  • Extend C++ capabilities with LLVM STLExtras.h

    The LLVM compiler project provides a header file called STLExtras.h that extends the capabilities of C++ without any dependency on the rest of LLVM. In this article, we take a quick look at its basic functionality.

  • Rewriting Old Solaris C Code In Python Yielded A 17x Performance Improvement

    While we normally hear of rewriting code from Python and other scripting languages into C/C++ when its a matter of performance, in the case of Oracle Solaris it was taking old C code and modernizing it in Python 3 to yield a ~17x performance improvement.

    Shared today on Oracle's official Solaris blog was an interesting anecdote about their listusers command being rewritten in Python 3 from C. Oracle's Darren Moffat noted the C code was largely untouched since around 1988 and given its design at a time when systems were less dense than today with hundreds or even thousands of users per system.

  • Python Projects for Beginners: The Best Way to Learn

    Learning Python can be difficult. You can spend time reading a textbook or watching videos, but then struggle to actually put what you've learned into practice. Or you might spend a ton of time learning syntax and get bored or lose motivation.

    How can you increase your chances of success? By building Python projects. That way you're learning by actually doing what you want to do!

    When I was learning Python, building projects helped me bring together everything I was learning. Once I started building projects, I immediately felt like I was making more progress.

  • PyCon 2019: The People of PyCon

    I can’t tell you how amazing it was to meet the individuals I read, listen to, or who make the tools I use.

    I was so happy to meet the authors that helped me to grow over the last few years, especially Dan Bader, Peter Baumgartner, Matt Harrison, Reuven Lerner, Harry Percival , and Lacey Williams Henschel.

    I love podcasts, so it was wonderful to meet Michael Kennedy and Brian Okken in person.

    And I was happy to meet Paul Ganssle, Russell Keith-Magee, Barry Warsaw, and other maintainers and contributors.

    It was a delight to meet Bob Belderbos and Julian Sequeira from PyBites.

  • Find the first non-consecutive number with Python

    Your task is to find the first element of an array that is not consecutive.

    E.g. If we have an array [1,2,3,4,6,7,8] then 1 then 2 then 3 then 4 are all consecutive but 6 is not, so that’s the first non-consecutive number.

    If the whole array is consecutive then return None.

  • Perceiving Python programming paradigms

    Early each year, TIOBE announces its Programming Language of The Year. When its latest annual TIOBE index report came out, I was not at all surprised to see Python again winning the title, which was based on capturing the most search engine ranking points (especially on Google, Bing, Yahoo, Wikipedia, Amazon, YouTube, and Baidu) in 2018.

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.
