Tech Titans Downplay Meltdown And Spectre Patches' Performance Hits PDF Print E-mail

tech giants talkAmazon, Apple, Google, and Microsoft are reporting that their computer performance has been largely unaffected by the patches for Meltdown and Spectre. The news of the Meltdown and Spectre security vulnerabilities, which together affect almost all modern CPUs, has been sweeping the web since the start of the year. The fix for Meltdown, an OS-level method of mitigation called kernel page table isolation (KPTI), has now been implemented for major operating systems, including Linux, macOS, iOS, Android, and Windows. Mitigations for Spectre, which is actually two different vulnerabilities, are currently less understood, however. Fixes, so far, have involved program-level, OS-level, and hardware-level patching, but it seems there isn’t a single solution to both of the Spectre vulnerabilities. Meltdown has a singular fix across all operating systems because the vulnerability results from an optimization present in specific CPUs, namely Intel’s and some of ARM’s. With no way to fix the CPUs, the only way is to apply a heavy-handed approach that nullifies the optimization within the OS--KPTI. It was known that KPTI would, in theory, have a real performance cost. The earliest tests on Linux with worst case scenarios showed performance drops of up to 30%...The giants are saying more and visiting OUR FORUM you can find out what they are saying.
Microsoft will end free Windows 10 Update for Assistive Technology users PDF Print E-mail

windows 10 free upgradeWhile Microsoft indicated that it would be stopping the free upgrade for assistive tech users to Windows 10 last year, the update continued past the deadline, leading to some confusion about the situation. Likely in response to coverage around the update extension, Microsoft has issued a clarification on its page, spelling out when the upgrade offer will be expiring. If you use assistive technologies, you can upgrade to Windows 10 at no cost as Microsoft continues our efforts to improve the Windows 10 experience for people who use these technologies. Please take advantage of this offer before it expires on January 16, 2018. With the free Windows 10 Update having expired over a year ago, Microsoft’s olive branch to users of assistive technologies is heartening, especially as the firm has worked to improve support in Windows 10 both in user-facing tools like narrator, developer tools, and built-in apps. Some of the improvements you can expect to see are in MIcrosoft Edge, Mail, Cortana, and Groove.  For more visit OUR FORUM and follow the provided link.
Spectre and Meltdown are just as bad as you think PDF Print E-mail

meltdown & spectreWhen security researchers encounter a security vulnerability, it’s usually because a programmer messed up somewhere. A buffer overflow here. An unsanitized input there. They all add up to introduce an element of insecurity. Meltdown and Spectre are different. These two threatening issues aren’t the result of the program running on the computer, but rather the computer itself. Flaws buried deep in the architecture of most modern CPUs have presented a golden opportunity for bad actors to access privileged information held in memory. Most computers contain iron-clad spaces where data can pass securely in an unencrypted, visible form. These work by limiting the access to that data from other applications and processes. But Meltdown and Spectre undermine these safeguards. If exploited, they could result in an adversary accessing things like passwords and privileged data. Here’s everything you need to know about the current security nightmare du jour. Meltdown was dubbed by Daniel Gruss, one of the researchers that discovered the vulnerability, as “probably one of the worst CPU bugs ever found.” It primarily affects CPUs made by Intel, although ARM has introduced countermeasures to protect it. While Meltdown and Spectre are both similar, what distinguishes Meltdown is that it pertains to the protective barriers between the underlying operating system and applications running on it. Remember when I said that Meltdown affects the barrier between the operating system and the application? Well, Spectre muddies the water between applications, allowing Program A to steal the secrets of Program B...Learn a lot more on Meltdown & Specter on OUR FORUM.
CES 2018 is where you'll start caring about 5G PDF Print E-mail

5G communicationsThis year, the world's biggest consumer electronics show will shine a light on the next-gen wireless technology that will shape the coming decade. At this year's CES you'll hear plenty of talk about driverless cars, connected homes and the internet of things. (Yes, we promise IoT, perhaps the buzziest of tech trends, is more than just hackable baby monitors and $400 internet-connected juicers.) Here's the technology that will drive all of those innovations over the next decade: 5G. The shorthand tag "5G" stands for fifth-generation wireless technology. Those broadband-like wireless speeds you're getting on your phone now? That's 4G technology. So just think about what happens next.If you're excited about the prospects, you aren't alone. Tech observers see 5G as the foundation for a host of other trends. At last year's CES, Qualcomm CEO Steve Mollenkopf described 5G as the biggest thing since the introduction of electricity. Remember, a lot of work needs to be done for 5G to achieve broad scale. But with networks set to go live by 2019 and coverage reaching 20 percent of the population by 2023, now's the time to start caring about it...This is just a few of the things we will start caring about at CES 2018, learn more at OUR FORUM.
Microsoft has killed its Groove Music streaming service PDF Print E-mail

The day has finally come – Microsoft has retired its Groove Music streaming service across all platforms. Back in October of last year, Microsoft announced it was winding down support for its "Groove Music Pass", and all features related to streaming and purchasing content via the Groove Music app. Since its formal debut in 2015, with the release of Windows 10, Microsoft's music streaming service failed to gain traction among strong competition. This eventually led to Microsoft scheduling a shut-down of the service for December 31, 2017. While a new year passed and Groove Music was still fully operational, as of January 2, the online elements of the app have been shut down entirely. Music can no longer be streamed through Groove apps, songs can no longer be purchased from the Microsoft Store and music video playback has been shuttered. Radio, Explore and Recommended features of the app have also been removed. By opening the Microsoft Store app on any Windows 10 device, users will now be greeted by a new menu, lacking the music tab. For remaining Groove Music users, the local playback features of the app still remain functional following the shutdown. The app also still supports streaming via OneDrive, which allows local files to be played across various devices. But for those looking for a full-fledged music experience, better services can be found elsewhere. Microsoft recommends users switch to Spotify, with a partnership between the two companies that allows users to seamlessly migrate to the service. With apps across Windows 10, Xbox One and mobile devices (yes, that includes Windows 10 Mobile), the service is among the most universal on the market. Source: windowscentral

radeon graphicsTo begin the year, Intel’s Indian website has published a small number of details regarding Intel’s first ‘Intel Radeon RX Vega Graphics’ processor. Within the table of overclockable processors, accompanying the Core i9, Core i7-X and 8th Generation K processors are listed the Intel Core i7-8809G, a quad-core processor with two sets of graphics options listed. The Core i7-8809G is not a part that Intel has formally announced in a press release, but on Intel’s overclocking webpage here it as listed as being a quad-core processor with hyperthreading, supporting a 3.1 GHz base frequency, having an 8 MB L3 cache, a 100W ‘Target’ TDP, and supporting two channels of DDR4-2400. Intel lists both sets of graphics: the integrated graphics (iGPU, or IGP) as 'Intel HD Graphics 630', and the package graphics (pGPU) as ‘Radeon RX Vega M GH Graphics'...Follow this on OUR FORUM.

Recently, we discovered an extension with a built-in JavaScript cryptocurrency miner and today yet another popular Chrome extension has been caught pushing a cryptocurrency miner to its users without their knowledge. Google Chrome extension “Archive Poster” was secretly running a mining tool in the background. The extension with over 105,000 users has been pulled from the Google Chrome Web Store. The extension was reportedly mining Monero, open-source cryptocurrency created in April 2014. The extension Archive Poster is a simple tool for Tumblr to “reblog, queue, draft, and like posts right from another blog’s archive.” The developer reportedly updated the app in early December and implemented the Coinhive in-browser miner, the users’ negative feedback about high CPU usage dates back to December 9. “Do not use this extension as it comes loaded with a cryptocurrency mining script. Once installed it makes requests to coinhive which eats up your CPU time and slows your computer down massively. Avoid,” a user said. If you have Archive Poster extension installed on your Windows PC, you will notice a spike in CPU activity whenever Chrome is running. We recommend you to remove the extension from your computer as the extension won’t be updated with a fix anytime soon. VIA Bleeping Computer
