Eg:
class CopyOnReadList<T> {
private final List<T> items = new ArrayList<T>();
public void add(T item) {
items.add(item);
}
public List<T> makeSnapshot() {
List<T> copy = new ArrayList<T>();
synchronized (items) {
// Make a copy while holding the lock.
for (T t : items) copy.add(t);
}
return copy;
}
}
(Code lovingly borrowed from [this excellent answer][1])
In this code snippet, can one thread call `add` while another is calling `makeSnapshot`?. Ie., does the lock created by `synchronized (items)` affect all attempted reads to `items`, or only those attempted through the `makeSnapshot()` method?
The original post actually used a `synchonized` lock in the add method:
public void add(T item) {
synchronized (items) {
// Add item while holding the lock.
items.add(item);
}
}
What is the side effect of removing this?

How do i check that how much time a process has been in idle state.
my actual problem:
I have a process which runs on solaris unix X86 server.
In our test servers its finishes its job in 4 hours.But in our client servers its taking more than than 10 hours.I checked in the client server and found that the configuration in our client server is different from our test server.for eg:
number of virtual processors in testserver are-24 but in client server are only 8.
and processor speed also differs.
I suspect it is because of the configuration that the process is not actually getting the cpu time and i suspect that it is idle for most of the time.

When opening a Youtube video page, page loading process does not end even when all the content (text, images) is loaded; loading ends only when **video buffering** completes! Also, when I interrupt the loading (by pressing `Esc`, for example) video downloading is also stopped! (Until now I had to right click on the video and press _Stop Download_ to abort buffering).
IMHO that's a great user experience and a big step for making the Flash-based content behave like ordinary web content.
My question is: how this is done?!
I thought they're simulating some loading process until the buffering completes. Also they should have handled the `window.onAbort` event or something, in order to "tell" the Flash to stop buffering. I tried to catch that event using Chrome's DOM Inspector, but no luck...
Or... do they use some special API that is currently available only in Chrome? There is no such behavior on FF4 right now. | javascript | flash | youtube | null | null | null | open | How does Youtube control Flash content loading (Chrome 12)

I would like a keyboard to appear when I click in a TextBox field. Is there a way to use the built-in on screen keyboard for this?
The first monitor I tested with was a Wacom. It is an older unit that uses a pen. It had some software that pulled up an on screen keyboard whenever I clicked in any text field (in any application). It was very handy. I thought this feature was using built-in Windows Tablet software because it didn't look like it came from a third party.

class A {
void f() { doSomethingA(); }
}
class B : public A {
void f() { A::f(); doSomethingB(); }
}
However, when I do this, `A::f` gets called with `this == 0`, which obviously results in segfault. Am I doing something wrong, or is this simply not possible? My current option is to resort to static functions and pass the object explicitly, but I'd prefer it this way.
Yes, I could call them differently, but that kind of defeats the purpose of making them look similar to the programmer. And I can't make them virtual for various reasons (the most prominent being the role-migration, that I actually want different behavior depending on what I use it as).
Any help appreciated

My problem:
I make a program for taking screenshots from the game, this is the current code that I use:
Dim bounds As Rectangle
Dim screenshot As System.Drawing.Bitmap
Dim graph As Graphics
bounds = Screen.PrimaryScreen.Bounds
screenshot = New System.Drawing.Bitmap(bounds.Width, bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb)

graph.CopyFromScreen(bounds.X, bounds.Y, 0, 0, bounds.Size, CopyPixelOperation.SourceCopy)
PictureBox1.Image = screenshot
and it works great when i need to take a desktop screenshot, but when i try take a game screenshot it does not work! I read on the internet and it says that I need to take screenshots from DirectX. The problem is that I never worked with DirectX and I need your help, any help is welcome if it is related to my problem, I would appreciate if you have some kind of example.

</pre>
</code>
The table above have all open invoices for a customer. I need to apply a payment to these invoices starting from the oldest invoice (daysOpen column in the table). So if I have a $550.00 payment, I'll first apply it to the invoice with 123 daysOld, that's $491.96 -$500 (which leaves $8.04 to be applied to the next invoice... and so on), then update that record (balance column in table) to 0.00 and move to the next and apply the remaining. That would be $4911.37 - $8.04, which would leave $4903.33. Since there is no balance left to be applied, the loop exits.
The balance column should now read
<pre>
0
4903.33
3457.69
</pre>
Note: I need to do this for all customers in a table (around 10,000). A customer has an average of about 20 invoices open.

I have noticed that most MVC frameworks will have the `Models` `Views` and `Controllers` folders. In a large project this doesn't make sense to me. In my example let's assume I am building a social network site. It would have many `sections`, `users`, `messaging`, `blogs`, `chat`, `wall`, `groups`, `events`. These are just ideas for an example...
So if a larger project like that had all the `Models`, `Views`, and `Controllers` crammed into those **3** folders, it would be chaos.
So I am thinking of doing my MVC into sections or `Modules` so that each main section gets it's own folder and then it's own set of `MVC` folders like the demonstration below....
root/
----/.htaccess
----/index.php
----/assets/
----/Modules/
------------/Core/
-----------------/Models/
-----------------/Views/
-----------------/Controllers/
-----------------/Helpers/
-----------/Users/
-----------------/Models/
-----------------/Views/
-----------------/Controllers/
-----------/Messages/
--------------------/Models/
--------------------/Views/
--------------------/Controllers/
----------/Photos/
-----------------/Models/
-----------------/Views/
-----------------/Controllers/
----------/ etc.....etc...all the other "Modules"
----/library/
------------/Database/
------------/Router/
------------/Template/
------------/.....etc...etc
----------
Now I am just looking to ask other's with more experience, does this seem like a good idea, I didn't see it in use too often by other projects which is why I question it.
Also the file structure would route everything through `index.php` and all the `Module` folders would get there own name in the URI. So `root/modules/users` would be routed to ` domain.com/users` and things inside the `root/modules/core` would be routed to ` domain.com/` so they are like the main site
Any improvements? See anything I am possibly missing to make a good MVC design work with this structure?
I appreciate any feedback

I have photos taken with a camera of food labels for a project I'm working on. I was able to use the cvHoughLines2 function to draw red lines over the lines/bars on the photo.
What I want to do now is to chop up the image into several smaller images based on the Hough lines - so that each "line" (e.g. the "calories" line, "protein" line, etc) of the food label is separated into new images.
Since I have no idea how to do this, is there someone who could point me somewhere or teach me how to do this?

My programming skills are very basic that I don't consider it a professional skill, but more of a hobby skill.

Do you agree with these 3 conclusions?
Initially, we were thinking of agreeing to a telecommute arrangement, but I personally prefer they work on-site at our temporary office and do the programming there because my concern is: we are building a business that relies 100% on codes, to operate, shouldn't it make sense that the company and no one else (not even the programmers) have their own copy of the source codes for security purposes. Am I looking at this correctly or am I being paranoid?

I have a friend who works for an IT company (not the IT dept, but sales) and what he's shared (observed from their office procedures) were: IT personnel especially cannot use mobile phone/thumb drives/etc in the office. Their work computer (where they do the programming) doesn't have input/output ports (so you can't copy works done) and no internet... so it's basically an isolated machine to do dev work. I was thinking of adopting this practice if we go for office-based, but my concern is the internet access which i think programmers need? Could you please help me with a set-up that can address both concerns can provide programmers with needed resources (ie internet) but at the same time must prevent pirating of whatever the team's working on, raw codes... please do suggest a sensible and effective set-up that won't stifle the programmers and protect us as well...

} else {
echo 'View not found';
return FALSE;

} else {
return FALSE;
}

From the file which I included the libraries, I am able to write something like `$form->value('name');` without errors. However, if I do something like this:
`$view->load('folder/index', array('var_name' => 'var_value'));` then from the `folder/index.php` file I can access `$var_name` just fine, but not `$form->value('name');`. I get errors such as `Call to a member function value() on a non-object in ...`
My question is how can I organize my libraries and classes in a way that will be reusable. I don't want to use a front loader (an `index.php` file that everything runs through first). This may be an issue with the way I wrote my classes, but I imagine it's a larger issue regarding where things are located etc. | php | codeigniter | object | frameworks | organization | null | open | Php - organizing objects and libraries
===
I've been creating a small number of libraries / classes from scratch in php. I come from a codeigniter background, and I'm trying to make some libraries with similar functionality. I keep running into issues regarding objects.
Is the best way to create a super object `$this` somehow? My main issue is that I've created a view object and I run a function called `load` which looks like so:
class View {
public function __construct() {
}
public function load($file = NULL, $data = array()) {
if($file) {
$file .= '.php';
if(file_exists($file)) {
// Extract variables BEFORE including the file
extract($data);
include $file;
return TRUE;
} else {
echo 'View not found';
return FALSE;
}
} else {
return FALSE;
}
}
}
Then in my php file, I have at the top `include 'libraries.php';` which looks like:
include 'database.php';
include 'view.php';
include 'input.php';
include 'form.php';
$config = array(
'host' => 'localhost',
'username' => 'username',
'password' => 'password',
'database' => 'database'
);
$database = new Database($config);
$view = new View();
$input = new Input();
$form = new Form();
From the file which I included the libraries, I am able to write something like `$form->value('name');` without errors. However, if I do something like this:

So i assume that this is a bug in the framework itself. Have anyone of you faced this before? If so what is the best bypass method available to get all 404 pages return custom page?

A little theory, before we begin. Nyquist's sampling theorem suggests that an increase in one bit of resolution requires four additional samples, and in general, n more bits requires 2^(n+1) more samples. I'm simulating a perfect 10 bit ADC which returns a value from 0..1023 monotonically and with no noise for an input from 0-2V.
To gain more bits, it is necessary to add randomly distributed noise (it doesn't have to be actually random, but it does have to *appear* random, like white noise.) The problem I'm having is although the resolution is increasing, the actual reading is offset by some small negative amount. Here's one sample output for an input of 1 volt (reference is 2 volts, so the count should be exactly half for an monotonic ADC):
10 bits: 512 volts: 1.0
11 bits: 1024 volts: 1.0
12 bits: 2046 volts: 0.9990234375
13 bits: 4093 volts: 0.999267578125
14 bits: 8189 volts: 0.999633789062
15 bits: 16375 volts: 0.999450683594
16 bits: 32753 volts: 0.999542236328
17 bits: 65509 volts: 0.999588012695
18 bits: 131013 volts: 0.999549865723
24 bits: 8384565 volts: 0.999518036842
28 bits: 134152551 volts: 0.999514393508
In fact, no matter how many times I run the simulation I'm always ending up with around ~0.9995, instead of 1; and the last value should be 134,217,728, not 134,152,551, which is about 65,771 out - or around 1/4 of the extra 18 bits of resolution (coincidence? I am diving by 4.) I suspect my PRNG is biased in some way, but I am using the default Mersenne Twister that comes with Python.

I'd appreciate any suggestions on this. My plan is eventually to take this to a low cost microcontroller to implement a high resolution ADC. Speed will be fairly important, so I will probably be using an LFSR to generate PRNG bits, which won't be half as good as a Mersenne twister but should be good enough for most uses, and hopefully good enough for this. | python | algorithm | statistics | null | null | null | open | What is causing a negative bias in my super-sampling simulation?
===
I'm developing a little test program to see if it is feasible to add noise to an ADC to gain oversampled bits. A little theory, before we begin. Nyquist's sampling theorem suggests that an increase in one bit of resolution requires four additional samples, and in general, n more bits requires 2^(n+1) more samples. I'm simulating a perfect 10 bit ADC which returns a value from 0..1023 monotonically and with no noise for an input from 0-2V.
To gain more bits, it is necessary to add randomly distributed noise (it doesn't have to be actually random, but it does have to *appear* random, like white noise.) The problem I'm having is although the resolution is increasing, the actual reading is offset by some small negative amount. Here's one sample output for an input of 1 volt (reference is 2 volts, so the count should be exactly half for an monotonic ADC):
10 bits: 512 volts: 1.0
11 bits: 1024 volts: 1.0
12 bits: 2046 volts: 0.9990234375
13 bits: 4093 volts: 0.999267578125
14 bits: 8189 volts: 0.999633789062
15 bits: 16375 volts: 0.999450683594
16 bits: 32753 volts: 0.999542236328
17 bits: 65509 volts: 0.999588012695
18 bits: 131013 volts: 0.999549865723
24 bits: 8384565 volts: 0.999518036842
28 bits: 134152551 volts: 0.999514393508
In fact, no matter how many times I run the simulation I'm always ending up with around ~0.9995, instead of 1; and the last value should be 134,217,728, not 134,152,551, which is about 65,771 out - or around 1/4 of the extra 18 bits of resolution (coincidence? I am diving by 4.) I suspect my PRNG is biased in some way, but I am using the default Mersenne Twister that comes with Python.
