Hi everyone I have been working on a sports analytics startup and the whole front-end is made using React. I haven’t had to work on such a big React project before this and so it brought along some unique challenges. In the past, SEO hasn’t been a big issue for the web projects I have worked...

Hi everyone I was working on a React project these last couple of weeks and I had to implement login functionality. I searched around and most of the solutions I found relied on Redux or some other huge dependency that I wasn’t already using in my project. I didn’t want to introduce a big...

Hi everyone In my book (Practical Python Projects), I initially had a section showing the readers how to upload stories on Instagram in an automated fashion. I ended up removing the code from the last draft of the book for various reasons. During the span of a few months, the library I was...

Hi everyone Remember I wrote a post recently about how you can listen to your local police department using a Baofeng? As it turns out, most police and fire departments have moved to trunked radio. Trunked radio is just a fancy way of saying that these departments have gone digital. A Baofeng...

Hi everyone I have big news The alpha version of my Practical Python Projects book is out It took me two years and countless hours to get to this stage and I am so proud of it. You can buy it now at Feldroy.com. The final version of the book will be more expensive than the alpha price of 29...

Hi lovely people I am a huge radio enthusiast. So much so that I recently gave (and cleared) my Technician Ham license exam. I am now just waiting for my call sign to appear in the FCC database. While that is happening, I went ahead and bought a BaoFeng UV-5X3 radio. Note: If you ever decide...

Hi everyone Today we are going to understand the JPEG compression algorithm. One thing a lot of people don’t know is that JPEG is not a format but rather an algorithm. The JPEG images you see are mostly in the JFIF format (JPEG File Interchange Format) that internally uses the JPEG compression...

Hi everyone If you have been following my blog then you might have already read the article on reverse engineering an Android app by writing custom smali code. I am still very much a reverse engineering beginner so after that article, I got to learn about Frida. I was told that Frida is much...

I had always wanted to learn how to reverse engineer Android apps. There were people out there who knew how to navigate and modify the internals of an APK file and I wasn’t one of them. This had to be changed but it took a long time for that to happen. In this post, I will show you how I was able...

Have you ever been to a coffee shop and tried connecting to the public WiFi only to find out that your browser isn’t automatically opening up the router login page? These situations suck and happen far too often with all of us. I recently got a new Linux based machine and Firefox wasn’t...

Hi everyone Lately I have been restructuring my online presence and that included running this blog using a static site generator. During this process, I decided to also look for privacy-preserving Google Analytics alternatives. When concerned with website analytics, the default solution most...

During my day to day work, I have had to do a lot of scripting. This can range from running short tests in Docker containers to running super long processes in Azure Batch service. I have used Bash and Python for these purposes and learned quite a few useful techniques along the way. I am sharing...

Hi everyone I maintain an old website for a client that was originally developed in 2015. It hasn’t been updated for the last 5 years and uses Django 1.7 and some Django extensions which haven’t been updated for Django 3. I recently decided to move the website to a new server and had to...

Hi lovely people A couple of months ago I wrote a couple of articles on how to connect different sensors and an LCD to an Arduino. However, I didn’t write one final article about how these things all fit together to form a greenhouse monitoring system. I don’t think I will be able to get to it...

Hi everyone This past summer I interned at ASAPP. I had an amazing time and learned quite a lot. I worked with Docker, Kubernetes, Kafka, Redis, Rabbit MQ, Golang, react and typescript. I was a part of the routing team and spent most of my time on implementing new features. This often meant...

Hi people This post is about how to set up email notifications for new comments on your blog using staticman. This way if someone posts a comment on an article can automatically get updated in case someone else makes a new comment on the same article. It took me a while to figure out how to do...

Hi everyone After transitioning to a static blog website, I had one problem. My blog no longer had comments functionality. Yes, I could have used Disqus but I personally hate it. It is bloated with a lot of unwanted code. I did some search a while ago but couldn’t find anything. I did a more...

Hi everyone I got an email from someone pretty recently who wanted to setup a dev environment for SciPy. He had made changes to the source code of SciPy and now wanted to test if his changes were working or not. He had gotten so far without actually testing the code. In this post I will share...

Hi lovely people A lot of times we end up writing code in Python which does remote requests or reads multiple files or does processing on some data. And in a lot of those cases I have seen programmers using a simple for loop which takes forever to finish executing. For example: import requests...

Running Python in the web browser has been getting a lot of attention lately. Shaun Taylor-Morgan knows what he’s talking about here - he works for Anvil, a full-featured application platform for writing full-stack web apps with nothing but Python. So I invited him to give us an overview and...

Hi lovely people As part of a research I am doing I had to write some bash scripts which were supposed to run every couple of minutes. I made some embarrassing mistakes along the way. I will write about those mistakes in hopes that you don’t make them if and when you write your own bash...

Hi lovely people In the last two posts, we learned how to use the temperature, light intensity, and soil moisture sensors. So far we have covered all of the sensors my greenhouse is going to have in the alpha version. I know I am missing out on the integral humidity sensor but I didn’t have...

Hi lovely people In the last article we talked about the soil moisture sensor. In this article, we will take a look at how to measure temperature using DS18b20 and measure light intensity using a photocell. Step 1: Wiring up the Circuit We will be using: Arduino UNO Breadboard DS18B20...

Hi lovely people If you have read any of my other articles you might be aware that I am working with electronics right now. After learning the basics of Arduino, I decided to work on a relatively ambitious project. I decided to make a greenhouse monitoring system. I am going to write a series...

Hi lovely people I am working on a greenhouse monitoring project and I had to connect my Arduino to the internet over WiFi. I wanted to push some sensor data to my server. I could have bought a WiFi shield for the Arduino but why spend more money when you already have a Pi with WiFi card? I...

Hi people If you read the last article you might be aware that I am exploring raspberry pi right now. I have Pi 3B and I am using it to work on some remote sensors. The biggest issue I have with the Pi is that I don’t have an external monitor, mouse, and keyboard handy to use with the Pi. I...

Hi people I was working with Raspberry Pi lately and was trying to connect it to eduroam. If you are not familiar with eduroam, it is a service used by most universities to provide Wifi on their campuses. It uses Enterprise WPA and Raspberry Pi does not connect to it automatically out of the...

I had already seen the video about the History of Unix by Rob Pike (do watch it if this kind of stuff interests you. It is available on YouTube) so I didn’t think I would learn a lot of new stuff from this movie but oh boy was I wrong. This was an interesting deep dive into the history of the GNU...
