OpenSSH not connecting to IPv6 host unless 'AddressFamily inet6'
I have an OpenSSH client and server. Both are running on Debian 7 with
OpenSSH 6.0. I have a VPN established between the two machines, and the
VPN has functional IPv6. It does not have any IPv4.
The frustrating problem is that I can only connect to the server using
IPv6 if I have set the AddressFamily inet6 option in my ssh_config. I
really don't want to have to set this option. It sure seems like I should
be able to set AddressFamily any and have my connections work.
My Working connection over IPv6 looks like this.
working ssh_config
Host test-fw-01 test-fw-01.example.org
HostKeyAlias test-fw-01.example.org
HostName test-fw-01.example.org
AddressFamily inet6

I will have about 70 hosts using this IPv6 VPN. I want to simply put the
AddressFamily any in the Host * section of my ssh_config and then have my
connections get established. I don't want to have to explicitly list all
my IPv6 hosts in my SSH config. There will be no consistent naming pattern
so I can't do something like Host *.ipv6. I don't want to have to type the
-6 to connect via IPv6. Am I missing something obvious? What do I have to
do to get OpenSSH to connect use the IPv6 address since it is available?

How to crop borders/white spaces from image?
How to crop borders/white spaces from image?
I have a lot of images which have white borders around it. I would like to
crop those borders in one batch, preferably from command line. I believe
that it can be done with ImageMagick, but I couldn't find suitable
command.
I know that it can be done with Windows program named Irfanview with "Auto
crop borders" option, but I am looking for Ubuntu-based and preferably
command-line based solution.

yield and I didn't manage to get it right in two hours trying so many
different things. Could you please explain me why it does not work?

I'm looking for a way to have a button in my form that will add another
text input when clicked, similar to the attachments form in Yahoo Mail.
This way the user can have exactly as many input fields as they need.
Any ideas? Thanks, Luk
Here's my input field : (add.gif is the add.gif add icon for input field &
delete.gid which is remove the input field)
response.Write "<td align='left'><img src=""..\common_pic\add.gif""

Parse shortcode to array
Parse shortcode to array
i need to parse WordPress shortcode to array, in php, for example:
[parrent_shortcode attribute='1' attribute2='a']
[shortcode atrribute1=true attribute2=true]This is first

[shortcode atrribute1=false]This is second content[/shortcode]
[/parrent_shortcode]

)
[child2] => Array(

)
[content] => 'This is second content'

Also shortcodes can be without parrent wrapper and can be single
(selfclosing) without content. Also attribute can have spaces in it.
I try to accomplish it using explode but ther are so many combinations..

Modifying my SharePoint upper ribbon boarder color is not working well
Modifying my SharePoint upper ribbon boarder color is not working well
I have a Ribbon in side my SharePoint , which have different board color,
depending on the tab i am displaying, so i want to have the ribbon boarder
to always be blue. So using Firebug i have detected the classes which is
responsible for the ribbon as follow:-
I added the following code to my cusotm CSS:-
.ms-cui-tabBody{
border-color:#008CD2 #008CD2 #008CD2 #008CD2 !important;
border-top-color:#008CD2 !important;
}
.ms-cui-tabBody.ms-cui-tabBody-gr{
border-color:#008CD2 #008CD2 #008CD2 #008CD2 !important;
border-top-color:#008CD2 !important;
}
But unfortunately this has changed only the buttom boarder colour to be
blue, while the "Calendar" tab still have green upper boarder, and "Page
Option" tab have no upper boarder color ? can anyone advice on how I can
change the boarder to be all blue? Thanks.

C# regex building
C# regex building
I have an encode string in my C# web app:
<a href="/product.aspx?zpid=564">Item One </a>-10 -
10<br /><a href="/product.aspx?zpid=647">Item Two
</a>-1 - 1<br /> <br />
That is decoded to:
"<a href=\"/product.aspx?zpid=564\">American Arborvitae</a>-10 - 10<br
/><a href=\"/product.aspx?zpid=647\">Black Walnut </a>-1 - 1<br /> <br />"
Is there a relatively easy way to use a regex to get the values between
the </a>-10 - 10<br /> and </a>-1 - 1<br />? I am not really the best at
building regexes and I am not sure really how to define a pattern for
something like this. Or can the values be put into a string array easier?
The number of entries can vary between like 1-30.

That is decoded to:
"<a href=\"/product.aspx?zpid=564\">American Arborvitae</a>-10 - 10<br
/><a href=\"/product.aspx?zpid=647\">Black Walnut </a>-1 - 1<br /> <br />"
Is there a relatively easy way to use a regex to get the values between
the </a>-10 - 10<br /> and </a>-1 - 1<br />? I am not really the best at
building regexes and I am not sure really how to define a pattern for
something like this. Or can the values be put into a string array easier?
The number of entries can vary between like 1-30.
techgig july edition part 3
techgig july edition part 3
There is problem statement on techgig :
Davis is playing a very interesting mathematical game. He has collection
of sticks of length 1,2,3,....,N. He is making hexagon out of his
collection by using 6 sticks for each hexagon. He considers a hexagon
"good" if the biggest stick has length at least L and lengths of all the
other sticks are not more than X. A "good" hexagon does not have sticks of
the same length more than K times.
How many ways he can make a "Good" hexagon?
Input/Output Specifications Input Specification: Input contains four
integers-
N( 2 <= N <= 10^9)
L ( 2 <= L <= N and N-L<=100)
X( 1<=X< L )
K ( 1 <= K <= 5)
Output Specification: Output the number of different ways to make a "Good"
hexagon % 1000000007
Examples
Example:1 when N=8, L=7, X=5, K=3: { 1,2,2,5,5,7 } is a good hexagon but
{1,2,2,2,2,7}, { 1,2,3,4,5,6},{1,2,3,4,6,7} are not.Two hexagons are
considered different if their side length sets are different.
For example {1,2,3,4,5,6} , {1,1,1,2,2,3} and {1,1,2,2,2,3} are all
different hexagons. But {1,2,3,4,5,6} and { 2,4,6,1,3,5} are not
different.
Example:2 When N=10, L=8, X=6, K=2 Output: Total hexagons= 374
Note: Please return -1 for invalid cases.
I am trying to solve it by calculating different combinations and adding
it together, my approach(probably wrong) is as below :
def factorial(x):
if x<=1:
return 1
else:
return x*factorial(x-1)
def combination(n,r):
return (factorial(n)/(factorial(n-r)*factorial(r)))
def goodHexa(N,L,X,K):
a=combination(N-L+1,1)
c=0
if K>=1: #total no. of combination without repeating any number
b=combination(X,5)
print b
if K>=2:
b+=combination(X,3)*3 #one number occurs twice
print b
b+=combination(X,4)*4 #two number occurs twice
print b
if K>=3:
b+=combination(X,2)*2 #one number occurs 3 times and one 2 times
b+=combination(X,3)*3 #one number occurs 3 times
if K>=4:
b+=combination(X,2)*2 #one number occurs 4 times
if K>=5:
b+=X #one number occurs 5 times
return (a*b)

Configuring biplot in Matlab to distinguish in scatter
Configuring biplot in Matlab to distinguish in scatter
My original data is a 195x22 record set containing vocal measurements of
people having Parkinson's disease or not. In a vector, 195x1, I have a
status which is either 1/0.
Now, I have performed a PCA and I do a biplot, which turns out well. The
problem is that I can't tell which dots from my scatter plot origin of a
sick or a healthy person (I can't link it with status). I would like for
my scatter plot to have a red dot if healthy (status=0) and green if sick
(status=1).
How would I do that? My biplot code is:
biplot(coeff(:,1:2), ...
'Scores', score(:,1:2), ...
'VarLabels', Labels, ...
'markersize', 15 ...
);
xlabel('Bi-Plot: Standardized Data');
xlabel('PCA1');
ylabel('PCA2');

How to print a list without it showing brackets and "" in the output ?
Python 3.3.2
So say I have a list named myList and it looks something like this :
myList = ["a", "b", "c"]
How would you print it to the screen so it prints :
abc (yes, no space inbetween)
If I use print (myList) It prints the following:
['a', 'b', 'c']
Help would be much appreciated.

how to get the appropriate version of pip
how to get the appropriate version of pip
Problem
I can't seem to get my packages to install to the correct site-packages
directory.
Background
I wanted to upgrade to python 3.3 but I found that I still need python2.6
in order to use yum (it isn't configured for python3). And so I have both
on my system.
Separate pip and easy_install for each version???
The issue is that when I download a package, and run "python setup.py
install" I find that it is installed in python2.6. I have tried using pip
and easy_install but they do the same. I have read that a solution is to
have different versions of pip (pip_2.6 and pip_3.3). But I can't find a
way to download the separate versions. One work around is to give the "-d
PathToSitePackages" argument in pip but this is inelegant.
other programs not using the newer version
Another issue is that I find that when I use systems such as sphinx, they
use the old version of python. I can't seem to figure out how to get them
to use the newer version of python.

Multiple dropdowns with dependancy
Multiple dropdowns with dependancy
I want to display 4 dropdowns, the items in each dropdown, depends on
selected item in previous dropdown.
I want to implement everything in javascript, meaning the servlet should
access DB (everything is stored in one reference table, where a column
"represents" a dropwdown ) only once and fetch all the relevant data.
The maximum number of possible combinations is about 9k.
How can I achieve that?
I guess the main problem is the data structure that should be used for
this. Maybe use of nested Maps?

Copy C Struct with char pointer
Copy C Struct with char pointer
Firstly, I am really sorry if this has already been asked and resolved - I
have spent ages searching and trying to adapt code samples to give me what
I need... but sadly to no avail. Essentially I am just trying to copy the
contents of one struct to another (which is documented here elsewhere but
I cannot get it to work).
A scanner populates the following struct when it reads a barcode:
struct barcode
{
char *text;
int length;
int id;
int min;
int max;
};
This is instantiated as:
static struct barcode code = {0};
I instantiate another one of the same type:
struct barcode *barcodeHolder;
This is intended to store a copy of the scanned barcode. This is because
other codes will then be scanned that indicated other steps such as
barcodes to indicate numbers or stages (eg. end, start, etc). Once I want
to write the struct contents to disk I use the "copy" of the struct as
that is what I want.
However, the char *text property always equals 'c' and not the value of
the barcode.
I copy them as follows:
barcodeHolder = malloc(sizeof(code));
barcodeHolder->text = malloc(strlen(code->text) + 1);
strcpy(barcodeHolder->text, code->text);
barcodeHolder->id = code->id;
barcodeHolder->length = code->length;
barcodeHolder->max = code->max;
barcodeHolder->min = code->min;
This is what I have got from other posts on a similar topic.
However, I am clearly doing something stupidly wrong and would welcome any
help anyone might be able to offer so that my copy of the struct text
element does actually get the right value copied.
Thank you!

to write the struct contents to disk I use the "copy" of the struct as
that is what I want.
However, the char *text property always equals 'c' and not the value of
the barcode.
I copy them as follows:
barcodeHolder = malloc(sizeof(code));
barcodeHolder->text = malloc(strlen(code->text) + 1);
strcpy(barcodeHolder->text, code->text);
barcodeHolder->id = code->id;
barcodeHolder->length = code->length;
barcodeHolder->max = code->max;
barcodeHolder->min = code->min;
This is what I have got from other posts on a similar topic.
However, I am clearly doing something stupidly wrong and would welcome any
help anyone might be able to offer so that my copy of the struct text
element does actually get the right value copied.
Thank you!
A few questions about node.js
A few questions about node.js
Am I right in thinking that node.js is a "total" development platform, in
much the same way as asp.NET, PHP and even classic ASP are?
There seems to be a lot of excitement about node.js which makes me a
little nervious about it being yet another "flash in the pan" type
technology that will fade away?
If I was going to go about learning node.js have you got any tips how I
might start out, without frying my brian?

UIApplicationDidBecomeActiveNotification filter notifications
UIApplicationDidBecomeActiveNotification filter notifications
I registered my main view controller for listening to
UIApplicationDidBecomeActiveNotification because I want to display a
UIAlertView each time the user enters my app :
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(someMethod:)
name:UIApplicationDidBecomeActiveNotification
object:nil];
It's working like a charm, my only problem is if my app gets interrupted
(by an UIAletView, such as a calendar event, or a popup asking for picture
access confirmation), the notification gets called once the alert view's
dismissed.
Any idea on how to detect ONLY when my app comes back from background mode ?

How long does a GCal AuthSubHttpClient token last?
How long does a GCal AuthSubHttpClient token last?
I've integrated the Google Calendar API and am able to retrieve the token
returned when a use grants access to their calendar, then using this token
I call:
getAuthSubHttpClient($token);
I then store the resulting string in the database. I am then able to use
this string as the client variable to push events to the users calendar.
My question is, will this expire at some point and I'll no longer be able
to push events to the users calendar? If so how can I get permanent
access?

Using a workbook with VBA to open a saved workbook, modify that pre-existing workbook, save and close
Using a workbook with VBA to open a saved workbook, modify that
pre-existing workbook, save and close
I am fairly novice to VBA and am looking for some help. I would like to be
able to run a VBA command in an excel workbook that will call open a
saved, existing workbook, at a specified location (Desktop\ThisBook.xlsx).
After opening the ThisBook.xlsx, the command will take numerical values
from specified cells in the VBA workbok (A1), add them an existing cell in
ThisBook.xlsx (something like ThisBook.xlsx A1 = ThisBook.xlsx A1 +
ActiveDocument A1) and save them where the ThisBook.xlsx data was.
Finally, overwrite the previous save file for ThisBook.xlsx and overwrite
the new data.
Thanks in advance for any help or direction.

Throw Error, Exception and Runtime Exception in child class
Throw Error, Exception and Runtime Exception in child class
I'm trying to understand the difference why a child class cannot override
a method implementation in the parent class to catch an Exception but no
problem while catching a Error,
For example in the below scenario, when I remove "Exception" from the
throws clause, it compiles fine.
class Supertest {
public void amethod(int i, String s) {
}
}
public class test extends Supertest {
public void amethod(int i, String s) throws Error, Exception {
}
}

render_template unable to jsonify object
render_template unable to jsonify object
I'm not doing a lot of web development, so my knowledge in this field is
pretty basic. However I have to write a simple web application using
python an flask.
In this application I have a simple class that looks like this:
class Task(object):
def __init__(self, id, title):
super(Task, self).__init__()
self.id = id
self.title = title
It can be assumed that id is an integer and title is a (unicode) string.
In a view function I want to render a template passing a list of Task
objects, like this:
@app.route('/tasklist')
@login_required
def tasklist():
tasklist = [
Task(1, u"Task 1"),
Task(2, u"Task 2"),
Task(3, u"Task 3"),
Task(4, u"Task 4")
]
return render_template( "tasklist.html", tasklist=tasklist)
When the view function is called, I get the following error message:
TypeError: <models.Task object at 0x103861210> is not JSON serializable
When I look around on the interwebs I see many examples, where they pass
lists of objects to views using render_template. So I wonder what am I
missing? My object only uses basic datatypes. Do I have to overload a
specific function?
Calling render_template with a list of simple strings (instead of class
instances) works fine.
I know, this is a very basic question, but I didn't find a satisfying
answer for now.

Should I ignore schema.rb because extension differs on development/production OS?
Should I ignore schema.rb because extension differs on
development/production OS?
My database uses PostgreSQL. I develop on Mac and this line is needed:
# db/schema.rb on Mac environment
enable_extension "plpgsql"
However, the extension is not required on Linux.
In this case, should we just ignore schema.rb and generate that through
db:migrate for both dev and production environments?

Is there way to access a pdf through a java application
Is there way to access a pdf through a java application
I'm trying to build an application which would parse a pdf having question
papers. As the pdf is parsed and the question number (in the pdf that is
being parsed) changes, the application clicks a snapshot of the question
by checking the question no change. So my questions are:
Can the pdf text be extracted for comparison?
Can we take snapshots in a pdf?
Can the coordinates of a pdf be obtained ?
Can the snapshot be customised according to the coordinates?

In iCal, I share publicly the considered calendar.
I copy the address in a browser but I replace the webcal:// by http://
It downloads a .ics file
When I try to import that file into my Google calendar, it fails...
Where am I wrong ?

RewriteRule rewriting legacy slugs
RewriteRule rewriting legacy slugs
I'm working on updating a website, moving from Drupal to Wordpress MS. One
of the big challenges is taking all of our old URLs that have been indexed
by google, and making them a lot prettier and smaller.
The old structure looks something like this:
<domain>/CA/<location_name>-superflous-data-slapped-at-the-end
The catch is that often times <location_name> contains hyphen characters
as well that we want to strip.
The new structure should look like
<domain>/<hyphen-stripped-location-name> Where we've trimmed off the state
abbreviation, the superflouous data, and we've stripped out the hyphens
from our location name.
Just to be clear I'd like to catch forward from the old URLs, whenever
they're requested, to these new pretty URLs that already exist.
I have a beginner's understanding of rewrite rules and my regex isn't very
good either. I have no idea where to begin, any help is greatly
appreciated!

Considering the below algorithm,
Loop1 until(i<n^2)

I think this is Theta(n^2*log(n)). This is correct or is the Big Theta

PHP security what is really necessary
PHP security what is really necessary
I was searching a bit and I found a line like this, in PHP;
$mots =
mysql_real_escape_string(stripslashes(strip_tags(htmlspecialchars($_POST['mots']))));
I was wondering how much of this was really necessary to protect a $_POST
entry as good as possible.

PHP form submission and AJAX validation
PHP form submission and AJAX validation
Below is basic script to check a username availability.
How can I prevent the form from being submitted if a username is already
taken. Ideally i would like to have a JS alert box pop up.
I've tried to add this to the JS but didn't work:
document.getElementById('submit').disabled
Also I've tried to add onclick="return validate();" to the form itself,
but no luck either: the form still can still get submitted.
<form id="edit" action="edit.php" method="post">
<fieldset>
<label>Username</label> <input type="text" class="input" name="username"
id="username"/><span id="status"></span>
<button type="submit" id="submit" value="add">Save</button>
</fielset>
</form>
<script type="text/javascript">
$(document).ready(function() {
$("#username").change(function() {
var username = $("#username").val();
var msgbox = $("#status");
if (username.length >= 4) {
$("#status").html('<img src="images/gif/ajax-loading.gif">');
$.ajax({
type: "POST",
url: "ajax_check.php",
data: "username=" + username,
success: function(msg) {
if (msg == 'OK') {
msgbox.html('<img src="/images/yes.png">');
return true;
} else {
msgbox.html(msg);
return false;
}
}
});
} else {
$("#status").html('<img src="/images/no.png"><font
color="#cc0000">too
long!</font>');
return false;
}
return false;
});
});
edit.php and ajax_check.php only contains some SQL queries.
Also, some users have JavaScript disabled on their browser, how could I
get around this?

CSS @font-face working for one font but not another
CSS @font-face working for one font but not another
I have successfully used the font face declarations for two fonts and it
works for all browsers except IE8 and below. I am using the code from
http://www.fontspring.com/blog/further-hardening-of-the-bulletproof-syntax.
The strange thing is on IE8, one font is working and the other is not.
Here is the CSS:
@font-face {
font-family: 'FreestyleScriptRegular';
src: url('freescpt.eot'); /* IE9 Compat Modes */
src: url('freescpt.eot?#iefix') format('embedded-opentype'), /*
IE6-IE8 */
url('freescpt.woff') format('woff'), /* Modern Browsers */
url('freescpt.ttf') format('truetype'), /* Safari, Android, iOS */
url('freescpt.svg#FreestyleScriptRegular') format('svg'); /*
Legacy iOS */
}
@font-face {
font-family: 'GillSansMTCondensed';
src:url(Gill_Sans_MT_Condensed.eot);/* IE9 Compat Modes */
src: url('Gill_Sans_MT_Condensed.eot?#iefix')
format('embedded-opentype'),
url('Gill_Sans_MT_Condensed.woff') format('woff'),
url('Gill_Sans_MT_Condensed.ttf') format('truetype'),
url('Gill_Sans_MT_Condensed.svg#GillSansMTCondensed') format('svg');
}
The FreestyleScriptRegular is not rendering correctly but the
GillSansMTCondensed is. I have tried everything I can think of and every
hack I can think of. I even used regenerated the eot file for the font
concerned using a different application but it didn't make any difference.
Is there anything peculiar to IE8 that would prevent the second font from
working? Any ideas?
Thanks

Is transaction needed when insert single line in mysql with InnoDB engine?
Is transaction needed when insert single line in mysql with InnoDB engine?
I used to use
<?php
$sql = "insert into test (owner) values ('owen')";
$db->autocommit(false);
if (!$db->query($sql))
$db->rollback();
else
$db->commit();
$db->close();
?>
However, today I run two insert php files in a same tables, without any
action. It is simple like:
<?php
$sql = "insert into test (owner) values ('owen')"; //the other php is the
same but replacing 'owen' to 'huhu'
for ($i = 0; $i < 100 * 1000; $i++) {
$db->query($sql);
}
$db->close();
?>
I run two php files in two different consoles. Then I got 200,000 records
without any error. Does that mean using transaction manually is really not
needed. As there are no conflicts.

the same old values instead of new values from the database for the new
userid i enetered. the refresh button has the code "textbox.clear()" for
all textboxes on the form and "radiobtn.clear()" for radio buttons on the
form" please suggest how to solve this.

Thanks a lot for feedback!
I have a very basic form with two fields (a login form). The variables are
posted to a script (shown below), however I am unable to see any posted
vars. I have no idea what I am doing wrong, can somebody help me out?

How can I tell whether a numpy boolean array contains only a single block of `True`s?
How can I tell whether a numpy boolean array contains only a single block
of `True`s?
If I have a numpy array containing booleans, say the output of some math
comparison, what's the best way of determining whether that array contains
only a single contiguous block of Trues, e.g.
array([False, False, False, True, True, True, False, False, False],
dtype=bool)
i.e. where the sequence ...,True, False, ..., True... never occurs?
of `True`s?

Dynamic Gradient Background based on int value
Dynamic Gradient Background based on int value
for an order overview I have a list of multiple orders with different
priorities. They reach from -10 => very high priority to +20 => low
priority. Based on this priority I want to return a Gradient brush Color
dynamically.
For example:
From -10 to -0.5 it should it fade from darkred into orange
From -0.5 to +0.5 it should fade from orange into yellow into lime
From +0.5 to +10 it should fade from lime to green
I have never made this before and absolutly no clue how to solve this.
Even if you don't have a complete solution for me it would be very nice to
give me a hint.

Calling getLoaderManager().restartLoader(...) from onLoadFinished(...)
Calling getLoaderManager().restartLoader(...) from onLoadFinished(...)
This is my problem: I want to init/restart a second loader from
onLoadFinished(...) method after the first loader has finished his job
(load finished), since i need some values from first loaders cursor. So
the second loader depends on some values, which the first loader delivers.
It works... but if a configuration change appears (rotation), it crashes
because while in this call, since it can happen after an activity's state
is saved. So there is no activity attached. If you call getActivity() for
example it returns null. Same thing happens if you call
getLoaderManager().XXX of course.
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
getLoaderManager().initLoader(FIRST_LOADER, null, this);
(...)
}
...
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
switch (loader.getId()) {
case FIRST_LOADER:
data.moveToFirst();
value1 =
data.getString(data.getColumnIndex(DBHelper.COLUMN_FIRST));
value2 =
data.getString(data.getColumnIndex(DBHelper.COLUMN_SECOND));
getLoaderManager().restartLoader(SECOND_LOADER, null, this);
break;
case SECOND_LOADER:
(...)
}
}
But if I destroy loaders manually in onDestroy(...) method there are no
problems. Ok, it works that way, but it dont make me happy. So there must
be some other way to solve this.
(And Im sorry for my poor english :) i hope it is understandable :P)

recursively adding xml elements to a database
recursively adding xml elements to a database
I'm trying to create a multidimensional array from xml code, in the format
[element type, children], so that it creates a value and a reference to
child nodes, if there are any.
so if my xml looked like this:
<name>
<firstName>Mary</firstName>
</name>
my database array would look like this:
[name, firstName] and if you looked at firstName you would see: [Mary
(Youngest)]
So using my limited knowledge of recursive functions and DOM methods, I
came up with this code:
function buildDatabase(nodesAtLevel)
{
//ignore this code
alert(nodesAtLevel.length);
//if the element is a dead end
if (nodesAtLevel.length == 0 && nodesAtLevel[0].nextChild.length == 0)
//return the child node
{
youngestChild = new Array(nodesAtLevel.nodeName + "
(Youngest)", nodesAtLevel[0].firstChild.data);
return youngestChild;
}
//if this element has children
for (var i = 0; i < nodesAtLevel.length; i++)
{
//add the name of the element and its children to the array
var children = new Array(nodesAtLevel.nodeName,
nodesAtLevel[i].childNodes);
//return the array ,
buildDatabase(children);
}
}
And here's the function that tests it:
function test()
{
//load the document
var document = loadXMLDoc("testXML.xml");
elements = document.childNodes;
//give the database object to buildDatabase
database = buildDatabase(elements);
}
I keep getting "nodesAtLevel[i] is undefined"
So the problem statement seems to be this line:
var children = [nodesAtLevel.nodeName, nodesAtLevel[i].childNodes];
My logic is that if an element has multiple children, it will go through
each element of the array, and if that element is a reference to another
variable it will treat that as an array as well to continue down the tree.

Trying to make a web application send info to an executable on my machine using Java
Trying to make a web application send info to an executable on my machine
using Java
I have some java code that communicates with an executable that is on my
machine which codes certain orders based on four files and user input the
code for that is as follows:
void coder(File exe, File ord, File cod, File msg, File rls, String tcc )
throws ProcessException {
String[] cmd = {
exe.getPath(), // Executable
ord.getPath(), // InputOrder (IN)
cod.getPath(), // ResultsCodedOrder (OUT)
msg.getPath(), // Messages (OUT)
rls.getPath(), // Releases (IN)
tcc //User input
};
Process proc = null;
try {
proc = Runtime.getRuntime().exec(cmd); // Code the order.
} catch (IOException ioe) {
ioe.printStackTrace();
throw new ProcessException("IOException. Could not exec command.");
}
Within the same file I have coder actually putting in certain values for
the user input string and for the user made files here:
// This illustrates the (idealized) steps neccessary to code an order.
Order codeOrder(File taskdir, Order order) throws ProcessException {
String ordername = order.getName();
// Create temp 'input' files.
File orderFile = createTriconOrderFile(taskdir, order);
File releaseFile = createTriconReleaseFile(taskdir, order);
// Define temp 'output' files.
File messageFile = new File(taskdir, ordername + msgExt);
File codedFile = new File(taskdir, ordername + codExt);
// Code order.
coder(exe,
orderFile,
codedFile,

I would like to change this based on a user's preference and not have it
hard coded as 'valsel' and rather whatever the user decides...Any ideas on
how this may be implemented...
// Delete temp files.
// If there is an exception while coding the Task, these won't be
deleted.
// This is good because we can examine these files.
deleteTempFile(releaseFile);
deleteTempFile(codedFile );
deleteTempFile(messageFile);
deleteTempFile(orderFile );
return codedOrder;
}
using Java
I have some java code that communicates with an executable that is on my
machine which codes certain orders based on four files and user input the
code for that is as follows:
void coder(File exe, File ord, File cod, File msg, File rls, String tcc )
throws ProcessException {
String[] cmd = {
exe.getPath(), // Executable
ord.getPath(), // InputOrder (IN)
cod.getPath(), // ResultsCodedOrder (OUT)
msg.getPath(), // Messages (OUT)
rls.getPath(), // Releases (IN)
tcc //User input
};
Process proc = null;
try {
proc = Runtime.getRuntime().exec(cmd); // Code the order.
} catch (IOException ioe) {
ioe.printStackTrace();
throw new ProcessException("IOException. Could not exec command.");
}
Within the same file I have coder actually putting in certain values for
the user input string and for the user made files here:
// This illustrates the (idealized) steps neccessary to code an order.
Order codeOrder(File taskdir, Order order) throws ProcessException {
String ordername = order.getName();
// Create temp 'input' files.
File orderFile = createTriconOrderFile(taskdir, order);
File releaseFile = createTriconReleaseFile(taskdir, order);
// Define temp 'output' files.
File messageFile = new File(taskdir, ordername + msgExt);
File codedFile = new File(taskdir, ordername + codExt);
// Code order.
coder(exe,
orderFile,
codedFile,
messageFile,
releaseFile,
"valsel");

deleteTempFile(orderFile );
return codedOrder;

Django 1.7 migrations for User Profile
Django 1.7 migrations for User Profile
I'm fairly new to Django and I'm using the latest version 1.7 from git in
a virtual environment with python3.3.
I'm making a simple blog web app as a learning project and I'm running
into a migration issue using Django's new in-built migration tools.
When trying to run ./manage.py migrate blog I'm getting the following
error (trimmed):
"...first_blog/django-trunk/django/db/migrations/graph.py", line 40, in
add_dependency
raise KeyError("Dependency references nonexistent parent node %r" %
(parent,))
KeyError: "Dependency references nonexistent parent node ('auth',
'0001_initial')"
The model that is causing the error is this one, presumably because of the
relation to the User model
from django.contrib.auth.models import User
...
class Author(models.Model):
user = models.OneToOneField(User, related_name='profile')
def gravatar_url(self):
return "http://www.gravatar.com/avatar/%s?s=50" %
hashlib.md5(self.user.email).hexdigest()
User.profile = property(lambda u: Author.objects.get_or_create(user=u)[0])
I realise that this is still in development but I couldn't work out if it
was an issue with my code (more likely) or an issue with the new built-in
migration tools.
Database is SQLite and let me know if there is any other parts of my
(limited) code you need to see. This is also my first post on SO, so
hopefully I've formatted it all ok.
Thanks in advance for any help. (Just set up the project in github so you
can see the entire picture if desired:

Printing 'long' or 'short' form of a string
Printing 'long' or 'short' form of a string
Hey guys I'm writing a program that has an abstract class 'Order' that is
extended by three classes 'NonProfitOrder', 'RegularOrder', and
'OverseasOrder'. Each implement the abstract method printOrder in the
abstract class.
The method accepts a string with is either "Long" or "Short"
If "Long" would look like:
Non-Profit Order
Location: CA
Total Price: 200.0
If "Short" would look like:
Non-Profit Order-Location: CA, Total Price: 200.0
public class NonProfitOrder extends Order {
public NonProfitOrder(double price, String location) {
super(price, location);
}
public double calculateBill() {
return getPrice();
}
public String printOrder(String format){
String Long = "Non-Profit Order" + "\nLocation: " + getLocation() +
"\nTotal Price: " + getPrice();
return Long;
}
}
This is the code I have so far, which works fine to print "Long", my
question is how can I get it to print depending on which "Long" or "Short"
is called.
Is there a built in java method to do this? Or is there a certain way to
write this string?
Thanks for any and all help!

json encode returning only partial data
json encode returning only partial data
Here is what I have:
public function get_model_by_make($make = null){
$model_data = $this->vehicle_model->get_model($make);
echo json_encode($model_data);
}
public function get_model($make){
$this->db->select('models_id, models_name');
$this->db->where('makes_id', $make);
$models_data = $this->db->get('Models');
$rows = array();
$rows[0] = '-Select-';
foreach($models_data->result() as $value){
$rows[$value->models_id] = $value->models_name;
}
return $rows;
}
The problem I'm having is if I pass a 0 or 1 to the get_model_by_make()
function the json data that is returned without the array key.
Example:
$data = get_model_by_make(1)
echo $data;
Result:
["-Select-","CL","CSX","EL","Integra","Legend","MDX","NSX","RDX","RL","RSX",
"SLX","TL","TSX","Vigor"]
If the number passed is greater than 1 then its returned like this:
$data = get_model_by_make(2)
echo $data;
Result:
{"0":"-Select-","35":"Alliance","36":"Ambassador","37":"AMX","38":"Classic"}
Why is json_encode not returning the key/value pair for 0 or 1? If I
var_dump the data the key/value is there.

Play 2.1.3 application with Maven enhanced models not loading lazy objects
Play 2.1.3 application with Maven enhanced models not loading lazy objects
I have a Play application that is been refactored. The play models have
been refactored out to its own Maven project so they can be shared with
other projects, and the ant-run plugin is being used to enhance the model
classes.
The models work ok up to the point that it involves loading the lazy
references (I'm using field enhancement with public fields). The
references are simply not loaded and an empty object is beeing returned.
The example code is:
@Entity
class A extends Model {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
public int id;
@ManyToOne
public B b;
public static Finder<Integer,A> finder = new
Finder<Integer,A>(Integer.class, A.class);
}
@Entity
class B extends Model {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
public int id;
public String someField;
}
....
....
A a = A.finder.by(someId); // returns the correct object
B b = a.b; // Returns a not null but empty object
System.out.println(b.someField); // someField is alway null
When I try to use the referenced object the object is not null, but it
seems it hasn't been initialized with data from the DB.
Even the id field on the B is populated correctly, but the rest of the
fields are not.
Maven seems to be enhancing the objects correctly (ant-run) since I can
get the objects with queries, etc.
If I specify .fetch("b") on the Java side the object is returned
correctly, but it wasn't necessary before, and sometimes is not possible
to do so (in the Scala templates).
I've checked the DB and the related objects are there. Also the code was
working while it was inside the Play project, but a lot of code (not all)
has stopped doing so since I moved the models outside Play.
Are there any specific configs for application.conf to specify lazy
loading or am I missing something?

php variable gets null at the end of the script?
I have a problem that I really can't figure out. basically I'm working on
a blog and I have a variable from a cookie that returns a post id. the
problem is that at the end of the script, when I enter an if(isset)
statement, the variable seems to be null and I can't understand the reason
behind it. it won't add anything to the database and it won't redirect to
the post id. here's the script:

SSI File in a Sibling Directory on Linux, Apache
SSI File in a Sibling Directory on Linux, Apache
I have a Linux server with Apache, where I am utilizing .shtml page
extensions to call in Server Side Include (SSI) files.
I have used many hosting environments where I can use separate directories
that are sibling directories to where my page is. So, for instance, I can
have a PAGES folder and an INCLUDES folder, and therefore can pull in the
include content into the page, using a directive like this:
<!--#include file="../includes/header.html" -->
Unfortunately, this is not working for me on this particular Linux server
I am on.
Interestingly, if I put the include file IN or UNDER the pages directory,
it works. So these two examples work:
<!--#include file="footer.html" -->
<!--#include file="includes/header.html" -->
But it does't work if I try to use that same directory using "relative" dots.
So this works…
<!--#include file="includes/header.html" -->
...but accessing the same directory through dots doesn't...
<!--#include file="../pages/includes/header.html" -->
Similarly, changing
file=" "
to
virtual=" "
doesn't work either. Nor does an absolute path.
I have read where it says that file="" won't allow for the ../ or the
absolute path, therefore eliminating references to files that are further
up in the directory structure… but those explanations usually tell me to
just use the virtual command, and that doesn't work either. (Server
setting?)
And yet, I am reasonably sure I have done this on other Linux servers.
I have called the host, but they weren't able to help much.
Is there a certain way I configure an .htaccess file to make this work?
Any suggestions? Or, a confirmation that it simply won't work and that I
shouldn't keep trying to make it work?
Thanks!

Backbone.js - History is creating two entries
Backbone.js - History is creating two entries
I'm not sure how to express this in code, as I can't seem to locate the
problem, but my issue is that Backbone.history seems to be recording two
items when a user clicks on a list item in my app.
This is not consistent.
My app has a 4 item navigation at the bottom that links to 4 main sections
(the first one being home - routed to '/'). If I load up the app, go to
one of the other navigation pages, then click the 'Home' button again and
then click one of the navigation options I get a list of items to choose
from. If I then choose one two entries are added - Firstly, for some
reason, a reference to the home route with /# at the end and then the
route for the item I clicked.
The end result is that 'back' then inexplicably takes me to the home page.
If it helps, my router looks like this...
var siansplanRouter = Backbone.Router.extend({
initialize: function () {
var that = this;
this.routesHit = 0;
//keep count of number of routes handled by your application
Backbone.history.on('route', function() { that.routesHit++; },
this);
window.SiansPlanApp.render();
window.SiansPlanApp.router = this;
},
routes: {
'': 'showHome',
'home': 'showHome',
'hub': 'showHome',
'samples': 'showJqmSamples',
'mealplanner': 'showCurrentMealPlanner',
'mealplanner/:planId': 'showMealPlanner',
'recipes': 'showRecipeSearch',
'recipes/:recipeId': 'showRecipe',
'settings': 'showSettings',
'versioninfo': 'showVersionInfo',
'*other': 'showHome'
},
routesHit: 0,
back: function() {
if(this.routesHit > 1) {
window.history.back();
} else {
//otherwise go to the home page. Use replaceState if
available so
//the navigation doesn't create an extra history entry
this.navigate('/', { trigger: true, replace: true });
}
},
showHome: function () {
SiansPlanApp.renderHome();
},
showJqmSamples: function () {
SiansPlanApp.renderView(new SiansPlanApp.views.Hub.Samples());
},
showMealPlanner: function (planId) {

SiansPlanApp.views.Planner.MealPlanner({ id: planId }));
},
showCurrentMealPlanner: function () {
SiansPlanApp.renderView(new
SiansPlanApp.views.Planner.MealPlanner({ current: true }));
},
showRecipeSearch: function () {
SiansPlanApp.renderView(new SiansPlanApp.views.Recipes.Search());

I'm not sure how to express this in code, as I can't seem to locate the
problem, but my issue is that Backbone.history seems to be recording two
items when a user clicks on a list item in my app.
This is not consistent.
My app has a 4 item navigation at the bottom that links to 4 main sections
(the first one being home - routed to '/'). If I load up the app, go to
one of the other navigation pages, then click the 'Home' button again and
then click one of the navigation options I get a list of items to choose
from. If I then choose one two entries are added - Firstly, for some
reason, a reference to the home route with /# at the end and then the
route for the item I clicked.
The end result is that 'back' then inexplicably takes me to the home page.
If it helps, my router looks like this...
var siansplanRouter = Backbone.Router.extend({
initialize: function () {
var that = this;
this.routesHit = 0;
//keep count of number of routes handled by your application
Backbone.history.on('route', function() { that.routesHit++; },
this);
window.SiansPlanApp.render();
window.SiansPlanApp.router = this;
},
routes: {
'': 'showHome',
'home': 'showHome',
'hub': 'showHome',
'samples': 'showJqmSamples',
'mealplanner': 'showCurrentMealPlanner',
'mealplanner/:planId': 'showMealPlanner',
'recipes': 'showRecipeSearch',
'recipes/:recipeId': 'showRecipe',
'settings': 'showSettings',
'versioninfo': 'showVersionInfo',
'*other': 'showHome'
},
routesHit: 0,
back: function() {
if(this.routesHit > 1) {
window.history.back();
} else {
//otherwise go to the home page. Use replaceState if
available so
//the navigation doesn't create an extra history entry
this.navigate('/', { trigger: true, replace: true });
}
},
showHome: function () {
SiansPlanApp.renderHome();
},
showJqmSamples: function () {
SiansPlanApp.renderView(new SiansPlanApp.views.Hub.Samples());
},
showMealPlanner: function (planId) {
SiansPlanApp.renderView(new
SiansPlanApp.views.Planner.MealPlanner({ id: planId }));
},
showCurrentMealPlanner: function () {
SiansPlanApp.renderView(new
SiansPlanApp.views.Planner.MealPlanner({ current: true }));
},
showRecipeSearch: function () {
SiansPlanApp.renderView(new SiansPlanApp.views.Recipes.Search());
},
showRecipe: function (recipeId) {
SiansPlanApp.renderView(new
SiansPlanApp.views.Recipes.Recipe({ id: recipeId }));
},
showSettings: function () {
SiansPlanApp.renderView(new
SiansPlanApp.views.System.Settings());
},
showVersionInfo: function () {
SiansPlanApp.renderView(new
SiansPlanApp.views.About.VersionInfo.ListView());
}
});
I've got some basic elements in a kick off file too here...
define(['router', 'regions/r-app', 'jquery', 'domReady'],
function (SiansPlanRouter, AppRegion) {
var run = function () {
// Global click event handler to pass through links to navigate
$(document).on("click", "a:not([data-bypass])", function (e) {
var href = { prop: $(this).prop("href"), attr:
$(this).attr("href") };
var root = location.protocol + "//" + location.host +
SiansPlanApp.root;
if (href.prop && href.prop.slice(0, root.length) === root) {
e.preventDefault();
Backbone.history.navigate(href.attr, true);
}
});
$.ajaxPrefilter(function (options, originalOptions, jqXhr) {
//options.url = '/api' + options.url;
});
// Create the global namespace region object.
window.SiansPlanApp = new AppRegion();
// Adds the authorization header to all of the API requests.
$(document).ajaxSend(function (e, xhr, options) {
xhr.setRequestHeader("Authorization", 'SiansPlan ' +
SiansPlanApp.cookies.getSessionData());
});
// Load up session data if any is present yet - this can't
happen until the XHR headers are set up.
SiansPlanApp.session.loadSession();
// Instantiate the router.
window.SiansPlanApp.router = new SiansPlanRouter();
// Boot up the app:
Backbone.history.start();
};
return {
run: run
};
});
