  • Niko Matsakis: Async Vision Doc Writing Sessions IV

    Next week, we will be holding more vision doc writing sessions. We are now going to expand the scope to go beyond “status quo” stories and cover “shiny future” stories as well. Keep your eyes peeled for a post on the Rust blog and further updates!

  • Google Online Security Blog: Rust in the Android platform

    Correctness of code in the Android platform is a top priority for the security, stability, and quality of each Android release. Memory safety bugs in C and C++ continue to be the most-difficult-to-address source of incorrectness. We invest a great deal of effort and resources into detecting, fixing, and mitigating this class of bugs, and these efforts are effective in preventing a large number of bugs from making it into Android releases. Yet in spite of these efforts, memory safety bugs continue to be a top contributor of stability issues, and consistently represent ~70% of Android’s high severity security vulnerabilities.

  • Google Begins Allowing Rust Code For Developing Android - Phoronix

    Not only is the Linux kernel moving to allow Rust code to be optionally used within the kernel, but Google is now allowing Rust code to be used for system programming work on Android's low-level operating system components too.

    Google announced on Tuesday by way of their security blog that they are now allowing Rust to be used for Android platform system code. Rust will be allowed in the Android Open-Source Project for "developing the OS itself" given its emphasis on memory-safety and security.

  • Learn Scikit-learn and Perform Machine Learning with Python

    Scikit-learn is one of the most popular machine leaning libraries for Python. It provides many unsupervised and supervised learning algorithms that make machine leaning simpler.

  • IBM creates a COBOL compiler – for Linux on x86 • The Register

    IBM has announced a COBOL compiler for Linux on x86.

    News of the offering appeared in an announcement that states: "IBM COBOL for Linux on x86 1.1 brings IBM's COBOL compilation technologies and capabilities to the Linux on x86 environment," and describes it as "the latest addition to the IBM COBOL compiler family, which includes Enterprise COBOL for z/OS and COBOL for AIX."

    COBOL – the common business-oriented language – has its roots in the 1950s and is synonymous with the mainframe age and difficulties paying down technical debt accrued since a bygone era of computing.

    So why is IBM – which is today obsessed with hybrid clouds – bothering to offer a COBOL compiler for Linux on x86?

    Because IBM thinks you may want your COBOL apps in a hybrid cloud, albeit the kind of hybrid IBM fancies, which can mean a mix of z/OS, AIX, mainframes, POWER systems and actual public clouds.

  • Ryan Kavanagh: Writing BASIC-8 on the TSS/8

    I recently discovered SDF’s PiDP-8. You can access it over SSH and watch the blinkenlights over its twitch stream. It runs TSS/8, a time-sharing operating system written in 1967 by Adrian van de Goor while a grad student here at CMU. I’ve been having fun tinkering with it, and I just wrote my first BASIC program1 since high school. It plots the graph of some user-specified univariate function. I don’t claim that it’s elegant or well-engineered, but it works!

  • Signal/Slot Connection Throttlers

    Today, we’ll talk about ways to throttle your signal/slots connections — in other words, how to activate a slot less often than the emission rate of the signal it’s connected to. The usual reason why you may want something like this is performance. Invoking a slot at a high frequency may be too expensive for your application, so you need to rate-limit the slot’s activation.

  • Deploy Quarkus everywhere with Red Hat Enterprise Linux (RHEL)

    Java is one of the most popular programming languages in the world. It has been among the top three languages used over the past two decades. Java powers millions of applications across many verticals and platforms. Linux is widely deployed in data centers, edge networks, and the cloud.

    Today we announced that Quarkus is now available for all Red Hat Enterprise Linux (RHEL) customers. If you are running RHEL, you can easily use the Red Hat build of Quarkus in your Java applications. If you are developing applications on a Kubernetes platform like Red Hat OpenShift, you can also use the Red Hat build of Quarkus as of November 2020.

    What is Quarkus, and how can you develop and deploy it on Red Hat Enterprise Linux? Read on to learn more.

  • What’s new with Quarkus? And other updates in Red Hat Runtimes

    As we round out the first quarter of 2021, we wanted to share the latest updates to the Red Hat Runtimes portfolio. As always, our team is working hard to bring customers the latest best-in-class innovations and updates to help make developers’ jobs a bit easier. Let’s get right to it.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
