The issue is the particulate filters that are nowadays standards seem to be worse for your health: particles are so thin you can't see them anymore (hence no more belch smoke) but they're also so thin they can now enter your bloodstream more easily.

The issue is that there were always fine particulates, and they can't be trivially filtered out. But perhaps you missed it when we discussed here that gasoline engines produce as much soot as diesels, and it is all of the exceptionally-fine kind. Now that the big stuff is being filtered out of the diesel exhaust, all we have left is a relatively small amount of that PM2.5.

Ideally we'd do away with the ICEs entirely and eliminate all that crap, get down to worrying about how to eliminate it from the tires. But what's really pathetic is that we've had the technology at least since the 1800s to solve all of these problems. It's called electrified rail. With modern levels of traffic, it is worthwhile to have people in packets smaller than train cars, however, yet with the distances which must be covered the vehicles must have their own power storage. Current battery and self-driving vehicle technology permits just this particular use case. We have every piece we need to replace cars entirely with PRT save for the will, starting in the densest city centers and moving outwards in stages related primarily to the availabilty of parking.

AHEM. Back on topic. "invisible smoke doesn't mean it's better" is exactly why diesel is better than gasoline. And yet, soot isn't even the worst emission that cars produce! It's unburned hydrocarbons, also known as raw fuel. And by their nature, diesels which are running properly run lean all the time, that's just how they operate. That means they're burning their fuel. It also means they produce more NOx, but that's why diesels now have catalysts.

They are also heavier and more expensive. Nothing comes for free.

It does if you're subaru and you've got opposed cylinders and thus it doesn't have to be heavier, and the whole world is moving towards turbocharged gasoline direct injection anyway which means the engines cost just as much as diesels. and guess what? they foul their intake valves more than diesels do! hilarity ensues.

Granted it is not the cleanest fuel.

It is the cleanest fuel. We discussed here on slashdot how (gasoline-driven) cars emit more black carbon than previously thought) and the diesels are more efficient so you actually wind up with diesel as the cleanest fuel once you get the traps and filters and piss injection and whatnot. It's true that gasoline direct injection is close, but it's also true that it takes less energy to make diesel than gasoline, that diesel contains more energy than gasoline per liter, and that diesel is less volatile and thus less hazardous to transport and store than gasoline. All in all, it is the superior fuel. Also, it can be made from biological feedstocks including oils from algae, waste animal fats, and so on, and with proper seals and fuel line linings mixed to any proportion with petrodiesel.

Diesel is a better fuel than gasoline in every single way. If, like Subaru, you build your diesel with opposed cylinders, it doesn't even have to be big and heavy because vibration is inherently cancelled by the design. It's just better. The TGDIs are just as expensive as TDIs. So the only thing wrong with Diesel fuel here in the USA is the taxes, and the only thing wrong with it in France is that they want to get rid of it, probably for a reason mentioned elsewhere in this discussion — it's taxed less there.

Since you are an anonymous coward, your anecdote is worth even less than the usual nothing. Even if your veracity were assured, we have no idea where you are. We know only that you are cowardly, and make both typos and unsubstantiated statements.

Submission + - Hey kids! Banned books! (nytimes.com)

nbauman writes: The Gilbert, AZ school board has voted to tear out a page from Campbell's Biology (a standard highly-recommended textbook that many doctors and scientists fondly remember), because it discusses contraception without also discussing adoption. Julie Smith, a member of the Gilbert Public Schools governing board, said that she was a Catholic and "we do not contracept." Smith convinced the board that Campbell's violates Arizona law to teach "preference, encouragement and support to childbirth and adoption" over abortion. The Arizona Education Department decided that the pages didn't violate Arizona law, but nevermind. Rachel Maddow generously risked hassles for copyright violation and posted the missing pages as a service to Arizona honors biology students. http://www.msnbc.com/rachel-ma...

Single Pixel Camera Takes Images Through Breast Tissue 81

KentuckyFC writes Single pixel cameras are currently turning photography on its head. They work by recording lots of exposures of a scene through a randomising media such as frosted glass. Although seemingly random, these exposures are correlated because the light all comes from the same scene. So its possible to number crunch the image data looking for this correlation and then use it to reassemble the original image. Physicists have been using this technique, called ghost imaging, for several years to make high resolution images, 3D photos and even 3D movies. Now one group has replaced the randomising medium with breast tissue from a chicken. They've then used the single pixel technique to take clear pictures of an object hidden inside the breast tissue. The potential for medical imaging is clear. Curiously, this technique has a long history dating back to the 19th century when Victorian doctors would look for testicular cancer by holding a candle behind the scrotum and looking for suspicious shadows. The new technique should be more comfortable.

Or astrology, or scientology, or anything that has OOGY BOOGY aspects.

Basically Stay away from anything with oogy boogy aspects with one exception, Quantum Entanglement feels very much oogy boogy. but it has been demonstrated as real with real scientific process. It's simply something we do not understand but HAVE PROVEN does exist.

So if it has oogy boogy and no proof of it's existance, run away.

Submission + - Hackers Breach Payment Systems of Major Parking Garage Operator (securityweek.com)

wiredmikey writes: Parking garage operator SP+ said on Friday that an unauthorized attacker gained access to its payment processing systems and was able to access customer names and payment card information. The company, which operates roughly 4,200 parking facilities in hundreds of cities across North America, said the attack affected 17 SP+ parking facilities.

According to the company, an unauthorized person had used a remote access tool to connect to the payment processing systems to install malware which searched for payment card data that was being routed through the computers that accept payments made at the parking facilities.

Parking facilities in Chicago, Cleveland, Philadelphia, Seattle, and Evanston were affected by the breach, though a majority of the locations affected were located in Chicago.

SP+ did not say what type of malware was found on the systems. Earlier this week, a new strain of point-of-sale malware targeting e-kiosks and ticket vending machines was uncovered by intelligence firm IntelCrawler. Dubbed 'd4re|dev1|', the malware is hitting mass transit systems, and acts a backdoor that gives attackers remote administration capabilities.

AMD chips need a lot of juice for a given level of performance. Their Vishera chips that competes with Intel's high end desktop i5s in price and in some cases performance (depends on the benchmark, it is as fast in some, woefully slower in others) needs 220 watts to get that level of performance.

If you desire a power economical processor, Intel are your guys. AMD's architecture and lithography are just not up to Intel's level at the moment.

You also have to remember, with regards to lithography, Intel is WAY ahead of anyone else. AMD's chips are still 32nm, these new Broadwell chips are 14nm.

Of all Linux distributions, Debian was *the* first choice for running servers, but since they decided to force systemd down users throats they have lost a lot of credibility in the BOFH world. A sysadmins first concern is reliability of its systems and this was also Debian's for a very long time. Clearly the adoption of systemd is not going in this direction. It seems to me that Devuan people understood that and want to take the now deserted land of server oriented distros. Of course the meaning for Debian is they will now have a hard time to compete with the whole lot of very good desktop distributions if they don't want to lose most of their users.

Then why aren't you hearing anything from the Red Hat customer base? If anyone wants reliability it's the enterprise which is Red Hat's entire market. The fact that nothing is coming from that side tells me that this is about something else entirely where people are more concerned about the political process and symbolism than the technical merits.

Maybe there is a big demand for a very stripped down low feature server distro, but I suspect this isn't going do become a big player.

The rest of EU already has strict laws agat pollution. E.g. that Diesel engines need a filter against particles. Or have laws that only cars allow into the cities that meet certain cleanness requirements.
Paris even had to shut down car trafic last year because of smog. That is very unheared of since decades in europe.
You see very dirty cars in Paris every day, because no one really cared so far.
So, no: the old french cars are not sold into the EU ... it is the opposite around. Like myself: I export my car to france as I can mot use it in my town anymore because it is one glimpse of a fraction above the alowed emissions.
