A dummy’s guide to Machine Learning

“A breakthrough in machine learning would be worth 10 Microsofts”,said Bill Gates once.

Why would he possibly say something like that? A much-hyped tech jargon or something really mindblowing? What is Machine Learning anyway? Why should I learn it? Will it pave a successful career path for me?
Whoa! So many questions arise when a newbie hears about ML and AI. There are answers to each of the spread across the internet. All you need is to sit and surf through them. But how does one clear all the doubts in one shot? With this, ‘A dummy guide to Machine Learning’. .
WTF is Machine Learning anyway?
Data Sciences, Big Data Analytics, Artificial Intelligence, Predictive Analytics, Computational Statistics… all these fancy words spin around your world? They sure would. So let me put it plain and simple. Machine Learning is about teaching computers how to learn from data to make decisions or predictions. It gives the computer to learn without being explicitly programmed. In short, you teach your computer how to think.
What are the types?
 
They are majorly of three types. The names and examples sum it all.
  • Supervised Learning– You apply rules/filters in your email inbox to directly delete or archive the spam messages from marketing channels.
  • Unsupervised Learning– Your camera automatically detects your face/smile.
  • Reinforced Learning– The self-driven cars having cameras, computer and controllers interacting with the roads and nearby surroundings/obstacles to give you a safe ride.

Why should I learn it?

Are you an Iron Man fan? Do you like Jarvis or not? Yes, you do. Wouldn’t it be cool to build one yourself? It’s a really fun and cool skillset with a huge global demand. Entry salaries start from $100k – $150k. Data scientists, software engineers, and business analysts all benefit by knowing machine learning. Big bucks, lots of fun and innovation, what else do you possibly need?
Are there any prerequisites?
You don’t need to be a pro mathematician or a veteran in programming to learn machine learning but you do need to get the basics right. For starters, a ground knowledge of these three are sufficient:
  • Python for data science
  • Statistics for data science
  • Mathematics for data science

Are there any practical examples of this theory?

 
Yes, there are plenty! In fact all around us. I’ll give you some everyday examples which you can relate to:
  • Notice the recommended products on Amazon and other e-commerce websites? They are all machine learning based recommendation systems. They learn from you- your surfing habits, purchasing behavior, history, and other traceable patterns.
  • Your iPhone opens with your thumbprint, it’s no different!
  • How can we miss out Siri if we talk about the iPhone? Same goes for the google assistant.
  • Tesla Self driven Cars and so much more.

Everything you wished you knew about Ruby on Rails

ruby_blog-01

Airbnb, Scribd, Groupon, Kickstarter, Pitchfork, Soundcloud, Square, Yammer, Crunchbase, Slideshare, Zendesk, Github, and Shopify…. whooof! They all have one thing in common. Can you guess? Well, let me give you a hint here.
 “It’s a breakthrough in lowering the barriers of entry to programming. Powerful web applications that formerly might have taken weeks or months to develop can be produced in a matter of days.  “, says Tim O’ Reily in its honor. Getting intense is it? Let us cut the crap; it is none other than…..

 

Ruby on Rails! 
But what is so good about it? Why is it in the news anyway? Let me take you through a hyperloop journey on why you need to have Ruby on Rails as a skill set today.
The language
The language itself beholds so many surprises for you. It combines some of the best features of dynamic languages. Taking some of the best ideas from strongly typed, static languages and blending them with an object-oriented paradigm makes it super strong. The language has an affinity for getting stuff done with minimal coding. An open source language with a code based model having all the essential elements to make you fall in love with it.
Plenty of online resources and an ever thriving community
 
Lynda.com, Codeacademy, Rails for Zombies, Treehouse, Learn Ruby the Hard Way and much more. A very well-documented language with an ever thriving community. There a thousand of meetups, code jams and hackathons you can go to almost every week. Trust me, all you need is a good dose of Ruby on Rails for the day.
A beginner’s best friend
Ruby is generous, ever forgiving and beginner friendly at every step. You do not need to remember to end your lines with a semicolon (;) or whitespace tabbing. It’s the teacher you always wanted. Forget to open or close the braces? Ruby will forgive you, grant you marks and make you win! You won’t need to know any SQL to use a database in your Ruby on Rails application which is just awesome. It also teaches you the best developmental practices. All in all its the code buddy, you always wanted.
Developer’s joy
 
Rapid developmental model, direct access to HTML, CSS and Javascript, full-stack development are few of the many benefits that developers see in ROR. It also has a wide coverage of vendor support and is gaining great traction across the globe. You may not see a number of job openings on this skill but more and more startups are hiring such developers to do many things at a go. All at lucrative payouts. Increased demand, inadequate supply… #ifyouknowwhatimean then grab the opportunity before it slips.
Such good stuff, I know you’re in awe by now. Don’t wait up, get-set-code and ride the Ruby on Rails with Coding Ninjas today!

logo_square-01
It’s a Ninja world out there! Ninjas are lightning sharp and swift. And with the evolution of programming and programmers, a new breed of coders leveled up. These were the Samurais of the Code World, popularly known as a ‘Code Ninja’. Wondering who is a Code Ninja? Urban dictionary defines it as someone who has excellent knowledge in many programming languages. A Coding Ninjitsu defines the discipline and strategies that a Code Ninja follows for accuracy, speed and power. So here are some characteristics of a kickass coding Ninja:
Bugei (Martial Skills):
Reason_1-01-01
Great technical skills are the primary weapons or the Buki of a coding Ninja. He/She is not afraid of whatever comes in the way and ready to tackle it all. Years of experience and adding new languages to the stack from time to time builds up a master Ninja.
Willingness to learn:
Reason_2-01The school of learning (Kogaku) should always be resident in a Coding Ninja’s heart. Technology is always evolving and the skills and abilities of a coder need to be revised from time to time. It’s important that a coder has an interest in following the latest trends and is eager to participate in any continuing education opportunities that are available.
Aikijujutsu (Combative grappling):
Reason_3-01
Creating code is only part of the job, debugging is an important aspect. When the code doesn’t work as expected, a coder is expected to get to the root of the problem and fix it effectively.  A true coding Ninja prefers to carefully investigate his code and research possible issues until an answer is found instead of aimlessly editing the code.
Hensogakurejutsu (The art of blending): 
Reason_4-01
Some programmers require complete silence to concentrate, while others thrive in chaos. A true coding Ninja can thrive in any conditions to complete his errand.
Gowaza (Problem Solving/Hard Fighting skills):

5 kickass reasons why you should start learning Android Development today!

‘Google’
It’s not just a name but an experience. An experience that touched and changed our lives forever. Almost a decade ago, google launched this wonderful OS called ‘Android’ which redefined mobile experience forever.  An Android revolution had begun. And today?
With over 1.4billion active users in the world, it captures 87.5% of the total market share of global mobile operating system. The beauty of the OS lies in it being an open source operating system. That means it gives the leisure to use, or add, or even modify the source code depending on the needs of an individual/company. Today android powers billions of devices and is changing the mobile application industry inexplicably. Android development is one of the most sought after skills of 2017 and has been ruling the charts.
So why should you have an android developer badge up your shirt? Let us give you 5 solid reasons and you’ll know why.
1. You’ll fall in love with it, no doubts about that!
I have reasons when I make such a bold statement. Firstly android is an open source platform i.e.- that you are free to develop an app and deploy its prototype without spending a single penny! Then the ease of access, development and deployment make it a developer’s favorite. There is an insane amount of Android support available online at no cost. You can actually be a self-taught developer and make bucks out of it.
2. It’s an ever-growing market
 
Like dense Amazonian rain forests, the canopy of android is never ending. And when I say that, it’s both in terms of opportunities and ideas. The online Android community welcomes beginners with open arms. Want to know the number game? Here let’s take a look at them:
  • Over 1.5 million Android devices are activated across the globe every day.
  • There are over 2.2 million apps in Google Play store & growing!
  • Over 60% of Android apps are for free!
3. World’s largest app market to deploy and monetize your apps:
 
Every since Google’s Playstore came into existence, the joy of experiencing the apps has multiplied tenfold! Google pays millions of dollars every year to Android Developers. If you come up with something that becomes popular and sells really well, the monetization properties are endless. Let’s say you make a ‘hip and popular’ app and 0.001% of the android users download your app. Firstly, let me tell you there are over 60 million android users in India alone. So that makes it a total of 60,000 downloads and you price your app as low as 20 Rs.
Do the math, 60,000 * 20 = a whopping INR 1.2 million!
This and more with just 0.001% downloads in India alone! Even if your apps are free you can always earn through ads.
4. Job prospects and freedom
 
Today, business/brands want to reach out to their customers. Whether a profit or a non-profit organization, every company owns an app or are in the process of getting one. The demand for app developers is increasing at an exponential rate globally. The unique advantage of learning app development is that you can choose to work full-time or freelance. It gives you freedom and the right to choose to work for yourself or somebody else. Empowerment, freedom, and money! What else do you possibly need?
5. Sharp learning curve
There is no denying of the fact that Android is everywhere. Different devices mean different opportunities to learn and explore. Java and XML are the bare basics and it scales higher up as you proceed. There are endless opportunities to explore with Android which iOS doesn’t allow you to do. And the simplicity of the language gets you rollin’.
But self-learning seems too much of a work eh? Thomas Edison once said, ” Opportunity is missed by most people because it is dressed in overalls and seems like work.” But wait, this one is already shouting out loud, so attend our Droid-it Android Workshop and get kickstarted into Android development!
Get-set-droid-it!
