I am wondering, is there any way in core graphics where I can take the shape I just created and stretch it both horizontally and vertically so that it fits perfectly in its views frame? IE so I don't have to manually go into all my points and values and write them in terms of the view bounds? I know for this shape it wouldn't be that difficult, but I have some more complex shapes that are more time consuming that I'd rather avoid doing that... | iphone | ios | cocoa-touch | core-graphics | null | null | open | Stretch Drawn Shape to fit Frame?

When I click the button the partial postback occurs and the textbox has the expected value of 'Button Clicked'
When I change the dropdown the partial postback occurs, however the textbox does not have the expected value of 'Dropdown changed' because the code in ddlTest_SelectedIndexChanged is never hit (breakpoint placement on that line of code also never hits)
In the larger scope of my project this is the crux of the problem and I can't determine why this event is never hit (the core problem is when I load a dynamic user control, the data in the control is bound correctly, but then is overridden with the pre-post data after the user control is loaded - the override is occurring somewhere in the post back events). It appears to me it has something to do with the binding of the dropdown and where it happens in the page cycle, but I haven't been able to nail anything down, nor come up with google solutions.
One odd thing I did notice when looking at the post in Firebug - the EVENTTARGET value for the dropdown was the UniqueId of the dropdown, but the EVENTTARGET value is empty for the button click. My brain is thinking there is some connection here.
FYI - I have come up with a work around that seems to do the trick. I set autopostback on dropdown to false, and using jQuery I assign the change event on the dropdown to fire the button click - which causes the postback and fires btn_click event in code. | drop-down-menu | updatepanel | partial-postback | null | null | null | open | Dropdown autopost inside updatepabel never enters code behind SelectedIndexChanged event

My app keeps force closing if I try to run a query based on my 2nd of the two URIs and logcat gives me the error "failed to find provider for..."
My two URIs are defined as follows in the ContentProvider class:
public static final Uri CONTENT_ACCOUNT_URI = Uri.parse("content://com.vanhlebarsoftware.kmmdroid.kmmdprovider/account");
public static final Uri CONTENT_SCHEDULE_URI = Uri.parse("content://com.vanhlebarsoftware.kmmdroid.kmmprovider/schedule");
My provider is declared as follows in the manifest:
`<provider android:name=".KMMDProvider"android:authorities="com.vanhlebarsoftware.kmmdroid.kmmdprovider"></provider>`
Finally in my home screen widget I am calling the provider like this, which works just fine if I call it with CONTENT_ACCOUNT_URI but fails when I used the CONTENT_SCHEDULE_URI:
c = context.getContentResolver().query(KMMDProvider.CONTENT_SCHEDULE_URI, null, null, null, null);
Right now I need these two distinct URIs but in the future I might need more, if having them all defined in a single ContentProvider class is not the best way to go then how else should I do it? Have a separate ContentProvider for each URI that I need? That just doesn't seem to make much sense to me and seems like it would be a lot of extra code. | android | android-widget | null | null | null | null | open | Is it possible to have more than one Content_URI inside a provider?

For example, I'd guess that not every assertion needs to have a failure message defined, namely, when it's quite clear what the expected outcome of the test is supposed to be. But there are those instances when you might want to test a few aspects of an object after doing a single action, meaning that you may have a couple assertions listed in one test method. Should each assertion in that scenario have a descriptive failure message, so that it's easy to see why the test method might have failed at a given point?

I am running it in Windows 64-bit, but using 32-bit Python.
Part of the program involves downloading a lot of data (up to several gigabytes), and then proceeding to process the data. The software has been relatively stable for a while, but we just introduced a new data source that substantially adds to the quantity of data downloaded. I believe this is when the bug has started occurring. Running the exact same test case over and over again, I get errors at what seems to be random places. Here are two of the error messages I've seen so far:
IOError: [Errno 13] Permission denied: "[filename]"
and
WindowsError: [Error 32] The process cannot access the file because it is being used by another process: "[filename]"
I will give out more information if it is needed. Again, I have only seen this error recently with the introduction of a new data source, so I think it has something to do with the volume of data. Does anybody have an idea what would be causing this?

I've generated an MVC3 app using EF4.1 from an existing database and the list in the MVC3 view (based on a SQL View) shows different results to the SQL View viewed in SQL manager. Specifically, fields from a joined table seem to not get updated between multiple hits on the main table.
The funny thing is: If I capture the sql that intellisense shows for the db.myViewClass.ToList() call and paste that into SQL manager, it gives the right results!
I've also created a mini test app and that works fine. So far I can't see how the test app differs from my main app which fails.
I'm frustrated that I can't step in to the code to see what's happening in db.myViewClass.
Any bright ideas anyone?

i have the following classes. First my PagerAdapter:
package com.example.tab1;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class SectionsPagerAdapter extends FragmentPagerAdapter {
static final int NUM_ITEMS = 3;
private final FragmentManager mFragmentManager;
private Fragment mFragmentAtPos0;
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
mFragmentManager = fm;
}
@Override
public Fragment getItem(int position) {
Bundle args = new Bundle();
mFragmentAtPos0= new testFragment();
args.putInt(testFragment.ARG_SECTION_NUMBER, position + 1);
mFragmentAtPos0.setArguments(args);
return mFragmentAtPos0;
}
@Override
public int getItemPosition(Object object) {
return 0;
}
@Override
// liefert die Anzahl der Tabs
public int getCount() {
return NUM_ITEMS;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
// return getString(R.string.title_section1).toUpperCase();
// return
// Resources.getSystem().getString(R.string.title_section1).toUpperCase();
return "Suche".toUpperCase();
case 1:
// return getString(R.string.title_section2).toUpperCase();
// return
// Resources.getSystem().getString(R.string.title_section2).toUpperCase();
return "Ergebnis".toUpperCase();
case 2:
// return
// Resources.getSystem().getString(R.string.title_section3).toUpperCase();
return "Optionen".toUpperCase();
}
return null;
}
}
Secondly my My DatePickerFragment:
package com.example.tab1;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class DatePickerFragment extends DialogFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public static DatePickerFragment newInstance() {
DatePickerFragment f = new DatePickerFragment();
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//Log.d("DEBUG", "onCreateView");
return inflater.inflate(R.layout.datepickerfrag, container, false);
}
}
And Finally my MainActivity, where i activate the change in the method onClickSearch, which is a method from an interface in my first Fragment, which is shown when the app is started.
package com.example.tab1;
import android.app.ActionBar;
import android.app.FragmentTransaction;

*/
SectionsPagerAdapter mSectionsPagerAdapter;
/**
* The {@link ViewPager} that will host the section contents.
*/
ViewPager mViewPager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create the adapter that will return a fragment for each of the three
// primary sections
// of the app.

getSupportFragmentManager());
// Set up the action bar.
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
// When swiping between different sections, select the corresponding
// tab.
// We can also use ActionBar.Tab#select() to do this if we have a

mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
// For each of the sections in the app, add a tab to the action bar.
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
// Create a tab with text corresponding to the page title defined by
// the adapter.
// Also specify this Activity object, which implements the
// TabListener interface, as the
// listener for when this tab is selected.
actionBar.addTab(actionBar.newTab()
.setText(mSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
}
actionBar.selectTab(actionBar.getTabAt(0));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
/*

public void OnclickSearchS() {
android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.pager,DatePickerFragment.newInstance());
ft.commit();
//mViewPager.setCurrentItem(1);
}
public void onTabUnselected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
}
public void onTabSelected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
// When the given tab is selected, switch to the corresponding page in
// the ViewPager.
mViewPager.setCurrentItem(tab.getPosition());
}
public void onTabReselected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
}
/**
* A {@link FragmentPagerAdapter} that returns a fragment corresponding to
* one of the primary sections of the app.
*/
}
When the application is running, i push the button the first time and nothing happens, when i do this again secondly, i see an empty fragment and get an error afterwards:

| replace | android-fragments | android-viewpager | null | null | null | open | Replacing Fragments correctly within ViewPager
===
by now i'am totally desperated. Whole day i'am trying to replace a fragment within a view, but don't succeed yet.
i have the following classes. First my PagerAdapter:
package com.example.tab1;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class SectionsPagerAdapter extends FragmentPagerAdapter {
static final int NUM_ITEMS = 3;
private final FragmentManager mFragmentManager;
private Fragment mFragmentAtPos0;
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
mFragmentManager = fm;
}
@Override
public Fragment getItem(int position) {
Bundle args = new Bundle();
mFragmentAtPos0= new testFragment();
args.putInt(testFragment.ARG_SECTION_NUMBER, position + 1);
mFragmentAtPos0.setArguments(args);
return mFragmentAtPos0;
}
@Override
public int getItemPosition(Object object) {
return 0;
}
@Override
// liefert die Anzahl der Tabs
public int getCount() {
return NUM_ITEMS;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
// return getString(R.string.title_section1).toUpperCase();
// return
// Resources.getSystem().getString(R.string.title_section1).toUpperCase();
return "Suche".toUpperCase();
case 1:
// return getString(R.string.title_section2).toUpperCase();
// return
// Resources.getSystem().getString(R.string.title_section2).toUpperCase();
return "Ergebnis".toUpperCase();
case 2:
// return
// Resources.getSystem().getString(R.string.title_section3).toUpperCase();
return "Optionen".toUpperCase();
}
return null;
}
}
Secondly my My DatePickerFragment:
package com.example.tab1;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class DatePickerFragment extends DialogFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public static DatePickerFragment newInstance() {
DatePickerFragment f = new DatePickerFragment();
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//Log.d("DEBUG", "onCreateView");
return inflater.inflate(R.layout.datepickerfrag, container, false);
}
}
And Finally my MainActivity, where i activate the change in the method onClickSearch, which is a method from an interface in my first Fragment, which is shown when the app is started.
package com.example.tab1;
import android.app.ActionBar;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.Menu;
public class MainActivity extends FragmentActivity implements
ActionBar.TabListener,testFragment.ButtonListenerS{
/**
* The {@link android.support.v4.view.PagerAdapter} that will provide
* fragments for each of the sections. We use a
* {@link android.support.v4.app.FragmentPagerAdapter} derivative, which
* will keep every loaded fragment in memory. If this becomes too memory
* intensive, it may be best to switch to a
* {@link android.support.v4.app.FragmentStatePagerAdapter}.
*/
SectionsPagerAdapter mSectionsPagerAdapter;
/**
* The {@link ViewPager} that will host the section contents.
*/
ViewPager mViewPager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Create the adapter that will return a fragment for each of the three
// primary sections
// of the app.
mSectionsPagerAdapter = new SectionsPagerAdapter(
getSupportFragmentManager());
// Set up the action bar.
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
// When swiping between different sections, select the corresponding
// tab.
// We can also use ActionBar.Tab#select() to do this if we have a
// reference to the
// Tab.
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
// For each of the sections in the app, add a tab to the action bar.
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
// Create a tab with text corresponding to the page title defined by
// the adapter.
// Also specify this Activity object, which implements the
// TabListener interface, as the
// listener for when this tab is selected.
actionBar.addTab(actionBar.newTab()
.setText(mSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
}
actionBar.selectTab(actionBar.getTabAt(0));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
/*
* Implementierung des "Suchbuttons" (non-Javadoc)
* Interaktion zwischen testFragment und MainActivity
*/
public void OnclickSearchS() {
android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.pager,DatePickerFragment.newInstance());
ft.commit();
//mViewPager.setCurrentItem(1);
}
public void onTabUnselected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
}
public void onTabSelected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
// When the given tab is selected, switch to the corresponding page in
// the ViewPager.
mViewPager.setCurrentItem(tab.getPosition());
}
public void onTabReselected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
}
/**
* A {@link FragmentPagerAdapter} that returns a fragment corresponding to
* one of the primary sections of the app.
*/
}
When the application is running, i push the button the first time and nothing happens, when i do this again secondly, i see an empty fragment and get an error afterwards:

looping ... checks if (globalVar > 0)
looping ... execute all four bytecode commands of "test.globalVar--;"
execute test.globalVar--;

if change == "next": mod = mdelta
elif change == "prev": mod = -mdelta
year, month = (now+mod).timetuple()[:2]
# init variables

month_days = cal.itermonthdays(year, month)
nyear, nmonth, nday = time.localtime()[:3]

# each day tuple will contain list of entries and 'current' indicator

I was told server side scripting language is required. To be honest, I have basic skills in coding, and I am completely stumped by this task. Any help (explained in simple terms please) would be greatly appreciated.

Some of my mapper tasks are returning code 143. I'd love to drop a breakpoint on System.exit() and see who's calling this why, but I have to get the debugger running on that mapper.
I can get the task tracker up in the debugger by modifying my bin/hadoop script and remotely connecting to localhost:5000:
...
elif [ "$COMMAND" = "tasktracker" ] ; then
CLASS=org.apache.hadoop.mapred.TaskTracker
HADOOP_OPTS="$HADOOP_OPTS $HADOOP_TASKTRACKER_OPTS"
# TBMark!
HADOOP_OPTS="$HADOOP_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,address=5000,server=y,suspend=n"
...and I can get the first mapper (or by a minor tweak, reducer) into Eclipse by adding this into my conf/mapred-site.xml and remotely connecting to localhost:5001:
<property>
<name>mapred.map.child.java.opts</name>
<value>-Xdebug -Xrunjdwp:transport=dt_socket,address=5001,server=y,suspend=y</value>
</property>
My problem is that the failure happens at random and not on the first mapper.
Unsatisfactory ideas that come to mind include:
1. Somehow replace System.exit() with my own method that does a stack trace. (How does one hook a system call?)
2. Just keep trying to debug the mappers one by one and run each one to completion before debugging the next. (It *might* work...)
3. Track down every last place in hadoop that calls System.exit() and write a distinct signature to a log. (*Yuck*)
4. Make the debugger port number variable such that, if I can guess which one is going to fail and the delay doesn't make the bug go away, I can attach to that jvm and debug it. (Many if's, and I don't know any way to make this variable in the .xml file.)

My Question is this, will this negatively affect the page from an SEO perspective ?
Please note the following :
- I will serve non javascript users a notice and essentially a single column 'print' stylesheet, with all of the sites functionality hidden, so thats not a concern.

One my scripts actually changes the image of a div container at mouse over function, function is currently fine but make it feel a little beautiful I want to add transition affects to it either through fade in fade out functions or through animate but am unable to work it out with both. I searched over internet but here i am unable to relate those examples to mind here.
I just want to know where can I insert fade in fade out or animate function in this code, to give it a transitioning effect:
$(document).ready(function () {
$(".thumb").hover(function () {

- Session is start.
- $id is set to a number (tournament ID number).
Result:
- User SESSION vars are reset with the ID number and the ID number's respective user data. Essentially logging the user in under a different account.
Troubleshooting:
- Renaming $id to $tid stops the glitch.
- Not starting the session ("session_start()") stops the glitch.
Thought Process:
- $id must overwrite similar variable which is inside a block which contains:
`if(isset( $_SESSION['someVar'] )) {
$id = "some Value";
}`
Since $id is only overwritten when session is started.
The Problem:
- There is no block of code that uses that syntax.
Here's the call stack.
jointourney.php
<?
session_start();
$id = (isset($_POST['id'])) ? $_POST['id'] : false;
include("html.php");
?>

<?

}
}

As you see, there is absolutely no place where jointourney.$id can overwrite - since there is no other variable called $id being used.

Using another question as reference, I tried to adapt the framework of using a QLabel and painting to it (the process overall seems overly complicated).
I started by making a member in the dialog box's class:
QLabel* label;
In the constructor of the dialog box:
label = new QLabel(this);
label->setGeometry(20, 50, 50, 100);
Just to try and make it work, I gave the dialog box a button to make the "rectangle" created with the label appear on the widget. I connected the "pressed" signal of this button to a slot which does the following:
QPixmap pixmap(50, 100);
pixmap.fill(QColor("transparent"));
QPainter painter(&pixmap);
painter.setBrush(QBrush(Qt::black));
painter.drawRect(20, 50, 50, 100);

update();
Unfortunately, nothing appears in the widget when I press the button. What am I missing here?

Has anyone got any clue as to what this could be? I would also be very happy with hints on how to further debug this, because I don't know where to look next..
Thanks in advance!

A little explanation. I'm using one model to populate the: text, controls, default values (select lists), and values saved. I'm using the other ViewModel to only return the: value, dataid, and ctrltypeid. What has been commented out is the code (ex: Html.TextBoxFor) that is causing the postback ViewModel to be unpopulated. The working code (ex: Html.TextBox) does as expected. So I'm wondering what do I have to do to the commented code to make it work like the uncommented code. Is there actually anything I *can* do?

This however does not rotate as I expect it to. Maybe I am completely wrong and need a push in the right direction. :-) Thanks.

I have an ImageButton and want to scale the button in different sizes which means an image is not the right choice. So I was thinking of an ImageButton with a custom Shape as source.
I want the button to look like this:

I started with this, but got stuck with the rotate stuff:

Correct me if I am wrong.
Second, I don't manage to make each column to work well and sometimes it's just linking to the same page, no matter which option I choose as well to another problem that there is no reaction to my choice, like I didn't do anything even if I really chose something from the menu.
Do you know what can be the problem? Is it a bad idea to do it with JavaScript? Would you make it with PHP? I also thing that the code is maybe too long.
This is the example for my problem - [link][1]

I am having problem with asp:wizard. I have a textbox within a repeater in step1 of asp:wizard. The user enters values in the textbox. Based on this value data has to be populated in another repeater in step2 of wizard. But on clicking the next button, I dont get the next repeater populated depending on the textbox value of the first repeater.

Internally, a function-based index seems to generate a hidden table column (of type varchar2(4000), since my function returns a varchar2), and indexes that. That works fine when the index is used, but sometimes we have to do a full table scan using the function as a filter, and in that case I see a performance degradation by a factor of 6. Seems in that case, Oracle does not use the hidden column, but recomputes the function for each row, make the query CPU-bound instead of IO-bound.
Is there a way to make Oracle use that hidden column also for filtering? I wonder if I'm missing some rewrite options or something along those lines.
If not, I'll have to define the column myself and using a trigger to keep it up to date. I'd prefer using the function-based index for transparency and easier maintanance. | oracle | index | user-defined-functions | null | null | null | open | Function-based index when not using index access

Is there a way to make Oracle use that hidden column also for filtering? I wonder if I'm missing some rewrite options or something along those lines.
If not, I'll have to define the column myself and using a trigger to keep it up to date. I'd prefer using the function-based index for transparency and easier maintanance. | 0 |

On the server I want to return something like:

callback: function() {

When returned to the browser callback function should fire. I want the server to return the callback so I can use the same JavaScript code and have it respond accordingly to the server response.
Would I need to change the dataType to script? However I thought this was just for loading .js files, not blocks of code.
Any help appreciated.

The above code works fine from technical point of view but I have a problem somewhere in handling the return values of the different instances of the called external process. In particular it happens that the return value associated to a certain instance is attributed to a different one randomly.
For example suppose 4 different instances of the external process are called with the arguments meas1, meas2, meas3 and meas4 respectively and suppose that meas1, meas2 and meas3 are successfully processed and that for meas4 the process fails. In situation like that my code mix up the return vales giving success for meas1, meas3, and meas4 and failure for meas2 or success for meas1, meas2, meas4 and failure for meas3.
Any idea on why this can happens?
Any help is really welcome.

So when in my timezone is for example 9:00 and i set alarm on 10:00, and switch timezone (+1 hours) where actual time is 10:00, android reschedule my alarm to 11:00, as expected. This is very fine, however, i didn't found also anything in docs...
Anybody has more official information? Thx | android | timezone | alarmmanager | dst | null | null | open | Android AlarmManager and DST/Timezone/Time change?

I'm coding an alarm clock application, and i would like to know what happens, when I set some alarm with AlarmManager for example at time 2:59am (this is not time of my alarm, this is only time WHEN i set some alarm), and at 3:00am there will be automatic time change from summer time to winter (DST). What happens with my scheduled alarm? I found nothing in docs, and it's not so easy to test, at least I must change dates and wait few hours...I'm not so patient ;)

The site/app should on one hand allow the user to browse and investigate different products and information in a stateless webpage allowing caching of these pages, but should on the other hand have the functionality to let the user login and access different content acquired using sessions.
Thus for a subset of my routes I want session state activated, while for the complementary subset (the rest of my routes) express sessions should be deactivated, allowing caching of these pages.
How can I do this in a clean way?
Say the routes for which I want to activate sessions are '/kj%C3%B8p', '/bibliotek' and '/register'.
I tried something like
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
var pageName = 'somepage';
var oneYear = 1000*60*60*24*365;
app.use(express.bodyParser());
app.use('/kj%C3%B8p', express.cookieParser());
app.use('/kj%C3%B8p', express.session({key: pageName, secret: 'someCode', store: new RedisStore, cookie: {path:'/', maxAge: (5*oneYear), httpOnly: true}}));
app.use('/bibliotek', express.cookieParser());
app.use('/bibliotek', express.session({key: pageName, secret: 'someCode', store: new RedisStore, cookie: {path: '/', maxAge: (5*oneYear), httpOnly: true}}));

app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
but this regenerates the session object for each of the three routes, and seems quite messy. Any tips? | session | routes | express | connect | null | null | open | Express.js sessions activated on a subset of routes

My LoginController checks the user/pass combination and sets a property on the $rootScope reflecting this:
function LoginController($scope, $location, $rootScope) {
$scope.attemptLogin = function() {
if ( $scope.username == $scope.password ) { // test
$rootScope.loggedUser = $scope.username;
$location.path( "/main" );
} else {
$scope.loginError = "Invalid user/pass.";
}
}
Everything works, but if I access `http://localhost/#/main` I end up bypassing the login screen. I wanted to write something like "whenever the route changes, if $rootScope.loggedUser is null then redirect to /login"
...
... wait. Can I listen to route changes somehow? I'll post this question anyway and keep looking. | angularjs | null | null | null | null | null | open | angular.js: Redirecting to a certain route based on condition

I'm writing a small Angular.js app that has a login view and a main view, configured like so:
$routeProvider
.when('/main' , {templateUrl: 'partials/main.html', controller: MainController})
.when('/login', {templateUrl: 'partials/login.html', controller: LoginController})
.otherwise({redirectTo: '/login'});
My LoginController checks the user/pass combination and sets a property on the $rootScope reflecting this:
function LoginController($scope, $location, $rootScope) {
$scope.attemptLogin = function() {
if ( $scope.username == $scope.password ) { // test
$rootScope.loggedUser = $scope.username;
$location.path( "/main" );
} else {
$scope.loginError = "Invalid user/pass.";
}

For example,
t <- seq(0, 1, len = 100)
x <- c(sin(2*pi*t*2.3) + 0.25*rnorm(length(t)),NA, cos(2*pi*t*2.3) + 0.25*rnorm(length(t)))
I am using chebyshev filter: `cf1 = cheby1(5, 3, 1/44, type = "low")`
then
z <- filter(cf1, x) # apply filter
This one doesn't work and i already tried na.rm=T, it seems there's no such argument.
Thank you guys.
