Monday Mindset: Help and hindrance, standards

At one time I read product standards as a full-time job. I left that job years ago but I still look at what standards a product says they comply with, or are expected to comply with.

Simplistic description of standards.

Many standards do serve a useful purpose: they set expectations for a product. Depending on the standard and who issued the standard, those expectations might cover safety, features, performance, reliability, or other things.

Some standards are free, some cost a bit to purchase, some cost hundreds of dollars to purchase. Some are fairly straightforward to read, some are very dense. The trickiest seem straightforward when reading them, except there are certain terms which have a specific meaning in the industry or market covered by that standard, and that meaning isn’t well known to people outside that industry or market.

Standards can become a hindrance when the market expects or insists a product has to meet a certain standard. A person might have a good product idea but find themselves in an industry or market where the required standard is very expensive to buy or very expensive to comply with.

Standards are by definition reactive and a reflection of the past. Standards describe what has already been made and how it should be made going forward. I don’t know of any standard which was written about an imaginary product, in the hopes someone would read the standard and create a product to meet that expectation.

Standards are a really good way to show the limitations of language in describing the world.

Standards are initially written with an ideal something-or-other in mind. As time goes by, there are revisions which are almost organic in growth. These revisions usually come from someone trying something which didn’t work, or didn’t work as expected.

If a standard is written very precisely and explicitly, it’s easy for someone to avoid if they want to: find a way to describe their product which is different than that precise definition. Then the standard doesn’t apply. And if the definition is written more broadly, then someone who wants to avoid it can argue about the meaning of the words or the intent of the writers. And the standard still might not apply.

Any product or facility which was built or designed more than five years ago, and is being held to a standard whose initial edition was written more than five years ago, will have at least one place where the language or practices have shifted and it’s possible someone could claim the standard possibly wasn’t being met.

The best way to I found to learn a standard is to write a summary of each clause. That’s also very painful and arduous.

Why am I talking about all of this?

I don’t get to turn my brain off because somewhere a product standard got mentioned. I don’t get to turn my brain off because a product says they comply with a certain standard. And I don’t get to turn my brain off because a product doesn’t say it complies with a certain standard.

Standards can be helpful. Like any other tool, they can also be a hindrance.

Technician Tuesday: Some of the measurements for light

The human eye has a huge dynamic range for the amount of light our eyes can use. We can read in bright sunlight and most of us can read by candlelight. Yet the difference in the amount of light from those two source is almost ludicrous.

Trying to decide what light source to use by looking at specifications, instead of repeatedly buying-and-trying, is also almost ludicrous. There are multiple measurements used. The measurements don’t always measure the same things.

The best description I’ve seen recently is in the article “Lumens, Candela, & Lux” by Richard Nance, in the January 2023 issue of Guns & Ammo magazine.

(No, I still have not looked up how I should be citing my sources.)

For the terms lumens, candela, and lux,

  • lumens is how much light comes from a source,
  • candela is the intensity of the light in a chosen direction, and
  • lux is the amount of light on a surface when it’s a specific distance from the light source.

If I’m buying a light for my desk or nightstand, I’ll probably start looking for a lux specification. For portable lights like flashlights or worklights, I’ll look at both lumens and candela to see how much light there (theoretically) is and how focused that light should be. A small focused beam of light is great when I want to see tiny detail. A wider beam is better if I want a more panoramic view, such as if the power goes out and I want to see the entire room well enough to not run into the nearest table.

Light temperature is an entirely different topic.

And then . . . ugh. The article mentioned there was a flashlight standard, ANSI NEMA FL 1. I thought that would interesting to look at. And it was interesting, in a way that’s mildly frustrating and not at all what I expected. I’ll make that a part 2. There might be a part 3 where I post some good links I found about the flashlight standard which don’t cost at least five hundred dollars to view.

Mindset Monday: The tool is not the skill.

Way back at the beginning of this blog, I wrote about the importance of knowing what I want to achieve when I start working with a piece of technology. That post was about the importance of knowing my goal and motive.

My post today is the importance of not confusing the tool with the skill. There are lots of drawing and art software programs available, but none of them make me a good artist when I buy them. There are lots of software programs for music and sound available, but none of them make me a good musician, composer, or sound technician just because I bought them.

Becoming good at a skill takes a lot of work. It takes practice, and research, and looking at other examples in that same field, and more practice, and more research. It’s a slow process. I have to put in the work. I can’t trade money for the software program or electronic gizmo or whatever and have that also be a trade of money for time and effort. The tool is not the skill.

Mindset Monday: Occasionally Read the Experts

What makes someone an expert is often not only their skill, but their experience. This includes knowing what shortcuts to take, when, and why, and what shortcuts to avoid.

Being an expert can also include knowing what basic requirements of success are absolutely essential, but are often lost in the details. Or, they know how often the forest gets missed for the trees.

I just finished reading the book Couture Sewing Techniques, Revised and Updated by Shaeffer. Do I intend to make a couture garment? Not any time soon. Do I intend to buy a couture garment? Not unless I have a lot more money than I have now. Did I learn anything useful? I sure did. Among other things, I learned some things about how shirts and jackets are supposed to fit when they fit correctly. I learned some things about making pockets.

The biggest thing I learned was why that level of tailoring and dressmaking costs so much: it’s not because of all the handwork, but because the handwork is combined with expertise in appearance and construction to make garments which are comfortable to wear and really flatter the wearer.

The word “technology” can apply almost any skill or craft. From the Online Etymology Dictionary, the etymology of technology:

technology (n.)
1610s, “a discourse or treatise on an art or the arts,” from Latinized form of Greek tekhnologia “systematic treatment of an art, craft, or technique,” originally referring to grammar, from tekhno-, combining form of tekhnē “art, skill, craft in work; method, system, an art, a system or method of making or doing,” . . .

D. Harper. “Etymology of technology.” Online Etymology Dictionary. https://www.etymonline.com/word/technology (accessed November 22, 2022).

For the purposes of this blog, I usually use “technology” to mean electrical, electronic, or computer technology.

But there lots of fields, lots of “art, craft, or technique” which have varying levels of skill and expertise. It’s still a human creating something. And the end user of the created thing is usually a human.

“If it’s expensive, it had better be comfortable for me to use, or make me look good in front of others”: that’s why it’s worth reading the experts.
