  • VK_KHR_pipeline_executable_properties – Developer Log

    Sometimes you want to go and inspect details of the shaders that are used with specific draw calls in a frame. With RenderDoc this is really easy if the driver implements VK_KHR_pipeline_executable_properties. This extension allows applications to query the driver about various aspects of the executable code generated for a Vulkan pipeline.

    I implemented this extension for V3DV, the Vulkan driver for Raspberry Pi 4, last week (it is currently in review process) because I was tired of jumping through loops to get the info I needed when looking at traces. For V3DV we expose the NIR and QPU assembly code as well as various others stats, some of which are quite relevant to performance, such as spill or thread counts.

  • NVIDIA LHR unlock now available for Linux

    This follows the report that the NiceHash team has successfully removed the hashrate limiter from NVIDIA cards. NBMiner is now also available with 100% LHR unlock for RTX 30 GPUs. Both software is closed-source, so we can’t see how exactly was the LHR cracked (it would be very interesting for sure).

    What is apparent here though is that two teams running popular crypto-tools have managed to unlock LHR cards almost at the same time. This raises a question if they shared information with each other and how did they found the method in the first place.

    Our followers have confirmed that NBMiner v41 software does indeed work, which is the first time LHR has been cracked for Linux.

  • [Cryptocurrency]miners Are Bypassing Nvidia's Anti-Mining Technology

    The latest version of NebuTech's NBMiner software has fully cracked Nvidia's Lite Hash Rate (LHR) limiter anti-mining technology on both Windows and Linux, enabling [cryptocurrency]-miners to unlock 100 percent of the cryptocurrency mining capabilities of Nvidia's RTX 3000-series GPUs. The news comes a couple days after Nicehash's Quickminer managed to bypass the LHR limiter on Windows, enabling miners to use the full potential of their GeForce RTX 3000-series graphics cards to mine Ethereum and other cryptocurrencies on Windows-based systems.

  • 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.
