  • Dynamically created jagged rectangular array

    - by gagar1n
    In my project I have a lot of code like this: int[][] a = new int[firstDimension][]; for (int i=0; i<firstDimension; i++) { a[i] = new int[secondDimension]; } Types of elements are different. Is there any way of writing a method like createArray(typeof(int), firstDimension, secondDimension); and getting new int[firstDimension][secondDimension]? Once again, type of elements is known only at runtime.

  • Git: Can I commit my working directory to a new branch without commiting it to a current branch?

    - by Noli
    Somewhat new at Git.. I am working on a project, and had all of my tests passing on the master branch. I then made some changes, and when everything started failing, I realized that maybe I should have made those changes in a different branch. Is there I way I can commit the changes to a new branch without commiting them to my master branch, so that the master still has my passing tests?

  • Should I use PHP or PHP + J2EE?

    - by Sean Xiong
    I'm going to start a new project with instant message support. I find that there is no good long polling solution in PHP, but there is some good ones in J2EE. I'm wondering if I can integrate PHP and J2EE to get the function? Or should I just use J2EE instead of PHP? Thanks.

  • What's the point of Mono on Windows

    - by Adam Haile
    This may be a dumb question...but I was just looking into the Mono project and they have a section about installing Mono on Windows. But, since Windows obviously already has the .NET runtime can anyone tell me what exactly is the point of having Mono for Windows? Does it help with cross platform development or something?

  • Another IKImageView Question: copying a region

    - by Brian Postow
    I'm trying to use the select and copy feature of the IKImageView. If all you want to do is have an app with an image, select a portion and copy it to the clipboard, it's easy. You set the copy menu pick to the first responder's copy:(id) method and magically everything works. However, if you want something more complicated, like you want to copy as part of some other operation, I can't seem to find the method to do this. IKImageView doesn't seem to have a copy method, it doesn't seem to have a method that will even tell you the selected rectangle! I have gone through Hillegass' book, so I understand how the clipboard works, just not how to get the portion of the image out of the view... Now, I'm starting to think that I made a mistake in basing my project on IKImageView, but it's what Preview is built on (or so I've read), so I figured it had to be stable... and anyway, now it's too late, I'm too deep in this to start over... So, other than not using IKImageView, any suggestions on how to copy the select region to the clipboard manually? EDIT actually, I have found the copy(id) method, but when I call it, I get <Error>: CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 16 bits/pixel; 1-component color space; kCGImageAlphaPremultipliedLast; 2624 bytes/row. Which obviously doesn't happen when I do a normal copy through the first-responder... I understand the error message, but I'm not sure where it's getting those parameters from... Is there any way to trace through this and see how this is happening? A debugger won't help for obvious reasons, as well as the fact that I'm doing this in Mozilla, so a debugger isn't an option anyway... EDIT 2 It occurs to me that the copy:(id) method I found may be copying the VIEW rather than copying a chunk of the image to the clipboard, which is what I need. The reason I thought it was the clipboard copy is that in another project, where I'm copying from an IKImageView to the clipboard straight from the edit menu, it just sends a copy:(id) to the firstResponder, but I'm not actually sure what the firstresponder does with it...

  • iPhone memory leaks with store kit

    - by Nareshkumar
    Hello, I am trying to develop an application which uses storekit api. The document (Store Kit guide) suggests that the api will not work on a simulator. I found out that memory leaks will not be able to work on a device. I was wondering if any one can tell me how to check for memory leaks while using a store kit api on a project? How is it possible?

  • When should I use Dependency Injection and when utility methods?

    - by Roman
    I have a Java EE project with Spring IoC container. I've just found in Utils class static method sendMail(long list of params). I don't know why but I feel that it would look better if we had separate class (Spring bean with singleton scope) which will be responsible for sending email. But I can't find any arguments which can prove my position. So, are there any pros (or cons) in using DI in this (rather general) situation?

  • Spring to understand properties in YAML

    - by litius
    Did Spring abandon YAML to use as an alternative to .properties / .xml because of: [Spring Developer]: ...YAML was considered, but we thought that counting whitespace significant was a support nightmare in the making... [reference from spring forum] I am confident YAML makes a lot of sense for properties, and I am using it currently on the project, but have difficulties to inject properties in a <property name="productName" value="${client.product.name}" /> fashion. Anything I am missing, or I should create a custom YamlPropertyPlaceholderConfigurer ? Thank you, /Anatoly

  • Generating video or images of geometrical objects from data

    - by Jonathan Barbero
    Hello, I'm working in a course's project to predict the velocity and position of the solar system planets (and other objects). It will be really cool if I can visualize the predicted objects data, if it's possible generating 3D images, if in video that's amazing. Do you know any library that lets me to use this data to generate an image or video? (I don't care in which language) Data: - simulation step (time line step for a video) - positions of the objects - radius and/or colours of the objects Thanks in advance, any suggestion is welcome.

  • Writing csv files with python with exact formatting parameters

    - by Ben Harrison
    I'm having trouble with processing some csv data files for a project. The project's programmer has moved onto greener pastures, and now I'm trying to finish the data analysis up (I did/do the statistical analysis.) The programmer suggested using python/csv reader to help break down the files, which I've had some success with, but not in a way I can use. This code is a little different from what I was trying before. I am essentially attempting to create an array. In the raw data format, the first 7 rows contain no data, and then each column contains 50 experiments, each with 4000 rows, for 200000 some rows total. What I want to do is take each column, and make it an individual csv file, with each experiment in its own column. So it would be an array of 50 columns and 4000 rows for each data type. The code here does break down the correct values, I think the logic is okay, but it is breaking down the opposite of how I want it. I want the separators without quotes (the commas and spaces) and I want the element values in quotes. Right now it is doing just the opposite for both, element values with no quotes, and the separators in quotes. I've spent several hours trying to figure out how to do this to no avail, import csv ifile = open('00_follow_maverick.csv') epistemicfile = open('00_follower_maverick_EP.csv', 'w') reader = csv.reader(ifile) colnum = 0 rownum = 0 y = 0 z = 8 for column in reader: rownum = 4000 * y + z for element in column: writer = csv.writer(epistemicfile) if y <= 50: y = y + 1 writer.writerow([element]) writer.writerow(',') rownum = x * y + z if y > 50: y = 0 z = z + 1 writer.writerow(' ') rownum = x * y + z if z >= 4008: break What is going on: I am taking each row in the raw data file in iterations of 4000, so that I can separate them with commas for the 50 experiments. When y, the experiment indicator here, reaches 50, it resets back to experiment 0, and adds 1 to z, which tells it which row to look at, by the formula of 4000 * y + z. When it completes the rows for all 50 experiments, it is finished. The problem here is that I don't know how to get python to write the actual values in quotes, and my separators outside of quotes. Any help will be most appreciated. Apologies if this seems a stupid question, I have no programming experience, this is my first attempt ever. Thank you.

  • What defines writing PHP?

    - by cdburgess
    When writing PHP code for any given project, do you find you can write code off the top of your head? Or do you make multiple round trips to php.net? If it is the later, can you still be considered a good coder. This is a legitimate question as I find I have difficulty always remembering all of the functions that are available to me so I find I use php.net as a crutch. Is there anyway to improve this?

  • Override a resource from standard assembly in ASP.NET

    - by wRAR
    I want to override a string from a System.ComponentModel.DataAnnotations for an ASP.NET project. Do I need to make a satellite assembly, messing with custom build tasks, al.exe etc.? Even if yes, I couldn't find how to convert .resx to .resources to feed it to al.exe. And if no, where to put the .resx. and how to name it?
