   • Central Processing Unit (CPU)

     The full form of CPU is Central Processing Unit . It is a brain of the computer. All types of data processing operations and all the important functions of a computer are performed by the CPU. It helps input and output devices to communicate with each other and perform their respective operations. It also stores data which is input, intermediate results in between processing, and instructions. 

     What is a CPU?

     A Central Processing Unit is the most important component of a computer system. A CPU is a hardware that performs data input/output, processing and storage functions for a computer system. A CPU can be installed into a CPU socket. These sockets are generally located on the motherboard. CPU can perform various data processing operations. CPU can store data, instructions, programs, and intermediate results.

     History of CPU

     Since 1823, when Baron Jons Jakob Berzelius discovered silicon, which is still the primary component used in the manufacture of CPUs today, the history of the CPU has experienced numerous significant turning points. The first transistor was created by John Bardeen, Walter Brattain, and William Shockley in December 1947. in 1958,...

   • Unit testing code that does date processing based on today's date

     Top Answer

     Answered Feb 19, 2009 · 21 votes

     In our code we always pull out the current date using DateTime.Now (.NET, in our case). How can you unit test such code?

     This is a dependency, and a non-deterministic dependency at that. You need to divide the responsibility of the code up a little more.

     Before:

     • There is some code that uses the current datetime to do X.

     After:

     • There should be some code that is responsible for getting the current datetime.
     • There should be some code that uses a datetime to do X.

     These two sets of code should not be dependent on each other.

     This pattern of seperating dependencies works for other cases as well (database, filesystem, etc).

     Using DI for injecting "Current Date & Time" is surely an overkill. I'd rather refactor the code to operate on arbitrary date. That is, I'd change function calculateRevenue() to function calculateRevenueOn(datetime date). This is much easier to test and use in case you need calculation for some dates other than current.

     Always put the core date processing logic (which is, in my experience, usually easy to isolate for this purpose) into separate methods that take the date as a parameter.

     Then, in your production code you can call those and give them the current date as parameter, and still test edge cases to your heart's content in unit tests.

     BTW, I've found it quite crucial to test date logic very intensively for edge cases. It eliminates (possibly catastrophic, ref. Zune) bugs that you'd never have found otherwise. Apart from the ones you mentioned, daylight savings time switches can also be problematic.

   • Central Authentication Service

     Central Authentication Service is a single sign-on protocol that is developed to permit a user to have access to multiple applications using the same underlying authentication service. The main thing about this is authentication process can only happen on the CAS server which means applications that authenticate with CAS never see the user’s credentials. CAS also permits various applications to authenticate users in the absence of gaining access to a user’s security credentials. CAS process has three main parties namely a client web browser, the web application requesting authentication, and the CAS server other than that it might have database server which provides backend service and also communicates with the web application.

     Working of Central Authentication Service:One’s the client visits a web application seeking authentication, the web application automatically redirects it to CAS and then by checking credentials like username and password against a database CAS validates the authenticity of the client, then after the whole process if the authentication process gets successful CAS returns the client to the application with a security ticket. Then the ticket gets validated by the web application by contacting CAS which...

   • Central difference with Convolution

     Top Answer

     Answered Apr 28, 2020 · 2 votes

     We can simply slice and operate. Hence, after output initialization, do -

     result[1:-1,1:-1] = (arr[2:,1:-1] - arr[:-2,1:-1])/(2*dx)-

     Convolution IMHO would be an overkill when working with NumPy arrays, as slicing arrays are virtually free on memory and performance. Being compute heavy, one can look into numexpr though to leverage multi-cores.
