  • Unity Launcher missing and Terminal shortcut stopped working

    - by Diana
    When I restarted my Ubuntu after it being updated, I found the Unity launch bar was gone. I tried looking up several solutions online, blindly typing in the commands that others suggested, and I found after the umpteenth time rebooting after typing in another foreign command, I found I couldn't even open up the terminal with the Ctrl+Alt+t shortcut either and I have no idea how to fix this. This was the last set of instructions I remember following before terminal stopped opening. Install CCSM sudo apt-get install compizconfig-settings-manager And then run it in terminal (Ctrl+Alt+t) ccsm Then search for "Ubuntu Unity Plugin". If it's not checked, check it. If it is checked you may have another issue. Try restarting compiz: kill -9pidof compiz` This will kill it, it should start up again, if it doesn't, CTRL+ALT+F2 and then type: sudo service lightdm restart to restart the window manager. Go back to the terminal and run: unity --reset

  • What happens to an instance of ServerSocket blocked inside accept(), when I drop all references to i

    - by Hanno Fietz
    In a multithreaded Java application, I just tracked down a strange-looking bug, realizing that what seemed to be happening was this: one of my objects was storing a reference to an instance of ServerSocket on startup, one thread would, in its main loop in run(), call accept() on the socket while the socket was still waiting for a connection, another thread would try to restart the component under some conditions, the restart process missed the cleanup sequence before it reached the initialization sequence as a result, the reference to the socket was overwritten with a new instance, which then wasn't able to bind() anymore the socket which was blocking inside the accept() wasn't accessible anymore, leaving a complete shutdown and restart of the application as the only way to get rid of it. Which leaves me wondering: with no references left to the ServerSocket instance, what would free the socket for a new connection? At what point would the ServerSocket become garbage collected? In general, what are good practices I can follow to avoid this type of bug?

  • Can I use the decorator pattern to wrap a method body?

    - by mgroves
    I have a bunch of methods with varying signatures. These methods interact with a fragile data connection, so we often use a helper class to perform retries/reconnects, etc. Like so: MyHelper.PerformCall( () => { doStuffWithData(parameters...) }); And this works fine, but it can make the code a little cluttery. What I would prefer to do is decorate the methods that interact with the data connection like so: [InteractsWithData] protected string doStuffWithData(parameters...) { // do stuff... } And then essentially, whenever doStuffWithData is called, the body of that method would be passed in as an Action to MyHelper.PerformCall(). How do I do this?

  • Problem installing NVIDIA-Linux-x86-302.07.run in 12.04

    - by paj100
    I have a catch 22 problem in trying to install this driver (NVIDIA-Linux-x86-302.07.run) to set my screen to its native resolution of 1280x1024 (hpL1906). Problem is that in order to install this driver, I need to stop the XServer but when I do this (sudo service lightdm stop), my screen goes blank and displays the message - Out of Range 1280X1024 need to reset (or something similar) - and I can go no further. So, I cannot install NVIDIA-Linux-x86-302.07.run without stopping lightdm but when I do so, I can no longer see anything on the screen or go further to install the driver that would let me adjust the resolution. Any advice on getting out of this loop would be greatly appreciated.

  • How to know from a bash script if the user abruptly closes ssh session

    - by Figo
    I have a bash script that acts as the default shell for a user loging in trough ssh. It provides a menu with several options one of wich is sending a file using netcat. The netcat of the embedded linux I'm using lacks the -w option, so if the user closes the ssh connection without ever sending the file, the netcat command waits forever. I need to know if the user abruptly closes the connection so the script can kill the netcat command and exit gracefully. Things I've tried so far: Trapping the SIGHUP: it is not issued. The only signal issued i could find is SIGCONT, but I don't think it's reliable and portable. Playing with the -t option of the read command to detect a closed stdin: this would work if not for a silly bug in the embedded read command (only times out on the first invocation)

  • Using Entity Framework 4.0 with Code-First and POCO: How to Get Parent Object with All its Children

    - by SirEel
    I'm new to EF 4.0, so maybe this is an easy question. I've got VS2010 RC and the latest EF CTP. I'm trying to implement the "Foreign Keys" code-first example on the EF Team's Design Blog, http://blogs.msdn.com/efdesign/archive/2009/10/12/code-only-further-enhancements.aspx. public class Customer { public int Id { get; set; public string CustomerDescription { get; set; public IList<PurchaseOrder> PurchaseOrders { get; set; } } public class PurchaseOrder { public int Id { get; set; } public int CustomerId { get; set; } public Customer Customer { get; set; } public DateTime DateReceived { get; set; } } public class MyContext : ObjectContext { public RepositoryContext(EntityConnection connection) : base(connection){} public IObjectSet<Customer> Customers { get {return base.CreateObjectSet<Customer>();} } } I use a ContextBuilder to configure MyContext: { var builder = new ContextBuilder<MyContext>(); var customerConfig = _builder.Entity<Customer>(); customerConfig.Property(c => c.Id).IsIdentity(); var poConfig = _builder.Entity<PurchaseOrder>(); poConfig.Property(po => po.Id).IsIdentity(); poConfig.Relationship(po => po.Customer) .FromProperty(c => c.PurchaseOrders) .HasConstraint((po, c) => po.CustomerId == c.Id); ... } This works correctly when I'm adding new Customers, but not when I try to retrieve existing Customers. This code successfully saves a new Customer and all its child PurchaseOrders: using (var context = builder.Create(connection)) { context.Customers.AddObject(customer); context.SaveChanges(); } But this code only retrieves Customer objects; their PurchaseOrders lists are always empty. using (var context = _builder.Create(_conn)) { var customers = context.Customers.ToList(); } What else do I need to do to the ContextBuilder to make MyContext always retrieve all the PurchaseOrders with each Customer?

  • Accessing cookies in php which are set in java web application

    - by user866937
    I am setting a cookie at the domain level on encrypted connection in Java web application running on tomcat and I would like it to be accessible in a php web application running on a same domain but different subdomain. Java web application running on https://javaapp.mycompany.com php web application running on https://phpapp.mycompany.com/subpath/index.php From java, I am setting the cookie with following parameters: Domain: .mycompany.com Send For: Encrypted connections only Expires: After 2 months Path: /subpath Name: __C Value: 1 Dumping all the cookies from my php web application running on https, I do not see any cookies getting dumped by the php web application. Whereas if I set the cookies in Java for any type of connection, only then php web application is able to see them if I run the php app on http instead of https. I believe php web app should be able to retrieve then cookies set for https only and for particular domain and all immediate sub-domains. What am I doing wrong here? Thanks in advance for the help.

  • Redirecting before POST upload has been completed

    - by vartec
    I have form with file upload. The files to be uploaded actually are pictures and videos, so they can be quite big. I have logic which based on headers and first 1KB can determine if the rest will be processed or immediately rejected. In the later case I'd like to redirect client to error page without having to wait for upload to finish. The case is, that just sending response before POST is complete doesn't seem to work. The redirect get's ignored and if I close connection, browser complains with "Connection reset by peer" error. So the question is: is it even possible to do that in pure HTTP (without JavaScript on client-side), and if so, how?

  • Is the "message" of an exception culturally independent?

    - by Ray Hayes
    In an application I'm developing, I have the need to handle a socket-timeout differently from a general socket exception. The problem is that many different issues result in a SocketException and I need to know what the cause was. There is no inner exception reported, so the only information I have to work with is the message: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond" This question has a general and specific part: is it acceptable to write conditional logic based upon the textual representation of an exception? Is there a way to avoid needing exception handling? Example code below... try { IPEndPoint endPoint = null; client.Client.ReceiveTimeout = 1000; bytes = client.Receive(ref endPoint); } catch( SocketException se ) { if ( se.Message.Contains("did not properly respond after a period of time") ) { // Handle timeout differently.. } }

  • C# connectionString encryption questions

    - by 5YrsLaterDBA
    I am learning how to encrypt the ConnectionString for our C# (3.5) Application. I read the .Net Framwork Developer Guide (http://msdn.microsoft.com/en-us/library/89211k9b(VS.80).aspx) about securing connection string. but not fully understand the contents. It says "The connection string can only be decrypted on the computer on which it was encrypted." We have a release machine which will build our application which will generate the OurApp.exe.config and then install it to many product machines. Is that meam we have to have this encryption process separated with our application and run it at individual product machine? We may use the "RSAProtectedConfigurationProvider". It mentioned we need encryption key for that provider. when and how we should provide the encryption key? thanks,

  • return statement from within using

    - by Bob
    using (IDbCommand command = new SqlCommand()) { IDbDataAdapter adapter = new SqlDataAdapter(); DataSet ds = new DataSet(); adapter.SelectCommand = command; command.Connection = _dataAccess.Connection; command.CommandType = CommandType.StoredProcedure; command.CommandText = "GetProcData"; command.Parameters.Add(new SqlParameter("@ProcID ", procId)); adapter.Fill(ds); return ds.Tables[0].AsEnumerable(); } This returns an IEnumerable DataRow The question is that since the return is within the using statement, will it property dispose of the IDBCommand? I know I can easily refactor this so I change the scope of the DataSet outside of the using, but it is more of a wonder than anything else.

  • Network programming on java

    - by maks
    I have written a simple network program on java using sockets. Program has a client and a server. When user types a word on client side, server simply return this word to client. On server side I use Serversocket and bind it to port 4444. Why does not firewall block this connection on my server PC? I ask this question because earlier I wrote this program using corba technology, and firewall on my server PC was blocking the connection to this port; when I disabled the firewall the program worked fine.

  • How to enable an AdventureWorks database in a web application?

    - by salvationishere
    I am developing a C#/SQL ASP.NET web application in VS 2008. I want the users to be able to select an Adventureworks table and then an input file. The user is then able to map columns from the file with the selected table. This app works fine now in VS. But when I Browse in IIS, it doesn't show any of the tables. I think this is because currently Adventureworks connection string is integrated security (Windows authentication). If I want users to be able to select a table, do I have to change connection to SQL Server authentication? And if so, is the only way to do this to reinstall SQL Server? Or can I just reinstall Adventureworks? And if I reinstall SQL Server, do I need to reinstall VS also for this to work? This could be painful...

  • A script that writes errors and should create a event-error

    - by helmich
    this if it works should check the internet connection if there is a connection it does nothing. if there isn't a connection it should write a error in a txtfile if that happend 5 times it should create a error but it doesn't I will show you the whole code that i have now and the piece of code that i want in a loop. I can't get it in the way i want. I want it to creat 1 Event-error after 5 times writing to the file. this is the whole code i will put the code i want in a loop under it strDirectory = "Z:\text2" strFile = "\foutmelding.txt" strText = "De connectie is verbroken" strWebsite = "www.helmichbeens.com" If PingSite(strWebsite) Then WScript.Quit 'Website is pingable - no further action required Set objFSO = CreateObject("Scripting.FileSystemObject") RecordSingleEvent Dim fout For fout = 1 To 5 : Do If fout = 5 Then Exit Do Set WshShell = WScript.CreateObject("WScript.Shell") Call WshShell.LogEvent(1, "Test Event") Loop While False : next '------------------------------------ 'Record a single event in a text file '------------------------------------ Sub RecordSingleEvent If Not objFSO.FolderExists(strDirectory) Then objFSO.CreateFolder(strDirectory) Set objTextFile = objFSO.OpenTextFile(strDirectory & strFile, 8, True) objTextFile.WriteLine(Now & strText) objTextFile.Close End sub '---------------- 'Ping my web site '---------------- Function PingSite( myWebsite ) Set objHTTP = CreateObject( "WinHttp.WinHttpRequest.5.1" ) objHTTP.Open "GET", "http://" & myWebsite & "/", False objHTTP.SetRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MyApp 1.0; Windows NT 5.1)" On Error Resume Next objHTTP.Send PingSite = (objHTTP.Status = 200) On Error Goto 0 End Function '----------------------------------------------- 'Counts the number of lines inside the text file '----------------------------------------------- Function EventCount(fout) strData = objFSO.OpenTextFile(strDirectory & strFile,ForReading).ReadAll arrLines = Split(strData,vbCrLf) EventCount = UBound(arrLines) End Function This is the whole code, and it doesnt work correctly becaus it creats a event-log rightaway and it should do that after the script has written 5 times to the textfile here is the code that writes to a textfile Sub RecordSingleEvent If Not objFSO.FolderExists(strDirectory) Then objFSO.CreateFolder(strDirectory) Set objTextFile = objFSO.OpenTextFile(strDirectory & strFile, 8, True) objTextFile.WriteLine(Now & strText) objTextFile.Close End sub and here is the code but this part doesnt not work or atleast i think it is this part Dim fout For fout = 1 To 5 : Do If fout = 5 Then Exit Do Set WshShell = WScript.CreateObject("WScript.Shell") Call WshShell.LogEvent(1, "Test Event") Loop While False : next Function EventCount(fout) strData = objFSO.OpenTextFile(strDirectory & strFile,ForReading).ReadAll arrLines = Split(strData,vbCrLf) EventCount = UBound(arrLines) End Function this is the not working part and I don't know what to do anymore so can you please take a look at it tank you very much. btw: this code can be very usefull for a network administrator

  • Sorting 1 million 8-digit numbers in 1MB of RAM

    - by Favourite Chigozie Onwuemene
    I have a computer with 1M of RAM and no other local storage. I must use it to accept 1 million 8-digit decimal numbers over a TCP connection, sort them, and then send the sorted list out over another TCP connection. The list of numbers may contain duplicates, which I must not discard. The code will be placed in ROM, so I need not subtract the size of my code from the 1M. I already have code to drive the ethernet port and handle TCP/IP connections, and it requires 2k for its state data, including a 1k buffer via which the code will read and write data. Is there a solution to this problem?

  • Serialized task distribution: use thread or epoll?

    - by hpsmouse
    Now I'm in such a situation that there is a group of predefined tasks for multiple clients to do(any client can take any task). When a client connects to the server, server choose a task from the uncompleted tasks and send it to the client. It takes a while for the client to finish the task and send the result back to the server. Since a task should be sent to only one client, server should process requests in a serialized way. Now I have two plans to do it: create a thread for each client connection and all the threads take turns accessing the task pool, or use epoll listening on all the connection and process for each event of clients. Which one is better for the job? Or is there any other ideas? The server will be run on a multi-core machine.

  • What is the Fastest Java/PHP Bridge?

    - by The Rook
    A bi-directional communication is required between a Java application and a PHP web app. A Fast and low Resource consumption is the number 1 priority in this project There is the PHP/Java Brdige(PJB) project and there are benchmarks to show that is very fast. Do you know of a faster approach? xml over http strikes me as a bit wasteful, but I don't know of a better approach. Ideally this system would be a remote connection, but due to time constraints it might have to be local. Do you know of a fastest way to accomplish this bi-directional connection?
