21 of the best free resources to learn SQL

I self-taught myself SQL after I bombed a technical interview that involved SQL. It got me a bit mad at myself, so I went ahead and started looking for different resources to help me practice and learn SQL. I wasn’t looking to spend any money so I focused on getting the best free resources. The list below is the fruit of my efforts. I hope that it helps you on your journey to learn SQL.

It can be handy to learn SQL. You might be looking to do data analysis with it, or you might look to learn SQL to help answer different questions you have on your data. A quarter of data users use MySQL databases — to get access, you’ll need to learn SQL.


1- Codeacademy

Codeacademy is one of my go-to resources for learning programming because it involves interactive exercises where you get immediate feedback. This is what makes the practice and learning of programming so fluid and rapid. Their section on SQL meets the same bar as the rest of their courses, and of course, it’s free.

2- Stanford Databases Mini-Course

This free self-paced mini-lesson on databases and SQL allows you to follow along with what top computer science students at Stanford are learning — all this at a self-directed pace, and for the total cost of zero dollars.

3- Head-First SQL (O’Reilly)

This book by O’Reilly entitled SQL Head First helps you dive deep into SQL topics, with tons of examples and writing to help you learn SQL. It can be completely free with a free trial of their Safari product (though the trial will run out). I classified it as a free resource as it doesn’t seem like O’Reilly’s paywalled it.

4- SQL Tutorial – W3Schools

W3Schools offers a text + exercises tutorial that breaks down individual SQL functions. I like looking through individual-level examples of different functions, especially when I’ve forgotten the nuances of one or another. You’ll see that several other providers do the same thing as W3Schools, but for me, W3 is the best resource out of the lot.

5- SQLZoo

SQLZoo is one of the coolest free SQL resources out there. The set of rich, interactive exercises placed in real-world settings is about as close as you’ll get to working with SQL in complex production-level environments without actually being hired. I used it a lot to practice SQL as I was picking up data analysis skills and I still use it every once in a while as a refresher.

6- Mode Analytics

Mode Analytics offers a cool, intuitive interface along with a case study like approach involving Crunchbase data. It can help you rapidly place your SQL skills in a context that is like real-world uses, and once again, it’s free. They’re trying to upsell you to their paid product in offering this educational resource. That type of content always does well however, because it’s never priced and the focus of the team in question is to deliver maximum quality and substance for your learning objectives.

7- Sololearn 

This Sololearn course is interesting because it has different quizzes to make sure you retain material as you’re learning it. It follows the same conventional structure of teaching you how to select and query data, then teaching you how to sort and manipulate it within a data table, finally moving to joining and modifying tables. Notably, there isn’t much here in the way of aggregation functions or subqueries, which other courses above will teach.

8- SQL for Beginners (Youtube)

If you prefer learning with video content, this 1-hour video tutorial on SQL might just do the trick for you. It starts going over the basics of SQL, then shifts into the end by talking through different functions and examples on video. It is however meant to be an introduction — don’t expect to become an expert in SQL just by watching this video.

9- SQL Tutorial

SQL Tutorial offers an interface like W3Schools without the exercises. In case none of the resources above it seem to be working for you, this is another free resource where you can break down and learn SQL functions one-by-one.

10- SQLCourse

SQLCourse offers a curriculum with specific exercises for different functions. It is another handy way to practice your SQL skills for free. The interface is a bit janky, but it’s workable.

11- Welcome to SQL (KhanAcademy)

If you prefer a set of curated video tutorials that cover different topics, then look no further than the KhanAcademy course that introduces SQL. It runs through to the basics until aggregating data — there are projects in between as well. If you’re already on KhanAcademy, this could be a perfect transition to you learning SQL.

12-TutorialsPoint

Yet another text + examples format of teaching SQL, TutorialsPoint does offer more of the same: but if you’re looking for more and more practice or different ways to digest SQL material, it might be handy enough for you.

13- SQLBolt 

SQLBolt is constructed a bit like a virtual, interactive book on SQL. You can read through it and then go through each exercise, feeling like you’re being guided on your journey by the book-like structure. If you want a more focused and curated approach to learning SQL — this might be it for you.

 

14- Galaxql

Another interactive SQL course, meant to run in the browser. It’s free-to-use, but may use quite a few intensive resources as it’s running. (not sure if that’s just how old this tutorial is, or an honest warning). It is free to try if you want to take a look.

15- Use the Index 

Use the Index is a very useful advanced training site for SQL. Once you have the basics down, check out this site to see how to optimize your SQL databases and your queries so you can get maximum performance from it.

16 – Schemaverse 

Schemaverse is a game built entirely on SQL. I’m a big fan of using gaming to motivate people to learn. I think it could show an exponential effect on motivation and on acquiring SQL skills if you’re somebody who wants to learn, but might get bored out of their mind with conventional tutorials or videos.

17- SQL Server Microsoft Documentation

The Microsoft documentation around SQL Server can help you understand how to use their software to manage SQL databases and tables — it’s offered for free, so you can take advantage and have a look even if you’re just curious.

18- SQLFiddle

SQLFiddle allows you to upload data and play around with different SQL queries to see what data comes back. It is a great way to practice your SQL skills, especially if you don’t have a real-world database to play with. You can take .sql files from elsewhere, upload them, and then try to manipulate the data contained within or query certain selections of data. It is also free to use — which never hurts.

19- MySQL Sandbox

MySQL sandbox allows you to install several MySQL servers in sandbox mode, allowing you to rapidly experiment, test and learn with different data files. It can be a useful way for you to practice what you can do with multiple SQL instances.

20- Stack Overflow (SQL) 

One of my favorite free resources to learn SQL or really any programming language is StackOverflow. This is an online Q&A community focused on technical topics where you can ask experts questions or see solutions to existing problems. It’s a fantastic community to immerse yourself in if you’re learning SQL. The specific SQL tag makes sure that you can stay focused on SQL topics.

21- r/LearnSQL (Reddit)

Another great community for learning is Reddit — where you can see different resources being placed and ranked by users as the days go by. Take part in discussions here or take advantage of articles or discussions posted to spur your own learning exponentially forward.


Hopefully, all these free resources are helpful to you on your journey to learn SQL — they were helpful to me as I started learning. While I leaned on some a bit more than others, I’m always a big fan of curating as many resources as possible because my learning style (very text-heavy) may not be the same as yours.

A lot of research has been done on the predictive abilities of matching how a concept is presented with a preferred learning style. While few models meet the test, it does seem like digesting new materials under a whole bunch of different modes or media formats helps learning.

So if you want to learn SQL, it’s best to go through and try a few of these resources, then choosing and sticking to which ones you like and combating the learning problem from many different angles.

Nine Free Resources to Learn Solidity

If you’re here, it’s likely because you’ve heard about Solidity and blockchain development. You’re probably looking to get involved and build your own DApps and you’re looking to learn solidity. This resource is the perfect place to get you started if that’s the case.

First let’s stop off with a primer about Solidity: the what of it, the why, and then what of what you can build with it. If you want to skip ahead to the resources, feel free to click here.

What is Solidity?

learn solidity

We have to start here with the concept of blockchains, immutable, distributed datastores that are verified by a network of actors rather than one centralized source. Bitcoin is the most famous example of this technology and its first widely adopted application.

The genesis of Solidity comes from the simple realization that while Bitcoin is a highly secure blockchain, it was not very scalable both from a technical sense, but also from a community development sense: people had to either create entire new blockchains or fork into the existing chain to create new innovations or iterations.

Solidity is the programming language associated with Ethereum, a blockchain that aimed to have developers iterate on top of it: the Ethereum blockchain aimed to provide a more complete platform where developers could dictate more of the logic behind what data and payments get recorded on the blockchain, and which do not. Solidity is the programming tool that makes that possible.

Ethereum rests on the principle of decentralization: as with other blockchains, there is no centralized data storage that declares a certain state for the entire system. Data and the state of the system flow through a series of decentralized nodes that can be run on a number of different servers. For example, you could run an Ethereum node on your PC, and it would form part of a collective amount of computing power dedicated to sending and verifying data on the Ethereum blockchain.

In technical terms, the Solidity language is Turing complete (meaning that it is a general-purpose programming language similar in functionality to JavaScript and that you can program for loops, if statements and more and benefit from object inheritance and function modifiers), and it’s a contract-based language oriented around Python, JavaScript and C++ concepts meant to be executed on the Ethereum Virtual Machine. It is a high-level language that abstracts away many fundamental memory and space problems so as to allow programmers to easily build their own DApps.  

Why Solidity?

learn solidity

Solidity is a language that compiles with the Ethereum Virtual Machine within each Ethereum node — you can think of the EVM as a Solidity compiler. It comes with a set of conventions and global variables (such as msg.sender, indicating an Ethereum address that triggers a function) that can make your life easier, and it’s easily plugged into web3.js, an API that allows you to interact with common JavaScript web frameworks such as React.js. It is, in short, the easiest way for you to create Ethereum wallets and embed them in your apps (allowing you the ability to transact monetary value in your functions).

While there are other Ethereum programming languages (such as the more Python-based Serpent), Solidity is the most popular one with the most documentation out there so far. You’ll be able to access complementary libraries such as those offered by OpenZeppelin and utility tools such as Truffle.  If you want to build something with Ethereum, or you want to monetize your functions or build your own token, you’re probably going to end up using Solidity.

What can you build with Solidity?

learn solidity

You might have heard of smart contracts — you’ll be able to build smart contracts that execute different functions with Solidity. This will allow you to write data to the Ethereum blockchain or to receive or send Ether when people trigger different functions. Think of it as integrating a wallet directly in your code.

An interesting limitation you’ll have to deal with is that function calls are correlated to gas price within the Ethereum blockchain, meaning people will pay to execute functions on your platform. This is something you’ll have to keep in mind as you scale out new applications — the monetization of your functions can be a double-edged sword.

Onto real-life examples, you can build your own token according to the ERC-20 standard and start distributing it for initial coin offerings. You can create your own game that might go viral (such as CryptoKitties). You could even create your own decentralized exchange for buying and selling other tokens such as the people behind Etherdelta have done. You can build any number of Ethereum Dapps. The possibilities are there for you to explore once you understand the technology.

Ok, what are the nine resources you promised?

Fair is fair. If you’ve made it this far or clicked through all the way down to the bottom, you’re probably looking for the resources I promised you to help you learn Solidity and different Solidity tutorials. 

Here they are, in the order for which I think it makes sense for you to consult them.

1. ConSensys Resources

You’ll want to start off with a general overview of Ethereum, different blockchain concepts, and a feel for how Solidity can fit into that framework. This compilation of resources can certainly be helpful in that space and help flesh out the context of the space you’re getting into when you start building smart contracts. You’ll be able to see and get inspired by the vast potential of what has been done with smart contracts — and what you can do with them in turn.

2. How to set up an Ethereum Node

Next up, you’ll want to set up an Ethereum node yourself. This is useful for local testing of the apps you build but also, in a greater sense, provides you with the bridge you need to be part of the Ethereum community. The guide in question links out to a section where you can install an Ethereum node under different operating systems — it also contains sections dedicated to other aspects of Ethereum you may find interesting, including the mining mechanism for it.

3. Ethereum for Web Developers

This guide on Ethereum concepts can help you really understand the promise of Solidity and how you can extrapolate your thinking about web concepts into development for blockchain.

It also allows you to separate out the differences between centralized and decentralized datastores and how you should conceptually think about the programming logic for either.

The guide then moves onto a free tutorial (though the rest of the site offers paid lessons) on how to build a ballot voting system in Solidity that is much better than any “Hello World” tutorial could be in terms of getting you started on your path to learning Solidity.

4. BlockGeeks Guide to Solidity

This guide offers you yet another text-based case study for creating something in Solidity — this time though, you’ll be able to get an overview of how to build a web app in conjunction with Ethereum functionality.

Think of this as a case study upon which you can layer the Solidity concepts you’re learning and put them into practice. It will also teach you how to build a development environment for Solidity apps so that you can build your own smart contract and iterate on it in real-time without the fear of breaking anything as you learn Solidity.

5. Smart Contracts Best Practices

This resource from ConsenSys, an accelerator based on powering different teams working on Ethereum-based projects helps you define more of the meta-thinking behind Ethereum smart-contracts.

It will help you design smart contracts and tailor your learning around best practices that will keep your contracts performant and secure as you learn Solidity — highly desirable factors in an emerging tech ecosystem that is often in flux.

6. CryptoZombies

This handy game helps explain Ethereum functions in more depth and will help you learn Solidity — you can learn interactively by building your own version of CryptoKitties (CryptoZombies) — as you go through, you’ll be able to explore, among other things, function creation, function calls and modification, how to implement standard programming language such as assert and if statements, the different data types within Solidity, how to make objects inherit from one another, how to return data and finally, how to determine who can securely access and trigger different functions within your code.

7. YouTube Intro to Solidity

If you’re more of a visual learner rather than textual, you’ll find this video series on YouTube more amenable to your desire to learn Solidity.

Use it to catch up on Solidity concepts or to refresh your knowledge — or try this learning perspective first if you know a video is how you learn best.

8. Remix for Ethereum

With this web browser based compiler for Solidity code, you can experiment with different contracts and different functions cheaply, seeing what compiles properly and what doesn’t right off the bat. It’s a great, experimental way for you to learn Solidity and practice with it.

Consider it a fun sandbox for you to test different functions, similar to what JSFiddle provides for JavaScript, and your first line of validation and defense against improperly built code. It can also serve as the easiest way for you to experiment and build things in a sandbox setting you might not want to deploy.

9. Ethereum StackExchange

Finally, the last resource is the Stack Exchange forum for Ethereum and Solidity questions — a solid resource for you to consult and to pose questions as you’re stumbling around as a beginner, and a community you can give back to once you’ve practiced and built different things with Solidity.

I hope this guide is helpful to getting you started in your Solidity programming journey. If you want to join a newsletter packed with cutting-edge resources for how to learn new technology skills and maximally leverage them for a meaningful and socially impactful life, look no further than mine.

32 Free Tech Job Boards for Programming Job Seekers

If you’re here, it’s because you’re likely looking for a job in technology. This excerpt from our upcoming guide to how to get a programming job without a degree will help you do just that by giving you categories of tech job resources, tech job boards and tech job sites to consult. I’ve helped isolate some of the best job boards for you among the many tech job boards out there. Hopefully, this resource will help you land a new job! 

General

tech job boards

The following tech job boards often have a selection of general jobs, but they are also useful resources that can be used to find technical jobs — if you’re able to process the information correctly. Tech companies abound on these general resources. 

LinkedIn

Sometimes it’s good to start at the most obvious place: LinkedIn has a large number of technology jobs that you can find quite easily. You can sign up for a free trial of the premium version and quickly look through different jobs.

LinkedIn can also be a great way to research hiring managers and get a sense of what a company is like before you even apply there. You’ll be able to see what the organizational hierarchy looks like by scrolling from one profile to another — and you’ll be able to see what skills the company emphasizes, either by looking at the profiles of those who were hired or by using your trial Premium account and looking at job postings or company pages.

You’ll want to think about how to optimize your LinkedIn profile so you can get the most out of this career-oriented social network. Among tech job boards, it is easily one of the largest. 

Crunchboard

Crunchboard is the job board associated with TechCrunch, a publication that specializes in writing about emerging technologies and new companies. As you can imagine, their job board is filled with a lot of technology and web development positions due to their audience.

Another technique you can use related to this is to look for startups that have just raised a large fundraising round on either TechCrunch or CrunchBase and reach out to hiring managers or executives at those companies: immediately after raising a fundraising round, a company is in aggressive growth mode, and is most likely looking to hire many qualified people to fill different and interesting job roles.

Hacker News

Besides being a great repository of technical articles and a community that curates people who are interested in the cutting edge of technology, Hacker News also serves as a job portal of sorts for Y Combinator companies — technology companies that might be as young as a two-person startup and also those who have started full maturing (as an example, Dropbox, Airbnb, and Quora were all at one time or another incubated by Y Combinator). The jobs section of the site features different YC companies and their hiring needs. There are also monthly threads started by a bot called Ask HN: Who is hiring? –where discussion about urgent job opportunities is surfaced that may be hard to find elsewhere. Here’s an example of a“who’s hiring” thread in May 2017.

By commenting on different articles and reaching out to different members in the Hacker News community, many of whom are senior figures in the startup world, you might also find your way to different mentors — and somebody who can introduce you to the right hiring manager.

AngelList

AngelList is an online repository for different startups. The jobs on offer here tend to be with earlier stage companies working at the edge of technology. One great perk about this is that entrepreneurs may be more willing to accept people from non-traditional backgrounds to work with them — especially if you’re willing to accept and maybe even embrace the risk that comes with working in a startup.

GitHub

GitHub, the living repository of code collaboration, also offers a selection of curated jobs for developers around the world. You can even search by programming language here, ensuring the best match for your skills.

Stack Overflow Jobs

Stack Overflow, the popular Q&A site for programming questions, offers a selection of different programming jobs, many of them posted by hiring managers who are trying to find top talent within the Stack Overflow community.

Glassdoor

Glassdoor is an interesting job board since you’ll be able to see what employees think about the company and you can get some transparency on the salary range the company offers as well. All in all, Glassdoor is a great general place to find technology jobs — but its greatest value probably rests in the additional data on employee satisfaction and approximate salary ranges that can help guide your career decisions.

Mashable

Mashable, the popular content repository based out of New York City, has a job board as well with a lot of different technology job postings.

The Muse

The Muse is a unique jobs resource, with tons of personalized career coaching and resources related to career development. It can be well worth browsing the content on the site itself if you want to learn about salary negotiation, interviews and career progression from a somewhat general perspective. The jobs board section also boasts a selection of technical and developer jobs.

The most popular deep learning libraries

You might have heard of artificial intelligence, deep learning and neural networks, and wanted to get a path into this exciting new technology. This article will help you get a comprehensive overview of the tools and frameworks you can use to accelerate your impact and learning in artificial intelligence. It will help you understand what deep learning library you should use to accelerate your learning. 

This article assumes your familiarity with basic deep learning concepts — if you need to catch up on those, the following Wikipedia article will help you get to scratch.

This is a walkthrough of the most popular deep learning libraries, examples of clever projects and implementations that have used the different libraries to create something awesome.

I’ve ranked the deep learning libraries in question by the number of Github stars their repositories have collected as of June 2017 — a great way to see how much traction these different frameworks have with programmers.

Deep learning library


1- TensorFlow

Overview: TensorFlow is the open-source machine learning library developed by Google (and still used in both research and production level applications at the company). The library allows you to bring machine intelligence capabilities to all sorts of devices, from those equipped with GPUs to mobile devices such as the Raspberry Pi. With over open-source 6,000 repositories using TensorFlow, it has quickly become one of the most popular frameworks out there for those looking to build something with deep learning. TensorFlow is very accessible, with APIs for Python, C++, Haskell, Java, Go and Rust and a 3rd party package built in R.

Introductory Tutorial: Get introduced to TensorFlow with this official tutorial by Google by using TensorFlow with the famous MNIST dataset.

Use Cases: TensorFlow has become of the most popularized deep learning frameworks, and as such, it has seen a wide array of uses from powering cutting-edge machine learning work at different Silicon Valley companies to classifying cucumbers for farmers.

Resources:

  1. This Github repository TensorFlow-World contains a bunch of introductory tutorials with code compiled together to give you a better sense of how to do deep learning on TensorFlow.
  2. TensorFlow-101 contains tutorials on how to get started with TensorFlow in Jupyter Notebook with Python.
  3. This Github repository contains example code that will help you work through different analyses in TensorFlow.  

How to get started: Get all of the documentation and installation instructions here, then start practicing and training deep learning models on different datasets! TensorFlow is one of the most popular and powerful deep learning frameworks out there: take advantage! 


2- Scikit-learn

Overview: Scikit-learn is the versatile machine learning knife in Python, used for simple experimentation and iteration with different templated machine learning models. With modules like the MLPClassifier, you can easily bring deep learning approaches to your datasets and use the rest of the trusty scikit-learn ensemble (such as train_test_split) to validate and evaluate your model. You can also combine the scikit-learn interface with different deep learning libraries if you want to do more powerful analyses.

Introductory Tutorial: This tutorial runs through how to use scikit-learn as a deep learning library and a multilevel perceptron model to classify different types of wine. You can see how with a few lines of code, you can create a very accurate model with many variables.  

Use Cases: scikit-learn is often the first go-to deep learning tool for people working in the Python data science ecosystem: it comes pre-installed with Jupyter Notebook and it comes with powerful functions that are already-optimized versions of essential deep learning functions. You’ll be able to quickly build together machine learning models, evaluate them, and split different use cases into either test or training sets.

Resources:

  1. This cheatsheet by Datacamp will help you with many of the essential functions in scikit-learn.
  2. Springboard has a tutorial that will teach you how to build a simple neural network with scikit-learn and its MLPClassifier module.
  3. This gentle introduction into scikit-learn can help you ease into this machine learning package.

How to get started: Use jupyter notebook, which comes with scikit-learn installed by default. Start training machine learning models, then move into Scikit Flow, an interface that combines the code you’d use in scikit-learn augmented with functionality from Google’s TensorFlow library (we’ll dive into TensorFlow a little bit later in this article).


3- Caffe

Overview: Caffe is a deep learning framework built by Berkeley’s AI Research department (BAIR) and sustained through the use of community contributors. It features speedy application of deep learning approaches, with the ability to classify up to 60 million images a day on a single GPU. It powers a variety of deep learning projects in machine vision, speech and more — with projects ranging from fully fleshed out applications to academic papers.

Introductory Tutorial: This tutorial built by Berkeley AI researchers will help you get up to speed with this powerful deep learning framework.

Use Cases: Caffe is used for a variety of academic research — this web page has a ton of examples ranging from image classification to training the classic LeNet model.

Resources:

  1. This blog post will help you get up to scratch with using Caffe and Python with a relevant classification example from Kaggle on how to distinguish between dogs and cats.
  2. This tutorial will help you with loading Caffe onto iPython Notebook and also with C++ implementations of the library.
  3. This tutorial will get you to understand how you can build a layer of a neural network within Caffe.

How to get started: Use the command line and get started with different use cases of Caffe. You can use this tutorial to get installation instructions across a whole array of different platforms.


4- Keras

Overview: Keras is an open source deep learning library for neural networks written in Python. Authored by François Chollet, the library was meant to be a quick and easy way to experiment with different deep learning models — as a high-level API written entirely in Python, the library is easy to debug and navigate. It supports both convolutional and recurrent neural networks and it is designed to be as intuitive as possible for users to grasp.

Introductory Tutorial: This introductory tutorial will run over how to get started with Keras — all the way from installing the package to training a model with 99% predictive accuracy on the seminal MNIST dataset.

101+ Resources to Learn Data Science

Many people are seeking to learn data science these days. It’s become a trendy topic associated with high salaries and some of the most interesting problems in the world. This demand has created many different resources in the data science space. People have curated their selection of favorite resources to learn data science, but I was seeking out something more comprehensive — so I built this list. Here’s my attempt at getting you my favorite resources in the data science space so you can understand what’s going on in the field — and how you can get your hands dirty and start learning right away.

Full disclosure: I work for Springboard (one of the data science education providers listed below). 

What is data science?

learn data science

First, let’s start with an overview of what seems to have become a popularized buzzword and defining exactly what you want to learn: data science. Data science is the combination of three kinds of skillsets: statistics, programming and business knowledge. It’s the interplay between these crafts where you’ll find a data scientist — somebody who will programmatically examine large data sets for precious business insights — somebody who can combine computer science knowledge with business insight.

You can use data science concepts and training to do data mining and get statistical inferences from large datasets. Using advanced techniques such as natural language processing and unsupervised learning, you can tame the power of computation and get precious data insights others simply cannot access. That will be attractive to all sorts of potential employers in the data science field, from Silicon Valley to Wall Street.

In order to get there though, you have to start with the basic techniques and basic concepts that underlie data science. Learning data science requires having an understanding of the process that goes behind it, and the various components that are required to bring everything together. Let’s get started on getting you know that knowledge.

Great blog posts, podcasts and online courses to help you get started

It seems like machine learning and artificial intelligence are topics at the top of everyone’s mind in tech. Be it autonomous cars, robots, or machine intelligence in general, everyone’s talking about machines getting smarter and being able to do more.

Yet for many developers, machine learning and artificial intelligence are dense terms representing complex problems they just don’t have time to learn.

I’ve spoken with lots of developers and CTOs about Fuzzy.io and our mission to make it easy for developers to start bringing intelligent decision-making to their software without needing huge amounts of data or AI expertise. A lot of them were curious to learn more about the greater landscape of machine learning.

You can describe machine learning as using techniques to help computers learn new ways of uncovering insights from data. This deep dive into the topic will explore many elements outside of this short guide if you’re interested in learning more.

What you need to understand before you learn machine learning is that it’s not a magic buzzword that will help solve every problem with you. Machine learning is a practical way to get more data insights with less work. Nothing more, nothing less. 

To quote a professor in the field, “Machine learning is not magic; it can’t get something from nothing. What it does is get more from less. Programming, like all engineering, is a lot of work: we have to build everything from scratch. Learning is more like farming, which lets nature do most of the work. Farmers combine seeds with nutrients to grow crops. Learners combine knowledge with data to grow programs.”

If that excites you, here are some of the links to articles, podcasts and courses about machine learning that I’ve shared with my friends who were eager to learn more. I hope you enjoy!

If you’re more of a visual learner, you can learn about the fundamentals of using Python for the web with this excellent free Udacity course. Of course, there’s more where that came from, with a variety of courses from everything to data fundamentals in Python to machine learning. I went through the series myself, and though it’s a bit long (and there are a lot of exercises that I didn’t think added that much value), the end result was that I came out of the tutorial with a deeper understanding of how data moves across the web.

You can also catch plenty of Python videos on Coursera, Treehouse and Udemy.

3- Look through lists of Python Learning Resources

This might be a little bit meta, but I love lists of resources. One of the hidden secrets to finding those great resources are going through Github repositories. Github is the Google Docs of code, a great collection of “repositories” where coders can “commit” their code to a shared codebase. It’s also a place where people love compiling great collections of programming resources.

This particular link above is a favorite collection of mine. I hope you enjoy it as much as I do.

4- Anaconda and iPython Notebook

Anaconda and iPython Notebook are what I commonly refer to as the “Excel” of Python. It can be hard to work with the Python interpreter (the command line prompt where you enter Python code if you install it from Python.org) as is. You can’t really refer back to the work that you’ve done before very easily without saving a whole variety of Python files, and it can be pretty hard to share your code with the web at large in HTML form, especially with different charts and graphs and a structured flow you want to convey that goes beyond just one Python script.

iPython Notebooks allow you to write your code in Notebook form.

Anaconda and iPython Notebook make it intuitive and visually appealing to organize different Python software modules, and bring them together so that you can work and show your results as easily as possible with nbviewer, which generates a HTML version of your Notebooks that you can share on Github. A lot of popular modules we talk about like Pandas are pre-installed, saving you some time. When you click on the next link, you’ll see exactly what it looks like using iPython Notebook.

5-Slice and dice data with Pandas

Built on the aforementioned iPython Notebook, Julia Evans has created a “cookbook” for the Pandas module, a collection of Python code that can help you handle relatively large data sets with ease.

Python can only help you process what you can fit in memory on your computer, but that’s more than enough for most of your data needs. Pandas will help you efficiently process that data: you’ll be able to read from very large CSVs and clean them up so you can find great data insights and visualize them (more on that in point #10!)

6-Build something small with Flask

Flask is what is termed as a micro-framework, a set of code that you can lean on to build small web projects. It has a bunch of reuseable components that help you build interactive websites that can both receive and transmit data. Give it a try: in a few lines of codes, you can get something interactive going on the web!

7-Build something big with Django

If you’re tired of the word micro, and want to go with a full web framework, build something with Django! Django is used to this day to build very large websites including Pinterest, and Instagram.

django with code(love)

Take a bite out of the web with Django!

8-Play around with Python APIs and even more!

We had a list of learning resources before on Github, now we can explore a list of the things that make Python awesome! I especially love using Python to play with Application Programming Interfaces or APIs. APIs are a set of rules for servers to communicate data with one another: what this means is that with Python, you can scrape your personal fitness information from your Fitbit or work with Google Sheets automation easily. You can do anything that involves getting data from a server willing to give it to you.

You’ll find a list of really cool APIs above that will allow you to play with all sorts of cool data!

9-Do some machine learning with Python

Have you heard of machine learning? It’s all the rage today and the reason why is because it allows you to do more with less. By having machines learn patterns in your data and by being able to infer conclusions from smaller data sets to larger populations with their insights, machine learning lets you know more about the world around you with less data points.

This Github repository offers a fantastic dive into the fundamentals of machine learning, and gets you to practically embark on your machine learning adventure with sample code sets.

10-Tell data stories with Plotly

Data doesn’t mean anything unless you can storytell with it. You can throw all the numbers in the world at people but it won’t mean they’re any closer to understanding your point. You really have to break down your data into meaningful chunks for it to go anywhere.

Thankfully, Plot.ly can help with that. With a few lines of Python, you’ll be well on your way to doing bar graphs, charts, and figures of all kinds.

Plotly with code(love)

An example of what you can do with Plotly!

11-Do coding challenges in Python

Now that you’re done learning all of the fun stuff in Python, it’s time to put yourself up to the test! Use HackerRank challenges to test your skills: you could even get a job out of it!

HackerRank allows you to complete problems in the coding language of your choice and allows you to demonstrate your skill with clean code that solves problems in a short amount of time.

Python is a wonderful language for programming beginners, and powerful enough to explore multiple areas of data, machine learning, artificial intelligence and other advanced computer science concepts. It’s the perfect mix for anybody who is getting into programming or who wants to develop their skills further. With these resources you’ll be able to learn and work with Python!

Share this list of resources if it can help somebody–and let me know what else could be added to this list in the comments 🙂

Nine free, brilliant resources to learn data mining

I’m a big fan of playing with data.

In my earlier corporate life, I often used Excel to look through thousands of lines of spreadsheet goodness. I assumed what I was doing was “big data”, and I prided myself on my association with a trendy buzzword.

I know better now. A lot better.

If you’ve ventured here, you’re probably looking into data science, the mysterious science that seems to verge on mysticism in the press. The virtues of data are constantly praised as innovative and disruptive. They seem like the domain of an exclusive few practitioners lifting numbers into actionable insight.

Harvard Business Review went as far as to saying that the data scientist was the sexiest job of the 21st century.

It seems that data scientists create many of the most exciting projects at the cutting-edge of technology. The people you may know on LinkedIn appear thanks to data mining. Amazon’s book recommendations rely on computers to mine your book preferences and select the one book that is most likely to appeal to you. Facebook finds what posts you like, and serves you more of the same. Google finds out who you are, and filters search results and ads for you.

If I like computers, the search term Python will return me the programming language. If I like snakes, it will return me a whole bunch of snakes.

This is all down to the magic of data mining. You’re here because you want to look behind the veil and learn how to do all this.

It’s hard, but not as hard as you think. Data science, at its’ core, is all about using computing power to parse through huge data sets.

Learning Artificial Intelligence

Last year, my partner and I designed Gump, a Voice-Commanded Bipedal Robot for our Engineering Graduation Project. Gump won first place in the Engineering Faculty for Best Project and is currently featured in Engineering News Magazine at Concordia.

The moment we saw our robot walk on two legs for the first time and respond to the sound of our voice was miraculous.

That moment is when we knew we wanted to work on artificial intelligence for the rest of our lives.

Learning Artificial Intelligence with code(love)

Learning Artificial Intelligence with code(love)

That moment is when we knew we wanted to work on artificial intelligence for the rest of our lives.

As technology grows, so does the information that is available to us.

We began working on artificial intelligence in the NLP (Natural Language Processing) domain, something that allowed machines to understand and process human language patterns. We worked on speech recognition and now we are doing text analysis using artificial intelligence.

We’ve learned that the possibilities of using artificial intelligence are endless. Learning artificial intelligence is crucial to understanding how the 21st century will unroll—Chris Dixon, a prominent venture capitalist, argues that the next 10,000 startup ideas are clear: take x and add artificial intelligence to it.

With artificial intelligence, you can get unlimited insights from Big Data. Imagine measuring the mood of iPhone Users on Twitter after Apple’s latest product launch, gauging the world’s opinion on a major event like Russia’s invasion of the Ukraine, or predicting a company’s performance based on previous financial data, without any need for a human to relay that information to us.

Imagine a world where machines can automatically process information, and present it to use in a relatable and relevant form. This is what artificial intelligence proposes.

Artificial intelligence can help us all be more informed in less time, allowing us to make quicker decisions by getting the insights and analytics we need from Big Data.

Learning Artificial Intelligence

Learning Artificial Intelligence

Because of all this, I’m excited about artificial intelligence. I want you to be as excited as I am, so I’ve decided to highlight some ways to get started with artificial intelligence using resources available online

1-NLTK with Python

NLTK stands for Natural Language Tool Kit, an open source library with lot’s of functions to help you use NLP and artificial intelligence. to solve a problem or work on a project. You must know Python to get started with NLTK. To begin your path, I recommend the Coursera class offered by Stanford University. You might want to brush up on your Python skills with this great book for Python and NLTK beginners and then level up and learn more about Natural Language Processing by looking at this book.

2- IBM Watson Sandbox

Watson is IBM’s artificial intelligence., famous for defeating two human contestants on Jeopardy by having only the Wikipedia database to answer questions. It is considered the gold standard for artificial intelligence nowadays. IBM released a sandbox version for using Watson’s APIs for 30 days, which allows you to hack away and create a cognitive application.

If you want to use Watson for your next big thing, you won’t be able to unless you’re a Series B Funded startup, but that will change in the future. The access IBM has given to Watson now bodes well for the future. The ecosystem is still evolving, but it is the gold standard of artificial intelligence, and IBM is working to make it more accessible.

3- Udacity Courses

Sign up for the free courses on Udacity for Introduction to Artificial Intelligence, and the three Machine Learning Courses offered there. There are tons of resources and a community there to answer all your questions. We personally believe that Machine Learning should be a mandatory course for every Software Engineer and Computer Science Major.

Check out the forums as well, they’re very insightful and they will help guide you step by step.

4- MATLAB’s Neural Network Toolbox

This one is costly, but if you can get a MATLAB license with Neural Network Toolbox license as an add on, you have a very powerful system to play with. NNT is an Artificial Neural Network that has amazing capabilities for your project like speech recognition, image recognition, and object detection. We loved playing with NNT for our robot, Gump.

With a few lines of code, you can create artificial “neurons” in your program. The neurons can be assigned to do several things. We created eight neurons with MATLAB, each one assigned to a specific voice command. After that, we trained the neurons by recording over 5,000 voice samples from every person we could find on campus. The more voice recordings each neuron had per voice command, the more it grew in knowledge. When we tested it, the response was just perfect! MATLAB is immensely powerful.

Those resources will help you get started with learning artificial intelligence.

Leave comments below if you found this helpful, or know of other resources!

This post was written by Yaz Khoury, the founder of an A.I startup called Summarit that uses artificial intelligence to summarize articles for students.

Ten curated resources for you to learn code and entrepreneurship.

Imagine a world where you could access information as easily as you could breathe.

You can stop imagining: this is the world we live in.

With Google, almost everything can be a finger tap away. With the right keywords, you can access the right information.

The challenge now isn’t a lack of information—it’s how to access that information in a curated fashion.

In that sense, Github, the hub for open source software has become a good way to organize information. By modifying the README files typically used to document how software is used into a list or a resource itself, the open source movement is applying yet another twist to how it can leverage existing resources in new ways to solve old problems.

It is innovation in action. The best part of it is that you can contribute even if you’re non-technical by getting an account, and making pull requests that change the text: you update the text how you will, and then you can push the changes to moderators who will look over your proposed changes, or reject them.

Here’s a guide on how to go about doing that:
