Hexspeak


       hexhandHexspeak sama halnya dengan leetspeak, bisa dikatakan semi-alay haha… tapi tanpa disadari ini terkandung hampir disemua peralatan komputer yang sedang kita pakai sekarang ini.

      Hexspeak dibuat dan diambil dari

heksadesimal dimana meliputi angka 0123456789ABCDEF, dimana “0“mewakil huruf O, “1” mewakili” huruf L atau saya (I am), “5” mewakili S, dan “6” atau “9” mewakili G atau g.

       Banyak prosesor komputer, sistem operasi, dan debugger menggunakan magic number/angka ajaib, terutama sebagai magic debug value. Berikut contohnya :

    * 0x8BADF00D ("ate bad food") is used by Apple in iOS crash reports, when an application takes too long to launch, terminate, or respond to system events. 
    * 0xABADBABE ("a bad babe") is used by Apple as the "Boot Zero Block" magic number.[citation needed]
    * 0x1BADB002 ("I bad boot") Multiboot header magic number.
    * 0xBAADF00D ("bad food") is used by Microsoft’s LocalAlloc(LMEM_FIXED) to indicate uninitialised allocated heap memory when the debug heap is used.[citation needed]
    * 0xBADCAB1E ("bad cable") Error Code returned to the Microsoft eVC debugger when connection is severed to the debugger.[citation needed]
    * 0xBADDCAFE ("bad cafe") is used by ‘watchmalloc’ in OpenSolaris to mark allocated but uninitialized memory.[citation needed]
    * 0xBEADFACE ("bead face, or face bead") Is the pattern that fills all unused memory locations in the Motorola 68HCS12DP256 micro-controller simulator, SimHC12.[citation needed]
    * 0xCAFEBABE ("cafe babe") is used by Mach-O to identify Universal object files, and by the Java programming language to identify Java bytecode class files.[2]
    * 0xCAFED00D ("Cafe Dude") is used by Java as a magic number for their pack200 compression.[citation needed]
    * 0xD15EA5E ("disease") is a flag that indicates regular boot on the Nintendo GameCube and Wii consoles.[3][4]
    * 0xDEADBABE ("Dead Babe") is used by IBM Jikes RVM as a sanity check of the stack of the primary thread [5]
    * 0xDEADBEEF ("dead beef") is used by IBM RS/6000 systems, Mac OS on 32-bit PowerPC processors and the Commodore Amiga as a magic debug value. On Sun Microsystems’ Solaris, it marks freed kernel memory. On OpenVMS running on Alpha processors, DEAD_BEEF can be seen by pressing CTRL-T. The DEC Alpha SRM console has a background process that traps memory errors, identified by PS as "BeefEater waiting on 0xdeadbeef".[6]
    * 0xDEADDEAD ("dead dead") is the bug check (STOP) code displayed when invoking a Blue Screen of Death either by telling the kernel via the attached debugger, or by using a special keystroke combination[7]. This is usually seen by driver developers, as it is used to get a memory dump on Windows NT based systems. An alternative to 0xDEADDEAD is the bug check code 0x000000E2[8], as they are both called MANUALLY_INITIATED_CRASH as seen on the Microsoft Developer Network.
    * 0xDEADFA11 ("dead fall") is used by Apple in iOS crash reports, when user force quit the application.[9]
    * 0xDEFEC8ED ("defecated") is the magic number for OpenSolaris core dumps.[10]
    * 0xFACEFEED ("face feed") is used by Alpha servers running Windows NT. The Alpha Hardware Abstraction Layer (HAL) generates this error when it encounters a hardware failure.[11]
    * 0xFEE1DEAD ("feel dead") is used as a magic number in the Linux reboot system call.[12]
    * 0xFEEDFACE ("feed face") is used as a header for Mach-O binaries, and as an invalid pointer value for ‘watchmalloc’ in OpenSolaris.[citation needed]
    * 0xC0FFEE ("coffee") is used in 24-bit byte DSP like Motorola 56303.
