  • winsock receiving incoming data slower than expected.

    - by k80sg
    Hi folks, I have a sender machine which sends bytearray data to my prog at an interval of about 5 miliseconds/per msg, about 6 - 7 bytearray messages per seconds that is. The problem is that the winsock in my program doesn't seem to receive these bytearray fast enough. For every 10 messages sent over, I am only able to receive about 6 to 7. Any advices? Thanks.

  • How does an open source project get funded?

    - by squillman
    Other than large entities sponsoring a project, such as the Apache foundation, what are other ways that full-time open source developers (specifically those on products offered free of charge) receive funding for their projects? Obviously there will be donations that will trickle in but from what other channels do developers receive more steady income?

  • How do I hook a git pull on the remote?

    - by Danny
    Is there a way to hook when a git pull happens on the remote (similar to a pre-receive or post-receive). Basically I'd like to be able to cause the remote to commit whatever it has when there is a pull. In my situation, whatever is live on the remote is an authoritative source which may get modified without a git commit. I want to make sure when I pull I'm always able to get the latest of whatever is live.

  • Intercepting touch events on activity and button on Android

    - by hgpc
    I have an Android activity with an ImageButton. I would like to execute some logic when the button is clicked and show a different image for the pressed state, but also receive the touch event on the activity. By default only the button receives the touch event. If I set the clickable attribute of the button to false then only the activity receives the touch event. What's the best way to receive the touch event in both the activity and the button?

  • SMS to server service

    - by duckofrubber
    Hi, I need to find a service that will allow me to send and receive SMS on a server for a project. The project requires that a user will have up to 8 keyword options to send, and will receive a different response back based on the keyword that they enter. Does anyone know of services that I could look into that will allow this? Thanks.

  • Use one Socket to send and recieve data

    - by volody
    What makes more sense? use one socket to send and receive data to/from a embedded hardware device use one socket to send data and separate socket to read data Communication is not very intensive but the important point is to receive data as fast as possible. On application side is used Windows XP and up.

  • XmlSerializer.Deserialize blocks over NetworkStream

    - by Luca
    I'm trying to sends XML serializable objects over a network stream. I've already used this on an UDP broadcast server, where it receive UDP messages from the local network. Here a snippet of the server side: while (mServiceStopFlag == false) { if (mSocket.Available > 0) { IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Any, DiscoveryPort); byte[] bData; // Receive discovery message bData = mSocket.Receive(ref ipEndPoint); // Handle discovery message HandleDiscoveryMessage(ipEndPoint.Address, bData); ... Instead this is the client side: IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Broadcast, DiscoveryPort); MemoryStream mStream = new MemoryStream(); byte[] bData; // Create broadcast UDP server mSocket = new UdpClient(); mSocket.EnableBroadcast = true; // Create datagram data foreach (NetService s in ctx.Services) XmlHelper.SerializeClass<NetService>(mStream, s); bData = mStream.GetBuffer(); // Notify the services while (mServiceStopFlag == false) { mSocket.Send(bData, (int)mStream.Length, ipEndPoint); Thread.Sleep(DefaultServiceLatency); } It works very fine. But now i'me trying to get the same result, but on a TcpClient socket, but the using directly an XMLSerializer instance: On server side: TcpClient sSocket = k.Key; ServiceContext sContext = k.Value; Message msg = new Message(); while (sSocket.Connected == true) { if (sSocket.Available > 0) { StreamReader tr = new StreamReader(sSocket.GetStream()); msg = (Message)mXmlSerialize.Deserialize(tr); // Handle message msg = sContext.Handler(msg); // Reply with another message if (msg != null) mXmlSerialize.Serialize(sSocket.GetStream(), msg); } else Thread.Sleep(40); } And on client side: NetworkStream mSocketStream; Message rMessage; // Network stream mSocketStream = mSocket.GetStream(); // Send the message mXmlSerialize.Serialize(mSocketStream, msg); // Receive the answer rMessage = (Message)mXmlSerialize.Deserialize(mSocketStream); return (rMessage); The data is sent (Available property is greater then 0), but the method XmlSerialize.Deserialize (which should deserialize the Message class) blocks. What am I missing?

    - by Eric Di Bari
    I am the technology director at a small nonprofit, and we are in the process of making a new website. We have several proposed mock-ups of different homepage designs, and need to receive input from our board members. Is there an online application/program/framework that will receive and organize user comments? I'm looking for something that will allow commenting while viewing the page, rather than just a message board or wiki.

  • netServiceBrowserDidStopSearch not called

    - by user263569
    I'm now writing a Bonjour service listener class, according to the document here: Currently, it seems working, I can receive "netServiceBrowserWillSearch:" and "didFindService:moreComing:" correctly. However, after a long wait, I cannot receive " netServiceBrowserDidStopSearch:" or "netServiceBrowser:didNotSearch:". Therefore I don't know that is the proper time for my delegate class to stop showing some UI. Could anyone have an idea for this? Thanks.

  • Active Directory Time Synchronisation - Time-Service Event ID 50

    - by George
    I have an Active Directory domain with two DCs. The first DC in the forest/domain is Server 2012, the second is 2008 R2. The first DC holds the PDC Emulator role. I sporadically receive a warning from the Time-Service source, event ID 50: The time service detected a time difference of greater than %1 milliseconds for %2 seconds. The time difference might be caused by synchronization with low-accuracy time sources or by suboptimal network conditions. The time service is no longer synchronized and cannot provide the time to other clients or update the system clock. When a valid time stamp is received from a time service provider, the time service will correct itself. Time sync in the domain is configured with the second DC to synchronise using the /syncfromflags:DOMHIER flag. The first DC is configured to sync time using a /syncfromflags:MANUAL /reliable:YES, from a peerlist consisting of a number of UK based stratum 2 servers, such as ntp2d.mcc.ac.uk. I'm confused why I receive this event warning. It implies that my PDC emulator cannot synchronise time with a supposedly reliable external time source, and it quotes a time difference of 5 seconds for 900 seconds. It's worth also mentioning that I used to use a UK pool from ntp.org but I would receive the warning much more often. Since updating to a number of UK based academic time servers, it seems to be more reliable. Can someone with more experience shed some light on this - perhaps it is purely transient? Should I disregard the warning? Is my configuration sound? EDIT: I should add that the DCs are virtual, and installed on two separate VMware ESXi/vSphere physical hosts. I can also confirm that as per MDMarra's comment and best practice, VMware timesync is disabled, since: c:\Program Files\VMware\VMware Tools\VMwareToolboxCmd.exe timesync status returns Disabled. EDIT 2 Some strange new issue has cropped up. I've noticed a pattern. Originally, the event ID 50 warnings would occur at about 1230pm each day. This is interesting since our veeam backup happens at 12 midday. Since I made the changes discussed here, I now receive an event ID 51 instead of 50. The new warning says that: The time sample received from peer server.ac.uk differs from the local time by -40 seconds (Or approximately 40 seconds). This has happened two days in a row. Now I'm even more confused. Obviously the time never updates until I manually intervene. The issue seems to be related to virtualisation and veeam. Something may be occuring when veeam is backing up the PDCe. Any suggestions? UPDATE & SUMMARY msemack's excellent list of resources below (the accepted answer) provided enough information to correctly configure the time service in the domain. This should be the first port of call for any future people looking to verify their configuration. The final "40 second jump" issue I have resolved (there are no more warnings) through adjusting the VMware time sync settings as noted in the veeam knowledge base article here: http://www.veeam.com/kb1202 In any case, should any future reader use ESXi, veeam or not, the resources here are an excellent source of information on the time sync topic and msemack's answer is particularly invaluable.

  • How to install Oracle Weblogic Server using OS-specific Package installer?(Linux/Solaris)

    - by PratikS -- Oracle
    Note: OS-specific Package installer As the name suggests the installer is platform specific. It is meant for installation with a 32bit JVM only. Both SUN and JROCKIT 32 bit JDKs come bundled with "OS-specific Package installer", so no need to install the JDK in advance. There are three different ways of installing Oracle Weblogic Server: Graphical mode Console mode Silent mode For Linux/Solaris: Steps to install OS-specific Package .bin installer(for Linux/Solaris) are almost same as windows except for the way we launch the installation.Installer: wls_<version>_<linux/solaris>32.bin (E.g. wls1036_linux32.bin/wls1036_solaris32.bin) 1) Graphical mode: Log in to the target UNIX system. Go to the directory that contains the installation program.(Make sure GUI is enabled or else it will default to console mode) Launch the installation by entering the following commands: [weblogic@pratik ~]$ pwd/home/oracle[weblogic@pratik ~]$ cd WLSInstallers/[weblogic@pratik WLSInstallers]$ ls -ltrtotal 851512-rw-rw-r-- 1 oracle oracle 871091023 Dec 22  2011 wls1036_linux32.bin[weblogic@pratik WLSInstallers]$ chmod a+x wls1036_linux32.bin[weblogic@pratik WLSInstallers]$ ls -ltrtotal 851512-rwxrwxr-x 1 oracle oracle 871091023 Dec 22  2011 wls1036_linux32.bin[weblogic@pratik WLSInstallers]$ ./wls1036_linux32.bin As soon as you run ./wls1036_linux32.bin with GUI enabled you would see the following screen: Rest of the screens and steps are similar to that of Graphical mode installation on windows, refer: How to install Oracle Weblogic Server using OS-specific Package installer?(Windows) 2) Console mode: Log in to the target UNIX system.
