mongodb shard needs know members of replicaset. member list discovery dynamic? mean if add node existing replicaset configured shard on config servers, shard automatically update or have manually update shard configuration new member added replica? in older versions of mongo, prior 2.0.3 of replica set members needed specified when adding shard. seems fair conclude when shard added , needs know 1 of members of replica set, activity between replica set members delegated replica set. probably optimal way sure fire test scenario on own machine. there nothing suggest there additional configuration sharding should required. and bit of update had nothing on having lunch :) spun load of instances mapped out in listed tutorial: http://docs.mongodb.org/manual/tutorial/add-shards-to-shard-cluster/ a few differences being use of sh.addshard in first member of replica set added only, rather members syntax shown in docs. once shards up. added 2 more replica set nodes firstse

android - Java variables declaration -

i little bit confused program flow of android activity, in java main method executes first while in android oncreate methods gets called first, variables defined @ class level? how declared/initialized when activity starts executing, saying oncreate gets called first. can initialize these variables in inner class , use values outside of inner class? actually oncreate() method called first say. activity flows this oncreate - > onstart -> onresume at point activity visible user similarly when activity ends onpause -> onstop -> ondestroy so answering question. variables in class level not dependent, on these methods. because scope whole activity ie; onstart ondestroy . can initialize them in oncreate so. if want change there values on moving next activity should in onresume . activity lifecycle follows you have freedom rest in java

javascript - Declaring Namespaces -

consider: var myapp = myapp || {}; myapp.doalert = function(message) { alert(message); }; myapp.doalert("from myapp"); and (function(ns) { ns.doalert = function(message) { alert(message); }; })(window.myapp2 = window.myapp2 || {}); myapp2.doalert("from myapp2"); they both work, , far can tell, same. purpose being declare namespace. is there benefit 1 style on other? the latter wrapping method(s) in anonymous function, 2 reasons: shorter (abbreviated) reference same thing ( myapp vs ns ). it's wrapped in anonymous function keep further declarations out of global scope. usually see latter more avoid multiple modules defining common variable names (and overriding meaning). see what purpose of wrapping whole javascript files in anonymous functions “(function(){ … })()”?

compiler construction - How does the lexical analyzer identify whether given token is Identifier or Keyword? -

i have basic question on lexical analysis. lexical analyzer (which dfa accepts lexemes , produces token) can produce tokens can identifier([a-z]/[a-z]/[0-9] knowing digit not first char), keywords (if, else,..) , operators & delimiters. so if lexeme 'whil' comes. lexical error stating its not valid keyword or will accepted identifier (variable), lexical analyzer not consider whether syntax right or not ? does lexical analyzer use different dfa identifiers, keywords, operators ? then lexical error stating not valid keyword no. or accepted identifier(variable) yes, , there syntax error parser. as lexical analyzer not consider whether syntax right or not ? the lexical analyser doesn't know syntax. that's parser's job.

bash - awk string inequality seemingly not working -

-
i have file want find lines column 3 , 4 differ. file looks like: chr1:109506687 [t/g] bot top chr1:109506690 [t/g] bot top ... the code use find these lines awk '$3 != $4 {print $0}' cardio-metabo_chip_11395247_a.txt | shuf -n 10 problem using command results rs3218791 [a/c] top top where column 3 , 4 same. when use conditional equality, namely == no output, tells me awk never considers 2 columns $3 , $4 equal, despite them being so. ps. using :set list in vim, file looks like: chr1:109506687^i[t/g]^ibot^itop$ chr1:109506690^i[t/g]^ibot^itop$ .... my awk version gnu awk 3.1.8, can't imagine having anything. should have been right in 1.0 what might wrong? though can't reproduce issue (see below), think you're evaluating values numerically rather strings (all nonempty strings —even "0" — numerically evaluate 1 ). try this: awk '$3 != $4 "" {print $0}' test that concatenate

Trigger all jQuery events bound to an element -

-
i have attached click handler div surrounds radio inputs. when div clicked sets checked state of radio, trigger events bound radio. there multiple modules bind it, , potentially binding on blur, change, click, dblclick, focus, hover etc. now use following code: $('.form-type-radio').click(function(){ $(this).find('input').attr('checked', 'checked').trigger('blur').trigger('change').trigger('click').trigger('dblclick').trigger('focus').trigger('hover'); }); but more succinct method - .trigger('all') perfect. is there way this? or to: demo jsfiddle $('.form-type-radio').click(function (e) { if(e.target != this) return; var input = $(this).find('input')[0], inputevents = $._data(input, 'events'); $.each(inputevents, function (k, o) { $(input).triggerhandler(k); }); }); if div contains more 1 input, use for

Quartz vs Java EE 7 scheduler -

-
i'm java ee developer has used until frameworks quartz schedule tasks. can see java ee 7 features managedscheduledexecutorservice schedule single or repeating tasks. have never used in real projects new features wonder if there still advantages of using quartz (or others) when have portable way ? thanks! i believe in future projects, there's no need use third-party libraries. java ee 7 full of scheduling features. besides new managedscheduledexecutorservice , there's schedule annotation single , periodic repeating tasks , timeout annotation create timers programmatically. imo new managed scheduled service better suited single delayed tasks or create job chain delays betweens specific tasks. you can find more java ee timer service ( schedule , timeout ) java ee 6 or java ee 7 . on side note, if ever try clustering application, it's relatively easy setup schedule -like timers run globally, instead of once per node - plus.

c - Arduino, max array size > 255? -

i'm using arduino-irremote code read in ac unit remote on arduino uno r3. there's unsigned int rawcodes[rawbuf] . when set rawbuf 255 works great. push 256 , uploads fine, there's no response. is memory limitation? according this , it's not. should able ~400 elements. also, because limit i'm hitting 255 makes me believe there's else going on. thanks, justin you shouldn't have limitation. you're playing high amounts of memory. sure have enough available memory so? looks you're talking runtime errors(of memory leak/segfault type) here. you can check total available memory or check this great article (and code) on how debug avr. also if you're using heavy static strings allocation, can reduce memory usage using progmem storage (and having impact on available size sketch).

django calls validate_unique twice - workaround? -

-
i understand validate_unique called when doing full_clean , in turn called when calling modelform.save() - means validate_unique won't automatically called when doing model_instance.save() eg. see answer: https://stackoverflow.com/a/14472335/996792 i do want call validate_unique when calling model_instance.save i've overridden model's save function follows: def save(self, *args, **kwargs): self.validate_unique() super(mymodel, self).save(*args, **kwargs) however, produces following quirk: when saving modelform (eg. in admin), validate_unique called twice! presumably once modelform.save() , once model.save() . is there anyway round inefficiency? i detest unnecessary cruft , sort of thing bothers me. this possible workaround: clean( method called when request comes modelform, set flag when method called: def clean( self ): self.clean_called = true #<---- flag. #other model checks overwrite save( order call valida
