The Joys of Infrastructure

cover for How Infrastructure WorksI just finished a wonderful book that explained what it would take for everyone on Earth to live the good life. It was all about infrastructure.

Don’t stop reading! Infrastructure is far from boring, I promise you, especially when the person explaining it to you is Deb Chachra, an engineering professor who both understands how things work and how to explain them. (I’ll just note right here that she has read some science fiction and philosophy along the way.)

The book is called How Infrastructure Works: Inside the Systems that Shape Our World. And no, it’s not a treatise on pipes or wiring or highway construction. It’s an overview of how all those things come together to make modern life possible.

Even if you’ve thought a lot about infrastructure — most of us only think about it when ours fails — this book will give you some deep insights into just how important it is and, even more importantly, how infrastructure design sets in place all our lives.

One of the first things I got from the book is that modern infrastructure is what makes our lives comfortable and possible in the United States and other highly developed countries. We have power at the flick of a switch, water when we turn on a tap, phone service (land lines even still exist, though most of us are using mobile phones these days). The wastewater gets taken away and treated.

Further, we have roads that go everywhere. In some places, we also have other transit options besides cars.

Most of us have access to good food even if we don’t live near where food is grown. That’s due to shipping systems, which also bring us other things we need.

That’s the point: all these things make modern life possible. We don’t have to dig our own wells or fetch water from the nearest creek (if there is one). We don’t have to cut up logs and feed them into a wood burning stove to cook and keep our homes warm. We can be in touch with people all around the world without leaving home or even waiting for the mail (and of course, mail is an infrastructure).

A couple of hundred years ago, people didn’t have most of these things. There were roads and there were shops and some supply systems, but they were not nearly as convenient as they are today.

Despite the fantasy of the “freedom” of living off the grid, the truth is that living in a system with modern infrastructure gives people a great deal more freedom to do something beyond just survival. Continue reading “The Joys of Infrastructure”

Fixing the Air We Breathe Indoors

On May 15, ASHRAE — the association of engineers who work in heating, air conditioning, and ventilation — set out its Proposed Standard 241P, Control of Infectious Aerosols.

They are soliciting comments on it until May 26 from the public. Links and instructions for comments can be found here.

This standard, which was put together over six months — lightning speed for ASHRAE, which often takes years to develop new standards due to its painstaking process — was built on years of work by the organization on indoor air quality and included some input from public health experts.

According to ASHRAE:

The standard will address long-range transmission of infectious aerosols and provides minimum requirements for:

  • Equivalent outdoor air (combined effect of ventilation, filtration, and air cleaning) for use during Infection Risk Mitigation Mode
  • Room air distribution to reduce risk
  • Characterization of filter and air cleaner effectiveness and safety
  • Commissioning, including development and implementation of a Building Readiness Plan
  • System operation in Infection Risk Mitigation Mode during periods of high risk
  • Maintenance tasks and their minimum frequency
  • Residences and health care facilities

ASHRAE issued some recommendations early in the pandemic that provided guidelines for the kind of filtration that should be used in buildings to minimize transmission of airborne viruses. Those guidelines, though very good, were based on ongoing work on indoor air quality and did not include the kind of comprehensive work they brought to this new standard.

These standards, once incorporated into building codes and other regulations for buildings, will be a major step forward in making sure that the indoor air is safe to breathe. In a world in which many people spend most of their time indoors, that is a crucial element of public health.

These standards will minimize the transmission of airborne diseases including, but not limited to, Covid. Continue reading “Fixing the Air We Breathe Indoors”

An Aikido Approach to Chatbots

Tools can be useful,
but don’t count on them to think.
Use them mindfully.

One of the things I’ve noticed is that the discussion of guns for self defense all seem to start — and end — with the purchase of said gun. Perhaps a few of those who hold the view that “an armed society is a polite society” (to quote Robert Heinlein) also advocate serious training, but it’s easy to get the impression that too many people think owning the gun is all you need to protect yourself.

I wrote a story about this called “Survival Skills.” In it an Aikido sensei told the protagonist that no tool is ever ultimately the answer. The protagonist had to learn the core truth of that the hard way, though.

I bring this up because all the furor about the AI chat bots has skipped over analyzing them as a tool that has both benefits and flaws. Some people are already using them to replace humans, without paying any attention to some of their significant flaws. (A writing program that makes up facts and cites non-existent articles is not a tool to rely on.)

And the scammers are already out in full force: people are submitting chatbot written stories to magazines. The biggest problem from the magazine POV is not separating them out from real stories — that’s pretty easy — but the fact they flood the inbox, exhausting the editor who has to deal with them.

Nobody’s going to make any money sending chatbot stories to magazines, but someone’s probably making money teaching people how to do that.

My Aikido teacher used to occasionally say, “I teach philosophy,” meaning that Aikido is so much more than a physical practice. I try to apply the principles of Aikido to other aspects of life.

I just applied two Aikido principles to the discussion of chatbots: relying on a tool when you don’t understand what you’re doing with it and acting without integrity. Aikido teaches you to avoid both of those things. Continue reading “An Aikido Approach to Chatbots”

Asking the Wrong Questions

Maybe when it comes to the chat bots and art bots and other such creations, we’re asking the wrong questions.

I mean, if a chat bot can pass the bar exam, the question shouldn’t be “can a chat bot practice law” but rather “does the bar exam do a good job of determining whether someone would make a good lawyer.”

Having taken a bar exam, I can assure you it’s primarily a hazing ritual. I’m sure the chat bots do very well on the multistate multiple guess portion of the exam, which requires you to memorize vast amounts of information, much of which is not relevant to actual practice.

My experience with bar exams is out of date, but when I took it, we had to learn all the old common law (based on British law) definitions of criminal behavior. These were no longer in use in Texas (where I took the bar) or in any other state that had adopted a modern penal code.

I bet a chat bot is hell on wheels at stuff like that, but I suspect a bot lawyer would not know what to do in a situation where its client was before a judge for revocation of probation (on a felony drug charge) and the judge, in the middle of ranting at its client, gave it a huge wink.

I’m not even sure how a chat bot would know about the wink, but assuming a bot could see it, I suspect it wouldn’t know it was a signal that the judge wasn’t going to revoke probation.

The time it happened to me, I knew what it meant. In fact, I knew from the moment the judge started ranting that he wasn’t going to send my client to prison. He winked at me because I was a young lawyer and he wasn’t sure I understood yet that he was yelling at my client in lieu of revoking probation.

The real practice of law is about subtleties. I suspect algorithm-driven software fueled by large language models is very useful in plowing through reams of documents and will get better, but it’s going to be crap at the negotiating table or in the courtroom where you have to read people as well as put the right information before them at the right time.

Who Counts as a Person?

Back in 2002 I wrote a story about an upper-middle-class young man who got arrested in Louisiana because his physical appearance contradicted his sex genotype: he looked male, but his genotype was XX. He ended up in a jail cell with several transwomen, some drag queens, a lesbian, and a woman who was his opposite: she appeared female but had an XY sex genotype.

This story was set in 2023.

I believed in this story, so I sent it out to every magazine and anthology I could think of. Nobody wanted it. I don’t know why they didn’t like it, but perhaps it was because it seemed too unlikely at the time. Or maybe I was just ahead of the curve in gender stories.

Fast forward to the actual 2023, where Tennessee just adopted a law restricting drag shows and many other states are in the process of following suit. My made-up Louisiana law prohibiting people from dressing or appearing in a way that contradicts their sex genotype no longer looks like science fiction.

It’s almost enough to make me send the story out again, except that these days I bet magazines would turn it down because it’s too much like the real world of today.

Thinking about it reminded me of another story of mine, one I wrote back in the 1990s. It turned on whether clones were people or property under the U.S. Constitution.

That one, called “Passing,” did get published. In fact, it won a contest sponsored by the National Law Journal. Continue reading “Who Counts as a Person?”

What’s New With Voyager 1?

 Voyager 1 is no Longer Sending Home Garbled Data!

This aging and still-valuable spacecraft has been exploring the outer parts of the solar system since its launch in 1977, along with its twin sibling, Voyager 2. They each traveled slightly different trajectories. Both went past Jupiter and Saturn, but Voyager 2 continued on to Uranus and Neptune. They’re both now outside the solar system, sending back data about the regions of space they’re exploring.

Voyager 1 flew past Jupiter in March 1979, and Saturn in November 1980. After its close approaches to those two gas giants, it started a trajectory out of the solar system and entered interstellar space in 2013. That’s when it ceased to detect the solar wind and scientists began to see an increase in particles consistent with those in interstellar space.

These days, Voyager 1 is more than 157.3 astronomical units from Earth and moving out at well over 61,000 km/hour. It’s busy collecting data about the interstellar medium and radiation from distant objects. If all goes well, the spacecraft should continue sending back data for nearly a decade. After that, it should fall silent as it travels beyond the Oort Cloud and out to the stars.

Earlier this year, however, the teams attached to the Voyager 1 mission noticed that the spacecraft was sending weird readouts about its attitude articulation and control system (called AACS, for short). Essentially, the AACS was sending telemetry data all right, but it was routing it to the wrong computer, one that had failed years ago. This corrupted the data, which led to the strangely garbled messages the ground-based crew received.

Once the engineers figured out that the old, dead computer might have been part of the problem, they had a way forward. They simply told the AACS to switch over sending to the correct computer system. The good news was that it didn’t affect science data-gathering and transmission. The best news came this week: team engineers have fixed the issue with the AACS and the data are flowing normally again.

The ongoing issue with AACS didn’t set off any fault protection systems onboard the spacecraft. If it had, Voyager 1 would have gone into “safe mode” while engineers tried to figure out what happened. During the period of garbled signals, AACS continued working, which indicated that the problem was either upstream or downstream of the unit. The fact that data were garbled provided a good clue to related computer issues.

Ways of Making Progress

I am not one of those people who pines for the way things used to be.

I mean, I grew up before there was a vaccine for measles and related diseases, which means that I had every version of measles possible regularly from the time I was five to the time I was ten.

I am fortunate that I had no lasting effects from those bouts, but it wouldn’t have been a bad thing to have missed out on measles.

So I’m a huge fan of vaccines and of other treatments and preventative measures for contagious disease. (I can rant about this at length, and have, but that’s not my goal in this post.)

In general, I’m in favor of many of the changes that have occurred in my lifetime, the mechanical and the digital as well as the medical. For example, as soon as I learned to type, I began writing on a typewriter.

I jumped to correcting typewriters as soon as I could afford one and I got my first computer in 1983 primarily as a writing device.

I also love the communication options. Email is great. Texting is great. Having a phone with you so you can coordinate meeting up in person is fantastic.

What I don’t love are the constant changes and updates. While security updates are important and some changes do provide an improved product, there are way more updates than need to happen.

And of course, if you don’t want to change all those things, sooner or later your computer won’t be able to use the tools it needs.

Here’s the other problem — and it might be the one that bugs me the most — these changes are sent along willy-nilly, with no regard to your reasons for using the device or what you might be doing at the time.

It’s not like you get a message — email would work for this nicely — that says these updates are available and recommended and here is where you go to get them when you’ve set aside some time for tech maintenance. Nor is it like you get a choice when, say, you don’t really want to change your word processing program.

No, they assume that the most important thing in your life is tech maintenance and interrupt whatever you’re doing, when in fact the most important things are the projects that you’re using the tech devices to do.

Writing, analyzing data, meeting people via Zoom — those are the important things, not keeping up the computer. Continue reading “Ways of Making Progress”

Letting Go, Website Edition

I have rituals in the morning. Getting up is hard enough without making a bit of a routine of it. So there is the shower ritual (with various subsets), then the coffee ritual, and then the email-and-internet ritual. The last mostly involves throwing out a virtual ream of political emails and ads, scanning for the one or two emails that actually should get to me (most of them are things like contacts from the doctor or pharmacy–like the olden days of mail, you rarely get something personal that you should actually, like, read). And then I do my morning web-crawl.

This sounds like it should involve a blue-and-red spandex outfit, but sadly it mostly involves me sitting crosslegged on the couch, checking in to the websites I look at every day. Some sites I’ve been checking on for over a decade. Some are newer additions to the crawl. And every now and then I have to pull a site from the rota, and it makes me sad.

When Jay Lake died it took me months to stop checking his page for the roundup of odd and interesting links he posted every day. I mean, I knew Jay was gone, and yet… checking in was part of the ritual. But rather than making it feel that Jay was less gone, it made his loss more felt. Eventually I stopped. Then there are the sites I look at that don’t change every day–Stonekettle Station can go for months without a post (Jim Wright appears to be mostly on Twitter these days) so I’m always taken aback when there’s a new post up. And then there are the formerly active sites that just go silent. I go back and go back and there’s no one there and eventually (like this week) I cut them out of the rota. But not without a feeling of loss.

Since I’m usually doing the blog crawl in between showering and leaving the house for work, having less rather than more material to read is probably a good thing. I have the order in which I check things pretty much reduced to a superstition–I’m not proud of this, but there it is. Which means that not typing in the address of a site that has left the rotation takes thought (at 8am, when I’m still drinking coffee and trying to persuade myself that I can think). My fingers hover over familiar keys and I have to say, aloud, NO, before I go to the next one. I learn, eventually, and the new order of reading becomes second nature–until I have to add something new or, as is more likely, admit that a website that was a source of amusement or information is no longer there. I hold on to things longer than I should, I suppose.

 

 

A Few Thoughts on Technology and Transitions

It’s always amazing and heartening how much inspiration we can draw from the next generation, whether they are our own children or someone else’s. In my personal life, my younger daughter dragged me, kicking and screaming, into the world of social media, into getting my first stupidphone, and later into video chatting (during her  years of medical school on the other side of the country). Now these technologies are part of my everyday and work life. They’ve saved my sanity during the pandemic.

I think it’s good to keep learning new things, to use our minds and bodies in different ways. One of the challenges of these new computer-based technologies is that they require us to use different methods of thought. The transition, for example, from keyboard-based word processing programs (like WordStar for DOS, the one I first used) to graphics-based (Windows) programs entailed a different logic and hand coordination. And both of them are a far cry from the typewriter I used to write my first published stories.

My very first stories (actually, my first umpteen attempts at novels) were written by hand in composition books or on scratch paper. I remember reading an interview with the British mystery writer Dick Francis, in which he described writing in ink in composition books (and that it had never occurred to him that a story, once written, could be revised!) so the method is definitely a time-honored one. Once I learned to type (in high school, on those really heavy manual typewriters) that became my preferred method, although when my children were small, I always carried a spiral-bound notebook on which to work on the Story of the Day in odd moments. Retyping a revision was a major chore, since I had to do it myself. I became expert in the application of white correction fluid. At least carbon copies were no longer necessary, but I had to take my finished manuscript to a copy shop because in those days no one owned a home copier.

I am of several minds about whether the ease of making changes as I go, being able to print out a manuscript at any stage, and so forth, have really changed how I write. I love the saying that the most important word processor is your brain. Perhaps I splat over the page, as it were, more spontaneously when I use a computer just because it’s so easy to tidy up my prose later.

That can be a good thing as I follow whatever wacky idea pops into my mind. Some of them are truly best expunged but others are quite juicy. In some ways I am more focused now than in 30 or 40 years ago; I know much more about how to put a story together, even if it isn’t one I’ve outlined.

Having multiple writing media available to me is a great thing. I often go back and forth when I’m stuck, especially between dictating and typing or typing and longhand. Dictation using voice recognition software is especially great for dialog or speeches (can you see me acting out the parts of the various characters?) Just as we don’t all write in the same way, I don’t write in the same way all the time. Sometimes words flow and then I want the medium that allows me to best keep up with them. But other times I’m stuck (or sulky, or distracted, or tired) and switching can help get things rolling again.

In the end, though, the only version that matters is the one in the hands of the reader.
