can post public message application, , if so, automatically send message public feeds of users of application have authorized offline_access,publish_stream ? note : when user clicks application's "subscribe" button explicitly doing informational updates published feeds, request offline_access,publish_stream , have authorize that. this question sending 1 message @ once instead of iterating on each user of application. i think can done pages. technical part: yes, possible send application feed message through facebook api. to perform need give "publish_stream" permission account you're sending message from. after can schedule messages sent without authentication. sociel part: users see messages in feeds until explicitly hide application streaming.

the windows console has been unicode aware @ least decade , perhaps far windows nt. reason major cross-platform scripting languages including perl , python ever output various 8-bit encodings, requiring trouble work around. perl gives "wide character in print" warning, python gives charmap error , quits. why on earth after these years not call win32 -w apis output utf-16 unicode instead of forcing through ansi/codepage bottleneck? is cross-platform performance low priority? languages use utf-8 internally , find bother output utf-16? or -w apis inherently broken such degree can't used as-is? update it seems blame may need shared parties. imagined scripting languages call wprintf on windows , let os/runtime worry things such redirection. turns out even wprintf on windows converts wide characters ansi , before printing console ! please let me know if has been fixed since bug report link seems broken visual c test code still fails wprintf , succeeds writeconsolew

can spring framework override annotation-based configuration xml-based configuration? need change dependency of bean defined via annotations , not author of bean. this should ok. spring bean context allows redefine beans, "later" definitions overriding "earlier ones". should apply xml-defined beans annotation-defined beans, if they're mixed. for example, if have @configuration public class myannotatedconfig { @bean public object beana() { ... } } <bean class="com.xyz.myannotatedconfig"/> <bean id="beana" class="com.xyz.beana"/> in case, xml definition of beana should take precedence.

situation follows: have java application, communicates on tcp microcontroller tcp stack on it. stack on controller works fine, can sort out. problem is: when terminate connection controller, use socket.close() , connection terminated, no problem. on mac, works too, when check wireshark, there regular termination process [fin,ack] - [ack] , followed [tcp dup ack] packet, that, claimed wireshark, belongs [fin,ack] packet. happens on mac , not happen on windows machine on vm on mac or on netbook... are there tweaks use not letting dup-ack packet transmitted? jerks stack in controller claiming closed session still active , after 10 times connecting controller, stack has no more space accept new connections. i'd thankful if give me hint! well, if problem in os-provided tcp stack (which believe is) may try telnet mac device , close connection. see whether dup ack still emitted. if is, swapping java versions/vendors (for example) won't good... ...oh, , maybe y

is possible fetch histogram of image mini_magick or image_science? i afraid mini_magicks usage of mogrify not allow such information retrieval. image_science hardly documented , seems limited thumbnail scaling , cropping only. one route take, iterate on each pixel , extract values, in ruby. requires information on pixels, cannot in mini_magick either. i can fallback either rmagick or im_magick, either less popular/unknown or reportedly bad in performance. for record: part of earlier question finding entropy of parts of images . a workaround use mini_magick convert file png format, store result in temporary file, , use "almost-pure ruby" png library or actually-pure ruby chunky_png go on result. both libraries make easy iterate on image pixel pixel. i'm suspecting specified mini_magick/image_science because these lot easier install than, say, rmagick. reason workaround might work you, then, png , chunky_png pain-free installs due lack of depende

suppose current task stacks has 4 activity instances, a0, a1, b0, c0, c0 @ top of stack. a0, a1 instances of activity a, b0 instance of activity b, , c0 instance of activity c0. now c0 creates intent flag_activity_reorder_to_front , starts activity a: intent intent = new intent(this, a.class); intent.setflag(intent.flag_activity_reorder_to_front); startactivity(intent); my question is, instance brought front, a0 or a1? task stacks become a0, b0, c0, a1 or a1, b0, c0, a0? thanks. empirical evidence says brings most recent instance front. in example, if activity stack starts out this: a0, a1, b0, c0 (front of task) and c0 starts intent.flag_activity_reorder_to_front , instance a1 brought front , activity stack looks this: a0, b0, c0, a1 when use flag, android looks instance of activity (starting front of task , scanning back/root of task). first instance finds brought front. if doesn't find instance in activity stack create new one.

i'm trying improve interesting algorithm as can. for now, have this: using system; class program { static void main() { ulong num, largest_pfact; uint = 2; string strnum; console.write("enter number: "); strnum = console.readline(); num = ulong.parse(strnum); largest_pfact = num; while (i < math.sqrt((double) largest_pfact)) { if (i % 2 != 0 | == 2) { if (largest_pfact % == 0) largest_pfact /= i; } i++; } console.writeline("largest prime factor of {0} is: {1}", num, largest_pfact); console.readline(); } } so ideas? thanks! edit : implemented ben's algorithm, eveyone help! i've got faster algorithm here . it eliminates square root , handles repeated factors correctly. optimizing further: static private ulong maxfactor (ulong n) { unc

i saw comment on question (i forget one) encouraging asker avoid testing his/her code in debug harness unless strictly necessary, citing effect of acting crutch. there's said developing skill deduce cause of bugs without "direct" evidence. i'm quite fan of debuggers myself (in fact, tend run without if strictly necessary), got thinking relative merits of each approach. debugger pros starting obvious, takes less time 0 in on faults, exceptions , crashes tracing provides nice alternative littering code commented-out print statements performance overhead can give wiggle room, i.e. if program responsive while debugging, in wild debugger cons performance overhead can make iterations slower (edit) tunnel vision : debugging symptom can distract deducing cause when crash occurs long after or far defect it may "help" initializing variables or otherwise masking bugs, leading surprises later on conversely, there's odd bug only crops in debug c

i'm migrating php app rails. new app has different schema. anybody have experience data 1 schema another? right now, i'm looking @ dumping csv files , writing ruby scripts handle insertion on other side. i've considered using navicat export/import temp database new schema (if it's simple enough), dump database , insert values new database using db:seed. i figure gonna total pain whichever way go -- hoping minimize angst. in advance! update: decided export navicat xml, use nokogiri create seed files seed_fu. check out dr. nic's magic model gem. http://magicmodels.rubyforge.org/dr_nic_magic_models/ then use rake tasks iterate through csvs , insert using newly generated models.

i trying host 2nd website (outside of default web site, used) web service supported .net 4. iis 6. the default web page using .net 2.0. in iis 6 can have 2 seperate websites running different versions of .net creating 2 distinct application pools. i've done this. however running common problem asp.net tab not appear in iis. tab allows set version of .net site uses. my workaround change .net version each site references through command line: aspnet_regiis -s (site path) the other solution problem switch iis 64-bit mode, causes asp.net tab appear. problem switching iis 64-bit not jive existing website, after reconfiguring iis reference following directory, microsoft.net/framework64 as opposed to microsoft.net/framework is experienced hosting seperate pages on 1 server this? nightmare. can 2nd page work, original default page fails, , vice versa. i have iis in 32-bit mode , ran following cmd line: c:\windows\microsoft.net\framework\v4.0.30319>aspnet_regiis

i new apache commons-exec. is there way can send series of commands remote machine without authenticating each time? would order: ssh a@b command1 command2 but apparently commons-exec needs this: ssh a@b \n command1 ssh a@b \n command2 any idea? try ssh a@b "command1; command2" this common way execute multiple command on remote system via ssh within script. should work case well.

can help? i have class file called member stores object reference , object reference of parent. have list contains "many" members. flat file system, works great linq can see give me childs has parent of x. using object reference field of parent property. now thinking of recreating class file , adding new field hold list of member , remove parent property - way have 1 object there other objects object. hope makes sense? :-) so if have new object, how use linq childs of specific parent? direct descendent? , possible flatten file i.e return items single objects part of list. i love hear anyones comments on method better, i.e. have , hierarchy approach. thanks in advance anytime hierarchical collections, remember there multiple different data structures handle type of problem. there 1 that's rather complex, provides amazing performance. consists of dictionary keyed off integers containing entire collection. objects keep parent relationship, , have hashs

i read mutex , binary semaphore different in 1 aspect, in case of mutex locking thread has unlock, in semaphore locking , unlocking thread can different? which 1 more efficient? assuming know basic differences between sempahore , mutex : for fast, simple synchronization, use crticial section. to synchronize threads across process boundaries, use mutexes. to synchronize access limited resources, use semaphore. apart fact mutexes have owner, 2 objects may optimized different usage. mutexes designed held short time; violating can cause poor performance , unfair scheduling. example, running thread may permitted acquire mutex, though thread blocked on it. semaphores may provide more fairness, or fairness can forced using several condition variables.

we have custom canvas has specialized nodes behave lot standard mdi application's windows. desired behavior if of child controls of "window" have focus, "window" said active. now isfocused property doesn't seem cascade, meaning if child control has focus, it's container not set 'focused' can't use that. same reason, can't set isfocused property on container believe steal child. my thought create new dp called haschildwithfocus or that, in code-behind, listen bubbled events , set flag. not sure that's best way go. (we may implement combination attached property/attached behavior kinda thing.) but of course better if ask control 'hey... or of children have focus?' so can you? you can use uielement.iskeyboardfocuswithin directly this: <grid> <grid.resources> <style x:key="panelstyle" targettype="border"> <setter property="borderbrush

according python docs here , when leaving type out, defaults type of 'g' floating point arguments. however, print("{0:.2}".format(14.9)) prints "1.5e+01", while print("{0:.2g}".format(14.9)) prints "15" is issue of documentation being incorrect or there reason it? according source code , documentation bug. correct description behaviour without floating point specifier "like 'g', @ least 1 digit after decimal point".

in application have array 5000 elements. have sort these elements.but getting error of "array index out of bound exception". can tell me can maximum size array sort? should use arraylist ?? there no specific limit - constrained memory here, , @ point array exists, isn't limitation of array.sort . example: int[] arr = new int[500000]; random rand = new random(); (int = 0; < arr.length; i++) arr[i] = rand.next(); array.sort(arr); // works fine i suspect might (for example) have icomparable[<t>] implementation throwing error internally? or alternatively, perhaps error has nothing @ do array.sort , , have considered wrong line cause. the exception's .stacktrace should reveal everything, of course. and no: shouldn't use arraylist here. or pretty anywhere else.
