"Read-only input in Android Webkit not working",
"I have a text input field in my web page that I am using to collect a date (via the jQuery Tools .dateinput). The user does not need to be able to type into the field. A dialog box appears when the field is clicked on. This is a problem on my Motorola Droid, because I don't want the soft-keyboard to appear when the field is clicked.\n\nI have tried input.blur() on focus and also setting the field to disabled and readonly. Setting the field to disabled has undesired side effects. Setting the field to readonly works in everything but the Android browser. The browser seems to recognized the \"readonly\" attribute (or readOnly via javascript), BUT the field does not actually become readonly. When you click it, the soft keyboard still appears and allows you to change the field.\n\nI suppose that this is a bug in the Android browser. Can anyone come up with a clever alternative?"

"I've the following problem, that showed up when I installed my webapp's war on a virtual linux server. Here it is: my server system time seems correct, in fact typing date on shell comes out with:\n\nMon Apr 11 11:47:30 CEST 2011\n\n\nwhich is my \"wall clock time\". Even mysql works fine, if I do select now(), I get:\n\nmysql> select now()\n -> ;\n+---------------------+\n| now() |\n+---------------------+\n| 2011-04-11 11:52:57 |\n+---------------------+\n1 row in set (0.01 sec)\n\n\nBut my application (Spring+hibernate on Java6 + tomcat 6) will save every date on DB with a GMT timezone (and the time is correctly offset with the difference from GMT, which is good). Now the problem is that I get all dates displayed with GMT, even if I do:\n\nstatic final DateFormat format = new SimpleDateFormat(\n \"dd/MM/yyyy 'alle' HH:mm\", Locale.ITALY);\n\n\nI don't get the hours correctly offset, but they remain in GMT and they display GMT if I put Z (that displays timezone) in the pattern. \n\nUnder Windows instead I had date values stored in my native timezone on mySQL. So on my windows machine where I develop I will have all the dates in CEST. This is annoying as I don't know how to predict the way the system will behave and I have to do boring tests and figure out how to change this.\n\nDo you have ever seen this problem?

"Authenticating Rails App w/ Soundcloud, Getting 401 Unauthorized Error: invalid_grant",

That doesn't make sense to me because I'm not reusing the access_token later, I'm just doing the initial authentication. Just in case I included the scope => non-expiring parameter when I redirected to Soundcloud, which made no difference.\n\nAny suggestions? Has anyone had success integrating Rails with Soundcloud recently? All of the resources I've found seem quite outdated."

"I'm trying to make a Watch Dog function using an inner class broadcast receiver. On the parent class I registered the broadcast receiver inside the constructor, but the onReceive class is never trigger.\n\nHow can I solve this issue ? Thank you.\n\nWatchDog class:\n\npublic class WatchDog {\nprivate final String TAG = getClass().getSimpleName();\nprivate static final String RECEIVER_WATCHDOG = \"com.example.liviu.test_broadcastreceiver.receiver\";\nprivate final static String ACTION_WATCHDOG = \"com.example.liviu.test_broadcastreceiver.action.watchdog\";\nprivate final static int ID_WATCHDOG = 40856342;\nprivate final static int mTimeout = 1000;\n\npublic WatchDog (Context context) {\n Log.d(TAG, \":::::::::::: Watchdog CONSTRUCTOR\");\n IntentFilter intentFilter = new IntentFilter(RECEIVER_WATCHDOG);\n BroadcastReceiver receiver = new WatchDogReceiver();\n context.registerReceiver(receiver, intentFilter);\n setWatchdogTimer(context, true, mTimeout);\n}\n\nfinal class WatchDogReceiver extends BroadcastReceiver {\n\n @Override\n public void onReceive(Context context, Intent intent) {\n Log.d(TAG, \":::::::::::: Watchdog received - \");\n setWatchdogTimer(context, true, mTimeout);\n }\n}\n\npublic void setWatchdogTimer(Context context, boolean set, int timeout) {\n Log.d(TAG, \":::::::::::: Watchdog START\");\n Intent intent = new Intent(context, WatchDogReceiver.class);\n intent.setAction(ACTION_WATCHDOG);\n PendingIntent alarmIntent = PendingIntent.getBroadcast(context, ID_WATCHDOG, intent, PendingIntent.FLAG_UPDATE_CURRENT);\n AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);\n if (set) {\n alarmManager.set(AlarmManager.RTC, System.currentTimeMillis() + timeout, alarmIntent);\n } else {\n alarmManager.cancel(alarmIntent);\n }\n}\n\n\n}\n\nand MainActivity class:\n\npublic class MainActivity extends AppCompatActivity {\nprivate final String TAG = getClass().getSimpleName();\n\n@Override\nprotected void onCreate(Bundle savedInstanceState) {\n super.onCreate(savedInstanceState);\n setContentView(R.layout.activity_main);\n\n Log.d(TAG, \">>>>>>>>>>>> Activity START\");\n new WatchDog(getApplicationContext());\n}\n\n\n}\n\nLogcat is showing only:\n\n05-02 18:11:10.197 20415-20415/com.example.liviu.test_broadcastreceiver D/MainActivity: >>>>>>>>>>>> Activity START\n05-02 18:11:10.197 20415-20415/com.example.liviu.test_broadcastreceiver D/WatchDog: :::::::::::: Watchdog CONSTRUCTOR"

"Datetime difference in hours minutes and seconds moment.js in node js",
"I am new to nodeJs and using moment.js in my projects. I would like to calculate datetime difference resulting into hours minutes and seconds. I googled but did not got related solution.\n\nHere is the code and my effort on google. \n\nvar moment = require('moment');\n\nvar now = \"26/02/2014 10:31:30\";\nvar then = \"25/02/2014 10:20:30\";\n\nvar config = \"DD/MM/YYYY HH:mm:ss\";\n\nvar duration = moment.utc(moment(now, config).diff(moment(then,config))).format(\"HH:mm:ss\");\n\nconsole.log(duration);\n\n\nThis prints 00:11:00\nexpected result is 23:11:00\n\nany help would be appreciated and thanks in advance."
