Hi,
An interaction designer employed by the client I am currently working for produced some mock-ups, and now it is my job to determine the best way of implementing the charts included therein.
After looking at the options I am aware of and was able to find doing some simple Google searches, I have narrowed it down to using either , or , simply because from what I can see of their demos, they have certain features I believe I will need to get things done.
Here are the pictures from the mock-ups - ideally I need one piece of software that will cover all of these:

Any ideas or recommendations would be appreciated, I haven't used charting controls in , so I am at a bit of a loss and the client wants an estimate soon.
Thank you!

3,010,837 | 1 | 3,080,946 | null | 22 | 6,646 | Sampling uniformly at random from an n-dimensional unit simplex is the fancy way to say that you want n random numbers such that
- - -
In the n=2 case you want to sample uniformly from the segment of the line x+y=1 (ie, y=1-x) that is in the positive quadrant.
In the n=3 case you're sampling from the triangle-shaped part of the plane x+y+z=1 that is in the positive octant of R3:
(Image from [http://en.wikipedia.org/wiki/Simplex](http://en.wikipedia.org/wiki/Simplex).)
Note that picking n uniform random numbers and then normalizing them so they sum to one does not work. You end up with a bias towards less extreme numbers.
Similarly, picking n-1 uniform random numbers and then taking the nth to be one minus the sum of them also introduces bias.
Wikipedia gives two algorithms to do this correctly: [http://en.wikipedia.org/wiki/Simplex#Random_sampling](http://en.wikipedia.org/wiki/Simplex#Random_sampling)
(Though the second one currently claims to only be correct in practice, not in theory. I'm hoping to clean that up or clarify it when I understand this better. I initially stuck in a "WARNING: such-and-such paper claims the following is wrong" on that Wikipedia page and someone else turned it into the "works only in practice" caveat.)
Finally, the question:
What do you consider the best implementation of simplex sampling in Mathematica (preferably with empirical confirmation that it's correct)?

3,011,604 | 1 | null | null | 24 | 48,820 | I've really been struggling through this. New to Java/Android. I'm writing my first app and this is the first thing that has taken me longer than a couple days of searching to figure out. Here's the setup: It's a BAC calculator / drink counter:
A formula is used to calculate the BAC. Here's the forumla:
```
Bac = ((StandardDrinks / 2) * (GenderConstant / Weight)) - (0.017 * Hours);
```
So as you can see, being able to modify the gender and weight will produce more accurate and personalized results. So I have them as doubles:
```
double GenderConstant = 7.5; //9 for female
double Weight = 180;
```
To change these variables I would like the person to be able to go into the settings and choose different values. I have these things set up, but not linked to the variables shown above because I cannot for the life of me figure out how. Here they are:
I press the menu button and this pops up. Great. I'll click Settings.
Now the preferences pops up. Here is my preferences.xml:
```
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="Personal Settings">
<ListPreference
android:title="Gender"
android:summary="Verify or deny the presence of a Y chromosome."
android:key="genderPref"
android:defaultValue="male"
android:entries="@array/genderArray"
android:entryValues="@array/genderValues" />
<ListPreference
android:title="Weight"
android:summary="How much the planet pulls on you, in pounds."
android:key="weightPref"
android:defaultValue="180"
android:entries="@array/weightArray"
android:entryValues="@array/weightValues" />
</PreferenceCategory>

android:summary="The volume of your beer, in ounces."
android:key="beerPref"

<ListPreference

android:summary="The volume of your shot, in ounces."
android:key="shotPref"

android:entryValues="@array/shotValues" />

android:summary="The volume of your wine, in ounces."
android:key="winePref"
android:defaultValue="5"
android:entries="@array/wineArray"
android:entryValues="@array/wineValues" />
</PreferenceCategory>
</PreferenceScreen>
```
Onward to the weight ListPreference:
And that shows up. The values are stored as string-arrays in res/values/arrays.xml. Here's a sample, of just the weight ones:
```
<string-array name="weightArray">
<item>120 lbs</item>
<item>150 lbs</item>
<item>180 lbs</item>
<item>210 lbs</item>
<item>240 lbs</item>
<item>270 lbs</item>
</string-array>
<string-array name="weightValues">
<item>120</item>
<item>150</item>
<item>180</item>
<item>210</item>
<item>240</item>
<item>270</item>
</string-array>
```
This is basically as far as I've gotten. I can click a value, sure, but it doesn't change the formula because it's not linked with the doubles I created in DrinkingBuddy.java. All of the stuff displayed in the settings are just empty shells for now, including the spinner on the main layout (the default time is just set to 1 hour)
I did create a Preferences.java and have tried implementing various combinations of code found in tutorials and resources around the web, but to no avail. Here it is anyway, filled with failed attempts to make beerPref (the settings option to change how many ounces in the beer) correlate with a variable in my main class:
```
package com.dantoth.drinkingbuddy;
import android.app.Activity;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.Preference;
import android.preference.PreferenceActivity;
import android.preference.Preference.OnPreferenceClickListener;
public class Preferences extends PreferenceActivity {
public static final String PREF_BEER_SIZE = "PREF_BEER_SIZE";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
//Get the custom preference
Preference beerPref = (Preference) findPreference("beerPref");
beerPref.setOnPreferenceClickListener(new OnPreferenceClickListener() {
public boolean onPreferenceClick(Preference preference) {
SharedPreferences customSharedPreference = getSharedPreferences("myCustomSharedPrefs", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = customSharedPreference.edit();
editor.commit();
return true;
}}
);}
}
```
A full on tutorial and sample code would be AWESOME as I've yet to find any reliable guides out there.

WaterSupply waterSupply; // only one in the entire application

Rooms rooms;
Hotel hotel(staff, rooms, powerGrid, waterSupply);

It will always be passed an `IEnumerable<Topping>`, and output a multitude of checkboxes. There are lots... maybe 40 in all (yes, that might smell). A-OK so far.
The question is around how to include the user's choices on the Details and Update views. From the datastore, we've got a `List<ChosenTopping>`. The goal is to have each checkbox set to true for each chosen topping. What's the easiest to read, or most maintainable way to achieve this?
1. Create a ViewModel with the List and List. Write out the checkboxes as per normal. While writing each, check whether the ToppingID exists in the list of ChosenTopping.
2. Create a new ViewModel that's a hybrid of both. Perhaps call it DisplayTopping or similar. It would have property ID, Name and IsUserChosen. The respective controller methods for Create, Update, and Details would have to create this new collection with respect to the user's choices as they see fit. The Create controller method would basically set all to false so that it appears to be a blank slate.
The real application isn't pizza, and the organization is a bit different from the fakeshot, but the concept is the same.

My problem is that some commands (or messages, or whatever) get stuck in the mini-buffer so that when I type a new command it appears there really quickly, and then the mini-buffer is back to the stubborn command. Some commands seem to be chosen, and after using lots of commands something else gets stuck there, but there is always something being shown that I don't want to see. I tried typing C-g lots of times to see if it would quit, but that does not work.
This is a picture of what I have now:
It does not matter what I do, that bit
> Label: hl-line
will not leave. It does leave momentarily when a new command is typed, but it goes back. I don't like it, it is confusing, and I would much rather see there the last used command.
I did check the customisation options for the mini-buffer (the bottom part of it can be seen in my picture), but I found nothing that seemed to be what I was looking for.
Any ideas?

Here's the scenario:
I've got a table called MarketDataCurrent (MDC) that has live updating stock prices.
I've got one process called 'LiveFeed' which reads prices streaming from the wire, queues up inserts, and uses a 'bulk upload to temp table then insert/update to MDC table.' (BulkUpsert)
I've got another process which then reads this data, computes other data, and then saves the results back into the same table, using a similar BulkUpsert stored proc.
Thirdly, there are a multitude of users running a C# Gui polling the MDC table and reading updates from it.
Now, during the day when the data is changing rapidly, things run pretty smoothly, but then, after market hours, we've recently started seeing an increasing number of Deadlock exceptions coming out of the database, nowadays we see 10-20 a day. The imporant thing to note here is that these happen when the values are NOT changing.
Here's all the relevant info:
Table Def:
```
CREATE TABLE [dbo].[MarketDataCurrent](
[MDID] [int] NOT NULL,
[LastUpdate] [datetime] NOT NULL,
[Value] [float] NOT NULL,
[Source] [varchar](20) NULL,
CONSTRAINT [PK_MarketDataCurrent] PRIMARY KEY CLUSTERED
(
[MDID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
```
-
I've got a Sql Profiler Trace Running, catching the deadlocks, and here's what all the graphs look like.
Process 258 is called the following 'BulkUpsert' stored proc, repeatedly, while 73 is calling the next one:
```
ALTER proc [dbo].[MarketDataCurrent_BulkUpload]
@updateTime datetime,
@source varchar(10)
as
begin transaction
update c with (rowlock) set LastUpdate = getdate(), Value = t.Value, Source = @source
from MarketDataCurrent c INNER JOIN #MDTUP t ON c.MDID = t.mdid
where c.lastUpdate < @updateTime
and c.mdid not in (select mdid from MarketData where LiveFeedTicker is not null and PriceSource like 'LiveFeed.%')
and c.value <> t.value
insert into MarketDataCurrent
with (rowlock)
select MDID, getdate(), Value, @source from #MDTUP
where mdid not in (select mdid from MarketDataCurrent with (nolock))
and mdid not in (select mdid from MarketData where LiveFeedTicker is not null and PriceSource like 'LiveFeed.%')
commit
```
And the other one:
```
ALTER PROCEDURE [dbo].[MarketDataCurrent_LiveFeedUpload]
AS
begin transaction
-- Update existing mdid
UPDATE c WITH (ROWLOCK) SET LastUpdate = t.LastUpdate, Value = t.Value, Source = t.Source
FROM MarketDataCurrent c INNER JOIN #TEMPTABLE2 t ON c.MDID = t.mdid;
-- Insert new MDID
INSERT INTO MarketDataCurrent with (ROWLOCK) SELECT * FROM #TEMPTABLE2
WHERE MDID NOT IN (SELECT MDID FROM MarketDataCurrent with (NOLOCK))
-- Clean up the temp table
DELETE #TEMPTABLE2
commit
```
To clarify, those Temp Tables are being created by the C# code on the same connection and are populated using the C# SqlBulkCopy class.
To me it looks like it's deadlocking on the PK of the table, so I tried removing that PK and switching to a Unique Constraint instead but that increased the number of deadlocks 10-fold.
I'm totally lost as to what to do about this situation and am open to just about any suggestion.
HELP!!

3,023,870 | 1 | 3,298,641 | null | 0 | 160 | I have a rather complicated Binding situation. I have a solution that I created in windows forms for this back in VS2005, but now I am recreating the control using wpf, but I am not doing it in exactly the same way I had done it before.
I have a listbox control that has the following DataTemplate:
```
<DataTemplate>
<Border CornerRadius="5" BorderBrush="Black" BorderThickness="1">
<StackPanel>
<TextBlock x:Name="TaxonomyCode" Margin="2" FontWeight="Bold"
FontSize="12">
<TextBlock.Text>
<MultiBinding StringFormat="{}{0}{1}{2}X">
<Binding Path="TaxonomyTypeID" />
<Binding Path="TaxonomyClassificationID" />
<Binding Path="TaxonomySpecializationID" />
</MultiBinding>
</TextBlock.Text>
</TextBlock>
<TextBlock Margin="2"
Text="{Binding ElementName=TaxonomyCode,Path=Text,Converter={StaticResource TaxonomyCodeToDescriptionConverter}}" />
</StackPanel>
</Border>
</DataTemplate>
```
Below that I have 3 listboxes that list the actual Taxonomy Hierarchies using properties on my ViewModel...
```
<ListBox
Grid.Column="0" Grid.Row="1"
ItemsSource="{Binding TaxonomyTypeLUT}"
DisplayMemberPath="IDDescription"
SelectedItem="{Binding Path=SelectedTaxonomyType}" />
<ListBox
Grid.Column="1" Grid.Row="1"
ItemsSource="{Binding SelectedTaxonomyType.TaxonomyClassifications}"
DisplayMemberPath="IDDescription"
SelectedItem="{Binding Path=SelectedTaxonomyClassification}" />
<ListBox
Grid.Column="2" Grid.Row="1"
ItemsSource="{Binding SelectedTaxonomyClassification.TaxonomySpecializations}"
DisplayMemberPath="IDDescription"
SelectedItem="{Binding SelectedTaxonomySpecializations}" />
```
The actual datatbase binding is kindof complex as well. With multiple keys for each table in the hierarchy because each table can contain the same key that belongs to different parents... for example
taxonomy code : 207R00000X which breaks down to: 20 7R 00000 translates to: Allopathic,internal medicine,internal medicine
taxonomy code : 208M00000X which breaks down to: 20 8M 00000 translates to: allopathic, hospitalist, hospitalist
Each of those break downs is the keyfield in its own table.
Here is the design of my tables.
I am trying to have my lower control change each child as a new selection is made. I have that working. Now though when I select the top list, I want the bottom lists to reflect the Taxonomy of the selected item. I can get that done too by binding One-Way.
If I don't bind oneway I get this ErrorMessage:"The property 'TaxonomySpecializationID' is part of the object's key information and cannot be modified."
Ideally what I want to be able to do, is change the taxonomy of the selected DoctorTaxonomy using the listboxes. Maybe it just won't work...

I would like the algorithm to be generic such that I can pass in a 2D matrix with any dimensions. I am a C++ programmer by trade and am very tempted to write an old school loop to accomplish this, but I suspect there is a better way to do it in MATLAB.
I'd be rather want an algorithm that worked on an `NxN` matrix and go from there.

## The Challenge
The shortest code by character count that takes a single input integer `N` (N >= 3) and returns an array of indices that when iterated would traverse an `N`x`N` matrix according to the JPEG "zigzag" scan pattern. The following is an example traversal over an 8x8 matrix[src](http://en.wikipedia.org/wiki/Jpeg):
### Examples
(The middle matrix is not part of the input or output, just a representation of the NxN matrix the input represents.)
```
1 2 3
(Input) 3 --> 4 5 6 --> 1 2 4 7 5 3 6 8 9 (Output)
7 8 9
1 2 3 4
(Input) 4 --> 5 6 7 8 --> 1 2 5 9 6 3 4 7 10 13 14 11 8 12 15 16 (Output)
9 10 11 12
13 14 15 16
```
### Notes
- - [this question](https://stackoverflow.com/questions/3024939)
## Bonus
Extend your answer to take two inputs `N` and `M` (N, M >=3) and perform the same scan over an `N`x`M` matrix. (In this case `N` would be the number of columns and `M` the number of rows.)
### Bonus Examples

3,026,721 | 1 | null | null | 2 | 4,304 | I have set negative paddings on my custom seekbar so that the round thumb image can go outside the bar, but the thumb isn't rendered out there, is there anyway to force the thumb to be drawn outside those bounds?
Sorry guys, I'm new to Android development, and have been tasked with fixing an existing application. The problem is that we have a custom rounded looking track bar, which consists of two rounded 'end cap' images and a 1 px background that is tiled to create the seekbar. As far as I can tell there was never one image that could be set as the background of a normal SeekBar, which is why a custom one was created.
The thumb is a circle and needs to 'fit' into the end caps - the three pieces of the bar are in a relative layout. Right now I'm kind of unclear as to how the 1 px background png gets stretched as the seekbar bg, otherwise I would try to tack on the two endcaps onto that drawable some how ... ?
Please let me know if this was unclear and I'll try to post any followup info. Thanks in advance for any advice!!
Oh, I'm using Android 2.1 if that's relevant to anyone's interests :)
This is what it looks like when the thumb all the way over - outside of the seekbar. Ideally what I need is for the thumb to be shown as 'inside' the endcap image :-/

3,026,841 | 1 | null | null | 2 | 1,420 | I'm trying to do something which seems like it should be extremely simple and yet I can't see how. I have a very simple layout, a TextBox with an image next to it, similar to the way it might look adorned with an ErrorProvider in a WinForms application. The problem is, I want the image to be no higher than the TextBox it's next to. If I lay it out like this, say:
```
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBox Grid.Row="0" Grid.Column="0" MinWidth="100"/>
<Image Grid.Row="0" Grid.Column="1" Source="error.png" />
</Grid>
```
the row will size to the height of the image if the image is taller than the TextBox. This also happens if I use a DockPanel or StackPanel.
The naive solution would be to bind the `Height` to the `TextBox`'s `ActualHeight`. I'm sure this is wrong. But what's right?
Here's an example of what looks wrong to me: In both of these layouts (which are both horizontal `StackPanel`s), the `FontSize` is the only variable:
You can see that the first `TextBox` is constrained to the height of the icon, and as a result has an unnecessary bottom padding under the text. And the icon next to the second is out of scale to the `TextBox` it's next to.
As it happens, I found a completely different (and much better) way to approach the problem - originally I was scaling my layout by changing the `FontSize` on the `Window`, but using a `ScaleTransform` is a whole lot easier and seems to work perfectly. But even so, it still seems odd to me that it's so hard to do this.

anchor and dock properties don't work because they rely on parent container and here rectangles are on background image.

QUESTION:
I would like to do something like "relative-resize and position". Is that posible? So when I resize form, all the panels fits the rectangles on image.
This code works, only bad thing is when I am resizing main form, it "strugles". When I move mouse cursor while resizing it is not going smooth, it "strugles". And after half a second after i stop resizing panels are where they should be.
Image while resizing:
Image when I stop resizing, and after half a second after stop resizing:
Any suggestions about that or I should just leave it that way? There are lots of calculations here so that's why it struggles.

3,039,141 | 1 | 3,234,889 | null | 3 | 3,401 | I'm currently recoding a bar chart in my app to make use of the `Chart` class in the [WPF Toolkit](http://wpf.codeplex.com/). Using MVVM, I'm binding the `ItemsSource` of a `ColumnSeries` in my chart to a property on my viewmodel. Here's the relevant XAML:
```
<charting:Chart>
<charting:ColumnSeries ItemsSource="{Binding ScoreDistribution.ClassScores}"
IndependentValuePath="ClassName" DependentValuePath="Score"/>
</charting:Chart>
```
And the property on the viewmodel:
```
// NB: viewmodel derived from Josh Smith's BindableObject
public class ExamResultsViewModel : BindableObject
{
// ...
private ScoreDistributionByClass _scoreDistribution;
public ScoreDistributionByClass ScoreDistribution
{
get
{
return _scoreDistribution;
}
set
{
if (_scoreDistribution == value)
{
return;
}
_scoreDistribution = value;
RaisePropertyChanged(() => ScoreDistribution);
}
}
```
However, when I update the `ScoreDistribution` property (by setting it to a new `ScoreDistribution` object), the chart gets an series (based on the new ScoreDistribution) as well as keeping the original series (based on the previous ScoreDistribution).
To illustrate this, here are a couple of screenshots showing the chart before an update (with a single data point in `ScoreDistribution.ClassScores`) and after it (now with 3 data points in `ScoreDistribution.ClassScores`):
Now, I realise there are other ways I could be doing this (e.g. changing the contents of the original `ScoreDistribution` object rather than replacing it entirely), but I don't understand why it's going wrong in its current form. Can anyone help?

3,040,841 | 1 | 3,044,772 | null | 9 | 494 | I'd like to know if it ever makes sense to provide some functionality in a piece of software that is only available to the user through a context (right click) menu. It seems that in most software I've worked with the right click menu is always used as a quick way to get to features that are otherwise available from other buttons or menus.
Below is a screen shot of the UI I'm developing. The tree view on the right shows the user's library of catalogs. Users can create new catalogs, or add and remove existing catalogs to and from their library. Catalogs in their library can then be opened or closed, or set to read-only.
The screen shot shows the context menu I've created for the browser. Some commands can be executed independently from any specific catalog (New, Add). Yet the other commands must be applied to a specifically selected catalog (Close, Open, Remove, ReadOnly, Refresh, Clean UP, Rename).
Currently the "Catalog" menu at the top of the window looks identical to this context menu. Yet I think this may be confusing to the users as the tree view which shows the currently selected catalog may not always be visible. The user may have switched to the Search or Filters tab, or the left pane may be hidden entirely.
However, I'm hesitant to change the UI so that the commands that depends on a specifically selected catalog are only available through the context menu.

This is only leaking if I add it to the cell's contentView. If I just create it and let it be, the Leak instrument doesn't report any problem.
Also, if it helps, this is the history Leaks is displaying for this memory location. It looks like it at some point gets an additional retain message? This is not being done in my code.

3,045,258 | 1 | 3,045,933 | null | 0 | 3,536 | I have a ItemsControl in a ScrollViewer, and when the items exceed the width of the ScrollViewer they are put into a ContextMenu and shown as a DropDown instead. My problem is that when the Context Menu is first loaded, it saves the saves the size of the Menu and does not redraw when more commands get added/removed.
For example, a panel has 3 commands. 1 is visible and 2 are in the Menu. Viewing the menu shows the 2 commands and draws the control, but then if you resize the panel so 2 are visible and only 1 command is in the menu, it doesn't redraw the menu to eliminate that second menu item. Or even worse, if you shrink the panel so that no commands are shown and all 3 are in the Menu, it will only show the top 2.
Here's my code:
```

ContextMenuOpening="DropDownMenu_ContextMenuOpening">
<Button.ContextMenu>
<ContextMenu ItemsSource="{Binding Path=MenuCommands}" Placement="Bottom">

<ContextMenu.ItemTemplate>

<TextBlock Text="{Binding Path=DisplayName}" />

if (cMenu != null)

in the web only got references about DFS, A* or dijkstra, but i think they doesn't work in this case.

3,069,245 | 1 | null | null | 3 | 4,032 | The following problem is in 2D, so some simplifications can be made when suggesting answers.
I need to create closed areas (defined either by line segments or just set of points - convex polygon) from a set of points/line segments.
Basically I used Voronoi to generate "roads". Then I changed some of the data. Now I need a way to loop through that data (which is still line segments but doesn't comply with Voronoi anymore) and generate "neigbourhoods" that are bordered with the "roads".
I looked at some graph diagrams and shortest path theories, but I could not figure it out.
Logically it could be done by starting at left edge from one point, finding the way back to that point using the shortest path with available lines (using only clockwise directions). Then mark this line set down and remove from the data. Then you can repeat the same process and get all the areas like that.
I tried to implement that but it did not get me anywhere as I could not figure out a way to write a C++ code that could do that. Problem was with choosing the most counterclockwise line from available lines from a specific point. All angle based math I did gave wrong answers because the way sin/cos are implemented in c++.
So to summarize - if you can help me with a totally new approach to the problem its good, if not could you help me find a way to write the part of the code that finds the shortest clockwise path back to the beginning point using the line segment set as paths back.
EDIT: Added a picture to illustrate what I want to do.
Check the image here - (need 10 reputations before I can post it here :P)
I have a set of points (purple small dots). Another array defines what points make up a line (road). I want a way to define the area that is surrounded by roads so I can put buildings or smaller roads inside that and test against the edges so every region is separated. Hope this gives you more info on how to solve this problem.

A PostgreSQL database uses PL/R to call R functions. An R call to calculate Spearman's correlation looks as follows:
```
cor( rank(x), rank(y) )
```
Also in R, a naïve calculation of a fitted generalized additive model (GAM):
```
data.frame( x, fitted( gam( y ~ s(x) ) ) )
```
Here `x` represents the years from 1900 to 2009 and `y` is the average measurement (e.g., minimum temperature) for that year.
The fitted trend line (using GAM) is reasonably accurate, as you can see in the following picture:
The problem is that the correlations (shown in the bottom left) do not accurately reflect how closely the model fits the data.
One way to improve the accuracy of the correlation is to use a root mean square error (RMSE) calculation on binned data.
How would you implement the RMSE calculation on the binned data to get a correlation (between 0 and 1) of GAM's fit to the measurements, in the R language?
Is there a better way to find the accuracy of GAM's fit to the data, and if so, what is it (e.g., root mean square deviation)?
1. Call the PL/R function using the observed amounts and the model (GAM) amounts: correlation_rmse := climate.plr_corr_rmse( v_amount, v_model );
2. Define plr_corr_rmse as follows (where o and m represent the observed and modelled data): CREATE OR REPLACE FUNCTION climate.plr_corr_rmse(
o double precision[], m double precision[])
RETURNS double precision AS
$BODY$
sqrt( mean( o - m ) ^ 2 )
$BODY$
LANGUAGE 'plr' VOLATILE STRICT
COST 100;
The `o - m` is wrong. I'd like to bin both data sets by calculating the `mean` of every 5 data points (there will be at most 110 data points). For example:
```
omean <- c( mean(o[1:5]), mean(o[6:10]), ... )
mmean <- c( mean(m[1:5]), mean(m[6:10]), ... )
```
Then correct the RMSE calculation as:
```
sqrt( mean( omean - mmean ) ^ 2 )
```
How do you calculate `c( mean(o[1:5]), mean(o[6:10]), ... )` for an arbitrary length vector in an appropriate number of bins (5, for example, might not be ideal for only 67 measurements)?
I don't think `hist` is suitable here, is it?
The following code will solve the problem, however it drops data points from the end of the list (to make the list divisible by 5). The solution isn't ideal as the number "5" is rather magical.
```
while( length(o) %% 5 != 0 ) {
o <- o[-length(o)]
}
omean <- apply( matrix(o, 5), 2, mean )
```
What other options are available?
Thanks in advance.

3,073,615 | 1 | 6,006,006 | null | 3 | 5,344 | I've run into the issue of using a `UIBarButtonItem` with a custom color. Everything out on the 'net seems to indicate that the only way around this lack of official API support revolves around the use of images. This is all fine and dandy when developing for pre-iOS 4 devices, except when using the new iPhone 4. Creating an image for iPad and pre-iOS 4 devices is straightforward enough, but the images developed for those devices look absolutely horrid on iPhone 4. I suspect that this problem will be exacerbated further with the introduction of next generation devices.
Consider the example below. Notice how the default colored button is nice and smooth, but the iPhone 3GS image looks terrible. It does not seem very scalable (pun intended) to have to include multiple images for different resolution devices.
In the absence of an official API for changing the color of a `UIBarButtonItem`, what strategies are out there for creating images that scale well against differing resolution devices? This problem is hardly unique to UIBarButtonItems, how is the community adapting to other UI elements that are bitmapped? Is there a better solution for this particular case than using an image (such as using Quartz to draw it)?
If at all possible, please offer concrete code examples.

I've seen and done what was [mentioned before](https://stackoverflow.com/questions/127704/algorithm-to-return-all-combinations-of-k-elements-from-n/127898#127898), but that requires knowing the number of groups to begin with.

So it would generate products like:
UV Coating, Qty 500, Color 4:0
UV Coating, Qty 500, Color 4:1
etc...
Each of these Groups has an ID, and each item has a Group_Item_ID. So I can put them in an array such as:
```
$selections[1][...] // 1 = Coating
$selections[2][...] // 2 = Quantity
// ... = all selected Items in group

Here's an example array for the groups and their items:
```

The problem is that Chrome wants to be super helpful and validate these elements for me, except that it sucks at it. If it fails the built-in validation, there's no message or indication other than the element getting focus. I prefill URL elements with `"http://"`, and so my own custom validation just treats those values as empty strings, however Chrome rejects that. If I could change its validation rules, that would work too.
I know I could just revert back to using `type="text"` but I want the nice enhancements using these new types offers (eg: it automatically switches to a custom keyboard layout on mobile devices):
Is there a way to switch off or customise the automatic validation?

3,092,694 | 1 | 3,134,599 | null | 7 | 3,998 | I am trying to build a mathematical model of the availability of a file in a distributed file-system. I posted this question at MathOverflow but this might as well be classified as a CS-question so I give it a shot here as well.
The system works like this: a node stores a file (encoed using erasure codes) at r*b remotes nodes, where r is the replication-factor and b is an integer constant. Erasure-coded files have the property that the file can be restored iff at least b of the remote nodes are available and return its part of the file.
The simplest approach to this is to assume that all remote nodes are independent of each other and have the same availability p. With these assumptions the availability of a file follows the Binomial distribution, i.e. 
Unfortunately these two assumptions can introduce a non-neligible error, as shown by this paper: [http://deim.urv.cat/~lluis.pamies/uploads/Main/icpp09-paper.pdf](http://deim.urv.cat/%7Elluis.pamies/uploads/Main/icpp09-paper.pdf).
One way to overcome the assumption that all nodes have the same availability is to calculate the probability of each possible combination of availaible/non-available node and take the sum of all these outcomes (which is sort of what they suggest in the paper above, just more formally than what I just described). You can see this approach as a binary tree with depth r*b and each leave is one possible combination of available/not-available nodes. The file's availability is the same thing as the probablity that you arrive at a leave with >=b available nodes. This approach is more correct but has a computational cost of [](https://i.stack.imgur.com/LlZyG.png). Also, it doesn't deal with the assumption of node independence.
Do you guys have any ideas of a good approximation which introduces less error than the binomial distribution-aproximation but with better computational cost than [](https://i.stack.imgur.com/LlZyG.png)?
You can assume that the availability-data of each node is a set of tuples consisting of `(measurement-date, node measuring, node being measured, succes/failure-bit)`. With this data you could for example calculate the correlation of the availability between the nodes and the availability variance.

And no, specifying `height` in pixels doesn't achieve consistency either.
Is there any way to achieve text input height consistency across Gecko- and WebKit-based browsers (let alone IE and Opera) without resorting to JavaScript? And if I must use JavaScript, has someone already devised a jQuery plugin or something to easily do this?
Here's what not to do. The [jqTransform](http://www.dfc-e.com/metiers/multimedia/opensource/jqtransform/) plugin lets you skin form elements and promises that they'll look the same across browsers. Here's how the demo input looks in Chrome 5 on my Mac:
and here's how the same input looks in Firefox 3.6.4:
I haven't altered these screenshots in any way, just cropped them. Now, my first reaction is, "Ugh, I don't want to support Firefox." But there are currently more Firefox users than Safari and Chrome users combined, so that's not an option.
Someone, please help! I just want my forms to look the same across browsers! And by "look the same," I'm not talking about the `outline` on selection or anything like that; I'm just talking about having the same width, height, and text placement!

3,095,986 | 1 | 3,096,024 | null | 84 | 69,090 | I'm creating a little Java application which should have a progress indicator with percentages. In every loop it uses backspace `\b` to remove the displayed progress before displaying the next percentage.
Here's a simplified example:
```
public static void main(String[] args) throws Exception {
System.out.print("Progress: ");
for (int percentage = 0; percentage < 100; percentage++) {
System.out.print(percentage + "%");
Thread.sleep(10); // Stub for "long running task".
int length = String.valueOf(percentage).length() + 1;
while (length-- > 0) {
System.out.print('\b');
}
}
System.out.println("finished!");
}
```
This works perfectly in command prompt, but the backspace character isn't recognized in Eclipse's console (Galileo build 20090920-1017). It instead displays an empty square denoting an unknown character. See screenshot:
How do I get Eclipse to "display" the backspace properly? I.e. let it remove the previous character.
This is actually no showstopper since it will just be run in command console, but it would be just nice to get it to work in Eclipse as well :)

3,096,600 | 1 | 3,096,621 | null | 118 | 130,769 | Yesterday I found myself needing to zoom my Visual Studio text editor and was without a mouse (don't ask). Typically I do this by holding down and scrolling the mouse wheel. I also couldn't figure out how to tab into the area where you can specify your zoom level in the lower left hand corner of the text editor window.
So I guess I have two questions:
1. Is there a menu setting somewhere that I could have navigated to via the keyboard to set my zoom level?
2. Even better is there a similar keyboard command to holding CTRL and scrolling the mouse wheel?

3,097,193 | 1 | 3,244,819 | null | 0 | 222 | I have the following 2 consequative, unaltered frames from a video:
For some reason the camera made the 2nd much 'washed out' than the first. I want to make the 2nd look more like the 1st.
In the video I'm trying to process, there are lots of cases like this, where the 'exposure' changes suddenly from one frame to the next. I am able to find this parts of the video by looking at the image histogram for each frame, and when 2 adjacent frames have histograms that are too far apart, it's where this has happened. I can find this sections of different exposure, but I'm stumped with how to fix it.
As a programmer I'm familar with ImageMagick and that's about it. Since I have lots of frames, some automated hand off approach to fix this is by far the best solution. I am also totally unskilled with graphics editing programmes.
I've tried changing the exposure in imagemagick (with `-level 0,50%` etc.), but that doesn't help.
What ImageMagick commands (or other FLOSS image editing tools) will make the 2nd image look more like the 1st?

3,097,753 | 1 | 3,122,078 | null | 3 | 885 | I'm trying emulate the [Tint Effect](http://msdn.microsoft.com/en-us/library/documentformat.openxml.drawing.tinteffect.aspx) of Open XML. What it does is change the hue of pixels in an image by shifting the hue. It takes 2 parameters: 1) the `hue` (in degrees) and 2) the `amt` (the amount, a percentage). It is #2 that I'm having issues with. The spec states:
> : Shifts effect color values either towards or away from hue by the
specified amount.- -
Never minding the XML construction, I can emulate values that have an `amt` of 100%. So for example, if I want Blue (hue: 240°), I can create this (the one). Here's an example:
and (hue = 240, Amount = 100%).
 
This is achieved simply by setting the hue to 240, keeping saturation and luminance the same and converting to RGB and writing each pixel.
Here's what I can't achieve though:
Hue= (), Amount = , and , respectively
  
Again, the spec for `Amount` says . I've tried all sorts of ways here to get this to work, but can't seem to (`hue=hue*amount`, `originalhue * amount + hue`, etc.)
More examples: Hue= (), Amount = , , and , respectively. The one I can get.

3,099,677 | 1 | null | null | 1 | 701 | I'm running into a little problem with my infowindows: when a marker
is close enough to the edge of the map that the map needs to pan to
display the full infowindow, it does so but not enough to allow for a
few pixels of space between the infowindow and the border of the map.
Technically this works because content is made visible but it looks
awful.
Any ideas on how to make the infowindow have a margin?
```
marker = new GMarker(new GLatLng(this.latitude,this.longitude));
map.addOverlay(marker);
marker.openInfoWindow(this.infoWindow());
```
But this shows correctly if I use
```
map.openInfoWindow(marker.getLatLng(),this.infoWindow());

3,100,807 | 1 | 3,100,957 | null | 5 | 3,361 | I have recently started using doc-view in Emacs, but I am having quite a few problems with it. The main one is that I can't scroll down on pages. I can see the next or previous page using "n" or "p", but the commands to scroll up and down a page, which are supposedly SPACE and DEL, do not work. Well, to be fair, DEL works, but it goes to the previous page rather than scroll up to the bottom of the previous page. The result is that I can only see the top of the pdf pages, but not the bottom parts.
I tried changing the view to continuous, but that doesn't work either. This is what I tried changing:
I did check the customisations for doc-view, but the variables (or options, or whatever they are called) did not appear to me to be the ones which would solve my problem.
More information: I did manage to make SPACE and DEL work at some point, but I don't remember what I did, and I can't get it to work again. I am using Aquamacs.
Any ideas?
By the way, another problem I have is that doc-view causes Aquamacs to sort of crash, meaning it freezes everything, keeps "thinking", and I have to force quit Aquamacs to get it to work again. While this is not my main question, if anyone can tell me anything about this I would also appreciate.
Thanks!
: I tried what the answer below suggested, it didn't work, kept trying other things/commands, and then C-n and SPACE started working! I quit Aquamacs, started it again, opened a pdf document, and it is back to not working. Can someone please explain what is happening? How can I make this reliable?

3,102,619 | 1 | null | null | 0 | 215 | Alright, so here's the problem I'm having (it's a weird one.)
I added a new UIViewController for the app I'm building. The first view controller works perfectly, orients correctly, etc. The second one orients horribly.
This is how it looks if you start in landscape and then change orientation to portrait:
And then, if you start in portrait and switch to landscape:
It's worth noting that the button isn't a problem, it's there as a trigger for some code and doesn't need to stay correctly placed. Also, switching tabs makes the orientation display correctly, but it breaks as soon as you switch again.
I have absolutely no idea why this is happening. The only code I've added to this view controller is an IBAction that doesn't have any bearing (I commented it out to be sure.) Any ideas?

What I want to do is only show the cells that have value in it. In my case, I'm always going to have all the rows and 2 columns full. The 2 columns are 'day' and '19:00', however in the future I might add values for '18:00' etc.
So, how can I only SELECT the columns and rows which have data in them? Some type of 'WHERE: there is data'?
