note i'm not talking specific implementation in specific language. lets have thread pool , task queue. when thread runs pops task task queue , handles - thread might add additional tasks task queue, result. time thread has handle task unlimited - meaning thread works until task finished , never terminates before that. what kind of problems (e.g. deadlocks) each following thread pool configurations susceptible to? possible thread pool configurations i'm concerned with: 1) unbounded task queue bounded num. of threads 2) bounded task queue unbounded num. of threads 3) bounded task queue bounded num. of threads. 4) unbounded task queue unbounded num. of threads also - thread has limited time handle each task, , forcibly terminated if doesn't finish task in time frame given. how change things? if have bounded number of threads can experience deadlocks if task running on pool thread submits new task queue , waits task --- if there no free thread new task...

i've written code test if user has changed values in of 6 edittext boxes, code looks bulky , redundant. i'm wondering if there more elegant way this. the user inputs numbers of 6 edittext boxes, , after each entry, calculation routine checks sure boxes have valid numbers before doing calculation. kistener has fire on lost foucus number in box before calculations done. , outputing result. if user want go , change value in 1 of 6 edittext boxes, calulation routine runs again.been i've set 6 listeners in oncreate section each edittext box. have 6 separate routines test each hasfocus==false. within oncreate section set listener each of 6 user input edottext boxes: et1.setonfocuschangelistener(this); . . . . et6.setonfocuschangelistener(this); then have method check if edittext box has lost focus, suggesting theat user changed data, , therfore re-run calulations. check each of 6 user input edittext boxes follows: @override public void onfocuschange(view v, bo...

i'm on quest learn how layout components in android. i'm seasoned css/mxml developer , having hardest time getting full understanding of layout properties in android components. one thing i'm not sure differences between these: layout_margin vs. padding layout_gravity vs. gravity vs. ignoregravity should use 1 on other linear, table or relative layouts? example of i'd learn having overall margin on layout separate components relating top/middle/bottom of screen. sdk docs start, don't show how things work in different situations. any tips on go learn more complex/comprehensive layout design? any attribute prefix layout_ layoutparams attribute. while view attributes parsed during view construction view itself, layoutparams special arguments parent view provide hints how parent should size , position child view. layoutparams valid on view depends entirely on type of parent view. layout_margin therefore instruction parent view supports ma...

i'm reading book (head first object oriented design & analysis). in chapter 5 there suggestion have other toughts it. book says: "when have set of properties vary across objects, use collection, map store proeprties dynamically." and further more, explaination why it: "you'll remove lots of methods classes, , avoid having change code when new properties added app". i understand advantage of approach isn't there downsize well? mean if use map store informations (in example string enum map) , provide getproperty(string) method access, caller of method has know strings allowed. don't somehow. mean of course can argue stated in javadoc input allowed. is way deal kind of problem there alternatives? understand doing inheritence not because of bulk of subclasses , subclasses not override add new properties isnt in opinon. i think using map instead of actual fields terrible idea. had misfortune work systems emp...

is there symbol, or other convention, indicating endianness of value/variable/what-have-you in technical writing? that is, if wanted describe algorithm or formula, , represent formula mathematical expression (e.g. x = p + 2 / y), there way of indicating endianness of 1 of variables? for example: the following formula shows how calculate new pointer value, npnt . when working old pointer value, stored in int variable pnt , keep in mind stored little-endian, while new , offset big endian. in order perform mathematical operations using value of pnt , must change pnt big-endian. int pnt = 0x1722 int new = 0x900f int offset = 0xf600 npnt = offset + new - pnt this random example. main thing concerned formula - without paragraph explanation above, there no indication of endianness of each variable in formula. the solution came superscript arrow symbol variables so: npnt → = offset → + new → - pnt ← or, better yet, put arrows di...

i have 2 buttons. if 1 button clicked, part 1 of file should displayed. when other button clicked, other part should displayed. and have able switch between pages anytime. anyone idea how (in php)? first of all: should express have tried achieve , why things not working. really basic stuff , after reading php manual , html tutorials, should able thing going on own. the easiest way make buttons include different parameter: <button onclick="window.location.href='index.php?page=foo';">click me</button> <button onclick="window.location.href='index.php?page=bar';">click me</button> and read out parameter php: <?php if (isset($_get['page'])) { switch($_get['page']) { case 'foo': // include page foo break; case 'bar': // include page bar break; } } disclaimer: said easiest , not most elegant . :)

i have map on page displays several places markers , infowindows. i'd put fullscreen button , load map jquery-ui dialog, i've got problems. is there way copy google map instance i've created in 1 div, other div? or other workaround, changing div associated map... science-fiction?? i don't think google maps support such manipulation. although seems moving map quite simple. map has method getdiv returns node containing map. using jquery can manipulate dom: var mapnode = that.map.getdiv(); $('#destinationdiv').append(mapnode); it moves map div destinationdiv. tested in chrome , firefox , worked well, i'm not sure if works (if map's functionality isn't broken) in main browsers. but wasn't successful in copying map. utilizing jquery's clone method produces broken copy of map. if need copy it, guess way might create new map , create objects scratch.

there research articles (e.g. chakrapani & palem ) , devices (e.g. lyric ) use so-called probabilistic logic. suppose idea outputs of such device, given inputs, converge probability distribution. difference between these devices , using analog signals? is, these devices still considered digital, analog, mixed-signal? this paper seems describe novel kind of (probabilistic) boolean logic, , not implementation. skimmed through paper, seems 1 of theories. there is, way, simple reason why probabilistic logics don't give classical logics give you, namely, not truth functional (i.e. value of & b not depend solely on value of , value of b). as implementing such thing on chip: think both possible. if digitally, you're calculating probabilities, , can run code on cpu. don't know analog implementations, guess elementary analog component (transistor, opamp etc) can seen performing kind of basic arithmetic operation on voltages , currents. whether circuit gives ou...

i working on application user authentication happens in coldfusion application (based on cfwheels), interactions file servers happen through node.js application. need make sure user logged in on cf application allowed access files in node server. thinking of setting cookie cftoken or node server can read , pass coldfusion asking "hey can token access file" my problem wasn't sure if cftokens re-used eventually, , if should use instead? if other people have other ways of doing sort of thing authentication needs reusable across multiple engines love hear strategies. that sounds fine way it. but, use cfcookie set cookie of own devising. the 2 servers have share domain name, of course, able read same cookie. have set cookie domain cookie. one clean way architect create whole cfc devoted security. it have methods generating , validating login tokens. your cf application use generate token, , have node.js application call via webservice using the ...

like web developers, used use mysql of db needs. i'm interested in mongodb, , trying integrate project i'm building. problem is, because don't have experience mongodb, i'm having little difficulty deciding on feature. never had live website using mongodb, i'm not sure if it's this. this site available in several languages. decided store text in place, able programatically fetch needed ones in correct language. if using mysql, not use purpose. i'm using mongodb, , seems logical use storing lot of text , later fetching. do think it's idea? it's document store, should ideal this, i'm imagining having lots of queries fetching data db, , doesn't seem good... also, think mongodb being local or remote should make difference on decision? and exact problem is? i assume have in mysql | key | language | text | it's trivial translate mongodb like { key: ...., translations : { 'de' : , 'en' : , }

i'd set redirect/rewrite in .htaccess following: a few samples of redirects i'm trying accomplish: domain.com/08/04/10/file.php domain.com/new/file.php domain.com/06/01/11/file2.php domain.com/new/file2.php domain.com/07/12/07/file3.php domain.com/new/file3.php you idea. don't know start - there many sub-directories , sub-sub-directories head spinning. want them go /new/filename.php. there 3 subdirectories i'm trying redirect; /06/, /07/, , /08/. each has 2 levels below it, , few php files in 3rd level. suggestions on how start? rewriterule ^/([0-9]{2})/([0-9]{2})/([0-9]{2})/(.*)$ new/$4?d=$1,$2,$3 [l,r] this should turn first second. /01/02/03/myfile.php /new/myfile.php?d=01,02,03 i've assumed need folder names parameters in php call, , folders numeric, 2 characters, looks strangely 2-char-per-part data format ... if that's not case, let me know.

we storing financial data in sql server database using decimal data type , need 6-8 digits of precision in decimal. when value through our data access layer our c# server, coming decimal data type. due design constraints beyond control, needs converted. converting string isn't problem. converting double ms documentation says "[converting decimal double] can produce round-off errors because double-precision floating-point number has fewer significant digits decimal." as double (or string) can round 2 decimal places after calculations done, "right" way decimal conversion ensure don't lose precision before rounding? the conversion won't produce errors within first 8 digits. double has 15-16 digits of precision - less 28-29 of decimal , enough purposes sounds of it. you should put in place sort of plan avoid using double in future, - it's unsuitable datatype financial calculations.

i writing bookmarklets here , have questions related built-in javascript functions. let's want replace built-in prompt function (not in bookmarklet). seems easy enough, there way call builtin prompt function within replacement? prompt = function(message){ var tmp = prompt(message); hook(tmp); return tmp; } i couldn't scoping work out right; example yields infinite recursion. also there way restore default behavior of builtin javascript function has been replaced (without hanging on reference). (function () { var old_prompt = prompt; prompt = function (msg) { var tmp = old_prompt(msg); hook(tmp); return tmp; }; prompt.restore = function () { prompt = old_prompt; } // analogous other functions want replace })(); wrapping in (self-executing) function ensures old_prompt doesn't leak outside. need expose something though. chose provide function doing restoring, convenience , perhaps, 1 say, future-...

assume book , author aggregate roots in model. in read model have table authorsandbooks list of authors , books joined book.authorid when bookadded event fired want receive author data create new authorsandbooks line. because book aggregate root, information author doesn't included in bookadded event. , cannot include because author root doesn't have getters (according guidelines of examples , posts cqrs , event sourcing). usually receive 2 types of answers on question: enrich domain event data need in event handlers. said cannot aggregates roots. use available data view model . i.e. load author view model , use build authorsandbooks row. the last 1 has problems concurrency. author data can not available in view model @ time bookadded event handling. what approach use solve this? thank you. as general advice, let event handlers idempotent , make sure can deal out of order message handling (either re-queuing or building in mechanisms f...

is there way test both 0 , null 1 equality operator? i realize this: where field = 0 or field null but life hundred times easier if work: where field in (0, null) (btw, why doesn't work?) i've read converting null 0 in select statement (with coalesce). framework i'm using make unpleasant. realize oddly specific, there way test 0 , null 1 predicate? it not work because field in(0,null) equivalent of field = 0 or field = null opposed field = 0 or field null . 1 option use case expression: case when field = 0 1 when field null 1 end = 1 the better option stick original field = 0 or field null makes intent clearer.

greetings, i'm looking @ matt gallagher's macro creating singleton classes. http://cocoawithlove.com/2008/11/singletons-appdelegates-and-top-level.html basically, have app multiple views , want able access "global" data each of these views using singleton class. i have 3 strings want access in class: nsstring *uname, nsstring *details , nsstring *selecteddetails. do need make 3 singleton classes static variable in each? also, how , set string variables uname, details , selecteddetails? i'm bit mixed singleton stuff (i encountered such things today!) , wondering if point me in right direction. many in advance, here code i've done: #import <foundation/foundation.h> @interface details : nsobject{ } +(xxx *)sharedxxx; @end #import "details.h" #import "synthesizesingleton.h" @implementation details synthesize_singleton_for_class(xxx); @end do need make 3 singleton classes static variable in each? n...

this not @ familiar with. i want try make simple form 4 edit boxes, 2 @ top, 2 @ bottom, , button. want type couple of things in top 2 boxes related each other. when have them both filled in click on button , saves information in database, preferable external file (doesn't have text, think better if not). can couple of times. saving edit fields database. then when type 1 of words saved in 1 of edit fields @ bottom automatically types other word in last edit field. form should remember connect database every time it's opened when open time can still work edit fields. can advise me on how this? what looking known dictionary, if understand correctly. in other languages known associative array or hash. you going want modern version of delphi, i'd guess 2010 or xe. if can't access you'd need 3rd party library, or home grown based off tstringlist . in fact tstringlist can operate in dictionary mode it's bit clunky. you declare dictionary fo...
