memory management - How to serve a page fault in the linux kernel? -

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

indexing - Clarification on sorting subsets in mongodb -

i have documents fields a, b, c, d, e, p in mongodb. have indexes { a: 1 } , { b: 1 }, { c: 1 }, { d: 1 }, { e: 1 }, { p: 1 } , compound indexes { a: 1, b: 1, c: 1 } . field p represents position of fields. if have select this: { a: 'something', b: 'something else', c: 'and again' } , know use index { a: 1, b: 1, c: 1 } search (obviously). however, if want sort p ( { p: 1 } ), indexes used sort data? worried because can potentially have large dataset. i read http://docs.mongodb.org/manual/tutorial/sort-results-with-indexes/ , cannot quite figure out use case (although it's there) probably best said "can mongodb use 1 index match , 1 sort?" , answer no. the thing "looking" in explain output see if index used sort value scanandorder show true when index cannot used , false can. considering adapted sample, compound index on "a", "b", , "c" , separate index on "p", que

delphi - How to define that node of TVirtualStringTree is presented on screen? -

it's easy check node visible. don't know how rightly define node presented on screen. can find out so: bottomnode := tree.bottomnode; node := tree.topnode; idbottomnode := tree.absoluteindex(bottomnode); while tree.absoluteindex(node) <> idbottomnode begin node := node.nextsibling; if not assigned(node) break; end; (code without checking) but think rather rough way. may there more accurate way? you may write function follows. tree parameter there specifies virtual tree, node node want check if it's visible, , column optional parameter index of column if need determine whether node , column visible in client rect: function isnodevisibleinclientrect(tree: tbasevirtualtree; node: pvirtualnode; column: tcolumnindex = nocolumn): boolean; begin result := tree.isvisible[node] , tree.getdisplayrect(node, column, false).intersectswith(tree.clientrect); end; but maybe there's more straightforward way...

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

ios - Add Bubble view dynamically -

Image
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.

java - Adding KeyListener to TitleAreaDialog -

Image
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

in Java can one instance method hide another method? -

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
