Visual Studio 2012 Web Publish doesn't copy files
...ncorrectly assumed that they would be the
same (e.g. Solution's Release|x86 would have each project set to
Release|x86 as well), which caused us to use the wrong build
properties for publishing files.
The workaround is to make the solution configuration and build
configuration match. Th...
Is gcc's __attribute__((packed)) / #pragma pack unsafe?
...ntially unsafe on some systems. The symptom probably won't show up on an x86, which just makes the problem more insidious; testing on x86 systems won't reveal the problem. (On the x86, misaligned accesses are handled in hardware; if you dereference an int* pointer that points to an odd address, it...
Why is processing a sorted array faster than processing an unsorted array?
...hless - Random
seconds = 3.113581453
// Branchless - Sorted
seconds = 3.186068823
Observations:
With the Branch: There is a huge difference between the sorted and unsorted data.
With the Hack: There is no difference between sorted and unsorted data.
In the C++ case, the hack is actually a tad sl...
What is the difference between the kernel space and the user space?
...
CPU rings are the most clear distinction
In x86 protected mode, the CPU is always in one of 4 rings. The Linux kernel only uses 0 and 3:
0 for kernel
3 for users
This is the most hard and fast definition of kernel vs userland.
Why Linux does not use rings 1 and 2: ...
How to automatically generate a stacktrace when my program crashes

/lib64/tls/libc.so.6(__libc_start_main+0xdb)[0x3a9b91c4bb]
./test[0x40086a]
This shows the load module, offset, and function that each frame in the stack came from. Here you can see the signal handler on top of the stack, and the libc functions before main in addition to main, foo, bar, and b...
What are some resources for getting started in operating system development? [closed]
...ks after this brief overview of what is involved in writing an OS for the X86 platform.
The link that appears to be most promising (www.nondot.org/sabre/os/articles) is no longer available, so you'll need to poke through the Archive.org version to read it.
At the end of the day the bootloader take...
Failed to load the JNI shared Library (JDK)
... Correctly! My laptop is running on x64 OS but I installed x86 JDK. Just installed x64 jdk and the issue go away. Thanks.

What is exactly the base pointer and stack pointer? To what do they point?
...by adding and subtracting, respectively, a constant offset from ebp. All x86 calling conventions define ebp as being preserved across function calls. ebp itself actually points to the previous frame's base pointer, which enables stack walking in a debugger and viewing other frames local variables ...
How exactly does the callstack work?
...r variable c. The offset is negative because the stack grows downwards on x86. The next operation stores c in EAX: EAX is moved to ESI, cout is moved to EDI and then the insertion operator is called with cout and c being the arguments.
Finally,
The return value of main is stored in EAX: 0. That i...
Enabling WiFi on Android Emulator
...at it works with the Image Android 7.1.1 (Google Apis), API Level 25, ABI x86. The strange thing is that it does not work with newer Images: e.g. API 27, ABI x86 (Here I can enable Wi-Fi, but it will switch back to off automatically)
