reverse-engineering

I would like to know how GCC implements exception handling for C++ programs. I couldn't find an easy-to-understand and self-explanatory article on the Web (although there are many such articles for Visual C++). All I know is that GCC's implementation is called DWARF exception handling. I have written a small C++ program and translated it into assembly with the command: g++ main.cpp -S -masm=intel -fno-dwarf2-cfi-asm The main.cpp and main.s files are given here. Could anyone please explain the contents of the main.s file, especially the sections .gcc_except_table and .eh_frame line-by-line? (My

I'm curious if it's possible for me to write programs that can control an Apple TV, specifically an Apple TV 4th gen running tvOS 9.1.1, like Apple's Remote app for iOS can. I'd like to send it commands for navigating in the four cardinal directions, selecting an item on the screen, going up the navigation stack -- essentially what Apple's Remote app can do. Has anyone done any work reverse engineering the protocol it uses? Cursory Googling only has so far yielded out of date results about earlier generation Apple TVs and the DAAP protocol which looks like something different than what I want.

I have an android apk and I deleted my source code and dont have the project again, I want to change the version code of the old apk. my question is how do I unzip and repack the apk so I can use the. am using a mac system. I saw so many things for windows but i couldnt find for mac.I need help please You want to use APKTool. It will handle the unzip and rebuild for you: http://ibotpeaches.github.io/Apktool/ The simplest method is executing unzip command: unzip xxx.apk -d xxx A directory xxx will be generated to store unzipped files. Actually, .apk files are same as .zip files. Execute command

There are lots of PE file browsers. Here is a list of good ones if you are interested: PE File format viewers: PE Explorer http://www.pe-explorer.com/ PE VIew: http://www.magma.ca/~wjr/ PEBrowse Professional http://www.smidgeonsoft.prohosting.com/pebrowse-pro-file-viewer.html PE Browse Professional Interactive - http://www.smidgeonsoft.prohosting.com/pebrowse-pro-interactive-debugger.html I'm still working on windows & I want to view the ELF files. Are there any tools? I'm googling but couldn't find any till now. bdmcbri readelf and objdump are both excellent utilities if you are on a Unix box

public main main proc near push ebp mov ebp, esp and esp, 0FFFFFFF0h sub esp, 30h mov dword ptr [esp], 8 ; size call _malloc mov [esp+2Ch], eax mov dword ptr [esp+4], 4 mov eax, [esp+2Ch] mov [esp], eax call __start The code above represents a portion of a large project I am working on. I am trying to reverse this code into C equivalent but I am having difficulty understanding how malloc works. I am figuring 8 bytes would be the size of the memory being allocated; however, I am not sure about this line. mov eax, [esp+2ch] What does malloc do to eax? Furthermore would this be equivalent C code?

Photoshop has a lot of cool artistic filters , and I'd love to understand the underlying algorithms. One algorithm that's particularly interesting is the Cutout filter (number 2 at the link above). It has three tunable parameters, Number of Levels, Edge Simplicity, and Edge Fidelity. Number of levels appears to drive a straightforward posterization algorithm, but what the other sliders do technically eludes me. I would think that they're doing something related to Vornoi diagrams or k-means partitionion, but poking around on wikipedia hasn't resulted in anything that maps obviously to what

As it currently stands, this question is not a good fit for our Q&A format.

Are they any good tools out there to reverse engineer a SWF file? Thanks. Disassemble the SWF with Flasm . Note: Only works for flash 8 or earlier unfortunately. SWFTools might

(I apologize if this is the wrong place to ask this. I think it's definitely programming related, though if this belongs on some other site please let me know) I grew up playing Pokémon Red and Blue, games that were great fun but are somewhat notorious for having numerous exploitable glitches (for example, see this ridiculous speedrun of the game that uses memory corruption to turn the item screen into a hex editor). Recently, I found an interesting speedrun of the game that uses a glitch called the "ZZAZZ glitch" to corrupt important memory locations and allow the player to almost immediately
