is tail recursion better forward recursion perfomance in erlang? or erlang compiler optimizes forward recursion too? mean, there reasons use tail recursion instead of forward recursion? in opinion, forward recursion looks more pretty. tail recursion better because uses less memory. bring need onto next call, minimizes memory utilization on stack. also, when tail recursive code optimized, function returns not needed thrown away make faster in cases. for example, if function's return value call function, there no need keep intermediary function on stack. code jumps directly caller inner function. non-tail recursion optimized tail recursion in cases erlang compiler, don't count on it. make habit code tail recursive functions whenever can.

did ever have persuade customers migrating asp.net web forms application 2.0 3.5 necessary? why customers should install new framework? (and new operating system - there lot of windows 2000 machines out there although support ended in 2010 ). which advantages them? security? performances? costs? is reason 2.0 old ? any link appreciated. ps: please don't answer 3.5 has linq, it's advantage developers not customers the advantage here indirectly customer, (hopefully) allowing write code faster/shorter , therefore fewer bugs , more deadlines hit. there may small performance increases newer iterations of franmework.

when used use ado.net, used create tableadapters populated using joined queries, example product table adapter have column 'location' if underlying select query joined product location table. in linq, how accomplish this? return columns in joined query writing linq queries in productsdao class? type returning binding gridview? problem retuning linq results have thought break consistency of productsdao class (this should return product rows db). i think best option define classes represent joined data want return (e.g. productdetails ) , return iqueryable<productdetails> data layer. to return queryable, can write simple linq query: public iqueryable<productdetails> getproducts() { return p in db.products join d in db.details on p.id equals d.id select new productdetails { p.name, d.notes }; } this approach has several benefits: you're not exposing yourdatacontext object directly - can stay private field of dao class

assume user input data below. define matrix cost. matrix created 3 3 matrix. matrix should form this: cost = [c11 c12 c13 c21 c22 c23 c31 c32 c33] since want display set of row, : c1 = cost(1,:); % become c1 = c11 c12 c13 c2 = cost(2,:); % become c2 = c21 c22 c23 c3 = cost(3,:); % become c3 = c31 c32 c33 then want value in matrix. this. c11 = cost(1,1); c12 = cost(1,2); c13 = cost(1,3); c21 = cost(2,1); c22 = cost(2,2); c23 = cost(2,3); c31 = cost(3,1); c32 = cost(3,2); c33 = cost(3,3); so equation want use type of matrix. lambda = ((8*c13*c23*c33*pdt)+(4*c12*c23*c33)+(4*c13*c22*c33)+(4*c13*c23*c32)) ./ (4*c23*c33)+(4*c13*c33)+(4*c13*c23)); so problem is, if want make 4 3 matrix, , generate matrix this: cost = [c11 c12 c13 c21 c22 c23 c31 c32 c33 c41 c42 c43] the equation want use matrix(4 3) quite different. how im gonna it? need use if else statement? or while? can me solve th

just out of curiosity, closures in javascript reference whole "outer environment", or returned function analyzed see variables in outer scope references , gets references those? theoretically, nested function in javascript has access variables in containing scopes. when identifier encountered, resolved against scope chain , list includes objects properties variables , function parameters of each containing execution context (i.e. enclosing function), innermost first, plus global object @ end. function object drags scope chain around wherever goes. however, these variable objects , scope chain specification constructs , not accessible directly, implementations free make whatever optimizations like, including analyzing function code , exposing variables accessed function , functions nested within it, long specification appears satisfied. however, it's best assume if have enormous object accessible via closure function, enormous object going stick around @ lea

coming java, i'm wondering if java best practice applies javascript. in java, there's separation of interface , implementation, , mixing them considered bad practice. same token, recommended hide implementation details of library end developers. for example, log4j 1 of popular logging libraries out there recommended write code slf4j library or commons logging library "wraps" log4j. way, if choose switch logging framework such logback, can without changing code. reason you, user of logging library, how logging done none of concern, long know logging does. so javascript, non-trivial web applications have own custom javascript libraries, many of use open source libraries such jquery , dojo. if custom library depends on, jquery, not extension, implementation, see need add layer wraps jquery , makes transparent rest of javascript code? for example, if have foo library contains custom, front-end logic, you'd introduce bar library wraps jquery. way, foo libra

how can imitate functionality of expandoobject in .net 3.5 application least overhead? best lead far use lin fu framework ( http://www.codeproject.com/kb/cs/linfupart2.aspx ), i'm thinking there may better. to give better idea of going here, objective dynamically create type parameters of methodinfo . so, want turn this: public class serviceobject { public void execute(string transformmeintoaproperty); } into public class serviceobjectexecutesignature { public string transformmeintoaproperty{ get; set;} } at runtime. have able access parameters using reflection, because using linq expressions. you use codedom dynamically compile new types @ runtime. there's upfront cost of doing that....i suppose depends on lifetime of types generating. http://www.codeproject.com/articles/26312/dynamic-code-integration-with-codedom http://www.c-sharpcorner.com/uploadfile/mgold/codedomcalculator08082005003253am/codedomcalcula

possible duplicate: a comprehensive regex phone number validation i've got this. 1?\s*-?\s*(\d{3}|\(\s*\d{3}\s*\))\s*-?\s*\d{3}\s*-?\s*\d{4} it matching lot of phone numbers, it's not catching these two: (123) 456-7890 or 123.456.7890 awhile asked question a regex number of digits in string. answer gave me regex (\d*\d){10}{n} . i've used phone number validation since then. not care format give me phone number in, long contains 10 digits. if care area code + phone number, may work well.

to run c program this bash> gcc test.c -o test and then bash> ./test how can make test.c execute terminal in window?? xterm -e "./test" this execute 'test' in new xterm window. assuming linux of course.

things presence notification needed im messenger apps have. kik , managed improve texting experience many-fold. if web application, comet implementation , run event loop server handle connections , keep either flash/web socket or long polling connection open on client (socket.io ftw). i'm not sure iphone, connections on 3g+wifi , all: - maybe nsurlrequest handles stuff , it's simple keeping long running long polling connection on background thread , register notifications onto it? anyways, appreciate pointers who's implemented realtime on iphone. well i'll respond other peoples' reference: you can use node.js socket.io basically, , implement long polling on iphone. there's library somewhere iirc, it's relatively simple implement yourself: implement state machine of sorts on phone switch between open request , getting data, fire off request. implement heartbeat (you don't want hit http timeout anyways) of 5 seconds, read socket.io

is there way adjust visual-c++ (ms vs 2010 ee) project properties in such way, same .sln files can built in 1 click among different computers (on windows, of course)? - possibly upload visual-c++ projects svn server. project uses libraries (header , .lib files) absolute (system dependent) path (e.g. boost) , it's own utils. you can use environment variables in project settings enclosing them in $(). e.g. if environment defines boost_include: set boost_include=c:\boost\include\boost-1_45 then can use $(boost_include) in settings refer boost include directory.

if have autoreleased object, when retain count (i.e. value returned when call method retaincount on it) decrement? had figured when scope of method object allocated within ended, tests aren't indicating that. have code following: int itemindex = 0; nsarray* items = [mresponse componentsseparatedbystring:@","]; self.mtext = (nsstring*)[items objectatindex:itemindex++]; self.mtext = [mtext gtm_stringbyunescapingfromurlargument]; nslog(@"retain count: %d",[mtext retaincount]); this returns 2 count (mtext has retain property makes sense), , after exiting method, call outside likewise returns 2. don't @ retaincount . it's misleading. long follow memory management programming guide you'll fine. if rephrase question "when default autorelease pool drain?" answer when control flow returns runloop.

i'm implementing algorithms in http://portal.acm.org/citation.cfm?id=1813708 utilize suffix arrays find longest common substrings. algorithms involve constructing suffix array string concatenation of set of given strings string separators called sentinels. example, if given strings a, b , c, new string d created a$1b$2c$3 $1, $2, $3 sentinel characters marking ends of each string. sentinel characters must unique , lexicographically less other characters in a, b , c. my question revolves around representation of sentinel characters in python. if a, b , c ascii strings, i'm thinking might need convert strings utf-8 , shift range 0-127 higher range such there characters available lexicographically less in strings. if seems reasonable, efficient mechanism remapping characters in python such range n-127+n n number of strings provided? i think should use tokenizer , replace each string integer. sentinels, there plenty of integers left over. probably, it's more con

i'm developing web application heavily relies upon knowing exact x , y location of each text character on canvas. problem different browsers aren't rendering each character same scale. the font using courier new , have tested in chrome 9, ff4 beta , chrome 9 beta. i know if there can done. also, due how browser handles text or purely canvas api? i remember article interoperability tests between different browsers. handling of fonts different in each browsers. there differences css , weight or rotation in transform. not think able achieve perfect rendering in each of them

i'm new android development , i'm trying build simple app browse network dlna servers , allow me browse each dlna server directory. thought pretty simple: 1 activity displays dlna servers on network, user selects one, redirect activity browses dlna media server's directories. my question quite basic: how persist information 'selected server', 'current directory' , other things this? need way rest of application know do. should build data service? seems violates common understanding of services should be. how can i/should persist application state? you have few options. 1 think best pass these values in intent object you're sending 1 activity next. therefore, activity browses dlna media server's directories receives selected server in intent, , if came dlna list activity, that's great, intent come other activity wants show media server directories user. try hard encapsulate functionality inside activity doesn't need depend on re

i wondering if point me resources or overviews how x86 extensions made. research in how make custom extension in spirit similar x86-64, have idea may worthwhile (which won't go in @ time, don't ask), not sure information how done or research/learn on how it. thanks, peter architectures, such x86 , x86-64, not written in software, define hardware software runs on. x86 not code, rather, defines instruction set, how memory accessed, registers, etc. the architecture part of processor. literally need design , manufacture new processor make modification architecture itself. out of reach people.

i have check if specific version of flash player 10.2.161.23 installed on client's machine or not javascript code. client's system has many other versions same "major version" 10.1.102.64 etc.. tried following code snippet for(var = 10; > 0; i--) { try { flash = new activexobject("shockwaveflash.shockwaveflash."+string(i)); } catch(e) { alert("in ctach"); } version = flash.getvariable("$version"); alert(version); } client has 10.1.102.64 & 10.2.161.23 on system , above code recognizing only, 10.1.102.64 not recognizing other version same "major version no:". can use new activexobject("macromediaflashpaper.macromediaflashpaper"); instead of shockwaveflash.shockwaveflash . have impact? flash player version want detect 64 bit
