British filker Talis Kimberley has a spot on her local radio station this Friday
4th December, and you can listen over the web.

The station is Swindon 105.5 at http://www.swindon1055.com/ - see the "Listen Live"
link.
The show is 'Art to Art' at 1pm to 2pm GMT
She'll be doing "a couple of live songs with a bit of a chat" - I don't know at
what time during that hour.

Which should be... 8AM Eastern US? (I always get confused about whether
5 hours is the base time difference or with the summer offset.)

I'm very fond of the World Clock at
http://www.timeanddate.com/worldclock/

Right now it's 12-1-09 23:13:11 GMT/Zulu/UTC
and 3:13 PM Pacific Standard Time, which should mean it's
6:13 PM Eastern Standard Time.

I have a program called ALPHA CLOCK on my system
www.irnis.net is where you find it. It is free, and designed for by/for
ham radio operators . This puts a small digital clock wherever you want
it on your screen and you can set it to either "Local" time or UTC, so
right now I show 8:27 in the bottom clock and 13:27 on the Alpha Clock..
Very handy.. It's one of several "dual time" programs on this laptop.

On my iPhone, the clock App lets me define several specific locations and
what time it is at each. I have it set right now to display Boston,
Madison WI, San Francisco, and London on a single screen.

(I can actually do those in my head pretty easily, but it's a nice reminder
of where some of the people important to me are and what time it is in
their day.)

I like my DST overlords!! Of course San Diego is on the east side of the
pacific time zone, Arizona is on the west of the mountain zone. That
does affect when the sun sets. In the summer it sets at 8pm so we get
more light in the evening. This I like.

Though I understand your feelings, and that is why they invented DST to
begin with... It's wrong.. You get the same amount of sunlight no matter
how you set your clocks

Would it not be way, way, way, simpler for your employer to have summer
and winter hours.. Winter you work, (To quote the title of both a movie
and a song by Ms. Parton) Nine to Five

Summer you work Eight to Four

And you get the same effect.... Without messing up your clocks.

That, to me, would make more sense.

I also have "Multi-clock" apps for both my computers and my PDA (If that
is I can ever re-locate my PDA)

And, the time zones I use, which include Eastern, Central, Mountain,
Pacific and Greenwich (London's time zone) I can also do almost without
thought I have been doing them so long (Over 40 years since my user ID
was issued me) We use Universal time (London) for logging as it
simplifies things with contacts in several time zones.. If we all use
the same clock, we don't constantly have to think of stuff like: If It
is 9pm here. What time is in in Guatemala?" I just send the e-card with
Universal Time (GMT/CUT/CTU) on it and he knows that it's a legit
card cause his log has the same time code.

(By the way.. I worked Guatemala just a couple nights ago.. PSK-31
contact, That means my computer talked to, and listened to, my radio,
his computer talked and listened to his radio and via the radios our two
computers had a very nice chat.... Of course he and I were doing the
typing :)... I spend way too much time typing :) )

The legend goes that we tried DST one year (1965 or 66). I think the
sun set the next morning. Seriously, we don't want to "save"
daylight, we want to box it up and ship it somewhere else. (We have a
lot of it, so we'd expect a bulk rate)

DST really messed me up one year at BayCon. (which is considerably
west and north of San Diego) I was really looking forward to going to
this Chesesteak chain up there. Well, we went out to get dinner and
the place I wanted to go to and 3/4 of the other restaurants were
closed. I'm trying to figure out what is going on, it's not that
late, it's still daylight for Ghu's sake. It was 9:30 at night, or
should I say 9:30 in the afternoon?

Westercon in Vancouver (July 4th weekend) saw sunset twilight after 10
PM and morning twilight around 4 AM, if I recall correctly.

But Baycon sunrise/sunset figures aren't that extreme.
See http://www.sunrisesunset.com/usa/California.asp
This year for May 25th, sunrise was 5:51 AM and sunset was 8:16 PM.
And yes, that's Daylight Savings Time.

Maybe what you were seeing was urban light pollution.

It could have been WesterCon instead of Baycon (they were a month or
so apart at the same hotel).
Also to me daylight = sunset +45 minutes (i.e. civil twilight, no one
has their car headlights on yet), I understand you have your reasons
for thinking that daylight ends exactly at sundown though.

July 1st in San Jose had sunrise at 5:50 AM and sunset of 8:31 PM, again
that's DST. It still ounds like urban light pollution.

I was taught to put on my car headlights half an hour *before* sunset.

And I keep track of the time when off at a filk because sunset Friday
marks when I stop selling stuff (though I still give copies to
subscribers or contributors) and sunset Saturday plus about 45 minutes
marks when it's dark enough to see three stars/planets so Sabbath is
over and I can start selling stuff again, so I think daylight lingers
about 45 minutes after day ends with the sunset. I might also refer to
that time as "magic hour" (because of having the late filker/fan/
would-be cinematrographer Ted Johnstone (mka David McDaniel) as a good
friend until he died back in 1977.

We're used to coming home from a filksing at around 1 AM and seeing the
sky a twilight gray because of urban light pollution in West LA (though
usually I need to bark at the back porch light or Barry needs to rap on
its light bulb -- either of which will turn the light bulb on, so he can
easily see the keyhole to unlock the door).

Well, since we seem to have turned this into a serious topic hijack.
I know what urban light pollution looks like. I wrote Cochise
County's dark skies statute. I even wrote a Filk:


Four Stars
Music and Lyrics Copyright Mark E. Horning, 2009


She grew up in the city. It's the only life she knows,
Surrounded by glass buildings, and the neon city's glow.
And the only stars she's ever seen were on the picture show...
But there's four stars out tonight...

Refrain:
There's four stars out tonight
Four stars puttin' up a fight
Four stars, shinin' with a light
Yes, there's four stars out tonight.


Light posts at every corner to keep the night at bay
She glances at the heavens as she stumbles on her way
And wonders 'bout those points of light, shinin' through The Gray
At those, four stars out tonight...


Because we fear the dark, we have cast the night away,
But the light that's shining in her eyes won't keep her safe today.
In fact they only make her safer, better, easy prey,
Beneath four stars out tonight.


We've cast away our heritage, we've cast away the night
And trapped the very stars themselves in prisons made of light
She'll never see the majesty, or wonder at the sight,
Just, four stars in the night.


We can regain out legacy, the vault of all heaven
Turn off the lights, take back the night, restore the stars again,
I know that we can do it, though I don't know how or when.
Free the billions of stars out tonight.


Yes there's billions of stars out tonight
Billion of stars trapped by city lights
And one fine day we may regain the sight,
Of all those starts out tonight,

but there's just four stars out tonight
four stars puttin' up a fight
four stars burning oh so bright
just four stars out tonight
yes just four stars out tonight


Not recorded yet. I'll almost certainly put it on the next album
though.

If you want to see stars (either because you're an astronomer or just
because you like stars and meteor showers without having to drive off to
the wilderness), you want a city where streets and sidewalks get
illuminated by something that won't easily start fires -- but the sky
stays dark. As far as I can tell, no one is working on developing this.

I remember in the 1950s being able to see Orion's sword and we still had
fairly good street and sidewalk lighting. I could see hundreds (maybe
even thousands) of stars at night back then (even though I never saw the
Milky Way in LA). Nowadays I'm doing well if I can see fifty stars at
midnight even on clear nights (without sea mist from the Pacific Ocean,
only two miles away).

My experience is that city fires tie in more with flammable roofs than
they do with what you're using for lighting (candles, gas lamps,
electricity). A lot of fires that take down just one home start with a
frayed electric cord or a short circuit in wall wiring, but they don't
spread nearly as quickly to neighboring homes if flaming embers landing
on the roof don't result in a home catching fire. A decade or two ago,
Orange County (Disneyland area) was thinking of reprealing an ordinance
requiring new homes to have fire-resistant roofs, and a 4th of July
bottle rocket started a fire that took out half a block of old homes
with old-fashioned wood (non-fire-resistant roofs) and stopped when it
came to the newer buildings, and the county government changed its mind.

There are several shingles which do not burn, For example Fiberglass,
instead of asphalt. However the most common shingle is still paper
reinforced asphalt, Quality shingles will have rag based asphalt (much
stronger and the better asphalts do better in cold weather).

Of course out on the pacific coast "Mission" type roofs are usable, that
is clay half tiles. 100% fire proof if it's clean (not so if it's
covered in leaves) That too don't work so good in Michigan (I'm not in
Michigan just now.. I'm in S.C.)

Contrary Ms. O'leary's cow never kicked over a lantern in the shed.

Light pollution is very real, as is Radio Pollution (I should know) So
much so that observatories need to be built far from a city for night
sky viewing, and the government has established a radio free-zone for
some radio observatories (including one operated by the Naval
Intelligence Service) in this zone even some cars are prohibited as they
make too much Electromagnetic noise.

I used to know the law off the top of my head.. at least Michigan's
(Which says the headlights must be turned on either before or after
sunset by so many minutes)

When driving the Motor home I always drive lights on

The car has (Currently malfunctioning) Daytime Running Lights.

The malfunction, I think, is a dirty relay.. I hear the realy clunk on
schedule but no light... I"m working on it, but alas the module is an
epoxy block type box. I have another electrical issue on the car too.

And the maker of the DRL.. I've not been able to re-track down (he moved)

Yes, I know. They're the ones approved in Southern California.

They're a lot heavier and require more in the way of support.
I don't know how well they do at resisting breakage in winds of 50+ mph.
I'm absolutely sure they're unsuitable for areas that get snow.
They do insulate an attic better against heat/cold.

Last time we reroofed, we went with fire-resistant shingles. (I'm not
sure of the exact makeup. They're supposed to last thirty years, which
is probably longer than we'll last.) Our previous roof was put on in
1980 and was getting close to worn out in 2005 when we replaced it.

(I much prefer the system I had in my last car -- entirely automatic.
Running lights come on with the key, headlights come on ever time light
level drops below some very reasonable threshold. I'm a bit surprised
that latter hasn't become the universal default mode.)

It's a matter of what you want. Gratuitous light spill makes seeing the
stars much harder, which annoys many of us and is a serious problem for
serious astronomers. If you consider it an improvement, fine, but many
of us really don't.

Pollution, littering, whatever you want to call it -- it's wasteful and
unwanted discharge into a public space.

Seriously, how hard is it to keep your photons on your own property?
Most light pollution is the result of poor luminary design and
inefficient implementation. There is absolutely no reason why a
streetlamp should shine onto my property or into my window when it can
be shielded such that it only shines directly onto the street (and
sidewalk if applicable) where the light is supposed to be.

Would you prefer the phrase "photon trespass"?

A couple of decades ago, we got a noise detector that screws in between
the light bulb and socket. Its minimal level of noise is higher in the
daytime than at night, and you can adjust it. But nowadays night is so
twilight-ish that it takes a slammed door, a loud bark, or a touch on
the light bulb to activate it, even at midnight.

I don't think they make this any more, just the motion detector ones --
and I don't think those adjust so they're not apt to turn on when it's
daytime.

The motion detector ones should have a photocell that prevent them
from coming on in daylight and adjustment potentiometer to set the
threshold of what constitutes "daylight"

That's what I've seen, on the ones designed for outside use -- including
the low-end units. Not perfect, depending on the environment they're
used in, but Good Enough.

Our 25-year-old car has such a system (though no running lights). But
one thing it does NOT do is turn on the headlights when the windshield
wipers are going. That's now a legal requirement in California - but

Years ago there was a move to increase the use of low-polluting halogen
vapor lamps in properly designed fixtures to cut down the upward
component. I've no idea how that came out, though I do see a lot of
halogen vapor lamps around here. Trouble is, given the size of Los
Angeles, you still get an awful lot of it.

I don't know any details about the station, but obvious problems would be: Why add
just that one recording rather than any other? And adding everything would take
space and people's time. Even digging out one recording would be extra work in a
small volunteer run station. And what about rights? That show would have had lots
of other music as well. If they've only paid for a single broadcast, even just
researching and negotiating for the rights would cost far too much time for them.

But, as I say, I don't know any details - Talis might know more.

The advantage of the Halogen vapor or mercury or sodium vapor is not
lower light pollution. it is more lumens per watt, they are more
efficient at making light so they lower the city's electric bill.

Of all the electrical and electronics I have ever dealt with only one
item is 100% efficient and that is a space heater. (Since all losses
are converted to heat)

You could plug in a floor lamp

Another thought occurs to me.. A company in Marshall Michigan makes,
among other things, automatic doors, Now many of those today are
operated by motion detectors but in the old days they used mats.

One of the special mat designs they produced was 12" by 12"

It is used in mental hospitals and the like to track the movement of
people (you lay it right under the regular floor tile) and in stores,
banks and such as a silent alarm.. (Or as a "Security key") either
steping on the odd color tile trips the alarm, or activates the
register. depending on the set up.. Even better than a hidden button
since the bad idiots nearly never watch the feet.

That's for deliberately clapping to turn it on.
The original idea (like that of the motion sensor, I think) was to
notice intruders (in this case, ones who make noise) and unexpectedly
shine a light on them.

There is a light-pollution reason for some of these lights
(such as, I believe, sodium vapor). Their light is nearly
monochromatic. Thus, a filter for just that small frequency range
allows telescopes to get a non-light-polluted view of the sky.
Admittedly it doesn't help a person just looking up trying to see a
starry sky.

That is also true, the Mercury and sodium vapor lights are very "narrow
bandwith" which makes them easier to filter out.

Tungsten and halogen lamps (which are also Tungsten) are more "White"

By definition white is the equal presence of all frequencies
(Wavelengths) and pink the equal Energy at all wavelengths. (Though I do
not think that would look pink) and thus impossible to filter.

Black, is of course the absence of all wavelengths.


That is one of the differences between Colors, and Pigments, where Black
is the PRESENCE of all and white the absence of all

So at school when they told you Red, Yellow and Blue were the primary
colors... Wrong, primary pigments.. Red, Blue and GREEN are the colors.

The Clapper (TM) normally responds only to sharp loud sounds such as a
clap or a shout, perhaps a bark.. but it has a second setting where most
any sound above a whisper will trip it and turn on the lights.

The "CLICK" of a door closing, or the shuffle of feet on a floor, or the
burgler tripping over the family Rottweiler or... Ok, so if he does
that last one you are not going to need light, the puppy will raise the
burgler's alarm level more than enough to cause his shorts to turn brown
and stinky :)

Cyan is, of course a blue, and Magenta a red,

My point however was school teaches us Red, YELLOW and Blue as primary
colors.. but they are not, they are pigments.

The colors are Red, GREEN and Blue.. Hence the R-G-B connections on many
monitors... Using those three colors and no other you can make most any
color save flesh tone.. Don't ask me why they can not faithfully
reproduce flesh tone,

The point, however, was the difference between pigments, and colors.
The schools tell you "Colors" when they should be saying "Pigments"

There's also the question of subtractive versus additive primary
combinations; I believe CMY is mostly used as a subtractive set.

The difference is in how lights on a theater set handle color vs.
paint and color. One is additive and one is subtractive. Sorry, I
forget which is which.

That was more or less my point Gary... Lights. Screen Phospors and such
are COLORS, they add

Inks and paints are PIGMENTS, and they work differently (As you said
subtractive)

The point is that in school they confuse colors and pigments. Which, as
we have both pointed out, are NOT the same thing.

More accurately, sampling three bell curves. "But the idea's the
important thing." <grin/>

Gary's point about the four-color alien thinking we were partly
colorblind has a direct equivalent here on Earth. Most mammals have only
two-color vision. (From what I've read, reptiles and birds have three
types of color cells, mammals lost one, and primates evolved another to
fill the gap.)

So your furry pet can't see all the colors we can see. And probably
can't see all the stars we can see either; smaller eyes have lower
resolution. (One downside of being reincarnated as a cat.)

Back about 40-50 years ago there was major brand of television (maybe
Magnavox??) that used 4 colors of phosphors to produce their picture
in some of their sets. I'm wondering if it might have been aimed at
making flesh tones look better. I think it was a
red-green-blue-yellow combination. Since it used the same
over-the-air signal, I'm not sure how they decided to stimulate the
4th color phosphors. Or maybe, just maybe it was a holdover from
black-and-white TV days? I seem to recall that the "white" on a B&W
set was actually a mixture of blue and yellow phosphors. So maybe
they used just the RGB phosphors for a color signal and just the BY
phosphors for a B&W signal??

I kind of wonder how this works.. Since the stations only broadcast RGB
they do not broadcast a 4th color. so if you built a 4-color picture
tube..... the 4th color would never activate.

Gamma correction is basically how one maps a digital value to an
output signal. For an analog screen like a CRT, double the voltage =
double the brightness, at least until you reach phosphor saturation.
A digital signal is more complicated. Gamma is a function that maps
digital (DAC VALUES) inputs to screen output.

Generally speaking you want your gamma curve to approximate a log plot
to get the best dynamic contrast.

Maybe that, and not just social conventions, helps explain why the

guy... Nah; if I'm any indication, it's just that unless we're working
specifically with color, guys just don't care about the technical

> But we digress.

Often and enthusiastically.

Bringing this back to music, at least... I wonder whether similar
interpolating of overlapping sensitivies occurs in the auditory system?
If so, that might help explain why we're so fond of specific harmonic
relationships. (I do know that we perceive the appropriate beat
frequencies when different notes are presented to each ear.)

I seem to remember that broadcast analog video (NTSC at least) is
actually a hue/saturation/brightness system, and has to be
translated/decoded anyway... so adding another color should just mean
another channel in the decoder.

Which is one reason different color printers -- or films -- have

Nothing wrong with your memory. and yes, that is all it would take.

However if every television station from Cabot Cove Main (To pick a town
name used in a TV show) to Los Angles (Many TV shows) Is broadcasting
3-color.

What good is a 4th color tube?

The company would have had to set up it's own competing television
stations, which of course would have limited viewers as only their sets
could properly display the 4-color signal. In short. a concept headed
straight to bankruptcy.

Nope. NTSC color was blessed by the FCC. A station couldn't have gotten
a license to broadcast in a competing color standard.

I very strongly suspect you have not clue as to how many different
standards are currently licensed in the assorted and varied radio
services... In fact I"m positive I don't know how many there are and I
have transmitters capable of over half a dozen standards.. Some text,
some audio, some video. Well over half a dozen.

It is very possible to get an experimental license for a new standard.

Strictly speaking, this is called the transfer function.

The gamma is the slope of the transfer function in the mid-tones. The
higher the gamma, the higher the apparent contrast.

The whole photographic chain has a lot of steps in it. In general, you
want a log-log plot of the whole chain to be straight in the midtones,
but with a gradual falloff on the head and toe. How gradual depends on
what you're shooting.

The notion of setting up the monitor is that there should be a standard
curve for all monitors everywhere, so that anything you display will look
the same anywhere and you can therefore select the appropriate curve for
a given image. (Unfortunately the dynamic range of the monitor and of a
piece of paper and of a projected slide are all different, so even with
proper calibration it may look very different in one format than in another.
In the silver photo world we tend to develop an image for a slide to a
somewhat higher gamma than an image that will be printed on paper.)

This is true. Back in the fifties the FCC went through an elaborate
evaluation of various different color systems. The RCA Compatible Color
Method was adapted by the National Television Standards Committee to create
a final standard which the FCC signed off on.

This was back in the days when the FCC actually had technical staff who
knew what they were doing, and administrative staff who believed the spectrum
was like the national parks, a natural resource held in trust for the best
use of the community.

Yes, and if you request a license to operate them on the TV bands, the folks
at the FCC will probably turn you down. Unless, of course you have a vast
amount of money, in which case they will let you do whatever you want. Ronald
Reagan's administration came up with the notion that radio spectrum, rather
than being a natural resource that should be administered for the benefit of
the community, was instead a natural resource that could be exploited for
profit.

Yup, and CBS had an experimental license for their sequential field color
system. The FCC took it away when the NTSC report was published in 1954.
There's a big difference between an experimental license and a broadcast
license.

The FCC, however, started taking a hands-off approach on broadcast standards
with the coming of AM stereo. With this, they basically decided any station
could pick any one of a number of standards, as could any receiver vendor.
The resulting confusion and bungling basically killed AM stereo completely.
Let's hear it for deregulation.

For some unknown reason, my college library had a copy of the book RCA
submitted to the FCC. I think the book was from around 1947 -- the FCC
took a long time to evaluate the proposal. In addition to the specs, the
book had photos of prototype recievers (some with 3 CRTS, color filters,
mirrors, and an extremely limited viewing angle) and the script for test
programming (closed circuit audience tests from NBC studios to nearby NY
city theaters).

FCC and RCA both. For example, there was a bunch of research into color
perception so they could decide how much to filter the "I" and "Q" color
components -- no sense using bandwidth to send extra color detail nobody
would notice. The whole thing was an exercise in getting as much useful
information as possible into a limited amount of bandwidth -- while
keeping the component count down at the reciever end.

You won't catch me slamming those WWII-era engineers.

Couldn't agree more.

And let us not forget that at one time NBC owned the patents for color
television. Which is why Disney broadcast his color television shows
in the early to mid-1950s on NBC.

CBS and ABC took NBC to federal court, and were ordered to share the
technology with CBS and ABC. License fees !

When I was a youth, my employer,
Was a part of that old N.E.T.
And so proud to be a deployer,
(of) Water-cooled COLOR TV.

And on Sundays I'd go to the tower,
To a hut at the end of the road.
Where I read all the meters each hour,
And made sure the diodes still glowed.

Yes, I walked (just a mile) to the station.
In sandals, level both ways.
Through blizzards (this was Minnesota)
Back in those Golden Days...

Back when Fargo was not even Near-go,
And the microwaves ran to Duluth.
And my heroes were Sarnoff and Dolby,
When I was a youth.

When I was a youth, all our networks,
Were simple, and quite low in cost;
We'd load all our tapes on a Greyhound,
(But sometimes a packet got lost.)

And you kids who complain "MTV's cut too slow"...
You don't know how you've got it made.
'Cuz when I was a youth every edit,
Was a slice with brass razor blade.

Yes, I walked (just a mile) to the station.
In sandals, level both ways.
Through blizzzards (this was Minnesota)
Back in those Golden Days...

Back when Austin was not even Aus-zinc
And the telegraph ran to Duluth
And my heroes were Farnsworth and Zworykin
When I was a youth.

We had no I.T. shop like folks do today;
No P.C.s when I was a youth.
And the scarriest thing's every word that I say,
Is the total and absolute truth.

And our stills were all slides in our film chains,
And our credits were rolled on a drum,
And our programs were all aimed at kids' brains,
And old TVs tuned down to "one".

And I walked (just a mile) to the station.
In sandals, level both ways.
Through blizzzzards (this was Minnesota)
Back in those Golden Days...

Back when Brainerd was not even Half-Brainerd,
And not-a-thing ran to Duluth
And my heroes were Ampère and Volta
When I was a youth.

This is true, and because of it some really nice protections were put into
the Communications Act of 1934.

That's not how it worked at all, happily. The goals behind the system were
to encourage diversity of ownership and programming, and they worked pretty
well. In truth, though, the change in the radio industry since the age of
deregulation has been far, far more dramatic than the change in the television
world.

And a lot of this is because the broadcast TV networks are now competing with
cable programmers who are regulated in a very different way.

Though I do feel that the best solution to the dirty word's issue is the
channel changer.. If a network starts showing "The Potty Mouth Hour"
we simply boycott either 1: the show, and if that don't work 2: the network.

Problem is..... That don't happen

Same for comedians... I recall once telling Mr. Roper (Bill Roper for
those who don't know him. Founder, I think, of Dodeka records) how much
I enjoyed a show they did, and epically the fact that they did it
without resorting to dirty words.

Now... Many of today's so called comedians.. I'd be tempted to leave the
comedy club and request a refund, due to their language.

And, as the language on the streets gets harsher and harsher,,,, So does
life on the streets.. Now, I do not know which is cause, and which is
effect. but I suspect disrespectful language, leades to disrespectful
actions as well. In fact, it's a circle with the general lack of
respect leading to higher crime, harsher language, and more disrespect.

So.. Do I feel the FCC is doing a good job of policing our airwaves...
NO, as a matter of fact I don't.

Do I think they need policing.. Yes.

There are several reasons.. One being that the buildings were not up to
today's codes and the second being that the fire departments were not as
"Able" as today's fire departments.

However.. Yes, fires used for both heat and light. often in fire places
that were not up to code or too close to non-flame-resistant cloth. High
on the list.
