  • GCC Sees More Progress On Ability To Parallelize The Compilation Of Large Source Files

    While GCC with GNU Make and other build systems can scale nicely in compiling many files concurrently, there has been an ongoing GCC effort to be able to parallelize more of the GNU Compiler Collection work when compiling large source files. 

    Back in the summer of 2019 the work got underway for trying to address the parallelization bottleneck in letting more of the compiler work be parallelized in larger source files.

  • Namespaces and Scope in Python

    This tutorial covers Python namespaces, the structures used to organize the symbolic names assigned to objects in a Python program.

    The previous tutorials in this series have emphasized the importance of objects in Python. Objects are everywhere! Virtually everything that your Python program creates or acts on is an object.

    An assignment statement creates a symbolic name that you can use to reference an object. The statement x = 'foo' creates a symbolic name x that refers to the string object 'foo'.

    In a program of any complexity, you’ll create hundreds or thousands of such names, each pointing to a specific object. How does Python keep track of all these names so that they don’t interfere with one another?

  • How much fun was EuroPython 2020

    This year I’ve finally got enough courage and will, and I had 2 submissions for #pyconil. COVID-19 had other plans, and #pyconil was canceled

    I’ve told @ultrabug about this (Numberly CTO, Alexys Jacob), after a few weeks he surprised me with telling me he’s gonna present scylla-driver in europython2020, the shard-aware driver we were working on in the last 6 months.

    At the time it wasn’t yet ready nor publish. (Also found out that Numberly were sponsoring europython for years now) Took me a few seconds to figure that he just set me deadline without my consent…

  • 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.
