Can anyone tell me how they might do a Moon flyby from an altitude of 26200 km?
The other worry ...
... is when it reads your mind and finds nothing there.
Years and years ago (early 1990s), I was on a project which did static analysis on a safety-critical system. By static analysis, I mean automated code verification using a tool which checked for all sorts of consistency issues (but it could not deal with anything which involved concurrency, e.g. shared memory).
It would easily have picked up both the OpenSSL bug and the recent Apple GotoFail.
The technology exists, and has existed for a while now (the tool was written in Algol and was old even when I was using it). But it is slow and expensive to use (the tool's users need to be experts).
You get what you pay for.
What's the point?
Given that Bitcoins are untraceable by design, what is the point of laundering them?

Texas Industries may be better known for chips than calculators (at least in the UK), but a quick trip over the Channel shows many TI models on sale in France.
Those were the days
I went to university in 1978, using a TI-58 and a TI-59 for everyday work (I had to have two as sometimes I would put a program on one and have it running for literally weeks). You could run either one continuously with its mains adapter (I never bought the printer). Eventually the rechargeable batteries would, die, but I suspect that if I rigged up the right power supply I could have both machines working again. I also had a TI-30 - the early version with LED display. Unfortunately the TI-30 would silently give wrong answers when the battery was low. One reason for the TI-30 was that the TI-58 / TI-59 program modules were banned in University exams.
A quick search of the usual available-to-the public sources reveals the following extra information:
Nova Centauri 2013 = V1369 Centauri, possibly identical to a 15th magnitude star seen before the nova event. There is no reliable distance estimate yet. The rise in brightness of about 12 magnitudes (from pre-event to peak) is a factor of about 10^5, and is fairly typical compared with other classical novae.
The evidence so far suggests that the star is double, with one of the components being a white dwarf accreting mass from its partner.
The primary peak brightness for classical novae is an absolute magnitude of about -8.8; the observed peak brightness of magnitude 3.3 gives a distance/extinction factor of 12.1 magnitudes. In the absence of extinction (absorption by dust clouds etc), this corresponds to a distance of about 8600 light-years.
But not too close to the South Pole
Southward of about 67 degrees south, the Sun becomes circumpolar at about this time of year, so the observer could not see the nova at all.
Your article states that "If you're at about 38° S or even closer to the South Pole, you're a chance to see it near the southern cross before dawn.". This figure is incorrect.
The nova's declination is about -59 degrees (i.e. 59 degrees south) so it will just touch the horizon for an observer at about 31 degrees north of the equator (neglecting atmospheric distortions, horizon obstructions, etc.); an observer at the Equator can easily see it. Southward of about 31 degrees south of the equator, the nova becomes circumpolar, so an observer can see it at any time of the night.
After the review, he got his peerage.

Yes, one significant figure becomes 12 significant figures after conversion...
Not just the young graduates
The over-50s aren't getting a look in either ... even with a PhD.
Given that they apparently held CVV data (a big no-no) and held all the data unencrypted (another big no-no), may I suggest that they should be held liable for any loss sustained by holders of the affected cards?
Resetting the warranty expiry timer
Drives fail shortly after the warranty expires. Vagabondo's drives still had the warranty expiry timer set to 5 years.
I scrapped a laptop last year when its HD failed after 6 years (not replaceable because the design has changed fundamentally in the interim). The spooky thing was that I had cancelled the extended warranty on 18 September, only to have the HD fail totally on 23 September, just 5 days later. How did it know?
Earth-shaking ... or just shaky?
Of course, San Francisco is just the place for an earth-shaking announcement.

And what about interviews?
As an undiagnosed-but-pretty-certain Aspie, I fully sympathise with most of the Aspie commenters above. I also have problems with sound sensitivity, to the extent that I would stay late at the office so as to get some quiet time to get all the work done.
I, too, went on a course and got some off-scale results on a Myers-Briggs assessment a few years back.
However, having been made redundant a couple of years ago, I ran into another problem. I have a difficulty with job interviews - in normal times I can cope, but in the current economic climate I have been frozen out of the job market for more than two years.
I have about the best possible presentation of Asperger's syndrome (multiple interests, which is unusual, strong mathematical and linguistic performance, and extremely strong academic performance, up to and including a PhD). My IQ is off-scale one way and my EQ off-scale the other way.
My self-assessment is that I am technically very strong but would struggle with either management or sales. Also, I am extremely non-confrontational (so I am prone to being bullied), I do not interview well, and I am prone to near-panic over the telephone.

Re: per cent
"Big Company X's share price crashed by 300 per cent. last Friday".
So their shares, previously valued at $10 each, now sell for MINUS $20.
I've known companies like that.
"Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin."

500 feet altitude
What's the reference datum here? If the navigational airspace starts at 500 feet above sea level, then that's below the local ground level.
Electrical fires and water ...
Water isn't very good for electrical fires ... and the innards of a lithium battery aren't very water-friendly either.

Not just in Britain ...
On a visit to Washington DC a few years ago, I spotted a car prominently labelled "US Secret Service - Uniformed Division". There is also a turnoff from one of the Baltimore-to-Washington freeways, labelled "National Security Agency - Employees Only".
Suggestion for the next lunar lander: install a seismometer on the Moon, with capability to beam the results back to Earth.

I went to the Los Angeles Disneyland a few years ago. At the time I had my own personal raincloud which had followed me from Los Angeles to San Francisco and back ... sure enough, it arrived in DIsneyland about half an hour after I did.
One thing about Disneyland in an extended downpour is that there weren't any queues!
Google Earth shows a blacked-out area - with obviously pixellated edges - at the position of "Sandy Island". Given that Google Earth uses satellite images, something is obviously amiss.
There is also a strange pinked-out area just NW of New Caledonia (which appears on at least one side to be bounded by barrier islands or atolls).
Icon because that's what happened to some of the atolls in this part of the world.
Many years ago I had an interview at a university spinoff, with free coffee provided. The coffee machine was the sort that started with real beans and a filter. Unfortunately they were less particular about the other ingredients ... have you ever tasted coffee with a couple of teaspoons of salt?
Re: I like the bit
... not to mention referring to coffee as a "perk".
