in chapter 1 on fixed points, book says can find fixed points of functions using f(x) = f(f(x)) = f(f(f(x))) .... what functions? it doesn't work y = 2y when rewrite y = y/2 works does y need smaller everytime? or there general attributes function has have find fixed points method? what conditions should satisfy work? according banach fixed-point theorem , such point exists iff mapping (function) contraction. means that, example, y=2x doesn't have fixed point , y = 0,999... * x has. in general, if f maps [a,b] [a,b] , |f(x) - f(y)| should equal c * |x - y| 0 <= c < 1 (for x, y [a, b]).

i learning how code on w3schools.com. there explanation on it's not helping. says "defines default address or default target links on page" why need this? you don’t need base element. used when most urls on page refer site other site of page; in case, <base href="..."> lets use relative urls those; other urls must absolute. in past, <base target=...> used on frameset pages in order make link open in particular frame.

i have quick question using xor 2 swap 2 string literals. so have following: #include <stdio.h> #include <stdlib.h> #include <string.h> void intswap(int *a, int *b){ *a=*a^*b; *b=*a^*b; *a=*a^*b; } void swapstring(char **a, char **b){ char *temp=*a; *a=*b; *b=temp; } void main(){ char *s= "ha"; char *t= "oh"; printf("%s , %s \n",s,t); // prints ha oh swapstring(&s,&t); printf("%s , %s \n",s,t); // prints oh ha int a=10; int b=5; printf("%d %d\n",a,b); //print 10 5 intswap(&a,&b); printf("%d %d\n",a,b); //print 5 10 } as can see, used binary operation xor intswap. however, when tried same thing swapstring, it's not working. i error message saying: invalid operands binary ^ (have ‘char *’ , ‘char *’) do know how use xor swap 2 string literals? possible in c? ahead!! there's no bitwise operation

i have cobbled shell script submit multiple jobs on cluster, appears without giving me error message, output files missing , error log files empty. script supposed 1.) make bunch of new directories, 2.) copy 4 files each (mainparams, extraparams, infile, , structurejobsubmissionfile) 3.) submit each 1 cluster run structure while changing 1 parameter in mainparams file every tenth directory (that's 's/changethis/'$k'/g' line). test running on front end gives no errors, structure program date on cluster, , cluster administrators don't see wrong. thanks! #!/bin/bash reps=10 numk=10 k in $(seq $numk); in $(seq $reps); #make folder name (ex. k4rep7) tmpstr="k${k}rep${i}" #echo "making folder , filename $tmpstr" #make new folder mkdir $tmpstr #go folder cd ./$tmpstr #copy in input files cp ../str_in/* ./

i working on issue see intermittent crashes happening @ customer site, while code review, found have written code in destructor free memory etc. question when destruct-or gets called. does called when client call's release on interface. or how free resources consumed interface or when supposed free resources. i know when call relase returns "0" com calls dllcangetunloadnow , dll unloaded , freeing memory? can clarify regards tom typically implementing object's destructor called release if reference count has reached zero. performed implementing object's implementation of release . so, typical implementation of release looks this: ifacemethodimp_(ulong) release() { ulong cref = interlockeddecrement(&_cref); if (!cref) delete this; return cref; }

i have been facing problem several times. ssh amazon ec2 or emr machine using command line , run hive query in interactive mode. shows gradual progress of mapper , reducer phase. but, let's network problem disconnected ec2 or emr machine. now, hive query still running? if, yes can check progress report see on hive console again? so, 3 things can do: use web interface. amazon gives access detailed here run query in screen , if disconnected, reconnect , reattach previous session. can point logging happen file instead of stdout can reopen when log on machine run query using nohup it's not attached session , keep running on own after kicked off. again, pipe logging file rather stdout , check file or tail once log on.

as understand lu factorization, means matrix can written = lu lower-triangular matrix l , upper-triangular matrix u. however, functions in scipy relating lu factorizations ( lu , lu_factor , lu_solve ) seem involve third matrix p, such = plu , p permutation matrix (and l, u before). what point of permutation matrix? if "true" lu factorization possible, why ever have p other identity matrix? consider gaussian elimination process. do if there's 0 on pivot? have switch rows, introduces p matrix. moreso, small non-zero pivot values lead numerical instability in floating point environment. basic algorithms avoid searching entry largest absolute value in pivot column , switching corresponding row pivot row. this switch can expensive, largest absolute value entry have bigger pivot's absolute value factor, e.g. 10, switch occur. reduces number of switches, keeps necessary limit floating point errors. search "lu factorization partial pivoting"

i've seen similar question: destructor vs member function race .. didn't find answer following. suppose have class owning worker thread. destructor of class can like: ~ourclass { ask_the_thread_to_terminate; wait_for_the_thread_to_terminate; .... do_other_things; } the question is: may call ourclass's member functions in worker thread sure these calls done before do_other_things in destructor? yes can. destruction of member variables willonly start after do_other_things completes execution. safe call member functions before object gets destructed.

my question: i have file following: input(1) input(2) input(3) input(6) input(7) output(22) output(23) 10 = nand(1, 3) 11 = nand(3, 6) 16 = nand(2, 11) 19 = nand(11, 7) 22 = nand(10, 16) 23 = nand(16, 19) now, read file , try find word nand . if find word nand want push id (which 10 first line) array. problem: array in want push id of nand should of class node type. how do that? ps: need array of node type because call method processing on 2 nodes e.g. wire(node* a, node*b); that's easy: include header vector: #include <vector> declare vector, of type node : std::vector<node> nodes; and when have created new node object: nodes.push_back(my_new_node); also, can have vector of node* if want manage memory on own. please note, possible address of object ( node ) vector have careful not trust between operations on vector.

is there away set type face views(including list view) @ 1 time, instead of doing each view.thank you can use following method set typeface layouts public void setfont(viewgroup group, typeface font) { int count = group.getchildcount(); view v; (int = 0; < count; i++) { v = group.getchildat(i); if (v instanceof textview || v instanceof edittext || v instanceof button) { ((textview) v).settypeface(font); } else if (v instanceof viewgroup) setfont((viewgroup) v, font); } }
