Currently I am:
1. Actually disconnecting the network wire from the back of my computer
2. using ipconfig /release
3. Using the [cports][1] program to close out the socket completely
None of these methods though are ideal for me, and I'd like to emulate network problems more easily.
I would like for sometimes connects to fail, sometimes socket reads to fail, and sometimes socket writes to fail. It would be great if there was some utility I could use to emulate these types of problems.
It would also be nice to be able to build some automated unit tests while this emulated bad network is up.

It's been my experience in the past that the "10-1" rule for developers (good devs are 10 times more productive than mediocre devs) is even more prevalent for testers. Most testers I've worked with found a decent amount of issues, but there's a few stand-out testers that I've worked with that could rip applications apart and make the dev team cry.
So the question is -- how do you find these rockstar testers? The web is full of exams and tips to separate out the great from mediocre developers, but whats the magic interview questions and tests to find the amazing testers?
We're about to start the second round of interviewing with the people that have passed the phone screen (aka idiot test) and any suggestions you have for this challenge greatly appreciated.

Note: I am not talking about [comments within the code][1]
By "value limits", I mean:
- does a parameter can support a null value (or an empty String, or...) ?
- does a 'return value' can be null or is guaranteed to never be null (or can be "empty", or...) ?
Sample:
What I often see (without having access to source code) is:
/**
* Get all readers name for this current Report. <br />
* <b>Warning</b>The Report must have been published first.
* @param aReaderNameRegexp filter in order to return only reader matching the regexp
* @return array of reader names
*/
String[] getReaderNames(final String aReaderNameRegexp);
What I *like to see* would be:
/**
* Get all readers name for this current Report. <br />
* <b>Warning</b>The Report must have been published first.
* @param aReaderNameRegexp filter in order to return only reader matching the regexp
* (can be null or empty)
* @return array of reader names
* (null if Report has not yet been published,
* empty array if no reader match criteria,
* reader names array matching regexp, or all readers if regexp is null or empty)
*/
String[] getReaderNames(final String aReaderNameRegexp);
My point is:
When I use a library with a getReaderNames() function in it, I often do not even need to read the API documentation to guess what it does. But I need to be sure ***how to use it***.
My only concern when I want to use this function is: what should I expect in term of parameters and return values ? That is all I need to know to safely setup my parameters and safely test the return value, yet I almost never see that kind of information in API documentation...
What do you think ? value limits and API, do they belong together or not ?

In a web application this doesn't happen: when the user clicks a link their keystrokes are then lost until the form on the following page is dispayed. Does anyone have any tricks for preventing this? Do I have to move away from using separate pages and use AJAX to embed the form in the page using something like [GWT][1], or will that still have the problem of lost keystrokes?

This [post by Andrew Connell][1] litterally changed the way I work.
I'm thinking about switching to Fusion and running everything in OS X but I wasn't able to answer the following questions about VM Fusion/Workstation/Server. **I need to know if the following features from Virtual PC/Server exist in their VMWare counter parts.**
1. Differencing Disks (ability to create a Base VM and provision new VMs which just add deltas on top of the base [saves a ton of disk space, and makes it easy to spin up new VMs with a base set of funcitonality]).
2. Undo disks (ability to rollback all changes to the VM within a session).
3. Easily NAT out a different subnet for the VM to sit in.
4. Share VMs between VM Player and VM Server. I'd like to build up a VM locally (on OS X/Fusion) and then move it to some server (Win2k3/Win2k8 and VM Server) and host it there but with VM Server.
5. An equivalent to Hyper-V.
6. Ability to Share disks between multiple VMs. If I have a bunch of databases on a virtual disk and want them to appear on more than one VM I should be able to just attach them.
7. (Nice to have) Support for multiple processors assigned to a VM .
**Is there a VMWare guru out there who knows for sure that the above features are available on the other side?**
**Also the above has been free (as long as you have licenses for Windows machines), besides buying Fusion are there any other costs?**

public partial class Home : ViewMasterPage
On Home.Master there is a display statement like this:
<%= ((GenericViewData)ViewData["Generic"]).Skin %>
However, a developer on the team just changed the assembly references to Preview 4.
Following this, the code will no longer populate ViewData with indexed values like the above.
Instead, ViewData["Generic"] is null.
As per [this question][1], ViewData.Eval("Generic") works, and ViewData.Model is also populated correctly.
However, the reason this solution isn't using typed pages etc. is because it is kind of a legacy solution. As such, it is impractical to go through this fairly large solution and update all .aspx pages (especially as the compiler doesn't detect this sort of stuff).
I have tried reverting the assemblies by removing the reference and then adding a reference to the Preview 3 assembly in the 'bin' folder of the project. This did not change anything. I have even tried reverting the Project file to an earlier version and that still did not seem to fix the problem.
I have other solutions using the same technique that continue to work.
Is there anything you can suggest as to why this has suddenly stopped working and how I might go about fixing it (any hint in the right direction would be appreciated)?

Ok, so there has to be a way to do this... no? If not I'd love some ideas.
I have two repeaters and an image inside an update panel along with some AJAX dropdowns with link buttons to the left. I want to update the data inside the update panel as fast as possible as values are selected from the dropdowns.
What do you think would be the best way to update the data? The repeaters are populated by objects, so if I could just filter the objects by some properties I could end up with the correct data. No new data from the server is needed.

That is to say, I am posing a question, and would like to see answers given for a number of different languages so that someone moving from one language to another can see how some typical operation is done. I have always found these types of comparisons to be very educational when moving into a new language, and a fun quick way to see differences between languages without having to use them heavily for a while.
This particular question is, given an array of items in the typical collection appropriate to the language at hand, how do you sort them? Sample code with some description would be good.
I'll present the Objective C answer:
// Can only modify mutable arrays
NSMutableArray *sortArray = [NSMutableArray arrayWithArray:myArrayOfStuff];
Sort NSString ignoring case:
[sortArray sortUsingSelector: @selector(caseInsensitiveCompare:)];
Sort most foundation objects (would also work for NSString as well), assuming numbers are wrapped in NSNumber class:
[sortArray sortUsingSelector:@selector(compare:)];
Sort instances of your own classes:
[sortArray sortUsingSelector:@selector(myCompare:)];
For the last one, in your class you'd implement a comparison method like so:
// Class instance method to compare self with object "obj"
- (NSComparisonResult) myCompare:(myObject *)obj
{
NSComparisonResult retVal = NSSame;
if ( self < obj ) // by whatever rules make sense for your class of course
retVal = NSAscending;
else if ( self > obj )
retVal = NSDescending;
return result;

We brought in a new team of .NET/ SQL Programmers to do the rewrite. Most of the system is already completed with the Dollar amounts using Floats. The legacy system language, I programmed in, did not have a Float so I probably would have used a Decimal.
What is your recommendation?
Should Float or Decimal data type be used for dollar amounts?
What are some of the pros and cons for either?
One Con mentioned in our daily scrum was you have to be careful when you calculate an amount that returns a result that is over two decimal positions. It sounds like you will have to round the amount to two decimal positions.
Another Con is all displays and printed amounts have to have a Format Statement that shows two decimal positions. I noticed a few times where this was not done and the amounts did not look correct. (i.e. 10.2 or 10.2546)
A pro is the Float only takes up 8 bytes on disk where the Decimal would take of 9 bytes (Decimal 12,2)

siteroot/
models/
controllers/
controller1/
controller2/
...
templates/
template1/
template2/
...
..etc. The controllers will be Python modules handling requests. They would then need to locate (Django-style) templates in associated folders. Most of the demo apps I've seen resolve template paths like this:
path = os.path.join(os.path.dirname(__file__), 'myPage.html')
...the __ file __ property resolves to the currently executing script. So, in my above example, if a Python script were running in controllers/controller1/, then the 'myPage.html' would resolve to that same directory -- controllers/controller1/myPage.html -- and I would rather cleanly separate my Python code and templates.
The solution I've hacked together feels... hacky:
base_paths = os.path.split(os.path.dirname(__file__))
template_dir = os.path.join(base_paths[0], "templates")
So, I'm just snipping off the last element of the path for the currently running script and appending the template directory to the new path. The other (non-GAE specific) solutions I've seen for resolving Python paths seem pretty heavyweight (such as splitting paths into lists and manipulating accordingly). Django seems to have an answer for this, but I'd rather stick to the GAE API, vs. creating a full Django app and modifying it for GAE.
I'm assuming anything hard-coded would be non-starter, since the apps live on Google's infinite server farm. So what's a better way?

Now when we load from the database an object from class Foo using session get e.g:
Foo foo = (Foo)session.get(Foo.class, 1 /* or some other id that exists in the DB*/);
the Bar member of foo is a proxy object (in our case javassist proxy but it can be cglib one depending on the bytecode provider you use), that is not initialized.
If you then use session.get to fetch the Bar object that is the member of the Foo class just loaded (we are in the same session), Hibernate does not issue another DB query and fetches the object from the session (first level) cache. The problem is this is a proxy to Bar class which is not initialized and trying to call this object getId() will return 0, and getTitle() will return null.
Our current solution is pretty ugly and checks if the object returned from get is a proxy here is the code (form a generic DAO implementation):
@SuppressWarnings("unchecked")
@Override
@Transactional(readOnly = true)
public <T extends IEntity> T get(Class<T> clazz, Serializable primaryKey) throws DataAccessException {
T entity = (T) currentSession().get(clazz, primaryKey);
if (entity != null) {
if (LOG.isWarnEnabled()) {

HibernateProxy proxy = (HibernateProxy)entity;
if (!Hibernate.isInitialized(proxy)) {

}
entity = (T)proxy.getHibernateLazyInitializer().getImplementation();
}
return entity;
}
Is there a better way to do this, couldn't find a solution in the Hibernate forum, and didn't find the issue in Hibernate's JIRA.
Note: we cannot just use foo.getBar() (which will initialize the proxy properly) to get the Bar class object, because the session.get operation to fetch the Bar object does not know (or care for that matter) that the Bar class is also a lazy member of a Foo object that was just fetched. | java | hibernate | null | null | null | null | open | Lazy loading property and session.get problem

1. Create basic version of the 'user' model
2. Create an instance of this model - there needs to be at least one initial user in my system so that you can log in and start using it
3. Update the 'user' model to add a new field / column.
Now I'm using "validates_inclusion_of" on this new field/column. This worked fine on my initial development machine, which already had a database with these migrations applied. However, if I go to a fresh machine and run all the migrations, step 2 fails, because validates_inclusion_of fails, because the field from migration 3 hasn't been added to the model class yet.
As a workaround, I can comment out the "validates_..." line, run the migrations, and uncomment it, but that's not nice.
Better would be to re-order my migrations so the user creation (step 2) comes last, after all columns have been added.

Obviously doesn't work as I'm attempting to assign a string to an XML object. | javascript | flex | air | e4x | null | null | open | E4X : Assigning to root node
===
I am using Adobe Flex/Air here, but as far as I know this applies to all of JavaScript. I have come across this problem a few times, and there must be an easy solution out there!
Suppose I have the following XML (using e4x):
var xml:XML = <root><example>foo</example></root>
I can change the contents of the example node using the following code:
xml.example = "bar";
However, if I have this:
var xml:XML = <root>foo</root>
How do i change the contents of the root node?
xml = "bar";

- Custom XML pipeline description

Requirements:
- Must not depend on functionality only in the later versions of .NET (3+) since it's intended to be cross-platform and be used on top of managed kernels, meaning semi-limited .NET functionality.
- Must allow conditional pipeline building, so you can specify that certain command line options will correspond to certain elements and orders.

- Is there a way to get d:s:l to include data-insertion migrations?
- Should I not be using migrations at all to insert data this way?
- Should I not be pre-populating the database with data at all? Should I update the application code so that it handles the case where there are no users gracefully, and lets an initial user account be created live from within the application?
