  • How to Remove an Item From a List in Python (remove, pop, clear, del)

    In Python, we use list methods remove(), pop(), and clear() to remove an items (elements) from a list. Moreover, you can delete items using del statements by specifying a position or range with an index or slice. Python remove(), pop(), and clear() methods are used to remove items from a list. All these methods are discussed in this article. So let’s get started.

  • SVM Sklearn In Python

    Support Vector Machine is one of the classical machine learning algorithm.

    It will solve the both Classification and Regression problem statements.

    Before going deep down into the algorithm we need to undetstand some basic concepts

  • Will Kahn-Greene: Markus v3.0.0 released! Better metrics API for Python projects.

    Markus is a Python library for generating metrics.

  • Meetings, ugh! Let's change our language - Benji's Blog | Benji's Blog -

    I’ve seen teams after a day of ensemble (mob) programming. Exhausted, yet elated at the amount they’ve been able to achieve together; at the breakthroughs they’ve made. Yet a group of people, working together, on the same thing, sounds an awful lot like a meeting. Aren’t those bad‽

    Teams who make time together for a full day of planning, who embrace the opportunity to envision the future together, can sometimes come away filled with hope. Hope that better things are within their grasp than they previously believed possible.

    Yet the more common experience of meetings seems synonymous with “waste of time” or “distraction from real work”. Why is this? Why weren’t they useful?

    One team’s standup can be an energising way to kick off the day. Hearing interesting things we collectively learned since yesterday Deciding together what that means for today’s plan; who will work with whom on what?

    For another team it may be a depressing round of status updates that shames people who feel bad that they’ve not achieved as much as they’d hoped.

  • LLVM Lands Support For OpenMP Offloading To AMD Radeon GPUs - Phoronix

    AMD has been maintaining AOMP as their downstream of LLVM Clang for supporting OpenMP offloading to Radeon hardware. But exciting is this merge request after one month of review now being mainlined for allowing OpenMP offloading toolchain for the AMDGPU back-end.

    At the moment it looks like AOMP still has some patches not yet upstreamed into LLVM but great seeing definite progress in this area. We'll see though if AOMP is still going to be maintained moving forward for new/premature code for AMD support prior to it being mature enough for upstreaming or if AOMP will ultimately be phased out from their ROCm compute stack. Via the AOMP repository is sample code and more.

  • Dirk Eddelbuettel: RcppFastFloat 0.0.1: New Package, Already on CRAN

    A new package, once again based on wonderful library by Daniel Lemire, is no on CRAN in its initial version 0.0.1. Daniel, in a recent arXiv paper shows that one can convert character representations of ‘numbers’ into floating point at rates at or exceeding one gigabyte per second. His tests show a fourfold gain over library functions such as strtod.

    These are some of the things I think about when trying to write clean, readable code.

  • Oracle sweetens Java SE subscriptions with a spoonful of free ‘GraalVM’ runtime said to significantly speed Java

    Oracle has sweetened its Java SE subscriptions by tossing in a free entitlement to use GraalVM, a new universal virtual machine that Big Red says runs just about anything faster, anywhere.

    Reader: The Register confesses GraalVM had escaped our attention until today. The project’s GitHub page tells us it’s “a universal virtual machine for running applications written in JavaScript, Python, Ruby, R, JVM-based languages like Java, Scala, Clojure, Kotlin, and LLVM-based languages such as C and C++.”

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.
