(The other method, , can only rotate text clockwise 90 degrees).
However, in IE the rotated text looks like a badly scaled image on its side (comparison below).

Is there any way that Internet Explorer can rotate the text in a more elegant way (possibly Javascript/jQuery)? I've been Googling, but I can only find more references to this method...

for (int x = 0; x < largest.Rectangle.Width && edgePoints.Count == 0; x++) {
//top
for (int y = 0; y < largest.Rectangle.Height - 3 && edgePoints.Count == 0; y++) {
if (colorGrid[x, y].ToArgb() == Color.White.ToArgb() &&

colorGrid[x, y + 2].ToArgb() == Color.White.ToArgb() &&
colorGrid[x, y + 3].ToArgb() == Color.White.ToArgb()
) {
edgePoints.Add(new Point(x, y));
//g.DrawLine(new System.Drawing.Pen(Color.Orange), new Point(largest.Rectangle.X + x, largest.Rectangle.Y + y), new Point(largest.Rectangle.X + x, largest.Rectangle.Y + y + 3));
break;
}
}
//bottom
for (int y = largest.Rectangle.Height - 1; y > 3 && edgePoints.Count == 0; y++) {
if (colorGrid[x, y].ToArgb() == Color.White.ToArgb() &&

break;
}
}
}
```
Results in a fairly well defined outline, but if the and curves in anywhere, that edge is not detected. I.E., if I held my hand sideways, I'd get the edge of the top finger and bottom finger, but that's it.
What can I do to correct this and get a real edge?

Please see this screen shot ([full size](https://i.stack.imgur.com/b3yQX.png)):
For for every "received" and "expiry" box I want a jQuery datePicker box to appear and format as shown.
To test this I tried to create an example.
```
<link type="text/css" href="css/ui-lightness/jquery-ui-1.8.9.custom.css" rel="Stylesheet" />
<script type="text/javascript" src="js/jquery-1.4.4.min.js"></script>

$(function() {
$( "#datepicker" ).datepicker({ dateFormat: 'yy-mm-dd' });
$( "#datepicker2" ).datepicker({ dateFormat: 'yy-mm-dd' });
});
</script>
<style>
.ui-datepicker {
font-size: 80%;
}
</style>
<p>Date: <input id="datepicker" type="text" /></p>
<p>Date2: <input id="datepicker2" type="text" /></p>
```
Which works fine, but how do I get a date picker to come up for ANY textbox without having to repeat the JS so many times.
For say, 50 properties, there may be 200 input boxes on the page with a date needing to be filled in.
Here is some example code from the screen shot.
```
<tr>

<td>House Number</td>
<td>Address Line 1</td>
<td>Gas Expiry</td>
<td>Gas Received</td>
<td>Electric Expiry</td>
<td>Electric Received</td>
<td>Property Active</td>
<td>Update</td>

<td>4</td>
<td>6</td>
<td>East Street</td>
<td><input name="gas_expiry[4]" type="text" id="gas_expiry[4]" value="2011-08-03" /></td>
<td><input name="gas_received[4]" type="text" id="gas_received[4]" value="" /></td>
<td><input name="electric_expiry[4]" type="text" id="electric_expiry[4]" value="" /></td>
<td><input name="electric_received[4]" type="text" id="electric_received[4]" value="" /></td>

I'm creating a simple version of tic-tac-toe in 3D using the HTML5 `<canvas>` object. The first player uses the cross symbol, whereas the second player uses the circle symbol. The point is that I'm not sure how to put circular shapes into perspective.
Currently, the method I'm using is creating a regular polygon with as many angles as possible (to a certain extent, though) to fake a circle by drawing straight lines between those points. The coordinates of these points (angles) I have calculated using sine / cosine.
Using 6 angles:
Using 50 angles (looks like a circle well enough):
This works well, but it requires quite a lot of points to fake a circle nicely. Moreover, if I were to create a ball, I'd be in more trouble. The picture at Wikipedia, for example, shows that even with a great deal of points, it would still have a rather 'blocky' surface: [http://en.wikipedia.org/wiki/File:Sphere_wireframe.svg](http://en.wikipedia.org/wiki/File:Sphere_wireframe.svg)
I was wondering if there is any way to put a circle in perspective more effectively, perhaps without points, so as to be able to create a realistic looking circular shapes in a more practical way.
Thanks in advance for any suggestions.

I've profiled my Python program to death, and there is one function that is slowing everything down. It uses Python dictionaries heavily, so I may not have used them in the best way. If I can't get it running faster, I will have to re-write it in C++, so is there anyone who can help me optimise it in Python?
I hope I've given the right sort of explanation, and that you can make some sense of my code! Thanks in advance for any help.
This is the offending function, profiled using [line_profiler and kernprof](https://pythonhosted.org/line_profiler/). I'm running Python 2.7
I'm particularly puzzled by things like lines 363, 389 and 405, where an `if` statement with a comparison of two variables seems to take an inordinate amount of time.
I've considered using [NumPy](https://numpy.org/) (as it does sparse matrices) but I don't think it's appropriate because: (1) I'm not indexing my matrix using integers (I'm using object instances); and (2) I'm not storing simple data types in the matrix (I'm storing tuples of a float and an object instance).
But I'm willing to be persuaded about NumPy.
If anyone knows about NumPy's sparse matrix performance vs. Python's hash tables, I'd be interested.
Sorry I haven't given a simple example that you can run, but this function is tied up in a much larger project and I couldn't work out how to set up a simple example to test it, without giving you half of my code base!

This function maintains a sparse distance matrix representing the network distance (sum of edge weights on the shortest path) between nodes in a (very big) network. To work with the complete table and use the [Floyd-Warshall algorithm](https://en.wikipedia.org/wiki/Floyd%E2%80%93Warshall_algorithm) would be very slow. (I tried this first, and it was orders of magnitude slower than the current version.) So my code uses a sparse matrix to represent a thresholded version of the full distance matrix (any paths with a distance greater than 200 units are ignored). The network topolgy changes over time, so this distance matrix needs updating over time. To do this, I am using a rough implementation of a [distance-vector routing protocol](https://en.wikipedia.org/wiki/Distance-vector_routing_protocol): each node in the network knows the distance to each other node and the next node on the path. When a topology change happens, the node(s) associated with this change update their distance table(s) accordingly, and tell their immediate neighbours. The information spreads through the network by nodes sending their distance tables to their neighbours, who update their distance tables and spread them to their neighbours.
There is an object representing the distance matrix: `self.node_distances`. This is a dictionary mapping nodes to routing tables. A node is an object that I've defined. A routing table is a dictionary mapping nodes to tuples of (distance, next_node). Distance is the graph distance from node_a to node_b, and next_node is the neighbour of node_a that you must go to first, on the path between node_a and node_b. A next_node of None indicates that node_a and node_b are graph neighbours. For example, a sample of a distance matrix could be:
```
self.node_distances = { node_1 : { node_2 : (2.0, None),
node_3 : (5.7, node_2),
node_5 : (22.9, node_2) },
node_2 : { node_1 : (2.0, None),
node_3 : (3.7, None),
node_5 : (20.9, node_7)},
...etc...
```
Because of topology changes, two nodes that were far apart (or not connected at all) can become close. When this happens, entries are added to this matrix. Because of the thresholding, two nodes can become too far apart to care about. When this happens, entries are deleted from this matrix.
The `self.neighbours` matrix is similar to `self.node_distances`, but contains information about the direct links (edges) in the network. `self.neighbours` is continually being modified externally to this function, by the chemical reaction. This is where the network topology changes come from.
The actual function that I'm having problems with: `propagate_distances_node()` performs one step of the [distance-vector routing protocol](https://en.wikipedia.org/wiki/Distance-vector_routing_protocol). Given a node, `node_a`, the function makes sure that `node_a`'s neighbours are correctly in the distance matrix (topology changes). The function then sends `node_a`'s routing table to all of `node_a`'s immediate neighbours in the network. It integrates `node_a`'s routing table with each neighbour's own routing table.
In the rest of my program, the `propagate_distances_node()` function is called repeatedly, until the distance matrix converges. A set, `self.nodes_changed`, is maintained, of the nodes that have changed their routing table since they were last updated. On every iteration of my algorithm, a random subset of these nodes are chosen and `propagate_distances_node()` is called on them. This means the nodes spread their routing tables asynchronously and stochastically. This algorithm converges on the true distance matrix when the set `self.nodes_changed` becomes empty.
The "affinity distances" parts (`add_affinityDistance` and `del_affinityDistance`) are a cache of a (small) sub-matrix of the distance matrix, that is used by a different part of the program.
The reason I'm doing this is that I'm simulating computational analogues of chemicals participating in reactions, as part of my PhD. A "chemical" is a graph of "atoms" (nodes in the graph). Two chemicals binding together is simulated as their two graphs being joined by new edges. A chemical reaction happens (by a complicated process that isn't relevant here), changing the topology of the graph. But what happens in the reaction depends on how far apart the different atoms are that make up the chemicals. So for each atom in the simulation, I want to know which other atoms it is close to. A sparse, thresholded distance matrix is the most efficient way to store this information. Since the topology of the network changes as the reaction happens, I need to update the matrix. A [distance-vector routing protocol](https://en.wikipedia.org/wiki/Distance-vector_routing_protocol) is the fastest way I could come up with of doing this. I don't need a more compliacted routing protocol, because things like routing loops don't happen in my particular application (because of how my chemicals are structured). The reason I'm doing it stochastically is so that I can interleve the chemical reaction processes with the distance spreading, and simulate a chemical gradually changing shape over time as the reaction happens (rather than changing shape instantly).
The `self` in this function is an object representing a chemical. The nodes in `self.node_distances.keys()` are the atoms that make up the chemical. The nodes in `self.node_distances[node_x].keys()` are nodes from the chemical and potentially nodes from any chemicals that the chemical is bound to (and reacting with).
I tried replacing every instance of `node_x == node_y` with `node_x is node_y` (as per @Sven Marnach's comment), Sorry, I was doing the profiling wrong! I was using line_by_line, which (on my code) had far too much variance (that difference of ~90 seconds was all in the noise). When profiling it properly, `is` is detinitely faster than `==`. Using [CProfile](https://docs.python.org/3/library/profile.html), my code with `==` took 34.394s, but with `is`, it took 33.535s (which I can confirm is out of the noise).
Existing libraries
I'm unsure as to whether there will be an existing library that can do what I want, since my requirements are unusual:
I need to compute the shortest-path lengths between all pairs of nodes in a weighted, undirected graph. I only care about path lengths that are lower than a threshold value. After computing the path lengths, I make a small change to the network topology (adding or removing an edge), and then I want to re-compute the path lengths. My graphs are huge compared to the threshold value (from a given node, most of the graph is further away than the threshold), and so the topology changes don't affect most of the shortest-path lengths. This is why I am using the routing algorithm: because this spreads topology-change information through the graph structure, so I can stop spreading it when it's gone further than the threshold. i.e., I don't need to re-compute all the paths each time. I can use the previous path information (from before the topology change) to speed up the calculation. This is why I think my algorithm will be faster than any library implementations of shortest-path algorithms.
I've never seen routing algorithms used outside of actually routing packets through physical networks (but if anyone has, then I'd be interested).
[NetworkX](https://web.archive.org/web/20121115182146/http://networkx.lanl.gov:80/) was suggested by @Thomas K.
It has [lots of algorithms](https://web.archive.org/web/20150216223026/http://networkx.lanl.gov:80/reference/algorithms.shortest_paths.html) for calculating shortest paths.
It has an algorithm for computing the [all-pairs shortest path lengths](https://web.archive.org/web/20150306141810/http://networkx.lanl.gov:80/reference/generated/networkx.algorithms.shortest_paths.unweighted.all_pairs_shortest_path_length.html) with a cutoff (which is what I want), but it only works on unweighted graphs (mine are weighted).
Unfortunately, its [algorithms for weighted graphs](https://web.archive.org/web/20111114235558/http://networkx.lanl.gov:80/reference/generated/networkx.algorithms.shortest_paths.weighted.bellman_ford.html) don't allow the use of a cutoff (which might make them slow for my graphs). And none of its algorithms appear to support the use of pre-calculated paths on a very similar network (i.e. the routing stuff).
[igraph](https://web.archive.org/web/20220128234206/http://cneurocvs.rmki.kfki.hu/igraph/) is another graph library that I know of, but looking at [its documentation](https://web.archive.org/web/20191019073543/http://cneurocvs.rmki.kfki.hu/igraph/doc/python/index.html), I can't find anything about shortest-paths. But I might have missed it - its documentation doesn't seem very comprehensive.
[NumPy](https://numpy.org/) might be possible, thanks to @9000's comment. I can store my sparse matrix in a NumPy array if I assign a unique integer to each instance of my nodes. I can then index a NumPy array with integers instead of node instances. I will also need two NumPy arrays: one for the distances and one for the "next_node" references. This might be faster than using Python dictionaries (I don't know yet).
Does anyone know of any other libraries that might be useful?
Memory usage
I'm running Windows (XP), so here is some info about memory usage, from [Process Explorer](https://learn.microsoft.com/en-us/sysinternals/downloads/process-explorer). The CPU usage is at 50% because I have a dual-core machine.
My program doesn't run out of RAM and start hitting the swap. You can see that from the numbers, and from the IO graph not having any activity. The spikes on the IO graph are where the program prints to the screen to say how it's doing.
However, my program does keep using up more and more RAM over time, which is probably not a good thing (but it's not using up much RAM overall, which is why I didn't notice the increase until now).
And the distance between the spikes on the IO graph increases over time. This is bad - my program prints to the screen every 100,000 iterations, so that means that each iteration is taking longer to execute as time goes on... I've confirmed this by doing a long run of my program and measuring the time between print statements (the time between each 10,000 iterations of the program). This should be constant, but as you can see from the graph, it increases linearly... so something's up there. (The noise on this graph is because my program uses lots of random numbers, so the time for each iteration varies.)
After my program's been running for a long time, the memory usage looks like this (so it's definitely not running out of RAM):

4,901,460 | 1 | 4,901,725 | null | 2 | 3,584 | I would like to have a GUI setup like the diagram below.
The `JLayeredPane` should always be the same size, but the `JPanel` and the `JScrollPane` can change in size. I need the `JScrollPane` to be able to display the `JLayedPane` by clicking the arrows and what not if the `JPanel` and `JScrollPane` are not large enough to show the entire `JLayeredPane`.
The problem is that with the code below, the `JLayeredPane` always expands to fit the size of the `JScrollPane` and in the event that the `JScrollPane` is smaller than the `JLayeredPane`, it does not provide the scrolling ability.
Any Ideas on what is going on? Is there simpler code to achieve this?
Thanks
```
contentPanePanel = new javax.swing.JPanel();
contentPaneScollPane = new javax.swing.JScrollPane();
contentPane = new javax.swing.JLayeredPane();
contentPanePanel.setBorder(new javax.swing.border.LineBorder(new java.awt.Color(0, 0, 0), 1, true));
contentPane.setRequestFocusEnabled(false);
contentPane.setVerifyInputWhenFocusTarget(false);

4,901,578 | 1 | 4,902,145 | null | 2 | 1,020 | I have a view setup in the Views module that outputs an RSS feed of nodes. In the Fields section I have specified that I want the Title, Date and Body in the feed, but Views seems to ignore all but the title (and the link which I haven't specified to include). I know it's using the Views module because if I remove the title for each item or rename the entire feed it is reflected in the actual feed. I don't think there's any tpl files that are restricting the output either, but I don't know all the places to look. Does this sound familiar?

4,901,773 | 1 | 4,939,015 | null | 7 | 602 | I am pulling my hair out on this one.
We're just about done with the development of an overhaul to our site. As a last step, we're trying to wrap up all the glyphs and icons into a sprite. They're all transparent .png's so the sprite is too. It appears that if a background comes from a sptire, IE distorts it. If it comes from the original file, it does not. FF and Chrome are fine either way.
I am looking at the orignal image and the sprited version side-by-side with grids to see that the pixels are identical. I have counted the pixels in the sprite many times to ensure I'm using the right coordinates. My CSS looks like this:
```
XXbackground: url(sprite.png) no-repeat 0px -837px; /* lozRedRedSpacer */
background: url(lozRedRedSpacer.png) no-repeat;
```
The 'XX' lets me toggle back and forth. With the single-file version, it looks perfect: . The sprite-version looks like this: . It looks like it is 'squished' both vertically and horizontally. This does not happen in FF or Chrome.
Any ideas?
I was able to strip out most of the noise and post an example [here](http://stream.insigniagroup.com/temptest/index.htm). I've added notes to the example to describe my problem.
Thank you so much for taking the time to look at this!
We've since replaced these 'overlapped divider images' with CSS pseudo-classes that REALLY do overlap and the zooming issue seems to have gone away. Of course now we have new problems - IE8 gets the z-order wrong and IE7 doesn't understand psuedo-elements at all. But at least the markup is simpler and the zooming issue is gone.

4,902,306 | 1 | 4,902,446 | null | 1 | 3,912 | Hey, I am new to asp and I would like to ask you for some help. I built store with MvcMusicStore tutorial help. Now I want to add a View to manage orders which will display just OrderID (in Index View), then more info in Details View. Info will come from table which looks like this:
When I list OrderID, its multiplying because each product creates new record with the same OrderID in the table. Is there any way to display each Id just once?
Then I tried to display more info in Detaild View but I failed again. I used this code in Controller:
```
public ActionResult Details(int id)
{
var orderdetail = storeDB.OrderDetails.Single(a => a.Order.OrderId == id);
return View(orderdetail);
}
```
but obviously it wont work because only one element can be displayed. I also tried with foreach loop in Details.aspx but I was getting some IEnumerables-related error. Any advice is welcome, sorry for newbie question and bad English. Thank you.
Edit: Here is Controller's code for Index View (Product in my table equals Album in tutorial):
```
public ActionResult Index()
{
var manageorders = storeDB.OrderDetails
.Include("Product").Include("Order")
.ToList();
return View(manageorders);
}
```
And Details View code:
```
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/MasterPage.Master" Inherits="System.Web.Mvc.ViewPage<ss.Models.OrderDetail>" %>
```
Index
```
<div id="style3">manage orders</div>

The `python.lang` is a XML file containing all of the highlighting rules for python files. Ex:
```
<context id="special-variables" style-ref="special-variable">
<prefix>(?<![\w\.])</prefix>

<keyword>__debug__</keyword>

What I added to my `python.lang` file (if anyone's interested):
First off you need to add this line near the top where the styles are defined.
```
<style id="private-methods" _name="Private Methods" map-to="def:special-constant"/>
```
Then you'll add the Regex that [Carles provided in his answer](https://stackoverflow.com/questions/4902509/regex-to-match-double-underscores/4902883#4902883):
```
<context id="private-methods" style-ref="private-methods">

I'm building a tableView that has three sections.
I've got the first two working but the last one is a bit resistant.
My problem seems to involve trying to declare a variable inside a switch statement, actually a nested switch statement.
From what I've read that's not a good idea but in this case it seems like the only option.
The section in question dynamically accommodates the number of Alert objects that are associated with a particular piece of equipment. The Alerts are coming from Core Data and in place of "Date" and "Alert Message" I want to display the info from the Alert. I'm retrieving the relevant alerts using a NSFetchRequest. That returns an array of Alert objects that are sorted the way I want them. To display the proper information in the cellForRowAtIndexPath I've been trying to pull back that correct alert for the row using
```
Alert *alert = [allAlerts objectAtIndex:indexPath.row];
```
It seems I'm not allowed to declare a variable inside a switch statement. Any ideas how I can get around this? I'm going to have to do something similar in didSelectRowForIndexPath because I need to push a detail view when the cell is selected.
I've tried declaring the variable outside the switch statement but that's not going to work because the index.row can ask for an object at an index that doesn't exist in the array of Alert and that crashes the program.
The code in question is at the bottom of this method:
```

My intention is to make sure the colons are properly aligned as they are in Firefox and was just curious if the misalignment was due to the settings in the HTML or if it has more to do with how the browser renders the page.

I know it's ugly, just a note, this is an ASP.Net generated webpage and I'm setting the attributes of the HTML elements pro-grammatically from the code behind. I sorta inherited this and my employer wants to keep major changes to a minimum.
UPDATE 2:
When I adjust the inner table width I can get it to align in IE when set to 1377px. For Firefox, the sweet spot for alignment is 1260px.

} }, // search options

);
});
```
My Controller to be called somehow to load the categories:
```
public JsonResult GetCategories()
{
string test = "Will be a string contructed as needed";
//have to return something if there is an issue
return Json(test);
}
```
As i understand it dataUrl="GetCategories" of the colmodel descriptions editoptions would basically call this json action every time the add/edit button is pressed. I am hoping that somebody has an example of how to incorporate this so that it only occurs on page load.

This will produce something that looks like this in all modern browsers:
Now I know this is the standards-compliant behavior (as I knew before, but reconfirmed in [this post](https://stackoverflow.com/questions/4698054/css-does-the-width-include-the-padding), and I also know that if I include this code in the inner CSS declaration:
```
box-sizing:border-box;
-moz-box-sizing:border-box;
-webkit-box-sizing:border-box
```
...it will adopt the "border-box" model and get the behavior that seems more intuitive to me, but I just found myself trying to logically justify the reasoning behind why this is the way it is and I was unable to do it.
It seems (on the surface of things) more logical to me for the inner box to always fill the container to exactly 100% of the container's width, regardless of the padding or border of the inner box. I run into this problem all the time when I'm trying to set the width of a textarea to 100% that has a border or something like a 4px interior padding...the textarea will always overflow the container.
So my question is...what is the logic behind setting the default behavior to ignore the border and padding of an element when setting its width?

4,903,686 | 1 | 4,905,470 | null | 1 | 1,213 | I want to ensure that my list images (i.e., bullet symbols for unordered lists and numbers/letters/etc. for ordered lists) never truncate on the left, regardless of the font size they use. This seems to be an issue for WebKit-based browsers and I'm not sure of a decent workaround.
For example, the following piece of HTML displays improperly with Chrome 8/9:
```
<html>
<body>
<ol style="font-size: 48px;">
<li>one</li>
<li>two</li>
<li>three</li>
</ol>
</body>
</html>
```
The same piece of HTML displays properly (i.e., it doesn't truncate on the left) in Internet Explorer 8.
Two (undesirable) workarounds I've discovered are:
1. Specify list-style-position: inside; on the list. This forces the list image to flow with the content, but it makes for a non-standard/messy look, IMO.

4,903,771 | 1 | 4,904,167 | null | 0 | 1,301 | I'm working on generating a PHP/MySQL report that compares current and last year's sales data for a list of retail stores.
All of the data comes in fine from the SQL database. The sticking point is that the report needs to show how the stores are ranked this year, and what their ranking was last year.
Here's what the table should look like.
[http://i.stack.imgur.com/trEsO.png](https://i.stack.imgur.com/trEsO.png)
Here's the related part of my code.
```
$this->result = mysql_query($totalSalesQuery);
echo "<table>";
while($rows = mysql_fetch_object($this->result))
{
echo "<tr>";
echo "<td>" .$rows->store . "</td">;
// RANK COLUMN WOULD GO HERE
echo "<td>" . $rows->CurrentSales. "<td>";
// LAST YEAR'S RANK WOULD GO HERE
echo "<td>" . $rows->LastYrSales . "<td>";
echo "<td>" . ($rows->CurrentSales - $rows->LastYrSales)/$rows->LastYrSales) . "<td>";
echo "</tr>";
}
echo "</table>";
```
Is there a good way to use arrays to represent the columns? And then sort the arrays based on the different value?
Also, has anyone found any brilliant ways to total and average the columns and append that to the table?

I'm using their jquery player to place a widget on my new site, as you can see on the top right:
The problem is, the waveform Souncloud provides is a one colour only deal:
I know I can change things using PHPs GD library, and I've done this successfully with a test image on my server using this code:
[http://php.net/manual/en/function.imagefilter.php](http://php.net/manual/en/function.imagefilter.php)
(Search for "IMG_FILTER_BRIGHTNESS")
```
<?php
$im = imagecreatefrompng('hello.png');
if($im && imagefilter($im, IMG_FILTER_BRIGHTNESS, -255))
{
echo 'Image brightness changed.';
imagepng($im, 'hello.png');
imagedestroy($im);
}
else
{
echo 'Image brightness change failed.';
}
?>
```
It works perfectly! BUT
It changes the actual image on my server! Pretty cool, but not possible...
Obviously I cant change the image on Soundcloud's server (all the data, images, music comes from there API)
So What I'm looking for is a way were I can change the colour of the PNG client side, on the fly. I have a lot of tracks on there, so basically each time the user clicks next or previous, the waveform loads in and before it does it needs to change that image's colour :-?
Is this possible?

4,904,308 | 1 | 4,904,330 | null | 3 | 4,575 | I'm trying to make an arkanoid-like game, and now I'm facing a problem with the collisions. As usual, the bricks are rectangles (in my case, squares) and the ball is a circle, so it's all about axis aligned bounding boxes.
So far, I've got the trivial collision detection algorithm, but I need to know what side of each brick the ball hits. For example:
So far I have an algorithm that checks whether each side has been hit:
```
up = left = right = down = 0;
if(mouse.left < brick.left && brick.left < mouse.right && mouse.right < brick.right){
left = 1;
}
if(brick.left < mouse.left && mouse.left < brick.right && brick.right < mouse.right){
right = 1;
}
if(mouse.top < brick.top && brick.top < mouse.bottom && mouse.bottom < brick.bottom){
up = 1;
}
if(brick .top < mouse.top && mouse.top < brick.bottom && brick.bottom < mouse.bottom){
down = 1;
}
```
But in the collisions close to the corners, like the third in the image, two flags (for instance, left and down) are set to 1, so I don't know how to decide.
What is usually done in these cases?

4,906,911 | 1 | null | null | 1 | 116 | I am part of a studentproject and we are to develop a product for a company using Java EE. As "lead architect" in the project I am responsible for composing a good design which should be flexible for further extensions.
Background info: We are to develop a website with a drag and drop GUI with possibilites to connect data sources with data manipulations to perform on that specific data. The GUI should be generic and possible to integrate with upcoming products. This means that we cannot code to an implementation in the presentation layer. Instead we will use an interface to define what kind of data manipulations that are possible for all kinds of products. However, each product might also sport product specific data manipulations (thus extending the interface with more methods).
The problem I have with the scenario above is that I dont see how we could pass on these "product specific data manipulations" to the GUI and say that, in addition to the generic interface, we also possess these data manipulation actions...
Now I had a discussion with some of the more experienced programmers from the company and they told me that there is a common solution to this problem - more specifically known as the "Observer pattern". They draw something like `[1]` on the whiteboard and explained that it would be possible to "register" to a third party (getApplicationContext) that in turn could convey our product specific interface. This is a common problem to get rid of those nasty circular dependencies, they explained.
I have now had a look on the observer pattern and how it works and I still dont really get how I am supposed to solve the design problem. Could someone possibly try to explain how it would turn out in my specific scenario? I have no real problem understanding how it works with "subjects" and "observers".
Here is an UML diagram of the design where we are using a reference of the specific product. This is what is undesirable and something we would like to get around.
(maybe I got this all wrong...)
I am sorry but I cant change the picture to the correct one as I am a new user... Here is a link to an updated UML diagram:

So how do I declare the img for it to be showed in-front of that li-border?
And another fast question, can I declare so that the last li-element doesn't get that border-right, since it doesn't have a right-neighbour?

By accident, I seem to have dragged a new group I created out of my main project group:
When I try to move the group back into the project group, XCode crashes. When I try to delete the group by dragging it to the trash can, no such luck either. Is this because it's an iPhone project, and I somehow have messed up the entire directory of groups?

4,907,978 | 1 | null | null | 6 | 2,891 | I have 2000 sets of data which contain little over 1000 2D variables each. I'm looking to cluster these sets of data into anywhere from 20-100 clusters based on similarity. However, I'm having trouble coming up with a reliable method of comparing sets of data. I've tried a few (rather primitive) approaches and done loads of research, but I can't seem to find anything that fits what I need to do.
I've posted an image below of 3 sets of my data plotted. The data is bounded 0-1 in the y axis, and is within the ~0-0.10 range in the x axis (in practice, but could be greater then 0.10 in theory).
The shape and relative proportions of the data are probably the most important things to compare. However, the absolute locations of each data set are important as well. In other words, the closer the relative position of each individual point to the individual points of another dataset, the more similar they would be and then their absolute positions would need to be accounted for.
Green and red should be considered as very different, but push comes to shove, they should be more similar than blue and red.
I have tried to:
- - -
All of these have produced faulty results. The closest answer I could find in my research was "[Appropriate similarity metrics for multiple sets of 2D coordinates](https://stackoverflow.com/questions/2101467)". However, the answer given there suggests comparing the average distance among nearest neighbours from the centroid, which I don't think will work for me as the direction, is as important as the distance for my purposes.
I might add, that this will be used to generate data for the input of another program and will only be used sporadically (mainly to generate different sets of data with different numbers of clusters), so semi time consuming algorithms are not out of the question.

Unfortunately that image returns
```
ZIJZHZI
```
I think the resolution is too low and that is causing problems. I've tried magnifying the image, and cropping it down to individual characters, but neither of these provide much improvement. Is there anything else I should consider doing, preferably something that could be done using the Python Imaging Library? Or should I just give up/train tesseract.
For what it's worth, the PIL has the following built in filters:
> BLUR, CONTOUR, DETAIL, EDGE_ENHANCE,
EDGE_ENHANCE_MORE, EMBOSS, FIND_EDGES,
SMOOTH, SMOOTH_MORE, and SHARPEN

4,909,511 | 1 | 4,919,733 | null | 6 | 1,122 | I am posting my Stack Overflow problem on StackOverflow.com. Irony at its best!
Anyways. I am calling this procedure on my SkypeReply event handler, which gets fired a lot:
```
Procedure OnCategoryRename;
Var
CategoryID : Integer;
sCtgName : String;
Begin
if (AnsiContainsStr(pCommand.Reply,'GROUP')) and (AnsiContainsStr(pCommand.Reply,'DISPLAYNAME')) then
begin
sCtgName := pCommand.Reply;
Delete(sCtgName,1,Pos('GROUP',sCtgName)+5);
CategoryID := StrToInt(Trim(LeftStr(sCtgName,Pos(' ',sCtgName))));
sCtgName := GetCategoryByID(CategoryID).DisplayName; // Removing THIS line does not produce a Stack Overflow!
ShowMessage(sCtgName);
end;
```
The idea of this is to loop thru my list of Skype Groups, to see what group has been renamed. AFAIK thats of no importance, as my S.O has been traced to appear
```
Function GetCategoryByID(ID : Integer):IGroup;
Var
I : Integer;
Category : IGroup;
Begin
// Make the default result nil
Result := nil;
// Loop thru the CUSTOM CATEGORIES of the ONLY SKYPE CONTROL used in this project
// (which 100% positive IS attached ;) )
for I := 1 to frmMain.Skype.CustomGroups.Count do
Begin
// The Category Variable
Category := frmMain.Skype.CustomGroups.Item[I];
// If the current category ID returned by the loop matches the passed ID
if Category.Id = ID then
begin
// Return the Category as Result (IGroup)
Result := Category;
// Exit the function.
Exit;
end;
End;
End;
```
When I set a breakpoint at Result := Category; and Single Step thru, those 2 lines get executed over and over, right after each other!
And when I comment out the `sCtgName := GetCategoryByID(CategoryID).DisplayName;` in the first code snippet, there is no Overflow, the message gets shown that one time it is supposed to. However, the `GetCategoryByID` is a function I wrote, and I wrote one similar, too, which works just fine (GetCategoryByName), so I don't get why it decided to repeat the
```
// Return the Category as Result (IGroup)
Result := Category;
// Exit the function.
Exit;
```
over and over again.

4,909,552 | 1 | 4,909,557 | null | 1 | 1,034 | I'm trying to learn ASP.NET MVC, so I did as test project this where I want to display in Index a list of cities and when you click on city to see the properties in those cities.
Then I did some changes in global.asax in order to come up with nice URLs:
```
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Home-Browse",
"Accommodation-{city}",
new { controller = "Home", action = "Browse", city = "" });
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
```
So now after I see the list of cities and I click one I get a URL like: `/Accommodation-Amsterdam`
My problem is that I don't know how to do the inner join in order to tell the controller to show me the properties in the area selected. (I told you I'm just learning this)
My home controller:
```
using System;
using System.Collections.Generic;

using accomm2.Models;

{

return View();
}

{
//ViewData.Model = _db.Properties.ToList();
var properties = from c in _db.Cities
from p in c.Properties
where c.CityId == CityId
select c;
return View(properties.ToList());
}
}
}

Could somebody help me with my Linq query or at least direct me to the right way?

I'm just not getting how to set up a plist to store my data to match my model. Can anyone give me some advise please?
ADDITION:
(here is how I think I need to setup the plist - the data model is simply the three variables initializing my level (above). If you look at my current plist it might be more clear how it is setup, but each level is comprised of: a level number, a level speed, and an array of numbers denoting the required sequence for that level.)
Now, if I do have this setup correctly how do I load the values into my program?

4,912,046 | 1 | 4,912,656 | null | 3 | 978 | I have an array:
```
array([[ 4, 10],

[ 6, 8],
[ 3, 6],
[ 9, 7],
[ 2, 11],
[ 9, 5],
[ 8, 1]])
```
I want a method by which to order the value pairs so that as many as possible pairwise 2-element sets have a common value. This is an example of the desired ordered array:
```
array([[ 4, 10],
[ 4, 2],
[ 2, 11],
[ 5, 11],
[ 9, 5],
[ 9, 7],
[ 0, 7], #note the gap here:
[ 8, 1],
[ 6, 8],
[ 3, 6]])
```
Several conditions are true about these arrays. There are no duplicate pairs (ie: [1,0] nor [0,1] will appear elsewhere in the array if [0,1] already exists). No pair has the same value (ie: [1,1] will not exist). No pair will have more than two matches (iow: no value exists more than twice in the entire array.) but a pair can have as few as zero matches (note in the above array the gap across which there is no match).
Obviously, I can create every permutation of the array, but this seems brutish. I think there might be some way of cutting the deck and re-stacking in a logical way such that it becomes sorted in a small number of cuts. But before I go down that road, I want to: 1) Be sure that there is no `numpy` or `collections` function that already does this. 2) Know that there is no tricky-genius way to use numpy `.sort()` (or similar) to do it. 3) Find whether this is a common task and there is algorithm that does this. ("Oh, that's the Blumen-Funke algorithm!")
Here is some code that generates shuffled test arrays and checks sorted arrays:

## Results:
Thank you so much for all your help. Sven's solution was about 20% faster than Paul's and happily, they both run in linear time, Doug's answer did not solve the problem. There was a high, but also largely linear dependence of performance on the number of "breaks" or "gaps" in the input data. See the plot below. The 10,000 magnitude axis is N. the 0.5 axis is the percentage of breaks. the z axis is performance in seconds.
Thanks again!

4,913,170 | 1 | 4,913,221 | null | 1 | 315 | I'm trying to create a spectral image with a constant grey-scale value for every row. I've written some fantastically slow code that basically tries 1000 different variation between black and white for a given hue and it finds the one whose grey-scale value most closely approximates the target value, resulting in the following image:
On my laptop screen (HP) there is a very noticeable 'dip' near the blue peak, where blue pixels near the bottom of the image appear much brighter than the neighbouring purple and cyan pixels. On my second screen (Acer, which has far superior colour display) the dip is smaller, but still there.
I use the following function to compute the grey-scale approximation of a colour:
```
Math.Abs(targetGrey - (0.2989 * R + 0.5870 * G + 0.1140 * B))
```
when I convert the image to grey-scale using Paint.NET, I get a perfect black to white gradient, so that part of the code at least works.
So, question: Is this purely an artefact of the display qualities of my screens? Or can the above mentioned grey-scale algorithm be improved upon to give a visually more consistent result?
---
EDIT: The problem seems to be mostly monitor calibration. Not, I repeat not, a problem with the code.

4,913,168 | 1 | 4,977,103 | null | 0 | 738 | I have an `UIViewController` that has two UIViews inside, whose layout (set in Interface Builder) is something like this (the magenta colored view is the UIViewController default view):
and I added the main view to a root view obtaining this effect (by not showing the darker view placing its `frame` at the bottom):
Now when the device rotates, what I obtain is this:
whereas I'd like to still hide the darker view.
This is the code I use to hide it when it appears (I use it in the `viewDidLoad` method):
```
- (void)hideAll:(float)time{
CGRect hiddenFrame = CGRectMake(0, 1024, self.view.frame.size.width, self.view.frame.size.height);
[self.view setFrame:hiddenFrame];
[self.view setNeedsDisplay];
}
```
and it appears to work, but when I call a variant of it when rotating (in `willRotateToInterfaceOrientation:duration:`), nothing happens:
```
CGRect hiddenFrame = CGRectMake(0, 748, self.view.frame.size.width, self.view.frame.size.height);
[self.view setFrame:hiddenFrame];
[self.view setNeedsDisplay];
```
What am I missing? have I to set some other view property in Interface Builder?
It seems to me that the coordinate system does not change after the device has been rotated (ie the origin set in the upper-left corner in portrait mode will become the upper-right after a clockwise rotation in landscape mode)

4,913,259 | 1 | 4,913,603 | null | 1 | 325 | I'll try to explain this as best as i can, but i appologize if it gets too confusing - I've been stuck on this problem for many hours now.
In my application i have a search screen where the user will be able to select a bunch of criterias to perform the search by. Some of these criterias consists of fairly long lists of values to choose from and therefor i want a tableview on my searchscreen which have 4 rows - Each row representing a criteria that the user can set.
Once the user clicks on a row i want to push a new window in my navigationcontroller which consists of a new table containing the selectable values for that criteria - Once the user clicks on one of these rows on the new window, i want the selected value to be sent back to my main searchscreen and pop back to my search screen.
What would be the best way to do this?
My searchscreen is called SearchViewController and is contained in a navigationController.
SearchViewController contains two sliders and a tableView with 4 rows called "Searchtype", "Property type", "Salestype", "Area" and a searchbutton. If the user clicks on "Searchtype" then i want a new view to be pushed in the navigationController which should contain a new tableView with a bunch of rows representing different possible values for the "Searchtype" criteria - The same goes for all 4 rows in SearchViewController.
When the user clicks on one of the value rows in the newly pushed tableView i want that tableView to be popped away and the selected value sent back to the SearchViewController allowing the user to either select more criterias or push the search button to actually perform a search based on the selected criterias.
But i can't figure out the best way to do this?
I really appreciate any help i can get - I'm going nuts trying to figure this out :)
Btw. i don't use Interface Builder - All UI elements are coded manually.

I'm looking to inscribe a rectangle inside another (arbitrary) quad with the inscribed quad having the largest height and width possible. Since I think the algorithm will be similar, I'm looking to see if I can do this with a circle as well.
To be more clear hear is what I mean by the bounding quadrilateral as an example.
Here are 2 examples of the inscribed maximization I'm trying to achieve:
I have done some preliminary searching but have not found anything definitive. It seems that some form of dynamic programming could be the solution. It seems that this should be a linear optimization problem that should be more common than I have found, and perhaps I'm searching for the wrong terms.
For the inscribed square assume that we know a target w/h ratio we are looking for (e.g. 4:3). For the quad, assume that the sides will not cross and that it will be concave (if that simplifies the calculation).
