  • Only a Few Days Left to Cast Your Ballot in the Board Elections

    With only a few days left to go in the Board Elections, openSUSE enthusiast Ahmad Romadhon would like to urge all openSUSE Members who have not yet voted to cast their ballots before voting closes Friday, February 15, 2019 at 12h00 UTC.

    The Gajah Mada University Indonesian Literature student from Yogyakarta, Indonesia, has contributed a new Poster for the openSUSE Elections with this goal in mind, as a healthy Community depends entirely on the active participation of its Members.

    The ballots were sent out last week for the voting process to choose three Board Members in the 2018-2019 openSUSE Board Elections from a total of seven top quality Candidates in the running.

  • Why Apple is Patenting Swift Features, Even Though It’s Open Source

    Many think of ‘open source’ the same way they do free software: totally free and open for everyone to use. And Swift is indeed open and free. Released under the Apache license, Swift is also gaining LSP support, which will give it the ability to compile in just about any IDE you’d want to use (and even some you don’t).

    Apple still drives Swift’s progress. Swift.org, the site dedicated to Swift’s open-source roadmap and release history, is owned and managed by Apple. Those who contribute most to the language’s success are typically Apple staffers, or were (Swift creator Chris Lattner, who is now at Google, is still heavily involved with the language).

Graphics: TuxClocker and VK_EXT_depth_clip_enable

  • TuxClocker: Another GPU Overclocking GUI For Linux
    Adding to the list of third-party GPU overclocking utilities for Linux is TuxClocker, a Qt5-based user-interface currently with support for NVIDIA graphics cards and experimental support for AMD GPUs.  TuxClocker is a Qt5 overclocking tool that supports adjusting not only the memory/core frequencies but also the power limit, fan speed, and other tunables based upon the GPU/driver in use. There is also graph monitors to show the power and temperature limit, where supported, among other features.  TuxClocker offers similar functionality to other third-party, open-source Linux GPU overclocking software though where as most utilities focus just on NVIDIA or AMD hardware, TuxClocker is pursuing both. Currently their stable release supports just NVIDIA GPUs but the development code has AMD Radeon support in the works.
  • Intel Wires VK_EXT_depth_clip_enable Into Their Vulkan Driver, Helping DXVK
    Intel's open-source ANV Vulkan driver now supports the VK_EXT_depth_clip_enable that was designed in part to help the DXVK project for mapping Direct3D atop of the Vulkan API.

Programming Leftovers

  • Packaging PyQt5 apps with fbs
    fbs is a cross-platform PyQt5 packaging system which supports building desktop applications for Windows, Mac and Linux (Ubuntu, Fedora and Arch). Built on top of PyInstaller it wraps some of the rough edges and defines a standard project structure which allows the build process to be entirely automated. The included resource API is particularly useful, simplifying the handling of external data files, images or third-party libraries — a common pain point when bundling apps.
  • Infrastructure monitoring: Defense against surprise downtime
    There are a number of tools available that can build a viable and strong monitoring system. The only decision to make is which to use; your answer lies in what you want to achieve with monitoring as well as various financial and business factors you must consider. While some monitoring tools are proprietary, many open source tools, either unmanaged or community-managed software, will do the job even better than the closed source options. In this article, I will focus on open source tools and how to use them to create a strong monitoring architecture.
  • GSlice considerations and possible improvements
    The paper Mesh: Compacting Memory Management for C/C++ Applications is about moving memory allocations for compaction, even though the memory pointers are exposed. The idea is to merge allocation blocks from different pages that are not overlapping at page offsets, and then letting multiple virtual page pointers point to the same physical page. Some have asked about the applicability to the GSlice allocator.

Security Leftovers

  • Wi-Fi ‘Hiding’ Inside USB Cable: A New Security Threat On The Rise?
    Today, the world has become heavily reliant on computers owing to the various advantages they offer. It has thus become imperative that we, as users, remain updated about the various threats that can compromise the security of our data and privacy. A recent report published by Hackaday details a new threat that might just compromise the integrity of devices. At first glance, the O.MG cable (Offensive MG Kit) looks like any other USB cable available in the market. It is what lurks within that is a cause for concern.

  • The Insights into Linux Security You May Be Surprised About
    Linux has a strong reputation for being the most secure operating system on the market. It’s been like that for many years, and it doesn’t seem like Windows or macOS are going to overtake it anytime soon. And while the operating system’s reputation is well-deserved, it can also be harmless experienced users. The problem is that some seem to put too much trust in the capabilities of Linux by default. As a result, they often don’t pay enough attention to the manual aspect of their security. Linux can help you automate your workflow to a large extent, but it still requires a manual touch to keep things going well. This is even truer when it comes to security.
  • One Identity Bolsters Unix Security with New Release of Authentication Services
    Unix systems (including Linux and Mac OS), by their very nature, have distinct challenges when it comes to security and administration. Because native Unix-based systems are not linked to one another, each server or OS instance requires its own source of authentication and authorization.
  • Book Review – Linux Basics for Hackers
    With countless job openings and growth with no end in sight, InfoSec is the place to be. Many pose the question, “Where do I start?” Over his years of training hackers and eventual security experts across a wide array of industries and occupations, the author ascertains that one of the biggest hurdles that many up-and-coming professional hackers face is the lack of a foundational knowledge or experience with Linux. In an effort to help new practitioners grow, he made the decision to pen a basic ‘How To’ manual, of sorts, to introduce foundational concepts, commands and tricks in order to provide instruction to ease their transition into the world of Linux. Out of this effort, “Linux Basics for Hackers” was born.
