  • How to install programs downloaded from the internet?

    - by Rosamunda Rosamunda
    I've downloadad the latest XAMPP file, to install it into Ubuntu 13.04. After downloading the file, I just can run it. I've double click it (and I've tried right click and clicking "open", whith the same result). All the answer I get is this message: Could not display “xampp-linux-1.8.3-1-installer.run”. There is no application installed for “executable” files. Do you want to search for an application to open this file? I've tried searching for an application, with no result... Also, I haven't found any questions related to this issue with the 13.04 Unity version... I've tried this solution, with no result. Please note that this isn't a Xampp question, the same happened to me when I tried to install Skype. UPDATE: I've tried this solution: cd ~/Downloads chmod +x myfile.run sudo sh myfile.run And I've got this error: Syntax error: "(" unexpected What should I do? Thanks!

  • Ubuntu perfomance issues

    - by Pelda
    I have as deafult Win 7 64b. But i get annoyed by some windows stuff so I decided to install ubuntu and learn Linux, because Win 8 is a nightmare. I have my Ubuntu 12.04 64bit installed in 100gb partition of my 1 Tb disc. My problem is that my Ubuntu feel really slower than Win 7 - even though my Win 7 are after some years of usage and they became much slower. And Ubuntu is just installed OS - I just downloaded wine and skype. It takes some time for new window to appear (its not 10 seconds, but its really slower than my windows). Sometimes my donwload get stuck (in basic ubuntu app store) Its just weird to me. I thought its because of some drivers, but I am really new to linux, so I decided to ask some1 before I screw whole system up. Specs: -6gbs of RAM - 3x2gb -3.0 ghz CPU quadcore -graphic card is HD4870 sapphire Please excuse my poor english and my addiction to windows interface. Pelda

  • Opus : le nouveau codec audio open-source est standardisé, il ferait mieux que six codecs propriétaires réunis dixit Mozilla

    Opus : le nouveau codec audio open-source est standardisé Il couvre les usages de six codecs propriétaires et le ferait mieux dixit Mozilla Une victoire historique. Pour Mozilla, la standardisation du codec audio open-source Opus est un évènement de cette envergure. La Fondation y voit « le début de la fin des formats propriétaires [dans l'audio] ». Ce projet de standardisation a été mené à bien grâce à une collaboration entre le monde open-source (dont est issue la Fondation) et des entreprises privées dont Microsoft (au travers de Skype) ou Google. Cette standardisation devrait permettre à Opus de mieux s'imposer que ses prédécesseurs (comme Vorbis)...

  • Apple reveals the iPhone 4.0 multitasking

    Finally Apple decided to add multitasking to the iPhone to compete with all the new devices coming up and existing. At an Apple press event, CEO Steve Jobs announces multitasking support in the newest iPhone operating system. Users will finally be able to switch back and forth between applications like Pandora and Skype without having to shut down the app entirely to enter a new one. Their excuse to not bringing multitasking until now is they were waiting to make multitasking right.

  • Microsoft Launches Outlook.com

    Microsoft announced the news in its Outlook blog, calling the new service modern email for the next billion mailboxes. The company is touting a fresh, clean user interface with fewer pixels in the header and no display ads; it should work well on portable devices. Another key point: it uses Exchange ActiveSync to synchronize your mail, calendar and social experience across your smartphone, tablet and desktop computer. Perhaps the biggest advance, though, is that Microsoft is connecting the email service to Facebook, Twitter, LinkedIn, Google; Skype will be part of this list, too, though i...

  • Synchronizing Mysql Table Schema [on hold]

    - by user1122069
    I have some difficulty keeping track of my SQL changes in a text file in SVN. One solution that I am aware of is to put the SQL queries in files (1.sql, 2.sql...) and to manually load each file at the proper time. Besides missing commas, the process is too cumbersome when builds become more frequent. I have actually taken to asking a co-worker to send me his SQL changes on Skype and we just apply the changes immediately on our local, development, and production servers (using three PhpMyAdmin tabs). I have seen several GUI tools mentioned in similar questions on SO, but these are actually more work and less automated than the aforementioned methods. Is there any standardized process by which this is done in an automated way? I can only guess that large companies build their own mechanisms of keeping track of database schema changes (yet I can't find a word about it - maybe they use files?). This question was closed as off-topic on Stack Overflow, so I am re-posting it here.

  • What videoconferencing platforms work best for distributed software development teams?

    - by user11347
    Today I had a religious experience: I participated in a videoconference using a high quality Polycom system. This made a huge difference in communication quality -- people that I had a terrible time understanding previously now sounded like Shakespeare. Seeing a high quality video image was enormously helpful. I asked operations how much the Polycom cost and they said that it cost $20K new and $4K off eBay. So this solution doesn't work for people who work from home or who work in offices but are in groups of 3 or fewer people. My budget for a videoconferencing system is a few hundred dollars per person. Skype is not nearly good enough. And I haven't seen a consumer webcam that is good enough either. Does such a solution exist? I'm looking to collaborate both with people who are close by (in the same city but not in the same room) and far away (on different continents).

  • How can I add a custom item to the Sound Indicator?

    - by con-f-use
    One of the strength of Unity are the various standardized indicators. I want to customize the sound indicator with an additional menu entry that runs a small shell script. I'm not afraid of a little Python code and I hope someone can point me to the right subroutine in the right file. I suspect that will be fairly easy but all the indicators are just so bloated that I can't look through their code in a reasonable time. Any help is appreciated. I know it is possible as the marvelous Skype-Wrapper does it.

  • Opening programs very slow on ubuntu 12.10

    - by Mislav Blaževic
    When I open any program for first time after boot, it loads VERY slowly (Doesn't matter how long after boot). For example, terminal takes 2-3 seconds, skype and firefox often take much longer. If I close it and open again, it loads in reasonable time (<1 second). I got Intel Core i5-2500K CPU @ 3.30GHz, so it shouldn't be hardware issue... What is causing this? Disk benchmark: Average read time: 115.5 MB/s (100 samples) Average write time: 98.7 MB/s (100 samples) Average access time: 11.79 msec (1000 samples)

  • CKEditor createFakeParserElement: writeHtml is not a function

    - by Phil Sturgeon
    I am trying to write a plugin for CKEditor that is basically just a iframe with PHP content. The user browses around, selects the video they want and then they click insert. The problem is that I need to create a "fake element" for this video, as inserting a video directly seems to show up as a Flash object, and we need to make it look a little different. I have copied together some code from the Flash plugin.js (remember this is all undocumented and uncommented) and so far come up with this: function insertFakeElement( html ) { editor = window.parent.instance; var realElement = CKEDITOR.dom.element.createFromHtml( html ); var fakeElement = editor.createFakeParserElement( realElement, 'cke_video', 'object', true ), fakeStyle = fakeElement.attributes.style || ''; var width = realElement.attributes.width, height = realElement.attributes.height; if ( typeof width != 'undefined' ) fakeStyle = fakeElement.attributes.style = fakeStyle + 'width:' + cssifyLength( width ) + ';'; if ( typeof height != 'undefined' ) fakeStyle = fakeElement.attributes.style = fakeStyle + 'height:' + cssifyLength( height ) + ';'; editor.insertHTML(fakeElement.getHtml()); } The line "giving me jip" is: var fakeElement = editor.createFakeParserElement( realElement, 'cke_video', 'object', true ), It errors here saying: l.writeHtml is not a function [Break on this error] if(o)o.addRules(l);}});})();a.editor.p..."',o,'_text" The .js file is minified and I have no idea how the source files all fit together so I can't track down the cause of this error. Does anybody know what I am doing wrong?

  • SimpleXML - "Node no longer exists"

    - by SubZane
    Hi I'm trying to get the video data from this youtube playlist feed and add the interesting data to an array and use that later, but as you can see from the feed some videolinks are "dead" and that results in problems for my code. The error I get is "Node no longer exists" when I try to access $attrs['url']. I've tried for hours to find a way to check if the node exists before I access it but I have no luck. If anyone could help me to either parse the feed some other way with the same result or create a if-node-exists check that works I would be most happy. Thank you in advance $url = 'http://gdata.youtube.com/feeds/api/playlists/18A7E36C33EF4B5D?v=2'; $sxml = simplexml_load_file($url); $i = 0; $videoobj; foreach ($sxml->entry as $entry) { // get nodes in media: namespace for media information $media = $entry->children('http://search.yahoo.com/mrss/'); // get video player URL $attrs = $media->group->player->attributes(); $videoobj[$i]['url'] = $attrs['url']; // get video thumbnail $attrs = $media->group->thumbnail[0]->attributes(); $videoobj[$i]['thumb'] = $attrs['url']; $videoobj[$i]['title'] = $media->group->title; $i++; }

  • ffmpeg(libavcodec). memory leaks in avcodec_encode_video

    - by gavlig
    I'm trying to transcode a video with help of libavcodec. On transcoding big video files(hour or more) i get huge memory leaks in avcodec_encode_video. I have tried to debug it, but with different video files different functions produce leaks, i have got a little bit confused about that :). [Here] (http://stackoverflow.com/questions/4201481/ffmpeg-with-qt-memory-leak) is the same issue that i have, but i have no idea how did that person solve it. QtFFmpegwrapper seems to do the same i do(or i missed something). my method is lower. I took care about aFrame and aPacket outside with av_free and av_free_packet. int Videocut::encode( AVStream *anOutputStream, AVFrame *aFrame, AVPacket *aPacket ) { AVCodecContext *outputCodec = anOutputStream->codec; if (!anOutputStream || !aFrame || !aPacket) { return 1; /* NOTREACHED */ } uint8_t * buffer = (uint8_t *)malloc( sizeof(uint8_t) * _DefaultEncodeBufferSize ); if (NULL == buffer) { return 2; /* NOTREACHED */ } int packetSize = avcodec_encode_video( outputCodec, buffer, _DefaultEncodeBufferSize, aFrame ); if (packetSize < 0) { free(buffer); return 1; /* NOTREACHED */ } aPacket->data = buffer; aPacket->size = packetSize; return 0; }

  • Mathematics for Computer Science Students

    - by Ender
    To cut a long story short, I am a CS student that has received no formal Post-16 Maths education for years. Right now even my Algebra is extremely rusty and I have a couple of months to shape up my skills. I've got a couple of video lectures in my bookmarks, consisting of: Pre-Calculus Algebra Calculus Probability Introduction to Statistics Differential Equations Linear Algebra My aim as of today is to be able to read the CLRS book Introduction to Algorithms and be able to follow the Mathematical notation in that, as well as being able to confidently read and back-up any arguments written in Mathematical notation. Aside from these video lectures, can anyone recommend any good books to help teach someone wishing to go from a low-foundation level to a more advanced level of Mathematics? Just as a note, I've taken a first-year module in Analytical Modelling, so I understand some of the basic concepts of Discrete Mathematics. EDIT: Just a note to those that are looking to learn Linear Algebra using the Video Lectures I have posted up. Peteris Krumins' Blog contains a run-through of these lecture notes as well as his own commentary and lecture notes, an invaluable resource for those looking to follow the lectures too.

  • Fastest PNG decoder for .NET

    - by sboisse
    Our web server needs to process many compositions of large images together before sending the results to web clients. This process is performance critical because the server can receive several thousands of requests per hour. Right now our solution loads PNG files (around 1MB each) from the HD and sends them to the video card so the composition is done on the GPU. We first tried loading our images using the PNG decoder exposed by the XNA API. We saw the performance was not too good. To understand if the problem was loading from the HD or the decoding of the PNG, we modified that by loading the file in a memory stream, and then sending that memory stream to the .NET PNG decoder. The difference of performance using XNA or using System.Windows.Media.Imaging.PngBitmapDecoder class is not significant. We roughly get the same levels of performance. Our benchmarks show the following performance results: Load images from disk: 37.76ms 1% Decode PNGs: 2816.97ms 77% Load images on Video Hardware: 196.67ms 5% Composition: 87.80ms 2% Get composition result from Video Hardware: 166.21ms 5% Encode to PNG: 318.13ms 9% Store to disk: 3.96ms 0% Clean up: 53.00ms 1% Total: 3680.50ms 100% From these results we see that the slowest parts are when decoding the PNG. So we are wondering if there wouldn't be a PNG decoder we could use that would allow us to reduce the PNG decoding time. We also considered keeping the images uncompressed on the hard disk, but then each image would be 10MB in size instead of 1MB and since there are several tens of thousands of these images stored on the hard disk, it is not possible to store them all without compression.

  • Regular expression either/or not matching everything

    - by dwatransit
    I'm trying to parse an HTTP GET request to determine if the url contains any of a number of file types. If it does, I want to capture the entire request. There is something I don't understand about ORing. The following regular expression only captures part of it, and only if .flv is the first int the list of ORd values. (I've obscured the urls with spaces because Stackoverflow limits hyperlinks) regex: GET.?(.flv)|(.mp4)|(.avi).? test text: GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy match output: GET http: // foo.server.com/download/0/37/3000016511/.flv I don't understand why the .*? at the end of the regex isnt callowing it to capture the entire text. If I get rid of the ORing of file types, then it works. Here is the test code in case my explanation doesn't make sense: public static void main(String[] args) { // TODO Auto-generated method stub String sourcestring = "GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy"; Pattern re = Pattern.compile("GET .?\.flv."); // this works //output: // [0][0] = GET http :// foo.server.com/download/0/37/3000016511/.flv?mt=video/xy // the match from the following ends with the ".flv", not the entire url. // also it only works if .flv is the first of the 3 ORd options //Pattern re = Pattern.compile("GET .?(\.flv)|(\.mp4)|(\.avi).?"); // output: //[0][0] = GET http: // foo.server.com/download/0/37/3000016511/.flv // [0][1] = .flv // [0][2] = null // [0][3] = null Matcher m = re.matcher(sourcestring); int mIdx = 0; while (m.find()){ for( int groupIdx = 0; groupIdx < m.groupCount()+1; groupIdx++ ){ System.out.println( "[" + mIdx + "][" + groupIdx + "] = " + m.group(groupIdx)); } mIdx++; } } }

  • How to get a fully transparent backbuffer in directx 9 without vista Desktop Window Manager

    - by flawlesslyfaulted
    I currently have an activex control that initiates a media (video/audio) framework another development group in my company developed and I am providing a window handle to that code. That handle is being used by their rendering plugin in the pipeline that uses Direct3d for rendering the video using that handle. I have seperate LPDIRECT3D9EX and LPDIRECT3DDEVICE9EX pointers that I initialize in my activex control. I am trying to clear a backbuffer to transparent and then use directx drawing primatives to draw on that backbuffer producing a transparent window with my drawing primatives over the streaming video on the directx surface below. It appears that clearing a device backbuffer with full alpha transparency is ignored by directx. d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_RGBA(0, 0, 1, 0 /*full alpha*/), 1.0f, 0); I can see the object I draw but they are drawn on top of a backbuffer that has the RGB color specified without the alpha value. The project linked (http://www.codeproject.com/KB/directx/umvistad3d.aspx) to in the stackoverflow question below does what I want but requires vista's Desktop Window Manager and won't work for XP. http://stackoverflow.com/questions/148275/how-do-i-draw-transparent-directx-content-in-a-transparent-window I have tried with D3DRS_ALPHABLENDENABLE true with configured blend with no avail. I have also tried to have pixels with full alpha values not rendered using D3DRS_ALPHATESTENABLE, D3DRS_ALPHAREF, and D3DRS_ALPHAFUNC setup but this doesn't work either. I have tried using ColorFill with alpha after retrieving the backbuffer with GetBackBuffer but this doesn't work either. (again only RGB is used) Finally I have tried creating a texture, selecting a surface, colorfilling that surface with a fully transparent alpha value, then loading that surface onto the backbuffer but only the RGB values appear to be used. I have checked the capabilities using the DXCapsViewer.exe and the D3DFMT_A8R8G8B8 backbuffer format that I am using for the backbuffer is valid so it can't be that. Has anyone gotten a transparent backbuffer in directx to work in XP?

  • regex split and extract multiple parts from a string

    - by nLL
    I am trying to extract some parts of the "Video:" line from below text. Seems stream 0 codec frame rate differs from container frame rate: 30000.00 (300 00/1) -> 14.93 (1000/67) Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'C:\a.3gp': Metadata: major_brand : 3gp5 minor_version : 0 compatible_brands: 3gp5isom Duration: 00:00:45.82, start: 0.000000, bitrate: 357 kb/s Stream #0.0(und): Video: mpeg4, yuv420p, 352x276 [PAR 1:1 DAR 88:69], 344 kb /s, 14.93 fps, 14.93 tbr, 90k tbn, 30k tbc Stream #0.1(und): Audio: aac, 16000 Hz, mono, s16, 11 kb/s Stream #0.2(und): Data: mp4s / 0x7334706D, 0 kb/s Stream #0.3(und): Data: mp4s / 0x7334706D, 0 kb/s* This is an output from ffmpeg command line where i can get Video: part with private string ExtractVideoFormat(string rawInfo) { string v = string.Empty; Regex re = new Regex("[V|v]ideo:.*", RegexOptions.Compiled); Match m = re.Match(rawInfo); if (m.Success) { v = m.Value; } return v; } and result is mpeg4, yuv420p, 352x276 [PAR 1:1 DAR 88:69], 344 kb What i am trying to do is to somehow split that line and get mpeg4 yuv420p 352x276 [PAR 1:1 DAR 88:69] 344 kb assigned to different string objects instead of single

  • Anchor HTML DIV tag to right of screen

    - by Phillip
    Hello, I have a site that has 2 DIV tags, one floats left the other floats right. The left DIV contains text for the page, the other DIV is used to display a video. When I have text in the left DIV that fits the entire width of the screen the video shows up where I want it. However, a few pages have very little text and cause the video to show up in the right-center of the screen. I want to anchor this DIV to the right of the screen regardless of how much text is shown. I don't seem to get this problem in lower resolutions, it occurs more in the higher resolutions (such as 1280x1024). You can see an example on these pages: http://www.quilnet.com/TechSupport.aspx - Positions the right DIV where I want it regardless of the resolution. http://www.quilnet.com/ContactUs.aspx - Makes the right DIV closer to the center in higher resolutions. I want it in the position of the page TechSupport.aspx. I am trying to refrain from using the width parameter because I want it to be resolutionally compliant. I don't want my viewers to have to move a scroll bar left and right. Any ideas? Thanks!

  • Add a child inside a newly created instance, inside of a loop in AS3

    - by HeroicNate
    I am trying to create a gallery where each thumb is housed inside of it's own movie clip that will have more data, but it keeps failing because it won't let me refer to the newly created instance of the movie clip. Below is what I am trying to do. var xml:XML; var xmlReq:URLRequest = new URLRequest("xml.xml"); var xmlLoader:URLLoader = new URLLoader(); var imageLoader:Loader; var vidThumbn:ThumbNail; var next_y:Number = 0; for(var i:int = 0; i < xml.downloads.videos.video.length(); i++) { vidThumbn = new ThumbNail(); imageLoader = new Loader(); imageLoader.load(new URLRequest(xml.downloads.videos.video[i].ThumbnailImage)); vidThumbn.y = next_y; vidThumbn.x = 0; next_y += 117; imageLoader.name = xml.downloads.videos.video[i].Files[0].File.URL; videoBox.thumbList.thumbListHolder.addChild(vidThumbn); videoBox.thumbList.thumbListHolder.vidThumbn.addChild(imageLoader); } It dies every time on that last line. How do I refer to that vidThumbn instance so I can add the imageLoader? I don't know what I'm missing. It feels like it should work.
