"When Will It Be Done?" - A Fun Yet Realistic Guide to Estimating Software Project Timelines

By mvryo
Ah, the age-old question asked by managers, clients, and product owners alike… usually right after you’ve just finished reading the project brief. The answer? “It depends” — followed by awkward silence and maybe a nervous laugh. Whether you’re team Waterfall or team Agile , one thing’s for sure: estimating timelines is part art, part science, and part hoping no one adds features mid-sprint.   Let’s dive into how to properly estimate software project timelines — and avoid the infamous “We thought it’d take 2 weeks but it took 3 months” situation. 1. Understand the Scope (No, Really. Understand it.) Common mistake:  You’re told, “It’s just a simple login page,” and you estimate half a day. Turns out they want: Email/password + Google/Facebook login OTP verification Password strength meter Dark mode And it has to work on a smart fridge. Pro tip: Before estimating anything, get a detailed list of requirements . If they say, “We’ll finalize the features later,” your response shou...

By mvryo
If you’ve seen version numbers like   1.2.3  or  4.5.6-beta , and wondered what all those numbers mean — you're in the right place. This is your  no-jargon ,  easy-to-digest  guide to  Semantic Versioning  — or  SemVer . What is Semantic Versioning? Semantic Versioning is a standard for naming versions of your software. It uses three numbers: MAJOR.MINOR.PATCH Basic Format 1.2.3 ↑ ↑ ↑ │ │ └─ PATCH │ └─── MINOR └───── MAJOR Now let’s break it down —  as if you’re explaining it to your non-techy cousin. The Numbers 1. MAJOR version ( 1.x.x ) When you  break things . Not compatible with old versions. You remove or change a function’s behavior in a way that older code will break. Example : You go from   1.2.3   ➜   2.0.0 "Whoa, we broke something!" 2. MINOR version ( x.1.x ) When you  add features , but nothing breaks. Compatible with old versions. Example: You go from   1.2.3   ➜   1.3.0 "Hey, we adde...

Understanding Recursion in C: A Beginner-Friendly Guide

By mvryo
If you’ve just started learning about recursion in your programming course, it might feel a little confusing at first. But don’t worry — in this guide, we’ll break it down into small, easy-to-digest pieces with sample C codes and clear explanations. By the end, you’ll understand   what recursion is ,   how it works , and   when to use it . Tip:  You can try out all the code examples in this article using an online compiler like  Programiz Online C Compiler . No installation needed! What is Recursion? Recursion  is a programming technique where a function  calls itself  to solve smaller parts of a problem until it reaches a simple case (called the  base case ). Think of recursion like solving a puzzle where each piece depends on solving a smaller puzzle first. Key Concepts Recursive function  — a function that calls itself. Base case  — the condition that stops the recursion. Recursive case  — the part of the function where it c...
