i use ebs volume data on i've been working in ubuntu ami in redhat 6 ami. issue i'm having redhat says volume not have valid partition table. fdisk output unmounted volume. disk /dev/xvdk: 901.9 gb, 901875499008 bytes 255 heads, 63 sectors/track, 109646 cylinders units = cylinders of 16065 * 512 = 8225280 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0x00000000 disk /dev/xvdk doesn't contain valid partition table interestingly, volume isn't 901.9 gb 300 gb.. don't know if means anything. concerned possibly erasing data in volume accident. can give me pointers formatting volume redhat without deleting contents? i checked volume works in ubuntu instance , does. i'm not able advise on partition issue such, other stating neither need nor want format it, because formatting indeed (potentially) destructive operation. best guess redhat isn't able identify file

i'd know if possible following: using (myclass o = new myclass()) { theclassiwantmyclasstosee x = new theclassiwantmyclasstosee(); x.dostuff(); } i'd create class (myclass) , use in using block. inside block, want work objects of type (theclassiwantmyclasstosee). when using block falls out of scope, want perform actions on these (theclassiwantmyclasstosee) objects. is possible make class aware of other objects declared in scope transparently? i realise add object instances myclass object, i'd make easier developers working api i'm building. any ideas welcome. thanks. the way make myclass aware of theclassiwantmyclasstosee creating reference 1 other. there no way navigate , explore classes in scope. statement true regardless of whether scope relates using block, method block, foreach loop or other. why not have simple myclass.addrelationship(theclassiwantmyclasstosee child) method makes class a

possible duplicate: what's difference between path_not_found , name_not_found i error_file_not_found when try open file that's not there, fopen fails error_path_not_found . so difference between error_file_not_found , error_path_not_found ? in winerror.h , error_file_not_found has descriptive text "the system cannot find file specified." , error_path_not_found has descriptive text "the system cannot find path specified." this doesn't particularly clarify matters. usually, however, "file not found" refers case file cannot found , "path not found" refers case component of path (one of directory names specified) cannot found.

let suppose have 2 threads , single global variable in python code threading module. in code, thread-1 modifies global variable's value, whereas, thread-2 reads value of global variable , perform task depending on value. in situation, need protect access global variable lock()? in c, mutex must used under such condition. however, python gil? still case? lock() still required? assigning object value global variable atomic operation in python. other threads cannot read variable incorrectly reading while it's being assigned. gil guarantees in c implementation of python, other implementations can , make same guarantee in different ways. if global variable mutable object, list, , modifying object, depends on method use. methods on builtin objects lists atomic. i can't sure don't need lock, though, without knowing more details purpose of variable , how using it. why thread-2 need change behavior based on value, , ok if thread-1 changes value after thread-2

as know can override few methods each type of view have created. not doing xml layout code because lot of stuff changes form @ runtime , there things created dynamically programmatic solution best route me here. so gist of issue lets have 50 buttons in android app. these buttons potentially on 1 activity more span out across multiple screens(activites). i have created button class called custombutton overrides onclick(view view) method. if of buttons supposed action(lets part of linearlayout) , part of relative layout , in each relative layout want information relative layout button resides in(perhaps information textviews in same relative layout, etc etc). one solution of course id of each button , switch(case) or , depending on id of button returned can something. problem is have 50 buttons. if had 200? should have 200 case checks in switch statement figure out action need take? so trying figure out information available me not aware of use when override onclick. @ov

i know perl , python tested solution kind of log parsing , data mining - anybody have experience dealing syslog parsing java ? i have create java demon anyway load parsed output db .. thinking why not going way - python might useful when running on different environment. i started writing python scripts, wrote java gc log parser print timestamp when gc happened , counts etc, , found python real easy in writing it. kind of fields interested while parsing syslogs? think if know looking in logs(patterns etc) becomes easy write script you. ankit.

i have <div> containing <video> element, , <ul> . clicking on element in <ul> causes ajax call update contents of <div> . on first attempt, first video load correctly, clicking on different link load poster, not controls. after googling, found solution that, leaves me following ajax call: $.ajax({ // each video has own unique id url: "/video?id=' + id, success: function (data) { $('#containing_div').html(data); // necessary re-load video player controls _v_('video_' + id, { "controls": true, "autoplay": false, "preload": "auto" }); } }); adding initialization call _v_ seemed matters somewhat: when switch videos, "play" control appears expected, , can play video. however, once do, when switch different video, controls gone again. furthermore, there weird random errors: if change videos few times, controls disappear no apparent

i have io.readcloser object (from http.response object). what's efficient way convert entire stream string object? the short answer it not efficient because converting string requires doing complete copy of byte array. here proper (non-efficient) way want: buf := new(bytes.buffer) buf.readfrom(yourreader) s := buf.string() // complete copy of bytes in buffer. this copy done protection mechanism. strings immutable. if convert []byte string, change contents of string. however, go allows disable type safety mechanisms using unsafe package. use unsafe package @ own risk. name alone enough warning. here how using unsafe: buf := new(bytes.buffer) buf.readfrom(yourreader) b := buf.bytes() s := *(*string)(unsafe.pointer(&b)) there go, have efficiently converted byte array string. really, trick type system calling string. there couple caveats method: there no guarantees work in go compilers. while works plan-9 gc compiler, relies on "implementation deta

i have been on one, , plumb stuck. have been building project , want embed text file resource executable. understand basics of how "should" work, reason not. so, let me start have far , maybe problem can pinned down. there 2 functions here, first, enumresnameproc attempt debug problem self, second, loadfileinresource function trying working. little messy because in middle of building when starting having problems. the exact issue is, findresourceexa returning null, , lost exact reason. know error, , return code 1813, "resource not found". i have other resources in project, have version node, mainifest node, (of which, not directly reading) have icon node (that applying window system menu icon) , bitmap (that loading texture.). these have defined types, example, type bitmap 12. now, attempting load text file, 'user defined' type of 10. know data inside executable, because if open in text editor...
