Previous posts walk through how to run code on an esp32 emulator using QEMU and how to create virtualized sensors for esp32 emulator . This post explains how you can set this up in a way that external applications such as c++/python/nod…
Okay so you've got your esp32 emulator running on qemu. What next? I need to virtualize sensors. That cannot be done really because sensors return environmental parameters, so you can either simulate environmental parameters or generate…
Not having the entire hardware for embedded projects is a pain. It stops the development entirely and is extremely inefficient. In traditional software dev - development, testing and deployment are 3 entirely different phases which are…
Last week Prakriti & I created BitFlash_Client which is now officially a part of the Arduino Library Registry. You can try out the library and let us know if you liked it and if you have any feedback we'd love to hear you out. Also if y…
Hosting websites on a windows server using the IIS - Internet Information Services is painful in 2024 for a new developer. The technology is so old that people who know how to use this are very proficient in it and the documentation is…
As developers, we’ve all been there: you need to share either parts of your code or sometimes your entire codebase with LLMs. The inspiration was drawn from a linkedin post I saw which showcased a tool which can copy an entire github re…
Backing up a MySQL database running on production is crucial to ensure data integrity and availability. In the event of hardware failures, software bugs, human errors, or malicious attacks, a backup provides a reliable way to restore lo…
Over the weekend I was bored and tried hosting node applications on IIS on a server. Since currently I have only tried wordpress I had no idea how to go about this which might be why you are here, so lets dive straight into how to get i…
Recently, I was tasked with building a Chrome extension that scrapes LinkedIn profiles to gather important information such as name, bio, location, follower count, and connection count from a list of predetermined URLs. Once collected,…
A while back, Prakriti and I participated in Women Techies, a hackathon at our university organized by the Google Developer Student Clubs at VIT Vellore. Our goal was simple: reach the final pitches and present on stage. Our journey beg…
The serial port is like a digital messenger that electronic devices use to share information. If you have ever workeded with an Arduino or Raspberry Pi, you may know that we create a serial connection, and begin sending information over…
Following up on the previous article where we discussed what RESTful APIs are and how to create one in python using Django, in this article we will go over how to create a connection with a MySQL database and then perform crud operation…
The concept of APIs is pretty fascinating when starting to code, because it allows us to integrate stuff into our projects which we would not want to develop ourselves. An API in short is just an interface for software applications to c…
In this article, we will guide you through the crucial initial steps of setting up your development environment specifically tailored for Node.js, Express.js, and MySQL. By the end of this tutorial, you'll have a well-configured environ…
Sorting algorithms are precision-driven. Among all the effective and efficient sorting algorithms exists a highly inefficient and unconventional sorting algorithm - Bogo Sort. Instead of relying on strategic computation it relies on a g…
In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution. This is the wikipedia definition. Let us try to further…
Concurrency and Parallelism are both concepts which are used in multithreading. Concurrency refers to the sequential completion of small pieces of multiple tasks such that over a period of time both of them are completed. This means tha…
In the previous article we saw how we can implement basic multithreading in java. However to design efficient and reliable systems using multithreading we need to understand concepts pertaining to the topic of concurrency to actually bu…
Synchronization allows for only one thread to access a piece of code or an object at any given moment. This prevents simultaneous requests to access the data by multiple threads. It is a mechanism put in place to control access to te re…
Multithreading is a way for us to execute the same process across multiple threads. A thread can be understood as a small unit which executes a program/process. A process can be executed by multiple threads at the same time simultaneous…
The most basic approach to this problem would be to iterate over the entire linked list once to find out the length of the list. Then iterate over it again to locate the node to be removed. This can be done in the following way: Let n b…
If we had to reverse the elements of an array we would have to iterate over then entire array and swap the ith element with the (n-i-1)th element where n is the size of the array. Now in a linked list we are not required to swap the dat…
Linked lists are linear data structures, which consist of nodes. These nodes store data in them as well as point to the next node in the list. So each node in the list has 2 attributes, one of the datatype you are trying to store which…
In my third semester at university, I had taken the 'Computer Programming in Java', while learning all the core concepts of java I thought it would be fun to try and make a game in the process. I tried making the snake game! The logic o…
