  • 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).

Leftovers: IBM, Mozilla and SUSE

  • What Is Razee, and Why IBM Open Sourced It
    The continuous delivery software that's been doing the heavy lifting on IBM's global Kubernetes platform is now open source.
  • View Source 5 comes to Amsterdam
    Mozilla’s View Source Conference is back for a fifth year, this time in Amsterdam, September 30 – October 1, 2019. Tickets are available now.
  • SUSE & SAP “A 20 years of Partnership”
  • SUSE on the IO500 List for HPC Storage
    If you haven’t been hanging around the Ceph world for a bit, you may not realize that Ceph was originally intended to provide a distributed file-system to service HPC clusters.  While this was the original intent, Ceph has taken a round-a-bout path to relevance in this space, especially given that we are only supporting multiple active MDS servers since the Luminous release.  The result is that we are, only now, really starting to see adoption in the HPC space, and mostly for the second tier storage needs. Enter, the science project.  Given an all-flash environment on SATA SSDS with a fast storage pool on Intel Optane for the metadata, would it be possible to provide a reasonable storage environment for HPC clusters?

GAFAM and 'Cloud': Google, Microsoft, Amazon and GitHub

  • Daniel Stenberg: Google to reimplement curl in libcrurl
    By throwing a lot of man power on it. As the primary author and developer of the libcurl API and the libcurl code, I assume that Cronet works quite differently than libcurl so there’s going to be quite a lot of wrestling of data and code flow to make this API work on that code. The libcurl API is also very versatile and is an API that has developed over a period of almost 20 years so there’s a lot of functionality, a lot of options and a lot of subtle behavior that may or may not be easy or straight forward to mimic. The initial commit imported the headers and examples from the curl 7.65.1 release.
  • Microsoft, you should look away now: Google's cloud second only to AWS in dev survey [Ed: Longtime Microsoft booster Tim Anderson  on Azure being a failure after so many entryism attempts and underhanded tactics]
    Coders use Google Cloud Platform (GCP) more than Microsoft Azure, though Amazon Web Services (AWS) has a comfortable lead, according to a Developer Ecosystem survey conducted by tools vendor JetBrains. Developer usage is 67 per cent AWS versus 28 per cent GCP and 21 per cent Azure, according to the new survey. Unfortunately, the question was posed in a different way in the 2018 survey, adding on-premises into the mix, but last year Azure and GCP had equal share after AWS. The survey had 19,000 participants invited via "Twitter ads, Facebook ads, Google Adwords and JetBrains' own communication channels," the tools vendor said, though "only the responses of 6,993 respondents were included in the report." Responses were removed to reduce bias, yet it warned "some bias may be present as JetBrains users may have been more willing on average to compete the survey".
  • Get your coat, you've pulled a Pull Panda: GitHub goes home with code collab specialists [Ed: Notice how Microsoft only takes GitHub in more of a proprietary software direction. That says a lot – they have plans and they’re really detrimental to FOSS]

Kernel: Linux Changes, Certifications, Graphics, PCI Express 6.0 and Bug

  • PowerCap/RAPL Code To Support Icelake Desktop / X / Xeon D With Linux 5.3
    While as of Linux 5.2 the support for Intel's Icelake CPUs appear production ready with all of the bits in place from new IDs to the much enhanced "Gen 11" graphics, there are a few stragglers of items to land with the upcoming Linux 5.3 merge window though could be back-ported to current series. Fortunately, we haven't found anything major to be missing. One of the latest bits of Icelake Linux support is handling of these next-generation processors within the PowerCap / RAPL (Running Average Power Limit) driver code. In particular, the desktop/workstation Icelake parts. This is the code for reading the estimated CPU package power consumption based on hardware performance counters and the ability to artificially limit the power draw of the processor via software.

  • AMD Navi GPU stack bares all in Linux graphics driver update
    Eight Navi GPU variants have been spotted in Linux driver code. AMD’s next-gen RDNA graphics chips are set for launch on July 7, 2019 within the RX 5700 XT and RX 5700, but the red team has plenty of silicon in store for a range of applications. Including console, laptops, desktop, and mobile phones. The GPU codenames were spotted within Linux display drivers after the additional code was submitted and signed off by two AMD employees. The code adds support for Display Core Next, or DCN2, which “is the display block for Navi10.” Each entry following adds the necessary ASIC IDs for each Navi chip in the stack, starting with Navi 10 and down to Navi 21 LITE.
  • Nouveau Driver Picking Up NVIDIA TU116 GPU Support For Linux 5.3
    Building off the initial Turing mode-setting bits that were in place since Linux 5.0 and have continued stepping along to support newer variants on successive kernel releases, the Linux 5.3 kernel is slated to add support for the TU116 graphics processor.
