  • Firmware Reverse-Engineering Using NSA Software Continues

    Earlier this month we reported on a new Google Summer of Code project making use of NSA software to help with firmware reverse engineering. So far that effort seems to be paying off of using Ghidra.

    Ghidra is the US National Security Agency's open-source project designed to assist in reverse engineering. Ghidra is similar to IDA Pro and other decompilers/disassemblers. The focus of the GSoC 2019 project has been integrating the support to make it suitable as a tool to help with firmware reverse-engineering.

  • Application lifecycle management for container-native development

    Ultimately, developers are expensive, but they are the domain experts in what they build. With development teams often being treated as product teams (who own the entire lifecycle and support of their applications), it becomes imperative that they control the end-to-end process on which they rely to deliver their applications into production. This means decentralizing both the ALM process and the tooling that supports that process. In this article, we’ll explore this approach and look at a couple of implementation scenarios.

  • Teaching algorithmic ethics requires an open approach

    his trend could have profoundly positive impacts on humanity. Consider, for example, the ways in which AI applications have already proven revolutionary in medical diagnosis. But with and alongside the benefits these systems promise are also serious risks, for the growing unchecked use of algorithms in this fashion risks dangerously amplifying inequality and concentrating power in the hands of the few. Other related problems may accompany this, such as the increased commodification of personal information absent consumer protections, or the buildout of digital surveillance infrastructures that are more often than not turned against already marginalized or oppressed populations.

    One of the most promising mechanisms for combating the dangerous encroachment of individual agency and power through algorithms is open education. Policymakers and advisors educated on these ethical technology issues can make informed regulatory decisions, technologists can increase their awareness of the impacts of their designs, and citizens and consumers can adequately understand how algorithmic systems are impacting their everyday lives. Where knowledge is power, education can provide that knowledge.

  • OOP Method Types in Python: @classmethod vs @staticmethod vs Instance Methods
  • Multiple Linear Regression with Python
  • Testing Complex Systems with Maintainable Test Suites
  • Kubernetes Operators Best Practices

    Kubernetes Operators are processes connecting to the master API and watching for events, typically on a limited number of resource types.

    When a relevant event occurs, the operator reacts and performs a specific action. This may be limited to interacting with the master API only, but will often involve performing some action on some other systems (this could be either in cluster or off cluster resources).

Kernel: Systemd, DXVK, Intel and AMD

  • Systemd Is Now Seeing Continuous Fuzzing By Fuzzit
    In hoping to catch more bugs quickly, systemd now has continuous fuzzing integration via the new "Fuzzit" platform that provides continuous fuzzing as a service.  New this week to systemd is the continuous fuzzing integration where every pull request / push will see some quick checks carried out while on a daily basis will be fuzzed in full for all targets.

  • DXVK 1.2.2 Brings Minor CPU Overhead Optimizations, Game Fixes
    In time for those planning to spend some time this weekend gaming, DXVK lead developer Philip Rebohle announced the release of DXVK 1.2.2 that will hopefully soon be integrated as part of a Proton update for Steam Play but right now can be built from source. While certain upstream Wine developers express DXVK being a "dead end" and are optimistic in favor of piping their WineD3D implementation over Vulkan, for Linux gamers today wanting to enjoy D3D11 Windows games on Linux the DXVK library continues working out splendid with great performance and running many Direct3D games with much better performance over the current WineD3D OpenGL code.
  • Intel 19.23.13131 OpenCL NEO Stack Adds Comet Lake Support
    We've seen the Intel Comet Lake support get pieced together in recent months in the different components making up the Intel Linux graphics stack while the compute-runtime is the latest addition. Comet Lake as a refresher is a planned successor to Coffeelake/Whiskeylake and expected to come out this year as yet more 9th Gen hardware. But Comet Lake should be interesting with rumored 10-core designs. Though with being more processors with Gen9 graphics, the Comet Lake Linux support basically boils down to adding in the new PCI IDs.
  • AMD Wires Its New Runtime Linker Into RadeonSI Gallium3D
    RadeonSI Gallium3D has already shifted over to using this new linker. Making use of the .rodata should help with efficiencies throughout the driver (more details in this forum thread) but at this point is mostly laying the groundwork for more improvements to be made moving forward.

Red Hat and Fedora Leftovers

  • Building IT Transformation Architecture with Red Hat OpenShift
    In the era of mobile applications, business challenges to the enterprise IT organizations are more dynamic than ever. Many enterprises have difficulties responding in time because of the inherent complexity and risk of integrating emerging technologies into existing IT architectures. In this article, I will share my experience on how to utilize Red Hat OpenShift as a “Middle Platform” (中台) for enterprises to construct its bimodal IT architecture with agile, scalable and open strategy. In the past year, I have discussed with many corporate customers–especially in the financial services industry–the challenges of digital transformation, and the solutions. Most of their difficulties are coming from “core systems” which have been working for more than 10 years.
  • Fedora Community Blog: FPgM report: 2019-24
    Here’s your report of what has happened in Fedora Program Management this week. Elections voting is open through 23:59 UTC on Thursday 20 June. I have weekly office hours in #fedora-meeting-1. Drop by if you have any questions or comments about the schedule, Changes, elections, or anything else.
  • Copr's Dist-Git
    In Copr, we use dist-git to store sources as well. However, our use case is different. In the past, Copr only allowed to build from URL. You provided a URL to your SRC.RPM and Copr downloaded it and built it. This was a problem when the user wanted to resubmit the build. The original URL very often did not exists anymore. Therefore we came with an idea to store the SRC.RPM somewhere. And obviously, the dist-git was the first idea.

Software: FreeFileSync, Debian/GSOC, LibreOffice and Lightworks

  • File Synchronization App FreeFileSync Brings Another Update
    File synchronization software, FreeFileSync releases latest update with 10.13. FreeFileSync is a folder and file synchronization free software that is available for Linux, Windows and Mac. This software can sync between your devices files and folders and only sync the changed files/directories. That means it can identify the changed files and make sure to transfer those in backup systems. Armed with scheduling of transfers, JOB features for sync – this free and open source software is one of the best file sync/ backup software available today. FreeFileSync released 10.13 with bunch of big fixes and enhancements.
  • Utkarsh Gupta: GSoC Bi-Weekly Report - Week 1 and 2
    The idea is to package all the dependencies of Loomio and get Loomio easily installable on the Debian machines. The phase 1, that is, the first 4 weeks, were planned to package the Ruby and the Node dependencies. When I started off, I hit an obstacle. Little did we know about how to go about packaging complex applications like that. I have been helping out in packages like gitlab, diaspora, et al. And towards the end of the last week, we learned that loomio needs to be done like diaspora.
  • Annual Report 2018: LibreOffice Conference
    The LibreOffice Conference is the annual gathering of the community, our end-users, and everyone interested in free office software. Every year, it takes place in a different country and is supported by members of the LibreOffice commercial ecosystem. In 2018, the conference was organized by the young and dynamic Albanian community at Oficina in Tirana, from Wednesday, September 26, to Friday, September 28, the eight anniversary of the LibreOffice project. Here’s a quick video recap – read on for more details…
  • New Lightworks Beta Version 14.6 revision 114986 Now Available on Windows Linux and Mac!
    It is strongly recommended that users backup their project folder before installing any new Beta build of Lightworks. We are pleased to announce the second Beta of Lightworks 14.6 which includes many changes based on Forum feedback. Excellent work all round and we are hopeful that this Beta Cycle will be short lived. We hope you enjoy all the features and changes in the latest version which can be found in the : Changelog pages
  • Lightworks 14.6 Remains A Closed-Up Blob, But At Least The Linux Support Continues
    It was nearly a decade ago the high-end, commercial video software editing solution Lightworks announced they would be going open-source but to this day that milestone has yet to be materialized. Lightworks though does continue advancing with their v14.6 release on the horizon and at least their added Linux support continues to be expanded upon. EditShare, the company behind Lightworks, really dropped the ball when it came to their open-source plans. All that we've been able to gather over these years is that they hit some complexities with their original open-source plans and aren't committed enough in seeking to work through those issues to make the code public. So at the end of the day Lightworks is still a closed-source non-linear video editor, but at least it's one of the most feature-rich/professional-grade solutions with native Linux support.
