i found previous question on so: n-grams: explanation + 2 applications . op gave example , asked if correct: sentence: "i live in ny." word level bigrams (2 n): "# i', "i live", "live in", "in ny", 'ny #' character level bigrams (2 n): "#i", "i#", "#l", "li", "iv", "ve", "e#", "#i", "in", "n#", "#n", "ny", "y#" when have array of n-gram-parts, drop duplicate ones , add counter each part giving frequency: word level bigrams: [1, 1, 1, 1, 1] character level bigrams: [2, 1, 1, ...] someone in answer section confirmed correct, unfortunately i'm bit lost beyond didn't understand else said! i'm using lingpipe , following tutorial stated should choose value between 7 , 12 - without stating why. what ngram value , how should take account when using tool lingpipe? edit: tutorial: http

i'm on new project , there's lot of warning: function 'yyy' shadows overridable method in base class 'zzz'. override base method, method must declared 'overrides'. i'm wondering if it's safe put overrides. default behavior? there lot of testing done , want minimize problems. changing overrides not same. can add keyword shadows eliminate warning, if have run long time message, changing them override may cause things work differently before. the difference between overrides , shadows shadows not have polymorphic effect overrides does, if call method on base class object, if happens holding child class instance, base class method called. but again, if getting warning, means adding shadows keyword you, throws warning make sure effect want, can eliminate adding keyword yourself. if suspect overrides behavior wanted, can add well, realize not equivalent.

question i having trouble figuring out how create new dataframe column based on values in 2 other columns. need use if/elif/else logic. of documentation , examples have found show if/else logic. here sample of trying do: code df['combo'] = 'mobile' if (df['mobile'] == 'mobile') elif (df['tablet'] =='tablet') 'tablet' else 'other') i open using where() also. having trouble finding right syntax. in cases have multiple branching statements it's best create function accepts row , apply along axis=1 . faster iteration through rows. def func(row): if row['mobile'] == 'mobile': return 'mobile' elif row['tablet'] =='tablet': return 'tablet' else: return 'other' df['combo'] = df.apply(func, axis=1)

why code behave correctly? i've been told multi-line loop bodies should have curly braces public class sample { public static void main(string[] args) { int[] nums = {1,2,3,4,5,6,7,8,9,10}; // print out whether each number // odd or (int num = 0; num < 10; num++) if (num % 2 == 0) system.out.println(num + " even"); else system.out.println(num + " odd"); } } the trick here difference between statement , line . loop bodies execute next statement , unless there curly braces, in case loop execute whole block inside curly braces. (as mentioned in other answers, always practice use curly braces every loop , if statement. makes code easier understand, , easier correctly modify.) to specific example: an if-else statement in java considered single statement. in addition, following valid single-line statement: if(someboolean) someaction(1

i'm trying implement clean-up routine in utility module have. in looking around solutions problem, settled on using weakref callback cleanup. however, i'm concerned won't work expected because of strong reference object within same module. illustrate: foo_lib.py class foo(object): _refs = {} def __init__(self, x): self.x = x self._weak_self = weakref.ref(self, foo._clean) foo._refs[self._weak_self] = x @classmethod def _clean(cls, ref): print 'cleaned %s' % cls._refs[ref] foo = foo() other classes reference foo_lib.foo . did find old document 1.5.1 sort of references concerns ( http://www.python.org/doc/essays/cleanup/ ) nothing makes me comfortable foo released in such way callback triggered reliably. can point me towards docs clear question me? the right thing here explicitly release strong reference @ point, rather counting on shutdown it. in particular, if module released, globals

i have object defined this: function company(announcementid, callback){ this.url = 'https://poit.bolagsverket.se/poit/publiksokkungorelse.do?method=presenterakungorelse&diarienummer_presentera='+announcementid; self = gm_xmlhttprequest({ method: "get", url: this.url, onload: function(data) { self.data = data; callback(); } }) } on callback, wish reference method object called "callbacktest", i'm trying this? var mycompany = new company(announcementid, callbacktest); if anonymous function, have written mycompany.callbacktest() how reference "mycompany" within variables? until reference returned constructor mycompany , can't access argument. so, " anonymous function " alluded way accomplish have access variable, have reference: var mycompany = new company(announcementid, function () { mycompany.callbacktest(); }); or, maybe

i trying configure logback dynamically using hostname setup specific property logger. initialize map following, before appender: def hostname="${hostname}" def logentriestokens = [ "info03": "mytoken" ] and following: appender("logentriesappender",logentriesappender){ encoder(patternlayoutencoder) { pattern = "%d{dd mmm yyyy ; hh:mm:ss.sss} [%thread] %-5level %logger{36} - %msg%n" } token = logentriestokens[hostname] println hostname println logentriestoken println logentriestokens[hostname] println token ssl = false facility = "user" filter(thresholdfilter){ level = error } } and result following: info03 [info03:mytoken] mytoken null for reason, token property not set (i can see investigating appenders hierarchy in java). if instead put constant , such token = "mytoken", works fine. wrong?

is possible compare fields in views using external id (not internal one). need because need hide fields depending on fields. can make work using internal database id. if user chooses example country (in view checks countries id), if id matches in view compared, shows field. example this: <field name="some_field" attrs="{'invisible': [('country_id','!=',10)]}" /> this 1 works, not reliable. imagine if id change (for example installing module id taken other country), show some_field when different country chosen. , not intended. thought using external id, provide when adding data tables in xml files. id static , should same database install module (because id provided in module itself, not created database automatically). there way use same feature, using external id? of course maybe knows better approach solve such problem? p.s. adding field boolean show hide some_field not option, because depends entirely on specific va
