• Regular expression to process key value pairs

  - by user677680

  I am attempting to write a regular expression to process a string of key value(s) pairs formatted like so KEY/VALUE KEY/VALUE VALUE KEY/VALUE A key can have multiple values separated by a space. I want to match a keys values together, so the result on the above string would be VALUE VALUE VALUE VALUE I currently have the following as my regex [A-Z0-9]+/([A-Z0-9 ]+)(?:(?!^[A-Z0-9]+/)) but this returns VALUE KEY as the first result.

• Spawning form in new process

  - by Mike_G

  I had originally created a windows form to be a dialog of my projects main form. Now the dialog is getting complex enough that it needs to be started in its own process. Is there a way to do this in code or do i need to create a new project and link my files to it?

• Lower CPU % used by FFMPEG Process via PHP (FLV Video Conversion)

  - by BoRo

  Hi, Okay, so I currently execute an ffmpeg command via PHP to run a video conversion. The Problem I'm Having is during the conversion, the ffmpeg process(es) use up so much CPU/Processing Power (near 100%), which slows down the response of my webserver. Is there a Way (crontab or script) I can limit the ffmpeg processes to a certain CPU percentage? Thanks,

• JpegBitmapEncoder.Save() throws exception when writing image with metadata to MemoryStream

  - by Dmitry

  I am trying to set up metadata on JPG image what does not have it. You can't use in-place writer (InPlaceBitmapMetadataWriter) in this case, cuz there is no place for metadata in image. If I use FileStream as output - everything works fine. But if I try to use MemoryStream as output - JpegBitmapEncoder.Save() throws an exception (Exception from HRESULT: 0xC0000005). After some investigation I also found out what encoder can save image to memory stream if I supply null instead of metadata. I've made a very simplified and short example what reproduces the problem: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Drawing; using System.Drawing.Imaging; using System.Windows.Media.Imaging; namespace JpegSaveTest { class Program { public static JpegBitmapEncoder SetUpMetadataOnStream(Stream src, string title) { uint padding = 2048; BitmapDecoder original; BitmapFrame framecopy, newframe; BitmapMetadata metadata; JpegBitmapEncoder output = new JpegBitmapEncoder(); src.Seek(0, SeekOrigin.Begin); original = JpegBitmapDecoder.Create(src, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.OnLoad); if (original.Frames[0] != null) { framecopy = (BitmapFrame)original.Frames[0].Clone(); if (original.Frames[0].Metadata != null) metadata = original.Frames[0].Metadata.Clone() as BitmapMetadata; else metadata = new BitmapMetadata("jpeg"); metadata.SetQuery("/app1/ifd/PaddingSchema:Padding", padding); metadata.SetQuery("/app1/ifd/exif/PaddingSchema:Padding", padding); metadata.SetQuery("/xmp/PaddingSchema:Padding", padding); metadata.SetQuery("System.Title", title); newframe = BitmapFrame.Create(framecopy, framecopy.Thumbnail, metadata, original.Frames[0].ColorContexts); output.Frames.Add(newframe); } else { Exception ex = new Exception("Image contains no frames."); throw ex; } return output; } public static MemoryStream SetTagsInMemory(string sfname, string title) { Stream src, dst; JpegBitmapEncoder output; src = File.Open(sfname, FileMode.Open, FileAccess.Read, FileShare.Read); output = SetUpMetadataOnStream(src, title); dst = new MemoryStream(); output.Save(dst); src.Close(); return (MemoryStream)dst; } static void Main(string[] args) { string filename = "Z:\\dotnet\\gnom4.jpg"; MemoryStream s; s = SetTagsInMemory(filename, "test title"); } } } It is simple console application. To run it, replace filename variable content with path to any .jpg file without metadata (or use mine). Ofc I can just save image to temporary file first, close it, then open and copy to MemoryStream, but its too dirty and slow workaround. Any ideas about getting this working are welcome :)

• Animated background image in a hidden <div> doesn't load or loads not animated

  - by Guanche

  Hello, I have spent the whole day trying to make a script which on "submit" hides the form and shows hidden with animated progress bar. The problem is that Internet Explorer doesn't show animated gif images in hidden divs. The images are static. I visited many websites and found a script which uses: document.getElementById(id).style.backgroundImage = 'url(/images/load.gif)'; Finally, my script works in Internet Explorer, Firefox, Opera but... Google Chrome doesn't display the image at all. I see only div text. After many tests I discovered the following: the only way to see the background image in Google Chrome is to include the same image somewhere in the page (outside of hidden div) with 1px dimensions: <img src="/images/load.gif" width="1" heigh="1" /> This did the trick but... after this dirty solution Microsoft Explorer for some reason shows the image as static again. So, my question is: is there any way how to force Gogle Chrome to show the image? Thanks. This is my script: <script language="JavaScript" type="text/javascript"> function ver (id, elementId){ if (document.getElementById('espera').style.visibility == "visible") { return false; }else{ var esplit = document.forms[0]['userfile'].value.split("."); ext = esplit[esplit.length-1]; if (document.forms[0]['userfile'].value == '') { alert('Please select a file'); return false; }else{ if ((ext.toLowerCase() == 'jpg')) { document.getElementById(id).style.position = 'absolute'; document.getElementById(id).style.display = 'inline'; document.getElementById(id).style.visibility = "visible"; document.getElementById(id).style.backgroundImage = 'url(/images/load.gif)'; document.getElementById(id).style.height = "100px"; document.getElementById(id).style.backgroundColor = '#f3f3f3'; document.getElementById(id).style.backgroundRepeat = "no-repeat"; document.getElementById(id).style.backgroundPosition = "50% 50%"; var element; if (document.all) element = document.all[elementId]; else if (document.getElementById) element = document.getElementById(elementId); if (element && element.style) element.style.display = 'none'; return true; }else{ alert('This is not a jpg file'); return false; } } } } </script> <div id="frmDiv"> <form enctype="multipart/form-data" action="/upload.php" method="post" name="upload3" onsubmit="return ver('espera','frmDiv');"> <input type="hidden" name="max_file_size" value="4194304" /> <table border="0" cellspacing="1" cellpadding="2" width="100%"> <tr bgcolor="#f5f5f5"> <td>File (jpg)</td> <td> <input type="file" name="userfile" class="upf" /></td></tr> <tr bgcolor="#f5f5f5"> <td>&nbsp;</td> <td> <input class="upf2" type="submit" name="add" value="Upload" /> </td></tr></table></form> </div> <div id="espera" style="display:none;text-align:center;float:left;width:753px;">&nbsp;<br />&nbsp;<br />&nbsp;<br />&nbsp;<br /> &nbsp;<br />Please wait...<br />&nbsp; </div>

Do I need to convert image data into Unicode? Any suggestions , if someone can find what I am doing wrong that would be very helpful to me.

  I am interested to print image from iPhone programmatically using bluetooth printer device. In one of the sample code I have implemented code for Text print but in that sample I am not getting how to convert image into format, like unsigned char buffer3[796]={ 0x55 , 0x66 , 0x77 , 0x88 , 0x44 , 0x1B , 0x58 , 0x31 , 0x19, 0x20, 0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x80 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x01 ,0xC0 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x01 ,0x80 ,0x00 ,0x03 ,0x60 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x03 ,0xA0 ,0x00 ,0x07 ,0xB0 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x05 ,0x60 ,0x00 ,0x07 ,0xD8 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x05 ,0xA0 ,0x00 ,0x13 ,0xEC ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x04 ,0x20 ,0x00 ,0x29 ,0xF4 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x03 ,0xC0 ,0x00 ,0x64 ,0xF9 ,0x00 ,0x0F ,0xFF ,0x9C ,0x01 ,0xC0 ,0x19 ,0xFF ,0xC0 ,0x7F ,0xFC ,0x7F ,0xF9 ,0xC0 ,0x3D ,0xFF ,0xF1 ,0xFF ,0xE3 ,0xFF ,0xC0 ,0x00 ,0x00 ,0xF2 ,0x73 ,0x80 ,0x0F ,0xFF ,0x9C ,0x01 ,0xC0 ,0x19 ,0xFF ,0xC0 ,0x7F ,0xFE ,0x7F ,0xFD ,0xE0 ,0x3D ,0xFF ,0xF1 ,0xFF ,0xE3 ,0xFF ,0xC0 ,0x00 ,0x00 ,0x79 ,0x26 ,0xC0 ,0x0F ,0xFF ,0xDC ,0x01 ,0xC0 ,0x19 ,0xFF ,0xC0 ,0x7F ,0xFE ,0xFF ,0xFD ,0xF0 ,0x7D ,0xFF ,0xFB ,0xFF ,0xF7 ,0xFF ,0xE0 ,0x00 ,0x03 ,0x3C ,0x8F ,0x60 ,0x0C ,0x01 ,0xDC ,0x01 ,0xC0 ,0x19 ,0x80 ,0x00 ,0x70 ,0x0E ,0xE0 ,0x1D ,0xF0 ,0x7D ,0x80 ,0x3B ,0x80 ,0x77 ,0x00 ,0xE0 ,0x00 ,0x04 ,0x9E ,0x8F ,0xB0 ,0x0E ,0x01 ,0xDC ,0x01 ,0xC0 ,0x19 ,0x80 ,0x00 ,0x70 ,0x0E ,0xE0 ,0x1D ,0xF8 ,0xFD ,0x80 ,0x33 ,0x80 ,0x77 ,0x00 ,0xE0 ,0x00 ,0x0E ,0x4F ,0x27 ,0xD8 ,0x0F ,0xFF ,0x9C ,0x01 ,0xC0 ,0x19 ,0xFF ,0xC0 ,0x7F ,0xFC ,0xE0 ,0x1D ,0xF9 ,0xFD ,0xFF ,0xF3 ,0x80 ,0x77 ,0x00 ,0xE0 ,0x00 ,0x0F ,0x26 ,0x53 ,0xC8 ,0x0F ,0xFF ,0x9C ,0x01 ,0xC0 ,0x19 ,0xFF ,0xC0 ,0x7F ,0xFC ,0xEF ,0xFD ,0xDD ,0xDD ,0xFF ,0xF3 ,0x80 ,0x77 ,0x00 ,0xE0 ,0x00 ,0x07 ,0x90 ,0xC9 ,0xF0 ,0x0F ,0xFF ,0xDC ,0x01 ,0xC0 ,0x19 ,0xFF ,0xC0 ,0x7F ,0xFE ,0xEF ,0xFD ,0xDF ,0x9D ,0xFF ,0xFB ,0x80 ,0x77 ,0x00 ,0xE0 ,0x00 ,0x03 ,0xC9 ,0xE4 ,0xE0 ,0x0C ,0x00 ,0xDC ,0x01 ,0xC0 ,0x19 ,0x80 ,0x00 ,0x70 ,0x06 ,0xE7 ,0xFD ,0xCF ,0x9D ,0x80 ,0x3B ,0x80 ,0x77 ,0x00 ,0xE0 ,0x00 ,0x01 ,0xF0 ,0xF2 ,0x40 ,0x0E ,0x01 ,0xDC ,0x00 ,0xC0 ,0x19 ,0x80 ,0x00 ,0x70 ,0x0E ,0xE0 ,0x1D ,0xCF ,0x1D ,0x80 ,0x3B ,0x80 ,0x77 ,0x00 ,0xE0 ,0x00 ,0x00 ,0xE6 ,0x79 ,0x00 ,0x0F ,0xFF ,0xDF ,0xFC ,0xFF ,0xF9 ,0xFF ,0xC0 ,0x7F ,0xFE ,0xE0 ,0x1D ,0xC7 ,0x1D ,0xFF ,0xFB ,0xFF ,0xF7 ,0xFF ,0xE0 ,0x00 ,0x00 ,0x49 ,0x3D ,0x00 ,0x0F ,0xFF ,0x9F ,0xFC ,0xFF ,0xF9 ,0xFF ,0xC0 ,0x7F ,0xFE ,0xE0 ,0x1D ,0xC2 ,0x1D ,0xFF ,0xF1 ,0xFF ,0xE3 ,0xFF ,0xC0 ,0x00 ,0x00 ,0x1C ,0x9E ,0x00 ,0x0F ,0xFF ,0x1F ,0xFC ,0x7F ,0xE1 ,0xFF ,0xC0 ,0x7F ,0xFC ,0xE0 ,0x1D ,0xC0 ,0x1D ,0xFF ,0xE0 ,0xFF ,0xC1 ,0xFF ,0x80 ,0x00 ,0x00 ,0x1E ,0x4C ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x0F ,0x20 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x07 ,0x90 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x03 ,0xE0 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x01 ,0xC0 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x80 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 ,0x00 };

  I'm trying to allow users to upload images and then store the images, base64 encoded, in firebase. I'm trying to make my firebase structured as follows: |--Feed |----Feed Item |------username |------epic |---------name,etc. |------images |---------image1, image 2, etc. However, I can't get the remote data in firebase to mirror the local data in the client. When I print the array of images to the console in the client, it shows that the uploaded images have been added to the array of images...but these images never make it to firebase. I've tried doing this multiple ways to no avail. I tried using implicit syncing, explicit syncing, and a mixture of both. I can;t for the life of me figure out why this isn;t working and I'm getting pretty frustrated. Here's my code: $scope.complete = function(epicName){ for (var i = 0; i < $scope.activeEpics.length; i++){ if($scope.activeEpics[i].id === epicName){ var epicToAdd = $scope.activeEpics[i]; } } var epicToAddToFeed = {epic: epicToAdd, username: $scope.currUser.username, userImage: $scope.currUser.image, props:0, images:['empty']}; //connect to feed data var feedUrl = "https://epicly.firebaseio.com/feed"; $scope.feed = angularFireCollection(new Firebase(feedUrl)); //add epic var added = $scope.feed.add(epicToAddToFeed).name(); //connect to added epic in firebase var addedUrl = "https://epicly.firebaseio.com/feed/" + added; var addedRef = new Firebase(addedUrl); angularFire(addedRef, $scope, 'added').then(function(){ // for each image uploaded, add image to the added epic's array of images for (var i = 0, f; f = $scope.files[i]; i++) { var reader = new FileReader(); reader.onload = (function(theFile) { return function(e) { var filePayload = e.target.result; $scope.added.images.push(filePayload); }; })(f); reader.readAsDataURL(f); } }); } EDIT: Figured it out, had to connect to "https://epicly.firebaseio.com/feed/" + added + "/images"

• Running cmd commands via .NET?

  - by a2h

  System.Diagnostics.Process proc0 = new System.Diagnostics.Process(); proc0.StartInfo.FileName = "cmd"; proc0.StartInfo.WorkingDirectory = Path.Combine(curpath, "snd"); proc0.StartInfo.Arguments = omgwut; And now for some background... string curpath = System.IO.Path.GetDirectoryName(Application.ExecutablePath); omgwut is something like this: copy /b t.wav + y.wav + p.wav + e.wav + space.wav + i.wav + n.wav + space.wav + s.wav + o.wav + m.wav + e.wav + space.wav + t.wav + e.wav + x.wav + t.wav + space.wav + h.wav + e.wav + r.wav + e.wav + space.wav + a.wav + n.wav + d.wav + space.wav + p.wav + y.wav + r.wav + o.wav + space.wav + w.wav + i.wav + l.wav + l.wav + space.wav + s.wav + h.wav + o.wav + w.wav + space.wav + h.wav + i.wav + s.wav + space.wav + r.wav + e.wav + n.wav + d.wav + i.wav + t.wav + o.wav + n.wav + space.wav output.wav And nothing happens at all. So obviously something's wrong. I also tried "copy" as the executable, but that doesn't work.

• Process: Unable to start service com.google.android.gms.checkin.CheckinService with Intent

  - by AndyRoid

  I'm trying to build a Google map application but keep receiving this in my LogCat. I have all the permissions and meta-data set in my manifest, but am still dumbfounded by this error. Have looked everywhere on SO for this specific error but found nothing relating to com.google.android.gms.checkin A little bit about my structural hierarchy. MainActivity extends ActionBarActivity with three tabs underneath actionbar. Each tab has it's own fragment. On the gMapFragment I create a GPSTrack object from my GPSTrack class which extends Service and implements LocationListener. The problem is that when I start the application I get this message: I have all my libraries imported properly and I even added the google-play-services.jar into my libs folder. I also installed Google Play Services APKs through CMD onto my emulator. Furthermore the LocationManager lm = = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); in my GPSTrack class always returns null. Why is this and how can I fix these issues?

• Display a Photo Gallery using Asp.Net and SQL

  - by sweetcoder

  I have recently added photos to my SQL database and have displayed them on an *.aspx page using Asp:Image. The ImageUrl for this control stored in a separate *.aspx page. It works great for profile pictures. I have a new issue at hand. I need each user to be able to have their own photo gallery page. I want the photos to be stored in the sql database. Storing the photos is not difficult. The issue is displaying the photos. I want the photos to be stored in a thumbnail grid fashion, when the user clicks on the photo, it should bring up the photo on a separate page. What is the best way to do this. Obviously it is not to use Asp:Image. I am curious if I should use a Gridview. If so, how do I do that and should their be a thumbnail size stored in the database for this? Once the picture is click on how does the other page look so that it displays the correct image. I would think it is not correct to send the photoId through the url. Below is code from the page I use to display profile pictures. protected void Page_Load(object sender, EventArgs e) { string sql = "SELECT [ProfileImage] FROM [UserProfile] WHERE [UserId] = '" + User.Identity.Name.ToString() + "'"; string strCon = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["SocialSiteConnectionString"].ConnectionString; SqlConnection conn = new SqlConnection(strCon); SqlCommand comm = new SqlCommand(sql, conn); conn.Open(); Response.ContentType = "image/jpeg"; Response.BinaryWrite((byte[])comm.ExecuteScalar()); conn.Close(); }

• JPEG artifacts removal in C#

  - by Arcturus

  Hi all I am building a website for a club that is part of a mother organisation. I am downloading (leeching ;) ) the images that where put on profile pages of the mother organisation to show on my own page. But their website has a nice white background, and my website has a nice gray gradient on the background. This does not match nicely. So my idea was to edit the images before saving them to my server. I am using GDI+ to enhance my images, and when I use the method MakeTransparent of Bitmap, it does work, and it does do what its supposed to do, but I still have these white jpeg artifacts all over the place. The artifacts makes the image so bad, I am better off not making the image transparent and just leaving it white, but thats really ugly on my own website. I can always at a nice border with a white background of course, but I rather change the background to transparent. So I was wondering if and how I can remove some simple JPEG artifacts in C#. Has anyone ever done this before? Thanks for your time. Example image: Transformed image:

• GPGPU programming with OpenGL ES 2.0

  - by Albus Dumbledore

  I am trying to do some image processing on the GPU, e.g. median, blur, brightness, etc. The general idea is to do something like this framework from GPU Gems 1. I am able to write the GLSL fragment shader for processing the pixels as I've been trying out different things in an effect designer app. I am not sure however how I should do the other part of the task. That is, I'd like to be working on the image in image coords and then outputting the result to a texture. I am aware of the gl_FragCoords variable. As far as I understand it it goes like that: I need to set up a view (an orthographic one maybe?) and a quad in such a way so that the pixel shader would be applied once to each pixel in the image and so that it would be rendering to a texture or something. But how can I achieve that considering there's depth that may make things somewhat awkward to me... I'd be very grateful if anyone could help me with this rather simple task as I am really frustrated with myself. UPDATE It seems I'll have to use an FBO, getting one like this: glBindFramebuffer(...)

• IE7 CSS bug aligning <img> with text in a <ul>

  - by Artem Russakovskii

  I've been banging my ahead on this IE7 bug for the last few days and it's time to resort to the mind of the crowd. I have the following HTML and CSS: http://beerpla.net/for_www/ie7_test/test.html The goal is to have a <ul>, with each <li> containing a small icon and some text. Multiline text would be aligned to itself and not wrap under the image. I've tried using float:left on the image and a bunch of other things, and finally I thought the position:absolute would work for sure but in IE7 I consistently see the text pop off to the next line and get misaligned with the image: This is what I expect it to look like: I even tried to make the div display:inline which kind of worked but then started wrapping under the image for long lines, so it was no good. zoom:1 also produced a similar effect. I'm at a loss at the moment. This code works fine in all other browsers. IE7 is a special, very special child. Any ideas? Thank you. Edit: If you have IE8, you can emulate IE7 by pressing F12 and then Alt-7.

• Deciding between Apache Commons exec or ProcessBuilder

  - by Moev4

  I am trying to decide as to whether to use ProcessBuilder or Commons exec, My requirements are that I am simply trying to create a daemon process whose stdout/stdin/stderr I do not care about. In addition I want to execute a kill to destroy this process when the time comes. I am using Java on Linux. I know that both have their pains and pitfalls (such as being sure to use separate thread to swallow streams can lead to blocking or deadlocks, and closing the streams so not to leave open files hanging around)and wanted to know if anyone had suggestions one way or the other as well as any good resources to follow.

• Automatically generate table of function pointers in C.

  - by jeremytrimble

  I'm looking for a way to automatically (as part of the compilation/build process) generate a "table" of function pointers in C. Specifically, I want to generate an array of structures something like: typedef struct { void (*p_func)(void); char * funcName; } funcRecord; /* Automatically generate the lines below: */ extern void func1(void); extern void func2(void); /* ... */ funcRecord funcTable[] = { { .p_func = &func1, .funcName = "func1" }, { .p_func = &func2, .funcName = "func2" } /* ... */ }; /* End automatically-generated code. */ ...where func1 and func2 are defined in other source files. So, given a set of source files, each of which which contain a single function that takes no arguments and returns void, how would one automatically (as part of the build process) generate an array like the one above that contains each of the functions from the files? I'd like to be able to add new files and have them automatically inserted into the table when I re-compile. I realize that this probably isn't achievable using the C language or preprocessor alone, so consider any common *nix-style tools fair game (e.g. make, perl, shell scripts (if you have to)). But Why? You're probably wondering why anyone would want to do this. I'm creating a small test framework for a library of common mathematical routines. Under this framework, there will be many small "test cases," each of which has only a few lines of code that will exercise each math function. I'd like each test case to live in its own source file as a short function. All of the test cases will get built into a single executable, and the test case(s) to be run can be specified on the command line when invoking the executable. The main() function will search through the table and, if it finds a match, jump to the test case function. Automating the process of building up the "catalog" of test cases ensures that test cases don't get left out (for instance, because someone forgets to add it to the table) and makes it very simple for maintainers to add new test cases in the future (just create a new source file in the correct directory, for instance). Hopefully someone out there has done something like this before. Thanks, StackOverflow community!

• Build Issue with multi module project

  - by vijay.shad

  Hi, I have a multi module web project. Four modules of the project are packaged as jar and added as dependency to the fifth module, which is packaged as war. When it is time to deploy the application i just run package on the war project and my war is created with all the dependencies. Now there is a problem. One of the my module have heavy changes. Now when i created war for my projects these changes was not reflected in the output war file(the jar in lib folder of war has still the old code). Can you please point the things i am missing from the release process? Why the old code is being packaged with the war? Can you please point some good resource for real file build process using maven? Regards, Vijay

• IE6 background-position(?) issue

  I apply to stackoverflow as my last resort. I got this ie6 bug while using the image at the background of the link. It seems that ie6 scrolls the background. How can I avoid it?

• How do laziness and I/O work together in Haskell?

  - by Bill

  I'm trying to get a deeper understanding of laziness in Haskell. I was imagining the following snippet today: data Image = Image { name :: String, pixels :: String } image :: String -> IO Image image path = Image path <$> readFile path The appeal here is that I could simply create an Image instance and pass it around; if I need the image data it would be read lazily - if not, the time and memory cost of reading the file would be avoided: main = do image <- image "file" putStrLn $ length $ pixels image But is that how it actually works? How is laziness compatible with IO? Will readFile be called regardless of whether I access pixels image or will the runtime leave that thunk unevaluated if I never refer to it? If the image is indeed read lazily, then isn't it possible I/O actions could occur out of order? For example, what if immediately after calling image I delete the file? Now the putStrLn call will find nothing when it tries to read.

• How to stop Lean programming becoming Cowboy Coding?

  - by Matt Howells

  My team has been progressively adopting more and more lightweight methodologies, moving from Scrum to Lean/Kanban where there is less and less formal process. At some point we will be back to Cowboy Coding; indeed I fear we may already be on the border line. Where can the line be drawn between a very lightweight Lean and Agile process and anarchy? How will we know when we have crossed the line? And how can we prevent ourselves from crossing the line? The question might also be phrased as, 'what processes cannot be safely eliminated in Lean's drive to eliminate waste'?

• J2ME cache issue

  - by kiennt

  I have to write a J2ME app to retrieve images from server and display in mobile phone. I have seen and test that Snaptu have a mechanism to cache image, event with 100 images (both normal size and zoom size). I wonder how they can do that? I though that those guys use rms to save image stream to data. But when i check in working folder of simulater( I use Windows XP and Sun Wireless Toolkit 3.0, the Emulator device i use to run my program is CLDC Device 1 - my working folder is C:\Document And Settings\Administrator\javame-sdk\3.0\work\6\appdb), i see some .db file. When i delete these files, i still can view cache image in my emulator???? I also thought that those guys use heap memory to save image. But it is not correct because when i set limit device memory is 2MB (like some mobile phones), and i load and view 100 images in zoom size, it didn't make OutOfMemory Error? It so weird. Any one can help me? Thanks

• Something like jQuery's .resizable but without the div's inside

  - by Brendon Muir

  Hi everyone, this is just a quick probe to see if this is technically possible. I'm wanting to enable the resizing of an image in the browser (also within a contentEditable area). Firefox and IE already allow this to be done with their inbuilt handles and it works fine. I'm wanting to implement something for Safari however because it doesn't support this natively. I've had a go with jQuery's resizable method and it does a very good job, however it relies on inserting a bunch of div's along with the image and wrapping that in a big div. This would normally be fine if we weren't concerned with the code generated in the contentEditable area, but we are because it's going to be saved back to the server. I could strip this extra stuff out on save, but I was thinking, is it technically possible to create a resizing script for images that doesn't rely on adding extra div's? Even if we decide to go without handles for now, and just concentrate on detecting when a user is close to the edge of the image, change the mouse cursor to a resizing one, and detect clicks and drags in the 5px's around the edge of the image, is this possible? If it's possible, I'm assuming (hoping) that perhaps it's already been done, but my searching hasn't turned up anything so far. Keen to hear any ideas :)
