Professor, Osaka University Yoshiki Sawa describes your plans for the treatment of heart failure in 2017 Pluripotent stem cells – iPSC – possess limitless potential in the world of regenerative medicine. One of the many possibilities of their application can be recovery of patients with hearts that soon will be first tested in clinical trials on humans in Japan. From the moment of their receipt in the laboratory Signa Yamanaka of Japan in 2006, the potential of iPSC has been studied many times. We have seen how their implanted rabbits to restore vision, used in the treatment of brain tumors and transformed cells predecessor. Read more →

Recently one of my friend had an unpleasant incident. His son was doing school homework in computer science, but the result of his labors was gone. Child used as storage media USB-stick, which was a company logo of my friend, and it is in this drive was the problem. If this case were isolated, it could skip past, but among the specialists in data recovery such drives ("branded"; they are called "gift") – has long been hackneyed problem. As your branded USB drive have done my friend? Ordered online meets the parameters of the device with more or less meets brand design (this is important), and ordered the printing firm drawing on the General description for that order of the stick the desired figure. It seems to be easy, but ... the desire to save money has...

If you are exploring the web recently, but have already seen various nice effects on the website, the type of particle system, or any game developed on canvas'e and you are intrigued, but learning something new is very scary, I'm ready to show you how in 50 lines of js code you can do something interesting on canvas'e. I have to Say, I want to explain the logic of working with canvas'ohms. The code is very simple, I hope it will encourage you to study such tools as canvas. And this is a very good practice for a beginner JS programmer. let's Move on to the code. Let's write a simple generation of squares of different colors on the canvas. The code you can see all at once, then I will explain it. What we need to do? Read more →

No matter beginner or professional, convenient programming tools are important for any person who wants to write code productively. I have prepared a small selection of useful tips, tricks and extensions for the web developer. Improved appearance 1. Material Theme & Icons It's just a beast in themes VS Code. I think the material topic is the closest to writing with a pen and paper in the editor (especially when using a low contrast themes). Your editor looks almost smoothly, moving from built-in tools to the text editor. Imagine the epic theme combined with epic icons. Material Theme Icons is a great alternative to replace icons VSCode by default. Large catalog icons seamlessly fits into the theme, making it more beautiful. This will help you easily find...

Older devices, laptops and desktops, need to be considered in the context of the private wishes of the youth or of the peculiarities of the then market computer-related iron. It is not easy, but when trying a simple collection of gadgets is expanding at the present archives. However, in my case this is just a nice bonus. For example, my excursion into the world of audio cassettes has led to the emergence of a box of strips, which in the nineties were recorded jazz programs European radio. That's who wrote them? And why? the Result of a recent study from MD was hundreds of carriers with heavy metal music, someone once collected and decorated on the highest level. This is a live examples of usage of a device or format. To recreate in the mind the situation of...

I guess almost everyone has faced a situation when a mobile operator has connected any subscription to your phone number, but you were definitely sure that nothing is connected. And who in their right mind would connect, for example, "the Horoscope 9P/day" (280R/month), when the Internet is full of horoscopes for any taste, and sometimes 280R is the entire budget expenditure for mobile communication per month? Often people just switch off the subscription appeal is sometimes made to the operator and ask to return the money (with varying degrees of success). But what affects the likelihood that you will connect subscription which you are connected? Read more →

Originally created to organize communications within companies, this modern platform is currently able to not only provide employees access to email, calendar and other collaboration tools, but can also perform several other tasks. For example, such platforms are often given the task of managing certain resources of the enterprise. Let's look at how the functionality of resource management is implemented in Zimbra Collaboration Suite. Read more →

When it collected reports on the vote to participate in a specialized conference, I wanted to tell a topic – how to unseat the Director of quality. It would be a circumstantial report about the career growth for a programmer or it Director. on the one hand, the growth in the direction of the Director of quality seems strange – it's like a completely different area. But, as we all know, the programmer can grow a lot of interesting things. It is not only I say this idea sounds more and more. For example, at the same conference another year there was a report on this subject — both in the West CIOs go to operations management that is not associated with it. the Subject of quality management, personally I think incredible, just incredibly interesting and...

Imagine a time when each of the light bulbs in your home will be a source of Internet. Imagine the scenario when, after standing under the lamp for only one minute, you would have downloaded about 5 movies in HD. It sounds cool, right? But thanks to the technology Li-Fi, this dream can become a reality. Using this technology we can rethink the role of light itself. What is Li-Fi? Li-Fi — a system of visible light communication (VLC) which uses light to send wireless data embedded in its beam. The device supports Li-Fi converts the light beam into an electrical signal. Then the signal is converted back to data. This term was coined by German physicist Harald Haas (Harald Haas) during a TED Talk in 2011. He foresaw the idea of using light bulbs as wireless...

This weekend I had some free time between classes (approx. the author at the time the article received a master of science degree), and I decided to go back to the creation of shaders, think of this postprocess effect scanning. I imagined that he used the game as a kind of effect scanning at a distance. We also use some simple distortion noise, so the effect looked a little more interesting. In this article I will describe how to implement this effect in UE4. There are several ways through which you can create this effect. One of these methods was chosen. If you're interested, welcome under kat

* Link to library in the end of the article. In the article the mechanisms implemented in the library, with medium detail. Implementation for macOS is not yet finished, but it is not much different from the implementation for Linux. Here mainly discusses the implementation for Linux. github walking around one Saturday afternoon, I came across a library that implements the updating of c++ code on the fly for windows. I myself climbed down from windows few years ago, haven't looked, and now all programming takes place either on Linux (at home) or macOS (on the job). A little googling, I found that the approach of the libraries above are quite popular, and msvc uses the same technique for the function "Edit and continue" in Visual Studio. The only problem is...

Hi, Habr! All like runtime exceptions. There is no better way to learn about something was not considered when writing the code. Especially if the exceptions you have millions of users, and this news comes a panic email om with portal Analytics. Saturday morning. When you're on a country trip. After such seriously think about error handling — what opportunities does our Kotlin? First comes to mind is try-catch. For me — a great option, but it has two problems: This is after all unnecessary code (a necessary wrapper around the code, not the best way affects the readability). Not always (especially when using third-party libraries) from within a catch block possible to get an informative message about what exactly caused the error. Let's see what try-catch...
