"The techniques that we developed are largely domain independent "

And at 1.35 PFLOPS quite computationally expensive.

But this is pretty impressive

No doubt the Strategic Systems have found some refinements that will be proprietary and lower that or improve the decision making at that level. Of course the human processor does it in 2Kg package that uses about 200W.

Incidentally wasn't improvements to playing "imperfect information" games like poker what the scientist in "War Games" was famous for?

Yes sea trials are to find problems.

"Velocity of the projectile is not the same as capacity,"

True.

I think people think this is like a message pod in a vacuum tube in a building, but for humans. That's simply rubbish. This will need lots of pods together. Since they occupy most of the volume in the pipe pumping down the sections in the stations should be fairly quick.

Likewise people seem to think the pods will need gaps, like the gaps between pods. I'd suggest they run as a package and the pods are the train,with each pod tracking the one in front.

More problematical is the cost. Is this a "mass" transit system, given the massive improvement in travel time? That is more doubtful.

"fastest speed record..red Fiat Panda..four occupants..a dog whilst driven through Dartford Tunnel"

Indeed.

Hyperloop is meant to be fast.

IE multiple Mach numbers.

This is what allows you to stuff a lot more passengers in a lot narrower cars because a)They won't be on them long. At Mach 1 a kilometre is <3 seconds.

London to Birmingham. 126 miles. About 10 mins at Mach 1.

London to Manchester 200 miles About 16 mins at Mach 1.

London to Glasgow 412 miles About 33 mins at Mach 1.

London to Edinburgh 414 miles About 33 mins at Mach 1.

London to Aberdeen 542 miles About 44mins at Mach 1.

Here's the thing.

This has been running 10 years and frankly the BS excuses used to justify it first time round have now been shown to be BS excuses.

My instinct is fail to get to get it re-authorized by year end then re-challenge that "It's still valid till April". If that goes then they have to formally shut it down.

However without effective oversight (and I don't think there has been effective oversight) how can you know if the TLA's have done as they have been told?

As suspected once data fetishists get this sort of capability you may have to pry it out of their cold dead hands to stop them using it.

So who is Kaiser Permanente and what is "Scientific Reports" ?

Turns out they are a company that runs private hospitals, originally founded by a Henry Kaiser, who I'm guessing is the Kaiser in Kaiser Aluminum.

BTW Does anyone recall the studies about increased miscarriage rates of VDU operators in the 80's and 90's?

Apparently it lead to the fitting of Faraday screens in front of the CRT's to block this radiation..

Except it turns out the key stroke recording systems were timing the operators and if you weren't fast, couldn't stay fast or were fast but inaccurate you could be fired, which (surprise surprise) the operators found quite stressful.

So potentially serious if real but as others have noted correlation != causation.

"Strategic Services Group (SSG)"

The "services" provided being to support the "strategy" of

a) Kill all competitors.

b) Destroy any legal obstacles to growing in any market anywhere.

The real model for these guys is the National Cash Register "Hit Squad" to (literally) destroy competition by undercutting their prices, selling poor quality counterfeits to destroy their reputation and steal their IP.

We need to talk about mathematical backdoors in encryption algorithms

John Smith 19 Gold badge
Unhappy

"If you have the plaintext already, you're not looking for a backdoor, "

Not necessarily.

The classic example of a "crib" was the Enigma work where they looked for radio station operators who ended their messages "Heil Hitler."

Then you back convert it to get the settings for the whole message traffic from that site (or "node" in today's packet using world) for the period that code is valid for.

Does anyone doubt such cribs exist today, either due to rules of an organization, or inserted automatically by the transmission software?

Note the argument about the default RSA algo is *not* the same.

It was known (by anyone bothering to check) that the default RSA RNG was less secure than it could be.

The NSA were relying on people trusting RSA to set up the most secure algo by default.

This is not a "Backdoor" in the conventional sense. You don't get a "Magic key" that you run over all the encrypted data and it "magically" decodes.

Instead you get a process that, when given a chunk of encrypted data and the matching plaintext, can cough up the key the rest of the encrypted data, trading a shortish chunk of computation with the ability to bypass any future encryption.

So would a "statistical" test actually find such a weakness to begin with?

His argument is that "absence of evidence is not evidence of absence" and that's true. The question is of course do the TLA's have tools that create apparently secure algorithms which are actually quite vulnerable.

Merry Xmas, fellow code nerds: Avast open-sources decompiler

John Smith 19 Gold badge
Unhappy

"It's possible to leave the..names in a compiled program, for the benefit of debugging tools;"

True.

I wouldn't underestimate the space gained by stripping the executables though.

When you've got a big executable, like the 100 DLLs of an office suite that can make quite a difference in load time, and the ability to respond to user functions.

If they are stripped the de-compile will likely fall back on some default variable naming system. IOW it will be "Pseudo C" (or whatever they modeled their HLL on) with "Fn1" creating "Var1" "Var2," "Var3" etc.

An ability to over ride those defaults can really help when you're gradually working out what the code does a lot easier. It does not change the code logically, but boy does it improve readability.

Sodium-ion technology

Quite an intriguing website.

Especially the graph of element abundance in the Earths upper crust normalized to Silicon (which is pretty abundant)

Sodium is (literally) as cheap as table salt.

Lithium got its jump on other choices because (at some point) a chemist did an energy density calculation. Li is lightest Anode element QED highest density.

But IRL you can't use pure Lithium/Sodium/Calcium and once you start needing high molecular weight polymers in there achievable density starts dropping (but Lithium prices stay the same or rise).

So Lithium is the Gold standard in battery energy density even in "Lithium"

batteries.

Which suggests Sodium might be quite worthwhile.

"Relatively easy != easy."

Exactly. *

Tweaking the recipe slightly. Not too expensive. Junk existing chemistry (and probably production machinery). Very expensive.

Why is the concept of a qualified statement so difficult for people to grasp?

*As opposed to say a Hydrofloric Acid and Cream Cheese battery with an operating temperature of 200c, which I'd suggest has f**k all chance of ever moving outside my head (where it was invented 5 seconds ago).

But if I wanted to do something really clever....

I'd look for a fluid I could run through the cooling jackets of heat engines, or the tubes of a boiler, and then run directly into some kind of flow battery. Turning heat directly into electricity, without generators or alternators.

The chemistries a b**ch and the thermodynamic efficiencies seem low (but I'm not sure why).

Making that work would require very high order boffinery indeed.

Management.

Deciding what tomorrows tasks will be and building the systems to carry them out, possibly eliminating today's tasks altogether.

I'm sure there are many adequate administrators, but few effective managers.
