Just go for it.

It's not rocket scien... oh wait.

Go for it anyway.

Re: Weight Savings

As far as I know, the only design decision made for cost reasons was to make all of the engines and fuel tank segments the same. Which is why these rockets are the same thickness all the way up, rather than the saturn 5 with each stage a bit thinner. But I doubt you'd save much weight by changing that, you still need the same size, only the shape changes.

The plans are going to sound crazy

As if bringing something the size of a 20 storey building travelling at over 7000kph over 100km high down onto a boat named "Of course I still love you" doesn't sound crazy.

Qualcomm drops antenna, amplifier silicon on OEMs

Geoff Johnson

Not such a bad read.

I can see a lot of people didn't get all the way down to the comments button at the bottom, but I found some nice nuggets of interesting information between the chip numbers. Please don't let the lack of comments put you off this more technical side of the news.

Sounds to me like someone has a patent on phase change memory, so they want to pretend they're not infringing.

UK Home Sec's defence of bulk spying: We 'found' a paedo (we already knew about)

What happens WHEN (not if) some of this slurped data falls into the wrong hands. Though to be honest, I think anyone who wants it is "the wrong hands."

You can hack a PC just by looking at it, say 3M and HP

Geoff Johnson

Re: This is far cheaper...

That would look better if the screen was black without the goggles. Working at a monitor that looks off would really confuse people.

EDIT: before anyone mentions it, I know it wouldn't work that way, but it would look cool if it did.

NEW ERA for HUMANITY? NASA says something 'major' FOUND ON MARS

Geoff Johnson

Re: It'll be a rock

Reminds me of this...

LISTER: OK, OK. What's Holly spotted?

RIMMER: An unidentified object.

LISTER: You mean a rock.

RIMMER: It might not be.

LISTER: They're always rocks.

RIMMER: Mostly they're rocks, I agree, but maybe this one's different.

LISTER: Rimmer, there's nothing out there, you know. There's nobody out

there. No alien monsters, no Zargon warships, no beautiful blondes

with beehive hairdos who say, "Show me some more of this Earth thing

called kissing." There's just you, me, the Cat, and a lot of floating

smegging rocks. That's it. Finito.

Sorry, can't get the formatting right.

Volkswagen used software to CHEAT on AIR POLLUTION tests, alleges US gov

Geoff Johnson

It passes the test as written then.

So it detects when it's stood still idling and runs in low performance low emission mode. When under normal use you get decent performance but a bit more emission. Surely it's a pass. Unless you ban them from varying the engine map for different situations. In which case we're back to carburetors and even then only if they have a manual choke.

I know this is diesel so the carb bit doesn't really apply.

RFID wants to TRACK my TODGER, so I am going to CUT it OFF

Geoff Johnson

RFID reading washing machine.

I guess its possible to have an RFID reading washing machine that reads the washing instructions and runs the appropriate program. However I can see it going wrong in so many ways. Like complete refusal to wash any of your clothes together because the instructions vary in some negligible way. Washing machine noticing a neerby dishcloth and putting your best shirt through the ulta-violent don't give a toss cycle. Levi recommend aerial, you can't use persil for this garment. Can't contact the server at Levi.com, please try again later. Etc. Etc. Etc.

Google's new scribble-tab-ulous handwriting interface for Android

Geoff Johnson

Local Processing

though Imon-line now, I tried off- line. It seems exactly the same.

Using it to write this is taking ages though.

I think it needs more language Knowledge. It could also used better word suggestion system that knows what letters can get missunderstood.

overall not as bad as I expected, but very slow compared to typing.

HOT YOUNG STAR about to GIVE BIRTH, long range images show

Geoff Johnson

Looks to me like at least one big planet near the star, then some small ones before several more big ones. I suppose this kind of fits with the high number of very large known exoplanets that have close in orbits. Though that could also just be down to big close planets being much easier to detect. Apart from the big close one, its a bit like our solar system too.

My biggest conclusion is that I want to see more images like this.

POND SCUM shine a path to more efficient solar cells

Geoff Johnson

Re: Evolution works

I'd bet a lot of solar cell research is very similar to evolution anyway. If a formula works, try tweaking it a bit for the next batch of cells. If a formula doesn't, work very well, drop that line of research. Give it a few billion years and they'll have it cracked.

S is for SMACKDOWN: Samsung takes Galaxy Tab slab war fruit-side

Geoff Johnson

Re: 2560 x 1600 resolution

I guess size makes a difference. TV size displays need big machinery to make them. I also suspect that there'll be X defects per square yard of screen produced, so the bigger the screen, the lower the yield.

China 'in discussions' about high-speed rail lines to London, Germany – and the US

Geoff Johnson

Re: Ring of Fire?

Google for tectonic plates and you'll find lots of maps showing where the boundaries are. It looks like the long line to the USA would cross one boundary, and that will be well inland. It's also no a particularly active boundary from what I can see on some of the pictures.

BuzzGasm: 9 Incredible Things You Never Knew About PLIERS!

Geoff Johnson

Re: Pliers cause pain

That reminds me of the EHT dance. Everyone knows the moves and the words but doesn't realize it. Then one day tinkering with a car, you get a shock from an EHT lead and the information comes magically to hand.

The dance involves jumping up and down while slowly spinning around and violently shaking the shocked hand while trying to put it under the opposite armpit without stopping shaking it.

The words (shouted in time with the jumps) are Bastard, Bastard, Bastard.

Everyone I've ever seen shocked by an EHT lead has reacted exactly the same way.

Virgin Galactic's supersonic space ship in 71,000-ft record smash

Research

There must be some research that can be done in 5 minutes of zero g. The alternatives I can think of are 30 second bursts on the vomit comet, or full blown orbital flight. One may be too short, while the other may be too expensive. I expect this would hit the sweet spot for something, I just can't think what.

Just remembered drop towers, but they give really short times at zero g, comparatively cheap though.

NASA and Google team up to buy into quantumish computing

Geoff Johnson

Must be more to this than sharing the hardware.

Google or NASA could afford a 15 million computer n their own. Presumably this is a joint research project and the new toy is just a tool that they'll be using.

Re: So what's the airspeed of an unladen Instagram?

It's a montage of shots from the arm. Kind of myspace style. Careful stitching of shots with the arm in different positions to remove the majority of the arm its self.

Voyager's 35th birthday gift: One-way INTERSTELLAR ticket

Geoff Johnson

Re: Isn't about time we built another Voyager?

We are / do / have.

New Horizons is heading for Pluto.

Dawn is off to Ceres having already surveyed Vesta.

Cassini is orbiting Saturn.

Curiosity is trundling around Mars.

And that's just the few that spring to mind.

There is a tendency to go to other planets and stay there rather than doing a tour of the solar system, but you can get a lot more science done it you have a few years in orbit, rather than an hour flying past. New Horizons is the exception to the rule but the physics of getting there make an orbiting probe a bit too tricky.

GAGA: Spinning blades, welding, wi-fi, what could possibly go wrong?

Geoff Johnson

Thinking out of the box.

So, navigating by on-board sensors is proving tricky, but remote control is going ok.

Why not have the brains of the beast in a stationary location controlling the mower remotely using a stationary camera that can see the whole lawn. If you mod the camera for IR ( See http://www.hoagieshouse.com/IR/ ) and paint the mower black there'll be a really good contrast between the mower and the grass. Of course, the higher the camera the better, as you'll get a more plan view, do you have a roof overlooking the grass?

If you still want the whole thing in one unit, maybe you could use a downward looking wide angle IR camera mounted well above the mower body grass will be bright white to an IR camera so it should see the lawn edges. You'll still need a coarse position from a GPS or something similar though.

Re: Yes, this is a serious question.

Thanks, I may have a try myself then.

Over here in England we have more problems with floods than fires, and the extra moisture should protect the roots from excess heat.

By the way, I found a patent for this has been filed.

Air admittance valve

Stick in a T piece with a valve to let air back in if the engine fails to fire. As mentioned before, you'll have to let the vacuum out before you can open the chamber.

Pay-by-wave: At least it's better than being mugged

Geoff Johnson

Maybe there's another way...

Have two people carrying a box each linked by some wireless data transport mechanism. One person holds their box next to the victims pocket. The other person buys something at he supermarket and waves their box at the payment terminal. The two boxes relay signals from the card to the terminal and back. The terminal and card think they're in proximity and talk quite happily via the wireless link. Money goes from victim to legitimate retailer. Goods go anonymously to the bad guys to be sold on e-bay.

So, buy your RF screened wallet from Geoff's shielded wallet store now.

But the Peltier effect can be useful the other way around.

LOHAN to suck mighty thruster as it goes off, in a shed

Geoff Johnson
Mushroom

You've probably already considered this, but...

Put the vacuum pump tube near the top, then you don't need to go through the outer tube.

Get the temperature low before pumping out the air - the thermal conductivity of a vacuum is pretty low.

And as mentioned above, make sure your lid doesn't get frozen on. I've seen rigs like this blow their top due to frozen relief valves and it gets pretty violent.
