python - Why does put() not work when used with indexed element in Query? -

-
i have issue put() not appear work if access model class indexed member of query directly; however, when explicitly extract class query seems work fine. why this? this code works: class record: field = db.stringproperty() rs = record.all().filter('name = ', name_str) if rs.count() == 1: # assume 1 record in return... r = rs[0] r.field = some_value r.put() and code doesn't (and not raise errors) class record: field = db.stringproperty() rs = record.all().filter('name = ', name_str) if rs.count() == 1: # assume 1 record in return... rs[0].field = some_value rs[0].put() every time index query this, performs query on again, fetches relevant result, decodes it, , returns you. in second snippet, modify 1 instance of entity, discard it, fetch , store (unmodified) second copy. generally, should avoid indexing queries - call .get() or .fetch() instead. for same reason, should avoid using .count() possible, since req...

c# - Correct way to initialize Enums inside a class constructor -

-
i looking @ enums in wrong way want make sure have right theory in how use them. say have enum called colour. enum colour { red, green, blue }; red green , blue represented there 0-255 values. i'm trying initialize enum inside class shape , i'm not sure how go it. public class shape { colour colour; public shape(colour c) { //some attempts @ initialization. //treating object this.colour = c{ 255,255,255 }; //again this.colour.red = c.red this.colour.blue = c.blue this.colour.green = c.green colour.red = c.red? } } } i'm way off in terms of how i'm thinking enums. can give me pointers? in case, might want colour struct instead of enum. in c#, enums single-valued constructs, have 3 values (red, green, , blue). here's might instead: public struct colour { private byte red; private byte green...

visual studio - Is it possible to statically share code between projects in C#? -

is possible, in c#, share code between visual studio projects without needing distribute dll? i'm maintaining software that's composed of few visual studio c# projects, each building simple console executable. there's lot of shared code between projects i'd move out. believe can put code in class library project, i'd rather avoid tacking on dll distribute each of executables. is there way around this? i'm new @ c#, perhaps i'm thinking wrong anyway - there alternate suggestions? you can use ilmerge combine class library exe. http://research.microsoft.com/en-us/people/mbarnett/ilmerge.aspx

c++ - should I use member variable or declare variable inside functions? -

-
i have class ui handle console i/o c++ program. have 4-5 member functions use variable 'string input' cin input, , of these functions recursive. wondering if should declare 'string input' @ beginning of each of these functions, or if better have private member variable , input.clear() @ beginning of each function. what's best choice, style p-o-v , efficiency p-o-v? if string input not persistently associated object in long term, , being used locally in short term, make local variable. 1) it's semantically mean anyway. 2) if you're calling recursively, want separate variables per recursive call, local variables give automatically. 3) efficiency standpoint, a) difference small notice anyway, , b) it's faster create new variable on stack keep pointing @ object's member variable, unless construction of expensive.

forgive me if silly question....but think comp. sci. classes , distinctly remember learning/being quizzed on several sorting algorithms , corresponding 'big o' notation. outside of classroom though, i've never written code sort. when results database, use 'order by'. otherwise, use collection class implements sort. have implemented icomparable allow sorting; i've never gone beyond that. was sorting academic pursuit of don't implement languages/frameworks? or modern languages running on modern hardware make trivial detail worry about? finally, when call .sort on list(of string), example, sort algorithm being used under hood? while might need implement sorting algorithm understanding different algorithms , complexity might in solving more complex problems. finally, when call .sort on list(of string), example, sort algorithm being used under hood? quick sort

i reading on recommender systems on wikipedia , section on "algorithms" seems suggest k nearest neighbour , collaborative filtering based user based algorithm 2 different things. correct? given understanding, aren't both same? if not, differences between them? thanks. not exactly. similar (they share same ideas), there several major differences between them. in fact, article on wikipedia describes 2 distinct ways implement recommender systems, there more of them use idea both these ways. so here's how understood wikipedia article. 1st approach (knn/profiles similarity) first of all, knn not main feature of first approach. it's algorithm find nearest items among whole collection, can used in collaborative filtering well. important idea lies in term "similarity". recommend user in question, find people neighborhood have similar profile. example, want make recommendation user john on facebook. @ fb profile , @ profiles of friends. find ...

javascript - Character representation from hexadecimal -

-
is possible convert hexadecimal value respective ascii character, not using string.fromcharcode method, in javascript? for example: javascript: 0x61 // 97 string.fromcharcode(0x61) // c-like: (char)0x61 // not in fashion, because javascript loosely typed, , not allow 1 define variable's data type. what can do, though, creating shortcut: var char = string.fromcharcode; // copy function variable then can call char instead of string.fromcharcode : char(0x61); // which quite close want (and perhaps more readable/requiring less typing).

quoting pgfsweave manual: how set subdirectories gures , caches? straight out of sweave , cachesweave manuals (nothing new here). figures subdirectory use prefix.string option: \sweaveopts{prefix.string=figs/fig} for caching subdirectory use code chunk @ beginning or document like: <<setup,echo=f>>= setcachedir("cache") @ i find annoying 2 options in different places, r code vs. latex directive. there way set prefix.string option r code, perhaps before sweave called? sweave options can set globally either using \sweaveopts or in call sweave , this: sweave("tmp.rnw", prefix.string="figs/figs")
