Embedded Software Technology


Embedded software is very important economically because, almost each electronic device now includes software. There are many more embedded software systems than other types of software system. If you look around your house, there have one or two laptops or personal computers.

But you probably have 20 or 30 embedded systems, such as systems in phones, cookers, microwaves, etc. 

Embedded systems generally run continuously and do not terminate. They start when the hardware is switched on and must execute until the hardware is switched off. Embedded systems can be thought of as reactive systems; that is, they must react to events in their environment at the speed of that environment (Berry, 1989; Lee, 2002).

 


Technical Content Writer


Technical Content Writers are using the interactive technologies of the Web to blend text, graphics, multidimensional images, sound, and video. Technical contents writers prepare instruction as well as supporting documents for communicates complex and technical software information more easily.

Technical writers typically working with technical staff to make products easier to use and thus need fewer instructions. They also working for the standardize content across platforms and media. Technical writers create operating instructions, how-to manuals, assembly instructions, and “frequently asked questions” pages to help technical support staff, consumers, and other users within a company or an industry. Technical writers may conduct research on their topics through personal observation, library and Internet research, and discussions with technical specialists.

Technical writers must be able to understand and then explain highly technical information. Many technical writers need a background in engineering or computer science in order to do this.


Softwarization :: Telecommunication System 5G Technology


MTQ1MDc5

Softwarization brings new challenges, or at least complexities.

Software-defined networks (SDNs), network function virtualization (NFV), and cloud computing are part of the “softwarization” trend. Softwarization is expected to impact all stages of network development.

SDNs decouple hardware from software and execute the software in the cloud or in clusters of distributed IT servers. NFV applies CPU virtualization and other cloud-computing technologies to migrate network functions from dedicated hardware to virtual machines.

5G will transform the industry because the technology is expected to be able to handle much more mobile data—1,000 times the current wireless capacity, in fact. Also predicted with 5G are data rates up to 100 times higher, as many as 100 times more connected devices, and 10 times greater battery life for some of those devices.

What will differentiate 5G networks. 5G Networks will be “the ability to address varying degrees of requirements” in delay, throughput, and the types and quality of devices. 5G will require a complete revamping of the end-to-end architecture, and rethinking interfaces as well as management and control frameworks. For deployments of 5G telecommunications systems to occur in 2020, most of the research and innovation needs to be conducted soon so that large trials and testing can be completed in time.

OPEN-SOURCE SOFTWARE

There are many benefits of open-source software, the authors say. Operators and vendors can agree on requirements, for example, and quickly develop prototypes. Experimenting with open-source software such as KVM, Linux, Open Daylight, and OpenStack lowers the barrier for those who want to build a telecom network. Open-source is the easiest and fastest way to fuel innovation, according to the report. With 5G networks, the authors expect open-source code to be tested with virtual machines and enhanced on the fly.

SECURITY

Many of the security functions required for full softwarization are complex. Seemingly minor mistakes in implementation could have far-reaching impact. Operators planning to deploy open-source software have the opportunity and responsibility to ensure that due diligence has been performed, particularly when the software supports core security functions.

THE FUTURE OF TELECOM

It seems likely that traditional telecom services—as a separate industry sector—are going to disappear, the authors say. Traditional services will be packaged with others “such as voice with Internet access and premium TV” channels, they predict. There also is likely to be some merging among suppliers of traditional telecom equipment and IT hardware.

Because many service providers are global, they will begin expanding, the paper predicts. The cost of entering a new country is relatively low, assuming the infrastructure is in place, and SDNs and NFV will further lower the costs, the authors say. Softwarization is making it possible to be present in an area without any physical infrastructure at all.

“Technology is going to become accessible to all enterprises in any part of the world on an equal basis, further reducing any competitive advantage due to location,” the authors say. “Hence, the real differentiator will be the capacity to innovate continuously.”

Database Interface Design ||


UIUI Design – User Interface Design and Database Interface Design is another important skull for the organization. for the database design, a software engineer must should use Brainstorming Idea, Knowledge Base User Interactive Design, that people doesn’t feel complexity to use that database. In the last second (2nd) week of the August 2015, Al-hamdu-lillaah, I got an opportunity from a Canadian reputed organization for doing User Interface Design, Database Interface Design, beside Automation System design and rest Analysis Application Software. cover-letter

Really, an infinite opportunity came into my life to do working with a multi level international organization.

For my last 9 years competitive experiences, I like to say that become a Good User Interface UI and UX designer, always doing hard struggle and reading books, surfing design place of the web, attending conferences; formally educating self think, read lots of tutorials, watch different design, and experimenting with self idea. But, above all these are not so easy to maintain.

Quick tips

  • Design every day, when get available time. There is nothing that improves design skills at designing. So design, every day. Design at work. Go home and find little design problems in your everyday life and solve them. Have fun with it and experiment. Trial and error is a great way to learn.
  • Collect Good Design. I found that collecting screenshots for UI-Patterns.com made me a better designer. It gave me an eye for what good design is and what it looks and feels like. Always be on the hunt for spotting clever details and great design, and you will start using them yourself.
  • Test, test, test. The Heuristics will take you far, but the only true way you will learn what works and what doesn’t is through testing.
  • Iterate in increments. Deliver value in increments in an iterative fashion. Having an agile/swift process ensures you will build the right product rather than doing it right from the beginning.

Start self learning by your idea, and collect a list of various resources that will help you on your way to becoming a good designer. 


CS+X :: New Computer Science Subject


CS+X the joint-major program  that will enable students to study English and computer science, or music and computer science. CS+X, as the joint major program is called, said it will likely attract humanists who want a competitive edge on the job market; computer science-minded students who want to be engaged in the humanities; and third group of students: digital natives for whom computer science and the humanities don’t seem “at opposite ends of the spectrum at all, but continuous.”

And because technology firms often say they prefer candidates with grounding in the humanities, the joint majors may benefit even the most computer science-minded graduates on the job market.

The programs will be rigorous. Jennifer Widom, chair of Stanford’s computer science department said – ” it’s not “half of a [computer science] major and half of an English major.” It’s more like “90 percent of one and 90 percent of the other,” she said. Students majoring in the new joint programs will have to take two fewer courses in computer science than straight computer science majors, and about the same in English or music.

Music and computer science already have some cross-listed courses. English and computer science have none, but that could change over time, Jenkins said. In their senior year, joint majors in both programs will complete a capstone project integrating their two disciplines.

CS+X initially was developed by the computer science department. But last month, the Faculty Senate approved a six-year, joint-program initiative that allows for joint majors even in programs other than computer science. That initiative is inspired in part by the 2012 Study of Undergraduate Education at Stanford, which emphasized the university’s “determination to breach the silos of students’ lives.”

That means other hybrid programs could be developed going forward. English and computer science and music and computer science were the first to ask the Senate for approval.

Code of Ethics | Software Engineer


Like other engineering disciplines, software engineering is carried out within a social and legal framework that limits the freedom of people working in that area. As a software engineer, you must accept that your job involves wider responsibilities than simply the application of technical skills. You must also behave in an ethical and morally responsible way if you are to be respected as a professional engineer.

Code of Ethics – Preamble

  • The short version of the code summarizes aspirations at a high level of the abstraction; the clauses that are included in the full version give examples and details of how these aspirations change the way we act as software engineering professionals. Without the aspirations, the details can become legalistic and tedious; without the details, the aspirations can become high sounding but empty; together, the aspirations and the details form a cohesive code.
  • Software engineers shall commit themselves to making the analysis, specification, design, development, testing and maintenance of software a beneficial and respected profession. In accordance with their commitment to the health, safety and welfare of the public, software engineers shall adhere to the following Eight Principles:

PUBLIC

Software engineers shall act consistently with the public interest. Software engineers shall act in a manner that is in the best interests of their client and employer consistent with the public interest.

● Software engineers shall ensure that their products and related modifications meet the highest professional standards possible.


Thread & MultiThread


Thread (computing)

In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by an operating system scheduler. The scheduler itself is a light-weight process. The implementation of threads and processes differs from one operating system to another, but in most cases, a thread is contained inside a process. In particular, the threads of a process share the latter’s instructions (its code) and its context (the values that its variables reference at any given moment).

To arrive at a solution, software architects began writing operating systems that supported running pieces of programs, called threads. Threads are small tasks that can run independently. Each thread gets its own time slice, so each thread represents one basic unit of processor utilization. Threads are organized into processes, which are composed of one or more threads. All threads in a process share access to the process resources.

Another Way, In Programming Language

public class Thread
extends Object
implements Runnable

A thread is a thread of execution in a program. The Java Virtual Machine allows an application to have multiple threads of execution running concurrently.

Every thread has a priority. Threads with higher priority are executed in preference to threads with lower priority. Each thread may or may not also be marked as a daemon. When code running in some thread creates a new Thread object, the new thread has its priority initially set equal to the priority of the creating thread, and is a daemon thread if and only if the creating thread is a daemon.

When a Java Virtual Machine starts up, there is usually a single non-daemon thread (which typically calls the method named  main of some designated class). The Java Virtual Machine continues to execute threads until either of the following occurs:

  • The exit method of class Runtime has been  called and the security manager has permitted the exit operation to take place.
  • All threads that are not daemon threads have died, either by  returning from the call to the run method or by  throwing an exception that propagates beyond the run  method.

There are two ways to create a new thread of execution. One is to declare a class to be a subclass of Thread. This subclass should override the run method of class  Thread. An instance of the subclass can then be allocated and started. For example, a thread that computes primes larger than a stated value could be written as follows:


     class PrimeThread extends Thread {
         long minPrime;
         PrimeThread(long minPrime) {
             this.minPrime = minPrime;
         }

         public void run() {
             // compute primes larger than minPrime
              . . .
         }
     }

The following code would then create a thread and start it running:

     PrimeThread p = new PrimeThread(143);
     p.start();

Multiple threads can exist within the same process and share resources such as memory, while different processes do not share these resources.
