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. ...

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...

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...

Cost of AI-Driven Development

AI driven SDLC is perhaps the new norm because of its virality. There is definitive value to AI-SDLC but then we see a lot of noise too. What makes it chaotic is the difficulty in identify noise from value. This can be seen in the way large-scale firing happened in the name of redundancy creating global panic (more than the wars that has been happening at around the same time), followed by some immense mishaps in production systems on account of blind reliance of AI, subsequently taking measures to find a avoid such incidents to save business face by re-looking at all things from hiring to people practices. Personally FinOps is something that I have my eye on incorporating it to the data for making calibrated bets on decisions I make. For the past year, I have been talking and blogging on this subject on the need to focus on alternatives as backup plan instead of relying solely on one vendor. We witnessed vendor lock-in nightmares repeated...

Pro-Grade Java Development in Claude Code - Beyond Grep with LSP

In the world of AI driven coding, context is currency. Most developers run Claude Code (CC) in its "out-of-the-box" state, relying on the agent's internal grep tool to navigate codebases. While Claude is brilliant, grep is a blunt instrument. To transform CC into a true "Senior Pair Programmer," you need to bridge the gap between Pattern Matching and Semantic Understanding . This is where the Language Server Protocol (LSP) and Eclipse JDT.LS come in. 🧠 Why the "LLM is Smart Enough" Argument Fails A common misconception is that the LLM's reasoning capabilities negate the need for local tooling. This is incorrect for two critical reasons: The Noise Tax: When you ask CC to "find all usages of a method," grep returns every string match, including Javadocs, logs, and commented-out code. This "noise" is sent to the LLM, consuming thousands of unnecessary tokens and increasing the risk of the model losing the ...
