Comment Re:"Clock parts" wired together in an adhoc fashio (Score 1) 802

Is the Moon a hoax bomb? If I claim it is a bomb, about to go off, is that now a suspected hoax bomb? Give me a break.

Anyone can suspect anything or anyone of anything. That doesn't make it a justified belief.

In real life we want justified beliefs.

The complete lack of anything resembling an explosive or detonator makes anyone suspecting it to be a bomb very stupid.

Yes, but to be a hoax *bomb* there would have to be a hoax *explosive*.

Where's the fake explosive in any picture of this device???

There isn't one.

Did he even claim it was a fake bomb at any time??? The answer seems to be: no.

It's all a load of rubbish, and the police knew that, which is why they let him go.


Microsoft Blames Layoffs For Drop In Female Employees ( 179

itwbennett writes: This year, women made up 26.8 percent of Microsoft's total workforce, down from 29 percent in 2014, the company reported Monday. In a blog post discussing the numbers, Gwen Houston, Microsoft's general manager of diversity and inclusion, pointed the finger at the thousands of layoffs the company made to restructure its phone hardware business: 'The workforce reductions resulting from the restructure of our phone hardware business ... impacted factory and production facilities outside the U.S. that produce handsets and hardware, and a higher percentage of those jobs were held by women,' she said.

Submission + - Bring back MST3K Kickstarter Hits $2 Million Goal (

Nova Express writes: In a follow-up to the previous Slashdot story about the Bring Back Mystery Science Theater 3000 kickstarter, they have already hit their $2 million goal with 25 days left, which means they'll produce at least three new episodes. Now we'll see if they can make their $5.5 million stretch goal and produce a full 12 episodes.

Explosions and Multiple Shootings In Paris, Possible Hostages ( 965

An anonymous reader writes: Multiple sources are reporting that at least 18 people are dead across three shootings in central Paris. The Associated Press reports as many as 26, as of this writing. Some victims were at a restaurant, while others were at a nearby theater. Early reports indicate there may be a hostage situation with more people at that theater. Police have also confirmed an explosion at a bar near Stade de France stadium, where a football match was underway between France and Germany. There are reports of other explosions heard at the stadium as well, but no details yet. "The attack comes as France has heightened security measures ahead of a major global climate conference that starts in two weeks, out of fear of violent protests and potential terrorist attacks." The attacks occurred not far from where the Charlie Hebdo shooting happened in January. "French news media reported that Kalashnikov rifles had been involved in the shootings — a favored weapon of militants who have attacked targets in France — and that many rounds had been fired."

> Their tech works and they built it.

LOL, I don't think so.

This is the tech that keeps lithobraking and exploding when it's supposed to be landing on a barge. They've been trying to pin a landing since the first flight of Falcon 1. They're currently on Falcon 9.

Maybe they'll succeed one day, but the very high performance rockets they build are obviously *very* fragile.

And that's the problem with their approach, pure rocket reusables have to be super lightly built, and then it's very difficult to make it back down to the ground.

People do this kind of stuff all the time.

Many people wager their lives on their belief in a God, and... usually die.

Actually, I once did a computer model of SpaceX-style reusability, and that's actually what my model showed me, that it would be extremely hard for SpaceX to get it to work.

But my modelling shows that Skylon ought to make orbit, and return and land safety with comparative ease, Their design is very insensitive to weight growth; and they actually have spare mass built into their design in case things are harder than they look.

But yeah, I do agree with you pretty much on the economics, that's the worst part of their design. But compared to the economics of the Space Shuttle... ;)

> Sure, at this stage of any project it's easy to be "looking at" very low costs. They haven't done anything yet. The nature of these kinds of projects is there are a whole bunch of costs, technical an regulatory, that aren't apparent until you actually start building something.

I don't agree. For example, the Space Shuttle estimates were about on the money. As in they said, the cost estimate is $X, but we'll need $1.2 X, to allow for obvious contingencies. President Nixon went: we don't budget contingencies, we'll give you X and then fund the overrun later. NASA: OK boss.

So actually, it cost what they said, but it looked to the rest of the world like an overrun.

And the Space Shuttle main engine was about as complicated as SABRE looks like it will be, maybe more so, it was an unreasonably complicated design.

And Reaction Engines actually have a careful design, with computer modelling of everything. That bodes well for a relatively straightforward detailed design and build. The X-33 had none of that, and when they got around to it, they found the horizontal stabilisation was total shit.

And the engine is particularly clever in that it works almost the same at all speeds; the precooler means that it doesn't care whether it's at ground level or Mach 5, the air behind the cooler is at the same temperature. That means, like a rocket engine, they can do almost complete testing when stationary. And the precooler also, they've already tested the precooler; it works fine. And the precooler was the most challenging bit of the whole system; it's something like half a gigawatt per tonne of cooling.

The take-home message is not that it's not a clever design, it's that most of the clever bits are easy to ground test. About the only bit they can't totally test on the ground is the aerodynamics of the aeroshell- but that was basically the same problem that the Space Shuttle faced and dealt with.

Actually, the Skylon group predicted that the X--33 wouldn't work. They said that the X-33 was too tail heavy. And fixing it would mess up the payload fraction. And they were right.

It's difficult to get your head around just how far ahead these guys have been for about 20 years.

The ultimate reason is that they built a computer model of launch vehicles, which they fiddled with until they got a plausible vehicle. Then they did a back-back comparison with a pure-rocket vehicle, and found that there was no big advantage. Then they fiddled around more, and out popped Skylon, and then they found it *seriously* beats pure-rocket vehicles; it's not even close.

Skylon is looking at costs starting around $500/kg and then going lower. SpaceX won't be able to get down to that.
