  • Is there an objective way to measure slowness of PC/WINDOWS?

    - by ekms
    We've a lot of users that usually complain about that his PC is "slow". (we use win XP). We usually check startup programs, virus, fragmentation, disk health and common problems that causes slowness (Symantec AV drops disk to 1mb/s , or a seagate HD firmware error in certain models), but in those cases the slowness is pretty evident. In other hand, the most common is the user complaining about his pc but for us looks OK, even in 6 years old desktops. People sometimes even complains about his new quad core desktops speed!!! So, we are asking if there's a way to OBJECTIVELY check that a computer didn't dropped its performance, compared with similar ones o previous measures, specially for work use (I don't think that 3dmark benchmark o similar may help). The only thing that I found that was useful is HDTune, but it only check hard disk performance. Basically, what we want is something that enable us to say to our users "see? your PC is as slow as was three years ago! stop complaining! Is all in your head!"

  • Is there some sort of CacheDependency in System.Runtime.Caching?

    - by Venemo
    I heard that .NET 4 has a new caching API. Okay, so the good old System.Web.Caching.Cache (which is, by the way, still there in .NET 4) has the ability to set so-called CacheDependency objects to determine whether a cached item is expired or not. One can also specify custom logic for determining whether a cached item is still useable or not by deriving a custom subclass from CacheDependency. I'm curious, is there a way to provide such a logic in the new API?

  • How can I access a method of the consumer class inside a method created at runtime in a method of th

    - by xxxxxxx
    I define a method inside a parametrized role that needs to create a new class at run time using Moose::Meta::Class->create and apply that exact parametrized role to it. I am also making a new method for that role using $new_class->meta->add_method( some_name => sub { my ($self) = @_; ... }) inside the sub {...} I want to access a method of the consumer class and use it for something, I have tried using $self->get_method, it didn't work, how do I do this? Please notice that the $self inside the sub above is MooseX::Role::Parameterized::Meta::Role::Parameterizable I also have another question, if I do this: my $object = Moose::Meta::Class->create( "some_type", ); Why isn't $object of type some_type and it's some ugly MooseX::Role::Parameterized::Meta::Role::Parameterizable and how do I get to the object of type some_type?

  • Should classes from the same namespace be kept in the same assembly?

    - by Dan Rasmussen
    For example, ISerializable and the Serializable Attribute are both in the System.Runtime.Serialization namespace, but not the assembly of the same name. On the other hand, DataContract attributes are in the namespace/assembly System.Runtime.Serialization. This causes confusion when a class can have using System.Runtime.Serialization but still not have reference to the System.Runtime.Serialization assembly, meaning DataContract cannot be found. Should this be avoided in practice, or is it common for namespaces to be split over multiple assemblies? What other issues should one be careful of when doing this?

  • Android: How to handle runtime exception on playing audio files?

    I have a button that plays an audio file on its click listener. If the button is clicked again and again while the audio file is being played then the app crashes. What's the solution?

  • Debugging .NET 2.0 assembly from unmanaged code in VS2010?

    - by Rick Strahl
    I’ve run into a serious snag trying to debug a .NET 2.0 assembly that is called from unmanaged code in Visual Studio 2010. I maintain a host of components that using COM interop and custom .NET runtime hosting and ever since installing Visual Studio 2010 I’ve been utterly blocked by VS 2010’s inability to apparently debug .NET 2.0 assemblies when launching through unmanaged code. Here’s what I’m actually doing (simplified scenario to demonstrate): I have a .NET 2.0 assembly that is compiled for COM Interop Compile project with .NET 2.0 target and register for COM Interop Set a breakpoint in the .NET component in one of the class methods Instantiate the .NET component via COM interop and call method The result is that the COM call works fine but the debugger never triggers on the breakpoint. If I now take that same assembly and target it at .NET 4.0 without any other changes everything works as expected – the breakpoint set in the assembly project triggers just fine. The easy answer to this problem seems to be “Just switch to .NET 4.0” but unfortunately the application and the way the runtime is actually hosted has a few complications. Specifically the runtime hosting uses .NET 2.0 hosting and apparently the only reliable way to host the .NET 4.0 runtime is to use the new hosting APIs that are provided only with .NET 4.0 (which all by itself is lame, lame, lame as once again the promise of backwards compatibility is broken once again by .NET). So for the moment I need to continue using the .NET 2.0 hosting APIs due to application requirements. I’ve been searching high and low and experimenting back and forth, posted a few questions on the MSDN forums but haven’t gotten any hints on what might be causing the apparent failure of Visual Studio 2010 to debug my .NET 2.0 assembly properly when called from un-managed code. Incidentally debugging .NET 2.0 targeted assemblies works fine when running with a managed startup application – it seems the issue is specific to the unmanaged code starting up. My particular issue is with custom runtime hosting which at first I thought was the problem. But the same issue manifests when using COM Interop against a .NET 2.0 assembly, so the hosting is probably not the issue. Curious if anybody has any ideas on what could be causing the lack of debugging in this scenario?© Rick Strahl, West Wind Technologies, 2005-2010

  • How do I compose an existing Moose role into a class at runtime?

    - by Oesor
    Say I define an abstract My::Object and concrete role implementations My::Object::TypeA and My::Object::TypeB. For maintainability reasons, I'd like to not have a hardcoded table that looks at the object type and applies roles. As a DWIMmy example, I'm looking for something along these lines in My::Object: has => 'id' (isa => 'Str', required => 1); sub BUILD { my $self = shift; my $type = $self->lookup_type(); ## Returns 'TypeB' {"My::Object::$type"}->meta->apply($self); } Letting me get a My::Object with My::Object::TypeB role applied by doing the following: my $obj = My::Object(id = 'foo') Is this going to do what I want or am I on the entirely wrong track? Edit: I simplified this too much; I don't want to have to know the type when I instantiate the object, I want the object to determine its type and apply the correct role's methods appropriately. I've edited my question to make this clearer.

  • UnmarshalException: unexpected element

  • Is there a tool for generating a DSL parser that does not require a runtime for the resultant parser

    - by Chris
    I'm doing a lot of work with a DSLs at the moment and was wondering if anyone knew of a tool that could generate a parser for my bnf specification that does not require a run-time library (pure java source parser)? I'm committed to using XTEXT for a future Eclipse plug-in but I need a nice small version for my library itself and don't want to add another jar dependency. It seems that ANTLR requires a run-time to parse files and I performed a Google search with no avail. Can anyone help out? Thanks, Chris

  • Is there a standard Java utility to parse XSD files at runtime?

    - by Andrew
    I've been looking around for a way to programmatically parse XSD files to generate an XML mapping so that I can take any XSD file and create a parser that will parse any XML file that conforms to it, and my google-fu has been coming up short. XSOM looks promising, as it will parse an XSD file and make all its attributes available in a straight forward way. Are there any other options or standard libraries available that will produce an XML file parser from an XSD file? [Conclusion] Thanks everyone for your responses, they were a real help. I was able to write implementations using JAXP, Eclipses EMF and in XSOM that all worked as desired. JAXP was very straight forward and easy to learn and do. EMF was actually a pain to get going properly, there were so many jars that had to be included for it to work standalone that I would not recommend it. XSOM was even simpler than the JAXP implementation, so I went with it in the end.

  • How to make a Django model fields calculated at runtime?

    - by Anatoly Rr
    I have a model: class Person (models.Model): name = models.CharField () birthday = models.DateField () age = models.IntegerField () I want to make age field to behave like a property: def get_age (self): return (datetime.datetime.now() - self.birthday).days // 365 age = property (get_age) but at the same time I need age to be a true field, so I can find it in Person._meta.fields, and assign attributes to it: age.help_text = "Age of the person", etc. Obviously I cannot just override Person.save() method to calculate and store age in the database, because it inevitably will become wrong later (in fact, it shouldn't be stored in the database at all). Actually, I don't need to have setters now, but a nice solution must have setting feature. Is it possible in Django, or probably there is a more pythonic and djangoic approach to my problem?

    A few months ago, I had to dynamically add a log4net appender at runtime.  Now I find myself in another log4net situation.  I need to modify the configuration of my appenders at runtime. My client requires all files generated by our applications to be saved to a specific location.  This location is determined at runtime.  Therefore, I want my FileAppenders to log their data to this specific location – but I won't know the location until runtime so I can't add it to the XML configuration file I'm using. No problem.  Bing is my new friend and returned a couple of hits.  I made a few tweaks to their LINQ queries and created a generic extension method for ILoggerRepository (just a hunch that I might want this functionality somewhere else in the future – sorry YAGNI fans): public static void ModifyAppenders<T>(this ILoggerRepository repository, Action<T> modify) where T:log4net.Appender.AppenderSkeleton { var appenders = from appender in log4net.LogManager.GetRepository().GetAppenders() where appender is T select appender as T;   foreach (var appender in appenders) { modify(appender); appender.ActivateOptions(); } } Now I can easily add the proper directory prefix to all of my FileAppenders at runtime: log4net.LogManager.GetRepository().ModifyAppenders<FileAppender>(a => { a.File = Path.Combine(settings.ConfigDirectory, Path.GetFileName(a.File)); }); Thanks beefycode and Wil Peck.

  • Can I use JPA/EJB3 on a table that was created at runtime?

    - by tieTYT
    This is weird and probably not possible but I'll ask anyway. I'm making this app that reads in a meta file and creates some tables then populates them with data. I was wondering if I could somehow use JPA to populate those tables. Obviously, there's no way I could have an entity with annotations on it since the table didn't exist at compile time. But perhaps JPA or the entity manager has a way to load data into a nameless table? If possible, I'd expect a method like entityManager.update("myTableName", hashMapOfColumnNamesAndColumnDataValues);
