• Mocking ISession.Query<T>() for testing consumer

  - by TheCloudlessSky

  I'm trying to avoid using an in memory database for testing (though I might have to do this if the following is impossible). I'm using NHibernate 3.0 with LINQ. I'd like to be able to mock session.Query<T>() to return some dummy values but I can't since it's an extension method and these are pretty much impossible to test. Does anyone have any suggestions (other than using an in memory database) for testing session queries with LINQ?

  - by user1826663

  How can I write a recursive search that I avoid cycles. My class is this: class Component(var name: String, var number: Int, var subComponent: Set[Component]) Now I need a way to check whether a component is contained within its subcomponent or between subcomponent of its subcomponent and so on.Avoiding possible cycles caused by other Component. My method of recursive search must have the following signature, where subC is the Set [component] of comp. def content (comp: Component, subC: Set[Component]) : Boolean = { } Thanks for the help.

• Java: If I overwrite the .equals method, can I still test for reference equality with ==?

  - by shots fired

  I have the following situation: I need to sort trees based by height, so I made the Tree's comparable using the height attribute. However, I was also told to overwrite the equals and hashCode methods to avoid unpredictable behaviour. Still, sometimes I may want to compare the references of the roots or something along those lines using ==. Is that still possible or does the == comparison call the equals method?

• Reading a SquashFS archive

  - by p-static

  (SquashFS is a compressed filesystem - http://en.wikipedia.org/wiki/SquashFS) I'm looking for a way to read a SquashFS filesystem from a program. So far, I've know about the in-kernel drivers for it, but I'm sure that a userspace library for it must exist somewhere. Any language would be fine, but C is preferred. Just mounting the filesystem and using it that way is technically possible, but I'd rather avoid that route because the application I'm looking at would involve working with at least a few dozen archives at any given time.

• Are parallel calls to send/recv on the same socket valid?

  - by Jay

  Can we call send from one thread and recv from another on the same socket? Can we call multiple sends parallely from different threads on the same socket? I know that a good design should avoid this, but I am not clear how these system APIs will behave. I am unable to find a good documentation also for the same. Any pointers in the direction will be helpful.

• Is there a way through the Visual Studio IDE to move buttons between ToolStrips?

  - by Eric

  I have multiple ToolStrips with buttons on my form. I'd like to move some buttons from one ToolStrip to another. However, the Visual Studio IDE is not allowing me to drag the buttons off of a ToolStrip. I could go and edit the designer file for the form, but I try to avoid that as much as possible. So is there some way to do this through the IDE?

• Multiple requests to server question

  - by embedded

  I have a DB with user accounts information. I've scheduled a CRON job which updates the DB with every new user data it fetches from their accounts. I was thinking that this may cause a problem since all requests are coming from the same IP address and the server may block requests from that IP address. Is this the case? If so, how do I avoid being banned? should I be using a proxy? Thanks

• Algorithm to rotate an image 90 degrees in place? (No extra memory)

  - by user9876

  In an embedded C app, I have a large image that I'd like to rotate by 90 degrees. Currently I use the well-known simple algorithm to do this. However, this algorithm requires me to make another copy of the image. I'd like to avoid allocating memory for a copy, I'd rather rotate it in-place. Since the image isn't square, this is tricky. Does anyone know of a suitable algorithm?

• why is `vapply` safer than `sapply`?

  - by flodel

  The documentation says vapply is similar to sapply, but has a pre-specified type of return value, so it can be safer [...] to use. Could you please elaborate as to why it is generally safer, maybe provide examples? P.S.: I know the answer and I already tend to avoid sapply. I just wish there was a nice answer here on SO so I can point my coworkers to it. Please, no "read the manual" answer.
