  • PHP 8.0 Ready To Ship With Many New Features, Even Better Performance - Phoronix

    PHP 8.0 is scheduled for release tomorrow on the US Thanksgiving day. PHP 8.0 brings with it many new language features on top of the opt-in JIT compiler support. Here is a look at some of the PHP 8.0 changes along with a quick look at the near final performance of PHP 8.0 on an AMD EPYC Linux server.

    PHP 8.0 is a very worthy successor to last year's PHP 7.4. Besides the JIT compiler there is a ton of work incorporated into this big version bump. Among the PHP 8.0 highlights are:

    - PHP8 introduces the much anticipated Just In Time (JIT) compiler for further enhancing the speed of PHP scripts. More details on PHP's JIT compiler via this Wiki page.

  • Going from Android LinearLayout to CSS flexbox

    Are you an Android developer looking to learn web development? I find it easier to learn a new technology stack by comparing it to a stack I’m already familiar with. Android developers can layout views using the simple yet flexible LinearLayout class. The web platform has similar tools to layout elements using CSS, and some concepts are shared. Here’s some tips to learn web development using your Android knowledge.

  • Software Diagrams Aren’t Always Correct and That’s OK

    Concretely, software is just bits in electronic storage that control and/or are manipulated by processors. Abstractions are the building blocks that enable humans to design and build complex software systems out of bits. Abstractions are products of out minds—they allow us to assign meaning to clusters (some large, some small) of bits. They allow us to build software systems without thinking about billions of bits or how processors work.

    We manifest some useful and generally simple abstractions (instructions, statements, functions, classes, modules, etc.) as “code” using other abstractions we call “languages.” Languages give us a common vocabulary for us to communicate about those abstract building blocks and to produce the corresponding bits. There are many useful tools that can and should be created to help us understand the code-level operation of a system.

    But most systems we build today are too complex to be fully understood at the level of code. In designing them we must use higher-level abstractions to conceptualize, compose, and organize code. Abstract machines, frameworks, patterns, roles, stereotypes, heuristics, constraints, etc. are examples of such higher-level abstractions.

    The languages we commonly use provide few, if any, mechanisms for directly identifying such higher-level abstractions. These abstractions may manifest as naming or other coding conventions but recognizing them as such depends upon a pre-existing shared understanding between the writer and readers of the code.

  • How to Convert Integer into String in Python | Linuxize

    Python has several built-in data types. Sometimes, when writing Python code, you might need to convert one data type to another. For example, concatenate a string and integer, first, you’ll need to convert the integer into a string.

  • How To Install PyCharm on Debian 10

    In this tutorial, we will show you how to install PyCharm on Debian 10. For those of you who didn’t know, PyCharm is an intelligent and fully-featured IDE for Python developed by JetBrains. It also provides support for Javascript, Typescript, and CSS, etc. You can also extend PyCharm features by using plugins. By using PyCharm plugins you can also get support for frameworks like Django, Flask. We can also use PyCharm for other programming languages like HTML, SQL, Javascript, CSS, and more.

    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 through the step by step installation of PyCharm on a Debian 10 (Buster).

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.
