> The shell is the command interpretor in an operating system such as Unix or GNU/Linux, it is a program that executes other programs. It provides a computer user an interface to the Unix/GNU Linux system so that the user can run different commands or utilities/tools with some input data.
> When the shell has finished executing a program, it sends an output to the user on the screen, which is the standard output device. For this reason, it is referred to as the “command interpretor”.
> Structuring or organizing directories is not much different from structuring or organizing other stuff and it really comes down to what makes the most sense to you - at least as long as you're only dealing with your own directories. As soon as you're dealing with an organization, things can very quickly get out of hand.
> The main purpose behind any kind of organizing is efficiency. That really is the keyword. You need to be able to easily and quickly find what you're looking for and just as easily and quickly be able to store what needs to be stored.
> Extension Manager is an app that allows you to install different shell extensions, to make your Linux experience better.
> Extension Manager is a flatpak app on flathub repository, so installing Gnome Extension on your system could be done by using flatpak.
> Zoom has become the world’s most popular video conferencing software. With its easy-to-use interface and reliable video quality, Zoom is great for meetings, webinars, and connecting with colleagues and friends remotely. While Zoom is proprietary software, it can be installed on Linux-based operating systems like Ubuntu.
> For those who are sticking to Firefox ESR, the latest 115 release is now easy to install in all current Ubuntu releases via PPA. Firefox ESR (Extended Support Release) is a slow moving release series target for organizations, including schools, universities, businesses. It has different release circle compare to the general Firefox series.
> I like how Juha-Matti Santala didn’t just think in terms of those categories for themselves but re-bucketed like: [...]
> Originally the discussion sparked somewhat simultaneously in two communities where we discussed the use of tabs in browsers. A lot of people have a lot of tabs open all the time and they never close tabs. That’s their strategy to store things and if the browser would crash and forget the tabs, they’d lose them all which seems to cause a bit of anxiety.
> I personally have never been much of a tabber. If I have more than a small handful of tabs open at any given time, I get anxious. I usually keep a few tabs open as pinned (like mail, calendar) and then very limited amount of tabs I work actively. I close tabs as soon as I no longer need them actively. I’d rather open a site over and over again during the day when I need it rather than keep it open.
> At first, I was going to write an entry about the practical challenges of doing very much of these end to end tests and alerts in our rather different environment. But the more I thought about it, the more I think that this 'user journeys' style of alerting is not entirely generally applicable, or at the least is very hard to apply in some environments. As an outsider, it seems that 'user journey' alerts work best in an environment where you have relatively few user services and these services don't have single points of failure in their implementation, and perhaps you have significant churn over time in how these services are implemented and operated. This often describes web applications, which also tend to come with convenient broad problem indicators in the form of monitoring for certain HTTP error results that signal internal issues.
> One of the things I've become more and more aware of over time as I talk about our metrics, monitoring, and alerting system is that what 'alerts' are can vary quite a bit between environments, despite everyone using the same term and often the same technology to implement their particular form of 'alerts'. Some of the difference in what alerts mean is technological and some of it is organizational (or 'operational').
> This is my take on an introduction. Everyone has their own style, informed by their experience and the types of content they write; there are few hard rules about introductions. Ultimately, it is up to you, the writer, to figure out what you want to say and how you want to say it!
> For individuals concerned about online privacy, Ungoogled Chromium serves as an excellent browser choice. This guide will detail installing Ungoogled Chromium on Ubuntu 22.04 Jammy Jellyfish LTS or the older stable release of Ubuntu 20.04 Focal Fossa LTS; this method will also work with the latest short-term release.
> I recently ran into an interesting warning on newer versions of ARM GCC, including the latest (as of this writing) Arm GNU Toolchain 12.3.Rel1.
> In today’s digital landscape, web servers play a pivotal role in delivering content and services to users worldwide. Nginx, a popular open-source web server, is known for its speed and versatility. However, as your web applications gain popularity, they can become targets for malicious activities, making security a top priority.
> In the dynamic realm of networking, achieving seamless connectivity and swiftly resolving issues are paramount for optimal performance. Enter the “traceroute” command – a network detective tool that reveals the journey packets undertaken across networks.
> Nagios, a powerful open-source monitoring system, is a lifeline for IT professionals tasked with ensuring the reliability of critical infrastructure. However, like any robust tool, Nagios can sometimes become a double-edged sword when it comes to notifications. The constant stream of alerts can quickly overwhelm your team, leading to alert fatigue and missed critical issues.
> In today’s fast-paced digital landscape, where software systems and applications are at the core of most businesses, the ability to respond swiftly to critical alerts is paramount. These critical alerts often signify potential issues that, if left unattended, can lead to system failures, downtime, and ultimately, financial losses.
> In the realm of system monitoring and infrastructure management, Nagios has long been a stalwart companion. This powerful open-source tool empowers administrators to keep a vigilant eye on the health and performance of their IT environments.
> In today’s fast-paced world, staying informed about the status of your critical IT infrastructure is paramount. Nagios, a popular open-source monitoring system, provides comprehensive monitoring capabilities to ensure the health and performance of your systems. One crucial aspect of monitoring is receiving timely alerts when issues arise.
> In the realm of IT operations and infrastructure monitoring, Nagios has long been a trusted ally. Its robust capabilities for system and network monitoring provide valuable insights into the health and performance of your environment. However, effectively managing incidents and responding promptly to alerts generated by Nagios can be a complex task.
> Monitoring your IT infrastructure is essential for ensuring its reliability and availability. Nagios is a powerful open-source monitoring system that can help you keep a close eye on your network, servers, and services. One of the key features of Nagios is its ability to send email notifications when issues are detected.
> In the fast-paced world of Information Technology (IT), where systems are constantly evolving and user demands are ever-increasing, effective IT monitoring is crucial. However, monitoring alone is not sufficient; what truly empowers IT teams is timely notifications.
