Today I realized that in the past month, my blog has once again become what blogs were meant to be originally: a write-only medium that nobody reads.

Well, almost. The few people who actually bother to look it up at spinor.info could still read it (and thank you for your interest!) The few people who follow my tweets may have seen my posts. People on Google+ may have seen them as well, but are there still people on Google+?

However, the WordPress plugin that I’ve been using for the last couple of years now to publish my posts automatically on my Facebook page has quit on me. And since I was not usually checking my own Facebook posts, I didn’t even notice that something was amiss, I merely assumed that my Facebook friends were really not that interested in what I had to say.

In reality, my posts never made it to Facebook. The culprit has been one of the stupid “migrations” of the Facebook API (Application Programming Interface), which I foolishly enabled, thus breaking the plugin.

Anyhow, thanks to a helpful hint by the plugin’s developer in a WordPress support forum, I was able to find the cause and fix the problem.

I have yet to figure out why people who develop software on which other people depend, most notably people who develop software libraries that are used by other people’s programs, are so keen on making changes that seemingly serve no useful purpose other than breaking said other people’s programs.

Grumble.

This beautiful cat belonged to my mother-in-law. I last saw him just a few short weeks ago, when I visited her in the city of Pécs, Hungary.

Sadly, my use of the past tense is justified, as Frici (which was his name) is no more. He passed away today, from what appeared to be a severe urinary tract issue, I was told. He was only about four years old. He was a stray that ended up with my mother-in-law after she lost her previous cat.

Yes, we know that it’s just a cat. Yes, we know that cats who spent some time on the street as strays like Frici are much more likely to acquire an infection, or just suffer the consequences of prolonged malnutrition or dehydration that would eventually shorten their lives. Still… Frici was much too young to pass away, and did not deserve to pass away in pain.

Life, I guess. Cherish every day of it, who knows how many are left.

This morning, my wife and I attended a very moving ceremony in the memory of my good friend, George Olah, who passed away earlier this year.

George’s daughters decided to dedicate a tree in a public park in Ottawa to their father. A little marble plaque at the foot of the tree bears George’s name, the dates of his birth and death, and the Hungarian word for cheers, “egészségedre”.

A violinist was also present. The sound of a solo violin during a cloudy, rainy day was especially poignant and it helped set a somber mood. At one point, when the violinist was asked to play one of George’s favorite tunes, I was able to capture a few seconds of it with my cell phone.

Yet we also had plenty of laughs. George, after all, was a very happy person and his stories were always delightful. My favorite moment: when one of George’s daughters told us that the city permit would even have allowed them to set up a trampoline, several of us exclaimed, “Why didn’t you?” That is because we all knew that George would have loved something so unconventional.

I noticed that the pictures on Google Street View for our neighborhood were updated recently. Much to my delight, I noticed that two cats from the neighborhood, cats that we have known for at least seven years, were photographed by Google’s cameras:

Yes, my wife and I are both fond of cats. Not just our own four cats but also cats from the neighborhood.

Today, the weirdest thing happened on my main desktop computer: the right-click menu of Windows Explorer, as well as the Windows desktop, disappeared. I was also unable to bring up the Properties dialog, even through the menu bar.

The worst part of it is, I could not figure out what happened. A reboot didn’t fix things, nor did an obvious Registry hack (making sure that HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoViewContextMenu is set to 0. For some reason, it was set to 1.) Eventually, I resorted to the big guns and used System Restore (thanks to the fact that I do backups daily, I had a restore point from 2AM this morning) to fix things. Still, it bugs me that something happened that I do not understand.

In comparison with another, mostly identical system, I noted that the other system had no subkeys under the Policies key whatsoever. So I wonder exactly when and how the Explorer and System subkeys were created on this workstation.

And while I was at it, I searched the Registry a little more and found another, possibly relevant entry: HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoViewContextMenu. Once again, this Registry value is missing from the other machine, so I wonder how, why and when it was created on this workstation.

This is deeply disturbing. I don’t like mysteries, especially not on a machine that I use on a daily basis. Life is short and one does not need to resolve every mystery, but occasionally, such unexpected behavior can be a sign of a security issue.

There was another reason for me to stop by in London: the possibility of meeting some old high school friends, celebrating a shared milestone in our lives as we are all turning 50 this year.

The reunion was smaller than we hoped for, as in the end, only three of us were present. But the evening went well, good food, good beer, good company and all. One of my friends was, in fact, just recently in North Korea, and the stories he shared were absolutely fascinating.

When I decided to visit London, I secretly hoped that if I am lucky, I’d spot the TARDIS, Dr. Who’s infamous “bigger on the inside than on the outside” time machine.

Thanks to Richard Bartle, my quest was not in vain. The TARDIS, as it turns out, is sitting quietly just outside one of the exits of the Earl’s Court Underground station.

Except that…  well, it’s not the real TARDIS. Instead, it’s just an ordinary blue police box, just like the one the TARDIS mimics, but unlike the TARDIS, this one is decidedly not bigger on the inside than on the outside. Still, it was fun to find.

With four cats in our house, it’s easy to guess that my wife and I are both animal lovers. To be sure, we are partial to felines, but we love most other animals (with obvious exceptions such as flies or mosquitoes) and we are especially troubled when we see animal suffering.

And animals suffer a lot. Especially in wars. Which is why I find the Animals in War Memorial especially poignant.

I happened upon this memorial when I made an unplanned detour on my way to Leicester Square, where I was to meet with Richard Bartle, who was kind enough to come to London to see me. We were supposed to meet under the Shakespeare statue at Leicester Square. When I arrived, there was no Shakespeare statue. Fortunately, I eventually realized that the cordoned off area in the center of the square does, in fact, hide the statue which is currently being renovated. Shortly thereafter, I spotted Richard.

I was silent in the past ten days because I was traveling. I spent six days in Hungary, and a few more in London, England.

I’d like to say that I had a blast of a time but that is not strictly true: I had a rather nasty bout with gastroenteritis that severely interfered with my plans concerning my time in Hungary. Indeed, let this serve as my apology to all those friends I did not have time to look up: the two days I reserved for this purpose, I ended up spending mostly in my hotel bathroom. Oh well.

At least the view I had from my hotel room was enjoyable. I don’t mind trainspotting, and I was on a high enough floor that the noise was negligible, even with the window open.

The view from my London hotel room was perhaps a little less exciting. But, at least it was also a quiet room. Or would have been, were it not for some noisy neighbors next door. (Yes, dear lady, the entire floor heard you when you were loudly banging on your friend’s door at 6 AM yelling, “are you awake?” We all were, by then.)

If only my room had been a tad bigger, with a mattress a tad less worn and a TV mount a tad less broken, I’d have been entirely satisfied. But beggars can’t be choosers, and when looking for reasonably priced accommodation near Paddington station in London, we are all beggars.

And the weather in London was absolutely spectacular. Blue skies and sunshine most of the time, not too warm, with a pleasant breeze.

Now I am safely back home, though still nursing my left foot; I almost twisted my ankle getting out of a car about a week ago in Budapest, and endless walks in London did not help either. Hopefully, I’ll stop limping in a day or two.

In all the excitement (okay, I wasn’t that excited. But, I was busy) I almost forgot to celebrate an anniversary: it was 40 years ago on April 5 that Pioneer 11 was launched at Cape Canaveral.

In a recent Letter to the Editor published in the newsletter of the American Physical Society, a correspondent suggested that Pioneer 11 may still reveal some anomalous behavior. I do not believe this to be the case. While it is true that our investigation of Pioneer 11 was not as thorough as our investigation of Pioneer 10 (due, in part, to the fact that we have less Doppler data from Pioneer 11) there are no statistically significant inconsistencies.

This Letter also reveals two misconceptions about the anomaly. One is that if the anomaly is Earth directed, which would presumably be inconsistent with a thermal cause. This is not so: quite the contrary, since the spin axis and the Earth direction mostly coincide, an Earth directed anomaly is exactly what one would expect to see in case of a thermal cause. Second, I don’t think it is even relevant to say that “a new physics cause may still be possible”. Of course new physics is always possible. But before one can speculate about new physics, “old physics” must be excluded, i.e., there must be an incontrovertible demonstration that conventional physics cannot account for the observed phenomena. This is not the case for the Pioneer anomaly: conventional physics comfortably accounts for the anomalous acceleration. Sure, there are small discrepancies that are within the margin of error, but you don’t fish for new physics within the margine of error. That’s not the way science is supposed to work.

A few moments ago, my wife looked up through our skylight and lo and behold, saw a moving star.

Not just any moving star; it turned out to be the International Space Station, in all its still sunlit glory over the late evening Ottawa sky.

I once managed to capture the ISS through my cellphone; the picture turned out to be surprisingly good, even showing (I think) the somewhat rectangular shape of the station.

Anyhow, I hope Chris Hadfield is having a great time up there.

Here is a beautiful military relic, a gift from a family friend who knew that I was a sucker for old technology:

It is a very conventional compass, floating in oil in a non-magnetic brass casing. Our friend was concerned about the radiation symbol on the cover: as it turns out, this particular compass had fluorescent markings that were illuminated by the presence of small amounts of radioactive tritium.

As tritium is a low-energy beta emitter, it poses almost no health risk (unless you happen to inhale or consume some quantities of it) and thus it is safe for use as a form of “permanent illumination”. Unfortunately, tritium is also used in thermonuclear weapons, so its possession and sale are often regulated. In any case, this old compass is long past its “use before” date; I don’t know how old it actually is, but its inspection sticker dates back from 1994. The tritium appears to be long gone (not exactly a surprise, given tritium’s relatively short, 12.3 year half life), as the marking are completely dark.

Still it is a beautiful device, and I am very grateful to our friend for offering this to me as a gift. It will be cherished.

After another 550 km drive at the end of an already very long day, I finally made it home late last night, concluding a very productive 3-day visit at the Perimeter Institute.

While there, I gave another talk on the Pioneer anomaly. I felt that it went well and as far as I can tell, it was very well received.

All in all, it was time well spent.

Here is one of our four cats, Kifli. (Literally, his name means croissant in Hungarian. How did he get this name, you ask? Well, when we got him back in 2001, he was only a few weeks old and he and his brother Szürke actually fit on the palm of my hand, both of them together. Szürke is a gray tabby and perhaps somewhat unimaginatively, that’s exactly what his name means in Hungarian; gray, that is. Kifli has the color of a freshly baked bun, but when he was little, Kifli was very thin and did not look like a bun at all. In Hungarian bakeries, the two most common small bakery products are buns and croissants; not the puffy French type made from leavened dough, but croissants baked from the same dough that is used to make white bread and, well, buns. These croissants are long and thin, just like Kifli. Hence, his name.)

Anyhow, I was testing out an Android photo editing app (PicsArt, in case you’re wondering; seems like an excellent app, by the way) tonight when I snapped this picture of Kifli and applied one of the app’s effects. I think it’s real nice. And while it’s not so nice that Kifli jumped onto a table that he’s not supposed to be on, I certainly approve of his reading choices.

I thought my server would break some record in the coming months, perhaps running up to two years without a restart.

Alas, that will not happen: we received notice from Ottawa Hydro that they will be doing maintenance tomorrow morning and our power will be shut off for a while. The duration (3.5 hours) is way more than what my server’s UPS can handle.

Oh well. It was nice while it lasted:

Here are a few things I am not planning to do today:

  • I will not feel particularly sorry for myself.
  • I am not buying a red Porsche. (I always preferred muscle cars over European toys anyway.)
  • I am not going out to find an expensive girlfriend.
  • I will not run away from home with a girlfriend half my age.
  • I am not planning to have a heart attack (of course, one never knows.)
  • I will not to start hair replacement therapy (and not just because I don’t need to.)
  • I am not going to complain (too much) about my back hurting.

Last but not least: I am not going to grow up. According to an Internet meme I just came across, if you haven’t grown up by age 50, you don’t have to.

I am getting close to breaking some of my records here. My main server has now been up 70 days longer than the planned trip to Mars:

There really was no need to reboot, and there won’t be any unless a) there is a critical patch to this version of the Linux kernel, b) I decide to carry out a planned upgrade to Slackware 14.0, c) the system crashes, d) the hardware fails, or perhaps most likely: e) I decide to bring down the server in order to remove a few pounds of cat hair, dust bunnies and whatever else may have accumulated in its case over the course of 19 months.

Two days ago, I received the sad news: my good friend George Olah is no longer among us.

I actually have a recent picture of him, courtesy of CBC Ottawa: during a news report last year about smoking prevention, George appeared in a bit of stock footage, standing on a sidewalk somewhere in downtown Ottawa, smoking a cigarette.

Yes, George was a smoker, which may have had something to do with the sudden heart attack that took him from us. Or not. Sometimes, perfectly healthy people with no ill habits die for no reason at all.

George fled Hungary in 1956 after the failed anti-communist revolution and eventually came to Canada. Yet his opinions were never clouded or biased by his personal experiences: he had a sober view of the current political situation in Hungary, and shared many of the concerns my wife and I have regarding the country’s future.

I’ve known George for nearly 26 years. Back in 1987, when I came to Canada, it was George who introduced me at the company where I got my first consulting contract. Thanks to George, I never had to wash dishes or fry hamburgers; within a few weeks of my arrival, I was writing C code for an application at Forestry Canada. A few years later, when I was going through a difficult time, it was again George who got me in touch with a group that hired me for a programming job; the people I worked with there remain my friends to this day.

In recent years, George was busy with a number of interesting projects that involved low power wireless technology and ad-hoc networking. He had high hopes for his inventions. Indeed, he was a true optimist, always full of plans for the future. You couldn’t really tell that he was already past his 70th birthday.

George also liked to cook. Around Christmas, he often made cabbage rolls in quantities that would feed a small army. This past Christmas was no different; and not for the first time, he offered us some, which I duly picked up at his home. It was very tasty. Yum! We have not yet returned the container.

Well, I guess that was the last batch of cabbage rolls George ever cooked. And the aspic jelly, another one of George’s wintertime favorites that he was planning to prepare, won’t be made either.

What else can I say? Thank you, George, for the help, for the memories, for the food, for all the laughs and for all the fun. Szervusz, Gyuri.
