i've found an example showing how to call ejb methods in asynchronous fashion. Do you use asynchronous proxy in EJB 3.0 on Jboss AS and does it work as it should?
Does the copy_from_user function, declared in uaccess.h, modify the (void __user *)from pointer?
The pointer isn't declared as const in the function declaration, only the contents it points to.
The reason I ask is that I want to use copy_from_user twice, with the second copy_from_user copying from the place where the first one finished.
I was…
In allusion to Dare Obasanjo's impressions on Map, Reduce, Filter (Functional Programming in C# 3.0: How Map/Reduce/Filter can Rock your World) "With these three building blocks, you could replace the majority of the procedural for loops in your application with a single line of code. C# 3.0 doesn't just stop there."
Should we increasingly use…
I have been banging my head against the wall for a couple days and need some help. I have a feeling that I am doing something really silly here, but I cannot find the issue. This is the controller for a table view. I put the SQL in line to simplify it as part of the troubleshooting of this error. Normally, it would be in an accessor method…
I'm currently diving into the inner workings of .net, which means IL. As an exercise, I want to build a brainf..k compiler for .net (yes, they already exist, but as said it's for learning purposes).
For the moment I'm just writing some text files that contain .il and compile them with ilasm, which works. But I wonder if I could/should go one…
TortoiseHg allows you to email a patch file of your changes to someone, but does it support applying patches?
If so, how do you apply a patch using TortoiseHg?
Solution
Thanks @Will Bickford for your help. I just found this feature listed as a TODO on the TortoiseHg site.
Hello everyone:
I am trying to analyze my agent results from a collection of 20 txt files here.
If you wonder about the background info, please go see my page, what I am doing here is just one step.
Basically I would like to take only my agent's result out of the messy context, so I've got this command for a single file:
cat run15.txt |…
I copy stuff from output buffers into C++ code I'm working on in vim.
Often this output gets stuck into strings. And it'd be nice to be able to escape all the control characters automatically rather than going back and hand editing the pasted fragment.
As an example I might copy something like this:
error in file "foo.dat"
And need to…
I am using the latest NHibernate 2.1.0Beta2. I'm trying to unit test with SQLite and have the configuration set up as:

Where each link will be different in length and value.

I'm trying to understand how a while loop looks in IL. I have written this C# function:
static void Brackets()
{
while (memory[pointer] > 0)
{
// Snipped body of the while loop, as it's not important
}
}
The IL looks like this:
.method private hidebysig static void Brackets()…
I have a table that describes which software versions were installed on a machine at various times:
machine_id::integer, version::text, datefrom::timestamp, dateto::timestamp
I'd like to do a constraint to ensure that no date ranges overlap, i.e. it is not possible to have multiple software versions installed on a machine at the…
I'm trying to emulate the scroll views in a UIPickerView. You can scroll these freely (as opposed to paging in a UIScrollView) but they always decelerate and stop at precise increments, alongside the dates.
Any idea how this is performed? I can't seem to think of a way to implement it.
I'm asking with regards to c#, but I assume its the same in most other languages.
Does anyone have a good definition of expressions and statements and what the differences are.
Thanks in advance.

I've got an application that has a bug right now, but we're unable to update the end-user to get the fix out. What a possible workaround would be is to change the working directory to the application's install directory, but from what I can tell, there's no way to do that…
