Is Go an Object-Oriented Language? Yes and No. Although Go has types and methods and allows an object-oriented style of programming, there is no type hierarchy. The concept of “interface” in Go provides a different approach that we believe is easy to use and in some ways more general. There are also ways to embed types...

Under the Hood Have you ever found yourself writing code and wondering exactly what is going on under the hood? How does programming really work? In an attempt to peel back at least one of the curtains, Jessica Betts and I created our own Esoteric Programming Language based on Lord of the Rings lore called My_Precious. There are many...
WhiteSource review of programming language security errors reveal which languages have the most security holes. The winner? C. But that’s only the start of the story. From top to bottom, technology is riddled with security errors. At the lowest level, we have hardware errors such as Intel’s Meltdown and Spectre bugs. Just above those, we have...
Spoilers: One coding language ended up on both the most loved and most hated lists, according to a Hired report. Employer demand for certain programming languages may be strong, but that doesn’t mean developers always love coding in those languages, according to Hired’s 2019 State of Software Engineers report, released Thursday. What’s Hot at TechRepublic Inside the Raspberry...
Microsoft TypeScript is popular and it’s here to stay as a prominent language, according to analyst RedMonk. TypeScript, Microsoft’s language for building JavaScript at scale, is now one of the most popular languages with developers and hot on the heels of Apple-backed Swift. TypeScript, released by Microsoft in 2012, is now in 12th spot in the...

How were programming languages built? Here’s a brief history. We, humans, have always been on the lookout for somebody to do our heavy and unwanted lifting. First it was simple machines, then steam powered beasts, and at the end a bunch of semiconductors and a quartz. But how do you get a simple stone to do...
Atto is an insanely simple functional programming language It features a syntax driven entirely by polish notation and no delimiters to speak of (it ignores all non-separating whitespace). What do you get for this simplicity? Well… an insanely simple language with a ~200 line self-hosted interpreter. Despite these design limitations, it’s actually possible to write...
This is the 12th in a series of class notes as I go through the Georgia Tech/Udacity Machine Learning course. The class textbook is Machine Learning by Tom Mitchell. This marks the start of a new miniseries on Unsupervised Learning, the 2nd of 3 sub disciplines within Machine Learning. Our Goal: Optimization Given an input space X, and an...
This is the third post of a series about asynchronous programming. The whole series tries to answer the simple question: “What is asynchrony?”. At first, when I just started digging into the question – I thought that I know what it is. It turned out that I didn’t know a clue about what asynchrony is...
It is common secret that Python programming language has a solid claim to being the fastest-growing major programming language witnessing an extraordinary growth in the last five years, as seen by Stack Overflow traffic. Based on data describing the Stack Overflow question views which go to late 2011, the growth of Python relative to five other major...
Never ask advice of someone with whom you wouldn’t want to trade places — Darren Hardy The idea to collect a list of books that knowledgeable, experienced and well-known programmers recommends to read comes to me from The long Journey to Ruby Mastery conference talk by Bozhidar Batsov. Here I share what I have found so far: the books recommendations...
Have you went through the official React’s Tic Tac Toe tutorial? If you have, you might notice this bolded text in the introduction You might be tempted to skip it because you’re not building games — but give it a chance. I’m guessing even React team knows that it’s not that interesting to build a Tic...
I can honestly say I have enjoyed working with Java for quite some time now. When I first became a developer, I worked with backend technologies like EJB2, DB2, and Oracle. From there, I moved towards natural language processing-based bots including Spring Boot, Redis, RabbitMQ, Open NLP, IBM Watson, and UIMA. For years, my language...
Julia Programming Language is Fastest Growing Than Others, Stat Charts Rapid Rise in 2018-19 By Kimberly Cook | 28-Jan-2019 | 37470 Views Up-and-coming language Julia programming language is gaining momentum with programmers, according to its creators. Julia, created in 2009 by MIT researchers, made its public debut in 2012 and over the past year has quickly climbed the ranks...
Lists are a basic building block for a developer in any language. Python is no different. However at first, list comprehension can sometimes seem confusing. Since it is not an available feature in all languages, it may also be a concept that is completely unfamiliar. Some popular languages that include list comprehension are JavaScript, Perl...
