How to Make Up Your Mind Between Node.js and Python

See the original posting on DZone Python

There is no such thing as the best programming language. There are languages that are used for more specific things than others. If you need a mobile application, web app, or a more specialized system, there may be a specific language. But let’s assume for the moment that what you need is a relatively simple website, where you can show your client’s products and maybe sell them online efficiently.

In this article, we have chosen to evaluate Node.js and Python to help you decide on the ideal programming solution.

JavaScript Enterprise Container: From Java to Node.js

See the original posting on DZone Python

This article introduces the “JavaScript Enterprise Container” (JEC) project for both Java and JavaScript developers. It will show a flexible development environment for building enterprise applications and microservices over Node.js.

About JEC

JEC is an easy-to-use open source project that executes JavaScript code server-side to deploy web applications, such as microservices, RESTful APIs, CDN platforms, etc.

React Component Lifecycle

See the original posting on DZone Python

All React components go through a lifecycle which enables you to perform a specific task at any specific time. In order to achieve that, you can override the lifecycle methods. Methods prefixed with will are called right before something occurs (events), and methods prefixed with did are called right after something occurs.

Let us understand all the functions in all the phases of the lifecycle:

A Direct Comparison of WCF and ASP.NET Core Functionalities

See the original posting on DZone Python

A lot of money and energy was invested by Microsoft to develop ASP.NET Core. This is an open source platform to which features and services can be added by the wider developer community. Some assume that ASP.NET Core has multiple advantages over other open source platforms like WCF. But this is not always the case; let’s have a close look at the matter.

In this article, our main focus is to compare the performance of WCF (Windows Communication Foundation) and ASP.NET Core, so that you can decide for yourself which technology is best for you. To judge the performance of both the platforms, let us take a simple example – “stand up a local web server.” Let’s check how much time it takes for the web server to generate a request, how much time it takes to route the request, serialize the request, to create a response, and send the response back and deserialize it.

Choosing the Right JavaScript Framework

See the original posting on DZone Python

The emergence of unique frameworks, with each of them having distinct advantages, has caused a rift in our wonderful JavaScript community. Developers advocating for their favorites as the golden era of technological wonder has started, the sun has set for the outdated libraries. Amidst all this chaos comes a very irritating question as to which framework is the best; the answer to which is all of them. While there are countless alternatives to the libraries, the important thing is to understand your requirements.

Framework or Libraries

While frameworks are used by a developer to customize everything within the software/app/website by modifying the code in accordance with the framework rules, libraries, on the other hand, provide you with the functionality that can be directly used by you while coding.

CSS: :before and :after

See the original posting on DZone Python

The CSS :before and :after properties are what are also known as pseudo elements. They are used to add something before or after the content of an element. There are a lot of great uses for these pseudo elements, and we are here to explore some of them.

The Syntax

If we have an element like this one:

Angular 6 Release vs. Angular 5: New Features and Improvements

See the original posting on DZone Python

Calling all Angulars!  Angular 6 is out, a major release from Team Angular.

Great new features, annoying bug fixes and much more, the latest Angular Version holds new exciting things for us. Let’s do an in-n-out of Angular 6 to see if it lives up to the hype, and while we do that, I would also like to compare Angular 5 with 6 to see what are the differences and upgrades in this latest version release.

How to Close Your Code

See the original posting on DZone Python

We all know about SOLID principles. Every developer knows what are SOLID principles because every developer has to go through an interview process to get a job. Some can explain really well while they’re interviewing

Recently, I was interviewed by a very reputed financial company. They have 4 rounds of interview and of those, 3 rounds asked a question about SOLID principles. They all asked very good interesting questions and it seems they were looking for some specific expertise. I started working there and their code base is awesome. They are not working anywhere near what they asked in an interview. I also found some controller code files has 2-3k lines of code, which is a presentation layer. Though they have very nice onion architecture for the project, I hope whoever worked there all went through that interview process and knows at least a little about SOLID principles. These principles are not just to perform in the interview; we need to apply it in real code. Maybe they have their own reasons for not following them.

How Programming is Evolving

See the original posting on DZone Python

Technology has transformed the world into a synchronized global village. The ever-changing world of technology has increased the pace in which software development is evolving. In fact, software and app development is the most advancing and dynamic fields of information technology. Most people think of things such as HTML when they hear about app development. Only a few have an idea of what web development vs. software development is and its impact on the survival of software developers in today’s digital era. In fact, the speed in which technology is accelerating has made some programming technologies obsolete. The software development industry will be affected by the continued adoption of new technologies. The latest tech programming trends will bring broader capabilities and increase the speed of software deployment. Improved efficiency, a friendly user interface, and customization are some of the factors that are driving the change in these programming technologies. The newest programming trends come with multiple technologies that give app developers easy and quick software development solutions.

Increased Adoption of PHP Technology

PHP is a popular tool used as a programing language in the web development world. Over time, it has gained popularity and become one of the widely used tools for web development. You can find it almost everywhere in the world as long as you have an internet connection. Mobile app developers are using this programming language to design websites. It allows web developers to work uniquely. It also supports diverse web development platforms. It’s an incredibly scalable and flexible programming tool that enable mobile app development companies to design websites across the globe.

Build a Video Chat Service with JavaScript, WebRTC, and Okta

See the original posting on DZone Python

As recently as seven short years ago, building video applications on the web was a massive pain. Remember the days of using Flash and proprietary codecs (which often required licensing)? Yuck. In the last few years, video chat technology has dramatically improved and Flash is no longer required.

Today, the video chat landscape is much simpler thanks to WebRTC: an open source project built and maintained by Google, Mozilla, Opera, and others. WebRTC allows you to easily build real-time communication software in your browser and is being standardized at the W3C and IETF levels. Using WebRTC, you can build real-time video chat applications in the browser that actually work well! It’s pretty amazing.

Processing Large Files Using PHP

See the original posting on DZone Python

If you want to process large files using PHP, you may use some of the ordinary PHP functions like file_get_contents() or file() which have a limitation when working with very large files.

Memory Limitation

These functions rely on the memory_limit setting in the php.ini file; you may increase the value but these functions still are not suitable for very large files because these functions will put the entire file contents into memory at one point.

Package Manager Rumble

See the original posting on DZone Python

Along with the discussion of how to use JavaScript comes the discussion of package managers. Modules help us utilize tooling we and other developers make because WHY would you spend time re-writing something that already exists and works well?? If that question has not popped into your head or been repeated in a team meeting at least once in 2017, you might be doing it wrong. Just sayin’.

Thankfully, we have teams creating better and better experiences for us to install and organize these modules. npm, Yarn and Bower are still the leaders of the pack…age management tools, but I also wanted to throw in jspm. With close to two million installs this year, jspm is still going strong. Now, this isn’t going to be a package manager brawl, despite the title of this post. I’ll give you the info and you can decide what it means to you. I’m not going to lie though: I use npm and like their team and what they do a ton. So, if I come across as biased, it’s probably because I am.

Inferred Tuple Names in C# 7.1

See the original posting on DZone Python

Although C# 7.1 doesn’t have many new features, there are still some convenience hacks I like. One of these is inferred tuple names, meaning that we can name tuple members using variable names. It’s not a big change in the language, but it still makes code a little bit cleaner where tuples are used.

New Features in C# 7.1

  1. Switching C# version in Visual Studio
  2. Deep dive to async Main
  3. Inferred tuple names in C# 7.1

In C# 7.0 we had to specify the names of value tuple members like this:

A Word About Node.js Event Loop

See the original posting on DZone Python

Up until recently, I was pretty sure how Node’s Event Loop worked; in fact, I was sure I knew how asynchronous calls were handled.

Recently, thanks to a very interesting talk about this subject by Daniel Khan in last year’s NodeConf, my eyes were opened to the truth. He has a very good explanation in that video, but I decided to go deep into Node’s official documentation about it, and out of that came my own explanation of how this beast known as Event Loop works.

PyCon 2018: Conference Day 1 (May 11)

See the original posting on DZone Python

PyCon 2018 in Cleveland, Ohio, kicked off their first conference day with an introduction from one of Cleveland’s natives, Ernest W. Durbin III. Then, we moved onto the keynote of the morning, which was given by Dan Callahan from Mozilla. He talked about tooling and how Python currently doesn’t have a big presence on the web. It was actually quite interesting and also a bit disappointing as there wasn’t really a true solution given. However, his talk was quite good and insightful.

My first conference talk was Augmenting Human Decision Making with Data Science by Kelsey Pedersen. Kelsey is a good speaker, but the topic didn’t really pull me in. There was no code examples whatsoever and was just kind of a presentation on how the company that Kelsey works for uses data science. You can watch it here, if you like:

Prerequisites

Please refer to my previous article Cascading DropDownList in Blazor Using EF Core to create the application that we will be deploying in this tutorial.

jwt-cli: A Shell Library to Decode JWTs [Snippet]

See the original posting on DZone Python

When I started needing to decode JSON Web Tokens quite often, I felt the urge to write a program that allowed me to do it quickly. There are excellent options, such as jwt.io, but as soon as you need to do this operation often enough, it becomes clumsy. And if you need to process multiple tokens, or further process the output, something else becomes a necessity.

That’s why I wrote a little shell script that allows you to do just that. jwt-decode will accept a list of tokens as arguments and will decode them on a standard output. The syntax is the following:

No-Code Software Development

See the original posting on DZone Python

Every single software bug in the history of computing was created by a software developer, writing a piece of code, that for some reasons didn’t work the way it was supposed to. So I figured "Let’s eliminate the root cause of the problem: writing code."

Some years ago, an acquaintance of mine told me he had just finished a project. His customer wanted to have a web app, wrapping a single table from his database, such that he could perform all CRUD operations on his database — and do some basic sorting and filtering in the process. My acquaintance bragged about how he had only spent 12 hours creating this system, yet still invoiced his customer a fixed price of $20,000. The customer had happily paid, and even mentioned something about how cheap this price was, and how grateful he was. Ignoring the ethical aspect of this story, having a developer invoicing $1667 per hour — this problem is actually quite interesting. I can easily imagine thousands of different use cases, which arguably are an exact match of this specification, only with slightly different columns, and slightly different features. And in fact, I bet most of you have heard similar stories, too, and seen dozens of similar use cases yourselves.

Major Failures: Three in a Row

See the original posting on DZone Python

Recently, I encountered some really bad experiences as a consumer placing an order for a pizza, ordering some items for pick-up from a very popular hardware store, and placing an online order for a gift to be delivered in Florida. In each case, I experienced some level of failure – which are all related to the technical side of the experience. So, I thought I would give some background and provide my findings.
