i have complicated algorithm requires fitting of quadric set of points. quadric given parametrization (u, v, f(u,v)) , f(u,v) = au^2+bv^2+cuv+du+ev+f . coefficients of f(u,v) function need found since have set of 6 constraints function should obey. problem set of constraints, although yielding problem a*x = b , not behaved guarantee unique solution. thus, cut short, i'd use alglib's facilities somehow either determine a 's pseudoinverse or directly find best fit x vector. apart computing svd, there more direct algorithm implemented in library can solve system in least squares sense (again, apart svd or using naive inv(transpose(a)*a)*transpose(a)*b formula general least squares problems not square matrix? found answer through careful documentation browsing: rmatrixsolvels( a, norows, nocols, b, singularvaluethreshold, info, solverreport, x) the documentation states the singular value threshold clamping threshold sets singular value svd decomposition

rails doesn't offer enum types, need data member can accept 5 values. moreover, want integrated automatically rails forms helper: select_tag . what's right solution situation? p.s, i'd rather not use external plugins, if built-in , neat solution exist. i keep functionality close it's used possible. if values used single model, keep them in model, e.g., if users have possible types, , types, might like: class user < activerecord::base types = %w{guest, paid, admin} # plus validation on `type` field. # maybe plus setter override validates. end when need refer types elsewhere, allowable values in select: user::types there number of valuable tweaks around this, providing decorators make them "human readable" (capitalized, spaced, whatever) or metaprogramming methods allow things like: user.is_guest? # or... user.make_guest! # or... user.guest! i use own small gem functionality because it's case full-blown associ

was watching introductory video - http://www.dartlang.org/dart-tips/dart-tips-ep-2.html , presenter memtioned: production mode gets speed boost ignoring static types, because can avoid many type checks. when static types introduced in actionscript 3.0, static types encouraged means increase execution speed. apparently dynamic types caused vm infer types during execution slow down, , static types, vm cruise through without additional work. why opposite in dart vm? thanks! i'm not sure actionscript i'm guessing in dart, types helpful tool programmers better understand program when shared other programmers (and dart editor provides lots of informative feedback using them). in checked mode (dart's other runtime) compiler slower because going check static types. then, when want use production runtime, skip step hiccup involving types should have been handled (by programmer) in checked mode.

i wanting know if example wanted ask user update software every week example if today friday next friday msgbox pop saying software out of date up-date? is possible????? yes possible. there many ways this. one way might check current date , if friday prompt update. once have prompted keep flag know prompted , friday. once saturday hits can clear asked flag , wait until friday again. method require program running time. store asked flag in configuration file (.ini example) when program updated reopened can check .ini flag no longer available since program updated. another way, many programs , run updater service in background , same thing above except updater updates other program, not (unless update required that). you run updater via windows task scheduler , set run on fridays. way can avoid need keep program running of time.

i don't understand behavior below. numpy arrays can accessed through indexing, [:,1] should equivalent [:][1], or thought. explain why not case? >>> = np.array([[1, 2, 3], [4, 5, 6]]) >>> a[:,1] array([2, 5]) >>> a[:][1] array([4, 5, 6]) thanks! those 2 forms of indexing not same. should use [i, j] , not [i][j] . both work, first faster (see this question ). using 2 indices [i][j] 2 operations. first index , second on result of first operation. [:] returns entire array, first 1 equivalent array[1] . since 1 index passed, assumed refer first dimension (rows), means "get row 1". using 1 compound index [i, j] single operation uses both indexing conditions @ once, array[:, 1] returns "all rows, column 1".

given classes sealed abstract class case class b(param: string) extends case class c(param: int) extends trait z {} class z1 extends z {} class z2 extends z {} def zfor[t <: : manifest]: option[z] = { val z = manifest[t].erasure if (z == classof[b]) { some(new z1) } else if (z == classof[c]) { some(new z2) } else { none } } i think problem pattern matching here impossibility build pattern matching table in bytecode. there workaround on problem? may can use int generated in manifest compiler? the way you've written there isn't robust if have more complicated class hierarchy since if have class d <: c , classof[d] != classof[c] . don't want pattern-match anyway. could; can't call classof[x] in middle of pattern-match, can def zfor[t <: : manifest]: option[z] = { val classb = classof[b] val classc = classof[c] manifest[t].erasure match { case classb => some(new z1) case classc => some(new z2)

how compile? code object playground2 { trait client[s,a] { def wrap[s,a](v: a): (s,a) } class testclient extends client[string, int] { override def wrap[string,int](v: int): (string, int) = ("cache 2.00", v) } } error type mismatch; found : java.lang.string("cache 2.00") required: string here's version of code compiles: object playground2 { trait client[s,a] { def wrap(v: a): (s,a) } class testclient extends client[string, int] { override def wrap(v: int) = ("cache 2.00", v) } } you duplicated types again in wrap function , did not need defined on trait itself.

i writing unit tests backbone app. tests trigger events, causing interference among different tests. here tests test('user setting company should update departmentslists url', function() { var acme = new company({ id:274, name: "acme solutions" }); var companies = new companylist; var departments = new departmentlist; new companyselectorview({ el: '#company-input', collection: companies }); events.trigger('userset:company', acme); equal(_.result(departments, 'url'), 'http://'+document.location.host+'/data/companies/274/departments'); }); asynctest('user setting company should retrieve companys departments', function() { var acme = new company({ id:274, name: "acme solutions" }); var companies = new companylist; var departments = new departmentlist; new companyselectorview({ el: '#company-input', collection: companies }); events.trigger('userset

i have array result of program's input: //1. int i, numberofoccurances; for(i = 0; < numofoccurrances; i++) { printf("%d",printoccurrances[i]); } and example output: 121 now want compare array can print additional statement, example: //2. if (printoccurrances == 121) { printf("this means blah"); } else if (printoccurrances == 232) { printf("this means else"); } //what type of variable should set , how should set @ point 1? //what type of string statement should have @ point 2. thanks assistance. make comparison function , use compound literals @ call site: #include <stdbool.h> bool int_arr_cmp_n(int const * a, int const * b, size_t len) { while (len--) if (*a++ != *b++) return false; return true; } usage: if (int_arr_cmp_n(printoccurrances, (int[]){1,2,1}, 3)) { /* ... */ }

i have multi threaded application treads work on objects fetched using sqlalchemy. objects put in thread queue threads poll from. in main thread doing this: feeds = db_session.query(feed).filter(feed.last_checked <= int(update_time)).all() feed in feeds: self.feed_q.put(feed) and in threads updates feed objects, , keep getting these exceptions when doing updates: programmingerror: (programmingerror) (2014, "commands out of sync; can't run command now") statementerror: can't reconnect until invalid transaction rolled (original cause: invalidrequesterror: can't reconnect until invalid transaction rolled back) i understand has todo threads sharing same db session, don't know how fix this. each thread should have separate database session. you're creating object that's stored in db_session somewhere, perhaps this: db_session = session() essentially, need each thread have own db_session .

i running ssh2 command via php , trying chain commands answer password prompts bash script run. wget url-to-bash-script bash name-of-file.sh after prompt for mysql password: and: retype password: it proceed install packages lamp i have tried no luck; $ssh->exec( "wget url;bash installlamp.sh; password; password"); thanks! what might want use expect here examples on how use it: http://www.thegeekstuff.com/2010/10/expect-examples/

i know trivial implement, want racket live it's "batteries included" promise. looking function works this: > (define (between lst item spot) (append (take lst spot) (cons item (drop lst spot)))) > (between '(1 3) 2 1) '(1 2 3) does racket include such builtin? here implementation based on stephen chang's comment (i swapped argument order little , renamed function too): (define (insert-at lst pos x) (define-values (before after) (split-at lst pos)) (append before (cons x after)))

when set android:minsdkversion="8", following code can't run,and system prompt me set android:minsdkversion="11" set android:minsdkversion="10", code can run correctly, why? thanks! lv.setonitemclicklistener(new onitemclicklistener(){ @override public void onitemclick(adapterview<?> arg0, view arg1, int arg2,long arg3) { selectedandtotal.settext(lv.getcheckeditemcount()+"/"+ lv.getcount()); }}); that method guaranteed work when run on api level 11+ device. normally, method call crash on api level 10 or lower device, throwing verifyerror . if find seems work on api level 10 or lower, indicates getcheckeditemcount() existed on abslistview prior api level 11, had been excluded android sdk (via @hide attribute in android source code). relying upon such methods risky, insofar there no guarantee abslistview on pre-api level 11 devices have method, or method behave on newer devices.

i making simple carousel image gallery. have 2 images , gallery loop first image after last , cannot figure out how functionality working plus previous , next button have stopped working reason. jq/js skills lacking , appreciate working. here jsfiddle of code [1]: http://jsfiddle.net/jsavage/kgaxa/39/ $(document).ready(function () { if (jquery("#gallery").length) { // declare variables var totalimages = jquery("#gallery > li").length, imagewidth = jquery("#gallery > li:first").outerwidth(true), totalwidth = imagewidth * totalimages, visibleimages = math.round(jquery("#gallery-wrapper").width() / imagewidth), visiblewidth = visibleimages * imagewidth, stopposition = (visiblewidth - totalwidth); jquery("#gallery").width(totalwidth); jquery("#gallery-prev").click(function () { if (jquery("#gallery&quo

this ready handling: $(document).ready(function() { $(document).hide(); $('.foo').each(function(elem, i) { $(elem).text('so long , fish'); }); $(document).show(); }}; what i'm trying hiding document until ready on terms, seems show() function doesn't wait elements iteration. by way, tried changing show() , hide() css('display', 'hide') , css('display', 'block') still, can text changing in eyes. how make sure code ran before calling show()? let's suppose fix hiding body or container element. won't trick, , here's why: what happens during time after document (mostly) loaded before hide document? that's right, document may displayed during time despite best efforts. so instead use css class hides, say, body without javascript intervention. example: <!doctype html> <html> <head> <title>test</title> <style

i've got confused @ moment. i've got 1 database developed mlm (multi level marketing) company . so, there's 1 members database.. each member have unique id called membercode.. , members have members under them.. every member have 3 members under him/her.. , 3 members can have same under them.. members added in same database table named "tbmembers" , each member there's "parentid" add member's membercode under whome member is?.. right? now question .. want sql query can go under , under.. 'john doe' having 3 members under him named 'suzan' , 'ellie' , 'smith'. , 'suzan' having 3 members under her.. , same ellie . , example.. 'john doe' having 300 members in down line? , gets paid member adds 3 members under downline, member adds 3 members paid , upline members paid amount of money. can downline level number of member under 1 particular member?? , can calculate earnings based on 3 members joi
