How those APIs are built and structured can make or break a company in today’s ultra-competitive world. Poorly-designed APIs can be difficult to use, can fail when they are needed most, and are valuable targets for hackers looking for sensitive data.

The software development life-cycle has a lot of moving parts. A huge problem many large companies have is maintaining a consistent deployment process. Written steps sometimes get skipped; manual deploys are error prone, and home-grown deploy scripts are usually only understood by the person that wrote them. Companies like Netflix, Etsy, and Amazon need to make sure that deployment cycles are smooth and errors are caught as early in the process as possible.

Explicit Interface Implementation is a complex and rarely used technique that allows a single class to inherit from multiple interfaces that have the same method signature. Explicitly implementing each interface, prepending the interface name to the method, allows the same method signature to exist in the same class. I shall not demonstrate that here, but there are plenty of examples of this online. There is another benefit to explicitly implementing an interface, and that is to hide members from being accessed via the class reference. I’ll create an example of this technique using a factory design pattern and Fruit class and a console application that you can step through via F11. If you create a new C# console application in Visual Studio, then copy and paste all of the below code, you can step through (F11) the code to see how it works.

Every programming problem involves some kind of algorithm. An algorithm, in this sense, is a process or set of steps to accomplish a certain tasks; or simply a step-by-step way to solve a problem. There are about 700 programming languages. (Seriously: Here's a list.) So, what to learn and why to learn it - that's what most people are stuck on. From my perspective, you can (and should) choose learn any language. Learning the basics of one on-demand programming language will do you no harm. But: you must select ONE language that becomes your magic spell, and you should always be ready to create something out of it. Learning varieties of languages and not being able to do anything really well is like a curse.

From C++11, std::tuple is an incredible expansion to Modern C++, that offers a fixed-size col­lec­tion of het­ero­ge­neous values. Un­for­tu­nately, tu­ples can be somewhat dubious to manage in a conventional fash­ion. But, subsequently released C++ stan­dard in­tro­duced a few fea­tures & helpers that greatly re­duce the nec­es­sary boil­er­plate. So, in this article, I will explain the variadic template in C++ with the help of unsophisticated tuple 
implementation. And also walks you through a tricky part of tuple i.e. 
loop through tuple element. In spite of the fact that I have shrouded the variadic template in my prior article i.e. C++ Template: A Quick UpToDate Look. So, my focus here would be a blend of variadic template & tuple  implementation with more up to date C++ gauges.

It features an easy-to-learn syntax that allows the programmers to express concepts with less coding. Apart from this, this general-purpose programming language has a dynamic type system, memory management, a wide standard library, and many other features.

Since the big bang in the data technology landscape happened a decade and a half ago, giving rise to technologies like Hadoop, which cater to the four ‘V’s. — volume, variety, velocity, and veracity there has been an uptick in the use of databases with specialized capabilities to cater to different types of data and usage patterns. You can now see companies using graph databases, time-series databases, document databases, and others for different customer and internal workloads.

I find the Monty Hall Problem one of the most fascinating brain teasers, because it seems deceivingly simple. When Marilyn Von Savant, the woman with the highest IQ, answered this brainteaser correctly in 1991, she was inundated with over 10,000 letters from academics and Ph.Ds criticizing her “error”, only to be proven later that she was correct.

Ruby on Rails is a tremendous framework when you want development speed for your project or startup. It’s useful right out of the box and comes with a plethora of behind-the-scenes magic to make your life easier. However, it’s not considered the fastest framework out there in terms of performance.

Acquiring a new skill is good but knowing exactly which path to take in advance is best. For every decision taking to learn something new, there is always this “where” or “what” question. Where will I start, what should I do, where will I get material, what so ever be the case there is always a “where” or “what” question. Knowing exactly which path to take as a newbie in technology is almost impossible unless you follow a strict guide from a mentor or any other source. This article is more like a guide through the walk of a self-taught web developer.

In the beginning, you will most likely try to use a brute force method to solve search problems; this is because it is the easiest and most rudimentary way to find a target. However brute force has a time cost; The Big O notation of brute force is usually and unacceptably equal to or greater than bigO(n²).

![](https://cdn.hackernoon.com/drafts/qb5732ov.png)
Web security is a topic that is often overlooked by frontend developers. When we assess the quality of the website, we often look at metrics like performance, SEO-friendliness, and accessibility, while the website’s capacity to withstand malicious attacks often falls under the radar. And even though the sensitive user data is stored server-side and significant measures must be taken by backend developers to protect the servers, in the end, the responsibility for securing that data is shared between both backend and frontend. While sensitive data may be safely locked in a backend warehouse, the frontend holds the keys to its front door, and stealing them is often the easiest way to gain access.

Learning MongoDB has been one of the things in my checklist for the past 6 months but hasn’t gotten around actually learning it until now. In order to understand writing queries and all I figured it’ll be better to make something instead of just reading and watching some tutorials. So, I’ve decided to make a user registration API i.e, a simple registration form kinda thing with only sign up and sign in functions as of now. As learning Mongo was the main intention, I’ve decided just to make the core app which is the backend functionality and no front end as it’s not necessary and I hate to do it.

WebGL (Web Graphics Library) is a JavaScript API for rendering high-performance interactive 3D and 2D graphics within any compatible web browser without the use of plug-ins. WebGL does so by introducing an API that closely conforms to OpenGL ES 2.0 that can be used in HTML5 <canvas> elements. This conformance makes it possible for the API to take advantage of hardware graphics acceleration provided by the user's device.

Nonetheless Algorithms and Data-Structures are a core part of software because at the end of the day you are just working with data. Data needs to be organized for it to be meaningful just like the letters on this page. Atwh and whAt have the same letters but the latter has meaning because of the organization.

Does programming sound like a stressful job for you? People believe it shouldn’t be since it seems all coders do is sit in front of the screen, typing. There are no life-or-death situations, no enormous responsibility compared to medicine, banking, or accounting. Technically speaking, software development should be one of the calmer jobs out there.

I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.

State management is challenging. We can make it less challenging by making sure we don’t store any redundant information in our state. What do I mean? Let’s say in our program we need to figure out whether people will be allowed in our bar. We can determine this by examining a couple attributes of the person: we can look at his or her age (anyone who is 21 or older may enter the bar) or we can look at whether he or she is an employee of the bar (all bar employees are allowed to enter, regardless of age). Now, we could store all this information in our state object:
