The Pentagon's $399 Billion Plane To Nowhere

inhuman_4 Re:More F-35 Hate (364 comments)

Sorry you feel that way. But if you look at my account I've been active since 2009, rather dedicated for an astroturfing account.

The truth is the track record on the F-35 is little different than any other post-cold war weapons program. They are always over budget and behind schedule.

F-22: Too slow, no air to ground, too expensive, stealth not proven, too little armament, no competitor for it to face, cold war relic, etc. Orders dropped from 750 to 195. Now people are proposing to buy more of them instead of the F-35.

B-2: Stealth not proven, too slow, too expensive, hangar queen, poor handling, etc. Orders dropped from 132 to 21. Now it's heralded as a sign of American military power.

Elements of Power: http://elementsofpower.blogspot.ca/2013/08/f-35-critics-same-sht-different-century.html Does a great job comparing the complaints about the F-35 to complaints made about the F-15.

It's always the same nonsense, complaining about specs that don't matter in modern combat, ignoring improvements to things that do matter, offering no alternative, complain about cost.

The Pentagon's $399 Billion Plane To Nowhere

inhuman_4 More F-35 Hate (364 comments)

Ah yes more F-35 hate.

Claim the costs are increasing, except the price per plane is decreasing. Check.

Faux outrage at the $1 trillion price tag that has been part of the plan for decades and pays for R&D for 3 new fighters, a purchase order for ~2,500 aircraft, plus maintenance and training for 55 years. Check.

Complain that it has a part built in every state, just like every other military project in the last 50 years. Check.

Unfortunately the authors forgot to mention how important dog fighting is to a strike fighter. Also passed up the opportunity to talk about how we are not sure if stealth actually works. I mean, the least they could do is compare it to the F-16 using clean specs and a non-inflation adjusted price from the 80s.

Standard cheap-shots on the costs, but weak follow through on "manoeuvrability problems". I'll give it a 6/10.

The Internet's Own Boy

inhuman_4 Re:His choices... (194 comments)

For sure he made some poor choices.

But that doesn't excuse the government response. The justice department had no reason to act in such a heavy handed manner. They quite clearly wanted to make an example of him and were willing to bend the law to do so.

But the bigger issue here isn't Swartz, it's the fact that this kind of treatment has become common place. Putting a "hacker" in solitary confinement didn't make any sense when they did it to Kevin Mitnik, and it didn't make any sense with Swartz. It's an abuse of power, the tragedy is it took a suicide for people to notice.

The Government Can No Longer Track Your Cell Phone Without a Warrant

inhuman_4 Just can't use it in court (173 comments)

The key take away is that they can no longer use this information as evidence in court. The government will still use this information to track you; but they will need to get more creative when they do parallel reconstruction.

Mutant Registration vs. Vaccine Registration

inhuman_4 We don't do this already? (493 comments)

As a Canadian I'm shocked that the government doesn't already do this. I alway just assumed that when I went to the hospital the medical staff could look up what shots I've had, what I'm allergic to, and any major surgeries I've undergone.

As a side note. I think this a good idea. I sure as shit don't want someone who isn't vacinated wandering around a hospital war full of people who's immune system is compromised.

AT&T Hacker 'weev' Demands One Bitcoin For Each Hour He Spent In Jail

inhuman_4 I hope that he gets his money (449 comments)

I hope he gets everything that he asks for.

Yes the Timothy McVeigh, Andrew Stack, and Marvin Heemeyer part was in very poor taste. Yes his "open letter" is childish.

I don't care. The government doesn't get to abuse someones rights, no matter how much of an asshole that person may be.

NASA, France Skeptical of SpaceX Reusable Rocket Project

inhuman_4 Re:Space Shuttle Challenger (333 comments)

The thing is there is a huge difference in what "reuseable" means for the Space Shuttle and for the Falcon.

The Space Shuttle was firing the engines for 540-761 seconds, taking the engines to orbit , staying in order for days or weeks, bringing the engines back through reentry, then refurbishing them. That is a pretty tall order.

SpaceX is only trying to recover the first stage. It only burns for 180 seconds. Reaching a maximum height of around 90-100km (about the same as SpaceShipOne). Since it never reaches orbital velocity it doesn't experiance anything like the reentry forces the Space Shuttle does. It then does a powered landing on a launch pad. Still a tall order, but much less than what the Space Shuttle was trying to do.

Additionally the Falcon 9 has already demonstrated that it can complete is primary mission with one engine failure. And the resuable engines will not be used on man rated systems, so the reliability standards are not as high as for the SSME. We won't know how extensive the refurbisment costs are, but the Merlin engines are smaller and simpler than the SSME. Its possible that some of the 9 engines may have to be discarded, but even if only 5-6 are in good enough shape to be resued in non-man-rated launches; that is a pretty significant cost savings.

Commenters To Dropbox CEO: Houston, We Have a Problem

inhuman_4 Change of tune (448 comments)

I find it very amusing how the tune has changed with regards to how vote with their wallet and corporate moral character.

For the longest time the argument was "Well if you don't like company x don't buy their products!". With the implication being that if you don't actually stop, then you are just a whiner or a hypocrite. But now people really are taking their business elsewhere. The actions of a company or the people that represent a company is effecting the bottom line. Yet somehow old "vote with your wallet" is no longer acceptable. Somehow judging a company based on it's moral character is an assault on free speech, maybe even down right persecution!

For a long time people (on Slashdot especially) have been warning of the dangers of putting your data in the cloud. Of the amount of personal information that can be gleaned from your web browsing habits. That that big business is cooperating with the government (willingly or not) in a massive breach of privacy. So how and can anyone be surprised that customers demand moral character from leadership of companies to whom we are handing over so much personal information?

If you had to make a choice between companies to store YOUR personal information and your choices are: Company A with Bruce Schneier on it's board of directors, and Company B with Dick Cheney on it's board of directors. Does anyone seriously think that difference shouldn't effect the decision?

I for one have no sympathy. Yes a company has every right to alienate their customers, but customers also have every right to vote with their wallets.

A Rock Paper Scissors Brainteaser

inhuman_4 Re:Simple.... Odds are even (167 comments)

If you play 2/3 paper 1/3 rock. He will play 1/2 paper, 1/2 rock.

Wins for you:
Paper vs rock: 2/3 * 1/2 = 1/3 win
Rock vs scissors: 1/3 * 0 = 0 win
Scissors vs paper: 0 * 1/2 = 0 win

For him:
Paper vs rock: 1/2 * 1/3 = 1/6
Rock vs scissors: 1/2 * 0 = 0
Scissors vs paper: 0 * 2/3 = 0

Your optimal strategy (2/3 paper, 1/3 rock) vs his optimal strategy (1/2 paper, 1/2 rock), results 1/3 win not a 1/2 win.

A Rock Paper Scissors Brainteaser

inhuman_4 Re:Two Games (167 comments)

We know that the opponent must play rock 1/2 of the time.

If I play paper 4/6 of the time, than I should expect 1/2 of my paper to align with his rock. So 4/6 * 1/2 = 2/6 = 1/3. So I should expect to win 1/3 of the time, plus my winnings on the other combinations. That means 1/3 is the lower bound.

If you play 1/3 rock and 2/3 paper, his response will be 1/2 paper and 1/2 rock. So you are going to get 2/3 * 1/2 = 1/3 for your paper. But your 1/3 rock will never win because he will never play scissors either. But his 1/2 paper will meet your 1/3 rock, giving him 1/2 * 1/3 = 1/6 win. Putting you head by only 1/6.

This is where the two games key comes in. You and I both recognize that 2/3 paper is the right move because 1/2 of his moves will be rock. But by playing the other half as regular RPS with a win/tie/loss of 1/1/1 you can expect the win/loss to cancel out, leaving you with your 1/3 lower bound advantage.

A Rock Paper Scissors Brainteaser

inhuman_4 Re:Two Games (167 comments)

The opponent doesn't have the option to play anything greater than 1/2 scissors because the other 1/2 must be rock. If he uses the "all scissors" response, he can only actually do a 1/2 scissors response. So is we play it out:

1/2 scissors x 4/6 paper = 2/6 = 1/3 victory for the opponent. 1/2 scissors x 1/6 scissors is 1/12 tie. And 1/2 scissors x 1/6 rock is 1/12 lose. So the "all scissors" strategy only nets him 1/3 victory not 4/6.

A Rock Paper Scissors Brainteaser

inhuman_4 Two Games (167 comments)

You should play paper 4/6 of the time, rock 1/6, and scissors 1/6 of the time.

The key (if you RFTA) is that whether or not your opponent plays rock is determined by a coin toss. So really you are playing a compound game. You are playing a coin toss and rock paper scissors (RPS). Since the coin toss determines your opponents move, you can think of it as playing 50% coin toss and 50% RPS. The RPS is a subgame of the coin toss.

Since the coin toss is the dominate game, you play with win that first. But instead of heads/tails, it is paper/other. The answer to the coin toss is a 50/50 guess of heads/tails, so the answer to the paper/other is 50% paper, 50% other.

The "other" is the RPS game. And since the answer to the RPS game is 1/3 rock, 1/3 paper, 1/3 scissors, we know what the solution to the other 50% of the game is.

So the equations are:choice = (Coin Toss) + (RPS) so: paper = 1/2 + 1/3, rock = 0 + 1/3, scissors = 0 + 1/3. Or paper = 4/6, rock = 1/6, scissors = 1/6.

oVirt 3.4 Means Management, VMs Can Live On the Same Machine

inhuman_4 Re:Still trying to wrap my head... (51 comments)

One big issue is that virtual machines allows for different OSes. So if you are provides a variety of services, like legacy applications for example, you consolidate them all on to one machine.

It also allows for easier testing. Say for example you need to stress test your application on some combination Red Hat, SUSE, Debian, FreeBSD, WinServer, Mac, and Solaris, or even a variety of different versions of those OSes. Putting them all in virtual machines is much simpler than re-installing or having a dedicated machine for each one. It also makes it easy to call up your test environment if a customer reports a bug.

Sulfur Polymers Could Enable Long-Lasting, High-Capacity Batteries

inhuman_4 Re:Still a ways to go (131 comments)

Aircraft are very sensitive to the weight. But ships are not. I wonder if it would be realistic to have a battery powered ship for cross ocean voyages. Especially for things like tankers and cargo ships. Pull into port and get hooked up with special massive power tx lines and fill up the battery.

I seem to recall that large ships are a big source of CO2 emissions. If it is possible I wonder what the trade off is in terms of costs.

NRC Expects Applications To Operate Reactors Beyond 60 Years

inhuman_4 Re:Idiots in power (135 comments)

Exception, after exception isn't being made. It made headlines for weeks. Then it had to go all the way to parliament to get an exception made. And even then is was only for a short term exemption until a proper solution to the shortage could be found.

NRC Expects Applications To Operate Reactors Beyond 60 Years

inhuman_4 Re:Idiots in power (135 comments)

The Chalk River medical isotope issue was different though.

Everyone agrees that the regulator did its job by shutting down the plant for not meeting the once in a million years safety ratio that is the standard. However the plant was not a power plant, it was a research plant producing medical isotopes. So issue wasn't whether the ractor met the standards, it didn't. The issue was the probability of people getting injured or dying from a plant malfunction was significantly less than the probability of people dying from not getting those medical isotopes.

When presented with instructions to provide a temporary exception to the rule until other sources of the isotope could be brought online, the regulator said no. So things escalated until someone (parliament) had the authority to over rule the regulator.

She was fired for not granting the exception, even though she knew what the balance of probabilities were. Basically she was power tripping.

SpaceX Testing Landing Legs On Next Falcon9 Rocket

inhuman_4 Re:SpaceX (73 comments)

There isn't really anything new going on here, its just never been put togther like this before.

While NASA prefers water landings, the Soviets landed all of their equipment on the ground. So returning things to the ground isn't really that exciting. Additionally there were landing people (who are much more fragile than mechanical parts) from orbit rather than just high in the atmosphere.

And while reusable engines didn't work out that great for the Space Shuttle for various reasons. Lots of rocket engines have been used over and over on test stands on the ground. Rocket engines that can be reused isn't new tech either.

US War Machine Downsizing?

inhuman_4 Re:Time to end the military industrial complex (506 comments)

I don't know who told you the F-35 was an air superiority fighter but that is totally wrong.

The F-35 Joint *Strike* Fighter is a replacement deep strike aircraft. It will be filling the roll of the now retired F-117, and soon the F-16 and F-18.

Since the 70's air forces have followed the high-low model. An expensive air superiority fighter in small numbers, and a cheaper multi-purpose fighter in larger numbers. This is why the USAF has F-15s and F-16, and the Soviets had the SU-27 and MiG-29. The next generation is the F-22 for air superiority and F-35 for multipurpose.

Also the F-35 has nothing to do with the retirement of the A-10. The F-35 wasn't designed to replace the A-10 any more than the F-16 or the F-18 were designed to. The A-10 isn't a sexy plane in the air force's eyes, it's getting old, and no one made plans to replace it. So rather than admitting that they dropped the ball on CAS the air force is claiming that the F-35 will do the job.

Graphene towers promise 'flexi-electronics'

inhuman_4 inhuman_4 writes  |  about a year and a half ago

inhuman_4 (1294516) writes "It can support 50,000 times its own weight, springs back into shape after being compressed by up to 80% and has a density much lower than most comparable metal-based materials. A new superelastic, three-dimensional form of graphene can even conduct electricity, paving the way for flexible electronics, researchers say."

How Linus Torvalds Helped Bust a Microsoft Patent

inhuman_4 inhuman_4 writes  |  more than 2 years ago

inhuman_4 (1294516) writes "Last December, Microsoft scored a victory when the ITC Administrative Law Judge Theodore R. Essex found that Motorola had violated four Microsoft patents. But the ruling could also eliminate an important Microsoft software patent that has been invoked in lawsuits against Barnes & Noble and car navigation device-maker Tom Tom.

According to Linus Torvalds, he was deposed in the case this past fall, and apparently his testimony about a 20-year-old technical discussion — along with a discussion group posting made by an Amiga fan, known only as Natuerlich! — helped convince the Administrative Law Judge that the patent was invalid."
