Has your Python application been running a bit slow lately? We’ve all been there! Luckily, continuous profiling can help you catch those sneaky performance issues before they slow everything down. It’s like having a constant health check for your code. In this blog, we’ll explain how continuous profiling works—and why it’s a game-changer for keeping your Python apps fast and …
Though we don’t really see as many of them as we used to, they are still with us. One helps indicate if a 10-key is in number or cursor mode. Another helps show when we use capital letters without holding the shift key. You might even have another to show if you accidentally hit the scroll lock key. I’m talking of course about keyboard state indicators.
Most people only think of a keyboard as an output device, but given that it has a changeable state, it most definitely can be used for output as well! Unfortunately, producing meaningful output using a keyboard state indicator (beyond their intended purpose) is rather tedious because they only have two states; the indicator light is either on or off. And to convolute things further, most keyboards these days don’t have many indicators in general. For example, the very keyboard I’m typing on only has a caps lock indicator! Thankfully, there is a well-established encoding that requires only one “bit” to be useful: Morse code!
In this article, I will show how I approached the development of a small utility to output Morse code on the caps lock LED. Even if it’s impractical, I wanted a challenge, and I had fun working through it. Though I’m certainly not an expert, I used the C programming language because I figured it would be the simplest approach.
I hope it is as clear to you, the reader, as it is to me, especially since I tried to make this as simple as possible. And don’t worry if you don’t have a caps lock indicator, either, as we will display the Morse code, too.
