javascript - Algorithms for positioning objects in a canvas -

-

Where can I find some algorithms for moving some objects in a clever way in the canvas? I am using Javascript (with Raphael SVG Library), but examples of other languages ​​(or pseudo-language) are welcome. Geometry is not my strong point =)

For example, 600x800 canvas is, and I want to place the size n in the smart ways 60x60, for example:
- One . Conditions with an algorithm for position meters concentric sections, but an alternate - algorithm for the location m condensed o offset with circles With the commodities frequency (the result may be like a chess)

And similar examples .. I'm just looking at some examples of work to be suited to my case. In advance, thank you =)

for circle:

Input: CenterPt (possibly 300,400 ), RadiusLargestCircle (possibly 270 to ensure your objects are RadiusDelta on all screens) 60 assures the objects are circles)

circles (calculate the number of RadiusLargestCircle -2 * RadiusDelta Overlapping objects) / RadiusDelta

For each cycle 

  RadCir = RadiusLargestCircle - (CircleNum * RadiusDelta)

(I Will end soon

But essentially the first object goes to centpt X = radiusLargestCircle, y = 0

the division object 2 * radius in the circumferance of the circle

For the number objects

using the parametric equation of the circle, the object on the last one to the x radius

the next circle

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
