That is correct. The heat generated from traveling at > Mach 3 caused significant expansion of the (mostly titanium) body, so there were gaps between body panels. This wasn't an issue, because the SR-71 would refuel just after takeoff before proceeding on its mission.

Comment Re:1% is probably true for all opiates (Score 1) 499

No, physical dependence is most definitely not addiction. This is a very common misconception, one that even many doctors believe.

Take for example a chronic pain patient who has been taking opioids for an extended period of time to manage their pain. They take it exactly as prescribed, do not get high, never run out of medication early, and do not constantly ask for a higher dose (unless their condition worsens or because of tolerance). They take opioids because it treats their severe pain well enough for them to lead a normal life and to be able to work full-time.

These patients of course have developed a physical dependence on the opioids, and if the underlying cause of their pain is cured, they will need to taper down their dosage to avoid physical withdrawal symptoms.

But they are certainly not all addicted to opioids.

Submission Apple co-founder Steve Wozniak on Samsung patent verdict->

dgharmon writes: “I hate it,” Wozniak told Bloomberg in Shanghai today, referring to the patent battle. “I don’t think the decision of California will hold. And I don’t agree with it — very small things I don’t really call that innovative. I wish everybody would just agree to exchange all the patents and everybody can build the best forms they want to use everybody’s technologies.”

Submission What Are the Odds of Another 9/11 Event?

Hugh Pickens writes writes: "Statisticians make predictions about all kinds of phenomena governed by power laws, everything from earthquakes, forest fires and avalanches to epidemics, the volume of email and even the spread of rumors. Now "This Week" reports that two statisticians — Aaron Clauset at the Santa Fe Institute in New Mexico and Ryan Woodward at the Swiss Federal Institute of Technology — have put together a comprehensive global database including 13,274 terrorist events from 1968 to 2007 and created an algorithm to predict the odds of a large-scale terrorist attack with similar or greater consequences happening again. They estimated that the historical probability of an attack on 9/11's scale happening at anytime in the last 40 years was somewhere between 11 and 35 percent. "That's important," says Technology Review. "It means that 9/11 itself was not at all unlikely given the pattern of terrorist activity leading up to it." Assuming that the number of terrorists events per year remains roughly what it is now (2000 per year), the likelihood of another large-scale terrorist attack anywhere in the world (with a death toll greater than or equivalent to 9/11) is between 20 and 50 percent over the next decade (PDF). A 50-50 chance, the top of that range, means "a catastrophic attack is as likely as not.""

Submission Ask Slashdot: Best storage solution for a modern media server? 2

An anonymous reader writes: I'm building a media server for ripping my excessive collection of audio CDs, but I'm having trouble deciding how I should set up my storage. I want some kind of nominal protection against a drive death to save me the hassle of re-ripping in the event of a failure, but I feel like all the usual suspects (raid 5, unraid, flexraid, etc) take almost as long to rebuild as it would take me to just re-rip. Are there better solutions these days, or should I just say screw it and go JBOD?

It's not just rifle rounds. Even a .22 LR pistol has no problem breaking the sound barrier.

You are correct with suppressors though. The supersonic "crack" of a projectile is quite loud, and suppressors do nothing to reduce this, except for a small decrease in muzzle velocity. Still, a suppressed rifle is much quieter than an unsuppressed rifle.

"Manual transmissions do, however even modern under power you're going to have a very difficult time shifting to neutral w/o the clutch... "

No you won't have a difficult time at all shifting into neutral without the clutch. Even under power it should pop out of gear with relatively little force.
