i have function in python takes sign of array (75,150), example. i'm coming matlab , time execution looks more or less same less function. i'm wondering if sign() works , know alternative same. thx, i can't tell if faster or slower matlab, since have no idea numbers you're seeing there (you provided no quantitative data @ all). however, far alternatives go: import numpy np = np.random.randn(75, 150) asign = np.sign(a) testing using %timeit in ipython : in [15]: %timeit np.sign(a) 10000 loops, best of 3: 180 µs per loop because loop on array (and happens inside it) implemented in optimized c code rather generic python code, tends order of magnitude faster—in same ballpark matlab. comparing exact same code numpy vectorized operation vs. python loop: in [276]: %timeit [np.sign(x) x in a] 1000 loops, best of 3: 276 per loop in [277]: %timeit np.sign(a) 10000 loops, best of 3: 63.1 per loop so, 4x fast here.

my ultimate goal load set of propositional formulas in prolog file in order deduce facts. suppose have propositional formula: p implies not(q). in prolog be: not(q) :- p prolog not seem not operator in head of rule. following error: '$record_clause'/2: no permission redefine built-in predicate `not/1' use :- redefine_system_predicate(+head) if redefinition intended i know 2 ways rewrite general formula p implies q . first, use fact contrapositive logically equivalent. p implies q iff not(q) implies not(p) second, use fact p implies q logically equivalent not(p) or q (the truth tables same). the first method leads me current problem. second method conjunction or disjunction. cannot write conjunctions , disjunctions in prolog not facts or rules. what best way around problem can express p implies not(q) ? is possible write propositional formulas in prolog? edit: wish connect results other propositional formulae. suppose have following...

i trying consume web service path object?special=true&id=100 should map specialobject , path object?special=false&id=100 should map regularobject . but when try use pathpattern s of "object?special=true" , "object?special=false" in rkresponsedescriptor s not working - restkit reports url object?special=true&id=100 not match descriptors. is possible specify path pattern use in rkresponsedescriptor incorporates specific parameter value? not really. pattern matching based on path, not parameters. don't think it's possible use parameters during pattern matching. one option use dynamic mapping looks @ url , interprets query parameters decide mapping. another option use metadata while mapping gives access url , parameters contains.

i have array of float numbers: (.25, .45, .15, .27). multiply each element each other divide number of array elements. foreach $element (@array) { $score = $score * $element; } $score = $score/$numofelements; this produces value 0. not sure if syntax correct. your syntax correct, initializing $score variable each time through loop, sets 0 each iteration. move outside loop , should work: my $score = 1 #need initialize 1 multiplying foreach $element (@array) { $score *= $element; } $score = $score/$numofelements; #assuming $numofelements set

let's have function: def func(x, p): return p[0] * x ** 2 + p[1] * x + p[2] and now, can information function using inspect: import inspect args, varargs, varkw, defaults = inspect.getargspec(func) but know have 2 arguments, instead of information on each argument (whether it's scalar or else). just making sure - theoretically, there way can know minimum length of tuple p used in function? thank you! the answer no. firstly can't assume type (let alone size of argument). secondly, there no way tell length, because it's supposed arbitrary , function may nothing input @ all. if want similar, try use *l variable-length arguments. there **d arbitrary map (named arguments).

i'm building application , 1 of requirements use comments one: /// <summary> /// creates new client. /// </summary> /// <param name="uri">the uri.</param> /// <param name="param">the param.</param> /// <returns></returns> i understand it's easy various kind of tools generate docs based on these xmls. decreases code readability, , that's we, humans, trying achieve. could approach replaced other technique in .net? , what's better way improve code readability , cleanness? that information should pop on visual studio when uses intellisense while going through methods. save time since whoever using code not need go code (thus meaning not need expose of code) , see other comments have written. i think documentation, when kept short , point, never bad thing , not affect code readability.

i take screenshot of page displayed in webview. page may contains flash elements , refer google feedback , when take screenshot flash parts of page blank. the flash element(for example video) can not controlled because not own website. beside not want use extension of browser . it's impossible take screenshot of flash elements on webpage using javascript embedded on same page. available js solutions ( more details here ) reading current dom state , rendering (using js render engine implementation) web page on canvas element. flash object executed separate application - flash player. js can't access contents, there no flash render engine implementation in js. however, since mentioned webview , talking flash assume working on native android app. therefore, should easy native app create screenshot ( see this ).

i have requirement route between different pages in mobile app (hybrid) based on output 1 page. routing should configurable, able updated independently of app , ideally able edited visually. server-side handled bpm solutions (jbpm, ibm bpm, etc), on client-side can't find suitable. what need json based set of rules define page route if set of conditions met. example, if on page1 have 2 fields: name , age , user clicks next rules might define if age >= 21 route page2, if age < 21 route page3. is there technology out there this? i've seen there javscript rules engines such nools , aren't bpm-like enough. please don't suggest writing myself - that's being considered. bpm isn't designed "page flow". include sort of page flow technology own uis, don't know of promote feature building uis in other technologies. fundamentally, looking mvc framework. have pages (views) , assumably have model already, looking controller link t...

i have enum: enum myenum{ aaaval1, aaaval2, aaaval3, } i need have abbreviated version of 'myenum' maps every item 'myenum' different values. current approach method translates every item: string translate(myenum myenum) { string result = ""; switch ((int)myenum) { 0: result = "abc"; 1: result = "dft"; default: result = "fsdfds" } return result; } the problem approach every time programmer changes myenum should change translate method. this not way of programming. so.. is there more elegant solution problem? thank :-) four options: decorate enum values attributes, e.g. enum myenum { [description("abc")] aaaval1, [description("dft")] aaaval2, aaaval3, } then can create mapping (like dictionary solution below) via reflection. keep switch statement switch on enum value instead of number bet...

what best way build page in fuelphp each of blocks of page built on own modules , output html put in layout. the best have found far hmvc below. $block1= request::forge('mycontroller/block1')->execute(); $block2= request::forge('mycontroller/block2')->execute(); $data['block1'] =$block1; $data['block2'] = $block2; //assign view browser output return view::forge('home/index', $data); however loading whole framework calls seems rather inefficient (and possibly slow result) . there better way this? if you're using modules (instead of calling different action in same controller seem here), requests absolutely way go. , since requests use routing table, can control controller/action called manipulating routes. setting new request isn't complex, additional delay few milliseconds tops. for completeness, way perform hmvc request: try { $result = \request::forge('your/uri/here')->execute()->respon...
