There is a negative impact in performance, because the more directives you use the slower your server becomes, especially if you have to place the code in per-directory configuration files such as .htaccess instead of the main configuration file (e.g. httpd.conf). Plus, your response headers will be a bit bigger if you send both Cache-Control and Expires headers.

HTTP/1.0 browsers have been extinct over a decade ago and there’s little chance of requests from HTTP/1.0 user agents (bots, crawlers, web server scanners etc.). Support for browsers is certainly not the case. But I’ll probably end up using Expires to cover all kinds of clients.

The pages of WordPress use PHP templates so the page extension should be .php. I just needed someone to verify that.

So I proceeded to add php in FilesMatch and it worked.
Do you know anything about my first question? (I’ve edited my post and removed the second)

The quick and dirt solution I think is through calculating the area and using a function that draw a polygon shaped button. It doesn’t seem too optimized. I’m looking through the documentation searching something clean. In the meantime you can “square” your polygon to obtain an approximate polygon and you can add a specific event when you click it. A sort of an invisible square that acts like a button.

What i am saying is that computer science knowledge is necessary, if your going to be building an engine you need to know about physics, just knowing what a piston is not enough, and computer science to a programmer is like physics to an engineer

it makes a world of difference , and i remember when i first started programming i used to think “why would anyone make a science out of this, its redundant” but then i see now why that is so important, you have to know maths really well to be a successful programmer, besides programming languages where designed by mathematicians

my other degree is physics, and that helps me in engine design astronomically, because no amount of experience as a programmer is going to make you better prepared for engine design without physics

programming languages are nothing more than tools like a hammer or spanner is to a construction worker , however if you know mathematics , then you know the though process of how to design your software, if you know physics then you can bring art and science together into one , a programming language on its own means nothing, even if you know every single programming language but dont know mathematics you are as good as a programmer with no hands , you can try this and that but in hind site you are useless

it is so important to understand binary well, and you cant understand binary system without knowing mathematics , algorithms are so important and they also heavily rely on functions(calculus) and knowing geometrical analysis , you have to understand bounds and boundaries, and you have to have a good sense of mathematical induction which you cant develop without doing maths for a while

unless your dealing with software that a child can make then you need none of the above just to know the language

usually your dealing with software that is processing data in great chunks , reading writing to files, creating trees, libraries, manipulation files all which has to work intricately with other parts of the program and code , its just really complex, i mean just to design a system that does something as simple as moving pixels on a screen(in large chunks) is not a simple process(what i am working on) there is so much to be aware of and mathematical knowledge makes it so much easier to deal with

I prefer books. I don’t want to see a video tutorial I want to see your programs. I’m not the one acting like the special one and I’m not the one that says stupid to the other person. To make an argument you need facts: you can’t say you don’t think like me so you are stupid. Remember that you don’t know where I work. It can be a stupid company or a great one, how can you judge an entire company on the way I do interview? Tell me, do you prefer a programmer that can give you an entire software or do you prefer a programmer that can do books’ exercises? I prefer someone who can really code if he can also do exercise like yours then is a point in his favor. But if he’s only capable to do those exercise, how can I pay someone to read stackoverlfow instead of coding?

Thank you, I don’t think I will need a course, if you want to make a course for other people then make it, I don’t think I will need it…

If you say that there is nothing academic about this you have never worked as a programmer I suppose. The real mathematics problems are those of euler-project, not a simple exercise with arrays. I am referring to the only good solution that in case of size changes it doesn’t need a rewriting of the program. There is no need to copy the whole array. Don’t forget that not all programming languages where designed by mathematicians. You say that the most used language today(the ones that were not designed by mathematicians) are not serious? Before offending people get your facts straight and be respectful. If people don’t offend you why are you flaming in the first place?

This below is not the solution!!! this is a hint for the solution to help you out if you need some hints , or to get you on the right path

you got two weeks to do this and get it right, Good Luck!!! then the challenge is over, you still need to implement a lot of the code, bound checking, scanner functions, also this below is shifting whole rows, while you need to be shifting one element at a time, or if you take up the challenge implement both the one element at a time and complete rows, also the initialize functions, the random generator function, and obviously the individual element function, and direction apply and check function

#include 

#define SIZE 4

void shiftRowRight(int [][4], int, int,  int);
void shiftRowLeft(int [][4], int, int,  int);
void shiftRowDown(int [][4], int, int, int);
void shiftRowUp(int [][4], int, int, int);
void displayArray();

   //if you change size make sure to iniitalize array elements

   int arr[SIZE][SIZE]={{1,2,3,4},

Why did you take out the definitions of TRUE and FALSE in the beginning. I also tried adding #include but it it doesn’t recognize that command. Everything else looks clear to me.

[ShikhaTan]

As long as you choose the correct language to start you won’t have any problem. But remember that Java lacks a lot of things found in C. You can start the same with Java, but remember that to be a competent programmer you have to learn the things needed in C too. For some aspects C force you to program your solution yourself. If you read only tutorials and use only code written by other, like a lot of people do with Java, you will learn very little. You have to program yourself in order to really learn.

http://www.javacodegeeks.com/2011/10/top-10-java-books-you-dont-want-to-miss.html

Start with books that treat the basics of programming in Java, and after you have enough concepts start to program straight. After some time that you can tackle easily the easy challenges, concentrate on serious projects and read books aimed at improving your programming choices.

[ShikhaTan]

You don’t have to start with C. C is somewhat dead compared to other languages. If you want the basics you can still start with Java, C++, Python, Ruby etc. etc. The best language for you is the answer to this question:”What type of programs I want to do?”. If you want to program system stuff: C, C++, D, Rust will be okay. If you want to do some simple desktop apps then Java, C#, Go, Python will be the most suited etc. etc.

Start with one language and when you feel comfortable programming in it then switch to another language. If you plan to work in this industry you have to know different technologies. The fact that you have to start with C it’s a myth and can be very counterproductive. If you want an unorthodox guide you can read “Learn C the hard way”, it makes you program from the beginning.

One of the most common error of people starting is to only read/watch tutorial without programming. Everything that you read will be useless if you don’t apply it. Ask yourself what software you want to develop and pick the best suited language for it. If you don’t know what to choose, if you tell me what you want to do I can suggest you which language and books to pick.

If you have session_start() at the top of the page, then you will have a session id. And you have to assign $_SESSION variables after that. There aren’t any automatic $_SESSION variables.
