  • OpenBLAS 0.3.11 Brings Many Changes From Zen 3 To POWER10 Support - Phoronix

    OpenBLAS 0.3.11 is out as the newest major feature release for this BLAS linear algebra library. While the version number may not make it seem like a big update, it is especially when it comes to new CPU support.

    When it comes to new processor support there is now optimized support for POWER10, Intel Cooper Lake Xeon support, auto-detection for Intel Comet Lake, auto-detection for AMD Renoir / Matisse / Zen 3 processors, preliminary support for Apple Vortex ARM processors, support for Cavium ThunderX3T110, and improved support for IBM Z14.

  • Dirk Eddelbuettel: digest 0.6.26: Blake3 and Tuning

    And a new version of digest is now on CRAN will go to Debian shortly.

    digest creates hash digests of arbitrary R objects (using the md5, sha-1, sha-256, sha-512, crc32, xxhash32, xxhash64, murmur32, spookyhash, and blake3 algorithms) permitting easy comparison of R language objects. It is a fairly widely-used package (currently listed at 896k monthly downloads, 279 direct reverse dependencies and 8057 indirect reverse dependencies, or just under half of CRAN) as many tasks may involve caching of objects for which it provides convenient general-purpose hash key generation.

  • Javascript Regular Expression – Linux Hint

    Many programmers are familiar with the notion that the regular expression is a useful yet underrated concept. But, they do not know very well how to use regular expressions efficiently. Regular expressions are used in not only Javascript but almost all other programming languages. In this article, you will learn about regular expressions step by step. It should be easy for programmers of any level to understand the concepts covered in this article.

  • Javascript toLowerCase Function – Linux Hint

    Javascript is a popular scripting or programming language. Programmers often use Javascript to manipulate or manage data. For example, say, you are getting some data from a user in the fields of an HTML form. While getting the data from the user, you cannot control what the user is typing. But, you also need to show the data in a good format. Users may input capital letters where they are not needed or vice versa. While saving data to the database or showing data to a web page, as a programmer, it is necessary to take care of this function. For this purpose, we have Javascript’s built-in function toLowerCase() for converting a string to lower-case letters.

  • Javascript String Length – Linux Hint

    Javascript is a scripting or programming language that is quickly becoming one of the most widely used programming languages in the world. Strings are a crucial part of all programming languages. Programmers often need to use strings to manipulate or manage data. Javascript’s built-in functions or properties for manipulating strings can come in handy. For example, if you are getting some user data in form fields in HTML and you want to restrict the length of a string while showing some data on a webpage, Javascript’s built-in string length property can help you in this case. This article shows you what the string length property in Javascript is and how you can use it in a few different scenarios.

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.
