NASA chief in Moscow: 'We will fly again on a Russian Soyuz rocket'

Re: Hyperbolae?

"something wasn't right in the lightup sequence of stage 2" - the core stage (a.k.a. stage 2) lights up on the ground, same time as the boosters. But otherwise I'm with you.

No, eight characters, some capital letters and numbers is not a good password policy

Dom 3

I had a go a few years ago. Any new password was first run through this:


which recognises that a long password of only two character types is as strong as a short password of four character types. (I didn't use the defaults, FWIW).

After that I ran it through a dictionary checker against a common password list, and a standard word list. If the last (up to) four characters were digits they were stripped before this test. And leet-speak variations were also tested, e.g p455w0rd would fail.

And people *still* managed to come up with piss-poor passwords.

I would like to have gone full john the ripper on it but I wasn't going to be able to sell that one to the customer.

Salted hashed passwords have been standard in any sane system for ages!

"he couldn't handle picking a new password every 30 days" - nor should he have to. The environment where this was a good idea has not existed for decades. Even .gov.uk have caught up:


Nor is it difficult to teach (even CEOs!) methods for creating strong but memorable passwords. No, not correcthorse(...) but using the initial letters of a phrase, or using the strong stub + domain-based suffix method.

Re: Even the greatest minds have a few failures

Channel 5's been showing a two-part documentary on Concorde recently. So if any of the following facts are wrong, blame C5. Concorde *was* a loss maker at the beginning of the 1980s. Lord King gave the whole thing over to Brian Walpole (chief Concorde pilot) and gave him two years to make it profitable. The first thing they did was a bit of market research. They discovered that the majority of passengers had no idea how much the tickets cost, and when asked to guess, significantly under-estimated. So they simply put the prices up. And from then on it *did* turn an operating profit. Not to mention the marketing benefits of making it the star of their advertising.

"we're ALL going for a Donner Kebab or a Vegan Curry". Great comment but I would take it further - the choice was between "a kebab (again)" or "something else". Having opted for "something else" the stag / hen party are then told that they have overwhelmingly rejected all animal-based foodstuffs and *must* go vegan.

"NASA also recruited 13 women who passed the necessary tests but weren't allowed to be considered because they were not test pilots" - cobblers.

Wikipedia is quite clear:

"thirteen American women who, as part of a privately funded program, underwent some of the same physiological screening tests as the astronauts selected by NASA on April 9, 1959 for Project Mercury. [... they] were not part of NASA's astronaut program, never flew in space and never met as a group"

Password1? You're so random. By which we mean not random at all - UK.gov

Stub + algorithm

It's really not hard to create easy to remember, cryptographically hard passwords that are not duplicated across sites. First, think of a phrase.

I will choose 'yet another flippin password for:'.

That makes 'yaFp4:'. Yay, six characters including upper, lower, numeric, special.

Next. What is it for? theregister.co.uk? I will choose a selection of letters in a fixed pattern; let's say, third, second, fourth, first. Makes 'ehrt'.

Now tack on a memorable number. Yer mum's birthday. You *do* remember that every year? Well, maybe if you type it in ten times a day, you will from now on. Win-win situation.

Result: yaFp4:ehrt120152

"All the kids who did great in high school writing pong games in BASIC for their Apple II would get to college, take CompSci 101, a data structures course, and when they hit the pointers business their brains would just totally explode, and the next thing you knew, they were majoring in Political Science because law school seemed like a better idea" -

I really think all space station dimensions should be translated into Standard Shed Equivalents. The Bigelow BEAM would provide the prototype: one BEAM (internal volume) = one SSE.

Because the BEAM is clearly a shed.

Re: skills shortages

What there is a shortage of is 20-somethings with enough experience to be useful but who are unencumbered by high salary expectations, children, or the realisation that masses of unpaid overtime isn't doing yourself any favours.

We're not looking for MH370 in the wrong place say investigators

Evidence for incapacitated crew?

The known flight path from 01:21 to 02:22 doesn't look like a plane on auto-pilot with an incapacitated crew. Nor does it look like someone trying to get back on the ground. It seems likely to me that it was under control. So why would it not be under control at the time of fuel exhaustion?

My favourite example. Came as example code with a microcontroller, IIRC. Needs to be viewed in a monospace font to truly appreciate it.

unsigned char i2c_rd(void) // read an 8b streaming

{ unsigned char bit_count = 0 ; // bit counter the 8b streaming

SDA=1 ; P1M2=0x05 ; // prepare SDA as input (=1)


{ eep_buf=eep_buf<<1 ; // shift left 1b eeprom data buffer

dly_usec(4) ; SCL=1 ; // rise-up SCL

shift0=SDA ; dly_usec(4) ; // read bit_n from eeprom

SCL=0 ; dly_usec(2) ; // pulse SCL

bit_count++ ; dly_usec(2) ; } // increment bit counter(repeat for 8b)

P1M2=0x0d ; return eep_buf ; // SDA open drain(return data buf)

Re: Three months....

Ummm... yes, you can read the relevant bit of Steve Squyres's book on google. And that was what they thought would kill it.

Dom 3

Three months....

It was not "expected to work for three months". It was designed and engineered such that the chances of *any* of the sub-systems failing in the first three months was fairly low.

If you take that as the base line, and do the maths, the fact that *most* of it is still working 10 years later is no longer so surprising.

As you probably can't be bothered, I will do it for you.

Let us say that the rover has 20 sub-systems, and we want to be 90% sure that none of them will fail in the first three months. To achieve that, you need to engineer each sub-system such that it has a 99.5% chance of still working after three months. Which means that after ten years, (ignoring wear and tear), it'll have an 80% chance of still working. Which means you can expect about about four out of the twenty subsystems to have stopped working. Which, amazingly enough, despite the fact that I have been using makey-uppy numbers for illustration purposes, is pretty much what we have got.

I've done this here before.
