  • Intel 13th Gen Raptor Lake CPUs get further support in latest Linux kernel

    Intel's Raptor Lake processors will utilize a next-gen Raptor Cove core configuration and deliver as many as 24 cores and 32 threads. Initially, the 13th gen Intel CPUs will offer 8 Raptor Cove and 16 Gracemont Enhanced cores for the highest SKU accessing a sum of 32 threads. In total, the new Intel family will offer 36 MB of L3 cache for all bodies and 18 MB of L2 cache, reaching a total of 54 MB of Smart Cache for the premium Raptor Core chipset.

    Intel is estimated to feature 2 MB L2 / 3 MB L3 cache per Raptor Cove core while each Gracemont Cluster will showcase 4 MB L2 and 3 MB L3 cache — a total of 36 MB L3 cache across all cores, 16 MB (2x8) P-cores, and 16 MB (4x4) E-cores. The 125W Intel Raptor Lake-S variant will offer a PL1 rating of 125W, PL2 rating of 188W, and PL4 rating of 238W. In performance modes, Raptor Lake is rumored to provide between 125W to as high as 314W.

  • Linux devs fix nasty vulnerability dating back half a decade | TechRadar

    An exploitable bug sitting in a popular Linux kernel module, has been found after five years, researchers have claimed.

    Detailing the findings in a blog post, researcher Samuel Page from cybersecurity firm Appgate said the flaw was a stack buffer overflow, found in the kernel networking module for the Transparent Inter-Process Communication (TIPC) protocol.

    Page describes TIPC as an IPC mechanism designed for intra-cluster communication. “Cluster topology is managed around the concept of nodes and the links between these nodes,” he says.

  • Sorting beads the easy way | Arduino Blog

    If you want to measure the blueness of an object, you can shine a pure blue light at it and then measure the reflected light intensity with a photodiode. Do the same for red and green light, and you can get an RGB color value. Conversely, you can shine a white light at an object and use three photodiodes with the appropriate color filters to calculate your RGB levels. This sorter, built by Redditor Dumjim, relies on these principles to organize large quantities of beads.

    This machine sorts the kinds of beads used for beadwork crafting. Those may come in individual containers, but they soon end up mixed up. But now, Dumjim can quickly and easily sort those beads by color. It utilizes a 3D-printed frame and mechanisms, which Dumjim designed in Autodesk Inventor CAD software.

  • Cockpit Project: Cockpit 263

    Cockpit used to interfere with browser history. Clicking the back button would frequently get into a loop. Browser history handling is now fixed, so navigating back works as expected.

    Additionally, back and forward buttons have been added to Cockpit Client, the desktop app to connect to Cockpit servers using SSH.

  • Could Crypto Mining Ever Replace Advertising? - Invidious [Ed: The WWW is resorting to malware and Web sites are becoming nothing short of malware]

    I didn't know AmogOS was still being updated but apparently it is and the developer decided to add a crypto miner into the website for the memes but it does raise a more interesting question is this a valid way to fund a website as opposed to advertising.

  • 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.
