12 Fractured Apps and Docker

1 year, 1 month ago
For these years I became the witness of how more and more people support the manifesto 12 Factor App and begin to implement the provisions described there. It led to emergence of applications which were considerably simplified in expansion and management. However examples of practical application of these 12 factors were quite unusual occurrence on Internet open spaces.


During operating time with Docker, benefits of 12 Factor App (12FA) of steel for me more notable. For example, 12FA recommends that logging was configured for standard output and it was processed as the general event stream. You sometime used command docker logs? It also is 12FA in operation!

Erlang for web development (1)-> Acquaintance;

1 year, 1 month ago

I begin to publish a series of articles about web development on the Erlang. Many want to try the Erlang, but face a problem that introduction courses generally concern the Erlang as functional language and are far from real projects (Learn You Some Erlang for great good! — good and detailed book). On the other hand all training materials on web development mean that the reader already well knows the Erlang.

This series of articles is calculated for developers who have an experience in web development (PHP, Ruby, Java), but have no experience of development on the Erlang.

Task will be to make the blog. At a code from the articles https://github.com/denys-potapov/n2o-blog-example, the ready project it is possible to look to the address http://46.101.118.21:8001/. Features of the project:
  • updating of comments in real time;
  • authorization through Facebook;
  • we store data in mnesia.

At the heart of the project feymvork n2o. The choice is quite subjective, but from live the Erlang of frameworks, n2o me seemed to most "erlangopodobny", in too time of ChicagoBoss is more similar to MVC frameworks in other languages.

To Rasparsit HTML in .NET and to survive: analysis and comparison of libraries

1 year, 1 month ago

During work on one house project, faced need of parsing of HTML. Search in Google issued kommenariyaAthari and its micro overview of actual HTML parsers in .NET for what to it many thanks.

Unfortunately, no digits and/or arguments for benefit of this or that parser were found that was the cause of writing of this article.

Today I will test popular, at the moment, libraries for work with HTML, namely: AngleSharp, CsQuery, Fizzler, HtmlAgilityPack and, of course, Regex-way. I will compare them on the speed of work and usability.


TL; DR: The code of all benchmarks can be found on github. In the same place results of testing lie. The most actual parser at the moment is AngleSharp — the convenient, fast, youth parser with convenient API.

That to whom the detailed overview — welcome under kat is interesting.

Development on Yii2 framework on the IBM Bluemix platform

1 year, 2 months ago
I had difficulties with placement of PHP-applications with use of a framework of Yii2 on the IBM Bluemix platform. It is sure, I such not one therefore this post contains the short instruction as these difficulties can be avoided.

That we will need to make:
  1. to create the project in Bluemix
  2. to connect Git
  3. to create the Yii2 project and to change a file structure
  4. to configure a cloud
  5. to include the application, having filled in a code

We create the application in Bluemix


Bluemix on the structure is intended for the final product, thus it is necessary to be engaged in development of the project locally or (as I) on the separate server.

After registration for bluemix.net we come on DASHBOARD and we create an environment for the application for php in Cloud Foundry. For this purpose on a homepage we click Create App.

The field of activity of our company extends far beyond game development. In parallel with it we keep tens of internal projects, and Player Relationship Management Platform (PRMP) – one of the most ambitious.

Java instead of Groovy

1 year, 2 months ago
Suddenly it turns out that in the project scripts are necessary and there is a question what evolution or revolution is better?
But even attempt to implement gruv can fail in legas the project with conservative collective. And the manual can find ten more of the reasons not to pass a gruva in the project. Though groovy is much simpler and closer to the programmer to aware java, than the same scala.



But even in this case it is possible to use dynamically compiled scripts in the project. Let's learn to compile java a code dynamically in memory and to start it in jvm, to use in it dynamically loaded libraries from maven. It would be desirable to write as little as possible code for this purpose and that process of use was simplest. And still our pogramma would not like to hope for availability of tools.jar.
