What Is It?

Switching between different programming languages and projects daily can be challenging. To make things easier, I decided to create a quick-access utility for storing and retrieving code snippets, examples, and notes. The new features you learn from various frameworks are often useful later—if not for yourself, then for your coworkers. While Googling is an option, it often takes up valuable time. My solution? A small utility that lets you access your notes in less than 2-3 seconds.

Recently, I’ve been working extensively with PostgreSQL, so I decided to build this tool using this reliable open-source database.

What Can It Do?

This utility allows you to quickly search for syntax examples across multiple programming languages. It’s designed to help you find what you need with minimal effort.

How Does It Work?

The utility is command-line-based and currently supports space-separated search terms. Here’s how it works:

  1. Command Line Interface: You enter your search directly into the terminal.
  2. Space-Separated Keywords: The utility searches for each word you input, using spaces as delimiters.
  3. Language-Specific Searches: The first word in your query specifies the programming language, while the remaining words are used to search within that language's notes.

Example

For instance, if you type:

php string length

The utility understands "php" as the programming language and searches for examples related to string length in PHP.

Although the original link to try the utility no longer works due to the website migration to Blogger.com, the concept and potential of the tool remain the same.

Play table

Using proximity sensors for playing midi tones combined with LED visualization Description The goal of this project was to create a table-sized device equipped with multiple proximity sensors capable of playing MIDI tones. Each sensor is accompanied by LEDs that indicate the distance of the user's hand above the table. This interactive table can be used by one or more people simultaneously. Hardware Setup I began with a cardboard prototype to test the sensors and the underlying logic. Afterward, I ordered a custom plottered sticker with a design which was painted with bare conductive paint. I drilled holes and connected the touchboard to seven Arduino Nanos, each controlling 13 LEDs. Additionally, I incorporated two potentiometers: one for volume control and another for changing the note setup. Programming The programming task was divided into two parts: Master Program (Touchboard): Reads values from the proximity sensors and sends messages to the slave Arduinos. Sl

Skate Tricks Recognition Using Gyroscope

Image
In this article, we’ll describe how to recognize skateboard tricks using a gyroscope. This sensor is already present in most smartphones, but if you’re not familiar with it, here is a description . Before we dive in, a small disclaimer: This project originated as part of a Slido hackathon with the goal of demonstrating that it’s possible to recognize skateboard tricks using a gyroscope. For simplicity, we’ll focus on recognizing just two basic tricks and won’t consider the skater’s stance on the board. We’ll break down the problem into several smaller tasks: recording the trick, storing the data, describing the trick, analyzing it, and, finally, recognizing it. Recording the Trick Let’s start with trick recording. To obtain precise data, the device with the gyroscope needs to be attached directly to the skateboard. Place it on the bottom of the board to avoid interfering with the execution of the trick. The device should also be compact and lightweight to avoid altering the board’s cen

Counting dice and train wagons using computer vision

Computer vision exercises with preprocessing Before starting my next project, I decided to work on some computer vision exercises. Each example is based on straightforward image preprocessing techniques. No complex data structures or machine learning are involved. Dice Detection I got this idea while browsing the net and became curious about how challenging it would be to write such a script. Here’s a step-by-step breakdown of the algorithm: Movement Detection : By comparing several frames with thresholds, we can determine if there is any movement in the frame. Adding a small time buffer after the movement stops gives us more accurate information. Removing the Background : Thresholding the grayscale frame helps to remove the background, leaving us with a binary image that highlights the objects. Cropping the Objects : Using contours, we can detect and isolate the objects by cropping them. Detecting Dots : By inverting the image, the dots on the dice become more distinguish
