Reporting errors in Google Maps used to be fairly simple, if you knew how, but the constant changes in the UI makes it difficult. When they first introduced bicycle maps, there were quite a few grave errors initially (up/down a stairway, along a motorway where bicycling is prohibited). They were fixed pretty soon after I reported them.

After messing around in Maps for a while (web version), I see that it's still easy enough to report errors. Just click the speech bubble.

Comment Re:Grades vs IQ (Score 1) 391

Lots of people with high IQ are far from brilliant. It's only a test result, it doesn't tap into your brain. The supposed verification of an IQ test is actual academic achievement; when high IQ people have low academic achievement, it might just as well mean the test is flawed.

Comment Re:So you can reuse the PC board? (Score 1) 122

It's a similar problem. Except since this is a much larger connector(100 times as many pins?) with smaller pins(1/4 the size?) and uses a specification that is used by far fewer people than USB it's MANY MANY times more likely to have an issue than a single USB port.

In reality computers solder USB all the time for lower-bandwidth devices(e.g. Bluetooth, WebCam, SD reader, InfraRed, ethernet, WiFi, etc). It's dramatically cheaper and slightly more reliable than including a full USB port because you don't have to worry about charging phones(1000ma+) on a port that will only have a 250ma device on it or buy all the interconnects. The actual chips for most of this stuff are pennies. To build the same thing with interchangeable interconnects raises the power budget, the component budget, and the QA budget...

It's "Hiroshima" ,and you really ought to read up on the details before commenting.

Roughly 80K were killed INSTANTLY from the blast. Blown to bits, vaporized, incinerated, or rather more prosaically by killed shrapnel. Others were killed when the city burned - lots of wooden construction, especially far from the city center. Many more were fatally wounded but did NOT die in the blast - burn or shrapnel victims who would die of infection or lack of treatment days, or even weeks later. The fatality list would have been smaller had the bombing not eliminated most medical staff and facilities within the city, leading to treatable wounds becoming septic.

You can't take the total fatalities, subtract the immediate deaths and arrive at the figure for "death by radiation poisoning". In point of fact, there were a great many people killed from radiation, but anyone close enough to the blast to receive a lethal dose ALSO received other injuries, meaning that, rather than having discrete categories for radiation poisoning, burns, shrapnel/blast and infection casualties, you have people who were wounded in multiple ways, and died of more than one cause.

Limited demand. They'd be selling a product that's both low quality and illegal to own. The target market for that would be criminals with money to spend, who don't already have access to equal or better guns. And it's not like you can set up shop on a street corner; secrecy is expensive.

Basically, a black market Sten Gun factory has all the drawbacks of illegal arms dealing AND startup costs to boot. I'm not surprised it isn't a thing yet. Oh, and I doubt 3D printing will make it a reality any time soon - the startup costs would be lower, but the 3D printed guns would be even worse than cheap locally manufactured metal guns.

There are places in the world where the locals make cheap metal guns en masse, but they tend to be places like Chechnya rather than the UK.

Who is actually raising these concerns?

The main quote comes from a teacher who works for a think tank(that needs funding) talking about conversations he had with other teachers... not stuff he's done himself.

"I've spoken to a number of nursery teachers who have concerns over the increasing numbers of young pupils who can swipe a screen but have little or no manipulative skills to play with building blocks – or pupils who can't socialise with other pupils, but whose parents talk proudly of their ability to use a tablet or smartphone."

Comment Re:Enjoy it while it floats (Score 4, Informative) 66

When underground radioactive elements decay, helium is a byproduct (look up "alpha particle radiation"). Because it's a noble gas and doesn't bond with anything, it seeps its way to the surface, where it escapes into the upper atmosphere. Some helium can instead become trapped by non-porous rock, in underground pockets. Those same pockets sometimes have natural gas deposits.

So you find a natural gas deposit, tap it, and what comes out as well? Helium. It's not the main product they're after when they go drilling, but it is valuable enough to set aside and sell.

Few adults can hear sounds above 18kHz. I remember making tone generators in Pascal as a kid, beeping out audible 22kHz notes that my older brother and my dad couldn't hear. Later on, I'd try similar programs on my mobile phone, but the damn device couldn't generate tones above 16.5kHz. Poor hardware, I thought, until I tried it on my 16 years old nephew.

Grasshoppers aren't nearly that high pitched.
