Rise of Neural Processing Units (NPU)

In the ever-evolving world of computing, artificial intelligence (AI) is no longer a futuristic concept confined to science fiction. From voice assistants that understand our mumbling at 6 AM to self-driving cars that navigate chaotic city streets, AI has become a crucial part of our daily lives. But behind the magic of AI lies an insatiable hunger for computational power—one that traditional computer processors struggle to satisfy. Enter the Neural Processing Unit (NPU), a specialized hardware powerhouse designed to accelerate AI workloads with brain-like efficiency.

Embracing Growth: My Journey Through the UBS JUMP

Stepping out of one’s comfort zone is often easier said than done. It requires courage, willingness to embrace new challenges, and an openness to change. Recently, I had the incredible opportunity to attend the UBS-sponsored talent development program called JUMP, an experience that was nothing short of transformative. The program brought together a diverse group of individuals from across the APAC region, including Japan, Singapore, and India, with the shared goal of honing our leadership, networking, and teamwork skills. My team comprised 11 highly talented professionals, and together, we embarked on a journey of personal and professional growth under the expert guidance of Ralph Hubacher, one of the best trainers I have ever met.

The AI and the Future of Programming: A Crisis or Evolution?

With the rapid advancements in artificial intelligence, the world is witnessing an unprecedented AI boom. Organizations like OpenAI (ChatGPT), Google (Gemini), Meta_(MetaAI)_ , and DeepSeek are fiercely competing to push the boundaries of AI innovation. My current organization, UBS Group AG, is no exception—fully embracing AI to integrate it across various projects and use cases. The goal? To enhance efficiency, optimize costs, and drive greater revenue.

The Buggy Truth About Technical Debt

The YubiKey Chronicles: A Hardware Hero in a Digital World

How I became a cybersecurity wizard with a YubiKey ? You know those moments when you realize your digital life is hanging by a thread? For me, it was juggling dozens of remote VMs, a GPG key that felt more exposed than an open Wi-Fi network, and online accounts (Google, GitHub, and Cloudflare) that deserved better than “Password123”. That’s when I decided it was time to level up and get myself a YubiKey—the GOAT of hardware security keys.

A Git Release Strategy That’s Worth Your Commit-ment!

First let’s talk about my current release strategy: a lone master branch soldiering on as the sole gatekeeper of my code. It worked so far, sure. But every time someone pushes code (of course via PR) , my team holds its breath, wondering if it’s a blessing or a bug bomb. No judgment here—it’s a rite of passage in the software world.

Spring Data REST: Building RESTful APIs with Ease

Spring Data REST is a module that builds on top of Spring Data JPA, allowing you to expose your repositories as RESTful web services with minimal configuration. It provides out-of-the-box support for common CRUD operations and hypermedia controls (HATEOAS), which helps in creating self-descriptive APIs.

SSH Hardening: Securing Your Remote Connections

Understanding SSH: Secure Shell Protocol Explained

In the realm of cybersecurity and network management, Secure Shell (SSH) stands out as a critical protocol. It enables secure communication over unsecured networks by encrypting data transfers, providing a secure channel for executing commands, and managing remote systems. In this blog post, we will explore SSH in detail, including its features, benefits, and practical examples.

Mastering Secure Authentication and Authorization with Spring Security

In the dynamic world of web applications, ensuring robust security measures is non-negotiable. From protecting user data to safeguarding against malicious attacks, developers must adopt powerful tools to fortify their applications. Enter Spring Security: a versatile framework that simplifies the implementation of authentication and authorization functionalities in Java applications. In this blog post, we’ll explore the fundamentals of Spring Security and provide practical code examples to help you get started.

Exploring the Raspberry Pi 5: Features, Performance, and Projects

The Raspberry Pi has long been a favorite for tech enthusiasts, hobbyists, and educators. I possess three different Raspberry Pi models, and my recent purchase was RPi 5. With each new release, the Raspberry Pi Foundation continues to push the boundaries of what can be achieved with a small, affordable computer. The Raspberry Pi 5 is the latest in this line of innovative devices, and it promises significant improvements over its predecessors. In this blog post, we’ll dive into the features of the Raspberry Pi 5, explore its performance, and suggest some exciting projects you can undertake with it.

Using GPG Keys for Secure Communication

In the digital age, ensuring the privacy and integrity of your communications is more important than ever. GNU Privacy Guard (GPG) is a powerful tool that helps you encrypt and sign your emails and files, ensuring they remain secure and authentic. This comprehensive guide will walk you through the process of generating, using, and managing GPG keys.

Concurrent Hashmap and Slap!!

Recently I been in a tech chat and was discussing the hashmaps and concurrent hashmap particularly, maybe I couldn’t explain it well and got the slap like a Superman got below. Here in this post I’m trying to explain basics again and few pics which let you know how they work exactly. concurrenthashmap has developed more complex recently till java 12 but we will look at only basic operations to know its foundation.

Core Affinity

Core affinity or Process affinity always playes a great roll for abtaining optimal latency if your application runs with limited threads.

IoT and nodemcu

Bought a brand new NodeMCU couple of days back and i bet its much better than Arduino.

CUDA and Pain with GeForce GT 540M

Nvidia GT 540M is bit old now it was released back in 2012 when I purchased my XPS-L502X this awesome Graphics card was armed with it, Its still very solid to use with it’s 96 CUDA cores, specifications given here.. GT 540M

LM35->Arduino->RPi2

Just to add more fun in tech stuff i have started taking intrest in physical computing and electronics, this extends software field to embedded and electronics where i feel connected to realworld ;)

RC Plane - Preplan

Flying is a great hobby, and i been always a technology hobbyist :)

Sentiment analysis with R

With lot of free time i did a small project based on WhatsApp group chat sentiment analysis with ‘R’. R is a great language for statistical calculations and analytics, this small code sample can show you a showcase usefullness of that.

Alias makes life easy

From couple of years i’m using it but never thought its also shareable with community, alias is helping me shortning big and repeating commands, you just have to declare the short abbreviation of your short command and use it again n again, so here are usage :

Bang-Bang, Be lazy!!

I found another great thing linux provides for the lazy programmers ;) Most of the time we need to repeat the commands we entered in linux terminal and many hardworking engineers typing it again and again ;)

Javascript - ♥ Attach with events

Javascript is going very populer now days, javascript was created in 10 days in 1995 by Brendan Eich, JavaScript was not always known as JavaScript: the original name was Mocha, a name chosen by Marc Andreessen, founder of Netscape. In September of 1995 the name was changed to LiveScript, then in December of the same year, upon receiving a trademark license from Sun, the name JavaScript was adopted. This was somewhat of a marketing move at the time, with Java being very popular around then. I love javascript too much and started digging in that through Node.js which made boom of javascript everywhere as you can use it on serverside too.

Super awesome automation testing

As a born developer i never came across actual/serious testing of softwares, but some times you are the one man army of your project and gotta make all the things yourself.
