    Thanks to Alvaro and Martin, guys that belong to Hackspace Peru for the support of the outstanding camp event that will promote the use of FEDORA 23 and GNOME 3.18.

  • Fedora Infrastructure projects in IndiaHacks 2016

    IndiaHacks 2016, HackerEarth’s annual flagship event, aims to be the largest global gathering of developers. The event comprises of a series of hackathons and algorithmic challenges across nine different tracks.

    Open Source is one of the tracks and aims to encourage open source contributions to various participating organizations. The track follows a model similar to Hacktoberfest, where contributions are measured by accepted pull requests and commits to open source software projects.

  • Fedora on non-rooted Android phones - 2016 another update!

    After much trial and error and fighting with permissions, I’ve managed to create a much more simpler way of getting a Fedora 23 chroot running on a non-rooted Android phone.

  • Rebuilding Fedora Under GCC 6 Has Uncovered An Assortment Of Problems

    The past few days Red Hat / Fedora developers have been rebuilding Fedora Rawhide packages with the GCC 6 compiler. Out of the 17,741 packages, 577 packages ran into issues relating to GCC 6 (~3% of the packages).

    Having problems with 577 packages due to the new version of the GNU Compiler Collection is much more than usual with Red Hat's Marek Polacek pointing out last year with the GCC 5 rebuild they had problems with half as many -- 236 problematic packages.

Linux and CPU Security

  • 22 essential security commands for Linux
    There are many aspects to security on Linux systems – from setting up accounts to ensuring that legitimate users have no more privilege than they need to do their jobs. This is look at some of the most essential security commands for day-to-day work on Linux systems.
  • CVE-2018-3639: Spectre Variant 4 Vulnerability Affects the Linux Kernel
    A Spectre variant 4 vulnerability has been identified in the Linux kernel and represents a very dangerous threat to all affected machines. All system administrators are urged to apply the latest updates as soon as possible to mitigate any possible impact.
  • Spectre Number 4, STEP RIGHT UP!
    In the continuing saga of Meltdown and Spectre (tl;dr: G4/7400, G3 and likely earlier 60x PowerPCs don't seem vulnerable at all; G4/7450 and G5 are so far affected by Spectre while Meltdown has not been confirmed, but IBM documentation implies "big" POWER4 and up are vulnerable to both) is now Spectre variant 4. In this variant, the fundamental issue of getting the CPU to speculatively execute code it mistakenly predicts will be executed and observing the effects on cache timing is still present, but here the trick has to do with executing a downstream memory load operation speculatively before other store operations that the load does not depend on. If the CPU is convinced to speculatively execute down this victim path incorrectly, it will revert the stores and the register load when the mispredict is discovered, but the loaded address will remain in the L1 cache and be observable through means similar to those in other Spectre-type attacks.

Mozilla: Framework, WebAssembly, Taskcluster

  • Mozilla uncovers ‘new conceptual framework’ for open source
    A report has been generated which claims to offers ‘a new conceptual framework’ of open source project archetypes. This research cover aspects of open source spanning business objectives, licensing, community standards, component coupling and project governance. It also contains some practical advice on how to use the framework (it actually is a working framework) and on how to set up projects.
  • Qt for WebAssembly – check out the examples!
    WebAssembly is now supported by all major web browsers as a binary format for allowing sand-boxed executable code in web pages that is nearly as fast as native machine code. Qt for WebAssembly makes it possible to run Qt applications on many web browsers without any download steps or special server requirements (other than serving the wasm file). To give you a closer look, we compiled some demos. For best performance, use Firefox.
  • Redeploying Taskcluster: Hosted vs. Shipped Software
    The Taskcluster team’s work on redeployability means switching from a hosted service to a shipped application. A hosted service is one where the authors of the software are also running the main instance of that software. Examples include Github, Facebook, and Mozillians. By contrast, a shipped application is deployed multiple times by people unrelated to the software’s authors. Examples of shipped applications include Gitlab, Joomla, and the Rust toolchain. And, of course, Firefox!

Lenovo Accused of Being Enemy of GNU/Linux (Again)

  • Lenovo denies claims it chose Windows over Linux in second row over technology
    Lenovo Group has angrily denied claims it chose the popular Microsoft Windows system over a domestically-produced Linux operating system (OS) in a recent government procurement programme. The company branded the allegations as “slander” in a statement that follows an internet storm in China in recent weeks over the company’s decisions on domestic versus overseas technology. China’s largest personal computer (PC) maker insisted it had suggested using a domestically-produced Linux OS for both desktop and notebook PCs in a recent PC procurement meeting for suppliers organised by the Central Government Procurement Center, according to the company statement on Tuesday.
  • Lenovo denies on voting against preloading domestic operating systems: report
    Lenovo says the report about it voting against preloading domestic operating systems (O/S) are "deliberate slander," and the company "strongly condemns" the rumor, according to a report by qq.com late Monday. Lenovo claimed the suggestion it made was to use a separately made domestic Linux system solution, including in desktops and notebooks, adding that the advice has been submitted. The company has always supported the development of domestic O/S, Lenovo said. The response came after domestic news site guancha.cn reported earlier the same day that four leading computer manufacturers including Lenovo voted against preloading domestic O/S in personal computers in a poll organized by a government purchasing center on May 16.
