Contact meThis was a nice and understandable introduction to ChatGPT, by the noted scientist Stephen Wolfram who is also the creator of Mathematica software. Given that there would be a lot of maths underpinning the workings of ChatGPT, Wolfram does a good job not overloading you with the details. He uses simplified models and lots of […]
I’ve been a casual user of annotations in code for many years but had never bothered to understand how exactly they work, or why they even exist. I would pop in the requisite Hibernate, Spring or Lombok annotations where necessary and get on with it. If the answer to the question “Why do annotations exist?” […]
My summary of some of the talks at Modern Data Stack Conf 2021
This is actually two books masquerading as one. The first is full of great advice on how to identify a genuine customer need and validate it before creating a company around it. In my opinion, you should absolutely read this part, ideally 1-2 years before setting up shop. The second half is largely standard advice […]
After attending a conference called The Makers Summit a couple of weeks back where I saw two founders talk about “10x” products, I figured there must be experts who have looked for patterns in how they emerge and written about them? And sure enough, as I started reading, I discovered there is a market phenomenon […]

The AWS Firecracker paper is fascinating because Amazon has implemented a new Virtual Machine Monitor (VMM) which closely matches the requirements of their AWS Lambda service. While doing so, they carefully navigated the space of existing virtualization options, reused the best parts where they could, and implemented the rest. They also describe how they successfully […]
Given that database transactions have been around for decades, I was surprised to find that some concepts and implementations still don’t have generally agreed-upon terminology, especially across vendors. And even the ANSI SQL standard’s description of Isolation Levels has been found to be lacking in places. I made some notes recently about selected topics in […]
TiDB is an interesting new database, and PingCAP is the company driving most of its development. Recently I read the paper written about it, titled TiDB: A Raft based HTAP database, partly due to my interest in its Rust-based TiKV component. I found the paper to be comprehensive and well written. Below is my bullet […]
If you are familiar with Java or C/C++, understanding the assignment operator (=) in Rust will demystify a lot of its memory semantics. Assignment in Rust can have a range of outcomes depending on what you are assigning from and to, and on whether you are using the reference operator (&) and the mut keyword […]
