  • Who Needs a Scanner? Scan a Document to PDF With Your Android Phone

    - by Chris Hoffman

This is perfect for receipts or any other physical documents you run across that you might want to read later. No need to save all those business cards, pamphlets and other pieces of paper — just scan them with your smartphone’s camera.

  • Connect Digest : 2011-03-12

    - by AaronBertrand
    Background Last year, I came to a very tough decision that I would cease publicizing Connect items in an attempt to drive up votes and get important issues fixed. This was almost entirely due to a couple of MVPs criticizing me for raising awareness of certain Connect items instead of letting them be found "naturally." I wasn't sure what world they were living in, where droves of everyday end users just happened to stumble upon Connect items without any prompting. I suppose it could be said that the...(read more)

  • Identifying which pattern fits better.

    - by Daniel Grillo
    I'm developing a software to program a device. I have some commands like Reset, Read_Version, Read_memory, Write_memory, Erase_memory. Reset and Read_Version are fixed. They don't need parameters. Read_memory and Erase_memory need the same parameters that are Length and Address. Write_memory needs Lenght, Address and Data. For each command, I have the same steps in sequence, that are something like this sendCommand, waitForResponse, treatResponse. I'm having difficulty to identify which pattern should I use. Factory, Template Method, Strategy or other pattern. Edit I'll try to explain better taking in count the given comments and answers. I've already done this software and now I'm trying to refactoring it. I'm trying to use patterns, even if it is not necessary because I'm taking advantage of this little software to learn about some patterns. Despite I think that one (or more) pattern fits here and it could improve my code. When I want to read version of the software of my device, I don't have to assembly the command with parameters. It is fixed. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. To read a portion of the memory (maximum of 256 bytes), I have to assembly the command using the parameters Len and Address. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. To write a portion in the memory (maximum of 256 bytes), I have to assembly the command using the parameters Len, Address and Data. So I have to send it. After wait for response. If there is a response, treat (or parse) it and returns. I think that I could use Template Method because I have almost the same algorithm for all. But the problem is some commands are fixes, others have 2 or 3 parameters. I think that parameters should be passed on the constructor of the class. But each class will have a constructor overriding the abstract class constructor. Is this a problem for the template method? Should I use other pattern?

    - by NoviceCoding
    I am a freshman in college and doing a software engineering/ finance double major. I've been learning programming on my own and have a good bit of familiarity with php by now.

  • C++ converting binary(P5) image to ascii(P2) image (.pgm)

    - by tubby
    I am writing a simple program to convert grayscale binary (P5) to grayscale ascii (P2) but am having trouble reading in the binary and converting it to int. #include <iostream> #include <fstream> #include <sstream> using namespace::std; int usage(char* arg) { // exit program cout << arg << ": Error" << endl; return -1; } int main(int argc, char* argv[]) { int rows, cols, size, greylevels; string filetype; // open stream in binary mode ifstream istr(argv[1], ios::in | ios::binary); if(istr.fail()) return usage(argv[1]); // parse header istr >> filetype >> rows >> cols >> greylevels; size = rows * cols; // check data cout << "filetype: " << filetype << endl; cout << "rows: " << rows << endl; cout << "cols: " << cols << endl; cout << "greylevels: " << greylevels << endl; cout << "size: " << size << endl; // parse data values int* data = new int[size]; int fail_tracker = 0; // find which pixel failing on for(int* ptr = data; ptr < data+size; ptr++) { char t_ch; // read in binary char istr.read(&t_ch, sizeof(char)); // convert to integer int t_data = static_cast<int>(t_ch); // check if legal pixel if(t_data < 0 || t_data > greylevels) { cout << "Failed on pixel: " << fail_tracker << endl; cout << "Pixel value: " << t_data << endl; return usage(argv[1]); } // if passes add value to data array *ptr = t_data; fail_tracker++; } // close the stream istr.close(); // write a new P2 binary ascii image ofstream ostr("greyscale_ascii_version.pgm"); // write header ostr << "P2 " << rows << cols << greylevels << endl; // write data int line_ctr = 0; for(int* ptr = data; ptr < data+size; ptr++) { // print pixel value ostr << *ptr << " "; // endl every ~20 pixels for some readability if(++line_ctr % 20 == 0) ostr << endl; } ostr.close(); // clean up delete [] data; return 0; } sample image - Pulled this from an old post. Removed the comment within the image file as I am not worried about this functionality now. When compiled with g++ I get output: $> ./a.out a.pgm filetype: P5 rows: 1024 cols: 768 greylevels: 255 size: 786432 Failed on pixel: 1 Pixel value: -110 a.pgm: Error The image is a little duck and there's no way the pixel value can be -110...where am I going wrong? Thanks.

  • Current activity logger

    - by user72605
    Very inexperienced coder here: Does anyone know of an app (for iOS or Mac) that asks for my current activity every hour or so? I see tons of apps that let you log your activities, but none that use popups/notifications to actively ask you. I found a script that looks promising (source), but I'm having trouble implementing it so that it repeats every hour: #!/bin/bash echo What are you doing right now? read -e what echo `date` - $what >> timelog.txt Thanks!

  • Know more about Assembly

    If you want to know what an assembly does, you can use Reflector to refactor the assembly and check the codes. If you want to know why binding assembly failed, you can use Assembly Binding Log Viewer to check it. Also you should set HKLM\Software\Microsoft\Fusion\ForceLog registry value to 1 . When the assembly is used, you want to know what the assembly uses, you can use Process Explorer ....(read more)
