  • FREE 4 Hour Ubuntu Course for Beginners [Ed: This course must not be too good/factual if they skip GNU and leap to 1991]

    Linux is a well-known operating system. In 1991, Linux was created by a university student named Linux Torvalds. All software’s architecture is covered with Linux, as it helps to communicate between the computer program and the system hardware and also manages the requests between them. Linux is open-source software. It is distinguishable from other operating systems in many ways. People having professional skills related to programming can also edit their code, as it is freely available for everyone. Torvalds intended to name his creation as ‘freaks,’ but the administrator used to distribute the code by its creator’s first name and Unix, so that name stuck.

  • Monitoring failed login attempts on Linux [Ed: Those are GNU programs (grep, head…), not “LINUX”]

    Repeated failed login attempts on a Linux server can indicate that someone is trying to break into an account or might only mean that someone forgot their password or is mistyping it. In this post, we look at how you can check for failed login attempts and check your system's settings to see when accounts will be locked to deal with the problem.

    One of the first things you need to know is how to check if logins are failing. The command below looks for indications of failed logins in the /var/log/auth.log file used on Ubuntu and related systems. When someone tries logging in with a wrong or misspelled password, failed logins will show up as in the lines below:

  • How to Install PHP OPcache on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install PHP OPcache on Ubuntu 20.04 LTS. For those of you who didn’t know, OPcache improves PHP performance by storing precompiled script bytecode in shared memory, thereby removing the need for PHP to load and parse scripts on each request, it simply means any consequent requests for the same script then OpCache stores this script on it memory on the first execution, to be reused afterward, thus leading to performance boosts.

    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 PHP OPcache on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian based distribution like Linux Mint.

13 Best Free and Open Source Python Microframeworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements. A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one. Read more

Valve Backs Zink Work

  • Mike Blumenkrantz: Don’t Call It A Comeback

    I guess I never left, really, since I’ve been vicariously living the life of someone who still writes zink patches through reviewing and discussing some great community efforts that are ongoing. But now I’m back living that life of someone who writes zink patches. Valve has generously agreed to sponsor my work on graphics-related projects. For the time being, that work happens to be zink.

  • Valve Now Funding Blumenkrantz - Zink OpenGL-On-Vulkan To Continue

    Longtime open-source developer Mike Blumenkrantz who has been an Enlightenment developer for many years and was working for Samsung's Open-Source Group prior to its demise jumped into the open-source Linux graphics world this year. While being unemployed he began hacking on the Zink Gallium3D code that allows generic OpenGL acceleration over the Vulkan API. He quickly got the code to the point of OpenGL 4.6 support and quite compelling performance compared to where Zink was at earlier this year. Now it turns out he will continue with his Linux graphics adventures thanks to funding from Valve. Mike Blumenkrantz shared today that Valve is going to be sponsoring his graphics-related work moving forward. At least for now, that Linux graphics work is still on the matter of Zink.
