design patterns - Singleton class -

-
we have application, access the config file, have singleton class , object of used. i understand singleton class , provide 1 instance of object. question why can't have opening , closing of config file whenever required. ofcourse, method may expensive since windows need allot handle , dispose off when not in use. are there specific reason using singleton class. thank you, harsha singleton class can pure evil. is. you'll see if ever decide apply loose-coupling code. my advice reconsider design. think of reading config file @ application start , persisting object configuration parameters in memory. can pass object classes/interfaces require config parameters. you may redesign application in way doesn't require numerous writes config file without using singleton (anti)pattern.

java - Session state using guice -

-
i've session scoped state. first idea hold session scoped servlets. bind servlet this bind(foo.class).in(servletscopes.session); but exception javax.servlet.servletexception: servlets must bound singletons. key[type=foo, annotation=[none]] not bound in singleton scope. so servlets can't have scope servletscopes? whats right way deal session state (yeah, of course it's better write state less servlets/classes/applications)? from understanding can bind whatever want session scope, problem in example foo seems subclass of servlet , , servlets must bound in singleton scope. to resolve this, bind state (called bar ) in session scope , give foo constructor provider<bar> argument (which filled in guice) can access session-scoped state singleton-scoped foo servlet.

javascript - How to set cookies in a rails 3 app -

i've added application.js doesn't create cookie. in fact breaks other javascript functions below it. function gettimezone() { var current_time = new date(); var offset = -(current_time.gettimezoneoffset() / 60); cookie.set({timezone: offset}); } gettimezone(); what doing wrong? cookie isn't build in javascript class , don't think it's part of prototype or jquery either. unless you've included javascript defines cookie , i'd that's problem. cookie's bit of pain work in raw javascript i'd recommend using 1 of 2 plugins below make life easier. for prototype: http://jason.pureconcepts.net/articles/javascript_cookie_object for jquery: http://www.electrictoolbox.com/jquery-cookies/

unix - How does shell execute piped commands? -

-
i want understand how shell executes piped commands ? e.g. cat | more. aware executing normal command shell fork, execute , child returns. how shell internally handle execution of piped commands ? considering example cat | grep , shell first forks start cat , , forks once more start grep . before calling 1 of exec* family of functions in 2 newly created processes start 2 programs, tricky part setting pipe , redirecting descriptors. pipe(2) system call used in shell process before forking return pair of descriptors both children inherit - reading end , writing end. the reading end closed in first process ( cat ), , stdout redirected writing end using dup2(2) system call. similarly, writing end in second process ( grep ) closed , stdin redirected reading end again using dup2(2) . this way both programs unaware of pipe because work standard input/output.

android - Does using the ActionBar in Honeycomb really mean i have to create an extra App? -

-
last week began honeycomb update app , since documentation has become available. 1 of big things change in app use of actionbar. little disappointed following sentence doumentation: however, if want use action bar apis, such add tabs or modify action bar styles, need set android:minsdkversion "11", can access actionbar class. does mean have create app if want take advantage of actionbar or there way around this? no, bit of documentation incorrect. need android:targetsdkversion="11" , plus proper settings in options menu xml resource, use action bar. if wish use features of action bar require access methods exist on api level 11 , higher, need take care not execute portion of code on older devices. here sample project put custom view action bar, try configure view on honeycomb or higher. same code works fine on older versions of android, 1.6.

unix - Shell script traversing the all subdirectories and modifying the content of files -

-
i need modify number of files inside directory. need modify files contain particular text , have replace new text. so thought of writing shell script traverse through subdirectories , modify content i'm having problem while traversing possible directories. you can use find traverse through subdirectories looking files , pass them on sed search , replace text. e.g. find /some/directory -type f -name "*.txt" -print -exec sed -i 's/foo/bar/g' {} \; will find txt files , replace foo bar in them. the -i makes sed change files in-place. can supply backup-suffix sed if want files backed before being changed.
