I recently showed this to someone, asking for feedback on how it looked, and he concentrated on how sloppy the html was.
**My question is, is it better to have a clean, unadorned html at the very beginning of the load, and build out the code to make the magazine that allows for the swiping on the different devices and click-throughs for desktop versions?**
Sorry I don't have a demo handy, I'm trying several css frameworks to gain control over the typical adventurous "let's try this" coding cycle to make it easier to understand and update for the future (an integrated creation system online, with styles a creator can modify).

In the example I have set the left-clip to 30px to highlight the issue, normally this would be in multiples of 128px. When I set the left clip to 30px, it seems to add 30px left margin. Surely, I don't need to add a negative left margin to correct it?
I am a total newbie to `clip` as I have never really needed to use it, but now there is. My understanding of it is the same as a square cut out of a piece of paper. Adjusting the clip values will move the piece of paper around therefore changing the viewed image.

I never unit tested with php! | I am at a point in my learning about solid software development where I realize that the "pedal-to-the-medal code at light speed and pray for good results with no real plan" approach does not work.
I am seeking to replace my old (and admittedly not exactly great) ways with solid practices. I have never used unit testing before, and now on top of trying to learn pyramid (which is going well thanks to the thorough documentation) I am also trying to see how unit testing in general can benefit me (also in the future add integration testing, regression testing, etc.). I read this intro to nosetest http://ivory.idyll.org/articles/nose-intro.html, and (not to be flippant) I see that you can use unit tests to test regular expressions, and see `if a=1; b=1; now does a == b`. This is all I can see at this point. I do not need a framework for this. I can use a regular expression tester, and common sense to 'test'. If I'm going to use unit testing to see if two variables are equal, then wouldn't i have to create a test every time I create a variable and set it equal to something? The examples from the article just seem kind of arbitrary.
My mind is way open to learning the benefits of unit testing, but I want to know What are some practical applications of unit testing.
Bottom line: I have never used unit testing before, so please tell me why I am wrong, and should start using testing.

I need some help with my project.. I wish to develop a two player game to be played over the network (Intranet).
I want to develop a simple website with a few html pages for this.My ideas for the project run as follows:
1.People can log in from different systems and check who ever is online on the network currently.
the page also shows who is playing with whom.
2.If a person is interested in playing with a player who is currently online, he sends a request of which the other player is somehow notified( using a message or an alert on his profile page..)
3.If the player accepts the request, a game is started. This is exactly where I am clueless.. How can I make them play the game? I need to develop a turn based game with two players, eg chessboard.. how can I do this? The game has to be played live.. and it is time tracked.
i need your help with coding the above.. the other features i wish to include are:
4.The game could not be abruptly terminated by any one if the users.The request to terminate the game should be sent to the other player first and only if he accepts can the game be terminated.
5. Whoever wins the game would get a plus 10 on their credit and if he terminated he gets a minus 10. The credits remains constant even if he loses but the success percentage is reduced.
6.The player with highest winning percentage is projected as the player of the week on the home page and he can post a challenge to all others..
I only have an intermediate knowledge of core java and know the basics of Swing and Awt. I am not at all familiar with networking in java right now. I have 5 to 6 weeks of time for developing the project but I hope to learn the things before I start my project.
i would prefer to use a lan to illustrate the project and I know only java,jsp,oracle,html and bit of xml to develop my proj.
Also I wish to know if I can code this within 6 weeks, would it be too difficult or complicated? Please spare some time to tell me.
Please.. please.. I need your suggestions and help..

I had some time between projects and started to learn C#. I wanted to make simple things(in my opinion).
- to get a form window handle
- to call a function written in C++ and compiled as dll
- to populate a PropertyGrid at run time
- to use a form in another form(parent-child windows)
- to convert a byte array to a string
- to change build path
and much more things that I think are usual things when somebody creates an application.
With the help of stackoverflow members I managed to do almost all the things I wanted, but everything seems to be more complicated than in C++.
There are many syntax/IDE flaws:
- It does not convert any int value to bool(check for null for example is weird)
- Use of "out" when calling a function, the function was already defined using "out" keyword
- The sources must be in same folder(or sub-folder) as the project
- obj folder in same folder as the project
- When I double click on a source file the IDE opens Design instead of code
I don't want to put this language in a corner and forget about it. I want to know the good things about it. My first contact with C# let me the impression that I don't have freedom, that everything I must do requires more code that same thing in C++.
Can you help we with good/bad things of C# in comparison with C++?
Something simple like:
> C++ - converts int values to bool
> values -> check for NULL is simple

I think that in Java and C# world it is a rather accepted practice to generally have one module per class. I think this is a good rule to follow in Delphi too, because in Delphi private members aren't really private if you have more than one class in a unit.
So I was surprised to hear from two different senior (and probably more experienced than I am) programmers tell me I divide my code too much. One of them told me to not be shy about placing 5-6 classes in a unit.
Is there some issue with "one class per module" rule that I am not aware of? And is "5-6 classes per unit" a good recommendation?
I do not mean to take these rules as absolutes. Surely there can be situations when it is appropriate to do either way. I am asking about the general rule. | delphi | delphi-7 | null | null | null | 07/24/2012 02:51:00 | not constructive | How many classes per unit are advisable to have?

1. http://railscasts.com/episodes/235-omniauth-part-1?view=asciicast
2. http://railscasts.com/episodes/236-omniauth-part-2?view=asciicast
**Scenario:** A twitter user comes to my app. Clicks on the Twitter link to sign in and is taken to /auth/twitter. He allows my app on the twitter site and is redirected back to my app. He enters his email id on my site as that is mandatory. He uses the site and then signs out of my app. He then wants to log back in again. He clicks on the Twitter sign in icon again.
**My problem:** I expected that he would not have to authorize my app once again on the twitter site. But, that is not the case. This time again, twitter asks this user to authorize.
My code follows the railscasts exactly:
<routes.rb>
match '/auth/:provider/callback' => 'authentications#create'
class AuthenticationsController < ApplicationController
...
def create
omniauth = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
if authentication
flash[:notice] = "Signed in successfully."
sign_in_and_redirect(:user, authentication.user)
elsif current_user
current_user.authentications.create(:provider => omniauth['provider'], :uid => omniauth['uid'])
flash[:notice] = "Authentication successful."
redirect_to authentications_url
else
user = User.new
user.apply_omniauth(omniauth)
if user.save

sign_in_and_redirect(:user, user)
else
session[:omniauth] = omniauth.except('extra')
redirect_to new_user_registration_url
end
end
end
...
end

I have installed bonjour sdk in my system so the Unit Test for it is working fine in my machine.
But When we run on fresh machine it is crashing.The reason for this Bonjour is not installed on that system.This library is going to be used in Some application.
My assumption is to run this library we not run mDNResponder.exe and mdnsNSP.dll.
One way to solve the problem is install the Bonjour SDk manually.
I am wanted to do it programatically.Please help me do this.

So, for example, one user might enter the url `http://www.example.com`, a minimum of `90` hits, a maximum of `150` and a time until reset of `1 hour`. Every hour, a number will be chosen from between the two, and become the new hit amount for that hour. Once the the number of hits for `http://www.example.com` has been reached within an hour `http://www.example.com` will be removed from the list, until the next reset.
All in all, on a page load, at least 3-4 database queries are made at different points throughout.
**Here are my questions:**
Is this sustainable with large traffic amounts, say `2,500+` requests per hour without some kind of caching mechanism (which is almost impossible to build, because hit's need to be exact and updated on request, so I don't see how a cache could be built in this instance)?
What are the variables/factors that will determine whether or not this will be doable?
I realize my questions a little, "iffy", so please do ask clarification if you need it :)!

For 1:N-relationships: If I just swap a column ParentId (pointing "backwards" from target entity to source entity) to a Link (edge) in a separate table pointing from SourceId to TargetId. Would that qualify as a kind of graph-database right there?
A hierarchical structure is just a kind of graph where each node have only one incoming link (perhaps this could be limited to a link of a certain type/label?).
A graph database is a database where the relationships have been moved into a separate table where more information can be stored about each relationship.
A graph-database with a link-table would in some way replace the need for a middle-table for N:N-relationships. (BTW what is the correct name the kind of table used with a N:N-relationship?)
Using a separate Link-table consume more space but is faster and simpler to query.
If I choose to go with my idea for a SQL-graph-database for now, would it be easy to migrate to a complete graph-database later?
Please give some examples of what I would miss by not going all-in on a graph-database today? (not needed to get accept!) | c# | sql | relational-database | graph-databases | null | 07/19/2012 15:19:32 | not a real question | Basic graph-database in SQL?

Inside the Document class I have an NSMutableArray and an NSMutableIndexSet that are linked up with bindings to an NSArrayController.
The inspector panel is in a separate nib file, and I have two identical NSArrayControllers, one from the main document window, and one from the inspector panel, so that both can interact with the document. This is why I do a manual binding to the selectionIndexes, so that I don't get two separate selections with the two separate NSArrayControllers.
The inspector panel keeps track of which document is being inspected by a:
Document *inspectedDocument;
which is updated whenever the document is switched, or no document has focus at all. An NSObjectController is linked up to <code>inspectedDocument</code>, and the NSArrayController I mentioned before is linked up to that controller.
Now, my problem is that when the inspector panel is in place, and the <code>inspectedDocument</code> is changed, the selection indexes are reset. The problem goes away if I don't use the inspector panel, so I assume it is its NSArrayController that is issuing this reset. I don't have any controls that bind to the selection and could change it (such as a table view).
In the inspector panel's NSArrayController, if I have "Avoid Empty Selection" ticked, the selection resets to the first object, otherwise it resets to no selection, so it is definitely a legitimate resetting of the selection. Actually, I don't even want the inspector panel to ever be able to change the selection, so ideally I would like to establish a read-only binding for that NSArrayController's selection indexes.
**In short:**
The NSArrayController's selection is being reset whenever the parent NSObjectController changes what it's point at. How can I prevent this happening? | objective-c | cocoa | osx | cocoa-bindings | null | null | open | NSArrayController selection being reset

I have a Cocoa Document-based Application with an inspector panel that is shared between documents (modelled after the TextEdit source code that ships with xcode). Inside the Document class I have an NSMutableArray and an NSMutableIndexSet that are linked up with bindings to an NSArrayController.
The inspector panel is in a separate nib file, and I have two identical NSArrayControllers, one from the main document window, and one from the inspector panel, so that both can interact with the document. This is why I do a manual binding to the selectionIndexes, so that I don't get two separate selections with the two separate NSArrayControllers.
The inspector panel keeps track of which document is being inspected by a:
Document *inspectedDocument;
which is updated whenever the document is switched, or no document has focus at all. An NSObjectController is linked up to <code>inspectedDocument</code>, and the NSArrayController I mentioned before is linked up to that controller.
Now, my problem is that when the inspector panel is in place, and the <code>inspectedDocument</code> is changed, the selection indexes are reset. The problem goes away if I don't use the inspector panel, so I assume it is its NSArrayController that is issuing this reset. I don't have any controls that bind to the selection and could change it (such as a table view).

I also tried remove an item and re-inserting it with no result.
