Maximum purchased toys time out
So yeah, I have a homework sort of question which I've solved but keeps
giving a timeout error on test cases and I can't figure out why.
You need to buy your nephew toys for his birthday. But you only have
limited money. However, you want to buy as many unique toys as you can for
your nephew. Write a function that will return the max number of unique
toys you can buy.
The arguments to the functions are the integer array costs that contains
the costs for each toy and the integer budget which is the max amount of
money you can spend.
Return the integer representing the max number of unique toys you can buy
Constraints
If N is the number of toys and K is the budget... 1<=N<=105 1<=K<=109
1<=price of any toy<=109
Sample Input
costs: {1, 12, 5, 111, 200, 1000, 10} budget: 50 Sample Return Value
4 Explanation
He can buy only 4 toys at most. These toys have the following prices:
1,12,5,10.
so this is what I wrote and it keeps giving a timeout error on 10
testcases. I can't figure out why
function maxPurchasedToys(costs, budget) {
var costsLess=[];
var removeFromArray=function(arr, value){
for(i in arr){
if(arr[i]==value){
arr.splice(i,1);
break;
}
}
return costsLess;
}
//First let's get a new array consisting only of costs that are equal
to or below the budget
costs.map(function(x){x<budget?costsLess.push(x):1;})
var sum=0;
costsLess.map(function(x){sum+=x;});//Get the sum of budget
while(sum>=budget){
var max=Math.max.apply( Math, costsLess );
costsLess=removeFromArray(costsLess,max);//Remove the biggest
element to ensure that the costs fall within budget
sum=0;
costsLess.map(function(x){sum+=x;});//Get the new sum of budget
}
return costsLess.length;
}
I tried the following cases: the original test case, [5000,2000,20,200],50
and a few more. All executed fine

Too much function call when painting using Direct2D, not efficient?
Too much function call when painting using Direct2D, not efficient?
The following code is from a example in Microsoft SDK, compared to GDI,
much more extra calls when painting. Because the function may be called
very frequently, it is not efficient, isn't it? And hr =
CreateDeviceResources(hWnd); uses something implicit, I don't think it is
a good design, because it is not clear, I can find the render target here.
BTW, if I want to past some code, do I have to indent every line with
spaces?

Open map location from Apple maps in my mapping app
Open map location from Apple maps in my mapping app
I'm developing an iOS mapping app. I would like to open a location from
the built-in maps app into my app. Ideally, my app would show up in the
Maps location sharing sheet along with Mail, Twitter, and Facebook. Is
this possible?
The best I've come up with is configuring my app as a routing app so that
Maps can send a routing request to my app, and using the destination as
the point being shared. There are a few problems with that, though. First,
my app doesn't do routing, so that's misleading to the user. Second, in my
opinion, there are too many steps for the user to get to the routing
options screen. Lastly, Apple might not approve an app that advertises
itself to the system as being a routing provider but doesn't actually do
any routing.
I've searched around quite a bit, but I haven't seen this question asked,
and I haven't found anything in Apple's documentation. Any suggestions?

Audio assets in Rails brings No route matches
I'm trying to use an audio file in rails. I created a folder audios under

put the file under folder app\public
Right now I'm getting
ActionController::RoutingError (No route matches [GET]

If I change the url from URL/audios/audio_file.wav to
URL/assets/audio_file.wav it works. How can i fix the problem? What is the
right way?

Begin search on first keypress in jQuery Chosen
I am using jQuery chosen as an alternative to normal html 'select'. I went
through its documentation and also its source files but couldn't achieve
what I wanted.
My database is very large(50K entries). I populate the select tab with
this data. When I click on this select it takes ages to drop down.
Here is the demo of my project.
Can I achieve the following in chosen.
-When I click select tag It should not show all the data initially.
-When I enter at least one charachter, results should get displayed.
If its not possible, is there an alternative to chosen which would solve
the issue? Thanks.

How to write a file inside Isolated Storage in C?
How to write a file inside Isolated Storage in C?
Let's say I open a file for writing in C.
fopen_s(&myFilePointer, "filename.bin", "wb");
If I debug my Windows Phone application from the Windows Phone Runtime
Component side, I see that there's a file somewhere that is written. At
least, there is no crash when writing.
But strangely, if I open a tool like IsoStoreSpy, I don't see any new file
in the application root folder. Does that means my created file doesn't
exist?
Should I specify a special directory when I want to write to the Isolated
Storage?
[Edit]
I'm also opening a file for reading the same way (no directory, no
isolated storage specific operation), and it works, no matter if I add it
as a resource or as a content. Then when the file is converted with a
codec to a destination, I can't see that file when exploring the phone.

Sanitize cell values with SuperCSV
Sanitize cell values with SuperCSV
What is the best way to sanitize fields from a csv in supercsv? For
example the First_Name column: trim the field, capitalize the first
letter, remove various characters (quotes, commas, asterisks etc). Is it
to write a custom CellProcessor like FmtName()? Maybe another one for
FmtEmail() that lowercases everything, removes certain invalid characters?

.Execute not available on a type safe Entity Framework query (Include & where)
.Execute not available on a type safe Entity Framework query (Include &
where)
I have a question regarding entity framework queries.
I have a query which is using the Extension methods provided by EF, so i
can use type safe includes and where clause. But as the Include is with a
lambda parameter it is an extension method on IQueryable that returns an
IQueryable in order to chain methods like Where. Include with a string
parameter is a method on ObjectQuery that returns an ObjectQuery. Execute
is a method on ObjectQuery, not IQueryable so it is not available when you
use IQueryable methods.
Is there a way to call .Execute but with IQueryable?
return
this.Storage.Customer.OfType<Preferred>()
.Include(b => b.Order)
.Where(cust => cust.Id == customerId && cust.CustomerType== (int)cusType)
.SingleOrDefault();
Thanks,

async each series does not return as expected
async each series does not return as expected
Im using async library, specifically the each method, but Im not getting
the expected result.
function instanceMethod (final_callback) {
obj = this;
async.parallel([
function (callback) {
getTopReplies (obj, function (err, result){
if (err) return callback(err);
if (result) {
obj.topReplies = result;
callback();
}
});
}, function (err){
if (err) return final_callback(err, false);
return final_callback (false, true);
});
This is the function Im calling from an async.parallel list of functions
function getTopReplies (obj, callback) {
mongoose.model('Post').find({replyTo: obj._id, draft: false})
.limit(3).sort('-createdAt')
.exec(function(err, tops){
if (err) return callback(err);
var result = [];
if (tops) {
async.eachSeries(tops, function(top, callback) {
result.push(top._id);
callback();
}, function (err){
if (err) return callback(err);
return callback(null, result);
});
}
});
}
theres a case where result should return two top posts id in the array but
it always returns 1 or if theres only 1 top reply to a post it returns
empty.
Is there anything wrong on my code?
Is the result array to be initiated somewhere else, like is it getting
reinitiated everytime, the each function is called or something?
Thank you!

Mongoid parsing and storing a date
Mongoid parsing and storing a date
I am receiving dates from a web form that come in format of "Thursday,
November 8th 8:20 p.m. (et)". I want to ensure that I store this in
MongoDB (I'm using Mongoid as my client driver) in an appropriate DateTime
field. Using Ruby or any available type library, what's the best way to
ensure when I'm parsing this date time that I store it in a way that won't
break the DateTime field Mongoid/MongoDB support?

Fixed 8 columns to 100% width in html table
Fixed 8 columns to 100% width in html table
I know this a simple question but still I'm a little bit confuse. This is
regarding my html table, i want to make my column 1 to column 8 (..) to be
fixed only to 100% width or 100% html width view, and the rest of the
column from column 9 and so forth, which is generated dynamically to be
scrollable horizontally. For example if i have 9 column table, when i load
my page the column 1 to column 8 would be visible and the 9th column can
only be seen when i scroll horizontally.
i already use tale-layout:fixed; but still it doesn't fit the column 1 to
column 8 100% of my page. If there were 10 column, its seems ok but if
there's alot of column like 15 thats the time my column 1 to column 8 to
become shrink and doesnt follow anymore my css width value.
any advice?

AS3 air app on ios image orientation wrong after saving to server
AS3 air app on ios image orientation wrong after saving to server
I have an app that is built in AS3/Air for iOS devices. In the app I allow
users to select images from the camera roll using the code from here
http://www.adobe.com/devnet/air/articles/uploading-images-media-promise.html
however with some images, when they are uploaded they are rotated
incorrectly.
I have read there are some EXIF data but I have no idea how to get this or
if this is the right data to get to set orientation.
Any help is appreciated.

How do I authenticate with the Play Purchase Status API using OAuth 2.0?
How do I authenticate with the Play Purchase Status API using OAuth 2.0?
I am using the Play Purchase Status API to help reconcile expiration of
in-app subscriptions. Specifically I am trying to match the
"validUntilTimestampMsec" up against recorded statuses that are managed
via IAB notifications. I am following the Authorization instructions here:
https://developers.google.com/android-publisher/authorization, but I am
wondering how to use the access and refresh tokens. After you get an
access and refresh token pair that looks like this:
{
"access_token" : "ya29.ZStBkRnGyZ2mUYOLgls7QVBxOg82XhBCFo8UIT5gM",
"token_type" : "Bearer",
"expires_in" : 3600,
"refresh_token" : "1/zaaHNytlC3SEBX7F2cfrHcqJEa3KoAHYeXES6nmho"
}
It shows how to access.
Once you have an access token, you can make calls to the API by appending
the token as a query parameter:
https://www.googleapis.com/androidpublisher/v1/...?access_token=...
I believe Play Purchase Status API needs to have v1.1 instead of v1, and
the rest of the first ellipsis is specific to what you are doing. The
second ellipsis setting the access_token is unclear to me whether it
should be the JSON containing the access/refresh pair or simply the access
token attribute of that JSON object. I am also curious as to whether this
pair stays persistent. On my back-end I want to pass a request to check a
subscription status. My PHP code simply builds the URL for the GET
request, and I attempt to use file_get_contents( $reqUrl ) where $reqUrl
is the url.
If I add the access_token URL parameter to the end of my URL query string,
should that work indefinitely, or should my code be generating new access
and refresh tokens each time it is about to call the API? Help in
answering these questions is much appreciated!

Use personal SSL Certificate created on my own?
Use personal SSL Certificate created on my own?
I'm new to SSL Certificates. I've seen some tutorials about creating
personal certificates but I didn't go far reading.
It seems that I can create a personal SSL Certificate and use it on my
website, but the question is:
Will it do its job nicely?
Will the connection with my customers will be encrypted?
Is it possible to create a personal SSL Extended Validation certificate on
my own, or do I need a certificate authority?
My point is I don't need insurance; I just want to add another layer of
protection and safety for my customers. They wont actually buy on my page,
but from paypal, but a SSL certtificate will increase they trust to the
site. I don't care if some company will take responsibility and appear on
my certificate info.

Deleting GDI objects does not decrease their number
Deleting GDI objects does not decrease their number
When I look in the Task Manager on the number of GDI objects for my
process, then I see that not every call of function DeleteObject() for a
GDI object causes decrementing this number, and the function call does not
return FALSE (as it should if the object deletion was unsuccessful). I'm
using plain Windows API GDI functions without additional libraries and
wrappers such as MFC. Why such situation can happen and does it mean GDI
resource leakage?

show text in select box in jquery
show text in select box in jquery
I have a select box and according the selected value I want to show the
value in next selected box. My code is like:
$('#category').change(function(){
var cat_val = $('#category option:selected').text();
if(cat_val == 'Online'){
$('#workshop-row').hide();
$('#bu_id').val(22);
}else{
$('#workshop-row').show();
}
});
By doing $('#bu_id').val(22); I can get the value. But I need to set the
text not val() like
$('#bu_id option:selected').text("Online");
That means if I select Online from the first select box then in the 2nd
select box, the value whose text is Online will be selected.
Please guide me. Thanks in advance.

How to convert numbers into strings in python? 1 -> 'one'
How to convert numbers into strings in python? 1 -> 'one'
If i want a program where I let the user input a number (e.g. 1, 13, 4354)
how can i get it to print (one, thirteen, four three five four) does that
make sense? if it's two digit, print it as though it's joined (thirty-one)
but if it's more than 2 just print them sepretly, one the same line joined
with a space, I tried to do this with a dictionary, and I think it's
possible, but i can't figure out how to do it?
l = input('Enter the number: ')
if len(l) > 2:
nums = {'1':'one',
'2':'two',
'3':'three',
'4':'four',
'5':'five',
'6':'six',
'7':'seven',
'8':'eight',
'9':'nine'}
elif len(l) == 2:
tens = {'1}'how
for k, v in nums.items():
print(k, v)
This is obviously a wrong code, but I would like the finished result to
look something like this? thanks in advance!

Renderscript compilation doesn't generate files in 'gen' dir
Renderscript compilation doesn't generate files in 'gen' dir
I have a renderscript in my android project which compiles properly. The
.bc file generated looks correct and there's also the corresponding .class
file that gets generated (ScriptC_...class). However, I can't seem to find
the 'gen' directory.
How do I go about fixing this? I'm on AndroidStudio 0.2.5, API 17. Here's
the project structure:
<root>
.idea
build
<projectname>
classes
ScriptC_blah.class

main
gen
java
...moredirs...
<sourcecode>

Parse a list of integers using boomerang
Parse a list of integers using boomerang
I'm trying to parse URLs of the form
/123/456/789
using the following code:
{-# LANGUAGE OverloadedStrings, TemplateHaskell, TypeOperators #-}
import Prelude hiding ((.), id)
import Control.Category ((.), id)
import Text.Boomerang.TH (derivePrinterParsers)
import Web.Routes.Boomerang
data Indices = Indices [Integer]
$(derivePrinterParsers ''Indices)
sitemap :: Router () (Sitemap :- ())
sitemap = rIndices . rList (integer . eos)
Unfortunately, trying to run this parser with
> parse sitemap ["0", "1"]
causes an infinite loop.
Is there any simple way to parse a list of slash-separated integers?

Use UConverter class on PHP 5.3
Use UConverter class on PHP 5.3
I have PHP 5.3.1 installed on my system (Ubuntu 12) with intl extension
installed with apt-get install php5-intl. While I'm able to use such intl
classes as Collator and Locale, I can't seem to use other classes like
UConverter:
echo UConverter::UTF16;
outputs
Fatal error: Class 'UConverter' not found in ...
Do I need to upgrade intl extension to the latest version? Would I
preferably be able to do so while keeping PHP at the current version?

factory method pattern in java
factory method pattern in java
Is it a good practice to have objects specific to some implementation as
member variables in a factory class ? For e.g., in the code below, s1 and
s2 are required for constructing OneChannel and secondChannel objects
respectively. Is it a good practice to declare these as member variables
inside the factory ? If not, what can e the other alternative.
public class CommunicationChannelFactoryImpl {
@Autowired
SomeClass s1;
@Autowired
SomeOtherClass s2;
public CommunicationChannel getCommunicationChannel(String channel,
Map<String, String> channelProperties) {
if(channel.equals("ONE") {
return new OneChannel(s1);
}
if(channel.equals("TWO") {
return new SecondChannel(s2);
}
}
}
Please note that s1 ad s2 are singleton objects

Enabling User Manager did not work.
Tried old Versions, did not work.
Anyone faced same issues?

Looking for a good library of Tasker scripts/recipes
Looking for a good library of Tasker scripts/recipes
I am looking for a library of Tasker scripts/recipes.
By "Good", I mean the following features are a must:
Sizable (say, 1000 recipes total at least)
Fully categorized recipes
Fully searchable (don't care if internally or via Google)
Preferably, has user based voting/ratings, and a user base of 1000+ people
who rate.
I don't really care what format the recipes/scripts are (e.g something
that is code readable by Tasker, or instructions readable by a person, are
both fine).
What I am NOT looking for:
* Some blog article with 'top 10 Tasker recipes
* Actual tasker scripts posted as answers

Get mysql result in javascript global array for further searching through list
Get mysql result in javascript global array for further searching through
list
I need to have a MySQL table result in JS array so that i can search
through the names when typed in a text box. I mean, lets say i have a
table with some names, now when the page is requested, it should populate
a div with the list of the names from MYSQL, the div needs to have an
input box in which when initials are typed, the list below should find the
names matching the keywords kind of like search.
For this, i think i need to store the mysql result in a JS array so that
on the onkeyup and onkeypress event of the text box, it should search for
the matching results from the array items and populate the list with only
those items.
I know, i'll have to make an ajax request on document.ready to fetch the
results from database but then have no idea, how to store it in an array
and then search through that on the text box events.

How long does Linux (by default) cache information about files in the disk?
How long does Linux (by default) cache information about files in the disk?
I'm testing whether some changes I made to some code are effective or not.
For this, I need to know how the file system cache normally works. I'm
assuming the default is what we're getting, since we probably haven't
tweaked anything interesting regarding this.
Essentially, if from my code I ask "does this file exist?", the answer
comes back in "x" milliseconds. If I ask again a few minutes later, the
answer comes back much, much quicker, so I'm guessing there's some caching
going on there.
How long should I wait if I want to test again, with the cache flushed, so
it'll take "long" again? (I want to see if I fixed a performance problem
in my web app, but I can only know that it's fixed if the info about files
existence isn't cached, because if it is, it does run fast)
I know this is not the most eloquent question, and the answer is probably
"it depends", I'm asking for a sane default. In other words, if I test
again in 3 hours, or 6, or whatever, can I count on it not being cached?
As far as I can tell... This is a Ubuntu server, kernel version:
3.9.3-x86-linode52, Ubuntu version: Ubuntu 12.04.3 LTS, hosted on Linode.
The file system is ext3
Thank you!

Javamail - sending mail with login different from email

Got a problem with my email method, code below:
public static void send( final String username, final String password,
String recipientEmail, String ccEmail, String title, String message,
String from, String host, String port )
throws AddressException, MessagingException
{
try
{
Session session;
Properties props = System.getProperties();
props.setProperty( "mail.smtps.host", host );
props.setProperty( "mail.smtp.port", port );
props.setProperty( "mail.mime.charset", "utf8" );
session = Session.getInstance( props, null );
// session.setDebug( true );
String uFrom = from;
// setting encoding properly
/*
* try { uFrom = new String( from.getBytes( "UTF-8" ),
"ISO-8859-1" ); } catch (
* UnsupportedEncodingException e ) { // logi ! }
*/
// -- Create a new message --
final MimeMessage msg = new MimeMessage( session );
// -- Set the FROM and TO fields --
msg.setFrom( new InternetAddress( username ) );
msg.setRecipients( Message.RecipientType.TO,
InternetAddress.parse( recipientEmail, false ) );
if ( ccEmail.length() > 0 )
{
msg.setRecipients( Message.RecipientType.CC,

t.connect( host, username, password );
t.sendMessage( msg, msg.getAllRecipients() );
t.close();
}
catch ( Exception e )
{
e.printStackTrace();
}
}
And the problem is that my client is using mail where login is eg.
'superinfo' and the real mail is 'info@domain.com'.
When system is using this mail to send a message i get:

change device orientation compatible for ios6 and ios5
change device orientation compatible for ios6 and ios5
I NEED: rotate device programmatically from portrait to landscape
compatible for iOS6 and iOS5. THE PROBLEM: I cannot use [UIDevice
setOrientation] function on ios6.
WHAT I HAVE: the code for iOS6:
- (BOOL) shouldAutorotate
{
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
the code for iOS5:
-
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
So, I need write the code that rotate on iOS5:
-(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated];
// [[UIDevice currentDevice] setOrientation] - I cannot use it
// ???
}

How to handle unnecessary whitespace leading to widows/orphans?
How to handle unnecessary whitespace leading to widows/orphans?
I'm working on my paper using TexMaker and this is what's happening:
I'm getting unnecessary whitespace before paragraph 'B'. As a result of
the unnecessary whitespace I have a widow/orphan of an equation reference
at the start of the next page. I'm pretty much at my wits end wondering
what is the problem here.
Here is the LaTeX code for the paragraph and the corresponding equation
section:
\subsection{Computing Tester/Developer Payoffs}
\label{subsec:payoffs}
In a security game defenders may employ mixed strategies i.e., selecting a
particular action with some probability as opposed to a deterministic
choice. This distribution decreases predictability of choice of
actions that may be exploited by an adversary. For our testing game we
refer to the set of distributions as a \textit{coverage vector}, $C$
that gives the probability, $c_t$, that a particular test suite $t$,
covering a particular requirement will be executed. We then compute
the expected payoffs for the testers and developers as shown in
Equations~\eqref{eqn:tC-EU} through ~\eqref{eqn:attack-set}
\begin{IEEEeqnarray}{c}
\label{eqn:tC-EU} U_\tester(t,C) = c_t \cdot \testercovered +
(1-c_t)\cdot \testeruncovered \\
\label{eqn:CA-EU} U_\tester(C,\reqvector) = \sum_{t \in T} \attackprob
\cdot (c_t \cdot \testercovered + (1-c_t)\cdot \testeruncovered) \\
\label{eqn:attack-set} \Gamma (C) = \{t:U_\dev(t,C) \geq
U_\dev(t',C)\, \forall t' \in T\}
\end{IEEEeqnarray}
%...remaining text
There is nothing out of the ordinary in the code IMO. Why does this happen
and how should I fix it (whitespace + widow/orphan)? This abruptly started
happening after editing the paper. I'm guessing it's something to do with
auto layout of LaTeX and not really something in the code.
PS: If it's of any use, here's the code for the table in the screenshot
above:

set those values to column number 13 which does not have radio box when i
saw source code from browser i see id e.g somethingId:0:j_xxx,
somethingId:1:j_xxx so on.. i can not understand this.. please HELP!!

Bootstrap Multiselect Integration with WTForms
Bootstrap Multiselect Integration with WTForms
I'm new to WTForms and was wondering how to integrate a bootstrap styled
multiselect like this one
http://davidstutz.github.io/bootstrap-multiselect/ into WTForms.
I know I can write the HTML directly to create the multiselect dropdown
form but I'd rather work with WTForm objects to keep my forms consistent.
Is there a simple way to convert the WTForms SelectMultipleField class
into a dropdown multiselect box? Or is something more sophisticated
needed?
Thanks!

Oozie issue with ssh action performing on the Edge node of the cluster
Oozie issue with ssh action performing on the Edge node of the cluster
'm trying to schedule a oozie job through ssh action on the edge node. As
my bash scripts for each of the phases in the process flow. Here, i'm
facing lot of issues like ilts not at all allowing to start the job. I
have read in different blogs stating that if we have to setup
password-less ssh so that we can eliminate this type of issue, but its not
safe to do because the cluster will become vulnerable!! Moreover if this
type of passwordless ssh setup can be done on devclusters but when it
comes to production it may give the same errors (which is kerberized)
there we may not be able to generate passwordless -ssh. Is there any other
method to resolve this type of issue or please suggest what can be done to
trigger a job at the edge node if the files are in HDFS

'm trying to schedule a oozie job through ssh action on the edge node. As
my bash scripts for each of the phases in the process flow. Here, i'm
facing lot of issues like ilts not at all allowing to start the job. I
have read in different blogs stating that if we have to setup
password-less ssh so that we can eliminate this type of issue, but its not
safe to do because the cluster will become vulnerable!! Moreover if this
type of passwordless ssh setup can be done on devclusters but when it
comes to production it may give the same errors (which is kerberized)
there we may not be able to generate passwordless -ssh. Is there any other
method to resolve this type of issue or please suggest what can be done to
trigger a job at the edge node if the files are in HDFS
below i have placed one of the error lod msg

Do you use capitalization in titles?
Do you use capitalization in titles?
This is a stylistic question. Or maybe about grammar... I don't know. When
and why do you use uppercase first letters?
I am German and in German documents, it is clear, to write all words like
always even when appearing in a title. The first letter of a title is
always capitalized.
In English, I understand, there are different rules. But are there
differences between UK- and US-English? Should that be localized to where
the thesis is written?
Until now, I have the feeling, that capitalizing main titles is done
everywhere (in English area)
This is a Book Title
In the US, chapter titles follow this rule
This is an US Chapter Title
but not in the UK
This is an UK chapter title
Are there any rules around? What is your experience?
Would there be a possibility to switch all the Table of
SomethingCapitalized to Table of something-not-capitalized?

How to interchange data between Java Program and C++ Program
How to interchange data between Java Program and C++ Program
I constructed a java program using netbeans IDE that has ability to
connect with a respective DLL; I want to connect and interchange data
between my java program(.jar) and VSC++ program(.exe) through DLLs.JNI
uses single Dll to invoke C/C++ function in native manner,In order to
increase the efficiency I tried to connect and interchange primitive data
types between Java program and C++ program using that DLL(JNI
implemented).
Unfortunately C++ program cannot obtain data values that has been changed
by Java Program.Fot example - If I declare a global int variable in
DLL,java program can catch that int variable and can update it but If I
run my C++ program(exe) loading same DLL simultaneously it cannot receive
the updated value of that int variable declared in the DLL.
Therefore I need a solution to share/Interchange at least primitive data
and their respective values between a JAVA and C++ Program using JNI (in
spite of date transferring through Sockets).JAVA TO C/C++ & C/C++ to JAVA
using DLLs.
PLEASE HELP ME!! THANK YOU

Mute jQuery Migrate in Ruby on Rails test environment
Mute jQuery Migrate in Ruby on Rails test environment
Our rails project receives a lot of JQMIGRATE message when running tests, eg:
JQMIGRATE: jQuery.fn.attr(selected) may use property instead of attribute
JQMIGRATE: jQuery.browser is deprecated
Obviously it would be good to fix them, but they seem to be due to other
gems anyway.
I've seen reference to jQuery.migrateMute = true, but not sure where to
include it, and more importantly, would like to mute in test environment
but not development. What's the best way?

R Base Graphic: Annotate with logical symbols (and/or)
I would like to add the logical symbols and (È) and or (É) to a base
graph in R.
I figured that the way to go will probably be using an expression, but I
can't figure out how, as their unicode codes \u2227 and \u2228 are not
working. Perhaps because I am on windows (win 7, 64 bit).
What I have:
plot(1, 1, pch = "")
text(1, 1.2, expression(paste("low ", italic(P), "(", italic(p), " and ",
italic(q), "), -1 SD")), cex = 1.2)
text(1, 0.8, expression(paste("low ", italic(P), "(\u00ac", italic(p), "
or ", italic(q), "), -1 SD")), cex = 1.2)
I would like to replace the literal and and or with their symbol counterpart.

Using a function query from Solr
Using a function query from Solr
I'm trying to calculate the tf*idf of a term in my index.
Following Yonik's post from
http://yonik.com/posts/solr-relevancy-function-queries/ I tried
http://localhost:8080/solr/select/?fl=score,id&defType=func&q=mul(tf(texto_completo,bug),idf(texto,bug))
(where texto_completo is the field, and 'bug' is the term) without much
success. The response was:
error 400: The request sent by the client was syntactically incorrect (null).
I went ahead and looked at this answer /a/13477887 so I tried to do a
simpler function query:
http://localhost:8080/solr/select/?q={!func}docFreq(texto_completo,bug)
And yet, I got the same error.
What is my syntax lacking to work properly?

programs to push files to remote copmuter
programs to push files to remote copmuter
Objective: Have a folder on my desktop, drop files into this folder, this
begins a transfer from my computer to a remote computer. if the transfer
is interrupted the transfer should resume from that point.
I have no need of "cloud storage", my objective is only to transfer the
files. I realize that a P2P transfer requires both machines to be online
at the same time, but this is not a problem for my use.
I know command line solutions exist, but I'd prefer a drag and drop
interface.
I'd prefer a solution that includes end to end encryption.
Use case:
I often wish to send large video files from my laptop to my home computer
while traveling.
In my perfect solution, I'd simply drop those files into my "transfer to
home computer" folder. This would begin the transfer. I could shutdown my
laptop at any point (temporarily halting the transfer) and upon rebooting
my latop, the transfer would resume.
Ideas: dropbox ssh teamviewer / vnc / rdp wuala
While teamviewer does contain a file transfer mechanism, but the
teamviewer window must remain open for the duration if the transfer is to
succeed. Also, this method is not robust, no resume is possible after a
disconnection.
Dropbox is not encrypted, and suffers from a storage cap.
ssh is commandline based, and I've found no gui interfaces that will
achieve my objective.
wuala is encrypted, but I can't tell from their info if I can arrange so
that the download begins automatically on my home computer.

Javascript result into httpcontext.current
Javascript result into httpcontext.current
I have some javascript code in an mvc4 project that returns a string. I
want this to be passed back on every request to the server. I wanted to
avoid the overhead of modifying every controller and page to pass this
thing around and just unify it to every request, can be both post and get.
I didn't know if there was some way to put the javascript result into
httpcontext.current.
I cannot put this in session or viewdata as this is a key on how to access
the session variables.

Given the E[X] of a discrete uniform random variable...
Given the E[X] of a discrete uniform random variable...
The expected value of a discrete uniform random variable U is 6.5.
a) Find P(U=3).
b) Find the variance of U.
Discrete uniform variables have the following characteristics:
The mean (expected value) is (a+b)/2.
The variance is ((n^2) - 1) / 12.
n = b-a+1.
pmf = 1/n.
My work:
So, I need to find the PMF where U=3. To do that I need to find n. Since I
only have the mean, it follows 6.5 = (a+b)/2. But, I know neither a or b,
so how do I solve? Should my final answer have a variable in it? Is there
another way to figure this out?

Why can I call a subclass method with a superclass pointer in Objective-C?
Why can I call a subclass method with a superclass pointer in Objective-C?
I have two classes, NSMom and NSSon. NSMom is NSSon's super class.
NSMom *mom = [[NSSon alloc] init];
is valid as long as I call NSMom's methods, right?
But how come that mom pointer can call one of NSSon's methods (which is
defined as an additional method in the subclass)?

Sass not compiling in textmate
I'm trying to use SASS for the first time with textmate. I seem to have
installed it correctly by following the instructions on the git page -
https://github.com/MarioRicalde/SCSS.tmbundle but I can't find any
information on how I can now use it.
When I make a .sass file the new Sass syntax is highlighted but when I
save it is not compiled. Am I missing something?

information on how I can now use it.
When I make a .sass file the new Sass syntax is highlighted but when I
save it is not compiled. Am I missing something?
Does anybody know the reason why QuotationEvaluator is so slow?
Does anybody know the reason why QuotationEvaluator is so slow?
It's common knowledge in the F# community that the PowerPack's quotation
compiling facility produces very slow code, so slow in fact that it
performs even worse than naive interpretation. I've been looking into the
reasons for this, but I haven't been able to find a convincing answer so
far. There have been claims that this happens either because of
inefficient representation of things like pattern matches in quotations or
because of an inherent inefficient with Expression Trees used by the
library. I'd like to illustrate why I think neither is true with a simple
example:
#r "FSharp.Powerpack.Linq.dll"
open System
open System.Linq.Expressions
open Microsoft.FSharp.Quotations.Patterns
let powerpack = Microsoft.FSharp.Linq.QuotationEvaluator.Compile <@ 1 + 1 @>
// explicitly rewrite above quotation with expression trees
let expressionTree =
let (Call(_,addM,_)) = <@ 1 + 1 @>
let constExpr (x : 'T) = Expression.Constant(box x, typeof)
let eval = Expression.Call(addM, constExpr 1, constExpr 1)
let lambda = Expression.Lambda>(eval)
lambda.Compile()
#time
// QuotationEvaluator ~ 2.5 secs
for i in 1 .. 1000000 do
powerpack () |> ignore
// native evaluation ~ 1 msec
for i in 1 .. 1000000 do
(fun () -> 1 + 1) () |> ignore
// naive expression tree ~ 19 msec
for i in 1 .. 1000000 do
expressionTree.Invoke () |> ignore
Something clearly goes wrong here. The question is, what?

Error calling activity with receiver
Error calling activity with receiver
I have a Receiver that gets SMS but I try to call an Activity with an
Intent as shown below: public class Receiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent arg1) {
Bundle mBundle = arg1.getExtras();
SmsMessage[] messages = null;
String strMessage = "";
if (mBundle != null)
{
Object[] duster = (Object[]) mBundle.get("pdus");
messages = new SmsMessage[duster.length];
for (int k = 0; k < messages.length; k++)
{
messages[k] = SmsMessage.createFromPdu((byte[])duster[k]);
strMessage += messages[k].getMessageBody().toString();
}
//Toast.makeText(arg0, "Hi", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(context, Popups.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("message", "My popup number " + 1);
context.startActivity(intent);
}
}
}
But when I try to do this, I get this error. Anyone know what I am doing
wrong? I have the Permissions RECEIVE_SMS and PROCESS_OUTGOING_CALLS

Repeat colnames in R
Repeat colnames in R
I'm trying to figure out how to repeat a set of column names. Sometimes
I'll have 1 set of columns to name and some other times I'll have 4 sets
of columns to names. For example:
1 set of column names:
r a
2 set of column names:
r a r a
I've tried using this for loop:
for(cnt in 1 numSetCol){
colnames(data[,cnt]) <- "r"
colnames(data[,cnt+1]) <- "a"
cnt <- cnt + 2
}
I get the error: attempt to set colnames on object with less than two
dimensions.
Any help on how to do this would be great.
Thanks!

What is the best approach for Android Service and data communication
What is the best approach for Android Service and data communication
I am looking for the best approach to share data between a service and 2
different clients (an app and a widget). Currently my application kicks
off a thread that downloads a large amount of data every 15 seconds or so
in the background, stuffs them into an object graph, which is then
consumed by the main app on a configurable time interval. This works for
the primary app but isn't sufficient for the widget that I want to develop
as well, because the object graph will be out of process (and the approach
is kind of messy IMO).
So I am looking to extract the data retrieval part into a service (or if
there is a better suggestion, something else). My question is, what is the
best way to communicate the data received from this service with the
clients? Or would you not use a service and instead use something else?
Because of the overhead on the client, I want the service to notify the
clients when data is ready as opposed to the client continuously polling
the service.....if possible...of course.
I have looked at broadcasting the intent (both app and widget would
receive) but I think I have to serialize the entire object graph and then
inflate it in the client in order to do that. Is that correct? I am
concerned with the speed at which I can accomplish the re-inflate client
side.
Is there a better way to ship the data back to the clients? I would prefer
to ship the objects if that is possible and not serialize...but if that is
the best way, then I will do it.
Any help is greatly appreciated!
