A new article examines a study which suggested fresh asphalt is "a significant, yet overlooked, source of air pollution," (as reported by Science). "In fact, the material's contribution to one kind of particulate air pollution could rival or even exceed that of cars and trucks."

UPI reports: And its emissions double as its temperature increases from 104 to 140 degrees Fahrenheit, researchers found. Sunlight plays a key role in these asphalt emissions, with even moderate levels of sunshine tripling the release of air pollutants, according to the study published Sept. 2 in the journal Science Advances... In-use pavement usually gets as hot as between 117 and 153 degrees Fahrenheit in the summer, while roofs can reach 167 degrees, the study authors said.

As the major contributors to air pollution get cut back — for example, through cleaner vehicle emissions — passive pollution sources like these will have a growing influence on the air we breathe, said Peter DeCarlo, an associate professor and air pollution expert with Johns Hopkins University, in Baltimore. "In doing that reduction, we are discovering these new sources that are now playing a more prominent role in our air pollution issues," DeCarlo said.... Asphalt probably contributes most to air pollution when it's freshly laid, DeCarlo added. During the paving process, asphalt is heated to as much as 248 to 320 degrees Fahrenheit, the researchers said. "If you've ever been around people laying asphalt, you smell it. It's clear something is getting into the air when that happens," DeCarlo said. But asphalt likely continues to emit air pollutants even after it's aged, when sunlight bakes the material, he noted.

Switching to concrete for paving would help reduce emissions, he said, but concrete is not an ideal paving material in all locales. Another possible solution might be the application of "cool pavement" technology, where colored sealants are applied to paved surfaces so they reflect more solar energy and become less likely to heat up, Gentner said. Emissions might also vary with different asphalt application methods and different formulations of the paving product, Gentner suggested.

I've only paid for a magazine subscription once in my life — to Jack Rickard's Boardwatch magazine, which through the late 1990s was the geekiest read in town.

You can still read 70 issues of the magazine from more than 25 years ago at Archive.org. But this week the small Southeast Missourian newspaper reported that the magazine's original editor/publisher Jack Rickard has died at age 65: Following his graduation in 1973, Jack enlisted in the U.S. Navy. He proudly served aboard the USS Midway as an aviation support equipment technician. Following a distinguished tour in the Navy, Jack enjoyed a career as a technical writer in the defense industry.

Jack was a Mensa member and an early adopter of new technologies. His keen intelligence helped him to see the value of the internet as early as the 1980s. He started Boardwatch... Supported by a strong team, Jack developed Boardwatch into a successful magazine, which he sold in 1998.

Following his initial professional success, Jack proudly returned to his hometown of Cape Girardeau, Missouri. While in Cape Girardeau, Jack continued to pursue his interest in innovative technologies, including aviation and electric cars. In 2008, Jack established EVTV, an internet-based platform that taught individuals methods to convert gasoline-powered vehicles into electric-drive vehicles. As electric cars became popular, Jack expanded EVTV to focus on solar power storage.
Jack always felt like an old friend, even as his role in the tech community kept evolving. (Rickard's editorials at EVTV always featured a black-and-white sketch of the author — a tradition he'd continued through more than three decades of writing.)

Even Boardwatch "began as a publication for the online Bulletin Board Systems of the 1980s and 1990s," explains Wikipedia, "and ultimately evolved into a trade magazine for the Internet service provider (ISP) industry in the late 1990s... Boardwatch spawned an ISP industry tradeshow, ISPcon, and published a yearly Directory of Internet Service Providers. In 1998, Rickard sold a majority interest in Boardwatch and its related products to an East Coast multimedia company, which was then acquired by Penton Media in 1999 and moved to other ventures...
This week fans left testimonals on his funeral home's web site. "What an inspiration to mankind," read one. "Always enjoyed his views on any subject. We could use more people in this world with his wit and knowledge."

And another just wrote "Jack you were the most insightful speaker on the topic of electric vehicles. I enjoyed every second of your wisdom and videos and will continue to watch them for years to come. Rest In Peace my YouTube friend."

Forbes reports: Firefox is exploring subscriptions and other "value exchange" services to ease its financial dependence on rival Google, according to the browser's lead developer.

Firefox maker, Mozilla, is in the uneasy position of being financially dependent on its search deal with Google, which accounts for the majority of the organization's revenue. Although Mozilla only last month renewed the search deal, ensuring Google remains the default search engine for Firefox in the U.S. and other territories, the company is keen to explore other ways of raising revenue, including charging users for services.

Mozilla's partnership with Google is an uncomfortable alliance, not only because the companies distribute rival browsers, but because their values are markedly different. While Google generates the vast bulk of its revenue from online advertising, Firefox's developers expend much of their effort creating tools that thwart advertisers, including the automatic blocking of third-party tracking tools and social-media trackers. "At Mozilla, we tend to believe things are at their best when users have this transparent value exchange," said Dave Camp, senior vice president of Firefox at Mozilla. "The advertising model has become a default way to fund things on the internet and to fund products, and we're pretty interested — not just for financial reasons, but actually for health of the internet reasons — to explore how can we do better for users than advertising."

Mozilla recently began charging users $4.99 per month for its VPN product and Camp says the company is exploring other subscription products. "We don't have any immediate plans in the Firefox team to do add-on services or anything like that at the moment, but we're going to look at other ways to get some value exchange going on," said Camp.

An anonymous reader shares a fascinating true-crime story from Pittsburgh. Smithsonian magazine reports: Like nuclear power plants and sensitive computer networks, the safest rare book collections are protected by what is known as "defense in depth" — a series of small, overlapping measures designed to thwart a thief who might be able to overcome a single deterrent. The Oliver Room, home to the Carnegie Library of Pittsburgh's rare books and archives, was something close to the platonic ideal of this concept. Greg Priore, manager of the room starting in 1992, designed it that way.

The room has a single point of entry, and only a few people had keys to it. When anyone, employee or patron, entered the collection, Priore wanted to know. The room had limited daytime hours, and all guests were required to sign in and leave personal items, like jackets and bags, in a locker outside. Activity in the room was under constant camera surveillance. In addition, the Oliver Room had Priore himself. His desk sat at a spot that commanded the room and the table where patrons worked. When a patron returned a book, he checked that it was still intact. Security for special collections simply does not get much better than that of the Oliver Room.

In the spring of 2017, then, the library's administration was surprised to find out that many of the room's holdings were gone. It wasn't just that a few items were missing. It was the most extensive theft from an American library in at least a century, the value of the stolen objects estimated to be $8 million...
Perpetrating a daring 25-year heist, the thief "stole nearly everything of significant monetary value," the magazine reports. So who done it? Just about the only thing that keeps an insider from stealing from special collections is conscience. Security measures may thwart outside thieves, but if someone wants to steal from the collection he stewards, there is little to stop him. Getting books and maps and lithographs out the door is not much harder than simply taking them from the shelves...
The perpetrator was ultimately sentenced to three years' house arrest and 12 years' probation, the article reports, while his fence received four years' house arrest and 12 years' probation.

"After the sentences were made public, Carole Kamin, a member of the board of the Carnegie Natural History Museum, wrote to the Pittsburgh Post-Gazette that supporters of local nonprofits 'were appalled at the unbelievably light sentences.'"

ZDNet reports: An anonymous reader shares this enthusiastic report from ZDNet: Earlier this year, Linus Torvalds approved of adding drivers and other components in Rust to Linux.* Last week, at the virtual Linux Plumbers Conference, developers gave serious thought to using the Rust language for new Linux inline code. ["Nothing firm has been determined yet," reported Phoronix, "but it's a topic that is still being discussed."] And, now Amazon Web Services (AWS) has announced that its just-released Bottlerocket Linux for containers is largely written in Rust.

Mozilla may have cut back on Rust's funding, but with Linux embracing Rust, after almost 30-years of nothing but C, Rust's future is assured. Rust was chosen because it lends itself more easily to writing secure software. Samartha Chandrashekar, an AWS Product Manager, said it "helps ensure thread safety and prevent memory-related errors, such as buffer overflows that can lead to security vulnerabilities." Many other developers agree with Chandrashekar.

Bottlerocket also improved its security by using Device-mapper's verity target. This is a Linux kernel feature that provides integrity checking to help prevent attackers from overwriting core system software or other rootkit type attacks. It also includes the extended Berkeley Packet Filter (eBPF), In Linux, eBPF is used for safe and efficient kernel function monitoring.
* Linus's exact words were "people are actively looking at, especially doing drivers and things that are not very central to the kernel itself, and having interfaces to do those, for example, in Rust. People have been looking at that for years now. I'm convinced it's going to happen one day."

The article also reminds readers that AWS's Bottlerocket "is also designed to be quick and easy to maintain... by including the bare essentials needed to run containers..."

"Besides its standard open-source elements, such as the Linux kernel and containerd container runtime, Bottlerocket's own code is licensed under your choice of either the Apache 2.0 or the MIT license."

An anonymous reader quotes a report from CNBC: Japan's SoftBank was reportedly the "Nasdaq whale," that bought billions of dollars in individual stock options in big tech companies over the past month, driving up volumes and contributing to a trading frenzy. Softbank declined comment on a Financial Times story that quoted unnamed sources who said it was buying equity derivatives on a massive scale. Rumors had circulated in the market that there were large players behind the frenzied activity in the options market for big tech and internet stocks, and SoftBank was one named mentioned in connection with extreme volumes in some out-of-the-money calls.

According to the Wall Street Journal, SoftBank had made regulatory filings showing it bought nearly $4 billion in shares of Amazon, Microsoft, and Netflix, plus a stake in Tesla. The paper quoted a source saying that SoftBank spent roughly $4 billion buying call options tied to its stock holdings, but also in other names. It then could profit from the run up in stocks and subsequently unload its position to other parties. SoftBank was trading in names that are among the key drivers of the stock market. Apple, Amazon , Microsoft, Facebook and Google equal about a quarter of the S&P 500, and they have been drivers of a big chunk of its gains. One options trader explained that those names can be proxies for the market, and can be hedged against the S&P 500 and vice versa. The options market activity was credited by analysts for adding froth to the stock market itself. Some of that is now reversing.

An anonymous reader quotes a report from The Verge: Today, the Trump administration released its fifth Space Policy Directive, this one designed to come up with a list of best practices for the space industry on how to protect their spacecraft from cyber threats. The goal is to encourage the government and space industry to create their space vehicles with cybersecurity plans in place, incorporating tools like encryption software and other protections when designing, building, and operating their vehicles. [...] To combat these threats, Space Policy Directive 5 lays out guidelines that companies should try to adhere to as they launch satellites and other vehicles to space. The administration is recommending operators use various types of software to ensure that the data they receive from their spacecraft is encrypted. The directive also encourages companies to use trusted supply chains and oversee the safety of their ground systems -- the facilities they use to send signals and retrieve data from their spacecraft. The report also recommends protecting against jamming and spoofing of satellites. "Sometimes the jamming can be fairly crude; other cases, some of the spoofing can be fairly sophisticated if somebody's trying to get on board," one official said. "So there's a whole range of things that you need to look at kind of end-to-end."

Ultimately, the directive says that government agencies should work with commercial companies to further refine what these best cybersecurity practices should be, especially since many in the space industry already implement these strategies when building and launching vehicles. [...] SPD-5 is the latest policy directive from the Trump administration designed to shape the U.S. space agenda. Trump's first directive instructed NASA to send humans back to the Moon, while other directives have focused on coming up with a way to oversee space traffic and streamlining regulations for space licenses.

An anonymous reader quotes a report from CNBC: The Pentagon said Friday it will stick with Microsoft for a major cloud contract that has been disputed in court for months. The JEDI, or Joint Enterprise Defense Infrastructure, deal has become one of the most hotly contested contracts for the Department of Defense. The contract is intended to modernize the Pentagon's colossal IT infrastructure and could be valued up to $10 billion for services rendered over as many as 10 years.

"The Department has completed its comprehensive re-evaluation of the JEDI Cloud proposals and determined that Microsoft's proposal continues to represent the best value to the Government," the Pentagon said in a statement. "The JEDI Cloud contract is a firm-fixed-price, indefinite-delivery/indefinite-quantity contract that will make a full range of cloud computing services available to the DoD. While contract performance will not begin immediately due to the Preliminary Injunction Order issued by the Court of Federal Claims on February 13, 2020, DoD is eager to begin delivering this capability to our men and women in uniform." The outcome represents a loss for Amazon, which challenge the award of the contract after the Pentagon gave it to Microsoft in October. An Amazon representative did not immediately respond to request for comment. "We appreciate that after careful review, the DoD confirmed that we offered the right technology and the best value. We're ready to get to work and make sure that those who serve our country have access to this much needed technology," a Microsoft spokesperson told CNBC in an email.

As schools start around the US, many face a problem with getting all their students connected for virtual classes. To help with that crisis, T-Mobile has launched its grant program that aims to eliminate the so-called homework gap. From a report: Unveiled a year ago, Project 10Million will provide hotspots and free connectivity for millions of students around the country. Now that T-Mobile and Sprint have merged, the combined company has hammered out the project's specifics and is opening it up to schools on Thursday. It has allocated $10.7 billion over the life of the 10-year program, up from the initial $10 billion pledge in late 2019.

"Our mission is to not stop until we've provided the connectivity and devices for students to be connected who can't afford to be connected, so that they can do their homework," T-Mobile Chief Marketing Officer Matt Staneff said in an interview ahead of the news. "We believe we can make a difference, and we're taking this on at scale." Students who are part of the national free- and reduced-price lunch program for low-income families will qualify for Project 10Million. A school district applies for the grant and is able to specify the needs of its students. It doesn't share personal, identifying data with T-Mobile, aside from a ZIP code at times to be sure students have steady T-Mobile service where they live. The schools handle the distribution of the hotspots and can tap into dedicated T-Mobile support for setting up the device or other troubleshooting.

The Federal Communications Commission on Friday said it could cost an estimated $1.8 billion to remove and replace Huawei and ZTE equipment that's in US telecommunications networks receiving federal funds. From a report: In June, the FCC officially classified Huawei and ZTE as national security threats, though since 2019, the agency has barred carriers from using its $8.3 billion a year Universal Service Fund to purchase equipment from the two Chinese tech giants. US President Donald Trump also signed legislation in March that stops carriers from using government funds to buy network equipment from Huawei and ZTE. "By identifying the presence of insecure equipment and services in our networks, we can now work to ensure that these networks -- especially those of small and rural carriers -- rely on infrastructure from trusted vendors," said FCC Chairman Ajit Pa in a release, adding that he would "once again strongly urge" Congress to appropriate funding to reimburse carriers.

Mark Zuckerberg tells "Axios on HBO" that Facebook is imposing new election rules to deter use of the platform to spread of misinformation and even violence, and to help voters see the results as "legitimate and fair." From a report: The new measures, announced Thursday, include throwing a flag on posts by candidates who claim premature victory, and forbidding new ads within a week of Election Day. "There is, unfortunately, I think, a heightened risk of civil unrest in the period between voting and a result being called," Zuckerberg told Axios' Mike Allen. "I think we need to be doing everything that we can to reduce the chances of violence or civil unrest in the wake of this election."

Mozilla will add a new security feature to Firefox in October that will make it harder for malicious web pages to initiate automatic downloads and plant malware-laced files on a user's computer. From a report: Called a drive-by download, this type of attack has been around for two decades and usually takes place when users visit a website that contains malicious code placed there by an attacker. The role of the malicious code is to abuse legitimate features in browsers and web standards to initiate an automatic file download or download prompt, in the hopes of tricking the user into running a malicious file. There are multiple forms of drive-by downloads, depending on the browser feature attackers decide to use. Browsers like Chrome, Firefox, and Internet Explorer have, across the years, gradually deployed various forms of protections against automatic drive-by downloads, but 100% protection can't be fully achieved because browser makers can't fully block legitimate web features and also because of the shifting landscape of web attacks, with attackers always finding a new hole to poke at.

sciencehabit writes: Every year, mining and industrial activity generates billions of tons of slurries, gravel, and other wastes that have a high pH. These alkaline wastes, which sit either behind fragile dams or heaped in massive piles, present a threat to people and ecosystems. But alkaline wastes could also help the world avert climate disaster. Reacting these wastes with carbon dioxide (CO2) from the air converts gaseous carbon into minerals and neutralizes the wastes' alkalinity. Carrying this out on a global scale could trap between 310 million to 4 billion tons of CO2 annually, according to recent surveys. That could provide the world with a much needed means of lowering atmospheric CO2. But there are major hurdles. Governments will need to offer incentives for mineralization on the massive scale needed to make a dent in atmospheric carbon. And engineers will need to figure out how to harness the wastes while preventing the release of heavy metals and radioactivity locked in the material.

The Trump administration will decline to pay tens of millions of dollars owed to the World Health Organization (WHO) in annual dues as part of the U.S.'s withdrawal from the global body, which is scheduled for next year. The Hill reports: The Associated Press reported that the U.S. will not pay just over $60 million owed in 2020 dues to the organization, and Reuters reported that the decision also will affect about $19 million still owed in 2019 dues. A decision to forgo the payments comes as the Trump administration has hammered the WHO for months over supposedly bowing to China's wishes and essentially acting as a PR shop for China's government during the early stages of the pandemic while Chinese officials allegedly stymied international health experts from learning about the virus.

In a statement, a WHO spokesperson said the agency would review its options and encourage the U.S. to reverse course. "We refer you to our previous statements of regret regarding the U.S. decision to withdraw. We await further details, which we will consider carefully," the spokesperson told Reuters.
