Project Arena - webinar for the creators of serious VR-projects  
 
Webinars are no longer surprising, and there are plenty of places to learn on the Internet. However, even among such an abundance there are activities that I want to tell you about separately - and this is the announcement of one of them. With pleasure we inform you that May 16 will be a webinar dedicated to Project Arena - a large-scale demonstration VR-project for training developers.
 
here . Speakers at the event will be Rudy Cazabon, a consulting engineer for Intel and Rod Recker, a well-known expert in computer modeling.   Webinars are no longer surprising, and there are plenty of places to learn on the Internet.

Antipatterns testing software

Antipatterns testing software

Introduction


 
There are several articles on the antipatterns of software development. But most of them talk about the details at the code level and focus on a specific technology or programming language.
 
 
In this article, I want to take a step back and list the high-level antipattern testing common to all. I hope you will learn some of them regardless of the programming language.
 
 

Terminology


 
Unfortunately, the testing has not yet developed a common terminology. If you ask a hundred developers what the difference between an integration, cross-sectional and component test is, you'll ...[/h][/h]

Not a single code: what affects the work of the block-system

Block-network - a structure that consists of a set of parts that constantly interact with each other. Understanding the work of this complex mechanism is impossible without a comprehensive analysis of its components, their dynamics and structure. In this article, we will talk about the different types and levels of management of block systems, as well as their main components.
 
 
Not a single code: what affects the work of the block-system
 
 

Control levels


 
Most decentralized applications based on the blockbuster have several related management levels:
 
 
 
Internet protocols - for example, the TCP /IP protocol;

Experience in creating a mobile application: it was not the first time

We have just finished our series of articles on quantum programming. Now for a moment we return to a more understandable - mobile development, and in a series of several articles we'll talk about the designer for developing mobile applications for online stores. This is the second attempt of the guys to create such a designer and now it is successful. Charge your experience under the cut!
 
 
Experience in creating a mobile application: it was not the first time
 
 
I give the floor to the author.

SAS BASE procedures with direct control of the number of processor cores

Some SAS procedures have the ability to directly control the number of processor cores.
 
 
For example, in SAS 9.3 these are the procedures:
 
 
SORT
 
MEANS
 
 
 
In SAS 9.? this list has significantly expanded:
 
 
MEANS
 
REPORT
 
SORT
 
SUMMARY
 
TABULATE
 
SQL
 
 
 
The number of processor cores can be set using the option. cpucount . Then, in the procedure, use the required quantity with the option directly. threads | nothreads .
 
 
Test the performance for example PROC SORT :
 
To do this, we will perform three tests:
 
 
Mono mode
 
With two cores of the processor

With the problem of "porridge" instead of readable text for decades, those who tried to open in the Windows environment text documents prepared on other operating systems. Now everything changes all of a sudden. And this change is as little, as epic, in its practical results and ideological consequences. Microsoft is again trying to play in cross-integration and support for open standards.
 
 
For many years, Windows Notepad could normally display only those text documents that contained ...

Specialists from the companies Abuse.ch, BrillantIT and Proofpoint, dealing with corporate information security, managed to implement synchronization (redirection of traffic to the front-end web server) of the management infrastructure of the EITest network and neutralize it.  About how EITest arose, and how it was managed to "cover up", we'll tell you about the cut.     /Flickr / Christiaan Colen / CC    A bit about EITest  Botnet EITest was considered "The king of ...

Understanding the life cycle of the React component

Understanding the life cycle of the React componentReact provides developers with many methods and hooks that are called during the life cycle of the component, they allow us to update the UI and the state of the application. When it is necessary to use each of them, what to do and in what methods, and what is better to refuse, is the key to understanding how to work with React.
 
by reference .
 
Although some methods are declared obsolete, their description, in my opinion, will still be useful, even for those developers who work with previous versions of React and in general for understanding instead of what methods and for which new ones ...
