can the order of code make this program faster?
can the order of code make this program faster?
Hi this is my first post, I am learning how to write code so technically I
am a newbie.
I am learning python I am still at the very basics, I was getting to Know
the if statement and I tried to mix it with another concepts(function
definition,input,variables) in order to get a wider vision of python, I
wrote some code without a specific idea of what I wanted to do I just
wanted to mix everything that I have learned so far so probably I over do
it and its not practical, it "works" when I run it.
The question that I have its not about how to do it more efficient or with
less code it is about the order of code in all programming in general.
Here I'll show 2 different order of code that gives the same result with
exactly the same code(but with different order).
on (1) I define a function on the first line.
on (2) I define the same function closer to when I use it on line 5.
which one is faster? is defining a function "closer" to when I need it
impractical for the complexity of larger programs(but does it make it
faster), or defining a function "far" from where I need it makes a larger
program slower when running(but also more practical).
(1)
def t(n1,n2):
v=n1-n2
return abs(v)
a = int(input('how old are you? \n'))
b = int(input('how old is your best friend? \n'))
c=t(a,b)
if a==b:
print ('you are both the same age')
else:
print('you are not the same age\nthe difference of years is %s
year(s)' % c)
input()
(2)
a = int(input('how old are you? \n'))
b = int(input('how old is your best friend? \n'))
def t(n1,n2):
v=n1-n2
return abs(v)
c=t(a,b)
if a==b:
print ('you are both the same age')
else:
print('you are not the same age\nthe difference of years is %s
year(s)' % c)
input()

NSMutableArray with Cyrillic text
NSMutableArray with Cyrillic text
I try to load words from a txt file using following code:
NSURL *filePath = [[NSBundle mainBundle] URLForResource:@"testFile"
withExtension:@"txt"];
NSString*stringPath = [filePath absoluteString];
NSData *drfData = [NSData dataWithContentsOfURL:[NSURL
URLWithString:stringPath]];
NSString *str = [[NSString alloc]initWithData:drfData
encoding:NSUTF8StringEncoding];
Works great, even if I use cyrillic words ("ïðèâåò").
Now, I use following code to add each word as object to my NSMutableArray.
To detect what is a word, I separated them by comma in my testFile.txt
document.
int nLastPoint = 0;
int nCount = 0;
for (int i = 0; i< str.length; i++) {
if ([[str substringWithRange:NSMakeRange(i,
1)]isEqualToString:@","]) {
[lst_wordlist addObject:[[[str
substringWithRange:NSMakeRange(nLastPoint, nCount)]
stringByTrimmingCharactersInSet:[NSCharacterSet
whitespaceAndNewlineCharacterSet]] uppercaseString]];
nLastPoint = i+1;
nCount = 0;
}else{
nCount++;
}
}
int nLength = 0;
for (int i = 0; i< [lst_wordlist count]; i++) {
if ([[lst_wordlist objectAtIndex:i]length]>nLength) {
nLength = [[lst_wordlist objectAtIndex:i]length];
}
}
NSLog(@"%@",lst_wordlist);
Works great, again ONLY if I use english words. With Cyrillic words
doesn't work.
This is my NSLog when I use a cyrillic word.
"\U041f\U0420\U0418\U0412\U0415\U0422",
WORD2,
WORD3,
Any ideas? How can I fix it? I tried to change debugger from LLDB to GDB,
doesn't fix the problem.

webview doesnt work ajax jquery on jelly bean
My android web app doesnt work on click jquery ajax. I don't know what
code should i post because .. okay let me tell what i did try. This is
link to my web (forum in malays) http://debatremaja.com/mb/cadang_tajuk .
and this is app in google play store
https://play.google.com/store/apps/details?id=com.debatremaja&hl=en .
Problem + Thumbs up sign in web link above will run
$(".vote_active").click(function(){
var topic_id = $(this).data("topic-id");
var linkto= linktodbcontroller+"insert_vote_by_id_n/"+topic_id;
//window.location.href = linkto;
$(this).next(".sum").load(linkto);
// simple prevent 2nd clicked
$(this).removeClass("clickable");
$(this).css("color","#0c0");
$(this).off("click");
});
And that working fine on
pc web browser , firefox and chrome tested
on mobile browser ( android 4.2.2 cyanogemod firefox)
my app (link above) on android 2.3 emulator
Maybe ajax not working in webview ?
so i did change android code to
loadUrl("w3school jquery demo") // Sorry, i cannot post more than 2 links
But the button in w3school works fine.
Problem only happend on my app webview.
Thanks in advance because i had experiance get my question answered less

Definitive C Input/Output Guide
Since the semester recently started a lot of similar questions regarding
IO in C (and C++) keep pouring in and the answers are often the same:
while(!feof()) is bad, use fgets() instead of scanf(), etc.
Do you think a community wiki is needed so all the duplicate questions
could be directed to that single answer? Or do you think they are still
sufficiently different so that those who ask would benefit from a question
tailored to their demands? Some just downvote and comment suggesting
posting on homework.stackexchange.com, but this doesnt't help.
After reading How should duplicate questions be handled? and What's the
etiquette for answering two similar questions? it seems to boil down to
the question how similar are two posts to be considered duplicate.
If you feel that most of the questions were indeed duplicates and that
this could grow into a community wiki page, please post your tricks of the
trade on IO in C including use, best practices, no-nos, notes on history
or implementation details and links to useful resources.

Url rewrite is not working in some cases with XAMPP in Windows 7
Url rewrite is not working in some cases with XAMPP in Windows 7
I have a PHP website hosted at localhost on my Windows 7 PC, running XAMPP
1.8.2.
And I have rewrite rules as below:
Options -Indexes +FollowSymLinks
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?rt=$1 [QSA,L]
</IfModule>
To rewrite the URL so it will always go into something like:
http://mysite.com/index.php?rt=[controller]/[action]/[params]
It works prefect until I found it failed when processing url like:
http://mysite.com/error/xxx. It returns a 404 status other than goes to
http://mysite.com/index.php?rt=error/xxx.
I carefully checked my PHP code and I am sure it is not the cause, and I
upload my website to a remote server and everything is fine. So I am
pretty sure something is not properly configured in my XAMPP (Apache),
that makes the /error/xxx request was treated differently.
Also I found visiting http://mysite.com/error/ gives me 403 but
http://mysite.com/[something_else]/ is fine.
Just in case, I paste my vhost.conf here as well:
<VirtualHost *:80>
DocumentRoot "/xampp/htdocs"
ServerName localhost
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "E:\htdocs\mysite.dev"
ServerName mysite.dev
</VirtualHost>
And related httpd.conf:
<Directory "E:\htdocs">
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Require all granted
</Directory>
Any help is appreciated!

Asp.net web api and mvc - avoiding duplication
Asp.net web api and mvc - avoiding duplication
I am exploring ASP.Net web Api and I am trying to use to create a web page
to basically provide option to edit and display some data from DB(MySQL)
with some modifications. I also want to provide a REST Api that would be
used by mobile app. Now I can do this with the ApiController(to provide
REST api) and then the MVC Controller which renders the model(using View
method). This works but there is lot of duplication between the API and
the MVC controller. Is there a design pattern or something that avoids the
redundancy?
I understand that API controller has to return JSON and the MVC controller
has to return the Model for the view.

How should we parse a specific JSON date format in the ASP.NET C# application?
How should we parse a specific JSON date format in the ASP.NET C#
application?
We are using a third-party vendor for one of our modules in an application
The Web Service Endpoints are provided by a third-party vendor.
For one of the Web Service Endpoints that deals with posting Comments,
our ASP.NET C# web application will get back some JSON data.
I am using James Newton-King Json.NET for processing JSON data.
Within the JSON Data that we receive from the Web Service of the
third-party vendor, we get the following date which is associated with
time that the comment was posted:
\"date_created\": 1375206707,\r\n
Therefore, I created an ASP.NET DataContract C# class that would
correspond to the JSON data that we are receiving.
Furthermore, I have the following DataMember in the C# class that would
correspond to the date of creation associated with the Posted Comment:
[DataMember(Name = "date_created")]
public string ViaFouraCommentCreationDate { get; set; }
Please make suggestions as to how I should parse the following JSON date
format
in the ASP.NET C# world( possibly also involving the James Newton-King
Json.NET):
\"date_created\": 1375206707,\r\n

How can I relay mail to multiple SMTP servers?
How can I relay mail to multiple SMTP servers?
We want to use Google Apps for Domains as our email service but the
"corporate" office want's the emails in Exchange. I would like to set up a
relay (is that the proper term) to send any incoming mail to both, Google
and Exchange. That way, we can use Gmail for our daily communication (both
sending & receiving) and the "corporate" people are happy getting a copy
of our incoming stuff.
Or is this completely insane? :)
Thanx!

DateTime problems when movign to production environment
DateTime problems when movign to production environment
I have several forms within my MVC app that have date values which are
chosen via a datepicker tool. This works well when debugging locally but
on deployment to the cloud environment my dates are not being correctly
converted. I have the following code:
string[] uploaddate = form.GetValues("uploaddate");
string[] expirydate = form.GetValues("expirydate");
This gets the date as 31/08/2013 etc. and from here I was converting to
DateTime as follow:
Convert.ToDateTime(uploaddate[0]);
Convert.ToDateTime(expirydate[0]);
When I deploy to the Azure server I receive the following error:
String was not recognized as a valid DateTime.
I think that the instance image has a culture of US while my application
was designed in UK format, how can I go around this problem so that the
information is saved to the database irrespective of the culture of the
user

To check if paranthesis are balanced- Without stack
Suppose I have a very huge file and I want to check if parenthesis are
balanced. I can't use stack, right? Because it'd result in a stack
overflow. What approach I can use?

C++ stringstream, if word is numeric, divide by two
C++ stringstream, if word is numeric, divide by two
I am fairly new to programming and have to create a program which reads
the prompt: "I have 8 dollars to spend." It then needs to print out with
each word on a separate line, and then if any of the strings is numeric,
it needs to be divided by 2. Therefore it should end up printing out as:
I
have
4
dollars
to
spend.
I have managed to do everything, except finding the numeric value and
dividing it by 2. So far I have this:
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main()
{
string prompt;
string word;
cout << "Prompt: ";
getline(cin, prompt);
stringstream ss;
ss.str(prompt);
while (ss >> word)
{
cout << word << endl;
}
return 0;
}
After looking through various other posts, I cannot manage to get this to
work. I'm assuming its an if/else statement within the while loop along
the lines of, if numeric, set int num to num / 2 then cout << num <<
endl;, else cout << word << endl;, but I can't figure it out.
Thanks in advance.

Contoso University part 5, reading related data without passing parameter
Contoso University part 5, reading related data without passing parameter
I am walking through Contoso University ASP.NET MVC example part 5.
http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application
I can't quite understand how the id parameter was passed to the
controller/view when I select a course taught by the instructor. In the
view, the section to display the courses is as following:
@if (Model.Courses != null)
{
<h3>Courses Taught by Selected Instructor</h3>
<table>
<tr>
<th></th>
<th>ID</th>
<th>Title</th>
<th>Department</th>
</tr>
@foreach (var item in Model.Courses)

}
<tr class="@selectedRow">

item.CourseID })*
</td>
<td>
@item.CourseID
</td>
<td>
@item.Title
</td>
<td>
@item.Department.Name
</td>
</tr>
}
</table>
}
The Controller Index function is as following:
public ActionResult Index(int? id, int? courseID)
{
var viewModel = new InstructorIndexData();
viewModel.Instructors = db.Instructors.Include(r =>
r.OfficeAssignment)
.Include(r => r.Courses.Select(c => c.Department))
.OrderBy(i => i.LastName);
if (id != null)
{
ViewBag.InstructorID = id.Value;
viewModel.Courses = viewModel.Instructors.Where(
i => i.InstructorID == id.Value).Single().Courses;
}
if (courseID != null)
{
ViewBag.Courses = courseID.Value;
//eager loading
//viewModel.Enrollments = viewModel.Courses.Where(
// i => i.CourseID == courseID.Value).Single().Enrollments;
//equivalant, but explicit loading
var selectedCourse = viewModel.Courses.Where(x => x.CourseID

Pass a reference to a reference
Pass a reference to a reference
I think it's illegal to pass a reference to a reference in C++.However
,when I run this code it gives me no error.
void g(int& y)
{
std::cout << y;
y++;
}
void f(int& x)
{
g(x);
}
int main()
{
int a = 34;
f(a);
return 0;
}
Doesn't the formal parameter of g() qualify as a reference to a reference ??

Template is re-rendered even though there is no data change
Template is re-rendered even though there is no data change
I'm struggling with an issue that I will explain giving a simple demo.
There's following very simple document in People Collection.
{
"_id" : "vxmLRndHgNocZouJg",
"fname" : "John" ,
"nicks" : [ "Johnny" , "Jo"]
}
Now let's consider following templates. Basically I display username and a
list of nicknames with input field for adding more nicknames.
<head>
<title>test</title>
</head>
<body>
<br/>
</body>
<template name="name">
<input type="text" value="{{fname}}"/>
</template>
<template name="nicks">
<div>
no nicks yet
{{/each}}
<input type="text" name="nicks"/>
<input type="submit"/>
</template>
My client javascript code is as follows:
Template.name.fname = function() {
return People.findOne({"fname" : "John"},{
transform : function(doc) {
return doc.fname;
}
});
}
Template.name.rendered = function() {
console.log('Template "name" rendered!');
}
Template.nicks.nicks = function() {
var john = People.findOne({"fname" : "John"});
if(john) return john.nicks;
}
Template.nicks.events({
'click input[type="submit"]' : function () {
var johnId = People.findOne({"fname" : "John"})._id; // demo code
People.update(johnId,{
$addToSet : {
nicks : $('input[name="nicks"]').val()
}
})
}
});
My problem is that after adding nickname (update of nicks field in a
document) template name is re-rendered (I know because I console.log it).
When I query People collection to provide data for name template I use
transform option so changes in nicks field shouldn't have impact on name
template.
Meteor docs supports this:
Cursors are a reactive data source. The first time you retrieve a cursor's
documents with fetch, map, or forEach inside a reactive computation (eg, a
template or autorun), Meteor will register a dependency on the underlying
data. Any change to the collection that changes the documents in a cursor
will trigger a recomputation.
Why template name is re-rendered then?

mongodb - one document in many collections
mongodb - one document in many collections
i'am looking for a good solution on MongoDB for this problem: There are
some Category's and every Category has X items. But some items can be in
in "many" Category's!
I was looking for something like a symbolic link on Unix systems but i
could't not find it.
What i thought is a good idea is: "Category1/item1" is the Object and
"category2/item44232" is only a reference to "item1" so when i change
"item1" it also changes "item44232".
I looked into the MongoDB Data models documentation but there is no real
solution for this.
Thank you for your response !

How to freeze columns and rows in WPF Grid
How to freeze columns and rows in WPF Grid
I'd like to "freeze" the columns and rows in WPF.
I want to implement a table (state machine), where in the first row are
states and in first column are commands. The rest of the cells are filled
with events. To improve usability, I'd like to keep the first row and
first column visible all the time, so even at the very bottom of the table
the states and commands are visible.
The DataGrid offers this kind of functionality but DataGrid cells don't
look flexible enough. I'd like to use Grid. The ScrollViewer is basically
what I need, but i haven't figured out how to use it for multiple Grids at
the same time.
Is there any way to freeze first row and first column (at the same time)?

ColdFusion 10 REST API UTF-8 Characters
ColdFusion 10 REST API UTF-8 Characters
I'm using ColdFusion 10's new REST API and I'm having trouble with UTF-8
characters. It seems that ColdFusion 10's new REST API completely mangles
non-ASCII characters. Is there a way around this?
For example, let's say I have an endpoint like this:
<cfcomponent rest="true" restpath="/widgets" produces="application/json">
<cffunction name="echo" access="remote" httpmethod="PUT"
returntype="string">
<cfreturn GetHttpRequestData().content />
</cffunction>
</cfcomponent>
This endpoint simply responds with exactly what was sent in the request.
Here is my request:
PUT http://www.mycompany.com/rest/v1.0/widgets HTTP/1.1
User-Agent: Fiddler
Host: www.mycompany.com
Content-Length: 15
こんにちは
Here is the response I get:
HTTP/1.1 200 OK
Content-Type: application/json
Server: Microsoft-IIS/7.5
Date: Mon, 26 Aug 2013 23:59:09 GMT
Content-Length: 37
ã�"ã‚"ã�«ã�¡ã�¯
Note how the response is completely different from the request.
To be 100% certain that this is a problem with the request being mangled
by ColdFusion and not a problem with the response being generated by
ColdFusion, I enhanced the endpoint to also log the request body into a
database, and sure enough, it was already mangled.

Unable to download .mp4 movies via Internet download Manager installed using PlayOnLinux in Ubuntu 12.10
Unable to download .mp4 movies via Internet download Manager installed
using PlayOnLinux in Ubuntu 12.10
I am a newbie in Ubuntu and installed the 12.10 version. I visited several
sites and did all things I was "supposed" to do after installing Ubuntu
12.10.
I love movies a lot and I am addicted to downloading them. I tried
installing Uget along with flashgot but they both seem slow to download. I
miss my Internet Download Manager aka IDM, which I used for Windows, since
it was very fast. Luckily, I came across PlayOnLinux which can help to
install and use non-ubuntu applications.
For my case (of movies), I came across this website on how to use
PlayOnLinux aka POL to download anything. It really work as I've been
browsing and getting +ve feedbacks. I followed the instructions and at the
very end, when trying to download the movies, a POL dialogue appears
saying There is nothing installed
torun.91ac8608ee713b8da469a43046e864d95f4483b9 files. The number varies
according to the movie.
Can someone please tell me what am I supposed to install to run those
files in PlayOnLinux please?
I really do appreciate as I know there are ubuntu gurus in this forum.
Thank you.

upload to the arduino so that it sends coordinates to the laptop without
being connected via USB.
Here is the GPS Module:

I want to sync the Mail app on my iPhone5 with the Mail app on my Macbook
I want to sync the Mail app on my iPhone5 with the Mail app on my Macbook
I'd gotten an iPhone 5 earlier on in the year and managed to set up my
Hotmail/Outlook account with no hassles. This week I bought an 11" Macbook
Air and setting up the same account on my Macbook is far more complicated:
the smtp server settings for Outlook don't seem to work! So basically I
can receive emails, but cant send them. I was wondering if there was a way
to just sync the email account which is already on my phone, with the Mail
app on my laptop?

Firefox adds 5mm additional margin to @page directive
Firefox adds 5mm additional margin to @page directive
I am writing a CSS style sheet for printing a web page and encountered the
following problem: Firefox adds additional margin to a @page directive.
Here is an example.
HTML:
<html>
<head>
<title>CSS Print Test</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="content">
Print Me!
</div>
</body>
</html>
CSS:
html,
body,
div {
margin: 0;
padding: 0;
}
#content {
border: 1px solid;
}
@page
{
size: A4 portrait;
margin: 30mm 30mm 30mm 30mm;
padding: 0;
}
This should give the page a margin of 3 cm on each side. It works for
Chrome (29.0) and IE 10 but not for Firefox (21.0). When printing the page
with Firefox the margin on each side is something like 35mm.
Is there a simple solution or at least an explanation for this behavior?

Can we say that using "pass by reference" is always better than "pass by value"?
Can we say that using "pass by reference" is always better than "pass by
value"?
In C# or php or other languages, there are 2 ways to pass a value to a
function, pass it by value and pass it by referece.
Pass parameter by value make the value copied in the function, so this
need a extra memory space although the memory space will be reclaimed
after running outside the function.
But passing parameter by reference no need to copy a value, it's save the
memory. From this perspective, can we say that using "pass by reference"
is always better than "pass by value"?

How to apply a jQuery function to a child page in an iframe?
How to apply a jQuery function to a child page in an iframe?
Here's a brainteaser:
I have an iframe in a window, and a navbar that links to it:
<div class="nav">
<a href="link.html" target="iframe-content" id='debug">#Debug<a>
</div>
<iframe name="iframe-content" src="page.html"></iframe>
I've then got a simple jQuery function to inset a class when a link in the
nav is clicked.
$(window).load(function() {
$("#debug").click(function() {
$('body').toggleClass("debug");
});
});
Now my question is how do I get the toggleclass to apply to the inline
frame (page.html) and not the parent page?

Create a custom table in java
Create a custom table in java
I would like to create a table looking like this but with the titles
in-sync with the table:
Any tips on how make the columns being aligned with the rows and also
allow auto resize in x-axis? For this I used GridBagLayout. Also tried
with JTable but had problems to customize it to hide all default JTable
components(like in my picture).
public class MyTableExample extends JFrame {
public MyTableExample(){
JPanel contentPanel = new JPanel(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.weightx = 1;
c.fill = GridBagConstraints.HORIZONTAL;
contentPanel.add(getTitles(),c);
c.gridy = 2;
contentPanel.add(getRow(),c);
c.gridy = 3;
contentPanel.add(getRow(),c);
// MainPanel: Helps positioning the contentPanel
JPanel mainPanel = new JPanel(new GridBagLayout());
c.weighty = 1;
c.anchor = GridBagConstraints.NORTH;
c.insets = new Insets(20,20,20,20);
mainPanel.add(contentPanel,c);
this.add(mainPanel);
this.pack();
this.setVisible(true);
}
private JPanel getRow(){
JPanel rowPanel = new JPanel(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.weightx = 1;
c.weighty = 1;
c.fill = GridBagConstraints.HORIZONTAL;

I would like to create a table looking like this but with the titles
in-sync with the table:
Any tips on how make the columns being aligned with the rows and also
allow auto resize in x-axis? For this I used GridBagLayout. Also tried
with JTable but had problems to customize it to hide all default JTable
components(like in my picture).

How do I get the remote IP-Address of clients connecting to a rebol3 based server?
How do I get the remote IP-Address of clients connecting to a rebol3 based
server?
Atm I'm playing with Carl's basic tcp test scripts and would like to know:
"How to get the IP-Address of clients connecting to the server?" Any
ideas? I tried to probe a client subport at the server-side but it doesn't
show the remote-ip. Can someone give me hints on gathering that
information. I know how it works within rebol2, but I'm not familiar with
the R3 port model.

sendmail is not delivering messages to recipients
sendmail is not delivering messages to recipients
I have run into a number of problems getting sendmail to work. None of the
solutions I've tried have worked.
First: sendmail was hanging for 60 seconds and then not sending the email.
To solve this, I used suggestions from the web to set my /etc/hostname to
a fully qualified domain name (FQDN) and then put that in /etc/hosts as
well. This did get rid of the hanging, but I still never receieve any
emails sent from sendmail.
Second: Installed postfix
This did not fix the issue. Sending an email via sendmail or mail at the
command line both fail. Example:
echo "a message" | sendmail someemail@gmail.com
echo "a message" | mail someemail@gmail.com
Both commands return instantly without error, but no email is ever
recieved at the gmail account.
I made sure a port was open at 25 in the router as well (although this
shouldn't be an issue as Thunderbird can send emails behind the router).
I need to get this working for PHP but cannot figure out where in the many
steps from the program to the remote email server it is failing. How would
I figure this out?

Can someone help me improve speed?
Can someone help me improve speed?
As of now this generates a dictionary full of points that a player can
move to and the cost of that move. My problem is that it takes ages to
process.
I understand that although a square is already checked as added my method
checks the same square again, but when I dont do this than the moveable
area gets all screwed up and it does not return what it should.
Can i get some pointers on how to speed this up, Please include
examplecode. I was thinking about a few extra threads but that would leave
me processing this in quadrents and if i need to form movements around an
object on the grid then I dont think ill be able to build off of cells
belonging to other threads.
This code works right now, it is just slow as snot and its unacceptable
for my program.
Please note that This is not path finding, I am only looking for all
possible moves, not the shortest way to get to a spot.

Animating the mask for a UIView
Animating the mask for a UIView
I can create a mask like this:
CALayer *mask = [CALayer layer];
mask.contents = (id)[[UIImage imageNamed:@"mask.png"] CGImage];
mask.frame = CGRectMake(0, 0, 10, 10);
self.content.layer.mask = mask;
And this will correctly reveal the top left 10 pixels of my content
(because mask.png is just a black image). However I want to animate the
mask to reveal the rest of the content:
[UIView animateWithDuration:3.0
animations:^{
mask.frame = self.content.bounds;
}
completion:^(BOOL finished){
}];
The problem is that there's no animation. The entire content gets
displayed immediately. Why does this happen, and how can I animate the
mask so that the content is revealed from the upper left?

We are using polycom video conferencing solution with RMX 2000 as
multiparty confrlerencing unit, DMA 4000 as gatekeeper to register devices
and also act as SIP proxy. RPAD acts for firewall traversal. Except RPAD
all other servers are kept in MZ. Rpad is in DMZ. The end terminal used is
of Lifesize Team 220. Now the situation is I am able to make call(using
H.323) from internet to the end terminal but not the reverse, that is from
end terminal to devices kept in internet. As per the network guy the
packets have not been initiated at all from the end terminal. So probably
its some configuration issue of the rpad or dma or rmx. Need some help in
this. What could be the possible issue/solution?

Adding a Third column of data in Mathematica
Adding a Third column of data in Mathematica
I have a very large table of data something like:

I would like to add x to every element so it would be

This seems to me like it should be rather trivial but I have not been able
to find a solution.
I would appreciate any help, Ben

i added tika jar file.
Give me some idea to fix this issue.
i am uploading file using upload from then after getting uploaded file i
am using Apache tika top extract content,metadata from uploaded file and
applying but some error is coming
have a look of my playframework controller code :
public static Result upload() {
MultipartFormData body = request().body().asMultipartFormData();
FilePart picture = body.getFile("doc");
if (picture != null) {
String fileName = picture.getFilename();
int eof = fileName.lastIndexOf('.');
String ext = fileName.substring(eof + 1);
file = picture.getFile();
InputStream is;
try {
is = new FileInputStream(file);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
Parser ps=new AutoDetectParser();
BodyContentHandler bch=new BodyContentHandler();
Metadata metadata=new Metadata();
try {
ps.parse(is, bch, metadata, new ParseContext());
} catch (IOException | SAXException | TikaException e) {
e.printStackTrace();
}
String sw=bch.toString();
return ok(sw+" entity extracted and saved" + ext);
}else {
flash("error", "Missing file");
return redirect(routes.Application.index());
}
but when i am running this web application i am using commands:

c# multi line strings allowing variable calling
c# multi line strings allowing variable calling
I have googled but cannot find an answer for this question:
I know about multi-line strings in c#. But how can I create a string like:
string temp = @"DECLARE @rolename varchar(max)
SET @rolename ='***'
EXEC sp_addrolemember N'db_execute',@rolename"
* represents there I have to delcare a variable having some value like
(object.variable).
Is this possible??

HLS Video Doesn't Upscale in Browser
HLS Video Doesn't Upscale in Browser
I am attempting to get an HLS stream to work in a browser (Webkit).
It first appears to work, the video starts, playing the
medium(480p)stream. Unfortunately, the stream quality doesn't improve over
time as it should.
Does anyone have a source that discusses either a tool or simple method to
manage the changes of these different streams? or.. Perhaps a direction in
which to follow so I can write my own controller for switching between the
streams?
Thank you for you help.

MarkLogic 5 return elements wrapped in CDATA
MarkLogic 5 return elements wrapped in CDATA
I'm trying to get MarkLogic 5 to return items wrapped in a CDATA tag but
it simply refuses to. Doesn't barf, just doesn't do it. Am I barking up
the wrong tree using: -
xquery version "1.0-ml";
declare option xdmp:output "cdata-section-elements = text";
<text><![CDATA[\begin{eqnarray}
\fl {R}_{\mathrm{sw}(e)}=\nonumber\\ \fl \biggl \{
\frac{3{L}_{1}{L}_{2}{Q}_{\mathrm{after}}}{1 2{k}_{h}{A}_{h}\Delta
T({L}_{1}+{L}_{2})-({L}_{1}+{L}_{2})^{2}({Q}_{\mathrm{before}}-{Q}_{\mathrm{after}})}-1\biggr
\} \nonumber\\ \times
~\frac{{L}_{1}{L}_{2}}{({L}_{1}+{L}_{2}){k}_{h}{A}_{h}}-{R}_{j}-{R}_{\mathrm{CNT}},
\end{eqnarray} ]]>
</text>
Simply returns without the CDATA tag which is contrary to all
documentation I can find. I've tried returning the content several ways,
e.g., xdmp:quote but as I need to parse the content using XSLT at the
other end it really needs to be wrapped in a CDATA element.
The content is normally deeply nested but I've simplified here for ease.
Any clues?

Definition of weak solutions
Definition of weak solutions
Why are weak solutions defined like:
A function $u \in H^1(\Omega)$ is a weak solution of $$ Lu=div(A\nabla
u)+b\cdot\nabla u+cu=f+divF, in \Omega $$ if $$ \int_\Omega \nabla
\phi\cdot (A\nabla u-F)dx=\int_\Omega\phi(b\cdot \nabla u+cu-f) dx $$
holds for every $\phi \in C_0^\infty(\Omega).$
I mean, we define this new notion "weak solutions" in order to generalize
classical solutions. Then we just need one purpose which is "classical
solution $\Rightarrow$ weak solution" and if everything is sufficiently
smooth, then it follows that a weak solution is automatically a classical
one. If this is our motivation to define weak solutions, then there would
have tons of methods to do.
My point is why this type of definition of weak solutions is so important.
Is there any other motivations like from geometry or other subjects to
make this definition so outstanding and is there any other type of
definitions of generalized solutions?

Associate SSL certificate for SQL Server which does not use the FQDN
Associate SSL certificate for SQL Server which does not use the FQDN
We would like to connect securely to SQL 2008 R2 over the internet for
reporting purposes. Speed is not a huge concern for these smaller data
sets, and users are going to be using simple reporting programs (e.g.
Access) that require ODBC connections, rather than an API of sorts. In
this scenario we have a SQL Server running on a local network (e.g.
sql.mydomain.local) which is being accessed from the outside world via NAT
(e.g. sql.mydomain.com, port xyz). This works fine with no security,
however we need to encrypt the connections. The simple way to do that is
to add SSL to the SQL server. Here is where I run into issues though:
If I get a certificate for the external name (sql.mydomain.com), SQL
Server refuses to see or use the external SSL cert as it is not the
servers name or FQDN, since it is configured locally (per
http://technet.microsoft.com/en-us/library/ms191192.aspx). Manually adding
the cert via HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL
Server\MSSQL.x\MSSQLServer\SuperSocketNetLib doesn't seem to change that
behavior for me.
If I use a self-signed certificate from the domain controller, I'm able to
see and use the cert in SQL. However external connections obviously
complain that the cert is not trusted. If I add the domain controller as a
trusted publisher, then SQL complains that the server name doesn't match
the certificate name when I attempt to connect to it.
All of the paths forward seem a little wonky: 1. Setup a local domain for
only that server with the public name (e.g. mydomain.com) and add the
machine there so that the FQDN matches the external certificate generated
from a trusted publisher, hopefully SQL will see and use the cert then. 2.
Have the users modify their hosts file to create a cname of
sql.mydomain.local to sql.mydomain.com.
Am I missing something in my understanding so far? Is there any way to get
around SQL's limitations regarding use of a cert which is not the FQDN? If
I purchase a certificate for sql.mydomain.com with a Subject Alternative
Name of sql.mydomain.local, will SQL see and use it?

around SQL's limitations regarding use of a cert which is not the FQDN? If
I purchase a certificate for sql.mydomain.com with a Subject Alternative
Name of sql.mydomain.local, will SQL see and use it?

IMG won't show on remote site
IMG won't show on remote site
I have a webpage where the images are not being found (running chrome). I
synced the remote directory with my local one, so all files should be
identical, however I can see the images locally but not on the remote
site. Can anyone explain why?
I have the following directory where my index.html is:
icons/circle/*.png, where * is some generic social media i.e. (facebook,
twitter, etc.)
using this code to show it on html
<img class="social-media" src="icons/circle/facebook.png">
But it only shows when I view my webpage locally, not when everything is
uploaded to the server.

Parsing a text file into a list in python
Parsing a text file into a list in python
I'm completely new to Python, and I'm trying to read in a txt file that
contains a combination of words and numbers. I can read in the txt file
just fine, but I'm struggling to get the string into a format I can work
with.
import matplotlib.pyplot as plt
import numpy as np
from numpy import loadtxt
f= open("/Users/Jennifer/Desktop/test.txt", "r")
lines=f.readlines()
Data = []
list=lines[3]
i=4
while i<12:
list=list.append(line[i])
i=i+1
print list
f.close()
I want a list that contains all the elements in lines 3-12 (starting from
0), which is all numbers. When I do print lines[1], I get the data from
that line. When I do print lines, or print lines[3:12], I get each
character preceded by \x00. For example, the word "Plate" becomes:
['\x00P\x00l\x00a\x00t\x00e. Using lines = [line.strip() for line in f]
gets the same result. When I try to put individual lines together in the
while loop above, I get the error "AttributeError: 'str' object has no
attribute 'append'."
How can I get a selection of lines from a txt file into a list? Thank you
so much!!!

How can I show text touching div borders?
How can I show text touching div borders?
I have a DIV. Inside that DIV I put some some text. The div is positioned
absolutely. It has style="border:1 px solid black" so it shows as a nice
rectangle. Now within this rectangle I want to show text which touched
either top or bottom border (whichever is easier):
The thing is: 1) I don't want to underline the text- this is not the issue
2) I don't want to manually position the text within the DIV
3) The point is: I set the position of the DIV and the text automatically
touches the border (top or bottom border)- no matter what font-family or
font-size I set.

Computation of the mean of a random variable to estimate algorithm complexity
Computation of the mean of a random variable to estimate algorithm complexity
I made an incremental algorithm which I would like to evaluate the
complexity. The algorithm works with a sliding window of size n.
To study the complexity, the window is considered full and the data
present are ${x_{1},...,x_{n}}$ . They are assumed to be random, i.i.d,
but with no assumption regarding their distribution. In particular, they
are not necessarily bounded. Finally, the most recent data is $x_{n+1}$.
The complexity of the algorithm depends on the distance from $x_{n+1}$ to
its "nearest lower value" $x_{l}$ whose index is $l=\max\left\{
k\in\{1...n\}\;st\;x_{k}<x_{n+1}\right\}$. The distance $d$ is then
$d=n+1-l$.
$d$ is obviously a random variable, and I would like to determine its
mean, which would give the algorithm complexity.
I first thought $d$ was a geometric variable with argument 1/2 since
$P\left(x_{n+1}\geq x_{n}\right)=1/2$ (which I cannot prove either), so
$E\left[d\right]=2$ but it is not the case. Indeed, $x_{n+1}$ and $x_{n}$
are not independent so $d$ does not follow a geometric law. Moreover, I
did some experiments on Excel to compute $E\left[d\right]$ using different
distributions and it seems it does not depend on the distribution of the
$x_{i}$ but on $n$ (I can not post the image, it confirms this result).
Below is a track I have tried to follow to determine $E\left[d\right]$
which proved unsuccessful:
$E\left[d\right]=\sum_{k=1...n}kP\left(d=k\right)$
and
$\begin{eqnarray*} P\left(d=k\right) & = & P\left(x_{n-k}<x_{n+1}\cap
x_{n-k+1}\geq x_{n+1}\cap...\cap x_{n}\geq x_{n+1}\right)\\ & = &
\forall\lambda_{1},\lambda_{2}\in\mathbb{R}\int_{\lambda_{1}<\lambda_{2}}P\left(x_{n-k}<\lambda_{1}\cap
x_{n+1}\in\left[\lambda_{1};\lambda_{2}\right]\cap\bigcup_{j=n-k+1...n}x_{j}\geq\lambda_{2}\right)d\lambda_{2}d\lambda_{2}\\
& = &
\int_{\lambda_{1}<\lambda_{2}}P\left(x_{n-k}<\lambda_{1}\right)P\left(x_{n+1}\in\left[\lambda_{1};\lambda_{2}\right]\right)\sum_{j=n-k+1...n}P\left(x_{j}\geq\lambda_{2}\right)d\lambda_{2}d\lambda_{2}\\
& = &
\int_{\lambda_{1}<\lambda_{2}}F_{X}\left(\lambda_{1}\right)\left(F_{X}\left(\lambda_{2}\right)-F_{X}\left(\lambda_{1}\right)\right)\sum_{j=n-k+1...n}\left(1-F_{X}\left(\lambda_{2}\right)\right)d\lambda_{2}d\lambda_{2}

Fibonacci sequence in Java using for statements
Fibonacci sequence in Java using for statements
I tried making a Java program executing the Fibonacci sequence.
Here's my code:
import java.io.*;
public class Fibonacci{
public static void main(String[]args){
BufferedReader Data=new BufferedReader (new
InputStreamReader(System.in));
int ctr1=0;
int ctr2=0;
int num1=0;
int num2=0;
int num3=0;
try{
System.out.println("How many numbers would you want to see?");
ctr2=Integer.parseInt(Data.readLine());
for(int ans=0; ctr1==ctr2; ctr1++){
num1++;
System.out.println(num2 + "\n" + num1);
ans=num1+num2;
System.out.println(ans);
ans=num3;
}
}catch(IOException err){
System.out.println("Error!" + err);
}catch(NumberFormatException err){
System.out.println("Invald Input!");
}
}
}
Obviously, I'm a beginner in Java and I don't know how to properly use the
for statement. Would somebody be kind enough to make my code work? Or
maybe make a way shorter code that works. I'm a beginner so be cool.
Thanks :)

Run Applescript with Growl 2.1 Rules
Run Applescript with Growl 2.1 Rules
Currently, I have a flow set up that results in a file -- 'cb.txt' --
being added to my Dropbox. I get a Growl notification with the Application
Name 'Dropbox' and the Note Title 'cb.txt added'. I want the 'cb.txt
added' notification to run an applescript that will copy the text from
cb.txt to my clipboard. The rules for Growl's notification can be found
here.
Here is the applescript I want to run (when I run it by itself via
Applescript, it successfully adds the contents of cb.txt to the
clipboard):
set the_file to "HardDrive:Users:Me:Dropbox:Folder:cb.txt"
set the_text to (do shell script "cat " & quoted form of (POSIX path of
the_file))
set the clipboard to the_text
I have saved this file to ~/Library/Application
Scripts/com.Growl.GrowlHelperApp as an apple script. I have also saved
another version using this code:
using terms from application "Growl"
on perform action with notification
ignoring case
if notification's app name is Dropbox then
if notification's note title contains "cb.txt added" then
set the_file to "Macintosh
HD:Users:Caleb:Dropbox:Apps:CBApp:cb.txt"
set the_text to (do shell script "cat " & quoted form
of (POSIX path of the_file))
set the clipboard to the_text
end if
end if
end ignoring
end perform action
end using terms from
The previous script does not do anything when run. I have this saved as
Rules.scpt:
using terms from application "Growl"
on evaluate notification with notification
--Rules go in here
--Ultimately return what you want Growl to do with the notification
end evaluate notification
end using terms from
Obviously, I'm a bit stuck. If anybody could give me advice on how to get
my working applescript code to run when I receive a specific Growl
notification, I would appreciate it!

Flot Bar Graph Align Bars with X-Axis Labels
Flot Bar Graph Align Bars with X-Axis Labels
Hello I am trying to plot a bar chart with 31 days data. However when I
plot it, the label for each data is not directly in the center below its
bar, when i set the bars to
align: "center"
, the first bar and last bar gets cut into half.
Here is the jsfiddle: http://jsfiddle.net/3T6qc/
How do I set it so that i see the full bars and have the labels directly
below in the center? Take note that I am using flot as the plotting
library.

Different types of lists
Different types of lists
Hello I am studying Java and I am just confused about a question that
keeps coming up in my exams.
We are told to use a class for our collections.
Usually in my main class I just make an arraylist of the type I need like
bank accounts or whatever. But I think we are supposed to make a class for
all our data. I tried this and made them static and have the class
abstract because I don't need to make copies of the class itself.
What I want to know is why don't people just make a list type that can do
everything an arraylist and list can do in one, why is there different
types? What are the benifits of having different types? Ps does a
collection just mean a class for all your data?

int GetQuotesEx(LPCTSTR pszTicker, int nPeriodicity, int nLastValid, int
nSize, struct Quotation* pQuotes, GQEContext* pContext) {
const RecentInfoMap::const_iterator it = g_mapRecentInfo.find(pszTicker);
if (it == g_mapRecentInfo.end()) {
g_quote->RegisterQuote(_bstr_t(pszTicker), _bstr_t("*"));
return nLastValid + 1;
}
}
I don't know why this bug happens. I can provide additional info if needed.
Salesforce - Custom page for new related list of Custom Object
Salesforce - Custom page for new related list of Custom Object
I have custom objects A and B. The relationship between A & B is set using
a custom object C, with object A & B (master detail) as fields of C.
I have created a custom lookup page to bind object B (to A) which is set
as related list to Object A.
I want to invoke the custom page when I click on New button in the related
list. How can I achieve this?
Thanks.

C# LuaInterface class operators
C# LuaInterface class operators
I'm using LuaInterface in C# and I "exported" some custom C# classes to be
used in Lua. For instance:
local myVector = Vector2(10, 100)
But, when I want to use class operators like in this example:
local v1 = Vector2(1, 1)
local v2 = Vector2(2, 2)
local v3 = v1 + v2
I'm getting the following error: attempt to perform arithmetic on local
'p1' (a userdata value)
The C# variant of the class does have the + operator:
public static cVector2 operator +(cVector2 vector1, cVector2 vector2)
{
return new cVector2(vector1.X + vector2.X, vector1.Y + vector2.Y);
}
I know that you should make use of the Lua metatables and add a function
to "__mul" for the * operator for example. But doesn't LuaInterface does
that automatically? And if not, how could I automate this myself?

fisher exact test for testing ratios of two columns
fisher exact test for testing ratios of two columns
I am trying to see if the ratios of Non_syn_snps to Total_SNps is
significant or not for all 10 chromosomes. Here is the dataframe
Ch Non_Syn Total_Snps ratios
1 A01 4658 23657 0.1968973
2 A02 3347 16685 0.2005993
3 A03 7292 36963 0.1972784
4 A04 2608 13161 0.1981612
5 A05 1883 10665 0.1765588
6 A06 4141 22033 0.1879454
When i tried to do fisher test on the fourth column
fisher.test(data_total[,4])
I am getting this error "Error in fisher.test(test_fish[, 4]) : if 'x' is
not a matrix, 'y' must be given"
I even tried to convert this to matrix and do the same thing but still i
am getting the same error.
Can somebody tell me what i am doing wrong here? Also is it ok to just use
the fourth column for fisher test?
Thanks Upendra

Cannot add or update a child row: a foreign key constraint fails
Cannot add or update a child row: a foreign key constraint fails
I'm trying to use an SQL script to automatically add a schedule to and
from every airport. Here is the code I have so far:
INSERT INTO phpvms_schedules (depicao, arricao, distance)
SELECT
depart.icao,
arrive.icao,
ROUND(GreaterCircleNm(depart.lat,depart.lng,arrive.lat,arrive.lng),2)
as Nm
FROM phpvms_airports AS depart
INNER JOIN phpvms_airports AS arrive ON depart.icao <> arrive.icao
GreaterCircleNm function:
DROP FUNCTION IF EXISTS GreaterCircleNm;
DELIMITER go
CREATE FUNCTION GreaterCircleNm( lat1 FLOAT, lon1 FLOAT, lat2 FLOAT, lon2
FLOAT ) RETURNS float
BEGIN
DECLARE pi, q1, dist FLOAT;
SET pi = PI();
SET lat1 = lat1 * pi / 180;
SET lon1 = lon1 * pi / 180;
SET lat2 = lat2 * pi / 180;
SET lon2 = lon2 * pi / 180;
SET q1 = ACOS(sin(lat1)*sin(lat2)+COS(lat1)*COS(lat2)*COS(lon1-lon2));
SET dist = q1*180*60/pi;
RETURN dist;
END;
go
DELIMITER ;
All in all I really need help fixing this error:
