A Change of Direction. Is Longer and Less Often Better?

I found the site Create And Go. They have a very nice post about blogging in 2023.

One of their recommendations is longer and more in-depth posts. And to do that even if it results in less frequent posts.

I am happy to hear that. I like longer and in-depth writing more anyway.

I started this blog over a year ago. I’ve enjoyed writing it. I enjoy writing about the topic of people using technology. But I have struggled at times to meet my self-set goal of two posts a week.

I’m not sure if I’ll continue this particular blog on this domain, or change to a different domain. That will probably be the first long-form post for me to write, to really consider that question.

Excel Files Are Zipped Files

I do remember reading this before. I hadn’t realized what all got zipped up in those zip files.

Among other things, there is a file called calcChain.xml. This shows the order calculations are done on cells in the Excel spreadsheet.

That in turn can be used to figure out if cells have been moved around the sheet.

Data Colada has more information in their (very fascinating) post “[109] Data Falsificada (Part 1): ‘Clusterfake’“. It is dated June 17 2023 (and last accessed for this post on August 5 2023).

I have no idea if this is true of other spreadsheet types, like the LibreOffice Calc spreadsheets.

A Nice Radio Programming Program

I recently purchased some handheld radios. Now it is time to program them. The vendor recommends RT Systems, Inc. for the programming software.

So far, the company, website, and program are impressive. There’s a huge list of radio brands their products will program. Their website has how-to videos and nice knowledge base section.

Although I’ll use the software to program the radios now, I’ll still take the time to familiarize myself with how to program them in the field. While listening to an ARRL On the Air podcast, they mentioned the importance of knowing this. Getting it programmed just right, at home, is great. But sometimes I’ll want to change that when I’m not at home. It’s better to know how to do that before I need it.

It’s Old, But It’s Still the Best: Email Part 2

I listened to episode 699 of Pat Flynn’s Smart Passive Income podcast. He interviewed Matt Giovanisci. They talked about online businesses. At one point, Giovanisci said what he’d learned was “Content Is King and Email Is God”.

I wrote last week about going through bunches and bunches of old emails.

The one which were the most meaningful to me, in some cases several years after they were sent, were the text-only emails.

Email which sent images or video now had broken links. In many cases, the broken link was the entire content of the email. Those emails might have meant something in the moment (maybe). But now that the links no longer work, they were not much use.

I kept many of the text only emails. The emails I kept had context, are self-contained, and don’t depend on any server besides the email server. Email was king.

It gave me a lot to think about. It also gave me a lot to think about when it comes to any lists I might subscribe to.

Well, Now I Feel Silly: Handles, Revisited

Just a day after I wrote a post about not finding much information on handles, handle design, or handle shape, my inbox received one of AAW’s regular emails. This was a showcase all about handles and AAW articles and videos about handles.

So, my gripe has been answered by God and cosmos, with a bit of a chuckle at my expense.

If I can get some good information about the how’s and why’s of handle design, I’ll be fine with the ironic timing.

The Paradox of Specialization, Too Little and Too Much Are Both Fragile and Unusable

Handles: How Do Companies Decide On The Design?

I originally started thinking about this while contemplating handles. Handles are something we ignore when they fit our hands well, and hate when they don’t. Yet, I cannot find much information on study of handle design. There are specialty handles, like various grips for fencing weapons. There are ergonomic handles for specialty carpenter’s hammers.

But when it comes to the simple round handle on many hand tools, I don’t find much information on the design of those handles.

Then I realized this sort of makes sense. Yes, at one time it might have been possible to go to a local woodturner, explain what a person wanted in weight, balance, size, and so on, and get a good fit for their own preferences.

Now, most handles are mass produced. There’s the occasional shovel, broom, landscaping tool, or gardening tool with wooden handles. But I think they are becoming rarer.

Once a station is set up to mold handles out of resin or plastic, handles can be produced far faster than any woodturner could produce them.

Once that station is set up.

Getting to that point is a long process of decades of scientific and chemical research to create the resins and plastics. And decades of scientific, chemical, thermodynamic, and mechanical research to know how to create the molds, heat the plast or resin up to the correct temperature, inject it, take it out of the mold, and so on .

This is an example of overspecialization. It does what it does, very well. But it can’t be easily changed to anything else without a new mold being made. And there is a long supply chain between the natural precursors of resin or plastic being gathered, and the resin or plastic coming into existence.

On the far end of under specialization, there is a hunk of wood and a knife. Yes, a person probably could make a handle for an implement out of that. It would take quite a while, and probably be fairly crude.

Another example: Writing Programs

Another example is writing programs. Microsoft Word tries to be all things to all people. And it is amazingly annoying and bloated because of that. Scrivener is so specialized, I have tried to use it and like it several times. But it is just a bit too specialized for the more general purpose use I want to use it for. And LaTex is definitely too specialized.

Electric Motors: Power at Low Speeds

I’m currently reading through one of Bernie Tobisch’s books on sewing machines.

He mentions that older sewing machines have AC (alternating current) motors. These are simpler to build, but have low power at low speeds. He said this is why sometimes when first starting a seam, the sewist (which is a nice term, once I haven’t heard often) might have to turn the handwheel by hand to get the motor started.

He writes that newer machines have DC (direct current) motors. These have better power at low speeds. But they are also more complicated to build. Most houses aren’t wired for DC voltage. (I’m saying most because I’m sure somewhere there was someone who ran some DC power lines through their house.) Most houses in the U.S., 120 Vac RMS is what comes out of the wall. That will fry almost any DC motor. So, DC motors get used, but there’s more circuitry involved to make them work.

Somewhere I have a book about using small electric motors. I wanted to look at it the other day, so maybe I’ll spend some time this weekend finding it.

Identify the Problem, Part 4: ADP Destroys Its Own Numbers.

My Irritation

Yes, I’ve been ranting for a while now about the need to identify the problem before going hell bent after a “solution”.

The examples keep showing up. Here is another example:

“ADP, for example, changed their methodology to try to produce a job number that would be more predictive of the NFP data. Why they would take their own unique payroll data (and manipulate it) to try to estimate the official government data is beyond me, but they did it. So, ADP isn’t really trying to analyze how many jobs were created, it is trying to produce data that helps people predict NFP (at least the Establishment Survey).”

Peter Tchir, “Sherlock Holmes on the Jobs Report“, Zerohedge, dated June 11 2023, last accessed June 29 2023. Emphasis in original.

ADP is a payroll company. Producing jobs numbers is not their main job. But their jobs report is often looked at as another indicator of employment trends in the U.S. economy.

Tchir’s whole article, “Sherlock Holmes on the Job Report” in Zerohedge, dated June 11 2023, was about trying to make sense out of numbers that didn’t always have as much sense as a person would hope for. The paragraph about ADP changing its own numbers was one of many.

But in a sea of weirdness, it stuck out to me as being particularly weird. What problem was ADP trying to solve?

  • If the attention to their payroll report was interfering with their business of providing payroll services for companies, why not say that and stop with the report entirely?
  • If they were doubting their own internal numbers . . . I can’t think of any reason why they’d doubt their own internal numbers. But if there was some reason for that, I’d expect them to put the report and almost everything else non-essential on hold until that doubt got resolved. If I doubted the numbers for a core part of my business, resolving that would be top priority.
  • So, what “problem” does that leave, that this would be a valid solution? They wanted to stop using their own numbers, while not making it obvious they were no longer using their own numbers?

How is this related to technology?

One of the primary uses of technology, of all types, is manipulating information. Gathering it, tracking it, saving it, collating it, sorting it, looking for patterns in it.

Computer software in particular is really good at manipulating information. In a way, that’s a definition of what computer software is and does: it manipulates information. It manipulates it far faster than humans can.

There’s the perennial problem of GIGO – Garbage In Garbage Out. If the software starts with data that is bad or wrong, it’s output will almost certainly be bad or wrong.

But there’s a less recognized problem: solving the wrong problem.

Another Look at Business Band Radios

Yes, I know I said I’d start working on learning websites.

The best laid plans of mice and men and all that.

I’m back to looking at business band radios. I’m noticing odd stuff about the market.

There doesn’t seem to be nearly as many companies making business band radios as companies making amateur / ham radios. That surprised me.

The ham radios often have a description of their power output. I’m not seeing that as often on business band radios. I’m not sure if that’s because there’s a set maximum output for business band, or if it’s because hams will look for output power specifications and business band radio customers don’t.

I am also wondering if GMRS has consumed most of the business band market. Doing a bit of reading, it sounds like GMRS is a far easier license to get. That also means GMRS can be crowded in some areas and the main benefit of business band is less competition for airtime.

Viewing Formatting Marks, MS Word and LibreOffice Writer

This is a quick tip I’d wish I’d known earlier.

If I want to view the paragraph breaks, spaces, hard spaces, and so on in a word processor document, “Formatting Marks” is the setting.

In Microsoft Word, it’s Ctrl + *, or Ctrl + Shift + 8. In LibreOffice Writer it’s Ctrl + F10.

Years ago, I used to use Scrivener. I have no idea what key combination that program uses Formatting Marks.
