Prompt engineering is an emerging discipline that involves developing and optimizing prompts to efficiently use language models (LMs) for a wide range of applications and research topics. In recent years, there has been a growing interest in large language models (LLMs) due to their impressive capabilities in natural language processing tasks, such as language translation, summarization, and question answering. However, LLMs are not perfect and often require specialized skills and techniques to use them effectively....

Introduction I built a Nodejs project over the weekend. Just thought I’d share and guide others with the design and build process of a scalable backend service with Node.js, TypeScript, Nginx and Docker without using any existing Nodejs frameworks. I used the find-my-way router to implement a REST API. And for the database, I’m using PostgreSQL because it’s reliable and scalable relational database. The aim was to build a backend service that can handle thousands of requests per second without any performance degradation....

Running a WordPress blog on a VPS (Virtual Private Server) can be expensive, especially when you have just begun writing or in case it’s just a personal travel blog which gets a few hundred visitors per week. The minimum for which you can get a dedicated server hosting is for at least 5$ a month, which might not be a lot for you, but might be worth a lot to someone else....

You’ve just purchased Minecraft Pocket Edition and now you want to play it with your friends. You’ve checked out realms but you’re not ready to shell out ~ 10$ per month for a realm. The better alternative to Minecraft PE Realms is having your own Minecraft PE Server. A server will give you more flexibility and features in terms of customizability to realms and you can invite your entire group of friends or strangers to join the server and have fun together....

The cloud Game Streaming sector is heating up in India. Nvidia recently jumped into the fray with the launch of its own game service called the GeForce Now. The chipmaker has opened its cloud-based game streaming service, which is set to take over Google Stadia in North America and Europe, to memberships. However the GeForce Now in India is still a long way away from becoming a reality. Currently the GeForce Now service is only open to users across Europe and North America....

Amazon Cognito provides authentication, authorization, and user management for your web and mobile apps. Your users can sign in directly with a user name and password, or through a third party such as Facebook, Amazon, or Google. The two main components of Amazon Cognito are user pools and identity pools. User pools are user directories that provide sign-up and sign-in options for your app users. Identity pools enable you to grant your users access to other AWS services....

Looking for a lightweight VPN client, but are not ready to spend a monthly recurring amount on a VPN? VPNs can be expensive depending upon the quality of service and amount of privacy you want. A good VPN plan can easily set you back by 10$ a month and even that doesn’t guarantee your privacy. There is no way to be sure whether the VPN is storing your confidential information and traffic logs or not....

How fun would it be if you were able to monitor the real time temperature and humidity of your home or work location? In this tutorial we’re going to do just that. First of all, we’re going to setup a Raspberry Pi equipped with a DHT-22 Temperature and Humidity sensor to capture real time readings. Then we’re going to push these captured metrics to InfluxDb – a time series database. Finally, we’re going to set up Grafana on our Raspberry Pi to create real time graphs of the temperature and humidity fluctuations....

In this tutorial, I’m going to explain how to set up your Raspberry Pi 3 without using a monitor or any other input-output devices. The setup is divided into 5 simple steps. Follow the steps to setup your Raspberry Pi in a headless mode, i.e without a keyboard, mouse or even a display. This is especially helpful if you’ve just got your Raspberry Pi and you don’t have anything else than just a power cable and a SD-Card....

When it comes to working with unix systems monitoring them plays a very significant role.

In this article I’ve aggregated a list of the most common linux commands used for monitoring the current state of the system. On a system with GUI, you can achieve this using a Task Manager or Activity Monitor....
