WileyFox Swift 2: A new champ of the 'for around £150' market

David Harper 1

Has proper dual-SIM functionality been restored?

Is it possible to disable one of the SIM cards in a dual-SIM Swift 2 via the Settings app? This capability disappeared when my first-generation Swift was "upgraded" to Cyanogen 13, which made it all but useless as a dual-SIM phone, particularly when one SIM is for UK use and the other is for the US.

'Extra-supermoon' to appear next week

Re: Its just a big moon.

Several billion years ago, the Moon was actually much closer to the Earth, although not quite *that* close. Our earliest distant ancestors would have seen spectacular moonrises, except that, being bacteria, they didn't have eyes.

Re: Its just a big moon.

"It was near a half moon last night and the dark/light edge looked spectacular when the clouds weren't hiding it."

The technical name for the dark/light edge is "terminator", and it's even more spectacular when viewed through a telescope or binoculars because that's where the Sun is just rising, so the shadows are very long, which highlights the lunar relief. If you know when and where to look, you can see the eastern edges of craters in brilliant sunlight whilst the interior of the crater is still in darkness.

Re: Ok, so...

Every line of source code should begin with six spaces, as the venerable and wise John Backus taught us almost sixty years ago. Except for comments, which start with a 'C' in column 1, or continuation lines, which have five spaces, an arbitrary character in column 6, then the rest of your statement from column 7 on.

A British phone you're not embarrassed to carry? You heard that right

David Harper 1

Have they fixed the "no way to disable a SIM" problem in Cyanogen 13?

I've had a Swift for several months. It's a nice little phone, but after the Cyanogen 13 "upgrade", I'm no longer able to disable a SIM through Settings. This is a serious flaw in a phone that's advertised for its dual-SIM capability, especially as I planned to use it with a UK SIM and a US SIM installed. Now, when I'm in the US, I have no way to disable the UK SIM. Recent developments at the organisation behind Cyanogen make me pessimistic that this will be fixed. Fortunately, I only spent £100 on the phone, but I'm still annoyed.

Cyanogen mods self away from full Android alternative

David Harper 1

Re: My other half hated it...

Worse still, the most recent Cyanogen update removed the ability to disable a specific SIM card in dual-SIM phones like the WileyFox Storm and Swift. The option simply vanished from Settings. This makes WileyFox phones much less attractive to anyone who plans to use the dual-SIM capability whilst travelling abroad.

Adventures in (re) naming your business: Fire up the 4-syllable random name generator

David Harper 1

Choose your company name carefully

I'm reminded of a story that I heard thirty years ago about the Italian government's plan to set up a genetics research centre. They were going to name it by prefixing 'gen' (to signify genetics) to the name that Italians give to their own country. I'll let you figure it out. Suffice to say, they went with a different name.

Power cut crashes Delta's worldwide flight update systems

David Harper 1

Re: @choleric

The length of the mean solar day *was* 86400 SI seconds around the middle of the 19th century. That rotation rate was embodied in the astronomical observations that were used to define Universal Time in the late 19th century. When UT was replaced as the best measure of time by Ephemeris Time and then by International Atomic Time in the 20th century, both ET and TAI were defined to have the same length of second as UT. And that's why we have a problem with leap seconds: the SI second reflects the rotation speed of the Earth almost 200 years ago, not today.

Brexit threatens Cornish pasty's racial purity

Re: Sarcasm

"the thought that somebody in Romania could start churning out Cornish Pasties isn't one of the overriding arguments I'm struggling with"

I seem to recall that Romania was one of the countries implicated in the horse-meat scandal back in 2013. I can see the marketing slogan already: "Fred Ceaucescu's Genuine Cornish Pasties -- First Past The Post!"

Neo4j CEO: We're at 'a huge inflection point for graph databases'

David Harper 1
FAIL

One major flaw with the free version of Neo4j

>> “Our summary is, whenever you can use MySQL free, you can use Neo4j community for free,” said Eifrem.

Err, no.

You cannot perform hot backups on a running instance of Neo4j community edition. You must stop the instance, then backup the files, then re-start the instance. For hot backups, you must buy the enterprise edition.

You CAN perform a hot backup on a running instance of the MySQL community edition, using a free, open source tool such as Percona XtraBackup. Free database server, free hot backup tool.

You do backup your databases regularly, right?

From the Ordnance Survey blog post: "What is amazing is how close the surveyors in 1949 were. The measured height has changed by centimetres, but those centimetres mean we now need to round up rather than down."

And they did it using only theodolites and chains, the old-fashioned way. Well done, 1949 OS chaps!

If the perpetrators are planning to demand money to call off this DDOS attack, then they can't be very bright. UK universities are not exactly awash with spare cash, except perhaps for the salaries that some Russell Group institutions pay to their chief executives.

This is why I have a pre-paid card

When I buy stuff from small online retailers, I use a pre-paid card, because I have no idea who will actually be handling the credit card payment processing, and I don't want to give my real credit card details to a third-party payment site. Pre-paid cards are easy to get hold of, and many of them are free to use after a modest one-off account setup fee.

Mars needs TRAFFIC COP to stop probe prangs, says NASA

David Harper 1

Re: Just add SPICE

It may be easy to calculate a spacecraft position far into the future from a SPICE kernel, but that doesn't mean that the calculated position will be accurate. SPICE is just a data format and a set of subroutines to interpret that data. It's not a panacea for the fundamental difficulty of accurately modelling the orbit of spacecraft around Mars.

I'm guessing that the major stumbling blocks are uncertainties in the gravity field of the planet and the atmospheric drag -- remember that MAVEN is actually sampling the Martian upper atmosphere. Both of these uncertainties severely limit the accuracy of a long-term ephemeris of a spacecraft in an orbit like MAVEN's.

Re: Please try to get the facts right

It's not the orbit. I've read the original paper in Science, and this is the area in which I got my Ph.D. Trust me, it's not the orbit. It's the rotation.

Please try to get the facts right

"The team used data from Cassini to build a 3D model of the moon's orbit and found it wobbles twice as much as it ought."

Not its orbit. They built a 3D model of Mimas itself, using surface features as landmarks. Then they used those landmarks to track subtle changes in the satellite's rotation.

I'd expect this kind of sloppy reporting in a tabloid, but the Register really should aim for a higher standard of scientific accuracy.

ECCENTRIC, PINK DWARF dubbed 'Biden' by saucy astronomers

David Harper 1

Re: You can't name astronimical objects after politicians

The IAU rules (http://www.iau.org/public/themes/naming/) are quite clear about pandering to politicians:

"The names of individuals or events principally known for political or military activities are unsuitable until 100 years after the death of the individual or the occurrence of the event."

So Joe Biden can't have an asteroid named after him until he's been pushing up the daisies for a century.

You can't name astronimical objects after politicians

I very much doubt that the astronomers will succeed in naming it Biden, because the International Astronomical Union has a policy which explicitly forbids naming of astronomical objects after politicians.

Reg tries out Google's Chromecast: Yep, we even tested smut sites

Way better than Virgin Media TiVo for BBC iPlayer

I bought a Chromecast via Amazon this week to find out whether it would help me to escape from Virgin Media TiVo / BBC iPlayer hell. In short, VM's TiVo system cannot play on-demand TV using the BBC iPlayer. The video stream glitches every few seconds, making it pretty much unwatchable. According to the VM engineer who came to check our newly-installed TiVo after I complained about the crap iPlayer video quality, this is apparently a known problem, but neither Virgin nor the BBC will admit responsibility.

Anyway, I'm happy to report that Chromecast solves the problem. I can now cast BBC iPlayer video streams from my smartphone or tablet to my TV, and the quality is excellent. Thank you, Google.

UK.gov recruiting 400 crack CompSci experts to go into teaching

What about the kids who have no aptitude for programming?

Nobody has mentioned the elephant in the room -- not everyone has an aptitude for programming, just as not everyone has an aptitude for maths, or languages, or music.

Some years ago, Richard Bornat (a computer science professor at Middlesex University) and his graduate student Saeed Dehnadi did research which demonstrated that in their class of first-year computer science undergraduates, there were two distinct groups: those who intuitively understood how to write programs, and those who didn't. Worryingly, the performance of the second group could not be significantly improved by training them. This was published as a paper titled "The camel has two humps". (You can find it by googling the title.)

Now Gove wants to try to force school kids to write computer programs, when most of them will have neither the interest nor the aptitude for it. It's a recipe for disaster.
