normally start new mercurial project: cd /project-directory hg init this uses username set somewhere on machine ( %userprofile%\mercurial.ini ) but on occasion want initialize project different username. is there option use hg init this? hg init doesn't use username @ (repo starts no changesets, @ revision null ). if want commit different username, use hg commit --user . you can set username in repository's hgrc ( .hg/hgrc ), in global 1 — commits repository use it.

does know, how make jquery work in ckeditor plugin ? created plugin , loaded in ckconfig.jsp ckeditor.config.extraplugins = 'myplugin'; but problem jquery-1.4.4.min load liferay-plugins.xml (or in theme entire portal) isn't loaded in global context when plugin executes. can use jquery everywhere within portal successfully, not in ckeditor plugin. initialization of ckeditor kinda complex , don't see how it. the ckeditor.jsp, included tag, contains entire html document etc. third party javascripts, available ckeditor, included in ckeditor.jsp's head section. so should follows (ckeditor.jsp): <script type="text/javascript" src="ckeditor/ckeditor.js"></script> <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.js"></script> and jquery available ckeditor plugins.

i've been reading on functional programming lot recently, , decided best way understand start using it. spent time looking @ different reviews of functional languages, , think i've settled on haskell because of supposed elegance , fact seems go-to pure functional language. i've been coding in java, python, , perl, figure exercise might pick language forces me use functional programming ideas rather scala or lisp supports imperative programming (but if has thoughts or opinions this, i'd love hear them). anyway, whole point learning ideas of functional programming (for me @ least) i've heard problems more naturally solved in way. , i've found it's better learn new things applying them somehow rather going through mindless tutorials. so, being said, straightforward problems/projects can learn essence of functional programming? try working through project euler challenges. harder go, tackling them 1 one functional programming point-of-view wa...

i face common case of having extract information in remote server via httppost request. imagine in case of weather app retrieving weather info. the server send long inputstream , interested in extracting information stream. keep in mind in memory-cpu bound environment. we have 2 options: 1) use json or xml parser extract informations. this recommended method, has disadvantages: it painfully verbose, if want little information big stream. it should faster , more garbage collection-friendly, i'm not sure case aforementioned case (little information big stream). 2) use simple string manipulation (ssm): we reduce dimension of inputstream grossly trimming off useless infos, , extract informations compact string. purpose, can build filters using static methods, reduce work of garbage collector. also method has disadvantages: i think method discouraged the more informations extract, slower method is. think there critical point in performance curve ssm becomes ...

i have 3 activities in activity stack, (main) -> b -> c. a starts b starts c. my c dialog box 1 button take me , 1 button take me b. activity b must therefore have history, if c calls finish() end in b. given this, how (efficiently) set up? i.e. how (efficiently) go c a? i assume want finish() b if user selects button on c. have b start c result ( startactivityforresult() ) , have c send b result. if result "go a", b can finish().

so quick question how make tchar* (or wchar_t macro) work char*? i using unicode character set. the code problem is: tchar* d3ddevtypetostring(d3ddevtype devtype) { switch (devtype) { case d3ddevtype_hal: return text("d3ddevtype_hal"); case d3ddevtype_sw: return text("d3ddevtype_sw"); case d3ddevtype_ref: return text("d3ddevtype_ref"); default: return text("unknown devtype"); } } the obvious solution change tchar* char* keep tchar* if possible. thanks. and yes using unicode character set. then cannot make tchar compatible char. because if you're using ucs, tchar wchar_t. type char not related in way wchar_t . work convert string (using e.g. widechartomultibyte ), you'd lose unicode support.
