Re: Yay landfill!

One of the reasons I bought it was that while not officially replaceable, battery replacement is fairly straightforward.

Which is fortunate. One day, when it was about four years old, the original battery began to fail and attempted to push the screen out the front of the thing.

Re: Green

Another thought would be this: rather than "saturation," many (video) cameras can "see" Infra Red, but report the color as green.

IR is passed by the green filters and blocked by the red ones?

Re: Patch is already out...

Was it a fix, or just an emergency kill switch while the fix is being developed?

while I'm not sure why they thought it had any chance of surviving

I'd be very surprised if they thought it would survive.

Re: Hospitality sector had it coming

I simply used an independent product comparison website, it really wasn't that onerous. You may also choose to use a trailing commission refund service to claw back the thousands of dollars the mortgage broker makes off you (or, if you don't use one, that the bank keeps for itself).

Re: Free advertising

So the "natural healthy" aspect isn't for me.

You're in luck. It's the "natural healthy" aspect that's the scam in this case.

Re: Whoops

That at least would have been cleverer

Re: You'd have to be a Dummy,....

Blue Origin's effort that was successfully landed had a velocity an order of magnitude lower than that required to reach orbit - it touched the top of the atmosphere and came back down again.

And not even that! Its lateral velocity was pretty close to zero. "All" it needed was a thrust:weight greater than 1 and enough fuel to get up and back.

Re: Business Socks

I was expecting the mission name to link to youtube. Missed opportunity Reg!

Re: SLS and Orion: not actually made by NASA...

While less powerful, the SLS's LH₂-fuelled upper stage will always be more efficient, which will likely make it measurably more effective for interplanetary missions. But yeah, the cost...

Re: Bah!

I thought stars cooked metals themselves, at least as far down Mr Medeleev's bedsheet as iron.

They do, however stellar nucleosynthesis depends very heavily on the mass of the star. This one is too light to do much more than slowly burn hydrogen to helium, so its metallicity today is probably very similar to its metallicity when it formed.

Re: Complications

Apple's "complications" even follow the tradition of borderline uselessness

Re: Perhaps - just perhaps -

The "problem" is that there is no intersection between the sets of those who understand blockchain and those who think they need a blockchain.

Re: Hybrid Rockets

A hybrid combines (some of) the complexity and cost of a liquid rocket and (some of) the inflexibility of a solid rocket. Solid rockets are very powerful, simple and cheap, while liquid rockets are very controllable and have very much higher performance.

In the most common configuration of hybrid rocket, a solid fuel is burned with a liquid oxidiser. The flow rate (and hence burn rate) of the oxidiser is controlled by the oxidiser pump/valve, but the burn rate of the fuel is affected by the exposed surface area of the fuel grain, which is in turn dependent on how much of the fuel has already been consumed. If you attempt to throttle the engine by reducing the oxidiser flow, it runs increasingly rich and performance suffers. You can certainly turn them off if you need to, but they can't throttle nearly as well as liquid rockets.
