UK Police Force Posts All Its Calls On Twitter 66

from the 140-crimes dept.
Stoobalou writes "One of the largest police forces in the UK is posting every incident reported to it today on Twitter. Greater Manchester Police began its 24-hour experiment this morning at 05:00 BST, tweeting all incident reports in the hope of highlighting the complexity of modern policing. 'Policing is often seen in very simple terms, with cops chasing robbers and locking them up,' Chief Constable Peter Fahy said in a statement. 'However the reality is that this accounts for only part of the work they have to deal with.'"

Microwave Map of Entire Moon Revealed 82

from the quickest-route-mode dept.
Zothecula writes "The first complete microwave image of the Moon taken by Chinese lunar satellite Chang'E-1 has been revealed. Chang'E-1 is China's first scientific mission to explore planetary bodies beyond Earth and the on-board Lunar Microwave Radiometer has made it possible for the first time to globally map the Moon in microwave frequencies. Radar observations of the Moon are unable to provide thermal information, and microwave observations taken from Earth cannot reach the far side of the moon. So Chang'E-1's (CE-1) orbit was conducted at an altitude of 200km (124 miles) and allowed it to observe every location of the moon with a nadir view and at high spatial resolution."

State Senator Caught Looking At Porn On Senate Floor 574

Everyone knows how boring a debate on a controversial abortion bill can get on the Senate floor. So it's no wonder that Florida State Sen. Mike Bennett took the time to look at a little porn and a video of a dog running out of the water and shaking itself off. From the article: "Ironically, as Bennett is viewing the material, you can hear a Senator Dan Gelber's voice in the background debating a controversial abortion bill. 'I'm against this bill,' said Gelber, 'because it disrespects too many women in the state of Florida.' Bennett defended his actions, telling Sunshine State News it was an email sent to him by a woman 'who happens to be a former court administrator.'"

Disputed Island Disappears Into Sea 460

RawJoe writes "India and Bangladesh have argued for almost 30 years over control of a tiny island in the Bay of Bengal. Now rising sea levels have ended the argument for them: the island's gone. From the article: 'New Moore Island, in the Sunderbans, has been completely submerged, said oceanographer Sugata Hazra, a professor at Jadavpur University in Calcutta. Its disappearance has been confirmed by satellite imagery and sea patrols, he said. "What these two countries could not achieve from years of talking, has been resolved by global warming," said Hazra.'"

Still, like any stable dictatorship, China is able to pursue at least some general, strategic long-term plans. It's the advantage of rulers who don't have to worry that they're leaving the office in a few years, like in democracies where most presidents/governors/mayors won't bother to lay any eggs that will only hatch after their mandate is finished (especially when reelection is not allowed).

As a former Z80 black-belt ninja, I'd say it was easier - except that Z80 didn't have mul/div instructions... but, who needs these? You could write a routine for this (granted: dead slow) but I've written pretty significant programs without ever needing a single "full" mul/div, just hacking around it with a couple shifts, adds or bit ops.

...is this: suppose that we make contact with some alien species, and it just happens that they are overwhelmingly superior to us - a civilization that's thousands of years more advanced and kicks our ass in technology, morals, arts, everything.

Now suppose that this civilization is completely atheist. They are angel-like beings but with no God; they consider religion a trait of pre-historic (in their POV) civilizations. Just like, say, our modern opinion about cannibalism. Their scientists and philosophers have long demolished all pro-religion arguments, finishing this debate in such clear terms that any educated human would understand and find impossible to not agree.

*If* this happens (notice I'm just supposing), religion is in major trouble and the only option for resistance is fanatism.

It was once believed that the sun revolved around the earth. This is still a good approximation, for most purposes here on the ground. It is only when we begin to consider the motion of other planets that it becomes important which is which.

Actually, saying that the Sun orbits Earth is not really wrong even today. The universe doesn't have a fixed reference frame so no body has an absolute position, all 'positions' are just relative to other bodies (including time positions). We still tend to put the Sun in the "center", in coordinate (0,0,0) of the solar system, because that's very useful for local purposes, but it's just as arbitrary as having Earth in the center centuries ago. So, we could very well define as a convention that Earth is permanently fixed in the center of the entire Universe as a convention, and adjust all our calculations for that, and everything would be just fine... some equations could become more complex (a microscopic perturbation in Earth's orbit would translate, due to angular distance, in galaxies billions of years away being "shaked" in faster-than-light speed - still not violating any physics laws) but that would be just complex and ugly, not wrong.

...formed one billion years ago, but originally much more distant from the star. But its orbit was not stable, approaching quickly (in astronomical time) to the star; and we're just lucky to have found it in the final stage of the death spiral. If this is the case, it may even be possible to watch the final spectacle in a timeframe reasonable for human scale (a few thousand years, perhaps centuries, or even less).

Wild speculation of course... but just to be safe, I'm immediately canceling all my plans of space vacations near the Wasp18 system. I never liked wasps anyway.

...as the latest JVMs have a "compressed pointers" option that allows the 64-bit VM to be as memory-efficient as 32-bit. This option limits max heap size to 32Gb, but this should be plenty for even most huge applications, for many years to come.

BTW this optimization is a great advantage of all "managed" languages/VMs; it's just impossible for langs like C/C++. Of course, you've got to actually implement it in a JIT compiler like Java's. But I think even an interpreter could do it. Notice that there is no tradeoff to code speed; although the code needs a couple extra instructions to compress/uncompress pointers at every usage of heap objects, this overhead is greatly reduced/hidden by JIT optimizations. (And for an interpreter, it's certainly just noise in the performance map.) Not to mention that the gains in reduced paging, cache misses and TLB misses will more than compensate for any remaining overheads.

L4 is a microkernel, so it DOES mean that buggy device drivers cannot crash, corrupt, DoS or own the system; because drivers would all run in userland.

Of course, if bugs prevents that some essential driver works at all, the system may becomes unusable anyway. But the kernel is still in control and it can resort to techniques like restarting the driver or, if the driver keeps failing, replacing it by a much simpler, "safe mode" driver so you can use the system even with some reduced functionality or performance.

Who in his right mind starts mixing a binary and a decimal system. 2^10 bytes?

Very likely, a hardware engineer or a programmer who had to deal with low-level system realities like memory block sizes being always powers of two. You must manipulate memory (and other HW things) in blocks which sizes match physical packaging, to avoid inefficiencies from alignment, memory hierarchies, etc.

And this is reality up to current day. Please come back whining for decimal system when you're using, say, a monitor with 1500x1000 resolution, or a net connection of 10.000.000 bps.

I for one, will continue using Kb = 1024 etc., these politically correct labels like KiB are for idiots.

Information is the inverse of entropy.
