JavaScript inherently has Single threaded Synchronous Execution i.e. javascript is running on a single thread, line by line, in the sequence in which code is written. But then the big question is how can it handle all the Events like Clicks or Hover and many other like. Even bigger question how AJAX works in JavaScript? … More Pesudo Asynchronous JavaScript
While working on a sample problem, I got stuck in a problem (Eventually solved) due to some misplacement of parameters in the function (Which is not much important ) and I got the error message stating “Root segment cannot have matrix parameters” Which was like why root URL can’t have parameters with the mindset that … More Matrix URI
Shared_pointers #include<iostream> int main(){ int *b=new int(12); //initialize the pointer int *c; c=b; //make pointer c points to same pointer delete b; //delete the pointers std::cout<<*c; } Above program will produce an error on running. Why? because the object to which c was pointing got deleted will c is still pointing to it. In … More Grown Up Pointers
Declarations is specifying the properties of an identifier. In c++, the declaration have five parts: • Optional prefix specifiers like static, extern etc • A base type like int, char, const float etc • A declarator like p[7] , n etc • Optional suffix function specifiers like const, noexcept etc • An optional initializer or … More The Structure of Declarations
So, Here is the normal swap that we write which is inefficient as it makes a lot of copies. swap(T& a, T& b) { T tmp {a}; a = b; b = tmp; } So, what happens is that first value of “a” is copied inside “tmp”, then value of “b” is copied into “a” … More Efficent way to swap
Cache are basically fast memory but small in size. Cache is close to CPU and every data that have to be processed is first fetched from memory to cache and then send to registers in CPU for processing but How data is stored or mapped from memory to cache? It can be done in following … More Cache Associativity
This will be the finale of the trilogy of posts describing my GSoC project User Interface for Customizing Models. In last two posts, I described the main features of OpenSCAD customizer. In this post we will start with how the customizer will be integrated in OpenSCAD initially and how will you be able to use … More User Interface for Customizing Models ( Part 3)
In the last blog, we left at How to parameterize the variables. Now next thing is to group the parameters so that it become easy to manage those parameters.Parameters can be grouped into tabs. This feature will allow us to separate similar and related parameters. The syntax for this is also mainly similar to that … More User Interface for Customizing Models ( Part 2)
