body cams

I just finished up my third Philadelphia jury experience. I’m not going to give any details of names or locations, but one thing that struck me was the role of technology. This trial featured:

  • Instagram
  • Someone (allegedly) impersonating a delivery person
  • Selfies, which ended up in court
  • A (temporarily) purloined cell phone
  • Police body cam videos

Now, about those police body cams. We started hearing about them in the context of police shootings of suspects, but after seeing them in court I realized that they change everything. First, there is a world of difference between hearing the testimony of a police office about what happened on the scene, and seeing and hearing (although the audio was not perfect) it for yourself. For one thing, police are not masters of public speaking. For another, the incident they are describing happened months or even years before, and was just a few short minutes during one busy day. They may have responded to hundreds or thousands of similar calls since then. The body cam footage will even help the police officers themselves remember what happened on the scene before they testify.

Wired on the technology of 2021

The Wired Gadget Lab podcast asked what the important (consumer) technologies of 2021 were, and came up with cloud gaming, e-scooters, Peloton, and “unplugging from the internet”. Someone also mentioned the Covid-19 vaccine, which I would tend to agree with.

On cloud gaming, I am looking forward to getting back into video games (I’m middle aged and still call them that) when and if my intensive child rearing years start to slowly and gradually wind down. I used to be a fan of “real time strategy” games, and just assumed I had missed a lot of awesome ones over the last decade or so. But according to another Wired article that is not the case, as the genre has been overshadowed by other, more profitable types of games. Hopefully they will come back, because I think lots of people like them. I can also imagine hybrid games where you take direct a large-scale, long-term strategy but get to zoom in and take part in a battle or other short-term simulation when you want. Sure, this would take a lot of programming and computing power, but the technology is getting there right?

I’ve hit the Wired paywall. I like Wired, but I just can’t subscribe to everything piecemeal and have 99 little charges on my credit card each month that add up to all my money. Can somebody come up with some sort of clever cross-platform discounted bundling service for magazines, newspapers, apps, games and other subscriptions?

Okay, on e-scooters, my position is they are a menace on the sidewalk and have no place on the street. I don’t think I am turning into a grumpy old man – what I mean is our streets and sidewalks are designed with no safe place for them, except where we have safe, well-designed “bike lanes” and signals, which is almost nowhere in the United States. They’re a menace to themselves in the main travel lanes, and people zipping around on fast battery-powered devices have become pretty threatening to pedestrians on our narrow sidewalks. I am not particularly excited about getting an e-scooter, but if their proliferation means we get more safe protected lanes for bikes and scooters, I am all for them. If we get to a place where maybe one in ten people traveling from point A to point B in a city is inside a one-ton steel killing machine, but they are still taking up 90% of the space and killing our children, will our ignorant, cynical politicians and bureaucrats give us safe streets? I will try to be optimistic.

On Peloton, it looks fairly neat. I’d still prefer to exercise outside, but maybe one day I’ll give it a try, or if someone else in the house were to express an interest that might tip the scales in its favor.

I’m trying to think of a technology that changed my life in 2021. When the Apple podcast app glitched out on me after an update, I switched to Overcast and haven’t looked back. I wouldn’t call that life changing. I love my Audible audiobooks and my Kindle from 2013 that is still working just fine. I am still totally addicted to RSS feeds – Feedly is still my go-to app and I hope it and the feeds never go away (they are, though, one by one). I’m been using Microsoft OneNote for years at work. In 2021 I figured out there is a magic button that generates a meeting note template for any Microsoft Outlook meeting, with the date, subject, attendees, etc. all pre-populated. I started using OneNote for personal notes before 2021, but in 2021 I found myself using it more and more and using it across platforms. It all syncs pretty well, and being a helplessly compulsive list maker all my life I love being able to jot down a note anywhere, anytime. I use Philadelphia’s public bike share system, Indego, which works pretty well except a month or so ago I misplaced by bike helmet and haven’t gotten around to replacing it (I’ve dropped a hint with family members I hope have a line to Santa). I use a number of fitness and health tracking apps – including but not necessarily limited to Apple Health (for tracking steps and weight), Virgin Pulse (required by my employer, not necessarily recommended), LoseIt (for calorie counting), MyLimit (for blood alcohol, which to be clear is 0 most of the time but it’s interesting and useful to understand how alcohol affects the mind and body), and MyChart (for medical records). Each of these has a reason behind it, but taken together they are too much. For the month of December, I have decided to just try to maintain healthy habits but not actually track anything. I’d like to find more automated ways of collecting data on these things and reviewing it occasionally so I can consider some healthy adjustments, without opening half a dozen apps and typing things into them every day. And finally, I bought something dumb, expensive and fun called Twinkly, which is an app-controlled string of LED lights.

UFOs getting harder to ignore

There are more videos coming from the military, and they are getting harder not to take seriously. Apparently, the military looks at these videos pretty closely and if they thought it was a drone or a balloon of some sort, they would call it that. If they can’t explain the technology that would produce the behavior observed, it becomes an “unidentified aerial phenomenon”.

why people don’t smile in old photos

I always wondered this. I think the first black and white photos I ever saw were from the Depression era, and I just assumed people were…depressed. But I noticed later that a frown is typical of most old photos. I’ve also noticed that this is not just an American thing, but true of other cultures. When people would show me pictures of their grandparents, they would have a stern expression, and pictures of their grandchildren at the same age would be all smiles. You even see pictures of families together where the grandparents look pretty fierce and everyone else is smiling.

This video says that early on people treated a photo as though it were a portrait being painted. It was a rare thing that might only happen once and was expensive. There would just be this one picture for people to remember you by. There was also the practical matter that early on, you had to sit still for 10-15 minutes and it was hard to hold a smile that long. The video also talks about the practice of taking pictures of the dead, including children, which I found sad but it makes a certain sense. In some cases that might have been the only photo taken of the person.

measuring blood pressure through your @$$

This seems like a good idea actually – a toilet seat that measures your heart rate, blood pressure, and oxygen level. It’s designed for hospitals, but it makes a lot of sense to me. It would happen automatically, built automatically into your daily routine and with no wasted time or extra effort. You could have it sent right to your doctor if you wanted to.

new technology that can screen multiple passengers 25 feet away

Here’s some more information on new airport screening tech (LA Times).

The screening device, which is about the size of an old-fashioned PC computer tower and weighs about 50 pounds, reads the outline of people to reveal firearms and explosives hidden under their clothes.

Unlike the TSA’s existing full-body scanners that bounce millimeter waves off of passengers to spot objects hidden under their clothes, Gramer said, the passive terahertz technology reads the energy emitted by a person, similar to thermal imaging used in night-vision goggles…

As a result, Thruvision boasts that its technology can screen up to 2,000 people an hour and detect a concealed device at a distance of up to 25 feet. Initially, the system can be used in addition to the existing full-body scanners already deployed at airports, but Gramer said the device can eventually replace parts of the TSA’s security screening system.

I think anyone will welcome a more convenient flying experience at this point, but it is somewhat sinister to think of this technology being installed in all sorts of public places, work places, police cars, etc.

Swedes getting chippy

According to NPR, people in Sweden are voluntarily inserting microchips into their fingers and using them for identification and payment.

The chips are designed to speed up users’ daily routines and make their lives more convenient — accessing their homes, offices and gyms is as easy as swiping their hands against digital readers.

They also can be used to store emergency contact details, social media profiles or e-tickets for events and rail journeys within Sweden…

Around the size of a grain of rice, the chips typically are inserted into the skin just above each user’s thumb, using a syringe similar to that used for giving vaccinations. The procedure costs about $180.

There are also some interesting statistics on the declining use of cash in Sweden. The article says that in Stockholm only 1 in 4 people uses cash once a week (or more) and only 15 percent of retail transactions involve cash (and this was already down to less than half as of 2010).

what’s up with solar roadways

This article from “The Conversation” surveys a number of solar road installations around the world. It is pretty down on them, saying they are less efficient and less cost-effective than solar panels on solar farms or rooftops. Okay, but it never says they make bad roads. So where this has been tried, you have functioning roads that didn’t generate electricity before and now do. Most technologies have a tendency to improve and come down in cost over time, so the fact that these pilot projects are up and running and generating power without major mishap doesn’t seem to me like a reason to give up on the idea.

long-term energy storage

Vox talks about long-term energy storage, which could theoretically smooth out energy supply and demand fluctuations over periods of days or months rather than hours as today’s batteries do. Some of the ideas include thermal storage, flow batteries, electrolysis combined with fuel cells, and pumping water underground at high pressure.

forestry robot

Here’s a robot that can help forestry scientists collect data in the field.

Mikhailov is a 16-year-old student atITMO University, the renowned science and technology institution in St. Petersburg, Russia. As a member of the school’s Youth Robotics Lab, he was perfectly positioned to bring his idea to life. With a full team working on the the project, the robot won the gold medal at last year’s World Robot Olympiad; it can record tree locations within a forest, identify their species, measure the widths of their trunks, and even identify if a tree is healthy or not.

Its name is Forester, and most of its job is to explore forests and hit trees with its mallet. It’s a robotic adaptation of a technique that human tree experts often use, called “sounding,” to help their appraisal of a tree’s health.
