Another Strike Against the F-35

No Comments
Rather unsurprisingly, it is the logistics and prognostics software, ALIS.

It has not been working right in tests, and even when it does, it means that there is effectively an off switch for any foreign buyer’s aircraft located in the United States.

Now we learn that they are intending to go live with the system before testing its vulnerability to hackers: (Paid subscription required)

The F-35’s Autonomic Logistics Information System (ALIS) will deploy its next major software release—2.0.2—in July, but concerns remain about performance and security. A report by the Director of Operational Test and Evaluation (DOT&E) released in January suggests delayed ALIS software may push back U.S. Air Force initial operational capability (IOC) and that the network’s cybersecurity has become a key concern.

Lockheed Martin’s ALIS program manager, Jeff Streznetcky, says a U.S. Marine Corps exercise at Twentynine Palms, California, in December and an ongoing Air Force test program at Mountain Home, Idaho, offer more representative indications of ALIS’s readiness than the report.

“By all accounts, ALIS performed exceptionally well” at Twentynine Palms, he says, “and the reports I’m getting out of Mountain Home are similar. ALIS is doing its job supporting the warfighter and ultimately turning jets.”

………

Leaked National Security Agency briefing documents confirm China obtained F-35 engine schematics and radar designs after compromising program systems in the mid-2000s. Less attention has been focused on the kind of information routinely moving through ALIS, which may represent the program’s biggest threat surface.

“The Chinese see ALIS as a fantastic opportunity to enhance and improve their own fighter-aircraft capabilities,” says Bill Hagestad, a retired Marine Corps colonel and expert on Chinese cyber competencies. “But ALIS data would also be of considerable operational and strategic value to the Chinese if they were able to take a look at the disposition and laydown of deployed combat aircraft.”

According to a 2015 report by cybersecurity vendor FireEye, it takes 205 days on average for network breaches to be detected. Even if all data are encrypted, content could be inferred through analysis of network traffic patterns. Attackers can remain undetected longer if they are leveraging previously unknown vulnerabilities.

ALIS’s security is not just dependent on Lockheed’s own software and network defenses deployed on the different national and corporate systems ALIS data transits. The system incorporates a number of off-the-shelf component programs to handle logistics management and other functions: This has cut development timescales and lowered costs, but any vulnerabilities in those products become ALIS vulnerabilities.

………

A comprehensive, ongoing cybersecurity testing regime would appear to be a necessity. Yet the DOT&E report states: “The program currently does not plan to conduct cybersecurity penetration testing during the development of this ALIS release [2.0.2], or any future developmental releases, but will instead rely on previous, albeit limited, cybersecurity test results.”

This has not gone over well with cybersecurity experts. “Suggesting that this should be deployed before it’s properly tested and then tested after it’s deployed is backward security,” says Adriel Desautels, founder of penetration-testing specialist Netragard. “I don’t have a word strong enough to describe the level of absurdity involved with that. You can’t possibly deploy something that’s this sensitive and just have blind faith that you won’t get hacked.

Of course, Lockheed-Martin and the Pentagon maintain that they will deal with any potential vulnerabilities as soon as they get a round to it.

They want to get the aircraft into the field and have a large captive market before people realize that the aircraft is an unaffordable dog.

Ship, then fix.

As any computer gamer knows, there is a a whole world of grief that comes from this arrangement.

San Bernardino DA Uses the Chewbacca Defense

No Comments


The San Bernardino District Attorney told a federal judge late Thursday that Apple must assist the authorities in unlocking the iPhone used by Syed Farook, one of the two San Bernardino shooters that killed 14 people in a killing rampage in December. The phone, which was a county work phone issued to Farook as part of his Health Department duties, may have been the trigger to unleash a “cyber pathogen,” county prosecutors said in a brief court filing.

“The iPhone is a county owned telephone that may have connected to the San Bernardino County computer network. The seized iPhone may contain evidence that can only be found on the seized phone that it was used as a weapon to introduce a lying dormant cyber pathogen that endangers San Bernardino’s infrastructure,” according to a court filing (PDF) by Michael Ramos, the San Bernardino County district attorney.

The development represents the first time any law enforcement official connected to the investigation provided an indication, other than links to possible co-conspirators, of what the authorities might discover on the phone. The district attorney’s position comes a week after Jarrod Burguan, the San Bernardino police chief, said there was a “reasonably good chance that there is nothing of any value on the phone.” James Comey, the FBI director, said Feb, 21 that “Maybe the phone holds the clue to finding more terrorists. Maybe it doesn’t.”

The county declined to directly comment. A spokesman, David Wert, told Ars in an e-mail that “The county didn’t have anything to do with this brief. It was filed by the district attorney.” The DA’s office, which did not immediately respond for comment, followed up with a statement to Ars, saying that there is a “compelling governmental interest in acquiring any evidence of criminal conduct, additional perpetrators, potential damage to the infrastructure of San Bernardino County, and in protecting the California Constitutionally guaranteed due process rights of the victims, deceased and living, arising from state crimes committed on December 2, 2015.”

Jonathan Zdziarski, a prominent iPhone forensics expert, said in a telephone interview that the district attorney is suggesting that a “magical unicorn might exist on this phone.”

OK, it might not be an apocalyptic computer virus, it might just be a “magical unicorn”, or some other mythical beast, like a moderate Republican or a humble Frenchman.

This is a level of mendacity that should have the judge issuing sanctions against the DA.  (Some jail time would be nice)

Terrafugia has announced that its flying car will take flight by 2018.

There is a long history of flying cars (or roadable planes), and it never makes it to the mass market:

When will we finally pilot our own flying cars? It’s a question that’s haunted anyone who grew up watching sci-fi classics, and one American company claims they’re coming sooner than you’d think. Terrafugia is building the first-ever unmanned prototype of its TF-X flying car. They claim the vehicle will be ready for testing in 2018 and available for purchase by 2025.

The TF-X hybrid electric flying car looks mostly like a high-tech 4-seat sedan, except it’s equipped with fold-out wings that have twin electric motors on each side. These motors, powered by a 300 horsepower engine, can assume a horizontal position for flight and a vertical position for takeoff and landing. After using propellers to rise into the air (eliminating the need for any kind of runway), the vehicle would be capable of cruising at 200 mph for up to 500 miles.

There would be no need for a driver to have a pilot’s license, given that the car will be semi-autonomous. The driver can simply input the destination and allow the car to steer itself. The vehicle operator will, of course, have final say over whether the car should land in a particular area, and can abort landing at any time if the area seems unsafe.

This has been in the works for a long time, and I am sure that the most of the tech will work as promised.

After all there have been a dozen or so flying cars over the years.

They’ve just never made the leap from prototype to product.

The NSA’s Whiz Bang is Short on the Whiz, and Long on the Bang

The NSA has a metadata analysis program in South Asia that it used to make up a kill list. It is rather unironically called called SKYNET.

Analysis of the results now indicates that it doesn’t work, but drone based terror continues to rain down on innocent civilians:

In 2014, the former director of both the CIA and NSA proclaimed that “we kill people based on metadata.” Now, a new examination of previously published Snowden documents suggests that many of those people may have been innocent.

 Last year, The Intercept published documents detailing the NSA’s SKYNET programme. According to the documents, SKYNET engages in mass surveillance of Pakistan’s mobile phone network, and then uses a machine learning algorithm on the cellular network metadata of 55 million people to try and rate each person’s likelihood of being a terrorist.

 Patrick Ball—a data scientist and the director of research at the Human Rights Data Analysis Group—who has previously given expert testimony before war crimes tribunals, described the NSA’s methods as “ridiculously optimistic” and “completely bullsh%$.” A flaw in how the NSA trains SKYNET’s machine learning algorithm to analyse cellular metadata, Ball told Ars, makes the results scientifically unsound.

 Somewhere between 2,500 and 4,000 people have been killed by drone strikes in Pakistan since 2004, and most of them were classified by the US government as “extremists,” the Bureau of Investigative Journalism reported. Based on the classification date of “20070108” on one of the SKYNET slide decks (which themselves appear to date from 2011 and 2012), the machine learning program may have been in development as early as 2007.

 In the years that have followed, thousands of innocent people in Pakistan may have been mislabelled as terrorists by that “scientifically unsound” algorithm, possibly resulting in their untimely demise.

(%$ mine)

This is why our roving army of flying killing machines is such a bad idea:  If most of the people you kill are innocent, they will have relatives looking to avenge their cowardly assassination.

It’s basic human nature.

Whip Me, Beat Me, Make Me Buy Apple Products

Seriously. If you feel a burning need to be dominated and degraded by a pro, then you clearly need to own the newest iPhone:

Thousands of iPhone 6 users claim they have been left holding almost worthless phones because Apple’s latest operating system permanently disables the handset if it detects that a repair has been carried out by a non-Apple technician.

 Relatively few people outside the tech world are aware of the so-called “error 53” problem, but if it happens to you you’ll know about it. And according to one specialist journalist, it “will kill your iPhone”.

 The issue appears to affect handsets where the home button, which has touch ID fingerprint recognition built-in, has been repaired by a “non-official” company or individual. It has also reportedly affected customers whose phone has been damaged but who have been able to carry on using it without the need for a repair.

 But the problem only comes to light when the latest version of Apple’s iPhone software, iOS 9, is installed. Indeed, the phone may have been working perfectly for weeks or months since a repair or being damaged.

After installation a growing number of people have watched in horror as their phone, which may well have cost them £500-plus, is rendered useless. Any photos or other data held on the handset is lost – and irretrievable.

 Tech experts claim Apple knows all about the problem but has done nothing to warn users that their phone will be “bricked” (ie, rendered as technologically useful as a brick) if they install the iOS upgrade.

Freelance photographer and self-confessed Apple addict Antonio Olmos says this happened to his phone a few weeks ago after he upgraded his software. Olmos had previously had his handset repaired while on an assignment for the Guardian in Macedonia. “I was in the Balkans covering the refugee crisis in September when I dropped my phone. Because I desperately needed it for work I got it fixed at a local shop, as there are no Apple stores in Macedonia. They repaired the screen and home button, and it worked perfectly.”

 He says he thought no more about it, until he was sent the standard notification by Apple inviting him to install the latest software. He accepted the upgrade, but within seconds the phone was displaying “error 53” and was, in effect, dead.

 When Olmos, who says he has spent thousands of pounds on Apple products over the years, took it to an Apple store in London, staff told him there was nothing they could do, and that his phone was now junk. He had to pay £270 for a replacement and is furious.

 “The whole thing is extraordinary. How can a company deliberately make their own products useless with an upgrade and not warn their own customers about it? Outside of the big industrialised nations, Apple stores are few and far between, and damaged phones can only be brought back to life by small third-party repairers.

It appears that Apple’s new motto is, “There is a sucker born every minute.”

After nearly a decade of parallel construction and lying to courts and defense attorneys, the first case regarding whether the use of a cell tower simulator (aka “Stingray”) needs a warrant for its application has made it to a federal appelate court:

A criminal case examining the Fourth Amendment implications of cell-site simulators, also known as stingrays, has finally reached the 7th Circuit for the first time. Now one step below the Supreme Court, this case also likely marks the first time that warrantless use of stingrays has reached any federal appellate court.

Stingrays determine a phone’s location by spoofing a cell tower. In some cases, they can intercept calls and text messages. Once deployed, the devices intercept data from a target phone along with information from other phones within the vicinity. At times, police have falsely claimed the use of a confidential informant while in fact deploying this particularly sweeping and intrusive surveillance tool.

The 7th Circuit will now consider a 2013 case known as United States v. Patrick. It involves a Milwaukee man wanted on a probation violation who was suddenly located and arrested by local police with help from the FBI. There is very strong evidence to suggest that he was apprehended through the warrantless use of a stingray.

Patrick’s attorney, Chris Donovan, filed his opening brief in the appeal earlier this month. The case is so notable that the American Civil Liberties Union (ACLU) and the Electronic Frontier Foundation (EFF) also filed an amicus brief earlier this week. The organizations note that the Fourth Amendment of the United States Constitution requires that search warrants demonstrate probable cause of a crime. And, they note, Wisconsin passed a 2014 state law mandating warrants for stingray deployment.

It’s about f%$#ing time.

Law enforcement has been trying to conceal their warrantless use of this devices, because they are afraid that the courts will require warrants for this.

I hope that their concerns are justified.

It’s not that big deal to get a warrant, but lazy incompetent cops want short cuts.

What a surprise. Chicago cops are actively sabotaging their dashcams:

Why are so many police dashcam videos silent?

 Chicago Police Department officers stashed microphones in their squad car glove boxes. They pulled out batteries. Microphone antennas got busted or went missing. And sometimes, dashcam systems didn’t have any microphones at all, DNAinfo Chicago has learned.

 Police officials last month blamed the absence of audio in 80 percent of dashcam videos on officer error and “intentional destruction.”

 A DNAinfo Chicago review of more than 1,800 police maintenance logs sheds light on the no-sound syndrome plaguing Police Department videos — including its most notorious dashcam case.

 Maintenance records of the squad car used by Jason Van Dyke, who shot and killed Laquan McDonald, and his partner, Joseph Walsh, show monthslong delays for two dashcam repairs, including a long wait to fix “intentional damage.”

 On June 17, 2014, police technicians reported fixing a dashcam wiring issue in police vehicle No. 6412, the squad shared by Van Dyke and Walsh, about three months after it was reported broken, records show.

 A day later, the same vehicle’s dashcam system was reported busted again. It took until Oct. 8, 2014, to complete repairs of what technicians deemed “intentional damage,” according to reports.

 Just 12 days later, on Oct. 20, 2014, dashcam video recorded from squad car No. 6412 on the night Van Dyke shot and killed McDonald did not record audio. The video that went viral showing Van Dyke killing Laquan was taken from a different squad car, but it, too, had no audio.

………

Police officials quickly placed the blame on officers and shift supervisors responsible for making sure dashcam systems work properly before officers go on patrol.

In December, interim Police Supt. John Escalante warned the rank and file that they would be disciplined for failing to follow proper dashcam protocol. Weeks later, he followed through by hitting some officers and supervisors with formal reprimands and up-to-three-day suspensions.

“To boil this down, the Police Department will not tolerate officers maliciously destructing equipment,” police spokesman Anthony Guglielmi said.

Note that there are threats, but when the president of the local police union complains, he does not complain about actual punishments, just the threat of punishment.

This isn’t going to be fixed until someone from the outside excises the rot at the department’s core.

We have another shoe dropping at Theranos Lab:

U.S. health inspectors have found serious deficiencies at Theranos Inc.’s laboratory in Northern California, according to people familiar with the matter.

 The problems were found during an inspection by the Centers for Medicare and Medicaid Services, the chief federal regulator of clinical labs, at the blood-testing company’s facility in Newark, Calif. Failing to fix the problems could put the Theranos lab at risk of suspension from the Medicare program.

 The inspection results are expected to be publicly released soon, these people said. A spokesman for the agency said it “can’t confirm any survey conclusions or results at this time.”

 ………

 Theranos already has stopped collecting tiny samples of blood from patients’ fingers for all but one of its tests while it waits for the Food and Drug Administration to review the company’s applications for wider use of the proprietary vials called “nanotainers.” In October, the FDA said it had determined that the nanotainers were an “uncleared medical device.”

 Since then, Theranos has been performing just one test—to detect herpes—using its proprietary Edison device, people familiar with the matter said. That test was approved by the FDA.

 Theranos is using traditional machines for the rest of the more than 200 tests it offers to consumers, the people said.

Theranos has been a hawking a proprietary technology which allows for a wide range of blood tests to be conducted by a simple finger prick.

They have a valuation of over $1 billion, their technology does not work reliably. their conventional lab tests have been cited by the FDA, and most of their business they have to outsource at a loss.

I understand that this Might Be a promising technology, but how does this become a multibillion dollar valuation?

How is there difference between this and much of the rest of the froth in Silicon Valley?

There are no venture capitalists.  There are just con men looking for the next idiot.

*In the world of business, a unicorn is a company, usually a start-up that does not have an established performance record, with a stock market valuation or estimated valuation of more than $1 billion.

How the Internet of Things Will Actually Be Used

It will be invading our privacy and discrimination, all while presenting it as a benefit to the consumer.

You might want to check out this bit of propaganda from the insurance industry courtesy of the Washington Post, and imagine what they would do if they knew what food was in your fridge, or how often you drink, or what you set your thermostat to.

The term to describe this is “dystopian”:

For years, insurance companies have used estimates of your annual mileage to determine your car insurance rates. But with recent changes in technology, insurers now have an unprecedented ability to judge your actual driving habits. Armed with detailed data on how often you slam on the brakes and what times of day you’re on the road, insurance companies are increasingly relying on precise, technological means of assessing risk — and using that information to set your monthly premiums.

Liberty Mutual, the country’s third-largest property-and-casualty insurer, took the latest step in that direction Monday when it announced a partnership with Subaru. Beginning later this year, Subaru drivers who have paid for the automaker’s Starlink infotainment system will be able to download an app to their cars that notifies them when they are accelerating too aggressively or braking too hard.

The app is part of Liberty Mutual’s RightTrack program, which gives drivers a 5 percent discount on their rates for enrolling and additional discounts up to 30 percent for heeding the app’s guidance on driving safely.

Liberty Mutual, which began offering RightTrack in 2012, isn’t the only insurer to embrace usage-based insurance — a tactic that draws on a person’s real-world driving behavior to gauge his accident risk. Progressive, Allstate and State Farm operate similar programs, too.


.………

But as more Americans begin buying high-tech, connected cars that can talk to the Internet, other analysts say the rise of usage-based insurance raises uncomfortable questions for consumers and insurance companies alike.

“Don’t assume this is always going to be a way to lower your rates,” said Karl Brauer, an analyst at Kelley Blue Book. “It could be used against you to raise your rates long before you ever have an accident.”

Although many insurance companies say that agreeing to be tracked can only result in a discount, not a rate hike, those terms could always change in the future, Brauer and other analysts say. And people who drive safely one year but more riskily the next could effectively see their rates rise when an insurer decides to grant a smaller discount than before.

Then there’s the matter of consumer privacy. How long insurance companies can hold onto your data, and whom they can share it with, depends on each firm’s policies as well as state or local regulations. Insurers would also have to obey court orders for user data.But as more Americans begin buying high-tech, connected cars that can talk to the Internet, other analysts say the rise of usage-based insurance raises uncomfortable questions for consumers and insurance companies alike.

Consumers who don’t want to be tracked don’t have to sign up. But when such programs become more common, opting out could serve as a “red flag” to insurance companies, according to Renee Stephens, vice president of U.S. auto quality for J.D. Power and Associates.

Insurers find behavioral monitoring attractive because it provides them with a clearer picture of the entire risk pool. By understanding better how each driver behaves, companies can design insurance plans that match a person’s risk more accurately and determine how much coverage a given driver requires.

Yes, just trust the insurance companies with your data, allow them to apply opaque algorithms to their systems, and the consumer will always benefit.

Yeah, sure, and Donald Trump does not have a comb over.

The insurance companies will use this to f%$# us like a drunk sorority girl.

How Did This Company Get Any Backers?

Looks Like VC Pump and Dump Bullsh%$to Me

In the continuing revelations regarding the Silicon Valley-eaque medical startup, I have come to the conclusion that it’s investors, and its market cap, are more a product of its founder is an earnest attractive blond who dropped out of Stanford.

First it was repeated reports that their technology failed to work even in highly scripted dog and pony shows for potential investors, now we discover that the company was doing of this while using regulatory loopholes to avoid FDA oversight:

This suggests one of two possibilities: either Theranos’ customers received test results generated by equipment that no federal official checked for accuracy, or Theranos wasn’t using the proprietary technology behind its $9 billion valuation to return results to patients. A recent report from The Wall Street Journal pointed toward an extreme version of option number one: that Theranos actively hid its proprietary technology from lab inspectors, which would explain why the inventions were never checked. And Theranos has publicly proclaimed it used its technology on patients, which means either that the company’s lying or patients received tests that had not been validated by any federal authorities.

“CMS did not inspect the Theranos proprietary technology.”Theranos first came under scrutiny after a report in the Journal in October, which said that Theranos’ inventions were only used on a small number of tests sold to patients. On Sunday, the paper reported that during an inspection by Centers for Medicare and Medicaid Services auditors, employees who worked in the “Normandy” section of the Theranos lab were told not to enter or exit the lab; the inspectors toured the section of the lab that housed traditional lab instruments Theranos bought from other companies but never saw the Edison machines — Theranos’ highly publicized blood analyzers. This account fits with lab inspection documents that The Verge obtained from CMS, which do not mention Theranos’ proprietary technology at all. There’s a reason for that: “CMS did not inspect the Theranos proprietary technology,” a spokesperson for CMS told The Verge in an email. Consequently, at no point between Theranos opening its first wellness center in 2013 and a surprise inspection by the FDA in August did any federal official examine the company’s proprietary technology — either its Edison machine, which reads samples, or its “Nanotainer” device, which stores blood from pinprick testing.

The lack of inspection was possible in part because Theranos registered its technology in categories that have minimal oversight. Theranos sold its tests under a designation that even the US Food and Drug Administration calls a regulatory loophole: the “lab-developed test.” Under this designation, no pre-market FDA approval is required for the company’s blood tests — as it typically is for most drugs and devices. The category was meant for research hospitals, which sometimes adapt commercial tests to suit patients’ needs, and Theranos is one of several companies using the loophole to sell its tests to the public. Instead of the FDA, regulation of Theranos’ labs fell to the Centers for Medicare and Medicaid Services.

Theranos also registered its blood containers as FDA Class I medical devices in 2013, according to the FDA. That category of medical device doesn’t require an FDA inspection. No FDA inspectors entered a Theranos facility until August of this year, during a round of surprise inspections. In the FDA’s inspection report, it referred to Theranos’ Nanotainer as an “uncleared medical device” and altered its registration to a Class II medical device, which requires greater oversight.

CMS declined to provide us with additional information about Theranos. The FDA provided some information about Theranos’ regulatory status — including the fact that Theranos registered its containers as Class I in 2013 — but declined to reveal anything further about the company.

I’m beginning to think that the whole startup culture is a code word for some sort of charity for overpriviliged white boys.

Is anyone surprised that 80% of Chicago PD dash cams don’t work properly:

On the night Laquan McDonald was shot 16 times by a Chicago Police officer, at least three dashboard video cameras in squad cars at the scene didn’t work. And the ones that did capture video did not record audio.

The massive failure was no statistical quirk.

In fact, 80 percent of the Chicago Police Department’s 850 dashcam video systems don’t record audio due to “to operator error or in some cases intentional destruction” by officers, according to a review by the Police Department.

Additionally, about 12 percent of dashcams experience “video issues” on any given day due to “equipment or operator error,” police spokesman Anthony Guglielmi said.

The Laquan shooting, which led to murder charges, has now been seen by the world — but not heard. And not every potential camera angle exists.

A sergeant on the scene reported he was unable to collect video footage from three squad cars at the scene due to system malfunctions including “disc error,” “power issue” and an “application error,” police reports show.

I gotta assume that, “operator error or in some cases intentional destruction.”

It fits with the whole “Thin Blue Line” siege mentality that permeates police forces throughout the United States.

I’m beginning to think that all these cams should be run exclusively by civilian review boards.

SpaceX has finally managed to safely land a first stage on their booster:

SpaceX engineers and on-board software maneuvered the first stage of a Falcon 9 launch vehicle back to a steady, tail-down landing at Cape Canaveral Monday, 10 min. after returning the kerosene-fueled rocket to flight following an ascent explosion on a mission to the International Space Station in June.

Success in recovering the stage, after two unsuccessful attempts to land on a barge in the Atlantic, marks a major step toward the long-sought dream of reusable commercial space launchers. While Blue Origin brought its liquid-hydrogen/liquid oxygen New Shepard vehicle back from a suborbital launch to space on Nov. 23, Monday’s SpaceX recovery was the first known landing for an unmanned orbital launcher.

Silicon Valley venture capitalist Steve Jurvetson, an early SpaceX backer, tweeted “Congrats @SpaceX for landing the rocket back on land!!!! Incredible!!! One giant leap!”

The landing at a surplus launch pad on Cape Canaveral AFS, Florida, came in the middle of three significant milestones for commercial spaceflight. For SpaceX, it marked a return to flight for the Falcon 9 launch vehicle that is the linchpin of the company’s business in the near term. For its customer, Orbcomm, it completed launching of a 17-spacecraft low Earth orbit (LEO) constellation of second-generation Machine-to-Machine “OG2” satellites.

Although only a secondary test objective on the Orbcomm-2 mission, landing the Falcon 9 stage at Launch Complex 13 on Cape Canaveral — a surplus Atlas launch site designed “Landing Complex 1” by SpaceX — was a major achievement for the Hawthorne, California-based company.

I am dubious as to the ultimate significance of the reusable stage.

At least some of the potential savings is eaten up by the additional fuel that needs to be carried to fly home, as are any arrangements for a landing site, with its associated blockhouse and firefighting equipment.

We’ll see.

Do you know how GPS works?

Basically, the satellites broadcast the time using very accurate clocks, and the differences in times received from various satellites in different positions allow a receiver to determine its positions.

Well, it looks like someone is on the cusp of using a natural clock to do the same thing, using pulsars: (paid subscription required)

Celestial navigation was a mainstay in the early days of aviation, and astronavigation is still used in nuclear bombers to overcome jamming. Now a European research project has shown the feasibility of employing pulsars for aircraft navigation that is independent of ground- or space-based equipment.

The PulsarPlane project is investigating the use of pulsar signals for real-time navigation and timing, to overcome the vulnerabilities of global navigation satellite systems and reduce operating costs for aviation in the second half of this century.

Begun in 2013 and funded by the European Union’s Framework 7 research program, the project is coordinated by the Dutch aerospace laboratory NLR and involves universities in the Netherlands, Finland, Portugal and Bulgaria.

Pulsars are fast-rotating neutron stars that emit stable, fast electromagnetic pulses with unique periods between 1.4 millisec and 5 sec. and unique shapes. Pulsars are visible from everywhere on Earth and across a wide band of frequencies.

This is insanely cook cool.

This S%$ Keeps Popping Up
I keep hearing about a super Russian jammer that blocks all NATO Sensors at 600 km.

The reports are crap.

First the claims are literally incredible, by which I mean that they are impossible to believe.

They are supposed to hit all radars, sonars, electro-optical sensors, and navigation systems: (in Comic Sans font, no less)

From the combat zone in northern Syria comes news of the deployment of a new Russian electronic jamming system which can reportedly blind radar, disrupt electronic guidance systems, and interfere with satellite imagery as well. As a result, NATO is effectively blinded inside a bubble of 600 km in diameter centered on the Russian base at Latakia, reports, Thierry Meyssan from Damascus.

The technology in question seems similar to the KRET Richag-AV system, although it apparently functions on a larger scale. A tactical version of this system was presented to journalists in the Russian city of Back in April 2015. As Sputnik reported then:

“The Richag-AV system, mounted on the Mi-8MTPR1 (a variant of the Mi-8MTB5-1 helicopter) is said to have no global equivalent. Its electronic countermeasures system is designed to jam radar, sonar and other detection systems in the aims of defending aircraft, helicopters, drones, ground and naval forces against air-to-air and surface-to-air defense systems within a radius of several hundred kilometers. It can be mounted on units from any branch of the armed forces, including helicopters and airplanes, as well as ground and ship-based forces. The Mi8-MTPR1-based Richag-AV platform, using multi-beam antenna arrays with DRFM technology, is designed to actively jam and thus ‘blind’ radar systems in order to defend against radio-electronic guided weapons systems. In a combat situation, the system would operate as part of an aviation shock attack group aimed at breaking through virtually any defense system, blinding everything up to and including the US MIM-104 ‘Patriot’ anti-aircraft missile system.” (OSNET DAILY)

Even a cursory examaminatin reveals this to be patently false.

The physics shows that it cannot work.

First, of course, is the curvature of the earth:  at 600 km, you can operate at significant altitude while the signal ia attenuated by rock and dirt.

Signal power decreases as the square of the distance, so if you are using brute force jamming, you would need to 100 times more power if the jammer were at a full distance and the sensor was at a distance of 60 km.

In terms of jamming communications, modern military communications signal hop, so any jammer would have to determine the frequency and respond.

Assuming that the jammer could instantly shift frequencies, it would be 4 milliseconds before it could jam a new frequency because of the speed of light.

With 10 frequency changes per second, and a base speed of 56 kbps for nostaligia’s sake, you end up with 2 kbps, which would have been stunning to me when I was using a 300 baud modem in the early 1980s.

Realistically, you could get more than 10x that out of any communications system, because the base rate would be higher, and the jammer could not respond instantly.

Not enough speed for full time video, but enough for video stills.

Finally, you also have created a huge beacon that would just says to a potential enemy, “Shoot me now.”

The whole idea reads like the Cylon cyberattack in the Battlestar Galactica reboot.

I just got to the bottom of this, with help from an Aviation Week article from over a month ago by the indispensable Bill Sweetman.
The system is far more limited, and does not hit things like satellites and sonar. It jams AWACS, which is eminently doable, and tactically significant:

Russian defense electronics conglomerate Kret (Concern Radio-Electronic Technology) introduced a range of new electronic warfare (EW) systems at the 2015 MAKS air show at Zhukovsky, near Moscow, including a new helicopter-borne jamming system and a high-power ground-based system designed to blind the widely used Boeing E-3 Airborne Warning & Control System (AWACS) and other systems using the S-band (2-3 GHz). According to Kret, the Krasukha-2 AWACS jammer can act as a high-power microwave weapon, with enough power to damage target hardware. It is developed by Kret’s Gradient subsidiary and is mounted on a BAZ 6909 8 X 8 truck.

The 9-ft.-dia. parabolic reflector focuses energy from a battery of feed horns and at least two secondary side feeds, and sits, with the radio-frequency signal generators, on a 360-deg.-rotatable platform, with up to 5 deg. elevation. It is claimed to be effective over a 45-deg. angle to the main radar beam, jamming through the radar’s sidelobes, and able to mask a target from an AWACS that is 150-300 km (93-186-mi.) from the jammer. The 100-kW-plus generator and power-conditioning system is built into the truck chassis and is driven by a spur from the transmission.

It is an impressive piece of kit, but it does not violate the laws of physics as claimed in the other article.

If they manage to integrate this with an electronically scanned antenna, it would be even more formidable, but it isn’t a world beater.

It is notable in that it is a capability that NATO does not possess, our doctrine is predicated on a system where we always have air superiority.

Russian doctrine does not operate under this assumption.

Blow Up One Mainframe, and Shut Down the Entire F-35 Fleet

No Comments

The US military, and Lockheed-Martin have structured the software of the F-35 so that the plane cannot fly without a direct connection to a L-M mainframe:

The unilateral decision by the United States to locate all F-35 software laboratories on its territory, and to manage the operation and sustainment of the global F-35 fleet from its territory, has introduced vulnerabilities that are only beginning to emerge.

The biggest risk is that, since the F-35 cannot operate effectively without permanent data exchanges with its software labs and logistic support computers in the United States, any disruption in the two-way flow of information would compromise its effectiveness.

All F-35 aircraft operating across the world will have to update their mission data files and their Autonomic Logistic Information System (ALIS) profiles before and after every sortie, to ensure that on-board systems are programmed with the latest available operational data and that ALIS is kept permanently informed of each aircraft’s technical status and maintenance requirements. ALIS can, and has, prevented aircraft taking off because of an incomplete data file.

Given that the United States hopes to sell hundreds of F-35s to allies in Europe, Asia and Australia, the volume of data that must travel to and from the United States is gigantic, and any disruption in Internet traffic could cripple air forces as the F-35 cannot operate unless it is logged into, and cleared by, ALIS.

For example, “Mission data load development and testing is a critical path to combat capability,” Pentagon OT&E director Michael Gilmore said in his fiscal 2014 report. “Accuracy of threat identification and location depend on how well the mission data loads are optimized to perform in ambiguous operational environments.”

Updating and uploading mission data loads depends on a functioning Internet, and as Wired.com noted in an Oct. 29 story, “undersea Internet cables are surprisingly vulnerable.” It quoted Nicole Starosielski, a media scholar at New York University, as saying that “people would be surprised to know that there are a little over 200 systems that carry all of the internet traffic across the ocean, and these are by and large concentrated in very few areas. The cables end up getting funneled through these narrow pressure points all around the globe.”

………

The fear is that an “ultimate Russian hack on the United States could involve severing the fiber-optic cables at some of their hardest-to-access locations to halt the instant communications on which the West’s governments, economies and citizens have grown dependent,” the article said.

Whatever the other repercussions, such an event would severely limit the ability of the world’s F-35 fighters to fly – due to a loss of ALIS link – and to operate effectively, as their fighting ability would disappear if their software and mission data files could not be updated.

………

Given that the ALIS mainframe is located at Fort Worth, Texas, operating the F-35 will require three very large data conduits to and from these locations, again using Internet cables as the volume of data is too great for satellite transmission.

In fact, if the F-35 performs as advertised, it should gather very argue amounts of tactical data during each mission – data that it will have to transmit to the software labs in the US so they can be used to update the mission data files, adding another large volume data flow in both directions.

They don’t need to cut internet cables.  They send some guy in with an explosives vest to the mainframe, and the fleet is grounded.

More important to our foreign “Partners” is that this also means that an F-35 fleet can shut down by Lockheed-Martin over a  billing or maintenance dispute, or by the US over a foreign policy dispute.

This is not a bug, this is a feature, and it is one that almost certainly came from L-M, because it creates a captive customer:  No one can maintain the aircraft without paying a toll to them.

Even if the aircraft performs as promised, the basic concept for its operation is untenable.

Run away from this clusterf%$#.

Well, Someone in the Pentagon Can Think beyond Dick Swinging

The Russians and the US are developing communication protocols in Syria.

I am not talking about some sort of foreign relations touchy feeley crap.  I am talking about about the actual technical protocols to allow Russian and US forces to communicate with each other:

US and Russian fighter pilots communicated directly in the skies over Syria on Tuesday in a successful test of new procedures for avoiding incidents as they pursue separate air campaigns, the Pentagon said.

Navy Capt. Jeff Davis said the test, carried out between one aircraft from each side over south central Syria, lasted three minutes and “met its intended objective.”

“This test assured that the first time this mode of communication was used would not be during an unplanned encounter,” Davis said.

The United States and Russia signed a “memorandum of understanding” on Oct. 20 aimed at de-conflicting their air operations over Syria, where they are waging parallel air campaigns with different objectives.

………

A US defense official said Tuesday’s test did not amount to joint training with the Russians, as Moscow has described it in a statement.

“We put on hold all military to military cooperation following the onset of Russian aggression in Crimea, and that remains in effect,” the official said, speaking on condition of anonymity.

Actually, what this means is that someone in the US military has realized best case scenario with all of this is that we don’t have US and Russian forces shooting at each other.

When one considers the facts on the ground:

  • The US is bombing ISIS and supporting al Qaeda affiliated fighters it has labeled “moderates” seeking to overthrow Assad, while supporting the Kurd’s fight against Isis.
  • The Turks bombing the Kurds and supporting both Isis and Al Qaeda affiliated fighters seeking to overthrow Assad.
  • The Saudis supporting both Isis and Al Qaeda affiliated fighters seeking to overthrow Assad.
  • The Russians coordinating airstrikes with the Assad regime against both ISIS the al Qaeda affiliated fighters seeking to overthrow Assad.

It’s a wonder that they haven’t already started shooting at each other, what with all the all the bullets flying in different directions.

Tehran Deployes MARV Reentry Vehicls

Pershing and EMAD Comparison
    Pershing II MARVEMAD


    MARV flight profile Indian Agni 2        

Iran has a new ballistic missile, the EMAD, and it appears that it will deploy a maneuverable reentry vehicle (MARV), which could potentially result in much higher accuracy and the possible ability to evade defenses:

Iran has successfully test fired a new, domestically produced, medium range ballistic missile, named Emad (pillar, in Farsi). “This is Iran’s first medium range missile that can be guided and controlled until hitting the target,” Iran’s Defense Minister Hossein Dehghan was quoted as saying. According to analyst estimates the new missile could be ready for service next year.

 The Islamic Republic of Iran already has surface-to-surface missiles with ranges of up to 2,000 kilometers that can hit Israel and US military bases in the region. The new missile seems to be a derivative of these liquid-propelled Ghadr and Shahab missiles. This Medium-Range Ballistic Missile (MRBM) is also powered by liquid-fuel and; according to unconfirmed sources, it has a range of up to 1,700 km., (1,060 miles) carrying a payload of 750 kg (1,650 pounds). Its accuracy is estimated at 500 meters (1,650 ft), compared of 2,000 meters (1.2 miles) accuracy achieved by the current Shahab 3 missile.

Given that this saw deployment with the US in the late 1970s, and is currently being deployed by India, this is not, as this article implies, some sort of exotic super technology.

Instead, it is a rather mature technology, and as such, is doubtless accounted for in the software of most ABM systems.

One thing that I did notice, at least compared to the Pershing II and Agni II is that the control surfaces are much smaller, which would imply that it would produce smaller deviations from a ballistic flight path.

I think that this implies that its primary function is to increase accuracy of the missile, and not to evade interceptors like THAAD and Arrow, as terminal guidance would necessarily involve less control authority.

Given the range, 1700 km, the top speed would be in the 3.5 km/s range, which means that temperature of the nose cone might be low enough to allow for a terminal radar to improve accuracy, much as the Pershing II did.  (Wiki lists the Pershing II CEP of 30m)

If the CEP could be kept to under 100m, this would greatly increase its utility when carrying a conventional warhead.

What a Stupid F%$#ing Idea

No Comments

If I had a time machine, I would go back in time to find the father of whoever came up with the idea of adding copy protections to JPEG images, and kick that man in the nuts so hard that he would be rendered sterile:

So much for hopes that the tech industry would back away from copyright protection any time soon. The Joint Photographic Experts Group recently launched a Privacy & Security initiative that potentially brings digital rights management (DRM) to regular JPEG images, not just the specialized JPEG 2000 format. The proposal could protect your privacy by encrypting metadata (such as where you took a photo), but it could also prevent you from copying or opening some pictures. Needless to say, that opens up a can of worms when it comes to fair use rights. If someone slapped DRM on a photo, you couldn’t use it for news, research or remixed art — many of the internet memes you know wouldn’t be possible.

This is so unbelievably stupid.

I Did Not Think that You Could Use Roller Bearings for This

No Comments

There are a number of reasons why roller bearings (ball bearings, cylindrical roller bearings, spherical roller bearings, tapered roller bearings, etc.) find use.

They provide a low drag solution, and, particularly for low speed applications, like turret rings, they tend to be the favored solution.

For higher speed applications, things like crankshaft bearings and bearings though, they are not used, because they tend to shake themselves to pieces.

Instead, fluid bearings are used, where the bearing moves with respect to the journal supported on a thin film of a fluid, typically some sort of oil or air. (Think air-hockey puck)

There is more drag in the system, but it functions at much higher speeds.

This is why you do not see roller bearings in jet enginse, at least that was why until now: (paid subscription required)

A recent development in Germany by FAG Aerospace and MTU Aero Engines could affect turbofan engine operations in three key areas: oil consumption, fuel economy and power generation.

The companies designed a main-shaft ball bearing that exceeds, reportedly for the first time, an operational speed parameter of 4 million mm/min. (160,000 in./min.)—66% greater than the 2.4 million mm/min. generated by most conventional bearings during takeoff.

At maximum speed, the bearing reportedly consumes the same amount of oil and generates identical temperatures as conventional bearings. At normal speed up to 50% less oil—6 liters/min. (1.6 gal./min.)—is needed for cooling, temperature is 25C (77F) lower and power loss drops as much as 25%.

Peter Glockner, head of product design at FAG Aerospace, attributes the reduction in oil consumption to, among other features, outer-ring cooling technology and an “integrated squeeze-film damper” that mitigates vibration load. The benefits of lower oil consumption and reduced vibration include power-loss savings, which “increase[s] the mechanical efficiency of the engine” and thus lowers fuel consumption, he adds.

The fuel savings are low: FAG Aerospace estimates the technology could save 200,000 tons of fuel annually for global turbofan fleets. In 2015, total fuel consumption for all aircraft is forecast to be up to 230 million metric tons.

Nevertheless, the technology appears to have clear engine-power advantages, and even minuscule savings add up for large operators, including the military.

Assumign that the price comes down, I would expect to see this in automotive turbocharger bearings, and (eventually) main engine bearings.

When I was in E-school, this was the sort of application for roller bearings that we were basically told, “Don’t even think about it”.

And now someone is trying to sell it.

I am impressed
