aloha! while reading kotling language reference noticed keyword "private" properties of class never used (always default public). said getters , setters generated automatically. created class , made fields private. however, when create object of class, cannot see fields , no setters , getters available, unless write them myself. what's rule here? leave visibility modifier default (public) or make them private , provide mutator methods? thank you. the whole idea of property encapsulates field , accessors in single entity. if need able access , modify property of class outside, should keep property public. if need able read outside not update it, can define public property private accessor. changing default accessor custom 1 not affect clients of class, because under hood compiler generate accessor methods, , clients of class use methods , not access underlying field directly. you should never write explicit getter or mutator methods separate property acces

i use axios ajax requests , reactjs + flux render ui. in app there third side timeline (reactjs component). timeline can managed mouse's scroll. app sends ajax request actual data after scroll event. problem processing of request @ server can more slow next scroll event. in case app can have several (2-3 usually) requests deprecated because user scrolls further. problem because every time @ receiving of new data timeline begins redraw. (because it's reactjs + flux) because of this, user sees movement of timeline , forth several times. easiest way solve problem, abort previous ajax request in jquery . example: $(document).ready( var xhr; var fn = function(){ if(xhr && xhr.readystate != 4){ xhr.abort(); } xhr = $.ajax({ url: 'ajax/progress.ftl', success: function(data) { //do } }); }; var interval = setinterval(fn, 500); ); how cancel/ab

i answered question: concate primary keys in sql there encountered strange behaviour: select 5 + '-' + 8 returns 13 select cast('-' int) returns 0, explains above... but: why single hyphen casted 0 implictly? btw: it's same single + or (multi-)blank string... this related cast hyphen (-) decimal points fact, cast decimal not bring these results... i'm writing answer because it's long/complex comment - it's based off comments. note - not have official source, no confirmation logic "what's implemented". (but makes sense think :)) but suppose you're writing conversion function, needs perform. so have string validate - example cast('-50' int); take each character on own: `-` valid part of conversion, move next character. `5` valid part of conversion, move next character. `0` valid part of conversion, move next character. done. so supposed string cast('-' int); : `-` valid p

in linear model 𝑦 = 𝑎0 + 𝑎1 × 𝑥i + 𝑎2 × 𝑥j + 𝑎3 × 𝑥k + 𝜖 , values 𝑖,j,k ∈ [1,100] results in model highest r-squared? the data set consists of 100 independent variables , 1 dependent variable. each variable has 50 observations. my guess loop through possible combinations of 3 variables , compare r-squared each combination. way have done python is: import itertools itr import pandas pd import time t sklearn import linear_model lm start = t.time() #linear regression model lr = lm.linearregression() #import data data = pd.read_csv('csv_file') #all possible combinations of 3 variables combs = [comb comb in itr.combinations(range(1, 101), 3)] target = data.iloc[:,0] hi_r2 = 0 comb in combs: variables = data.iloc[:, comb] r2 = lr.fit(variables, target).score(variables, target) if r2 > hi_r2: hi_r2 = r2 indices = comb end = t.time() time = float((end-start)/60) print 'variables: {}\nr2 = {:.2f}\ntime: {:.1f} mins'.form

i have django project, , in places have multiline comments indented follows: field = models.integerfield(default=0, null=true) # 0-initial_email_sent # 1-second_email_sent # 2-third_email_sent this violates pep, but, in opinion, helps readability. of course, put comments this: # 0-initial_email_sent # 1-second_email_sent # 2-third_email_sent field = models.integerfield(default=0, null=true) , rather prefer first one. is there way indent comments such without violating pep? magic numbers evil, best documentation here use named (pseudo) constants: initial_email_sent = 0 second_email_sent = 1 third_email_sent = 2 field = models.integerfield(default=initial_email_sent, null=true) as general rule, less have comment better (clear code needs no or very few comments). for more general answer place comments, specially multiline ones: having comments before comm

if want represent view controller's state single struct , implement undo mechanism, how change, say, 1 property on struct and, @ same time, copy of the previous state? struct { let a: int let b: int init(a: int = 2, b: int = 3) { self.a = self.b = b } } let state = a() now want copy of state b = 4. how can without constructing new object , having specify value every property? note, while use placeholder values constants a , b not able construct instance of a other values placeholders. write initializer instead. may write custom method change value in struct also: struct { let a: int let b: int init(a: int = 2, b: int = 3) { self.a = self.b = b } func changevalues(a: int? = nil, b: int? = nil) -> { return a(a: ?? self.a, b: b ?? self.b) } } let state = a() let state2 = state.changevalues(b: 4)

in switch statement, can specify default return value if none of other cases apply. i'd similar std::map, i'm not sure if possible: can make map return specific value/entry instead of map::end if no key fits search? example (here i'd ultimatively - aware code doesn't work): std::map<std::string, void* (*) (dataobject*)> commands; //mapping functions keys commands["test"] = function(dataobject d){dosomething();} commands[nothing else applies] = function(dataobject d){dosomethingelse();} commands.find("test")(somedataobject); // dosomething(); happens commands.find("blabla")(somedataobject); //dosomethingelse(); happens because no other entry found would possible? (also, way i'm using function pointers in example doesn't work @ - can use cpp11's lambda expressions accomplish want do?) i not want use switch clause, nor want if(m.find(x) != m.end()) clause, nor want more if-else's. you can use own

i attending online course cs50 on edx , have assignment in have create program user enters keyword ( used encryption ) , string needs encrypted in vigenere cipher. vigenere works encrypting text following keyword: example if string "hello" , keyword "abc" : a equal 0 in alphabetical characters, b 1, , c 2; letter h in string encrypted without switching characters ( s letter a in keyword = 0), letter e switched 1 position , encrypted f , , on. if keyword has length less of string (like in case) encryption has use again first character of keyword , problem. in fact, think implemented whole program not sure how take consideration if keyword has less characters string entered. program returning first char of string encrypted , first char not encrypted , stops. i not ask complete solution, want understand how can solve program problem. here program: #include <stdio.h> #include <cs50.h> #include <ctype.h> #include <stdlib.h> #in

i have image size 480x360 , displaying in uiimageview frame (0, 0, 320, 568) aspectfill . when touch image view, location says (150,120) . how can map location in original image (480x360) format? thanks you calculate proportions , apply them touch location point. cgfloat _x = imageview.image.size.width / imageview.frame.size.width; cgfloat _y = imageview.image.size.height / imageview.frame.size.height; //assuming p - cgpoint received touch event cgpoint locationinimageview = cgpointmake(p.x * _x, p.y * _y);

i trying reduce gc overhead size. i noticed have several of keys bundle directly assigned string @ start of code , uses assignment later. example: string newtimekey = "newtimekey"; is better if store string in resource xml , call @ start of program this? string newtimekey = getstring(r.string.newtimekey);
