  • Entity Framework 4 missing features?

    - by Roger Alsing
    I'm well aware that similair topics have been brought up before e.g. http://stackoverflow.com/questions/1639043/entity-framework-4-vs-nhibernate But instead of arguments like: NHibernate have been around longer and is more mature EF4 is drag n drop and not enterprisy EF4 and LinqToSql are ... I would like to see a more detailed list of features that you consider missing from EF4. Personally, I think the lack of enum support is the biggest drawback of EF4.

  • How to fetch parameters when using the Apache Commons CLI library

    - by Mridang Agarwalla
    I'm using the Apache Commons CLI to handle command line arguments in Java. I've figured out my way around it to a decent extent but I need a little help.

Usage: myapp [OPTION] [DIRECTORY] Options: -a Option A -b Option B How do I declare and access the DIRECTORY variable? Thank you.

  • How to change aif to be able to access 'it' within the macrocall without making 'it' public in the package

    - by Sim
    If you put the aif code presented in onlisp in a package and try to use it in another you run in the problem that packagename:it is not external. (in-package :packagename) (defmacro aif (test-form then-form &optional else-form) ‘(let ((it ,test-form)) (if it ,then-form ,else-form))) wanted call syntax (in-package :otherpackage) (aif (do-stuff) (FORMAT t "~a~%" it) (FORMAT t "just got nil~%")) How can I fix this behavior in code, without making the variable it external in the package declaration and beeing able to access it just by it instead of packagename:it?

  • How can an object not be compared to null?

    - by ProfK
    I have an 'optional' parameter on a method that is a KeyValuePair. I wanted an overload that passes null to the core method for this parameter, but in the core method, when I want to check if the KeyValuePair is null, I get the following error: Operator '!=' cannot be applied to operands of type System.Collections.Generic.KeyValuePair<string,object>' and '<null>. How can I not be allowed to check if an object is null?

  • Wrapper class for HttpGet / Post in Java?

    - by Tim Green
    Hi, Sorry, I'm quite new to Java. I've stumbled across HttpGet and HttpPost which seem to be perfect for my needs, but a little long winded. I have written a rather bad wrapper class, but does anyone know of where to get a better one? Ideally, I'd be able to do String response = fetchContent("http://url/", postdata); where postdata is optional. Thanks!

  • Tuning garbage collections for low latency

    - by elec
    I'm looking for arguments as to how best to size the young generation (with respect to the old generation) in an environment where low latency is critical. My own testing tends to show that latency is lowest when the young generation is fairly large (eg. -XX:NewRatio <3), however I cannot reconcile this with the intuition that the larger the young generation the more time it should take to garbage collect. The application runs on linux, jdk 6 before update 14, i.e G1 not available.

  • Simulating a missing gem in Ruby unit tests

    - by ktex
    Is there any way to simulate the absence of a gem for certain unit tests, short of actually uninstalling and then reinstalling the gem during testing? I am writing a command line utility, and want to make sure that my tests cover cases where a user may not have all of the gems that I support. For instance, I am using fsevents — a Leopard-specific package for monitoring filesystem events — that will never be present on other systems, as well as a growl gem that's purely optional.
