The kids all know they are going to be killed by Climate Change, and
have no future and will never have kids of their own, so may as well
get it over now.

How Dare You! Meaning us, for making their lives so miserable.

Looking out of our kitchen window, we see frost on the roofs of the
houses on Sussex Street. We've never seen that before, in 30 years.

So, warmer ocean to the west causes higher humidity during winter
than previously seen? Or, did you just never pay attention to the roofs?

Probably the first; news reports say statewide snowpack in California is
abnormally high right now.

The Sierra snowpack changes radically from year to year. It's been
measured the same way in the same place since 1879 and there is no
longterm trend.

I just paid $130 to have our deck cleared at the cabin. I'm
contracting to have it done after every big storm, so it doesn't pack
into solid ice or break windows or something.

Sugar Bowl has had 155" so far, and the winter is just getting
started.

Indeed, I'd go for a 4046 in that case...
Done it many times

People have no clue, in the old days, we did nano second locked
loops for TV sync and color subcarier country wide (from reporting location),
Wow and TV was real time, now you often get a pause before a reply in remote interviews
as the digital processing takes seconds,
maybe even goes up 40,000 kmand then down 40,000 km to a geostationary sat too.

I woke up early and the thinking started, about US and
like who's fault it all is, and of course you know its Andreas fault,
and supperman will come to help
but supperman was invited to our cryptonight and found out
he could no longer fly and said: "What the Hack is going on?"

As to Andreas, I have this theory that the earthquakes happen
more when the earth wobble reverses direction (so around December
and July...)
It all about resonances, if we all tap the table at the right speed in those
periods we can test suppperman.

This all for Martin ;-)

It was -6 C here a few days ago.
But I have seen -40 C once in the eighties.

Many mistake weather for climate change it seems.

Well people were skating again!

The big lakes aren't drying up, they are being drained.

And if you prowl the world, you can always find something to terrify
you.

The kids are sitting at tables outside of cafes under big umbrellas,
drinking $8 coffee with $12 toast, and complaining about the horrible
world we created for them. Get used to it, buttercup.

I'm being bankrupted paying to have snow removed from the driveway and

March. 80 feet on the summit in a good year.

I bet those $150-per-snowstorm charges are pushing your credit limit. ;)

The climate panic thing is actually pretty remarkable--the folks pushing
it have figured out how to make it last far longer than most such
vogues. Of course the folks with the money are still buying beachfront
property.

We'll see. I'm still a devotee of John Searle, and he's quite

The main thing tech has given us, along with galloping
advances in machining precision, is the ECM and its analog in air and

In the UK it is Archaeology & Anthropology for the brighter ones and

Surprising amounts of money on top university sports events.

Er.. not really... :-)

Very, very common misconception.

Maxwell 's Equations predict an "ether" velocity, as any standard derivation
shows, such as:

https://www.kevinaylward.co.uk/gr/xht/GTMaxwellsEQ/GTMaxwellsEQ.xht
https://www.kevinaylward.co.uk/gr/html/GTMaxwellsEQ/GTMaxwellsEQ.html

The MMX experiment was constructed to detect such a variation.

Einstein's motivation to take the SOL as a postulate was because *if* MEs
were directly correct,
then they implied that the Newtonian Principle of Relativity (POR) was
false.

However, experimentally EM effects appeared independent of inertial motion,
thus the failure of the POR was a problem

The resolution to the apparent failure of the POR in MEs, was to use the
Lorentz Transformation.

The LT applied to MEs *then* "predicts" an invariant SOL.

Einstein was trying to save the POR. Saving the POR is what led to the SOL
postulate because he took MEs as correct.

https://www.kevinaylward.co.uk/gr/sr/xht/srbackground.xht
https://www.kevinaylward.co.uk/gr/sr/srbackground.html

An anthropic argument can be made as to why the SOL must be measured as an
invariant.

Consider all the constants in physics.

https://en.wikipedia.org/wiki/List_of_physical_constants

Pretty much all of them involve c, via the fine structure constant.

The physical properties of atoms thus contain c.

The laws of physics, based on those constants, are such that atoms can do
things such as bond with other atoms. If any of the constants changed with
motion, these properties may well result in the atoms dismantling
themselves. Thus, the laws of physics must remain the same, thus c shouldn't
change with velocity changes.

Seems pretty obvious after the fact.

The only annoying quirk I have found is that for some shapes of contour
plot the left axis title is half hanging off the edge of the plot area.
I'm down to final publication tweaks. There is also more white space
than I would like at one top edge but that is only a minor irritation.

Using Latex is required now by several major publications. They provide
the template and it automatically becomes in house style. I still
haven't been able to fully master bibtex yet which is a PITA.

I have just about learnt enough of the structure to manually edit EPS
files to fine tune the appearance and make minor changes to labels.

Publication doesn't like 1e-10 notation so it has to be 10^{-10}

Reduce was the first one I came across that could actually do things
that were seriously not obvious and would ask where to put a branch cut
when given an awkward integral to solve. Maxima can be awesome!

It sat on top of a Lisp runtime (no small thing itself) and required
insane amounts of mainframe resources to use it (all 4MB at once!!).

Thanks for that. I'd not heard of KLEE - although I was always a fan of
McCabe's complexity metric which counts and if you are lucky generates a
minimum number of test cases to ensure every path of code is explored.

Sometimes it is just chance but more often than not patterns I see are
real and some of them are even useful.

One problem with machine learning and neural networks is that you can't
sensibly ask it why it comes to a particular conclusion?

Also designer images can be created that get insane answers from "smart"
image recognition systems. Obvious enough to a human but with enough
subtle correlations that the machine sees something else entirely.

That's 5 years old and they have improved a bit since then.

In my experience, 10^{-10} gets mangled in abstracts, whereas 1e-10
obviously does not. My personal preference is 100p.

I once wrote Boltzmann's constant as 13.8 yW/Hz and it got edited
into 1.38^{-23} J/K, which is correct, although not very handy in
the context of electronic noise. The times after they left it alone.

Erm, 1.38⋅10^{-23} J/K, obviously. But you understood that

I am amazed that they can even do as good a job as they do, placing labels
without (too much) conflict. I let the software "draw the plot" and deal with
the "decorations" myself. Especially if I want control over typefaces
or positioning.

Some (most?) of the FOSS "packages" seem to rely on volunteer labor
to build/test to the extent that the folks doing the work are just
"warm bodies" and not necessarily "qualified" for the task at hand.

I first noticed problems in a gnuplot binary when I ran the test
suite (to see the pretty pictures) and saw a CDF that wasn't
monotonically increasing. ("Huh? That can't be!") This prompted
me to build my own binary and actually *understand* the errors
(warnings) that were thrown during the build.

Thereafter, I never relied on a prebuilt binary -- of anything FOSS! <frown>

Ah, that makes sense. Esp when dealing with submissions from a variety of
authors each of which may have their own sense of how the document should
render.

I (was) fluent in PostScript so I can read "code" and sort out the intent
even when the code is machine generated with nothing that resembles human
constructs. This is how I build the gesture templates (serieses of beziers
encoded in PS) for my gesture recognizer; it's easy to see all of the
cruft that is put in place for the "human" vs. the code intended for
the rendering engine.

IMO, this is the real "value" of software. Yeah, it's nice when it
automates mundane activities or speeds things along. But, when it
can *faithfully* do something that you were *taught* to do (but are
likely to make casual errors doing!), it's a godsend!

KLEE is a big of a pig, execution time-wise. But, it manages to
examine *all* of the cases that you know *you* should have done.
So, just let it chew on something while you move on to work on
something else!

Yup. My first successful application was as a prequalifying stage for
the gesture recognizer. I use a Rubin-esque feature based qualifier
to quickly reduce the set of *likely* candidate gestures to a small
number by computing real-time bogo-metrics on the sample input
(e.g., overall gesture aspect ratio, jaggedness, total angle displaced,
etc.) and comparing to the precomputed set of such metrics for each of
the templates for "likelihood of fit". Then, retrain the algorithm
with the results of the recognition task (which is confirmed/overridden
by the user's acceptance/rejection of the gesture I acted upon: "No,
that's not what I wanted you to do!")

I can look at the coefficients in the NNet and get a *feel* for what
is important in the process. But, ask me why a particular coefficient
is 0.27 instead of 0.34 and I'll just shrug.

Yes. But, how much of that is not knowing *what* to extract from the
image as "significant"? I don't like just blindly throwing the
complete dataset at a recognizer because you never know what IRRELEVANT
detail it might focus on. This evident in my gesture recognizer as
a human likely looks at the "features" I mentioned to determine likely
candidates (e.g., a '0' had a different total angle than a '7') so
give the AI that information instead of letting *it* decide what to
extract from the image.

E.g., the NNet that I use to filter USENET posts doesn't operate on
complete posts (like complete images!). Rather, I sort out the things
that I use to manually make those filtering decisions and design
my input neurons to signal those characteristics:
- pTopPost
- ratio of new to quoted
- pRealSender
- pProfanity
etc.

Otherwise, it could be that the network decides the number of vowels
in a post is the most significant factor! (rolls eyes)

The neural net AI community is well aware of this problem. When
they fail, they fail spectacularly, and no can explain.

Which means use in safety critical applications is a long way off.
But you wouldn't know that from the hype - "thinking machines are
just over the horizon!"

And there are plenty of Pentagon Santa Clauses willing to abide,
which is the important thing -

Still, there are areas where they outperform humans - hello,
Jeopardy champion - so stick to those, and it's a net gain.
