Why Every DevOps Engineer Needs to Fall in Love With Linux (Before Anything Else) When I started learning DevOps, I made the classic beginner mistake. I jumped straight into Docker tutorials, then AWS, then Kubernetes — because those are the tools that show up in every job description and every flashy YouTube thumbnail. Linux felt boring. Old. Something my seniors used because "that's just how it's always been done." It took me exactly one broken container, one failed SSH connection, and ...

Ever been on a trip where everyone keeps asking: "Who paid for lunch?" "How much do I owe?" "Can someone calculate everything?" I've been there more times than I can count. Instead of passing around spreadsheets or scrolling through chat messages, I decided to build Pay Splitter. 💡 The Idea Pay Splitter is designed to make shared expenses simple. Whether you're: ✈️ Traveling with friends 🏠 Sharing rent with roommates 🍕 Splitting restaurant bills 🎉 Organizing events I...

Every page we serve falls into one of four buckets, and they want opposite things from a cache: Marketing pages never change between deploys. Blog articles change when someone hits publish in the CMS. Tenant storefronts change when a seller edits a product — and must never be cached for the seller themselves. The logged-in app must never be cached at all. The obvious move is to split them: blog.grouptizer.com , stores.grouptizer.com , app.grouptizer.com . Separate ...

Coding interviews are scary, especially in the age of LLMs, where cheating has spiked and interviewers are implicitly sus of every movement you make. I wanted to write about my experience with coding interviews. Am I really qualified to write about this? Well, obviously not, my success ratio isn't great. But I've got some experience under my belt (13 coding interviews so far in my relatively short career), and I wanted to jot down what actually works for me. Preparation Figure it...

Most backend features look simple when reduced to one endpoint. Authentication needs login. File storage needs upload. Payments need checkout. A Discord bot needs a command listener. The first version may take only a few hours. Production is where the real work begins. Authentication adds token refresh, revocation, password reset, permissions, MFA, OAuth2, and session management. File storage adds validation, ownership, protected downloads, metadata, storage migration, and safe...

Agent tracing is useful because it reveals execution structure: which step ran, which tool failed, where a retry occurred, how long a model call took, and how the token budget changed. The easiest implementation is to capture every prompt, argument, result, and response. It is also the easiest way to turn an observability system into a second copy of sensitive application data. Metadata-only tracing takes a different approach. It records the behavior of an agent without storing its raw p...

What Is CSS Grid? CSS Grid is a two-dimensional layout system that allows developers to arrange elements into rows and columns. Unlike Flexbox, which is primarily designed for one-dimensional layouts Grid can manage both dimensions simultaneously. why we use grid? CSS Grid is a powerful layout system that makes it easy to create modern, responsive web page designs. It allows developers to arrange elements in both rows and columns, making complex layouts simpler to build and manage. C...

Next.js Server Actions vs tRPC: how to actually choose If you are building a Next.js app with the App Router and trying to decide between Server Actions and tRPC for your mutations, here is the short version: reach for Server Actions when you have simple forms tied to a single web client, and reach for tRPC once you need request batching, query caching, or a shared API layer across web and mobile. Both solve the same underlying problem, getting typed data from the browser to the server witho...

Your Shopify integration works great. Until it doesn't. At 1,000 records a day, a simple loop with API calls is fine. At 500,000 records a day, that same loop becomes an eight-hour backlog, a wall of 429 errors, and inventory numbers nobody trusts. I work on enterprise Shopify integrations, and the pattern is always the same. Teams don't fail because their code is bad. They fail because they scale a small-volume design instead of switching to a high-volume one. These are two different arch...

We had a ticket planning meeting. And by going through the tickets I noticed I hadn't completed a jira story in a long time. I got caught up in finding new things that I wanted to implement as part of the same story. I learned that the story needed clearer boundaries and a clear definition of done. I learned that a product of a story could be another story with another goal and new ideas. I will try to have a clearer focus on the story at hand. If I find new ideas I want to implement I wil...

Last week, I posted about a personal situation where I struggled with Generative AI and how I was able to fix the problem by asking if a real person could help me. I believe that some people got the point of the story, but some comments started piling up, and I thought that a full post following up on that discussion would be better than a long discussion thread. Generative AI Is Basically a Gacha Game The strongest counterargument deserves to be stated properly: Inferen...

The green phosphor of a high-security terminal flickered with a rhythmic, clinical pulse, casting sharp shadows across the workstation of Senior Systems Architect Elias Vance. To a casual observer, the task appearing on his screen looked like routine maintenance—a standard cleanup of legacy data. But in the high-security corridors of the Network Data Sanitization Center (NDSC) in Virginia, the reality was far more profound. This was not a deletion; it was a surgical excision. This was the beginn...

Hey HN! This is Divit from Almanac (YC S26). We built CodeAlmanac, a wiki for your coding agents that updates as you talk to them. It is open-source, local, and free. Here’s a demo: https://www.youtube.com/watch?v=XNQWV3TFBWM Your CC/Codex conversations contain a LOT of knowledge that is forgotten because it was never documented. People have their own methods of documenting their chats. We used to make Markdown files like MANUAL.md and DESIGN.md, and would prompt Claude to keep them updated. T...

Hello HN! We were finding it too much work to keep our Zendesk help center up to date as our product kept changing, so I built DocCharm — it keeps a help center up to date automatically by watching PRs as they land in your GitHub repository. It suggests updates (with AI) to existing articles, or drafts entirely new ones if nothing appropriate exists yet. Everything goes into a review queue first, so a human always checks (and can optionally edit) before anything publishes. In practice this has p...
