   • How Programming Languages are Changing the World?

     Programming has been revolutionizing the world since the advent of the first software or a code-based project. Programming or coding has opened numerous new ways and paved the way for innovation in almost every industry. Today, with various types of coding languages available and modern tech-powered tools to assist, something new and innovative is always around the corner.  

     Moreover, programming is one of the most demanded skills today when it comes to recruitments in not only the IT and software field but also in non-tech organizations. Almost everything that you run or browse on your smartphone or laptop is powered by some coding language. In real-life instances and scenarios as well, coding languages have entirely revolutionized the way people live and perform specific tasks.

     That’s the reason Barack Obama has started the Computer Science for All initiative in the US to bring coding and programming to the curriculum of the students right from early schooling.  Let us briefly understand how coding languages have changed the world for the better and are still doing it.

   • Are polling and event-driven programming different words for the same technique?

     Top Answer

     Answered Nov 26, 2012 · 17 votes

     Nope, quite the contrary interrupt driven programming is pretty much what event driven programming is at the hardware level. Both interrupt driven code and event driven code waits for event before running a code, while polling will attempt to query for event whether or not one actually exists.

     However, it should be noted that interrupt- and event-driven programs are generally implemented in the lower level using a form of polling; there is no truly interrupt or event driven system that does not involve some sort of polling, although usually in hardware. In the case of interrupts, the CPU actually polls the interrupt line every clock cycle, and likewise with event driven programming because restarting a paused thread involves an interrupt being raised by the source of event (usually drivers).

     You can say that interrupt- and event- driven programming is a disciplined way to poll that have lots of advantage compared to actually doing polling yourself.

   • Are "data races" and "race condition" actually the same thing in context of concurrent programming

     Top Answer

     Answered Oct 16, 2014 · 201 votes

     No, they are not the same thing. They are not a subset of one another. They are also neither the necessary, nor the sufficient condition for one another.

     The definition of a data race is pretty clear, and therefore, its discovery can be automated. A data race occurs when 2 instructions from different threads access the same memory location, at least one of these accesses is a write and there is no synchronization that is mandating any particular order among these accesses.

     A race condition is a semantic error. It is a flaw that occurs in the timing or the ordering of events that leads to erroneous program behavior. Many race conditions can be caused by data races, but this is not necessary.

     Consider the following simple example where x is a shared variable:

     Thread 1 Thread 2- lock(l) lock(l) x=1 x=2 unlock(l) unlock(l)-

     In this example, the writes to x from thread 1 and 2 are protected by locks, therefore they are always happening in some order enforced by the order with which the locks are acquired at runtime. That is, the writes' atomicity cannot be broken; there is always a happens before relationship between the two writes in any execution. We just cannot know which write happens before the other a priori.

     There is no fixed ordering between the writes, because locks cannot provide this. If the programs' correctness is compromised, say when the write to x by thread 2 is followed by the write to x in thread 1, we say there is a race condition, although technically there is no data race.

     It is far more useful to detect race conditions than data races; however this is also very difficult to achieve.

     Constructing the reverse example is also trivial. This blog post also explains the difference very well, with a simple bank transaction example.

   • Are those two regular languages the same?

     Top Answer

     Answered May 23, 2017 · 1 votes

     No, because both languages are different so you can't draw single DFA for both languages.

     An automaton uniquely defined a language, but yes of-course for a language more than one automata are possible called 'equivalent automata'.

     Language L1 = A = {xy | Na(x) = Nb(y)} is a regular language. Regular expression for this language is:

     (a + b)*a(a + b)*b(a + b)* + ^

     To understand this language and regular expression read: "Show that the following set over {a, b}

     is regular".

     Language L2 = A = {w | Na(w) and Nb(w) are even number} is also a regular language. Regular expression for this language is:

     ((a + b(aa)*ab)(bb)*(ba(aa)*ab(bb)*)*a + (b + a(bb)*ba)(aa)*(ab(bb)*ba(aa)*)*b)*

     To understand this language and regular expression read: "Need Regular Expression for Finite Automata".

     But both languages are not equal because there are some strings in language L1 those are not belongs to language L2 e.g. ab is a string in L1 but doesn't not consist of even number of a and b hence doesn't belongs to language L2.

     Note: Language L2 is either not a subset of language L1, because in L2 a strings of even length and single symbol is possible like aa, aaaa, bb, bbbb but these strings are not member in L1.

     Both languages are different hence single DFA is not possible for both languages.

   • How do qubits work and what are their pros and cons? What impact will they have on programming languages?

     Top Answer

     Answered Aug 03, 2010 · 5 votes

     Any "classical" (as it will be called once the technology is in wider use) problem which is solved by "classical" code can be solved using some sort of quantum processor by transforming the problem. For example, to do a database search, instead of using an index-based search/binary search, or a linear search for an unsorted database, you can use Grover's algorithm. Also, to take a step back from the previous poster's mention of BQP problems, problems with a classical "solution" that runs in NP-time can be sped up considerably by Grover's algorithm (a speedup in the time to search through every possible solution). RSA cryptography is also made much more insecure by the advent of Shor's algorithm, since it makes factorising large numbers into their prime factors (the hinge upon which RSA sits) solvable in logarithmic time.

     EDIT: Shor's algorithm actually runs in O((log N)^3), which is polynomial-over-logarithmic time.

     The conclusion of this sort of thing is that pre-existing programming languages like C will not be able to be used on a quantum computer due to the nature of quantum algorithms (applying certain functions to quantum states), unless someone invents a way to map quantum gates and so forth to logical gates (EDIT: This has apparantly been mostly addressed here), in which case about all we get is a very very fast logical processor when using languages like C.

     PS: I'm sure there'll be OpenGL bindings for quantum computing eventually :P

   What is the difference between programming language and protocol?

   • in my opinion. programming language doesnt do anyting until implemnted in machine code. so language and protocol are both rules in different pardigms. The distinction is a matter of degree. Consider the security procedures at a major bank.

   Is a protocol a language?

   • A protocol also defines the format of messages, which is a language, though it's not commonly called that. For example, you can't really say that GET /index.html HTTP/1.0 is a valid string in the protocol HTTP, even though it's a valid HTTP client request.

   Having multiple languages in one project is actually quite common, however the principles behind are not always simple. In the simple case, different languages are compiled to the same code. For example, C and C++ code typically is compiled into machine assembler or C# and VB.Net is compiled into IL (the language understood by the .NET runtime).

   Usage example

   static void Hello(){ Console.WriteLine("Hello World");}
