  • The OpenGL standard allows individual vendors to provide additional functionality through extensions as new technology is created. Extensions may introduce new functions and new constants, and may relax or remove restrictions on existing OpenGL functions. Each vendor has an alphabetic abbreviation that is used in naming their new functions and constants. For example, NVIDIA's abbreviation (NV) is used in defining their proprietary function glCombinerParameterfvNV() and their constant GL_NORMAL_MAP_NV.

Model-view-controller - Wikipedia, the free encyclopedia - 0 views

  • MVC is often seen in web applications, where the view is the actual HTML or XHTML page, and the controller is the code that gathers dynamic data and generates the content within the HTML or XHTML. Finally, the model is represented by the actual content, which is often stored in a database or in XML nodes, and the business rules that transform that content based on user actions.

      i think this is like PHP or ASP page .... you just See HTML (view) that is Generated by PHP/ASP Code (controller) that gather data from Database (content)

  • Memorize the value of pi You should always try to remember the value of pi as far as possible, 3.1415926535897932384626433832795, certainly the part in italics. The judges may not give the value in the question, and if you use values like 22/7 or 3.1416 or 3.142857, then it is very likely that some of the critical judge inputs will cause you to get the wrong answer. You can also get the value of pi as a compiler-defined constant or from the following code: Pi=2*acos(0)

      hhhhhhhhhhh ...... awl mara a3rf el mawdo3 dah we awl mara a3raf en el Pi = 2*acos(0)
  • You cannot always check the equality of floating point numbers with the = = operator in C/C++. Logically their values may be same, but due to precision limit and rounding errors they may differ by some small amount and may be incorrectly deemed unequal by your program
  • #define swap(xxx, yyy) (xxx) ^= (yyy) ^= (xxx) ^= (yyy)
    • Islam TeCNo
       
      I remember someone told me that it's impossible to do swaping using macros :D ...but i think it's possible

  • But recursion should not be discounted completely, as some problems are very easy to solve recursively (DFS, backtracking)
    • Islam TeCNo
       
      Some problems are much easier when using recursion
  • Having a good understanding of probability is vital to being a good programmer

  • So bone up on JavaScript, CSS, and HTML to succeed over the next five years
  • Every top-flight developer I’ve met recommends learning at least one dynamic or functional programming language to learn new ways of thinking, and from personal experience, I can tell you that it works.
  •  
    1: One of the "Big Three" (.NET, Java, PHP) 2: Rich Internet Applications (RIAs) 3: Web development 4: Web services 5: Soft skills 6: One dynamic and/or functional programming language 7: Agile methodologies 8: Domain knowledge 9: Development "hygiene" 10: Mobile development

What is Domain Name Resolution - 0 views

  • Hosts File - There is a file called the HOSTS file that you can use to convert domain names to IP addresses. Entries in the HOSTS file override any mappings that would be resolved via a DNS server
    • Islam TeCNo
       
      I think this is what some spam and adware programs use .... you type a normal site Name but you go yo another site ... i think so !!
  • Netbios - This only applies to Windows machines and will only be used to map names to IP addresses if all previous methods failed. This method will attempt to map the netbios name you are trying to connect to with an IP address.
    • Islam TeCNo
       
      any body can explain this point for me ?
  • This can be changed though by changing certain registry keys
    • Islam TeCNo
       
      start -> run -> regedit this will allow you to edit the registry

  • DnsPriority = 30 LocalPriority = 200 HostsPriority = 75 NetbtPriority = 100

      Or Simpler DnsPriority = 1 HostsPriority = 2 NetbtPriority = 3 LocalPriority = 4

  • TCP Transmission Control Protocol UDP User Datagram Protocol
    • Islam TeCNo
       
      The Diffrance between TCP and UDP is that TCP check the packet that packets are sent correctly ... but UDP just send and don't check ....so UDP is faster than TCP but TCP check that data is sent correctly .... so UDP is used in applications like Video Streaming (You Tube) and Voice Streaming too
