Introduction

I've received a lot of feedback on my blog posts over the past few months. I'm humbled and grateful for the suggestions, and I always look forward to hearing from readers. You'll often see that I leave my mistakes in the posts along with the corrections, giving credit where …

I like writing programs that run …

C is a fascinating programming language, simple enough to learn in a few days, yet powerful enough to build the world's most complex systems. With its lightweight runtime, C runs everywhere! From microwave ovens to spacecrafts, and everything in between. Sometimes, I can’t help but wonder: Is the universe …

It has been just over five year since the government set in motion to breakup up tech monopolies. It was not a dramatic revolution, but enacting a series of incremental policy updates, revising tax codes, and introducing new guidelines for technology that touches every facet of our lives. Although this …

An easy-sounding “Float to Q1.15” challenge is proposed as an audio FizzBuzz interview question.

Fixed-point arithmetic is central to embedded signal processing where resources and power are often strictly limited. This article explains how Qm.n notation represents numbers with integer and fractional bits, highlighting range and resolution constraints. It discusses the trade-offs between floating-point’s easier development and fixed-point’s hardware cost savings. Examples illustrate clipping, saturation, and rounding techniques for converting between floating and fixed-point. A detailed walk-through of converting Celsius to Fahrenheit in Q10.6 format shows how to preserve precision under hardware constraints. Practical code snippets for FIR and IIR filter implementations in C and Python further demonstrate fixed-point’s capabilities across real-world DSP applications.

Hello! This is my first post. So...

tmp=`mktemp`; gcc -x c -o $tmp - << EOF &> /dev/null && $tmp
#include <stdio.h>
int main() {
  printf("Hello, world!\n");
}
EOF

Which should output:

Hello, world!
