Submission + - Cleaning Products a Big Source of Urban Air Pollution, Say Scientists (

An anonymous reader writes: Household cleaners, paints and perfumes have become substantial sources of urban air pollution as strict controls on vehicles have reduced road traffic emissions, scientists say. Researchers in the US looked at levels of synthetic “volatile organic compounds”, or VOCs, in roadside air in Los Angeles and found that as much came from industrial and household products refined from petroleum as from vehicle exhaust pipes. The compounds are an important contributor to air pollution because when they waft into the atmosphere, they react with other chemicals to produce harmful ozone or fine particulate matter known as PM2.5. Ground level ozone can trigger breathing problems by making the airways constrict, while fine airborne particles drive heart and lung disease. Writing in the journal Science, De Gouw and others report that the amount of VOCs emitted from household and industrial products is two to three times higher than official US estimates suggest. The result is surprising since only about 5% of raw oil is turned into chemicals for consumer products, with 95% ending up as fuel.

Submission + - Blaming YouTube or the FBI for Yesterday's School Shooting Tragedy Is Wrong (

Lauren Weinstein writes: Before the blood had even dried in the classrooms of the Florida high school that was the venue for yet another mass shooting tragedy, authorities and politicians were out in force trying to assign blame everywhere.
That is, everywhere except for the fact that a youth too young to legally buy a handgun was able to legally buy an AR-15 assault-style weapon that he used to conduct his massacre.

Much of the misplaced blame this time is being lobbed at social media. The shooter, whom we now know had mental health problems but apparently had never been adjudicated as mentally ill, had a fairly rich social media presence, so the talking heads are blaming firms like YouTube and agencies like the FBI for not “connecting the dots” to prevent this attack.

Submission + - Researchers automate Spectre exploits, find additional side-channel

ffkom writes: In a new paper MeltdownPrime and SpectrePrime: Automatically-Synthesized Attacks Exploiting Invalidation-Based Coherence Protocols researchers describe an automated tool to write exploit code for Spectre-type attacks, tailored to different CPU architectures.

While using their tool, they also identified another side-channel that can be used for a new Spectre-variant they call "SpectrePrime": Instead of using speculative reads to fill caches, they use speculative writes that cause detectable changes to cache states, even when ultimately not executed.

In other news, one of the original Spectre researchers found Microsoft's compiler changes to mitigate Spectre type-1 attacks to be largely ineffective.

Submission + - Bloomberg is now tracking Model 3 production (

WindBourne writes: Tesla is producing their model 3, but is apparently tried of answering critics about production.
So, they quit telling.
Now, bloomberg has an active tracker that shows the total production and delivered, along with the production per week, which is probably more important.
In fact, they are now up to 1025 model 3s / week, and it is apparent that Tesla is growing by leaps and bounds on this as parts of the manufacturing line is converted to full robotics.

Submission + - France's Telecom Regulator Thinks Net Neutrality Should Also Apply To Devices (

An anonymous reader writes: The ARCEP, France’s equivalent of the FCC in the U.S., wants to go beyond telecommunications companies. While many regulatory authorities have focused on carriers and internet service providers, the French authority thinks Google, Apple, Amazon and all the big tech companies also need their own version of net neutrality. The ARCEP just published a thorough 65-page report about the devices we use every day. The report says that devices give you a portion of the internet and prevent an open internet. “With net neutrality, we spend all our time cleaning pipes, but nobody is looking at faucets,” ARCEP president Sébastien Soriano told me. “Everybody assumes that the devices that we use to go online don’t have a bias. But if you want to go online, you need a device just like you need a telecom company.”

Now that net neutrality has been laid down in European regulation, the ARCEP has been looking at devices for the past couple of years. And it’s true that you can feel you’re stuck in an ecosystem once you realize you have to use Apple Music on an Apple Watch, or the Amazon Echo assumes you want to buy stuff on when you say ‘Alexa, buy me a tooth brush.' “The interface of the smartphone makes it much more comfortable than a computer,” Soriano said. “But they’re holding your hand — the size of the screen means that they don’t show you as many things.” And smartphones are just the tip of the iceberg. Voice assistants and connected speakers are even less neutral than smartphones. Game consoles, smartwatches and connected cars all share the same issues. The ARCEP doesn’t think we should go back to computers and leave our phones behind. This isn’t a debate about innovation versus regulation. Regulation can also foster innovation. “This report has listed for the first time ever all the limitations you face as a smartphone user,” Soriano said. “By users, we mean both consumers and developers who submit apps in the stores.”

Submission + - Windows 10 Is Adding An Ultimate Performance Mode For Pros (

An anonymous reader writes: When you're creating 3D models or otherwise running intensive tasks, you want to wring every ounce of performance out of your PC as possible. It's a good thing, then, that Microsoft has released a Windows 10 preview build in the Fast ring that includes a new Ultimate Performance mode if you're running Pro for Workstations. As the name implies, this is a step up for people for whom even the High Performance mode isn't enough — it throws power management out the window to eliminate "micro-latencies" and boost raw speed. You can set it yourself, but PC makers will have the option of shipping systems with the feature turned on. Ultimate Performance isn't currently available for laptops or tablets, but Microsoft suggests that could change.
