Development
  • pocl v1.5 released

    A more detailed changelog here.

    Please note that there's an official pocl maintenance policy in place. This text describes the policy and how you can get your favourite project that uses OpenCL to remain regression free in the future pocl releases.

  • POCL 1.5 Released With Performance Improvements, Fixes For OpenCL On CPUs

    POCL 1.5 has been released as the "Portable CL" implementation for running OpenCL on CPUs and other devices with LLVM back-ends.

    The POCL project lets OpenCL 1.2~2.0 run over CPU back-ends as well as for running OpenCL on NVIDIA GPUs over CUDA, on AMD GPUs via HSA, and other accelerator targets that have LLVM back-end coverage.

  • How to work from home like a pro

    Across the globe, businesses are transitioning to remote work. While remote work or "working from home" has been an overall growing trend, the recent push to transition has been driven by the COVID-19 response; organizations are asking staff to work from home to help limit the spread of the Coronavirus.

    If you are like many of your peers, you may quite suddenly find yourself working from home. How can you remain productive at home when you're used to going into an office?

    A year ago, I launched my own business as a consultant. When I'm not working with a client, I'm working from my home, and during that time, I've learned a thing or two about how to be most effective. I'd like to share a few of those tips here.

  • LLVM Lands Performance-Hitting Mitigation For Intel LVI Vulnerability

    Made public in March was the Load Value Injection (LVI) attack affecting Intel CPUs with SGX capabilities. LVI combines Spectre-style code gadgets with Meltdown-type illegal data flows to bypass existing defenses and allow injecting data into a victim's transient execution. While mitigations on the GNU side quickly landed, the LLVM compiler mitigations were just merged today.

    Intel quickly provided LVI mitigations for the GNU Assembler as new opt-in flags. These assembler mitigations end up introducing many more load fences (LFENCE) to mitigate and cause quite some performance hits but is not enabled by default.

    Intel and other developers in the LLVM community have been working on their respective mitigations for LVI. In fact, a Google engineer proposed a new "SESES" technique for helping address LVI and speculative execution in general. But with Google's own benchmark that only left 7% the original performance (as in down 93%) for the company's BoringSSL workload as their internal fork of OpenSSL.

  • Ada++ Wants To Make The Ada Programming Language More Accessible

    Ada is a beautiful programming language when it comes to code safety with it continuing to be used by aircraft and other safety critical systems. There is now Ada++ as an unofficial fork of the language focused on making the language more accessible and friendlier in an era of the likes of Rust and Golang attracting much interest.

    Ada++ allows for curly braces in place of begin/end keywords, new types like Int_32 / Int_64 / Char_8 / Bool, allow pragmas to be set with a leading # or :, supporting the ++ operator, a raise when construct, and other changes in discussion.

    Ada++ is currently implemented as a forked version of GCC with its Ada front-end being modified but there is talk of a possible LLVM front-end in the future.

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.
