Cordova / Ionic - Multiple Dex Issue with "Facebook Connect" and "LocalNotification" plugins.

Had a problem with Cordova / Ionic today: Multiple dex files define Landroid/support/annotation/AnimRes;

After some hours of reading and testing found solution that worked for me in following configuration:

com.phonegap.plugins.facebookconnect 0.11.0 "Facebook Connect"
de.appplant.cordova.plugin.local-notification 0.8.2-dev "LocalNotification"

Fix was quite simple (after a couple of hours :) :


-   <framework custom="true" src="platforms/android/FacebookLib">
+   <framework src="">
+   <framework src="">


-   <dependency id="cordova-plugin-android-support-v4">
+   <framework src="">

PS: de.appplant.cordova.plugin.local-notification will install cordova-plugin-android-support-v4 - you can remove it after this with ionic plugin remove cordova-plugin-android-support-v4

backbone.js + underscore.js + ??? = good localization

Starting a localization process for one of projects. Currently looking for localization of backbone and underscore parts. i18n plugin from require.js seems to do almost all that I need, but... there is a storage feeling that everything is too simple... Looking around on the web found some frameworks, projects but they don't offer anything that I can not get with a plain and simple require.js i18n... Strange... Someone passed through same feeling before? What was the result? :)

npm + grunt + bower + grunt-bower-task

Maybe this will help someone... In any case - I'm keeping this KB mostly for myself :)

Since I prefer following structure for my node.js (and backbone / underscore) projects:

     lib/ - here will go all libs/frameworks
     app/ - here will go all JS application files

1) Sample package.json:

  "name": "test",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app.js"
  "dependencies": {
    "express": "3.*",
    "bower": "*"
  "devDependencies": {
    "grunt": "^0.4.5",
    "grunt-bower-task": "^0.4.0"

2) Sample Gruntfile.js:

module.exports = function(grunt) {
  var path = require('path');

    pkg: grunt.file.readJSON('package.json'),
    bower: {
      install: {
        options: {
          targetDir: './public',
          layout: function(type, component, source) {
            var renamedType = type;
            if (type == 'js') renamedType = 'js/lib';
            else if (type == 'js/map') renamedType = 'js/lib';
            else if (type == 'js/lang') renamedType = 'js/lib/lang';
            else if (type == 'css') renamedType = 'css';
            else if (type == 'css/img') renamedType = 'css';
            return path.join(renamedType);;
          install: true,
          verbose: false,
          cleanTargetDir: false,
          cleanBowerDir: false,
          bowerOptions: {}


  // Default task(s).
  grunt.registerTask('default', ['bower']);

3) Sample bower.json

  "name": "test",
  "version": "0.0.0",
  "moduleType": [
  "authors": [
    "Viktor Yarmak "
  "license": "MIT",
  "ignore": [
  "dependencies": {
    "requirejs": "*",
    "jquery": "1.*",
    "backbone": "*",
    "underscore": "*",
    "bootstrap": "*",
    "font-awesome": "*",
    "backbone-validation": "*",
    "backbone.paginator": "*",
    "fuelux": "*",
    "moment": "*",
    "chosen": ""
  "exportsOverride": {
    "requirejs": {
      "js": "require.js"
    "jquery": {
      "js": "dist/jquery*.js",
      "js/map": "dist/jquery*.map"
    "jquery-1.*": {},
    "backbone": {
      "js": "backbone.js"
    "underscore": {
      "js": "underscore*.js",
      "js/map": "underscore*.map"
    "bootstrap": {
      "js": "dist/js/bootstrap*.js",
      "js/map": "dist/js/bootstrap*.map",
      "fonts": "dist/fonts/*",
      "css": "dist/css/*"
    "font-awesome": {
      "css": "css/*",
      "fonts": "fonts/*"
    "backbone-validation": {
      "js": "dist/*.js"
    "backbone.paginator": {
      "js": "lib/*.js"
    "fuelux": {
      "js": "dist/js/*.js",
      "fonts": "dist/fonts/*",
      "css": "dist/css/*"
    "chosen": {
      "js": "chosen.jquery*.js",
      "css/img": "chose*.png",
      "css": "chosen*.css"
    "moment": {
      "js": "moment.js",
      "js": "min/*.js",
      "js/lang": "lang/*.js"

After this you can run:

npm update

MySQL privileges update for creating procedures, functions, etc.

After creating a new user you need to update his privileges to grant creation of procedures, functions and so on. Here is a SQL for this.

Select_priv="Y", Insert_priv="Y", Update_priv="Y", Delete_priv="Y", Create_priv="Y", Drop_priv="Y", Reload_priv="Y", Process_priv="Y", File_priv="Y", References_priv="Y", Index_priv="Y", Alter_priv="Y", Super_priv="Y", Create_tmp_table_priv="Y", Lock_tables_priv="Y", Execute_priv="Y", Create_view_priv="Y", Show_view_priv="Y", Create_routine_priv="Y", Alter_routine_priv="Y", Event_priv="Y", Trigger_priv="Y"
WHERE user = "xxxxx";

jQuery executes error function even on success (200) status

Just lost a couple of hours with this problems.

jQuery was executing an error function regardless the jqXHR status. A little bit about setup:
node.js + Express + Backbone + backbone.paginator + Underscore

After upgrading to Express 3.0 an application that was working without any problems stoped to work. Problem - jQuery was always executing an error function for all ajax requests. After checking the code, googling, reading, debugging, taking a lunch, debugging again and again I saw that I was using res.json() and not res.jsonp() (added in Express 3.x). Change of one line and everything is working back again.

So - if your node.js + express 3.x returns jsonp, please, use res.jsonp() instead of res.json()

MySQL PASSWORD() function in JavaScript

If you need to implement a MySQL PASSWORD() function in JavaScript - use with 2 encodings.

Here is an example:

var password = "TestPassword";
var result = ("*"+CryptoJS.SHA1(CryptoJS.SHA1(password))).toUpperCase();
console.log("result : " + result);

Result will be *0F437A73F4E4014091B7360F60CF81271FB73180. If you check it with MySQL password() it will be the same:

mysql> select password("TestPassword") as result;
| result                                    |
| *0F437A73F4E4014091B7360F60CF81271FB73180 |

defaults write AppleShowAllFiles YES

Then relaunch Finder application (Option + right button click on dock icon, then select relaunch).
To disable showing of hidden files - do the same procedure with other string:

Find directory with biggest number of files / directories

Today we had a problem related with a number of files in a directory. We needed to find directories with a biggest number of files / directories in it. Here is a small shell script that will list directories and a number of files/directories in each directory.

find . -type d|awk {'print "echo -n "$1".\"\t\"; ls "$1"|wc -l"'} > /tmp/do; . /tmp/do|sort -k 2 -n -r |more

Explaining it a little bit:

"find . -type d" - find all directories bellow current directory
"awk {'print "echo -n "$1".\"\t\"; ls "$1"|wc -l"'} > /tmp/do" - generate a script that will print a directory name (echo -n), make ls in this directory and count a number of lines from ls (wc -l)
". /tmp/do" - execute generated script
"sort -k 2 -n -r" - sort the result using second column (-k 2) as numerical (-n) and in reverse order (-r)

iPhone takes too long to sync

After changing a notebook I got a following problem. My iPhone was taking an eternity to sync with iTunes. I made a restore - no solution. I made a restore as new iPhone - same problem. After googling a little bit I found that this can be related with "Sync Photos" option. At the moment that I disabled "sync photos" - my iPhone was synced in a couple of minutes.

Problem: iPhone is taking too much time to sync on Windows 7.
Possible solution: Try to disable "Sync Photos" option.

VMware crashes after updating (upgrading) of host OS (to CentOS 5.4)

If you have in your hostd.log something like this:

Nov 07 21:19:12.648: Worker#23| Caught signal 6 -- tid 31543

this can be related with update(upgrade) of host OS.

After upgrading of a host OS (CentOS 5.3->CentOS 5.4) I got an issue - a guest OS started to crash. Searching around for a possible cause I found bug post in CentOS bug tracker. Seems that issue is related to glibc update (last version is glibc-2.5-42) and a fix is to downgrade to previous version on host OS (glibc-2.5-34).

To be sure that your downgrade of glibc worked - check the size of I got an issue on downgrade (even with --oldpackage rpm was not willing to replace a libc), and that's why I lost some hours trying to figure out what is going on. So, be sure to check the size of the files after downgrade. It can save you some hours :)
