"<Book:twRxQxBihF> {\n bookAuthor = Testing;\n bookTitle = \"IOS Development\";\n}",
"<Book:kxUTu3rcX5> {\n bookAuthor = Testing;\n bookTitle = \"Android Development\";\n}", .....
My project is about the mobile library and I want to filter the book by Author or Title
As of now I have the NSArray called parseResults to store the data that I parsed and another NSArray filteredResults to store the final result. I'm pretty new to IOS development and I'm pretty confused with the searching with the scope.
Sorry for my bad english.

Auto updating maps with current location also changes the zoom level.

$('#txt_dist').text(response.routes[0].legs[0].distance.text);

position.coords.longitude);
start = newPoint.toString();

I will prefer standard google map events
like zoom_changed instead of creating custom events for user zoom.
Any directions on this subject?

I have a swf loaded that uses Stage3D, displaying 3D content. When I overlay a video player, on full screen size, it will cause massive lag/jitter in the video content. The video content is loaded locally so there is no streaming to take into account. This only happens on some machines but considering the project this cannot be neglected.
I have since recoded my project to remove any form of loading i was doing with a Loader and just directly put the file path into the netstream and have then attached the netstream to StageVideo. But the problem still persists and I am at my wits end. I even set Stage3D to invisible during video playback.
It's a complete horror to debug because it's simply not a problem on my machine, but out of 10 people 4 of them have reported this problem and we can't release our product like this.
Any help to resolve this would be greatly valued and appreciated.

In the hclust? it says :
In hierarchical cluster displays, a decision is needed at each merge to specify which subtree should go on the left and which on the right....The algorithm used in hclust is to order the subtree so that the tighter cluster is on the left (the last, i.e., most recent, merge of the left subtree is at a lower value than the last merge of the right subtree).
I would like to get a different decision algorithm, in which the decision preserves similarity between a subtree and its 'uncle' subtree - In the sense that If I merged two trees that are 'red' and 'blue', and then did another merge between 'red+blue' to 'blue', then the blue will be next to the blue. This will result in a more pleasing to the eye figure, and also will more clearly show properties of the clustering.
(I know that one would hope that 'blue' would go with 'blue' to begin with, but with high-dimensional data, things are not so simple).

Can a flash application to access a REST service be built (by some customer of my RESTful service), so that
1. at least GET, POST, PUT, DELETE requests can be issued
1. Basic authentication is possible
1. HTTPS works
1. the vast majority of currently installed flash versions will work
?
In terms of 1. I read that all requests are converted to POST, but converted back to GET if there's an empty HTTP body.
Regarding 2. I read that it only works for POST requests, although http://helpx.adobe.com/flash-player/kb/authorization-header-request-flash-player.html does not give that impression, at least it's quiet about that point.
If 1. and/or 2. do not work, it would mean a lot of workarounds on the server side. Which has been hinted at by some of the posters on these issues, although some or all of the limitations apply only to `URLLoader`, and not to `Socket`, according to others. If that is the case, and Socket can be used by the majority of installed flash plugins out there, it seems by now there would be some library around that wraps away all the limitations and offers some `URLLoaderUnlimited` class or so. | flash | rest | basic-authentication | null | null | null | open | Accessing a RESTful service with Flash

1. When a thread is in the synchronized block of the remove method, I assume it will acquire a lock on the map object. Does that mean other threads trying to access the map via the getValue method will be blocked? (I'd like them to.)
2. When no thread is in the synchronized block of remove method, will threads accessing the getValue method function as usual i.e. not block each other? (I'd like that too).

I have a video stream that I want to display as simply as possible (no audio, just a sequence of frames with an unknown and variable framerate). This example (http://qt.gitorious.org/pyside/pysid...movie/movie.py) seems perfect except that my video is coming from an unconventional source. It's not a file but a network stream in a format that is not standardized. I can easily write code that receives each frame and my idea is to create a "QMovie provider" so that I can just display this stream on a label like in the example above.
My first thought was to just subclass QMovie and overwrite a few functions there but I started having second thoughts about that when reading the documentation (http://www.pyside.org/docs/pyside/Py...e.QtGui.QMovie) since I don't know what I should do about the "device" my instance would be reading from.
I noticed in the aforementioned documentation that QMovie uses QImageReader so my next thought was to extend that class and have it read frames from my stream. That poses similar questions however, for example, what should I do with the "supportedImageFormats()" function?
I've been experimenting with just directly updating the image on my QLabel every time I receive a new frame but then I've been getting the error "QPixmap: It is not safe to use pixmaps outside the GUI thread".
So basically I'm a little stumped and would really appreciate any pointers or tutorials on how to get a QLabel to display my video stream in a PySide application.
Kind regards,

I have been changing the column class in following way previously:
set.seed(1)

y = rep(1:2, 5),
k = rnorm(10, 5,2),
z = rep(c(2010, 2012, 2011, 2010, 1999), 2),

And back to numeric:
x <- 1:5
for(i in 1:length(x)){
df[,x[i]] <- as.numeric(as.character(df[,x[i]]))} # Character cannot become numeric
It occurred to me that maybe there is a better way doing this. I found [this question][1], which is almost exactly what I need:
convert.magic <- function(obj,types){
out <- lapply(1:length(obj),FUN = function(i){FUN1 <-
switch(types[i],
character = as.character,
numeric = as.numeric,
factor = as.factor); FUN1(obj[,i])})
names(out) <- colnames(obj)
as.data.frame(out)
}
However, for this function vector type has to be specified for each column:
convert.magic(df, rep("factor",5))
x <- c("y", "z")
convert.magic(df, x)
# Error in FUN(1:5[[1L]], ...) : could not find function "FUN1"
Could somebody help me and rebuild this function so that it works with column names and numbers, please? I am afraid that this would be too advanced for me...

I am using multiparting with initiate_multipart_upload() and upload_part() and so on.
It basically works.
BUT, for very large files (of, say, > 400MB) I cannot successfully upload all of the parts to S3. Basically, some of the parts are not OK.
So I would like to ask y'all the following questions:
[1] Will $s3->batch()->send() [after $s3->batch()->upload_part()] "do" retrying of failed parts? Or do I have to do it myself?
[2] If yes to [1], is the retrying using $s3->max_retries ?
[3] Will $s3->batch()->send() [after $s3->batch()->upload_part()] "do" paralleling of the parts. I mean, sending multiple parts at the same time? Or do I have to do it myself?
I've been looking at the API docs - and I've even been fishing around the source on GitHub - but I can't seem to find the answers to these questions.
Thanks a lot,
Daniel

I've designed a responsive site, with css media queries going all the way down to correctly display on 320 wide.
Want I want is the iPhone4 (640 x 960) when in landscape mode (640 wide) to adhere to media queries as if it's display-width = 320 pixels instead. Rationale: even though the iphone has more pixels, I do want to display a simplified layout to those user, similar to users of non high-density phones.
Any way to do this, by specifying some meta-tag for these high-pixel density phones for example?
Of course, I could define separate media-queries for iphone 4 and the like with `min-device-pixel-ratio: 2` but this leads to separate css media queries (one for low and one for high pixel density) which essentially have the same logic, which doesn't seem very DRY to me( http://en.wikipedia.org/wiki/Don%27t_repeat_yourself )
Strange thing is: the new Ipad 3 , with pixel density 2, DOES correctly render the way I want, i.e: it mimics (at least as css media queries are concerned) a device with half the resolution.

struct A {
A() {}
A(int) {}
};
struct B : A {
void init(int i);
};
void B::init(int i) {
A::A(i);
}
int main() {
B b;
b.init(2);
}
This compiled and ran using VC11 beta with no errors or warnings with /W4.
The apparent intent is for calling B::init to reinitialize the B's A base subobject. I believe it actually parses as a variable declaration for a new variable named `i` with type `A`. Compiling with clang produces diagnostics:
ConsoleApplication1.cpp:11:14: warning: declaration shadows a local variable
A::A(i);
^
ConsoleApplication1.cpp:10:22: note: previous declaration is here
void B::init(int i) {
^
ConsoleApplication1.cpp:11:14: error: redefinition of 'i' with a different type
A::A(i);
^
ConsoleApplication1.cpp:10:22: note: previous definition is here
void B::init(int i) {
^
It seems curious that the type can be referred to with the redundant class qualification.
Also, `A::A(i)` appears to be parsed differently by VS11 and clang/gcc. If I do `A::A(b)` clang and gcc create a variable `b` of type `A` using the default constructor. VS11 errors out on that saying `b` is an unknown identifier. VS11 appears to parse `A::A(i)` as the creation of a temporary `A` using the constructor `A::A(int)` with `i` as the parameter. When the redundant qualifier is eliminated VS parses the source as a variable declaration like clang and gcc do, and produces a similar error about shadowing the variable `i`.
This difference in parsing explains why VS11 will choke on more than a single extra qualifier; `A::A::A::A(i)`, and why, given that clang and gcc can accept one extra qualifier, any number more than one extra has the same result as one extra.
Here's another example with the redundant qualifiers in a different context. All compiler seem to parse this as a temporary construction:
class Foo {};
void bar(Foo const &) {}
int main() {
bar(Foo::Foo());
}
1. Why are redundant qualifiers allowed at all?
1. There are some contexts where constructors can be referred to, such as the syntax for inheriting constructors (`class D : B { using B::B; };`) but VS seems to be allowing it anywhere. Is VS wrong and are clang and gcc right in how redundant qualifiers are parsed?
1. I know VS is still a fair bit behind in terms of standards compliance, but I do find it a bit surprising that modern, actively developed compilers could be so divergent, in this case resolving a redundant qualifier as the name of a constructor (even though constructors don't have names) vs. resolving redundant qualifiers simply to the type, resulting in VS constructing a temporary where the others declare a variable. Are there still many differences this severe?
1. Clearly redundant qualifiers should be avoided in portable code. Is there a good way to prevent this construct from being used? | c++ | language-lawyer | null | null | null | null | open | Why are redudant class name qualifiers allowed?

My problem is that if I load this in google earth it draws two seperate lines on the earth. This is infact what I want to do. You can see two red lines on the picture below, two independant lines!
![enter image description here][1]
But when I process the linestring and then render the line from SQL Server geometry I get one line
So parsing this line of coordinates and putting into SQL Server gives me
![enter image description here][2]

The issue is the last 4 coordinates contains these values
-29.609000000000009 39.993, -29.613 40.033, -29.58 40.079, -29.588 40.106
Now Google Earth seems to know that the coordinates are different from each other and ***does not render a single line*** but splits it into two lines.
So my question is how do the same? Remember I have lots of these and I am wanting to put them on a Google Map as a custom layer - here is my issue - strange lines on my map.
![enter image description here][3]
Here is how google earth actually renders the full KML file.

My problem is that if I load this in google earth it draws two seperate lines on the earth. This is infact what I want to do. You can see two red lines on the picture below, two independant lines!
![enter image description here][1]
But when I process the linestring and then render the line from SQL Server geometry I get one line
So parsing this line of coordinates and putting into SQL Server gives me
![enter image description here][2]
LINESTRING (68.208 86.306, 70.926 86.203, 72.984 86.106, 75.029 85.989000000000019, 76.326 85.917, 78.403 85.768, 81.103 85.639, 83.143 85.556, 84.802 85.5, 86.802 85.418, 88.486 85.346, 89.98 85.296, 92.313 85.229, 94.155 85.155, 95.839 85.102, 97.27300000000001 85.028, 98.568 84.96, 99.444 84.911, 102.918 84.664, 103.943 84.578000000000017, 105.302 84.485, 106.759 84.369, 107.709 84.295, 108.939 84.194, 109.727 84.11, 110.959 83.965, 111.974 83.824, 112.843 83.674000000000021, 113.723 83.512, 114.558 83.321, 115.258 83.151, 115.793 83.014, 116.582 82.74, 117.171 82.539, 117.755 82.298, 119.1 82.087, 119.984 81.595, 121.004 81.115, 121.898 80.643, 122.639 80.206, 123.408 79.759, 125.188 78.99, 125.679 78.133, **-29.609000000000009 39.993, -29.613 40.033, -29.58 40.079, -29.588 40.106**)
The issue is the last 4 coordinates contains these values
-29.609000000000009 39.993, -29.613 40.033, -29.58 40.079, -29.588 40.106
Now Google Earth seems to know that the coordinates are different from each other and ***does not render a single line*** but splits it into two lines.
So my question is how do the same? Remember I have lots of these and I am wanting to put them on a Google Map as a custom layer - here is my issue - strange lines on my map.
![enter image description here][3]
Here is how google earth actually renders the full KML file.
![enter image description here][4]
If anyone is interested in seeing the original KML file then you can get it from here

This is for my Earthquake Site in New Zealand to show techtonic plates on a map.

The WPF application then needs to connect to a WCF service using these credentials, and stay connected to the service during its lifetime, because it receives callback notifications from the service via an ICallback interface.
This is the idea ([link to larger image](http://s14.postimage.org/r2gbc9uvz/SO_Question_2.png)):
***Questions:***
1. Should the credentials (username & password) information be fed through the Login ViewModel to a static service factory ?
2. Once the service client manages to connect to the WCF service - the Login window should close, and the MainWindow should be shown. How would the main window now know about the service client that the Login window has created ? how would the MainWindow be able to display notifications, once the arrive from the service ?
3. Should the login window pass the service client on to the MainWindow ? this seems like bad coding to me...
4. Say the WCF service goes down for some reason. I would like for the MainWindow to be able to show it (maybe using a red led image). How would the information about a disconnection be passed on from the service factory to the main window's view ? should the view hook to an event in the client ?
5. How would one go on to perform an 'auto-reconnect' to the WCF service in case it disconnects (maybe was taken down for maintenance) ?

I have multiple tables that are generated, most only have between 10 and 20 rows. Right now they are being automatically being split at the end of my page, but I would much rather have them stay together on the same page.
I have tried setting splitByRow to False upon Table instantiation, but that raises a "Not Implemented" error.
Also, I am not allowed make any changes to the reportLab python files, although I can see the code. Maybe I can subclass Table and disable split somehow?
What's the easiest way to disable flowable splitting?

The reason for these is the user can rename them on my webpage and store their own data to do with the uploaded PDF File. (They may have information like Customer Name, Publisher Name, Cost, ect)
I want to keep these values open to almost any data type..
The question I have, is what SQL datatype should I use? I dont mind having a Character Limit.. But I need to know the most efficient way to store it..

I call this function as I mentioned when the user authenticated with Facebook:

Any help is greatly appreciated and I know this problem may seem trivial but the image loader is very important as my initial graph calls do tend to take several seconds.

I've tried the plain *os.walk* & *stat*, suprocessing *du*, *find -type f -printf*.
###os.walk and du###
They both drill down to the bottom and stat every dirs, files. While this is required for the initial run, subsequent updates take hits from unnecessarily stat'ing unmodified directories and files. And I can't set the max-depth since I need to know what's changed in subdirs, if anything's been changed.
###find -type f###
This will look for files only. Not much of difference from above. At least this doesn't stat directories (directory info are gathered from residing files). No noticeable improvement in speed.
I had hoped to use directory's *modified time* to check whether something's been changed inside. If so, dive in, else skip. But *mtime* only updates for created, deleted, renamed items in the directory.
So is there no other way than this brute-forcing through all the dirs and files? | python | unix | diskspace | null | null | null | open | Fast way to get and update disk space usage?

I need to monitor the network disk space usage and generate report listing directories and their sizes per user.<br/>
There are directories containing over 1000 files with each one 20mb big.<br/>
Speed is the key as the report needs to be updated frequently.<br/>

What I'm trying to accomplish is the following:
Given the URL `dev-<sub>.example.com/resources/path/to/resource`, where `sub` varies, go to `/var/www/devEx_<sub>/override/resources/path/to/resource` if it yields a file or `/var/www/devEx_<sub>/main/resources/path/to/resource` otherwise (I can handle the 404s).
I can figure out a solution where I manually add each individual `sub` but I cannot figure out how to do it with a wildcard or backreference.
I've tried messing with `VirtualDocumentRoot` but I can never get the `devEx_<sub>` portion to show up in the `DOCUMENT_ROOT` for checking the resource.
I tried using a solution similar to this [ http://stackoverflow.com/questions/4069898/mod-rewrite-regex-too-many-redirects/4075369#4075369 ] but it always messes with the `REQUEST_URI`.
I've tried using something like this in the past:
RewriteCond $1 (^resources/.*)
RewriteCond %{DOCUMENT_ROOT}/override%{REQUEST_URI} -f
RewriteRule ^(.*)$ %{DOCUMENT_ROOT}/path1%{REQUEST_URI} [QSA,L]
RewriteCond $1 (^resources/.*)
RewriteRule ^(.*)$ %{DOCUMENT_ROOT}/main%{REQUEST_URI} [QSA,L]
Also, I would really love to understand using Apache / Mod_rewrite more so, if you have suggestions for a good technical guide or tutorial that would have helped me with this or some debugging techniques (since I have no idea how to debug these rewrite rules), I would greatly appreciate the knowledge so please share! | apache | mod-rewrite | null | null | null | null | open | Apache Mod_rewrite to change directories

The jQuery UI lib has a slider, but it seems that in order to get all the jQuery scripts and css loaded into the template, I have to switch to the HTML service instead of UI service for page generation.
At the moment I have my Gui builder form working ok, running something like this;
function doGet(e) {
var app = UiApp.createApplication();
app.add(app.loadComponent("DocEditorGui"));
return app;
}
and I have a jQuery slider in a html page that I can pull in like this;
function doGet(e) {
return HtmlService.createHtmlOutputFromFile('mySliderWidget');
}
However using an HTML file seems to be incompatible with the app.createHTML() HTML type widget, in that nothing is displayed if I pass the HTMLoutput contents. The HTML is definitely processed, as Logger.log shows the correct jQuery and html.
var t = HtmlService.createHtmlOutputFromFile('mySliderWidget');
var widgetHTML = container.createHTML(t.getContent());
widgetHTML.setStyleAttribute("background", "green");
Logger.log( t.getContent() );
vPanel.add(widgetHTML );
However presumably this is getting caught by caja also, because the effect appears to be stripping out all of the id tags for jQuery. The HTML is added, its all broken for jQuery.
Is there an example for this use-case, or am I way too early to be trying things like this?

The challenge is, when the type is `combobox`, then the `value` of the component is either `true` or `false` in String. And I have no privilege to modify the database attribute.
Then when I put a checkbox on the front end:
<field:checkbox field="enableEditing.setting" id="systemsetting_${formSettings.enableEditing.name}" z="user-managed"/>
I get the following exception:
Attribute 'value' is required when binding to non-boolean values
even I make a `value` attribute in the `checkbox.tagx`,
<field:checkbox field="enableEditing.setting" id="systemsetting_${formSettings.enableEditing.name}" value="${formSettings.enableEditing.setting}" z="user-managed"/>
I still have the same exception.
It seems like if the field is not a `boolean` type, then there is no way to make the checkbox work.
