Is it better to always use a mock framework to automatically mock the dependencies of the method being tested, or would you prefer to use simpler mechanisms like for instance test stubs?

problem statement:
- a user enters several keywords/tokens
- the application searches for matches to the tokens
- need one result for each token
- ie, if an entry has 3 tokens, i need the entry id 3 times
- rank the results
- assign X points for token match
- sort the entry ids based on points
- if point values are the same, use date to sort results
What I want to be able to do, but have not figured out, is to send 1 query that returns something akin to the results of an in(), but returns a duplicate entry id for each token matches for each entry id checked.
Is there a better way to do this than what I'm doing, of using multiple, individual queries running one query per token? If so, what's the easiest way to implement those? | php | mysql | search | null | null | null | open | How-to: Ranking Search Results

I created this to copy data from one auto-generated LINQ object to another in order to get around the lack of inheritance from multiple tables in LINQ.
However, I can't help but think code like this is really 'cheating', i.e. rather than using using the provided language constructs to achieve a given end it allows you to circumvent them.

It seems like lots of people think it's a bad thing to do as described in '[Don't return in a finally clause][1]'. Scratching a little deaper, I also found '[Java's return doesn't always][2]' which shows some pretty horrible examples of other types of flow control in finally blocks.
So, my question is, can anyone give me an example where a return statement (or other flow control) in a finally block produces better / more readable code?

I'm looking for a way to monitor individual CPU core usage on these servers. It is possible for an end-user to have a run-away process (e.g. Internet Explorer or Outlook). The core for that process may spike to near 100% leaving the other cores 'normal'. Thus, the overall CPU usage on the server is just the total of all the cores or if 7 of the cores on a 8 core server are idle and the 8th is running at 100% then 1/8 = 12.5% usage.
What utility can I use to monitor multiple servers ? If the CPU usage for a core is "high" what would I use to determine the offending process and then how could I automatically kill that process if it was on the 'approved kill process' list?
A product from http://www.packettrap.com/ called PT360 would be perfect except they use SMNP to get data and SMNP appears to only give total CPU usage, it's not broken out by an individual core. Take a look at their Dashboard option with the CPU gauge 'gadget'. That's exactly what I need if only it worked at the core level.
Any ideas?

For every request, I get back (among other things) a list of which routes serve the stop in question. For example, if the list includes result for bus route #1, 2, and 5, then I know that those serve this stop.
I have a many-to-many relationship set up between Route and Stop, and I want to dynamically check and update these associations on every request. There is no "master list" of which routes serve which stops, so this seems like the best way to get this data.

According to MSDN; "The main window is the window that is created when the process is started. After initialization, other windows may be opened, including the Modal and TopLevel windows, but <em>the first window associated with the process remains the main window</em>." (Emphasis added)
But while debugging I noticed that MainWindowHandle seemed to change value... which I wasn't expecting, especially after consulting the documentation above.
To confirm the behaviour I created a standalone WinForms app with a timer to check the MainWindowHandle of the "DEVENV" (Visual Studio) process every 100ms.
Here's the interesting part of this test app...
IntPtr oldHWnd = IntPtr.Zero;
void GetMainwindowHandle()
{
Process[] processes = Process.GetProcessesByName("DEVENV");
if (processes.Length!=1)
return;
IntPtr newHWnd = processes[0].MainWindowHandle;
if (newHWnd != oldHWnd)
{
oldHWnd = newHWnd;
textBox1.AppendText(processes[0].MainWindowHandle.ToString("X")+"\r\n");
}
}

{

You can see the value of MainWindowHandle changing when you (for example) click on a drop-down menu inside VS.

Our approach, so far, has been to try and pick your components carefully, choosing ones that have a clearly defined API, preferably via HTTP (like REST or SOAP), though that isn't always possible (we haven't found a decent forum that works that way).

The questions page is a load of random stuff. It moves quickly (some might say, too quickly) and contains a huge number of questions that I'm not interested in.
The idea, I imagine, is that we can use tags to find questions that we're interested in. However, I'm not sure that this works: you can't use tags negatively. I'm _not_ interested in PHP or perl or web development. I want to _exclude_ such posts. But with the tags, I can't.
Although discrete subforums are in a sense less flexible, as they generally force you to pick a category even if a question might fit into two (if SO had, say, areas for "Web Development", "Games development", "Computer Science", "Systems Programming", "Databases", etc. then sure, some people might want to post about developing of web-based games, for example) is it worth sacrificing some of that flexibility in order to make it easier to find the content that you are interested in, and hide the content that you are not interested in?
Is there any way with a pure tagging system to achieve the greater ease of use that subforums provide?

The is correct according to Scrum, but here's the problem.
Despite suggestions to the contrary, testers never help with non-test tasks and developers never help with non-dev tasks, so we are not cross functional team members at all. Also, despite various suggestions, testers normally spend the first few days of each sprint waiting for something to test.
The end result is that typically we take on far more dev work than we actually have capacity for in the sprint. For example, the developers might contribute 20 days to the velocity calculation and the testers 10 days.

I'm using Eclipse 3.4 (Ganymede) with CDT 5 on Windows.
When the integrated spell checker doesn't know some word, it proposes (among others) the option to add the word to a user dictionary.
If the user dictionary doesn't exist yet, the spell checker offers then to help configuring it and shows the "General/Editors/Text Editors/Spelling" preference pane. This preference pane however states that **"The selected spelling engine does not exist"**, but has no control to add or install an engine.
How can I put a spelling engine in existence? | 0 |

For a specific example of a project I'm working on : a list of unique id / name pairs are being retrieved from a remote web-service.
- this list will change infrequently (once per day),
- will be read-only from the point of view of the application where it is being used
- will be stored at the application level for all requests to access
Given those points, I plan to store the returned values at the application level in a singleton class.
My initial approach was to iterate through the list returned from the remote service and store it in a NameValueCollection in a singleton class, with methods to retrieve from the collection based on an id:
sugarsoap soapService = new sugarsoap();
branch_summary[] branchList = soapService.getBranches();
foreach (branch_summary aBranch in branchList)
{
branchNameList.Add(aBranch.id, aBranch.name);
}
The alternative using LINQ is to simply add a method that works on the list directly once it has been retrieved:
public string branchName (string branchId)
{
//branchList populated in the constructor
branch_summary bs = from b in branchList where b.id == branchId select b;
return branch_summary.name;
}
Is either better than the other - is there a third way? I'm open to all answers, for both approaches and both in terms of solutions that offer elegance, and those which benefit performance. | c# | linq | null | null | null | null | open | Pros & cons between LINQ and traditional collection based approaches

I know very well that estimating so far into the future regarding a problem-set of unknown size is not a good recipe for a successful estimate. However for a variety of reasons, a defined number of hours invariably gets assigned at the outset to this segment of work. And the farther off this initial estimate is from the real, final value, the more grief those involved with the debugging will have to take later on when they go "over" the estimate.
So my question is: what is the best strategy you have seen with regards to making estimates like this? A flat percentage of the overall dev estimate? Set number of hours (with the expectation that it will go up)?
