A web camera is absolutely necessary when connecting with friends via video call software like Skype or Google hangouts. But when the built-in webcam is your laptop has stopped working, what would you do? Send it to computer repair store or buy a new external computer camera? Actually the repair cost may be higher than a new external camera. And If you require high quality video call, it’s better to have a USB camera. You have many choices of a good desktop webcam. What you should do to change built-in webcam to external computer camera?

Disable Internal Webcam
Disable the internal webcam through Windows. Click in the top right-hand corner of Windows and select the "Search" charm, then type "device manager." Click on "Device Manager" under "Control Panel" to launch Device Manager. Expand the section beside "Imaging Devices" and then right-click on your webcam and choose “Disable”. After these process, your computer program like Skype is able to recognize your new pc camera.

Apple makes fantastic mobile products, but its flimsy USB lightning cable deteriorates too quickly. One of the most common problems faced by iPhone and iPad owners is a frayed Lightning connector. Surely there must be tougher, more rugged options?

The obvious solution is to go back to the Apple store and claim the warranty (or AppleCare if you have it). Another options is to ditch Apple's cable altogether and get something better made by a third party.

We can say that mobile and tablet applications have replaced the TV because in the research, it is found that people today spend minimum three hours every day on their mobile devices. Android development India team experts are leaving no room for bugs in such applications that could disturb the audience while watching their shows. More entertainment applications are coming with their own web series and movies and thus, people spend lesser time on TV nowadays.

The days are gone when we called television the “first screen” for entertainment. Lots of entertaining applications are now made by android developers and the idiot box has been replaced by phones and tablets officially as the trend is on rise for the past two years.

querydsl

Technology: Querydsl is a java based framework which enables the construction of statically typed SQL-like queries. Instead of writing queries as inline strings or externalizing them into XML files they can be constructed via a fluent API like Querydsl.we can use Querydsl in java application for creating all kinds of sql statements.Querydsl has various plugins for JPA,mongoDb, SQL,lucene and also for java collections.

Asp.net MVC developers working with MNC’s have in-depth experience in developing MVC application. In this post, they will explain how to create a sample app with asp.net 5, which will store the data in Azure SQL. They are using Entity Framework and Scaffolding of asp.net MVC in the sample. For more information, read blog further.

In this post we will create a sample application using ASP.NET 5. That application will store the data in the Azure SQL using Entity Framework and Scaffolding of asp.net MVC to support the basic operations (CRUD).

The development team working on PVS-Studio has finally started developing its product for Linux. That was the news that the CTO Andrey Karpov wrote about in the article. Long disputes and requests of the readers on habrahabr.ru, discussions on Reddit, Linux.org and other places can now gain a new round of comments. As it is mentioned in the article, you can volunteer to help the developers to test this product and improve it to a better level.

There are many tasks on the way of PVS-Studio to Linux, that the technical director is talking about. Put briefly, these are:

- more complete support of GCC and Clang;
- a new system of regression tests in Linux, so that you can track the changes results in the analyzer kernel and add new diagnostics;
- compiler monitoring to help programmers quickly and easily check the project without distracting people who support makefiles and the build system in general;
- documentation improvement, so that the user can get information with the examples about any diagnostic;
- testing, distribution, support organization.

In this article you will find more details about the abilities of PVS-Studio for Windows and the tasks it can already solve on Linux.

Often people ask questions - which programming language is easier, which is the most popular, which one to start learning and so on. In this article we will compare two languages Python and Ruby; their reference implementations CPython and MRI, to be exact.

We took the latest versions of the source code from the repositories (Ruby, Python) for the analysis. There weren’t many glaring errors in these projects. Most of them are related to the usage of macros, although this code is quite innocent from the point of view of the developer. But at the same time, such suspicious fragments that occurred because of copy paste, comparing SOCKET type with null, undefined behavior, storing values to the variables that are already used or null pointer dereferencing are really worth reviewing.

Having analyzed all the warnings of general analysis diagnostics and removed all the false positives, we have come to the following conclusion concerning the error density:

More details about the code fragments where these suspicious code fragments were found:

It’s worth saying that despite these flaws, the code is still of high quality. We should also take such factors into account as the size of the codebase , or the fact that some fragments are erroneous only from the point of view of C++ language and they don’t affect the program in any way. That’s why this analysis may be rather subjective, because previously we haven’t evaluated the error density of these projects. We’ll try to do that in the future, so that we can later compare the result of the checks.

Nowadays a lot of projects are opening their source code and letting those who are interested in the development of it edit the code. OpenJDK is no exception, programmers PVS-Studio have found a lot of interesting errors that are worth paying attention to.

OpenJDK (Open Java Development Kit) - a project for the creation and implementation of Java (Java SE) platform, which is now free and open source. The project was started in 2006, by the Sun company. The project uses multiple languages- C, C++, and Java. We are interested in the source code written in C and C++. Let's take the 9th version of OpenJDK. The code of this implementation of Java platform is available at the Mercurial repository.

During verification, the analyzer found different errors in the project including: copy-paste, bugs in the operation precedence, errors in logical expressions and in pointer handling and other bugs, which are described in detail in this article.

It's always amusing to check a project which is used and maintained by a large number of people. The better and more accurate the code is, the more safely and effectively the program will work. Those bugs we found, are another proof of the usefulness of an analyzer, as it allows the detection of such errors which would otherwise be hard to detect doing simple code review.

Here is a small e-Book for your attention: The Ultimate Question of Programming, Refactoring, and Everything. This book is intended for C/C++ programmers, but it could be of interest for developers using other languages as well.

What makes the book peculiar is the descriptions of real, not theoretical cases at the base of it. Each chapter starts with a code fragment taken from a real application, and then the author gives various tips of how this bug could be avoided. The questions touched upon in this book can help the readers improve the personal coding style and the coding standards used in the team.
