Disclaimer: chiccocoin is not a true cryptocurrency and we do not sell it , this article is for recreational / educational purposes only Every day on our feeds we find news about new cryptocurrency or someone who says that they are a big bubble that will soon explode and of which only the blockchain will remain. But, what is the blockchain?By definition : Is a continuously growing list of records, called blocks, which are linked and secured using cryptography. So, the blockchain is an immutable, sequential chain of records called Blocks. Each block can contain transactions, files or any data you like. The important thing is that they’re chained together using hashes .Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance . This makes blockchains potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing or voting. How does a blockchain technically work? Understanding Blockchains reading article or tutorials isn’t easy. Wandering among the many online guides I found this article by Daniel van Flymen and my curiosity to understand how it really worked has grown so much to try to create a blockchain using NodeJS. 1. Create a logo The first step to creating a new project is to create the logo. It makes everything real. To do this I used Squarespace logo creator and this is the result:Now we can really start with our project. 2. Start with Express To facilitate the creation of the APIs to interact with the blockchain I started the project directly with...
June 24, 2017 Well, app development was never a lethargic process, and now with the advent of RMAD tools and low or no code app development, the process is like a house on fire. There would be wild thought running around your mind that with already 2.2 million mobile apps existent in the Apple store and 2.8 million apps in the Google play store why is there wave of the rush for Android and iPhone app development? The answer lies in the revenue hidden in this market. Let’s introduce you to the figures of app revenue that are driving more and more developers to gear up app development process. Back in the year 2015, the total revenue of this app development was 69.7 billion US dollars. Now, the projected app revenue for the year 2020 is expected to be 188.9 billion US dollars. The hype in revenue is due to in-app advertising and app stores. This is what driving the developers to develop apps even when there is a massive amount of competition. An individual spends on an average 5 hours, a massive time period of 5 hours, you see. If you are a business owner, you can have access to these 5 hours of users time and engage customers through it. Out of this 5 hours, half of the time is engaged in social media, messaging and entertainment apps. What you are left with is the rest half to attack. Several startups and iPhone and android app development companies do recognize this emerging trend and try to cope with the same but they take an extremely outstretched time...
Portarlington-based independent TD Cathal Berry says that the position of the National Cyber Security Centre (NCSC) has been vacant for more than a year because the salary isn’t sufficient to attract a suitable candidate. Deputy Berry, who is a TD for the Kildare South constituency that also includes Portarlington, Killenard and Ballybrittas, is a former Deputy Commander of the Army Ranger Wing, and has hit out the limitations of the NCSC following the cyber attack on the HSE and the Department of Health. “You’re looking at the head of IT security for Ireland being paid €89,000 so they couldn’t get someone to take a job,” he said in an interview with the Irish Times. “(The NCSC) is supposed to be kicking ass when it comes to all the other Government departments so you’d expect someone to have the appropriate status so they can interact with secretaries general across the Government service”. “Our capability is improving but it is still very limited,” he added in a statement. “The capacity of the National Cyber Security Centre needs to improve on three fronts – premises, budget and staff. “It’s incredible that we still don’t have a dedicated premises yet and their budget of €5 million a year is not sufficient. 2Most importantly, from a talent perspective, we need to improve the amount of people there. “There is currently only 25 people on the staff and the appointment of the Director of the National Cyber Security Centre has been vacant for the last year.” Deputy Berry added that “the National Cyber Security Centre was intended to be a multi-agency entity with the support...

In this article, I want to share with you a different way to build Ruby on Rails applications. I call it the Modular Way, and the main idea behind that name is to separate your application into small and reusable modules thanks to Rails engines. If you’ve been working with Ruby on Rails, you know how easy it is to create a basic application thanks to the ‘conventions over configuration’ concept. After a while however, it’s usually not enough anymore. The quick and simple application that was created to get an MVP out ASAP is not up to the task and requires changes. People then start to think about ways to optimize their application. But this might not actually be needed. Let’s say the application, whatever it is, is doing well in its niche. It’s not the new Facebook or Twitter but revenue is there and people like the product. The good news is that the concept is good and could be reused in other industries, however not every industry has the same needs. How about we separate the code into smaller components? We would be able to plug or unplug any feature with this solution. We could then use those components in different applications. The tricky part is how we end up separating the source code. The best way to do this is to encapsulate each feature in its own module. That probably sounds quite abstract. Let’s dive in and learn more about modular applications. 1. Monolithic Applications A monolithic application, like the name says it all, is an application built in one block. Basically, like a monolith....
