In an interview with Axios on Tuesday, Bill Gates warned Apple and other tech giants that they risk the kind of nightmarish government intervention that once plagued his Microsoft if they act arrogantly. Axios reports: The big picture: "The companies need to be careful that they're not ... advocating things that would prevent government from being able to, under appropriate review, perform the type of functions that we've come to count on." Asked if he sees instances of that now, Gates replied: "Oh, absolutely." Why it matters: With the Big Tech companies feeling they're suddenly drawing unfair scrutiny, this is Microsoft's co-founder saying they're bringing some of the problems on themselves, by resisting legitimate oversight.

The most recent Linux Questions poll results are in. Steven J. Vaughan-Nichols, writing for ZDNet: LinuxQuestions, one of the largest internet Linux groups with 550,000 members, has just posted the results from its latest survey of desktop Linux users. In the always hotly-contested Linux desktop environment survey, the winner was the KDE Plasma Desktop. It was followed by the popular lightweight Xfce, Cinnamon, and GNOME. If you want to buy a computer with pre-installed Linux, the Linux Questions crew's favorite vendor by far was System76. Numerous other computer companies offer Linux on their PCs. These include both big names like Dell and dedicated small Linux shops such as ZaReason, Penguin Computing, and Emperor Linux. Many first choices weren't too surprising. For example, Linux users have long stayed loyal to the Firefox web browser, and they're still big fans. Firefox beat out Google Chrome by a five-to-one margin. And, as always, the VLC media player is far more popular than any other Linux media player. For email clients, Mozilla Thunderbird remains on top. That's a bit surprising given how Thunderbird's development has been stuck in neutral for some time now. When it comes to text editors, I was pleased to see vim -- my personal favorite -- win out over its perpetual rival, Emacs. In fact, nano and Kate both came ahead of Emacs.

Leaders of the U.S. Senate Intelligence Committee said on Tuesday they were concerned about what they described as China's efforts to gain access to sensitive U.S. technologies and intellectual property through Chinese companies with government ties. From a report: Senator Richard Burr, the committee's Republican chairman, cited concerns about the spread of foreign technologies in the United States, which he called "counterintelligence and information security risks that come prepackaged with the goods and services of certain overseas vendors. The focus of my concern today is China, and specifically Chinese telecoms (companies) like Huawei and ZTE that are widely understood to have extraordinary ties to the Chinese government," Burr said. Senator Mark Warner, the committee's Democratic vice chairman, said he had similar concerns. "I'm worried about the close relationship between the Chinese government and Chinese technology firms, particularly in the area of commercialization of our surveillance technology and efforts to shape telecommunications equipment markets," Warner said.

YouTube CEO Susan Wojcicki won't divulge her biggest fear about competing with Facebook, but she will give them some free advice. From a report: "They should get back to baby pictures," Wojcicki said Monday at the Code Media conference in Huntington Beach, California. Video has been an obsession for Facebook, as it tries to swipe the most advertising dollars migrating off television before YouTube can get them. Facebook has been aggressively advancing the number of clips and live streams that bubble up to the top of your News Feed and has rolled out a central hub for TV-like programming called Watch. "You always have to take competition seriously. You don't win by looking backwards; you win by looking at your customers and looking forward," she said.

Microsoft has revealed its plans to use blockchain distributed-ledger technologies to securely store and manage digital identities, starting with an experiment using the Microsoft Authenticator app. From a report: Microsoft reckons the technology holds promise as a superior alternative to people granting consent to dozens of apps and services and having their identity data spread across multiple providers. It highlights that with the existing model people don't have control over their identity data and are left exposed to data breaches and identity theft. Instead, people could store, control and access their identity in an encrypted digital hub, Microsoft explained. To achieve this goal, Microsoft has for the past year been incubating ideas for using blockchain and other distributed ledger technologies to create new types of decentralized digital identities.

The medical profession has an ethic: First, do no harm. Silicon Valley has an ethos: Build it first and ask for forgiveness later. Now, in the wake of fake news and other troubles at tech companies, universities that helped produce some of Silicon Valley's top technologists are hustling to bring a more medicine-like morality to computer science, the New York Times reporter. From the report: This semester, Harvard University and the Massachusetts Institute of Technology are jointly offering a new course on the ethics and regulation of artificial intelligence. The University of Texas at Austin just introduced a course titled "Ethical Foundations of Computer Science" -- with the idea of eventually requiring it for all computer science majors. And at Stanford University, the academic heart of the industry, three professors and a research fellow are developing a computer science ethics course for next year. They hope several hundred students will enroll. The idea is to train the next generation of technologists and policymakers to consider the ramifications of innovations -- like autonomous weapons or self-driving cars -- before those products go on sale.

An anonymous reader quotes a report from VTDigger: Cable television giant Comcast is suing the Vermont Public Utility Commission over the panel's decision to require the company to expand its network and step up support for community access TV if it wants to continue doing business in Vermont. A key issue is the services Comcast must provide to local community access systems that carry municipal government and school board meetings and other local events. The 26 community access systems have been pushing -- against resistance by Comcast -- for high-definition video, greater ability to operate from remote locations, and inclusion in the interactive program guides that Comcast customers can use to decide what to watch. The PUC -- formerly known as the Public Service Board -- in January issued a new 11-year permit for Comcast to operate in Vermont. In July the panel rejected the company's request to drop some of the conditions attached to the permit.

In a lawsuit filed Monday in U.S. District Court in Burlington, Comcast argued that the PUC "exceeded its authority under federal and Vermont law" by imposing "numerous conditions on Comcast's continued cable operations in the state that are arbitrary, unprecedented and will ultimately harm local cable subscribers by resulting in millions of dollars in increased cable costs." It said the commission "did so despite overwhelming record evidence that Vermont cable subscribers do not want to incur any additional costs or fees for the kinds of conditions imposed" in the commission's January order.

According to a report (paywalled) from The Information, Amazon is designing a custom artificial intelligence chip that would power future Echo devices and improve the quality and response time of its Alexa voice assistant. "The move closely followers rivals Apple and Google, both of which have already developed and deployed custom AI hardware at various scales," reports The Verge. From the report: While Amazon is unlikely to physically produce the chips, given its lack of both fabrication experience and a manufacturing presence in China, the news does pose a risk to the businesses of companies like Nvidia and Intel. Both companies have shifted large portions of their chipmaking expertise to AI and the future of the burgeoning field, and both make money by designing and manufacturing chips for companies like Apple, Amazon, and others. Amazon, which seeks to stay competitive in the smart home hardware market and in the realm of consumer-facing AI products, has nearly 450 people with chip expertise on staff, reports The Information, thanks to key hires and acquisitions the e-commerce giant has made in the last few years. The plan is for Amazon to develop its own AI chips so Alexa-powered products in its ever-expanding Echo line can do more on-device processing, instead of having to communicate with the cloud, a process that increases response rate times.

AmiMoJo shares a report from Ars Technica: Earlier this week, the European Parliament voted 384 to 153 to review whether Daylight Saving Time is actually worth it. Although the resolution it voted on was non-binding, the majority reflected a growing dissatisfaction with a system that has been used by the U.S., Canada, most of Europe, and regions in Asia, Africa, and South America for decades. The resolution asked the European Commission to review the costs and benefits of Daylight Saving Time. If the EU were to abolish Daylight Saving Time, it would need approval of the majority of EU member states and EU Parliament members.

"We think that there's no need to change the clocks," Ireland Member of European Parliament (MEP) Sean Kelly said to Deutsche Welle. "It came in during World War One, it was supposed to be for energy savings -- the indications are that there are very few energy savings, if any -- and there are an awful lot of disadvantages to both human beings and animals that make it outdated at this point."

An anonymous reader quotes a report from The Associated Press: Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows. At the current rate, the world's oceans on average will be at least 2 feet (61 centimeters) higher by the end of the century compared to today, according to researchers who published in Monday's Proceedings of the National Academies of Sciences. Sea level rise is caused by warming of the ocean and melting from glaciers and ice sheets. The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets. It confirms scientists' computer simulations and is in line with predictions from the United Nations, which releases regular climate change reports. Of the 3 inches (7.5 centimeters) of sea level rise in the past quarter century, about 55 percent is from warmer water expanding, and the rest is from melting ice. But the process is accelerating, and more than three-quarters of that acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.

ZDNet reports of a security flaw in Skype's updater process that "can allow an attacker to gain system-level privileges to a vulnerable computer." If the bug is exploited, it "can escalate a local unprivileged user to the full 'system' level rights -- granting them access to every corner of the operating system." What's worse is that Microsoft, which owns Skype, won't fix the flaw because it would require the updater to go through "a large code revision." Instead, Microsoft is putting all its resources on building an altogether new client. From the report: Security researcher Stefan Kanthak found that the Skype update installer could be exploited with a DLL hijacking technique, which allows an attacker to trick an application into drawing malicious code instead of the correct library. An attacker can download a malicious DLL into a user-accessible temporary folder and rename it to an existing DLL that can be modified by an unprivileged user, like UXTheme.dll. The bug works because the malicious DLL is found first when the app searches for the DLL it needs. Once installed, Skype uses its own built-in updater to keep the software up to date. When that updater runs, it uses another executable file to run the update, which is vulnerable to the hijacking. The attack reads on the clunky side, but Kanthak told ZDNet in an email that the attack could be easily weaponized. He explained, providing two command line examples, how a script or malware could remotely transfer a malicious DLL into that temporary folder.

According to new estimates by eMarketer, Facebook users in the 12- to 17-year-old demographic declined by 9.9 percent in 2017, or about 1.4 million total users. That's almost three times more than the digital measurement firm expected. There were roughly 12.1 million U.S. Facebook users in the 12- to 17-year-old demographic by the end of the year. Recode reports: There are likely multiple reasons for the decline. Facebook has been losing its "cool" factor for years, and young people have more options than ever for staying in touch with friends and family. Facebook also serves as a digital record keeper -- but many young people don't seem to care about saving their life online, at least not publicly. That explains why Snapchat and Instagram, which offer features for sharing photos and videos that disappear, are growing in popularity among this demographic. Overall, eMarketer found Facebook lost about 2.8 million U.S. users under 25 last year. The research firm released Facebook usage estimates for 2018 on Monday, and expects that Facebook will lose about 2.1 million users in the U.S. under the age of 25 this year.

MojoKid writes: Though the company has been evangelizing its new Snapdragon 845 Mobile Platform for a while now, Qualcomm is lifting the veil today on the new chip's benchmark performance profile. At the heart of the Snapdragon 845 is the new Kyro 385 CPU, which features four high-performance cores operating at 2.8GHz and four efficiency cores that are dialed back to 1.7GHz, all of which should culminate in a claimed 25 percent uplift over the previous generation Snapdragon 835, along with improved power efficiency. In addition, the Snapdragon 845's new Adreno 630 integrated GPU core should deliver a boost in performance over its predecessor as well, with up to a 30 percent increase in graphics throughput, allowing it to become the first mobile platform to enable room-scale VR/AR experiences. Armed with prototype reference devices, members of the press put the Snapdragon 845 through its paces and the chip proved to be anywhere from 15 to 35 percent faster, depending on workloads and benchmarks, with graphics showing especially strong. Next-generation Android smartphones and other devices based on the Snapdragon 845 are expected to be unveiled at Mobile World Congress in Barcelona at the end of this month.

An anonymous reader quotes a report from Los Angeles Times: The center core booster of SpaceX's Falcon Heavy didn't land on a floating sea platform as intended during last week's first test flight because it ran out of ignition fluid, company Chief Executive Elon Musk said Monday. Musk took to Twitter on Monday morning to give a few more updates on the Falcon Heavy's first flight. After liftoff, the rocket's two side boosters touched down simultaneously on land, eliciting cheers and applause from the crowd of SpaceX employees gathered in the company's Hawthorne headquarters, as seen on the launch livestream. Those two boosters, which were used in previous launches of SpaceX's workhorse Falcon 9 rocket, will not be reused again, Musk said in a post-launch news conference last week. But the center core booster ended up hitting the Atlantic Ocean at 300 mph and about 328 feet from the floating platform where it was supposed to land. Musk said Monday that there wasn't enough ignition fluid to light the outer two engines of the booster "after several three engine relights."

The Trump administration has released an infrastructure plan on Monday that proposes that the federal government considers selling off Ronald Reagan Washington National Airport and Washington Dulles International Airport. According to Trump's blueprint, the administration wants to allow federal agencies to divest assets if they "can demonstrate an increase in value from the sale would optimize the taxpayer value for federal assets." It also includes the George Washington and Baltimore Washington parkways, the Washington Aqueduct and the transmission assets of the Tennessee Valley Authority and Bonneville Power Administration on the list for "potential divesture." Politico reports: State and local agencies or the private sector may be better at managing assets currently owned by the federal government, the administration argues, and federal agencies should be able to "identify appropriate conditions under which sales would be made." They should also "delineate how proceeds would be spent." Under the administration's proposal, federal agencies would have to complete an analysis demonstrating an "increase in value from divestiture." Though technically owned by the federal government, both airports are operated by the Metropolitan Washington Airports Authority under a long-term lease agreement. The 53-page infrastructure plan lays out a vision to turn $200 billion in federal money into $1.5 trillion for fixing America's infrastructure by leveraging local and state dollars and private investment. "The White House says its plan will create $1.5 trillion for repairing and upgrading America's infrastructure," reports CNNMoney. "Only $200 billion of that, however, would come from direct federal spending. The rest is supposed to come from state and local governments, which are expected to match any federal allocation by at least a four-to-one ratio. States have gradually assumed more of the responsibility for funding infrastructure in recent years, and the White House says it wants to accelerate that trend."

As for how the money would be split up, the plan says that half of the new federal money, $100 billion, "would be parceled out as incentives to local government entities," reports CNNMoney. "An additional $20 billion would go toward 'projects of national significance' that can 'lift the American spirit,'" while another $50 billion will be designated "for rural block grants, most of which will be given to states according to a formula based on the miles of rural roads and the rural population they have," reports CNNMoney. "The rest of the money would support other infrastructure-related undertakings..."
