Password Manager Apps ease your life but not all of them are highly reliable

Password Manager Apps ease your life but not all of them are highly reliable.

With a Password Manager, user can easily manage your entire password affair without even remembering them every now and then. There are countless password managers out in the web world, which ease to your life but not all of them are highly reliable.

Dashline is a free to use password manager that combines extension and interface to create a fluid user experience. The only downside of using Dashline probably is you need to manually sync the devices.

LastPass is a legend in the arena of password management. From laptops to smartwatches, LastPass allows passwords to be saved and accessed from any device.

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).

Registry File Cannot Clean, USE iobit Uninstaller

Uninstall Root FileSometimes, when uninstall the software or application (apps), then user thought that all root files and unnecessary file has been removed of that uninstall software. But, exactly windows cannot perform that job as well as unable to remove the root file of that software. So, in future, PC, Laptop should be decreased performance and infected with malware by using those root files of the uninstall software.

So, PC users must use some technique for removing these root files of the unnecessary software or uninstalling software’s.

Try to use iobit Uninstaller or IObit Advanced System Care; it’s a clean and perfect tool for desktop and laptop, Smartphone, and Tab.. When you should be uninstall any software by windows default mode, then automatically iobit uninstaller will give to suggest and warning that remove registry file of the Uninstall Software.

Adobe AIR and Why should be Install This

People can think and moreover ask me that why install Adobe AIR. Exactly, Adobe AIR is a part as well as Cross-OperatingSystem. 

Adobe AIR runs on all Windows®, Mac OS, Android™, iOS, and BlackBerry® Tablet OS.

Adobe AIR is a Cross-OperatingSystem runtime that lets developers combine HTML, JavaScript, Adobe Flash® and Flex technologies, and ActionScript® to deploy Rich Internet Applications (RIAs) on a broad range of devices including desktop computers, netbooks, tablets, smartphones, and TVs. AIR allows developers to use familiar tools such as Adobe Dreamweaver®, Flash Builder®, Flash Catalyst®, Flash Professional, or any text editor to build their applications and easily deliver a single application installer that works across operating systems -OS.adobe-air-8

AIR has a Security Model That Is More Like Desktop Applications…  Since AIR applications are persistent — installed on a user’s machine — AIR has a security model that is more like desktop applications. The browser sandbox provides a restricted environment for running web applications that can come from various sources, including anonymous or untrusted websites. AIR, like other desktop runtimes, provides applications with access to powerful capabilities, such as local file access, that should be provided only to trusted applications. AIR improves on the security model of most desktop runtime by providing information about the security of an application before it’s installed and configured on your system.

Gaming.. Enjoy stunning, blazing-fast cinematic 2D and 3D games for desktop, iOS, and Android™. Using fully accelerated GPU rendering and game controller support for gaming at home or on the go.

High Performance.. Experience hardware accelerated HD video with smooth playback. Recent improvements allow supported AIR apps and games to deliver responsive feedback even at the most demanding times.

Adobe Flash Player is a Browser Plug-In… Adobe Flash Player is a browser plug-in that provides advantages for users and content creators in the browser, including the ability to deliver RIAs in the browser. AIR incorporates technologies originally developed in Flash Player and enables RIAs on the desktop. AIR and Flash Player provide complementary deployment methods for RIAs.

Tires with Built – in Sensors Keep a Watchful Eye on Tread Wear

Continental is bolstering its Tire Pressure Monitoring System (TPMS ) to not only monitor your tire pressure but its tread depth, too. As your tires age and change shape, so does the way they roll and interact with the road surface. Continental’s clever system keeps track of these differences and compares them over time with model-specific stored data. When your tires eventually hit some pre-determined threshold, the car will notify you that your boots have reached their end of life. Continental expects this to roll into retail for the 2017 season in cars equipped with its TPMS systems. But fret not, you can always use that old standby — your eyes — to actually look and see if the tread wear indicators are flush with the tire surface. If they are, remember it’s safety first, so go get yourself a new set.

Creator Of OPERA Browser ::

Creator Of OPERA Browser :: Stephenson Von Technarey   

PC Users & Cell Phone Users are so much like the browser OPERA & OPERA Mini. But who is the creator of this latest Application Soft. He is Stephenson Von Technarey. On 1997, Stephenson & His friend Gear accordingly was create the OPERA Browser. Stephenson first was proposed that he want to create an Uncommon But special Browser, which browser can work in Computer & Cell Phone, Smart Phone. Finally, they were got success. On 2004, OPERA Browser was earned the member of Oslo Stock Exchange. When Stephenson was created this browser, then stay in Norway Telecommunication Industry – Telenor. Telenor Company was doing marketing this Browser Application. For this Success, TELENOR give him (Stephenson) to the Position – CEO. On 1998, Stephenson was doing hardly work & analysis on OPERA MINI Web application for Smart Phone & Mobile Phone, that Users can easily browse in Cell Phone & Smart Phone. But on 5th January, 2010, Unfortunately, TELENOR was remove him (Stephenson) officially from the position “ CEO ” & give him the post advisor. That time Stephenson was got so much shocked that’s why He left from TELENOR.        



Automating Software systems reminds me of teaching a kid to ride a bicycle. A hands – on phase, in which you directly control the process, segues into a hands – off phase as the kid, having internalized the skill, asserts control. During that segue, however, there is a complex negotiation. Control is traded back and forth in varying degrees, governed by a sensitive two-way feedback mechanism.

Web software is easy to automate because there’s often a one – to – one correspondence between a hands – on action — “download transactions for these dates” — and its hands – off equivalent: the scriptable URL that expresses that action. This, for me, is the supreme benefit of the Web’s REST (Representational State Transfer) model, and the reason why I consider myself to have been a user of Web services since well before the advent of SOAP. 

On the other hand, GUI Software, doesn’t naturally display this one – to – one correspondence between actions and statements that describe actions. Yet, it’s still achievable or realizable. Using the macro – recording features of Microsoft Office I can, for example, convert a hands – on action — “build up the lines for each data series in the chart” — into a hands-off equivalent: the VB code that expresses that action. 

Either way, what’s missing is the sensitive feedback. To automate a task I turn on the macro recorder, self – consciously perform the task, analyze it, fiddle around with the script and then package it for reuse. So long as the context remains the same, the script will continue to work. Of course, the context never does remain the same, and I’ll end up adjusting the data sources read by my account exporter and tweaking the charts created by my log visualizer. 

It only takes a light touch to get the kid on the bicycle to sense and react to my cues, but I have to clobber my software to make it pay attention. Getting applications and services to share a common message bus should help. Easier said than done.



In a multiprogramming environment, it is not unusual for several programs to require the same I/O device. For example, two or more programs may be competing for the printer. Rather than hold up the processing of a program by waiting for the printer to become available, both programs are execute & the printer output for one is temporarily loaded to magnetic disk. As the printer becomes available, the output is called from magnetic disk & printed. This process is Spooling.          

Software Development Life Cycle :: SDLC

Six Sigma is a methodology to manage process variations that use data and statistical analysis to measure and improve a company’s operational performance.

It works by identifying & eliminating defects in manufacturing and service-related processes. The maximum permissible defects is 3.4 per one million opportunities.

Domain Analysis ≡ Often the first step in attempting to design a new piece of software, whether it is an addition to an existing software, a new application, a new subsystem or a whole new system, is, what is generally referred to as “Domain Analysis”. Assuming that the developers (including the analysts) are not sufficiently knowledgeable in the subject area of the new software, the first task is to investigate the so-called “domain” of the software. The more knowledgeable they are about the domain already, the less work required. Another objective of this work is to make the analysts, who will later try to elicit and gather the requirements from the area experts, speak with them in the domain’s own terminology, facilitating a better understanding of what is being said by these experts. If the analyst does not use the proper terminology it is likely that they will not be taken seriously, thus this phase is an important prelude to extracting and gathering the requirements.

Software Elements Analysis ≡ The most important task in creating a software product is extracting the requirements. Customers typically have an abstract idea of what they want as an end result, but not what software should do. Incomplete, ambiguous, or even contradictory requirements are recognized by skilled and experienced software engineers at this point. Frequently demonstrating live code may help reduce the risk that the requirements are incorrect.

Scope Analysis ≡ Also known as Requirement Analysis. Once the general requirements are gleaned from the client, an analysis of the scope of the development should be determined and clearly stated. This is often called a scope document. Certain functionality may be out of scope of the project as a function of cost or as a result of unclear requirements at the start of development. If the development is done externally, this document can be considered a legal document so that if there are ever disputes, any ambiguity of what was promised to the client can be clarified.

Specification ≡ Specification is the task of precisely describing the software to be written, possibly in a rigorous way. In practice, most successful specifications are written to understand and fine-tune applications that were already well-developed, although safety-critical software systems are often carefully specified prior to application development. Specifications are most important for external interfaces that must remain stable. A good way to determine whether the specifications are sufficiently precise is to have a third party review the documents making sure that the requirements are logically sound.

Software Architecture ≡ The architecture of a software system refers to an abstract representation of that system. Architecture is concerned with making sure the software system will meet the requirements of the product, as well as ensuring that future requirements can be addressed. The architecture step also addresses interfaces between the software system and other software products, as well as the underlying hardware or the host operating system.
Implementation ≡ This is the part of the process where computer scientists actually program the code for the project.

Testing ≡ Testing software is an integral and important part of the software development process. This part of the process ensures that bugs are recognized as early as possible

Deployment  After the code is appropriately tested, it is approved for release and sold or otherwise distributed into a production environment.

Software Training and Support ≡ A large percentage of software projects fail because the developers fail to realize that it doesn’t matter how much time and planning a development team puts into creating software if nobody in an organization ends up using it. People are often resistant to change and avoid venturing into an unfamiliar area, so as a part of the deployment phase, it is very important to have training classes for new clients of your software.

Maintenance ≡ Maintaining and enhancing software to cope with newly discovered problems or new requirements can take far more time than the initial development of the software. It may be necessary to add code that does not fit the original design to correct an unforeseen problem or it may be that a customer is requesting more functionality and code can be added to accommodate their requests. It is during this phase that customer calls come in and you see whether your testing was extensive enough to uncover the problems before customers do.
