was sent to identify the bones. They turned out to consist of the forelimb of a deer, nothing human. He never said anything about our relationship and neither did I. Afterwards, I just chuckled.
       I have another uncle, the “baby” who lived. He has an email list, to send various funny or political items, and I’m on it despite his being a rabid Republican and me being a liberal. We correspond occasionally. I still feel estranged – this uncle has lived in the south for my entire life and I’ve only seen him a few times. In the last few years, he built a vacation home on the property of the family farm, but in that time, I’ve only seen him once. I still feel like I’m the red-haired step-child. Now, I have the red hair, at least!

Socks!


          I have new socks. 
          I’ve been looking for a source for the all-cotton ankle socks that I like to wear with my New Balance sneakers, under trousers. I always wear New Balance shoes because they have a support system for people who tend to twist ankles, one that usually works for me. I like either all-cotton or silk socks; my feet are always sweaty and synthetics make me feel like I’m sloshing through puddles, inside my shoes. I used to buy socks from almost any retail outlet – Hanes, Fruit of the Loom, and store-brands all had multipacks of white, all-cotton socks until a few years ago. Then, gradually, my sources dried up, one after another. My last resort was one of Walmart’s store brands – I can’t remember which. About 18 months ago, they changed to polyester and my sources were no more. I’ve been looking ever since as, although I stocked up during the heyday period, my stash of socks was increasingly becoming depleted, so much so that I no longer had a full week’s supply and most of the remaining socks were becoming very threadbare.
          I’m no longer hoarding my clean socks; I discovered that one of Amazon’s suppliers offers Buster Brown brand socks for a reasonable price. I ordered a dozen pairs and was pleasantly surprised to discover that they are made from a much finer thread than I am used to; they feel like silk socks (which were my favorites but much too expensive for daily wear). They have no elastic, so they fall down, but that’s all right. They are absorbent. And they feel good without breaking my budget!
          I’m very fussy about the clothes that lie next to my skin. All-natural fibers are best. Cotton and silk feel good. I once had a wool shirt that had such smooth fibers, it was warm but didn’t scratch, but usually, I wear cotton or silk under woolens, to protect my skin. Most synthetics feel bad. Real polar fleece (made by Malden Mills) is an exception to my general rule of avoiding synthetics, but even it makes terribly sweaty socks (unless you are in a cast, with otherwise bare toes sticking out in the cold, the way I have been, lately!). Some combinations of fibers are all right but most are just trying to disguise the horrid sensation of the synthetic part while taking advantage of their cheap cost. Mostly, the combinations are not as good as all-natural fibers.
          So why am I writing about socks? Socks are very important for foot health. I’m very pleased to have new socks; now, I have an adequate supply of all of the necessities – panties, bras, and socks. I didn’t have to compromise my personal comfort for either price or availability. I’ve got plenty of nice, new socks! New socks, new socks, new socks!
          Maybe now would be the time to go through my drawers and get rid of all of the socks that I’ve bought at different times and rejected as uncomfortable, once I opened the package and tried one on. I’ve probably got a couple of dozen brand-new pairs that I hate and will never wear. Maybe my local shelter would like them as a donation. While I’m at it, I should weed out the worn-out, the wrong sizes, things with stretched-out elastic, and the other rejects of my underwear collection. These might not be good for a donation but it would do me good to have space in my closets and drawers. Anyone need to make a bunch of sock puppets? Let me know and wish me luck!

Trying something new

I thought I might try blogging from my tablet, today. I'm too lazy to set up my laptop and my desktop is having a bad year. It's not as easy as I might have wanted but it DOES work, albeit slower than using the keyboard.

I've been thinking about some of my habits; I have a phobia of running out of toilet paper, a phobia well-engrained in my brain from repeated encounters with paperless public restrooms and a childhood where a box of tissues on the tank, to substitute for a roll, was a not-uncommon occurrance. Whenever I go to Walmart, I buy another 12 pack of double rolls. Two-ply, of course, one-ply is too prone to breakage during use. when the bathroom closet overflows with rolls, I force myself to stop buying but it's a struggle. Eventually, the stash drops down to a single 12 pack and I start to fret. A quick trip down the paper products aisle and I feel better, but I find myself buying more and more packages and the cycle repeats.

I also like to have a month's supply of panties and socks, particularly since the washing machine kicked the bucket. I like to wash clothes once a week, but sometimes, it just isn't feasible. I've never needed the whole month's supply but I like to know it's there. I can't afford a month's worth of bras but I have about a dozen.

I'm very particular about my underwear and socks. I only like all-cotton bras; I've found a sports model that I like but it has a cheap zipper in the front. The zipper doesn't latch so it can slide down. I find myself yanking the zipper up, repeatedly. I've pulled the zip off of several, while the bras were still pretty new. I figured out a solution, though. I cut off all remnants of the zipper with an exacto knife, then pounded eyelets into the edging on both sides of the opening. Finally, I bought some appropriately colored shoe laces and laced myself in. It looks a little kinky but I feel secure and comfortable. I buy my panties at Cacique; no itchy labels and they are usually pretty well-made; if I pull off the elastic, I can sew it back on without it looking mended. Socks are a challenge.

I used to buy socks easily. I could get cheap white all-cotton socks that folded over at the ankle, made by any number of hosiery manufacturers. I like cheap identical socks because I don't have to worry about matching them up after they come out of the dryer, and white because it matches almost everything. Now, most cheap socks are polyester ankle-highs. I hate them. I like to bleach my socks every few weeks and polyester either gets hard or it melts with this treatment.  They make my feet sweaty and I hate anklets! I bought several packages of cotton socks a few years ago but those have almost all passed the way if all socks, either with holes at the big toe and heel or just vanishing into the black hole in the dryer. I don't know what I'll do when the last is gone! Maybe I can felt some out of all of that toilet paper....

Repairing an alarm module in a Bentley


I haven’t written for a while because I’ve been busy with my four part-time jobs! Once of them has me working at Robison Service, listing items for sale on eBay and occasionally, doing other odd jobs. 

John has written in his car blog several times, lately, about the problem of Bentley and Rolls Royce electronics modules and the batteries on them that start to leak over time. This alarm module came out of a 1996 Bentley Continental. Bentley only made a few hundred of these cars and is no longer making components for them.  The controls are easily damaged when the batteries inevitably begin to leak and Bentley’s stock of new replacement units has been depleted. Since these control units are no longer available from Bentley, there is no choice but to repair them when they go bad, although some preventative maintenance of replacing the batteries is preferable to trying to fix one after it has gone bad. This one has gone about as bad as they get. 
 
You can clearly see that the dark blue battery in the middle has leaked badly, causing a great deal of damage to the top of the circuit board and destroying copper paths. There is a second battery, teal in color, in the lower right corner. This one had also leaked and damaged traces, although not in such an obvious manner as the dark blue battery. I’m pretty good with electronics and I have the patience to debug such disasters, so John asked me if I could try to repair it.
The first thing I did was unsolder and remove the batteries carefully, wearing nitrile gloves to keep the leaking electrolyte from burning my skin. Leaky batteries and their detritus can be very nasty.

With the batteries removed, the damage is more apparent. I used a Sharpie to mark the battery specifications on the board, in case I lost the piece of paper that I had used to record their information. I like to put vital information in more than one location because I lose paper.
You can see that there are even traces missing from the bottom side of the circuit board, where the electrolyte leaked through some of the component holes in the board.  

I wanted to remove the blue connector on the bottom side of the board, to make sure there weren’t any damaged traces under it, but I didn’t have the proper unsoldering tool. I looked carefully with a flashlight and my magnifying glass and decided that I might not need to remove it, so I left my final decision about it for later.
Next, I needed to know what kind of electrolyte remained. Electrolyte can be either a strong acid or a strong base. It depends on the type of battery. The dark blue battery was Nickel-Cadmium (NiCad), while the teal one was nickel metal hydride (NIMH). I went to Wikipedia and looked up both types of battery. I discovered that they both utilize a basic electrolyte, so my first plan to neutralize the remnants with baking soda wouldn’t work; I needed a weak acid. I chose vinegar because it is safe and I had a gallon jug of the stuff in my pantry. I raided the bathroom closet for a big box of Q-tips.
I poured a bit of vinegar into a small cup and dipped in a Q-tip, then lightly scrubbed at the stain. It bubbled vigorously. I discarded the Q-tip and repeated the process until I had cleaned both sides of the board, a process that took several hours. The stains only bubbled in a few places and only the first time I wiped them but, eventually, the tarnish also began to come off. As I scrubbed, I repeatedly moistened the edge of the blue connector (on the bottom side), encouraging a bit of the vinegar to slip under it, to neutralize any possible electrolyte remaining under the connector. I used more vinegar swabs to clear off the dusty bits from components on the adjoining circuit board. I was patient because I wanted every speck of electrolyte cleaned off of the board before I tried to initiate repairs.
Now that everything was nice and clean, I was ready to start tracing the paths of the damaged copper foil. I scratched at some traces, to gauge how deeply they had been etched by the electrolyte. Some came off entirely. I started by trying to replace the traces, but gave this up when too many traces turned out to be only a few molecules thick - that's when I started to systematically scratch at them with an exacto knife, to test their solidity. 
.
I used 30 AGW wire to replace most of the traces. For the power traces, I used a heavier gauge wire. The small blue rectangles are capacitors; the larger black components at the bottom are diodes and the bigger black rectangles are relays. There wasn’t any logic, to speak of, on this board, so I was fairly sure that if I just replaced the broken connections on the board with wires, the board would function properly - individual components are inherently sturdier than logic components, which contain many interior components. Some traces moved from one side of the board to the other via little plated holes; I decided that merely connecting their ultimate ends was a more efficient means of repair.
For some of the top traces, it was easier to just connect the components on the bottom of the board.
I couldn’t find exact voltage replacements for either of the batteries at Radio Shack. I needed a 6 volt Ni-Cad and a 4.8 volt NIMH. I did find 3.6 and 2.4 volt Ni-Cads and 2.4 volt NIMH batteries. I connected two batteries (of the same technology) in series to add up to the correct voltages (the amp-hours were a little higher than in the originals but that shouldn’t create any problems). All four replacement batteries were meant for cordless telephones. I taped the pairs together, connected one red to the other's black to add the voltages in series, cut off the remaining connectors, and soldered the packets in place.

Once the unit was folded back together and the clips safely secured, the module was ready for Buddy to re-install it in its car and test it.
 
It worked properly. Another problem solved.

Autism Spectrum, Prosopagnosia, and Empathy

I'm surprised to discover that I haven't blogged for almost two months, after blogging almost compulsively in September. I've gotten a couple of part-time jobs and am now pretty busy all of the time, either driving or working or thinking about the various tasks I have to perform. Still, I find myself needing to blog. Here's my latest thoughts.


I didn’t want to accept that I was on the autism spectrum. I hated the very idea of it. Come to think of it, my recent reaction to the gastroenterologist’s conclusion that my year-long bout with diarrhea was probably the result of gluten intolerance was remarkable similar to my realization that I was on the spectrum - a lot of tears and anger, followed ultimately by reluctant acceptance.
                This is what happened.
                John asked me to complete an online questionnaire for the Cambridge Autism Research Center, headed by Simon Baron-Cohen. John wanted me to complete it as he had done so and had referred Jack (one purpose of the study is to track the incidence of autism spectrum in biological families). Since Jack has also been diagnosed as being on the spectrum, John wanted me to fill out the questionnaire as Jack’s mother. I followed the link in his email, filled out my complete contact information, and started answering questions.
                I was immediately struck by my responses to a number of the questions. I knew how “normal” (neurotypical) people would answer them but I had to be honest – and my answers didn’t look at all “normal” to me. There were three different test instruments, each about sixty questions long. As I considered the totality of my answers, I grew more and more uncomfortable. Although I was alone in the house and sitting at my desktop computer, I suddenly cried out loud, “I’m fucking autistic!” and burst into tears. I sobbed uncontrollably for a few minutes, then wiped my face and blew my nose. I finished the survey and the results came immediately.I wasn’t surprised.
                Although not an official diagnosis by a trained psychologist, the response said, there was a strong probability that I, like John and Jack, was on the spectrum. Was I willing to give contact information for my siblings and/or parents? I cried some more. I thought about my immediate relatives as I found a box of tissues in the bathroom closet. My mother was no longer capable of responding to such a query so I didn’t put her down. I did give contact information for my sister, Karen, and my brother, Ed. Karen opted to not take the survey. Ed did and, shortly after, he emailed me with his scores – they were even lower than my own. He was also probably on the spectrum. I felt better immediately. Misery loves company.
                Despite the time (it was after midnight EST) I immediately called Ed to discuss the survey. I was still very upset. He wasn’t surprised by either of our sets of scores. As we chatted over the next three hours, we discovered that we also shared an inability to recognize or describe the physical appearance of others. I’ve since discovered that lot of others, although not everyone, on the autism spectrum share this “face-blindness.” Oliver Sacks discusses it at length in his book, “The Mind’s Eye.” He gave it a $500 name – prosopagnosia. I had always thought that I was defective and that I had to hide my inability to recognize people. I thought I was alone with this handicap. Now, I wasn’t the only weirdo in the world. It’s amazing how sharing either a gift or a deficit can raise your spirits – and it wasn’t merely company for my misery – it was the knowledge that this essential part of me isn’t only mine, exclusively - that i wasn't totally wierd! I’d always tried to disguise it and now, I didn’t have to! I can say it - I have prosopagnosia.
Actually, I’ve got a better face-memory than many others with face-blindness – although I can never describe the appearance of anyone that I haven’t (explicitly) verbally described while they were in front of me, I can still recognize the people that I see on a regular basis. I can even remember a lot of these people years later, although I can’t put names to them. If I’ve gone to the trouble to remember someone, I really remember them! I just have trouble entering them into memory in the first place. I rarely remember people’s faces until I’ve met them multiple times (or taken their photograph and studied it). I’ve been unable to distinguish people that I’ve worked with for an entire day on the following day unless I’ve used my own methods for remembering them. I CAN remember them; it's just very hard work.
Empathy
I have trouble with Simon Baron-Cohen’s assertion that people on the autism spectrum have little or no sense of self – for example, that they do not understand that others do not share their knowledge. I have certainly been guilty of this but there is usually a good reason for my assumptions. I was utterly amazed that the crew of the Learning Channel’s program thought that how John thinks is unusual – I tried to explain that many of my acquaintances and members of my family have similar ways of understanding but they didn’t want to hear it. 
Since it was unusual to them, it MUST be extraordinary. I tried to explain that normal is only the average of your personal sample  of the people that you typically encounter – but my sample is not the same as their sample. My sample is probably not representative of the population. If you lived in a town with a high number of functional mentally retarded people, you might think that any degree of creativity is extraordinary. My sample is from the opposite end of the spectrum, so my assumptions about what “most” people know is reasonable, given that most people of my acquaintance are people of considerable talents. 
Most people of my acquaintance DO share my level of knowledge! I know that others may have fewer opportunities to expand their knowledge base but, if I’m talking to them, it’s usually because they are my students and I’m supposed to help them to understand more and I am trying to push them to excel. Everyone has some culture shock when they encounter people who do not share their system of beliefs and common knowledge. Neurotypicals are not assumed to have no sense of self as a result of that culture shock!
I have the ability to put myself in another person’s position, commonly called empathy. I just have a very hard time trying to figure out what people are thinking on the basis of their visual cues. With my face-blindness, I have trouble with situations that require me to interpret complex visual data. Baron-Cohen would not call a truly blind person non-empathic; why am I considered by him to lack empathy because of my visual deficit?
