An anonymous reader quotes a report from IEEE Spectrum: Tumor cells that spread cancer via the bloodstream face a new foe: a laser beam, shined from outside the skin, that finds and kills these metastatic little demons on the spot. In a study published today in Science Translational Medicine, researchers revealed that their system accurately detected these cells in 27 out of 28 people with cancer, with a sensitivity that is about 1,000 times better than current technology. That's an achievement in itself, but the research team was also able to kill a high percentage of the cancer-spreading cells, in real time, as they raced through the veins of the participants. If developed further, the tool could give doctors a harmless, noninvasive, and thorough way to hunt and destroy such cells before those cells can form new tumors in the body.

Researchers led by Vladimir Zharov, director of the nanomedicine center at the University of Arkansas for Medical Sciences, tested their system in people with melanoma, or skin cancer. The laser, beamed at a vein, sends energy to the bloodstream, creating heat. Melanoma CTCs absorb more of this energy than normal cells, causing them to heat up quickly and expand. This thermal expansion produces sound waves, known as the photoacoustic effect, and can be recorded by a small ultrasound transducer placed over the skin near the laser. The recordings indicate when a CTC is passing in the bloodstream. The same laser can also be used to destroy the CTCs in real time. Heat from the laser causes vapor bubbles to form on the tumor cells. The bubbles expand and collapse, interacting with the cell and mechanically destroying it.

An anonymous reader shares a report: In April, Google announced a groundbreaking technology that could allow Android users to use their smartphones as hardware security keys whenever logging into Google accounts on their laptops or work PCs. Initially, the technology was made available for Chrome OS, macOS, and Windows 10 devices. Today, Google announced it is expanding this technology to iOS as well. Today's news means that iPhone and iPad users can now use their (secondary) Android smartphones as a security key whenever logging into their Google accounts on an iOS device. The technology works basically the same, as Google explained in April, at the Cloud Next 2019 conference.

Google has warned the Trump administration it risks compromising US national security if it pushes ahead with sweeping export restrictions on Huawei [Editor's note: the link may be paywalled; alternative source], as the technology group seeks to continue doing business with the blacklisted Chinese company. Financial Times: Senior executives at Google are pushing US officials to exempt it from a ban on exports to Huawei without a licence approved by Washington, according to three people briefed on the conversations. The Trump administration announced the ban after the US-China trade talks collapsed, prompting protests from some of the biggest US technology companies who fear they could get hurt in the fallout.

Google in particular is concerned it would not be allowed to update its Android operating system on Huawei's smartphones, which it argues would prompt the Chinese company to develop its own version of the software. Google argues a Huawei-modified version of Android would be more susceptible to being hacked, according to people briefed on its lobbying efforts. Huawei has said it would be able to develop its own operating system "very quickly."

"Apple's Dashboard is getting quietly removed from the company's upcoming macOS Catalina update," reports The Verge, citing Appleosophy and MacRumors. "The Dashboard first launched seven years ago with Mac OS X 10.4 Tiger in 2005 and saw its final update in 2011 with the launch of OS X 10.7 Lion." From the report: The app first introduced the concept of widgets to Apple's desktop operating system and became a hallmark of OS X design for more than a decade. In particularly, Dashboard became well known for its desktop Sticky Note feature and its overall skeuomorphic approach best emphasized by the clock, stocks, and calculator widgets, a design philosophy that formed the foundation of the first version of iOS that launched a few years after OS X Tiger. It wasn't until iOS 7 in 2013 that Apple would abandon that aesthetic for a flatter, more modern one that eventual carried back over to its desktop approach.

Since 2011, Dashboard has been accessible in various forms, but it's had none of its widget design or UI updated, making it a bit of an anachronism existing behind the scenes on macOS. With OS X 10.10 Yosemite, Apple disabled the application by default, but still allowed users to access it either as a hotkey overlay or its own separate space within Mission Control. Now, in macOS Catalina, it appears Dashboard is going away for good. Appleosophy tried to disable and enable the Dashboard via Terminal only for the system to show it as missing even after a forced reboot. The Launchpad overlay also shows the Dashboard app icon as a question mark, the same as with the broken up and effectively killed off iTunes.

An anonymous reader quotes a report from Ars Technica: iOS 13 will introduce Dark Mode to iPhones, iPads, and iPods for the first time. Apple brought Dark Mode to Macs via macOS Mojave last year, to much fanfare. As was the case there, Dark Mode doesn't actually change anything about the interface -- just the aesthetics. Apple showed Dark Mode running on the company's first-party apps for news, calendar, messages, and more. Dark Mode may also save battery life on devices with emissive OLED displays -- savings like that were discovered in our own tests comparing Android devices with LCD and OLED displays. But we'll have to test the new OS to be sure.

Every iOS update brings changes to key apps made by Apple itself, and most of the apps included with a new installation of iOS have seen some changes. Mail now allows you to mute certain conversations. Maps has a new, easier way of accessing saved locations. The upgrade to Apple Maps will bring far more detail to the overhead view of roads and landmarks, with this rolling out to the entire United States by the end of 2019 and "select countries" next year. Reminders has seen a ground-up interface overhaul, with natural-language processing similar to what's seen in third-party apps -- you'll be able to type the relevant details and Reminders will understand when and where the reminder should be set for. Apple is also adding a swipe-typing ability to its iOS keyboard for the first time, replicating something that has been available in third-party keyboards for years. Notes will have a new gallery view and support for shared folders. Safari will have new options to change text sizing, with per-website settings. The iPad's multitasking UI has also been overhauled, bringing a new window-based experience and an easier way to switch between apps in Slide Over mode. You'll also be able to plug thumb drives into newer iPads with USB-C.

Onstage at WWDC, Apple announced that iPad's software will now exist inside its own vertical OS. The new iPadOS doesn't look dramatically different from iOS 12, but the name change undoubtedly makes it easier for Apple to introduce functionality to iPads that won't exist in any capacity on the iPhone. Here's is the list of features it offers: 1. Chances are the best update is that desktop sites are now the default in Safari, hallelujah!!
2. You'll be able to bring widgets to the home screen that are just a swipe away. You'll also be able to fit more app icons on each screen.
3. Changes in iPadOS include an update to the Files app which will allow you share folders in iCloud drive, there's a new column view and you'll be able to grab files from USB-C flash drives.
4. You'll be able to bring up multiple windows of the same app, which wasn't previously possible and there are a lot of small interface changes that make it easier to multi-task with your larger screen real estate.
5. Apple Pencil latency is dropping from 20ms to 9ms, Apple is bringing a PencilKit developer API so that third-party app developers can integrate some new controls.

The NLNet Foundation is a non-profit supporting privacy, security, and the "open internet". Now the group has approved funding for the hybrid Libre RISC-V CPU/VPU/GPU, which will "pay for full-time engineering work to be carried out over the next year, and to pay for bounty-style tasks."

Long-time Slashdot reader lkcl explains why that's significant: High security software is irrelevant if the hardware is fundamentally compromised, for example with the Intel spying backdoor co-processor known as the Management Engine. The Libre RISCV SoC was begun as a way for users to regain trust and ownership of the hardware that they legitimately purchase.

This processor will be the first of its kind, as the first commercial SoC designed to give users the hardware and software source code of the 3D GPU, Video Decoder, main processor, boot process and the OS.

Shockingly, in the year 2019, whilst there are dozens of SoCs with full source code that are missing either a VPU or a GPU (such as the TI OMAP Series and Xilinx ZYNQ7000s), there does not exist a single commercial embedded SoC which has full source code for the bootloader, CPU, VPU and GPU. The iMX6 for example has etnaviv support for its GPU however the VPU is proprietary, and all of Rockchip and Allwinner's offerings use either MALI or PowerVR yet their VPUs have full source (reverse engineered in the case of Allwinner).

This processor, which will be quad core dual issue 800mhz RV64GC and capable of running full GNU/Linux SMP OSes, with 720p video playback and embedded level 25fps 3D performance in around 2.5 watts at 28nm, is designed to address that imbalance. Links and details on the Libre RISC-V SoC wiki.

The real question is: why is this project the only one of its kind, and why has no well funded existing Fabless Semiconductor Company tried something like this before? The benefits to businesses of having full source code are already well-known.

An anonymous reader quotes a report from ZDNet: Russian authorities have moved closer to implementing their plan of replacing the Windows OS on military systems with a locally-developed operating system named Astra Linux. Last month, the Russian Federal Service for Technical and Export Control (FSTEC) granted Astra Linux the security clearance of "special importance," which means the OS can now be used to handle Russian government information of the highest degree of secrecy. Until now, the Russian government had only used special versions of Windows that had been modified, checked, and approved for use by the FSB. Astra Linux is a Debian derivative developed by Russian company RusBITech since 2008, the report says. "RusBITech initially developed the OS for use in the Russian private market, but the company also expanded into the local government sector, where it became very popular with military contractors."

Microsoft still hasn't officially confirmed the existence of its rumored Windows Lite operating system, but the software giant is dropping some pretty big hints about the future of Windows today. From a report: Nick Parker, Microsoft's corporate vice president of consumer and device sales, appeared on stage at Computex today to detail the company's vision for a modern operating system. While Parker didn't unveil Windows Lite, a rumored lightweight version of Windows for dual-screen and Chromebook-like devices, he did reveal how Microsoft is preparing for new device types. These new devices will require what Microsoft calls a "modern OS," that includes a bunch of "enablers" like seamless updates. We've seen various promises about Windows Updates being improved over the years, but Microsoft is now promising that "modern OS updates are invisibly done in the background; the update experience is deterministic, reliable, and instant with no interruptions!" No interruptions and done in the background sounds very different from the Windows Update experience available on Windows 10 today, and it sounds far more Chrome OS-like. This "modern OS" is also secure by default according to Microsoft, meaning the state is separated from the OS and compute is "separated from applications," which sounds a lot more cloud-powered than what we're used to today. Microsoft also wants this modern OS to work with 5G connectivity, and to include a variety of inputs like pen, voice, touch, even gaze.

Amidst an escalating trade war and political tensions with the US, Beijing officials have decided to develop a custom operating system that will replace the Windows OS on computers used by the Chinese military. From a report: The decision, while not made official through the government's normal press channels, was reported earlier this month by Canada-based military magazine Kanwa Asian Defence. Per the magazine, Chinese military officials won't be jumping ship from Windows to Linux but will develop a custom OS. Thanks to the Snowden, Shadow Brokers, and Vault7 leaks, Beijing officials are well aware of the US' hefty arsenal of hacking tools, available for anything from smart TVs to Linux servers, and from routers to common desktop operating systems, such as Windows and Mac. Since these leaks have revealed that the US can hack into almost anything, the Chinese government's plan is to adopt a "security by obscurity" approach and run a custom operating system that will make it harder for foreign threat actors -- mainly the US -- to spy on Chinese military operations.

Huawei's home-grown operating system -- codenamed HongMeng -- that's set to replace Android once the Huawei ban from Google comes into full effect, will be commercially rolled out next month, a Middle East head for the firm revealed exclusively to TechRadar Middle East. From a report: On May 20, Google announced that it would partially cut off Huawei devices from its Android operating system but was given an extension till August 19 by the US White House. "Huawei knew this was coming and was preparing. The OS was ready in January 2018 and this was our 'Plan B'," said Alaa Elshimy, Managing Director and Vice President of Huawei Enterprise Business Group Middle East. "We did not want to bring the OS to the market as we had a strong relationship with Google and others and did not want to ruin the relationship. Now, we are rolling it out next month."

The letter is addressed to the maintainers of Linux distributions who elect to ship custom GTK and icons themes by default in lieu of upstream defaults. From a report: By publicizing the issues they feel stem from the practice of "theming" it's hoped that distros and developers might work together to create a "healthier GNOME third party app ecosystem." So what's the actual rub here? It often feels like the ability to control how our desktop looks and works is part of some unwritten Linux constitution, one we're all secret adherents to.

But theming on the GNOME platform isn't all it seems. It's not without complications or compromises. As superficial as these changes might seem, usability is actually more than skin deep. Now, elephant in the room time: many leading Linux distros use custom GTK themes and icon sets as a way create a brand identity for themselves; an experience that feels uniquely their own. This includes Ubuntu (with Ambiance and Yaru), Linux Mint (with Mint-X), Pop OS (with Pop GTK) and Manjaro.

Veteran software developer firm Panic, which has made its name through high-end Mac software as well as titles such as Firewatch, is expanding its work in games and moving in a very unexpected direction. This week, Panic unveiled Playdate, a tiny, yellow Game Boy-like device with a black-and-white screen, a few chunky buttons, and... a hand crank for controlling quirky games. From a report: Playdate is adorable and exciting and fun and technically impressive. They're making their own hardware (in conjunction with Swedish device makers Teenage Engineering). They wrote their own OS (there's no Linux). It has a high resolution 400 x 240 black and white display with no backlighting. It has a crank. It's going to cost only $149 -- $149! -- and that includes a "season" of 12 games from an amazing roster of beloved video game creators, delivered every Monday for 12 weeks. The idea of a new upstart, a company the size of Panic -- with only software experience at that -- jumping into the hardware game with a brand new platform harkens back to the '80s and '90s. But even back then, a company like, say, General Magic or Palm, was VC-backed and aspired to be a titan. To be the next Atari or Commodore or Apple.

In today's world all the new computing devices and platforms come from huge companies. Apple of course. All the well-known Android handset makers building off an OS provided by Google. Sony. Nintendo. Panic is almost cheating in a way because they're tiny. The Playdate platform isn't competing with the state of the art. It's not a retro platform, per se, but while it has an obviously nostalgic charm it is competing only on its own terms. Its only goal is to be fun. And aspects of Playdate are utterly modern: Wi-Fi, Bluetooth, apps and software updates delivered over-the-air. They're taking advantage of an aspect of today's world that is brand new -- the Asian supply chain, the cheapness of Asian manufacturing, the cheapness of CPU and GPU cycles that allows things like Raspberry Pi to cost just $35.

An anonymous reader shares a report: Project Campfire turned up in the Chromium world this past August. The intent was to let a Chromebook boot not just into Chrome OS but directly into another operating system such as Linux or Windows. I thought the latter was a positive outcome since it would allow Chromebooks to natively run Windows desktop apps on a Chromebook, and add value to devices. Unfortunately, the project is shutting down. Spotted in code, there are comments and code removals that make it clear Project Campfire is being deprecated.

sfcrazy writes: Mark Shuttleworth, founder and CEO of Canonical, summed it in a few words: "I think the bigger challenge has been that we haven't invented anything in the Linux that was like deeply, powerfully ahead of its time." He also said that "if in the free software community we only allow ourselves to talk about things that look like something that already exists, then we're sort of defining ourselves as a series of forks and fragmentations." He added that it seems the desktop Linux people want to be angry at something. We wanted to do amazing things with Unity but the community won't let us do it, so here we are. He also commended Google folks for what they have built for Chrome OS.

"2019 is truly, finally shaping up to be the year of Linux on the desktop," writes PC World's senior editor, adding "Laptops, too!" But most people won't know it. That's because the bones of the open-source operating system kernel will soon be baked into Windows 10 and Chrome OS, as Microsoft and Google revealed at their respective developer conferences this week... Between lurking in Windows 10 and Chrome OS, and the tiny portion of actual Linux distro installs, pretty much any PC you pick up will run a Linux kernel and Linux software. Macs won't, but it's based on a Unix-like BSD system that already runs many Linux apps with relative ease (hence Apple's popularity with developers).

You have to wonder where that leaves proper Linux distributions like Ubuntu and Linux Mint, though. They already suffer from a minuscule user share, and developers may shift toward Windows and Chrome if the Linux kernels in those operating systems get the same job done. Could this fruit wind up poisonous over the long term? We'll have to see. That said, Linux is healthier than ever. The major distros are far more polished than they used to be, with far fewer hardware woes than installs of yesteryear. You can even get your game on relatively well thanks to Valve's Proton technology, which gets many (but not all) Steam games working on Linux systems. And hey, Linux is free.

Normal users may never be aware of it, but 2019 may finally be the year of Linux on the desktop -- just not Linux operating systems on the desktop.

An anonymous reader quote CRN: IBM chief executive Ginni Rometty and Microsoft CEO Satya Nadella shared the keynote-session stage with Red Hat CEO Jim Whitehurst at the 15th-year installment of the open-source technology event. Rometty talked up IBM's pending $34 billion acquisition of Red Hat and their future relationship. Nadella was there to help herald Azure Red Hat OpenShift, the new enterprise-grade Kubernetes platform that allows developers to run container-based applications on-premises and across Azure, Microsoft's public cloud. Microsoft will jointly manage the platform with Red Hat.

"The CEOs of (two of the) largest technology companies in the world on stage in the same keynote, and it's a Red Hat keynote," Whitehurst said. "Who would have expected that? Hopefully it says something about open source and our role, but it also certainly says something about those companies and their desire to serve customers and their desire to embrace open source."
During the presentation Red Hat's CEO told Microsoft's CEO, "To be blunt, five years ago we had, I guess to be polite, it would be called an adversarial relationship."

Earlier in the presentation, Microsoft CEO Satya Nadella had said, "Everything has a time," adding later that the Red Hat/Microsoft partnership "is driven by what I believe is fundamentally what our customers expect of us. They expect us to...really interoperate, be committed to open source."

At Google's I/O developer conference this past week, Android and Chrome chief Hiroshi Lockheimer offered some rare insight into Fuchsia, albeit at a very high level, in front of public audiences. The Verge reports: What we do know about Fuchsia is that it's an open source project, similar to AOSP, but could run all manner of devices, from smart home gadgets to laptops to phones. It's also known to be built on an all-new, Google-built kernel called "zircon," formerly known as "magenta," and not the Linux kernel that forms the foundation of Android and Chrome OS.

"We're looking at what a new take on an operating system could be like. And so I know out there people are getting pretty excited saying, 'Oh this is the new Android,' or, 'This is the new Chrome OS,'" Lockheimer said. "Fuchsia is really not about that. Fuchsia is about just pushing the state of the art in terms of operating systems and things that we learn from Fuchsia we can incorporate into other products." He says the point of the experimental OS is to also experiment with different form factors, a hint toward the possibility that Fuchsia is designed to run on smart home devices, wearables, or possibly even augmented or virtual reality devices. "You know Android works really well on phones and and you know in the context of Chrome OS as a runtime for apps there. But Fuchsia may be optimized for certain other form factors as well. So we're experimenting." Lockheimer provided some additional details at a separate Android fireside chat held at Google I/O today. "It's not just phones and PCs. In the world of [the Internet of Things], there are increasing number of devices that require operating systems and new runtimes and so on. I think there's a lot of room for multiple operating systems with different strengths and specializations. Fuchsia is one of those things and so, stay tuned," he told the audience.

In a rare article detailing insights about its staff's efforts in securing its own internal infrastructure, Microsoft has shared some very insightful advice on how companies could reduce the risk of having a security breach. From a report: The central piece of this article is Microsoft's recommendation in regards to how companies should deal with administrator accounts. Per Microsoft's Security Team, employees with administrative access should be using a separate device, dedicated only for administrative operations. This device should always be kept up to date with all the most recent software and operating system patches, Microsoft said. "Provide zero rights by default to administration accounts," the Microsoft Security Team also recommended. "Require that they request just-in-time (JIT) privileges that gives them access for a finite amount of time and logs it in a system." Furthermore, the OS vendor also recommends that administrator accounts should be created on a separate user namespace/forest that cannot access the internet, and should be different from the employee's normal work identity.

At Google I/O in Mountain View, Google said "all devices [Chromebook] launched this year will be Linux-ready right out of the box." From a report: In case you've missed it, last year, Google started making it possible to run desktop Linux on Chrome OS. Since then, more Chromebook devices are able to run Linux. Going forward, all of them will be able to do so, too. Yes. All of them. ARM and Intel-based.
