It's also hard to explain how the increasing challenge of getting enough oil and gas is a result of a "false" scarcity

Here's the trick, the people who say there is plenty of stuff are throwing coal, shale, tar and anything else they can think of into the mix and pretend it's the same as easy to extract liquid oil. Another common trick is to pretend that all that unsurveyed land in Iran, the arctic, wherever has huge oil basins when we do not know one way or another. There's plenty of fossil fuels. Oil we can get out of the ground - not so much. The only reason I have the job I have is that the more computing power you have the easier it is to find the stuff from survey data.

Jetpacks are possible, but probably will never be practical.
The issue is the energy density of the fuel. If the energy density is low it takes a lot of fuel, which reduces flight time. If the energy density is high, it's a bomb strapped to someone's back, which means adding safety features, which add weight, which reduces flight time.
Jetpacks have been made, and they do work, but only for short times. You'll never fly around in one like a helicopter, the chemistry simply doesn't support it.

Unfortunately much of that is outright lie. Lockheed Martin specifically sold F-35 to other countries under the umbrella of "you can replace all your fighter, attack and close combat support aircraft with this one machine". This is why they got so many countries on board with financing in spite of having no aircraft to show for it.

This has since been proven to be false, to the point where several countries like Australia have opted to buy other aircraft like F/A-18E/F models to replacing their aging fleets instead of F-35 after failures of F-35 became evident.

As for "design goals" as it comes to F-35, is there really anyone still having that discussion, other than Lockheed Martin shills? We already know they failed at meeting essentially all of them, and design requirements had to be continuously reduced so that aircraft would have at least some chance of meeting them. Knowledge of this is widely available in mass media.

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

That's about when PR companies decided to put money into "social media" and this place started to get astroturfed, but it does appear that your comment was wrongly labelled by Exitar.
Let's consider what is now a very old example of this sort of contraversy. The F111 also had a variety of early problems, as mentioned by others here, yet despite all those problems decades ago they were useful enough in some roles that there were retained in service long enough that I saw one flying the year before last. There are none flying now but nearly 40 years of service is enough for a jet fighter isn't it?

Point one: I'm looking at it from the point of view of other countries. I readily concede the fact that US will never buy a French jet, even if it's far better suited for the role. It took immense amount of wrangling just to get Harrier in, even though it literally had no alternatives.

Your second point is moot. F-35's commonality is reported at around thirty percent today, and it's likely to go down rather than up as development continues. This is actually one of the biggest failures in the program, and was widely reported.

Your third point is extremely debatable. F-35's stealth is already been reported to be exceptionally lacking in all but frontal hemispheres, and in addition to that it has very little in terms of payload when it's stealthy. It needs to have external hardpoints (read: no stealth from any direction) for any meaningful strike package for example, or to have a meaningful range which it woefully lacks.

So we go back to point one, which as I admitted, I readily concede. But in that regard, there is one point that is being argued in US today: that F-35 program should be scrapped and in its place US should develop three separate fighters (because of point #2 being proven largely failed today). This would get all users an aircraft that is actually at least decent for the designed purpose, instead of an abortion of an aircraft in all usage scenarios that F-35 is increasingly proven to be.

Precisely! The cow fart thing has been deliberately overblown by vested interests (ie: evil environmentalists want to take away your hamburger!!!!). The fact of the matter is that today's cow fart is tomorrow's cow food. Of course if we could stop cows farting and burping we could reduce our overall impact on climate but the real climate related problem not just with with cows but with agriculture in general is land use, ie: flattening forests and scrub land, draining wetlands, etc, to make way for pasture, shrimp farms, etc.

At the end of the day there aren't too many cows or pigs on the planet, there are too many people. However according to said vested interests uttering the simple fact that overpopulation is the root cause of the current environmental collapse somehow means that I want to start exterminating humans en-mass? - Not at all, I just happen to be concerned that collectively we appear to be behaving with all the forethought of a jar of fermenting yeast and as a consequence my three grand kids may suffer the same fate if we fail to reverse that trend.

You forget that capabilities of S-300 are well known, because several of the newer NATO countries have the system's naval version on their ships.

S-400 is arguable, and S-300 would definitely pose a significant threat to older planes like F-16 and F-18 without electronic warfare support.

However the rocket at the edge of its operational range is at a massive disadvantage in terms of power of its guidance system vs power of nearby powerful jammer.

You are grossly misinformed. "Wild weasel" is a US program to attack SAM targets with HARM missiles. It was just that, nothing less, nothing more.

Modern NATO aviation, when striking sites defended by SAM installments use dedicated electronic warfare aircraft. These aircraft are designed for extremely specialized role that has nothing to do with destroying SAM targets. Their goal is to track, locate and jam incoming radar-guided missiles. They render stealth moot because they go for exact opposite approach (overloading tracking system with false information instead of depriving it of information) that gets you the exact same end goal as stealth - near immunity to radar guided missiles.

Jaws was a great movie, however it was just a fucking movie.

Mosquitoes kill around one million people a year worldwide.
Domestic dogs kill over 3000 people a year worldwide (over 50,000 if you count rabies).
A kick to the head by a cow or horse kills about 40 people a year in the US alone.
ALL species of sharks combined have killed an average of 4.2 people a year worldwide over the last decade.

Too bad they didn't feed the sharks consservtionist[sic] brains.

Sure, Eisenhower warned of the problems but lets try something radical like reading the entire speech. Here's some context to whet your appetite...

A vital element in keeping the peace is our military establishment. Our arms must be mighty, ready for instant action, so that no potential aggressor may be tempted to risk his own destruction....[snip]...But now we can no longer risk emergency improvisation of national defense; we have been compelled to create a permanent armaments industry of vast proportions....[snip]....In the councils of government, we must guard against the acquisition of unwarranted influence, whether sought or unsought, by the military industrial complex. The potential for the disastrous rise of misplaced power exists and will persist.

In other words, Eisenhower saw the overwhelming power of the MIC as essential for peace and at the same time was warning the nation about the potential of a home grown Hitler.

I'm sorry, I just read through that paper, and nowhere in it does it say that a decline in Antarctic ice is a forecast of AGW. That's one of the worst examples of "proof by ghost reference" I've ever seen. Not to mention that the paper is mainly focused on the Antarctic Peninsula, the one place that actually gets melt on more than super-rare occasions and juts into a different climate zone.

Submission + - IBM to invest $3 Billion for Semiconductor Research (wired.com)

Taco Cowboy writes: A few decades ago the news of IBM investing billions in research did not even raise an eyelid, because that was what IBM did, and what IBM was good at

However, IBM has changed so much that nowadays when IBM wanting to invest $ 3 Billion in semiconductor research it hits the news headlines everywhere, from Bloomberg ( http://www.bloomberg.com/news/... ) to WSJ ( http://online.wsj.com/articles... ) to CNET ( http://www.cnet.com/news/ibm-s... )

Is what happening to IBM a reflection of what is happening to the American technological front ?
