  • 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)...

  • Why does the the Java VM not recover after "Too many open files" errors?

    - by Michael
    In certain well-understood circumstances, our application will open too many sockets (database connections) and reach the maximum open files that the OS allows. We understand this; we are fixing the issue and also bumping up the limit. What we can't explain is why parts of our application don't recover even after the number of connections abates and we're well within the limit. In this case, it's an application running under Tomcat. When this happens, we first start seeing "Too many open files" errors: SEVERE: Socket accept failed java.net.SocketException: Too many open files at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390) at java.net.ServerSocket.implAccept(ServerSocket.java:453) at java.net.ServerSocket.accept(ServerSocket.java:421) at org.apache.tomcat.util.net.DefaultServerSocketFactory.acceptSocket(DefaultServerSocketFactory.java:61) at org.apache.tomcat.util.net.JIoEndpoint$Acceptor.run(JIoEndpoint.java:310) at java.lang.Thread.run(Thread.java:619) Eventually, we start seeing NoClassDefFoundErrors inside an application thread that's trying to open HTTP connections: java.lang.NoClassDefFoundError: org/apache/commons/httpclient/protocol/ControllerThreadSocketFactory at org.apache.commons.httpclient.protocol.DefaultProtocolSocketFactory.createSocket(DefaultProtocolSocketFactory.java:128) at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:707) at org.apache.commons.httpclient.MultiThreadedHttpConnectionManager$HttpConnectionAdapter.open(MultiThreadedHttpConnectionManager.java:1349) [...] Caused by: java.lang.ClassNotFoundException: org.apache.commons.httpclient.protocol.ControllerThreadSocketFactory at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) ... 8 more When the errant connections go away, the server starts accepting connections again, and everything seems ok, but we're left with the latter error constantly being spewed to stderr. Although the application typically logs unloaded classes to stdout, I don't see any such logs just before, during or after the "Too many open files" errors. My initial theory was that the Hotspot JVM would unload seemingly unused classes when it encounters "Too many open files," but if so, it doesn't log the fact. I'd also expect it to recover if that were the case. Platform details: Java(TM) SE Runtime Environment (build 1.6.0_14-b08) Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode) Apache Tomcat Version 6.0.18

  • Base 128 or 256 Encoding for the Binary Lexical Octet Adhoc Transport Protocol?

    - by Randolpho
    I'm in the process of implementing a network driver for the Binary Lexical Octet Adhoc Transport (BLOAT) protocols in the hopes of replacing the TCP/UDP/IP stack with a much more flexible XML structure. BLOAT is detailed in RFC 3252, so if you're unfamiliar with the protocol I highly recommend you read the entire RFC before providing any comments. Don't worry, it's short and sweet; you might even enjoy it. Anyway, my problem is this: BLOAT requires that the payload be Base64 encoded which doesn't make sense to me. I mean, sure, it's the internet standard for binary payloads, but there are better, more efficient encodings available: Base128 and Base256, for example. That the RFC requires Base64 and doesn't allow for any other payload encoding really bothers me. To that end, I'm considering a small optional change to the protocol. Embrace and extend, right? Anyway, I'd like to modify the payload element to accept an encoding attribute, which can extend the encoding to Base128 or Base256, or even to other encodings I can't conceive of at the moment. If the encoding attribute isn't present, Base64 would be assumed. So my question is this: should I? I mean, BLOAT is an accepted standard, even if it isn't exactly omnipresent. If I make this change, will there be compatibility issues? I don't foresee any, but perhaps you, oh great Stack Overflow Community, can? If I do implement this change, should I contact the original RFC author? Should I offer a supplemental RFC?

  • How do I create a *public* Facebook community page using the Open Graph protocol?

    - by jmbledsoe
    I am trying to integrate pages from a site I am building into the Facebook Open Graph. My goal is to create a Facebook "Community Page" for each cause in my application. I have added Open Graph tags to a page so that I can Like it in Facebook, and a community page corresponding to my cause has been added to Facebook. However, I am the only one who can see the community page, since I am its administrator. All other users are redirected to the URL of the cause itself. My community page is at: http://www.facebook.com/pages/Kings-Hospital-Garden-Short-Term-Aid/123353527700762 When fans go to this page, I would like them to see the Facebook community page rather than being redirected. In other words, I want my community page to behave like the following community page referenced in all of the Facebook documentation on the subject: http://www.facebook.com/pages/The-Rock/109550739071923 Any insight into this would be greatly appreciated. Also, I asked this same question on the Facebook Platform Developer Forum, but I suspect that the SO community may be more quick to respond.

  • When connecting to a server using the DRDA protocol, is it true that the first Client-To-Server command MUST be EXCSAT chained with ACCSEC?

    - by Alon Rew
    When connecting to a server using the DRDA protocol, is it true that the first Client-To-Server command MUST be EXCSAT chained with ACCSEC? I found 2 different answers when I googled it. If you look at The Open Group web site (https://collaboration.opengroup.org/dbiop/) it can be understood that the answer is NO. However, if you look at the IBM website (http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp?topic=%2Fcom.ibm.ims11.doc.apr%2Fims_ddm_excsat.htm) you can understand the answer is YES. So which is it?

  • How to open the file under cursor in vim when its listing directory contents(Netrw Directory Listing)

    - by balki
    I can press o but it creates a new window and opens the file there. I want it to open in the same window. At least it should display on the same window each time open some file but it creates new windows for each file I open. Also is there a way to make it open as a vertical split and not horizontal split? Where can I find the complete documentation/cheatsheet of all possible commands in 'Netrw Directory Listing' mode?

  • How could I determine which SMB client/session has a specific file open on a Server 2008R2 Windows file server?

    - by Rasmir
    What I need a way to associate a client name or IP address with an open file, so that I can cleanly close the file for maintenance. NET SESSION doesn't show the names of open files and NET FILE doesn't show the client which has the file open. I had hoped that I could cross-reference the data from these two commands, but that doesn't seem doable. Everything else I've see provides the same data as these commands, with no apparent way to determine which client machine has the file open.

  • Open File Dialog MVVM

    - by Jose
    Ok I really would like to know how expert MVVM developers handle an openfile dialog in WPF. I don't really want to do this in my ViewModel(where 'Browse' is referenced via a DelegateCommand) void Browse(object param) { //Add code here OpenFileDialog d = new OpenFileDialog(); if (d.ShowDialog() == true) { //Do stuff } } Because I believe that goes against MVVM methodology. What do I do?

  • IE8 Developer Tools won't open

    - by Dave
    Just installed IE8 on WinXP. Trying to use the Dev Tools but, clicking on the menu item or hitting F12 doesn't do anything. I can see the option in the tools menu, just can't use it. I've checked to make sure it wasn't opening minimized or off screen and I've checked the registry settings used to disable them. Those registry keys don't even exists. Suggestions? I was going to reinstall, but, thought I'd check here first.

  • fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-gd-1_43.lib'

    Made a new project, added main.cpp and wrote the code at this URL: http://www.boost.org/doc/libs/1_43_0/doc/html/boost_asio/example/echo/async_tcp_echo_server.cpp Also, added the appropriate include path. What's next?!?!! It seems like a darn mystery to build a boost code! Been digging on it for more than 10 hours. Can anyone give a straightforward answer on how to build the boost library from the code under windows, VC9? God bless you all.

  • How to use jxl open file turn off gridlines and save

    - by sally
    I am new to jxl, but I have what I think is a pretty simple requirement. I want to take an existing .xls file with three tabs, turn off the gridlines on all 3, and then save it again. It looks from the API like there is a function to handle gridlines setPrintGridLines(boolean b) I would love it if someone could give me sample code - or a link pointing me in the right direction - on how to do this. Thank you in advance Here is what I've tried (bear with me, like I said I'm brand new to jxl) WorkbookSettings ws = new WorkbookSettings(); WritableWorkbook workbook = Workbook.createWorkbook(new File(xlsFile), ws); WritableSheet[] w = workbook.getSheets(); for ( WritableSheet sheet : w ) { sheet.getSettings().setPrintGridLines(false); } workbook.write(); workbook.close(); I get the error Could not generate XLS. Index: 0, Size: 0 but I may be totally off base in what I am trying

  • Losing sessions with window.open and cakephp redirection in PHP with cakephp

    - by vsecades
    Hi guys, Ok, here goes a very strange problem... Our team is using cakephp to develop a large application. Everything session related is working properly so far. The only issues we've had so far are related to iframes and opening windows in other subdomains. I'll explain: User opens up site A and logs into it, creation a User in a session. Cookies are set, everything works as expected. The user clicks a link that opens up Site B via Javascript. When they go to that site, they are automatically logged in by a backend mechanism and infrastructure. Site B is a subdomain of Site A. On that site there is another mechanism to go back to the first page (a link rather) that logs them back in to site A. The fun part about this whole process is the following, and that on step 3, when we click on the link, the session on Site A has been lost. I know it's lost because it is forcing login again. I am a bit lost, as the rest of the application that work with AJAX and uses iframes and stuff works flawlessly, just this one item does not work as one would expect. Any assistance would be appreciated. Cheers, Valentin

But I do not want to make it opne source yet. It is additional affort to clean up the code, documantation and so on... And this is just a small useful tool. Can I use the MIT license in this case, or the MIT license obligates me to distribute the source code? Which license is best in this case? Thanks.

  • Webmail client that can open multiple email addresses at once like a desktop client

    - by Trent
    I've got 5 email domains with multiple email addresses on each domain. Traditional webmail clients only seem to allow you to browse a single account at a time (ie, you log into that account). With over 20 email addresses I need to monitor, this is obviously a major time sink. Is there a (preferably OSS, unix-based) webmail client that simulates a desktop email client, ie I log in once and can access all the email addresses from a central control panel? I've considered using a ticket system but that is overkill and not really used to my needs.

  • YUI Menu rendering below "fold" on first open

    - by Flash84x
    I have a YUI menu on the bottom navigation of the screen which creates a large white space beneath it where the action list would be rendered if visible... On the first click the menu will render in that white space which requires the user to scroll to see it... on the second click however it will draw upward (ideally) so that the user does not have to scroll to see the menu... the second click also kills that block of white space... i found adding a style of display:none to the div kills the white space... but then YUI doesn't set the display to block, which from what I understood it should... so I wrote another method that would do that manually... but the same behavior happens, the menu first renders below the fold requiring the user to scroll.... 2nd time its works fine... some reason the top/left positions are not being calculated properly on the first click and i cannot seem to figure out why
