How to become more agile and productive with better coding habits If you’ve tried your hand at machine learning or data science, you know that code can get messy, quickly. Actual footage of me writing data science code Typically, code to train ML models is written in Jupyter notebooks and it’s full of (i) side effects...
Iterables, functions, and generators in Python To learn about the yield keyword, there are a variety of other terms and concepts that you must be comfortable with first. Before we dive into all of that, let’s keep the end in mind and talk through why yield is beneficial. Using yield will improve the memory efficiency — and subsequently, the speed/performance — when...
A Quick Look at Lists Lists were one of the first things I learned about when I started exploring Python, and it wasn’t long before I realized they are a commonly used feature of the programming language. A list in the Python language is an ordered and mutable data structure that contains a collection of items...
Python 3.8 released a few weeks ago, and rather than jumping the gun on talking about the new features, I decided I wanted to get familiar with them and utilize them, and I would like to point out that I am absolutely going to be using a few of the key features implemented in Python...
Let’s be honest. A lot of JavaScript code sucks. Change that! JavaScript is a force to be reckoned with. It is the single most widely-used programming language in the world. Its simplicity and the abundance of learning resources make it approachable for beginners. Large talent pools make JavaScript appealing to companies of all sizes. A...
While programming or coding, a programmer can sometimes take hours of time to solve an error. Autocomplete tools serve as a great helping hand as it helps them to complete the code faster while reducing the errors. In this article, we list down 4 autocomplete coding tools for Python programmers. 1| Kite Kite is a powerful editor integration...
Swirl into a game-existencewhere you and your friend are miners. Yep, the yellow hat and shovel in hand. The task — Dig up a hole within a certain time to be able to extract some sparkly diamonds! So your friend suggests that you and they take turns digging… Let’s say it takes you 100 minutes to finish this task when done...
Understanding is vital when it comes to coding Python in many ways has made our life easier when it comes to programming. With its many libraries and functionalities, sometimes we forget to focus on some of the useful things it offers. One of such functionalities are generators and generator expressions. I stalled learning about them for...
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...
As a developer, you have the power to change the world! You can write programs that enable new technologies. For instance, develop software to find an earlier diagnosis of diseases. But, that’s not the only way, you might do it indirectly by creating projects that make people more productive and help them free up time...
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...
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...
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...
Anytime we go into a project, existent or newly created, we always think about how what we’ll build can be more manageable, scalable and and easy to test. This is where using Dependency Injection can come in handy for us. But first, what do we mean by Dependency Injection? It is a software design pattern that...
this is of course the source of much confusion in JavaScript. The reason being that this depends on how the function was invoked, not where the function was defined. JavaScript without this looks like a better functional programming language. this losing context Methods are functions that are stored in objects. In order for a function to know on which object to...
Here’s a neat Python trick you might just find useful one day. Let’s look at how you can dynamically define classes, and create instances of them as required. This trick makes use of Python’s object oriented programming (OOP) capabilities, so we’ll review those first. Classes and objects Python is an object-oriented language, meaning it lets you...
Recently, I needed a piece of software where you can input some numbers, validate and process them, and print some result. Since I needed to do scientific computing with it I decided to use Python with NumPy and SciPyand because I needed validation I decided that HMTL input validations would be the easiest to use. Then I had...
There are concepts which are very similar, yet different and confuses many people. Referential transparency vs immutability Referential transparency is a concept in a programming language which guarantees that once the value is assigned to the variable it will not changethere is no way to assign a different value to it. For example, in ES6 you...
Originally posted at carloscuesta’s blog It’s been a while since I’ve started working with React and React-Native in production. One of the greatest things about React is the flexibility the library gives to you. Meaning that you are free to decide how do you want to implement almost every detail of your project for example the architecture and structure. However this freedom on the long term, could...
