At its core, the modulus operation helps you find the remainder when you divide one number by another. It’s often denoted using the percentage sign %. For example, when you divide 10 by 3, the division gives you 3 with a remainder of 1.
In today’s rapidly evolving tech landscape, Site Reliability Engineering (SRE), cybersecurity (Security Operations Center - SOC), and Artificial Intelligence (AI) have emerged as pillars that drive digital resilience, security, and innovation. As companies increasingly rely on cloud infrastructure, demand for a role that merges these three domains has never been higher. The result? A revolutionary new role: the Intelligent Systems Reliability and Security (ISRS) Engineer.
When I open the terminal, I often have to check and update the system using sudo apt update. I thought this process could be made more efficient, so I started considering creating a script that would automatically perform this update only once each time the terminal is opened.
Python is not only popular as a programming language for application development but also quite powerful for automation tasks in the terminal. Here’s a little useful guide to using one-liner Python commands that can help us work efficiently in the terminal.
Recently, I ran into a tricky issue while trying to uninstall Nginx from my BunsenLabs system. Initially, I just wanted a fresh start, but the process ended up being more complicated than I expected, and finding the right solution took quite a bit of time.
Here’s what happened…
return but-in PythonAs usual, let's dive into a bit of experimentation to better understand return, but this time with Python. (I felt uncomfortable with Perl as I mentioned in the previous post.) Anyway, back to Python! In Python, the return keyword is used to stop a function’s execution and give back a value from that function. But there are a few things worth understanding about how it works.
When it comes to scripting in the terminal, programmers generally rely on Bash, Zsh, or other shell scripts. However, since I haven’t thoroughly learned those languages yet and have only picked up a few basic commands to make my work in the terminal faster (pardon my laziness), I initially chose Perl as my main scripting language. As I started using it, I found Perl's syntax confusing and its conventions unusual. Ultimately, I realized that spending time on something that is both confusing and obsolete would only waste my time.
$countAs usual, I’m conducting experiments with Perl. This time, I’m focusing on how variables declared with my behave when used in different contexts. During this experimentation, I encountered an interesting warning when trying to redeclare a variable with the same name. This raised the question: Will redeclaring a variable give me an error?, and what impact does it have on my code?
Let’s talk about looping one more time. I began wondering how exactly looping works in Perl. This language provides several useful types of loops for repeating code blocks: while, until, for, and foreach.
Do you remember the recursion error that occurred in the previous article? I wanted to dig deeper into this phenomenon once again. A quick recap: a recursion error happens when a function continually calls itself without a clear stopping condition, leading to excessive memory usage and eventually throwing an error when the memory stack is exceeded.
