Javascript return enclosing function
I have a simple scenario in which I check if something exists before
adding it, if it does, I return the function (hence exiting). I use this
pattern many times and I would like to decouple it in another simple
function.
function onEvent(e){
if( this.has(e) )
return
this.add(e);
// More logic different on an event-basis
}
I would like to decouple it like so:
function safeAdd(e){
if( this.has(e) )
return
this.add(e);
}
function onEvent(e){
safeAdd(e);
// More logic
}
But obviously doing so just returns safeAdd and doesn't exit from onEvent,
and the rest of the logic gets executed anyways.
I know I could do something like:
function safeAdd(e){
if( this.has(e) )
return false
this.add(e);
return true
}
function onEvent(e){
if( !safeAdd(e) )
return
// More logic
}
But, since I repeat this a lot, I would like to be as concise as possible.

Selecting distinct within a select statment.
Selecting distinct within a select statment.
Hi in the following select statement I want to select the distinct values
b.bId for one of the column and not working. Statement is
select
a.sId
,distinct b.bId
from tlocal a
left outer join ts b on (b.id=a.mainId)
where
a.id=@xId;
I have to select the distinct in the select statement since this is
returning values in a stored procedure. Let me know please, thanks

how migrate to ember.js existing page with lot of js
how migrate to ember.js existing page with lot of js
I have start to make a full application using jquery ui and jsplumb. I
want ot make an application which use a lot of ajax and manage model on
client side. I have start to code it manaually. And I discover ember js
and angular. It fit perfectely to my need to have model on client side and
do ajax to save load data. I choose ember for different reason
(handlebars, no intrusive attribut, ...) I have read the documentation and
few tutorial. I see how we make a page and fill it with data from
controler/model. But where do we put code to make the view dynamic. I
mean, we have jqueryui and all things which add dragNDrop, effect,...
which manipulate DOM. I know that ember try to avoid that and prefer
template over dom manipulation but I have ever code that with jquery js
and do not see how to migrate that code to ember. To sum up: I need drag
and drop/ dom manipulation when click on button or when drop element. I
need to handle dbl click to load modal window (loaded in ajax) and del key
to delete content in dom. All this things are easy with jquery/jqueryUI
but do not see where to put that in ember.
My code is to big to be paste here.
Is it possible to load JS script to manage each view ? this js must only
be linked to the view content. To avoid id/class selector colision between
pages.

Using summary function in R and applying to particular cases
Using summary function in R and applying to particular cases
Just self-learning R at the moment and have gotten a little stuck. I have
a dataset and I want to summarize (find mean, max, etc) but only selecting
those cases that have a particular value on a certain variable.
Alternatively, I guess the same outcome could be done by summarizing only
certain rows in the dataset (ie summarize only rows 1 thru 20).
Could someone lend a helping hand? Thanks so much

R: return one TRUE / FALSE from a group of boolean values
R: return one TRUE / FALSE from a group of boolean values
Suppose:
mu.iter <- c(3,3,3,3)
mu <- c(1,4,1,4)
> abs(mu.iter - mu) > 1.5
[1] TRUE FALSE TRUE FALSE
Instead of four TRUE/FALSE values, I just want one TRUE / FALSE value,
such that it only returns TRUE when all 4 are TRUE and FALSE otherwise.
The reason is that I want to put this into a while-loop.

Approved method to navigate between pages on same website
Approved method to navigate between pages on same website
I have researched many places to find an answer to this question, but they
never quite answer my real question: What is the best/approved way to move
to a new page within the same website? I have read that it is bad to use
window.location because search engines will think you are hiding
something. But, when I don't want to open a new window (window.open), then
I don't know how else to do it. I use href anchors in links and form
actions, where appropriate. But when I have menus or buttons with onclick,
then I need something else.
Here's an snippet of my code:
my javascript: (with one option commented)
function gotoCat() {
var catcdF = document.catSelect.catcd.value;
<?php
echo
"window.location.href='http://www.mysite.org".$pgmdir."services/busMenu.php?catF='+catcdF;
";
/*
echo
"window.open('http://www.mysite.org".$pgmdir."services/busMenu.php?catF='+catcdF,'','resizable=1,scrollbars=1,toolbar=1,top=50,left=300,width=950,height=800,location=0');
";
*/
?>
}
My dynamic SELECT list in a form (within PHP):
echo " <select name='catcd' id='catcd' size='8' onclick=gotoCat() > \n";
// display list of categories
if ($numcats == 0) { // print message text only
echo "<option value='0' >".$catMsg."</option> \n";
}
else {
for ($i=1; $i<=$numcats; $i++) {
$catcd_db = $catAry[$i][1];
$catName_db = $catAry[$i][2];
echo "<option value='".$catcd_db."'> ".$catName_db." </option> \n";
}
}
echo "</select>";
So, as you can see, I just want a method to allow the user a choice and
then automatically go to the correct web page once selected. This is not
always in a select list. Often it's when they want to exit or get an
error:
if (mysqli_connect_errno()) {
echo "<br/> <p style='text-align:center;'> <button type='button'
class='buttonStyle' style='padding: 4px 20px;' value='Exit' ";
echo
"onClick=\"window.location.href='http://www.mysite.org/services/catSelbus.php?rc=1&func=Rev'\"
> ";
echo "Exit </button></p> ";
}
I cannot use "go back" because they need to go to a prior page, not the
form they came from.
So, unless my navigation methods are really off-the-mark, I guess I need
to know the acceptable method for using javascript onClick to move to the
next page in the same website. Is window.location okay, or should I use
something else?
Any opinions or suggestions are welcome!

Why can I execute an Android application with which is compiled against

clarify?

Sharing small data using Windows shared memory
Sharing small data using Windows shared memory
I'm looking for advice and suggestions for storing small amounts of data
(only a few bytes) in a shared memory segment on Windows.
Right now, whenever we map shared memory, we round the mapping size up to
the nearest 4KB so we get a multiple of pages mapped.
mem_size = ((mem_size + 4095) / 4096) * 4096;
However, I want to map enough memory to share a named integer between
processes. Or more specifically, many differently-named integers between
processes. About a thousand integers, all with different names and each
one mapped by one or more processes is what I'm looking at.
I don't want to round 4 bytes up to 4KB because this would be a huge
waste. After creating a thousand or so of these, I would have used about a
thousand pages when I only needed one.
But I am worried about the overhead of creating a named memory segment for
just 4 bytes. Will the OS be "reasonable" enough to try and fit the
different mappings onto the same page where possible? (There are no
guarantees, I know). Or will this quickly blow out?
I had considered mapping one huge block of memory, but the individual
integers still need to be referred to by name. Maintaining a hash table
inside shared memory seems like I'd just be duplicating the work of the
OS.
Is there an alternative to the CreateFileMapping/OpenFileMapping and
MapViewOfFile technique that would be more suited to sharing very small
amounts of data between processes? Or am I worrying over nothing?

submit form to new tab and close modal
I am submitting a form to a new tab from a modal window. I want the form

new tab opens fine and the modal does not close. I am using this same js
in a modal php script with RefWin() as the last line and when the script
ends, the modal closes and the parent refreshes. The modal window is a

attempted using onsubmit and onclick and neither work. I know there is a
simple answer to this and I am stumped... appreciate some assistance.

AngularJS $http response long execution
AngularJS $http response long execution
I am using Angular and $http request to get data from server. It is mock

way to long. The request is executed on application start up. I have tried
to execute the same query using jQuery $.ajax, and it worked in 10 ms. But
I am want to get rid of jQuery. Why AngularJs $http is taking so long?

Rails 3 session variable not deleting right away using cache storage in production
Rails 3 session variable not deleting right away using cache storage in
production
I am using the cache store for session storage in Rails 3. In production
deleting a session variable doesn't seem to be reflected until the request
has completed. That makes sense for cookie storage, but not for cache
storage. Also, this isn't a problem in staging which makes me think it's a
config issue. I'm not sure what config parameter would cause this, though.
Any ideas?
Here's the action code. The variable is cleared because the user can add
more things to the session while the first request is being processed, but
the session variable can't overlap between requests.
id_list = session[:batch_select_ids]
#Clear the session variable
session.delete(:batch_select_ids)
Thanks.

Regular expression that match decimal places
Regular expression that match decimal places
I have this code to test if a value entered in a INPUT is numeric:
$("#price").val().match(/^\d+$/);
I need some help rewriting this function to allow decimal places either
with colon or dot meaning for example 230.00 is allowed and 230,00 is
allowed too. Also the decimal places could be four or less. Any?

Windows 8 : Force a static IP adress only for a specific network
Windows 8 : Force a static IP adress only for a specific network
I am a developer. I need to have a static IP adress when I'm at my office,
and would like to use my DHCP at home.
Making a reservation on the office's DHCP isn't possible (the router they
have doesn't allow that).
I've looked up through Google to see if there is something that could suit
my needs but haven't found any (Maybe it's because I don't know the name
of the technology I'm looking for).
So my question is: Is there a way to automaticly switch from a static
address to a dynamic depending on the network?

Using xslt, how to add an xml node that starts before the first occurrence, and ends after the last occurrence of an item?
Using xslt, how to add an xml node that starts before the first
occurrence, and ends after the last occurrence of an item?
I have an xml that looks like this:

<Item>
<Name>Apples</Name>
<Price>1.00</Price>
</Item>
<Item>
<Name>Oranges</Name>
<Price>1.00</Price>
</Item>
<AdditionalInfo>...</AdditionalInfo>
</ShoppingList>
I would like to wrap the "items" into a GroceryList, like so:
<ShoppingList>

How would I go about doing that using xslt? There is only one sub-list
inside of "ShoppingList".

Gnome is not working properly after messing around with compiz
I fixed tearing for my tv and something went wrong.
Im using multiple screens. I turned of opengl and composite in compiz
config. Now all my windows do not work, i can se programs in the bottom
navbar but just firefox is displayed.
I cant see terminals and "CompizConfig settings" etc..
I tried to fix the problem by resetting compiz(i think its what this does):
gconftool-2 --recursive-unset /apps/compiz
It did not have any effect. What am i doing wrong here? can i somehow
reinstall/reset this?

Is it a myth that id reuse in an html document is a w3c standard violation?
Is it a myth that id reuse in an html document is a w3c standard violation?
I was inspecting the way a certain webpage alternated between colors in
their divs and found this:

Thinking this was an example of html that wouldn't validate, I ran it
through the w3c validator (http://validator.w3.org/). It did have errors,
but none were regarding non-uniqueness of the ids. Everything I've read
has stated that ids must be unique within a webpage. What's the real story
here?

Automaticaly commit when updating pacemaker configuration
Automaticaly commit when updating pacemaker configuration
I'm trying to automate the administration of my servers which are running
corosync/pacemaker. For that I generate a file containing the modifs that
needs to be applied to the configuration. To apply this file I usualy do :
crm configure load update path_to_file
It works fine when I do it myself. But whenever there is a warning
generated by the config, crm ask if I really want's to commit the changes.
As far as I'm trying to automate this task I'd like to get rid of this
question and directly commit the changes. Is-it possible ?

needs to be applied to the configuration. To apply this file I usualy do :
crm configure load update path_to_file
It works fine when I do it myself. But whenever there is a warning
generated by the config, crm ask if I really want's to commit the changes.
As far as I'm trying to automate this task I'd like to get rid of this
question and directly commit the changes. Is-it possible ?
Making sure that opening app from widget does initialization
Making sure that opening app from widget does initialization
I have a widget, and whenever it is clicked, my app opens. I want to make
sure it loads the correct item (the item that the widget shows). My
current code for setting up the intent looks like this:
intent.putExtra(NuggetActivity.DAY_NUMBER, todayLong);
intent.putExtra(FROM_WIDGET, true);
PendingIntent pendingIntent = PendingIntent.getActivity(context, (int)
todayLong, intent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.container,pendingIntent);
The app loads fine when the app is loaded from onCreate() onwards, but not
when the app resumed (through onResume()).
Is there some flag I can set in my intent to make sure that onCreate()
gets called, or is there some other way to solve this?

The primary selection criteria for choosing FM vs. AM is dynamic range
The primary selection criteria for choosing FM vs. AM is dynamic range
The primary reason for selecting FM over AM is the ability of FM to
support a greater dynamic range by spreading the information across a wide
range of frequencies, and using more 'horizontal information carrying
capacity'.
Trying to increase the dynamic range of an AM signal would require
impractical levels of power to be used to represent the same information
carrying capacity in a 'vertical' or amplitude modulated scenario?
Yay or nay.

Help with a simple problem involving a functional inequality (trying to prove Gronwall's inequality)
Help with a simple problem involving a functional inequality (trying to
prove Gronwall's inequality)
So while trying to prove Grownwall's inequality, my proof led me to the
following statement: $h'(x) \le h(x)g(x)$.
Now when $h'(x)=h(x)g(x)$ the following holds: $h(x)=k \exp G(x)$, where
$k$ is a constant number. Can I conclude from this that $h(x) \le k \exp
G(x)$ (since $h'(x)<h(x)g(x)$)?

How to Create a Custom Pivot Title Style
How to Create a Custom Pivot Title Style
I would like to be able to create a custom pivot page title style in my
application, so that I may use it across multiple pages. Essentially I
just want the title of the Pivot to be centered with a certain font size
and type. Originally I was using an Image for my title but I really need a
text title instead. How might I go about doing this? I've already tried
setting this within App.xaml and using it within my MainPage.xaml but so
far I don't have anything working.

Nested Single Query for concatenation of specific column in multiple row in single column
Nested Single Query for concatenation of specific column in multiple row
in single column
i have currently working on sql server and writing a stored procedure to
retrieve some data. My requirement is as follows:
Table A:PersonId,FirstName,LastName,Address,CourseId
(Primary Key For Table B,Foreign Key Here)
Table B:CourseDescription,CourseId
now for each course there might be multiple student enrolled to that
course.my requirement is to concatenate each student LastName,FirstName.if
there are 3 or more student in a course we have to set another flag value
as 'Y' in the result.I've done with Stored proc using temp table , and
updating it step by step. my stored proc algo is like this: temp table has
column:
SeqId,CourseId,CourseDescription,StudentNameConcat,IsMoreThan3
First i update course id,description.then from this table i looped based
on sequence id(SeqId) and retrieve list of student name as column value
and concat it in declared variable.
This approach is not good because it is not a set based approach.and i
believe there must be an alternative approach for it in a single query
using inner query or loop join.I'm still reading and trying to implement
it in a single query.But still not getting any clue.

Renamed folder still shows up in Explorer - How to clear Windows Folder Cache?
Renamed folder still shows up in Explorer - How to clear Windows Folder
Cache?
I have renamed "Downloads" folder to "OldDownloads" from my D: Drive, and
when I issue dir command in command line, I see that Downloads folder is
renamed to OldDownloads and when I try to issue command "cd downloads" I
get an error.
However, when I open Windows Explorer, I still see Downloads folder and I
dont see OldDownloads folder.
When I double click on any file inside "Downloads" folder, I get an error
saying file does not exist. I wrote a custom c# command line program to
access file from "OldDownloads" folder, I can access it fine.
It seems, folder is successfully renamed, but however Windows Explorer
still remembers old folder name and gives wrong path to programs.

Captions and labels for my tables, listings, images
Captions and labels for my tables, listings, images
I'm writing my master thesis and I have a lot of short tables, listings,
etc. in the text.
I would use figures for them like this:
\begin{figure}[h!]
\begin{lstlisting}[mathescape]
... my listing here ...
\end{lstlisting}
\caption{... caption ...}
\label{... label ...}
\end{figure}
\begin{figure}[h!]
\begin{tabular}{|l|l|}
... my table here ...
\end{tabular}
\caption{... caption ...}
\label{... label ...}
\end{figure}
etc, but the fact that LaTeX moves them to another page (even though they
are sometimes very short) makes the text hardly readable.
I would need LaTeX to keep them at exactly the same spot (if they fit
there) or at the top of the next page (otherwise). It is my understanding
that I should not use figures in this case. But, on the other hand, I
would like to keep the captions, labels and numberings for them to still
be able to address them.

sum of two independent exponential distribution
sum of two independent exponential distribution
let $Y_1\sim \exp(\lambda_1)$ and $Y_2\sim \exp(\lambda_2)$ and $V=Y_1+Y_2$
Show that the pdf of $p_V(x)$ of $V$ has the following form
$$p_V(x)=\frac{e^\frac{-v}{\lambda_1}-e^\frac{-v}{\lambda_2}}{\lambda_1-\lambda_2};\quad
v\ge0$$
My attempt:
distribution of $Y_i$,
$$p_{Y_i}(y_i)=\frac{1}{\lambda_i}e^\frac{-{y_i}}{\lambda_i};\quad
x\ge0;\quad i=1,2$$
joint distribution of $Y_1$ and $Y_2$,
$$p_{Y_1,Y_2}(y_1,y_2)=\frac{1}{\lambda_1\lambda_2}e^{\frac{-{y_1}}{\lambda_1}-\frac{{y_2}}{\lambda_2}};\quad
{y_1},{y_2}\ge0$$
Given, $V=Y_1+Y_2$
let $U=Y_2$
So the Jacobian of Transformation is $1$
and hence joint distribution of $V$ and $U$,
$$p_{V,U}(v,u)=\frac{1}{\lambda_1\lambda_2}e^{\frac{-{v-u}}{\lambda_1}-\frac{{u}}{\lambda_2}};\quad
{v},{u}\ge0$$
so the distribution of $v$ $$p_{V}(v)=\int_0^\infty
p_{V,U}(v,u)du=\frac{e^\frac{-v}{\lambda_1}}{\lambda_1-\lambda_2};\quad
v\ge0$$
which doesn't match with the result.

Extract problem and solution from files and create problem collection
Extract problem and solution from files and create problem collection
I have a set of problems and solutions, which I wish to include in several
different documents. I would like to be able to choose if the solutions
should be presented last, or immediate after the problem formulation.
A possibility is to put each problem and solution in a separate file, and
then have some command
\includepart{filename.tex}{problem}
and
\includepart{filename.tex}{solution}
where \includepart{file}{env} includes say everything between
\begin{env}and \end{env}.
Is there a simple way to do this? Are there better solutions to this? This
seems to be a common problem, but I have not found something that does
exactly this.

Dynamically Load External Webpage
Dynamically Load External Webpage
I see this site and many others answering similar questions, but often in
ways I fail to understand or just do not make sense. And often in
contradictory ways (maybe the spec keeps changing?). And I see posts about
how to set up cross domain JavaScript communication, but I do not need to
communicate with this external content (and I am still not sure if you
must have access to the code-base of both child and parent or not, for
these hacks to work).
I need to show another person's webpage, on another domain, in a box on my
page. SO basically this is like clicking a link, but instead of specifying
that the browser should open this in a new tab or a new window, I want the
browser to open it in a in-line frame type deal on the current page. So
even I know enough about security to know that there are no
security/communications issues with this feature.
But assuming that the browser developers have removed this completely
reasonable feature, how do I go about doing this? I have heard talk about
some Json data type thing being allowed, but still have not figured out
exactly what that means. Can I contact any random external page and get
some json summery of the page, or how does this work? (I saw an example
with Wikipedia, but I was not sure exactly what was being returned, and if
any random URL would work just as well).
I can use PHP for this, but that is just stupid. I would basically just be
setting up a proxy to access content I am randomly banned from because of
the programming language I am trying to access it from.

XBOX 360 Arcade multiple USB flash drives
XBOX 360 Arcade multiple USB flash drives
Recently I grabbed rather old XBOX 360 Arcade for my son who wanted to
play Minecraft that is not yet available on PS3. This console doesn't have
much internal storage and after resetting and applying latest updates,
only about 24 MB is left. I read that I can either add external HDD or USB
flash drive to it. I have couple of spare USB drives and one of them
actually worked. It is small (4GB) and I am planning to add more. This is
my secondary console so I don't want to spend too much money on it. Few
questions...
I see 3 USB ports so can I put three USB flash drives of 32GB each if I
wanted to?
I am thinking about not getting HDD storage at all as it is more expensive
and very specific to XBOX. USB flash drives are multi-purpose and I could
use those elsewhere after the console dies or I don't want to use it
anymore. Any downside to this?
I would like to buy games from live account instead of on physical disks.
The table in the link seems to indicate that it is supported but I wanted
to confirm as some older articles say otherwise. It seems like this
support was added much later after the console was released.
Can the installed game be moved from one flash drive to another?

anymore. Any downside to this?
I would like to buy games from live account instead of on physical disks.
The table in the link seems to indicate that it is supported but I wanted
to confirm as some older articles say otherwise. It seems like this
support was added much later after the console was released.
Can the installed game be moved from one flash drive to another?
Text formatting for strings in Google Documents from Google Apps Script
Text formatting for strings in Google Documents from Google Apps Script
I have some Google Apps scripts that use the DocumentApp .replaceText
method to find a text string in a Google Document and replace it with a
different text string.
var file = DocsList.getFileById('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');
var newTextString = 'foo\nbar';
file.replaceText('Old text string',newTextString);
The \n works to make line breaks, but is there a way to format the text
with bold/italics/colors/etc?
I tried to use HTML tags and inline CSS styles with the span tag, but that
didn't work, it just outputs the text including the tags. I remember how
Google Docs used to have an HTML button and you could see the markup that
made up the content of the Google doc, but they took that out.

How does one send a chat message in Facebook using jquery within the Chrome browser?
How does one send a chat message in Facebook using jquery within the
Chrome browser?
I'm trying to send a chat message in Facebook using jquery, but keep
getting an error message. Either it being "TypeError: Object # has no
method 'WHATEVERIPUTHERE'"
[Note that I'm pretty new with coding.]
// Basically o = the chat text area.
// the o.WHATEVERIPUTHERE("Hello!") is what I'm trying to do (setting a
value for the text area, and sending it)
I have no idea how to get this to work as my method knowledge is limited.
Basically, I just need help exapnding on this to make this a workable
code. Thanks! [code below]
var o = document.getElementsByClassName("uiTextareaAutogrow _552m");
o.WHATEVERIPUTHERE("Hello!");

Why shall I explicitly cast null for the invocation of a varargs method?
Why shall I explicitly cast null for the invocation of a varargs method?
I've got the following code:
public static void varargsMethod(String ... strings) {
if (strings != null && strings.length != 0) {
for (String s : strings) {
System.out.println(s);
}
} else {
System.out.println("Hello (string free) world!");
}
}
public static void main(String[] args) {
varargsMethod(null);
varargsMethod((String[]) null);
varargsMethod((String) null);
varargsMethod();
}
I wonder why the first invocation with null as the argument generates a
warning with the hint, that an explicit cast is needed. From the answers
on this question it is not clear for me, why this cast is needed. The
first two invocations work and produce the same result, while the third
produces "null". I explicitly want the behaviour of the first two
invocations.
Shouldn't null be always valid (and automatically casted) for reference
types and arrays? I don't see, why the type information is important in
this case.

I'm watching this Google I/O presentation from 2011
https://www.youtube.com/watch?v=M3uWx-fhjUc
At minute 39:31, Michael shows the output of the closure compiler, which
looks like the code included below.
My question is what exactly is this code doing (how and why)
// Question #1 - floor & random? 2147483648?
Math.floor(Math.random() * 2147483648).toString(36);
var b = /&/g,
c = /</g,d=/>/g,
e = /\"/g,
f = /[&<>\"]/;
// Question #2 - Looks like sanitizing input... yes?
function g(a) {
a = String(a);
f.test(a) && (
a.indexOf("&") != -1 && (a = a.replace(b, "&")),
a.indexOf("<") != -1 && (a = a.replace(c, "<")),
a.indexOf(">") != -1 && (a = a.replace(d, ">")),
a.indexOf('"') != -1 && (a = a.replace(e, """))
);
return a;
};
// Question #3 - void 0 ???
var h = document.getElementById("submit-button"),
i,
j = {
label: void 0,
a: void 0
};
i = '<button title="' + g(j.a) + '"><span>' + g(j.label) +

h.innerHTML = i;

JQuery scrollTop values fadeIn/Out
JQuery scrollTop values fadeIn/Out
I have this code so that my '.button' would fadeIn if the 'scrollTop > 200'.
$(document).ready(function() {
$(window).scroll(function() {
if ($(this).scrollTop() > 200) {
$('.button').fadeIn(500);
} else {
$('.button').fadeOut(500);
}
});
});
What I want to happen is I want '.button' to fadeIn if it's on a certain
part of the page, and fadeOut if it's out of the specified part. For
example:
$(document).ready(function() {
$(window).scroll(function() {
if ($(this).scrollTop() 200 - 500) {
$('.button').fadeIn(500);
} else {
$('.button').fadeOut(500);
}
});
});
Basically, I want ".button" to disappear if it's outside of the values given.

How to prompt user for input and use input else where in batch file
How to prompt user for input and use input else where in batch file
I am very new to batch scripting. I am trying to prompt a user to "Enter
directory path containing files to be converted:". Once they enter that I
want to prompt them to "Enter directory path to save files to once
converted:". My code currently prompts the first question, but then closes
before the user can input anything.

Importing a hyper-v exported image
Importing a hyper-v exported image
My google-fu is failing me. Badly.
One of my clients sent me a Hyper-V exported VM which constitutes a bunch
of VHDs and an XML file (which I assume is the machine definition file).
Try as I might, I can't figure out how to import this machine or convert
it into a format compatible with any of VMWare Workstation, Virtual Box or
even Windows Virtual PC. Googling and searching the fora for a few hours
has not yielded any satisfying answers.
Can anyone direct me as to how to properly import said Hyper-V exported VM
into any of VMWare Workstation, Virtual Box or Windows Virtual PC please?
Thanks

Chained select boxes with jquery/php/database not working
Chained select boxes with jquery/php/database not working
It seems that most chained selects are accomplished with JSON, but
unfortunately it's much more convenient for me to use my database to
accomplish this. It's almost there, but for some reason the second select
box is not loading up properly. Instead it's loading the entire HTML for
the page that it's on and I'm not sure why.
Here's what I've got (note that make_list() and model_list() are functions
I previously built that return an array appropriate to their respective
criteria)
The JS:
$(document).ready(function(){
$("select#type").attr("disabled","disabled");
$("select#category").change(function(){
$("select#type").attr("disabled","disabled");
$("select#type").html("<option>loading...</option>");
var id = $("select#category option:selected").attr('value');
$.post("select_type.php", {id:id}, function(data){
$("select#type").removeAttr("disabled");
$("select#type").html(data);
});
});
$("form#select_form").submit(function(){
var cat = $("select#category option:selected").attr('value');
var type = $("select#type option:selected").attr('value');
if(cat>0 && type>0)
{
var result = $("select#type option:selected").html();
$("#result").html('your choice: '+result);
}
else
{
$("#result").html("you must choose two options!");
}
return false;
});
});
The HTML/PHP:
<form>
<div class="clearfix">
<select id="category">
<option value="">Any</option>
<?php foreach ( make_list() as $make ) { ?>
<option value="<?php echo $make ?>"><?php echo $make ?></option>
<?php } ?>
</select>
</div>
<div class="clearfix">
<select id="type">
<option value="">Any</option>
</select>
</div>
</form>
When the first select is changed JQuery should look at a file in the same
folder called 'select_type.php'. Here's what's in that file (strangely
$_POST['id'] doesn't seem to be appending to this file either, despite it
being created in the JS):
foreach ( model_list($_POST['id']) as $model ) {
echo '<option value="'.$model.'">'.$model.'</option>';
}
I've been using this resource for this project:
http://www.yourinspirationweb.com/en/how-to-create-chained-select-with-php-and-jquery/
and it's gotten me most of the way, but unfortunately the data doesn't
seem to be loading into that second select box.

Is there an emacs extension that automatically updates the browser?
Is there an emacs extension that automatically updates the browser?
I am working on HTML/CSS/JavaScript from within emacs. My workflow is
currently
Make a change -> Alt-Tab to browser -> F5 (refresh) -> Alt Tab to emacs
Do any extensions exist that would auto-refresh the browser on a change?
Or, possibly a better idea, when I hit a key combination from within
emacs?

set MAX_WRITE_SIZE for php_curl.dll because of slow transfer rates
set MAX_WRITE_SIZE for php_curl.dll because of slow transfer rates
I have really slow transfer rates when posting files with curl in php on
several versions and machines. I've read that this can be solved by
changing the set MAX_WRITE_SIZE setting in curl. But I use the
php_curl.dll, is there any way to set MAX_WRITE_SIZE for php_curl.dll? It
is not a problem with the connection, it is not a problem with the code,
it seems to be a problem of windows.
Thank You!

Javascript Create Json
Javascript Create Json
I'm trying to create and post a json message in the following format:
var listObjects = [];
$.each(results, function(index, value){
var item = new Object();
item.title = value.Title;
item.code = value.Code;
listObjects.push(item);
});
var jsonResult = JSON.strringify(listObjects);
basically this will create my json like this:
[{"title":"Product 1","code":123456789012},
{"title":"Product 2","code":123456789012},
{"title":"Product 3","code":123456789012},
{"title":"Product 4","code":123456789012},
{"title":"Product 5","code":123456789012},
{"title":"Product 11","code":123456789012},
{"title":"Product 12","code":123456789012},
{"title":"Product 13","code":123456789012}]
how can I do it so that if I want to add some metadata to my json that
will not repeat for each item but just at the top ... something like this:
category: x
type: y
...
items:
title: .....
code: ......
so basically the category and type will define the whole items in the json
but are not repeated for each item ...

getting uv-Coordinates from THREE.js DataTexture
getting uv-Coordinates from THREE.js DataTexture
I am trying to implement a small Volumerenderer with THREE.js. For that I
have a large(at least 65000 elements) array with intensity-values(too
large to pass as a uniform array) to the shader where raycasting and all
that will happen. I wanted to use THREE.DataTexture for that but I don't
seem to have any uv-coordinates in the shader and get the following error:
Error: WebGL: vertexAttribPointer: must have valid GL_ARRAY_BUFFER binding
Error: WebGL: drawArrays: bound vertex attribute buffers do not have
sufficient size for given first and count
This is my setup:
In the init-function:
var data = new Uint8Array(textureArray);
var texture = new THREE.DataTexture(data, 128, 128, THREE.AlphaFormat);
texture.needsUpdate = true;
uniforms = {
texture: {type: "t", value: texture}
}
in the vertex-shader:
varying vec2 vUv;
void main(){
vUv = uv;
}
in the fragment-shader:
uniform sampler2D texture;
varying vec2 vUv;
The shaders are for a THREE.ShaderMaterial on a particleSystem. Everything
works fine as long as i don't have the vUv = uv assignment in the the
vertex-shader and the Texture works when I put it on a Cube like this:
cube = new THREE.CubeGeometry(10,10,10);
material = new THREE.BasicMaterial({map: texture});
mesh = new THREE.Mesh(cube, material);
scene.add(mesh);
Has anybody had a similar problem or an idea where my mistake could be?

Flipping image causes massive RAM/CPU uses with AForge.net
Flipping image causes massive RAM/CPU uses with AForge.net
Hey all i am trying to figure out why when i flip the image it uses a LOT
of RAM and CPU (its an quad core i7)
I use this code:
Dim filter As New RotateBilinear(180, True)
image = Filter.Apply(image)
If bIsToRecord Then
If writer Is Nothing Then
Dim [date] As DateTime = DateTime.Now
Dim fileName As [String] =
[String].Format("{0},{1}.avi",[date].Minute, [date].Second)
Try
OpenWriter(fileName, image.Width, image.Height)
Catch ex As Exception
If writer IsNot Nothing Then
writer.Dispose()
writer = Nothing
End If
End Try
End If
Try
If radioButton1.Checked Then
writer.AddFrame(image)
Else
mVideoFileWriter.WriteVideoFrame(image)
End If
Catch ex As Exception
System.Diagnostics.Trace.WriteLine(ex.ToString())
End Try
End If
That is WITHOUT flipping the images
WITH the flipping...
Each screenshot was for 30 seconds.
What could be causing this?

Hello I am a beginner to cocos2d and objective c. I am making a cocos2d
side scroller. I am using CCActions to make my background move. I want my
app to be universal. Right now I am making my app for the iPad, but I want
to make it compatible with all iPhone, iPod Touch, and iPad versions. I am
now learning that CCParallaxNode might make it easier to make the app
universal. Here is my code that I am using right now.
treeBackground = [CCSprite spriteWithFile:@"background.png"
rect:CGRectMake(0, 0, screenWidth * 2, screenHeight * 1.25)];
treeBackground.opacity = treeBackground.opacity - 75;
ccTexParams params = {GL_LINEAR, GL_LINEAR, GL_REPEAT, GL_REPEAT};

treeBackground.position = ccp(screenWidth, screenHeight/2);
[self addChild:treeBackground z:-5];

How to insert CSS code into a page if I can't insert it into head tag? Only inline mode?
How to insert CSS code into a page if I can't insert it into head tag?
Only inline mode?
I have to insert some CSS style into a Plain HTML module inside a CMS. The
problem is that I have no access to the template so I can't insert the CSS
into a .css style file.
I had thought that I could use the tag (that would enable me to insert the
CSS styles directly in the HTML) but reading online seems to me that I can
only insert it into the tag and I can't do it because I have not access to
the template code.
So my questions are:
Can I use the tag outside of the tag?
If not the only solution is to use inline CSS or can I try something else?
Tnx
Andrea

natbib: how to display partial authors in reference [duplicate]
This question already has an answer here:
natbib: how to display partial authors in reference 2 answers
I have asked this question on http://tex.stackexchange.com/, but nobody
answers me...
I am using natbib to manage my references, now I have a problem: my
reference list always displays all author names of an article:
Marcel H. Schulz, Daniel R. Zerbino, Martin Vingron, and Ewan Birney.
Oases: robust
de novo RNA-seq assembly across the dynamic range of expression levels.
Bioinformatics
(Oxford, England), 28(8):1086–1092, April 2012. 7, 9, 10, 40
I set the options to be:
\usepackage[round, sort, numbers]{natbib}
\bibliographystyle{Latex/Classes/PhDbiblio-url2}
\renewcommand{\bibname}{References}
\bibliography{9_backmatter/references}
And use cite{} to cite the references. I tried to used biblatex, but seems
it is not compatible with natbib:
\usepackage[maxnames=3]{biblatex}
I want to display at most 3 authors in full name, otherwise display as et
al. How to set it?
================
Edit: The file PhDbiblio-url2.bst can be found here:
https://bitbucket.org/dekz/thesis/src/3f8d8507cddc/Latex/Classes/PhDbiblio-url2.bst
It seems like the lines here define the display of authors:
INTEGERS { nameptr namesleft numnames }
FUNCTION {format.names}
{ 's :=
#1 'nameptr :=
s num.names$ 'numnames :=
numnames 'namesleft :=

real matrices can be made singular by switching EXACTLY $k$ entries with
ZERO ?
Update my ASP.NET MVC4 project templates?
Update my ASP.NET MVC4 project templates?
There are plenty of references around to ajax login form capability in the
asp.net mvc4 Internet Application project template, and also references to
related artifacts such as AjaxLogin.js and method ContextDependentView().
When I created a new project/solution from this template I don't see the
ajax login and I don't find these artifacts.
Is this because I don't have the latest version of the templates? If so
how do I refresh them?
I'm using VS2012 premium update 3.

I would like my mixing console app to be able to move multiple sliders
simultaneously when a user touches them with multiple fingers, just like
in real life.
I have already implemented my logic for a single pan gesture
(UIPanGestureRecognizer). How do I add multiple-touch functionality in
this case?

find depth of water
find depth of water
The bottom of an underground rectangular tank has an area of $12$ square
feet and the depth of the tank is $10$ feet. A liquid is pumped into the
empty tank at the constant rate of $30$ cubic feet per minute. After how
many minutes will the depth of the liquid in the tank be $8$ feet?
so first volume of rectangular tank is $12*10=120$ cubic,now if water is
pumped $30$ cubic feet per minute,then it takes $4$ minute to fill
tank,but what about $8$ depth,in this case volume would be $12*8=96$,does
it would be $96/30=3.2$ minute?

If $n$ order stats are iid from Uniform(0,1), why does dividing by the highest order stat give $n−1$ order stats iid from Uniform(0,1)?
If $n$ order stats are iid from Uniform(0,1), why does dividing by the
highest order stat give $n−1$ order stats iid from Uniform(0,1)?
As the title states:
If $P_{(1)}, ... ,P_{(n)}$ are order statistics of $n$ independent uniform
$(0,1)$ random variables, why are $P_{(1)}/P_{(n)} .....
P_{(n-1)}/P_{(n)}$ also order statistics of $n-1$ independent uniform
random variables on $(0,1)$, independent of $P_{(n)}$?
I'd prefer seeing an actual proof of this as I can't seem to locate one
anywhere. Any place I've found that mentions this theorem treats it as
"common knowledge" so-to-speak and doesn't give any theoretical
justification for the claim.
Any help is greatly appreciated!
