Fix for Ollama Issue on Windows 11 where it doesn't connect

If you are using Ollama on Windows 11 machine and are encountering the error below: Error: Head "http://0.0.0.0:11434/": read tcp 127.0.0.1:61593->127.0.0.1:11434: wsarecv: An existing connection was forcibly closed by the remote host. Then it is likely that your previous force closure of Ollama left an abandoned process connecting to the said port - 11434. Unfortunately, at least in my case, this process didn't vanish even when I restarted the system that sure troubled me much. The fix that worked for me was to identify the process-id of that rogue/abandoned process and kill it by its process-id. This is done in Windows Powershell (having admin privileges) like below: Find process-id using the command ` Get-NetTCPConnection -LocalPort <port_number> | Select-Object -ExpandProperty OwningProcess ` where you replace the <port_number> with actual port (11434 in this case) and this command outputs the PID of the process. ...

Should I buy refurbished laptop from Amazon?

This post is based on my experience with amazon.in and guess it to be true on all other platforms as well. At least you can check out and verify for these pointers before you make that decision to buy renewed/refurbished laptop on Amazon with your hard earned money. I see this question propping up in several forums and on many different occasions. In the recent past, I had my 5 year old dell laptop that gave up because its motherboard failed. One of the options that I had in my mind was to re-use the HDD and the 16GB DDR4 RAM of that old laptop in the one that I purchase next as secondary. I had come to a conclusion that it is not worth buying a refurbished/renewed laptop at all. Why? For the following reasons, most of which I see as BIG #RedFlags: You got to remember that Amazon provides a platform for 3rd party sellers to sell their products as well. So in your search for refurbished laptops you wouldn’t want to choose some random 3rd party seller who Amazon doesn’t endorse. You...

Understanding the WSL2 Mirrored Networking Conflict

When optimizing your development environment on Windows, you might encounter a frustrating "silent failure" where Docker containers appear to run but remain unreachable via their assigned ports. This conflict typically stems from how WSL2 and Docker Desktop negotiate network traffic. (I had been through this when I tried to set-up my development environment for ReactNative/Expo application in Docker container.) The Architecture: Mirrored vs. NAT By default, WSL2 uses Network Address Translation (NAT). In this mode, WSL2 lives behind a virtual switch with its own IP address. While reliable, it adds a layer of complexity for local networking. (Spoiler Alert: I resorted to this legacy convention for reliability reasons, at the time of this writing having latest stable version of Docker Desktop). Reasons: Good default for general, isolated development; avoids complex network setup. Downsides: Requires port forwarding to access localhost services from Windows; VPNs can brea...

Beyond Grep: Master ripgrep Performance in Claude Code

If you’ve ever wondered why modern AI coding agents like Claude Code (CC) feel so "aware" of your codebase, the secret often lies in a small, incredibly fast tool called ripgrep (rg) . ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. It combines the raw speed of C with the safety of Rust. It is faster than almost every other search tool because it is built on top of Rust’s regex engine, which uses finite automata, SIMD, and aggressive literal optimizations to make searching very fast. It is the engine that allows Claude to "read" your project in milliseconds. Most importantly for developers, ripgrep respects your `.gitignore` . It won't waste time searching through your `node_modules` , `.git` , or build artifacts, ensuring that Claude only sees the code that actually matters. There are 3 distinct ways Claude can utilize this tool? Depending on your codebase size ...

Write ESM, Test CJS: The Pragmatic Blueprint for Expo 54 and React 19 using Jest for testing

Migrating an application platform to pure ECMAScript Modules (ESM) looks great on paper. Modern ` import/export ` syntax, cleaner tree-shaking, and alignment with Node standards are incredibly compelling reasons to make the switch. However, when you bring pure ESM (` "type": "module" `) into the native mobile landscape with Expo 54, React 19, and Jest, you quickly run into a wall of configuration issues. Native mobile architectures rely heavily on custom asset resolution pipelines and deep native bridges that expect a CommonJS architecture during unit testing. The good news? You don't have to give up modern syntax to avoid configuration headaches. This guide outlines the ultimate middle-ground blueprint for your next greenfield Expo React Native project: Write clean ESM code, but run your test runner in standard CommonJS mode .
