  • How a JIT compiler helps performance of applications?

    - by igorgue
    I just read that Android has a 450% performance improvement because it added a JIT compiler, I know what JIT is, but I don't really understand why is it faster than normal compiled code? or what's the difference with the older approach from the Android platform (the Java like run compiled bytecode). Thanks!

  • Server -> Desktop Push API

    - by Rich Anderson
    Hi I am looking for solution which can push automatically a certain event (let's say RSS message) realtime to a desktop user. A toolbar app or a desktop (growl like) will be super for this push. I have looked at few options but cannot find much info on these kind of apps. I have looked at conduit - it sucks as there is lot of other fancy options which I am not interested in offering to users. Please let me know. Thanks.

  • Drupal 7 Forms API Conditional Logic not working in IE

    - by Francis Yaconiello
    I have a drupal 7 form with a bunch of fields: $form['account_type'] = array( '#title' => t('Utility Account Type'), '#type' => 'select', '#options' => necp_enrollment_administration_portal_account_type_options(), '#required' => TRUE, '#default_value' => isset($form_state['values']['account_type']) ? $form_state['values']['account_type'] : '', ); // Should show if account_type = 1 $form['home_wrapper'] = array( '#type' => 'fieldset', '#states' => array( 'visible' => array( ':input[name="account_type"]' => array('value' => 1), ), ), ); $form['home_wrapper']['first_name_1'] = array( '#title' => t('Primary Account First Name'), '#type' => 'textfield', '#default_value' => isset($form_state['values']['first_name_1']) ? $form_state['values']['first_name_1'] : '', '#states' => array( 'required' => array( ':input[name="account_type"]' => array('value' => 1), ), ), ); $form['home_wrapper']['last_name_1'] = array( '#title' => t('Primary Account Last Name'), '#type' => 'textfield', '#default_value' => isset($form_state['values']['last_name_1']) ? $form_state['values']['last_name_1'] : '', '#states' => array( 'required' => array( ':input[name="account_type"]' => array('value' => 1), ), ), ); // Should show if account_type = 2 $form['business_wrapper'] = array( '#type' => 'fieldset', '#states' => array( 'visible' => array( ':input[name="account_type"]' => array('value' => 2), ), ), ); $form['business_wrapper']['company_name'] = array( '#title' => t('Company/Organization'), '#type' => 'textfield', '#default_value' => isset($form_state['values']['company_name']) ? $form_state['values']['company_name'] : '', '#states' => array( 'required' => array( ':input[name="account_type"]' => array('value' => 2), ), ), ); In Firefox/Chrome/Opera all versions this form behaves as it should. However in all versions of IE the form initializes with display:none; style on all of the conditional fields regardless of what the value in account_type is. Changing the selected option of account_type does not effect the hidden status. Any tips on debugging this form would be awesome. Notes: I am not much of a Drupal developer, I inherited this site. Just trying to iron out the last couple bugs so we can go live there are more fields than are listed above, I just gave you some of the applicable ones so that you could get the gist of how my forms were setup current url for the form in development: https://northeastcleanpower.com/enroll_new I'm using http://www.browserstack.com/ to debug IE 7 - 10pp4 (I think we only have to support 8 and up though) I've also tried: ':select[name="account_type"]' => array('value' => 1), '#edit-account-type' => array('value' => 1),

  • Display custom title bar in XML

    - by Casebash
    In Android documentation describing "Configuring General Window Properties", it is suggested that specifying properties via XML is preferable whenever possible. As an example, instead of setting Window.FEATURE_NO_TITLE with requestWindowFeature, they set it to @android:style/Theme.NoTitleBar. Is there a similar way to set a custom title bar to be used in the XML?

  • Wordpress API: Add / Remove Tags on Posts

    - by st4ck0v3rfl0w
    I know it seems like a simple operation, but I can't find any resource or documentation that explains how to programmatically add and remove tags to a post using the post ID. Below is a sample of what I'm using, but it seems to overwrite all the other tags... function addTerm($id, $tax, $term) { $term_id = is_term($term); $term_id = intval($term_id); if (!$term_id) { $term_id = wp_insert_term($term, $tax); $term_id = $term_id['term_id']; $term_id = intval($term_id); } $result = wp_set_object_terms($id, array($term_id), $tax, FALSE); return $result; }

  • How to show subscribed Gmail calendars in Windows 8 calendar app

    - by flooooo
    Is it possible to show my subscribed calendars on Gmail in the Windows 8 calendar app like I'm used to do on my Windows Phone? I think - but am not sure about that - that it uses the mobile API. When I try to configure it via http://m.google.com/sync on my Windows Phone I can see the client "WindowsMail" but cannot add or configure shared calendars as for my smartphone. Is there currently a possibility to achieve this or do we need to wait until they get that enabled for us?

  • Deleting a Collection with NHibernate Using the Criteria API

    - by lomaxx
    I think I know what the answer to this question is probably going to be, but I thought I'd go ahead and ask it anyway. It appears that within NHibernate if I do something like this: IList<Customer> customers = Session.CreateCriteria(typeof(Customer)) .Add(Restrictions.Eq("Name", "Steve") .List<Customer>(); And I want to then delete that list of customers. From what I can tell the only way to do it is like this: foreach(var customer in customers) { Session.Delete(customer); } But what I'm wondering is if there's any way I can just go: Session.Delete(customers); And delete the entire collection with a single call?

  • Creating a Custom Compound Button Bar

    - by vijay
    I have to create a custom compound button bar control in Android like the one here. To create a button bar like this, I am thinking of extending a LinearLayout and add my buttons to it. The buttons have a black background but with a gradient fill; I am not keen on using PNGs since the color of the buttons can change at runtime. How can I get similar effect in Android? Thanks.

  • Endianness and C API's: Specifically OpenSSL.

    - by Hassan Syed
    I have an algorithm that uses the following OpenSSL calls: HMAC_update() / HMAC_final() // ripe160 EVP_CipherUpdate() / EVP_CipherFinal() // cbc_blowfish These algorithm take a unsigned char * into the "plain text". My input data is comes from a C++ std::string::c_str() which originate from a protocol buffer object as a encoded UTF-8 string. UTF-8 strings are meant to be endian neutrial. However I'm a bit paranoid about how OpenSSL may perform operations on the data. My understanding is that encryption algorithms work on 8-bit blocks of data, and if a unsigned char * is used for pointer arithmetic when the operations are performed the algorithms should be endian neutral and I do not need to worry about anything. My uncertainty is compounded by the fact that I am working on a little-endian machine and have never done any real cross-architecture programming. My beliefs/reasoning are/is based on the following two properties std::string (not wstring) internally uses a 8-bit ptr and a the resulting c_str() ptr will itterate the same way regardless of the CPU architecture. Encryption algorithms are either by design, or by implementation, endian neutral. I know the best way to get a definitive answer is to use QEMU and do some cross-platform unit tests (which I plan to do). My question is a request for comments on my reasoning, and perhaps will assist other programmers when faced with similar problems.

There are two identical questions on stackoverflow: here and here. But they do not explain what the initial issue could be and they do not work for me. E.g. changing to launchMode singleTop is not appropriated for me and it should work without changing launchMode according to the official docs (see Invoking the search dialog). Nevertheless I also tried to add the following flags to notificationIntent Intent.FLAG_ACTIVITY_CLEAR_TOP | PendingIntent.FLAG_UPDATE_CURRENT but the problem remains the same.

  • Problem with sending out variable to serial port using api JAVA

    - by sjaakensjon
    We are developing a java program for school. But we are experiencing problems with sending out a variable created by 3 sliders. The idea is that we have 3 sliders. One slider for every color. Red green and blue. The variable has to have a value between 0 and 255. Everytime the value of the slider changes is has to send a variable for the channel, that value is 1, 2 ,3. And after that it has to send the value of the slider through the serial port. Could you please help us out by creating an example program? Below is our code so far. Thanks in advance. Sjaak package main; import javax.swing.*; import javax.swing.event.*; import java.awt.*; import app.Com; import app.Parameters; public class menu{ JSlider sliderblauw; JLabel hoeveelblauw; JLabel blauw; JLabel rood; JSlider sliderrood; JLabel hoeveelrood; JLabel groen; JLabel hoeveelgroen; JSlider slidergroen; public menu(){ Frame venster = new JFrame("Color control"); JPanel blauwinstel = new JPanel(); ((JFrame) venster).setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); venster.setSize(500, 500); venster.setVisible(true); sliderblauw = new JSlider(JSlider.VERTICAL, 0, 255, 0); sliderblauw.addChangeListener(new veranderingblauw()); hoeveelblauw = new JLabel ("0"); blauwinstel.add(sliderblauw); blauwinstel.add(hoeveelblauw); venster.add(blauwinstel, BorderLayout.WEST); sliderblauw.setMajorTickSpacing(10); sliderblauw.setPaintTicks(true); JPanel roodinstel = new JPanel(); sliderrood = new JSlider(JSlider.VERTICAL, 0, 255, 0); sliderrood.addChangeListener(new veranderingrood()); hoeveelrood = new JLabel ("0"); roodinstel.add(sliderrood); roodinstel.add(hoeveelrood); venster.add(roodinstel, BorderLayout.EAST); sliderrood.setMajorTickSpacing(10); sliderrood.setPaintTicks(true); JPanel groeninstel = new JPanel(); slidergroen = new JSlider(JSlider.VERTICAL, 0, 255, 0); slidergroen.addChangeListener(new veranderinggroen()); hoeveelgroen = new JLabel ("0"); groeninstel.add(slidergroen); groeninstel.add(hoeveelgroen); venster.add(groeninstel, BorderLayout.CENTER); slidergroen.setMajorTickSpacing(10); slidergroen.setPaintTicks(true); } public class veranderingblauw implements ChangeListener{ public void stateChanged(ChangeEvent ce){ int value = sliderblauw.getValue(); String waarde_blauw = Integer.toString(value); hoeveelblauw.setText(waarde_blauw); }} public class veranderingrood implements ChangeListener{ public void stateChanged(ChangeEvent ce){ int value = sliderrood.getValue(); String waarde_rood = Integer.toString(value); hoeveelrood.setText(waarde_rood); }} public class veranderinggroen implements ChangeListener{ public void stateChanged(ChangeEvent ce){ int value = slidergroen.getValue(); String waarde_groen = Integer.toString(value); hoeveelgroen.setText(waarde_groen); }} public static void main( String[] args) { new menu(); } }

  • Some facebook friends' birthdays returning as null but I have the correct API permissions

    - by Andrei Radulescu
    I'm tring to get my friends' birthdays in my app and some of them are null. I thought that those people don't have a birthday set, but they actually do. My fql query is: SELECT uid,name,birthday_date FROM user WHERE uid IN (SELECT uid2 from friend where uid1=me()) My app has the "friends_birthday" permission set. I also tried with "birthday" instead of "birthday_date". Same result. I imagine that this happens because they opted out somehow, but I don't know how. Is there an alternate solution to actually get their birthdays from facebook? Thanks!
