Today I will show you how to use the MMX instructions. SSE stands for Streaming SIMD Extensions and uses 128-bit registers: XMM0 XMM1 XMM2 XMM3 XMM4 XMM5 XMM6 XMM7 The capabilities of the XMM registers are: 2 64-bit floating points (double precision) 2 64-bit integers 4 32-bit floating points (single-precision)… Continue Reading Programming with FASM – divide / multiply in Linux – part 009 .
Today I start programming a firefox extension. After some research and tests, I saw this is not a simple issue and I create this first tutorial about Programming extension with Firefox. I created a folder named myx and I add with two files: manifest.json and myx.js. The first file named… Continue Reading Web – Programming extension with Firefox – part 001 .
I haven’t worked with FASM, Linux, and system functions for a while. Here is an extremely simple example for beginners with output on my nickname: mythcat.
format ELF executable 3
segment readable executable
BYTES = 255 ;number of byte 255
;read a char from input
mov ebx,0 ;0 stdin, 1 stdout, 2 stderr
;write byte read to output
;exit from program
mov eax,1 ; System call 'exit'
xor ebx,ebx ; 'xor ebx,ebx'
segment readable writeable
char_Buffer db BYTES dup(0)
CharRead db 1
The result is … as follows:
[mythcat@desk fasm]$ ./fasm char_write.asm
flat assembler version 1.73.24 (16384 kilobytes memory)
3 passes, 428 bytes.
[mythcat@desk fasm]$ ./char_write
The tutorial for today is about debugging and FASM with fdbg tool. For debugging and testing you can use any debugger, but you can use the You can here all version for these operating system: GUI for Windows x64, Windows x64, Linux x64 and UEFI x64. I used the Linux… Continue Reading Programming with FASM – the format ELF executable – part 007 .
The tutorial for today will show you how to use an authentication app for two-factor authentication on Facebook with 2FA features. This method use 2FA features provide by software and produce a new numeric code every 30-seconds. The application-based 2FA solutions are available for mobile, wearables, or desktop platforms —… Continue Reading Windows – Microsoft authenticator and authentication on Facebook with 2FA features.
