According to the article, open end tubes resonate at twice their
length, and he says this design is open end.

However, I dabbled a bit in building wooden organ pipes at one time
and if you close the end the note (resonant frequency) drops to 1/2
the open end frequency, so I suspect he may have some facts wrong.
Assuming his design works, and I trust it does, it may be acting like
a closed tube, so electrets would work fine without changing the tube
length.

We had a system that used football stadium size antennas with phased

goniometer to rotate/steer the beam direction. Then some pointy head
figured out how to do the same thing with a single monopole antenna.

Samsung's decision to halt sales of the new Galaxy Note 7 because of
reports of battery explosions is an extraordinary step for a tech giant
to take.

The firm said it had identified a battery issue but did not elaborate.

But if a lithium-ion battery cell charges too quickly or a tiny
manufacturing error slips through the net it can result in a short
circuit - which can lead to fire.

One expert urged the industry to find safer alternatives to lithium.

"I think one should be concerned and push towards safer battery tech,"
said energy storage expert Professor Clare Grey from Cambridge University..

"That should be an important focus on research and industry development.

"While most manufacturing flaws will be picked up during initial
testing, it's not an infallible process."

However Prof Grey also said that people should not panic.

"I'm standing at an airport - every single person would have to stop
what they are doing if we took their batteries away from them," she said.

"We all take risks in our lives - we drive cars sitting on top of
flammable organic liquids. Other tech is coming along that is safer."
Common causes

There have only been 35 cases of the Galaxy Note 7 catching fire
reported worldwide following 2.5 million sales, Samsung says.

The lithium ion batteries used by Samsung are common across the tech
industry - so what makes them hazardous?

It's important to understand a little about how they work. Simply they
contain a cathode, an anode and lithium.

The cathode and anode are separated by an organic liquid called an
electrolyte and a porous material called the separator.

The lithium travels through the separator, within the liquid, between
the two.
Quick charge

If the battery charges too fast, generating heat, lithium plates form
around the anode which can create a short circuit.

"Normally you would have a battery management system that controls the
rate at which you charge," said Prof Grey.

"Batteries are optimised so that you don't charge too fast - if you do
that you will plate the lithium."

This is also why battery charging can be a frustratingly slow
experience, she added.

Other faults that can cause a short circuit include contamination by
tiny fragments of metal during the production process or minute holes in
the sealing, which might not become apparent until the battery has been
charged a few times as the materials expand and contract.

"The manufacturing has got a lot more standardised than it was 10 to 15
years ago," said Prof Grey.

However battery packs - combining battery cells to generate more power -
can be problematic and this is increasingly common. Batteries containing
12 cells, for example, are readily available for laptops.

"The more you put together, the higher the likelihood that some will
fail," she added.

"There are still flaws emerging but it's getting better. It is a
challenge - with so many being produced, you just need one error."
Signs to watch out for

There can be symptoms indicating that a battery is about to fail, said
support and repairs provider Geek Squad.

"Sometimes, a battery will start to swell and bulge before it fails
completely, as the internal cells rupture and break," it says on its
website.

"But the bulge doesn't always happen. If not, you might notice that your
device is a little warmer than usual - but let's be honest, our phones
get fairly warm during standard usage anyway."

The firm suggests disposing of any batteries displaying these signs.

There was a nice article on the history of Li batteries in this months Physics Today,

http://scitation.aip.org/content/aip/magazine/physicstoday/article/69/9/10.1063/PT.3.3296

Short answer, the organic electrolyte can burn.
From article.
"In such circumstances, the organic electrolyte can ignite and the battery effectively becomes an incendiary."

35 / 2.5 million = very small number.

True, but you do tend to expect better especially when you lay out
6-700 bucks for one. The recall is the right move IMO.

Looking at getting Spectrum cable but having spec difficulty.

They will provide a router only, router with wifi or router with wifi
and phone but cannot give me specs.

What's my problem ?
I currently have AT&T WiFi Router that does not have much power out and
seems to drop WiFI or internet or ??? often. My security cams turn off
and the app shuts down. Bad app too !

If I use WiFi Analytics WiFi app on my laptop it shows the AT&T WiFI at
"Max Rate" 150 where another LAN WIFi router at the other end of the
house shows as "Max Rate" 300. I cannot watch movies from the back
room PC where the AT&T WiFi is to the living room PC using their wifi
since it stops and stutters. Using a cable down the hall works perfectly..

Several questions.
What feature should I be looking for in a WiFi router:
Speed 300 vs 150 "Max Rate"
Power output
Dual freq 2.9 vs 5 GHz
AC protocol or whatever it is called

Spectrum says it installs an Arris TG1672G but it does not specify
output power in the specs I found. Anyone have a better spec source ?
I am not even sure that is the WiFi modem router that I will get as it
seems they grab whatever is handy to bring out to install.

So I hate to think I would have to set up my own WiFi Router.

Last question -
If I get internet only and want phone service, what are my choices ?
And would that service be able to take my current land line phone
number and use it ? I would totally drop AT&T if so.
Does that service have caller ID - mandatory feature for me to have.

Also is there a preferred Channel ? 1 or 6 or 11 or ???

--- news://freenews.netfront.net/ - complaints: news@netfront.net ---

I use a cable modem (Comcast) to router (D-Link) with WIFI but wired to PC (approx 75Meg thru-put from Comcast). Two people in house with cell phones on two different networks so we only lose it if both networks goes down. Has worked for 4 years with no total lose of service as of yet except when inept city workers tear down cable line with a knuckle boom (twice in 5 months).

If I remember correctly, there are more ways of winning if you start in
the corner (the proof is simply by counting games) and, since you can't
be forced to lose if you start there, you could argue that you might as
well do that.

If you start in the middle there are fewer games that you can win, but
it's also easier to see that you can't be forced to loose and I suspect
it's that which leads people to chose the middle.

By the way, why the cross post to alt.conspiracy? Do you want to be

If no one makes a mistake the game will always end in a draw.

There are certain ways to start off that may let you win if the other
player does not know the game very well.

Playing the game against people is very different from playing it
against a computer. You won't fool a well-written program, but people
can be suckered into losing. And the first rule of suckering people is
to start in a corner. If you start in the middle, they'll pretty well
know how to force a draw. But if you start in a corner, they're less
likely to correctly select a safe move. Of course it's impossible to
demonstrate this over Usenet, especially to programmers, because nobody
is going to post a move without analysing it to death first. But in the
real world, people don't do that. They know it's a forced draw, they
assume they can't lose, and they play carelessly --- and then they don't
understand why they lost.

I worked out every possible move when I was a kid.

If your first move is in the center, the other player can force a draw
no matter where his second move is.

If your first move is in the corner, the other player can force a draw
if his second move is in the center, but if his second move is anywhere
else you can force a win.

There is no draw nor peace? ;)

That depends on how the player program was written. Tic-tac-toe does NOT
have too many combinations and matrix of moves. Putting them all in a
database, and the computer program could just follow the pattern to make
a draw.

So it's theoretically possible to "personalize" the program so that it
is playing like a real human.

Perhaps you don't read too well, but it has already been explained that
it is futile to attempt to demonstrate the human psychology of the game
over Usenet, especially in a technical group, where people will
inevitably analyse the state of the game before every article they post.
People /don't/ do this when playing the game face-to-face.
