Taking notes is essential for learning and retaining information, but without regular review, those notes lose their value. Over time, I’ve discovered that how you revisit and engage with your notes matters just as much as taking them.

Obsidian has become a key part of my daily routine—it's one of those apps I always keep open on my computer. While I started using it for journaling, planning tasks, and reviews, it has now become my main tool for writing blog posts too.

As we approach Advent of Code 2024, I wanted to share my experience from previous years tackling these coding challenges with perhaps an unconventional choice of tools: PowerShell and Pester. While PowerShell is often pigeonholed as just an automation tool, I've found it to be a surprisingly powerful language for algorithmic problem-solving, thanks to its foundation on .NET and its expressive pipeline syntax.

With .NET 9.0, a new set of abstractions has been introduced to simplify integrating AI into applications: `Microsoft.Extensions.AI`. This package offers a consistent programming model by wrapping various AI providers (such as OpenAI, Azure OpenAI, and Ollama), allowing .NET developers to work seamlessly with different models.

If you know me, you know that I love Git, and I believe if you use it right, it can be a powerful tool not only as a version control system but as a documentation tool. With Git, we basically document our code changes over time.

Building a Chrome extension to summarize web pages

The HTML parser treats whitespace characters between elements as text nodes

Browsers and operating systems are increasingly expected to have access to language models. This could really boost productivity, making tasks like translation and summarisation a lot easier.

Here's how I tackle my programming tasks using Test Driven Development (TDD). I first try to understand the problem and then break it down into smaller tasks. TDD helps me do this effectively. I don't use TDD just to write tests; it's a way to manage and solve problems step by step.

I have been playing around with Azure API Management lately and really like it. It's a great way to manage your APIs, essentially serving as an API Gateway to handle incoming API calls and route them to various backend services. The backend service could be any HTTP API, WebSocket, GraphQL, Azure Function, Azure App Services, etc.

RESP (REdis Serialization Protocol) is a binary protocol that Redis uses to communicate with clients. It is a simple protocol that is easy to implement in any programming language. This means that we can communicate with Redis over a socket connection. For instance, here is a naive implementation in C# that sends a command to Redis and reads the response:

In a previous article, I explained how to secure a Blazor application using the Microsoft Identity Platform. In this article, I will demonstrate how to secure a Next.js application. The process is almost identical in terms of the steps required on the Azure portal; however, the implementation differs.

Implementing authentication and authorisation is always a bit of a headache. There's always those edge cases you forget about when doing it yourself. It's smarter to let a third-party service handle Identity and Access Management stuff. Azure's got you covered with Microsoft Entra ID (you might know it as Azure AD).

I use LLMs daily for a wide range of activities, including personal and work projects, as well as for my blog. They help me automate tasks, analyse data, and make decisions, thereby simplifying my life and enhancing work efficiency. Last week, my boss requested a report on our current status, including areas where we are investing more time and money. I had already developed a system to send daily log reports to his email following each stand-up meeting with my team. However...

Every Friday night I try to do something to get my dopamine flowing to start my weekend. Programming is one of the things that does the work for me and increases my dopamine level so much that if I start focusing on something, nothing can distract me. I can keep going for hours after hours without feeling tired, which sometimes isn't good. We should definitely pay attention to our health and get out of the building to connect with real people instead of just sitting in front of the computer coding...

If you're a programmer like me, you might also like making things easier by [automating stuff](https://automatetheboringstuff.com/). This isn't about being lazy; it's about being efficient. For instance, when I'm shopping at [Tesco](https://www.tesco.com/), which is my go-to supermarket in the UK because it's cheaper and right next to my house, I always think about how I can speed up the shopping process. Usually, I rely on a shopping list, but it's time-consuming, especially because I need to carefully check nutrition labels, and what I buy varies depending on things like gym days or cheat meal days.

On April 30, 2023, I was out with my friend, and we were traveling back home from London Waterloo to Guildford.

While on the tube, both of us fell asleep, and my phone was on my lap...

My coworker wrote some Python code to add a signature on PDFs. Since Python isn't my thing, I wrote the same code in a few of my favorite languages. Probably because I haven't used Python in production or because of its wired syntax (Maybe I only like curly-brace languages). Anyway, here's the Python code I mentioned:

On May 4, 2022, I attended a meetup at one of Microsoft's campuses in Reading. This was my first time at a meetup like this. It was about Blazor on .NET 6 presented by Steve Sanderson.

Lately I have been studying some topics in C# in order to improve myself. I think Delegate is one of those topics which is kinda difficult for beginners to initiate with. So, in order to make it clear how it works, I'm going to make some explanations in this post.

Today I was talking with a friend of mine about thinking, The topic is interesting and I wanted to share it with you because as a programmer we are always thinking and trying to find solutions.
