Big-O Ambiguity

Dzone - 1 hour 13 sec ago

Back to University

Most people talk about Big-O notation when it comes to runtime and space complexity. But when you recall your first year at university, most probably you had an Algorithm and Data Structure course when you have learned not only Big-O notation, but also Big-Ω (Omega) and Big-Θ (Theta). Here is a very brief definition:

  • if f(n) is O(g(n)), it means that f(n) grows asymptotically no faster than g(n)
  • if f(n) is Ω(g(n)), it means that f(n) grows asymptotically no slower than g(n)
  • if f(n) is Θ(g(n)), it means that f(n) grows asymptotically at the same rate as g(n) 

In other words, O(g(n)) is an upper bound which means that from certain point (n0 on the graph below), c*g(n) is never below the function f(n) which we are analyzing (don’t worry about c — it is just a constant).

When a REST Resource Should Get Its Own Address

Dzone - 1 hour 30 sec ago

Background

Author's note

In a purist REST approach, all endpoints (except the starting endpoint) are opaque and their various details shouldn't need to be published. Even if this approach is being used, the points in this article are relevant as Server logic will have to determine when something requires an endpoint or not.

A Brief Overview of Swift Compiler

Dzone - 1 hour 41 sec ago

Apple's open-sourced Swift programming language and its whole source code are now available on GitHub. There are thousands of programming languages available in the world and hundreds on the way, but the underlying basics of programming languages remains the same. It's very important to understand the roots so that you can learn programming languages easily. The languages are either compiled or interpreted. You can read the difference between them here. An interpreted language takes input and produces output directly, however, compiled languages first prepare executables and then, according to the data, they produce output.

Swift is a compiled language, meaning before producing the actual output, Swift performs various activities. These activities are generally performed by the Swift compiler. In this post, we will see a brief overview of the Swift compiler.

5 Success Stories That Will Make You Believe in Scaled Agile

Dzone - 1 hour 42 sec ago

Taking your company from Waterfall to Agile isn’t a trivial task. And it begins to look more like a “mission impossible” if we’re talking about large enterprises that have dozens of teams working towards a common goal.

Below we present five case studies that demonstrate just that—that scaling Agile is not only possible, but can also yield great benefits. We hope you’ll learn something new from these examples!

CRUD Operations in IndexedDB Using JsStore

Dzone - 1 hour 42 sec ago

IndexedDB is a database technology to store data in browsers. The problem is that it is too complex, even for simple cases, so most developers don't use it.

I was struggling with the same situation but I had to use it in one of my projects. I found an awesome library called JsStore that makes IndexedDB look like SQL and simpler than you can imagine. Then, I thought about efficiency and all. I researched a little and found that it executes the query in the web worker and handles everything for you.
