I love streaming algorithms - they make you think! Since they can process data in (near) real-time, they are ideal for applications where immediate feedback is needed. Most of today's recommendation or machine learning systems are built on batch process, however.
Could be Interesting! Big Data Data ScienceEver heard of Unix Epoch? An epoch is a fixed date and time used as a reference from which a computer measures system time. In Unix and POSIX, this arbitrary date and time is 1 January 1970 00:00, known as the Unix epoch. In a simple term, it is a time counter from 1 Jan 1970. But why do we need it?

IoTAs of 2022, there are ~1.8 billions websites (unique domain names). 17% of all websites, that is, ~300 million are active. The rest are parked domains or similar. Let's unleash another domain to the internet. 😆
Docker WebTechServer-less solution (sort of)... we are paying for cloud service but we don't need to maintain our own server for scaling, security, etc. Popular cloud service providers are Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), DigitalOcean, Heroku and many more.
WebTechPart 2 of Docker to the rescue! A short description of docker compose with a simple example: Docker Compose is a neat way to connect different docker containers as a single service.
DockerOne of the issues we often encounter during software development is that our solution works in the development environment, but when deploy to the production environment, it miraculously stops working! Docker provides a consistent environment across development, testing, and production environments
Flask DockerWhile their transformed data may not be used for further data analysis, T-SNE and UMAP (non-linear) dimensionality reduction techniques provide great values for data visualization!
Data ScienceValues of the features or variables in the dataset are not the same. Even if they are numerical values, their ranges can be quite dramatic. Ensuring that all features are treated equally in terms of scale and range is essential for the performance and stability of many machine learning algorithms.
Data ScienceWhen dealing with high dimensional data (known as The Curse of Dimensionality), it is often useful to reduce the data size for efficient computation. One such method, also very popular method, is Principal Component Analysis.
Data ScienceWhen I started learning about data mining (2021), it confused me. Maybe because I jumped straight into classifcations. There are so many different approaches for data science and I could not quite picture what I am doing. What helps me is structuring the flow..
Data ScienceDo you know that email senders can track whether you have opened their mails, which devices you use, when did you open their emails and how many times did you reopen their mail?
Could be Interesting!Human Brain is amazing! We can recognize shapes, colors and patterns almost instantly. Computing devices does not! That's why we, humans have to teach them image analysis algorithms. This post is part of Computer Vision Series.
Computer VisionThe is the first step to the journey of getting started with Internet of Things (IoT). We prepare the working environment (Conkit) to develop the programs to run on the devices and verify the systems with infamous "Hello, World" Program.

Could be Interesting! Big DataYou know how we always have web version and app version for website? Example: Instagram web-login and mobile-login. Usually that means maintaining both website and mobile app. But Progressive Web Apps make the website to be able to add to home screen of devices (desktop/ mobile) just as native app!

Could be Interesting! WebTechWe all have our preferred learning style. For me, when it comes to learning, I am more of a read, learn and do person. I prefer reading the materials than watching an hour long video. I believe reading gives me time to absorb and digest the knowledge, then, think of the potential implications. However, learning without an implementation is just an entertainment. So, I built and wired up this site to reflect my learnings. (Utilized Flask Framework, containerized with Docker and first deployed on AWS in Jan 2023).
