Not too long ago (OK, well, 30 years… it doesn’t feel that long anymore) there was another genius on the news: the Genius of the Carpathians, Romanian dictator Nicolae Ceausescu.

Here is a joke from that era that, no doubt, could be adapted to fit the “very stable genius”, too.

The US president, the General Secretary of the Soviet communist party, the Pope and Ceausescu are flying somewhere on a plane. Suddenly, the pilot enters the compartment and says, “Gentleman, I have bad news. This airplane is about to crash and we only have four parachutes.”

Immediately, the US president yells, “I am the leader of the free world, I must survive!”, grabs a parachute and jumps.

He is followed by the Soviet leader, who yells, “I am the leader of the worldwide socialist revolution. I must survive!”, grabs another parachute and jumps.

Next comes Ceausescu: “I am the Genius of the Carpathians! I must survive!”, grabs the next parachute and jumps.

The Pope and the pilot remain. The Pope looks at the pilot and says, “My son, I am old and lived a full life. Your whole life is ahead of you. Please take that parachute. I’ll pray for your survival.” The pilot responds, “No need to worry, Holy Father, we have two parachutes left. The Genius of the Carpathians grabbed the fire extinguisher.”

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.

So our American friends south of the border have a new tax legislation. I’ve seen many discussions of how it affects people in various income brackets, but all too often, these are more confusing than helpful.

So instead, here is a handy chart that shows how the federal tax rate decreases as a percentage of taxable income for individuals, joint filers and heads of households (based on tables provided by CNN):

While most folks will enjoy a tax break, it is interesting to see that some individuals and heads of households will actually see a tax increase:

Married couples benefit the most (mainly as a result of some arcane tax brackets that were in effect before the new legislation), which is probably a Good Thing; I am not so sure about the 2.6% tax break offered to the wealthiest, however.

Anyhow, I pay my taxes in Ontario, Canada, so it really doesn’t bother me one way or another, I just wanted to understand a little better what actually is going on.

Fair warning: This post contains some adult language.

In case there has been any doubt: Republicans have gone completely bonkers, and it is now official.

According to The Washington Post, the Centers for Disease Control and Prevention, America’s leading public health institute, is no longer allowed to use the following terms in its budget documents:

  • vulnerable,
  • entitlement,
  • diversity,
  • transgender,
  • fetus,
  • evidence-based,
  • science-based.

Dear Republicans, dear followers of the orange person in the White House: Are you out of your fucking minds? Have you gone completely bonkers? Truly gone fishing? Are you bat shit crazy? Totally demented?

I mean, what kind of an idiot does this childish shit? You are worse than Soviet political commissars from the Stalin era. OK, you are not sending anyone to the Gulag (yet?) but your retarded drive for ideological purity is like a caricature of itself.

I mean… you are insane. Certifiably. This is not politics anymore. This is not left vs. right, transgender rights vs. traditional families. You are clearly deranged psychopaths.

I am secretly hoping that the news turns out to be false, but despite accusations of “fake news” and the like, I know The Washington Post to be a responsible news organization and I think it is a safe bet that this story was vetted.

The Internet (or at least, certain corners of the Internet where conspiracy theories thrive) is abuzz with speculation that the extrasolar asteroid ‘Oumuamua, best known, apart from its hyperbolic trajectory, for its oddly elongated shape, may be of artificial, extraterrestrial origin.

Some mention the similarity between ‘Oumuamua and Arthur C. Clarke’s extraterrestrial generational ship Rama, forgetting that Rama was a ship 50 kilometers in length, an obviously engineered cylinder, not a rock.

But then… I suddenly remembered that there was another artificial object of extrasolar origin in the science-fiction literature. It is Iilah, from A. E. van Vogt’s 1948 short story Dormant. Iilah is not discovered in orbit; rather, it lays dormant on the ocean floor for millions of years until it is awakened by the feeble radioactivity of isotopes that appear in the ocean as a result of the use and testing of nuclear weapons.

Iilah climbs out of the sea and is thus discovered. It becomes an object of study by a paranoid military, which ultimately decides to destroy it using a nuclear weapon.

Unfortunately, the energy of the explosion achieves the exact opposite: instead of destroying Iilah, it fully awakens it, making it finally remember its original purpose. Iilah then sets itself up for a tremendous explosion that knocks the Earth out of orbit, ultimately causing it to fall into the Sun, turning the Sun into a nova. Why? Because Iilah was programmed to do this. Because “robot atom bombs do not make up their own minds.”

Artist’s impression of ‘Oumuamua

So here is the thing… the Iilah of van Vogt’s story had almost the exact same dimensions (it was about 400 feet in length) and appearance (a rock, like rough granite, with streaks of pink) as ‘Oumuamua.

Go figure.

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.

100 years ago today, as war was raging in Europe, the city of Halifax went up in flames in what remains one of the largest non-nuclear man-made explosions in history.

What began as a series of navigational errors resulted in a collision of two ships in Halifax Harbor, one of which was full of explosives. This ship caught fire and as its crew fled, the burning vessel drifted towards the city. It eventually exploded.

The destroyed Exhibition Building in Halifax, NS, also known as the location where the last body form the explosion was recovered two years later.

By the time it was all over, nearly 2,000 people were dead with many more injured. A large number of people lost their eyesight, as they were watching the harbor from indoors through glass windowpanes. These were shattered by the supersonic shock front of the explosion, the shards turning into shrapnel.

A Mi’kmaq community across the harbor was also destroyed, never to be rebuilt. Many of the residents were killed, while others were housed in segregated shelters, and ultimately dispersed throughout the province.

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.

Recently, I was looking at the registration of sci-hub.io in light of a recent US court decision, and the well-known Russian pirate site hosting illicit copies of millions of scientific papers was still working fine.

Not anymore. That address appears to have been taken down, but an alternative seems to be working fine:

$ nslookup sci-hub.bg
Server: 127.0.0.1
Address: 127.0.0.1#53

** server can't find sci-hub.bg: NXDOMAIN

$ nslookup sci-hub.bz
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
Name: sci-hub.bz
Address: 104.28.21.155
Name: sci-hub.bz
Address: 104.28.20.155

Wonder how long before they take the .bz address down, too.

OK, so today was a Sunday, I have recently finished some projects, so I had a bit of time to work on long overdue things around the house. Actually, it had to do with an attempt to repair an old TV, which needed to be vacuumed first, as it contained more than two decades’ worth of accumulated dust. But quickly, my attention turned to our vacuum cleaner instead.

It is a Kenmore vacuum cleaner, one of the house brands of soon-to-be-defunct Sears Canada. It is reasonably decent. But…

Well, it has a HEPA filter. It is supposed to filter the exhaust of the vacuum, to ensure that it contains no microscopic particles. The HEPA filter is a small rectangular piece made of cardboard and other materials that fits behind a cover on the back of the vacuum. The vacuum was barely a few weeks old when this cover first fell off. Putting it back on didn’t help; it fell off increasingly often. Taping it on didn’t do the trick either. Eventually, I affixed it with two screws, and it seemed to hold afterwards. Even then though, I had a nagging suspicion that there is something odd about this vacuum cleaner…

But first, let me digress. Let me mention a building, a six-story apartment building in the Hungarian city of Pécs, which is the building where my wife grew up. This building is odd, as its stairwell and elevator shaft are housed in an entirely separate building, connected to the main building on each level by a hanging corridor. Rumor has it that the original architect simply forgot to include a stairwell and elevator shaft in the design. Kind of hard to believe but…

Anyhow, back to my vacuum cleaner. My nagging suspicion was this: after the air goes through the HEPA filter, where does it go? It is surely not going to exhaust through the solid plastic filter cover (the one that kept falling off.)

Lately, our vacuum cleaner was making weird noises. When I looked at it more closely today, I noticed that one of the screws that I used to affix the HEPA filter cover was gone, and that the filter cover was slightly off. The weird noise was the air whistling through the resulting gap. Well… this did it. Hard as it is to believe, I was forced to conclude that whoever designed this vacuum cleaner forgot to include an exhaust in the design.

Out came my trusty drill (bought at a Sears store eons ago when Sears was still the best source for quality tools) and a few minutes later, the filter cover had a bunch of holes in it:

I put the cover back on, affixed it with screws again, and tested the vacuum cleaner. It was working just fine, running more smoothly than ever, and significantly cooler to the touch than ever before. And when you put your hands over the holes that I made, you could feel the tremendous outrush of air… air that previously had no place to go other than exhausting through cracks between plastic bits. No wonder the pressure was high enough to push off the HEPA filter cover even when screws were holding it in place.

Before writing this blog entry, just to be sure, I double checked. I don’t want to make a fool of myself after all. But no… there truly is no exhaust, none whatsoever, on this vacuum cleaner.

What engineer in his right mind designs a vacuum cleaner with no exhaust?

Hmmm. Maybe an engineer from the same school that trained the architect who designs buildings without stairwells.

Yesterday, I went grocery shopping.

I came home with groceries and a TV.

You see, Loblaws was selling cheap 32″ smart TVs at the checkout counter. Only 150 dollars (Canadian), and they even paid the sales tax.

We were in need of a TV. The TV that we have in the bedroom (rarely used, but good to have; it’d have been nice earlier this month, when I spent a few extra hours in bed on account of feeling miserably sick) is old, useless and broken. Useless because it’s an analog TV, and there is no analog service anymore, nor do we have an extra settop box for upstairs. And broken because… well, even when it was still actively in use, we needed to whack it every so often, as after it warmed up a little, its picture became elongated and discolored… but a good, well-aimed whack fixed it. Lately though, the picture was permanently distorted and in addition, the TV made a horrible, rattling, buzzing sound (and no, it didn’t come from its speakers.)

Anyhow, we now have a new TV in the bedroom. It picks up OTA digital channels just fine using a small antenna, and it works well with Netflix and YouTube. Perfect. And I managed to haul the old TV downstairs this morning. (It’s incredible just how heavy these larger old CRT televisions are.)

Before throwing it out, I decided to open it up. Who knows, maybe I can fix it and in that case, it can still have a second life at the Salvation Army or whatever. The later it becomes landfill, the better for all of us. So I decided to check this old beast’s innards. Which, in case anyone is wondering, looks like this (yes, I took several pictures just in case I disconnect something that needs to be reconnected the right way):

After removing the back cover and then vacuuming out a few pounds of accumulated dust, I powered it on, listening for the buzz. I also looked at the circuit board using my IR camera. My attention was quickly drawn to the left side, where there are some rather hot parts, but that turned out to be a bit of a red herring: the hottest part is a high-wattage resistor that is meant to shed a lot of heat. Next to it though… what I thought was an inductor turned out to be a relay. And that’s what appears to be rattling!

I checked online. Surprisingly, this is a standard part, not model-specific, still being sold. But the first price I saw was something like $12.50 US plus shipping. Way too much to invest into a 23 year old CRT television set. But then… I found an offer from China for the princely sum of 75 US cents, plus 35 cents shipping. $1.10 in total. Of course I ordered it.

So now I wait. When the part arrives, I’ll attempt surgery. If it fixes the TV, we’ll find a good home for it. If not… landfill, landfill, here we come.

Incidentally, this television set was assembled in Canada. How about that. I don’t think there are many television sets assembled in Canada these days.

I’ve seen several news reports commenting on the fact that Donald Trump was using Twitter while visiting China. That despite the fact that Twitter is one of those Western services that are blocked by China’s “Great Firewall”. Some even speculated that Trump was using a military communications network or some other exotic technology to circumvent Chinese restrictions. (As if the US military was foolish enough to let this idiot of a president’s unsecure smartphone access their network.)

But reality is much more mundane, as I know quite well from personal experience in China.

When you are traveling with a phone registered to a foreign service provider, your Internet connection initiates from that provider’s network. So insofar as the Internet is concerned, you are not even in China. Your connection initiates from your home country. In my case, whenever I used my phone in China for Internet access, I accessed the Internet from an IP address registered with my Canadian cellular service provider, Rogers. I had unrestricted access to Google, Facebook, CNN and other news sites, with no Chinese restrictions.

Trump probably did exactly what I did, except that he probably worried about international data roaming charges and data caps a little less than I. He grabbed his phone, turned it on, and used it without a second thought. (OK, that’s not exactly like me. Trump was probably not surprised to see Twitter work on his phone in China, because he probably knows very little about the Great Firewall. I was mildly surprised myself, especially as I went there prepared for the worst, with multiple overt and covert VPN options prepared just in case I needed them. Which I did… but only when I was using the hotel Wi-Fi instead of the cellular network.)
