Is UX Design a Good Career?

According to an Adobe survey of 500 managers and department heads, 87% of managers said; “hiring more UX Designers was the organization’s top ‎priority”. While 73% said they planned to hire more UX Designers over the ‎next five years. Almost two-thirds (63%) said they had hired five or more UX ‎Designers in 2020. User experience design is an immense, diverse, and enthralling field. It shapes the products and services we use on a daily. And can make or break a company’s or brand’s success. The user experience is the sensation a person has when dealing with a system.

This includes any type of human/device interaction, such as a website, mobile application, desktop software, and so on. UX is essential because it attempts to meet the needs of the user. It seeks to provide amazing outcomes that keep users loyal to a product or brand. Furthermore, defining customer journeys on your product is the most vital step for major success that is only possible through a meaningful user experience.

What is UX Design?

A UX designer is a professional that aims to create a positive relationship between technology and human beings. Any interaction a user has with a product or service is referred to as a user experience (UX). It takes into account all those elements that construct a unique experience as well as how it makes the user perceptions about the product. Further, it involves simplicity as to how it is for the user to complete their tasks successfully. This can range from how a physical product feels in your hand to how simple the checkout process is when purchasing something online. The goal of UX design is to create simple, efficient, relevant, and all-around enjoyable user experiences.

What are your responsibilities as a UX Designer?

A UX Designer is focused on all aspects of a product’s development, including design, usability, function, and even branding and marketing. Your work touches the entire end-to-end journey of a user’s interaction with a product. The primary role of your job includes identifying new opportunities for the product and business. This is your responsibility to make a product or service usable, enjoyable, and accessible. That brings us to the most important question:

So, Is UX Design a Good Career?‎

The importance of UX design cannot be overstated; not only for the end-user but also for the company or brand behind the user experience. According to, graphic designers earn yearly wages of $37,000 a year. While, UX designers earn a tidy sum of ‎$89,000 as compared to graphic designers ‎. From the perspective of the user, good UX design allows us to go about our daily lives as easily as possible. The ease with which we complete these actions, from setting an alarm to chatting with friends online, listening to music, or using a calendar app, is the result of good design.

What to expect?

As a UX designer, you must consider how to provide value to all types of users when creating these experiences.  You can accomplish this through the use of inclusive design, also known as universal or accessible design. According to reports, Covid-19 has increased internet usage by 70%. In the year 2020, there has been a 32% increase in app downloads and it was found out that users will not return to an app that provided a difficult user experience. Check out some innovative design tips here.

Exactly, why UX?

To begin with, UX design is a constantly evolving job sector that has expanded as a result of the current pandemic. If you want to work in a growing field with a lot of potentials, UX design is a ‎great career option with a lot of different perks.

More than half of mobile users abandon a website that takes more than three seconds to load. When you consider these facts, you can see how important the role of a UX designer is.

The significance of good (UX) design has long been recognized. There were also other job titles before information architects, such as usability specialists, product designers, and interactive designers. Surprisingly, all of these jobs had nearly identical tasks and requirements. So, user experience (UX) is not a new concept. The name, on the other hand, is new. UX Designers are in high demand in all industries. Click here to learn some useful webpage layout tips to reduce bounce rate.

Why was Abra application Built on the Litecoin Platform?

Presently, Abra seeks to use the Litecoin platform majorly for almost its transactions. According to the development team of Abra, Litecoin was chosen after an intensive and thorough research was carried out. The purpose of the research according to the team was to find a suitable platform that meets their criterias.LiteCoin Crypto

Litecoin being a fast, scalable, secure, off-chain, on-chain and low transaction and mining fee platform was chosen. Another reason why Litecoin was chosen was because of its strict adherence to the Bitcoin’s core published roadmap. Also, the Litecoin platform is free of network outages, hard fork drama and outrageous transaction fees.

The Abra development team knows that the Bitcoin is more secure than Litecoin. This means that the Litecoin will offer lower mining fees and scaling for users. Also, Litecoin was chosen because it offers lower transaction fees and the recent Litecoin update offers even lesser fees. Each transaction on the Litecoin platform is charged at as low as 1 cent.

What it Means for Litecoin:

Abra and Litecoin

Attribution: Image taken from

Abra was primarily designed to solve all the complexities involved in investing in different cryptocurrencies simultaneously. For users in the US, before they can begin using Litecoin, they have to first obtain Litecoin. This technically means that if more people in the US decide to use Abra, it will also mean an increase in the total number of Litecoin users. Also the use of Abra’s smart contracts will drastically limit the number of LTC tokens in circulation. The adoption of Litecoin by Abra also adds credibility to the Litecoin platform and it shows that Litecoin is one of the best cryptocurrency platforms out there.

How Can Abra App Wallets be Funded?

Wallets on the Abra application can be funded either through direct bank wires or transfers or through the purchase of Bitcoins. Users who decide to fund through the purchase of Bitcoins will be required to input only their phone numbers.

Users can fund using a Philippines or an American account. Express cards, Litecoin, Bitcoin, and Ethereum can also be used to fund the Abra application. Once your funds are confirmed by the Abra application, you can immediately begin investing in over 20 cryptocurrencies and 50 fiat currencies.

How You Can Use Abra?

For first timers, you have to download the Abra application from the apps official website. After downloading, you are expected to  write down the private keys. Since the Abra application is a non-custodial app, users can access their funds anytime they decide.


The team behind the development of Abra seeks to primarily create a stable platform that will encourage the storage of fiat currencies as well as cryptocurrencies.

At the onset, Litecoin CEO Charlie Lee promised users on the platform a huge surprise. This surprise must have at first looked confusing to the general public. The introduction of Abra is good cryptocurrency news both for the Litecoin platform and for the application itself.

The application also seeks to add more cryptocurrencies. Also, it is important to note that Abra does not allow users to own these currencies. They can only trade or transfer them. As earlier mentioned, the Abra will also help increase the total number of users of Litecoin.

The inherent benefits of the .net online tests

The best thing about ASP.NET is the sheer fact that it encompasses all the betterments of a Microsoft framework with the flexibility of working with it in any possible domain over any given frame of time. The basic approach has been the development and maintenance of rich sites and delivered it to corresponding clients. The applications, which can be crafted out of this technology, are leak proof and highly secure- the two most important things in the modern software industry. This is the sole reason why the individuals who have a good base on this platform are a rarity to find amongst many, who know it superficially.The inherent benefits of the .net online tests

Technical issues to withstand changes

The sheer number of people knowing this platform and the technology is a bane due to the unavailability of people who know it from the core. Therefore it is imperative from a recruiter stand point to ensure that the recruitment happens seamlessly and therefore the best person can be selected for the functional point of view. On most occasions, the recruitment process is a time consuming issue as it requires a lot of resource allocation as well as involvement from different people belonging to different domains. This therefore leads to selection flaws often, resulting in a deficit of knowledge base, the candidate comes with.

Requirement of conduction of the examinations

Herein starts the requirement of a dedicated online .net online test for the candidates coming in for interview in the company premises or remote locations. These tests are a necessity today owing to their own set of distinct requirement analysis and candidate exposure mapping. These may be custom made as per the requirements and therefore are suited for judging candidates coming in from different backgrounds for different nature of positions in the company associated. These tests also ensure complete insight into the candidate’s knowledge base, knowing him completely in and out before the next hiring step takes place.

Mapping of questionnaire to suit the necessity

The .net online test is mapped in accordance to the exact set of requirements the company requires from the candidates. These are therefore totally focused to obtain the aggregated score of the candidate who is scrutinized for each and every question which is included in the test concerned. Today, this is an absolute must due to the sheer volume of candidates it can handle at any given allocated time frame. This volume allocation is therefore a mandatory must to ensure that there are a lot of candidates to account for simultaneously to make up for the recruitment process in a tight time frame. This is again regulated as per the maximum number of people a company wants to recruit at any given interval of time as per the company parameters.

Knowledge base testing and related parameters

One of the most important parameter consistent with the online based tests is the sheer exposure validation of the candidate towards core system knowledge base. Therefore the basic competency of the candidate in terms of the chief job designation is the one which is paid the most leverage to in the tests. This achieves the best possible measure to ensure smooth operational recruitment as well as total exploitation of the candidate’s knowledge base to match the benchmarks set up by the company in terms of their own set of policies. These benchmarks are therefore set up in accordance to the new set of data coming in from the online tests and the next set of company policies are set accordingly to match the previous set of data.

Experts to help in domain case and question setting up

Experts to pertain to the specific domain in action are utilized in some occasions to mark the involvement of quality service in terms of online .net online test. These highly professional people are being utilized to ensure smooth functioning of the online test set up. Often these individuals are utilized to have a word with the company executives and to ensure the exact set of questions which best describes and denotes the business logic of the company in question. The questions are set up in accordance with the parameters which are pre-set to suit the exact nature of the candidate in question and also to ensure that the candidate knows the technology from depth and is completely industry focused in approach. The focused approach is often the rule setting as this makes and breaks a right candidate to be able to work in an organization which relies heavily on the employers.

Picking up the right candidate for the right kind of designation

ASP.NET is a great technology to work on. The involvement of the online based tests makes complete use of the raw knowledge base of all the candidates coming in for recruitment. The process also saves on invaluable time to ensure that maximum number of focused questions can be aimed at the candidates to judge their capacity of stress management and also test out their individual professional skill set. The reports which are henceforth obtained are then readily deported to the company executives, where they can further scrutinize the different parameters based on the marks obtained in the corresponding examination. These records can be furthermore used in the later stages to cater to the recruitment if future benchmarks for upcoming processes, neutralizing out the creases in the overall recruitment process to ultimately aim and recruit a candidate best suited for the concerned organization.

Best Introduction to Cryptography

Introduction to cryptography

Cryptography is a term that is derived from the Greek words “kryptos” meaning “hidden” and “graphein” which means “to write”. In other words cryptography involves hidden words or the study of information hiding and verification that includes the use of algorithms, protocols and strategies to consistently and securely delay or prevent access to sensitive information by unauthorized persons while enabling verifiability of all components in a communication. Cryptography allows people to transmit or store sensitive information over insecure networks such as the internet in way that it cannot be read by an unauthorized person except its intended recipient. This article is an introduction to cryptography with all that you need to know.

Main Goals of Cryptography:

Cryptography is used by security professionals for various reasons but the three main goals of cryptography include:

  • Data confidentiality
  • Data integrity
  • Data authentication

Confidentiality or data privacy is the most important goal of cryptography hence the meaning of a message is encoded to conceal it. The sender uses a cryptographic key to encrypt the message and the recipient also uses the same or a different cryptographic key to decrypt or decode the message.

Data integrity involves ensuring that the message received is similar to the sent message I.e it has not been modified or altered in any way. A unique message digest is created using hashing from the sent message and using the same technique, the recipient creates a second digest from the received message for comparison with the original one. This technique prevents unintentional alteration of a message but a variation will help in the creation of digital signatures to prevent malicious alteration.

Data authentication involves verifying that data actually came from where it claims to come from which is accomplished with the help of digital certificates.

Cryptography has implementation in many fields including the latest blockchain technology, you can find a good reference on blockchain technology following blockchain online course here.

How Cryptographic Keys Work?

Cryptographic KeysA cryptographic key is the most important part of a cryptographic operation since it is used to transform cipher text into plain text or vise versa with the help of a cryptographic algorithm. A cryptographic key is private ensuring secure communication. The security of a well designed cryptographic scheme entirely depends on how secure the keys used are. Cryptographic keys can be asymmetric or symmetric where symmetric encryption only requires one key while asymmetric encryption requires two different keys (One for encryption and the other for decryption). Public or private key pairs are provided by a certificate authority (CA) that uses the public key infrastructure.

Cryptographic Algorithm:

A cryptographic algorithm or a cipher is simply the means used to alter data from plaintext (readable form) to ciphertext or a protected form and vise versa. Altering ciphertext into plaintext is referred to as encryption whereas altering ciphertext into plaintext is referred to as decryption.

Why Cryptography Is So Important?

Cryptography is extremely vital in IT security in order to achieve data integrity, data confidentiality, non-repudiation as well as user authenticity. Using cryptography, data is protected from unauthorized access or theft. It can be easy to forge an email but it is difficult to corrupt a digitally signed email. Sensitive information remains secret especially when it is sent over insecure networks like the internet. When sending data to someone, it is easy to ensure that only the recipient can be able to decrypt your message.

I have tried to cover maximum about the basics of cryptography and hopefully the reader will have good understanding of the basics that can be further flourished using more related cryptography tutorials.

MicroServices Vs SOA

There has been a growing debate about the differences if any between Microservices and Service-Oriented Architectures (SOA). While both Microservices and SOA have more architectural similarities than differences, they are totally different from each other. These two architectures rely on services as their main component but in terms or service characteristics, they vary greatly. In order to distinguish between the two, it is important to first understand their architectural differences.Microservices Vs SOA

Microservices architecture is basically a particular way of developing mobile applications, web or software as independent suites of services known as microservices while SOA is a software architecture pattern allowing application components to offer services to other components over a network through a communications protocol.

Microservices Vs SOA

In Microservices architecture, there is very little or no coordination at all needed among services unlike SOA where coordination with multiple groups is required for creation of business requests. SOA facilitates component sharing while Microservices uses “bounded context” to minimize on sharing. A bounded component in this case means the coupling of a component as well as its data into a single unit that has minimal dependencies. Systems that are built on SOA are more likely to be slower than those built on Microservices since SOA solely depends on multiple services in order to fulfill a business request.

SOA has a messaging middleware that offers several additional capabilities that are not present in Microservices such as message enhancement, mediation and routing as well as message and protocol transformation. On the other hand, Microservices consists of an API layer that is between services and service consumers. The architectures of SOA depend on messaging (MSMQ, AMQP) as well as SOAP as the primary remote-access protocols while most Microservices architectures only rely on two protocols namely simple messaging (MSMQ, JMS) and REST. Microservices has a protocol that is usually homogeneous in nature. However, SOA promotes multiple heterogeneous protocols through the messaging middleware component.

Microservices basically tries to simplify the architecture pattern through reduction of the choices for integration thus if you need to integrate many systems with different protocols in a heterogeneous environment, then SOA should be your choice. But if your services can be exposed and accessed via the same remote-access protocol, Microservices is a better choice. You can easily find many Online Certificate Courses on Microservices and SOA here. One of the most fundamental capabilities offered in SOA is contract decoupling which offers a high level of decoupling between consumers and services. Microservices on the other hand does not offer contract decoupling.

Nothing really new was introduced in Microservices architecture but it is basically a logical evolution of service-Oriented Architectures (SOA). For more complex and large business application environments that may need integration with several heterogeneous applications, SOA will be better suited. However, using SOA patterns to implement workflow-based applications with a well-defined processing flow may be a bit challenging. Equally, small applications may also not be well suited for SOA since they do not require messaging middleware component but the Microservices pattern is a perfect choice for well-partitioned and smaller web based systems. Microservices lacks messaging middleware, a factor that makes it unfit for large and more complex environments.

If you are looking to develop an application with greater control, then Microservices is a great option but as your business grows, you might need more capabilities like heterogeneous systems integration or complex request transformation where you may be required to switch to SOA pattern.
