This sounds like just standard traffic analysis. Nothing to do with WhatsApp or any other messaging platform. It’s been in use since at least WWII.

Who is talking to whom? How often? Under what circumstances? How do patterns of communication correlate with events? Who are the hubs of communication (ie leaders)?

The big difference between then and now is that instead of needing rooms full of people drawing graphs by hand, there is software to handle it. In turn, that means it’s not really important to have initial suspects to get started, because the computers are quite happy to tease out interesting signals from total communications. That also increases the likelihood of false positives, but the kinds of people who do traffic analysis at this level aren’t usually the kinds of people who worry about a little collateral damage.

It seems like a pretty tall order to construct a system of communication that is useful for coordinating activities, affordable to operate, and secure against traffic analysis. At best, you’ll end up back in a situation where other intelligence will be required to identify a manageable pool of suspects.

They’re called “dessert forks” in the same way that some people call the small spoons “dessert spoons”.

Until now, I’ve never seen anything with epoxy that I found visually impressive. And you went all the way to stunning!

I try to figure out what it means from a combination of context and etymological guesswork, then check it a dictionary. If it’s a person or region or concept I’m unfamiliar with that isn’t covered directly or in notes, I hit the encyclopedia or atlas (well, Wikipedia and mapping software, these days.)

That’s how my father taught me to deal with stuff I didn’t understand when I was a kid and I’ve been doing that ever since. It interrupts the flow far less than having to set it aside for other demands on my time, so it’s not that big a deal.

We always had good dictionaries and encyclopedias on hand. Now, of course, it’s all online or downloadable.

One of the reasons I love eReaders is direct access to dictionary, translations, and Wikipedia.

Tell me again why it’s okay to publish this tripe. It’s no wonder that so many women think men are pigs.

Heh. I agree. My only experience with Xplornet was in trying to support people who had it. No internet is far preferable.

We bought a cabin at the lake with an eye to retirement. Dysfunctional workplaces led us to move there nearly 15 years early. We figured that if we were going to work anyway, we might as well do it in a restorative environment.

There is no cell service, landline service is noisy enough that my very nice modem is lucky to hit 20 kbps, and I knew too much about ExploreNet to tolerate their “service”. I’m no fan of Musk or the concept of Starlink, but the price/performance is stellar (sorry) and it’s nice to be able to get stuff done without having to drive in to the library, especially given that it’s only open 15 hours a week.

I spent a decade without internet. I never did figure out how to get Chromecast to work. Even for plain screen casting it insisted on needing an internet connection. Most of my stuff at the time was YouTube rentals that allowed downloads, so I got the hardware that let me use HDMI to connect my phone to the TV.

Canadian here, with 50 years in the workforce. I’ve never once been paid semi-weekly or bimonthly. Here, biweekly is every two weeks semi-monthly is every half month. Obviously, that latter is often spoken of as twice a month, which just adds to the confusion between “bi” and “semi”.

The reality is that these words, like most words (at least in English), mean whatever the speaker wants them to mean and consensus can be hard to reach.

I give you the phrase “table the discussion”. Sometimes it means to formally bring something up for discussion. Other times it means setting the discussion aside for future consideration.

Or, my favourite from my childhood, “fat chance” which means that something is even less likely than if it had a slim chance. Granted, that might be more in the line of idiomatic slang, but it stands as part of at least the era’s Canadian English that did have broad consensus and still does, I think.

“Semi truck” is not half a truck, but a truck designed to carry one half the weight of the cargo it is hauling. A semi trailer is one designed to have half of its load (by weight) carried by the tow vehicle. A standard trailer gets difficult and possibly dangerous to tow if the weight carried by the tow vehicle (hitch weight) strays too far outside the 8%-12% range.

And just to add to the confusion, Dodge popularized something called the “hemi engine”–an engine with a “hemi head”, not half an engine. And “hemi head” refers not to “1/2 an engine head” but to the approximately hemispherical (1/2 sphere) shape of the combustion chambers cast/machined into the engine head.

Language is a wonderful chaos. You’re just on the leading edge of change! :)

Are you sure about that? I’m from Canada and distinctly remember the travel ads urging us to head on down to participate in the bicentennial celebrations, meant to celebrate the second century of that country’s founding.

I was taught that the “bi” prefix was a multiplier and “semi” was a divider.

That meant biweekly, bimonthly, biannually were every 2 weeks, months, years and semi-weekly, semi-monthly, semi-annually were every half a week, half a month, and half a year.

Then the real world intruded and I’ve been confused ever since. About the only time I hear “semi” and “bi” used on a regular basis the way I expect is with pay periods. Biweekly is every two weeks and semi-monthly is twice a month.

Canada, by the way.

PS: I suppose bisexual and semi trailers also fit my expectations.

And plants.

Looks like it still has rubber tires, so probably just fine.

I can see why! That’s beautiful!

And if you tape it into the corner of your combination square:

• the rule part of the square keeps the reference faces aligned vertically
• the nail can’t tip toward one board, causing vertical misalignment
• consistent centering (or off-centering, if that’s what you want)
• I find it’s easier to position the rule on my layout markings than to position a handheld nail. There is a slight offset, of course, but if that’s a consideration, do your layout to compensate.
• I find it’s quicker, too.

If you are doing floating tenons, just mark the ends. If your tenons need to be vertical with respect to your reference face, use a long nail or screw, mark the tops, adjust the height, mark the bottoms.

If you can tolerate more offset or are willing to always layout to compensate, drive a woodscrew vertically in a long narrow block with only 2 square faces. Adjust the screw depth as appropriate. The block gives you something to hang onto without taping anything.

And now I bet you’re envisioning the construction of your own dedicated jigs made from scraps and wood or drywall screws.

Thanks for the book recommendation!

It’s fairly expensive, but it turns out that there are several copies of both first and second edition available through my local library.

There were (and are) natural radio waves from things like stars and even something known as the Cosmic Microwave Background, the product of the Big Bang that created the universe.

However, they are not like rivers that we exploit for transportation, irrigation, and energy production. Instead, we have to generate our own radio waves to serve our specific needs.

In this sense, I find it useful to think of something like a lake. There are natural waves created by the wind, but I find it difficult how to imagine we would exploit those waves for communications because there is too much randomness built in and we have no control over the wind itself. On the other hand, it’s relatively easy to imagine how we might create our own waves in patterns that can carry information.

An interesting thing about generating water waves to communicate is that it would be extremely difficult to make it work in practice. The waves degrade quite quickly over distance, so would need periodic repetition and amplification. Natural waves would mess up and possibly overwhelm our nice patterns. Other people trying to use the same body of water at the same time would be creating waves that would mess up and maybe even overwhelm our nice patterns. To get radio communications to work, people have to figure out how to deal with analogous problems with signal degradation and interference.

No problem! If that’s as nasty as we ever get, then I’d say we’re doing pretty damn good!
