Can you make Golang drop packets on writes rather than block?
Can you make Golang drop packets on writes rather than block?
Given a channel of length N, I want to write to it only if it is not full.
Else I will drop this packet and process the next one.
Is this possible in GOlang

Installing project's dependencies globally and running the project without `node=?iso-8859-1?Q?=5Fmodules/`_=97_how=3F?=
Installing project's dependencies globally and running the project without
`node_modules/` — how?
I decided to try learning DerbyJS and this is my first acquaintance with
NodeJS either.
I create a new Node/Derby project with derby new foo. This also creates a
node_modules/ folder which contains a copy of all packages the project
depends on.
The node_modules/ subdir of a blank Derby project is 144 MB large and
contains 12967 files (sic!). As a person familiar with Ruby's RubyGems,
RVM and Bundler, i find this insane. I can't express how wrong it is
(actually i've got some solid argumentation against that craziness but
StackOverflow is not a place for debate).
I thought that npm's -g flag would help me. I could install all packages
globally, i told myself. So i did:
derby new -n foo
cd foo
sudo npm install -g
Now my project weighs 152 KB and contains 24 files. Now that's reasonable.
But i fail to run it. When i do npm start, i get "Cannot find module
'express'":
lolmaus@sandy:~/hello_derby2$ npm start
> hello_derby2@0.0.0 start /home/lolmaus/hello_derby2

linux redhat 6 and installing easy_install
linux redhat 6 and installing easy_install
I'm completely new at this and needed a bit of help.
I've got a hosted server running Linux Redhat 6 and using Python 2.7
(which has just been set as the default from Python 2.6) located at
/usr/local/bin/python2.7
I'm trying to setup easy_install on the server, but I'm not sure if i'm
doing it correctly, on the bash screen i'm running: sudo apt-get install
python-setuptools
But it keeps asking for a sudo password, which i'm assuming is my normal
admin password that i've used to login via SSH? I've used my admin
password and my root password which both don't seem to work, can any one
help? Maybe it's an over sight from my side (being a newbie). Thanks

DesignTime Data
DesignTime Data
I have an ItemsControl that is bound at runtime to data fetched from the
web. but I'd like to be able to preview its item template in the visual
designer. I'm able to do this in WPF, but not in windows phone.
I've tried to check for DesignerProperties.IsInDesignTool in the
constructor of the page and if true add the items manually to the items
control, but it doesn't work.
I considered having a static resource with a list of items and binding to
it, but there's no <x:Array> in windows phone also.
I also tried setting ItemsSource="{d:DesignInstance
IsDesignTimeCreatable=True, Type=src:MyType, CreateList=True}" but it also
didn't work

Thinkpad W530, cannot save to windows partition
Thinkpad W530, cannot save to windows partition
I recently purchased a Thinkpad W530 laptop from Lenovo with Windows 7 on
it. I installed Lubuntu 13.04 on it, and then mounted my OS partition in
Lubuntu 13.04. I have found that whenever I tried to save a file into this
partition (any file, any directory), Lubuntu seems to transfer or save the
files just fine, and I am able to edit them without any apparent errors in
Lubuntu. However, when I shutdown and reboot into Windows, not only are
those files GONE (not even hidden, actually gone) but when I shutdown and
reboot back into Lubuntu the files are gone there as well. In addition,
when I run a chkdsk in Windows, it shows that the files I transferred are
actually corrupted and must be deleted. I should mention that I had also
tried this same test by removing Lubuntu and using Xubuntu, with the same
results.
I have installed Ubuntu, Lubuntu, SUSE, and other distros on my previous
personal computers without any such problems ever arising. So, I am very
confused by this behavior. Does anyone have any advice regarding this
problem, or has anyone solved this problem on their own machines?

Help me understand the tensor product
Help me understand the tensor product
I have several books and other literature that define the tensor product,
but I understand none of them. Since this really concerns one topic,
namely understanding the construction of and arithmetic of (with?) tensor
products, I'll pose a few questions here instead of asking them
separately. I don't feel that the specific case of tensoring vector spaces
helps with understanding the general construction, so my questions will
deal with tensoring a right $R$-module with a left $R$-module over the
ring $R$, which we do not assume to be commutative.
1) Now then, the first step is to form the free abelian group $F(M \times
N)$. I've never stumbled upon free abelian groups prior to reading about
the tensor product, but it seems simple enough. Correct me if I'm wrong,
but $F(M \times N) = \{ \sum a_{ij}(m,n) \mid a_{ij} \in \mathbb{Z} \}$,
the sums ranging over all $(m,n) \in M \times N$. But some authors say
something else, which I trust is the same thing but nevertheless confuses
me. Keith Conrad (assuming $R$ is commutative) says $$R=\bigoplus_{(m,n)
\in M \times N} R \delta_{(m,n)}$$ without any mention of what
$\delta_{(m,n)}$ is, but it's probably similar to what I have in a
compendium (which also assumes the ring is commutative), "notation tagging
the component that corresponds to the element $(m,n) \in M \times N$".
What does that even mean, and why is that particular notation only used
when $R$ is assumed commutative?
2) Next define the subgroup $S \subset F(M \times N)$ generated by "all
elements of the following three types" $(a,b+b') - (a,b) - (a,b')$ etc.
Well, what does $-$ mean? Is an equivalence relation meant? If so, when
are they considered equivalent? I've only seen this along the lines of
"define $x,y$ to be equivalent if property $P(x,y)$ holds".
3) $M \otimes N$ is an abelian group. Fine, so how are elements "added"?
No mention of this is made in any of my literature, except that $a \otimes
(b+b') = a \otimes b + a \otimes b'$, but how about $a \otimes b + c
\otimes d$?
4) So-called elementary or pure tensors. Conrad writes "Tensors in $M
\otimes_R N$ that have the form $m \otimes n$ are called elementary
tensors". The elementary tensors span the tensor product (right?), but
what elements of $F(M \times N)$ wind up as elementary tensors? While my
compendium (which, as Conrad, assumes the ring to be commutative) also
makes note of elementary tensors, Rotman ("Introduction to Homological
Algebra"), not assuming commutativity, makes no mention of them, but says:
"Since $A \otimes_R B$ is generated by the elements of the form $a \otimes
b$, every $u \in A \otimes_R B$ has the form $u = \sum_i a_i \otimes b_i$.
This expression is not unique..." The other names for "elementary tensor"
which Conrad lists are not in the index to Rotman's book, so are
elementary tensors only relevant to tensoring over a commutative ring?
Thanks in advance for any help. I've had some homework regarding tensors
and I'm unable to take even a first step in answering the questions, so I
have to learn tensor products somehow.

IP Alias and port bridging
IP Alias and port bridging
The situation is that I have an Ubuntu box with multiple ethernet ports,
which I'd like to behave as if connected to the computer through a switch.
I can achieve this easily with a bridge. In /etc/network/interfaces:
iface br0 inet static
bridge_ports regex eth.*
address 192.168.1.1
netmask 255.255.255.0
Under this config, another device can plug into any of the ports and ping
this box at 192.168.1.1.
Now, the second part is that I'd like one of the ports to have an IP
alias, whereby it also tries to get a DHCP address. I can do this on eth0
without the bridge, like so:
iface eth0 inet static
address 192.168.1.1
netmask 255.255.255.0
iface eth0:0 inet dhcp
Now the trick is, how would I combine this with the software switch
functionality? Because brctl operates at layer 2, I can't create eth0:0
once eth0 is part of br0. The only thing I can do is create it as br0:0:
iface br0 inet static
bridge_ports regex eth.*
address 192.168.1.1
netmask 255.255.255.0
iface br0:0 inet dhcp
This actually does almost exactly what I'd like, but with one weird
problem: When the ethernet ports are disconnected or there's no DHCP
server, the bridge doesn't get its proper static IP---or it'll get it, but
not until a minute or two after the bootup is otherwise complete.
So my question is, what's up with the delay? Can I get rid of it somehow?
Alternatively, is there a better way I could accomplish what I want here?
The ideal thing would be a daemon which would periodically poll for DHCP,
and when it gets an IP assigns, puts it on the alias instead of the main
interface.
Thanks.

ui-view is loaded and replaced by some HTML. I want the page to be
scrolled down to the just-loaded part of the page. Is this possible?
Thanks in advance

Python, all possible combinations of numbers betweens 2 lists
Python, all possible combinations of numbers betweens 2 lists
i'm new to python and i would like some guidance with a problem i'm having.
Let's say you have two lists, with same length and filled with numbers
x=[0,1,2,3]
y=[0,4,5,6]
How can Python calculate the numbers between the numbers in the list at
the same position. So for this example.
[0,1,2,3]
[0,2,2,3]
[0,3,2,3]
[0,4,2,3]
[0,1,3,3]
...
I hoped someone with more experience would have some insight in this
matter. Thank you for your time and thoughts.

data structure in c that will hold an unknown length of cstrings and have
the ability to remove them latter
In C what's the best data structure for storing an unknown amount of
values then removing many? I'm reading a file and each line is stored as a
c string in some larger data structure. Each line is probably less than 20
characters long and one example file has 300000 lines. Whatever
datastructure I'm going to use will only grow in size at it's initial
creation; from there it will only shrink in size. What would I use? In
Java I would use ArrayList or maybe Vector. Could a dynamic array work and
if yes how would it look like?
char aLine[21];
char *data = malloc(aLine);
fp = fopen("datafile", "r");
if(fp== NULL)
exit(EXIT_FAILURE);
while(fscanf(fp, "%20s", aLine) == 1)
{
data = aLine;
realloc(data, sizeof(data)+sizeof(aLine));
}

putting multiple arrays into one single Liastbox
putting multiple arrays into one single Liastbox
I am trying to put multi arrays into a single listbox. Below is the code.
It works well when I make every output go into its own listBox but I am
trying to but them all in one listbox with the current headings. Can
someone help? One last thing, I would also like the duplicate values to go
into another column but don't know how. All I can due is just eliminate
the duplicates (want to go above and beyond and show what numbers were
eliminated)

How to visualize data in paraview with fortran
How to visualize data in paraview with fortran
I'm sorry I'm quite new to fortran therefore I don't know if this is out
of question. But I'd like to ask you for help. I wrote a program in
fortran which calculates molecular (basicaly their centers in 3d space -
xyz) movements. I'd like to visualize these data in ParaView, which I'm
capabl of. My programs output is VTK file which I can load into ParaView
and see everything I need clearly. But I'd like to somehow make this
process autonomous.
Basicaly I'd like to do computations and after some steps I'd like to
visualize molecules with ParaaView, take a screenshot from certain angle
save images as png (or any other img format which ParaView supports).
Because of a high number of iterations I can't do this myself, therefore I
thought about incorporating some kind of script into my fortran code or
any other way to make this happen, but I don't even know if this is
possible or how?
I do really hope you can help me I'm in a pinch here, I'm quite new to
fortran I hope I'm not asking for impossible.
I'd like to thank you very much for any help you can provide me with. (I'm
not asking for a prepared script, but for some hint/guide how to do this
if possible, but I'm not against examples either).

Convert Hex to Byte with big string
Convert Hex to Byte with big string
I tried the different ways to convert hex to byte, there are four methods
in the code, three of them i comment it out, only one there is no error
when i run it, but i confused that when i repeated to run the code, it
gave me the different result (should be generate "byte").
There is a question is when i use "method1", it gave me the result (byte),
but once i changed to "method2", it will not generate the result, i dont
know why. I thought it should generate same result, when i have same
string.

iOS custom CALayer class CRASH
iOS custom CALayer class CRASH
I'm trying to create custom drawn icons with this technique: Drawing
animated shapes and text in Core Animation layers
However that StarLayer sample is crashing (Message sent to deallocated
instance) and I can't find out what's wrong. StarLayer gets deallocated
somehow. I'm using ARC.
StarLayer is subclass of NSObject and it implements method:
- (void)drawLayer:(CALayer *)theLayer
inContext:(CGContextRef)context
Is that right approach to create custom icons using CALayers ?

How to change the default language of connect.microsoft.com?
How to change the default language of connect.microsoft.com?
I don't know whether or not this question is fitting SO.
I have found some bugs of the VC++ compiler, and I want to summit them to
Microsoft's official website: connect.microsoft.com
However, I am being located at China, so connect.microsoft.com always
returns web pages in Chinese. But I'm more familiar with English than with
Chinese. So I want to change the web pages' language to English.
The bad thing is: connect.microsoft.com will first determine the country
the client's IP belongs to, and next use the country's default language to
return web pages.
My question is: How to change the web pages' language of
connect.microsoft.com to any other one, say, English, German, Janpanese,
etc.?

Getting Started with CEF for the windows api
Getting Started with CEF for the windows api
I'm trying to get started using chromium embedded using the windows api. I
have managed to open and run the example project, but I have no clue of
where to go from there. The CEF wiki has no examples of use on windows,
and while I have found tutorials for gtk+ (
https://github.com/aphistic/cef3barebones ), it isn't going to help me
much with integration in the windows api. I am in the process of studying
the example application, but it is very complicated compared for the basic
functionality I a looking for Anybody have any adivice on what to do to
try an learn CEF on windows? Is there any tutorials on windows that I
haven't found yet?
Thanks for the help.

Seperating list by decimal in Python
Seperating list by decimal in Python
Here is my current list:
x = [1.0, 0.0, 3.5, 1.2, 5.4]
and here is what I want:
newx = [1, 0, 0, 0, 3, 5, 1, 2, 5, 4]
I just need to split the list at the decimal point and do not want any
extra zeros added to the new list. Seems like there should be a simple
solution I just don't know about since I am so new.

I have an app in appstore now im going to push out an update of app, Im
having a custom Plist file with set of values in my application bundle,
and these values are been modified from the version which is in production
and in addition even more key value pairs are added in to this file.
Now my doubt is on updating this app to appStore will the update process
automatically overrides(updates) my new plist file on top of existing one
or do we need to do some work around like how we do for database changes
like coredata migration and all?

Strange performance issues on iOS7
Strange performance issues on iOS7
I'm testing my app on iPhone 5 which runs iOS 7. Just for test purposes I
run 1000 iterations of cv::integral.
When on iOS 6 the results range were from 0.0005 to 0.0006 sec/iteration.
But on iOS 7 the timing range may differ from 0.0004 to 0.002
sec/iteration. A huge scatter.
It seems to be the OS scheduling bug. But is there any workaround, cause
my app heavily depends on performance?

XML view with relative percentages
XML view with relative percentages
I've been creating Android apps for well over 2 years, I've created games
and animated live wallpapers as well as using some basic XML to create
some settings. I've mainly used my own custom views written in JAVA using
the canvas class. Now I want to move across to XML views because of the
speed of development it offers.
Anyhow, I'm trying to figure out how to create an Android XML view using
percentages of the screen instead of DP.
Link to what I'm trying to say:
http://imgur.com/FZemLXy
What would be the best way of doing this? And can someone give me an
example? It needs to have the same percentages on every screen it's
displayed on.

iOS 7 : Disable UINavigationBar Translucency For Entire App
iOS 7 : Disable UINavigationBar Translucency For Entire App
Is there a way to disable UINavigationBar Translucency for an entire
application?
I'm aware that using [self.navigationController.navigationBar
setTranslucent:NO] can fix this issue for a single controller, but I have
a lot of UINavigationBars in my application and this is a pretty tedious
solution.
I've tried [[UINavigationBar appearance] setTranslucent:NO], but that
functionality is surprisingly not supported. Doing that results in
Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '*** Illegal property type, c for appearance setter,
_installAppearanceSwizzlesForSetter:'
If I HAVE to, I can go through my entire app setting UINavigationBars to
disable translucency one by one, but there must be some more elegant
solution to this issue...

Is there an equivalent to @property for containers in Python?
Is there an equivalent to @property for containers in Python?
I'm writing a simplified wrapper class in Python for an AWS module (Boto,
specifically). Several times in this process I've used @property to avoid
special "getter" and "setter" methods in my library - I'm told that this
is the more pythonic way to do it. When using the class, the programmer
call the methods as if they were simple objects, like this:
myclass.myprop = 5 # sends "5" to myprop's setter function
result = myclass.myprop # calls myprop's getter function and stores the
result
But I'm also dealing with several sets of objects - name/value pairs of
tags, for example - that I would like to access as if they were held in a
container, possibly a dictionary or a list. Taking the tag example:
myclass.tags["newkey"] = "newvalue" # runs a function that applies tag
in AWS
result = myclass.tags["newkey"] # accesses AWS to get value of
"newkey" tag
From what I'm seeing, it looks like it would be possible to do this by
subclassing dict, but I feel like I'm missing something here. What is the
most pythonic way to create an interface like this?

How to get week start dates and week number of each week in a year considering start day of the week is Monday in python?
How to get week start dates and week number of each week in a year
considering start day of the week is Monday in python?
How can I get week start dates of each week in a year, considering start
day of the week is Monday in python?
This assumes start day is Sunday:
>>>import datetime as datetime
>>>dt = datetime .date(2013,12,30)
>>>dt.isocalendar()[1]
1
However, result shouldn't be 1, because 30-12-2013 is still in 2013.

Sinatra - Calling a method based on the parameter passed
Sinatra - Calling a method based on the parameter passed
I have this specific route I want to implement in Sinatra:
post '/activate/:model/:id/?' do
model.activate stuff
basically what happens here is that I get the model name using
Module.const_get. I then call the activate method on the object. Now I
want to add a deactivate method, I can duplicate the code and just modify
it to be deactivate, but it's not very DRY-ish. I should probably use a
Regex, right? How do I "dynamically call a method" (aka call deactivate or
activate depending on the route?

postgresql transpose rows an columns misery
postgresql transpose rows an columns misery
I have gone through all of the similar topics and can't seem to solve my
problem. I have a table like this:
id[PK] key[PK] value
22 ingfs east1 22 storage stgeast1 23 ingfs east2 23 storage stgeast2 24
ingfs west3 24 storage stgwest3
I want to get:
ingfs storage
east1 stgeast1 east2 stgeast2 east3 stgeast3
I have tried the pivot table example but don't seem to be able to get
anything to work. Seems like this should be simple but I can't get my head
wrapped around it. Thanks in advance for any assistance.

Uncheck an html checkbox with for label
Uncheck an html checkbox with for label
I am using the following html to display a checkbox with an image:
Compare
I need to uncheck the checkbox in certain conditions. I am using the
following jquery : $('#111')[0].checked = false;
This works fine if I don't have the label. When I have the label, I don't
get any errors in console (either Chrome or Firefox), but the checkbox
does not uncheck.

R: Fitting a generalised logistic function
R: Fitting a generalised logistic function
I need some help fitting a generalised logistic function using R. For
reference, let's say the data looks roughly like this.
Initially, I tried nls using the following guide, however, I was having
trouble estimating initial parameters (i.e. receiving error messages; for
instance: singular gradient matrix at initial parameter estimates).
I next tried the package grofit (CRAN; viginette). Whilst I managed to
plot a line of best fit, it was poor as couldn't find a way to set the
lower asymptope to anything other but 0.
As I am not able to provide a working example, I don't expect a closed
solution, however, if someone could provide general advice (e.g. useful
packages, example code) that would be much appreciated.
Cheers

Grid view to stay intact once imageview image is changed
Grid view to stay intact once imageview image is changed
Hi I am developing a game in android where in the alpha value is changed
once the image in the imageview and the image in the grid view matches. if
the number of matches are equal to 4, i need to change the image in the
imageview and again compare with the images in the grid view.
I change the image in the imageview using imageView.setImageResource(q);
The image gets changed but the grid view disappears. Could you please tell
me what I need to do for teh grid view to change intact?
I tried gridView.invalidateViews(); but in vain. I also created a new
imageadapter with the same context but it still did not work. Any help
would be really great!

How can I pin down ASP MVC Razor profile using MiniPrfiler
How can I pin down ASP MVC Razor profile using MiniPrfiler
I have some views in my ASP MVC 4 web application that take several
seconds to render. I've install MiniProfiler to profile both the
controllers and Razor views. In one of my views I see the following
results:
duration (ms) from start (ms)
http://localhost:51405/Surveys/Details/201306... 4.8 +0.0
Controller: SurveysController.Details 2.2 +4.4
GetViewRows survey_with_tenant 6.1 +4.5
GetDocuments 5.7 +11.4
GetViewRows employees_by_surveyid 33.2 +17.2
GetDocuments 7.3 +51.4
Render : Details 1015.9 +59.4 <--- This is
the problem
Render partial: _LoginPartial 2.6 +450.2
The second to last line show that it took 1015 ms to render Details Razor
view. The partial used in it took 2.6 seconds, there are other partials
but they are even bellow 1 ms.
How can I further investigate what takes over 1 second to render?

Adding multiple text fields with the same code
Adding multiple text fields with the same code
I want to be able to add between 1 and 20 text fields to my view with the
same code.
My idea is to use a for loop and every time add a text field so the first
time it loops it adds "textField1" and the second time it adds
"textField2" etc.
I'm not sure how I would go about coding this so I'm looking for your help.

What does image gradient mean in the following paper?
What does image gradient mean in the following paper?
I am working in digital image processing using java, recently I am
implementing a paper in java, One portion of this paper is this:
What I have understood from that is, G(i,j) would be intensity of image at
location (i, j) after applying soble operator on it, does it mean so or
anything else,
I have used the following code to compute wG,
public void weightedGCalc() {
BufferedImage sobelIm = this.getSobelImage();
int width = sobelIm.getWidth();
int height = sobelIm.getHeight();
weightedG = new double[width][height];
for (int row = 0; row < width; row++) {
for (int col = 0; col < height; col++) {
int imgPix = new Color(sobelIm.getRGB(row, col)).getRed();
float val = -(float) (Math.pow(imgPix, 2) / (2 *
Math.pow(SIGMA_G[5], 2)));
weightedG[row][col] = (float) Math.exp(val);
}
}
}
Here this.getSobelImage(); will give me sobel Image of a given image. I am
working with gray level images hence i am considering only one plane
(RED). Here SIGMA_G[5] contains value of sigmaG as suggested by Author.

How to get readable string from mysql with node.js?
How to get readable string from mysql with node.js?
When user register, i save its name in mysql (russian name in database

X-axis labels are not displaying properly
X-axis labels are not displaying properly
I have created following dummy rCharts:
My_Data <- data.frame(Names = sapply(1:26, function(x)
return(paste(sample(letters, 26), collapse = ""))), Att1 = LETTERS, Number
= 1:26)
n1 <- nPlot(Number ~ Names, group = "Att1", data = My_Data, type =
"multiBarHorizontalChart")
n1$params$height = 5000
n1$params$width = 1000
n1
However when this plot is displayed in browser, the names in the x-axis
are not visible clearly. Those names are lengthy by how they have been
created in my original requirement. Can someone point me how to display
the full names?
Your help will be highly appreciated.

In my database I have table that has just two fields, ID and this XML. So,
when I insert new XML, i have to find out if there already exists XML with
this location, and where date from first Forecast parts are same. Is there
any way I can read only Date from first Forecast child of this root
element Weather? I know I have to go through my table and search every XML
file I have, and that's not problem, but what I need is just date from
only first forecast child.

Aggregate function calls cannot be nested
Aggregate function calls cannot be nested
I am consulting the docs from
http://www.querydsl.com/static/querydsl/3.2.1/reference/pdf/Querydsl_Reference.pdf
There I see the example
QDepartment department = QDepartment.department;
QDepartment d = new QDepartment("d");
query.from(department)
.where(department.employees.size().eq(
new JPASubQuery().from(d).unique(d.employees.size().max())
)).list(department);
I tried to execute the query using my tables with the code below:
QAdminEntity tableAdmin = QAdminEntity.adminEntity;
JPAQuery query = queryFrom( tableAdmin ).where(
tableAdmin.id_city.eq( idCity ).and(
tableAdmin.problems.size().eq(
subQueryFrom( tableAdmin ).unique(
tableAdmin.problems.size().min()
)
)
)
);
return query.singleResult( tableAdmin );
That code gives me an error, something like "Aggregate function calls
cannot be nested".
I am sorry for my lack of expertise on postgres and querydsl, but I
suppose this should be very straightforward.
The resulted query:
select
adminentit0_.id_admin as id1_3_,
adminentit0_.ds_email as ds2_3_,
adminentit0_.ds_name as ds3_3_,
adminentit0_.ds_password as ds4_3_,

select
min(count(problems3_.id_admin))
from
m_admin adminentit2_,
m_problem problems3_
where
adminentit2_.id_admin=problems3_.id_admin
) limit ?
As you can see I want to list the admin that have less problems than
everyone else from the relation admin -> problems.
How can I make this work?
Adittional question:
Is it necessary to get another "QAdminEntity" field for the subQuery or
that "new QDepartment("d")"code is just for the example?

I want to replace a word in a string with another word. Ex.
replaceWord("cool","awesome","Stack overflow is cool.") Output would be:
"Stack overflow is awesome" I don't understand why my code isn't working.
def replaceWord(oldWord,newWord,aStr):
aStr.replace(oldWord,newWord)
return aStr

Toggling jquery submenu items
When I am trying to toggle the SubMenu item, the item toggles but the
first level menu is closed. The menu should not hide when the person
clicks on the sub menu item. for example if you click on SSNIT and goto
"core services" the sub menu appears but the first level menu item is
closed. Need some expertise for this fix? You can view the code on
JSFiddle here http://jsfiddle.net/3aRSr/.
