this kind of simple problem (or maybe not) i'm caught on. have application testapp uses ui library i'm working on in turn uses graphics library (sharpdx). now sharpdx provides color struct (sharpdx.color). , window class (ui.window) accepts sharpdx.color struct clear rendertarget. however, when using ui library, sharpdx namespace isn't available. causes problem color isn't available. so possible make color available in ui namespace, avoiding need have references sharpdx in project uses ui library. thanks. as far aware, use part of library, need use entire library (unless author has broken down submodules). if using ui library, how can pass sharpdx.color without using sharpdx? if wish use part of library can split off components depend on sharpdx rest. alternatively, can make own color struct, , translate between ui.color , sharpdx.color @ intersection between ui , sharpdx code.

i can't figure out macro means: #define declare_handle(n) typedef struct n##__{int i;}*n declare_handle(hwnd); i have learned c program that: "##" means connect parameter. so macro equals: typedef struct hwnd__{int i;}*hwnd is right? if right, meaning of sentence? ================== code game bombermaaan (for windows , linux), link http://sourceforge.net/p/bombermaaan/code/head/tree/trunk/src/bombermaaan/winreplace.h , line no 90. the main purpose of construct prevent misuse of handles. if handles void * or int or long long or other basic type, there nothing prevent using 1 instead of another. pointer struct hwnd__ , pointer struct hbitmap__ isn't same thing, if have following code: hwnd hwnd; hbitmap hbmp; hbmp = getbitmap(...); hwnd = hbmp; // gives compiler error. it's classic technique ensure unique types api supplier don't want provide true declaration for. although i'm not entirely sure why need ...

when open https://trello.com/board/board_name/board_id.json , can see within board there nested documents of card, list, actions etc. want know whether 3 main collections trello team talk card, board, member referenced or embedded (nested) within board? they're referenced. responses assembled api don't precisely reflect structure of db. otherwise, board documents grow without bound, wouldn't work out long-lived boards. also, if included member documents in board, we'd have update every single board document member on when updated member's name.

i have huge database (mysql) 7 tables (1000000 record each) use simple queries call information : select * matches match_date='$date' select * countries country_id in (select country_id tournaments id='$id') select * tournaments id='$id' i use indexing columns in clause query being faster bit. does have helping ideas improve speed exponentially? the worst request seems one: select * countries country_id in ( select country_id tournaments id='$id') try use this: select countries.* countries inner join tournaments on countries.country_id=tournaments.country_id , tournaments.id=$id index these columns: countries.country_id tournaments.country_id tournaments.id and better use columns names instead of *.

i wondering when touch db when doing queries. more precisely, when query performed: i have kwargs dic: kwargs = {'name__startswith':'somename','color__iexact':'somecolor'} but name__startswith query, need distinct() . , not color__iexact . i thought, set name__startswith distinct() in loop this: for q in kwargs: if q == 'name__startswith': thing.objects.filter(name__startswith=somename).distinct('id') and query dynamically: allthings = thing.objects.filter(**kwargs) but somehow wrong, seem doing 2 different things here.. how can these 2 queries dynamically? django querysets lazy , actual queries aren't evaluated until use data. allthings = thing.objects.filter(**kwargs) if 'name__startswith' in kwargs: allthings = allthings.distinct('id') no queries should preformed above unitl use data. great filtering queries wish do from docs : querysets lazy – act of creating...
