if you're writing library, or app, unit test files go? it's nice separate test files main app code, it's awkward put them "tests" subdirectory inside of app root directory, because makes harder import modules you'll testing. is there best practice here? for file module.py , unit test should called test_module.py , following pythonic naming conventions. there several commonly accepted places put test_module.py : in same directory module.py . in ../tests/test_module.py (at same level code directory). in tests/test_module.py (one level under code directory). i prefer #1 simplicity of finding tests , importing them. whatever build system you're using can configured run files starting test_ . actually, default unittest pattern used test discovery test*.py .

if have uilabel linked xib file, need release on dealloc of view? reason ask because don't alloc it, makes me think don't need release either? eg (in header): iboutlet uilabel *lblexample; in implementation: ....

i'm building dsl form validation in python, , 1 of requirements able specify field should greater or less constant or field value. result, i'm trying map operators < , > , <= , >= equivalent functions in operator module, can called during field validation. i realise create dictionary map operator function, there nicer way it? there way access python's built-in mapping? as far i'm aware, there no built-in dictionary mapping string ">" function operator.lt , etc. as others have pointed out, python interpreter not make use of such dictionary, since process of parsing , executing python code first translate character sequence ">" token representing operator, translated bytecode, , result of executing bytecode execute __lt__ method directly, rather via operator.lt function.

i writing paint program in delphi. user clicks 2 points on screen , line drawn between them. want lines anti-aliased. put code in create() procedure of opengl class (which called 1 time in start): glenable(gl_line_smooth); glenable(gl_blend); glblendfunc(gl_src_alpha, gl_one_minus_src_alpha); glhint(gl_line_smooth_hint, gl_nicest); when start drawing, first, second , maybe third lines drawn fine. interestingly enough, when number of lines increases (say 7, 8 lines), anti-aliasing starts fail! adding each line on screen, gets worse , lines edges starts become sawtooth!! i put same code on top of draw() procedure draws lines (and runs each click of mouse), nothing changes. am doing wrong here? has suggestion? are sure you're not drawing line segment more once? call glclear before doing drawing?

i have table in don't want specify primary key, after inserting records in using linq...aahhh...its giving error "can't perform create, update or delete operations on 'table(abc)' because has no primary key" can ani 1 tell me how insert record without setting primary key. way im not setting primary key because table have bulk of data keep. you can't use linq-to-sql directly tables don't have primary keys, because it's not supported. if you're worried performance hit of indexing, can add stored procedure insert , add data context. it's bit more work, , it's not linq-to-sql, it'll method on call on data context. there won't noticeable performance hit on identity primary key field anyway.

i started playing around yaml-cpp, managed build , run of examples yaml-cpp wiki can't find way save emitter file. is not possible? mean pyyaml library has 'dump' function this. there no such functionality in yaml-cpp? there workaround converting yaml emitter stl stream , dumping yaml file? please let me know thanks, adam the function emitter::c_str() returns null -terminated c-style string (which not have release), can write file. example: yaml::emitter emitter; emitter << "hello world!"; std::ofstream fout("file.yaml"); fout << emitter.c_str(); there emitter::size() , returns number of bytes in string, in case want more advanced , don't want walk string find length. if want dump node stream, there's shortcut: yaml::node node = ...; std::ofstream fout("file.yaml"); fout << node;

creating new excel workbook in: dim xl excel.application dim wb excel.workbook set xl = new excel.application xl.visible = false set wb = xl.workbooks.add is there easy way stop excel automatically creating sheet1, sheet2, sheet3? i can delete these unwanted sheets afterwards feels clunky solution. xl.sheetsinnewworkbook = 1 more information on msdn (scroll down add method applies workbooks object. ) full code: dim xl excel.application dim wb excel.workbook dim restoresheetsinnewworkbook long set xl = new excel.application restoresheetsinnewworkbook = xl.sheetsinnewworkbook xl.sheetsinnewworkbook = 1 set wb = xl.workbooks.add xl.sheetsinnewworkbook = restoresheetsinnewworkbook 'or set 3'

i want insert createdby, modifiedby, createdate, modifieddate columns in every database table manage user activity. this first time try this. there best practice follow? design pattern manage this? my first thought in business logic layer, , in every business classes' insert , update method, this: class.createdate = datetime.now; or class.modifieddate= datetime.now; class.modifiedby = currentuser.id; or class.createdby = currentuser.id; or there better way? bryan this depends on types of business objects managing, , rules around create/modified data needed for. in cases, database audit trail, , there no need information in business logic layer. in case, information should live @ database level only. if using orm, might mean keep data objects anyway. if using stored procs, need know how take user name tag record with. datetimes can handled setting default value of getdate() on column.
