=> ↺ Please make please a sudo alias on your Linux box
There is something very passive-aggressive about the Linux sudo command.
Just the idea of referring to yourself as a super-user, as the first two letters of the sudo command infer, is positively hubristic.
The idea of then using the assumed super-user state to demand the Unix-based OS unquestionably perform a function or task is just outright dictatorial. It’s not a good look.
=> ↺ Mastering File Permissions in Linux
Linux is a widely used operating system favored by professionals and home users worldwide. It is well known for its strong security and integrity features.
In computer security, key concepts include confidentiality, integrity, and availability. When it comes to the computer’s file system, file permissions play a crucial role in securing sensitive information (confidentiality), preventing unauthorized modifications to files (integrity), and allowing appropriate access to files for authorized users (availability). In Linux, file permissions can be set using both the graphical user interface (GUI) and the command line in the terminal.

Next.js is a free, open-source JavaScript framework created by Vercel. Developed on top of React, it’s designed to provide an efficient solution for building server-side rendered and static websites. It offers powerful features like hybrid static & server rendering, TypeScript support, smart bundling, and route pre-fetching.

=> ↺ Attackers target the Domain Name System, the [Internet]’s phone book. Here’s how to fight back
The foundational Domain Name System, essentially the phone book for the [Internet], used to be something nobody using the net much noticed, but lately it has become more of a target, and the cost of attacks against it are huge and growing.
Recent events have once again brought issues involving the DNS, as it’s called for short, to the forefront. A new kind of denial-of-service attack called Water Torture is the most recent, but earlier this year has seen other DNS-based attacks on Telsa’s network in January and a new malware toolkit called Decoy Dog that targeted business networks.

That action saw the exec intone the following:
"I need my Trash back, it is where I keep all my important mails."
"Needless to say, because of the limited time available to my team, the one folder we hadn't migrated was the Trash," Curtis lamented.
=> ↺ The theory versus the practice of "static websites"
The first thought is that in practice, things look different on a long time scale. The use of static files for web content has proven extremely durable over the years. Although the specific web servers and hosts may have changed, both the static file content and the general approach of 'put your static files with .type extensions in a directory tree' has lived on basically since the beginning of the web. One pragmatic reason for this is that serving static files is both common and very efficient. Since it's commonly in demand even in dynamic websites, people who only have static files can take advantage of this. Being common and 'simple' has meant that serving only static content creates a stable site that's easy to keep operating. This is historically not the case with dynamic websites.
The second thought is that one reason for this is that static websites create a sharp boundary of responsibilities with simple, strong isolation. On the one side is all of the complexity of the static web server (which, today, involves a bunch of dynamic updates for things like HTTPS certificates). On the other side is those static files, and in the middle is some filesystem or filesystem like thing. What each side needs from the other is very limited. Any environment for dynamic websites necessarily has no such clear, small, and simple boundary between the web server and your code, and on top of that we're unlikely to ever be able to standardize on a single boundary and API for it.

While running any operating system, a user will find himself in a situation where he wants to know all the hardware details.
=> ↺ How to Delete HUGE (100-200GB) Files in Linux
In the realm of Linux terminal operations, a range of Linux commands are at our disposal for the purpose of effectively deleting or removing files.
When it comes to the task of file elimination, we commonly rely on the “rm” command, which swiftly erases files from the system. For enhanced security and assurance, the “shred” command comes into play, ensuring the thorough and secure deletion of a file, leaving no trace behind.
