  • Here Is A Linux 4.5-rc2 Kernel To Play With The New AMDGPU Functionality

    With a report that Linux 4.5-rc2 manages to improve the AMD R9 Fury (Fiji) performance, I spun up a Linux 4.5-rc2 kernel this morning for easing those wanting to test the AMDGPU driver atop Ubuntu.

    While the Ubuntu Mainline Kernel PPA ships with the AMDGPU DRM driver enabled, it doesn't yet enable the new PowerPlay Kconfig option for getting faster performance on hardware like Fiji, Tonga, etc. Their kernel also doesn't ship with the experimental CIK GPU support enabled. Thus I spun a 4.5-rc2 kernel this morning that enables these extra AMDGPU tunables.

  • AMDGPU Driver Said To Be Much Faster With Linux 4.5-rc2 Kernel

    With Linux 4.5-rc2 that was released last night, the new AMDGPU DRM driver is supposedly much faster compared to last week's 4.5-rc1 kernel.

    A Phoronix reader commented, "I read through the changelog and saw that there were several amdgpu patches. I just built this RC, rebooted, and ran some 3d benchmarks an the result is: a) double or quadruple the framerates that I got with RC1, and Cool no more overheating. I have the same model R9 Fury that Michael excluded from the last round of benchmarks due to performance/stability problems."

  • PHP maintains an enormous lead in server-side programming languages

    The venerable web programming language PHP is a source of frequent complaints and frustration, but according to a report W3Techs released today, it doesn't seem to be going away any time soon. W3Techs' web server survey looks for technologies in use by sites in Alexa's top 10 million list; today's report includes a year-on-year chart beginning with January 2010, running all the way through 2021. The survey only includes top sites not out of elitism, but as one part of its effort to avoid data-skewing returns from domain-parking services and spammers, which would otherwise dominate legitimate websites through sheer volume. Within that dataset, the story told is clear. Apart from PHP—which held a 72.5 percent share in 2010 and holds a 78.9 percent share as of today—only one other server-side language ever broke a 10 percent share. That one competitor is ASP.NET, which held an impressive 24.4 percent share in 2010 but was down to 9.3 percent in January and 8.3 percent this month. Amongst the small fry, the only truly impressive growth to be seen is in Ruby—which at 5.2 percent this month is still seeing continued uninterrupted growth in W3Techs' survey. This might come as a shock if you're mostly familiar with Ruby on Rails, which itself remains viable but seems to be on the decline in popularity.

  • PHP Holds Impressive Lead Among Server-Side Languages

    This share constitutes an enormous lead over PHP’s rivals, with only one other server-side language ever reaching a 10 percent share. As Jim Salter reports, ASP.NET held a 24 percent share in 2010 but usage has now declined to 8.3 percent.

  • 10 Best Open Source Linux Code Editors [Ed: Very bad list. The first two in the list are Microsoft and even proprietary software with surveillance or 'telemetry' that spies on coders]

    Coding is part of every developer’s life and IDE (Integrated Development Environment) makes this job easier for them. IDEs come with tons of handy features and support programming of various languages within the same environment. Furthermore, IDEs provide users with plug-ins for adding the extra capability to the program and auto-complete tags and classes to make programming faster. Users can also utilize the pre-provided piece of code in their programs. IDEs make coding faster and easier and hence today we’re here to discuss the 10 best Code Editors (IDEs) available for Linux.

Microsoft Exchange Autodiscover protocol found leaking hundreds of thousands of credentials

A flaw in Microsoft's Autodiscover protocol, used to configure Exchange clients like Outlook, can cause user credentials to leak to miscreants in certain circumstances. The upshot is that your Exchange-connected email client may give away your username and password to a stranger, if the flaw is successfully exploited. In a report scheduled to be published on Wednesday, security firm Guardicore said it has identified a design blunder that leaks web requests to Autodiscover domains that are outside the user's domain but within the same top-level domain (TLD). Exchange's Autodiscover protocol, specifically the version based on POX XML, provides a way for client applications to obtain the configuration data necessary to communicate with the Exchange server. It gets invoked, for example, when adding a new Exchange account to Outlook. After a user supplies a name, email address, and password, Outlook tries to use Autodiscover to set up the client.

  • Location history: How your location is tracked and how you can limit sharing it

    In real estate, the age old mantra is “location, location, location,” meaning that location drives value. That’s true even when it comes to data collection in the online world, too — your location history is valuable, authentic information. In all likelihood, you’re leaving a breadcrumb trail of location data every day, but there are a few things you can do to clean that up and keep more of your goings-on to yourself. [...] For some apps, location helps them function better, like navigating with a GPS or following a map. Location history can also be useful for retracing your steps to past places, like finding your way back to that tiny shop in Florence where you picked up beautiful stationery two years ago. On the other hand, marketing companies use location data for marketing and advertising purposes. They can also use location to conduct “geomarketing,” which is targeting you with promotions based on where you are. Near a certain restaurant while you’re out doing errands at midday? You might see an ad for it on your phone just as you’re thinking about lunch. Location can also be used to grant or deny access to certain content. In some parts of the world, content on the internet is “geo-blocked” or geographically-restricted based on your IP address, which is kind of like a mailing address, associated with your online activity. Geo-blocking can happen due to things like copyright restrictions, limited licensing rights or even government control.

  • Chrome 94 Released for Android, macOS, Windows, Linux: What's New | Technology News

    Chrome 94 stable update has been released by Google for Android, iOS, Mac, and Windows operating systems. The update will be rolled out over the coming weeks and it brings new security features, new functionality, and bug fixes. Google Chrome 94 stable is the first version of Chrome of the new four-week release cycle. Previously, Chrome update was released every six weeks. Its features include HTTPS-First mode that makes users browsing more secure. Also, Google said that 19 different security issues were fixed in the Chrome 94 version. The update for Google Chrome was announced through a blog post on September 21. Chrome 94 introduces HTTPS-First mode. It is available in Chrome for desktop systems and for Android. HTTPS is a more secure version of HTTP and many websites support it. With the latest update, the browser will also show a full-page warning when the user loads a site that doesn't support HTTPS. This ensures privacy when using public Wi-Fi. Google says this was previously planned for Chrome 92.

  • Google emits Chrome 94 with 'Idle Detection' API to detect user inactivity amid opposition

    Google has released Chrome 94 for desktop and Android, complete with an "Idle Detection" API to detect user inactivity, despite privacy concerns expressed by Mozilla and Apple. New and changed features in Chrome 94 are listed here and include the removal of the AppCache feature, described as a "security and stability liability", and something which has "imposed a tax on all of Chrome's significant architectural efforts." There is also a new VirtualKeyboard API with more control over its shape and an event fired when it covers page content; more efficient low-level access to media encoders and decoders; and a new JavaScript Self Profiling API which enables developers to collect JavaScript performance profiles from end users.

Kernel: Google, Xen, and Mesa

  • Google Finally Shifting To "Upstream First" Linux Kernel Approach For Android Features

    Google's Android had been notorious for all of its downstream patches carried by the mobile operating system as well as various vendor/device kernel trees while in recent years more of that code has been upstreamed. Google has also been shifting to the Android Generic Kernel Image (GKI) as the basis for all their product kernels to further reduce the fragmentation. Looking ahead, Google is now talking of an "upstream first" approach for pushing new kernel features. Google's Todd Kjos talked today during Linux Plumbers Conference (LPC2021) around their Generic Kernel Image initiative. With Android 12 and their Linux 5.10 based GKI image they have further cut down the fragmentation to the extent that it's "nearly eliminated". With the Android 12 GKI, most of the vendor/OEM kernel features have now either been upstreamed into the Linux kernel, isolated to vendor modules/hooks, or merged into the Android Common Kernel.

  • Clang-format for Xen Coding Style Checking Scheduled - Xen Project

    At the moment there is no tool that would allow to format patches in Xen. The idea of Xen-checker is to use the clang-format approach as a base for Xen ‘checkpatch’ process. The new tool consists of modified .clang-format configuration file to automate Xen patches format checking and reformatting. The tool can be used as a pre-commit hook to check and format every patch automatically. Some features are missing in the clang configurator, so new clang-format options have been proposed for more flexible code formatting. Also, the purpose of the topic is to start the discussion about the existing rules for Xen code formatting to eliminate possible inaccuracies in the work of the Xen checker. This will make it easier to adhere to the unanimous decision.

  • Mesa Merge Pending For Vulkan Ray-Tracing On Older AMD GPUs - Phoronix

    Merged yesterday for Mesa 21.3 was open-source Vulkan ray-tracing for AMD RDNA2 / RX 6000 series GPUs with the RADV driver. Opened today now is a merge request that would provide Vulkan ray-tracing with RADV to pre-RDNA2 GPUs on this driver going back to the likes of Polaris, granted the performance is another story. Joshua Ashton known for his work on DXVK and other Direct3D-on-Vulkan efforts for Valve has opened the merge request to enable RADV Vulkan ray-tracing for older generations of AMD GPUs.
