问题 I'm learning about graphs(they seem super useful) and was wondering if I could get some advice on a possible way to structure my graphs. Simply, Lets say I get purchase order data everyday and some days its the same as the day before and on others its different.

问题 This is one of those "pretty sure we found the answer, but hoping we're wrong" questions. We are looking at a steganography problem and it's not pretty. Situation: We have a series of images. We want to mark them (watermark) so the watermarks survive a series of conditions. The kicker is, we are using a lossfull format, JPG, rather than lossless such as PNG. Our watermarks need to survive screenshotting and, furthermore, need to be invisible to the naked eye. Finally, they need contain at

问题 I have a dataset, made up of a mask file, and a data file. the mask file tells the decoder whether there are 8 bits per field present, or 4, for the current offset of the datafile. I need to shift the data out according to the mask, and write the decoded file, with all 8 bits per field. I'm trying to accomplish this in C. void shift_4bits_left(unsigned char* array, unsigned short size) { int i; unsigned char shifted = 0x00; unsigned char overflow = (0xF0 & array[0]) >> 4; for (i = (size - 1);

问题 I'm working on an app in which PayPal payment gateway is to integrate. As such I have gone through several blog but did not found it helpful.
