  • LLVM/Clang 9.0 Picks Up Support For Arm's Cortex-A76

    For those interested in Arm's Cortex-A76 that was announced last year, this CPU with "desktop-class performance with smartphone efficiency" is now supported by the LLVM Clang compiler.

    As of this Clang commit and this LLVM commit on Monday, there is back-end support now wired up for the Cortex-A76 and Cortex-A76AE. With the cortex-a76 and cortex-a76ae values for -mcpu=, the Clang compiler can generate optimized machine code for this Arm CPU.

  • Why Programmers Should Learn LAMP Stack Development?

    A stack is basically a bundle of different components that are brought together to form a unified platform designed to perform specific tasks. In most cases, stacks are named depending on the software that it contains. Typically, a stack consists of an operating system, programming language, web server, and database software.

    In this case, LAMP is an acronym that stands for Linux, Apache HTTP server, MySQL, and PHP. It is the world’s most popular platform for web development.

  • Building A Simple Python API for Internet of Things Gadgets

    It’s no secret that I rather enjoy connecting things to the Internet for fun and profit. One of the tricks I’ve learned along the way is to spin up simple APIs that can be used when prototyping a project. It’s easy to do, and simple to understand so I’m happy to share what has worked for me, using Web2Py as the example (with guest appearances from ESP8266 and NodeMCU).

    Barring the times I’m just being silly, there are two reasons I might do this. Most commonly I’ll need to collect data from a device, typically to be stored for later analysis but occasionally to trigger some action on a server in the cloud. Less commonly, I’ll need a device to change its behavior based on instructions received via the Internet.

  • Stack Overflow: Python is on fire, and Kubernetes needs some housecleaning

    Google's Felipe Hoffa just published an excellent analysis of Stack Overflow questions, trying to uncover the direction developers are moving. For example, it's interesting to know that developers have a long-standing affinity for Java (which also shows up in the Redmonk rankings and elsewhere), it's much more interesting (and surprising) to see that Java doesn't crack the top 10 in the most recent quarter, and even vanishes from the top 30 questions (measured by current page views).

    Java, a mainstay for decades, struggles to get noticed with developers today, according to Stack Overflow data. Python, by contrast, is on fire, largely due to its flexibility and applicability to the burgeoning world of data science.

  • The Eclipse Foundation Specification Process

    The Eclipse Foundation Specification Process (EFSP) defines a general framework for developing specifications in open source at the Eclipse Foundation. At the heart of the EFSP is the notion of an open source project and, much like an open source software project, an open source specification project is concerned with creating various artifacts in an open and transparent manner. In the case of a specification project, however, at least one of the artifacts that’s produced is a specification document that describes how software should be implemented.

    The EFSP extends the Eclipse Development Process (EDP). The EDP defines the governance of open source projects at the Eclipse Foundation. This EDP describes, for example, our open source “rules of engagement” (open, transparent, meritocratic), how open source projects are structured, roles and relationships, and our review process around releases. The EFSP adds a few extra checks and balances.

  • Podcast.__init__: - Episode

    Any time that your program needs to interact with other systems it will have to deal with serializing and deserializing data. To prevent duplicate code and provide validation of the data structures that your application is consuming Steven Loria created the Marshmallow library. In this episode he explains how it is built, how to use it for rendering data objects to various serialization formats, and some of the interesting and unique ways that it is incorporated into other projects.

    We owe this evolution to game developers most of all. The web-based graphics engine OpenGL alone has become the standard for the massively popular apps.

  • 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.
