A balanced binary tree or a height-balanced tree is a tree in which the height of the left and right subtree at any node does not differ by more than one. Not just the root node, at any node. Mathematically we define using a balanced factor.

A common problem in programming language design is the question of what the type of integral literals should be, and if they are untyped, what the rules for implicitly converting them to regular integer types should be. This is part of the more general problem of how to handle having multiple integer types with overflow and the conversions between them. There are many approaches to this problem, but they all have significant downsides.

5 Minutes Project We are going to build a Telegram bot with python and deploy it to Heroku. The bot I am going to build will be able to send random pictures or videos of dogs using dog.ceo API…

More recent additions to the JavaScript language are async functions and the await keyword, added in ECMAScript 2017. These features basically act as syntactic sugar on top of promises, making asynchronous code easier to write and to read afterwards. They make async code look more like old-school synchronous code, so they're well worth learning. This article gives you what you need to know.

The async / await operators make it easier to implement many async Promises. They also allow engineers to write clearer, more succinct, testable code. To understand this subject, you should have a solid understanding of how Promises work. Basic Syntaxfunction slowlyResolvedPromiseFunc(string) { return new Promise(resolve => { setTimeout(() => { resolve(string)

My housemate the other day asked me something to the effect of “How can Software Engineers call themselves engineers when there’s no rules, governing bodies, or anything to stipulate what true Software Engineering is?”

A portion of the report ranks programming languages by their correlating developer salary. If you're looking to get paid well, it might be worth your time to learn Clojure and maybe not Dart.

Hey Everyone! I'm Shantnu, and I'm a 1x Programmer. I've been programming in Python for 10+ years, and yet I still forget how to use basic things like dictionaries and have to Google for itEvery time I open a file in Python, I have to Google what the parameters to

How to represent data schema with JSON schema. Benefits of separating data schema from data representation in Data-Oriented Programming.

Enhancement of the Open Policy Agent Rego type checker did not support some keywords in the JSON Schema 2019-09 release. Now it does.

A How-To Guide on building a WebSocket version 13 client and server from scratch, explaining related RFCs and potential quirks and problems with other implementations.

I learned Java and C at school, I learned Python by myself and it was a relief. After 8 years working and doing side projects in Python and JavaScript (mostly web dev, Django/Flask/AngularJS/Vuejs), I am not satisfied anymore by the overall experience so I’m making Common Lisp my language of choice.I am not here to compare languages themselves, but their inherent workflow and their ecosystem. This is the article I wish I had read earlier, when I was interested in Lisp but was a bit puzzled, because the Lisp way always seemed different, and I couldn’t find many voices to explain it.

Go is regularly criticized for odd decisions and idiosyncrasies, while Rust is celebrated as an almost perfectly designed alternative that solves Go's problems. But in fact, Go and Rust are far from interchangeable.

This tutorial describes how to use the InfluxDB Go client library, create a connection to the database and store and query data from it.

Picking the right performance testing tool can be a challenge. We compare and contrast Locust and Speedscale in this blog.

Low-code app development is here, and thanks to the rise of work from home over the past couple of years, it is here to stay.

How to write self-documenting code. Best practices, tips, and tricks to write code that doesn't require documentation.

LispWorks is a Common Lisp implementation that comes with its own Integrated Development Environment (IDE) and its share of unique features, such as the CAPI GUI toolkit. It is proprietary and provides a free limited version.Here, we will mainly explore its IDE, asking ourselves what it can offer to a seasoned lisper used to Emacs and Slime. The short answer is: more graphical tools, such as an easy to use graphical stepper, a tracer, a code coverage browser or again a class browser.

There's a well-known quote by author Michael Pollan: "Eat food. Not too much. Mostly plants." I like it because it doesn't attempt to be dogmatic: it encapsulates some basic guiding principles that get you 90% of the way there 90% of the time. Wikipedia describes the book the quote is from (emphasis mine):

For many years, the GNU Arm Embedded Toolchain has provided an open-source toolchain targeting embedded systems. The LLVM Embedded Toolchain for Arm is a new open-source project with the goal of pr…

JSON has its place. But I think we're overusing it in places where a good notation would serve us better.

YAML (YAML Ain't Markup Language) is a human-readable data serialization language. Its syntax is simple and human-readable. It does not contain quotation marks, opening and closing tags, or braces. It does not contain anything which might make it harder for humans to parse nesting rules. You can scan your YAML document and immediately know what's going on. [OS_EMBEDDED_MENU_RIGHT:] YAML features YAML has some super features which make it superior to other serialization formats:
