OpenBSD Team Cleaning Up OpenSSL

AnotherBlackHat Re:What about a re-implementation... (288 comments)

While it might be nice to use a safe(r) language, can't we at least have a compile option in C that adds bounds checking?

And while you're at it, how about making it impossible to execute code that isn't in the code segment and write protecting the code segment.

The 3D Economy — What Happens When Everyone Prints Their Own Shoes?

AnotherBlackHat Food printers (400 comments)

There's an amazing technology called "seeds".
These "seeds" grow into actual, eatable food.
Even better, they're solar powered and the feedstock is water.
And to top it off, one of the things these "seed" machines can manufacture is more seeds!

Thanks to this technology, the future will be filled with people who grow their own food, and things like supermarkets will become a relic of the past.

NSA and GHCQ Employing Shills To Poison Web Forum Discourse

AnotherBlackHat Re:The slides... (347 comments)

A slashdot sock puppet could follow the classic ideas in "The Gentleperson's Guide To Forum Spies (spooks, feds, etc.)"

Slashdot moderation makes it a lot harder. For example, off topic rants are down modded to oblivion, and the structure of the reply tree make forum sliding much more difficult.
It would be far easier for the NSA to destroy Slashdot by buying it, then changing the way the forum works.

LA Times: Snowden Had 3 Helpers Inside NSA

AnotherBlackHat Scapegoats must be found! (148 comments)

Unable to put Snowden on trial, the NSA has decided to sacrifice three other employees.

I look forward to the circus of their trial, I hear they'll be serving bread.

Will Electric Cars and Solar Power Make Gasoline and Utilities Obsolete?

AnotherBlackHat Re:Fine. Let's have "Oranges vs. Orange equivalent (734 comments)

>Okay, compare a contemporary battery...

No, that's precisely my point - don't compare a tiny subsystem of the car and pretend that's the whole problem.

It's not just the fuel, or the fuel plus the fuel tank.
It's the fuel, the tank, the engine, the wheels, the cooling system, the exhaust system - basically everything.

Will Electric Cars and Solar Power Make Gasoline and Utilities Obsolete?

AnotherBlackHat Apples vs. Oranges. (734 comments)

Gasoline is a fuel.
Batteries store fuel (electricity).
Batteries are roughly comparable to gas tanks, not gasoline.

If for some reason you just want to only compare the fuels, compare gasoline to electricity.
One gram of electricity is more energy than you get from One tonne of gasoline. It's about 9 orders of magnitude better, energy density wise.
It's a completely bogus comparison too, but it at least it is more sensational.

For a fair comparison, compare the weight of everything it takes to make the wheels turn;
The gas, the engine, the cooling system/radiator, tail pipe and muffler, drive train, air filter, and so on, with everything on an electric car.

Candy Crush Maker King.com Has Trademarked 'Candy' For Games

AnotherBlackHat Can we please sue these idiots? (169 comments)

No, not the idiots who trademarked "candy", the idiots who let them trademark candy.
As in, sue the people in the trademark office that approved an obviously flawed trademark, and force them to make restitution to the public.

NYC's 250,000 Street Lights To Be Replaced With LEDs By 2017

AnotherBlackHat Re:Aren't HPS lights more efficient than LED? (372 comments)

High Pressure Sodium street lights are around 100 lumens per watt. HPS can be as low as 50 or as high as 150 depending various factors.
LED street lights are also around 100 lumens per watt, but they vary even more widely.
A theoretically perfect light source with a wavelength of 555 nm would emit 683 lumens per watt, so both LED and HPS are about 15% efficient.

Even the best HPS is less than 25% efficient, and the best LED isn't much better at just over 35%.
At 14.5 lumens per watt, an A19 incandescent 60 Watt bulb (i.e. a "normal" bulb) comes the closest to 97%, but it's 97% inefficient.

NYC's 250,000 Street Lights To Be Replaced With LEDs By 2017

AnotherBlackHat LED street lights are over 100 lumens / watt. (372 comments)

Yes, it's you - you are so last year.

We aren't talking about those cheap $10 bulbs from Home Depot that get a measly 84 lumens/watt.

Commercially available LED street lights like Cree's LEDway have been over 100 lumens / watt since 2013-03, making them more efficient than high pressure sodium even without considering their arguably superior focusing and CRI.

Two-Laser Boron Fusion Lights the Way To Radiation-Free Energy

AnotherBlackHat Re:Hooray for fusion! (140 comments)

If I'm crunching the numbers correctly, 1 gram of Boron produces 25,000 kWh of electricity - assuming perfect capture, 100% boron-11 and no other loses. (Granted, all unrealistic assumptions, but it's a starting point.)

If we replaced all electric generation on the planet (about 20 trillion kWh / year) it would take 800 tonnes of boron per year.

Turkey has the largest known Boron deposits at over a million tonnes or 1,200 years worth. And there are several other countries with large (thousands of tonnes) deposits as well, and that's just the Boron we know about.

All really rough estimates, but I don't think will run out of Boron fuel any time soon.

Why Steve Albini Still Prefers Analog Tape

AnotherBlackHat Tape? Sure. (440 comments)

You want to give me a master copy on tape? Great!
I wouldn't say no to CD either, and pretty much any other format or media.

Just be sure there's at least one a digital copy in a lossless DRM free format included in the pile of copies you're giving me.

When Writing, How Anonymous Can You Be, Really?

AnotherBlackHat Re:Authors can use these tools too. (184 comments)

What would be the point of mutating the way you write so that you can no longer be identified ...

If you are writing characters for a story, you might want them all to have unique, easily identifiable speech patterns.

Also the traits that stand out and identify you most are probably really annoying.
You might want want to reduce them.
For example, you might want to not use the phrase "might want" nearly so much if it was brought to your attention.

Researchers Create New Cheap, Shatterproof, Plastic Light Bulbs

AnotherBlackHat Lumens per watt? (296 comments)

A "normal" A19 soft white bulb is about 14.5 Lumens per Watt.
A typical CFL is around 55 Lumens per Watt
A good LED bulb is around 90 Lumens per Watt (and they're getting better)

Fipel bulbs are "Highly Efficient".
Anyone have an idea what that is in Lumens per Watt?

Red Hat Developer Demands Competitor's Source Code

AnotherBlackHat How can you "violate" the GPL? (394 comments)

If you don't comply with the GPL, than at most, you are violating copyright law.
Following the GPL is optional. It grants you certain rights if you follow it.
You might have those rights anyway, or you might decide it's better to pay the fines for copyright violation, but I don't see how you can be forced to follow the GPL.

NetFlix Caught Stealing DivX Subtitles From Finnish Pirates

AnotherBlackHat Re:Stealing subtitles? (284 comments)

That's what I was thinking. Technically, the copyright owner owns the rights to derivative works.

In the sense that you need their permission, yes.
But the original creator does not own all the rights - you will also need the permission of those that created the derivative.
You have to satisfy both of them to publish legally.

Sugar Batteries Could Store 20% More Energy Than Li-Ions

AnotherBlackHat Uh ... No. (152 comments)

First, regarding the so-called sugar battery;
It's really a sodium-ion battery.
They claim a 20% increase in power storage over a lithium-ion, which probably means a 20% decrease in cost, best case.
Sodium-ion batteries have cycle problems - after about 50 charge/discharges, they typically have 50% of their original capacity. They don't even talk about this, so I'm betting they haven't solved the problem.

Second, about lithium-ion batteries;
Lithium isn't rare - you could extract it from sea water for about 3 times what it costs now. Even at that price it wouldn't mean much to lithium-ion batteries, because despite the name, lithium isn't the primary ingredient, nor is it the most costly.

Envia's breakthrough battery is a lot better at 3 times the energy density and half the cost, and it's a lot closer to market.

ACLU Questions Privacy of License Plate Scanners

AnotherBlackHat Re:Where is the line? (246 comments)

Anyone can sit down and write down liscense plate numbers.

And in theory you could hire an army of people to stand on every corner and record every license plate they see - and that would be an invasion of privacy.

The problem isn't the scanners. That's how they keep tabs on everybody's movements. The problem is that they think it's OK to keep tabs on everybody's movement.

Joseph Palaia Answers Your Questions About Building Lunar Machines and Mars

AnotherBlackHat Re:Nitrogen... (63 comments)

as far as I understand it, there really isn't a good source of nitrogen on mars (atmosphere 95% CO2, 3% N2 on mars, vs 78% N2 and 20% O2 on earth).

The atmosphere of Mars may only be 3% nitrogen, and only .6% the density of Earth, but it's still a lot in absolute terms.
Easy to get, and unlikely to run out.

With a reactors worth of energy and maybe a tonne of compressor, it's reasonable to liquify and separate it into CO2, Nitrogen, Argon, and water.
My very rough estimates are about 10kWh to produce one kg of liquid nitrogen (about 1m^3 worth of 100kPa air).
A decent sized habitat has maybe 200m^3 of air.
A megawatt power plant, and you could fill that in less than a day.

Bas Lansdorp Answers Your Questions About Going to Mars

AnotherBlackHat Re:DIscussed the business case with media partners (189 comments)

The first moon landing was watched by an estimated 600 million people.
The Olympic games are watched by an estimated 3.2 billion.
Sure, a lot of people would watch the first manned Mars mission, but the case for "more people watching than watch the Olympics" is still weak.

Think how many SciFi shows have been canceled because they cost too much to produce. Now consider that "too much" is still less than 100 million a year, or about 1.6% of six billion.
