The problems with self-driving cars

Self-driving cars, like the AI technology they are based on, seem always to be just tantalizingly beyond our reach at any given time. I have been hoping that self-driving cars become a reality because I am getting on in years and there is bound to come a time when it will not be safe for me to operate a vehicle, even though I have been accident and ticket-free my entire driving career, except for one fender-bender and one minor infraction, both of which took place over three decades ago when I was young, wild, and foolish. (No, not really. Both were rather boring events.)

The loss of driving privileges can result in a deep drop in a person’s independence, especially in the US which has pretty bad public transportation services. Having a self-driving car would provide older people or those with any issue that prevents them from driving, from being housebound. Of course, these cars are initially likely to be expensive but over time the prices should come down. The catch is that even though these cars have improved tremendously, they still seem to be not ready for prime time.

Does online advertising work?

As someone who spends way more time on my computer than is probably healthy, I am familiar with online ads because they bombard me all the time. We know that online advertising has been a huge wealth generator for those companies such as Google and Facebook that sell and place ad space and indeed is the source of revenue for any ‘free’ content on the internet. (This blog is the exception. It is genuinely free!)

The promise that the media platforms offer to ad buyers is that they can target the product to the individual buyer who may be looking for that particular item, thus preventing wasteful blanket ads. The way the platforms do that is by vacuuming up all the information they can glean from us from our online activity to create a detailed profile of each one of us that they can then sell to retailers, a process known as ‘microtargeting’. This promise of ultra-efficiency is what has led the migration of ads from print media to online media. It has also led to fears that that we are now living in a Big Brother world because our lives have become transparent to these big companies like Google and Facebook who seek every way of prying into our lives.

Webb telescope instrument alignment completed

The last major step in the development of the Webb space telescope, checking the alignment of all the instruments, has been successfully completed and all the instruments seem to be at the correct operating temperature. NASA has released images taken of the Large Magellanic Cloud to show the clarity obtained.

The image shows snapshots from each of Webb’s three imaging instruments, plus its spectrograph and guidance sensor. The images show a field of stars in the Large Magellanic Cloud (LMC), a galaxy near the Milky Way about 158,000 light-years away. If it orbits our galaxy, it would be, by far, the largest satellite galaxy. But there’s a chance it’s just passing through or slowly merging with our galaxy.
…

Now that the imaging instruments are properly aligned, NASA and its partners will begin commissioning several science instruments. These are components within the imaging instruments that can do things like filter certain kinds of light, adjust the cameras to specific customizations, or apply a particular lens. That could take a few months, as could a few calibrations to confirm that the telescope is temperature-stable when it moves between targets. During that time, mission control will also monitor mirror alignment to make sure it stays in place.

NASA has also released a video of the event.

In a few months we should start receiving images of parts of the universe we have never seen before.

Lethal fruit

Donald Trump has been sued (again!) for inciting violence by urging his bodyguards and his supporters to physically attack critics and protestors at events that he attends. As part of the case, he had to submit to a legal deposition towards the end of last year and in the course of it, he expressed fears about reports that he might be pelted with fruit, especially tomatoes.

The Daily Show‘s Trevor Noah say that no comedy writer could match the quality of the humor in the deposition transcript and to prove it he and Michael Kosta read verbatim from the it. That five-minute segment begins at the 5:45 mark.

Tomorrow begins my month!

My calendar software informs me about holidays and such and today it said that May 1 is the “First Day of Asian Pacific American Heritage Month”. I had no idea.

I am not sure what to do with this new knowledge. Perhaps I’ll order some takeout Chinese food to show solidarity with my fellow Asian Pacific heritagers.

It is strange how May 1, which has been celebrated all over the world since 1889 as a day of worker solidarity known as May Day or International Workers Day, is completely ignored in the US even though its origins lie in this country. But as a result of anti-communist fervor, the labor movement in the US distanced itself from it and shifted it to Labor Day in September, which itself has become a pretty ordinary holiday, shorn of any labor militancy.

Authoritarian delusions

What is happening in Sri Lanka is an example of how authoritarian leaders will cling on to power by trying to give the impression that they still have the support of most of the people. In this case, the current president Gotabaya Rajapaksa was easily voted into office on the strength of his reputation as a ‘strong man’. This was because as defense minister when his brother was president, he unleashed the military in an extremely brutal crackdown on the separatist movement of an ethnic Tami minority. That elimination of the separatist threat made him a hero in the eyes of the Sinhala Buddhist majority, especially since the victims of that assault were largely Tamils. Then in April 2019, a terrorist cell of suicide bombers exploded bombs in eight locations including three luxury hotels and three Catholic churches, an act of senseless violence that saw large numbers of casualties.

Another cryptic WhatsApp text

I wrote recently about these random WhatsApp text messages that I occasionally get from unknown young women. Presumably, they are the first stages of a scam that will reveal itself if I reply, which of course I never do.

But I am interested in the logic by which they hope to ensnare me and the latest leaves me completely baffled. It reads in its entirety:

“Uncle Ryan will send you to pick me up at the airport next month in a rolls Royce. I’m going back to Ohio soon.”

First off, unlike the earlier ones, this one is oddly specific, mentioning Uncle Ryan, a rolls (sic) Royce, and Ohio. The only part of it that has any connection to me is Ohio.

Also, why does Uncle Ryan need me to pick you up? Why can’t he do it himself or assign the task to the driver of the car? I am a busy person, and cannot drop everything just to go to the airport for no reason.

New trial for Melissa Lucio

I have been highlighting the potential for a gross miscarriage of justice that was due to occur today in Texas when Melissa Lucio was to be executed for the murder of her two-year old child despite the increasing evidence that she might be innocent and the appalling way that she was interrogated, using many standard coercive methods, that resulted in a confession. The potential for a massive injustice was so great that state Republican lawmakers, even those who support the death penalty, joined in a bipartisan effort to have her case reviewed. Five members of the original jury that convicted her said that if they had been told the full story, they would not have voted to convict.

Yesterday, a state appeals court stayed the execution and sent her case back to a lower court to take into account new evidence.

Great moments in truck protests

Things have not been going well for the grandiosely titled ‘People’s Convoy’ of trucks that was supposed to bring life to a halt in the nation’s capital. They first drove all across the country to Washington DC to protest vaccine mandates or something and then hung around for a week or so at an abandoned racetrack about 50 miles north of the city. After that non-event, some of them then returned to California and decided to protest near the Oakland home of a California state assemblywoman.

But they got a hostile reception from the neighbors who were incensed at big trucks clogging up their quiet and narrow residential streets with their loud air horns blaring and told the truckers to get the hell out of there. As the trucks were leaving, they got stuck in traffic near a Safeway grocery store and a large number of people, many of them young, started purchasing eggs from the store and pelting the trucks, forcing them to flee.
