This month is chaotic. • Resigned from my job • Started creating content on X (late, but better late than never • Moving from SDE → DevOps/SRE officially • Leaving Bangalore after 2 years Funny how life works. Sometimes many things have to go wrong before the right thing starts taking shape. People know me as an SDE. But behind the scenes, for ~1.5 years, I’ve been doing deployments, fixing VA points, handling infra-related work, and slowly moving closer to DevOps without realizing it. Looking for opportunities in DevOps / SRE. If you're in DevOps, SRE, Cloud, or Backend — let’s connect. New journey starts today.

Today I learned that sometimes the computer is telling the truth. I wanted to learn Rust, so I installed it and confidently ran: rustc --version The terminal replied: zsh: command not found: rustc My first thought: "Great. The installation failed." So I checked the installer logs. Everything looked fine. Rust claimed it was installed. My terminal insisted it wasn't. One of them had to be lying. After digging around, I found rustc sitting peacefully inside: ~/.cargo/bin/rustc The compiler was there the whole time. The problem wasn't Rust. The problem was that my shell had no idea where to look. That's when I finally understood what PATH actually does. Every time you type a command like: node docker kubectl terraform rustc your shell starts searching through a list of directories. That list is stored in an environment variable called PATH. It's less like a setting and more like a map. If the program exists but its location isn't on the map, the shell walks right past it and tells you: command not found Not because the program is missing. Because it doesn't know where to search. That small realization explains so many developer headaches. People reinstall Node. They reinstall Python. They reinstall Docker. They reinstall AWS CLI. Sometimes nothing is broken. The shell is simply looking in the wrong places. As someone moving deeper into Linux and DevOps, this felt like one of those boring concepts that suddenly unlocks a lot of things. Today I wasn't debugging Rust. I was debugging how the operating system finds software. Have you ever spent an hour fixing a problem that turned out to be a single missing PATH entry?

Shipped my Kanban app GlassFlow to GitHub Pages and got rewarded with a beautiful blank white screen. DevTools was screaming: GET /src/main.tsx 404 At first, it looked like React or Vite was broken. It wasn't. The problem was GitHub Pages was serving my repository root instead of the production build. My index.html was still pointing to: /src/main.tsx That works during vite dev, but browsers can't execute TypeScript files directly. The actual app lives inside: dist/ └── assets/ └── index-x.js I had configured GitHub Pages to deploy from: main branch + /(root) Which is basically trying to run: npm run dev in a static hosting environment. The fix: Run npm run build Copy dist/ into docs/ Set GitHub Pages source to /docs Keep base: '/GlassFlow/' in vite.config.ts Now the site is live. Lesson: Static hosting doesn't run your app. It serves files. Ship the build, not the repository. If the Network tab is still requesting: /src/main.tsx you're deploying the wrong folder, not using the wrong framework.

Manager: “We need someone to monitor the deployment this weekend.” DevOps Engineer: “Sure. Will there be compensatory off or overtime pay?” Manager: “No, it's part of the responsibility.” DevOps Engineer: “Interesting.” Manager: “What's interesting?” DevOps Engineer: “If I work extra hours, it's called responsibility.” Manager: “Yes.” DevOps Engineer: “But if I leave early one day, it's called lack of commitment.” Silence. 👀 Manager: “Production doesn't sleep.” DevOps Engineer: “Neither do DevOps Engineers, apparently.” The uncomfortable reality: Many DevOps Engineers are expected to: ✅ Handle weekend deployments ✅ Respond to midnight alerts ✅ Join emergency bridge calls ✅ Support production outages But compensation often remains exactly the same. Being passionate about your work is great. Being available 24×7 for free is not a job requirement. Reliability has a cost. And sometimes that cost is paid by the people keeping the systems running. A healthy engineering culture respects both uptime and personal time.

i have tried to understand roles but i am unable to understand it fully not even partially. will try again tomorrow #AWS #IAM

Nikhil sinha@sinhaniik

Most people think AWS starts with EC2, S3, or Kubernetes. It actually starts with IAM. Because before anyone can launch a server, access a database, or upload a file, AWS needs to answer two questions: 1. Who are you? 2. What are you allowed to do? That's exactly what IAM solves. • Users → identities for humans • Policies → permissions written in JSON • Groups → permission management at scale Imagine a company with 100 developers. Without IAM: Everyone gets root access. One mistake can delete production databases, S3 buckets, or critical infrastructure. With IAM: You create individual Users for each employee. Then attach Policies that define exactly what actions they can perform. Example: Allow: * Read S3 buckets * Launch EC2 instances Deny: * Delete production databases But managing permissions user-by-user doesn't scale. That's where Groups come in. Create a "Developers" group. Attach S3 and EC2 policies once. Now every developer added to that group automatically inherits those permissions. Need to give all developers EC2 access tomorrow? Update the group once. 100 users get the new permissions instantly. No manual updates. No permission drift. No chaos. The mental model: User = Who you are Policy = What you can do Group = How permissions scale IAM isn't just another AWS service. It's the security foundation that sits underneath every AWS service you will ever use. If you're learning AWS, understanding IAM early will save you from countless security mistakes later. What's the most confusing IAM concept for you right now: Users, Policies, Groups, or Roles? #AWS #IAM

Great observation. The part that stands out is Microsoft passing while SpaceX rushed into a $60B stock deal days after IPO. That alone raises questions about who saw what. Also, isn’t Composer 2.5 Cursor’s product? If the workflow layer is this valuable, maybe the moat is bigger than just model access?

🦔SpaceX signed a deal to acquire Cursor for $60 billion in all-stock on Tuesday, four days after its Nasdaq IPO at over $2 trillion. Cursor makes roughly $4 billion a year in revenue. Microsoft looked at the deal. OpenAI tried to buy Cursor twice and got turned down. My Take SpaceX went public on Friday and signed a $60 billion acquisition by Tuesday. A company that converts its stock into a deal that size before the first full trading week ends knows the price won't hold. Cursor is a good product but it doesn't own the AI it runs on. It works because it plugs into Claude and GPT. If those companies change their pricing or build a direct competitor, the $60 billion product has a dependency it can't control. Microsoft already owns GitHub Copilot and could have absorbed Cursor into VS Code tomorrow. Microsoft passed. When the company with the most to gain walks away from a deal, the price was probably wrong. SpaceX paid it anyway, in stock that Morningstar valued at less than half the IPO price. Go public and spend the stock before the market figures out what it's worth. Hedgie🤗

@ThierryBorgeat Retail investors: "I'm funding humanity's future." The balance sheet: "You're funding accounts payable."

Oh, I forgot the best part. Months before the IPO, SpaceX took $17.5 billion of old junk debt from xAI and X and parked it on its own balance sheet through a $20 billion bridge loan. The terms? Repaid within six months of listing. So part of the $75 billion that retail and index funds just handed over is already spoken for. Not for Mars. Not for rockets. To clear debts piling up at Elon's other companies. You bought the rocket ship. You're on the hook for the loans. BEST. ENGINEERING. EVER.

Thierry from arvy 🇨🇭@ThierryBorgeat

🚨 SpaceX just pulled off the greatest financial engineering feat of the century. In about a week. Here's everything that happened, in order: – Folded xAI into a rocket company, turning "space logistics" into an "AI infrastructure" story overnight – Priced the IPO at a flat $135. No book-building, no range. Take it or leave it – Floated just 4% of the company. 556 million shares against 13 billion – Raised $75 billion at a $1.77 trillion valuation, near 100x revenue – Lobbied to get into major indices in ~15 trading days. Amazon took years. Forced buying, by law – Handed an unusually large slice of the float to retail. Tiny supply, an army of buyers – Watched the stock rocket past $200, up nearly 20% in a single session – Saw ~46% of the entire float trade hands in one day – Then announced a $60 billion all-stock buyout of Cursor, the AI coding tool – Structured it so the higher the stock trades, the fewer shares it has to print to pay A company losing $4 billion a quarter is now buying AI startups with paper it manufactured out of a 4% float. The scarcity that pumped the stock now makes its shopping spree cheaper. This isn't aerospace. It isn't even AI. It's the finest financial engineering of the century, and it's only week one.

@thaiscbranco_ @CRV @AmplifyPartners AI solved the cost of creation. Now it's running into the cost of curation. The gap between "technically correct" and "actually good" is where most AI products still fail. If Taste Labs can make judgement measurable, that's a much bigger unlock than another model benchmark.

We’re excited to introduce Taste Labs. Our mission is to end AI slop. We’re building the data and infrastructure layer to give AI models and agents taste. And today we’re coming out of stealth, announcing our $18.5M seed funding, co-led by @CRV and @AmplifyPartners AI has nailed objective domains and made it easy to generate anything. But it still feels off. Now, the challenge is judgement. What fits, what feels like you, what’s GREAT. This requires turning a fuzzy, subjective domain into something we can measure and codify. We’re starting with design. There are two sides to cracking this, the foundation model layer and the agent layer: - We’ve already been working with the top frontier labs to evaluate and improve their models, crafting the right post-training data and RL environments. - We’ve also been working with app-layer companies to build the context and verification tools for their agents to produce better, more on-brand, more creative outputs. We want a future where AI feels right. If you’re passionate about this mission, join us!

DeepSeek is proving that AI leadership isn’t reserved for Silicon Valley. While many chased closed ecosystems, DeepSeek bet on open-source research, long-term AGI work, and domestic innovation. A $50B valuation, a founder who kept control, and models that push the frontier despite chip restrictions. China isn’t just catching up in AI anymore. It’s building its own path.

DeepSeek takes the crown as China’s most valuable AI startup after a massive $7.4B raise at a $50B valuation. The unusual part is control: Liang Wenfeng, DeepSeek’s founder, held almost 90% of the company before the financing and invested around $3 B as the biggest contributor. DeepSeek’s bet is to keep pushing open-source models and AGI research, while also helping domestic chipmakers such as Huawei run powerful models despite U.S. chip limits. Other top disclosed investors : Tencent: about $1.5B CATL: about $740M China’s National Artificial Intelligence Industry Investment Fund: about $150M

@T3chFalcon First we wrote code. Then we reviewed code. Soon we'll mostly supervise code. Origin isn't competing with GitHub. It's competing with the assumption that humans are the primary producers of software.

2023: Cursor launches. a VS Code fork with AI autocomplete. 2025: Cursor acquires Graphite. a code review startup. 2026: Cursor launches Origin. git hosting. a direct GitHub competitor. also 2026: SpaceX acquires Cursor through xAI. three years. VS Code plugin to GitHub competitor owned by Elon Musk. the pitch for Origin is genuinely interesting: GitHub was built for humans. Origin is built for agents. the demo showed 22.6 commits per second inside one repo. hundreds of thousands of clones and pushes per hour. because the assumption is that soon it won't be one developer committing code. it'll be hundreds of AI agents committing in parallel, branching, merging, and fixing failures simultaneously. Someone online said: "Cursor needs your code to train their models." You write code in Cursor. Cursor hosts it on Origin. Cursor owns a frontier AI model trained on code. Your code is now the training data for the AI that is replacing you. Microsoft owns GitHub. Microsoft owns the code of hundreds of millions of developers. SpaceX now owns Cursor. SpaceX now wants the code of hundreds of millions of developers.
