What’s the problem with current Todo. Yet another TODO software or service? Why am I looking at age old matured solution. OpenClaw made me rethink how I interact with my data. For those unfamiliar (don’t tell me?) — Openclaw is a local agent. You run it on your machine. It can take actions on your behalf. Read files, write files, call APIs, automate workflows. The promise of agentic AI, but…
In Part 1 , we traced how the dollar became dominant through three strategic moves — Bretton Woods, the Nixon Shock, and the petrodollar arrangement. Each time the old foundation crumbled, America engineered a new one. Now the question: is a fourth move coming? And who’s trying to make sure it fails? Replace the dollar or get around it? My guess here is - de-dollarization commentary gets wrong:…
Moving money across borders has always been friction wrapped in fees. You initiate a wire transfer. It hops through three or four banks. Each one takes a cut. Two to five days later, it arrives — minus a chunk you didn’t fully anticipate. We’ve lived with this for decades. But something is shifting. Not the fintech marketing — the actual plumbing. Where is real progress happening? A few places are…
Money is just paper. Until it isn’t. The US dollar didn’t become the world’s reserve currency by accident. It took three deliberate, strategic moves — each one transforming the rules of global finance while everyone else was still playing by the old ones. Move one - Replace british pound Move two - Break the gold promise Move three - Oil for dollar How a wartime agreement, a broken promise, and a…
Back in 2019, I jotted down a fleeting reflection on a question that may seem trivial at first glance. It’s the kind of question that feels almost too obvious, woven as it is into the fabric of our daily existence, which is perhaps why it can feel trivial to contemplate. Yet, take a moment to consider it: “Why does it seem as if there’s an unending cascade of issues needs our attention?” Asking…
A product you bought ten years ago costs more today. We all know inflation causes price increases. Why does drop in inflation not decrease the price? Answer: Inflation is compounding. calculator: https://smartasset.com/investing/inflation-calculator Yes. If the price of a product is $100 and inflation is at 4% at the beginning of, say, 2020, this is how the price grows each year. End of Year Rate…
In 2023, we find ourselves at a pivotal moment in the evolution of AI, particularly with the launch of groundbreaking GPT models . This isn’t just a fleeting trend; it’s a substantial shift in the landscape of technology. We’ve seen enthusiasts and professionals alike experimenting with these models, producing content that spans the spectrum from highly practical to purely creative. But the real…
In the world full of problems, solving a problem doesn’t erase the problem, rather transforms into another problem, more like the conservation of energy. Let me give you a simple example. Say, you are looking to shield your car from blazing hot sun and not turn your interior into an oven. You buy a windshield reflector, some side shields to attach to the windows. Now you have effectively reduced…

Refactoring is a must needed exercise in every software module, but everything has its cost. Do not do refactoring if it is absolutely not required. I do not question your intention. If you are tempted to re-factor a large code, ask yourself if it is absolutely necessary. If your refactoring is not going to yield any absolute benefit, then stop it. Many Incremental changes are better If the code…
Circa 2009, when I was testing the mobile webapp in cross platform, Internet Explorer is especially a pain in the neck .

And screw the IE developer tool. Easy fix? Just redefine the…

Back in 2008 I hated it so much and so sarcastic on it. The basic version had only 80 GB harddisk and it was a complete strip down version of then fully loaded laptop (with DVD drives, 4 gig RAM, fast processor, wide screen etc.,). That was the time when the world was ruled by HP, Dell and Lenovo laptops. Now fast forward to 2013 and well I’m owning a Macbook Air 13” with 8GB RAM and i7 processor…

And If you had tried to speak about this to your friend, chances that you would have come across these or…
To be real, you do not. Unless some crazy thoughts running in your mind about your personal projects. You are going to read such a feeling happened to me recently.

When you use blur event in the DOM, general assumption is that event will be fire exactly once when the input field is foccused out either by ‘tab’ or ‘mouse click’. But in a very special scenario, i.e when the Alt + Tab is pressed, the same blur event will be fired…

**Session Affinity** is a technique ( *at the server side* ) which directs the request from the **same client **to the last processed server component(Application server).

Writing unit test cases1 are the part of any development project process. But developers rarely follow process. For us, we wanted to code something and see it to work on what we have fixed and finally move it to production.When it works, we are happy with it. But wait, when it doesn’t work? Then comes a lot of head ache for developer. Ok stories apart, lets get back to work. I’m not going to…
Aggregation and Composition are type of Association which explains how two elements are associated to each other in a class model.

Browser DOM is always created once and the same DOM is referred every time when used (like any other object model). It is not destroyed / deleted unless it is explicitly triggered. But some aspects of browser would make the DOM object reset. For example, during the XHR based requests, more than one page might contain the same script to perform and you are not likely to put them as a common script…

Though different civilizations had different glyphs to…
In my team we were talking about services and then the web services, and when I was talking to a friend of mine about the services stuff, he posted a blank question. "What is a service? and how different is that from a method”. His question is correct, I feel that most of the people who design services in this complex computing world are not still clear what is a service and not sure of how…

Now the revamp in Firefox 3.5 beta has made an improvement in the…
