JVM: A Hand in Every Bowl

-

 What is it?

JVM (Java Virtual Machine) is one of the more dominant run time engines (software that allows applications to be run) out there. It supports languages beyond just it’s namesake, include Kotlin, Scala, Clojure, and many others. 

Kotlin allows developers to not just write code that removes unnecessary jibber-jabber eating up their application’s memory during runtime, but also immaculately integrate existing Java frameworks and libraries in their Kotlin code. Scala combines object-oriented and functional programming, offering powerful features like recursion, immutability, and higher-order functions, which are commonly seen in functional programming languages.


Why is it Awesome?

Oracle’s release of GraalVM (an extension of JVM) in 2019 allowed developers to not just make the memory their apps consume minimal, but also include languages like Python and Javascript in their code. It includes a Python 3.8 compliant runtime, allowing Python to run at native, yes, native, speeds. Using this brilliant VM, you can write and execute Python, Java, Javascript, and more languages in just one application. You can’t tell me that’s not awesome.


Hand in Every Bowl?

The JVM is used everywhere. What’s everywhere?

Utilizing frameworks like Spring, Java can be used to make brilliant web applications. The versatility of the language, combined with its security, makes it an amazing choice for nearly every type of application out there. It is also used to make desktop and mobile applications. Minecraft: Java Edition was actually coded in Java (obviously) and is run through the JVM. This allows it to be run on both PCs and Macs.

Java is also used in embedded systems, like Raspberry Pi. It can also be used for cloud based computing, enabled by its platform-independent nature. It also has AI capabilities, utilizing libraries and tools like DL4J and Java-ML, enabling the development of polished ML models and algorithms.

Destiny

Destiny. Fate. Whatever you want to call it. The notion that everything that might happen to an entity is predetermined. People have been known to give their life to this concept, with the faith that whatever destiny has in store for them, will happen, no matter what. So why try? If the future is already written, why should I make an effort to build it? This kind of mentality is extremely, extremely dangerous, which is why it is necessary to clarify what destiny means for me. If we take the most common interpretation of it, destiny is what is behind an invisible and intangible curtain. It is a piece of paper that stretches all the way from our conception to our eventual demise. On the paper is written everything that has happened and everything that will.   Everything that has happened is already in your mind, as memories, and whatever will happen is constantly entering your mind, again, as memories. These remembrances-to-come are not known to you until they have already happened. ...

Hating on What's Popular

Hating on music that is very popular in the world is really really common. Scorning artists like Drake, Taylor Swift, Sabrina Carpenter, Morgan Wallen, Adele, Billie Eilish, Maroon 5, One Direction, The Weeknd, is so quotidian now that it in itself has become mainstream.   Yet so many people listen to them. Drake is raking in 41 million+ streams daily, Taylor Swift is accumulating 64 million streams every day and is on track to overtake Drake as the most streamed artist of all time. So clearly people are listening to these terrible, art-destroying, world-ending, glass-shattering artists.   Numbers don’t lie. People do. The numbers show that the 200 decibel loud hate these mainstream artists get is just noise. People bash them from the outside, but secretly? They’re pressing play. The music’s good. That’s why so many people love it. So why do humans do this? Humans have a habit for rooting for the underdog. Always. No one ever roots for the king, they always root for the poor m...

BMI Estimation from an Image

-
This text details the technical workings of a BMI prediction application built using Streamlit.  It uses a dataset of 526 individuals, and a Random Forest Regression model. The application leverages several machine learning techniques alongside the dlib library for facial landmark detection, aiming to deliver BMI estimates based solely on facial features. Data Preparation The core of this application is a dataset obtained from a publicly available source. This dataset contains facial measurements and corresponding BMI values, which serve as the foundation for training a predictive model. The dataset was preprocessed to exclude missing data, and relevant features were selected for the model. The features considered in the final model exclude demographic factors such as age and height, focusing on physical facial measurements derived from the images. These features were then scaled using StandardScaler to normalize the values, ensuring the model can learn effectively from the data w...
