i working on project requires heavy modifications in linux kernel. in 1 of modifications have change way page fault handler works. to intercept page faults specific processes , satisfy them possible getting copying data machine. as first step, write experimentation code can me understand how linux satisfies page fault , how tells process page fault can not served right , needs retry @ later time. so, modify handle_mm_fault in way helps me understand above. this: int handle_mm_fault(struct mm_struct *mm, struct vm_area_struct *vma, unsigned long address, unsigned int flags) { /* code */ if(current->pid == my_target_pid) { /* 1. chose randomly between 1 , 2 -> rand_num 2. if rand_num (1) 1 allocate block of memory, write 'x's , give process , return. 3. if rand_num (1) 2 tell process come later , return. */ } /* rest of handle_mm_fault other process here */ } yo

i trying implement stackedcolumn type chart in project, find understand how assign different series . this demo purpose code: for (int = 1; <= 3; i++) { (int = 0; < 5; a++) { string item = "boo" + i.tostring() + a.tostring(); chart1.series.add(item); chart1.series[item].charttype = seriescharttype.stackedcolumn; chart1.series[item].points.addxy(i, 100.0); } } however, produces flying 3 stacked columns instead of 3 equal stacked columns: however, if remove seriescharttype.stackedcolumn (and use default) works fine , go ground. how should make them go bottom using stackedcolumn ? you creating chart 15 series, each series has 1 data point. trying achieve? example if wanted have 3 series, each 5 data points should this: for (int = 1; <= 3; i++) { // add series chart string item = "boo" + i.tostring(); chart1.series.add(item); chart1.series[item].charttype = seriescharttype.s

i'm developing file reader complex format. there literally hundreds of different entries. in way i'm doing need use 2 streamreaders because need extract information before. these files big enough not read them @ once. what want notify user lines have not been read. structure this: streamreader file1 = new streamreader(path); while((line=file1.readline()) != null) { if(line.startswith("hello") { //... } //... more conditions } streamreader file2 = new streamreader(path); while((line=file2.readline()) != null) { if(line.startswith("good morning") { //... } //...more conditions } so if reader perfect @ end lines read. things can bizarre entries can not yet implemented, , want catch lines. problem here, see, having two streamreaders . my options are: store in array not read lines , use second reading, subtracting line line after reading it. not because storing several thousand of lines there. add conditions in second streamreader

i have epoch times stored in database so: 1392821307. these picked on separate web service using php time() function. need convert date/month/year format in titanium. so far have used following code based off answer here in stack overflow var utcseconds = jobs_data.jobs[i].dateposted; var d = new date(0); // 0 there key, sets date epoch d.setutcseconds(utcseconds); this returns string so: wed feb 19 14:48:27 gmt 2014 i need feb 19 2014. i'm wondering how parse string. going use substring example, mon have 3 letters , thurs have 4, starting index of parse changing. not sure if month of varying length also d date object. if pass ti.api.info, or console.log, it'll coerced in string see above. should use getdate , getmonth , , getfullyear methods string want. var formattedstring = (d.getmonth()+1) + '/' + d.getdate() + '/' + d.getfullyear(); alternatively, use moment.js , included in alloy apps, , can downloaded in vanilla titanium apps

hi guys, have achieve above design. here no of bubbles dynamic (maximum 8) , size of each bubble dynamic. have designed bubbles dynamically can't find out way add bubbles (i mean in position, bubble) output looks above. bubble formed randomly each , every times 2 bubbles for 4 bubbles but there no particular logic time 2 , 4 bubbles position same. to honest far away start cause couldn't figure out logic. idea, appreciable. thank you. do: create class method set frames prepare layout how display. depend on no of bubbles. for ex: if 1 bubble show in center screen if 2 bubbles show both in 1 line if 3 bubbles make round display if 4 bubble square display if 5 bubbles shape shown image here above so define frames buttons checking no of bubbles. after you'll need use class code. automatically take frames defined in class.

i have titleareadialog tableviewer allows user select row table. problem is, content of table may change on time. implement refresh behaviour commonly found in browsers (e.g. pressing f5 content of table should refresh). below screenshot should make scenario little clearer: it looks there possible solution in this question , think flawed several reasons: the listener isn't detached (e.g if reopen dialog have 2 filters on display ) it doen't add listener titleareadialog or widget believe belongs architectural point of view. i avoid manual listener-attaching/detaching (e.g. listener should disposed titleareadialog ) long story short: proper way of adding keylistener titleareadialog (or dialog in general) without using filter mechanism described in aforementioned question ? i know question somehwhat fails in sscce department, pointers right direction highly appreciated. adding listener key events tricky thing. want listener fired when non

i'm using spring tcp-inbound-gateway listen socket connections on server side. i wonder if socket connection automatically closed after response end client? not find in spring docu: http://docs.spring.io/spring-integration/reference/htmlsingle/#ip-endpoint-reference <ip:tcp-inbound-gateway id="gateway" connection-factory="factory" request-channel="channel" /> further question: how can specify timeout socket connection should kept alive? , close socket if response not send client within time interval? set single-use="true" on connectionfactory , close socket after sending reply. use so-timeout set timeout socket option , socket closed after inactivity. see reply-timeout on inbound gateway. see configuration section of reference manual attributes , meaning.

overriding case: class a{ public void m() {} } class b extends { @override public void m(){} } hiding case : class { public static void m(){} } class b extends a{ public static void m(){} } is 1 instance method hiding another? interface { void m(); } interface j { void m(); } class implements i,j { void m(){} } can instance method hide instance method? class { public static void m(){} } class b { public static void m(){} } these classes don't share common ancestor, 1 can't "hide" other's method. in java, same-name instance methods in subclasses override superclass's instance method, there no hiding mechanism there in other languages (such pascal if remember correctly). true if @override annotation isn't made, annotation makes code more readable , helps against typos. if changed class b extend class a , however, it's static method m() in fact hide same name method in a . this the oracle docs h

i want show long list of reviews may contain links. how can show them user can click , open links? this question has been asked lot, couldn't find functional answer, obsolete answer seems isn't working: <textblock> <run>let me</run> <hyperlink navigateuri="http://www.google.com">google</hyperlink> <run>that you</run> </textblock> also richtextbox doesn't support data binding it? reviews shown inside longlistselector this: <phone:longlistselector itemssource="{binding reviews}"> <phone:longlistselector.itemtemplate> <datatemplate> <textblock text={binding review}/> </datatemplate> </phone:longlistselector.itemtemplate> </phone:longlistselector> you missing text property, here complete example of how add links inside richtextbox hyperlink inside rich textbox

i trying wait take user's input (clicking button) before continuing program. simplified version of code this: $(document).ready(function(){ var answer = $(".question").on("click", "button", takeanswer); alert(answer); }); //code set next question once user has answered previous question function takeanswer(){ var answer = ($(".question button").data("answer")); alert(answer); return answer; } the html body contains this: <p class="question"><button data-answer="1">push me</button></p> on loading, html alerts [object object] . once click button, page alerts 1 supposed to. think problem return line executing without awaiting user's click. research suggests need use callback function (there several discussions on waiting user input), i'm confused because thought putting takeanswer code in separate function keep subsequent code executing. for furt
