i working android studio 2.2. if have resources (xml files, example) have errors in them, when try build these errors bring entire build screeching halt, even if not referencing them activity. don't want delete files directories because eventually fix them, not priority @ moment. how in world can "turn them off" now, or @ least tell build system ignore them? tried doing "keep.xml" tools:discard trick adding paths, doesn't when compiling debug target. way can project build either deleting files out of resources or moving them. seems overkill. lintoptions { abortonerror false } adding in app gradle file force complete build errors in it. or, can comment files.

i want aggregate indices of dataframe groupby function. word count 0 3 1 5 2 3 3 2 4 1 what want pd.series consists of list(descending order) of indices, word [2, 0] [3] [4, 1] i've tried built-in functions groupby, however, couldn't find way aggregate indices. provide hint or solution problem? i think can first change order of index [::-1] , groupby , apply index list . last sort_index : print (df[::-1].groupby('word', sort=false).apply(lambda x: x.index.tolist()).sort_index()) word [2, 0] [3] [4, 1] dtype: object another similar solution: print (df.sort_index(ascending=false) .groupby('word', sort=false) .apply(lambda x: x.index.tolist()) .sort_index()) word [2, 0] [3] [4, 1] dtype: object

i'm kind of self-programmer-made-man, i'm missing basic knowledge time time. that's why i'm unable define topic of question, because don't know how name , how works (but know answer seem trivial many of you). when know what's you're looking it's lot easier find answers. in objective-c, can see lines of code : aclassname *myobject = (aclassname *)[nsentitydescription insertnewobjectforentityforname:@"aclassname" inmanagedobjectcontext:app.managedobjectcontext]; what's bother me (aclass *) part. what's ? i know/feel it's related basic knowledge can't name can't find it. my guess (and that's how use now) that's used calling class methods (+) i'm not sure of , may more deep understand. thanks explanation. it's cast, in case down cast (even because casts implicit). a cast operation developer while writing code hint compiler type narrower 1 compiler thinking about. think following s

i tried vertically center inline-block this: div { width: 50px; height: 50px; background: red; line-height: 50px; } span { display: inline-block; width: 20px; height: 20px; background: white; } <div> <span></span> </div> but span not vertically centered. why? because line-height sets position of baseline of text (the bottom end of span ). since span 20px high must add half of line-height : div { width: 50px; height: 50px; background: red; line-height: 60px; } span { display: inline-block; width: 20px; height: 20px; background: white; } <div> <span></span> </div>

i have server 32 logical cores(16 physical cores , hyper-thread enabled) , have 8 redis instances on it. seems 16 cores, id 0 7 , 16 23, used , other 16 cores idled. shows cpu affinity mask redis process ffffffff(from taskset -p pid). so wonder cpu affinity has been set automatically in redis? thanks leo no, redis doesn't set cpu affinity . think misunderstand output of taskset command. the affinity mask got, i.e. ffffffff , means process might running on of processors. , that's default behavior. can test starting process doesn't set cpu affinity, e.g. vim xxx.conf , , use taskset check mask. should return ffffffff . in order make process running on specific cpu, can run following command: taskset -pc 0 process_id , i.e. running on 0th processor.

i have bit of code looping through select boxes on page , binding .hover event them bit of twiddling width on mouse on/off . this happens on page ready , works fine. the problem have select boxes add via ajax or dom after initial loop won't have event bound. i have found plugin ( jquery live query plugin ), before add 5k pages plugin, want see if knows way this, either jquery directly or option. as of jquery 1.7 should use jquery.fn.on : $(staticancestors).on(eventname, dynamicchild, function() {}); prior this , recommended approach use live() : $(selector).live( eventname, function(){} ); however, live() deprecated in 1.7 in favour of on() , , removed in 1.9. live() signature: $(selector).live( eventname, function(){} ); ... can replaced following on() signature: $(document).on( eventname, selector, function(){} ); for example, if page dynamically creating elements class name dosomething bind event parent exists, document . $(document
