All 3 V-bombers

Can be seen at Duxford as static displays. Saw a Vulcan do a show there in the late 70's. Turned away from crowd and let the engines rip. Quite impressive.

Why SpaceX will sort out Sunday's snafu faster than NASA ever could

Re: No wonder

FFS. All covered extremely well in Vance's book about Musk. Read it before commenting.

But in short - he nearly blew his entire fortune (within a couple of day of going broke) on SpaceX and Tesla.

You last line is rather disingenuous. MS said no significant KNOWN issues, whilst you wrote no significant issues.

Re: Physics Says...

AFAICR, the LOX tanks also have the helium pressurant bottles in them, so if one of those ruptured, there could be overpressure. BUT, that would be the first thought, and not counter-intuitive as tweeted by EM.

Re: Annoying fan boys...

@Jeffy.

So...people are not allowed to extoll the virtues of something they cannot afford, even the financials? I could extol the virtue of a decent modern good MPG car, diesal or petrol. But I haven't got one - I've got a 10 year old petrol Civic (230k miles and counting!). The reasons I cannot afford a Tesla S, even though it might pay for itself, is the initial upfront cost. Not the cost of ownership post initial purchase.

Your point makes no sense.

Majority of driving is a 70mile round trip to work. I think a Tesla S or Model 3 would be ideal for me.

SpaceX gets ready to crash barge-land ANOTHER rocket

James Hughes 1

Re: fuel?

I believe the consensus is that it's a lossy system, not using RP-1, but it is not yet known whether it vents overboard, or to a low pressure catch tank.

It's not transferred back to the fuel tank as that is on the other side of the LOX tank and the pipework would be too heavy and awkward.

Re: fuel?

No he doesn't. The grid fins as I understand it use separate hydraulic fluid tanks and are a total loss system, in that the fluid is not recycled back in to the tank. Hence it could and did run out. They don't use fuel (aviation kerosene) as far as I know.

EDIT: I take that back. There is some evidence that it does use RP1 that drains back in to the tank. Apologies. http://space.stackexchange.com/questions/7771/why-does-the-falcon-9-consume-hydraulic-fluid

At last, switching between rubbish broadband providers now easier

James Hughes 1
Silver badge

Just switched from EE to BT

Simply for cost reasons.

Went through very easily, EE supplied MAC code with little effort, BT took MAC code and provided new router which works better than the old one (must be 6-7 years old). BT switched over seamlessly, didn't even notice when it happened.

We have yet to see if service is better or worse. So far seems pretty much the same.

Already happens.

On exercise some years ago, the British army chaps were about to attach the American base, when the food trucks turned up. Set out tables, got food ready. All the American soldiers decamped from position and went to eat. Note, ALL the American soldiers.

Nothing like a paltry exercise was going to get in the way of their grub time.

I absolutely disagree that Scratch is a waste of time. It's a fantastic introduction to almost all the basic concepts used in computing. And as an added bonus there is the instant gratification of seeing stuff working, which you don't generally get with textual languages, even python.

Re: Now that ElReg is...

Takes about two weeks to make one from kit. Friend did exactly that. Others can take much longer. Took me some months to make a Westfield 25 years ago, but that included sourcing a lot of parts myself. Caterham kits have most of the bits you need already.

My Locost still isn't finished and I started it over ten years ago. But then I did make the chassis and build the engine from bits. (ex. FFord engine, +60 overbore, twin dellorto 40's, stage 3 head, high lift cam etc).

Building these things is fun, unless you have children. When you never have time.

Fire stick

Accidentally got Amazon Prime the other day by pressing the wrong button when buying something. But tried it out on the PS3, and really quite like it. So bought a Fire Stick as Ps3 needs to be repaired (coincidence?), and, also, really like that too (but did work on the chip in it so biased). Been struggling getting the other half to stop watching stuff. Not tried other media streaming services though, so comparison not available!

SpaceX asks to test broadband in SPAAACE

Re: Testing antenna configurations?

Hmm, let me think.

Do I believe SpaceX, the rather clever people behind the satellites and the ones coughing up the rather considerable costs to launch them, or some Register commentators.

Touch choice.

On the other hand, perhaps it's just a little bit more than 'testing the antennas'?

I eventually got some money out of the surveyor who did my house, and failed to notice that the oil storage tank leaked like a sieve - i.e. you could actually see the drops coming out. How the previous owners hadn't noticed it is weird. Well, not really.

I did threaten them with all sorts though as they kept denying any responsibility.

NASA hands Boeing first commercial crew contract for SPAAAACE

Re: There is a way to meet the deadlines

All rocket stuff is designed to work right first time, and it's generally successful. For example the Delta4 rocket has had only one partial failure ever.

Of course SpaceX do a lot of up front stuff, just not as much as ULA or Boeing. They are faster and more agile. Which I believe is a faster way to get stuff working than huge amounts of paperwork and simulations.

Re: There is a way to meet the deadlines

Boeing do a LOT of paper work/design analysis up front, SpaceX do a lot of iterative development. Different processes, so different schedules.

Of course SpaceX will still be first by miles and much cheaper because they are not Boeing.

Re: Less diversity

Chip cost is a big reason, I think, why these companies get together. The cost of making a modern SoC from scratch is MASSIVE. Many $10 of Millions if you want anything other than ARM standard designs (and they are not cheap)

And more to the point, I sold all my Brcm shares last week, just before they went up 20%, so a bit pissed. off.

Maserati Ghibli S: Who cares what Joe Walsh thinks?

James Hughes 1
Silver badge

When I was racing you often had to change gear in long corners to keep in the best power band (Corum at Snet rings a bell, as does the corner at the end of the start straight at Lydden Hill). Usually changing up of course. Changing down you need to heel and toe and know what you are doing, can result in spins otherwise.

Look up trail braking for braking in to corners.

Very few examples of bad driving end in accidents. I see bad driving every day, I sure I've been responsible for some of it. Almost everyone has driven badly at some point. You don't have to drive badly all the time. Whereas a automomous car? When will that drive 'badly'?

Re: Honestly? Really?

Glad you used the troll icon.

Planes are incredible safe, even when entirely controlled by computers. Not a valid argument.

Google beta point. WTF? You really really think that legislation will let 'bad/untested/beta' driverless cars on the road? These things are going to be tested to the nth.

Humans are terrible drivers on the whole. Driving when tired, when distracted by children, when really bad drivers who should never even be allowed in a car. May not be there yet, but computers are guaranteed to eventually be better than human drivers. And I suspect that time is not that far off.

Privacy and data storage

These cars have a lot of high resolution camera. The data storage for just single 1hr trip will be really quite large (let's say 4x1080p30 cameras, that's multiple GB per hour). Now multiply that by every car, and the numbers of hours driven.

Not enough storage in the world for that lot.

Samsung S6: You might get a Sony camera in it - or you might not

James Hughes 1
Silver badge

Samsung do actually have very very strict quality control and testing for their cameras (I know, I've been on the receiving end of it), down to nitpicking about individual pixel differences between two cameras or ISP's

So its surprising that there is any real noticeable different between these sensors. I wonder if they are relaxing the rules a bit.

They also dual or more source components, and are on a constant search for cost reduction.

Which all in all makes them a PITA to work for.

People like that do exist, I'm one, but we are all getting on a bit now. But I do occasionally come across someone younger who really knows their stuff. But they tend to gravitate to the high paying, interesting jobs, and although software for deep drilling sounds quite interesting to me, does it compare with high frequency trading, advanced camera work and image analysis, video processing etc?

Did I say it was impossible? No, didn't, I said it was difficult. Not perhaps technically difficult, but overall, difficult.

Now go and install everything required for a HD capable satellite link on an unmanned barge. For the cost of simply bringing the SD cards back as the barge is towed in. Also, make the system literally bomb proof, because there is a big flamy thing going to be landing on or near it.

Re: Video

Even at lowest thrust the single running Merlin engine has a T/W ratio > 1 over the empty stage, so it needs to 'hoverslam', i.e. high G deceleration at last second reaching 0m/s at deck height.

Ther ewas a sticky valve somewhere that cause delays in the control system, which they think causes the wiggling.
