The magic is the syscall boundary. When you run cat file.txt: Shell → read() syscall → Kernel → Disk Driver → Disk → back up the chain. Understand this one flow and you understand 80% of Linux. #Linux #SysAdmin #DevOps #Kernel

Layer 3: Hardware 🟡 Hardware — the physical world. CPU · RAM · Disks · Network Ports. The kernel is the only code allowed to speak to it directly. That's why Linux is stable: one misbehaving app can't crash the disk or hijack the NIC.

Linux in one picture: 3 layers, one clean contract. User Processes ⇄ Kernel ⇄ Hardware Everything you do — opening a browser, saving a file, pinging a server — flows through these 3 layers. Here's how 👇

@theliverdoc And Delhi?

Dear friends, I'll be in Bangalore this weekend for book signing and interactive sessions. Please drop in if you are around! Here are the event venues for 20th June 2026: Higginbothams - Ashok Nagar Blossom Book House - Church Street The Bookworm - Church Street The Bookhive - Ashok Nagar Turning Pages - Jakkur

Okay.. @akshay_pachaar’s Hermes article was already top-tier, but his new 47-minute walkthrough is INSANE 🤯 Skip Netflix, grab a coffee, and watch this masterclass on how to build self-improving, 24/7 autonomous agents locally on your machine 👀↓

The name is actually a pun 😄 “Bourne Again” = “born again” → meaning a better reboot of the original. So when you use Bash, you’re using a modern evolution of one of the earliest Unix shells. Follow for more simple tech breakdowns 🚀

Bash is the most popular shell on Linux. Its full name: Bourne Again Shell 🔁 It was created as an improved, free version of an older shell called the Bourne Shell (sh), built in the 1970s.

What is Bash? If you’ve heard this term while using Linux and felt confused—don’t worry. Here’s a simple, clear explanation that actually makes sense 🧵

In simple terms: A shell is a program that interprets your commands and tells the OS what to do. It’s called a “shell” because it wraps around the kernel—like a shell around a nut 🥜 Follow for more simple tech breakdowns 🚀

That’s where the shell comes in 🧑‍🍳 It acts like a waiter: • Takes your order (commands) • Translates it for the kitchen (kernel) • Brings back the result Without it, you couldn’t “talk” to your system easily.

What is a “Shell” in Linux? Most explanations are confusing. Here’s the simplest way to understand it—with a real-life example 🧵

@geebereal99 How much does it cost and how much efforts everyday. I am urdu speaking.

@geebereal99 What a swashbuckling explanation! Being fluent in Urdu and English, I gave Arabic a shot, but I ended up dropping it due to its sheer complexity

One concept. Three ways to say it. a - 1 - 2 - a - 3 for masculine. Ahsan. Akbar. Ahmad. 1 - u - 2 - 3 - a for feminine. Husna. Kubra. Sughra. "Akthar" (أكثر) + word when neither pattern fits. A system. A feminine form. And a backup. Arabic always has a way. I teach Arabic as a system. Not as a word list. Private 1-on-1 lessons. UAE dialect, real conversations, cultural fluency. geebereal.com

I want to teach you something about Arabic that will change how you see the language. There's a pattern that turns any word into its "better/best" form. Once you learn it, you can do it with almost any word. And it takes five seconds. Let me show you how.

@iximiuz I just bought the complete bundle. I want to learn out of curiosity but i am not exactly in the software etc field. I started Ubuntu 24.04 expecting some guided course but instead got a terminal window. This i get in my VM based linux too. How to proceed?

@Javedakhtarjadu They will not. And that’s the duplicity

Talibans have legalised wife beating but with out any bone fracture. If a wife goes to her parent place with out the husband’s permission , she will be jailed for three months . I beseech the Mufties and mullas Of India to condemn it unconditionally because it all is being done in the name of their religion
