• IBM Toolkit for MPEG-4 terms of use, am I understanding right?

  - by Tom Brito

  The IBM Toolkit for MPEG-4 comes with the following paragraph in its licence: Rights In Data You assign to IBM all right, title, and interest (including ownership of copyright) in any data, suggestions, and written materials that 1) is related to Your use of the Program and 2) You provide to IBM. If IBM requires it, You will sign an appropriate document to assign such rights. Neither party will charge the other for rights in data or any work performed as a result of this Agreement. Correct me if I am wrong, but I'm understanding that I cannot use their toolkit without give them rights on my software?

• Design cache mechanism

  - by Delashmate

  Hi All, I got assignment to write design for cache mechanism, This is my first time writing a design document, Our program display images for doctors, and we wan't to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

• g++: how to specify preference of library path?

  - by Heinrich Schmetterling

  I'm compiling a c++ program using g++ and ld. I have a .so library I want to be used during linking. However, a library of the same name exists in /usr/local/lib, and ld is choosing that library over the one I'm directly specifying. How can I fix this? For the examples below, my library file is /my/dir/libfoo.so.0. Things I've tried that don't work: my g++ command is "g++ -g -Wall -o my_binary -L/my/dir -lfoo bar.cpp" adding /my/dir to the beginning or end of my $PATH env variable adding /my/dir/libfoo.so.0 as an argument to g++ Thanks.

• What is a good balance for having developers learn at work

  - by Mel

  So now I am the manager. One of the things I always promised myself I would do is have the other developers focus on learning new stuff. In fact I even want to force them to read a couple books that really helped me learn to program. However now I am also accountable for the product getting finished. I have this vision of everyone reading books instead of working and me getting fired. What is the best way to work learning into the developers schedules, especially for the ones that just don't care to learn. How much time should be spent on learning in a work week?

• Cross version line matching.

  - by BCS

  I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

• successives operations with C++

  - by Tayeb Ghagha

  How can I perform this code: if a number n is divisible by 3, add 4 to n; if n is not divisible by 3 but by 4, divise n by 2; if n is not divisible by 3, not by 4, make n=n-1. The problem with me is that I don't know how to make this successively. For example: with the number 6, I have to have: 6, 10, 9, 13, 12, 16, 8, 4, 2, 1 et 0 6+4=10; 10-1=9; 9+4=13; 13-1=12; 12+4=16; 16/2=8.....0 This makes 10 operations. So my program has to return: 6---10 Thank you for help

• What is the best, python or bash for selectively concatenating lots of files?

  - by Werner

  Hi, I have around 20000 files coming from the output of some program, and their names follow the format: data1.txt data2.txt ... data99.txt data100.txt ... data999.txt data1000.txt ... data20000.txt I would like to write a script that gets as input argument the number N. Then it makes blocks of N concatenated files, so if N=5, it would make the following new files: data_new_1.txt: it would contain (concatenated) data1.txt to data5.txt (like cat data1.txt data2.txt ... data_new_1.txt ) data_new_2.txt: it would contain (concatenated) data6.txt to data10.txt ..... I wonder what do you think would be the best approach to do this, whether bash, python or another one like awk, perl, etc. The best approach I mean in terms of simplest code. Thanks

• Any custom/third party Visual C# text box Controls with extra features?

  - by PlaZmaZ

  I'm writing a program that uses the textbox in visual C# to read a log file. When dealing with very large amounts of text, writing to the textbox is incredibly slow. The textbox also lacks many features. Are there any custom textbox controls that are faster, or even a sort of embedded editor (with ability to highlight certain words, indent, input bookmarks)? Many of the features I want are programmable, but it would be nice if there was a faster textbox or one that already had these features :) Thanks.

• Importing data from many excel workbooks and sheets into a single workbook/table

  - by Max Rusalen

  Hi, I have 54 excel files with three sheets each, each sheet has a different amount of data entries but they are set out in a identical format, and I need to import the data from those sheets into a single workbook using VBA. Is there any way I can program it so I can build the loops to import the data, but without having to write in each workbook name for each loop/sheet? I think I can use the call function, but I don't know how to make the loop codes independent of the workbook name they apply to. Thank you so much in advance, Millie

• how to adjust sliding of scroll according to the value calculated by me?

  - by cng

  I am working on scroll. I have made a program wherein if the scroll box is in particular range of the panel then it automatically moves to a particular position in the slider. For eg, I have a panel of size 500. the scroll has height of 100. Now the total intervals are 5. Now if i slide the scroll box at a position 225 then i want that it automatically slides to the start of that interval that is at position 200. or if i slide to position 450 then instead of staying there it goes to position 400. Is it possible?

• Why does GC.GetTotalMemory() report huge memory allocations?

  - by Seventh Element

  I have been playing around with GC.GetTotalMemory(). When I create a local variable of type Titles in the example below, the consumed amount of memory increases by 6276 bytes. What's going on here? class Program { enum Titles { Mr, Ms, Mrs, Dr }; static void Main(string[] args) { GetTotalMemory(); Titles t = Titles.Dr; GetTotalMemory(); } static void GetTotalMemory() { long bytes = GC.GetTotalMemory(true); Console.WriteLine("{0}", bytes); } }

• (C++) While reading a file (ifstream), is there any way to direct it to make a new line?

  - by Enzo

  While reading a file (ifstream), is there any way to direct it to make a new line? For instance, I would like for THIS to happen: myfilearray[1]array[2]endl; Obviously, the "endl" just isn't allowed. Is there another way to do this? Edit---thanks for the quick responses guys! From a text file, I'm trying to store two strings from that file into arrays and then do the same with the next line (or until I desire, using a for loop) Using strings is important to me as it will make my future program a lot more flexible.

• Color getAlpha() not working as intended

  - by Arvy

  I was making a program where I load an image and after that I do something with opaque pixels. Transparent pixels showed up as black pixels, but after some time I found the cause: Color c = new Color (input.getRGB(x, y)); Works-> if ((input.getRGB(x, y) & 0xFF000000) != 0x00000000) { do_smth();} Returns true at all times-> if (c.getAlpha() != 0) { do_smth(); } So why it does not work?

• How can I edit a js file sent by the server before it gets to my browser?

  - by pstone

  During a normal browsing session I want to edit a specific javascript file before the browser receives since once it gets there it's impossible to edit. Is there are any tool for this? For what I need it I can't just save it and edit it on my disk. I'm ready to learn how to program it myself but if anyone can point out more or less what I have to do I'd be very grateful. I'd have to intercept the packets until I have the whole file while blocking the browser from receiving it any part of it, then edit it manually and forward it to the same port. I don't think I can do this by just using pcap, I've read a bit about scapy but I'm not sure if it can help me either. Thanks in advance.

• iPhone view architecture question

  - by Joe

  So I have (for instance) three views: A: root view B: a view functionally identical to root C: a data entry view which collects a few piece of info What I'm trying to do is reuse C to supply the data it collects to either A or B. It should supply the data to whichever of the two it is pushed onto. The data for A is similar, but functionally distinct, to what collects for B. Right now, I'm passing data from C to A or B via a singleton class. What I'm trying to avoid is having two instances of C, one to supply data to A and B (because, in actuality, the program will have 5 total views like C. Does the question make sense?

• Enter custom file name to be read ?

  - by ZaZu

  Hello, I want to allow users to type the name of any .txt file to be read/written. This is my code : printf("Enter .txt file name\n"); scanf("%s",&fname); FILE *inputf; inputf=fopen(&fname,"w"); Problem is this method does not work (having &fname) as a parameter. I can imagine its because C needs "filename.txt" for it work ... even if I enter for example : "custom.txt", the program returns an error of "Storage block not big enough for this operation" What is the correct method to accomplish this ? Im using C and im pretty much using basic commands .. (not too advanced) Thanks alot !!!

• Undefined reference to "func" when compiled with GCC

  - by hotlemontea

  I implement a link list in two files in linklist.h and linklist.c, and I call some functions defined in linklist.h in main function of main.c. linklist.h is included in both linklist.c and main.c. When I compile this program by GCC with Makefile, the error named "undefined reference to xxx" occurs. I think my Makefile is written correctly as below. So what is the possible reason for this linking error CC=gcc CFLAGS= -g -O2 TARGET=target OBJECTS=main.o linklist.o TARGET: $(OBJECTS) $(CC) $(CFLAGS) $(OBJECTS) -o $(TARGET) clean: rm target $(OBJECTS) main.o:linklist.h linklist.o:linklist.h

• How to copy/install assembly in a GAC? (Some problem running NUnit)

  - by prosseek

  I have NUnit installed at this directory. C:\Program Files\NUnit 2.5.5\bin\net-2.0 I made the directory beneath a GAC. C:\Windows\Microsoft.NET\assembly\GAC_MSIL\NUnit and copied the nunit.framework.dll, but I got the same error. When I try to run my unit test (mut.dll) in some random directory. I get the following error. I have to copy the mut.dll under the NUnit directory in order to run it. ProcessModel: Default DomainUsage: Single Execution Runtime: net-2.0 Could not load file or assembly 'nunit.framework, Version=2.5.5.10112, Culture=n eutral, PublicKeyToken=96d09a1eb7f44a77' or one of its dependencies. The system cannot find the file specified. What went wrong? How can I install/copy the assembly inside a GAC?

• index was outside the bounds of the array because of \n (new line) in richTextBox

  - by revvs

  If i go into the next line with richTextBox1.Text + "\n" you can't use richTextBox with anything anymore normally. Why not ? because index will be outside the bounds of the array and you won't be able to transport the data into database or work with it normally...it will be all messed up. It is like the story with cin and getline in C++, but much worse. Here you won't see errors, not until you'll try to transport it into database. If you use "\n" to write new lines into txt, your txt will be also unusable. It will look like up to the byte the same as if you would write it by hand same sentences but "\n" will fuck it up. So how do i go into the next line and not have this "\n" screwing up my program ??! How do i go into the new line ?
