  • Firefox / Iceweasel hangs at exit

    - by mxp
    On my Debian (testing) system, I found that for some time now Firefox hangs when exiting. There is no window visible anymore and the process utilizes one CPU core to 100%. No other instances can be started until that process is killed. I tried the Basic Troubleshooting guide but that didn't help. Starting it with iceweasel -safe-mode and then choosing none of the options but just clicking "quit" caused the same behavior. Creating a new profile also didn't change anything. Any ideas what else I could try?

  • Is there a portable version of Spybot Search & Destroy?

    - by NoCatharsis
    I'm trying to make everything portable, as my office IT has cracked down on native app installation. One of my favorites (and a good CYA app in this case) is Spybot. All I can find are directions on how to alter the installation to make it portable. Is there a single download out there that would put the app right onto my USB drive?

  • SimpleJdbcCall ignoring JdbcTemplate fetch size

    - by user289429
    We are calling the pl/sql stored procedure through Spring SimpleJdbcCall, the fetchsize set on the JdbcTemplate is being ignored by SimpleJdbcCall. The rowmapper resultset fetch size is set to 10 even though we have set the jdbctemplate fetchsize to 200. Any idea why this happens and how to fix it? Have printed the fetchsize of resultset in the rowmapper in the below code snippet - Once it is 200 and other time it is 10 even though I use the same JdbcTemplate on both occassion. This direct execution through jdbctemplate returns fetchsize of 200 in the row mapper jdbcTemplate = new JdbcTemplate(ds); jdbcTemplate.setResultsMapCaseInsensitive(true); jdbcTemplate.setFetchSize(200); List temp = jdbcTemplate.query("select 1 from dual", new ParameterizedRowMapper() { public Object mapRow(ResultSet resultSet, int i) throws SQLException { System.out.println("Direct template : " + resultSet.getFetchSize()); return new String(resultSet.getString(1)); } }); This execution through SimpleJdbcCall is always returning fetchsize of 10 in the rowmapper jdbcCall = new SimpleJdbcCall(jdbcTemplate).withSchemaName(schemaName) .withCatalogName(catalogName).withProcedureName(functionName); jdbcCall.returningResultSet((String) outItValues.next(), new ParameterizedRowMapper<Map<String, Object>>() { public Map<String, Object> mapRow(ResultSet rs, int row) throws SQLException { System.out.println("Through simplejdbccall " + rs.getFetchSize()); return extractRS(rs, row); } }); outputList = (List<Map<String, Object>>) jdbcCall.executeObject(List.class, inParam);

  • Can't build wxWidgets on Mac OSX. Need help, please.

    I've been trying everything but something or other always stops me cold. Now, I'm trying 2.8.10 (can't make 2.8.7 work) and I keep getting this linker error.

  • Why can't you return a List from a Compiled Query?

    - by Andrew
    I was speeding up my app by using compiled queries for queries which were getting hit over and over. I tried to implement it like this: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id) End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, List(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ (From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u).ToList()) This did not work and I got this error message: Type : System.ArgumentNullException, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : Value cannot be null. Parameter name: value However, when I changed my compiled query to return IQueryable instead of List like so: Function Select(ByVal fk_id As Integer) As List(SomeEntity) Using db As New DataContext() db.ObjectTrackingEnabled = False Return CompiledSelect(db, fk_id).ToList() End Using End Function Shared CompiledSelect As Func(Of DataContext, Integer, IQueryable(Of SomeEntity)) = _ CompiledQuery.Compile(Function(db As DataContext, fk_id As Integer) _ From u In db.SomeEntities _ Where u.SomeLinkedEntity.ID = fk_id _ Select u) It worked fine. Can anyone shed any light as to why this is? BTW, compiled queries rock! They sped up my app by a factor of 2.

  • Putting WPF Controls into canvas with Visuals

    - by Mikhail
    I am writing a WPF chart and use Visuals for performance. The code looks like: public class DrawingCanvas2 : Canvas { private List<Visual> _visuals = new List<Visual>(); private List<Visual> _hits = new List<Visual>(); protected override Visual GetVisualChild( int index ) { return _visuals[index]; } protected override int VisualChildrenCount { get { return _visuals.Count; } } public void AddVisual( Visual visual ) { _visuals.Add( visual ); base.AddVisualChild( visual ); base.AddLogicalChild( visual ); } } Beside DrawingVisual elements (line, text) I need a ComboBox in the chart. So I tried this: public DrawingCanvas2() { ComboBox box = new ComboBox(); AddVisual( box ); box.Width = 100; box.Height = 30; Canvas.SetLeft( box, 10 ); Canvas.SetTop( box, 10 ); } but it does not work, there is no ComboBox displayed. What I am missing?

  • Bitmap byte-size after decoding?

    - by need4sid
    Hi! How can I determine/calculate the byte size of a bitmap (after decoding with BitmapFactory)? I need to know how much memory space it occupies, because I'm doing memory caching/management in my app. (file size is not enough, since these are jpg/png files) Thanks for any solutions!

  • How to handle ASP.NET application error that occurs on application start and transfer & display erro

    - by Soul_Master
    I know that ASP.NET MVC has error filter attribute to handle specified error type. However, this feature cannot catch any error that occurs when application start. Therefore, I need to add some code to “Application_Error” method for handling this error like the following code. public void Application_Error(object sender, EventArgs e) { // At this point we have information about the error var ctx = HttpContext.Current; var exception = ctx.Server.GetLastError(); var errorInfo = "<br>Offending URL: " + ctx.Request.Url + "<br>Source: " + exception.Source + "<br>Message: " + exception.Message + "<br>Stack trace: " + exception.StackTrace; ctx.Response.Write(errorInfo); Server.ClearError(); } Although, this code will works fine, when normal application error occurs like error that occurs in view page. Nevertheless, it does not work when error occurs on application starting because request and response objects are always null. Next, I try to solve this question by setting default redirect in custom errors like the following code. <customErrors mode="On" defaultRedirect="Scripts/ApplicationError.htm"></customErrors> Unfortunately, it does not work because when application receive redirected request, it try to start application again and it throw exception again. How do to solve this problem? Alternatively, Do you have other idea for handling this error. Thanks, PS. The main reason for creating this handler because I want to display error when application cannot connect to other service like database for caching data on application start.

  • How do you test a new email filtering system?

    - by Zoredache
    What method do you use to test or evaluate potential new email filtering systems before you set it up on your production network? I am particularly interested in methods that are appropriate for small/medium sized organizations with a single mail server without the resources to build a duplicate of their email system.

  • Mouse button and keypress counter for Windows XP

    - by Yuval F
    I am trying to kick the habit of using a mouse where I could use keyboard shortcuts, for ergonomic reasons. I believe that if I see some statistics of my use of both input devices, I could reduce my use of mouse clicks. Do you know of any free software I can install on my Windows XP machine that counts keypresses and mouse button presses and displays an hourly/daily report? No fancy GUI is needed - just two summary lines.

  • Building using CMake-GUI

    - by goodwince
    I am trying to build Marble on Windows (XP) and have been extremely unsuccessful. Following the instructions written here. I am wanting to build it as QT only. Configuration of the build tree fails. I am using the cmake-gui since I have never tried to compile using cmake it's possible it could be something in there. I found a similar issue; however, they compiled QT using Visual Studio and I am using QT Creator which compiles with MinGW so I need to compile in a different manner. CMake-GUI configuration source-code: MyDirectory/Marble where to build: MyDirectory/Build I also added an entry as.. DQTONLY and it's value set to ON

  • Rspec > testing database views

    - by Sean McCleary
    How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

  • pthreads: reader/writer locks, upgrading read lock to write lock

    - by ScaryAardvark
    I'm using read/write locks on Linux and I've found that trying to upgrade a read locked object to a write lock deadlocks. i.e. // acquire the read lock in thread 1. pthread_rwlock_rdlock( &lock ); // make a decision to upgrade the lock in threads 1. pthread_rwlock_wrlock( &lock ); // this deadlocks as already hold read lock. I've read the man page and it's quite specific. The calling thread may deadlock if at the time the call is made it holds the read-write lock (whether a read or write lock). What is the best way to upgrade a read lock to a write lock in these circumstances.. I don't want to introduce a race on the variable I'm protecting. Presumably I can create another mutex to encompass the releasing of the read lock and the acquiring of the write lock but then I don't really see the use of read/write locks. I might as well simply use a normal mutex. Thx
