If you’ve adopted Linux, chances are you might have done so for development purposes. After all, it has everything you need to program in most languages, and do so for (almost) free.
So earlier this year I reviewed the PineBook Pro. I was pretty impressed with it at the time, but am I still enamored with this $200 laptop? I’ve now been using it for at least 90 days. I know that because I haven’t rebooted it in 90 days. Really.

I’m sorry Linux. It’s not me, it’s you. The “year of the Linux desktop” never came to fruition. It was always next year, year after, some year. Now, it’s almost a running joke.
As a developer, I love working with the terminal. The plain, simple, and in my opinion the best way to interact with the computer (also it makes you look geeky)
Since the early days of Unix, the shell has been part of the user's interface with the operating system. The first Unix shell (the Thompson shell) had very limited features, mainly I/O redirection and command pipelines. Later shells expanded on that early shell and added more and more capabilities, which gave us powerful features that include word expansion, history substitution, loops and conditional expressions, among many others.

It is deep work and we take time and turns. We also watch the second season of Star Trek Discovery and enjoy seeing the bright stars of its universe.
I'll start off by dating myself... it was the year 2000. I was in college and the brand new Mini Disk MP3 player had just come out. Superior audio to CD's and the ability to hold hundreds of songs on 1 little disk. Being a broke college kid, it took me about 6 months to make the purchase. Just when I got used to looking cool with my MD player, a wild flash of cool came across the analog airways via a commercial from a company that was only recently regaining its cool with a crappy multicolor desktop PC called the iMac. Of course, I'm talking about Apple. The product was the iPod. I was defeated and nearly threw away my MD player on the spot.
Thanks to the rise of portable devices like the Steam Deck, Linux is gaining more popularity as an operating system than ever before. The platform is built by users, for users, aiming to give them complete control over the software and features on their machine. Unfortunately, this means they’ll have access to fewer popular applications that are available on Windows and Mac — possibly including VPNs. Those having trouble with figuring out how to start should take a look at the 5 best VPN services on Linux, though they might be surprised at how many options they truly have.

Hard links and symbolic links have been available since time immemorial, and we use them all the time without even thinking about it. In machine learning projects they can help us, when setting up new experiments, to rearrange data files quickly and efficiently in machine learning projects. However, with traditional links, we run the risk of polluting the data files with erroneous edits. In this blog post we’ll go over the details of using links, some cool new stuff in modern file systems (reflinks), and an example of how DVC (Data Version Control, https://dvc.org/) leverages this.

Introduction: What is Router OS?The operating system of MikroTik RouterBOARD hardware is MikroTik RouterOS. For those who prefer using a PC as their router,the software may be downloaded and installed on that machine, transforming it into an all-purpose router with all the functionality listed above.Since RouterOS is based on the Linux v2.6 kernel, we wanted to make it as simple as possible to set up and operate, so MikroTik developed it. By setting up your own vps routeros, you may create a safe, private connection between your devices and the Internet, as well as to your other resources.For how to install routeros, go to and get the CD image of RouterOSto get started now. No restrictions apply to the free trial version.
I am on Microverse working with a lot of people new to Software Development with Linux (I use this word to refer to Linux OS and all his derivatives or distros), and in web development we use certain tools and pipelines that are more difficult to set up in Windows. So I found that most of the people new to Linux struggle to set up the tooling and basic commands for the first time.

This is an augmentation article to the one which Mr. Karim has elaborated upon in couchbase blog. If you haven’t read that article it’s better to take a look at it also, so that we can elaborate on in-depth concepts in this article based on what you have learnt from that article. As clear from the title this piece is aimed to dive deep into creating robust solutions for such tools being integrated with basic system design principles. As however cool these hacker like tools may look they must be robust and should be able to scale up to the organizations need. This article can be interpreted as a case-study for Prometheus and Grafana integration with Couchbase-Exporter.

As of today, a program is an interface, a bridge between a computer and a user. There is another word that has been labeled to it, which is called an application. An application would be a good use of anyone's time in making themselves productive. Well, considering the smartphone count in regards to the personal computer count, there are more mobile applications than desktop applications. This leaves a very big grey area for the desktop users, in finding applications that are productive.
