how to (if possible) create a SSL certificate for only one website on my apache2 server?
how to (if possible) create a SSL certificate for only one website on my
apache2 server?
I saw some similar posts like this , but it didn't help me at my exact
problem. So I am using ubuntu 12.04 on a server with apache2 on it. There
are like 5 websites which are Virtualhosts and Namebased running on it
(using the same port). Now I need another page whiche REQUIRES a SSL
certificate. Is it possible to run just the one page under ssl or do I
automatically load everything in it when I configure SSL ?
I know that I have to put the SSL server under Port 443 like this :
<virtualhost *:443>
SSLEngine On
SSLCertificateFile /path/to/your/sslcert
DocumentRoot /path/your/webcontent
</virtualhost>
Does anyone know and want to explain me, how to setup ssl for just one page?

Magento - How to clean up attributes not in attribute set
Magento - How to clean up attributes not in attribute set
I am taking over a website from another developer, and have found the
setup of attributes to be a bit of a mess.
Specifically, products have attributes that aren't associated with the
relevant attribute sets.
If you take wine with an attribute set "Wines", one of whose attributes is
"Grape Variety".
But I also have "Beers" with a completely different attribute set, but
somehow one of my beers has a Grape Variety.
It's not assigned to the Beers attribute set, it doesn't show up in the
back end for this product, (so I can't edit it) but if I look in the
database it's there (in catalog_product_entity_* and
catalog_product_index_eav), furthermore when I do an export it's there
too, and if someone searches for "Merlot", they are coming up with this
beer. There are hundreds of products like this.
What is the best way of removing all attributes from products that are not
within their assigned attribute sets?
I could figure it out in SQL I'm sure, but that's not the best way of
doing things as I'd be afraid of missing something and screwing up the
products altogether.

Is there a limit to “else if” statements?
Is there a limit to "else if" statements?
I would like to ask there a limit on how many "else if" clause we can put?
I have been told that if we are having too many "else if", it will lead to
stack overflow eventually. For example:
if (1 > 1){}
else if (1 > 2){}
else if (1 > 3 ){}
//and so on
else{}
However, I can't find any evidence on this subject, and Googling doesn't
give me the answer that I want. The question below is has the same title,
but has nothing related to the subject that I wanted to ask. Thanks in
advanced.

Positioning of Search Bar
Positioning of Search Bar
I have inserted a search bar by using my websites code injection points
and now trying to re position it below my site tag line. Below in an
screenshot of what I am trying to accomplish.
My website is www.jobspark.ca
<script type="text/javascript"

Get the Value from a Slider when the slider is moved (in Limesurvey)
Get the Value from a Slider when the slider is moved (in Limesurvey)
i'm working with Limesurvey and Javascript for the first time. I want to
get the value of a slider everytime it is moved. I didn't know how to do
this properly. Until now it got something like:
$(document).ready(function() {
$( "#slider-handle-576875X1492X18245SQ001" ).click(function() {
alert($( ".ui-slider-handle ui-state-default ui-corner-all"
).slider( "value"));
});
});
And this works so far, that everytime i click the slider, i get a alert,
but it only gives me [objetc Object] and not the value.
I'm not sure how i can get the value, because if i look at the html code
of the slider, the value (at this moment 14) is stored anywhere, just in
percentage via style="left: 46.666666666666664%;">
I just post it here so you can have a look!

Codeigniter routes 404
Codeigniter routes 404
I have a website on a local wamp server (I have used a virtual host
setup). However when I try to link to another controller on the site, I
just get a 404 page (not codeigniters 404). I'm sure I'm missing something
simple, but what I'm not quite sure.
If in the url I put the website.co.uk/index.php/aboutus I get the page
(although it's not got any of my formatting there).
I'm trying to have links in the format: website.co.uk/aboutus
Here is my routes.php
$route['404_override'] = '';
$route['default_controller'] = 'home';
$route['(:any)'] = '$1';
Here is my controller that I'm trying to link to:
class Aboutus extends CI_Controller {
public function index()
{
// $this->load->library('parser');
// $this->load->view('header_view');
// $this->loadContent();
// $this->load->view('footer_view');
$this->load->helper(array('form', 'url'));
$data = array();
$data["title"] = "Our Story";
$data["page_content"] = "here is some page content";
$this->load->view('aboutus_view', $data);
}
}
I am using the follow href tag for the link
<a href="<?php echo site_url('aboutus'); ?> ">
In my config file I have
$config['base_url'] = '';
$config['index_page'] = '';
Has anyone got any ideas as to what I'm missing?
Thank you.

Certain Normal Subgroups of a Free Group
Certain Normal Subgroups of a Free Group
Let $F$ be a free group on some set $X$. For any $x \in F$ and $n \in
\mathbb{Z}$, we have that $\langle x^n \rangle \lhd F$. Why does this
hold?
For any word $w \in F$, we have $wx^n w^{-1} = (wxw^{-1})^n$ and hence it
seems to suffice to show that $wxw^{-1} = x^k$ for some $k \in
\mathbb{Z}$, but I am not sure why this should be the case.

Submit data in chat app - should I have a button?
I'm building a chat application on a website. I don't know anyone who uses
their mouse to send the chat messages, rather that just hitting
return/enter. 10 years ago you always had a button as a alternative to
using your enter key. Although, take a look at Google Chrome, they don't
have a button to hit after you have entered your url. A few years back
they had. Now it's just enter.
Would there be any consequences of not having a button?

After reboot why wont my server allow my script to copy files?
After reboot why wont my server allow my script to copy files?
I have a server running centos, which hadn't been restarted in 540 days.
We had to put a secure cert on it, and rebooted.
There was a php script that was running, and has been for years which
copied files selected by a web application from their source, threw them
into a zip file and forced downloads along with an informational PDF.
Since that reboot, we have tried running the script, and although the zip
file and the pdf are created, and the pdf is put into the zip, none of the
images selected gets copied from the origin to the folder or pdf.
I guessed a permissions issue, but there are no errors on the logs that
say otherwise. The user for the files are all marked apache/apache which
is the same as the folder.
So I guess I am asking, would have permissions have changed on reboot
somewhere, or could they get assigned somewhere on reboot?
Alternatively, is there something else I should be looking for? The images
are moved and copied using gzcompress in a php script.

difference between Java and C++ copy constructor
difference between Java and C++ copy constructor
How does Java support copy constructor and how is it different from C++? I
would like to understand the Java equivalent of the logic to execute rule
of three (copy constructor, destructor, assignment operator) from the
compiler side of the story.

Send formatted list of tuples as body of an email
Send formatted list of tuples as body of an email
Maybe this has been asked already, but I can't find it, and I need help. I
have a list of tuple pairs:
mylist = [('name1', 'name2'), ('name3', 'name4'), ('name5','name6')]
The list is generated from a MySQL database and can be of any length. It
is possible that some of the names are the same. It is not absolutely
necessary that the data type be a list of tuples. That's just what made
the most sense to me. It can be a list of lists, tuple of tuples, etc. A
dictionary doesn't make sense to me, because, as previously stated, any of
the names can be the same. This is in python using django, which can't be
changed.
Anyway, I want to send an email with the contents of Mylist as the body. I
want to format it, though, so that it looks in the body of the email like
this:
name1, name2
name3, name4
name5, name6
In other words, I want it to look like normal text you would see in an
email body. Initially, my thinking was that I had to use a function and
generate a variable for each line of output. There may be a way to get
this done without creating new variables for each newline, but I can't
figure it out. To be honest, I haven't figured it out at all. I've tried
for loops, while loops, recursive functions, etc. No luck.
This is for work, and I could really use some help. Thanks

Singleton Pattern Implementation in Java [duplicate]
Singleton Pattern Implementation in Java [duplicate]
This question already has an answer here:
What is an efficient way to implement a singleton pattern in Java? 20 answers
I was recently asked in an interview: How do you implement a Singleton
design pattern in Java?
I was a little confused because there are 2 options:
1) Just have a static data member. A static member, e.g.
private static Logger logger;
will ensure that only one logger is shared among all objects of a given
class.
2) Implement an instance-controller that restricts instances:
public class LoggerWrapper {
private static Logger instance = null;
private LoggerWrapper() { }
public static Logger getInstance() {
if (instance == null) {
instance = new Logger ();
}
return instance;
}
}
What is the difference between these 2 singleton approaches?

Open a websitelink inside an android app with dynamically generated links
Open a websitelink inside an android app with dynamically generated links
I'm reading in an XML-file and one of these attributes is the article url.
A link, that - when clicked - navigates the user to the web page with his
standard browser.
I realized making the link clickable with the Linkify-method
articleURL[i].setText("Article-URL: " + Html.fromHtml("<a href='" +
((Node) articleURList.item(0)).getNodeValue() + "'>" + ((Node)
articleURList.item(0)).getNodeValue() + "</a>"));
Linkify.addLinks(articleURL[i], Linkify.ALL);
When I now click the link it opens up the website in my browser. What I
want to achieve now, is to open the web page in the same app. I've tried
it like that
String article = ((Node) articleURList.item(0)).getNodeValue()
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(article));
startActivity(browserIntent);
But this starts the browser as soon as the part is reached. And since it's
in a for loop to gather all information from the XML file it will directly
open the first web page linked there.
What I want to achieve now is that the app opens the website in the app
itself when the user clicks on the linkified link.
The data I have from the XML file gets 25-50 data sets. And to display
them I run a for loop. Now I just want, that, when the user clicks on one
of the 25 links, that the app starts its own browser (without address bar)
and just opens the website. How can I achieve this?

Why can auto-suggest not access methods from Reference Classes in R
Why can auto-suggest not access methods from Reference Classes in R
Do I need to export Reference Classes methods somehow? Because methods
defined within reference classes seem not work with $ operator
auto-suggest, while functions that reside in lists do. This is pretty
annoying when reference classes contain many methods and their definitions
become longer. Am I missing some return(invisible()) or export?
What's the trick here?

find how many times user touched the light sensor in Android
find how many times user touched the light sensor in Android
I want to know how many times a user touched the sensor , in an interval
of time. For that I used.
event.sensor.getType() == Sensor.TYPE_LIGHT
Then I thought I need to check for light blocking event(black\dark) with
some value defined , and then we can identify. Is it the way to get the
needful.

Copy an Internal file to an External location in Libgdx
Copy an Internal file to an External location in Libgdx
I'm trying to use these lines of code to copy a master file
data/HighScores.txt to an external location so its readable. Only problem
is, the code I'm using isn't creating the file..
public static void fixFile() {
FileHandle old = Gdx.files.internal("data/HighScores.txt");
System.out.println(new
File(Gdx.files.external("HighScores.txt").path()).getAbsolutePath());
Gdx.files.external("HighScores.txt").delete();
old.copyTo(Gdx.files.external(""));
}
I don't get any errors or anything, the file just doesn't seem to copy over.
Also, when I try and refrence it using
Gdx.files.external("HighScores.txt") It breaks the program or the reader
reads null

I'm trying to figure this out, given the following code:
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <string.h>
char mynum='0';
int main(void)
{
int i;

{
strcpy(buffer, "CHILD"); /*in the child process*/
for (i=0; i<5; ++i) /*both processes do this*/
{
mynum=i + '0';
sleep(1); /*5 times each*/
write(1, buffer, sizeof(buffer));
write(1, &mynum, 1);

Notice that mynum is a global variable.
Child is incrementing the ASCII value of mynum
Parent is not
Child and Parent can take turns running
Why does child print CHILD0, CHILD1, CHILD2, etc whereas parent prints
PARENT0, PARENT0, PARENT0, etc? Remember mynum is a global variable.

Change Text Indent Style with Javascript
Change Text Indent Style with Javascript
So in Javascript (not jQuery)
I can set visibility style of a div with an ID of example to visible with
the following:
document.getElementById("example").style.visibility = 'visible';
Question is, how do I do the same with the text-indent property? The below
doesn't work.
document.getElementById("example").style.text-indent = 'none';

JMeter: Calling external classes and methods?
JMeter: Calling external classes and methods?
I have a Java test project that I would like to import in my JMeter test
so that I can call the existing methods in the test project. I did some
research, and came to know that I can create a jar of my Java project,
copy the jar into the JMETER_HOME/lib/ext folder, and then use the
BeanShell Processor to call the external methods.
I am trying to use the existing test project, and call its methods to
generate a JSON payload. I added a BeanShell PreProcessor, and did
something like:
import com.qa.base.services.user.User;
User user = User.generateSimpleUser();
user.setField("username", "testUsername");
user.setField("password", "testPassword");
vars.put("requestJsonPayload");
This does not seem to work, and I get an ERROR:
ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval
Sourced file: inline evaluation of: ``import
com.qa.base.services.user.User'' : Typed variable declaration : Method
Invocation User.generateSimpleUser()
Anybody know how I can achieve what I am trying to do? Any suggestions,
comments, links to tutorials, examples would be helpful. Thanks in
advance!

Python design pattern suggestions for type translation
Python design pattern suggestions for type translation
I am teaching myself Python OOP and developing a program to translate
database DDL between DBMS flavours (MSSQL Server, DB2, Oracle and more).
Basically the program takes a DDL file, source DBMS type and target DBMS
type as arguments, and generates target DDL as required. To implement the
behaviour to translate I can only think of a quite long and complex set of
nested if statementst, for example (pseudocode only):
if sourceDBMS is 'a'
if targetDBMS is 'b'
translateAtoB()
if targetDBMS is 'c'
translateAtoC()
if sourceDBMS is 'b'
if targetDBMS is 'a'
translateBtoA()
if targetDBMS is 'c'
translateBtoC()
if sourceDBMS is 'c'
if targetDBMS is 'a'
translateCtoA()
if targetDBMS is 'b'
translateCtob()
Can anyone suggest a pattern that would simplify this logic based on 2
choices of many option types for source & target?

Finding the first child of an XML Elem in Scala
Finding the first child of an XML Elem in Scala
So, I'm working on a project which can receive multiple types of XML
requests. The type of the request is determined by the first child of the
root tag. So you could get something like this:
<a>
<b>
foo
</b>
</a>
or:
<a>
<c>
foo
</c>
</a>
And perform a certain operation on foo, based on whether the first child
of <a> is <b> or <c>. I can't figure out any simple way to determine the
first child of . I suppose I could do repetitive matching, first checking
for a \ 'b' then a \ 'c', etc. But I need to handle a bunch of different
request types, so this would get unwieldy quick. Elem.child isn't helpful,
it just returns a one-element list: the Element itself.
How can I get the first child of an Element, without knowing beforehand
the name of the tag?

Extract information from raw email
Extract information from raw email
I need a way to extract to/from/subject from a massive email archive.
They're just the raw sources of each email but I'm finding that there is a
massive range in formatting making it hard to get the info I need. I'm
using regular expressions which is working but not in all cases.
Can anyone suggest a more bullet proof way to do this or a resource that
would show me all the different acceptable formatting of to/from/subject?

Storing Large Amounts of Dictionary-Like Data Within an Application in Java
Storing Large Amounts of Dictionary-Like Data Within an Application in Java
I fear I may not be truly understanding the utility of database software
like MySQL, so perhaps this is an easy question to answer.
I'm writing a program that stores and accesses a bestiary for use in the
program. It is a stand-alone application, meaning that it will not connect
to the internet or a database (which I am under the impression requires a
connection to a server). Currently, I have an enormous .txt file that it
parses via a simple pattern (Habitat is on every tenth line, starting with
the seventh; name is on every tenth line, starting with the first; etc.)
This is prone to parsing errors (problems with reading data that is
unrecognizable with the specified encoding, as a lot of the data is
copy/pasted by lazy data-entry-ists) and I just feel that parsing a giant
.txt file every time I want data is horribly inefficient. Plus, I've never
seen a deployed program that had a .txt laying around called "All of our
important data.txt".
Are databases the answer? Can they be used simply in basic applications
like this one? Writing a class for each animal seems silly. I've heard XML
can help, too - but I know virtually nothing about it except that its a
mark-up language.
In summary, I just don't know how to store large amounts of data within an
application. A good analogy would be: How would you store data for a
dictionary/encyclopedia application?

First of all, let me get my point for this:
This is an emergency alert system, it pulls from a website which we
manipulate in the back office, the program can be minimized but cannot be

how). As you can see, if the program as close the Emergency Alerts
wouldn't be seen/heard....that's an issue. I have to deploy this
application on over 200 computers so I want it simple, I don't want to
create a scheduled task, etc.. to keep it running. I simply want it to not
be easy to close.

GetProcAddress, so our DLL is not

How to replace session_register() for PHP 5.4+
How to replace session_register() for PHP 5.4+
out of the blue I was getting the following error when logging in to one
of my sites:
Call to undefined function session_register()
After some research I saw that session_register() is deprecated after PHP
5.4. I checked in my hosting control panel, and sure enough it says
current version I'm running is PHP 5.4.19. I assume they just forced an
upgrade which is why this problem seemed to occur out of the blue.
I looked through several Stack Overflow posts and reviewed links to PHP
documentation. From what I gather, session_register() is deprecated and
should be replaced with $_SESSION instead.
Problem is, both of those already appear in my code. Here is the code in
my index.php file:
53 <? if ($username) {
54 session_register("ADMIN");
55 $_SESSION['ADMIN'] = $username;
56 ?>
So I hoped just by removing line 54 (the deprecated piece) then it should
work, however that is not the case. It broke the code when I did that.
Based on other posts I read HERE and HERE they seem to be saying that the
code I see in line 55 above should by itself do the trick. So I'm a bit
confused why it didn't work. If anyone can tell me what code I should use
I would sincerely appreciate it. The developer of the script is not really
offering support.

Why and how respond to OpenDolphin 'ValueChanged' confirmation
Why and how respond to OpenDolphin 'ValueChanged' confirmation
I have simple grails server/groovyfx app, where openDolphin is used for
client/server communication.
Here is what happening: When CMD_LOG command is sended from client to
server, server updates one value of presentationModel and responds: Whats
up?. OpenDolphin does one more action, client send 'ValueChanged'
confirmation, server acepts it, and responds empty command, and client
receives it.
My question is, HOW can I implement custom respond to 'ValueChanged', for
example check corresponding value in DB, or if client is allowed to change
it. And WHY is respond sended, when I did not implement it? I dont feel
well about sending empty messages out of my control.
Little bit of code, on client side, this closure is called on button press:
def sendToServer = { message ->
clientDolphin.send(message, new OnFinishedHandlerAdapter() {
@Override
public void onFinished(List<ClientPresentationModel>
presentationModels) {
// after action on server, this wants to read changed
presentation model
}
}
});
}

PHP website directory structure
PHP website directory structure
I am developing a PHP website. But I am confused about the directory
structure. My home directory structure is like this:
-index.php
-header.php
-footer.php
-product.php
-Folder1/index.php
-Folder2/InnerFolder/index.php
I have included header and footer in every page. Now I want the same
header.php and footer.php to be called by all index.php pages. But it
shows the other pages missing which are included from header. (e.g. CSS )
For Folder1 : I achieved it by changing my navigation links in header with
"../" But How would I do this for Folder2/InnerFolder ?
In short what is the ideal( and perfect) way to organize the pages which
won't disturb the future addition of new internal folders and their
index.php pages.
Please reply for your best practises.
Thanks

Web application cache control
Web application cache control
Ok, I have a Glassfish 4 application server running under the ip say
50.50.50.25 and binded to i.e. app.myhost.com.
When I access to the main page via using the plain IP address 50.50.50.25
the network statistics are
12 requests ❘ 153 KB transferred ❘ 1.92 s (load:
2.32 s, DOMContentLoaded: 2.32 s)
If I open it via the address app.myhost.com the network statistics are
12 requests ❘ 417 KB transferred ❘ 3.53 s (load:
3.73 s, DOMContentLoaded: 3.68 s)
My chrome browser gets half of the requests from cache when the page is
accessed via ip address so it loads faster.
I am just confused how can I make my static content loaded from cache or
force it 304 not modified?

Django prefetch_related From Model With Multiple ManyToMany Relationships
Django prefetch_related From Model With Multiple ManyToMany Relationships
Say I have a few models in Django:
class Foo(models.Model):
bars = models.ManyToManyField(Bar)
bazs = models.ManyToManyField(Baz)
class Bar(models.Model):
quxs = models.ManyToManyField(Qux)
I can use prefetch_related to get all Bars belonging to Foo and all Quxs
belonging to Bar with:
Foo.objects.prefetch_related('bars__quxs')
But how can I use prefetch_related to get this information as well as all
the Bazs belonging to Foo? Would something like:
Foo.objects.prefetch_related('bars__quxs', 'bazs')
work?

Detecting iPhone color
Detecting iPhone color
Recently Apple shows the new iPhones 5s and 5c this devices have to many
colors, white, pink, yello, blue, green, space grey, gold and silver...
wow is to many, but my question is:
I will to create an App with the possibility to detecting the color of the
device to turn the UI in the specific color for that device.
Now I know your answer, NO is NOT possible, and give me a minus vote, but
I ask to please take a moment to ponder on iTunes with your device
connected if is iPhone or iPad, because when you connect your device,
iTunes is able to detect the color, and show on the device page the
exactly color Black/White or iPod colors.
Someone know the method on xcode objectiveC to do that?
Or is only an ability for iTunes?

Filestream/Streamwriter not assigning values correctly
Filestream/Streamwriter not assigning values correctly
I have no experience with Filestream of StreamWriter so I am not sure if
there is something obvious that I am missing or not understanding.
I have a method that is using attributes from its current class, and
writing them to lines within a file, but it just seems to write blank
values to the file.
public void FileWrite()
{
FileStream fs = new FileStream("test.txt", FileMode.Append,
FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
sw.WriteLine("Title = " + title);
sw.WriteLine("Name = " + fName);
sw.WriteLine("Last name = " + lName);
sw.WriteLine("Gender = " + gender);
sw.WriteLine("Medicare no = " + medicareNo);
sw.WriteLine("Height = " + height);
sw.WriteLine("Weight = " + weight);
sw.WriteLine("Age = " + age);
sw.WriteLine("Daily Recommended calories = " + cal);
sw.WriteLine("Ideal Weight = " + idealWeight);
sw.Flush();
sw.Close();
fs.Close();
Readfile();
}
Any help would be much appreciated as I have not worked with Filestream or
StreamWriter in the past.

Python program run fine on Windows but not Linux
Python program run fine on Windows but not Linux
Currently, I'm working as a social manager for my company. Part of the job
is to manage several Twitter account for each department of the company.
Months ago, the boss said, "whenever the company post a new status, all
the department have to retweet it". That easy, but it really depressed
since i have to login, then logout all the account just to click retweet
button. So, i have an idea to make a small tool which can handle the job
for me.
The tool come with 2 files, and use tweepy module to handle oAuth, check
for new tweet and post retweet.
The first is spy.py: it will watch the company twitter to see if a new
tweet posted for each 30 minute.
import time
import tweepy
def spyMode(new_id):
# Setup spy agent
spy_consumer_key = 'spy_consumer_key'
spy_consumer_secret = 'spy_consumer_secret'
spy_access_token = 'spy_access_token'
spy_access_token_secret = 'spy_access_token_secret'
spy_auth = tweepy.OAuthHandler(spy_consumer_key, spy_consumer_secret)
spy_auth_url = spy_auth.get_authorization_url()
spy_auth.set_access_token(spy_access_token, spy_access_token_secret)
# Sleeping
print 'Spy is preparing, please wait...!'
time.sleep(1800)
print 'Prepare done, start spying now...!'
# Spy for new tweet from target user
spy_api = tweepy.API(auth_handler=spy_auth)
for status in spy_api.user_timeline(id='CompanyTwitter', count=1):
new_id = status.id
return new_id
The second one, named retweet.py. It's job is idle when the spy is running
and retweet when new status posted.
import time
import tweepy
import random
from spy import spyMode
account_file = 'deparment.txt'
account_line = 0
last_id = 0
new_id = 0
class ExtractAccount(object):
#This part is just to extract token information
pass
if __name__ == '__main__':
while True:
spy_id = spyMode(new_id)
if spy_id != last_id:
print 'Okay, spy see a new tweet ' + str(spy_id) + ' has been
posted!'
for account_line in xrange(deparmentCount):
try:
# Setup user agent
le_consumer_key = 'le_consumer_key'
le_consumer_secret = 'le_consumer_secret'
le_access_token = ExtractAccount().access_token()
le_access_token_secret =
ExtractAccount().access_token_secret()
le_time = time.strftime('%X')
auth = tweepy.OAuthHandler(le_consumer_key,
le_consumer_secret)
auth_url = auth.get_authorization_url()
auth.set_access_token(le_access_token,
le_access_token_secret)
# Create retweet for latest status
api = tweepy.API(auth_handler=auth)
if api.retweet(spy_id):
print 'At ' + le_time + ' a new retweet has been
created!'
except Exception as e:
print e
pass
account_line += 1
# Reset the bot
last_id = spy_id
account_line = 0
print 'Okay, you are good now!\n'
else:
print 'Spy has been sent, but found nothing!\n'
This tool running fine on my Windows machine, but when i upload it to the
company server which use CentOs. The retweet.py could not authenticate as
it said:
[{u message': Could not authenticate you', code': 32}]
Does everyone face this before? I know there are difference between Python
for Windows and Linux but i can't solve this!

This tool running fine on my Windows machine, but when i upload it to the
company server which use CentOs. The retweet.py could not authenticate as
it said:

Does everyone face this before? I know there are difference between Python
for Windows and Linux but i can't solve this!
Java regex: how to get rid of redundant patterns from (X) (Y) (X and Y)
Java regex: how to get rid of redundant patterns from (X) (Y) (X and Y)
I am writing Java regex patterns and have run into a situation where I
expect X or X or both but no null.
So the following regex pattern works fine for this.
(X)|(Y)|(XY)
But the problem is that X and Y can be quite long and I have to write a
lot of this kind, which means a lot of redundancy and maintenance
headache.
(X)?(Y)? doesn't work because it can match null which I don't want.
Thanks for reading my posting and I will greatly appreciate your help.

Which data model appropriate?
Which data model appropriate?
I have a news reader project on IOS. I created my entities as:
NewsSource
NewsCategory
List item
News
I think that if I create NewsSource in SQLite I can't add a new source to
NewsSource entity without application update.
How can I add a new row to NewsSource without application update or
is that data model appropriate for my project ?
Thanks.

In Sublime Text 2 how can I pass the current file path to a command called by a key binding
In Sublime Text 2 how can I pass the current file path to a command called
by a key binding
I'm working with sublime text 2 build 2221, on Windows 8; python 2.7.
I want to pass the name of the file I'm currently working on in st2 to a
command by calling a key binding like this:
{ "keys": ["ctrl+shift+1"],"command": "my_command", "args":{"argument":"$1" }
where "$1" gets replaced with the name of the file in the current view,
i.e. the file I'm looking at when hitting the keys. How would I go about
this?
I found the following references here and here which seem to talk about
this but I couldn't get it to work.
Relevant quotes from the links:
Link 1:
...
"args": {
"contents": "console.log('=== HEARTBEAT $TM_FILENAME
[$TM_LINE_NUMBER] ===');${0}"
...
--------------------------------------------------------------------------------------------
Link 2:
$TM_FILENAME Filename of the file being edited including extension.

Print Natural Sequence with help of 2 threads(1 is printing even and 2'nd
is printing odd)
I have tired this question, and i ended up with some doubts. Please help
me out
Doubt : If any thread is in wait state , and no other thread is notifying
that one , so will it never come to and end ? Even after using wait(long
milliseconds).
For Code : What my requirement is from the code(Please Refer My Code) :
a : Should print "Even Thread Finish " and "Odd Thread Finish" (Order is
not imp , but must print both)
b: Also in main function should print " Exit Main Thread"
What is actually happening : After lot of runs , in some cases , it prints
"Even Thread Finish" then hangs here or vice-versa. In some cases it
prints both.
Also it never prints "Exit Main Thread".
So How to modify code , so it must print all 3 statement .(Of Course "Exit
Main.. " in last , as i am using join for main.)
In brief : Main start-> t1 start -> t2 start ,, then i need t2/t1 finish
-> main finish.

django loop threw objects and change there values
django loop threw objects and change there values
I have my model set up so that when a liquor is added to a store, it gives
it it's own in-store ID based on the count. I've called this the SPI. The
addition function works fine, it properly assigns the correct SPI. But I'm
having trouble with the delete function. When an object is deleted from
the table, I need it to loop through the remaining objects and set there
SPI to one less. However I keep getting an error StoreLiquor matching
query does not exist. Lookup parameters were {'StoreLiquorID': 7,
'storeID': <Store: test store>} Am I not doing the query correctly?
The models:
class Store(models.Model):
StoreID = models.AutoField(primary_key=True)
user = models.ManyToManyField(User)
StoreName = models.CharField('Store Name', max_length=30)
(other things here too but probably not necessary for this case)
class StoreLiquor(models.Model):
StoreLiquorID = models.AutoField(primary_key=True)
liquorID = models.ForeignKey(Liquor)
storeID = models.ForeignKey(Store)
StorePrice = models.DecimalField('Store Price', max_digits=5,
decimal_places=2)
SPI = models.PositiveIntegerField('SPI', max_length=10)
The view:
def delete(request, liquor_id, store_id):
storeID = Store.objects.get(StoreID=store_id)
StLiquor = StoreLiquor.objects.get(storeID=store_id,
StoreLiquorID=liquor_id)
LiqSPI = StLiquor.SPI
SPIcount = StoreLiquor.objects.filter(storeID=store_id).count()
for newSPI in range(LiqSPI, SPIcount):
newStLiquor = StoreLiquor.objects.get(storeID=storeID,
StoreLiquorID=newSPI)
newStLiquor.SPI = newSPI-1

I have the following code and I am trying to deobfuscate it to readable
javascript. I tried jsbeautifier but it doesn't work. I found a lot of
links to various deobfuscators, but either they don't work or they are
only for Linux. So how do I deobfuscate this code so it is readable
javascript?

Is there an international movie showtimes API or data source?
Is there an international movie showtimes API or data source?
I am currently working on a mobile application and would like to feature
showtimes from many different countries. We are currently using the TMS
API (http://developer.tmsapi.com/docs/data_v1/) for the U.S. and Canada,
but would also like to feature a wider range of countries.
I know this can easily be done with HTML scraping, but since this is a
commercial project, I don't think that will be the best decision.
Any help guys? Thanks in advance!

SQL Query to Find Matching Records but Excluding those that Match Second Criteria
SQL Query to Find Matching Records but Excluding those that Match Second
Criteria
I have a SQL database and I want to locate all the records that match one
criteria, but exclude from that set of results the records that match a
second criteria. More specifically -
Table 'Documents' with Fields = 'DocID', 'Description', 'SignID'
Table 'Signatures' with Fields = 'SignID', 'SignatoryName'
I want to find all the Documents that have been signed by a specific
Signatory e.g.
SELECT d.DocID, s.SignID
FROM Documents AS d
INNER JOIN Signatures AS s ON d.SignID = s.SignID
WHERE s.SignatoryName = 'Search Name Here';
However, many documents are signed by more than one person (i.e. Documents
> Signatures is One-to-Many). I want to exclude those documents which have
been signed by anyone else, other than the specific Signatory in the above
query. Or put another way, I want to find all those Documents that have
ONLY been signed by the specific Signatory.
But I'm not sure how to revise my query to achieve this objective.

What HyperLink has been clicked in c# asp.net?
What HyperLink has been clicked in c# asp.net?
I am making an asp.net web application which has to play videos. In my
start page I have a hyperlink for each video. All the hyperlinks are
identical, except their names. This Means they all link to the same page.
Im interrested in knowing wether there is an option to know which
hyperlink was clicked. I would like to retrieve the name of the hyperlink.
My code for generating the hyperlinks looks as follows:
foreach (FileInfo i in corFiles)
{
HyperLink t = new HyperLink();
t.Text = i.Name;
t.NavigateUrl = "page.aspx";
CorrectArray.Add(t);
}
return CorrectArray;
The text of the hyperlink is Unique to a video, which Means I can change
the src destination of the video to play based on the text name. So the
question goes as follows. Are there any way of retrieving the text name of
the hyperlink when it is clicked by the user?
I hope you can help! Thanks in advance.

Combine and sort 2 tables
Combine and sort 2 tables
I have 2 DataTables (in a DataSet)
Table 1:

1 | id123 | 3
Table 2:
ID|ident |default|Pos

Now i want to do a sort with LINQ that produces the following output:
Result
ident|Pos
-------------
id425|0
id180|1
id1 |2
id123|3
Now im struggeling around with LINQ to achieve this with one linq query. I
am new to LINQ so i hope somone has a hint for me. My problem is how to
sort the two tables and combine the result. My code so far is :
var query =
from t1 in dataSet.Tables[tableOne].AsEnumerable()
from t2 in dataSet.Tables[tableTwo].AsEnumerable()
orderby t1[Pos]
orderby t2[Pos]
select new {t1,t2};
but that doesn't work.

bring all categories of data using where
bring all categories of data using where
I have two related tables, data(no, name, citycode, age) and city(code, city)
Table city
+------+------------+
| code | city |
+------+------------+
| A1 | Jakarta |
| A2 | Bali |
| A3 | Semarang |
| A4 | Surabaya |
| C1 | Dili |
| C2 | Jayapura |

I want to count the number of employees who are age 27 by city
my query :
select city.city , count(data.name) as Nmb_of_employees
from city
left join
data on data.citycode = city.code
where data.age = 27
group by city.city;
The result
+----------+------------------+
| city | Nmb_of_employees |
+----------+------------------+
| Bandung | 1 |
| Dili | 1 |
| Semarang | 1 |
+----------+------------------+
but the result I want is like this
+------------+------------------+
| city | Nmb_of_employees |
+------------+------------------+
| Jakarta | 0 |

How to add events on Jquery UI button
How to add events on Jquery UI button
I have a question on how to use Jquery UI.
This is my first time that I try Jquery UI and I could add a button by
using Jquery UI button.
Now, I'd like to add events when the radio is switched on and off.
How could I add events to Jquery UI button?
Thanks in advance !!
output
javascript
$(function(){
$('input[type=radio]').button();
$('.set').buttonset();
})
html
<div class="set">
<input type="radio" name="radio" id="radio1"><label for="radio1"
/>ON</label>
<input type="radio" name="radio" id="radio2"><label for="radio2"
/>OFF</label>
</div>
