Store passwords with pwsafe

Filed under
Software
HowTos

blogs.techrepublic.com: Secure password storage is a big thing these days, particularly with the (good!) advice of not re-using passwords in more than one place. The thinking behind that is that if someone figures out a password for one service or Web site, they will not be able to re-use that password on other sites and further obtain access to your credentials and services.

Graphics: AMD, RADV, RadeonSI, Mesa 18.0.1

  • AMDGPU DRM Gets "GFXOFF" Patches To Turn Off Graphics Engine
    AMD's Huang Rui has posted a set of 20 patches providing "GFXOFF" support for the AMDGPU Direct Rendering Manager Linux kernel driver. GFXOFF is a new graphics processor feature that allows for powering off the graphics engine when it would otherwise be idle with no graphics workload. Obviously, this would equate to a potentially significant power savings with that engine being able to be shut-off.
  • RADV Driver Lands Support For Vulkan's New Descriptor Indexing Extension
    Earlier this month with the Vulkan 1.1.72 specification update was the new VK_EXT_descriptor_indexing extension that is quickly being well received by developers. The VK_EXT_descriptor_indexing extension allows for creating large descriptor sets made up of all their combined resources and selecting those resources via dynamic indexes in a shader.
  • RadeonSI Now Appears To Support "RX Vega M" With Intel Core CPUs
    One of the most common Linux hardware questions I've received dozens of times in the past few weeks alone has been over the support for "RX Vega M" Vega-based graphics processors found on select newer Intel Kabylake CPUs. It appears RadeonSI at least should now support these Radeon graphics on Intel CPUs.
  • mesa 18.0.1
  • Mesa 18.0.1 Released With A Number Of Fixes
    In addition to Mesa 17.3.9 being released today, Mesa 18.0.1 also rolled out the door as the first point release to last quarter's Mesa 18.0 series. Mesa 18.0.1 features improvements to its Meson build system support, several RADV Vulkan driver fixes, various fixes to the Gallium3D Nine (D3D9) state tracker, various Intel driver fixes, several core Mesa improvements, and then the other random smothering of fixes collected over the past few weeks.

Programming: nGraph Compiler, JavaScript Trademark, PyPI and Pip

  • Intel Opens Up nGraph Source Code For DNN Model Compiler
    Intel tonight announced they are open-sourcing their nGraph compiler code, which serves as a framework-neutral deep neural network model compiler. Intel claims with nGraph and Xeon Scalable hardware that researchers can obtain up to 10x performance improvements over previous TensorFlow integrations, as one example. Besides TensorFlow, nGraph also supports PyTorch, MXNet, Neon, Caffe2, and CNTK while also planning to support other frameworks moving forward.
  • Why it's finally time to give up on the name JavaScript
    An iOS developer has apparently received a cease and desist notice from Oracle over the use of the word "JavaScript" in the title of their app. The developer, Tyanya Software, shared the notice on perennial internet soapbox Reddit to seek advice on how to fight the order. [...] If user reviews are any indication, the app is not even particularly good, with reviewers stating things such as "Not ready for production," "Does not work as advertised," and "Waste of money, don't buy this." The last update to the app was in 2014, which the changelog notes was only an upgrade to add support for iOS 8. The app developer is at least honest about the intent behind the unwieldy name for the app, saying in a Reddit comment that "we game the App Store ranking by adding all the keywords to the app name." While Oracle has a duty to protect their trademarks, this type of legal bludgeoning underscores a historical problem that has been left unaddressed for too long: JavaScript is a terrible name for the thing being described. It has nothing to do with Java, an actual product developed by Sun (now owned by Oracle). JavaScript was developed at Mozilla, and the name was changed during beta releases of Netscape Navigator 2.0 from "LiveScript" to "JavaScript." It has, for some time, caused confusion among casual web users about the difference between Java and JavaScript. Given that ECMAScript is also a trademarked term, it seems best to revert to calling the language "LiveScript" to undercut trademark-related legal posturing. [...] Oracle declined to comment on this story.
  • New PyPI launched
    The new PyPI has been launched. Browser traffic and API calls (including "pip install") have been redirected from the old pypi.python.org to the new site. The old PyPI will shut down on April 30. LWN covered the new PyPI last week.
  • Pip 10.0 has been released
    The release of pip 10.0 has been announced. Some highlights of this release include the removal of Python 2.6 support, limited PEP 518 support (with more to come), a new "pip config" command, and other improvements.

Meltdown/PTI Mitigation Impact On BSDs vs. Linux

Besides the fresh BSD/Linux disk performance tests, some other tests I ran on various BSDs and Linux distributions this week was looking at the performance impact of Intel Meltdown CPU vulnerability mitigation on each of them, namely the performance impact of using kernel page-table isolation. On DragonFlyBSD 5.2, TrueOS 18.03, Ubuntu 16.04, Ubuntu 18.04, and Clear Linux I ran tests when the mitigation was enabled and then again when it was off for seeing the performance impact. Read more

Red Hat and Fedora Leftovers

  • Enterprise Node.js on OpenShift, April 19th, 12 p.m. EDT
    The next online DevNation Live Tech Talk is Thursday, April 19th at 12pm EDT. The topic is “Enterprise Node.js on Red Hat OpenShift” presented by Lance Ball, and hosted by Burr Sutter. The popularity of JavaScript on the front end and the JSON format for data has led to a “JavaScript Everywhere” movement with Node.js at the center. Node.js offers developers an event-driven, non-blocking I/O model that is perfect for high concurrency, low-latency applications that run across distributed devices. Its reactive architecture makes it an ideal technology for containerized microservices architectures you’ve been hearing so much about.

  • Be mindful of jumping into an open source project too soon: RedHat CTO
    Open source software has long been seen as a movement towards collaborative development. In a conversation with BusinessLine, Chris Wright, Vice-President & CTO at RedHat, talks about some of the challenges the open source community is facing and why it is important to set expectations right when it comes to promoting open source software. Edited excerpts:

  • Fedora Community Blog: Fedora meetup at Pune – March 2018

Planning for meetup started 1 month before. Initially Ompragash proposed to have meetup.com account for Fedora Pune to get more awareness. Later dropped this plan, since this is not only Fedora Pune level topic but applicable for all Fedora events.
