  • Fedora Looks To Introduce The Storage Instantiation Daemon

    As one of the last minute change proposals for Fedora 33 is to introduce the Red Hat backed Storage Instantiation Daemon "SID" though at least for this first release would be off by default. The Storage Instantiation Daemon is one of the latest storage efforts being worked on by Red Hat engineers.

    The Storage Instantiation Daemon is intended to help manage Linux storage device state tracking atop udev and reacts to changes via uevents. This daemon can offer an API for various device subsystems and provides insight into the Linux storage stack. More details on this newer open-source effort via sid-project.github.io.

  • Explore best practices for Spark performance optimization

    I am a senior software engineer working with IBM’s CODAIT team. We work on open source projects and advocacy activities. I have been working on open source Apache Spark, focused on Spark SQL. I have also been involved with helping customers and clients with optimizing their Spark applications. Apache Spark is a distributed open source computing framework that can be used for large-scale analytic computations. In this blog, I want to share some performance optimization guidelines when programming with Spark. The assumption is that you have some understanding of writing Spark applications. These are guidelines to be aware of when developing Spark applications.

    [...]

    Spark has a number of built-in user-defined functions (UDFs) available. For performance, check to see if you can use one of the built-in functions since they are good for performance. Custom UDFs in the Scala API are more performant than Python UDFs. If you have to use the Python API, use the newly introduced pandas UDF in Python that was released in Spark 2.3. The pandas UDF (vectorized UDFs) support in Spark has significant performance improvements as opposed to writing a custom Python UDF. Get more information about writing a pandas UDF.

  • The Talospace Project: Firefox 78 on POWER

    Firefox 78 is released and is running on this Talos II. This version in particular features an updated RegExp engine but is most notable (notorious) for disabling TLS 1.0/1.1 by default (only 1.2/1.3). Unfortunately, because of craziness at $DAYJOB and the lack of a build waterfall or some sort of continuous integration for ppc64le, a build failure slipped through into release but fortunately only in the (optional) tests. The fix is trivial, another compilation bug in the profiler that periodically plagues unsupported platforms, and I have pushed it upstream in bug 1649653. You can either apply that bug to your tree or add ac_add_options --disable-tests to your .mozconfig. Speaking of, as usual, the .mozconfigs we use for debug and optimized builds have been stable since Firefox 67.

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.
