  • POCL 1.3 Released For OpenCL On CPUs As The Portable Computing Language

    Just days after the most recent POCL 1.3 release candidate, the Portable Computing Language 1.3 release is now officially available for an open-source project allowing OpenCL kernels to be executed on CPUs.

    POCL 1.3 implements OpenCL 1.2 with some CL 2.0 functionality and is a portable OpenCL implementation for running on CPUs or there is also some offloading capabilities to NVIDIA GPUs via CUDA or AMD GPUs via HSA.

  • NEC Is Looking To Contribute SX-Aurora VE Accelerator Support To LLVM

    The newest compiler back-end proposed for merging into the LLVM compiler code-base is for the NEC SX-Aurora VE (Vector Engine) accelerator card.

    NEC launched the SX-Aurora a year ago as a "Vector Engine" PCI Express accelerator card supporting up to eight of these vector processors per server. The NEC SX-Aurora features eight cores clocked up to 1.6GHz and six HBM2 memory modules on a silicon interposer. The CPU double precision performance is rated up to 2.45 TFLOPS based upon the model or 4.9 single-precision TFLOPS. The six HBM2 stacks yield up to 48GB of working memory at 1.2TB/s memory bandwidth.

  • Test and Code: 71: The Ultimate Guide To Memorable Tech Talks - Nina Zackarenko

    Nina Zakharenko gives some great advice about giving tech talks.
    We talk about a blog series that Nina wrote called "The Ultimate Guide To Memorable Tech Talks". Of course, we don't rehash the whole blog series, but this episode is full of great help and encouragement for your own public speaking adventures.

  • Alexander Todorov: The Art of [Unit] Testing

    A month ago I held a private discussional workshop for a friend's company in Sofia. With people at executive positions on the tech & business side we discussed some of their current problems with respect to delivering a quality product. Additionally I had a list of pre-compiled questions from members of the technical team, young developers, mostly without formal background in software testing! Some of the answers were inspired by The Art of Unit Testing by Roy Osherove hence the title!

  • An RPython JIT for LPegs

    The following is a guest post by Stefan Troost, he describes the work he did in his bachelor thesis:

    In this project we have used the RPython infrastructure to generate an RPython JIT for a less-typical use-case: string pattern matching. The work in this project is based on Parsing Expression Grammars and LPeg, an implementation of PEGs designed to be used in Lua. In this post I will showcase some of the work that went into this project, explain PEGs in general and LPeg in particular, and show some benchmarking results.

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.
