  • <:< operator in scala.

    - by scout
    Can anybody provide some details on <:< operator in scala. I think if(apple <:< fruit) //checks if apple is a subclass of fruit. Are there any other explanations? I see many definitions in the scala source file.

  • Collapsing parent POM into the child

    - by Robert Munteanu
    Given a maven project with a parent POM - including mostly plugin and dependency versions - how can I generate a POM which takes the information from the parent, places it into the child and removes the reference to the parent? Ideally this would be done with the maven-assembly-plugin. Update: I need this done automatically, since manually it's boring and tedious. Update 2: I'm preparing the source code for an external and want to deliver only one project, not the whole family.

  • How does Lucene work

    - by Midhat
    I am trying to find out how lucene search works so fast. Cant find any useful docs on the web. If you have anything (short of lucene source code) to read, let me know. A text search query using mysql5 text search with index takes about 18 minutes in my case. A lucene search for the same query takes less than a second

  • AES-XTS implementation in C#

    - by Ranhiru
    Is there any implementation of AES-XTS written in C# available in the Internet? Bouncy Castle disappointed me :( I took the source codes of TrueCrypt and FreeOTFE but they are written in C which is very hard for me to understand... Anyone?

  • Browser side code editor component

    - by Serious
    Hello, do you know any browser-side component, in HTML/Javascript, Flash, Applet or Silverlight, that would allow source code edition with syntax highlighting and auto-completion. CodeMirror has a good syntax highlighting support but does not seem to support auto-completion. If no such editor exists do you know any way to implement auto-completion using HTML and javascript or any other browser-side technology ? Thanks by advance.

  • Does the openssl command line do key strengthening?

    - by chotchki
    If I run the openssl command line in hmac mode (as below), is the key used for the hmac used directly or is it hashed before using it as the key? echo "foo" | openssl dgst -sha256 -binary -hmac "test" | openssl base64 Similarly, when encrypting a file with openssl (as below)is the pass phrase hashed with the salt? (If so how is it done? A pointer to the right source file would be even better.) openssl enc -salt

  • Flex unit testing with ANT vs Flash Builder 4

    - by peterlindstrom21
    I have just tried setup unit testing in Flash Builder 4, and it working nicely. A setup of a parallel test source structure and using Flash Builder 4:s new TestCase and new TestSuite I was up and running with some testcases within minutes. But now I want to compile them from a ant flex task, the Flash Builder generates FlexUnitApplication.mxml and FlexUnitCompilerApplication.mxml. Is there a nice way to build the unit tests with ant using these? I cant find any sample where this is done.

What are the starting locations we can get at to start making existing code work in different browsers?

  • Eclipse Javadoc tooltip help doesn't show classes' supertypes and interfaces

    - by Pooria
    I'm talking about the tooltip that pops up when you hover your mouse over a class in your source (which also helps with intellisense and auto completion), which describes what a class/method/etc does. I find it very annoying that it doesn't show what superclass the class (being described) extends or what interfaces it implements. Is there a way to make eclipse show the additional information?

  • Type problem with Observable.Create from Boo

    - by Tristan
    I'm trying to use Reactive Extensions from Boo and am running into type problems. Here's the basic example: def OnSubscribe(observer as IObservable[of string]) as callable: print "subscribing" def Dispose(): print "disposing" return Dispose observable = System.Linq.Observable.Create[of string](OnSubscribe) observer = System.Linq.Observer.Create[of string]({x as string | print x}) observable.Subscribe(observer) The Subscribe here gives a System.InvalidCastException: Cannot cast from source type to destination type. The issue appears to be with how I'm creating the observable, but I've struggled to see where the type problem arises from. Ideas?

  • Show context menu when link is long pressed in TextView

    - by Al
    I have a TextView with its MovementMethod set to LinkMovementMethod. Text added to the TextView is a combination of normal text and URLs. For URLs, I would like to offer a context menu when the URL is long pressed for doing things such as copying the address. I've had a look at the source for LinkMovementMethod but it doesn't seem to have any long pressed related code I could override. Any ideas on how to go around achieving this?

  • ede-proj-regenerate does weird things with my Makefile

    - by Xavier Maillard
    Hi, I have created a really basic project (Make) like this: (ede-proj-project "zrm" :name "zrm" :file "Project.ede" :targets (list (ede-proj-target-makefile-program "zm" :name "zrm" :path "" :source '("zrm.c") ) ) ) When doing M-x ede-proj-regenerate RET and M-x compile RET RET (accepting make -k as my compile command), make keeps bailing with a **missing separator error. When editing my Makefile outside of Emacs (with the darn evil vi) and replacing spaces by tabs, it works. Is there anything special I should pay attention in order to have this work ? Regards

  • How do I identify an ASP.NET MVC website?

    - by Alejandro
    I am trying to determine whether a company has websites built with ASP.NET MVC in their portfolio. Is there a reliable way of determining that without asking them assuming that I can visit the website in question in my browser? This might seem simple, but I wasn't able to find this information online. I would think that the lack of viewstate related stuff in the HTML source and the noun-verb URL structure would be good indicators. Are there any other indicators?
