If I have called assert(original.valid?) _before_ cloning, then the clone passes the validates_presence_of test even after I have set member_id value to nil.
The two tests below illustrate this. In test one, the clone is created _before_ the original ("contact") is validated. Clone correctly fails the validation when member_id is missing. Assertion C succeeds.
In test two, the clone is created _after_ the original is validated. Even though clone.member_id is set to nil, it _passes_ the validation. In other words, assertion 2C fails. The _only_ difference between the tests is the order of the two lines:
cloned = contact.clone
assert(contact.valid?,"A")

The problem asks the number of solutions to the Diophantine equation of the form <i>1/x + 1/y = 1/z</i> (where <i>z = n!</i>). Rearranging the given equation clearly tells that the answer is the number of factors of <i>z<sup>2</sup></i>.
So problem boils to find the number of factors of <i>n!<sup>2</sup></i>.
My algorithm is as follows
1. Make a boolean look up table for all primes <= n using Sieve of Eratosthenes algorithm.
2. Iterate over all primes <i>P</i> <= <i>n</i> and find its exponent in <i>n!</i>. I did this using step function formula. Let the exponent be <i>K</i>, then the exponent of <i>P</i> in <i>n!<sup>2</sup></i> will be <i>2K</i>.
3. Using step 2 calculate number of factors with the standard formula.
For the worst case input of <i>n = 10<sup>6</sup></i>, my c code gives answer in 0.56s.
I guess the complexity is no way greater than <i>O(n lg n)</i>.
But when I submitted the code on the site, I could pass only 3/15 test cases with the verdict on the rest as time limit exceeded.
I need some hint for optimizing this algorithm.

Secondly, I some questions about some code I've been looking at.
1. What does the @staticmethod and @property mean when it is written above a method definition in Python like the following?
@staticmethod
def methodName(parameter):
Class_Name.CONSTANT_VARIABLE = parameter
@property
def methodName(parameter):
Class_Name.CONSTANT_VARIABLE = parameter
2. Another question is in a method definition why would someone set the formal parameter "amount" equal to the constant PERMANENCE_INC in the formal parameter list?
def increasePermanence(self, amount=PERMANENCE_INC):
""" Increases the permanence of this synapse. """
self.permanence = min(1.0, self.permanence+amount)
3. Lastly, and probably the most stupid question is that I'm not really understand what the "self" parameter is in Python in the __init__ method. The previous texts I've been reading seem to just skip over it. Is "self" like the only possible object that can be created by the class or what?
Sorry, for all the questions. I'm aspiring to become great at programming so any information/advice would help. THANKS!

When you click/select an option, the content on main page changes based on the criteria the user clicked on. For example SPA will show only the deals having SPA.

I encountered the problem that occurs when I try to show (un-minimize) the app's window that's visible on the workspace (let's say 'workspace 1') other than the current one ('workspace 2'). The problem is that staying on the workspace to the left of the current one the app's window has negative x coordinate, because window position is counted relative to current workspace. I'd like to get window's position relative to the workspace 1 (not current one) and show it at this point on workspace 2 (the current one).
I'm doing smth like that right now to show window on the current workspace at the position same to the position it was on the previous workspace:
# get desktop size
ws_width, ws_height = gtk.gdk.get_default_root_window().get_size()
# get position relative to current workspace
x, y = window.get_position()
# get position relative to the workspace the window is on
x %= ws_width
y %= ws_height
window.move(x, y)
window.show()
but I don't like this workaround and not sure that this code wouldn't break smth on the desktops other than gnome.
So I'll be grateful for any other solution of the problem as well as information about the situation on other linux desktops (e.g., do they count window position relative to the current workspace as gnome or not). | gtk | position | workspace | null | null | null | open | Get window position relative to the workspace it's placed on in PyGtk

I can estimate quality of the spatio-temporal compression by computing the [syncronized euclidean distance][1] (SED) between compressed and original trajectory and evaluate my algorithm's performance against well-known compression algorithm.
A spatio-temporal algorithm, like mine, reduce the trajectory trying to mantein as much as possible temporal informations. Spatial algorithm (e.g. Douglas-Peucker algorithm) realize the compression refearing only to the spatial characteristics.
What happen now? Considering a spatio-temporal aspect, my algorithm is better than DP. I can assure this by SED measurements.
If I plot the three trajectories (original, mine and DP compressed), the trajectory compressed with DP has a better fitting with the original trajectory. The eye-only mesuraments don't satisfy my need. I need, indeed, an error metric that numerically demonstrate how DP algorithm is better than mine in spatial manner.
So I could write: "Refearing to the spatio-temporal factor, my algorithm is better than DP, because have a SED factor less than DP's SED factor. Alas, simple spatial factor, awards DP algorithm cause his (name of the new metric) is better than mine".

When the user goes to Settings / Security / Device admins and deactivates the admin app, first a dialog is presented "Do you want to deactivate". If the user says "yes", then another small dialog is presented, with the text provided by the application's AdminReceiver in onDisableRequested(). If the user then says "yes", I want to wipe the entire device. How to accomplish this?
I tried everything, searched long for answers, found no real solutions.
What I tried:
- AdminReceiver has a function onDisable(). I tried to wipe the device in that function. However, it appears that onDisable() is called ***after*** the admin has been disabled. Thus the app cannot use the wipeData() function at all (a security exception is thrown). I have also verified that isAdminActive() returns false at that time.
Official documentation does not say this clearly, but it seems that the admin is already disabled when onDisable() is called. Thus we have to wipe the device before that time.
- AdminReceiver has a function onDisableRequested(), which returns CharSequence. I tried to put another alert box in that function. This crashes because an alert box cannot be called from a non-activity context, which seems to be what we have when we are in onDisableRequested().
- AdminReceiver has a function onReceive(), which gets called on any events. In this function, again, we are not in an activity context and cannot present our own dialogs.
- I tried creating another activity from onReceive(). This works; during onReceive() when we get ACTION_DISABLE_ADMIN_REQUESTED, the admin is still active and we can wipe the device. However, the system still presents its own dialog asking the user whether to deactivate the admin. If the user says no to our dialog but yes to the system dialog, the admin will be deactivated and we will have failed to wipe the device.
I tried the following, in my subclass of DeviceAdminReceiver:
@Override
public void onReceive(Context context, Intent intent) {
// detect whether disabling is requested?
if (intent.getAction().equals(ACTION_DEVICE_ADMIN_DISABLE_REQUESTED)) {
confirmWipeDevice(context);
} else {
super.onReceive(context, intent);
}
}
In other words, I do not call super.onReceive() if the action is to disable the admin. The function confirmWipeDevice() shows a different activity with a dialog. This does not show the system dialog for confirming the disabling of my admin app. However, this does not prevent the app from being actually disabled!
It seems that the Android system does the following:
- Send ACTION_DEVICE_ADMIN_DISABLE_REQUESTED to the AdminReceiver
- Proceed with disabling the admin regardless of what the admin app wants to do
- If the user cancels the disabling, fine; if not, the app is disabled. There is no way for the app to refuse being disabled, or to perform the device wipe upon disabling.
The only solution so far is to wipe immediately without confirmation when the user wants to disable the admin app. In other words, I can call getManager().wipeData() immediately in onDisableRequested(). At that time, the admin is still active and this works.

The puzzling part is that it finds the `hibernate-core` artifact in the repository but not the `spring-core` one.
I am thinking that perhaps the Spring jar itself is to blame.
Here is what I have tried so far:
1. Change the Maven repository. I am at work at the moment and we using a Maven Proxy repository. I have tried both local and remote repositories. Problem still exists.
2. Change the Spring version. I have tried different versions of the `spring-core` dependency (`3.0.1-RELEASE, 3.0.3-RELEASE`). Problem still exists.
3. Change the Spring artifact. I have tried the `org.springframework.spring-jdbc` and `org.springframework.security.spring-security-cas-client` artifacts as well. Problem still exists.
4. Verify that it is Spring by trying different artifacts. I have tried 'junit', 'hibernate-core', 'hibernate-validator', 'javaee-web-api'. Some with different versions. Pointing them to either local or remote repositories and they all work.
What I haven't tried yet:
1. Change the version of Gradle
I am using the latest version of Gradle `1.0-rc-3`
2. Try the Maven central repo
Need to configure my proxy but that's my next step. However, I am not too optimistic that it will work.

My ideal situation is that I use CMake to generate the VS2010 project files (there is an option for VS2010 64-bit. I **do not** choose this option) for TagLib. I would like them to be static libraries, so I enable ENABLE_STATIC, and I enable WITH_ASF, and WITH_MP4. I also direct TagLib to zlib using ZLIB_INCLUDE_DIR and ZLIB_LIBRARY (I am linking to the zlib.lib file that I previously built using VS2010). Note, I am using the CMake GUI.
I then open up the generated project files in VS2010 and make three changes to the code so that it build in Visual Studio 2010 without error (*I put the fixes here for anyone else who had the same problem as I*).
**apefooter.cpp** on line 192:
std::bitset<32> flags(static_cast<unsigned long long>(data.mid(20, 4).toUInt(false)));
**mpcproperties.cpp** on line 116:
std::bitset<32> flags = static_cast<unsigned long long>(d->data.mid(8, 4).toUInt(false));
**mpegheader.cpp** on line 171:
std::bitset<32> flags(static_cast<unsigned long long>(data.toUInt()));
I then make then comment out lines 436 and 437 in **mpegfile.cpp**, because [I think it's a bug][2].
// ID3v2Tag(true);
// ID3v1Tag(true);
I then build the project in Release mode. It builds just fine. No errors (although there are a bunch of warnings).
So I have generated **tag.lib**. I then created a test VS2010 project/solution to use TagLib.
This is the only line I use TagLib. Just a test, mind you.
TagLib::MPEG::File a("tests/other/blank.mp3");
- I added `TAGLIB_STATIC` to the preprocessor options (*Property Pages > Configuration Properties > C/C++ > Preprocessor > Preprocessor Definitions*) for all configurations (both Release and Debug builds)
- I added every single darn header directory to *Property Pages > Configuration Properties > C/C++ > General > Additional Include Directories*
- And finally I added zlib.lib and tag.lib to the additional dependencies (*Property Pages > Configuration Properties > Linker > Input > Additional Dependencies*) IN THAT ORDER
