Well, that would be Victor Gabriel Toth, not me, but nonetheless, it is still creepy to see an obituary in the Ottawa Citizen containing, albeit with a minor spelling variation, my name.

I never met this Victor Toth, even though at one point, I was told, I might have been working just two floors above him at the Nortel building on Merivale Road, a building in which several floors were rented by Canada Post.

Well, Victor Toth, you had a long life and, I hope sincerely, a happy one. I hope your family is not so much grieving as celebrating your long life.

Then again, I also sincerely hope that I won’t be following in your footsteps anytime soon, as I have plenty more to do in this world before it’s my time to depart.

Yesterday, we said goodbye to our old car, a very nice Honda Accord that served us faithfully for four years.

The lease expired, so we opted to lease a new one. Another Honda Accord. (Incidentally, 2018 marks the 30th year that I’ve been purchasing Hondas, from this very same dealership.)

The old car was nice. The new car… Well, it’s amazing what even four years can mean these days when it comes to vehicle automation.

The level of automation in this vehicle is amazing. It can start itself, it can steer itself. It has full situational awareness, with radar all around. Apparently, it even monitors the driver for alertness (I’ll have to read up on exactly how it accomplishes that.) During the short drive home, it once applied the brakes when its adaptive cruise control was on and someone moved into the lane ahead of us. It was braking a little harder than I’d have preferred, though. And at one point, as the lane markings were a little ambiguous, it gently resisted my attempt to depart from what it thought was the correct lane.

In principle, it appears, this car has all the components for it to be fully autonomous, except that perhaps its array of sensors is not sufficient for it to be fully safe. But really, the only thing missing is the software. And even the way it is, it is beginning to feel more like a partner in driving than a dumb machine; a partner that also has a well-developed instinct for self-preservation.

Welcome to the future, I guess.

Our kitty Pipacs is still doing okay.

Today, he managed to show the oddest of faces when my wife attempted to take a picture:

Don’t worry, he was just yawning.

What we haven’t seen is any poop from him in the past 36 hours or so, and he seemed to be a bit under the weather at times. I hope it doesn’t mean that his bowel is obstructed again. We know he’s living on borrowed time, but we hope that there is still a little bit more time out there for him to borrow.

Anybody interested in hiring a competent TV repairman?

No, just kidding. Nobody makes a living from TV repair anymore. (On the other hand, if you are interested in hiring a competent IT contract professional… but I digress.)

Still, I have this compulsion, trying to repair broken things even when they have little or no practical utility. So it came to be that I felt compelled to repair this old SANYO AVM-2664U analog 26″ CRT TV, with a circuit board that was buzzing louder than a hive of angry wasps, as shown in this thermal infrared video which I made while I was hunting for possible hotspots on the circuit board:

Eventually, I managed to track down the problem: One lousy little capacitor.

As I told my wife, it would be fun, doing this for a living. Unfortunately, nobody is likely to pay hundreds, maybe even thousands of dollars to repair an old television set that not even thrift stores want anymore (too heavy, too obsolete). Yet another perfectly useless skill in the year 2018.

There is a very interesting concept in the works at NASA, to which I had a chance to contribute a bit: the Solar Gravitational Telescope.

The idea, explained in this brand new NASA video, is to use the bending of light by the Sun to form an image of distant objects.

The resolving power of such a telescope would be phenomenal. In principle, it is possible to use it to form a megapixel-resolution image of an exoplanet as far as 100 light years from the Earth.

The technical difficulties are, however, challenging. For starters, a probe would need to be placed at least 550 astronomical units (about four times the distance to Voyager 1) from the Sun, precisely located to be on the opposite side of the Sun relative to the exoplanet. The probe would then have to mimic the combined motion of our Sun (dragged about by the gravitational pull of planets in the solar system) and the exoplanet (orbiting its own sun). Light from the Sun will need to be carefully blocked to ensure that we capture light from the exoplanet with as little noise as possible. And each time the probe takes a picture of the ring of light (the Einstein ring) around the Sun, it will be the combined light of many adjacent pixels on the exoplanet. The probe will have traverse a region that is roughly a kilometer across, taking pictures one pixel at a time, which will need to be deconvoluted. The fact that the exoplanet itself is not constant in appearance (it will go through phases of illumination, it may have changing cloud cover, perhaps even changes in vegetation) further complicates matters. Still… it can be done, and it can be accomplished using technology we already have.

By its very nature, it would be a very long duration mission. If such a probe was launched today, it would take 25-30 years for it to reach the place where light rays passing on both sides of the Sun first meet and thus the focal line begins. It will probably take another few years to collect enough data for successful deconvolution and image reconstruction. Where will I be 30-35 years from now? An old man (or a dead man). And of course no probe will be launched today; even under optimal circumstances, I’d say we’re at least a decade away from launch. In other words, I have no chance of seeing that high-resolution exoplanet image unless I live to see (at least) my 100th birthday.

Still, it is fun to dream, and fun to participate in such things. Though now I better pay attention to other things as well, including things that, well, help my bank account, because this sure as heck doesn’t.

Our smallest cat, Pipacs, continues to do well.

Four weeks ago, we thought we were on a death watch: The kitty was severely ill, no longer able to poop as his intestines were blocked by an invasive bone growth. Laxatives, even several enemas were of no use.

We were convinced that the only alternative to a slow, painful death was euthanasia.

But then, he suddenly pooped. (What a relief. Especially for him.) Since then, we’ve been able to manage him with medication.

I don’t know how long he will still be with us, but for now, he is doing okay. The bone growth distorting his pelvis is quite large now, making it all but impossible for him to use one of his hind legs, but it doesn’t appear to bother him too much, except when he is trying to use that leg to scratch an itch. Just watching it is frustrating! (How do multiple amputees scratch themselves when they have to?)

But he is eating well, he is pooping well, and when the other cats aren’t chasing him around, sometimes he chases them instead.

Here is a beautiful picture of the contents of one of our litter boxes:

What makes it beautiful, you ask? Why, it is a thermal infrared image. And it shows some unambiguously fresh poop. Fresh poop produced just a few minutes prior by our kitty Pipacs, whom we were about to write off two weeks ago, as we were certain that his digestive system shut down, him being unable to poop as his bowels are obstructed by an invasive bone growth.

But Pipacs still has a few of his nine little lives left. I don’t know how long he’ll stay with us; we take it one day at a time. But with the medication he receives (a combination of laxatives and stool softeners) he is coping for the time being.

Concerned as we were (and still are) about the health of our smallest kitty Pipacs, it helps to remember that we have two other felines in the house, both in good health as far as we know (fingers crossed and all that.)

The orange tabby on the left, Kifli, will turn 17 in April. He will be old enough to vote in next year’s federal election! He has not stated his political preference yet.

And despite their similarities, the two cats are not related. The cat on the right, Rufus, was a stray. He was approximately one year old when we adopted him in the fall of 2014.

Much to our surprise, not to mention relief, our kittycat Pipacs is a lot better today.

We noticed yesterday afternoon: he began eating again. He seemingly felt better. He groomed himself. He even played with us a little.

And then this morning: a nice, big poop in the litter box.

So his digestive system is functioning again. Probably with difficulty, so he is going to be permanently on a diet of laxatives and stool softeners, but so long as he is able to poop, he should be okay as otherwise, other than the bone growth on his pelvis, he is healthy.

This bone growth is not going to go away, so we’re living on borrowed time. But borrowed time is still a lot better than no time at all.

I already called the vet and canceled the scheduled visit for tonight. Thinking of Murphy’s law, however, I asked them not to process a refund yet, just keep the amount we already paid on our account.

This beautiful creature, who has been our companion for ten and a half years, give or take, is Pipacs (Hungarian for Poppy, pronounced pi-patch or something like, with the ‘i’ as in the word hit, the ‘a’ in the word bark, with emphasis on the first syllable.)

Unfortunately, Pipacs is very ill.

He was diagnosed with a growth on his pelvis three years ago. Even back then, the only treatment option was drastic surgery: Removal of a large part of his pelvis along with the leg on that side.

Pipacs has always been a very skittish cat. He was a stray when we adopted him, probably about a year old in late summer 2007. He is very easily traumatized. This, and the very low risk of such a growth spreading to other organs led us to the decision not to opt for surgery.

One thing we did not anticipate is that the growth, which increased in size rather dramatically in the past few months, would encroach on his digestive system and eventually obstruct his colon.

Which is exactly what happened. Simply put, beyond incidents of explosive diarrhea after receiving enemas, Pipacs cannot poop anymore. And sadly, surgery is no longer a viable option.

Which is why our veterinarian is scheduled to make a home visit tomorrow with her euthanasia kit. And my heart breaks as I am writing these words.

When will news portals finally learn that autoplaying a video at maximum volume in the middle of the night guarantees only one thing: that I close the tab in a mad panic while I curse the news site, its creators, editors, their parents and grandparents and just about everybody they ever did business with for scaring me witless and waking up my household?

It’s the same, each and every Christmas. As Christmas Eve approaches, I remember that famous moment from 49 years ago. The astronauts of Apollo 8 just orbited the Moon. It was Christmastime. These three men were a thousand times farther from the Earth than any human being in history. It was an awe-inspiring moment. Once radio contact with the distant Earth was re-established, the three astronauts took turns reading the first ten verses of Genesis. Frank Borman then closed the broadcast with words that, in my mind, remain the most appropriate words for this evening: “good night, good luck, a Merry Christmas – and God bless all of you, all of you on the good Earth.

And since I seem to be posting cat pictures today, here is an “artistic creation” of Google Photos’ AI bot, depicting our youngest cat, Rufus:

I think this picture clearly explains why we often address this feline as Master Rufus.

OK, I published a picture of Pipacs yesterday, so here is our oldest cat, Kifli, who turned 16 earlier this year.

I think he is a very respectable fellow, but he is also very playful, especially considering his age. I hope he remains this way for many more years to come.

It may not be obvious, but this amorphous thing in this picture is a cat.

This is Pipacs (Hungarian for Poppy), our smallest cat. He is a little over ten years old (exact age unknown, as he was a stray.) He was diagnosed with a bone tumor a couple of years ago, but after the doctor explained that for cats, bone tumors rarely metastasize, we decided to take a risk and not have the leg in question amputated. The main reason is that Pipacs is a very skittish kitty, and we were deeply concerned that such a drastic operation (not to mention multiple, often painful vet visits) would have traumatized him.

So far, so good. That was two and a half years ago. Fingers crossed, but although the growth is there and quite noticeable, accompanied by a small limp, it does not seem to bother him. He remains active, with no signs of pain or discomfort, and no indication of any trouble. We just hope he will stay this way for many more years to come.

Our townhouse was built in 1981 or 1982. It came with a washer and a drier installed. When we moved in, just over 20 years ago, those machines were already nearly 15 years old, but still working flawlessly.

Many years later, the washer developed a problem: A pressure regulator valve in it failed. A technician temporarily fixed it by bypassing the valve and just turning the shutoff valve to reduce the pressure. He didn’t even charge us for this work; he said he’d be back once he had a chance to order the right replacement part. He never did, and as he was one of several technicians I called from the Yellow Pages that evening, I could not even remember who he was. So I never got a chance to thank, not to mention pay, him for his labor.

The temporary solution then became permanent. The washer worked well for many more years. Until Saturday morning. Just as my wife, on her way to a craft show, was trying to wash a few freshly knitted hats, the washer refused to spin and refused to drain the tub.

I was somewhat hopeful that the cause was just a bad interlock switch, which is designed to prevent the washer from operating with the lid open. This switch stopped functioning a while back; the washer ran always, lid or no lid. But who knows, perhaps now the switch failed in the open position? I opened up the old beast, located and removed the switch and bypassed it.

It could have worked. In fact, it almost did. With the switch bypassed, the washer was no longer completely silent when it was in the spin/drain position. The motor buzzed.

But only buzzed. That angry, 60 Hz buzz that you hear when a motor is seized. And sure enough, after about 15 seconds I began to smell, and then see, acrid smoke.

This was the moment when I knew that after a remarkable 35-year run, this old White–Westinghouse washer had its last wash. It was, unfortunately, finished.

So then came the annoying task of having to find a new washer. Fortunately, I was prepared, as I already contemplated the possibility that our old washer might die (35 years!) Lately, I stumbled upon a brand: Speed Queen. It appears that they mostly make commercial washers, for laundromats and other commercial installations. But they do have a few home models.

Oh, they are pricey. More than two and a half times as expensive as the cheapest washer that you can find. Still… based on the reviews I read, I thought that it might be worth the price. When I make a purchase, I either buy cheap (and then I know that I am buying cheap) or buy quality. Now quality is not always available. And often, reputable brand names turn out to be just pretty labels attached to the same cheap, er, excrement that is sold under other names at half the price.

So Sunday, we went to see this washer in person, at a local appliance store that carries the brand. The comparison was convincing. The weight difference alone between the Speed Queen and other washers was revealing. And of course it was a top loader with mechanical controls, a rarity nowadays, but the kind of machine that is precisely my wife’s preference when washing freshly made wool hats, mittens and such in her own special way.

So we opted to buy the Speed Queen, and it was delivered earlier today. Installation was my job. It’s not very hard; you hook up the hot and cold water, install the drain hose, level the machine and power it up. It powered up nicely, and the first test wash went like a charm.

So here we are, with a brand new, yet very conventional, high quality washer installed right next to a 35-year old clothes drier that still works reliably, and now that I cleaned it, looks almost new.

What can I say… apart from the damage to my wallet, it was a fun day. I am glad it happened now, not a few weeks ago when I was struggling to meet some deadlines, having freshly recovered from the flu.

Will this machine last 35 years? Who knows. But I certainly hope that we won’t have to worry about buying another washer for a long time to come.

Oh, and the package contained an interesting surprise: An order sheet for the parts manual and service manual for this model. I think I will buy those. I hope the machine will never need repairs, but if it does and it’s no longer under warranty, maybe I can fix it. Often the hardest bit is knowing what to do, and that’s where a factory service manual can be of immense help.

Here is a short segment from a piece of music that I am trying to identify:

For the life of me, I cannot. It is especially annoying because I heard this piece of music on SiriusXM Symphony Hall earlier this morning, but I didn’t get the title and cannot find a playlist.

This music was played during the end credits of the main evening newscast in the 1960s, perhaps the early 1970s, on Hungary’s state owned television network.

Update (Dec 3, 2017): Mystery solved. It is the Scherzo from Schumann’s 2nd symphony:

The other day, I bought a cantaloupe for my wife.

Today, as she was about to cut it in half, she noticed that it had two sticker labels. Not only that, but held just the right way, the thing looked just like a character from South Park:

Bon appétit.
