  • Kubernetes/IBM/Red Hat: Enable seccomp for all workloads with a new v1.22 alpha feature

    This blog post is about a new Kubernetes feature introduced in v1.22, which adds an additional security layer on top of the existing seccomp support. Seccomp is a security mechanism for Linux processes to filter system calls (syscalls) based on a set of defined rules. Applying seccomp profiles to containerized workloads is one of the key tasks when it comes to enhancing the security of the application deployment. Developers, site reliability engineers and infrastructure administrators have to work hand in hand to create, distribute and maintain the profiles over the applications life-cycle.

    You can use the securityContext field of Pods and their containers can be used to adjust security related configurations of the workload. Kubernetes introduced dedicated seccomp related API fields in this SecurityContext with the graduation of seccomp to General Availability (GA) in v1.19.0.

  • 10 steps to more open, focused, and energizing meetings

    The negative impact of poorly run meetings is huge. So leaders face a challenge: how do we turn poorly run meetings—which have a negative impact on team creativity, success, and even cause stress and anxiety—to meetings with positive outcomes? But to make the situation even tougher, we now find most meetings are being held remotely, online, where attendees' cameras are off and you're likely staring at a green dot at the top of your screen. That makes holding genuinely productive and useful meetings an even greater challenge.

  • Securing malloc in glibc: Why malloc hooks had to go | Red Hat Developer

    Memory access is one of the most basic operations in computer programs. It is also an unending source of program errors in C programs, because memory safety was never really a programming language goal in C. Memory-related issues also comprise a significant part of the top 25 security weaknesses that result in program vulnerabilities.

    Memory access also plays an important role in performance, which makes memory management a prime target for performance tuning. It is natural, then, that dynamic memory management in the C runtime should have capabilities that allow fine-grained tracking and customizable actions on allocation events. These features allow users to diagnose memory issues in their programs and if necessary, override the C runtime allocator with their own to improve performance or memory utilization.

    This article describes the clash between the quest for flexibility and introspection, on the one hand, and performance and security protections on the other. You'll learn why this clash ultimately led to a major change in how memory allocation (malloc) is implemented in the GNU C Library, or glibc. We'll also discuss how to adapt applications that depended on the old way of doing things, as well as the implications for future versions of Fedora and Red Hat Enterprise Linux (RHEL).

  • Instana – One Enterprise Observability Platform: All of the Data – IBM Developer

    IBM Observability by Instana APM provides a comprehensive observability platform for an entire enterprise, able to track requests spanning from mobile to mainframe, and supporting environments from bare metal machines to hybrid multi-cloud deployments.

    Instana automatically discovers, maps and monitors infrastructure, platforms, services and applications in real time, and captures 100% of requests and transactions occurring across the environments.

    To achieve this, Instana provides specific monitoring support for a broad and growing list of technologies, including a large set of programming languages and frameworks, web servers and proxies, messaging systems, and data stores. The following figure shows the technologies and capabilities, platforms, and systems that Instana supports.

  • How do you lead hybrid teams? 5 essentials | The Enterprisers Project

    A growing body of surveys and other research suggests that hybrid workplaces aren’t a short-term fad. Employee interest in a hybrid work model is particularly high: The overwhelming majority (83 percent) of more than 9,300 workers surveyed by Accenture said they’d prefer a hybrid model going forward, for example.

    More business and technology leaders are evangelizing this approach - considering, implementing, or already managing hybrid teams.

    “This is the future of work,” says Vivek Ranjan, chief human resources officer of Zensar. The firm had already embarked on a “work from anywhere” (WFA) transformation prior to the pandemic. It first rolled out in India, where the company has hired 500 remote employees, with plans to expand its hybrid WFA approach to its offices around the globe. “Hybrid workplaces are here to stay,” Ranjan says.

    (Hybrid models entail some defined mix of both in-person and remote work. For more detail and examples, read our related article: What is a hybrid work model?)

    Surveys also suggest there may be a difference of perspective between the C-suite and the rest of the organization in terms of building culture, equity, and other important issues in hybrid workplaces.

  • 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.
