Mike asks Billy to help him run his lemonade stand. He'll either pay him
2/5 of ½ of the stand's profits, or 1/3 of ¾ of the stand's profits. Which
should Billy choose to maximize the amount he will earn, and by what
amount will his earnings be increased?
Billy should choose 1/3 of ¾; he'll earn 1/15 more.
Billy should choose 1/3 of ¾; he'll earn 1/20 more.
Billy should choose 2/5 of ½; he'll earn 1/15 more.
Billy should choose 2/5 of ½; he'll earn 1/20 more.
It doesn't matter; either way, Billy will earn exactly the same amount.

Grab, move and drop control in Form by mouse
Hello I have found this code that might help me with following issue, I'm
trying to make drag, drop and move label in my Form by mouse.
private Point MouseDownLocation;
private void MyControl_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
MouseDownLocation = e.Location;
}
}
private void MyControl_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == System.Windows.Forms.MouseButtons.Left)
{
this.Left = e.X + this.Left - MouseDownLocation.X;
this.Top = e.Y + this.Top - MouseDownLocation.Y;
}
}
But when I assing mousemove and mousedown as events to label and i try to
grab the label and move with mouse it moves with the whole Form.
May I ask where is should the code be improved?
Thank you for your time.

FORCE INDEX mySQL ...where do I put it?
FORCE INDEX mySQL ...where do I put it?
I have the following mySQL query that works perfectly fine. Except that I
need to add a "FORCE INDEX" and I'm unsure on where I have to do this. I
tried just about every location and always receive a mySQL error. What am
I doing wrong?
Here is the original query:
$sql_select_recent_items = $db->query("SELECT * FROM (SELECT owner_id,
product_id, start_time, price, currency, name, closed, active, approved,
deleted, creation_in_progress FROM db_products ORDER BY start_time DESC)
as resultstable
WHERE resultstable.closed=0 AND resultstable.active=1 AND
resultstable.approved=1 AND resultstable.deleted=0 AND
resultstable.creation_in_progress=0
GROUP BY resultstable.owner_id
ORDER BY start_time DESC");
The query is constructed this way so that I can do the "ORDER BY" before
the "GROUP BY", in case you're wondering.
What I need to add is:
FORCE INDEX (products_start_time)
I tried it just about everywhere without success, which leads me to
believe that there's something more complex that I'm missing?

need help using div and iframe
need help using div and iframe
i have created a little website (which will probably stay offline) to make
some things easier; i created a hotbar with links so i can navigate to
important sites more easily problem is: to iframe google into the webpage
i had to use a proxy (i used hidemyass) because google blocks the use of
iframes, but because the proxy site has a huuuugeee banner on top of every
page you open trough it i moved the content inside of the iframe using
margin top in CSS so the banner is still there but you can't see it but
now whenever i open any other website in the same iframe without any
banners it will hide part of the website and i don't want this so how do i
make it hide the banner on top of the proxy page and still fully display
any other page? i tried to give the div and iframe 2 names so that i could
make 2 CSS statements but this doesn't work. here's the code thanks, jordy

jQuery Countdown installed. Having trouble displaying multiple countdowns...
Please review my Sample Fiddle...
I have a jQuery Countdown timer installed. It's nested inside an accordion

There's supposed to be a different timer under each accordion. It only
seems to work when I have it under one accordion. Once I placed the code
under multiple accordions, it only accepts the data from the last timer.
I'm trying to get one under each. Can you push me in the right direction?

HttpSession remains after server restart
HttpSession remains after server restart
I'm learning Spring. Doing the login/logout functionality. This is what my
controller looks like:
@RequestMapping(value="/successfulLoginAuth", method=RequestMethod.GET)
public ModelAndView postHttpLogin(HttpSession session, Authentication
authInfo)
{
ModelAndView mav = new ModelAndView();
mav.setViewName("redirect:/index.html");
session.setAttribute("authInfo", authInfo);
return mav;
}
The log in is performed via Spring Security using a dao service which I
have implemented. That works fine.
This is the content of index.jsp:
<%
HttpSession session1 = request.getSession(false);
Authentication authInfo;
if( (session1 != null) &&
( (authInfo = (Authentication)session1.getAttribute("authInfo"))
!= null)
)
{
out.print(" yo " + authInfo.getName() + " " +
authInfo.getAuthorities().iterator().next().getAuthority());
}
else
{
%>
<a href="${pageContext.request.contextPath}/registration">New? Sign
Up!</a><br/>
<a href="${pageContext.request.contextPath}/login">Existing? Sign
In!</a><br/>
<%} %>
When i log in, and restart the server, I'm still logged in. Shouldn't the
session information be lost after a server restart? If i restart the
browser, it works as it should (ie the session info is lost).
This is my Spring Security configuration:
<http auto-config="true" use-expressions="true">
<intercept-url pattern="/" access="permitAll" />
<intercept-url pattern="/logout" access="permitAll" />
<intercept-url pattern="/accessdenied" access="permitAll" />

c# check if library/namespace/class exists (at compile time)
c# check if library/namespace/class exists (at compile time)
I've written some code in c# that uses a library, but I want to share it
and want it to work regardless of whether that library exists, basically I
want to check in my code whether the library exists, and if it doesn't, I
use alternate code to do what the library was supposed to do.
So how would you do that?
I thought maybe I could use Preprocessor Directives, but to be honest I
have little experience with these and can't seem to find how to this.

Rapid Xml parse error if you don't use strlen (or similar function) on a download?
Rapid Xml parse error if you don't use strlen (or similar function) on a
download?
Hello fellow code monkeys,
I've run into the oddest problem I've ever seen today. I'm using a
codebase that uses rapidXml (unmodified to my knowledge). (C++ code base)
If I download a file (using proprietary code but that we've used for many
years) leaving it in the buffer, and then parse it with rapid xml, I get
back a parse error at the base tag. I've walked through the code and
satisfied myself to seeing that something is messed up.
If I download the file in Chrome, I can open the file, and validate the
XML easily. I can also download the file, open it with my program using
basic file commands and parse it into the rapidXML that way, and that
works.
If I open the file, and download the file at the same time with my program
the files strncmp perfectly. There is a trailing null on the file IO, but
adding that to download doesn't fix anything.
But this is where the query is.
If I strncmp and then parse the download buffer with rapid XML, the parse
completes correctly. If I do the same but instead run strlen, and then
parse the buffer, it also completes correctly.
It's not a time issue, as the download phase is finished, and I can open
the file and parse that, after the download, but before parsing the
downloaded buffer, and I'll still parse the download buffer incorrectly.
So the question is, I know strlen is a non destructive operation, it
actually shouldn't even change any of the data. It does return back the
shorter file size (by a byte) as expected. However is there any idea what
strlen (or strncmp) can be doing that causes the system to correctly parse
the buffer correctly?
Some factoids if necessary, the files are currently 141k, the download is
off of a storage cloud that's reliable, and my code does not operate until
the download is finished, and that code has stopped running, strlen and
strncmp is the standard variants, non destructive operations.

xcode 5 documentation: where is the table of contents for the entire
documentation?
There is a table of contents on the right, but it is internal to the
current page.
In the previous version of the documentation you could view the main
titles. See the screenshots in this post: Xcode organizer documentation,
show Table of Contents
Is there a way to show the TOC for the entire documentation installed?
Also is there a way to move the page internal TOC to the left?
Thanks!

Can and cannot see pictures in jsp project depending on port
I inherited a project from a previous programmer, when I run the code on
the server, there are a list of images that are shown and not shown.
I checked they're path and they have:
http://localhost:8888/images/small/classified/1135/...
in common.
The images for
http://localhost:8080/...
are showing fine, port 8888 doesn't show anything.
Could you please advise me what to check?

Adding a map function to a vector in C++11
Adding a map function to a vector in C++11
I have a custom vector class that for all intents and purposes acts just
like std::vector. I want to add a simple map function:
template <class T> class Vector
{
public:
template<class mapFunction> Vector<typename mapFunction::result_type>
map(mapFunction function)
{
Vector<mapFunction::result_type> result(_Length);
for(UINT i = 0; i < _Length; i++)
{
result[i] = function(_Data[i]);
}
return result;
}
...
}
Usage:
Vector<int> v(5);
for(int i = 0; i < 5; i++) v[i] = i;
auto mappedVector = v.map(function<double(int)>([](int a) { return a *
2.0; }));
This works but I'm trying to avoid the need for the cast from a lambda
expression to std::function. Ideally it would just be v.map([](int a) {
return a * 2.0; })); I realize that I could probably write a
"make_function" similar to "make_pair" to avoid the need for template
parameters, but you'd still need to cast all your lambdas.
I cast it to a std::function because I don't know how to extract the
return type from a raw lambda type; hence I'm using
std::function::result_type.
I thought the following would work, but it doesn't -- the compiler just
complains that it cannot deduce the template argument for "returnType":
template<class mapFunction, class returnType> Vector<returnType>
Map2(mapFunction function)
{
Vector<returnType> result(_Length);
for(UINT i = 0; i < _Length; i++)
{
result[i] = function(_Data[i]);
}
return result;
}
I realize that std::transform does this (I could easily replace the body
of map with a call to std::transform), but my problem is really with the
right way to specify the template parameters.

How do I place the elements of a list into the middle of another list? A one dimensional battleship game. (Python)
How do I place the elements of a list into the middle of another list? A
one dimensional battleship game. (Python)
So I'm creating this simple little battleship program. I'm getting a
little frustrated at the aspect of a player placing their boats. What I'd
like is for the function ship_place() to take a boat as a parameter, ask
for the index of the array the player would like to place the boat, and
then place the boat in the ocean starting at the specified index. I want
the contents of the boat (which is a list) to be "exported" to the ocean
(which is also a list).
I created this function and it's been giving me two errors. The first is
that for some reason it's placing the entire boat array into the specified
index. The second is that the list taken_spots1 is not receiving all of
the taken spots it should be.
P.S. I originally had for loops within the function but was getting the
same error, so I tried while loops to see if anything would change.
Nothing did.
ocean = ['O']*100
taken_spots1 = []
boat1 = ['<','>'],
boat2 = ['<','=','>'],
boat3 = ['<','::','>'],
boat4 = ['<','@','@','>'], #cannons
boat5 = ['<','G','U','N','>']
ship_yard = [boat1,boat2,boat3,boat4,boat5]
def ship_place(boat):
spot = ""
while spot == "":
spot = input("Place a boat: ")
spot = eval(spot)
if spot in taken_spots1:
spot = ""
print("That spot's already taken, dummy")
else:
j=0
while j < len(boat):
taken_spots1.append(spot + j)
j += 1
i = 0
while i < len(boat):
ocean[spot - 1 + i] = boat[i]
i += 1
for i in range(5):
ship_place(ship_yard[i])
print(ocean)
print(taken_spots1)

Hoping someone can help. I'm able to compile with no error, I'm not
finding any syntax errors but when I run this, it crashes. Debug segfaults

Question: You found an exciting summer job for five weeks. It pays, say,
$15.50 per hour. Suppose that the total tax you pay on your summer job
income is 14%. After paying the taxes you spend 10 % of your net income to
buy new clothes and other accessories for the next school year and 1% to
buy school supplies. After buying clothes and school supplies, you use 25%
of the remaining money to buy savings bonds. For each dollar you spend to
buy savings bonds, your parents spend $0.50 to buy additional savings
bonds for you. Write a program that prompts the user to enter the pay rate
for an hour and the number of hours you worked each week. The program then
outputs the following: a. Your income before and after taxes from your
summer job. b. The money you spend on clothes and other accessories. c.
The money you spend on school supplies. d. The money you spend to buy
savings bonds. e. The money your parents spend to buy additional savings
bonds for you.

Links don't work on iPad for the dragend JS framework
Links don't work on iPad for the dragend JS framework
I know this is really stupid question, but have someone used dragend JS
for websites to be used in iPad?
I have worked on the site and now stuck on a problem that no link is
working in iPad on my site. On normal desktop computers, it works.
When I went to the official site, to my surprise, the links also don't
work there too ... You can test this site
http://stereobit.github.io/dragend/ on your iPad.
I'll be very thankful for any assistance as I've been literally using
different scenarios but to no avail.
Many Thanks

Rails 4: coffeescript only works when there is a post request or when i reload the page
Rails 4: coffeescript only works when there is a post request or when i
reload the page
i am mostly a backend developper and am not so skilled in javascript
related stuff (and all the galaxy of frameworks that exists on the place).
I know that's bad but it is what it is.
i'm becoming crazy about the issue I have and i'm probably missing
something very basic. i made some researches (Google + the stack overflow
bible) and didn't find any case similar to the issue I have. i suppose i
just don't know what I'm doing. let me explain.
What's happening
I am using Rails 4 for a small (useless) project and I try to write some
javascript "code" in the coffeescript files.
apparently, the coffeescript "code" i wrote only works when I reload a
page, or after a POST request (when you submit a form for example). On GET
requests, during navigation from page to page for example, nothing is
happening.
I tried with a very simple basic elementary 101 test: displaying an alert
message (Hello!) on a page (It started by including a date picker).
let's say i have an Article model and an associated ArticlesController to
edit/create/delete data. I have the following files :
app/assets/javascripts/application.js
app/assets/javascripts/articles.js.coffeee
app/controllers/articles_controller.rb
app/models/article.rb
app/views/articles/new.html.erb
app/views/articles/index.html.erb
etc.
I am just adding one line in app/assets/javascripts/articles.js.coffee :
alert "Hello!"
If I submit a form or I reload a page, I see the alert "Hello!". If I just
click on a link, to edit an article for example, nothing is happening.
The logs
When I look at the rails logs in the two cases, I have two different
scenarios:
In the "it's not working" case, when I do a simple get request (by
clicking on the edit link), I have this in the logs :

What I tried
I tried to generate the js files with
rake assets:precompile
but it was the same.
I tried to install some gems like therubyracer, barista, it was the same.
Am I missing something very basic? Should I read a book about the bases of
javascript? Should I be deported in Alaska for not understanding something
very easy ? Should I retire or change job ?
Thanks for the help. I am sinking into depression.
reload the page
i am mostly a backend developper and am not so skilled in javascript
related stuff (and all the galaxy of frameworks that exists on the place).
I know that's bad but it is what it is.
i'm becoming crazy about the issue I have and i'm probably missing
something very basic. i made some researches (Google + the stack overflow
bible) and didn't find any case similar to the issue I have. i suppose i
just don't know what I'm doing. let me explain.
What's happening
I am using Rails 4 for a small (useless) project and I try to write some
javascript "code" in the coffeescript files.
apparently, the coffeescript "code" i wrote only works when I reload a
page, or after a POST request (when you submit a form for example). On GET
requests, during navigation from page to page for example, nothing is
happening.
I tried with a very simple basic elementary 101 test: displaying an alert
message (Hello!) on a page (It started by including a date picker).
let's say i have an Article model and an associated ArticlesController to
edit/create/delete data. I have the following files :
app/assets/javascripts/application.js
app/assets/javascripts/articles.js.coffeee
app/controllers/articles_controller.rb
app/models/article.rb
app/views/articles/new.html.erb
app/views/articles/index.html.erb
etc.
I am just adding one line in app/assets/javascripts/articles.js.coffee :
alert "Hello!"
If I submit a form or I reload a page, I see the alert "Hello!". If I just
click on a link, to edit an article for example, nothing is happening.

System calls - Opensuse
System calls - Opensuse
My initial attempts to build a system call with the help of this question
My distro information: Linux linux-epq2.site 3.7.10-1.16-default #1 SMP
Fri May 31 20:21:23 UTC 2013 (97c14ba) x86_64 x86_64 x86_64 GNU/Linux
In the current version of my program, that will allow me to embed this as
a system call does have a main (stupidity to even say that, but just to
make things more explicit).
In my current program:
It takes in two inputs from the user, and does some calculations and gives
the output as the graph and some data.
My initial attempt was to call that program via execlp available in unistd
library like this:
#include<linux/linkage.h>
#include<linux/kernel.h>
#include<unistd.h>
asmlinkage long graph(const char* granularity, char* application)
{
pid_t child;
child = fork();
if (!child) {
execlp("./system-call", granularity, application, NULL);
}
sleep(0.2);
return 0;
}
But when I am trying to compile the kernel (note: same kernel version) and
the old config file (if necessary i'll also upload the config file). I get
the following error:
linux-3.7.10 % make
make[1]: Nothing to be done for `all'.

Why is declaration of class in file included in separate function clashing with include in other function? (example code included)
Why is declaration of class in file included in separate function clashing
with include in other function? (example code included)
My understanding of including a file in a function was that it stays
within that function scope:
If the include occurs inside a function within the calling file, then all
of the code contained in the called file will behave as though it had been
defined inside that function. So, it will follow the variable scope of
that function.
But when I do this, the second one clashes with the first and tells me the
class is already declared!
Run this php page to see the errors (you'll need all three PHP pages)
<?php
class TestOnce
{
function __construct()
{
$this->includeOnce();
}
function includeOnce()
{
//This should include it once
include_once "once.php";
var_dump( $once );
}
function includeSomethingThatIncludesOnce()
{
include_once "includeonce.php";
var_dump( $once );
}
}
$test = new TestOnce();
$test->includeSomethingThatIncludesOnce();
?>
This also inlcudes once, but is told it's already included which it
shouldn't be in that function/
<?php
//This should include it once
include "once.php";
var_dump( $once );
?>
This is "once" which declares the class and an instance variable
<?php
class Once
{
}
$once = new Once();
?>
Why aren't the includes restricted to the scope of the function? How would
I achieve that?

How to write services with $q and $http calls without being repetitive
How to write services with $q and $http calls without being repetitive
I'm trying to figure out an elegant way to write AngularJS services
without being so repetitive with the $q syntax.
Currently, I'm writing services like follows:
(function() {
function ServiceFactory($q, $timeout, $http) {
return {
getFoo: function() {
var deferred = $q.defer();
$timeout(function() {
$http.get('/the/foo/thing').then(function(response) {
if (response.isError) {
deferred.reject();
} else {
deferred.resolve(response.data.foo);
}
}, function() {
deferred.reject();
});
});
return deferred.promise;
}
};
}
angular.module('myapp').service('MyService', ['$q', '$timeout',
'$http', ServiceFactory]);
}.call(this));
It works very well, buy I'm always writing down a bunch of code just to
delay $http.get and expose a Promise. Sometimes I will have some extra
stuff into success callback, like handling data, creating a different
response object... But most of the time, is just like the code above: call
$q.defer + $http.get().then... + return promise
So, I'm thinking about a way to clean up/reduce the code without affecting
the clarity of what I'm doing, e.g if another developer open the file, it
should not be a mystery.
As a side note, the $http service here is actually a decorator, handling
server responses to give me a more structured object with things like
response.isError and response.data.
Also, I have seen a similar solution in another question {1}, but this is
not as same. Just returning the response of $http.get().then() will expose
the entire response to controllers on response, and it is not the desired
effect. Instead, when I call MyService.getFoo().then(...), I'm expecting a
foo object as a response from service, fed by server via
response.data.foo, or a call to errorCallback.

Will saving innerhtml allow to save all elements on page
Will saving innerhtml allow to save all elements on page
I need to save a web page the content of which changes dynamically. For
example, a user can add custom functions and they are added to the custom
functions drop down list. I would like to save the "newly" updated page
using PHP and AJAX. I tried getting the innerHTML of all the elements by
wrapping them in a "main-body" div. When I display the result with the
alert box, all the data seems to be captured. But when I post the data to
my savedata.php file using the POST AJAX method the data is not saved.
Only the first few lines of the data is saved.
The new options in the select boxes and the content of the textarea are
not saved either. However, if I individually try to save the textarea and
select box data using .value instead of innerHTML that works.
My question in a nutshell, is why doesn't the innerHTML data get saved
despite the fact that the alert box shows all the data when I use
documentGetById("main-body").innerHTML to get all the contents of my page.
Here is some code
Javascript and AJAX Code
function savehtml()
{
//Make ajax call after setting up variables
var saveme=document.getElementById('txtArea').innerHTML
var filename = document.getElementById('nameoff').value
var parameters="saveme="+saveme+"&filename="+filename
ajaxr('savedata.php', "result", parameters)
}
function ajaxRequest(){
var activexmodes=["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"]
if (window.ActiveXObject){
for (var i=0; i<activexmodes.length; i++){
try{
return new ActiveXObject(activexmodes[i])
}
catch(e){
//suppress error
}
}
}
else if (window.XMLHttpRequest) // if Mozilla, Safari etc
return new XMLHttpRequest()
else

I need to save a web page the content of which changes dynamically. For
example, a user can add custom functions and they are added to the custom
functions drop down list. I would like to save the "newly" updated page
using PHP and AJAX. I tried getting the innerHTML of all the elements by
wrapping them in a "main-body" div. When I display the result with the
alert box, all the data seems to be captured. But when I post the data to
my savedata.php file using the POST AJAX method the data is not saved.
Only the first few lines of the data is saved.
The new options in the select boxes and the content of the textarea are
not saved either. However, if I individually try to save the textarea and
select box data using .value instead of innerHTML that works.
My question in a nutshell, is why doesn't the innerHTML data get saved
despite the fact that the alert box shows all the data when I use
documentGetById("main-body").innerHTML to get all the contents of my page.
Here is some code
Javascript and AJAX Code
function savehtml()
{
//Make ajax call after setting up variables
var saveme=document.getElementById('txtArea').innerHTML
var filename = document.getElementById('nameoff').value
var parameters="saveme="+saveme+"&filename="+filename
ajaxr('savedata.php', "result", parameters)
}
function ajaxRequest(){

for (var i=0; i<activexmodes.length; i++){
try{
return new ActiveXObject(activexmodes[i])
}
catch(e){
//suppress error

Sort NSNumber with NSSortDescriptor
Sort NSNumber with NSSortDescriptor
I have a Route as my top level Core Data entity. Then a Route has
Locations. The Locations have a
@property (nonatomic, retain) NSNumber *index;
I need the index because I need to make sure the user's route is in order.
I was wondering how I can best sort on the Locations entity. In my
tableView, I show the name of the Route. Then when the user clicks on the
Route, I show the Locations. I saw NSSet has
sortedArrayUsingDescriptors
but I wasn't aware of how I could sort NSNumber with a sortDescriptor. I
have seen people just use code like
sortedArrayUsingSelector:@selector(compare:) // or something like that
I can write a simple convenience method to iterate through the NSSet and
return the Location objects by their index, but wasn't sure if there was a
better way. Thanks in advance!

Access: Entering multiple subform values with one entry in the form
Access: Entering multiple subform values with one entry in the form
I've been using Access to create simple databases for a while with great
success, but have run into a problem I can't find an answer to.
We ship individualized serialized units to various end-users, and
occasionally to resellers that stock them for end-users. I must keep track
of which serial numbers end up with each end-users.
The first database I created to handle this recorded company information
in one table using their account number as primary key, order information
in a second table using the order number as the primary key and linked via
the company name, and unit information in a third table with the serial
number as the primary key and linked via the order number.
This worked very well until I had to account for these stock orders with a
reseller. As it was structured, every unit was linked to one company via
the sales order. The issue is that I may ship 20 units on one order to
Company A, who then sells 5 to Company B and 3 to Company C.
I realized I needed to link the company name directly to the units, not
the orders and have fixed that.
My issue now is simplicity in entering information in the form. My
previous database involved the employee in our shipping department merely
entering the sales order, selecting the customer name from a drop down
menu, then scanning the serial numbers in a subform. This was to ensure
simplicity and try to eliminate human error. He had only three things to
input, and most of the input was done by scanning barcodes.
As it is currently structured now, the employees out in shipping would
have to populate the company name for every record in the subform with the
serial number and that complicates things in a way that is unacceptable.
At the point of shipping, the company name will always be the same for
every unit in the subform.
So.
How would I go about creating a form where the company name is entered
once in the form, and automatically populates itself for every record in
the subform? The caveat here is that I must also be able to go back
occasionally and change the company name of individual units in an order
without necessarily affecting the rest of the order. I suppose it starts
out as a one-to-many relationship that then must be able to change.
I hope that makes sense.
I have looked for answers using various approaches with auto-fill and
relationships and not preserving data integrity, but I feel the answer is
just beyond my reach.
The only solution I can think of is to create another field in the unit
table for the end-user, and perhaps write a formula that sets this default
value as the company name from the order that shipped it. This seems
unnecessarily complicated and redundant, there has to be a better way.

How to pass a function and a list of its vector arguments?
How to pass a function and a list of its vector arguments?
I'm trying to write a function in R that will take as arguments, a second
function and its arguments, some of which are vectors. The ultimate result
I want is to write a rolling function that calls a function to act on a
time series, but I've tried all permutations of "apply" functions I can
think of with no success, since "apply" functions all seem to apply a
function to a vector element by element and what I want is to apply
functions to vectors as a whole. For example,
a = c(1,2,3); b = c(4,5,6)
sapply(a,function(x,y,c) c*t(x)%*%y,b,c=2)
[,1] [,2] [,3]
[1,] 8 16 24
[2,] 10 20 30
[3,] 12 24 36
but what I really want is:
2*t(a)%*%b
[,1]
[1,] 64
and be able to roll the function along a time series. I've also tried
writing a generic function that contains a second function and its
parameters as arguments, but I can't seem to get it to accept the
parameters. For example,
foo <- function(func,parm){
return(func(parm))
}
foo(function(x,y,c) c*t(x)%*%y,parm=list(a,b,c=2))
Error in c * t(x) %*% y : 'c' is missing
The problem here is that func won't accept a list of arguments, but how
does one pass a list of arguments to a function? Hope this isn't too
confusing. Thanks for any help offered.

video set to "true" in Skype video chat URI, but video is not enabled when call starts
video set to "true" in Skype video chat URI, but video is not enabled when
call starts
I'm using the Skype API from their site: skype apir/uri for video call
which saiys the following URI "Calls other people on Skype, and
automatically turns on the call originator's video":
skype:skypeUserName?call&video=true
when I start the intent, it places the call successfully, but the video is
NOT enabled, on either phone by default.
One suspicion I have is maybe everything after the question mark is
getting stripped. this is how I pass it in:
static String skypeURI = "skype:stablesentryremote?call&video=true";
public void initiateSkypeUri(Context myContext, String mySkypeUri) {
// Create the Intent from our Skype URI
Uri skypeUri = Uri.parse(mySkypeUri);
Intent myIntent = new Intent(Intent.ACTION_VIEW, skypeUri);
}
But this could just be a skype bug.
