The U.S. Air Force Safety Center confirmed that the Automatic Ground Collision Avoidance System (Auto GCAS), developed by Lockheed Martin, NASA, and the U.S. Air Force Research Laboratory, saved the life of an F-22 pilot flying in Alaska in June 2020. The pilot was operating the jet in Instrument Meteorological Conditions and experienced spatial disorientation. When the F-22 was at an altitude of 13,520 feet above sea level and traveling about 600 mph with its nose pointed downwards, the onboard Auto GCAS software initiated an automatic fly-up, steering the plane out of its rapid descent. The system finished the recovery process when the aircraft was about 2,600 feet above ground.
The problem might not be fixed until August of this year.
Yup—my 2007 Honda Accord forgot to change to DST this year and I can't set clock to correct time. Planned obsolescence; they surely figure people will replace cars when clock is wrong.
“Researchers at Google, National University of Singapore, Yale-NUS College, and Oregon State University have recently carried out a study evaluating the risks of these type of attacks, which essentially entail ‘poisoning’ machine learning models to reconstruct the sensitive information hidden within their parameters or predictions. Their paper, pre-published on arXiv, highlights the alarming nature of these attacks and their ability to bypass existing cryptographic privacy tools.”

A circuit board's power consumption can reveal malicious tampering designed to facilitate Trojan attacks to steal sensitive data or crash a device when triggered. Huifeng Zhu and colleagues at Washington University created the PDNPulse test to analyze a printed circuit board's power consumption in order to identify tampering by comparing it to a device known to be secure. PDNPulse looks for small variations in such a so-called “fingerprint” of power consumption, based on measurement at several points. Using the test, the researchers were able to detect Trojan modifications on various circuit boards with perfect accuracy. While no firm evidence has been found to prove a circuit board-based Trojan attack has actually happened, Theodore Markettos at the UK's University of Cambridge said he believes in the concept's feasibility.

Momentum and capital are building for startups developing chips that process data via light rather than wires. Ayar Labs, which is developing silicon photonics technology that harnesses photons in chips, said it had raised $130 million from investors, including chip behemoth Nvidia. Other startups using silicon photonics to construct quantum computers, supercomputers, and chips for driverless vehicles also are attracting major investment. “What the Ayar Labs guys do so well…is they solved the data interconnect problem for traditional high-performance [computing],” said Peter Barrett at venture capital firm Playground Global. “But it's going to be a while before we have pure digital photonic compute for non-quantum systems.”
Amazon Fresh—BEWARE “Just Walk Out” Went on Tuesday to check out the new Amazon Fresh store in Fairfax and try out their “Just Walk Out”. It is a complete failure. It charged us for two packages of expensive steaks that we picked up to look at and then put back. It also charged us for a box of strawberries that we didn't touch and didn't catch a jar of olives that we did get. Then expected a receipt emailed to us by the time we walked to our car. Instead we didn't get an actual receipt until five hours later. So you have no way to verify before you leave the parking lot that you got charged accurately. Fortunately we got through on the phone to a very helpful customer service person (800-250-0688) and got the incorrect charges reversed. But why go through this hassle. If you try this new store just go through the normal checkout line! 10440-10450 Fairfax Boulevard, Fairfax VA
CNN+ is giving a full refund to original payment methods by May 28. HOWEVER, Gmail appears to be sending the email explaining this to Spam in many (or all) cases.
“Price-setting algorithms play a major role in today's economy. But some experts worry that, without careful checks, these programs might inadvertently learn to discriminate against minority groups and possibly collude to artificially inflate prices. Now a new study suggests that an economic tool dating back to ancient Rome could help curb this very modern concern.”
Pricing models can exploit big datasets to personalize consumer prices for goods and services. But price controls that include a “willingness to pay” parameter can mitigate predatory algorithms.

The Willpower to reduce crypto[currency]'s carbon footprint is muted.
Pressure on Bitcoin to switch from proof of work to proof of stake (which requires much less power) is coming from several directions. The difference between the two is like the difference in height between the world's tallest building and a single screw. … For bitcoin to change direction would require “almost like a constitutional convention of sorts. Inertia usually wins.” (Ryan Selkis, co-founder of Messari)
This is the last interview that the late Carl Sagan had with Charlie Rose, on May 27, 1996. The seek position I have selected is specifically where he speaks on the dangers of political control of technology, which (as usual for him) is incredibly prescient. But the entire interview is strongly recommended. He was one of the greatest minds in my lifetime. -L

Breaking Twitter is easy: If you restore toxic content, you drive away advertisers. If you move to a subscription model—even without toxic content but especially with—you won't get enough subscribers to be self-sustaining. Result: No more Twitter—which may be the plan.
Gwyneth Paltrow, Mila Kunis and other celebs are pushing women to invest in NFTs, which some see a revival of self-serving feminism.
Gwyneth Paltrow and Mila Kunis joined a Zoom in January to encourage 5,000 women in the audience to break into the male-dominated world of crypto.
“We have watched a lot of these bros get together and earn a lot of money.” said Paltrow, sporting a black turtleneck, sun-kissed glow and a disarming smile. “We deserve to be in this space just as much.”
Kunis had recently launched a cartoon series with her husband, Ashton Kutcher, that uses NFTs, a digital deed often used to sell digital art that exploded into a $25 billion market. “We are so conditioned as women to be risk-averse, “ Kunis said. “I want to take risks and what happens.” […]
Like the girlboss, these NFT brands mix hustle culture with the language of social justice, blurring the line between community and commerce, and dangling empowerment as a customer acquisition strategy.
Randi Zuckerberg, the older sister of Meta's chief executive, told the BFF crowd that six months ago, she was just like them.
“I was skeptical, I was confused. Fast-forward to now, I now own more than 100 NFTs!”, Zuckerberg said, comparing NFTs of digital art to collecting designer handbags. […]
The BFF Zoom event from January promised to answer whether NFTs were all a scam. But there was little discussion about volatility.
A few minutes into the Zoom conference, Morin pointed to an NFT collection that sold for $69 million at Christie's, telling the crowd, most of whom reported having little knowledge of the industry. “This is the type of wealth that's possible for people that are participating in this new ecosystem.”
[Funny, I never told my financial advisor I wanted to “take risks, see what happens”.]

The Internet has been revolutionary. It provides unprecedented opportunities for people around the world to connect and to express themselves, and continues to transform the global economy, enabling economic opportunities for billions of people. Yet it has also created serious policy challenges. Globally, we are witnessing a trend of rising digital authoritarianism where some states act to repress freedom of expression, censor independent news sites, interfere with elections, promote disinformation, and deny their citizens other human rights. At the same time, millions of people still face barriers to access and cybersecurity risks and threats undermine the trust and reliability of networks.

Very late yesterday, I got an email from my little brother, informing me that he, and his wife, tested positive for CoVID. I last saw my little brother fourteen days ago. I don't have any of the common signs or symptoms of CoVID. No cough, no fever, and I still smell and taste things just fine. I have not been tested: these days I have no idea if I even qualify to get tested. I assume I am on the extreme outside edge of the possibility of infection or contagion, and I'm not even sure if “14 days” is still the recommended quarantine time.
As blind, random chance, and my generally non-existent social life, would have it, yesterday I had grief group, a monthly lunch group, and an informal, bi-weekly coffee time with the tenants here. Today I have Old Guys Coffee Morning and a Bible study at my emergency backup church. (I have already sent a warning, and a query as to whether they [both groups] want me to stay away.) I have warned the groups I was with yesterday. I have sent a query to the pharmacy as to whether I yet qualify for “rapid” CoVID tests. (I haven't yet started to research whether there is any possibility of getting tested any other way.) I have sent a warning to a friend I had lunch with just after I saw my little brother, and Number Two Step-Daughter and Number One Grandson, with whom I had dinner a few days ago. And a warning to my main church, where I served coffee at Easter service just after I last saw my little brother, and subsequently taught a Sunday School class for the whole Sunday School …
(Yesterday I also had a practice session with BSidesVancouver, but that was over Hopin, so I doubt there was any risk, there. If I do, by some extreme chance, get CoVID, and have to miss CanSecWest, after I get better I will drive to Ontario and kill my little brother …)
> An attacker with source code will double check each strcmp for a buffer > overflow.
Considering that we're talking Bing and Cortana here, if their authors still used strcmp, leaked source code is not their biggest problem. This isn't XX century code from back when we didn't know any better, Cortana in particular was released a good decade after secure coding became the thing.
Quick look at the original article that the main concern with that hack is that the sources (may) also include code signing keys and those are much more valuable than any “C string library” calls that may or may not exist in the code.

But can they be tricked into driving through red lights? And would the logging in the driverless car show that the software thought the light was green, with resulting liability and reputational damage?
