  • Primary language - C++/Qt, C#, Java?

    - by Airjoe
    I'm looking for some input, but let me start with a bit of background (for tl;dr skip to end). I'm an IT major with a concentration in networking. While I'm not a CS major nor do I want to program as a vocation, I do consider myself a programmer and do pretty well with the concepts involved. I've been programming since about 6th grade, started out with a proprietary game creation language that made my transition into C++ at college pretty easy. I like to make programs for myself and friends, and have been paid to program for local businesses. A bit about that- I wrote some programs for a couple local businesses in my senior year in high school. I wrote management systems for local shops (inventory, phone/pos orders, timeclock, customer info, and more stuff I can't remember). It definitely turned out to be over my head, as I had never had any formal programming education. It was a great learning experience, but damn was it crappy code. Oh yeah, by the way, it was all vb6. So, I've used vb6 pretty extensively, I've used c++ in my classes (intro to programming up to algorithms), used Java a little bit in another class (had to write a ping client program, pretty easy) and used Java for some simple Project Euler problems to help learn syntax and such when writing the program for the class. I've also used C# a bit for my own simple personal projects (simple programs, one which would just generate an HTTP request on a list of websites and notify if one responded unexpectedly or not at all, and another which just held a list of things to do and periodically reminded me to do them), things I would've written in vb6 a year or two ago. I've just started using Qt C++ for some undergrad research I'm working on. Now I've had some formal education, I [think I] understand organization in programming a lot better (I didn't even use classes in my vb6 programs where I really should have), how it's important to structure code, split into functions where appropriate, document properly, efficiency both in memory and speed, dynamic and modular programming etc. I was looking for some input on which language to pick up as my "primary". As I'm not a "real programmer", it will be mostly hobby projects, but will include some 'real' projects I'm sure. From my perspective: QtC++ and Java are cross platform, which is cool. Java and C# run in a virtual machine, but I'm not sure if that's a big deal (something extra to distribute, possibly a bit slower? I think Qt would require additional distributables too, right?). I don't really know too much more than this, so I appreciate any help, thanks! TL;DR Am an avocational programmer looking for a language, want quick and straight forward development, liked vb6, will be working with database driven GUI apps- should I go with QtC++, Java, C#, or perhaps something else?

  • Codeigniter not returning me to upload form after image upload.

    - by Drew
    I'm still very new to codeigniter. The issue i'm having is that the file uploads fine and it writes to the database without issue but it just doesn't return me to the upload form. Instead it stays in the do_upload and doesn't display anything. Even more bizarrely there is some source code behind the scenes. Can someone tell my what it is i'm doing wrong because I want to be returning to my upload form after submission. Thanks in advance. Below is my code: Controller: function do_upload() { if($this->Upload_model->do_upload()) { $this->load->view('home/upload_form'); }else{ $this->load->view('home/upload_success', $error); } } Model: function do_upload() { $config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = '2000'; $this->load->library('upload', $config); if ( ! $this->upload->do_upload()) { $error = array('error' => $this->upload->display_errors()); return $error; } else { $data = $this->upload->data(); $full_path = 'uploads/' . $data['file_name']; $spam = array( 'image_url' => $full_path, 'url' => $this->input->post('url') ); $id = $this->input->post('id'); $this->db->where('id', $id); $this->db->update('NavItemData', $spam); return true; } } View (called upload_form): <html> <head> <title>Upload Form</title> </head> <body> <?php if(isset($buttons)) : foreach($buttons as $row) : ?> <h2><?php echo $row->image_url; ?></h2> <p><?php echo $row->url; ?></p> <p><?php echo $row->name; ?></p> <p><?php echo anchor("upload/update_nav/$row->id", 'edit'); ?></p> <?php endforeach; ?> <?php endif; ?> </body> </html>

  • Is there anything like deal() for normal MATLAB arrays?

    - by jjkparker
    When dealing with cell arrays, I can use the deal() function to assign cells to output variables, such as: [a, b, c] = deal(myCell{:}); or just: [a, b, c] = myCell{:}; I would like to do the same thing for a simple array, such as: myArray = [1, 2, 3]; [a, b, c] = deal(myArray(:)); But this doesn't work. What's the alternative?

  • How to build jars from IntelliJ properly?

    - by ripper234
    I have a project that contains a single module, and some dependencies. I'd like to create a jar, in a separate directory, that contains the compiled module. In addition, I'd like to have the dependencies present beside my module. No matter how I twist IntelliJ's "build jar" process, the output of my module appears empty (besides a META-INF file).

  • CSS Hidden DIV Form Submit

    - by Michael
    Using CSS, when a link is clicked it brings up a hidden DIV that contains a form. The user will then enter information and then submit the form. I'd like the hidden DIV to remain visisble, and a 'success message' to be displayed after submission. Then the user will have the option of closing the DIV. I can't get it to work without reloading the page, which causes the DIV to become hidden again. Any ideas? <body> <a href="javascript:showDiv()" style="color: #fff;">Click Me</a> <!--POPUP--> <div id="hideshow" style="visibility:hidden;"> <div id="fade"></div> <div class="popup_block"> <div class="popup"> <a href="javascript:hideDiv()"> <img src="images/icon_close.png" class="cntrl" title="Close" /> </a> <h3>Remove Camper</h3> <form method="post" onsubmit="email.php"> <p><input name="Name" type="text" /></p> <p><input name="Submit" type="submit" value="submit" /></p> </form> <div id="status" style="display:none;">success</div> </div> </div> </div> <!--END POPUP--> <script language=javascript type='text/javascript'> function hideDiv() { if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById('hideshow').style.visibility = 'hidden'; } else { if (document.layers) { // Netscape 4 document.hideshow.visibility = 'hidden'; } else { // IE 4 document.all.hideshow.style.visibility = 'hidden'; } } } function showDiv() { if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById('hideshow').style.visibility = 'visible'; } else { if (document.layers) { // Netscape 4 document.hideshow.visibility = 'visible'; } else { // IE 4 document.all.hideshow.style.visibility = 'visible'; } } } </script> </body>

  • Is it possible to publish component revisions within workflow?

    - by Ianthe
    Our current setup is that we have two targets, Staging and Live. Collaborators may update the affected component while it is still within the workflow. A final activity is set to publish the related pages to Live. Is it possible to publish component updates (revisions e.g. 2.2, 2.5) to Staging from within the workflow? The TOM API documentation for Page.Publish() method does not seem to have an input parameter to fullfil such purpose.

  • Modify audio pitch of recorded clip (m4v)

    - by devcube
    I'm writing an app in which I'm trying to change the pitch of the audio when I'm recording a movie (.m4v). Or by modifying the audio pitch of the movie afterwards. I want the end result to be a movie (.m4v) that has the original length (i.e. same visual as original) but with modified sound pitch, e.g. a "chipmunk voice". A realtime conversion is to prefer if possible. I've read alot about changing audio pitch in iOS but most examples focus on playback, i.e. playing the sound with a different pitch. In my app I'm recording a movie (.m4v / AVFileTypeQuickTimeMovie) and saving it using standard AVAssetWriter. When saving the movie I have access to the following elements where I've tried to manipulate the audio (e.g. modify the pitch): audio buffer (CMSampleBufferRef) audio input writer (AVAssetWriterAudioInput) audio input writer options (e.g. AVNumberOfChannelsKey, AVSampleRateKey, AVChannelLayoutKey) asset writer (AVAssetWriter) I've tried to hook into the above objects to modify the audio pitch, but without success. I've also tried with Dirac as described here: Real Time Pitch Change In iPhone Using Dirac And OpenAL with AL_PITCH as described here: Piping output from OpenAL into a buffer And the "BASS" library from un4seen: Change Pitch/Tempo In Realtime I haven't found success with any of the above libs, most likely because I don't really know how to use them, and where to hook them into the audio saving code. There seems to be alot of librarys that have similar effects but focuses on playback or custom recording code. I want to manipulate the audio stream I've already got (AVAssetWriterAudioInput) or modify the saved movie clip (.m4v). I want the video to be unmodifed visually, i.e. played at the same speed. But I want the audio to go faster (like a chipmunk) or slower (like a ... monster? :)). Do you have any suggestions how I can modify the pitch in either real time (when recording the movie) or afterwards by converting the entire movie (.m4v file)? Should I look further into Dirac, OpenAL, SoundTouch, BASS or some other library? I want to be able to share the movie to others with modified audio, that's the reason I can't rely on modifying the pitch for playback only. Any help is appreciated, thanks!

  • Running ssh-keygen without human interaction?

    - by Marco
    Would it be possible to run ssh-keygen without human interaction? I have a shell script that takes care of server deployment from start to finish, but ssh-keygen is the only remaining piece that still requires my input. Would it be possible to feed the parameters to it? Or is there something similar to debconf-set-selections that could be used for this? *running Debian
