To demonstrate what I mean, if I wanted to have a User interface and a User implementation I'd have two choices in Java:
>1. Class = User, Interface = UserInterface
2. Class = UserImpl, Interface = User
Where in most languages:
>Class = User, Interface = IUser
Now, you might argue that you could always pick a most descriptive name for the user implementation and the problem goes away, but Java's pushing a POJO approach to things and most IOC containers use DynamicProxies extensively. These two things together mean that you'll have lots of interfaces with a single POJO implementation.
So, I guess my question boils down to: **"Is it worth following the broader Interface naming convention especially in light of where Java Frameworks seem to be heading?"** | java | naming-conventions | null | null | null | 04/19/2012 20:06:03 | not constructive | Interface naming in Java

1. When menu is open and you click elsewhere, menu closes.
2. When menu is open and you click elsewhere, nothing else happens.
I've got the first part down just fine. But when I click elsewhere, other events can occur. For instance, lets say I have button, A, which performs some action, B. Currently, if the JPopupMenu is open, and I click A, the JPopupMenu closes and B is performed. I would prefer that JPopupMenu close and B NOT be performed. Is this possible?

thanks | c | null | null | null | null | 04/24/2011 11:10:11 | not a real question | any other site(s) like this one?
===
this site is extremely cool ( http://www.gsp.com/cgi-bin/man.cgi?section=3&topic=strncpy ) but a bit unformatted, it shows many (and this means a lot) of C functions with params , example etc. the prototype example of the function is very bad anyway. do you know other sites as complete or more than this one? i recall there's one site with a dice icon that has many C functions.

To be able to read the specified url in my bean I bind it to the h:outputText from my facelet. Code from **RssReaderBean** bean:
private HtmlOutputText text;
public HtmlOutputText getText() {
return text;
}
public void setText(final HtmlOutputText text) {
this.text = text;
}
and the method which takes the url and returns the list:

try {
final URL u = new URL((String) text.getAttributes().get("url"));
///read the rss feed and prepare the result, this code works good so its not required here
}

Each group consists of around 20 observations. In total I look at around a 1000 variables.
I created a linear model using the lm function in R including 2 covariates. After that
I thought I include another covariate because doing a PCA plot earlier showed a slight effect on that covariate. However, after adding this covariate to the model 50% of the significant hits are now different. I was actually assuming that it would pretty much identical as the effect was hardly seen in the PCA.
Could it be that I have overfitted the model? Or is the effect simple just not shown in the PCA plot but is there?
I just compared the two models using anova(lm1, lm2) and the p-val is significant which I think means that the third covariate adds significant information to the model?
lm1 <- lm(var ~ factor_of_interest + cov1 + cov2)
lm2 <- lm(var ~ factor_of_interest + cov1 + cov2 + cov3)
anova(lm1, lm2)

return "model called #{@model.name}"
end
The above is all psudocode so sorry for any syntax/spelling mistakes, but the idea is I can have a condition which fetches the model and puts it into some local variable for the body to use, or do a halt with an error or something.
I am sure before/after would be a better way to do this if it can be done, however from what I have seen I would need to set that up per route, whereas with a condition I would only need to have it as an option on the request.
In ASP MVC you could do this sort of thing with filters, which is what I am ideally after, some way to configure certain routes (at the route definition) to do some work before hand and pass it into the calling block.

I am just wondering if it is possible to have a condition that passes information to the request body once it is complete, I doubt conditions can do it and are the right place even if they could, because it implies they are to do conditional logic, however the authorisation example also redirects so it has a blur of concerns... an example would be something like:
set(:get_model) { |body| { send_to_request_body(Model.new(body)) } }
get '/something', :get_model => request.body.data do
return "model called #{@model.name}"
end

I have to do a program in Java with the following characteristics:
"The system will create a guest list, which will be consulted by the doorman whenever it reaches a person. The porter guests can search by name or surname. When the event ends, you can extract statistical information about assistance the event. "
The identities or objects that I have identified are: User (a class can inherit Administrator and Porter or could create it separately), Events, Guests, a class for connection to the database and the graphics.
Well, the problem is that I really do not know what the use of classes Porter, Manager, Events and Guests will be. For all that I can do it directly with the database. I mean, if I have to insert a new guest, I would do is fill the textfield (name, surname, phone, etc.) in the program and when you click Insert button, for example, the event calls the method to insert into the database data obtained from those textfield, with getText (). The same when has to check a guest arrives and the same for delete or modify guests and events.

In many cases applications have no support for these extended attributes (proftpd for limiting operations via LDAP). But idea is, that according these settings, we will generate config file for Proftpd.
