I don’t log in to my LinkedIn account anymore, haven’t done so in years. “AI first this, AI driven that,” alright, alright, I get it! You guys absolutely love AI, and I can’t stand the fact that after almost 5(!!!) years, people still talk about it like it’s the best thing since chicken nuggets. Back when LLMs have started showing somewhat positive results when it came to generating less-than-average code, I came to a devastating conclusion: My friends and colleagues might not actually enjoy coding at all. Maybe they just didn’t enjoy coding the way I do—but either way, I was extremely sad and actively burnt out to find that everybody around me jumped on the prompting bandwagon without giving it much of a critical second thought. I could argue that it was partially because of their employers, but it was definitely because they chose and wanted to. They pressed me “It’s the future, aob2f, we don’t need to write code anymore.” “I just tell Claude to do it, and it’s done.” “I don’t write a single line of code anymore, don’t be left behind.” Some even outrageously claimed “Yeah I reviewed Claude’s 40k lines PR in two days, it was good.” I was baffled. Was I in this sick, absent-minded Truman show spinoff? Were these the same smart, even genius individuals that have built and driven the world’s innovation in the past 30 years with their own hands and minds? It got to a point where I started doubting myself. Maybe it’s really that good? I genuinely gave it a thought. Eventually, I reluctantly gave in and tried vibe coding for the first time… You see, up until then I exclusively used AI as a sophisticated search engine. I asked a technical question—got an answer. More than 50% of the times it was inaccurate or a full-on hallucination, and then I validated the result through trial and error. Admittedly it was better than blindly googling niche bugs and finding nothing but a lonely and vague question from 8 years ago on Stack Overflow. But matter of fact—vibe coding was a mi

On July 19th, dozens of teams of high school students will begin a five-day, 630-mile road race from Fort Worth to Fort Stockton in Texas. But this is not your typical contest. The students design and build the cars themselves, using off-the-shelf parts and 3D printed materials. The winner is the team that accumulates the […]

Every patient in the public tour of my care platform is a computer science pioneer. Ada Lovelace has a pain score. Alan Turing is due for a check-in. And every one of them has a patient ID no real system could ever issue, an ID that is wrong the way a date in month thirteen is wrong. None of this is an accident. It is the most useful compliance idea I have had this year. A good fake is a liability Here is the problem with realistic demo data. Under HIPAA, nobody can tell a well-made fake from the real thing by looking. A screenshot of a fake patient named John Smith with a plausible ID looks exactly like a screenshot of a real one. So when that image turns up in a deck, or a tweet, or a forwarded email, someone has to prove it is clean. And the only way to prove it is to go back to the database and show the record does not exist. That is an audit. Every plausible fake carries a future audit inside it. So a good fake does not reduce your risk. It just moves it. The better the fake looks, the more it costs to prove it is one. The safety of a fake is not in how real it looks. It is in how obviously fake it is. A plausible fake needs an audit to clear it. An impossible fake clears itself. The fix is to stop making fakes plausible and start making them impossible. A patient named Grace Hopper with an ID that breaks the format on sight cannot be a real record. Anyone can check that from the pixels alone. No lookup, no audit trail, no meeting. Zero pixels The public showcase at clearpathcare.ai contains zero pixels from the production console. Every screen is a React recreation, rebuilt by hand to look like the product without ever touching it. What broke: An early draft of the marketing screens started as console screenshots with seeded test patients: realistic names, realistic IDs. Then I asked one question the images could not answer: prove there is no real record in this frame. I could not. So I deleted every screenshot and rebuilt the screens from scratch. The rebuilt

I remember when coding interviews happened at a whiteboard, no computer, no internet, just a marker and whatever you could hold in your head. When AI tools arrived, using one in an interview was the red flag. Now the red flag is the candidate who doesn't use AI enough. In about two years, the same tool went from forbidden to expected. And it only gets faster. Every few months another wave rolls in, a model out of some lab, a tool that does something it couldn't last year, and it resets what counts as normal. You ride it, or you let it break over you. Plenty of people imagine a third option, waiting on the beach with their arms crossed until the water goes calm, but the water never goes calm, and it was never going to wait for them. all in I've decided to ride it, in the most literal way I have. All of my code is written by AI now (is it mine at this point?), and somewhere along the way I stopped treating that as a threat to be managed and started treating it as leverage to be spent. I know the engineers who went the other way, who made a personality out of dismissing the tools, and the tools got better anyway while they just fell further behind. Going all in wasn't one decision; it's one I make again every few weeks. A better model ships, and I rebuild a working agent on top of it instead of staying on the old version, because the result comes out better and cheaper. Relying on older models would have been easier, and most people do. Riding means doing that over and over, long after the novelty wears off. I get why people stop trying to keep up. The volume is genuinely insane, more launches in a week than you could try in a month, and it isn't only engineers feeling it now, it's anyone whose work runs on a keyboard. People are overwhelmed and often giving up. But you don't have to keep up with everything; you just can't ignore it all. keep the thinking It means handing a lot of work to AI, and I hand over more every month. It writes code, drafts the first version of

A few months ago, I was searching for a backend engineering job. Every day looked the same: Open LinkedIn Open Naukri Search for Python jobs Open dozens of tabs Read every job description Apply Repeat The frustrating part wasn't finding jobs. It was finding the right jobs . I kept getting recommendations for roles that technically matched my resume because they contained words like Python , Backend , or API , but after reading the description I'd realize they wanted a completely different skill set. I started wondering: Why are job boards still matching keywords instead of understanding what a developer actually knows? That question eventually turned into a side project called Jobspiq . The Problem Imagine these two jobs: Job A Python FastAPI PostgreSQL Redis Job B Java Spring Boot Oracle Kafka Both are "Backend Engineer" roles. A keyword-based system often treats them as similar. As developers, we know they're not. What I Built Instead of matching keywords, I built a system that compares a developer's profile with a job description to understand how well they actually fit. The platform: Collects jobs from multiple sources. Removes duplicate postings. Scores every job based on how closely it matches your profile. Sends alerts only for high-quality matches. Helps track applications in one place. The goal isn't to show more jobs. It's to show fewer, better ones. What I Learned Building the product taught me something interesting. Writing the software was the easier part. Helping people discover it is much harder. That's why I'm starting to build in public and share what I'm learning along the way. If you've ever built search systems, recommendation engines, or developer tools, I'd love to hear your thoughts. You can check out the project here: https://jobspiq.in Feedback is always welcome.

If someone asked me ten years ago what it takes to break into cloud, I would have said "get certified and hope someone gives you a chance." I was wrong. And I watched dozens of freshers follow that exact advice, collect a certification, then sit in interviews unable to explain why they chose one architecture over another. The problem was never knowledge. It was proof. Proof that you can gather requirements from a confused client, design something that works, and actually build it with your own hands. AWS just launched something that helps close that gap. And two of these credentials cost nothing.

Not another multiple-choice exam. You sit in a simulated client meeting powered by generative AI. A virtual customer explains their business problem. You ask questions, uncover requirements, handle objections, and propose an architecture. The AI evaluates your communication, your technical accuracy, and your decision-making in real time. Then you build the solution. In a live AWS environment. Not a sandbox with three buttons. The real console. After that, an automated validation confirms your solution actually works. Complete every assignment in a learning plan, and AWS issues you a badge through Credly. Automatically. No exam booking. No proctored test. Just demonstrated capability across the full workflow. Each badge represents the entire journey: customer conversations, architecture design, hands-on building, and validated outcomes. Not a single quiz. Not one lab. The whole thing.

The recall comes as the top automotive safety regulator in the U.S. has warned AV companies about their vehicles interfering with first responders.

How I went from toggling a single GPIO pin to deploying intelligent, low-power firmware on the edge — and the lessons that shaped me along the way. The first program I ever ran on a microcontroller did exactly one thing: it blinked an LED. No operating system. No framework. No safety net. Just my code, a register, and a clock ticking a few million times a second. When that LED finally blinked at the rate I intended — not too fast, not stuck on — I felt something I hadn't felt writing software before. On a bare-metal system, nothing happens unless you make it happen. There's no runtime quietly cleaning up after you. That mix of total control and total responsibility is what pulled me into embedded systems, and it's the same thread that eventually led me to running machine learning models on the edge. This is the story of that journey — from a single blinking pin to intelligent devices that sense, decide, and act on their own. The Bare-Metal Beginning Bare-metal firmware is where you learn what a computer actually is. When you write to a memory-mapped register to toggle a GPIO, or configure a UART peripheral one bit at a time, there's no abstraction hiding the hardware from you. You read the datasheet. You read the reference manual. You get the clock configuration wrong, and nothing works — no error message, just silence. Then you fix it, and suddenly bytes are streaming out of a pin at exactly the baud rate you configured. Most of my early growth happened writing low-level peripheral drivers — UART, SPI, I2C, GPIO, ADC — on ARM Cortex-M platforms. These are the unglamorous building blocks, but they teach you the discipline embedded work demands: Every byte and every milliwatt matters. On a resource-constrained MCU, you don't get to be careless with memory or power. Timing is a first-class citizen. An interrupt that fires 50 microseconds late can break the whole system. The hardware is always right. If your code and the oscilloscope disagree, the oscilloscope wins. Th

There are beginner mistakes. Then there are "I spent three days doing the wrong thing" mistakes. This is one of mine. When I first joined a company as a trainee, I was excited... and completely unprepared for real-world software development. Back in college, our web development classes mostly covered HTML and CSS. We did touch a bit of programming, but if I'm being honest, many of our projects involved copying code, tweaking a few lines, and hoping everything still worked. I graduated knowing how to make things look nice , but not necessarily how professional development teams solved problems. Reality hit pretty quickly. Our First Task A few days into training, my friend and I were assigned our first real task by our senior team lead. He gave us an Excel file. It had two sheets , each with roughly 1,000 rows of data. Every row had around 7 to 10 columns . Then he said something like: "Import all of this into the database." Simple enough... right? Well... Neither of us had ever imported data into a database before. Asking the Wrong Person Instead of asking our team lead for clarification, we asked another trainee who happened to be our former classmate. His advice? "Just make an INSERT INTO script." Perfect. Say no more. Without questioning it, my friend and I started generating SQL INSERT statements. One row. After another. After another. And another. By the end, we had spent almost three days creating what felt like an endless wall of SQL. At the time, we were actually proud of ourselves. "Look at us. Future software engineers." Looking back... We were basically expensive copy-paste machines. The Reality Check Our senior team lead eventually came over to check our progress. He looked at our SQL file for a few seconds. Then smiled and said: "You tricked me, huh? That's not what I meant." My friend and I just stared at him. Confused. We thought, "But... the data is going into the database. Mission accomplished, right?" Wrong. What he actually wanted was a CakePHP scr
