Comment Re:Jet engines?? (Score 2) 175

IANA aerospace engineer but I got a different feeling from the lillium website and the video they are linking from the top page about the flight of their full scale prototype. There are also graphics showing the engines pointed straight back. They are mounted on tilting flaps so they would be pointed down at low speeds such as in the test flights.

Perhaps it is not really a jet engine but if these compressors are mounted on tilting flaps I would expect them to be facing straight back at cruising speed.

In 2009 I delivered a supply chain system to a major construction equipment manufacturer. Even one hour of downtime for these machines is very expensive so people would be cannibalizing other machines to make a quick fix. They already had a satellite-based telemetry system in place to predict failures and servicing, and our system checked different warehouses and tried to pick the best choice based on various rules including lead time calculation. This article is talking about something that other companies have already done for years now.

Comment Humans needed but there are some solutions (Score 1) 124

There are some things that will work.
A major provider carries email for a lot of people and can tell if mail is spam if
- the people have no intersecting interests
- they mostly receive it at the same time
- a number of users mark it as spam (nearly all users who regularly mark anything as spam)
Google is obviously doing this and some other for-pay providers too, is my guess. I'd pay for a way to be able to test my email headers against such a service without actually running my email through their servers.

Also, you can hire people to actually read email subject lines and decide whether email is spam. Probably a small number of people could make a huge difference and I'd propose that the cost of such a system could easily be borne by government, or be covered by a very low fee.

As first line of defense, you can make a someone lenient automatic system that blocks out common keywords/patterns in email. This would probably cover 98% of spam and could be tweaked by an end user (for example anything about Trump, CNN, gambling, Gwen Stefani or hot tubs is spam 100% for sure). A central repository for such keywords/patterns could be very useful to end users. Personally I have a number of accounts some of which are old and combined they send me a huge amount of spam, so I am considering what to do about it. The above would be a big help.

Comment But my 2TB SSD Mac rocks (Score 1) 167

Makes me even happier about my recent purchase!
A lot of mac haters and people saying SSD are unreliable, etc. Guess what, even the touch bar is way better than I would have expected based on the flames on Slashdot.

Well I have lost 1 or 2 files in the past on my 2009
MBP 17in which I loved, despite the weight, until the HDD errors started piling up. I use Windows and run some linux servers too. The price was quite high but I configured the best model I could since I expect to get 5-10 years of use out of it. I know 500gb was not enough to hold 5 years of cruft and VMs. This is my first SSD and surprised to hear how brittle people find them, so will do some research and set up some local storage. I remember a video studio that often had HDDs fail so thought SSD would be more reliable.

It would be more useful to me to hear what mac users recommend for backups - a tethered drive set up for time machine? Or one set up as a bootable backup with Carbon Copy Cloner? Or a local linux box and rsync? Ideally I'd like a fine granularity versioned backup that combines these worlds.

Pretty amazing the number of highly scored posts promoting autodarwination of own species. In other words voting *against* safety measures for an acknowledged safety issue. Personally I think a flashing fullscreen big red icon that displays in response to broadcast danger signals would be better but seriously traffic accidents from people ultrafocused on data has got to be one of the bigger threats to readers.

Submission + - Malware Researchers Discover Russian Banks Talking to Trump's Private Servers (

ewhac writes: After news broke of Russian hackers infiltrating the Democratic National Committee's servers, malware researchers decided to see if other politically-motivated intrusions were taking place. Among others, they monitored DNS traffic relating to the Trump Organization, looking for evidence of intrusion. Instead, they discovered traffic from Russia that did not match the patterns typical of malware or botnets. Rather, the patterns looked like ordinary human-driven traffic, as one might expect from email being exchanged between servers — specifically, from servers operated by Russia's Alfa Bank. Further, Trump's server only accepted connections from a limited number of IP addresses. Even more curious, when the malware researchers reached out to Alfa Bank to inquire about the unusual traffic, but before speaking to the Trump campaign, the DNS entry for Trump's server was clumsily deleted. As one researcher put it, "The knee was hit in Moscow, the leg kicked in New York." Four days later, the Trump Organization registered a new DNS name for the same server; the first DNS lookup for that name came from Alfa Bank in Russia. While the evidence is not conclusive, it is undeniably suggestive that Trump has more than just an "arms-length" relationship with Russia, and warrants further investigation.

Submission + - People Who Use Facebook Live Longer, Study Finds (

An anonymous reader writes: Study after study has demonstrated a link between strong social connections and reduced mortality risk. But does that hold true as our social interactions increasingly take place in online spheres? A new study out of Yale and the University of California suggests that it does. The study, published today in the journal Proceedings of the National Academy of Sciences found that people who use Facebook live longer than those who do not, and that certain types of Facebook activities — like posting pictures and accepting friend requests — are associated with a lower risk of mortality. "There's a big debate about online social media. There are people that worry that worry it substitutes for healthy social interaction,"co-author James Fowler, a social scientist from University of California, San Diego, told CBC News. The researchers started with 12 million Facebook profiles, then narrowed it down to four million people whose identities could be verified through California's voter registration list. Then they used data from the California Department of Public Health to compare those people to voters who don't use the social networking platform. They found the risk of dying in a given year was 12 per cent lower for Facebook users than non-Facebook users. That doesn't mean Facebook is necessarily good for you, Fowler cautions. Correlation does not prove causation, so it's impossible to say whether being on Facebook makes you healthier, or whether healthy people are more likely to be on Facebook. Still, Fowler said the study does help debunk some of the negative associations people have with social media. "The fact that we found such a strong positive relationship between health and social networks speaks against the hypothesis that they're making us unhealthy in some way," he said.

Submission + - Physicists Induce Superconductivity In Non-Superconducting Materials (

An anonymous reader writes: Researchers at the University of Houston have reported a new method for inducing superconductivity in non-superconducting materials, demonstrating a concept proposed decades ago but never proven. The technique can also be used to boost the efficiency of known superconducting materials, suggesting a new way to advance the commercial viability of superconductors, said Paul C.W. Chu, chief scientist at the Texas Center for Superconductivity at UH (TcSUH) and corresponding author of a paper describing the work, published Oct. 31 in the Proceedings of the National Academy of Sciences. The research, demonstrating a new method to take advantage of assembled interfaces to induce superconductivity in the non-superconducting compound calcium iron arsenide, offers a new approach to finding superconductors that work at higher temperatures. Superconducting materials conduct electric current without resistance, while traditional transmission materials lose as much as 10 percent of energy between the generating source and the end user. That means superconductors could allow utility companies to provide more electricity without increasing the amount of fuel used to generate electricity. To validate the concept, researchers working in ambient pressure exposed the undoped calcium iron arsenide compound to heat — 350 degrees Centigrade, considered relatively low temperature for this procedure — in a process known as annealing. The compound formed two distinct phases, with one phase increasingly converted to the other the longer the sample was annealed. Chu said neither of the two phases was superconducting, but researchers were able to detect superconductivity at the point when the two phases coexist. Although the superconducting critical temperature of the sample produced through the process was still relatively low, Chu said the method used to prove the concept offers a new direction in the search for more efficient, less expensive superconducting materials.

Submission + - AT&T Falsely Claimed Pro-Google Fiber Rule Is Invalid, FCC Says (

An anonymous reader writes: The Federal Communications Commission has given a helping hand to Louisville, Kentucky, in the city's attempt to enforce local rules that would make it easier for Google Fiber to compete against AT&T. AT&T sued the local government in Louisville and Jefferson County in February to stop a One Touch Make Ready (OTMR) ordinance designed to give Google Fiber or other new competitors faster access to utility poles. Today, the US government submitted a statement of interest (full text) on behalf of the FCC, which says that one of AT&T’s primary legal arguments is incorrect. AT&T—also known as BellSouth Telecommunications in Kentucky—argued that the Louisville ordinance is preempted by the FCC’s pole-attachment rules. The local ordinance "conflicts with the procedures created by the FCC, and upsets the careful balances struck by the FCC in crafting its pole attachment regulations," AT&T's lawsuit said. But that is false, the FCC says. The FCC does have rules ensuring reasonable access to utility poles, but states are allowed to opt out of the federal pole-attachment rules if they certify to the commission that they regulate the rates, terms, and conditions of pole attachments. Kentucky is one of 20 states that has opted out of the federal regime and imposed its own rules, the FCC noted. Accordingly, the federal pole-attachment regulations enacted under Section 224 [of the Communications Act] simply do not apply here,” the FCC wrote. More generally, One Touch Make Ready rules are consistent with federal communications policies and regulations that seek expanded broadband deployment, the FCC also wrote.

Google Discloses Exploited Windows Vulnerability 10 Days After Telling Microsoft ( 101

An anonymous reader writes: Google today shared details about a security flaw in Windows, just 10 days after disclosing it to Microsoft on October 21. To make matters worse, Google says it is aware that this critical Windows vulnerability is being actively exploited in the wild. That means attackers have already written code for this specific security hole and are using it to break into Windows systems.In a blog post, security researchers at Google write, "The Windows vulnerability is a local privilege escalation in the Windows kernel that can be used as a security sandbox escape. It can be triggered via the win32k.sys system call NtSetWindowLongPtr() for the index GWLP_ID on a window handle with GWL_STYLE set to WS_CHILD. Chrome's sandbox blocks win32k.sys system calls using the Win32k lockdown mitigation on Windows 10, which prevents exploitation of this sandbox escape vulnerability."

China's New Policing Computer Is Frontend Cattle Prod, Backend Supercomputer ( 69

Earlier this year, we learned about China's first "intelligent security robot," which was said to include "electrically charged riot control tool." We now know what this robot is up to, and what its developed unit looks like. Reader dcblogs writes: China recently deployed what it calls a "security robot" in a Shenzhen airport. It's named AnBot and patrols around the clock. It is a cone-shaped robot that includes a cattle prod. The U.S.-China Economic and Security Review Commission, which look at autonomous system deployments in a report last week, said AnBot, which has facial recognition capability, is designed to be linked with China's latest supercomputers. AnBot may seem like a 'Saturday Night Live' prop, but it's far from it. The back end of this "intelligent security robot" is linked to China's Tianhe-2 supercomputer, where it has access to cloud services. AnBot conducts patrols, recognizes threats and has multiple cameras that use facial recognition. These cloud services give the robots petascale processing power, well beyond onboard processing capabilities in the robot. The supercomputer connection is there "to enhance the intelligent learning capabilities and human-machine interface of these devices," said the U.S.-China Economic and Security Review.
