  • What is the difference between printf() and puts() in C?

    - by alex
    First up, I should let you know that I am learning C, so my apologies if this question seems stupid to a more advanced developer. I know you can print with printf() and puts(). I can also see that printf() allows you to embed variables inside and do some stuff like formatting. Is puts() merely a primitive version of printf(). Should it be used for every possible printf() without string interpolation? Thanks

  • How can I find the boundaries of a subset of a sorted list?

    - by Alex
    I have the following dilemma: I have a list of strings, and I want to find the set of string which start with a certain prefix. The list is sorted, so the naive solution is this: Perform binary search on the prefixes of the set, and when you find an element that starts with the prefix, traverse up linearly until you hit the top of the subset. This runs in linear time, however, and I was wondering if anyone can suggest a more efficient way to do it.

  • Printing a JFrame and its components

    - by Alex Terreaux
    I have been working in a big program and one of its functionalities should be to print the contents of the main window. I checked the API and found this example: http://docs.oracle.com/javase/tutorial/2d/printing/gui.html it was very helpful, I tried to use that code in my program by placing this inside the actionperformed method of my print button: PrinterJob job = PrinterJob.getPrinterJob(); job.setPrintable(this); boolean ok = job.printDialog(); if (ok) { try { job.print(); } catch (PrinterException ex) { /* The job did not successfully complete */ } } If I click the print button, I get a printer dialog and when I tell it to print, it just prints a blank document. I know the above code is not all I need, as I've seen in the API's examples there is a print() method, but apparently they never call it, so it is pretty confusing. I've tried calling and using it many times, but with no success. Also, I think that when I finally get it to print, my window will need to be printed in the landscape orientation, it even may need some scaling. Any ideas on how to do that? I would like any useful help to help me implement this code successfully. I know I should be able to do it by myself just by checking the documentation (I've tried for almost 2 days now) but I can't get it to work. I've learned all the programming I know through the internet. Any help will be greatly appreciated.

  • endpoints (bug?) behavior in xts

    - by Alex
    If I try to get endpoints for every year, for example, and do the following: xts.data <- xts(1:10000, order.by=seq(from=as.Date("1970-01-01"), by=1, len=10000)) z <- endpoints(xts.data, on="months", k=12) The return value for this is: > z [1] 0 10000 Same with numbers higher than 12. Why would xts simply not return indices of every year or 13th month starting from the beginning. Is it limited by the number of periods in a year? That is if i did: z <- endpoints(xts.data, on="weeks", k=54) This seems to work fine.

  • Translate sequence in macro parameters to separate macros

    - by Alex Tiger
    How to acces each element in macro if the definition is like MACRO(name, seq) and the code is like: MACRO("TheName", (Elem1) (Elem2) (Elem3) ) I want to generate the next code: MACRO("TheName", ELEMMACRO(Elem1) ELEMMACRO(Elem2) ELEMMACRO(Elem3) ) Or something like that. In other words, I want to process every parameter separately (I don't care of definition, even if it will be something like MACRO("TheName", Elem1, Elem2, Elem3 ) There could be more elements, there could be less. I have tried V_ARGS (I need it only for gcc), but I can only copy all the elements by that, not to process them separately. What can I do? P.S. Because of some reasons, I can't use Boost.

  • Java / MySQL - How to access connection from another class?

    - by Alex
    I'm just getting my head around java (and OOP for that matter), the only thing I am familiar with is MySQL. I need to keep the DB connection open throughout the duration of the application, as well as a server socket. I'm not even sure if they both need separate classes, but here's what I have so far: http://pastebin.com/qzMFFTrY (it wouldn't all go in a code tag) The variable I need is con for line 86.

  • jquery $.ajax load in UI dialog() problem

    - by alex
    i have a working bing Image search api with jsonp datatype. It's working with no problems. When i load the image search script in a Jquery UI dialog, it display properly and i'm able to search and see the results in the dialog() box. But if i close the dialog() and open it again, now if i search no results show. Looking at console.log, i do confirm the jason data is recieved, but for some reason it's not appending to the result div, so i see no result on the screen. This onyl happens if i close the dialog and open it again. If i refresh refresh the page and open the dialog again then search results are displayed. This is what i'm using to append the results. $.each(data.SearchResponse.Image.Results, function(i, item) { console.log(item.Thumbnail.Url); $("#Results").append("<li><img style='width:100px; height:75px;' src='" + item.Thumbnail.Url + "'/></li>"); });

  • What is most efficient way of setting row to zeros for a sparce scipy matrix?

    - by Alex Reinking
    I'm trying to convert the following MATLAB code to Python and am having trouble finding a solution that works in any reasonable amount of time. M = diag(sum(a)) - a; where = vertcat(in, out); M(where,:) = 0; M(where,where) = 1; Here, a is a sparse matrix and where is a vector (as are in/out). The solution I have using Python is: M = scipy.sparse.diags([degs], [0]) - A where = numpy.hstack((inVs, outVs)).astype(int) M = scipy.sparse.lil_matrix(M) M[where, :] = 0 # This is the slowest line M[where, where] = 1 M = scipy.sparse.csc_matrix(M) But since A is 334863x334863, this takes like three minutes. If anyone has any suggestions on how to make this faster, please contribute them! For comparison, MATLAB does this same step imperceptibly fast. Thanks!
