The One Mistake Google Keeps Making

AnotherBlackHat Driverless trucks (386 comments)

Truck drivers get over $40k a year, and they don't drive 24/7.
I'd bet a trucking company would pay a lot for a driver-less truck, even if it could only travel a few routes.

New Proposed Path for Manned Trips to Mars: Let Mars' Gravity Capture Spacecraft

Minor quibble - instead of water, you send hydrogen, only takes 1/8 of a tonne.

Vinyl Record Pressing Plants Struggle To Keep Up With Demand

AnotherBlackHat Re:Nitche Market (433 comments)

Are you really trying to claim that;
a. The only possible way to reduce the dynamic range on a vinyl record is to reduce duration, and
b. No one would ever sacrifice duration to make things louder?
I take issue with both statements.

Vinyl Record Pressing Plants Struggle To Keep Up With Demand

AnotherBlackHat Re:Nitche Market (433 comments)

The loudness wars started long before CDs.
It's prevalence has more to do with how music is produced than with the format it's recorded on - i.e. it's easier today to over compress something than it used to be.
If vinyl was still successful, there would be just as many over compressed piece of shit vinyl records as there are over compressed piece of shit CDs.

The Failed Economics of Our Software Commons

AnotherBlackHat Quis custodiet ipsos custodes? (205 comments)

When money is involved, the question that comes to mind is "who should be in charge?"
There's a surprisingly consistent answer to this question.
I hear it a lot, from a lot of different people and that answer is "I should".

Snowdrift describes a way to raise funds.
It might even be more effective at raising funds.
But I see nothing that promotes spending those funds wisely.

Multiple Manufacturers Push Hydrogen Fuel Cell Cars, But Can They Catch Tesla?

AnotherBlackHat Re:next gen batteries (293 comments)

If you're going to compare that way, you need to factor the relative efficiencies of the two fuels -
electricity can be converted into kilometers about 3.5 times as effectively as petrol can.

Rule of thumb; Electric cars get 5 km to the kWh
500 kW watts for 10 minutes = 83 kWh = 400 km = 250 miles

But really, who cares which is faster, which do you think about first when deciding what car to buy;
Fuel economy, price, style, carrying capacity, cost of maintenance, or speed of fill up?

Charging doesn't have to be fast, it just needs to be fast enough.

For most people, electric cars can be charged at home overnight.
It may be a longer overall time, but it's a lot less of my time (a few seconds to plug in vs. a few minutes to fill up).
For long drives, a diner/charging station would work fine. Thirty minutes to eat and charge.

In a Self-Driving Future, We May Not Even Want To Own Cars

AnotherBlackHat Taxis - The Self Driving Car of Today (454 comments)

We have a "self driving" car technology, it's called a "taxi", and millions of people use them and avoid buying a car already.
Most of us avoid these due to a thing I like to call "being rich enough not to have to put up with that shit".

I own a car because I don't want to share.
That's not going to change if the car can drive itself.

First Detailed Data Analysis Shows Exactly How Comcast Jammed Netflix

AnotherBlackHat Re:Yes it is a peering problem ... (243 comments)

Settlement free peering between tier 1 carriers only happens when the flow of traffic is roughly balanced between the contracting peers.

When one peer is pushing a lot more traffic onto the other network, then that usually goes out the window and the pusher is required to pay the receiving network.

So you're saying if Netflix downloaded more data from Comcast than they sent, that Comcast should pay them?

I have no problem uploading an amount equal to what I download from Netflix, or even more, if you really think that will solve the problem. I don't really control the software on my Roku box, but I don't mind if Netflix puts some P2P software on it for help carrying their own traffic.

Ask Slashdot: How Would You Build a Home Network To Fully Utilize Google Fiber?

AnotherBlackHat Two Rules (279 comments)

I've found two rules to be very helpful when dealing with this sort of problem;

1. Don't buy it until you need it.
        Electronics in general are going to be cheaper, faster, and smaller in the future, so put off all buying of stuff as long as it's reasonable to do so.

2. When you need it, buy it without hesitation.
        If the current best solution is X, then pay for X and don't worry about it. Yes, there's a better way, and yes, there's going to be an even better way in the future, and yes X is going to suck in 10 years. But there's no way to avoid that so don't sweat it.

You have Google fiber. You have a 600Mbps solution to connect to that fiber. Do you need more than that, right now?
If not then apply rule 1, and do nothing. If so, then apply rule 2 and wire your house with Cat6 (or pay someone else to do it.)

Adobe Spies On Users' eBook Libraries

AnotherBlackHat Re:Time for some crapflooding. (150 comments)

Injection attacks or other unsanitized data.
Material that you (or Disney) hold the copyright to.
Anything illegal to export/import (nuclear secrets, cryptography)
Sensitive personal information of important people.
Any information Homeland has forbidden you from discussing.
Even just the simple volume of the material could be a problem. (Of course the list of my ebooks is 24 terabytes, why how big is yours?)

The list of things they can get into trouble just having a copy of is almost endless.

Adobe Spies On Users' eBook Libraries

AnotherBlackHat Time for some crapflooding. (150 comments)

If Digital Editions, or any other program, is sending meta-data about the contents of hard drives, then they deserve to what they get.

I picture a small program that creates millions of pseudo-random file names ending with .epub, .pdf, or whatever else D.E. is scanning for.
I'd certainly be willing to dedicate a few gig to the task, I'm sure there are several thousand others who feel the same.

Solar Plant Sets Birds On Fire As They Fly Overhead

AnotherBlackHat Re:Drop solar heat for direct conversion (521 comments)

Except you can not exceed the solar power that hits the surface of the planet from the sun.

There are actual, serious, plans to put solar in orbit. Solar isn't limited to the surface of the planet.

But let's ignore that power-in-sky thinking for a moment.
The amount of sunlight that hits the Earth is an astronomical 150,000,000,000,000,000 Watts.
That's around 1000 times man's total energy usage.

To put it in per capita terms;
At noon, 1 square meter on the surface receives about 1 kilowatt of energy.
The average over a day is 4 kilowatt hours per square meter.
A typical home is 100 square meters, and uses 24 kilowatt hours a day.
At 12% efficiency, you only need to cover half the roof with photovoltaics to supply 100% of that homes electric needs.

Companies That Don't Understand Engineers Don't Respect Engineers

AnotherBlackHat Re:us other engineers matter, too (371 comments)

Valuing people by their number of direct or indirect reports makes a lot of sense. If I am one of a group of ten people and I'm 20% more productive than the others, my extra contribution only adds about 2% to the total. If I am a good manager my staff might be 5% more productive than an average manager's.

If you're good you should be in charge of more people, but being in charge of more people doesn't make you good.
Or to put it another way, just because a position is important doesn't mean the person in the position is.

Mass. Supreme Court Says Defendant Can Be Compelled To Decrypt Data

AnotherBlackHat Damned if you do. (560 comments)

"We know you did it, so until you confess, we're going to hold you in contempt of court."

The court is claiming that they really, truly, pinky swear know he did it, because they heard him say so, so that whole "can't force you to testify against yourself" thing doesn't apply.

I don't believe the spirit of the 5th is that it doesn't apply when we know you're guilty.

Cable Boxes Are the 2nd Biggest Energy Users In Many Homes

AnotherBlackHat Math is hard. (394 comments)

A typical set-top cable box with a digital recorder can consume as much as 35 watts of power, costing about $8 a month for a typical Southern California consumer.

A "typical Southern California consumer" pays less than 20 cents per kWh.

35 Watts * 24 hours/day * 30 days/month = 25,200 Watt hours or 25 Kilowatt hours.
25 Kilowatts * $0.20/Kilowatt hour = $5.00

Imparting Malware Resistance With a Randomizing Compiler

AnotherBlackHat It won't help (enough) (125 comments)

Viruses in nature mutate randomly. Computer viruses don't.
Computer virus designers are intelligent, hostile, and evil in intent.
If there's a way around it, they'll find it and it's game over.

Besides, many if not most attack vectors wouldn't care a whit - tricking a user into executing code would still work, SQL injection, cross site scripting...

Mental Illness Reduces Lifespan As Much as Smoking

Syphilis drives you crazy, and then kills you. It doesn't kill you and then drive you crazy.
Any disease or genetic condition which slowly kills you is likely to make you depressed first.

Is LG's New Ultra Widescreen Display Better Than "Normal" 4K?

AnotherBlackHat Betteridge said it best: No. (304 comments)

First of all, 3440x1440 isn't better than 3840x2160.
If you really truly believe that a 21.5 aspect ratio is better than a 16:9, you could put a piece of tape over the bottom 500 lines of a "standard" 4k display and still end up with a higher res.

How about building a display panel that doesn't have edges?
Give me a dozen megapixel panels and a let me arrange them however I like.
Make them modular, interchangeable, cheap, and the whole display becomes expandable.
Or improve the power efficiency, or the cabling, or the weight, or the color depth, or... any of a dozen other things I care about more than the aspect ratio of a single panel.

If you absolutely must claim that one aspect ratio is superior to another, then why not go with the golden ratio?
At least that way you can put two together and still have the same ratio.
