Comment Sigh... (Score -1, Offtopic) 632

Yet another reason to be Anonymous in all things.
This is really smarmy and needs to be investigated.

A more fruitful rant might be:
To leave feedback at FB:

"Auto play on mobile is just WRONG.
Mobile bandwidth is expensive and also
costs astounding amounts of battery life.
Just because google+ is worse does not make
it fine. G+ is disabled on my device FB is next."

Comment Re:Great for learning programming, too! (Score 1) 101

I am not thrilled that this is considered a good idea. In principle I suppose you _can_ learn to program on a Chromebook, but only in a very limited way. If this is the wave of the future in education, some thought needs to go into how to design a programming curriculum that can work with these devices.

Not only can but many folk at Google do exactly that.
They interact with the cloud of compute servers and VMs to their hearts content.
It is not necessary but it is possible to set a Chromebook in developer mode
and do the rare odd bit that cannot be done in their cloud. Schools could provide
a modest cloud server set of student resources inside a school VPN and
have a lot of control.

The point is that not only can you but this is solved at Google and with some
modest education of the teachers is easy.

Comment National Security/insecurity (Score 1) 2

Gets a big Hmmm from me.

If an agency is interested in national security and finds a flaw
that has national security implications then exploiting it seems
contrary to the primary charter.

The CIA has an intelligence charter which is slightly different
and to their net goals exploiting it makes sense.

i.e. a security guard that does not get unlocked doors locked
but chooses to slip in an out the door taking what ever is handy
is a thief and criminal.

So what agency has national security key to their charter.
It seems all the agencies have taken on this spy on all
we know what is good for you posture.

This clearly leaves the nation open to industrial espionage
and worse.

Totally wrong.

Where did you see that it was Novec 649? There are a whole bunch of different 'Novec' engineered fluids... They could be referring to Novec 1230, which is a fire suppression fluid [mentioned in TFS]...that one doesn't seem very healthy to be around.

SWAG... scientific wild ass guess.
I looked at the Novec product line and picked on that I would try first.

3M Novec 649 Engineered Fluid

Novec 649 fluid is an advanced heat transfer fluid, balancing customer needs for physical, thermal and electrical properties, with favorable environmental properties. Novec 649 fluid is an effective heat transfer fluid with a boiling point of 49C. Novec 649 fluid is useful in heat transfer particularly where non-flammability or environmental factors are a consideration.

Comment Re:Aiming and targeting? (Score 1) 630

IIRC, the shells will have a guidance system that will allow them to be guided, which is something that they will need if they plan on hitting a moving target – it does take over a minute for the shell to travel 100+ miles – the target will not be in the place where it was when the shell was launched.

And the earth rotates too. Long range gunnery is hard.

Comment Re:"Low Cost" (Score 2) 630

I'll add that I just read that 155mm rounds cost $50,000 each. So it's even cheaper than conventional artillery.

Citation please.

The new GPS radar guided Excalibur perhaps. But no a standard HE round.
  http://en.wikipedia.org/wiki/M...

The max range of a 155 round is a lot shorter than some are indicating.
16000 yards or about 9 miles for the howitzer. It is necessary to
not confuse naval guns with army howitzers. Since I am an Army guy
I will not worry about naval guns beyond acknowledging that "guns" have
longer range but the max is about 23 miles.

Rail guns are interesting as kinetic weapons. The projectile must be
something dense and durable. One guess would be tungsten, or tungsten carbide, depleted
uranium perhaps. Depleted uranium amo is commonly jacketed with gliding metal to protect
the barrel for sure. I wonder if U has sufficient strength as is for a rail gun acceleration profile.

There is a big gap between modern guns ~25 miles and cruise missiles, both range and cost.
Perhaps this is the true goal of a rail gun.

There are fairy glades aplenty in my neighborhood, though I have taken to procuring my wood from a local furniture maker. It dries unromantically in my garage.

Alas, I do not own a fancy CNC router and have learned to make my fiddles by hand, the old way. I will admit to employing a drill press and a band saw in a couple of steps during the process.

Golly you have got to learn to spin a better yarn. ;)

I am told (by experts and makers) that the value of a violin goes up exponentially
with the addition of the sweet harmony contained in the story.

For goodness sake, for fiddles clean the wood or cut a varnish at one step with
a bit of Tennessee whisky or Kentucky moonshine. For a violin audition
them in on a warm summer night with a friend or two out at a nearby glenn .

With the existing data this does not seem to hold up. In populations where it can be measured
in the US there seems to be at best a two year advantage. That alone might be counted
by improvements in pneumonia treatment.

Now the obese generation in their 40s +/- may prove an entirely different set of

balance the scales but obesity is going to hammer quality of life in old age metrics.

Yes and note well that comcast has begun playing games and selling
WiFi connectivity to the likes of AT&T to pump up their bandwidth
failure.

Since Comcast owns the hardware they have started installing modified
software and opening up "guest" accounts that they control.

So far they seem to have taken off some endpoint bandwidth caps
and those that have identified this do not seem to suffer bandwidth losts
HOWEVER you pay for the power and they sell a service.

IMO, If they sell a service that is available 7x24 they should be paying for
AC power and physical plant data closet rates... Sure it is only ---

Comment Poetic license obscures prior art. (Score 1) 1

With the ability to search on the internet there seem to be
a magnification of and concerted efforts to rename almost
anything. Partly from the publish or perish citation world but
with subtle and perhaps sinister financing.

All, that is needed is to cut the research thread is to silently
rename some prior art. And publish in modern documents
and journals.

A RAID might become SyntheticReliableStorageSystem (SRSS).
All papers discussing SRSS would never reference RAID research.
They would bypass RAID and jump to the side for statistical analysis
cited in RAID research iff necessary. All the layers renumbered,
renamed and restructured and Bob is your uncle...

It takes almost a generation but a very strong line is drawn and for
the most part only the grey haired know what went before.
This makes it almost impossible for patent research to reach
back into its own documents and difficult to impossible to
research on the internet or many libraries.

Some companies hire old guys and park them in
a museum like atmosphere and trot them out as needed.
A well fed and well populated museum could be the best defense
from some patent trolls.

Outside of the museum is some serious age discrimination.
