👋 Hi, I’m Anil. I work on safety-critical automotive firmware, microcontroller drivers, and functional safety. Outside of work, I’m exploring Linux kernel internals, device drivers, ARM and RISC based systems, networking, and Edge AI through hands-on learning. This account is my engineering notebook—sharing what I learn, lessons from automotive software, and connecting with people who enjoy building systems from the ground up.

I bought my Raspberry Pi 4B (4GB) for ₹5,549. Today it’s listed at ₹11,469. 😅 Looks like my little Linux lab just appreciated better than some investments.

@platput Thanks, I am in Embedded software for automotive domain. Exploring linux and other stuff. started to post the things i learn.

@Anil_Embeded Followed back. Thanks for connecting. What do you do?

I’m documenting my journey of building software and products in public. Expect posts about dev work, cloud, ai coding tools, infra mistakes, and startup lessons. If you’re building too, say hi.

While building a minimal Linux system, I needed a userspace after the kernel booted. That’s where BusyBox came in. BusyBox provides a shell and many familiar Linux commands like ls, cat, and mkdir. Instead of separate binaries for each command, they’re often symbolic links to a single BusyBox executable, which selects the appropriate functionality based on how it’s invoked.

@ShivamS1123 Agree.

Recently completed 1M impression in last two months of positing and interactions. When I started with X, I used to wonder how can I be visible to such a large no of people, specially someone who is new to public building. Most of you must be having the same feeling right? With two months experience, I can answer this now: It simply lies in the consistent efforts while posting and interacting on fellow followers. It’s all with collaboration in your niche. Just stick to posting and let’s grow together.

@VazeKshitij Its nothing bro, we had once power outage for 2 full days without rain.

There was a 14 hour long power cut at my home today man 😭😭😭

Visiting again. #Bosch

Nowadays I spend more time on x than Instagram it seems.

@Ritesh_Yadav_14 Well +1 then.

Never thought I'd be this close to 500 followers. ❤️ Appreciate every single one of you.

@Sousinr +1

Started this account 3 days ago. Today: 150+ followers.🚀 Next goal: 1,000 by the end of the month. Posting every single day. Let's see what consistency can do. 👀

@Ateendriyo Yeah

#Pune peoples: one urgent question. Once it starts raining, does it not stop? Sincerely, A new arrival.

@Mahindra_Auto Does this even make sense?

If you’re in Pune, please stay safe. 🌧️ Looks like the monsoon is making up for lost time by dumping its entire quota at once! 😅

While building a minimal initramfs, one thing finally clicked: The Linux kernel doesn’t magically give you a shell after booting. The kernel executes /init, which eventually starts BusyBox. BusyBox then provides the shell and many of the familiar Linux commands. Tracing that boot sequence made Linux feel much less mysterious.

@TheOneLanceB @smbcapital Interesting observation. It reminds me of embedded software—AI can make you faster, but only if you already know what “correct” looks like. Otherwise, it’s easy to mistake convincing output for a good solution.

IF CLAUDE/AI IS SO USEFUL, WHY ARENT PNLS GOING UP? I just made an important point on the @smbcapital call. You can’t go a day without reading tweets about traders using Claude. For 6 months now, Claude has been the talk of many trader calls. Yet from what I’ve seen, it’s not translating to pnl for most traders. Why? Because almost always, more data and information is NOT the constraint. The traders that outperformed in April did so because of their systems and execution. It isn’t that Claude and AI shouldn’t be used or isn’t at all useful. But AI and Claude can become a distraction AWAY from the actions and changes that actually matter and translate into PNL. If I were a betting man, Claude might have improved workflows for traders, but net, it has probably reduced trader pnl through distraction away from what matters.

I initially thought building the Linux kernel would be enough to boot Linux. It isn’t. You also need a userspace. Building a minimal initramfs with BusyBox was the point where it finally clicked that a booting Linux system is much more than just the kernel.

If you’re starting with Linux kernel development, I’d definitely recommend beginning with QEMU. I first came across it while following @_streetdogg’s Linux videos. Building the kernel, BusyBox, and a minimal initramfs, then booting them in QEMU, made it much easier to understand the Linux boot process before moving to the Raspberry Pi 4B. If you’re getting started with Embedded Systems or Linux kernel development, I’d highly recommend checking out Pyjama Cafe. I found it to be a great resource for building a strong foundation.

@amit_code Congratulations

Today I hit 16.6K followers. 🎉 Two years ago, I started posting with no expectations. Since then, it has led to: → Thousands of meaningful conversations → Incredible opportunities → 100+ genuine connections → $3,000+ earned through X

One thing I’ve realized while learning Linux: On an MCU, I was used to thinking in terms of peripherals and registers. With Linux, the first question is often: “Which kernel subsystem owns this hardware?” It’s a small shift in thinking, but it changes how you approach driver development. For those who moved from bare-metal/RTOS to Linux, was this your experience too?
