Tinymce url needs to be versatile
I need relative path in links which don't have full url and i don't need
relative path in url which have full url.
When i insert in tinymce: 1. I need full url(non-relative path) in:
"http://dignepal.com/images/logo.png" 2. But i don't need full url
(relative path) in: "javascript:"
While initializing tinymce i am currently using relative_urls as false and
it is causing problem in number 2 problem as mentioned above. And main
problem is i need it in same page and in same textarea.

Can i chain hash table data in python
Can i chain hash table data in python
I have a hash table in python and I have a lot of data and some are the
same but I need to chain them.
I want to make a music database which if i search some numeric values
called HZ i could find the name of the song.
So lets say i hava a song Called Song 1 I measure it HZ values but their
are countless 10 to be specific.
What I want to make is to have the ability to search any HZ value and have
the same result.
Song 1
10 HZ
20 HZ
30 HZ
40 HZ
50 HZ
60 HZ
70 HZ
80 HZ
90 HZ
100 HZ
So if I input any of these 10 values i would get the name Song 1 as results

Stack traces vs. TCO: Do non-tail recursive languages generally have efficient stack frames?
Stack traces vs. TCO: Do non-tail recursive languages generally have
efficient stack frames?
One reason I have heard for some languages to not support tail-call
optimization (TCO) is that this optimization comes at the cost of
obfuscating the call stack if/when debugging should require one to look at
a stack trace. (I have heard other reasons such as "The virtual machine
does not support it", but let's disregard Java for now.)
It seems then that for some set of languages where TCO would be possible,
but one does not perform it, the only purpose of stack frames is to
maintain meta-data for any eventual stack trace to be generated. I.e., the
stack frame could be minimal, containing only enough information to
generate the stack trace.
Question(s): Would it not make sense to minimize the size of such stack
frames? Would it not minimize the use of stack space, thus allowing deeper
levels of recursion before running out of space? Is this attempted in
languages where this thought applies? (I'm thinking in particular of
Python.) Or is this a lost effort with regards to actual space saved? (I
imagine that the meta-data necessary for generating nice stack traces is
actually quite a lot compared to what's normally in a stack frame.)
Idea in short: Minimize size of stack frames as an alternative to TCO.
PS. My thoughts are not based on any actual benchmarks. I could be way off
here.

swapImage {src: ‘image2.jpg’} doesn't respond in Rails 3.1
swapImage {src: 'image2.jpg'} doesn't respond in Rails 3.1
I'm in the midst of upgrading my Rails app from 2.3 to 3.2, but I'm stuck
on 3.1 at the moment.
I'm currently struggling with converting references to image filenames
into a syntax that works with the asset pipeline. The main place I need
with help with this issue is with my button rollover swapImage statements.
Here's an example:
<%= image_submit_tag "signin.jpg", {:class => "swapImage { src:
'#{image_path('signinHover.jpg')}' }" %>
This works in development. But when I deploy this code to production, the
rollover still doesn't work. I get no apparent rollover response at all.
Also, the single quote still appears escaped when I view source:
<input class="swapImage {src: '/assets/signinHover.jpg'}"
src="/assets/signin.jpg" type="image" />
I'm guessing this might be part of my problem.
I'm also wondering if perhaps I'm not loading my javascript/jquery assets
correctly using the asset pipeline. But when I check
https://staging.genlighten.com/assets/application.js, I see the swapImage
code appearing just fine.
I'd appreciate advice on how to implement swapImage correctly in Rails
3.1, with the proper syntax for images served by the asset pipeline.
Alternatively, is there a better approach to rollover button images that I
should use instead?
Thanks very much,

Print flowdocument scroll viewer on multiple pages
Print flowdocument scroll viewer on multiple pages
I'm trying to print my FlowDocument (which is wrapped into a
FlowDocumentScrollViewer) because I have a lot of texts/Textbox/combobox
and the page height can become high !
I'm using this :
PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == true)
{
Scrollvvv.Document.ColumnWidth =
printDialog.PrintableAreaWidth;
Scrollvvv.Document.ColumnGap = 0;
printDialog.PrintDocument(((IDocumentPaginatorSource)Scrollvvv.Document).DocumentPaginator,
ServicesLangue.RM.GetString("TITRE_MODIFIER_SALON_EXPOSANT"));
}
My xaml looks like :
<FlowDocumentScrollViewer Name="Scrollvvv"
VerticalScrollBarVisibility="Auto">
<FlowDocument Name="flowDoc" PagePadding="10">
<Section>
<BlockUIContainer>
<Grid Name="grid_principale">
<!-- Lot of stuffs here -->
</Grid>
</BlockUIContainer>
</Section>
</FlowDocument>
</FlowDocumentScrollViewer>
The thing is : It prints all my data in 1 page, the width is ok (i might
add some margin but that's ok) but it compresses all my controls to fit in
one page in height.
How to fix this ? I'd just want to disable this auto Height and keep the
original size.
Thanks !

Creating arrays with size as a variable
Creating arrays with size as a variable
I am trying to create a new array in this way:
final boolean[] arr = new boolean[list.size()];
This line is throwing a null pointer in my code in some cases. Under what
situations can this happen? Can it happen when the list has zero elements?
I am sure the list is not null at this stage.

How do I use values from a tuple whic is in a list of tuples as arguments for a function?
How do I use values from a tuple whic is in a list of tuples as arguments
for a function?
I'm trying to construct a simple tilemap thingy, as part of a larger
project, and one of the solutions I came out with was to use a function
like so:
def tile((value, X, Y)):
if value == 1:
pygame.draw.rect(screen, (0, 0, 0) (X, Y, 64, 64), 0)
The idea being that I set the level out as a list of tuples that contain a
value which denotes the tile to be drawn there, and then the coordinates
of that tile.
This, of course, doesn't work since you can't use a tuple as an argument.
My solution to this was to instead get the values out of the tuple in the
list:
def tile(value, X, Y):
if value == 1:
pygame.draw.rect(screen, (0, 0, 0) (X, Y, 64, 64), 0)
level = [(1, 0, 0), (rest of list)]
tile(level[0[0]], level[0[1]], level[0[2]])
Which didn't work, and gave me
Traceback (most recent call last):
tile(level[0[0]], level[0[1]], level[0[2]])
TypeError: 'int' object has no attribute '__getitem__'
Does anyone have a workaround for this? Some way I can feed a tuple into a
function as a series of arguments? Or am I just using a completely
idiosyncratic method that won't ever work ever? I'm guessing this is just
due to my blinding incompetence, although I would like to be told
otherwise.

for a function?
I'm trying to construct a simple tilemap thingy, as part of a larger
project, and one of the solutions I came out with was to use a function
like so:
def tile((value, X, Y)):
if value == 1:
pygame.draw.rect(screen, (0, 0, 0) (X, Y, 64, 64), 0)
The idea being that I set the level out as a list of tuples that contain a
value which denotes the tile to be drawn there, and then the coordinates
of that tile.
This, of course, doesn't work since you can't use a tuple as an argument.
My solution to this was to instead get the values out of the tuple in the
list:
def tile(value, X, Y):
if value == 1:
pygame.draw.rect(screen, (0, 0, 0) (X, Y, 64, 64), 0)
level = [(1, 0, 0), (rest of list)]
tile(level[0[0]], level[0[1]], level[0[2]])
Which didn't work, and gave me
Traceback (most recent call last):
tile(level[0[0]], level[0[1]], level[0[2]])
TypeError: 'int' object has no attribute '__getitem__'

Convert two vectors of int with the same length into one vector of pairs of int in C++
Convert two vectors of int with the same length into one vector of pairs
of int in C++
In C++, if I have two vectors of int A = [1, 2, 3 ,4] and B = [1, 2, 3,
4], how can I merge them into one vector of pairs as [(1,1), (2,2), (3,3),
(4, 4)]? Of course I can do that with a loop. But can we do that using
suitable STL functions and iterators?
Thanks!

statnet network missing vertexes
statnet network missing vertexes
I am using network claas from statnet in R.
They have some tutorials in statistical software journal. So I founf
information about 'na' attribute for vertexes and edges. But I can not
find any information in manual or the Internet about this for vertexes (
it still some about edges ). This attribute is logical and if TRUE then
vertex is unobserved. And when I print network class vertexes and edges do
not have that attribute, but tutorial says that it is default attribute.
Does anybode know what happend to this attribute or it just me can not
find info.

Set CSS class from one page to another - WordPress, jQuery AJAX
Set CSS class from one page to another - WordPress, jQuery AJAX
In WP theme I have post.php (for single post item) and blog.php (for blog
layout). On single post, CSS classes are added to post div via jQuery (on
click).
How to get that classes (strings)from single post (post.php) and use them
in blog.php?
EG. Single post (post.php) print this html
<article class="single-post post-1">
<p>sometext</p>
<a>click</a>
</article>
<script>
jQuery("a").click(function(){
jQuery("article").addClass("singleClass");
});
</script>
Blog posts (blog.php)
<article class="blog-post post-1">
<p>sometext</p>
</article>
<article class="blog-post post-2">
<p>sometext</p>
</article>
And also to get class from single post 1 and add it to blog post 1, post 2
to post 2, etc. First time trying AJAX, so I'm not sure what to do. jQuery
in post.php
var postClass = voteText+'-'+voteNumber; //some variables declared earlier
jQuery.ajax({
type: "POST",
url: "ajax-class.php", //or /wp-admin/admin-ajax.php? This mean that
data is posted to this file?
data: { 'dataString': postClass },
cache: false,
success: function() {
alert("Classes: "+postClass); // alert goes fine
}
});
now I need to GET data from ajax-class.php?
<?php echo 'Classes: '. $_POST['postClass']; ?>
This is not working. If someone could just point me to right direction.
Documentation and stuff. Thanx

How to select only specific columns from a DataFrame with MultiIndex columns?
How to select only specific columns from a DataFrame with MultiIndex columns?
I have DataFrame with MultiIndex columns that looks like this:
# sample data
col = pd.MultiIndex.from_arrays([['one', 'one', 'one', 'two', 'two', 'two'],
['a', 'b', 'c', 'a', 'b', 'c']])
data = pd.DataFrame(np.random.randn(4, 6), columns=col)
data
What is the proper, simple way of selecting only specific columns (e.g.
['a', 'c'], not a range) from the second level?
Currently I am doing it like this:
import itertools
tuples = [i for i in itertools.product(['one', 'two'], ['a', 'c'])]
new_index = pd.MultiIndex.from_tuples(tuples)
print(new_index)
data.reindex_axis(new_index, axis=1)
It doesn't feel like a good solution, however, because I have to bust out
itertools, build another MultiIndex by hand and then reindex (and my
actual code is even messier, since the column lists aren't so simple to
fetch). I am pretty sure there has to be some ix or xs way of doing this,
but everything I tried resulted in errors.

Whitespace/margin around last item on navigation list
Whitespace/margin around last item on navigation list
Can anyone give me a pointer on a site I've inherited. I'm more of an SEO
guy than raw code and I'm not making any headway on this.
Have a look at http://www.edwardjackson.co.uk and you'll see whitespace
around the last item in the left hand navigation list "Home Condition
reports".
Can anyone give me a steer as to what's causing this & what to do about it?
What I think is the relevant part of css is:
.nav li ul li a {
display: block;
list-style-type: none;
height: 18px;
text-transform: uppercase;
color: #504c40;
margin-left: -80px;

background-image: none;
padding-top: 0px;
padding-bottom: 0px;

Python matplotlib pcolor some labels are missing if the plot is not square
I am trying to create a heatmap with pcolor using the example from Heatmap
in matplotlib with pcolor? but I run into trouble.
First the example from the accepted anwser doesnt work for me and I get
the following error message:
Traceback (most recent call last):

Creating the plot "my" way leads to a good result with one exception: the
labels / ticks on the y-axis stop after a while. It seems that the number
of labels on the y-axis has to be of the same size as the number of labels
on the x-axis.
Here is the part of my code responsible for the creation of the heatmap.
Note that data is a two dimensional array (data.shape yields (20, 13)).
AA = ['G', 'A', 'V', 'S', 'T', 'C', 'M', 'L', 'I', 'K', 'R', 'E', 'D',
'Q', 'N', 'F', 'Y', 'W', 'P', 'H']
def plot_heatmap(data):
x_min = ((data.shape[1]-1)/2)*-1 #if the shape is for example 13
(has to be odd) we set the x_min to -6
x_max = (data.shape[1]-1)/2 #and the x_max to +6
x_labels = range(x_min,x_max+1,1) #this way we create the x_labels
going from -6 over 0 to +6
fig = pl.figure(figsize=(24,18))
ax = fig.add_subplot(1,1,1)
plot = ax.pcolor(data, cmap=pl.cm.Blues, edgecolors='k')
# put the major ticks at the middle of each cell
ax.set_xticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_yticks(np.arange(data.shape[1])+0.5, minor=False)
ax.set_ybound(lower = 0, upper = data.shape[0])
ax.set_xbound(lower = 0, upper = data.shape[1])
# want a more natural, table-like display
ax.invert_yaxis()
#ax.xaxis.tick_top()
ax.set_xticklabels(x_labels, minor=False)
ax.set_yticklabels(AA, minor=False)
fig.colorbar(plot)
pl.show()
You can find the resulting figure at
http://picload.org/view/oaidpww/heatmap.png.html
If you could tell me the reason for this behaviour and the way to change
it, I would be very happy.

AA = ['G', 'A', 'V', 'S', 'T', 'C', 'M', 'L', 'I', 'K', 'R', 'E', 'D',
'Q', 'N', 'F', 'Y', 'W', 'P', 'H']
def plot_heatmap(data):
x_min = ((data.shape[1]-1)/2)*-1 #if the shape is for example 13
(has to be odd) we set the x_min to -6
x_max = (data.shape[1]-1)/2 #and the x_max to +6
x_labels = range(x_min,x_max+1,1) #this way we create the x_labels
going from -6 over 0 to +6
fig = pl.figure(figsize=(24,18))
ax = fig.add_subplot(1,1,1)
plot = ax.pcolor(data, cmap=pl.cm.Blues, edgecolors='k')
# put the major ticks at the middle of each cell
ax.set_xticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_yticks(np.arange(data.shape[1])+0.5, minor=False)
ax.set_ybound(lower = 0, upper = data.shape[0])
ax.set_xbound(lower = 0, upper = data.shape[1])
# want a more natural, table-like display
ax.invert_yaxis()
#ax.xaxis.tick_top()
ax.set_xticklabels(x_labels, minor=False)
ax.set_yticklabels(AA, minor=False)
fig.colorbar(plot)
pl.show()
You can find the resulting figure at
http://picload.org/view/oaidpww/heatmap.png.html
If you could tell me the reason for this behaviour and the way to change
it, I would be very happy.

Is there a way to add items from server under and keep ul ID as i want?
Is there a way to add items from server under and keep ul ID as i want?
First, note that im using C#.
Basically, i know i can add server controls under a ul tag which is
runat=server:
HTML:
<ul id="myID" runat="server"></ul>
C#:
myId.Controls.Add(...);
but the issue is that once i add these items, the ul item has now a new
generated id (such as: id=ctl00_cphMainContainer_ctl00_myID) which ruins
my javascript code and also my css.
I was wondering, is there a clean way i could add my li items and keep my
ul as it is?

Function With Multiple Values JavaScript+JSP+Servlet
Function With Multiple Values JavaScript+JSP+Servlet
I have a project in Java with JSP+JavaScript+Servlets, with a function in
JavaScript to find some record in my database. When this record is found,
my function returns some value, and when it's not, my function returns a
message. Now I need another function to return several fields from my
database, and I don't know who. I'm not very familiar with JavaScript and
JSP.
This is part from my JSP code:
<tr>
<td>
<input type='text' id="noeco" name="noeco" size=5 maxlength=5
onkeyup="find_noeco_s(noeco,exists);">
<span name="exists" id="exists" readonly="readonly" style="width:
200px" value="{exists}"></span></input>
</td>
</tr>
<tr>
<td>
<input type='text' id="matric" name="matric" readonly="readonly"
value="{matric}"></input>
</td>
</tr>
<tr>
<td>
<input type='text' id="marca" name="marca" readonly="readonly"
value="{marca}"></input>
</td>
</tr>
<tr>
<td>
<input type='text' id="submarca" name="submarca" readonly="readonly"
value="{submarca}"></input>
</td>
</tr>
This is my JavaScript function "find_noeco_s":
function find_noeco_s(noeco,exists){
objsal = exists;
if(window.XMLHttpRequest)
ajax = new XMLHttpRequest();
else
ajax = new ActiveXObject("Microsoft.XMLHTTP");
ajax.onreadystatechange = funcionCallback;
ajax.open("GET", "/processEco.jsp?noeco="+noeco.value, true);
ajax.send("");
}
And this is my JSP processEco:
String noeco = request.getParameter("noeco");
String exists="";
String matri= "";
try{
PreparedStatement ps = PV.prepareStatement("select * from vehicles
where econom=?");
ps.setString(1, noeco);
ResultSet rs = ps.executeQuery();
if(rs.next()){
exists= rs.getString("dstipveh");
}else{
exists= "DOES NOT EXISTS";
}
%>
<%=exists%>
<%
}finally{}
%>
This function returns just one value (exists), but I need to return
several values. I tried to do this:
try{
PreparedStatement ps = PV.prepareStatement("select * from vehicles
where econom=?");
ps.setString(1, noeco);
ResultSet rs = ps.executeQuery();
if(rs.next()){
exists= rs.getString("dstipveh");
matri = rs.getString("matr");
marca= rs.getString("marca");
}else{
exists= "DOES NOT EXISTS";
}
%>
<%=exists%>
<%=matri%>
<%=marca%>
<%
}finally{}
%>
But I get just one value (exists). Like I said, I'm not very familiar with

values in my JSP like I do with just one value?

best way to load data from a website/server to iPhone
best way to load data from a website/server to iPhone
I have an own website and I want to write an app that loads data
(strings/texts) from it to fill a tableview on the iPhone (like a
to-do-list). I want to change the content of my app (of the tableview) all
the time without doing an update in the App Store. When the app starts it
should grab the content from my website...
Should I use FTP for doing things like that or are there better ways to
load and manipulate data?

OpenX: Deactivated Banners to shown in Zone
I have created one Compaign (Ad1_Compaign), and i have put two banners to
that Compaign (Ad1_Compaign). And I have linked these 2 banners(Banner1
and Banner2) to one Zone under one Website.
After that, I am running the Invocation Code for that Zone, it displays
with good (both banners are displaying randomly).
I have two doubts.
Doubt I:
How many times once change the banner everytime page re-loading? How to
measure that?...
Then After I deactivated the Banner1 means, In Zone->Linked Banners shows
good with Inactive Banner.
But generating the Zone Code the Banner1 is also displayed... But it is
deactivated...
Doubt II:
How to block to show Deactivated Banner in Zone?
Anyone Please Help me...

[ Psychology ] Open Question : Why dont I feel love?
[ Psychology ] Open Question : Why dont I feel love?
I am in my late teens and have Aspergers Syndrome. I also have social
anxiety that makes going out by myself very challenging. I also am
extremely shy(but can put on a good act when really needed, even though it
drains the life out of me and inside im a mess). When I was 15 I became
very depressed and suicidal and even now I occasionly slip into depressive
episodes which last from a few days to a week. I have a therapist who
helps me with the depressive episodes and social anxiety. I have been
bullied almost my who life and have had friends turn their back on me and
snub me without an explanation. I have also had to deal with the fact that
I have no contact with my birth father, which was a very hard time. I have
also self harmed in the past. I'm really trying hard to turn my life
around, im pushing my shyness boundaries to try to help my social anxiety,
I keep a positive diary(I know, seems very sad), and im eating better. I
should also tell you at this point that I will NEVER go on medication. I
am completely against it and nothing will change that. However, I've known
for a while now that I dont feel love. I have no friends where I live(I
did, but as usual, they ended up being idiots) and am happy being by
myself. I spend almost the whole day in my room learning about various
things and listening to music and this is what makes me happiest. I do
have a few friends where I used to live(one in particular is the most
special) but I just cant be bothered to keep in touch. I dont even miss
them. I do try to put more effort in for my most special friend as she is
important to me and I often find myself smiling when I think of our past
times together but I dont miss her. I dont know why, I just feel empty. I
think I would be sad if I lost her though, but im not sure. As for my
family, I am shy of everyone, my mum the least. I feel judged by them and
even asking them how they are is scary. I hate family trips out, they feel
fake and I feel no warmth when someone says they love me. Everything feels
like so much effort when I have to act like I care. I have never even
loved my past boyfriends before, I would just date them because they liked
me or because I was attracted to them physically. I havent had a crush on
anyone for about 4 years. However, I do feel fondness and warmth for some
people yet this is extremely rare. I feel so bad about this whole thing,
it makes me feel so cruel and heartless(which shows there may be a glimmer
of hope). Why is this? Is it Aspergers? Or could it be my social anxiety?
Its hard to feel warmth for people when youre feeling shy. How can I feel
love again? Will it just return when I no longer have social anxiety and I
no longer get deppressive episodes?

JAVA fail to convert char to utf8
JAVA fail to convert char to utf8
From wiki:
Consider a text file containing the German word f¨¹r in the ISO-8859-1
encoding. This file is now opened with a text editor that assumes the
input is UTF-8. As the first byte (0x66) is within the range 0x00¨C0x7F,
UTF-8 correctly interprets it as an f. The second byte (0xFC) is not a
legal value for the start of any UTF-8 encoded character. A text editor
could therefore replace the byte with the replacement character symbol to
warn the user that something went wrong. The last byte (0x72) is also
within the code range 0x00¨C0x7F and can be decoded correctly. The whole
string now displays like this: f�r.
I have a chinese word h, in GB3212, it is 6f22. In UTF8, it is e6bca2.
But when I try to convert it to unicode, i got EFBFBD (the replacement
char).
String correctedstring = new String(bbuf, "GB2312");//bbuf
contains 6f22
Charset charset = Charset.forName("UTF8");
CharsetDecoder decoder = charset.newDecoder();
CharsetEncoder encoder = charset.newEncoder();
ByteBuffer bb = charset.encode(correctedstring);
cbuf = decoder.decode(bb);
String utf8s = cbuf.toString();
utf8s is EFBFBD, rather than e6bca2.
I have no problem for some other chinese char, but i have problem with h.
I cant figure out the reason. If anyone know why, please kindly tell me
why and how to solve it? thanks.

C# Some newbie questions about collections
C# Some newbie questions about collections
I want to create an Extension. An extension is a component or a module
with default members like a name or a list of views. Component and module
inherit from extension members and implement their specific members.
public class Extension() {
public Name;
public List<View> Views;
// ...
}
public class View {
// ...
}
public class Component : Extension() {
// ...
}
public class Module : Extension() {
// ...
}
I can create a list of extensions like that :
List<Extension> Extensions = new Extensions<Extensions>() {
new Component() { Name = "Component 1" },
new Component() { Name = "Component 2" },
new Module() { Name = "Module" }
}
Now I want to create a menu. A menu can contain a view from my previous
extension :
public class MenuItem {
public string Name;
public View View;
}
List<MenuItem> Menu = new List<MenuItem>() {
new MenuItem(Name = "Menu 1", View = Extensions[0].Views[0]),
new MenuItem(Name = "Menu 2", View = Extensions[2].Views[0])
}
3 questions :
Is this the correct way (I'm newbie on c#) ?,
Is this possible with object initializer to assign an child object without
using index like that : View = Extensions[0].Views[0]
In my code, I can add in a new menu a view from a component or a module.
Is this possible to restrict only for component view ? So in my exemple,
second item is impossible to add.
Thanks

Flip graph of point set
Flip graph of point set
Is the flip graph of every point set in $\mathbb R^3$ connected? If
not, is there a set with an isolated node?
Def: For a point set $S$, the flip graph of $S$ is a graph whose
nodes are the set of triangulations of $S$. Two nodes $T_1$ and $T_2$ of
the flip graph are connected by an arc if one diagonal of $T_1$ can
be flipped to obtain $T_2$.
Any idea would be appreciate.

case, letters, numbers, symbols password and enabled two-factor
authentication.
In /etc/ssh/sshd_config I turned off remote root login and turned of
password-based login.
I'm running sshd, Apache, SSL, and MySQL on standard ports (although MySQL
should only be accessed from within the same host).
I plan to run yum update -y as a daily cron job. (should I make it hourly?)
I ran this script to configure my firewall...
*filter
-A INPUT -i lo -j ACCEPT
-A INPUT -d 127.0.0.0/8 -j REJECT
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A OUTPUT -j ACCEPT
-A INPUT -p tcp --dport 80 -j ACCEPT
-A INPUT -p tcp --dport 443 -j ACCEPT

-A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: "
--log-level 7
-A INPUT -j REJECT
-A FORWARD -j REJECT
COMMIT
Are there any changes that anyone would recommend?
(I realize that any apps I deploy may have their own security issues such
as SQL injection or cross site scripting). For now, I'm just talking about
the bare setup so far.)
Ember view to display a PDF
Ember view to display a PDF
In one of my views I would like to display a PDF, which is accesible via
URL. This should be done without opening an extra tab in the browser, and
without downloading the PDF (to view it outside the browser). It should be
visible embedded within the Ember application.
What I have in mind is:
Use the URL to get the PDF and make it accessible to the ember application.
Use a special "PDF view" to display the PDF.
Is this possible? What options do I have to display an embedded PDF in an
Ember application?

How to write a tester for a program that writes one bit at a time?
How to write a tester for a program that writes one bit at a time?
I am trying to write a tester for the following program to see if it
functions correctly, however, I'm not sure if I implemented flush()
correctly and for some reason I don't get any output. Can someone suggest
code that will test this class to see if I implemented flush and writeBit
correctly?
#ifndef BITOUTPUTSTREAM_HPP
#define BITOUTPUTSTREAM_HPP
#include <iostream>
class BitOutputStream {
private:
char buf; // one byte buffer of bits
int nbits; // how many bits have been written to buf
std::ostream& out; // reference to the output stream to use
public:
/* Initialize a BitOutputStream that will
* use the given ostream for output.
* */
BitOutputStream(std::ostream& os) : out(os) {
buf = nbits = 0; // clear buffer and bit counter
}
/* Send the buffer to the output, and clear it */
void flush() {
out.put(buf);
flush(); // not sure if this is how I should flush the buffer?
buf = nbits = 0;
}
/* Write the least sig bit of arg into buffer */
int writeBit(int i) {
// If bit buffer is full, flush it.
if (nbits == 8)
flush();
// Write the least significant bit of i into
// the buffer at the current index.
// buf = buf << 1; this is another option I was considering
// buf |= 1 & i; but decided to go with the one below
int lb = i & 1; // extract the lowest bit
buf |= lb << nbits; // shift it nbits and put in in buf
// increment index
nbits++;
return nbits;
}
};

Override the User.IsInRole and [Authorize(Roles = "Admin")] for MVC4
application
I have created a custom role provider for my MVC4 application where I have
been successfully able to override CreateRole, GetAllRoles and RoleExists
methods and link them to my existing database as follows:
namespace Project.Providers
{
public class MyProvider : System.Web.Security.SqlRoleProvider
{
private MyContext dbcontext = new
MyContext(System.Configuration.ConfigurationManager.ConnectionStrings["MyContext"].ConnectionString);
private Repository<User> userRepository;
private Repository<Role> roleRepository;
public MyProvider()
{
this.userRepository = new Repository<MetaLearningUser>(dbcontext);
this.roleRepository = new Repository<Role>(dbcontext);
}
public override string[] GetAllRoles()
{
IEnumerable<Role> dbRoles = roleRepository.GetAll();
int dbRolesCount = roleRepository.GetAll().Count();
string[] roles = new string[dbRolesCount];
int i = 0;
foreach(var role in dbRoles)
{
roles[i] = role.Name;
i++;
}
return roles;
}
public override bool RoleExists(string roleName)
{
string[] roles = { "Admin", "User", "BobsBusiness" };
if(roles.Contains(roleName))
return true;
else
return false;
}
public override void CreateRole(string roleName)
{
Role newRole = new Role();
newRole.Name = roleName;
roleRepository.Add(newRole);
roleRepository.SaveChanges();
}
public override bool IsUserInRole(string userName, string roleName)
{
MetaLearningUser user = userRepository.Get(u => u.Username ==
userName).FirstOrDefault();
Role role = roleRepository.Get(r => r.Name ==
roleName).FirstOrDefault();
if (user.RoleID == role.RoleID)
return true;
else
return false;
}
}
}
I tried to override the AddUserToRole method but it doesnt seem to be
available only the:
AddUsersToRoles(string[] usernames, string[] roleNames) .
Will I need to create a similar custom class for the ability to be able to
override:
AddUserToRole(string username, string roleName).
Similarly I have been able to override the IsUserInRole(string userName,
string roleName) but have been unable to find a way to override the
User.IsInRole(string roleName)
What else must I do so that When I use:
[Authorize(Roles = "Admin")]
It will be based on the role provider that I have set up and not the asp

Write a program to read a string from the command-line arguments,count the
number of occurrence for each uppercase or lowercase letter contained in
it. (Hint: define two arrays of size 26 to save the number of uppercase
letter occurrence and lowercase letter occurrence in the string
respectively).
The above is my homework, I have done it so far as:
int[]loweroccurrence={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,
16,17,18,19,20,21,22,23,24,25,26};
int[]upperoccurrence={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,
16,17,18,19,20,21,22,23,24,25,26};
String a=args[0];
String lowercase="abcdefghijklmnopqrstuvwxyz";
String uppercase="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
int i=0,j=0,k=0;
for(j=0;j<26;j++){
for(i=0;i<a.length();i++){
if(a.charAt(i)==lowercase.charAt(j)){
System.out.print(loweroccurrence[i]);
}
Obviously, it is wrong, as the question asks to use two arrays to store
the occurrence number for both upper and lower letter, I have no idea how
to print out the result as a number by using arrays, please help, cheers

Windows Small Business - centralized backup solution for network workstations
Windows Small Business - centralized backup solution for network workstations
We have a Windows domain-based small business network, about 30
workstations and 1 server. In addition we have a NAS device.
I want to make the computer system more secure and stable. I need a
solution for backup workstations and server.
Features: - central storage for backup files (NAS or Server) - when user
starts his machine, before login, an incremental backup made from
specified files (or full machine, bare metal...) to the central storage -
if needed, we can restore the backed-up data to the client machine (even
to different hardware)
Do you know any solutions, sotfware for this?
Thanks in advance!
p.s.: sorry for my bad english (I hope you understand my question)

When the online users count reaches 600,some users can't connect to
socket,can't send messages.And some users disconnects from chat.
How can I resolve this problem ? What is your opinion of this problem ?
How to deploy a play framework application with MySQL database
How to deploy a play framework application with MySQL database
I have written a web application using Play Framework 2.1.0 in Java, with
an existing MySql database on my pc. Now I want to deploy the app and my
database on a server or a cloud platform like amazon ec2. But I get some
questions:
Cloud platform is easy to use, but I don't know which one should I choose.
Some cloud platform service doesn't support mysql database, like google
app engine. So I want to find one that can import mysql database easily
and can be set up easily.Can you guys give me some suggestions and some
tutorials about setting play framework on it?
I get a server without any OS on it now. But I don't know how to set it up
to run my play framework application. It seems that I have to install a
server application like apache or something else. Which one is better? And
can you give me some tutorials about how to set a play framework on an
linux system, like ubuntu?

Configure Home/End key to move to start/end of line in IntelliJ
I know ctrl+right/ctrl+left will do that, but I am used to pressing
Home/End and it's frustrating when it doesn't do it in IntelliJ. I use
KeyRemap4Macbook which works great for terminal and elsewhere with the
Home/End key setting, but the settings for some reason do not work in
IntelliJ.
I am on MAC OSX, IJ 12.1.4.

Clarification on how Elmah set the Logged in User Name
Clarification on how Elmah set the Logged in User Name
I was searching on how the logged in user name was set using ELmah.
The closer i came is the below link
Logging username with Elmah for WCF Webservices
Elmah take the user from Thread.CurrentPrincipal.Identity.Name and not
from HttpContext.Current.User
To get more clarity on this does the Thread takes Name from the windows
log on ?
Or will it log the name if i set HttpContext.Current.User ?
How does it work. How application architecture should be to make ELMAH
feasible to log UserName ?
Thanks

OOP Programming in MATLAB with stored values that also change (like an incrementer)
OOP Programming in MATLAB with stored values that also change (like an
incrementer)
I am relatively new to object-oriented programming in MATLAB, so maybe I
just don't understand the philosophy behind it, but I cannot seem to
figure this out. I want to have a set of object properties. One property
is statically created on object creation, and the other is an incrementing
value which stores information relevant to the object's use.
classdef MyClass
properties
max_inc; % Statically created cap on the incrementer
incr; % The incrementer
end
methods
% Constructor
function c = MyClass(set_max)
c.max_inc = set_max;
c.incr = 1;
end
% Function to do some stuff
function value = Next(c)
% Do some stuff
set(c, 'incr', c.incr + 1);
end
% Set function which is causing me trouble
function c = set.incr(c, value)
if(value <= c.max_inc)
c.incr = value;
else
c.incr = 1;
end
end
end
end
I was able to make a work-around which doesn't error out by getting rid of
the set function and implementing the Next(c) function as:
% Function to do some stuff
function value = Next(c)
% Do some stuff
curr_inc = c.incr;
if(curr_inc < c.max_inc)
c.incr = curr_inc + 1;
else
c.incr = 1;
end
end
While this runs, it does not actually seem to change the value of incr
when Next(c) is called (it always thinks incr is the starting value). I
don't want to make incr dependent because it does need to store its value
so I know how many times it has been incremented previously, and I cannot
make this a handle object because I need more than one to be active at the
same time (unless I am completely misunderstanding how handle objects
work). Is there not a way to do this? This seems like it should be a
really easy thing to do with an object.

JMenu and JMenuItem
JMenu and JMenuItem
So, I have the following code:
JMenu debug = new JMenu("Debug");
debug.add(new Debug());
And then the Debug class is:
public class Debug extends JMenuItem {
public final String TEST_DEBUG = "Test";
public Debug() {
add(TEST_DEBUG, this);
}
}
After running the application I get the following error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException:
adding container's parent to itself
I know what it means, but I have no idea how I can make this right without
placing the container parent to itself? How would I pass the String to the
JMenu?
Any help is appreciated.

C# initialization array

Can anybody explain me, why are there code like this in msdn?
// Create the array to store the CDs.
CD[] cdLibrary = new CD[20];
// Populate the CD library with CD objects.
for (int i=0; i<20; i++)
{ cdLibrary[i] = new CD(); }
I cannot understand why the initialization of objects in an array does not
execute in the operator new. And it need additional actions. What did it
make for?

Splitting Excel file but retaining lookup data and formulas
Splitting Excel file but retaining lookup data and formulas
I have a master expenses file that has a page for each employee
summarising their expenses. The employee sheets run off a hidden data
sheets.
I want to send each employee a copy of their expenses with the lookups etc
hidden but still in tact so that they can complete the coding etc using
lookup lists like project and expense codes from the data sheets.
What I envisage is a macro create to a set of individual employee files
with only their page but with the lookups and data in each remaining in
tact and hidden. I've been trying to create a macro to systematically work
through the file creating new files for each employee deleting each of the
other employee sheets but retaining the hidden data and related lookups -
with no success
Any help appreciated.

procedure(where date between dateFrom and DateTo). i must have char(10). i
want to write function in c# to check the string and if the it's length is
less than 10 convert it to 10. my format is yyyy/mm/dd. (yyyy has no
problem in my control) for example i want to convert 1391/1/1 to
1391/01/01 please help me how i can insert 0 and check the number after /.

while ($line = <FH>) {
if ($line =~ /Exit time/) {
($exittime, $exittimeval) = split(': ',$line);
$stat{$qbsid} = {
time => $exittimeval
};
}
I now need to create a timestamp based on localtime such that the script
does not compare the log file for the time after the timestamp
(localtime). I have the code to compare the time as follows
$date1 = "$hr1:$min1:$sec1, $moy1/$dt1/$yr1";
$date2 = "$hr2:$min2:$sec2, $moy2/$dt2/$yr2";
sub to_comparable {

}
if (to_comparable($date2) > to_comparable($date1)) {
print "right\n";
} else {
print "wrong \n";
}
Here $hr1,$min1,$sec1,$moy1,$dt1 and $yr1 are local time variables while
$hr2,$min2,$sec2, $moy2,$dt2 and $yr2 are values obtained from hash.
Preferably while running for the first time it should compare the whole
file and a timestamp is created. Afterwards, the above idea starts.

Changing backslashes to forward slashes changes file size
Changing backslashes to forward slashes changes file size
I have two small to medium sized files (2k) that are for all intents and
purposes identical. The second file is the result of the first file being
duplicated and replacing backslashes with forward slashes. The new file is
bigger by 80 bytes (or one byte per line).
I did this with a simple batch script,and at first I thought the script
might have unintentionally added some spaces or other artifacts. Or maybe
the fact that their extensions are different has something to do with it
(one has a tmp extension and the other has a lst extension).
From an editor, I replaced all forward slashes in the new file with
backslashes and saved it without changing the extension.
And, hey guess what? The files were the same size again.
Now, before this is written off as a random fluke, I also see the same
behavior exhibited in three other pairs of files (in other words six
files) created in the same manner as the first. They are all one byte
bigger per line in the file. The largest is about 12k bytes, and the
smallest is about 2k.
I wouldn't think it has anything to do with escaping because I am on a
Windows box using the Windows 7 cmd.exe shell.
Also one other thing. I tried the following:
echo \\\\\ >> a.txt
echo ///// >> b.txt
The files matched in size (7 bytes)
Does anyone have an explanation for this behavior?

Merge Outlook Profiles
Merge Outlook Profiles
I have created 2 Outlook profiles one for my Wife and one for me over 4
yrs ago on Outlook 2007. With time my wife now has her own PC and I have
now taken over her business. So the problem is that I have her business
e-mail accounts(5 accounts) on one profile and my personal and other
business accounts(4 accounts) on the other profile. I want to merge both
profiles, while keeping settings like the incoming and outgoing servers,
and port settings. I don't mind reentering passwords.
I look at the registry entry but don't know if I would be stuffing things
up by trying to merge the two profiles.
Thanks
Mark

Will this work? 3 Displays w/ GTX 560 Ti, 2 in DVI, 1 in HDMI
Will this work? 3 Displays w/ GTX 560 Ti, 2 in DVI, 1 in HDMI
I currently have a computer running a GTX 560 Ti with two monitors (one in
each of the DVI ports). Is it possible to add a third display (without any
extra hardware or peripherals) by plugging it into the mini HDMI port?
What if I plugged the third monitor into any of the onboard graphic ports,
what would happen?

Improve JQuery function for make it able to accept variables
Improve JQuery function for make it able to accept variables
This code is intended to be able to toggle between showing and hiding an
element depending on its ID. But in this form, only works with the ID's
that are already written in the code.
I would like to transform the code to make it possible to give it easily
the variables like in standard javascript functions. Something like
Function(id) {variable = id; actions;}
Like this, I would be able to employ this function always that I want to
hide or show an html element just calling the function and giving it a ID
as a attribute. Any idea on how to transform this code?
var x;
x=$(document);
x.ready(init);
function init(){
var x;
x=$("#check"); // Here is the ID of the control element
x.click(Qocult_most);
}
function Qocult_most(){ //Show and scrolls down till the page's end
var x;
x=$("#most"); //Here is the ID element to show
x.toggle(500);
$("html, body").animate({ scrollTop: $("#STH").offset().top },
1000);

Google Play Services Location throwing NullPointerException
Google Play Services Location throwing NullPointerException
I am trying to run a service that tracks a users location using the Google
Play Location Services. I've followed the [Android Developers Google Play]
(http://developer.android.com/google/play-services/setup.html)
instructions but currently have a crashing app.
I am using the android emulator AVD with a Google API target (17).
I have
1) Installed the Google Play Services SDK
2) Made a copy of the Google Play services library project, imported it
into my Eclipse workspace, and referenced it in my current app, using
these [instructions]
(http://developer.android.com/tools/projects/projects-eclipse.html#ReferencingLibraryProject)
I am not sure whether or not I have to add anything to the Manifest
Some background on my app structure: I have created a Location Services
class with all of the error handling, and am calling that class' methods
via a service. My app is currently crashing when I call the:
GooglePlayServicesUtil.isGooglePlayServicesAvailable(mContext);
command which is in the servicesConnected() which is the first instance I
call anything Google Play related. So basically, where I am at: I am
trying to call the method checking if Google Play services is available,
and the app is crashing on:

Edit in place for a SugarCRM Subpanel
Edit in place for a SugarCRM Subpanel
Below is an image of a SugarCRM module I am building (actually 3 of them.
Projects, Project Tasks, and Project Files)
This image is a DetailView of the Project module. The Project Tasks and
Project Files modules are SubPanels of this module.
I am new to SugarCRM, my first week so I am still learning everything I
can. I have already added a lot of features to this but something I would
like to do is on the Project Tasks SubPanel. I would like to make it where
you can easily change the status of each record without leaving the page.
So my ideal solution would add a button on each Project Tasks record which
will let you edit in place the Status of that task, so you could mark it
completed or open, or whatever right in place.
So I am asking if this is even possible to add such a functionality to a
Subpanel and if it is, perhaps some examples of how to do such
modifications to a subpanel.

When examining global error bounds for Euler method, can I rescale the domain limits?
When examining global error bounds for Euler method, can I rescale the
domain limits?
I'm looking at provable global error bounds of the Euler method for the
first time and I was surprised to find that the bound grows exponentially
in the amount of time (the domain size) propagated i.e.
$\delta_{err}\le A \;dt\; (e^{L (t_1-t_0)}-1)$
With $A$ a function of problem dependent bounds (e.g. the Lipschitz
constant, $L$). At first, I thought this was extremely bad due to the
exponential dependence on the domain size but then it occurred to me that
I could rescale the time units such that $(t_1-t_0)=1$ but this seems like
it might be problematic.
Going beyond Euler method to Runge-Kutta etc. methods doesn't help if the
error bound grows exponentially with the domain size. As ODE is a well
established field, and most references don't explicitly mention the
exponential growth with the domain size I think it must be unimportant but
I cannot see how (other than rescaling). Hence my question is:
Is there a way to be okay with this exponential dependence, either by
rescaling such that $t_1-t_0=1$ or by any other means?

Broadcast Receiver Constantly Restarting
Broadcast Receiver Constantly Restarting
I'm making a widget which I want to update every second (It's like a
countdown/timer widget), so I'm using a AlarmManager and a broadcast
reciever to achieve this without waking the phone and using up all the
battery, but I keep getting a constant stream of errors in LogCat when
running the widget:
08-18 18:40:43.368 390-1988/system_process I/ActivityManager: Process
com.dysign.livetubecountdown (pid 9784) has died.
08-18 18:40:44.282 390-414/system_process I/ActivityManager: Start
proc com.dysign.livetubecountdown for broadcast
com.dysign.livetubecountdown/.WidgetAlarmManager: pid=9809 uid=10144
gids={50144, 3003, 1028}
08-18 18:40:44.306 9809-9809/com.dysign.livetubecountdown E/Trace:
error opening trace file: No such file or directory (2)
As you can see, the process keeps on dying and then restarting, this
happens when the phone is both awake and asleep.
Here is how I am starting the AlarmManager (This is inside the widget
provider class):
@Override
public void onEnabled(Context context) {
super.onEnabled(context);
AlarmManager
am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, WidgetAlarmManager.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
am.setRepeating(AlarmManager.RTC, System.currentTimeMillis() + 1000,
1000 , pi);
}
And this is the Broadcast Receiver code:
@Override
public void onReceive(Context context, Intent intent) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget_main);
DateFormat format =
SimpleDateFormat.getTimeInstance(SimpleDateFormat.MEDIUM,
Locale.getDefault());
remoteViews.setTextViewText(R.id.widgetTextView, "TIME = " +
format.format(new Date()));
ComponentName thisWidget = new ComponentName(context, Widget.class);
AppWidgetManager manager = AppWidgetManager.getInstance(context);
manager.updateAppWidget(thisWidget, remoteViews);
}
Any help would be much appreciated, thank you, SO!
I'm making a widget which I want to update every second (It's like a
countdown/timer widget), so I'm using a AlarmManager and a broadcast
reciever to achieve this without waking the phone and using up all the
battery, but I keep getting a constant stream of errors in LogCat when
running the widget:
08-18 18:40:43.368 390-1988/system_process I/ActivityManager: Process
com.dysign.livetubecountdown (pid 9784) has died.
08-18 18:40:44.282 390-414/system_process I/ActivityManager: Start
proc com.dysign.livetubecountdown for broadcast
com.dysign.livetubecountdown/.WidgetAlarmManager: pid=9809 uid=10144
gids={50144, 3003, 1028}
08-18 18:40:44.306 9809-9809/com.dysign.livetubecountdown E/Trace:
error opening trace file: No such file or directory (2)
As you can see, the process keeps on dying and then restarting, this
happens when the phone is both awake and asleep.
Here is how I am starting the AlarmManager (This is inside the widget
provider class):
@Override
public void onEnabled(Context context) {
super.onEnabled(context);
AlarmManager
am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, WidgetAlarmManager.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
am.setRepeating(AlarmManager.RTC, System.currentTimeMillis() + 1000,
1000 , pi);
}
And this is the Broadcast Receiver code:
@Override
public void onReceive(Context context, Intent intent) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget_main);
DateFormat format =
SimpleDateFormat.getTimeInstance(SimpleDateFormat.MEDIUM,
Locale.getDefault());
remoteViews.setTextViewText(R.id.widgetTextView, "TIME = " +
format.format(new Date()));
ComponentName thisWidget = new ComponentName(context, Widget.class);
AppWidgetManager manager = AppWidgetManager.getInstance(context);
manager.updateAppWidget(thisWidget, remoteViews);
}
Any help would be much appreciated, thank you, SO!
Toggle text, on a checkbox input change
Toggle text, on a checkbox input change
I searched and tried a lot of codes & samples but I didn't get to my
point. I have 3 checkbox inputs and 3 labels after each, and a div
including a <p> tag. I want when I check each checkbox, the next label
text to be copied in the <p> tag, and when I uncheck it, remove the text
in <p> tag. I mean toggling the label text inside the <p> tag by changing
the inputs.
my HTML code :
<div class="chbxs">
<input type="checkbox" name="country" id="Iran" rel="Iran" />
<label for="Iran">Mashad,Tehran</label>
<input type="checkbox" name="country" id="England" rel="England" />
<label for="England">London,Manchester</label>
<input type="checkbox" name="country" id="USA" rel="USA" />
<label for="USA">California,NewYork</label>
</div>
<div class="countries">
<p></p>
</div>
my jquery code :
$('.chbxs input[type="checkbox"]').click(function() {
var chkdChkbox = $(this).next('label').text();
if ($(this).prop('checked') == true) {
$('.countries > p').append('<span>' + chkdChkbox + '</span>');
}
else {
$('.countries > p').children('span').remove();
}
});
The problem is that if I uncheck an input, all spans will be removed. How
can I fix this? Tank you so much. P.S: I also want to separate texts from
each other by a comma.

Confuse what is the difference between two cases?
Confuse what is the difference between two cases?
My question is related to this SO question.
My first question is as far as I can understand number of objects are 3,
s1, s3 and "abc" (I posted an answer to this question). If some one says
it is 4. How that happens there?
consider my following class.
public class ObjectCount {
static int i;
ObjectCount() {
System.out.println(++i);
}
public static void main(String args[]) {
ObjectCount obj1 = new ObjectCount(); //i=1
ObjectCount obj2 = new ObjectCount(); //i=2
ObjectCount obj3 = obj1; // obj3 is also an object refer same as obj1
}
}
How many objects are there? again I think it should be 2. So how above SO
post answer can be 4 objects?can some one help me to figure it out where I
get some point incorrect?
FYI : Now previous issue has fixed on that post. Incorrect answer has made
correct. It is 3 object there. No need to worry.
