Kubernetes is a tool for managing containerized applications, designed to make it easy to deploy and scale applications. It is designed to work with a variety of container technologies like Docker and containerd. In a Kubernetes cluster, your application runs in a Pod. In Kubernetes, Pods are ephemeral; they are temporary resources which are created and destroyed as needed .
When pods need to interact with other resources in a Kubernetes cluster, they can use the IP addresses provided by the cluster. However, this approach has the drawback of requiring developers to manually configure the IP addresses for each pod. Because Pods are temporary resources in a cluster, it is practically impossible to configure IP tables whenever a new Pod is created or destroyed. As a result, it is challenging for Pods to communicate with one another using IP addresses.
To solve this problem, Kubernetes has a resource called Service, which gives the Pod a stable IP address to solve this communication issue—making interaction with other Pods considerably more reliable. Services provide a way to expose applications running on a Kubernetes cluster to the outside world. They also allow for load balancing and for routing traffic to the correct application instance. Services can be exposed using a variety of methods, such as a load balancer or an Ingress resource.
In this guide, you’ll learn about Services and its types in Kubernetes, and how to define them using YAML files. By the end of the article, you’ll have a good understanding of Services in Kubernetes.
Kubernetes has become the go-to tool for application deployment. However, it does not offer features for continuous integration and delivery. Continuous delivery can be particularly helpful for larger teams that host and update deployments frequently. One approach to maintaining continuous delivery for Kubernetes is GitOps.
GitOps is a software development practice that relies on a Git repository as its single source of truth. Descriptive configurations are committed to Git and then used to create continuous delivery environments. All aspects of the environment are defined via the Git repository; there are no standalone scripts or manual setups.
In this guide, you’ll learn how to configure a continuous delivery pipeline with Flux for your Kubernetes cluster. You’ll set up this pipeline imperatively by deploying the Flux Prometheus and Grafana monitoring stacks, and declaratively by deploying a ‘2048 game application’ to your Kubernetes cluster.
The last few years have seen a rise in containers-based development, with more programmers coming to understand the benefits of using containers rather than traditional VMs or just bare metal. Kubernetes arose to help scale containers for enterprise use cases and has established itself as the most popular container orchestrating platform. From the beginning of the Kubernetes project, the community of users and contributors has grown fast. As of this publication, it is one of the most popular projects on Github.
I recently read the book Programming Kubernetes, which gives an overview of programming Kubernetes with Golang. As a contributor to the Fabric8 Kubernetes Client, I was inspired to write a blog series that covers similar topics from a Java developer's perspective.
Kubernetes 1.16 introduced the concept of custom resources (CRs), allowing users to define their own Kubernetes objects that can be used in their applications. Users are now able to define these Kubernetes object structures tailored to their needs and use them like native Kubernetes resources. This makes Kubernetes much more extensible. These custom resources can be used by Kubernetes Operators to manage applications and their components.
Kubernetes is less than a decade old as an open source project, but it’s already grown up in tech years.
“Kubernetes as a base platform is quite mature,” says Gordon Haff, technology evangelist at Red Hat. “That’s not to say that change isn’t a constant in and around the platform.”
Indeed, while Kubernetes might seem like old news, the orchestration platform – and the IT pros and teams who use it – still has plenty of new tricks in store.
In this video I discuss how I2P (the invisible internet protocol) could save the dark web and hidden services from certain kinds of DDOS attacks that the Tor network has been suffering from for several months now.
Pinta 2.1 open-source image editor and drawing software is now available for download. This release is a major update that adds WebP support, Gradient tool improvements, and many other exciting changes.

The time command is used to determine the amount of time taken by the referenced command or shell script to execute in your system, from start to finish.
It returns the result in three categories: real time, user time, and system time (we will discuss them later), which can be very useful, especially if you are a sysadmin.
As a sysadmin, you must be aware of the time taken by your server to execute the referenced script. A single script doesn’t affect much, but running multiple complex scripts on your server will result in resource waste.
In this article, you will learn how to use the time command to determine the execution time of a command or shell script taken by your system/server in Linux.
Docker is a popular containerization platform that allows you to package, deploy, and run applications in a container. The `docker exec` command allows you to run commands in a running Docker container. This can be useful for debugging, testing, and administering containers. In this article, we will go over how to use the docker exec command to run commands inside a running Docker container.
Everything is now accessible online and when accessing most services, you must create an account depending on the platform. While creating an account is easy and quick, the hassle comes in remembering all the different and robust combinations of passwords used to create the account.
To be safe, you should not use the same password for your accounts. Therefore, having a way to manage all your passwords for quick autofill and security is essential. With a password manager like LastPass, you no longer have to worry about forgetting passwords. This guide details everything about using LastPass on Ubuntu 22.04.
Manipulating files filled with data is one of the absolute basics of programming. Files need to be split down, reduced, or otherwise modified to be used by a script with particular requirements. Bash, having been around as long as it has, is armed with a lot of tools for such purposes. One of those is the split command, which allows a specific file to be divided according to the instructions put up using the configuration options provided by the user. Today we will see how to use the split command to best suit our varying needs.
The first rule of a progressive Linux user is to ensure that the Linux operating system you are using is up-to-date. The Linux system update and upgrade rules on different Linux distributions depend on the default package manager in question.
For instance, Ubuntu will rely on the APT package manager while a Linux distribution like RHEL will depend on either YUM or DNF package managers.
However, we should not be too quick to dismiss alternate software packaging formats like Snap and Flatpak. Applications under Snap are automatically updated by the Linux system in question. On the other hand, applications under Flatpak do not benefit from the automatic update privilege.
Brief: This article guide breaks down and demonstrates the different package update steps covered under Flatpak software deployment and package management system on a Linux operating system.

In theory I wanted to announce the release of staticsite 2.0, but then I found bugs that prevented me from writing this post, so I'm also releasing 2.1 2.2 :grin:
staticsite is the static site generator that I ended up writing after giving other generators a try.
I did a big round of cleanup of the code, which among other things allowed me to implement incremental builds.
I teach university courses part-time, including a class about general computing topics, open to all majors. This is an introductory course that teaches students about how technology works, to remove the mystery around computing.
While not a computer science course, one section of this course covers computer programming. I usually talk about programming in very abstract terms, so I don't lose my audience. But this year, I wanted my students to do some "hands-on" programming in an "old school" way. At the same time, I wanted to keep it simple, so everyone could follow along.
I like to structure my lessons to show how you got from "there" to "here." Ideally, I would let my students learn how to write a simple program. Then I would pick it up from there to show how modern programming allows developers to create more complex programs. I decided to try an unconventional approach — teach the students about the ultimate in low-level programming: machine language.
The latest version of Boost, version 1.81, is now available in Debian Testing.
As contributors to Boost, we highly encourage you to consider building your package against Boost 1.81 in order to facilitate a smooth transition.
It is New Year’s Day 2023 :sweat_smile:. Happy New Year!!! :fireworks: I am currently driving with my family coast-to-coast on a road trip through the United States, but for New Year’s Eve and New Year’s Day we stayed in one place. Taking advantage of the driving free days, I and my 4-year old son had some great fun with the open-source stable diffusion models; in particular, the Text-Guided Image Inpainting techniques.
debcargo rust repository and some observations. It's been about a week since I first started looking at Debian rust packages and adding some packages in preparation for crosvm. Some things that don't work quite well right now yet. My local branches disappeared. I don't have access and everything is through a merge request, presumably that is not a generally supported workflow and the team members are using branches to manage pending works. ./release.sh is optimized for updates and for new packages, they only build source packages and then I need to rebuild a binary-full package for the NEW queue. Maybe I will figure out. I haven't quite gotten the right IRC client. I was using the web UI but that seemed to disconnect without any warnings, and didn't tell me even when it is disconnected, it just can't post more messages and doesn't receive messages. That's not very useful. I started using Emacs IRC (rcirc) client. Not sure how useful that is.
I made the explicit decision some time last year, but I think the decision itself was the culmination of a long time desire to live more simply, combined with the realisation that I'm not getting any younger. I have been intrigued by the tiny house movement in the past, but at the same time the lure of the canal network in the UK has been floating around my periphery for a good while.
Even with that, I am still at risk of being banned and/or blocked, or de-federated.

Even so, my secondary account on mastodon.sdf.org got deleted with no warning. It was mostly a passive account with one or two posts. Nothing even remotely controversial. Maybe SDF simply doesn't allow secondary accounts. I'll probably never know why it got deleted.
Recently, there have been a couple of cases where instances got de-federated for not acting harshly enough against bad actors (nazis, harassers, or other generally unpleasant people).
Someone else mentioned that Mastodon is a feudal media where local moderators rule. This is a good thing. Actual humans reading posts and reacting will always be better than algorithmic moderation.
ASRock Industrial NUC 1300 BOX and NUCS 1300 BOX series mini PCs are equipped with Intel 13th generation Raptor Lake-P mobile processors up to the Core i7-1360P 12-core hybrid processor with four Performance cores and eight Efficiency cores.
Yesterday, we wrote about the ADLINK Express-RLP COM Express module based on Raptor Lake-P embedded or industrial processors, but ASRock decided to use Raptor Lake-P mobile processors in their industrial “fanned embedded box PCs” coupled with up to 64GB DDR5 memory, and featuring high-speed interfaces such as USB4, 2.5GbE, and more.

ASROCK provides drivers for Windows 10 and Windows 11, all of which are marked “Beta”, but I’d expect Linux distributions to eventually be supported as well.
I would assume most readers of the Adafruit blog know the basics of the capacitor, what they are, what they’re made of, and how they function in a circuit. But, it’s nice to see Digi-Key doing these beginner videos for those just getting started in electronics and working with discrete components.
A previously unknown strain of Linux malware is targeting WordPress based websites, according to research by cybersecurity firm Dr.Web.
Log analysis is not without pitfalls. For example, fail2ban has suffered from a number of issues ranging from annoyances to security flaws. Since there has been recent uh geminews? about pulling strings out of logfiles, and at least one of the fail2ban security flaws involved using bad regular expressions to do that, now might be a good time to review various issues with the practice.
As I wrote in the initial post, I am not an expert in programming and have a non-IT engineering background. Nevertheless I have some coding experience (I do some Python coding every now and then), so I understand the argument, that log-parsing is in the more complex than a CGI script. I also have to say that I wrote this post from my perspective, self-hosting my gemini capsule on a virtual Rootserver, which gives me access to all Logs. I see the point, that not every user has access to this.
I got my hands on a Thumby handheld around summer last year and have been enjoying it since.
If you haven't heard of it, the Thumby is a tiny Gameboy-looking handheld the size of a keychain. No matter how many photos of it you see online, you'll still catch yourself saying "Dang, that's small!" once you see it in person. But here's a photo anyway.
I've been working lately on a bit of an overhaul of how the search engine does indexing. How it indexes its indices. "Index" is a bit of an overloaded term here, and it's not the first that will crop up.
Let's start from the beginning and build up and examine the problem of searching for a number in a list of numbers. You have a long list of numbers, let's sort them because why not.
