If you have already read some of my blogs, you probably know that I don't really like learning things as if they are magic. I usually need to understand the why and the how behind something before it really makes sense to me. Otherwise, my brain just refuses
A while ago, I wrote something about measures of central tendency â mean, median, and mode. Yesterday, I finally finished my statistics test, so I thought this would be a good time to write down my current understanding of statistics as a whole. This is not a textbook explanation, and I
When I start learning a new technology, I prefer to begin with the big picture before diving into implementation details. If I understand why something exists and where it fits into the overall architecture, learning the technical details becomes much easier. Since I'm new to LLMs and agentic
Recently, while exploring generative AI, I randomly came across a question that looked simple at first: "If AI creates something, who owns the copyright?" At first, I thought the answer would be straightforward. Maybe the person who generated the content owns it, or maybe the AI company owns
Rain drizzled softly over the massive glass towers of the Quantum Research Complex as Professor Robert Hayes stood outside the entrance, staring at the glowing logo above the building. THE JONATHAN INSTITUTE OF TEMPORAL PHYSICS Robert smiled faintly. âOnly Jonathan could name an entire institute after himself and still stay
A few years back, when I was working as an Associate Software Engineer, we worked on a batch processing system that handled large amounts of data through Kinesis streams and stored processed records in DynamoDB. At that time, I didnât know much about retry strategies or distributed system failure
One thing I learned while working with DynamoDB single table design is that it should not start only from entities and relationships like traditional relational databases. In single table design, multiple entities are usually stored in the same table, and the structure is mainly optimized around how the application reads
Serverless First, letâs understand what serverless actually means. In the traditional way of building applications, you build your application and host it inside a server. But when doing that, writing the application itself is not the only thing you need to care about. You also need to think about
So when coming to the NoSQL world, itâs a bit different compared to SQL. When I first worked with DynamoDB, I thought, âwhat a wonderful behavior it has.â Everything felt fast, simple, almost like the database was doing less complaining and more working. No strict schemas, no heavy joins,
I have gone through some database notes on my msc program and created this cheat sheet covering some concepts of it will upload the advance one too.
Today I finally sat down and tried to understand vectors properly⌠not just to pass an exam, but to actually get it. And honestly, I wish someone had explained it to me like this years ago. Back in school, vectors were introduced as arrows. In physics, they told us: âa
In Sri Lanka we have this special event called Sinhala and Tamil New Year . Itâs based on the sun moving from Pisces to Aries , so people consider it like the end of the year. Itâs actually the main event for Sinhalese people. During this time, all relatives gather
