  • glibc 2.28 cleanup – no more memory leaks

    glibc already released 2.29, but I was still on a much older version and hadn’t noticed 2.28 (which is the version that is in RHEL8) has a really nice fix for people who obsess about memory leaks.

    When running valgrind to track memory leaks you might have noticed that there are sometimes some glibc data structures left.

    These are often harmless, small things that are needed during the whole lifetime of the process. So it is normally fine to not explicitly clean that up. Since the memory is reclaimed anyway when the process dies.

  • A Brief History of Containerization: Why Container Security Best Practices Need to Evolve Now

    Maybe it’s the advent of the internet, or perhaps your brain skipped all the way back to the steam engine. When asked that question, how many people do you think would land on shipping containers? They might not be the first thing that comes to mind, but the invention of shipping containers in the 1950s catalyzed change. Introducing a standard container helped pave the way for faster, cheaper and more reliable transportation of goods across the globe.

    In many ways parallel to how physical containers shaped shipping, application containers are revolutionizing software development methods. Much like physical containers, application containers are a form of digital packaging. They rely on that attribute to provide virtual isolation for deploying or running various applications that use the same operating system (OS) or cloud.

    Containers support a microservice-based architecture, an approach to redefining large-scale software projects to be more scalable and modular. Container technology can also help make it easier to run applications in different working environments under different conditions because it provides a solid runtime environment. Combined with the open source wave that has permeated the industry, this new wave of development has been a boon to cloud providers, developers and managed services alike.

  • The fight to reclaim the term ‘hacker’ starts here

    In the early days of computing, ‘hacker’ was generally a positive term.

    It started to gain traction through the Unix hack culture that took place at US universities in the ’60s and ’70s – an era recorded in free software guru Eric Raymond’s ‘A Brief History of Hackerdom’ and articles by GNU creator Richard Stallman, among others.

    The inaugural edition of SwigCast – featuring an interview with ethical hackers Paul Johnston and Santiago Diaz – explores these ideas and delves into why better representations of hackers is needed today more than ever.
    
“Right now, ‘hacker’ is used in an entirely different connotation,” said Johnston.

  • Google’s Project Mainline in Android Q will help speed up security updates

    Android version fragmentation is one of the biggest challenges for Google to solve. While the Google Pixel smartphones are among the most secure smartphones on the market thanks to the incredible efforts of Pixel and AOSP engineers, many other smartphones are vulnerable to exploits due to running outdated OS versions or outdated security patch levels. The latest report from Gartner shows that Android 9 Pie is an incredibly secure OS, yet only approximately 10% of all smartphones are on the release.

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.
