i've got latest xcode xcode 4.6, , have problem: nsarray *array = @[@[@"a",@"b"]]; nslog(@"%d", array[0].count); before run it, xcode told me "property 'count' not found on object of type 'id'". but if change to nslog(@"%d", [array[0] count]); then, fine. so question is, why can't obj-c process two_d_array[index].count ? looks @ docs nsarray . there no count property. in fact, there no properties @ nsarray . when use property syntax non-property method, compiler deal ok if have object of specific type , there method of same name. in case have id . compiler can't safely work out attempt access count property should converted call count method.

android comes in many flavors, of them include built in apps. manufacturers add own apps. i know sounds general question, of apps know of (of google, samsung, lg,...) open source , can learned/tinkered with? more importantly, how can them? as example of apps nice know of source code: google's/samsung's contacts app. google's dialer/phone app. google's camera app. samsung's multi window feature. samsung's locker (keyguard). google's gallery app. google's launcher app. and there many more... maybe offer our improvement in code helping companies make apps better. there opengrok can view code online, , here source code of google contacts: http://androidxref.com/4.2_r1/xref/packages/apps/contacts/ there google camera: http://androidxref.com/4.2_r1/xref/packages/apps/camera/ google gallery: http://androidxref.com/4.2_r1/xref/packages/apps/gallery/ dialer included in contacts , phone: http://androidxref.com/4.2_r1/xr...

my question how i'm supposed around use of pseudo-instructions such la , li . many internet sources use pseudo-instructions anyway, confuses me extent. part of problem going wrong snippet. simulator spits out syntax error liu instruction , don't understand going wrong. from understanding, liu command grabs significant bits, shifts left 16 bits, , puts in register ($a0). ori instruction takes label, , performs or on lower 16 bits adding register. .data m1: .asciiz "some string" .text main: lui $a0, m1 # loads m1 $a0 printed ori $a0, $a0, m1 am not supposed use label m1 liu or ori ? , if i'm not meant to, do instead? i've read this , understand supposed happening, i'm still not sure why instructions has different effect, , why there andi $a0,$a0,0x0000ffff before liu , ori commands. the mips simulator i'm using qtspim if relevant. i've gone looking answers question here , elsewh...

i found statement while studying functional reactive programming, "plugging space leak arrow" hai liu , paul hudak ( page 5) : suppose wish define function repeats argument indefinitely: repeat x = x : repeat x or, in lambdas: repeat = λx → x : repeat x requires o(n) space. can achieve o(1) space writing instead: repeat = λx → let xs = x : xs in xs the difference here seems small hugely prompts space efficiency. why , how happens ? best guess i've made evaluate them hand: r = \x -> x: r x r 3 -> 3: r 3 -> 3: 3: 3: ........ -> [3,3,3,......] as above, need create infinite new thunks these recursion. try evaluate second one: r = \x -> let xs = x:xs in xs r 3 -> let xs = 3:xs in xs -> xs, according definition above: -> 3:xs, xs = 3:xs -> 3:xs:xs, xs = 3:xs in second form xs appears , can shared between every places occurring, guess that's why ca...

there 2 tables following columns: table1 (id1, id2) //pairs (id1, id2) - unique table2 (id2, name) //id2 - auto incrementing, name - string from php have 100-300 pairs (id1, name) have inserted tables following conditions: some (id1, id2) pairs can not yet in table1, 'name' in table2. in case table1 has filled corresponding id1, id2. if (id1, id2) pair in table1 - 'name' in table2 has updated, if not same. how accomplish performance in mind? ps: can not use foreign keys or fuse tables edit: here example, demonstrate logic given 100-300 pairs of (id1,name): id1 | name -------------- 5 | name0 10 | name1 20 | name2 30 | xxxxx tables table1 , table2 either empty or contain records: table1: table2: id1 | id2 id2 | name -------------- ---------------- 5 | 0 0 | name0 | 1 | name1 30 | 2 2 | yyyyy after inser...

is there difference between these 2 commands? git subtree split --prefix=some_subdir -b some_branch and git filter-branch --subdirectory-filter some_subdir some_branch i use git filter-branch instead of git subtree because want delete files in new branch, worried guarantee, true git subtree , might not valid git filter-branch : repeated splits of same history guaranteed identical (ie. produce same commit ids). because of this, if add new commits , re-split, new commits attached commits on top of history generated last time, 'git merge' , friends work expected. filter-branch not give such guarantee, when using on hoping side. subdirectory filter has reproducible results , filter-branch not touch commit information (commit , author timestamp , person). information commit sha created from, filter-branch should generate same history again. that’s going long filter-branch not start making guarantees, , seems unlikely.

i newbie crm , googling how hide , show text field using jscript library in ms crm (online) , found several options of using function setvisible . i tried options: xrm.page.ui.tabs.get('new_fieldname').setvisible(false); xrm.page.data.entity.attributes.get('new_fieldname').setvisible(false); xrm.page.getattribute('new_fieldname').controls.get(0).setvisible(false); but last 1 working. first option gives me error message. what different between them? just add points made.. the difference between xrm.page.ui.tabs.get('new_fieldname').setvisible(false); and xrm.page.getattribute('new_fieldname').controls.get(0).setvisible(false); the first refers tab ( xrm.page.ui.tabs ), second refers attribute ( xrm.page.getattribute ). so if wanted hide whole tab, sections , fields can use first one. if want hide individual field can use xrm.page.getcontrol("new_fieldname").setvisible(false); which shortcut fr...
