i'm trying make c# software reads information cpu , displays them user (just cpu-z). current problem i've failed find way display cpu frequency. at first tried easy way using win32_processor class . proved efficient, except if cpu overclocked (or underclocked). then, discovered registry contain @ hklm\hardware\description\system\centralprocessor\0 "standard" clock of cpu (even if overclocked). problem in modern cpus, core multiplier decreasing when cpu not need it's full power, cpu frequency changing, value in registry remains same. my next step trying use rdtsc calculate cpu frequency. used c++ because can embed in c# project if method working. found next code @ http://www.codeproject.com/articles/7340/get-the-processor-speed-in-two-simple-ways problem same: program gives me maximum frequency (like in registry value, 1-2 mhz difference) , looks loads cpu more should (i had cpu load spikes). #include "stdafx.h" #include <windows.h>

i've read operations such addition/subtraction linear time, , multiplication n^2 time. why true? isn't addition floor(log n) times, when n smaller operand? same argument goes subtraction, , multiplication, if make program long multiplication instead of adding integers together, shouldn't complexity floor(log a) * floor(log b) , b operands? the answer depends on "n." when addition o(n) , multiplication (with naïve algorithm) o(n^2), n length of number, either in bits or other unit. definition used because arbitrary precision arithmetic implemented operations on lists of "digits" (not base 10). if n number being added or multiplied, complexities log n , (log n)^2 positive n, long numbers stored in log n space.

i seem stuck problem should more obvious me: how can attributes related model show in view. in application there these 2 models: products product_images i'm writing while i'm on go , don't have exact code available. created necessary associations, product has_many product_images , product_image belongs_to product. image model has url, default (boolean) flag , of course product_id. in product index view i'd display default image product. sake of simplicity though let's assume i'm fine showing first picture - conditions should easy introduce once works. so in products index view there's (again, memory): @products.each |p| <h3><%= p.name %></h3> <%= image_tag p.product_images.first.url %> <p><%= p.description %></p> end while description , name of product alone display fine include image_tag view breaks nomethoderror stating url undefined method in class nil. keep simpler got rid of imag

i beginner in java.now i'm facing problem during pratice.actually want string tokens stringtokenizer class , wanna assign these tokens array of string.but i'm getting null pointer exception.my code here. public class token { public static void main(string str[]) { string str1="this first page"; stringtokenizer str2=new stringtokenizer(str1); int i=0; string d[]=null; while(str2.hasmoretokens()) { d[i]=str2.nexttoken(); } system.out.println(d); } } arrays in java must initialized. this: string d[] = null; essentially creates reference array, null. hence nullpointerexception . what more, if initialized, size fixed , array cannot resized . cannot do: string[] d = new string[]; // won't compile: size not specified continuing on, do: d[i] = "whatever"; and i 0. use list<string> instead: list<string> list = new arraylist<>(

i want find hashtags in comment coming db. use regextransformer of solr multivalued field. problem is, transformer delivers first match of string , not matches. boards.xml: <field column="hashtag" sourcecolname="comment" regex="(#[^.!\s]+)" /> schema.xml: <field name="hashtag" type="string" multivalued="true" /> so e.g. "this #good #comment" input should save #good , #comment in multivalued field, #good arrives. i know not best when comes regex, according http://www.regexplanet.com should work intended. ok, found out, behaviour purpose. returns 1 match. solved problem using scripttransformer function commentpieces(row){ var reg = new regexp(/(#[^.!\s]+)/g); var arr = new java.util.arraylist(); while((result = reg.exec(row.get('comment'))) !== null) { if(!arr.contains(result[0])){ arr.add(result[0]); }

at moment i'm working on import script imports bank account data mysql database using php. found mt940 pharser didn't wanted or didn't meet current mt940 standard. wrote own simple class parses me data need. the problem no is, , might not mt940 issue, must filter double transaction. , in basic, simple, if exact same transaction exists in database, don't import again. that's have done. but fun part: transactions might happen twice @ same day. example same transaction twice @ same day [someone might me , send me money twice ;)]. while importing first time, there no problem. in 1 file each transaction transaction. but problem: because transaction not unique (mt940 doesn't send unique's transaction), hard filter out double transaction unique transaction. if have downloaded 2 mt940 files bank account. , 1 of 2 transactions in first file, , 1 in second file. when importing second file, tel me transaction double transaction. so.. i'm struggling th
