i'm scheme newbie , trying make sense of homework. i've function made earlier called duplicate , , looks this: ( define ( duplicate lis ) (if (null? lis) '()) ((cons (car lis) (cons (car lis) (duplicate (cdr lis)))) )) a typical i/o i: (duplicate '(1 2 3 4)) o: (1 1 2 2 3 3 4 4), basicly duplicates in list. moving on: i'm supposed make function that's called comp . it's supposed built this: (define (comp f g) (lambda (x) (f (g (x)))) where input '(1 2 3 4) , return (1 1 4 4 9 9 16 16) so f = duplicate , g = lambda . know lambda should this: (lambda (x) (* x x)) but here's problem starts, i've spent several hours on this, , can see not made progress. any appreciated. best regards. use map : > (map (lambda (x) (* x x)) (duplicate '(1 2 3 4))) => (1 1 4 4 9 9 16 16) or, modify duplicate take procedure second argument , apply each element of list: (define (duplicate lst p) ...

i need create function variable number of parameters using new function() constructor. this: args = ['a', 'b']; body = 'return(a + b);'; myfunc = new function(args, body); is possible without eval() ? thank much, guys! actually, a+b not primary concern. i'm working on code process , expand templates , needed pass unknown (and variable) number of arguments function introduced local variables. for example, if template contains: <span> =a </span> i need output value of parameter a . is, if user declared expanding function var expand = tplcompile('template', a, b, c) and calls expand(4, 2, 1) i need substitute =a 4 . , yes, i'm aware function similar eval() , runs slow don't have other choice. you can using apply() : args = ['a', 'b', 'return(a + b);']; myfunc = function.apply(null, args); without new operator, function gives same result. can use array functions ...

i have create table can sorted clicking on table header , reordering single , multiple rows hand. i made buttons move selected rows in table model up, down, top or bottom. buttons alter table model , afterwards update jtable. alone works fine. but when start sorting rows clicking on columns in table header goes wrong. manual sorting works collection in table model, sorting clicking header works kind of table view. is there way move rows manually in table view , not in table models collection? or there other better solution? the jtable api addresses relationship between model , view co-ordinates respect sorting. in particular, says, "in examples area, there demonstration of sorting algorithm making use of technique interpose yet coordinate system order of rows changed, rather order of columns." might compare you're doing relevant example in sorting , filtering .

i'm developing , android application. i have model on blender , want export use opengl es 1.1. on android. how can export model set of points , vertex? is there other suitable format use opengl es 1.1? i'm not using rendering engine. thanks. you can use wavefront (.obj) export, , put assets directory of project. there few different .obj importers sample code available on web. 1 of them earth live wallpaper here . from studying code, looks me index buffer unnecessary, , earth wallpaper using draw arrays instead of draw buffers, because none of vertices reused. i suppose expand on code identify identical vertices , merge them, might slow down load time lot.

just personal style, guess, hate having 2 files wcf services. tend copy/paste interface .cs file have deal single file. any dangers in doing this? not dangers per se - there times when useful have separate assembly service, operation , data contracts (just contracts, interfaces, basically) - when need share between server , client side. there's no point in sharing whole service implementation code (the actual service class, implements service interface), client. plus: if have interfaces in separate file (and possibly assembly), makes easier write unit tests, if want mock service. gets bit messy if mix interface , class single file. so consider useful , helpful best practice have separate files interfaces , implementations (actually: 1 class per file only), , put service- , data contracts (and fault contracts) separate assembly.

sorry long introduction before can ask question, think giving background understanding our problem better. we using sql server 2008 our web services backend , time time takes time responding requests supposed run fast, taking more 20 seconds select request queries table has 22 rows. went through many potential areas cause issue indexes stored procedures, triggers etc, , tried optimize whatever can removing indexes not read write or adding nolock our select queries reduce locking of tables (we ok dirty reads). we had our dba's reviewed server , benchmarked components see bottlenecks in cpu, memory or disk subsystem, , found out hardware-wise ok well. , since pikes occurring occasionally, hard reproduce error on production or development because of time when rerun same query yields response times expecting, short, not 1 has been experienced earlier. having said that, have been suspicious i/o although not seem bottleneck. think able reproduce error after running index fragme...

how handle unicode issues in php. set utf-8 parameter function needs or set locale somewhere in bootstrap file once? how affect mysql etc there's no way set global encoding in php. best can is, use mb_ family of functions, , try explicit encoding want use. as mysql, in particular, can make sure connects using utf-8, calling set encoding method/function right after connecting or in constructor if you're using pdo (see http://ar.php.net/manual/en/pdo.construct.php .) using utf-8 php requires discipline, but, it's definitly worth it. hope of helps.

i need compare 2 string in bourne shell of same fixed length. need compare each character against place holder in opposite string , find out how many differences there are. have suggestions on how go this? i after way of number of differences i.e. if compared aab & aac differences 1. this has 100% bourne. if don't mind creating temporary files, can use cmp method. bourne shell pretty limited can do. either use zsh/bash or if sh essential, write c program did want. if creating files every time out of question, create fifos, hackish , ugly, don't it! mkfifo cmp1 mkfifo cmp2 echo "abcd" > cmp1 & echo "abce" > cmp2 & diff_chars=`cmp -l cmp1 cmp2 | wc -l` process substitution in bash or modern shell makes trivial , try use that.

i want generate tool tip dynamically since tooltip has contain grid dynamic number of columns. how do ? you can create new popup , simulate tooltip popup. you have handle 2 events: mouseenter, mouseleave. on mouse enter can have timer open popup after x seconds: private void canvas_mouseenter(object sender, system.windows.input.mouseeventargs e) { timer = new timer(500); timer.elapsed += timer_elapsed; timer.enabled = true; } and on mouse leave cancel timer: private void canvas_mouseleave(object sender, system.windows.input.mouseeventargs e) { timer.elapsed -= timer_elapsed; timer = null; } when timer elapses, you'll use dispatcher open popup: void timer_elapsed(object sender, elapsedeventargs e) { dispatcher.begininvoke(dispatcherpriority.normal, new ooldelegate(opentooltip), true); } the open tooltip method open popup: public void opentooltip(bool isopen) { popup.isopen = isopen; popup.lostfocus += popup_lostfocus; } ...

i have application on corporate intranet makes use of session state store values between wizard (string of pages/ user controls). i'm measuring size of session , navigating around make sure things dotn out of hand. at worst, can size 900 bytes. is much? i know depends on other factors such number of users , amount of memory in server. lets set parameters around these... server allocated 1 gig of ram asp.net (the rest allocated os , other items). have @ 10 users on system concurrently. thanks help personally i'd 900 bytes nothing. lets it's 1kb -> means 1gig of ram should able store 1000k of sessions (not including else). personally think shouldn't @ raw numbers. what's important is: stuff in session meant in session. should put information in session that's useful when user browsing website , can discarded if user leaves website. as long don't store big data objects in session, should fine.
