Another successful flight for SpaceX's Starship apart from the landing-in-one-piece thing

Re: SpaceX have turned rocket science into Spaghetti Engineering

"Look at SABRE and Skylon for the radical, new and innovative."

New as is conceived more than 40 years ago and so far only tested as discrete component stages and no integrated motor with pre-cooler has run yet? Reaction were formed in 1989. It has

Unfortunately, British R&D means British investors who are shit-scared to invest and therefore snail-pace development. The guy who came up with the idea retired 4 years ago, they've had 32 years already. There's no chance of a pre-cooled motor being in service in 8 years from now. I'll be shocked if one flies subsonic on a test airframe with three other turbofans to help it. Actually, I'll be shocked if an integrated motor runs on a test stand.

It was reported as something good when RR invested £20 million in RAL. I'm guessing one SpaceX Starship test launch costs more than that.

Unless somebody grows some balls and gives it real backing, RAL are nothing more than a long term academic study.

Sadly, the catastrophic impact with Apophis asteroid isn't going to happen in 2068

Re: Wish upon a star

A satellite orbiting a body effectively increases the mass of the body if you treat the two bodies as a single one. This will affect the heliocentric orbit of the body. If the moon vanished from earths orbit, earth's heliocentric orbit would alter.

For the small relative mass of a probe for this little asteroid, the effect is going to be 10E-alot. So it would take some distance epoch to be anything but negligible

Somebody do it in STK. Or GMAT. Or could Kerbal do it?

Re: A pound of water - in low grav

"The ISS isn't in low grav at all. It's only a few hundred miles up. Gravity up there is only about 10% lower than it is down here."

But the ISS does not meet the equal and opposite pushing back part of the equation that we have down here, so the picture is not quite complete.

Space Station has been up 22 years and a solar cycle is 11 years.

Some of it was up during the 2003 busy period.

Re: Budgets

Refurbishment of the flat is peanuts as by 1960 the buildings at 10,11,12 Downing Street were virtually condemned and had to be rebuilt behind the facia. This took almost 30 years. In about 2006 further structural problems were found and more major building took place. The place is constantly under remodelling and improvement so decorating the living quarters is really not anything to wet your bed about,

Re: "... focused primarily on Office-related skills..."

No, it was more popular when it was the 21st century equivalent of shorthand and typing.

Since it was changed to a more computing based course it has become less popular.

Maybe because some of them have trouble keeping up.

The further into maths you go, the more it depends on understanding other parts of it. It builds on itself.

Re: Shouldn't be optional

Undergrad STEM subjects such as sciences (especially physics) will require coding skills and will include coding modules.

But, of course, CompSci is far more broad a subject than coding.

Re: Have they considered paying more for IT?

My IT salary in the UK is an issue for the business.

Because they can recruit three of me in our other location in another country for the same amount.

Increasingly work is going there.

Fortunately they over there often need me over here.

Maths is something I'm not cut out for, but I have to do it.

It's practice, practice and more practice for me. I am so jealous of people with maths aptitude who do it easily. Maths is much like learning a language, or learning to play a musical instrument (minus the motor skills part). It is enormous in breadth and depth and ultimately very satisfying to get the hang of.

Comp Sci will attract a certain type of person and there are less of those than might want an IT GCSE.

werdsmith Silver badge

I'm an author and I do a bit of coding. The coding goes off into some other system and is never heard of again unless its causing some kind of trouble or is suspected of it.

But the author thing, you'll be surprised how much the success depends on promotion and getting it noticed, travelling round and appearing to do talks and signing sessions. Social media increasingly (ugh). These things are as much of the workload as the writing.

Being top quality is one saving grace for google, offering those map resources in exchange for your soul.

Raspberry Pi Foundation boss waves off listing rumours, says biz discussions may have been 'over-interpreted'

Re: Apple like :-(

Yes, but the sanctimonious zealot brigade are relatively few in number. Fortunately. And its not true that they did the repository change without telling anyone, considering they announced the Visual Studio Code addition right at the top of their blog.

Raspberry Pi also seem to have a following of people poised to jump on and magnify any perceived slip, just as Apple do.

That's the way people are and it's no big deal. Just as nobody died because you can't use a power adapter from a Macbook.

But you also see that R-Pi will accept any error without trying to worm out of it and put it right.

She pulled £37bn out of taxpayer's pockets for £20k worth of track and trace app

If pubs were open that would be another example of pub-bore bullshit. So I guess it can be Faecebook bullshit instead. The big money is for test and trace. That’s including all those millions and millions of free tests that are distributed and processed in labs and new industrial scale labs. Dunno how much the app cost to develop but I guess some was wasted on v1 which was binned and the back end stuff.

Put Sailfish on it.

My Gemini is still going strong. Had another update in February, to the Sailfish which is becoming really very nice.

Wouldn’t want any of the subsequent Planet devices, and even if I thought they were any good I wouldn’t want to be stuck with Android or a half baked Debian attempt.

I also have a ZX81 which has had an update (ZXpand) more recently than the Android Gemini.

Re: Still got one in the loft

The Stefano Merago re-writes of the ZX81 1k chess comes in multiple versions, each optimised in a different way.

I still have a working one, it has a converted to digital output in place of the tuner. I also have an excellent emulation on iPad, by a Kevin Palser..

The ZX81 was life changing for me, no exaggeration. I can still remember the feeling of seeing the thing work for the first time. It was special to be around when this movement was born and took off.

Python is in the process of supplanting MatLab for the maths stuff. Jupyter is popping up all over the place in the MatLab heartlands.

So knocking down such an established tool is going to take some doing.

Re: English is definded by it's users

And yet for all the language nazi sneering

One of the worst abominations in the English language is trying to equate people who prefer standardised grammar with a genocidal murderous fascist ideology.

English was once a set of building blocks that could be used in anyway to create communication, and any spelling that could be phonetically understood worked. Then Caxton happened. Later the Empire happened and a structure that could be more easily learned as a second language was required.

To this day, language is taught according to the rules and messing with them just make life difficult for folks who are learning the language. And teachers are exasperated by Faecebook thickos normalising “of” for “have” because GCSE examiners haven’t caught up.

And finally, “to reach out” makes me puke instantly. Someone is going to get a STFU one day for that one. Unless you are one of The Four Tops, don’t.
