  • can't install sun jdk on ubuntu karmic 9.10

    - by pstanton
    i've just started using a new ec2 install of ubuntu karmic 9.10 and my first task was to install the jdk. when running apt-get install sun-java6-jdk i get the following: Reading package lists... Done Building dependency tree Reading state information... Done Package sun-java6-jdk is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package sun-java6-jdk has no installation candidate i've tried apt-get update as well as adding deb http://us.archive.ubuntu.com/ubuntu/ karmic universe to /etc/apt/sources.list any ideas fellas?

  • Outlook collapses IMAP folders by default

    - by Aron Rotteveel
    I recently switched my mail account from POP3 to IMAP and created server-side rules to help me manage my mail better. I use Outlook 2007 as a mail client. For some reason, it seems then ever since I switched to IMAP, all my folders are collapsed by default. Since my folder tree goes down 4 levels, this is pretty annoying. I don't know any better than Outlook remembering my folder preferences, but it seems to forget them as soon as I close the program now. Is there any cause for this, and more importantly, is there a known fix for this problem?

  • Configure Supervisor to manage init.d services

    - by Eduard Luca
    I installed uwsgi and created a bash script, which allows me to start/stop uwsgi in the following manner: service uwsgi [start|stop]. This bash script is located in /etc/init.d/uwsgi. Now, I want to (politely) ask Supervisor to use that script to manage the uwsgi process. All the tutorials indicate that this is not the way to do it, however I do want to be able to do both service uwsgi stop and supervisorctl stop uwsgi (not sure if I nailed the syntax of the latter) -- even though I am aware that the first one will not in fact stop my service because supervisor will restart it (that's exactly what I need). Note that I'm using uwsgi in emperor mode if that matters in any way.

  • SELinux Contexts

    - by Josh
    I am configuring Apache\PHP and noticed Apache complaining about permissions with the php shared object. Starting httpd: httpd: Syntax error on line 206 of /etc/httpd/conf/httpd.conf: Cannot load /usr/lib/httpd/modules/libphp5.so into server: /usr/lib/httpd/modules/libphp5.so: cannot restore segment prot after reloc: Permission denied I looked at the context (started fine with enforcement off) and found: [root@HDSSERVER conf]# ls --lcontext /usr/lib/httpd/modules/libphp5.so -rwxr-xr-x 1 root:object_r:httpd_modules_t root root 15565418 May 10 08:39 /usr/lib/httpd/modules/libphp5.so Shouldn't httpd (apache) be able to access files with a context of httpd_modules_t? I got it fixed by applying chcon -t textrel_shlib_t '/usr/lib/httpd/modules/libphp5.so' But I would think the httpd version would work before this one. Can someone explain this to me?

  • Adding custom attribute to openldap

    - by arukaen
    I am attempting to setup ConTagged - The LDAP Address Book but I am having a few issues with some of the attributes. The problem is that some of them are undefined and they do not seem to be in the inetorgperson.schema. How do I set these custom attributes? For reference, here is the exact error I receive whenever I make a change to a contact. The LDAP server returned the following errors Invalid syntax Undefined attribute type(del anniversary) Undefined attribute type(del marker) Object class violation(mod c) Undefined attribute type(del custom1) Undefined attribute type(del custom2) Undefined attribute type(del custom3) Undefined attribute type(del custom4)

  • Specification, modeling and programming are principially the same, right?

    - by Gabriel Šcerbák
    In formal specifications based on abstract algebraic types and equational theory you use formulas of equational theory to specify theory. System which will satisfy those constraints is called in formal logic a model. Modeling is process of creating a model, which abstracts of some aspects, which are unnecessary details for a specific case. So concrete system has to adhere to created model in observed aspects. Programming is a process of creating a program which will have specific behaviour - will perform specific algorithms - and programming languages through different paradigms enable us to think in a certain specific way, which abstracts of some details, usually machine specific ones. So could we be doing all those things at the same time, because they are principially the same? Is declarative programming the nearest attempt to do that? Could we use some sort f programming languages which will be good for programming as well as for modeling and specification?

  • Good articles to read on SSL and HTTPS?

    - by Igor Romanov
    I had a problem with accepting invalid SSL certificate in my iPhone program. That problem is solved now, however I came to understanding that I have very abstract idea on how exactly the whole thing is working: how web browser is verifying that received certificate is really for host it communicates to and not faked by same party in the middle? if browser talks to some 3rd party (CA?) to do certificate check? and many other questions... Would someone please recommend good source of information with in-depth enough description of how all parts click together?

  • Specifying distinct sequence per table in Hibernate on subclasses

    - by gutch
    Is there a way to specify distinct sequences for each table in Hibernate, if the ID is defined on a mapped superclass? All entities in our application extend a superclass called DataObject like this: @MappedSuperclass public abstract class DataObject implements Serializable { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) @Column(name = "id") private int id; } @Entity @Table(name = "entity_a") public class EntityA extends DataObject { ... } @Entity @Table(name = "entity_b") public class EntityB extends DataObject { ... } This causes all entities to use a shared sequence, the default hibernate_sequence. What I would like to do is use a separate sequence for each entity, for example entity_a_sequence and entity_b_sequence in the example above. If the ID were specified on the subclasses then I could use the @SequenceGenerator annotation to specify a sequence for each entity, but in this case the ID is on the superclass. Given that ID is in the superclass, is there a way I can use a separate sequence for each entity — and if so, how? (We are using PostgreSQL 8.3, in case that's relevant)

    Hello, I wrote the question as a comment in the code, I think its easier to understand this way. public class Xpto{ protected AbstractClass x; public void foo(){ // AbstractClass y = new ????? Car or Person ????? /* here I need a new object of this.x's type (which could be Car or Person) I know that with x.getClass() I get the x's Class (which will be Car or Person), however Im wondering how can I get and USE it's contructor */ // ... more operations (which depend on y's type) } } public abstract class AbstractClass { } public class Car extends AbstractClass{ } public class Person extends AbstractClass{ }

  • MongoDB on FreeBSD

    - by Hartator
    We are currently using MongoDB 2.0.0 on MacOS but our servers are running FreeBSD. The most recent port of MongoDB is the 1.8.3 version. I have tried to compile the 2.0.0 by hand but I came across errors that I didn't manage to fix. I came across on the Internet a few old resources which are saying that MongoDB does not run well on FreeBSD mainly for performance issue (memory mapped files). Is that true ? Does it mean we have to switch our server to another OS ? Thanks for your opinions!

  • groovy call private method in Java super class

    - by Jeff Storey
    I have an abstract Java class MyAbstractClass with a private method. There is a concrete implementation MyConcreteClass. public class MyAbstractClass { private void somePrivateMethod(); } public class MyConcreteClass extends MyAbstractClass { // implementation details } In my groovy test class I have class MyAbstractClassTest { void myTestMethod() { MyAbstractClass mac = new MyConcreteClass() mac.somePrivateMethod() } } I get an error that there is no such method signature for somePrivateMethod. I know groovy can call private methods but I'm guessing the problem is that the private method is in the super class, not MyConcreteClass. Is there a way to invoke a private method in the super class like this (other than using something like PrivateAccessor)? thanks Jeff

  • How do I implement a custom Brush in WPF?

    - by MojoFilter
    Where can I find out enough info about how Brushes work to implement my own System.Windows.Media.Brush? I can handle all of the freezable baggage, but it's not really obvious what I need to override to get it to work. Yeah, so I didn't mean that I want to use a predefined brush. I want to extend System.Windows.Media.Brush, which is an abstract class. This is all purely for my own edification. I'm not even sure what kind of brush I could make. I was just trying to learn how brushes work. As in: public AwesomeBrush : Brush { protected override Freezable CreateInstanceCore() { return new AwesomeBrush(); } ... // concrete brush stuff }

  • rsync option --log-file seems is not working

  • VB to C# conversion incongruency with lambdas

    - by Jason
    I have a bit of code that I have been tasked with converting to C# from VB. A snippet of mine seems like it cannot be converted from one to the other, and if so, I just don't know how to do it and am getting a little frustrated. Here's some background: OrderForm is an abstract class, inherited by Invoice (and also PurchaseOrder). The following VB snippet works correctly: Dim Invs As List(Of OrderForm) = GetForms(theOrder.OrderID) .... Dim inv As Invoice = Invs.Find( Function(someInv As Invoice) thePO.SubPONumber = someInv.SubInvoiceNumber) In C#, the best I came to converting this is: List<OrderForm> Invs = GetForms(theOrder.OrderID); .... Invoice inv = Invs.Find( (Invoice someInv) => thePO.SubPONumber == someInv.SubInvoiceNumber); However, I get the following error when I do this: Cannot convert lambda expression to delegate type 'System.Predicate' because the parameter types do not match the delegate parameter types Is there any way to fix this without restructuring my whole codebase?

  • NHibernate with or without Repository

    - by Groo
    There are several similar questions on this matter, by I still haven't found enough reasons to decide which way to go. The real question is, is it reasonable to abstract the NHibernate using a Repository pattern, or not? It seems that the only reason behind abstracting it is to leave yourself an option to replace NHibernate with a different ORM if needed. But creating repositories and abstracting queries seems like adding yet another layer, and doing much of the plumbing by hand. One option is to use expose IQueryable<T> to the business layer and use LINQ, but from my experience LINQ support is still not fully implemented in NHibernate (queries simply don't always work as expected, and I hate spending time on debugging a framework). Although referencing NHibernate in my business layer hurts my eyes, it is supposed to be an abstraction of data access by itself, right? What are you opinions on this?

  • Referring to the type of an inner class in Scala

    - by saucisson
    The following code tries to mimic Polymorphic Embedding of DSLs: rather than giving the behavior in Inner, it is encoded in the useInner method of its enclosing class. I added the enclosing method so that user has only to keep a reference to Inner instances, but can always get their enclosing instance. By doing this, all Inner instances from a specific Outer instance are bound to only one behavior (but it is wanted here). abstract class Outer { sealed class Inner { def enclosing = Outer.this } def useInner(x:Inner) : Boolean } def toBoolean(x:Outer#Inner) : Boolean = x.enclosing.useInner(x) It does not compile and scala 2.8 complains about: type mismatch; found: sandbox.Outer#Inner required: _81.Inner where val _81:sandbox.Outer From Programming Scala: Nested classes and A Tour of Scala: Inner Classes, it seems to me that the problem is that useInnerexpects as argument an Inner instance from a specific Outer instance. What is the true explanation and how to solve this problem ?

  • identifying the type

    - by Gokul
    Hi, In my application, there is a inheritance hierarchy in which only the classes that are at the end of the inheritance chain are non-abstract classes. Also there is some usage of boost::variant. I want to write a function which takes a pointer and a Type and says whether the object belongs to that type. For example template< typename Type, bool TypeisAbstract, typename ptrType > bool checkType( ptrType* t) { return ( typeid(*t) == typeid(Type) ); } template< typename Type, typename ptrType > bool checkType<Type, true, ptrType>( ptrType* t) { return ( dynamic_cast<Type*>(t) != NULL ); } Now if there is a boost variant, i want to find out whether the boost variant stores that particular type. Can someone help me with that? Thanks, Gokul.

  • Is it possible to overwrite a static method in parent class?

    - by MartinDenny2069
    I have a static method defined in a base class, I want to overwrite this method in its child class, is it possible? I tried this but it did not work as I expected. When I created an instance of class B and invoke its callMe() method, the static foo() method in class A is invoked. public abstract class A { public static void foo() { System.out.println("I am base class"); } public void callMe() { foo(); } } Public class B { public static void foo() { System.out.println("I am child class"); } }

  • Monit wont start/stop any processes

    - by Vaughan Magnusson
    Hi, I've got monit running on a linux vserver, installed in a custom location /home/user/bin/monit as that is the only suitable location according to the webhost providers. When I installed monit I used ./configure --prefix=/home/user Monit itself runs, and sends me emails of it's activity, and the control file syntax is correct. However, monit cannot seem to start or stop anything - or even run the simplest of scripts. eg. Using 'monit stop all', I try to run the following stop command stop = "/bin/bash /home/user/simple_script.sh" Which fails (and says so in the log). I cant figure out why this is failing, can anyone help with this?

  • ASP.NET MVC IoC usability

    - by Andrew Florko
    Hello everybody, How often do you use IoC for controllers/DAL in real projects? IoC allows to abstract application from concrete implementation with additional layer of interfaces that should be implemented. But how often concrete implementation changes? Should we really have to do job twice adding method to interface then the implementation if implementation hardly will ever be changed? I took part in about 10 asp.net projects and DAL (ORM-like and not) was never rewritten completely. Watching lots of videos I clearly understand that IoC "is cool" and the really nice way to program, but does it really needed?

  • Can I save an Apache environment variable value with SetEnv?

    - by Nicholas Tolley Cottrell
    I am running Apache 2.2 with Tomcat 6 and have several layers of URL rewriting going on in both Apache with RewriteRule and in Tomcat. I want to pass through the original REQUEST_URI that Apache sees so that I can log it properly for "page not found" errors etc. In httpd.conf I have a line: SetEnv ORIG_URL %{REQUEST_URI} and in the mod_jk.conf, I have: JkEnvVar ORIG_URL Which i thought should make the value available via request.getAttribute("ORIG_URL") in Servlets. However, all that I see is "%{REQUEST_URI}", so I assume that SetEnv doesn't interpret the %{...} syntax. What is the right way to get the URL the user requested in Tomcat?
