Harden and Secure Linux Servers by Level (1 - 6)

Securing a Linux server is an ongoing challenge. Every day, bad actors attempt to penetrate systems worldwide, using VPNs, IP spoofing, and other evasion tactics to obscure their origins. The source of an attack is often the least of your concerns, what matters most is implementing strong security measures to deter threats and protect your infrastructure. Hardening your servers not only makes them more resilient but also forces attackers to either move on or, ideally, abandon their efforts altog

Using Split Windows With Vim

That's the magic of Vim's split window feature! Think of it as having multiple monitors inside a single screen. And you don't even need screen command or tmux tools for this purpose.

Use Multi-Cursor in VS Code to Edit Multiple Lines Simultaneously

by: Abhishek Kumar Wed, 21 May 2025 02:40:20 GMT Working with code often involves repetition, changing variable names, updating values, tweaking class names, or adding the same prefix across several lines. If you find yourself making the same changes again and again, line by line, then multi-cursor editing in Visual Studio Code can help simplify that process. In this part of our ongoing VS Code series, we’ll take a closer look at this feature and how it can make everyday tasks quicker and

Those Blinking LEDs on Your Raspberry Pi Have Special Meanings

by: Abhishek Kumar Tue, 20 May 2025 03:07:08 GMT While setting up a Raspberry Pi 5 for a new project, I decided to go with a headless setup - no display, keyboard, or mouse. I flashed the SD card, connected power, and waited for the Pi to appear on my network. But nothing showed up. I scanned my network, double-checked the router’s client list, still no sign of the Pi. Without access to a display, I had no immediate way to see what was happening under the hood. Then I noticed something: the

Chris’ Corner: Design Do’s and Don’ts

Anthony Hobday has a pretty good one in Visual design rules you can safely follow every time. Makes sense to me; ship it. Erik Kennedy does a pretty good job with posts in this vein, and I just read one about designing sidebars in his email newsletter. But he didn’t blog it so I can’t link to it. Ins

Scroll-Driven Animations Inside a CSS Carousel

Hey, isn’t there another fairly new CSS feature that works with scroll regions? Oh yes, that’s Scroll-Driven Animations.

Handling Indentation in VS Code

by: Abhishek Kumar Wed, 14 May 2025 03:14:27 GMT Indentation is how code is visually spaced. It helps define structure, scope, and readability. For example, Python requires indentation to define blocks of code. Other languages might not require it, but messy indentation can make code really hard to read (and debug). Common indentation styles include: 2 spaces (popular in JS, HTML, CSS) 4 spaces (common in Python, Java) Tabs (some devs swear by them) VS Code lets you customize indentation p
