This post traces a TCP packet’s journey through Linux, explaining interfaces, iptables tables and chains, and the networking stack with an analogy, example, and technical details for engineers.
How does data travel from a server to your screen in a split second? What is the logic behind it? What rules and protocols does it use that make it all work?
Learn how to distribute work across multiple goroutines and merge their results back into a single stream using Go's Fan-Out and Fan-In patterns. We'll break down these powerful concurrency patterns with practical examples you can use right away.
A practical guide to metadata, sitemaps, authority, search engines, and how it all actually connects
How to build a reliable task queue in Go using PostgreSQL’s built-in features—no extra infrastructure needed.
Hello, I'm Maneshwar. I'm building *Free DevTools*, a single hub for developers with 50,000+ free resources, icons, cheat sheets, and TLDRs. No login, unlimited downloads.
Want to know if your website is fast enough? Google's Core Web Vitals measure three key things: how quickly your page loads, how fast it responds to clicks, and whether it jumps around while loading. Fix these, and you'll rank better while giving users a smoother experience.
When building modern applications, especially for mobile devices, how you get data from the server to the client is everything. For years, REST has been the standard for API design, but it often comes with frustrations. Let's look at the problems that led to a new way of
eBPF has revolutionized Linux observability and security by allowing sandboxed programs to run in the kernel without changing kernel source code or loading modules
For decades, computers were built for logic -- branching decisions, compilers, databases. But AI flipped the script: today's machines are being rebuilt for one thing above all else -- multiplying matrices at massive scale
Instead of just treating LLMs as black boxes, RML helps us understand which parts of the model contribute to specific outputs.
You’re in the middle of a Teams call with your DevOps crew when a service starts throwing alerts. Requests are piling up, some users are getting errors, and the backend logs look like they’ve been hit by a firehose. You could spin up more servers, but that’s
Meilisearch
Meilisearch is a really powerful search engine; it’s fast, open-source, and easy to set up. But if you don’t configure it properly, especially the indexing and attributes, it can start to feel slow. Let’s say you set up an index with a few thousand records and start
graph
Have you ever imagined a world without connections? Think about your social media full of random unknown people in your follow recommendations, maps not showing the shortest direction between two destinations, or file imports turning into a mess of unrelated modules after compiling. This would be hard even to imagine,
networking
Learn how to leverage Wireshark’s powerful features for effective network analysis and security monitoring
automation
Discover how to automate everyday tasks using n8n—an open-source workflow tool.
Software Engineering is a 75 year old field. The idea of "API" has helped the field grow all this time. In the future, with AI, the number of APIs are going to explode. How are we as a field going to modernize?
ansible
We’ve always believed in building infrastructure like we write software: version-controlled, repeatable, and disposable when needed. For two years, we had credits on AWS, and during that time, we manually spun up servers and ran a self-hosted stack manually: * Nomad + Consul + Vault for orchestration and secrets * NGINX for reverse
security
Linux powers an estimated 90% of the cloud workload worldwide. Linux-based servers are an engineer's favorite when it comes to developing world-class products. But the idea that Linux is inherently secure is a common misconception. In 2022 alone there were around 1.7 million new Linux malware samples.

CAN
In this article, we’ll dive into the CAN (Controller Area Network) Bus protocol by building a hands-on setup using the MCP2515 CAN Bus Module and an Arduino board. CAN is a high-reliability, long-range communication standard designed for microcontrollers and embedded systems—without the need for a central host. It

liveapi
API search is a pain point for developers in large organizations. With sprawling codebases, hundreds of services, and thousands of APIs, finding the right endpoint can feel like searching for a needle in a haystack. At LiveAPI, we’re tackling this head-on by building a system that crawls code, indexes
API
Hey everyone, I'm Shailendra. Recently, I was studying more about APIs while diving deeper into APIs and exploring how the space is evolving, I stumbled upon a few really interesting reports—especially the Treblle API Report for 2024. That got me digging further, and I came across even
