React applications are essentially HTML, CSS and plain javascript after they get built for production. These files can run on any kind of server. In fact they can be run right from your file system, like any simple HTML page
Today, the 20th Feb, 2019 I am going to undertake my biggest challenge till date. I am going to commit a little bit of my time everyday towards learning/mastering the React library, which is a frontend javascript library.
Javascript, being a high level language does not have pointers, unlike C or C++. One cannot get the value of the memory address where a javascript variable is stored. But the concept of pointers (references) is unavoidable in any programming language.
If you have been working on wordpress websites for personal or professional reasons, lately you might have become frustrated with the new wordpress update to version 5.x and the sole reason is Gutenberg sucks!!! But don’t lose faith in the wordpress eco-system yet. The wordpress community is still supporting the old classic editor that we all love. Let me tell you how to get back Classic Editor in Wordpress 5.
A few days ago I saw a video on SmarterEveryday, a youtube channel which makes science related videos. That video illustrates how we can understand Fourier Series with the help of animations of sinusoidal waves. The original creator made the animations using a different software/language. But I thought I can make it in javascript and run it on a browser, and host it in my website.
Today we are going to discuss FILE SYSTEM operations using the C language. Till now we have worked with the RAM for storing our variables and our data. But the RAM is not persistent. We need to store data permanently. So we store them in permanent memory like hard disks or CDs/DVDs, in files. Different types of data are stored in different type of files, but for our purposes we’ll work with text files in windows system which have an extension of ‘.txt‘.
Today we’re going to discuss two topics which are rarely taught in a C programming college course, Unions & Enums. One may justify that by saying they are not absolutely necessary for basic knowledge in programming, or that these topics are rarely asked in interviews. But if you become a professional C developer, you’ll have extensive use of them. These are particularly useful in low level programming, like with embedded systems and robotics.
One of the main motivations in the development of computers was data processing. One of the earliest punched card machines (tabulation machine) were used to help process data for the 1890 U.S. Census. Thus in programming languages data types were so important, as there are tools and methods to process data according to their type.
The process of allocating memory while a program is running is called dynamic memory allocation. In C programming, dynamic memory allocation is achieved with the standard library functions malloc(), calloc(), realloc() and free().
To proceed to the next sections in our discussion on C programming language, we should learn the concept of void pointers, i.e. pointers of no specific type, and type casting, i.e. manually changing the data type of a variable. Type conversion can happen automatically (implicitly) or manually (explicitly). The later is termed as type-casting.
