I am working on a project where i have to pack inner boxes which contain car parts inside a outer box for exporting .
There are three type of Inner boxes(Form of Cuboid) .If volume of outer box is V then volume of Inner boxes are V/20,v/40,V/80 . Height of each inner box is same.
I want to fill the inner boxes most efficiently in outer box:
Outerbox weight should not exceed 1 ton
Outerbox should be filled with 100% efficiency
Which algorithm should I use?

The problem is the previous developer who built it tested it on an Apache webserver using his local server and it works perfect (I have tested it myself) now the remote server is actually an IIS server. After modifying curl file to accept username and password. I have managed to connect to the IIS web server but it does not upload any files. The error returned is "Failed to Write" but all the permission is set to complete control (read write and execute).
The upload handler is a PHP file on the server. I have set up PHP on the IIS server.
I am not understanding what the problem may be? Is it because Curl has some problems with IIS or is there something which I have forgotten to include in the IIS configuration.
Any suggestion would be really helpful and if any information any of you need please do ask.
Thanks in advance. | c++ | http | iis | webserver | libcurl | null | open | Using Curl wiith IIS to upload files using HTTP

Is using MySQLi prepared statments completely invunerable to SQl injection? For example see my code below, am I correct in thinking I can use the $_POST variable straight from the user without any injection protection? For the purpose of this question please ignore validating data to make sure it is the correct format for my database (I always do that anyway), I'm more focussing on security here.
$mysqli=new mysqli($host, $user, $password, $database);
$stmt=$mysqli->stmt_init();
$stmt->prepare('INSERT INTO `tablename` (`column`) VALUES (?)');
$stmt->bind_param('s', $_POST['value']);
$stmt->execute();
$stmt->close();
$mysqli->close();
Also is my code correct? This only the second or third time I have written a prepared statement using the MySQLi class. Although it works, I was wondering if I am doing everything correctly? Could any part of that script be considered bad practice?
Lastly, how would I go about doing multiple prepared statements that use the same database connection? Do I just use the close() method on the $stmt and then initialize another $stmt class?

We have this simple class hierarchy:
------------------------------------
class A {};
class DA : public A {};
class DDA : public DA {};
And we have the following functions operating on these classes:
---------------------------------------------------------------
void f(A x) {
std::cout << "f A" << std::endl;
}
void f(DA x) {
std::cout << "f DA" << std::endl;
}
void f(DDA x) {
std::cout << "f DDA" << std::endl;
}
Now we want to add another function that treats DA a little different.
(1) A first attempt could look like this:
-------------------------------------
void g(A t) {
std::cout << "generic treatment of A" << std::endl;
std::cout << "called from g: ";
f(t);
}
void g(DA t) {
std::cout << "special treatment of DA" << std::endl;
std::cout << "called from g: ";
f(t);
}
But calling this with an object of each of the classes clearly does not have the desired effect.
Call:
A a; DA b; DDA c;
g(a); g(b); g(c)
Result:
generic treatment of A
called from g: f A
special treatment of DA
called from g: f DA
special treatment of DA
called from g: f DA //PROBLEM: g forgot that this DA was actually a DDA
(2) So instead we might try to use templates:
-----------------------------------------
template<typename T>
void h(T t) {
std::cout << "generic treatment of A" << std::endl;
std::cout << "called from h: ";
f(t);
}
template<>
void h<>(DA t) {
std::cout << "special treatment of DA" << std::endl;
std::cout << "called from h: ";
f(t);
}
which results in:
generic treatment of A
called from h: f A
special treatment of DA
called from h: f DA
generic treatment of A //PROBLEM: template specialization is not used
called from h: f DDA
Well, how about we don't use template specialization but define a non-template function for the special case? ([Article][1] on the very confusing matter.) It turns out it behaves in exactly the same way because the non-template function which is according to the article a "first class citizen", seems to lose because a type conversion is necessary to use it. And if it would be used, well then we would just be back at the first solution (I assume) and it would forget the type of DDA.
(3) Now I came across this code at work which seems rather fancy to me:
-------------------------------------------------------------------
template<typename T>
void i(T t, void* magic) {
std::cout << "generic treatment of A" << std::endl;
std::cout << "called from i: ";
f(t);
}
template<typename T>
void i(T t, DA* magic) {
std::cout << "special treatment of DA" << std::endl;
std::cout << "called from i: ";
f(t);
}
But it seems to do exactly what I want:
generic treatment of A
called from i: f A
special treatment of DA
called from i: f DA
special treatment of DA
called from i: f DDA
Even though it needs to be called in a weird way:
i(a, &a); i(b, &b); i(c, &c);
Now I have several questions:
1. Why the hell does this work?
2. Do you think it is a good idea? Where are possible pitfalls?
3. Which other ways of doing this kind of specialization would you suggest?
4. (How do type conversions fit into the madness that is template partial ordering and such...)
I hope this was reasonably clear. :)

I want to modify the default queryset in order to work proficiently with the db, to do this I need to use a `GROUP BY`. I know that I can do this which gets me the SQL I am after:
query = Variant.objects.all().query
query.group_by = ['name']
return QuerySet(query=query, model=Variant)
And this will result in the queryset that I am after. So I built a queryset Manager to help me out. The problem is that it's returning the right values but when I do a count on it it's wrong.
class VariantQuerySet(QuerySet):
def group_by_name(self):
self.query.group_by = ['name']
return self.filter()
class VariantManager(models.Manager):
def get_query_set(self):
return VariantQuerySet(self.model, using=self._db)
But then when I start playing with it..
>>> Variant.objects.filter(project__name__icontains="zam")
[<Variant: RevA>, <Variant: RevA>, <Variant: RevA>, <Variant: revB>, <Variant: RevC_Fiendish>, <Variant: RevA>, <Variant: RevA_tapeout>]
>>> Variant.objects.filter(project__name__icontains="zam").count()
7
>>> Variant.objects.filter(project__name__icontains="zam").group_by_name()
[<Variant: RevA>, <Variant: revB>, <Variant: RevC_Fiendish>, <Variant: RevA_tapeout>]
So far so good. 7 ungrouped items, 4 with grouping.
>>> Variant.objects.filter(project__name__icontains="zam").group_by_name().count()
7
So why is my count still stuck at 7 - it should be 4? I've I thought _result_cache was holding the value so I set that to None in the method but no luck. Any ideas why this is wrong?

So far, the biggest issue I faced is the dynamic allocation of arrays based on index specification. For example, using Matlab, typing the following:
x = [1 2];
x(5) = 3;
would result in:
x = [ 1 2 0 0 3]
In other words, I didn't know before hand the size of (x), nor its content. The array must be defined on the fly, based on the indices that I'm providing.
In python, trying the following:
from numpy import *
x = array([1,2])
x[4] = 3
Would result in the following error: IndexError: index out of bounds. On workaround is incrementing the array in a loop and then assigned the desired value as :
from numpy import *
x = array([1,2])
idx = 4
for i in range(size(x),idx+1):
x = append(x,0)
x[idx] = 3
print x
It works, but it's not very convenient and it might become very cumbersome for n-dimensional arrays. Anybody knows of a better approach. I though about subclassing ndarray to achieve my goal, but I'm not sure if it would work. Let me know if you have any suggestion.

I have a UITabBarController with 2 tabs, each of the tabs leads to a Nav controller with a stack of VC.
The last view Controller on the 1st tab path will show an image. I would like that image to be stored in a table and viewed anytime the second tab is selected.
How do I send this image from the 1st tab-> NaVController->last VC (image VC) to 2nd tab -> NavController->table VC?
I have a couple of options:
1- Create a class method in the tableVC and have the imageVC call that class method and pass that image to be saved directly into user defaults. This seems to go against MVC
2- Create a protocol in imageVC with a method and delegate property and have the table VC adopt that method to save the image in an array. The problem here is that the only place to set the delegate is in ViewDidLoad:
[[[[self.tabBarController.viewControllers objectAtIndex:0] viewControllers] objectAtIndex:1] setDelegate:self];
The problem here is that if the user select the second tab from the start, the app will crash because obviously the viewControllers have not been loaded on the nav stack for the first tab. In the same token, if the user sees 1 image first and then selects the second tab, it will execute and set the delegate but without saving that first selected image.
There must be an easier way.....
Thanks in advance

So carrying this over to python:
I have 2 files:
1) the implementation file = accountClass.py and
2) the interface file = useAccountClass.py
I have compiled the implementation file and have obtained the .pyc file. So when I provide my code to someone else, I would provide him with the .pyc file and the interface file, right?
Also, if I provide someone else with ONLY the .pyc file, can I expect him to write the interface on his own? I'm going to say no. But there's this one nagging doubt that I have:
The creators of numpy and scipy did not share the implementation with us end users. And I don't think they shared any interfaces either. But we can still search for the different classes and their methods inside both numpy and scipy. So, using this example of numpy and scipy, I guess what I'm trying to ask is:
Is it possible for someone else to create an interface to my code if I provide him/ her with only the compiled implementation file (in this case accountClass.pyc)? How will that person know what classes and methods I have defined in my implementation? I mean, will they use the

So here is the weird thing: It works in phpmyadmin just fine and pretty fast too. Also.. it works fine with the Zend_DB when it is a little smaller (i.e some less keywords). The thing is that I cannot find anywhere in Zend_DB documentation that queries should be limited in size or whatever. So anyone knows a solution?
With:
$mysqli = new mysqli('localhost', 'root', '', 'table');
$r = $mysqli->query($not_really_big_query_but_zend_db_thinks_it_is);
$p = array();
while ($row = $r->fetch_assoc()){

Everything goes smooth as expected, no problems with how big my query is whatsoever. So what is Zend_db doing wrong. I don't really want to rewrite everything back.

I mean I could make a sprite image and position each link/icon absolute so that when the hover state occurs they don't push each other. However the problem is the clickable area will grow with the hover state thereby overlapping the other buttons and making them hard to click.
Any suggestions/ideas would be greatly appreciated.

I have a class called Application which extends Controller class. In most examples around the web, I see controllers like the following.
public class Application extends Controller {
public static void index() {
render(arg0,arg1,...);
}
public static void tasks() {
render(arg0,arg1,...);
}
public static void newTask() {
render(arg0,arg1,...);
}
public static void deleteTask(Long id) {
render(arg0,arg1,...);
}
}
However in my default application, I can only do the following. I don't know how to do the previous one.
public class Application extends Controller {
public static Result index() {
return ok("Hello World!");
}
public static Result tasks() {
return ok(indexabc.render("hello world"));
}
public static Result newTask() {
return TODO;
}
public static Result deleteTask(Long id) {
return TODO;
}
}
In my code when I try to replace "Result" return type with "void", there is no problem. However, when I want to call "render()" method with some parameters, that method doesn't exist. I can't find a way for how to call render function. Waiting for your answers. Thanks. | controller | playframework | render | null | null | null | open | render function doesn't exist in play framework 2.0.2?

When you are typing first time it displays everything ok. But if you change search text it will now show both results. For example, if you type "A" it will show results which starts <b>only with "A"</b> but when you delete the text and type type "B" instead it will show results which starts with <b>"A" or "B"</b>. Then if you type in "A" again it will continue to duplicate values. It took about two hours but I can't find out solution. How can I fix that?
Any help is appreciated. | c# | silverlight | autocompletebox | null | null | null | open | Silverlight AutoCompleteBox duplicates items
