Wearable tech devices, such as smart watches and bracelets, have firmly stepped into our everyday life and accompany us in different spheres of life. And who knows, we may soon witness the next tech revolution in the wearable world.
Microsoft Research and MIT Media Lab PhD students have teamed up to create the next level of wearable: temporary smart tattoos.
The technology is named DuoSkin. These tattoos consist of artistic arrangements of conductive gold and silver leaf, plus tissue-thin electronics. Users can apply the tattoo to their body with a wet cloth, similar to any other temporary tattoo.
The fabrication process is fairly simple: first, you design a stencil with any graphic design software, and cut the pattern out of tattoo paper and vinyl. Then you place the gold leaf layer on top to create conductivity, and attach surface-mount electronics.
Smart tattoos can be used for several purposes. Firstly, the tattoo can act as an interface that can be used, for example, as a trackpad or a button to remotely control devices. It may be quite demanding in the near future as our devices get smaller and smart tattoos could provide some additional auxiliary area, without carrying a larger device. Secondly, they can track and show users information about themselves, for example they can change color depending on the user’s mood or show body temperature. A third possible function is wireless communication. The tattoo could include an NFC (near field communications) tag, an electrical component that includes small microchips to store data that can be read by phones or other NFC devices nearby. In the near future, the technology could serve as a substitute for identification, subway cards, etc.
Cindy Hsin-Liu Kao, the lead researcher, calls DuoSkin a “project” and not a product or prototype. Others may use this information as a basis to create their own personalized on-skin wearables.
Lets’s think a bit out of the box:) The future presented in some fantastic films is about to come to reality: not more physical devices but different tattoos and built-in chips:) Аnd what do you think about smart tattoos? Will they change the wearable world or will soon be forgotten?

For almost 15 years ASP.NET has been one of the best web development technologies and many developers consider it to be the best offering from Microsoft. ASP.Net evolves to bring in better features and functionality, which helps businesses scale better. Each year developers see few new trends that enhances development and shortens the time-to-market the solution. Here we will discuss a few trends that will benefit both developers and businesses indulging in ASP.Net.
Let’s have a glimpse at it benefits.
Data Flow in One Direction – Properties are passed to component to render HTML tags. Component itself cannot change the property; instead, it requires a callback function to modify the property values.
Easy to Integrate – React can be simply integrated with other tools or frameworks like Jest, Angular.js or Backbone.js.
Xamarin is highly popular mobile development framework with the rule write-once-run-everywhere coding for three leading mobile platforms: Windows, Android and iOS. It empowers developers to write in a single language on a single code base for their app to reach over billions of smart devices irrespective of the platform. Xamarin delivers perfect look and feel of any given platform’s native UI with power-packed functionality and native app performance. Xamarin eliminates the need to manage separate development teams or having to choose one platform over another.
Following are few more benefits of Xamarin:
Xamarin uses the C# programming language
C# is capable of doing anything you could do in Java, Objective-C, and Swift – and it works on platforms that use any of these. Most applications can share 75% or more of their coding, helping to make development on multiple platforms easier than ever before. Many functions unique to each device are mapped at runtime to correspond to that specific device, resulting in an end-user experience that works the way they expect it to work.
Xamarin can import and convert existing code
Do you have existing Objective-C or Java code? Xamarin uses an automatic binding generator to match code like custom controls and frameworks to your new app, and a little bit of testing is usually enough to fix any glitches that occur. By importing your existing code, you can hit the ground running and reduce the time it will take to roll out your improved app.
Xamarin offers same-day support for new OS releases
One of the biggest problems with apps is updating them when a new operating system comes out. These changes can cause major disruptions in the way some functions work, but this particular developer has been able to offer same-day updates that allow you to start taking advantage of new features and capabilities. These updates also mean that you can deal with any major disruptions to your app and get it back up and running if anyone was broken – your business can’t afford to have its tools stuck in limbo, and working with a company offering active support is one of the best ways of ensuring your investment won’t be lost at a crucial time.
Elasticsearch is the most popular enterprise search engine followed by Apache Solr based on Lucene. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Elastic search was first released in February 2010, and is a free and open source distributed inverted index created by Shay Banon. It is developed in Java, so it is a cross-platform.
Below you can find major highlights of Elastic Search:
Real-Time Data Analysis – All data is immediately made available for search and analytics.
Distributed approach – Indices can be divided into shards, with each shard able to have any number of replicas. Routing and rebalancing operations are done automatically when new documents are added.
Multi-Tenancy – Multiple indices can be maintained by single cluster and can execute queries individually or as a group. Also, maintain alias of indices and keep them updated.
Full-Text Search – Elastic Search implements a lot of features: customized splitting text into words, customized stemming, facetted search, and more. Powerful, developer-friendly query API supports multilingual search, geolocation, contextual did-you-mean suggestions, autocomplete, and result snippets.
Easy-To-Use RESTful API – Elastic Search is API driven; actions can be performed using a simple Restful API.
Open Source – Elasticsearch is available freely, under the most adoptable and trusted open source license of Apache 2.
In addition, the Microservices, Azure, and AngularJS are also trending in Asp .Net. Nowadays, enterprise applications are in high demand, and these tools are playing a key role to hit the ground and running.

Introducing ASP.NET Core:
ASP.NET Core is a new open-source and cross-platform framework for building modern cloud based internet connected applications, such as web apps, IoT apps and mobile backends. ASP.NET Core apps can run on .NET Core or on the full .NET Framework. It was architected to provide an optimized development framework for apps that are deployed to the cloud or run on-premises. It consists of modular components with minimal overhead, so you retain flexibility while constructing your solutions. You can develop and run your ASP.NET Core apps cross-platform on Windows, Mac and Linux. ASP.NET Core is open source at GitHub.
The framework is a complete rewrite that unites the previously separate ASP.NET MVC and Web API into a single programming model.
Despite being a new framework, built on a new web stack, it does have a high degree of concept compatibility with ASP.NET MVC.
ASP.NET Platform exists for more than 15 years. In addition, at the time of System.Web creation it contained a large amount of code to support backward compatibility with classic ASP. During this time, the platform has accumulated a sufficient amount of code that is simply no longer needed and is deprecated. Microsoft faced a difficult choice: to abandon backward compatibility, or to announce a new platform. They chose the second option. At the same time, they would have to abandon the existing runtime. Microsoft has always been a company focused on creation and launch on Windows. ASP.NET was no exception. Now the situation has changed: Azure and Linux occupied an important place in the company’s strategy.
The ASP.NET Core is poised to replace ASP.NET in its current form. So should you switch to ASP.NET Core now?
ASP.NET Core is not just a new version. It is a completely new platform, the change of epochs. Switching to ASP.NET Core can bring many benefits: compact code, better performance and scalability. But what price will be paid in return, how much code will have to be rewritten?
.NET Core contains many components, which we are used to deal with. Forget System.Web, Web Forms, Transaction Scope, WPF, Win Forms. They no longer exist. For simple ASP.NET MVC-applications changes will be minor and the migration will be simple. For more complex applications, which use a great number of .NET Framework classes and ASP.NET pipeline situation is more complicated. Something may work and something may not. Some part of the code will have to be rewritten from scratch. Additional problems may be caused by WebApi, because ASP.NET MVC subsystems and WebAPI are now combined. Many libraries and nuget-packages are not ready yet. So, some applications simply will not have a chance to migrate until new versions of the libraries appear.
I think we are waiting for the situation similar to the transition from Web Forms to ASP.NET MVC. ASP.NET Framework will be supported for a long time. First, only a small amount of applications will be developed on ASP.NET Core. Their number will increase, but sooner or later everyone will want to move to ASP.NET Core. We still have many applications running on the Web Forms. However, no one comes to mind to develop a new application on the Web Forms now, everybody chooses MVC. Soon the same happens to ASP.NET Framework, and ASP.NET Core. ASP.NET Core offers more opportunities to meet modern design standards.
The following characteristics best define .NET Core:
- Flexible deployment: Can be included in your app or installed side-by-side user- or machine-wide.
- Cross-platform: Runs on Windows, macOS and Linux; can be ported to other OSes (Operating Systems). The supported OSes, CPUs and application scenarios will grow over time, provided by Microsoft, other companies, and individuals.Command-line tools: All product scenarios can be exercised at the command-line.
- Compatible: .NET Core is compatible with .NET Framework, Xamarin and Mono, via the .NET Standard Library.
- Open source: The .NET Core platform is open source, using MIT and Apache 2 licenses. Documentation is licensed under CC-BY. .NET Core is a .NET Foundation project.
- Supported by Microsoft: .NET Core is supported by Microsoft, per .NET Core Support.
- As for the “cons” one of the biggest issues are gaps in the documentation. Fortunately most of the things for creating and API are covered, but when you’re building an MVC app, you might have problems.
- Next problem – changes. Even if you find a solution to your problem, it could have been written for a previous version and might not work in the current one. Thanks to open source nature of it, there is also support available on github. But you get same problems there (apart from searching).
- Another thing is lack of support in the tooling. You can forget about NCrunch or R# Test Runner. Both companies say they will get to it when it gets more stable.
- ASP.NET Core is still too raw. Many basic things, such as the Data Access, is not designed for 100%. There is no guarantee that the code you are using now will work in the release version.
- It’s modular. You can add and remove features as you need them by managing NuGet packages.
- It’s also much easier and straightforward to set up.
- WebApi is now part of the MVC, so you can have class UserController, which will return a view, but also provide a JSON API.
- It’s cross-platform.
- It’s open-source.
ASP.NET Core is the work on the bugs of the classic ASP.NET MVC, the ability to start with a clean slate. In addition, Microsoft also aims to become as popular as Ruby and NodeJS among younger developers.
NodeJS and ASP.NET have always been rivals: both – a platform for backend. But in fact, between them, of course, there was no struggle. The new generation of developers, the so-called hipster developers, prefer Ruby and Node. The adult generation, people from the corporate environment, are on the side of .NET and Java. .NET Core is clearly trying to be more youthful, fashionable and popular. So, in future we can expect the .NET Core and NodeJS to be in opposition.
In its advertising campaign, Microsoft is betting on unusual positions for it: high performance, scalability, cross-platform. Do you think that ASP.NET “crawls” on the territory of NodeJS? Please feel free to share your thoughts with us.
Thank you in advance!

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.
