i have 2 node processes speak each other. call them [node server] , [node sender] . [node sender] continually processes information , writes message on tcp connection [node server] . [node server] writes status message. example of [node sender]: var message = "test message"; [node sender].connection.write(message); example of [node server]: [node server].socket.on("data", function(p_data) { this.write("ok"); // work p_data } this works without issue, p_data contains "test message" when sent @ above 5 milliseconds. however, if speed [node sender] write every millisecond, p_data ends "test messagetest messagetes" . i understand buffer in [node sender] filling faster write command sending it. there way force one-to-one ratio in sending messages while still remaining asynchronous? i can add terminator message , fill buffer in [node server] , wanted make sure there wasn't obvious missing. ...

innosetup setup executables have command line options permit unattended or batch file operation - i.e. possible have command-line parameters /silent, /verysilent, such no "wizard" pages displayed. if add own wizard pages using createinputoptionpage these still display, i.e. need add further command-line options suppress these (and provide default responses) well? (yes, could try myself, answer useful others, , there might further issues haven't thought of) when run /silent or /verysilent dialogs create such createinputoptionpage not shown. initializewizard() still called , forms still created. so values read these wizard pages default values. you can have specific behavior in pascal script when silent using wizardsilent() function. you can check parameters sent install in pascal script using paramcount , paramstr functions or can whole string using getcmdtail .

i'm develloping android application has local database synchronizes whith online rss. the issue i'm encountering follwoing: want store "lastbuilddate" of rss feed (i have date in string ready store) don't know best way store date after application got closed. i'm thinking of creating new database whith lastbuilddate in sounds bit weird me, figured there might better more suitable solution store 1 string can access later. so there way store in application (like preferences?) or should eventualy create database or file store date in? regards you should create sharedpreference value case. im sure smart enough implement :) sharedpreferences sp= this.getsharedpreferences("sharedp", mode_private); sharedpreferences.editor editor = sp.edit(); editor.putstring("lastbuild", date); editor.commit();

i ran across bit of code , me seems not needed there reason following def answers = [] list instead of def answers = [] in groovy thought [] empty list there no need have list no, there no difference, both create arraylist , list ( java.util.list ) interface anyway.

ok, have property on class: @interface myobject : nsobject { myotherobject *someotherobject; } @property (nonatomic, copy) myotherobject *someotherobject; @end i'm trying create deserialize api response correct objects without explicitly defining class each api attribute maps to. so, there way me find out class property is, if it's nil ? i'm looking method [myobject classforproperty:@"someotherobject"] return class object. note--i'm not looking iskindofclass: or class , won't work on nil value. worst case, can manually define list of property classes, it'd nice if there built in way it. ok, ended figuring out after coming across question: in objective-c determine if property int, float, double, nsstring, nsdate, nsnumber, etc here's code: @interface nsobject (properties) + (class)classforproperty:(nsstring *)propertyname; @end #import <objc/runtime.h> @implementation nsobject (properties) + (class)classfo...

i wrote in function: if(mythread.isalive()) { } else { mythread.start(); } but unsafe if many threads call function same time. start running thread throws exception. so except putting try-catch around it, have other options? make method synchronized. also, check ( isalive() ) unsafe because if thread have been finished cannot start again (and isalive() return false...)

i have form on jquery mobile site validate, , stop submission if validation not pass. however, 'return false' not stop form being submitted, because jquery mobile submitting form via ajax. how can stop form submission? $("#form").live('submit', function(){ alert('test'); return false; }); the above code fires alert, not stop form being submitted. if use data-ajax="false" on form tag works correctly, rather use ajax submission if possible. use data-ajax="false" , bind own ajax form submission code runs if validation passes: $("#form").live('submit', function() { if (formvalidates) { $.post(...); } return false; });

i have array sorting function follows: public function sortascending($accounts) { function ascending($accounta, $accountb) { if ($accounta['amountuntilnexttarget'] == $accountb['amountuntilnexttarget']) { return 0; } return ($accounta['amountuntilnexttarget'] < $accountb['amountuntilnexttarget']) ? -1 : 1; } usort($accounts, $ascending); return $accounts; } clearly not ideal hard-coding key search for. thought make generic passing key param outside function, out-of-scope in inner function. tried around using closure, have access param, instead of inner function follows: public function sortascending($accounts, $key) { $ascending = function($accounta, $accountb) { if ($accountsa[$key] == $accountb[$key]) { return 0; } return ($accounta[$key] < $accountb[$key]) ? -1 : 1; } usort($accounts, $ascending); return $accounts; } however us...
