NodeJS a Niche Framework – But Still a Good One

Written by Liam Grant. Posted in Computers

Any competent web app developer will have numerous frameworks in his/her toolbox. Among them is NodeJS, a framework written using a combination of JavaScript, C, and C++. Despite its popularity, it is not an all-in-one framework that can be used for virtually any project. You might even call NodeJS a niche framework that supports a very specific function. And it supports that function very well. The primary advantage of NodeJS over other development platforms is its ability to accommodate large numbers of simultaneous connections without any performance drop. If that is what you are looking for in your web app, Node.JS development is something you should be involved in. If you’re looking to build an app that’s going to involve even a small number of operations that are CPU intensive, look elsewhere – Node.JS is not your best friend. [Not a valid template]

Multiple Connections Means More Speed

Web applications have to be designed to accommodate a relatively large number of simultaneous connections if they are to be usable for the general population. Most of the other popular connection techniques utilize frameworks that open a brand-new thread every time a new connection is established. But there is a problem with that: adding new threads with each connection quickly eats up RAM. What do you do when the number of connections exceeds the available memory? You have to do a dump. But that means a lot of dumps for a heavily-used app. NodeJS relies on a single thread that can handle thousands of connections simultaneously using non-blocking I/O calls. The key here is non-blocking. Applications using blocking operations render the framework nearly useless by limiting its ability to accept multiple connections on a single thread. Having said that, let us look at some sample numbers. Let’s assume a web application running on a system with 16 GB of RAM; let us also assume that a single thread is assigned a 2 MB memory capacity. The system could allow for as many as 8,000 simultaneous connections with NodeJS. As long as there are no heavy computations or access blocks in play, it’s easy to see how this single thread with thousands of simultaneous connections is superior to other options.

Two-Way Communication Capabilities

There is another area where Node.JS development excels above and beyond its competitors: the arena of two-way communication. NodeJS uses push technology to communicate over the web, effectively opening up bi-directional communication between client and server. This wasn’t technically possible with legacy solutions. Yes, older technologies did make limited use of two-way communications, but all communications had to be initiated by the client. Now this is no longer an issue. Both client and server can initiate communication from their side, giving us a true bi-directional paradigm. The little bit of sandbox communication we used to enjoy through applets and Flash pales in comparison to what NodeJS can do.

Built-In Package Management Seals the Deal

The Node Package Manager (NPM) that comes with NodeJS seals the deal. While this may not seem all that important, the tool makes package management within the environment incredibly easy. NPM can be used just as easily as any Linux package manager for easy access to modules shared by others. And because the NodeJS ecosystem is completely open, anyone can publish and share new modules or borrow the work of others. NodeJS development will never allow you to build complex applications with heavy CPU requirements, but it is the perfect framework for simple applications that require speed and as many simultaneous connections as possible. Yes, NodeJS is a niche framework of sorts. But it is a good one nonetheless.

4 easy steps in creating a salon scheduling app

Written by Liam Grant. Posted in Computers

Today’s rapid changes in technology have a great impact on all industries, which means that as a business owner, if you do not keep up to the latest trends, you might lose your customers. When it comes to beauty salons, one important aspect that is definitely worth investing money in is having a well-established and properly designed salon app that eases the process for customers to book appointments. However, as easy as this may sound, there are some important considerations to keep in mind when designing salon booking software. [Not a valid template]

Step 1 – create the basic layout

When building a mobile app for a beauty salon from scratches, it is necessary to invest a great deal of time and effort and to have vast knowledge in programming and coding in order to obtain the best results and exceed the client’s expectations. The first step is building the app’s basic layout. It is true that today there are numerous platforms that provide mobile app templates that are supposed to make the developer’s job easier, but if you really want to create a unique app, you need to think beyond the limits and create the layout yourself.

Step 2 – personalize the design

Since the app is designed for a beauty salon, it is important to ensure it reflects the salon’s keen sense of aesthetics and beauty. The interface of the app should be easy to use and navigate, with colour scheming that emphasizes the salon’s high quality products and services. The overall visual uniformity should invite customers to access and eventually use the app without wasting too much time wandering and looking where the “book now” button is placed.

Step 3 – review the final version of the app

After taking care of every design aspect related to the online salon scheduling app, make sure you take an overall look at it in order to see whether everything is in the right place. It is recommended to get a second opinion of another developer just to ensure you have not missed anything. Present the final version of the app to your client and ask for their opinion as well, taking into account any other ideas or suggestions they may have.

Step 4 – check the app for bugs and release it

Last but not least, it is highly important to check the app for bugs or other harmful things that might affect the app’s usability and well functioning before actually publishing it on the internet. It is a lot easier to make slight adjustments before making it available online rather than afterwards.

Best options for buying Bitcoins

Before getting an account, there are two important aspects to remember: firstly, the wallet software will occupy some disk space and secondly, you have to collaborate with a reliable Bitcoin seller in order to actually get some currency. If you opt for the online wallet, then the process becomes easier right away. For this reason, most experts advise you to choose the second option.

Creating an online wallet

If you decide to create an online wallet, then you need to sign up on a platform offering dedicated services. For beginners, it is recommended to pick one that provides easy access and a user friendly interface. You will have to list a bank account (namely, yours), so that your virtual card can be linked to your account. Be patient, because it may take some time (up to a week) for the linking to be done. After the procedure is completed, you can select how much virtual currency you need, and your provider will withdraw the equivalent value from your bank account. Now you can start trading!
