i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.

i have 3d coordinate system of track 3 outer points 3d camera. have 3 points in (x,y,z) space. next frame track these 3 points again. use first 3 points initial situation. need draft transformation matrix gives me translation, rotation , scaling of second 3 points, in comparison initial position. now not know how this. there way directly make transformation matrix, or first have work out translation, rotation , scale matrix , make transformation matrix of these three? i work in c++ opencv , qt. got suggestions? not need full working example, can me on way appreciated. thanks! j this tutorial looks pretty nice (what looking called affine transform)!

i'm trying integrate universal image loader android app. has gridview , shows images acquired internet. implemented using arrayadapter loads images in getview() in usual way. it works in terms of displaying picture correctly. found unexpected behavior in loading images memory cache. when activity launched, uil loads image internet or disc cache if exists. (of course, expected behavior.) scrolling down gridview until first column go out screen, , scroll top. in time, images @ first column loaded disc cache, instead of memory cache. then scrolling down , again. in time, images @ first column loaded memory cache. i expect images loaded memory cache @ second time of displaying, step 2 in operation above. don't know why disc cache used in case. here codes. imageloaderconfiguration imageloaderconfiguration mimageloaderconfig = new imageloaderconfiguration.builder(getapplicationcontext()) .defaultdisplayimageoptions(defaultoptions) ...

anyone tinkering python long enough has been bitten (or torn pieces) following issue: def foo(a=[]): a.append(5) return python novices expect function return list 1 element: [5] . result instead different, , astonishing (for novice): >>> foo() [5] >>> foo() [5, 5] >>> foo() [5, 5, 5] >>> foo() [5, 5, 5, 5] >>> foo() a manager of mine once had first encounter feature, , called "a dramatic design flaw" of language. replied behavior had underlying explanation, , indeed puzzling , unexpected if don't understand internals. however, not able answer (to myself) following question: reason binding default argument @ function definition, , not @ function execution? doubt experienced behavior has practical use (who used static variables in c, without breeding bugs?) edit : baczek made interesting example. of comments , utaal's in particular, elaborated further: >>> def a(): ... print("a exec...

i'm writing app uses uiimagepickercontroller let user choose images library. on ipad, shows in popover (because must) controller showing in popover, , you're not allowed show popover popover. can't rework whole app avoid files controller being in popover, i'd push image picker onto files controller's navigation stack. obviously isn't going work stock image picker, there a lot of alternatives . has used of them let me push them onto navigation stack, or need write own? the proper solution present image picker modal view controller existing view controller. set image picker's modalpresentationstyle uimodalpresentationcurrentcontext . this show image picker in same popover modal view controller on calling view controller.

so have matrix report formatting data cells not inherited subtotals. read article ( http://social.msdn.microsoft.com/forums/en-us/sqlreportingservices/thread/d4d21769-2cb0-4bb1-b74b-89e4d31fb724 ) , seems need remove formatting of subtotals , add formatting data cells (i.e. inscope(row_rowgroup1) , such types of formulas). i've never used inscope before thought bothcing syntax. such, tried entering following 1 of data cells , still doesn't come in bold i'd expect. =iif(1=1,"bold","normal") i'm adding fontweight condition on data cell, should bold, right? i'm struggling see why bold data cell (i'm thinking should bold individual rows , subtotals literally nothing bold). i figured out. working, no displaying in preview mode. once deployed functionality desired. sheesh.
