i not find docs or examples on how structure app allow different views in same controller use different layouts , stylesheets. our app scaffolded , used nifty-generators generate views, added devise authentication. have views , controllers 2 models: widgets , companies. i have single layout: layouts/application.html.haml, don't see referenced anywhere assume (a rails newbie) it's used naming convention. i need add couple of views (for mobile browsers) have different stylesheet , layout (for example, no login/logout links in top right), within same controllers. how can done? by default, layouts/application.html.haml ( .erb if not using haml). in fact, layout file set per controller or per action, instead of per view, per view folder. there few cases: to change default layout file controller (ie. use another.html.haml instead of application.html.haml ) class applicationcontroller < actioncontroller::base layout "another" # way l

i need simulate http post programatically, i.e., need generate request post variables , send page. to clarify, need simulate behaviour of regular post, not whole thing programatically. need fill in request in same way filled if form post happening, , send browser page expects post. here 1 way it. you send method url , name/value parameters in form of namevaluecollection. method makes http post on endpoint , returns response string. of course depending on what/why you're doing , how many times method called, there maybe other alternatives. until provide more information on specific needs, method enough. the method below uses tasks (.net 4.0) , async methods faster synchronous method next code listing if you're making multiple calls in loop example. static string getwebresponse(string url, namevaluecollection parameters) { var httpwebrequest = (httpwebrequest)webrequest.create(url); httpwebrequest.contenttype = "application/x-www-form-urlencoded&qu

actionscript's array , vector classes both have slice() method. if don't pass parameters, new array or vector duplicate (shallow clone) of original vector. what mean "shallow clone"? specifically, difference between array newarray = oldarray.slice(); vector.<foo> newvector = oldvector.slice(); and array newarray = oldarray; vector.<foo> newvector = oldvector; ? also, if vector's base type isn't foo, simple , immutable int? update: what result of following? var one:vector.<string> = new vector.<string>() one.push("something"); one.push("something else"); var two:vector.<string> = one.slice(); one.push("and thing"); two.push("and last thing"); trace(one); // something, else, , thing trace(two); // something, else, , last thing thanks! ♥ in context, .slice() make copy of vector, newarray refers different object oldarray , except both seem identical objects.

as far know isn't possible. i draw outline around text flowing around floated picture on web page. css or javascript tricks appreciated. horrible mockup: http://i.stack.imgur.com/wf7bw.png . edit: this link demo aloha editor give idea of purpose of outline: http://www.aloha-editor.org/demos/wordpress-demo/ why? in cms i'm working on, users can edit information in contenteditable divs on front end of website. in situation above having outline around entire div create confusion user cannot edit black block. currently have been adding class create outline around content can edited. worked @ first, got little creative formatting (e.g. no margin on bottom of div, content wrapped in div outline) things started getting hacky , ugly. if there way wrap text of div nicely spaced outline , apply consistently on site make things easier. plus i'm @ impasse content structure outlined above. i'm open other ideas besides outline convey users text can edited

i trying copy deleted file previous version svn repository working directory. i know file present in revision r xxx , because svn log -v , can see old revision number associated file. i svn info find repository name in case of form svn+ssh://repository i svn copy -r xxx svn+ssh://repository name/filename ./filename but complains svn: file not found by default when specify url of file in repository, svn assumes you're referring object in head . command means: locate 'filename' in head trace history of file revision xxx copy file looked then, current directory of course, fails @ first step since file no longer exists in head. need explicitly reference object used called filename in revision xxx , using what's known "peg revision": svn copy -r xxx svn+ssh://repository/filename@xxx ./filename the svn book has a more in-depth explanation of peg revisions , if you're feeling brave...

the blackberry webworks sdk tablet os build tool generates archive contains files , manifest.mf entry each file , base64 encoded sha512 digest. however, there bug many files in build cause build failure. trying figure out how generate same information myself. the example below comes manifest.mf , contains filename , digest. however, base64 variant uses _ instead of / , - instead of + , has no trailing == padding. archive-asset-name: air/xx/img_0999.jpg archive-asset-sha-512-digest: yi_kxwjpjwwsi5mdqpebqc9svi-bh6zyq5pgbd3jqiqhu-r-5hv8a0yh_y5j2t9mpyz5tvmw4jxhsxnympv1ta i running windows 7, have git installed have mingw32 bash shell. found piped combination of openssl , tr commands seems bit of kludge. openssl dgst -sha512 -binary img_0999.gif | openssl enc -base64 | tr '+' '-' | tr '/' '_' | tr -d '=' | tr -d '\n' is there better way generate digest? eventually, have images in directory tree. hoping script soluti

can python code used java using jython, without modifying python code in way prevent working correctly in cpython? if yes, steps have taken (in java code)? if not, reasons cannot done (so far)? python modules can depend on python versions (e.g. python 3 vs python 2 , may require minimum python version (e.g. 2.6) in case of using dedicated language features introduced in python version) python modules may depend on c extensions won't work jython python modules may use cpython features not available in jython in general: python-only code should work jython - in cases: have test, test, test. written modules provide unittests - should try run tests jython , see what's happening.

take django instance, in manage.py : try: import settings except importerror: sys.stderr.write("error: can't find file 'settings.py'...") seems legit, happens when settings imports non_existant_lib_foo ? well, you're sent on goose chase possible things have done path , etc. of course can use except importerror e: , print out actual error message, if want catch specific error , give bit of advice, above? you're left using regexp more or less or, @ best, guessing "right" module failed importing, , display message. is there better way handle this? basically problem error message wrong - there other reasons why import can fail, not wrong paths. importerror means "you cannot use module, @ traceback find out why", jumped conclusion. if want display "can't find file" should file first. imp.find_module that.

in class work, i've done successfully, in simple programs. today, had more complex program, , eclipse did horrible borky things after defined debug symbol, , these horrible things did not go away after removed definition. i've been told source symbol debug in used gcc compiler, , interfering standard library defining myself. is okay use #define debug myself? or not? yes, ok define symbol debug yourself. not ok define symbol _debug (note leading underscore): symbols beginning underscore , capital letter, or 2 underscores, reserved use implementation (that is, compiler , toolchain). since reserved, should not define them yourself, can test existence. see §7.1.3 of c99 standard. another symbol aware of ndebug , free define or not define, if define before inclusion of <assert.h> , causes assert statements removed.
