was trying solve popular interview question - http://www.careercup.com/question?id=3406682 there 2 approaches able grasp - brian kernighan's algo - bits counting algorithm (brian kernighan) in integer time complexity lookup table. i assume when people use lookup table, mean hashmap integer key, , count of number of set bits value. how 1 construct lookup table? use brian's algo to count number of bits first time encounter integer, put in hashtable, , next time encounter integer, retrieve value hashtable? ps: aware of hardware , software api's available perform popcount (integer.bitcount()), in context of interview question, not allowed use methods. integers can directly used index arrays; e.g. have simple array of unsigned 8bit integers containing set-bit-count 0x0001, 0x0002, 0x0003... , array[number_to_test] . you don't need implement hash function map 16 bit integer can order can have function!

as subject says, really. assume have 2 apps, namespaced app_a , app_b . app_a has app_b imported git submodule , autoloaded via composer.json . when call app_b\somemodel->somemethod() from app_a controller , model query database configured in app_b 's config files, or inherit config values app_a ? short answer: won't inherit app_b's config files. expanded answer: app_a loaded it's config files. call app_b\somemodel::somemethod() app_a , app_a's configuration used. have 2 independent applications 'knowledge' of each others state need define communication method between 2 such message queues(mq), http, sockets, streams etc etc. never import app_b submodule of app_a , vice versa unless you're ok app_*'s classes being used in context of loaded application stack. another option @ hmvc or heirarchical mvc pattern. possibly give solution problem without keeping applications separate. there bundle in laravel 3 enabling hmvc hav...

i have assignment , says: you have been provided working program named prime. has 1 input single integer. when “find prime number” button pushed, nth prime number identified. for example: if 4 entered , button clicked, response “the 4th prime number 7” displayed. , if 9 entered, response “the 9th prime number 23” displayed. the program 100% accurate, correct locates nth prime. problem comes in when try find larger prime number. for example: if 10000 entered , button clicked, response “the 10000th prime number 104729” displayed. correct answer; however, took on 48 seconds on i7 computer find solution. imagine how long take find millionth prime number. task analyze problem find more efficient solution make program more useful. first must understand how code provided works. there exercise @ end of document. use run code hand. once understand how works, analyze problem of finding prime number make program operate more efficiently. reason why program slow larg...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .

i have 2 loops creating object: function newimage(){ image = {}; var temp = {} for(i=0;i!=250;i++){ temp[i] = {}; } image = temp; for(i=0;i!=250;i++){ image[i] = temp; } } this should create object 250 values, each being object contains 250 objects. however, creates object creates 250 values, fills 250 values, , loops while. haven't found end of tree, doesn't freeze leading me believe finite. i've checked iterations 50 , works way (it doesn't make long tree). seems if happening during last iterations. here's full thing. var temp = {} for(i=0;i!=250;i++){ temp[i] = {}; } the lines above create object , populate 250 other objects (so far good). then image = temp; sets image (global) variable temp (so image contains 250 objects) then: for(i=0;i!=250;i++){ image[i] = temp; } this replaces each of 250 objects (overwriting previous assignments) reference parent object object has 250 attributes ...

i have shopping cart setup on website using woocommerce , set want achive there create custom radio buttons select option delivery/pickup. if user select pickup option no shipping charged or if user select delivery option $12.00 flat rate/order charged along timings save meta key , value later on creating order. following image elaborate to achieve had created custom plugin stuck add shipping amount. question asked here: can't update shipping amount while checkout in woocommerce(wordpress) but didn't response. appritiated. correct answer posted here can't update shipping amount while checkout in woocommerce(wordpress) using following hook function woo_add_cart_fee() { wc()->cart->add_fee('shipping ', wc()->session->get('ship_val')); } add_action('woocommerce_cart_calculate_fees', 'woo_add_cart_fee'); and date can inserted adding custom field on cart page using add_meta_box()

i have 2 numpy arrays import numpy np x = np.linspace(1e10, 1e12, num=50) # 50 values y = np.linspace(1e5, 1e7, num=50) # 50 values x.shape # output (50,) y.shape # output (50,) i create function returns array shaped (50,50) such first x value x0 evaluated y values, etc. the current function using complicated, let's use easier example. let's function is def func(x,y): return x**2 + y**2 how shape (50,50) array? @ moment, output 50 values. use loop inside array? something like: np.array([[func(x,y) in x] j in y) but without using 2 loops. takes forever run. edit: has been requested share "complicated" function. here goes: there data vector 1d numpy array of 4000 measurements. there "normalized_matrix", shaped (4000,4000)---it nothing special, matrix entry values of integers between 0 , 1, e.g. 0.5567878. these 2 "given" inputs. my function returns matrix multiplication product of transpose(datavector) * matrix *...

i began using two-factor authentication on github, , unable use git on https on private repos in usual way: peter@computer:~$ git clone https://github.com/[...]/myprivaterepo cloning 'myprivaterepo'... username 'https://github.com': [...] password 'https://[...]@github.com': remote: invalid username or password. fatal: authentication failed 'https://github.com/[...]/myprivaterepo/' if disable two-factor authentication can use before: peter@computer:~$ git clone https://github.com/[...]/myprivaterepo cloning 'myprivaterepo'... username 'https://github.com': [...] password 'https://[...]@github.com': remote: counting objects: 147, done. remote: total 147 (delta 0), reused 0 (delta 0), pack-reused 147 receiving objects: 100% (147/147), 22.70 kib | 0 bytes/s, done. resolving deltas: 100% (87/87), done. checking connectivity... done. i know can use ssh , works, there way can keep two-factor authentication while still bein...

i using rcpp write r package, uses c++ code, each time r cmd build <package name> , needs long time compile whole packages, since there couple of cpp files. there way can compile changed files/new files, instead of recompiling everything? thank much! i have makevars file this: pkg_cxxflags=-std=gnu++11 pkg_libs=-l. -lall the best trick know deploy awesome frontend ccache linux distros have, , os x has (in brew iirc). can used both g++ , clang . so in ~/.r/makevars have ver= ccache=ccache cc=$(ccache) gcc$(ver) cxx=$(ccache) g++$(ver) shlib_cxxld=g++$(ver) fc=ccache gfortran$(ver) #fc=gfortran f77=$(ccache) gfortran$(ver) where ver empty 4.9 default. if re-build same package on , over, compile-time fast unchanged code leads object files being retrieved.
