Preparation
Although I’m interested in machine learning positions, the positions at the five companies are slightly different in the title and the interviewing process. Three are machine learning engineer (LinkedIn, Google, Facebook), one is data engineer (Salesforce), and one is software engineer in general (Airbnb). Therefore I needed to prepare for three different areas: coding, machine learning, and system design.

I mainly used Leetcode and Geeksforgeeks for practicing, but Hackerrank and Lintcode are also good places. I spent several weeks going over common data structures and algorithms, then focused on areas I wasn’t too familiar with, and finally did some frequently seen problems. Due to my time constraints I usually did two problems per day.

This updated 2018 list features 10 websites that offer the best coding challenges and resources to help new and intermediate developers improve their skills, prepare for interviews, and progress in their careers. The ordering of the list is based on level of difficulty (beginner to advanced).

After immersing myself in it for a year, I find Swift to be deeply web in its soul. From its expressive, functional syntax and its interpretive playgrounds to its runtime performance and recent foray into open source, Swift is the web developer’s compiled language (with the mature and convenient safeguards characteristic of the compiled environment).

Everything you need to get you started is here. It’s free. And the community is amazing.

The book, and its successors like Machine Code for Beginners and Practical Things to Do With a Microcomputer were major hits–but they were largely forgotten until recently when Usborne published them online as free PDFs, as Cory Doctorow first pointed out this week.

To help further this exploration, Reas and his colleague Ben Fry (a principal of Fathom, a design and software consultancy in Boston) in 2001 developed their own software, called Processing, that bridges the divide between programming and art, making both processes more intuitive.

When it comes to relational databases, I can’t help thinking that something is missing. They’re used everywhere. There are many different databases: from the small and useful SQLite to the powerful Teradata. But, there are only a few articles that explain how a database works.

If you could go back in time and tell yourself to read a specific book at the beginning of your career as a developer, which book would it be?

Here are 8 fantastic projects to train your coding muscles! The goal is to build each app with whatever technology stack you prefer. Keep it conflict free, use whatever you want!

Create and share beautiful images of your source code.
Start typing or drop a file into the text area to get started.

One my prefered playgrounds is SVG. It is Scalable Vector Graphics, which in practice means that you can draw something in the browser using some tags, some stying and some code. How cool is that? Compared with a piece of paper and a pen you can go crazy and the result is generated instantly as you change the elements of your playground in your pen on CodePen.

This site is a companion to the influential computer-science text Structure and Interpretation of Computer Programs, by Abelson, Sussman, and Sussman. Its purpose is to demonstrate the Web's potential to be a channel for innovative support for textbook users.

In this article, we’ll look at the development of desktop applications using NW.js and Electron, the ups and downs of building one and living with one, using one code base for the desktop and the web, and more.

Zines about computer science! Each zine focuses on one concept & is filled with comics, diagrams, stories, examples, and exercises.

Original dissertation

For the last few years, whenever somebody wants to start building an HTTP API, they pretty much exclusively use REST as the go-to architectural style, over alternative approaches such as XML-RPC, SOAP and JSON-RPC. REST is made out by many to be ultimately superior to the other “RPC-based” approaches, which is a bit misleading because they are just different.

So, you want to become a coder. That’s great! No, really. There is much about coding that makes it worth pursuing. Getting started, however, can be a daunting task. Even with all the enthusiasm and energy you have for learning, you might find certain obstacles are presenting themselves to you, making it difficult to gain momentum.

Everybody loves the vintage game Pong, right? We sure do. What's more fun? Building it yourself!

That's why we decided to create one with SVG.js - to highlight some aspects of our library. It might seem like a complex idea for a small tutorial, but as you'll see, it's simpler than it sounds. Let's dive into it!
