As a software developer, I constantly ask myself: what distinguishes an outstanding developer from a mediocre one? From my observation, it has very little to do with formal education, age, gender, and even industry experience. It has a lot to do with mindset.

• Learn how to learn
• Don’t reinvent the wheel
• Small iterations
• Test, test, test
• Apply learned patterns
• Don’t fall in love with your work

In this article, I’ll share some frequently asked programming interview questions from different interviews for programmers at different levels of experience, from people who have just graduated from college to programmers with one to two years of experience.

If you want to run or update a task when certain files are updated, the make utility can come in handy. The make utility requires a file, Makefile (or makefile), which defines set of tasks to be executed. You may have used make to compile a program from source code. Most open source projects use make to compile a final executable binary, which can then be installed using make install.

When we think about the console, the first thing that comes to mind and the console.log, right? But there are many more methods than those we imagine. Now we will see how to make the most of using the console, and I’ll give you some tips to make them these methods more readable

The following will be a short explanation, along with some solutions, of a popular JavaScript question that tends to get asked in developer interviews.

This question deals with the topics: closures, setTimeout, and scoping.

Preparing for Coding Interviews

There are concepts that are fundamental in programming world. Most of the technical interviews are meant to discover your problem solving skills and knowing those concepts, so besides mastering a programming language, you should be familiar with the concepts that are somewhat required in programmer’s arsenal. Here’s an excerpt from my recent lesson post in SoloLearn (below are the links to Android and iOS apps).

A bunch of Google employees participating in the company’s Area 120 internal incubator have launched Grasshopper, a free mobile app for Android and iOS that teaches you the basics of programming. It’s beautifully designed and is suitable for just about anyone who can be trusted to use a phone on their own.

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.
