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...

Ollama Cheatsheet

I have been using Ollama for a good while now to run LLMs locally on my laptop for better testing and development of my AI Agents. This post shows a number of things that you can do with Ollama in a glimpse and so I call this a cheatsheet. -- -- If you haven't tried your hands on Ollama, you should give it a try and this cheatsheet should come handy to you. And you may want to star it and fork it from my github-gist , for your quick reference and fiddling.

Android Activity's onDestroy() Ain't Your Reliable Friend

Look at the Android Activity life-cycle events in the picture beside. The lifecycle isn't something new. You're familiar with it right? You're also that good Android developer that writes clean code, wherein you consciously override onDestroy() method to include resources clean-up code and save some state, right? Per Android doc , it is okay and usually the practice to write cleanup code in this method but not anything beyond that. So if you are to write code to persist state in this method, or anything else beyond resource clean-up (like threads associated with an activity), you're better off to push it up the life-cycle, either in onStop() or onPause() method. That is how I settled in the first iteration of new learning but wasn't happy. Why? To quote Android Doc:

Book Review: Mango Millionaire - Smart Money Management for a Sweeter Life

Unless you are a core finance guy dealing in financial instruments, do not ignore reading this book. It is not what you don't know that hurts but that which you think you know but don't. Typical me is a curious cat that constantly evaluates its environment. I have talked to many folks who have invested in Stocks and MFs in our generation and earlier to learn from their experience and play it out in my investment game. In social media era, we see a lot of folks blindly taking a punchline or two from various forums in different social media platforms as guidance to employ it in their investment journey. We all have done this and felty guilty of blindly following without reasoning right? This book and such books that take Indian context is targeted at the million retail investors like you and me who are wanting to learn about the stock market and the various opportunities that can be tapped into based on our taste and appetite. I picked this book literally for the respect and ad...
