Why do circuit breakers go up for on and down for off?

Clairmont Canyon regional preserve, most likely. Great views on a clear day. Mt. Diablo has good views, as does Mt. Umunhum south of San Jose.

Around here a Subaru Forester and a Labrador with a red kerchief are issued at birth. I like dogs but I wish their owners were bright enough to realize you're supposed to take the little bags of s*it with you. The cartoon instructions at the trailheads omit that part.

One of the things I enjoyed about the PNW was the profusion of blackberries along the bike trails. Of course if you wanted to go anywhere but the trail you were out of luck.

The Montana Forest Service fire crews sometimes get sent to California. There isn't that much poison ivy in Montana and afaik no poison oak. Their species recognition when tromping through the chaparral isn't that great either.

You need to pick and choose in Colorado and Utah. Denver and SLC are colonies of California.

I didn't find it scary. When I left NH I gave my development boards, manuals, and computers to a teacher trying to patch together a high school computer course. Everything else that didn't fit into my pickup was given away one way or the other. I left a rowing dingy on the beach above high tide. Hopefully someone found a use for it.

I spent a year as a volunteer on a Forest Service mule ranch. When I was a kid I always wanted to drive a truck so I drove OTR on and off for a few years. The nice thing about that is I could quit, spend the winter in AZ, and hire on again in the spring. It was about 10 years before I went back to programming.

We have Teslas and custom bred-to-order labridoodles. The Brat is unusual in adopting SPCA mutts.

Everyone here that walks a dog carries poop bags and uses them.

Lots of people have a nanny for the kid and a walker for the dog. Kind of like the classic british aristocrat who seldom made contact with either.

On a clear day, from the ranger station on Mt Tam, you can see clear across the state to the snow-covered peaks in the Sierras. Growing up in steamy mud flats with hundred-yard views, this still impresses me.

Issue is worse, since it has other meanings like the issue number of a magazine, or "I issue you with a warning".

You must live where the mains is around 50 volts i expect;!.

If you had 230 across from one hand to the other gripped around something conductive then just maybe you'd still be able to let go with that lizard skin;!..

Never seen a 50 ma one has anyone?..

How?..

My family drove cross country in '52. When we got to the plains my father would carefully record the mileage when he first spotted a grain elevator in the next town. In an hour of so you finally got there.

No mud flats in my youth, only heavily wooded terminal moraines we called hogbacks. I'd read articles about 300 yard shots in Field & Stream and it wouldn't compute.

There are a couple of dog walking services here. I think I've seen a few in action on trails or else the person couldn't make up their mind on a breed and were trying one of everything.

I can sympathize with the ones that are white around the muzzle and as old as I am in dog years bringing up the rear of the pack, or I should say trailing the pack by 50 yards.

That was quite an adventure in 1952. Start out with a brand new car and you get to the other coast four oil changes later and probably need a ring job.

No, it would not. It would be around 5kbps

Shannon is about digital communication of *information* , not Nyquist's sampling theorem.

The *information* rate on speech is far far less than the bandwidth needed to accurately reproduce it. Which is why it can be compressed at all.

With a speech synthesiser and a speech to text analyser you could probably get speech down to about 50 bps. It would lack nuance, but would be comprensible

Stripped of constants and caveats Shannon says that you can get no more bits per second down a channel than the channel bandwidth times the signal to noise ratio.

All the fancy modulation schemata are simply ways to approach that given a particular channel degradation .

Nyquists theorem is about how many bits it takes at what frequency to

*fully characterise* an analogue waveform of *arbitrary* nature.

Ex of digital signal processing - as on say a CD - that's a lot for full audio. But speech and music are *not* arbitrary. Quite the reverse. The actual signal does not - except in the case of white noise - carry anything like the information rate implied by the data rate. And the lack of high energy high frequencies means that very simple algorithmns like delta encoding can drastically reduce the rate needed at the expnse of truncating very high frequenciy transients. A cymbal clash for example.

And the human ear does not do phase very well. Yu can dor fouurier transforms and resynthesise to audio and lose all pahse coherence and you wont notce it.

Hnce the MP3.

Yes. I used to walk the dogs down a path adjoining farmland and private woodland and the farmers were quite happy to let the dogs s*it anywhere. There was no requirement to collect poop, and if it wasn't dog, there were plenty of foxes badgers deer, feral ferret, stoat, weasels and rabbit and hare poop you could step in.

I mean, this is the f****ng COUNTRYSIDE. It's full of poop. After a week something would have eaten it anyway and recycled it.

Unless its been carefully scooped placed in a vile green non biodegradable plastic bag and hung on a tree.

The patterns of distinct colours confuse perception. If you don't see the colours as distinct, you won't be confused.

I said "Sampling Theorem" above, namely

which is not digital nor quantized.

Per the sampling theorem, 3.5 KHz audio needs to be sampled at about 7 KHz. Digitized to 8 bits, probably companded, that's a data rate around 60 Kbps.

Voice has redundancies and patterns and silences so can be sent at much lower bit rates. Utimately one could recognize words and send voice at maybe 50 bits per second.

Are they leaving it on the trail, where people who don't look where they are going step in it?

No, they hang it on tree branches, because there are no doggie bins for miles.

Sounds like my lawn (garden) as the snow melts. The largest fraction is from deer but the cats, raccoons, and odd coyote contribute. The skunks don't wander around much in the winter so I can't blame them.
