Webcom Technologies: iOS Application Debugging

Webcom Technologies proposes tutorial to debug application in iOS. As per webcom technologies,When we do application we may commit mistakes which can lead to different kinds of errors. So in order to fix these errors or bugs we need to debug the application.

Selecting a Debugger

Xcode has to debuggers namely GDB and LLDB debuggers, and GDB is selected by default. LLDB is a debugger that is part of the LLVM open source compiler project. You can change the debugger by edit active schemes option.

How to find coding mistakes?

We just need to build our application and our code is compiled by compiler and all the messages, errors and warnings with their reason will be displayed and we can correct them. .

Set Breakpoints

Webcom technologies explains :Break points help us to know the different states of our application objects which help us identifying many flaws including logical issues. We just need to click over the line number to create a breakpoint. We can click and drag it out to remove the break point. An example breakpoint is shown below.

When we run the application and select the playVideo button the application will be paused for us to analyze the states of our application. When breakpoint is triggered we will get an output as shown below.

You can easily identify which thread has triggered the breakpoint. In the bottom you can see objects like self, sender and so on which hold the values of corresponding objects and we can expand some of these objects and see what is the state of each of them.

To continue the application we will select the continue button (left most button) in the debug area shown below. The other options include step in, step out and step over.

Exception breakpoint

As per Webcom technologies lesson,We also have exception breakpoint that triggers application to stop in location where the exception occurs. We can create exception breakpoint by selecting the + button after selecting the debug navigator. You will get the following window.

Then we need to select Add Exception Breakpoint which will show the following window.

Webcom Technologies:Hadoop Training

Webcom Technologies proposes a new course: Hadoop. Hadoop is a type of software designed to organise and process the clusters of complex data. Through a single server, thousands of machines can be used for storage. Big Data Hadoop is the latest trend in the information technology world. Every time when you like a status in Facebook, comment on someone’s photo, tweet about something upload a video etc., do you realize that you are adding to the bundles of big data? It seem, 90% of the world’s data today is created within the span of just 2 years and Big Data is growing bigger and bigger every day. Big data is the collection of large and complex sets of data and files. These large collections of complex data cannot be organized or managed by regular tools and therefore, there is Hadoop.

Following are the courses and its content proposed by Webcom Technologies.

Webcom Technologies:ERP Trends in Mobile Apps and Integrated Processes

Webcom says,selecting and implementing an ERP solution is always a key strategic decision for CIOs. However, the introduction of enterprise software is anything but trivial, and in many ways, is a mission-critical investment.

When choosing an ERP system, 88% of CIOs prefer an integrated IT system. These promise seamless and more stable business processes. Only 11% of IT directors prefer to map business processes based on a best-of-breed approach that uses multiple tailored solutions.

Key requirements for the ERP system

According to Webcom,Ideally,classic ERP core areas such as logistics, warehouse management, and accounting should be closely integrated in order to minimize costs for setting up and maintaining interfaces and data transfers between individual solutions. A key requirement for 84% of those surveyed is that scanner applications are also integrated into the overall ERP system. 72% also want integrated functions for product development and recipe management. 71% of IT directors also think it would be useful if the future ERP system contained workflow components. This would allow processes such as document forwarding, invoice processing, and approval processes to be automated.

ERP processes via tablets and smartphones

For Webcom,three quarters of IT managers believe that mobile apps for business intelligence will play an important or very important role in three years. The figure currently stands at 60%. Mobile BI apps will allow managing directors and other decision makers to retrieve business KPIs and liquidity analyses, for example, on the move, and to access the latest data about company development.

As far as Webom is concerned,within the course of normal ERP operations, IT outsourcing services are often used. 29% of respondents said that they had outsourced system monitoring to an external service provider, and slightly more than a quarter said they had outsourced the hosting of an ERP application as a managed service. By 2016, a further 28% intend to outsource system monitoring to an external IT provider, and one quarter also intend to outsource hosting services. .

Webcom Technologies: Choose a Real-Time Operating System

Webcom Technologies  provides article on c RTOS to choose a Real-time operating system? This article provides an overview of RTOSes and how you can select the best one for your project.

Engineers often use the term “real time” to describe computing problems for which a late answer is as bad as a wrong one. These problems are said to have deadlines, and embedded systems frequently operate under such constraints. Webcom Technologies renders a brief introduction with Real Time System:

Real time systems

The designers of real-time systems at webcom technologies spend a large portion of their time worrying about worst-case performance. They must constantly ask themselves questions like: what is the worst-case time between the human operator pressing the brake pedal and an interrupt signal arriving at the processor? What is the worst-case interrupt latency?

Most of the commercial embedded operating systems available today are designed for possible inclusion in real-time systems. In the ideal case, their worst-case performance is well understood and documented. To earn the distinctive title “Real-Time Operating System” (RTOS), an operating system should be deterministic and have guaranteed worst-case interrupt latency and context-switch times. Given these characteristics and the relative priorities of the tasks and interrupts in your system, it is possible to analyze the worst-case performance of the software using a technique such as rate monotonic analysis.

Webcom Technologies finds three major parameters of choosing the OS. An operating system is said to be deterministic if the worst-case execution time of each of its system calls is calculable. An operating system vendor that takes the real-time behavior of its product seriously will usually publish a datasheet providing the minimum, average, and maximum number of clock cycles required by each system call.

Interrupt latency is the total length of time from an interrupt signal arriving at the processor to the start of the associated interrupt service routine (ISR). When an interrupt occurs, the processor must take several steps before executing the ISR. First, the processor must finish executing the current instruction. Next, the interrupt type must be recognized. This is done by the hardware and does not slow or suspend the running task. Finally, and only if interrupts are enabled, the CPU’s context is saved and the ISR associated with the interrupt is started.

The third real-time characteristic of an operating system is the amount of time required to perform a context switch. This is important because it represents overhead across your entire system. For example, imagine if the average execution time of any task before it blocks is 100ms but that the context-switch time is also 100ms. In that case, fully one half of the processor’s time is spent within the context-switch routine!

Again, there is no magic number and the actual times are usually processor-specific, since they are dependent on the number of registers that must be saved and where. Be sure to get these numbers from any operating system vendor you are thinking of using. That way, there won’t be any last minute surprises.
