Evaluate $ \lim_{x\rightarrow{\frac\pi2 }} (\sec(x) \tan(x))^{\cos(x)}$
without L'Hôpital's rule
I have tried changing limit to $\lim_{x\rightarrow0}$ and use some
trigonometry identity ($\sin^2(x)+\cos^2(x) = 1$ and $\sin (x+\pi/2) =
\cos(x)$) but doesn't work
I have no idea on how to do this now...

How to get started/pick/understand what web service tools to use
How to get started/pick/understand what web service tools to use
Ok, so this is an open-ended question. I would like to start with I am not
looking for an exact answer, as much as I am trying to find the correct
path to educating myself for what I need to do.
I am an iOS developer (5 years now) and I also know a decent amount about
HTML, CSS, and some PHP. I have dabbled in JavaScript and barely even
touched Ruby (On Rails), so it is fair to say that I am a novice web
developer. I can build great front ends but the backend and connecting it
are where I need help.
I am looking to build a product that has a few requirements. Here they are:
Scalable database to store ever increasing data over time. Users will be
continually adding new content that will need to be stored and also
indexed to be viewed later. This will include text, photos, and possibly
video clips (most likely not initially).
The ability to handle messaging. This is not a chat service, but rather
the ability to click on a user and say send message, and they will have a
dashboard section that will allow then to view and respond to those
messages. This will also be stored on the database. Nothing profound here,
standard implementation.
Easy access to maintain this data and content. I will need to be able to
quickly query the submitted content and grab all the data for users to
see.
Obviously the need to manage user accounts. Seems like a separate table or
DB for user accounts and linking them with content is needed. I feel like
this and number 3 are subsets of number 1 so I apologize if this is
redundant.
The bottom line is there are so many options, I have no idea what will or
will not work for my site. I barely know command line and terminal, I know
nothing about servers and Amazon Web Services seems like an amazing tool
but it is filled with tons of technical stuff I don't understand.
I am the type of person who will read books, watch videos, read tutorials
and constantly scan over Stack Overflow to learn new things, but in this
instance I am not sure what I should be learning.
Any idea's on what programming language I should be using? What web
service will fulfill my requirements? How will this all tie in to the HTML
side of things?
I am looking for some guidance on where to start, and ANY information will
be helpful. Links to articles to read, suggestions, personal experiences
are all welcome.
Thanks!

Drag and drop from outook to webapp
Drag and drop from outook to webapp
I'm coding a JSP with a drop zone where users can move any files (PDF,
.XDOC, .XLS, ....) for uploading and I want to make it works with email
too.
In my servlet, it seems to be OK if the dragged email is at first drop on
localdisk, then drop in the webpage. In that case i'm receiving some data.
Unfortunately, if it's directly drop from Outlook, nothinhg's happening...
Any suggestions to make it works ?

How can I find out the very first time linux machine start up?
How can I find out the very first time linux machine start up?
When we use uptime, it only shown us the up-time of ours machine since it
started from the last time it turning on/shutdown/reboot.
But, what if I want to get the time when our machine started from the very
first time when it installed?
Do Linux own this tools? Or any clues about how I can find out the answer
of it?

Removing and prepending in jQuery
Removing and prepending in jQuery
I am trying to achieve a simple unordered list, with the following
behaviour. When a list item is clicked, it needs to go on top of the list.
I managed to do it by assigning the element to a variable, removing "this"
(the clicked item) and prepending my element variable.
This seems to work. Only once.
I guess this is because the elements are removed from the DOM, and the new
ones are not "detected". WHat is the right way to do it?
Here's my simple code:
$('ul.selekta li').on('click', function() {
var element = $(this);
$(this).remove();
$('ul.selekta').prepend(element);
});
Any help is super appreciated!

Access a vector inside of a map that is inside another map
Access a vector inside of a map that is inside another map
I have a map called nfa (see below)
map<string, NFANode*> nfa;
nfa is filled with NFANode objects. (see below)
class NFANode {
public:
string label;
map<string,vector<NFANode*> >tr;
bool accepting;
bool starting;
NFANode(string s, bool a, bool x){
accepting = a;
label = s;
starting = x;
}
};
Inside each object there is another map call tr and inside of tr there is
a vector with information. I am trying to access the vector to print out
each element of the vector and cannot figure out how. I have been trying
to use an iterator with no luck.
map<string, NFANode*>::iterator nfaIt;
for (nfaIt = nfa.begin(); nfaIt != nfa.end(); ++nfaIt){
cout << "content of tr are: " << nfaIt->second->tr->second << endl;
}
Any help would be greatly appreciated.

When I refresh the page, it reloads the images which is something I don't
want
I am working on two WordPress blogs http://www.i-phony.com and
http://www.dz-ahbeb.com <<< Check them out
They have the same exact template. But the is a problem is only with the
first website. even though the settings are the same.
I tried disabling plugins and the problem was still there.
What do you suggest?
Thanks everyone

Setting a value that has parameters
Setting a value that has parameters
I'm looking for a way to set the value index.totalNumCitations to the
value I set in that while loop. I set the value to 1 initially so the for
loop would execute at least once. I tried obtaining the value before the
for loop and that also wasn't working. If someone could point me in the
right direction I would be very appreciative.
for (int i = 0; i < index.totalNumCitations; i++) {
while (inputInteger > 50 || inputInteger < 0) {
inputInteger = Integer.parseInt(sc.nextLine());
index.Index(inputInteger);
}
This is the method used in the while loop
public void Index(int totalNumCit) {
if (totalNumCit <= 50 && totalNumCit > 0) {
this.totalNumCitations = totalNumCit;
citationIndex = new Citation[totalNumCit];
} else {
System.out.println("Error: Please enter a number between 0 and 50.");
}
}

Microsoft JScript Runtime error on HttpGet
Microsoft JScript Runtime error on HttpGet
I have a JavaFX program that gets one page before the FX Gui loads, just
to verify that a user is logged on. Problem is that I get two consecutive
error windows telling me that "This property or method is not supported by
this object".
I have done some research but most of the stuff I found was about
JavaScript... Could it be that the HttpClient executes the JQuery on the
page?
Thanks in advance

How to initialize structure with compiler generated backing fields
How to initialize structure with compiler generated backing fields
Ultra simple question... How does one properly initialize private backing
fields on a structure? I get a compiler error:
Backing field for automatically implemented property 'Rectangle.Y' must be
fully assigned before control is returned to the caller. Consider calling
the default constructor from a constructor initializer.
Heres the source code.
public struct Rectangle
{
public Rectangle(int x, int y, int width, int height)
{
X = x;
Y = y;
Width = width;
Height = height;
}
public int Width { get; private set; }
public int Height { get; private set; }
public int X { get; private set; }
public int Y { get; private set; }
}

Do i have to create a certain nonclustered index every now and then?
Do i have to create a certain nonclustered index every now and then?
I have a database table that has more than 50 Million record and to
improve searching i had to create a non clustered indexes, and once i
create one it takes 5 ~ 10 minutes to be created so i guess in the
background it sorts the data according to the index.
So for example before adding index to my table searching was awful and
takes long time and when i added the non clustered index, searching was
fast.
But that was only when i had 50 million records.
The question is, what if i defined the index at the very beginning when
creating the table before adding any data to the table? Would it give the
same search performance i am getting right now? or do i have to delete and
recreate the index every now and then to sort the data regularly?
I am sorry if my question seemed stupid, i just started learning about
indexes and it is a confusing topic for me.

XPath search does not work
XPath search does not work
I try to access an xml file with dom4j. I also tried trough the dom of
org.w3c but this failed in the same way. I have a sample of the xml file
which I try to read below. I try to read the attribute xlink:href from the
element loc but for some reason this always fails. When I try the same
methods on an simple xml file I write myself, it does work. I've been
working on this for days now. Here is my method:
File file = new File("schemas/pfs-2013-04-01-presentation.xml");
SAXReader reader = new SAXReader();
Document document = reader.read(file);
XPath xpath = document.createXPath("//loc");
Map uris = new HashMap();
uris.put("", "http://www.xbrl.org/2003/linkbase");
uris.put("xbrli","http://www.xbrl.org/2003/instance");
uris.put("xlink","http://www.w3.org/1999/xlink");
uris.put("xsi","http://www.w3.org/2001/XMLSchema-instance");
xpath.setNamespaceURIs(uris);
List<Node> nodes = xpath.selectNodes(xpath);
From these 'nodes' I want to read the attributes later on. When I execute
this the List is empty however. This is something do not understand.
Can anyone help me with this please? thanks

I try to access an xml file with dom4j. I also tried trough the dom of
org.w3c but this failed in the same way. I have a sample of the xml file
which I try to read below. I try to read the attribute xlink:href from the
element loc but for some reason this always fails. When I try the same
methods on an simple xml file I write myself, it does work. I've been
working on this for days now. Here is my method:
File file = new File("schemas/pfs-2013-04-01-presentation.xml");
SAXReader reader = new SAXReader();
Document document = reader.read(file);
XPath xpath = document.createXPath("//loc");
Map uris = new HashMap();
uris.put("", "http://www.xbrl.org/2003/linkbase");
uris.put("xbrli","http://www.xbrl.org/2003/instance");
uris.put("xlink","http://www.w3.org/1999/xlink");
uris.put("xsi","http://www.w3.org/2001/XMLSchema-instance");
xpath.setNamespaceURIs(uris);
List<Node> nodes = xpath.selectNodes(xpath);
From these 'nodes' I want to read the attributes later on. When I execute
this the List is empty however. This is something do not understand.
Can anyone help me with this please? thanks

Map physical screen position to an array of GraphicsDevice with Swing
Map physical screen position to an array of GraphicsDevice with Swing
In Windows, each screen has an number or identity assigned I assume is
relative to how I physically connected my monitor cables. Key to my
question is that I can reconfigure these screens but they will keep their
identity.
Java's call to
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices() will
give me an array of GraphicsDevice.
How can I correlate the order of screens in the array with the Window
numbering? I'd be interested in a cross-platform solution.
For example, my Windows configuration looks like this
but the array returned looks like this
screens[0] = relates to screen 2
screens[1] = relates to screen 3
screens[2] = relates to screen 1
So the physical
NB the code I get I'd like to use is along the lines of this
frame.setLocation(
screens[i].getDefaultConfiguration().getBounds().x, frame.getY());
where i should be the physical number and not the position in the array
(or its mapping if you see what I mean).

Chrome performance: "legal" property names vs
Chrome performance: "legal" property names vs
So this is an interesting one... While I was testing the performance of
setAttribute vs. normal property set on an element, I found an odd
behavior, which I then tested on regular objects and... It's still odd!
So if you have an object A = {}, and you set its property like
A['abc_def'] = 1, or A.abc_def = 1, they are basically the same. But then
if you do A['abc-def'] = 1 or A['123-def'] = 1 then you are in trouble. It
goes wayyy slower. I set up a test here: http://jsfiddle.net/naPYL/1/.
They all work the same on all browsers except chrome. The funny thing is
that for "abc_def" property, chrome is actually much faster than Firefox
and IE, as I expected. But for "abc-def" it's at least twice as slow.
So what happens here basically (at least from my tests) is that when using
"correct" syntax for properties (legal C syntax, which you can use with
dot properties) - It's fast, but when you use syntax that requires using
brackets (a[...]) then you're in trouble.
I tried to imagine what implementation detail would distinguish in such a
way between the two modes, and couldn't. Because as I think of it, if you
do support those non-standard names, you are probably translating all
names to the same mechanics, and the rest is just syntax which is compiled
into that mechanic. So . syntax and [] should be all the same after
compilation. But obviously something is going the other way around here...
Without looking at V8's source code, could anyone think of a really
satisfying answer? (Think of it as an exercise :-))

What Javascript library should I use for Calendaring that is *NOT* integrated with the phone?
What Javascript library should I use for Calendaring that is *NOT*
integrated with the phone?
I'm developing a Javascript application that needs its own calendar,
separate from the native Android/ iPhone calendar.
What Javascript library allows for me to manage a calendar separate from
the default "main" calendar on the phone?
My goal is to list appointments, and have a Day/Week/Month view, ideally
in a form that the user is already familiar with (Android/iOS)
integrated with the phone?

Why GLSL "optimizing" this shader?

model's coordinates

but for some reason glGetUniformLocation for mdlRotMatrix and
mdlScaleMatrix returns -1. I can see values 4-6 for other uniforms. Why it
happens? I checked names and copy-pasted several times, made error in code
to check and got compilation error (shader works with exact file), so
names and shader are intact.

Return NULL from XML EXPLICIT subquery where no rows exist
Return NULL from XML EXPLICIT subquery where no rows exist
This is probably simple to do, but I'm having a brain-fart on this one...
I'm using FOR XML EXPLICIT as part of a subquery so that I can explicitly
define the format of the returned XML. Therefore I'm using UNION ALL to
define that format.
This is working fine, but I need it to return NULL if there are no rows in
that sub-query... at the moment it is returning an empty root element:
<codes/>. That is because I need the first row for the definition.
Here is a sqlfiddlecom with everything below for you to look at.
This is a version of the TSQL as it currently is...
SELECT
P.[PROJECTID],
P.[PROJECTNAME],
( SELECT *
FROM (
SELECT
1 AS TAG,
NULL AS PARENT,
NULL AS 'codes!1',
NULL AS 'code!2!!element',
NULL AS 'code!2!split'
UNION ALL
SELECT
2 AS TAG,
1 AS PARENT,
NULL,
C.[CODE],
C.[SPLIT]
FROM [CODES] C
WHERE C.[PROJECTID] = P.[PROJECTID]
) AS [CODEXMLDATA]
FOR XML EXPLICIT
) AS [CODESXML]
FROM [PROJECTS] P
Example data would be along the lines of
PROJECTS table
PROJECTID PROJECTNAME
1 This
2 That
3 Other
CODES table
PROJECTID CODE SPLIT
1 ABC 45
1 BCD 65
2 CDE 100
The result is coming out as...
PROJECTID PROJECTNAME CODESXML
1 This <codes><code split="45">ABC</code><code
split="55">BCD</code></codes>
2 That <codes><code split="100">CDE</code></codes>
3 Other <codes/>
The result I need is (note the NULL on the 3rd line)...
PROJECTID PROJECTNAME CODESXML
1 This <codes><code split="45">ABC</code><code
split="55">BCD</code></codes>
2 That <codes><code split="100">CDE</code></codes>
3 Other NULL
Can anybody give me a hint how I can make it return NULL when there are no
CODES?

Is this an reasonable use case for storing JSON in MySQL?
Is this an reasonable use case for storing JSON in MySQL?
I understand that it is generally considered a "bad idea" to store JSON in
a MySQL column due to the fact that it becomes difficult to maintain and
is not easily searched, or otherwise queried. However, I feel that the
scenario I have encountered in my application is a reasonable use case for
storing JSON data in my MySQL table. I am indeed looking for an answer,
particularly one that may point out any difficulties which I may have
overlooked, or if there is any good reason to avoid what I have planned
and if so, an alternate approach.
The application at hand provides resource and inventory management, and
supports building Assemblies, which may contain an infinite number of sub
assemblies.
I have a table which holds all of the metadata for items, such as their
name, sku, retail price, dimensions, and most importantly to this
question: the item type. An item can either be a part or an assembly. For
items defined as assemblies, their contents are stored in another table,
item_assembly_contents whose structure is rather expected, using a
parent_id column to link the children to the parent. As you may expect, at
any time, a user may decide to add or remove an item from an assembly, or
otherwise modify the assembly contents or delete it entirely.
Here is a very simple example Assembly in JSON format, demonstrating a
single Sub Assembly structure.
{
"id":1,
"name":"Fruit Basket",
"type":"assembly",
"contents":[
{
"id":10,
"parent_id":1,
"name":"Apple",
"type":"part",
"quantity":1
},
{
"id":11,
"parent_id":1,
"name":"Orange",
"type":"part",
"quantity":1
},
{
"id":12,
"parent_id":1,
"name":"Bag-o-Grapes",
"type":"assembly",
"quantity":1,
"contents":[
{
"id":100,
"parent_id":12,
"name":"Green Grape",
"quanity":10,
"type":"part"
},
{
"id":101,
"parent_id":12,
"name":"Purple Grape",
"quanity":10,
"type":"part"
}
]
}
]
}
The Fruit Basket is an Assembly, which contains a Sub-Assembly named "Bag
o Fruits". This all works wonderfully, until orders and shipments come
into consideration.
Take for example, an outbound shipment containing an assembly. At any
time, the user must be able to see the contents of the assembly, as they
were defined at the time of shipment, which rules out simply retrieving
the data from the items and item_assembly_contents table, as these tables
may have been modified since the shipment was created. Therefore, assembly
contents must be explicitly saved with the shipment so that they may be
viewed at a later date, independent of the state or mere existence of the
assembly in the user's defined inventory (that being, the items table).
It is storing the assembly contents along side the shipment contents that
has me a bit confused, and where I believe storing the data in JSON is the
best solution. It is critical to understand the following points about
this data:
It will NOT be used for Searches
Any UPDATES will simply overwrite the contents of the row
It will MOST OFTEN be used to populate a Tree View on the Client, which
will accept the JSON as it exists in the table, without any need for
modification.
See this image for a (hopefully) more clear visualization of the data:
Questions
Is this a reasonable use case? Are my concerns meaningless?
Is there anything that I have looked over that may come back to bite me?
Can you provide an explanation why I should NOT proceed with my proposed
schema, and if so....
Can you provide an alternative approach?
As always, thank you so much for your time and please do not hesitate to
request clarification or additional information.

The Fruit Basket is an Assembly, which contains a Sub-Assembly named "Bag
o Fruits". This all works wonderfully, until orders and shipments come
into consideration.
Take for example, an outbound shipment containing an assembly. At any
time, the user must be able to see the contents of the assembly, as they
were defined at the time of shipment, which rules out simply retrieving
the data from the items and item_assembly_contents table, as these tables
may have been modified since the shipment was created. Therefore, assembly
contents must be explicitly saved with the shipment so that they may be
viewed at a later date, independent of the state or mere existence of the
assembly in the user's defined inventory (that being, the items table).
It is storing the assembly contents along side the shipment contents that
has me a bit confused, and where I believe storing the data in JSON is the
best solution. It is critical to understand the following points about
this data:
It will NOT be used for Searches
Any UPDATES will simply overwrite the contents of the row
It will MOST OFTEN be used to populate a Tree View on the Client, which
will accept the JSON as it exists in the table, without any need for
modification.
See this image for a (hopefully) more clear visualization of the data:
Questions
Is this a reasonable use case? Are my concerns meaningless?
Is there anything that I have looked over that may come back to bite me?
Can you provide an explanation why I should NOT proceed with my proposed
schema, and if so....
Can you provide an alternative approach?
As always, thank you so much for your time and please do not hesitate to
request clarification or additional information.
Why does Visual Studio (2008 and 2010) put three bytes at the beginning on newly created text and xml files?
Why does Visual Studio (2008 and 2010) put three bytes at the beginning on
newly created text and xml files?
When I create a new TEXT or XML file within Visual Studio (2010) three
bytes are set at the top of the file. They can't be seen unless you're
using a binary editor.
Why are they there and what do they do?
Is there a way to stop Visual Studio from putting them there?
As it stands I cannot use Visual Studio to XML files because these bytes
screw up the parser.

I have tried below code. But this is not working. This is just rotating
the image.
Matrix matrix = new Matrix();
matrix.postRotate(curValue);
//matrix.postScale(curValue, curValue);
Bitmap resizedBitmap = Bitmap.createBitmap(bitmaprotate, 0, 0, bmpWidth,

Is it possible to find all visited links in the browser?
Is it possible to find all visited links in the browser?
This is the snippet from this code:
<a href='www.apple.com'>apple</a>
<a href='www.google.com'>Google</a>
__
a{
display: block;
background-color: rgba(200,200,180,0.4);
margin-bottom: 18px;
line-height: 160%;
}
a:visited{
background-color: red;
}
It applies :visited css to second hyperlink and if I change first
hyperlink from www.apple.com to http://www.apple.com it applies :visited
css to that also (strange?).
Why I am doing this is because one of the QA person says that one of the
hyperlink in my page always shows as visited while he didn't visited the
link. Even if we reset safari it still shows as visited. Unless we restart
the mac it always says visited.
Is it possible to show him the list of hyperlinks he visited. ( It is not
in browser history as well )

How can I separate user inputted string and store it into an array
How can I separate user inputted string and store it into an array
I was wondering if you could help me and figure this out without using
something like strtok. This assignment is meant for me to build something
that will accept input and direct the user to the right area. I want to
get something like....
Help Copy
and it stores it as
array[1] = Help
array[2] = Copy.
I tried to do something like cin>>arr[1]; and cin>>arr[2] but at the same
time what if the user enters copy then I am not sure how to do it cause if
I put just one cin then what if the user puts help copy.
Basically I am not sure how to accept any size input and store anything
they put in as elements in an array.
I would try something like cin.get or getline but they don't seem to
really help me and my cin idea was not helpful at all.
This is what I have so far.
int main()
{
string user;
cout<<"Hello there, what is your desired username?"<<endl;
cin >> user;
system("cls");
cout<<"Hello, " << user << "! How are you doing?"<<endl<<endl;
cout<< user << ": ";
return 0;

How to disable audio output processing on an htc phone with Android
How to disable audio output processing on an htc phone with Android
I am trying to measure the audio path from speaker to microphone on two
different phones, an htc Wildfire S running Android 2.3.5, and an htc One
X running Android 4.0.3. Using Eclipse, I coded an app that has wave files
played back using an android.media.MediaPlayer. However, my recordings
show that something like an automatic gain control is applied to the
output, as loud files are attenuated, and the recordings feature almost
equal amplitudes, although the played back files vary widely in their
respective amplitudes.
How can I switch any processing of the audio data off prior to output? I
would like to obtain direct control over raw audio output.
Thanks in advance.

What is the point of Partial Views in Asp.net MVC
What is the point of Partial Views in Asp.net MVC
Ive noticed that there seems to be no real difference between a view and a
partial view. For instance, one can create a view but can render it as a
partial view by using
@Html.Partial("ViewName")
or by specifying that its action return it as
return PartialView();
Ive noticed that the opposite is also the case - ie, one can create a
partial view but if it is returned as a full view, it will be displayed
with the default layout for the views.
My question is this - When adding a new view in Visual Studio, one is
given the option of creating a view that is partial or not. Isn't this
redundant, since a view can be rendered as both a partial and a full view
anyway?

i am trying to open a default https://localhost page from my default xampp

CHROME
SSL connection error Unable to make a secure connection to the server.
This may be a problem with the server, or it may be requiring a client
authentication certificate that you don't have. Error 107

FIREROX
The connection was interrupted The connection to localhost was interrupted
while the page was loading. The site could be temporarily unavailable or
too busy. Try again in a few moments. If you are unable to load any pages,
check your computer's network connection. If your computer or network is
protected by a firewall or proxy, make sure that Firefox is permitted to
access the Web.
I have done all the settings for ssl, where as i dont think i need to do
any setting for it the version for xampp is 1.7 and the same version
installed on my home pc runs the default page https://localhost perfectly
without any custom settings , the thing that i cant help noticing is the

which replaces some part of the old line, to the same position the old
line was located in the file (meaning the same line number). The newline
tends to print out at the bottom of the file. How can I change that?

Compare two int lists
Compare two int lists
I have an object that looks like this:
public class TestObject {
private string name = string.Empty;
private List<int> ids;
public TestObject(List<int> ids, string name)
{
this.ids = ids;
this.name = name;
}
public string Name
{
get { return name; }
set { name = value; }
}
public List<int> Ids
{
get { return ids; }
set { ids = value; }
}
}
I get a list of of these objects that looks something like this:
List<TestObject> listTest = new List<TestObject>();
listTest.Add(new TestObject((new int[] { 0, 1, 5 }).ToList(), "Test1"));
listTest.Add(new TestObject((new int[] { 10, 35, 15 }).ToList(), "Test2"));
listTest.Add(new TestObject((new int[] { 55 }).ToList(), "Test3"));
listTest.Add(new TestObject((new int[] { 44 }).ToList(), "Test4"));
listTest.Add(new TestObject((new int[] { 7, 17 }).ToList(), "Test5"));
Then I have several lists of integers like so:
List<int> list1 = new List<int>();
list1.Add(0);
list1.Add(1);
list1.Add(5);
List<int> list2 = new List<int>();
list2.Add(4);
List<int> list3 = new List<int>();
list3.Add(7);
List<int> list4 = new List<int>();
list4.Add(55);
What I'd like to do is to be able to check these integers lists against
the TestObject list and extract TestObjects that are equal. In other
words, in this example list1 would find a hit in the object at position 0,
list4 would find a hit in position 2, there is no hit for list3 as there
is only a partial in position 4 and there is no hit for list2 as it does
not exist.
I thought first that it could be done with "Except." So, if there is
nothing between the listN and listTest at n position then that is a hit??
The thing is how to compare the listN to the list in the object at
position N in listTest??
I have an object that looks like this:
public class TestObject {
private string name = string.Empty;
private List<int> ids;
public TestObject(List<int> ids, string name)
{
this.ids = ids;
this.name = name;
}
public string Name
{
get { return name; }
set { name = value; }
}
public List<int> Ids
{
get { return ids; }
set { ids = value; }
}
}
I get a list of of these objects that looks something like this:
List<TestObject> listTest = new List<TestObject>();
listTest.Add(new TestObject((new int[] { 0, 1, 5 }).ToList(), "Test1"));
listTest.Add(new TestObject((new int[] { 10, 35, 15 }).ToList(), "Test2"));
listTest.Add(new TestObject((new int[] { 55 }).ToList(), "Test3"));
listTest.Add(new TestObject((new int[] { 44 }).ToList(), "Test4"));
listTest.Add(new TestObject((new int[] { 7, 17 }).ToList(), "Test5"));
Then I have several lists of integers like so:
List<int> list1 = new List<int>();
list1.Add(0);
list1.Add(1);
list1.Add(5);
List<int> list2 = new List<int>();
list2.Add(4);
List<int> list3 = new List<int>();
list3.Add(7);
List<int> list4 = new List<int>();
list4.Add(55);
What I'd like to do is to be able to check these integers lists against
the TestObject list and extract TestObjects that are equal. In other
words, in this example list1 would find a hit in the object at position 0,
list4 would find a hit in position 2, there is no hit for list3 as there
is only a partial in position 4 and there is no hit for list2 as it does
not exist.
I thought first that it could be done with "Except." So, if there is
nothing between the listN and listTest at n position then that is a hit??
The thing is how to compare the listN to the list in the object at
position N in listTest??
Reassigning a generic Java variable
Reassigning a generic Java variable
I'm slightly confused why the following does not compile:
public <E extends Object> E doSomething() {
return new Object();
}
I've researched the problem a little and found various fixes like casting
to an (E) or using Class Literals but I'm still unsure what is actually
wrong with the above.

jQuery video clicking image to action video play (with placeholder on YT player)
jQuery video clicking image to action video play (with placeholder on YT
player)
I'm trying to click a thumbnail image in one div to play an embedded
youtube video in another div (embedded as iframe) as a full size video.
I've gotten that far, but instead of the YT player showing when the page
loads i need a static image to replace it. I'm very new to jquery but have
created the code from a few other answers on here so am a bit stuck on how
to do the replacement image along with the rest of it. any help would be
amazing.
any chance of any of this working on image maps instead of divs?

Regex: remove double parenthesis but preserve singles
Regex: remove double parenthesis but preserve singles
I have a bunch of co-ordinate data coming back in the following format:
TYPE ((lat long, lat long), (lat long, lat long), (lat long))
I'm trying and failing at creating a regex that will remove anything
except digits, spaces, commas, hypens, and SINGLE parenthesis; I can't for
the life of me figure out how to remove double parenthesis but not single.
I don't need to replace the double parenthesis with singles, just remove
them.
What I've come up with so far is:
preg_replace('/[^0-9,.-\s\(\)/', '', $val);
But this removes ALL brackets, which is not what I want. I've been trying
with lookahead/lookbehind assertions but can't quite seem to get it
right...

Chrome hide element on scroll after orientationchange
Chrome hide element on scroll after orientationchange
I'm facing a problem I can't figure out how to solve. I'm almost sure this
is a Chrome bug since in other browsers it works like a charm but I want
to be sure. On my website, developed using a mobile first and responsive
design approach, I have a menu that uses the Left Nav Flyout pattern. On
Tablets and desktops, I show it full width.
When I load the website on my smartphone (specifically an Android device)
using Chrome in Portrait mode, once I rotate the device (passing in
Landscape mode) and start to scroll the page, as soon as I reach the menu
position, the latter magically disappears. What is really strange is that
if you try to click the space that now is completely white, you can see
that the links are actually there. I tried to use the inspector to find
the problem but didn't succeed.
So, wow can I solve the problem? Anyone else had this issue before? If you
know it's a bug, I'm glad to add a temporary workaround as well.

Twitter Bootstrap content in Google Chrome is expanded all the way
horizontally and not vertically
I have just finished my first responsive site with Twitter Bootstrap and
it uses scrollspy to scroll up and down through the five sections of the
site(Home,etc,etc,etc,etc). The site works just fine in Firefox and IE but
in Chrome and Safari the content of the lower sections is expanded
horizontally and not vertically like it does with Mozilla Firefox and IE.

Div appear after scroll past a div
Div appear after scroll past a div
I know there are a lot of tutorials to let a div appear after scroll down
a certain amount of pixels.
But what I want is to let a div appear when the user scrolls past another
div. And when they scroll back up it has to disappear again.
Why not after an amount of pixels? I want to use this for my menubar to
appear on the top of my page after the user scrolls past the banner image.
BUT when you scale down the browser (mobile, tablet, small screen...) the
banner image will scale down to! The image will not be the same height as
before. The menubar would appear to late or to earlier;) that's why I want
the menubar to appear after that image (div).
Hope you guys can help!

PHP - mysql_fetch_assoc() issue
PHP - mysql_fetch_assoc() issue
I'm new to PHP and I'm trying to learn how to display data I select from a
mysql database (phpmyadmin). My current php code consists of 2 files
connect.inc.php and connecting.php:
conncet.inc.php is the file used to establish connection with the database:
<?php
//Varialbles
//MYSQL details
$mysql_server='localhost';
$mysql_user='root';
$mysql_user_pass='12345678';
$mysql_db='test';
//Messages
$db_conn_error='Could not connect to database';
if(mysql_connect($mysql_server, $mysql_user, $mysql_user_pass)
and mysql_select_db($mysql_db)){
echo 'Connection is ok'.'<br>';
}
else
{
echo 'Connection is not ok';
}
?>
while the other file (connecting.php) should display any records in the
particular table called food :
<?php
require 'connect.inc.php';
$query = "SELECT 'food', 'calories' FROM food ORDER BY 'id'";
if ($query_run = mysql_query($query)){
while($query_row = mysql_fetch_assoc($query_run)){
$food = $query_row['food'];
$calories = $query_row['calories'];
echo $food . ' has '.$calories.' calories.<br>';
}
}
else
{

}
?>
Additional details:
server name : localhost
user : root
password : 12345678
database name : test
table name : food
field names : id, food, calories, healthy_unhealthy
Ths issue is that whenever i execute code in the file connecting.php i
always get the following:
Connection is ok
food has calories calories.
food has calories calories.
When it should say
Connection is ok
Pizza has 1000 calories
Salad has 200 calories
Help is highly appreciated :)
Thanks in advance,

xcode 5 GM is mercilessly hanging all the time
xcode 5 GM is mercilessly hanging all the time
I don't know what is going on, but I have downloaded xcode 5 gm and it is
worse than dp 6. It hangs when creating a brand new project. It hangs when
I rename a class, and when trying to set up a local git repository. It is
a blank project master/detail template.
Does anyone have any idea what to do? I have already deleted xcode 5 by
dragging the app to the trash.
Is there anything I can do about this? I assume that I will want to remove
all traces of xcode from my computer and retry again? I'm on the latest
mountain lion os.

Objectless A* Implementation
Objectless A* Implementation
My current pathfinder is a .NET 2.0 implementation of Eric Lippert's Path
Finding Using A* in C# 3.0 series. Eric's pathfinder is excellent (if you
haven't read his articles, do read them), but I wouldn't agree with the
assertion that in order to get a faster implementation of A* you'd have to
use C++.
Eric's algorithm creates an enormous amount of temporary objects each time
it is ran, even if the Node type is a struct; every piece of a Path is an
object, and a large percentage of insertions into his PriorityQueue class
results in a new Queue object.
In my application, I have to generate a large number of A* paths in
soft-realtime, but I'm allowed to give-up after the closed-list exceeds a
certain threshold. It should be possible for me to run A* without
allocating any new memory between calls. However, presently nothing is
reused, everything is reallocated again on the next call.
If I were coding an A* implementation in C++, one of my design goals would
be allowing the user to specify a starting capacity of the pathfinder and
reusing any memory allocated for the next time the pathfinder is ran
(whatever results the user wanted to keep, that user would be instructed
to make a copy). This is an extremely efficient approach, and I think it's
something C# can accomplish also.
This seems like it could be really tricky to write though, has it ever
been done before? Are there pitfalls that you'd think I'd run into with
trying to implement it?
The non-trivial problematic areas in Eric's algorithm are:
Path (an implementation of an immutable stack) - Forces the use of objects
(regardless of whether Node is a struct).
PriorityQueue - Most insertions will result in a new Queue object, and
when it doesn't, it could still result in the Queue doing an internal
resize.

How to detect outliers in an ArrayList
How to detect outliers in an ArrayList
I'm trying to think of some code that will allow me to search through my
ArrayList and detect any values outside the common range of "good values."
Example: 100 105 102 13 104 22 101
How would I be able to write the code to detect that (in this case) 13 and
22 don't fall within the "good values" of around 100?

heatmap in a single select or stored procedure
heatmap in a single select or stored procedure
I have a table of server requests - each with a timestamp. What I would
like to accomplish is that the result of my query (or preferably a stored
procedure) gives me, for a single day, a table with each hour of the day
across the top (from 0 to 23) and each minute of the hour down the side
(from 0 to 59). The intersecting data would display the count of requests
per minute, per hour.
What I have tried so far is group the minutes by hour of the day, and
manipulate that in excel to produce the 24x60 matrix using:
SELECT DatePart(HH,Timestamp) as [Hour]
, DatePart(MI,Timestamp) as [Minute]
, Count(*) as [Count]
FROM Requests
WHERE DatePart(Day,Timestamp) = 12
GROUP BY DatePart(HH,Timestamp),
DatePart(MI,Timestamp)
ORDER BY DatePart(HH,Timestamp)
, DatePart(MI,Timestamp)
Any help would be greatly appreciated, thanks in advance for your time :)
I have a table of server requests - each with a timestamp. What I would
like to accomplish is that the result of my query (or preferably a stored
procedure) gives me, for a single day, a table with each hour of the day
across the top (from 0 to 23) and each minute of the hour down the side
(from 0 to 59). The intersecting data would display the count of requests
per minute, per hour.

Button animations on one thread and working in another thread
Button animations on one thread and working in another thread
I think my problem is very basic but i am new to android so just need this
solution. I have 20 buttons and all of them are animating(translation and
scaling) on the screen. I want to create a new thread and do animations
there. Those buttons have images on them,code is working fine in UI thread
but sometimes i am getting ANR message and exception that application may
be doing too much work on its main thread. Please help Thank you

R read.table loops row column entries to next row

This is the first time I encountered this problem using read.table: For

entries into the next rows.
I have a .txt file with rows of variable and unequal length. For reference
this is the .txt file I am reading:
http://www.broadinstitute.org/gsea/msigdb/download_file.jsp?filePath=/resources/msigdb/4.0/c5.bp.v4.0.symbols.gmt

For instance, column entries for row 6 gets looped to fill row 7 and row
8. I seem to only this problem for row entries with very large number of
columns. This occurs for other .txt files as well but it breaks at
different column numbers. I inspected all the row entries at where the
break happens and there are no unusual characters in the entries (they are
all standard upper case gene symbols).
I have tried both read.table and read.delim with the same result. If I
convert the .txt file to .csv first and use the same code, I do not have
this problem (see below for the equivalent output). But I don't want to
convert each file first .csv and really I just want to understand what is
going on.
Correct output if I convert to .csv file:
MSigDB.collection = read.table(fileName, header = FALSE, fill = TRUE,
as.is = TRUE, sep = ",")

How to use jquery custom validation plug-in for mvc
How to use jquery custom validation plug-in for mvc
MVC validation is ok but lots of free & fancy jquery validation plug-in
are available. so how could i incorporate custom jquery validation plug-in
for MVC model validation instead of using default unobtrusive library. can
any one guide me with sample code or give me any link which discuss
everything step-by-step like which classes need to extend to have this
kind of facility. here i attach a picture of jquery fancy validation
plug-in. thanks

why the c++ constructor was not called when it appear as the static member variable?
why the c++ constructor was not called when it appear as the static member
variable?
I had a strange problem ,
declare a static member variable whose name is B class in A class . And
initialize in the cpp file. but the constructor of B class was never
called. I try to use some small test , the test constructor could be
called normally. so it is very strange for our production system.
The code like this , in hpp:
class Test
{
public:
Test()
{
ofstream file("/tmp/wup.txt",ios::app);
file << "wup in test" << endl;
file.close();
}
};
//## An extended personality
class TsdNAExtPersonality : public TsdNAPersonality{
public:
TsdNAExtPersonality(
s_gg62_personRec * gg62Header,
TsdNAFunctionType requiredFunctionType);
private:
static Test test;
public:
TsdNAExtPersonality( string * personalityFile, TsdNAFunctionType
requiredFunctionType);
};
And in another cpp file I initialize with
Test TsdNAExtPersonality::test;
I have tried in several way, but i found all of ways are unusefull.
did not set the variable as member variable but as global variable ==>
also can't output
change the member variable as pointer and change the initialize way as
using new ==> no
the environment is HP-UX ,and the compile is aCC
so my question are :
is there any compile option will influence the variable ? in other words,
all the static variable will not be initialized.
from the standard of C++ it should be called when the library was load,
right?
I put another static int value using the same way, it could be
initialized. but the class constructor is not called , very strange.
is there any mistake in my code ?

Without using for loop how to check whether an element of an array starts with particular string in postgresql
Without using for loop how to check whether an element of an array starts
with particular string in postgresql
In my postgresql query im using a for loop to check whether an element of
an array starts with particular string. If it starts with that particular
string then my query will display the index of that element.
Eg :
FOR i in 1..array_length(array[childrens],2) LOOP -- childrens is the array
IF position('SP' in childrens[i]) != 0 THEN
......
In this loop im checking element by element which is time consuming. So
please can anyone suggest me some idea to do this task and reduce the time
taken.

here is my code for calculating total fare. problem in else part
condition. During running time it will not display the calculation
properly. It was hangs up and shows force close error. any other way to
calculate this (Contsants.minFare+ ((totalKm-Contsants.minDist)
*Contsants.rupeeKm) +(Contsants.cont_WaitingTimeInSec/60)*1) three
parameters separately and display them together at running time. Because i
am going to use this code for taxi booking application. i want to display
the current fare in the display at running time.

In the last bit of the first code, how do I call the print function from
the second code? They're in the same class, and I don't want to confuse

My javascript code fail in other version of browsers except Internet

I need some help where my javascript code fail in Chrome, Firefox, IE6-9
except IE10. Can someone spot any error on this piece of code? What is the
correct syntax to use in this code? See my code below :

$(function Enabler(object) {
var lstWorksheet = document.getElementById('<%=
ddlWorkSheetList.ClientID %>');
var bPreview = document.getElementById('<%= ButtonPreviewFile.ClientID
%>');
var bImport = document.getElementById('<%= ButtonImportData.ClientID
%>');
if (lstWorksheet.selectedIndex != 0) {
bPreview.disabled = false;
bImport.disabled = false;
}
else {
bPreview.disabled = true;
bImport.disabled = true;

Try/Catch inside While in static main method
Try/Catch inside While in static main method
I don't understand the logic to this. If I run this code and enter a
non-int such as the letter f, I get stuck in an infinite loop outputting
the two println's and I am not given another chance to input an int to the
scanner...it just keeps spitting out words to the console.
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);//<<<<<SCANNER HERE
int opponents = 0;
boolean opponentsCreated = false;
while(opponentsCreated == false)
{
try
{
System.out.print("How many players: ");
int tempOpponents = scan.nextInt();
if(tempOpponents > 0)
{
opponents = tempOpponents;
opponentsCreated = true;
}
}
catch(InputMismatchException notAValidInt)
{
System.out.println("Not valid - must be a number greater than
0 ");
}
}
}
But if I simply change the Scanner to be declared inside the while loop,
all of a sudden the program works as expected:
public static void main(String[] args) {
int opponents = 0;
boolean opponentsCreated = false;
while(opponentsCreated == false)
{
Scanner scan = new Scanner(System.in);//<<<<<SCANNER HERE
try
{
System.out.print("How many players: ");
int tempOpponents = scan.nextInt();
if(tempOpponents > 0)
{
opponents = tempOpponents;
opponentsCreated = true;
}
}
catch(InputMismatchException notAValidInt)
{
System.out.println("Not valid - must be a number greater than
0 ");
}
}
}
I honestly just sat here for 2 hours trying to figure out what the heck
was wrong with my program only to find out it was a matter of where I
declared my Scanner even though in both versions of the code the Scanner
was not out of scope. So now I'm really curious why it works this way

ASP.Net Regular Expression Validation of String Length
ASP.Net Regular Expression Validation of String Length
I want to validate if the string entered by user into a text box is at
least 3 characters long. I was using following regex:
\w{3,40}
But it fails if user enters say:
my valid string
I want something that will validate the total string length including
spaces between the words but not at end or beginning of the string.
So following are valid:
"a bc"
"a b c"
"abc"
"a b c"
but following are not:
"a b "
" a "
" bc"

target child id el by knowing the parent class
I have a css class that has a couple of children and I know that the child
ellement that I want to target has an id that ends with 'inner-Ct. I don't
want to assign it my unique id because it will be used in many places.
<div class="totalSummary">

<div id = "form-1406-innerCt"></div> //<---- this is the one I

It's there a way to do this using css?

PostgreSQL NULLable foreign key index optimization
PostgreSQL NULLable foreign key index optimization
PostgreSQL 9.2. Two variations of records can be stored in the following
table. alarmConfigurations entries where ac_p_id is NOT NULL can exist
more than once, but those where ac_p_id is NULL must only exist once
(hence the ac_unique_row_no_port constraint).
As you can see, regular indexes are created on all other foreign keys,
these get scanned a lot. But for ac_p_id...
Is there any particular advantage to creating the non-unique constraint
ac_index_p_id with IS NOT NULL (as opposed to not specifying, like the
others)?
In fact, if I only create ac_unique_row_no_port, will that also be used
for scans where ac_p_id is NOT NULL?

Jquery append not loading javascript for element
I'm making an endless scroll table with movie details and at the movie
storyline I have an easy more/less javascript function(when you click
more,it displays all text and when you click less it hides it back) in
order to make the table look nice. The problem is that after the first 10
movies when the endless scroll kicks in the more/less function doesn't
work for the rest of the movies and it displays the entire story line.
The endless scroll script:
$(document).ready(function () {
$(window).scroll(function () {
if ($(window).scrollTop() == $(document).height() -
$(window).height()) {
$('div#loadingModal').show();
$.ajax({

success: function (html) {
$('div#loadingModal').hide();
if (html) {
$("#postedMovies").append(html);
}
}
});
}

i have just started android and was wondering why its causing this error.
I was thinking it might have something to do with the view that is in the

i have just started android and was wondering why its causing this error.
I was thinking it might have something to do with the view that is in the
activityMain.xml and not in addLine.xml..
Thanks!
