{"routes":[],"status":"ZERO_RESULTS","Yf":{"origin":"36.4037460138417,-105.57447329101564","destination":"35.22918668520182,-101.84597704772949","optimizeWaypoints":false,"unitSystem":1,"region":"us","provideRouteAlternatives":false,"travelMode":"DRIVING"}}
If you copy those way points into Google Maps, it finds a route. This appears to only be happening on on destinations to Texas as near as I can tell, but I need to do more testing.
Is anyone else experiencing this? Thoughts on how to resolve? | google | routes | directions | null | null | 06/23/2012 17:08:22 | too localized | Google Directions Server returns no results for routes to Texas?

I have a web page that has a "Login" button in the top right corner of the screen. When the user clicks the button, I will display a CSS modal dialog box on the center of the screen that allows the user to type in their authentication information. The CSS dialog box is all set, there's just one piece missing:
I want to add an animation when the user clicks on the login button that shows the modal box "opening" from the Login button to the center of the screen to help draw the user's eye to where it is supposed to go next. The animation should feel similar to when a window is minimized to/unminimized from the Windows taskbar.
Can anyone point me to a JavaScript library that has this functionality? Thanks so much! | javascript | null | null | null | null | null | open | Animate a button in JavaScript to bring up a modal dialog box from the button to the center of the screen?

The problem is that the line "list:x:38:38:Mailing List Manager:/var/list:/bin/sh" is treated by the scanner as 3 different lines: 1) "list:x:38:38:Mailing" 2) "List" 3) "Manager..." When I type this out into a new file that I didn't get from linux, the Scanner parses it properly.
Is there something I'm not understanding about new lines in linux?
Obviously a work around is to parse it without using scanner, but it wouldn't be elegant. Does anyone know of an elegant way to do it?
Is there a way to convert the file into one that would work with Scanner?
Please let me know.

2. Some other objects has a "prototype" property, which is not in bold. What is that and when is good or not to use/implement it?
3. Most of functions are shown as "function()". But there are also some other functions which are displayed, for example, as "u(M)", "z()", "B(E)". Why they are different?

Which outputs notes to the output pane in Visual Studio 2005. When 'TRIAGE_MESG_AS_WARNING' is defined, Visual Studio will harvest these messages and list them as warnings in the Error List.

What do I need to do to get the output to show up in the Messages pane of the Error List? The format I have setup for messages in the above code looks like a message from other output, but does not get harvested in the same way.

, 'email' , , );
What should I put into the lat/lng so that it doesn't break the insert statement like this? Should it be nulls? That seems kind of inappropriate to put nulls, no? | 0 |

But I've run into a bug I can't seem to puzzle out. I'm new to parser combinators and FParsec seems to rely on me knowing Parsec, but I'm finding the parsec documentation inscrutable.
The rules of the task paper language are simple (I'm ignoring @tags for now)
- Projects end with a ':'
- Tasks are start with '-'
- Any other line of text is a plain text note on either the project or task
So the string "Project 1:\nSome note\nProject 2:" should return from parseFile as [ProjectName("Project 1");NoteText("Some note");ProjectName("Project 2")], but instead, I get [ProjectName("Project 1");ProjectName("Some note\nProject 2")]

What's happening though is that, depending on the size of the image, it seems there's a slight offset in the origin of where it selects the texture coordinates. The offset amount seems to be less than the size of a pixel & the output is is blurred combination of neighboring pixels.!
Here's an idea of what I'm describing. In this case I'd want to select the 6x5 green/white region but what OpenGL is rendering includes a slight pink tint to the top & left pixels.

I can fix it by adding an offset to the texture coordinates before passing them to glTexCoordPointer but the problem is that I have no way to calculate what the offset is and it seems different for different textures.
Pseudocode:
float uFactor = regionWidth / textureWidth; // For the example: 0.6f
float vFactor = regionHeight / textureHeight; // For the example: 0.5f
data[0].t[0] = 0.0f * uFactor;

Since javascript is a dynamic language, figuring out where is the unused code is quite hard and I believe my program has around 90% accuracy.

On average, it would involve somewhere in between 50K-150K rows. From these rows I need to extract the summation of Sum(X) as well as Count(X) based on five different criteria. There are two ways of going about it:
1. Write 10 different queries, each one designed to aggregate the data from column X using Sum() or Count(). Run each one and retrieve the result using SqlCommand.ExecuteScalar().
2. Create a custom object to contain all of the different parameters that would be needed to evaluate the different conditions. Run one query that will return all of the data needed to make up the superset containing all of the different conditional subsets, using SqlCommand.ExecuteDataReader(). Read each row from the DataReader into a new object, adding each one into a List<CustomObject> collection. One all data is retrieved, use Linq-to-Object to determine the different Sum() and Count() values needed based on different conditions.
I know that I could try each one out to see which is fastest, but I am interested in the community's advice on which one is likely to be faster. Assume Sql Server and Web Server each running on their own machines, each with sufficient memory.
Right now I am leaning towards option 1. Even though there are many more queries to the DB, the DB itself will do all of the aggregation work and very little data will pass in between the Sql Server and the Web Server. With option 2, there is only one query, but it will pass a very large amount of data to .Net, and then .Net will have to do all of the heavy lifting with regards to the aggregate functions (and though I don't have anything to base it on, I suspect that Sql Server is more efficient at running these types of big aggregate functions).
Any thoughts on which way to go (or a third option that I am missing)? | sql-server | aggregate | .net | asp.net | c# | null | open | Perform Data Analysis on Sql Server or in .Net?

I read [here](http://pubs.opengroup.org/onlinepubs/009604499/functions/system.html "About the perils of System!") that **system** has some perils. It is safe to use it in this context?

I am really struggling with the understanding of OAuth. For a project I am trying to create a consumer role that does not utilise tokens.
I have managed to create the required details in the code behind like so
string outUrl = "";
string querystring = "";
string consumerKey = "82ad8188-b949-eff8-c5b1-f801b74cfc89";
string consumerSecret = "c031956b-1916-d1f7-2cf9-aa52aaad4dfa";
Uri uri = new Uri("http://pebblepad.co.uk/sandbox/interop/oauth/login.aspx");
oAuthBase2 oAuth = new oAuthBase2();
string nonce = oAuth.GenerateNonce();
string timeStamp = oAuth.GenerateTimeStamp();
string sig = oAuth.GenerateSignature(uri, consumerKey, consumerSecret, string.Empty, string.Empty,
"POST", timeStamp, nonce, oAuthBase2.SignatureTypes.HMACSHA1, out outUrl,
out querystring);
From here I don't understand what to do next. I am not an experienced programmer and most examples I have found don't even include coding example.
Please help, I am in desperate need :( | 0 |

I would then like to swap out the images of the buttons when a user first hovers over the GridView row and then again when the user hovers over a specific button.
I can easily accomplish this hover functionality using CSS and image hyperlinks, however when using image hyperlinks, I am unable to raise any server-side events to handle editing the particular row.
In the past, I've used ImageButtons instead of image hyperlinks. I added the CommandName parameter to the ImageButtons and then handled the GridView RowCommand in code:
<asp:ImageButton ID="btnSelect" CommandName="select" runat="server" ImageUrl="~/images/iconSelect.png" />
In order to change the ImageButton image on hover, I used Javascript:
<asp:ImageButton ID="btnSelect" onmouseover="this.src='../images/iconSelectOver.png';" onmouseout="this.src='../images/iconSelect.png';" runat="server" ImageUrl="~/images/iconSelect.png" />
However, in this case, I need to also replace the ImageButton image when a user first hovers over the GridView row itself.
To sum up, when a user hovers over a GridView row, the ImageButtons on that row will all swap image1 for image2. Then when a user hovers over a specific ImageButton, its image will switch from image2 to image 3.
Thanks in advance for any suggestions you may have as to the best approach.

The reason I'm wondering is because I use LinqPad and in one section there are comments that say:
// Note: before delving into this section, make sure you've read the preceding two
// sections: Select and SelectMany. The Join operators are actually unnecessary
// in LINQ to SQL, and the equivalent of SQL inner and outer joins is most easily
// achieved in LINQ to SQL using Select/SelectMany and subqueries!
Yet, in other sections it clearly shows that joins are faster (at least for the examples given in LinqPad) and to me they are easier to visualize in my head.
Perhaps I'm misunderstanding since I'm only looking through the code samples and not the book, but I've seen other people recommend Select and SelectMany over Joins as well. | linq-to-sql | null | null | null | null | 05/04/2012 13:18:43 | not a real question | LinqToSQL Select and SelectMany vs Join
