  • AMDGPU Gets Some Promising Fixes For Linux 5.4: Clang, Undervolting, Golden Settings

    - Updates for building the AMDGPU driver under LLVM Clang. With LLVM Clang 9.0 and Linux 5.3+ the kernel can build with mainline code-bases of each (finally Clang'ing the x86_64 mainline Linux kernel!), but AMDGPU has been one of the problematic modules running into issues. A few fixes to AMDGPU now should have it working properly with Clang.

  • CPython Core Developer Sprint 2019

    During the week of September 9th to September 13th, 34 core CPython committers gathered together in the Bloomberg London headquarters for the 2019 Python core developer sprint. The core developer sprint is an annual week-long meeting in which the CPython core team has the opportunity to meet each other in person in order to work together free from distractions. Having this many core developers in the same room allows us to work efficiently on several aspects of the Python language and CPython (the default implementation). This can include topics such as future designs and in-process PEPs (Python Enhancement Proposals), prototyping exciting changes that we may see in the future, various core development processes such as issue triaging and pull request reviewing, and much more! This is a very exhausting week for everyone, but also a very productive one, as these meetings are known for generating a much-needed boost in core development, especially close to new releases.

  • Python REST APIs With Flask, Connexion, and SQLAlchemy – Part 4

    In Part 3 of this series, you added relationships to the REST API and to the database that supports it. This gave you a powerful tool you can use to build interesting programs that send persistent data, as well as the relationships between that data, to a database system. Having a REST API gives you the ability to create a Single-Page Application (SPA) with HTML, CSS, and JavaScript. This is a good starting point before you make the jump to more powerful front-end frameworks, like Angular or React.

  • Python Write File/ Read File

    This tutorial covers the following topic – Python Write File/Read File. It describes the syntax of the writing to a file in Python. Also, it explains how to write to a text file and provides several examples for help.

    For writing to a file in Python, you would need a couple of functions such as Open(), Write(), and Read(). All these are built-in Python functions and don’t require a module to import.

NetRunner | Review from an openSUSE User

Filed under

NetRunner (19.08) is not one of those distributions I hear touting its uniqueness and wonders loudly on the Internet. As part of a two week challenge for BigDaddyLinux Live, I lassoed an ISO and took it for a spin on a VM. Some may argue that a VM doesn’t make for a good test experience and I would agree to that, sort of… This is not going to be a test of NetRunner’s performance on bare metal but rather, this is an impression of how the developers are answering the operating system question.

Bottom Line Up Front, NetRunner has a look of its own. The default software is refreshingly not minimal as that seems to be the talk of many Linux enthusiasts (I blame Arch for that). The included pieces of software makes for a great showcase of the various KDE applications. Personally, this is a good approach for most users. Those minimal installation folks should just learn to remove software using the package manager if that is such a huge issue. I am not keen on the default theme with the red cursor and the lack of a usable Dark NetRunner theme. Aside from that, it appears to be a good KDE Plasma experience and a fine showcase of the various applications a Linux user should try. This is my biased review of NetRunner as an openSUSE user.

Linus Torvalds: "Git proved I could be more than a one-hit wonder."

Filed under

Recently some neighbor kids asked me what I do for a living. "I read and write emails," I told them. They weren't very impressed.

However, they'd likely be a bit more impressed had they heard the same thing come from the mouth of Linus Torvalds, founder of the Linux operating system. In a fireside chat at the Open Source Summit Europe, Torvalds was asked how he spends his time as the kernel maintainer. "I read email," was Torvalds' reply. But not just any email. The email Torvalds answers helps to keep over 25 million lines of code humming for the hundreds of millions of Linux-powered devices worldwide. So it kind of matters if he replies.

  • Arduino Nano Floppy Emulator For When Your Disk Is Not Accessible | Hackaday

    Among the plethora of obsolete removable media there are some which are lamented, but it can be difficult to find those who regret the passing of the floppy disk. These flexible magnetic disks in hard plastic covers were a staple of computing until some time in the early 2000s, and their drives could be found by the crateload in any spares box. But what about today, when there’s a need for a real floppy drive and none is to be found? Enter [Acemi Elektronikci], with an Arduino Nano based floppy emulator, that plugs into the floppy port of a PC old enough to have one, and allows the easy use of virtual floppy disks.

  • Sensitive information detection using the NVIDIA Morpheus AI framework

    The growth of cloud-native applications has driven an explosion of east-west network traffic within a datacenter where applications can create hundreds of thousands of network connections among virtual machines and containers. As a consequence, the ability to track, monitor, and secure a datacenter in a timely manner has risen above that of any individual or team, thus requiring the help of AI and machine learning (AI/ML) to enable ITOps, infrastructure security, and DevSecOps teams to manage the complexity of modern cloud-native applications and the underlying platforms. Red Hat and NVIDIA have been working together to bring the security analytics capabilities of the NVIDIA Morpheus AI application framework to Red Hat infrastructure platforms for cybersecurity developers. This article provides a set of configuration instructions to Red Hat developers working on applications that use the NVIDIA Morpheus AI application framework and NVIDIA BlueField data processing units (DPUs) to secure interservice communication.

  • How Podman runs on Macs and other container FAQs | Enable Sysadmin

    As the Podman machine function becomes more used—particularly on Macs—there have been many questions about how this all works. Some of what is tossed around on the internet is pure speculation, so this article aims to eliminate any speculation. Many people do not realize that containers are really Linux. As such, Linux containers cannot run natively on macOS. Therefore, the containers must run in a Linux virtual machine (VM), and a Podman client interacts with that VM. This is in line with all solutions for running containers on macOS.
