During the recent SC19 supercomputing conference, the top semiconductor and systems vendors discussed and demoed the highest-performance computing solutions in the world. While it's easy to imagine these platforms solving some of the most challenging problems, and simulating everything from the human genome to climate change, there are thousands of other applications that can benefit as well.

When Linux first emerged from its cocoon in a frenzied Usenet thread, it is doubtful that almost anyone imagined the project would ascend to global prominence. Even more astonishingly, its dominance was driven as much, if not more, by its adoption by the private sector -- although it posed an antithesis to its business model -- as by any of its other notable traits.

Every decade the wireless industry transitions to a new cellular technology, and every generation there are doubts about it. This continues with 5G. I have heard from consumers and even people within the industry that there is "no need for 5G," "5G is only for businesses," "5G won't be available until 2025," "mmWave is only for fixed wireless access," and "radiation from mmWave is harmful."

Today is Veterans Day. I got a note last week from Joe Sestak, one of the shrinking field of United States presidential candidates, reminding me that we should observe a moment of silence in recognition of our veterans today. We've asked these people to put their lives on the line for us, and we get a day to offer our thanks. Giving our thanks is the least we can do.

It seems strange to me that our governments haven't been more aggressive about protecting the environment, given that the cost of not doing so poses an existential risk to the human race. It seems insane to me as we watch parts of the country burn and other parts of the country drown that we're still arguing about climate change rather than coming together to do something about it.

Samsung has called quits on its effort to provide a full Linux desktop platform for Android. In an email to beta testers last week, Samsung said it would not support its Linux on DeX beta program for future OS and device releases. Samsung's announcement coincides with Google's release of the Android 10 OS update and its rollout on Samsung phones. Neither company will provide Linux on DeX support.

A new flagship smartphone, a slick refresh of Pixelbook Go, some home gadget improvements and a revamp of its wireless earbuds highlighted Google's annual hardware event in New York City. The latest models of Google's flagship smartphone, Pixel 4 and Pixel 4 XL, base priced at $799 and $899 respectively, will have wider distribution, as they'll be available from all major U.S. carriers.

One of the interesting and somewhat underappreciated aspects of the recent Qualcomm wireless event is that 5G will make realistic AR avatars possible. This advance will be possible because with high bandwidth and very low latency, processing could shift from the device to the cloud. Coupled with the rollout of distributed data centers, this means you could have realistic virtual pets and friends.

Subscription models have taken hold in everything from software to smartphones, and now Sonos is testing the idea in the premium wireless speaker market. The Santa Barbara, California, company has launched a pilot program limited to 500 homes in the Netherlands, which allows consumers to gain access to Sonos hardware for the equivalent of about $16.46 a month.

One of the last major initiatives former CEO Steve Ballmer launched before he left Microsoft was its Surface effort. It was designed to address the concern that the iPod would take over the PC world. During the Surface launch last week, it wasn't hard to see that Ballmer was right conceptually. It just took Satya Nadella to execute, showcasing that Ballmer didn't have a strategic problem.

Microsoft has launched a slew of new devices designed to reshape the world: the Surface Laptop 3, the Surface Pro 7, the Surface Pro X, Surface Earbuds, and the upcoming Surface Neo and Surface Duo. "The next decade will be about creation, and amplifying what we can do as humans," said Microsoft CEO Satya Nadella at Microsoft Surface 2019 in New York City.

Elon Musk and Jack Ma floated some radical ideas last week. Two of the most powerful men in the world, both have invested heavily in AI. Ma, who is the Alibaba Group cofounder and a huge advocate for the 12-hour a day six-day Chinese work week in tech, indicated that he believed AI would reduce the work week from 72 hours, where it now is in China, to 12 hours -- that is, three 4-hour workdays.

A new collaboration between Dell Technologies and Google has produced the world's first enterprise-class Chromebook. The companies have announced their partnership to bring new capabilities and services to Dell's Unified Workspace strategy. Google launched its Chrome Enterprise capabilities in 2017 to give enterprises critical features like advanced security protections and fleet management.

Owners of iPhones looking for an extra measure of protection when using applications and logging into websites can get it with a new dongle from Yubico. Its new YubiKey 5Ci, which retails for $70, supports both USB-C and Apple's Lightning connectors on a single device. The dual connectors can give security-conscious consumers and enterprise users strong hardware-backed authentication.

Startup chip developer Cerebras has announced a breakthrough in high-speed processor design that will hasten the development of artificial intelligence technologies. Cerebras unveiled the largest computer processing chip ever built. The new chip, dubbed "Wafer-Scale Engine" -- pronounced "wise" -- is the heartbeat of the company's deep learning machine built to power AI systems.

The latest Windows 10 update hasn't gone smoothly for many users due to a conflict with an outdated driver for Intel's Rapid Storage Technology. This is somewhat ironic in that RST was designed to improve the performance of storage hardware. Certain versions have slowed the install process, and in some cases the program has made installation of the Version 1903 Windows 10 update impossible.

Qualcomm Technologies aims to push the speed limits of mobile gaming with the added features in its Snapdragon Mobile Platform. The Snapdragon 855 Plus Mobile Platform, its newest processor, performs graphics functions 15 percent faster. It will show up in new devices later this year. Snapdragon 855 Plus is an update to the flagship Snapdragon 855, released earlier this year.

A security researcher has found a flaw in the popular video conferencing app Zoom that could be used to turn on the camera on a Macintosh computer without a user's permission. The vulnerability allows any website to forcibly join a user to a Zoom call, with their video camera activated, without a user's permission, explained Jonathan Leitschuh, a senior software engineer at Gradle.

After reading about the departure of Jony Ive, I'm trying to wrap my head around Apple without a design focus. Now this isn't as hard as you might think, given the last truly successful Apple product came out around a decade ago and was called the "iPad." It is also somewhat ironic that Apple just effectively relaunched the iPod, the product that Steve Jobs rode to Apple's massive success.

The next big Raspberry Pi thing is now here, with lots more computing power and more options. The Raspberry Pi Foundation has announced the availability of Raspberry Pi 4, a comprehensive upgrade that touches nearly every element of the computing platform. Users have a choice of three memory capacities. The entry-level 1 GB RAM retains the signature $35 price; 2 GB costs $45; 4 GB sells for $55.

E3, the Electronic Entertainment Expo, was in full swing in Los Angeles this week. The annual trade show for the video game industry was not without a few surprises, a few disappointments and as usual a few companies that opted to forego the whole thing. Sony was among the companies that chose to skip the event, while rival Microsoft was present only via its annual press conference.

While trade disputes between countries are nothing new and seldom are remembered, the ongoing one between China and the United States may change the course of the electronics industry going forward. In the beginning of the dispute proposed tariffs excluded electronics for the most part. The U.S. even modified some initial proposals to avoid impacting Apple and other U.S. tech companies.

Microsoft whetted the appetite of power-hungry Xbox gamers at its E3 preview, with new details about its next-generation gaming console code-named "Project Scarlett." Expected to arrive in time for the 2020 holidays, the new Xbox will have a custom-designed AMD processor based on the latest Zen 2 and Radeon RDNA technology. Scarlett also will have high-bandwidth GDDR6 memory and a next-gen SSD.

Apple dangled the next versions of iOS, macOS and watchOS before developers' eyes during the keynote event at its World Wide Developers Conference in San Jose, California. In this round of operating system upgrades, Apple seems focused on improvements. "They're polishing a number of aspects of the operating systems, " said Ross Rubin, principal analyst at Reticle Research.

Privacy, a new muscular Mac Pro workstation, and the debut of iPadOS were topline items at Apple's WWDC keynote. During its more than two-hour presentation, Apple emphasized new features in its products aimed at protecting users' data and privacy. "At Apple, we believe privacy is a fundamental human right and we engineer it into everything we do," Craig Federighi told the enthusiastic crowd.

Like a lot of folks, I'm a tad sick of Intel. Last month we learned of its second big security scandal in as many years. Once again, the company not only neglected to disclose the problems in a timely way but also lacked a plan to recall the failed parts. Once again, buyers likely will have to cripple their Intel processors if they want to use them safely.

Aside from malware and viruses, nothing has the potential to be more dangerous to your computer's health than power outages. Here is how to ensure your computer keeps it boot on when a power failure turns the lights off. With the approach of the turbulent summer season, it is important to know what kills the electrical lifeline, how to safeguard your digital gear from fatal reboot disease.

Qualcomm just lost its seemingly no-lose case against the FTC, largely because it seems the judge was only physically in the room during the trial. The ruling makes it look like she and I observed very different trials. In addition, the U.S. apparently declared war against Huawei, which actually could benefit Huawei. The result of both efforts effectively could be to give the 5G market to China.

British mobile device software design firm ARM has ordered its staff to stop working with Chinese smartphone giant Huawei, in compliance with a ban issued by President Trump. Under an executive order he signed last week, foreign companies and individuals are prohibited from buying United States technology and services without first obtaining special approval from the U.S. government.

I went to Lenovo Accelerate last week and feasted my eyes on one of the most innovative PCs I've ever seen. However, as I absorbed the rest of Lenovo's announcements, I realized I was looking at just the tip of what could be a significant coming change in personal computers -- one that could eclipse every change we have seen so far. Lenovo's "one more thing" is a coming foldable screen laptop.
