Ask Slashdot: When and How Did Europe Leapfrog the US For Internet Access?

pjt33 Re:Government Intervention (469 comments)

The US wasn't the first adopter of mobile telephony. Japan and a group of European countries got there first. And the major carriers in the US no longer support the first system, so there's no good reason to be "stuck with" the mistakes.

Scientists Determine New Way To Untangle Proteins By Unboiling an Egg

pjt33 Re:Boiled at 90C? (155 comments)

0[F] = "It's really cold out there".

I think that should say 68F. At least the phase changes of water are relatively objective.

Iran Forced To Cancel Its Space Program

What I'd like to see in the abstract is an explanation of what the submitter thinks "ironically" means. Maybe Mark Whittington is Alanis Morrisette's alias.

To Avoid Detection, Terrorists Made Messages Seem Like Spam

pjt33 Re:Drone Strikes Against Spammers ? (110 comments)

People have been talking about using spam for steganography for a long time too. spammimic.com predates 9/11, and I'm not even sure it's the earliest example.

Education Debate: Which Is More Important - Grit, Or Intelligence?

UK Computing Teachers Concerned That Pupils Know More Than Them

pjt33 Re:WHY so they not have a masters degree?? (388 comments)

Because for some strange reason a masters degree in computing wasn't considered necessary to teach 5-year-olds when they started their careers. Crazy, isn't it?

UK Computing Teachers Concerned That Pupils Know More Than Them

pjt33 Re:To be fair... (388 comments)

There's another fairly major point: although the title of this /. thread talks about "computing teachers", the summary talks about "primary and secondary teachers", and the original press release talks about "teachers responsible for teaching computing". Primary school teachers, who were already expected to know everything about everything, are now (PDF warning) expected to teach programming, debugging, networking, etc. There's no particular reason why people who signed up to teach 5 to 7 year-olds ten years ago would be more likely than the general populace to be good at debugging.

Education Debate: Which Is More Important - Grit, Or Intelligence?

pjt33 Re:The Full List (249 comments)

As the parent of a Straight ‘A’ gifted child I can say for a fact Hard Work is the most important factor.

As a former straight A gifted child, I can say that you're wrong. Maybe hard work is the most important factor for your daughter, but you can't extrapolate from her to every successful student.

The only year in my education in which I worked hard was my first year at university, partly because I didn't know how good I was relative to my peers and wanted to compete, partly because a quarter of my course was material which I did actually need to work at, and partly because my one-on-one for that material was with someone who really pushed me. When I finished in the top three and won a scholarship, I didn't feel the need to prove myself in the second and third years, and I had more freedom to choose courses which I found easy. The most important factors for my academic success were intuition, a memory which was good at retaining the things that matters for the subjects I chose, and curiosity.

Just to be completely clear: I'm not knocking hard work. The person who finished first in my course in the second year was a friend whom I met up with once or twice a week to explain the things they hadn't understood in lectures. I think they worked quite hard, and maybe I could have finished first if I'd worked harder. But I preferred to spend about twenty hours a week working and have lots of time to participate in various student societies, because university is about more than grades. (I still got first class honours, so I didn't judge it too badly!)

Analysis of Spacecraft Data Reveals Most Earth-like Planet To Date

pjt33 Parameter mismatch (83 comments)

5737.01 ... is 30% larger than Earth, Mullally says. That’s good news, because scientists here reported yesterday that planets more than 1.6 times the mass of Earth are unlikely to be dense rocky worlds like ours

I'm not seeing the good news. If it has a similar density to Earth, it will have a mass about 1.3^3 ~= 2.2 times the mass of Earth.

Being Colder May Be Good For Your Health

pjt33 Re:Yay! Statistics! (234 comments)

I wish the article said something about which parts of Spain, because with the exception of the Pyrenees it doesn't really make sense to talk about the "warmer parts" versus the "cooler parts". There are the parts which have much more seasonal variation - and so are warmer in summer and cooler in winter - and the parts which are more moderate all year round. This is influenced by altitude and proximity to the coast, so probably also has a good correlation with humidity. And I'm sure there are even more confounding factors which could be added to the list.

Like, I'd be making money on every transaction since it uses my app, and my app's purpose is solely to connect riders to drivers, but I wouldn't be the one supplying the vehicles or drivers.

They'd get you for conspiracy instead.

Mathematical Trick Helps Smash Record For the Largest Quantum Factorization

pjt33 Re:... break most modern cryptographic codes? (62 comments)

I think GPP was talking about the generic comments made on quantum computing rather than the particular analysis which is the main topic. Shor's algorithm does discrete log as well as factorisation.

I rather hope that it requires that the bits which flip are next to each other, because otherwise they've overlooked 16843009 = 257 * 65537, the product of the two largest known Fermat primes.

Ocean currents proposed as cause of magnetic field

pjt33 pjt33 writes  |  more than 5 years ago

pjt33 (739471) writes "The Institute of Physics reports a recently published paper which proposes that ocean currents could account for Earth's magnetic field. The currently predominant theory is that the cause is molten iron flowing in the Earth's outer core. There is at present no direct evidence for either theory."
