Is Language Intelligence?

Sat, 15 Aug 2026 00:00:00 +0000

Less than five years ago, it would have been difficult to imagine that one of the most impactful and transformative advances in artificial intelligence would come from what, on the surface, looks like one of the simplest forms of AI, that deals with one of the most simplest form of data: text.

At the time, much of the excitement in AI was centred around increasingly sophisticated models for computer vision, robotics, reinforcement learning, speech, and other specialised domains. Computer vision systems were becoming remarkably good at recognising objects, generating images, understanding scenes, and even creating entirely new visual content.

One of the most challenging things I have found as a parent is being available whenever my son need help. While I would love to be there whenever my son asks for help with his schoolwork, work and other commitments don’t always make that possible.

I often find it difficult to ask him to wait when he comes to me for help, particularly when he is motivated and wants to learn something in that moment. And I am sure that, at times, having to wait has also made him a little less motivated.

Smash Burger Recipe

Sun, 02 Aug 2026 00:00:00 +0000

Nothing beats a juicy, flavorful burger cooked to perfection. The secret to a great burger is in the technique. Previously, I made the burge patties first by mixing all ingrediants first and then grilled those. But then I discovred the smash burger method, and it has been a game-changer. By smashing the patty onto a hot griddle, you create a delicious crust that locks in the juices and enhances the flavor. This recipe will guide you through making the perfect smash burger at home, complete with all the fixings.

Building Deep Research Agents with LangGraph: From Search to Deep Research

Sun, 24 May 2026 00:00:00 +1000

A single search-and-summarize pass can answer straightforward questions, but it tends to break down when the task requires breadth, evidence coverage, and the ability to recognise what is still missing. Deep research is less about making one particularly clever model call and more about designing a workflow that can plan, gather evidence, assess that evidence, and deliberately search again when necessary.

In this tutorial, we will build a simple deep research agent pattern with LangGraph that plans, searches in parallel, reflects on evidence quality, loops when needed, and only then writes a final report. The architecture that I will talk about here is very similar to the architecture that I have used within the research team in my personal project FinAI.

Laksa Recipe

Fri, 15 May 2026 00:00:00 +0000

In wintertime, nothing warms the soul like a bowl of hot, spicy soup. Laksa is an ideal choice for a cozy meal, combining the richness of coconut milk with the bold flavors of Southeast Asian spices. This is my version of the classic dish, perfect for a comforting weeknight dinner. I don’t like the method of using store-bought laksa paste. Therefore, everything is made from scratch in this recipe, but the recipe is straightforward and can be easily adapted to your taste preferences. Whether you like it mild or extra spicy, this laksa will hit the spot.

Your Personal AI Investment Advisor

Thu, 30 Apr 2026 00:00:00 +0000

I am not a heavy stock market investor, but I have a keen interest in finance and investing. As a result, I occasionally invest a small portion of my savings in the stock market. However, I often find myself overwhelmed by the sheer volume of information available and the complexity of making well-informed investment decisions.

I don’t have a formal finance background, and keeping up with the latest market trends, financial news, company developments, and analyst commentary can be challenging. More importantly, making sense of all that information and turning it into a coherent investment decision is even harder.

PyTorch Fundamentals

Sun, 01 Feb 2026 00:00:00 +0000

PyTorch is one of the most widely used frameworks for building and training neural networks. At the centre of PyTorch is the tensor.

A tensor is a general-purpose numerical data structure that can represent anything from a single number to a high-dimensional collection of values. Neural-network inputs, model weights, activations, gradients, images, audio representations, and many other objects are represented using tensors.

If you are using an Apple Silicon Mac, PyTorch can also take advantage of Apple’s GPU through the Metal Performance Shaders (MPS) backend.

River Flows In You — Yiruma

Sun, 01 Feb 2026 00:00:00 +0000

River Flows In You by Yiruma is one of my favourite piano pieces. I have been playing it for some time now, and it never fails to bring a sense of calm and stillness. The melody is deceptively simple yet deeply expressive.
