But why TypeScript?
Let’s review main reasons of its popularity:
- TypeScript can be just the right fit for projects in which developers try to remain relevant without the need to learn a whole new syntax.
- TypeScript has many additional language features but defining types and creating classes, modules, and interfaces are some of the key features it offers.
- TypeScript implements many conceptions that are appropriate to object-oriented languages such as extending, polymorphism, encapsulation, accessibility modifiers and so on.
- Lots of TypeScript features have strict rules, so various code formatting errors are excluded. Which means that the possibility of incorrect implementation or inaccurate method invocations is eliminated.
TypeScript has a number of other positive features that are out of the scope of this article. On the other hand, there are two significant minuses exist.
- Probably, the biggest minus is entry threshold and number of specialists on the market. Nowadays there are not so many specialists with solid experience in this language.
The most recent version, TypeScript 1.8, rolled out in February, includes several more features like F-Bounded polymorphism, string literal types, etc.
We will be happy to hear how you use TypeScript in your current projects, if you like it, if you are planning to switch to this language, what are the pros and cons in your opinion, etc. Feel free to share with your thoughts in comments below!

Facebook is not the only one to use React:
Instagram is 100% built on React, both public site and internal tools ;
Yahoo`s mail client is made in React;
Netflix – the biggest paid video-streaming service;
Sberbank, bank #1 in Russia, is built with React;
Khan Academy uses React for most new JS development.
React in comparison to Angular.js isn`t a complete framework. However we can`t say that React.js is only “V” in the MVC. After a closer look, you can actually see that React.js is more than just “V”, it has quite some features of the C (controller) part as well. This is why React is so confusing to understand.
Let`s see why React.js stands out from the crowd:
Flux – is highly competitive to MVC. One-way data flow provides maintainability and efficient arrangement of data and DOM elements.
React developers suggested using “virtual DOM” in order to solve performance issue for websites with too dynamic DOM. All changes in a document are made there first, and then React looks for the shortest path to apply them in a real DOM tree. This approach makes the framework fast.
React is fundamentally different than other front-end frameworks in that each asset is made up of many isolated components. Want a button changed across the whole platform? Change it once and voilà it`s changed everywhere.
By making the creation, distribution and consumption of isolated reusable components more straightforward, developers are better able to save time by using and creating common abstractions. This is true of both low level elements like buttons and high level elements such as accordions.

First there existed e-cash, which then grew into Bitcoin. Since then an entire new world of currency has emerged known as crypto currency, which is a virtual, decentralized currency system that actually only exists as a computer file with transactions recorded in a ledger. It’s an Internet-based system of money that goes beyond traditional currency exchange and offers a global system that can be used by everyone for buying products and services here and there and everywhere.
No question Bitcoin has been capturing the world very fast. Still although Bitcoin is the pioneer and beyond all doubt the most popular ‘crypto currency’, it is not the only one. A number of other crypto currencies are appearing thus offering alternatives and are just as valuable and actively traded. Below there are some examples of this crypto currency:
So there are a number of alternatives to Bitcoin that are competing for attention. Perhaps not all of them could move forward, but the idea is that many people and businesses all over the world are step-by-step becoming accustomed to the concept of a new type of currency. The idea of crypto currency is no doubt catching on as more people to see the potential for how it can be used to the local and global economies.
How do you feel about the concept of crypto currency and what future do you predict for it? Which crypto currency in your opinion does deserve attention except for Bitcoin? I’ll be glad to hear your thoughts in the comments below.

Over the years, PHP has evolved greatly and now it’s not just the most popular server-side scripting language but also the language used to build complex websites and web apps. The same could be told about its frameworks. PHP web frameworks have an ecosystem of their own in the world of web development. PHP frameworks are used to build websites and web applications of all sizes and complexity, ranging from small static websites to large scale complex enterprise content management systems.
Still there are different opinions on the question which PHP framework is the best, as some developers prefer performance, some prefer better documentation, some prefer lots of built-in functions, etc. Perhaps we should have a look at the frameworks depending how popular they are.
Different frameworks have been popular in different time. For instance, CodeIgniter framework remained the top choice for PHP developers from 2011 to mid 2014. However, later in 2014 a new PHP framework Laravel has gained its popularity and became the most used framework in 2015. Now in 2016 it is clear that the Laravel framework will remain at the top, due to the huge interest from developers and clients worldwide.
It’s already been said that Laravel is most famous PHP frameworks nowadays. It is very secure and have a lot of useful libraries like session, authentication, middleware, RESTapi and others are included in it. PHP developers choose to work on the Laravel framework because its large and gradually growing community and very good functionality. You don’t need to write more code because every basic and required code-blocks are pre-build on it. At the same time it’s mostly used by experts.
– Routing and middleware are the best feature of Laravel
– Laravel uses the blade template engine for generating various views
– Inherent Database Version control
– Built-in unit testing and simply readable impressive syntax
– Larger Community catering to thousands of progarmmers
CodeIgniter is the second most popular web framework among PHP developers. It is a lightweight powerful PHP framework that provides simple and elegant platform to create full-featured web applications. Choosing CodeIgniter you get all the tools you need in one little package. It’s easy to understand and to extend.
– Develop using MVC pattern
– No PHP Version Conflicts
– Less Duplication of Code
– Most Active Online Community
– Cache Class
– Security and Encryption
– Little to no server requirements
YiiFramework is the high-performance modern PHP framework. It attracts most of PHP developers due to its features like fast development, caching, authentication and role-based access control, scaffolding, testing, etc.
– Yii adopts the proven MVC architecture
– Yii allows developers to model database data in terms of objects and avoid the tedium and complexity of writing repetitive SQL statements
– With the help of Yii, collecting input extremely easy and safe
– Zero configuration required to let the task easier for you
– Thorough maintenance
CakePHP is also popular among PHP developers due to its lightweight, simplicity, faster and require less code. It is easy to learn with fast and flexible templating. The built-in CRUD feature is very handy for database interaction. The framework also has various built-in features for security, email, session, cookie and request handling. It’s perfectly suited for commercial applications.
– MVC Pattern – Model support data handling, with the model class you can insert, update, delete or read the data from the database.
– ORM features, converting data between incompatible type systems in databases and object-oriented programming languages
– Proper class inheritance
– Easily extend with Components, Helpers, Behaviours, and Plug-ins
No doubt, Symfony is a stable and sustainable PHP framework. It is a flexible, scalable yet powerful. It has a huge community of Symfony fans committed to take PHP to the next level. Symfony has plenty of reusable PHP components that can be used like security, templating, translation, validator, form config and more. It’s easy to install and configure on most platforms and it’s database engine-independent.
– Based on the premise of convention over configuration–the developer needs to configure -only the unconventional
– Compliant with most web best practices and design patterns
– Enterprise-ready–adaptable to existing information technology
– Stable enough for long-term projects
No doubt, some of our readers will either agree, disagree or have other PHP Frameworks, which they consider the best. But that’s already nice that you’ve read this post and perhaps could contribute to it. So please feel free to add a comment or through light why this or that framework is so popular and why it should or shouldn’t be
Programming cells may soon become as easy as programming a computer. Just as computer software designers create programming for computers, scientists have created a programming language that allows them to design DNA-encoded circuits that can give new function to living cells.
Using this language, anyone can write a program for the function they want, such as detecting and responding to certain environmental conditions. They can then generate a DNA sequence that will achieve it.
“It is literally a programming language for bacteria,” says Christopher Voigt, an MIT professor of biological engineering. “You use a text-based language, just like you’re programming a computer. Then you take that text and you compile it and it turns it into a DNA sequence that you put into the cell, and the circuit runs inside the cell.”
In the new software — called Cello — a user first specifies the kind of cell they are using and what they want it to do: for example, sense metabolic conditions in the gut and produce a drug in response. They type in commands to explain how these inputs and outputs should be logically connected, using a computing language called Verilog that electrical engineers have long relied on to design silicon circuits. Finally, Cello translates this information to design a DNA sequence that, when put into a cell, will execute the demands.
The good thing about it is that it’s very simple, without many of the intricacies often encountered in programming.
“You could be completely naive as to how any of it works. That’s what’s really different about this,” Voigt says. “You could be a student in high school and go onto the Web-based server and type out the program you want, and it spits back the DNA sequence.”
For now, all these features have been customized for the E. coli bacteria, one of the most common in studies, but researchers are working on expanding the language to other strands of bacteria.
Using this language, they’ve already programmed 60 circuits with different functions, and 45 of them worked correctly the first time they were tested – which is a remarkable achievement. The circuits were also strikingly fast, and the whole process promises to revolutionize DNA engineering. Before, it could take months or years to design such a circuit. Now, it can be done in less than a day.
Dr. Voigt’s team plans to work on several different applications using this approach — bacteria that can be swallowed to aid in digestion of lactose; bacteria that can live on plant roots and produce insecticide if they sense the plant is under attack; and yeast that can be engineered to shut off when they are producing too many toxic byproducts in a fermentation reactor.
What do you think about this rapidly developing revolutionary computer industry? Can it replace drugs and medicine in future? Can it help to cure cancer and AIDS? Will it make a living cell immortal?
