i reading tutorial using i/o streams in java , stumbled upon following code inputstream: inputstream input = new fileinputstream("c:\\data\\input-file.txt"); int data = input.read(); while(data != -1){ data = input.read(); } the tutorial mentions inputstream returns 1 byte @ time. if want receive more bytes @ time, possible using different method call? use read(byte[]) overload of read() method. try following: byte[] buffer = new byte[1024]; int bytes_read = 0; while((bytes_read=input.read(buffer))!= -1) { // read bytes here } further can channel inputstream datainputstream more specific tasks reading integers, doubles, strings etc. datainputstream dis=new datainputstream(input); dis.readint(); dis.readutf();

i'm trying put image collection view cell, pretty much. no fancy stuff, image itself, and, well, @ least resized cell size. what doing doesn't compile, though feel pretty confident. context : collection view list of sports, required image. cell holds image , string (the title of sport), , segue page. don't need specific page dynamic, i'll type sports , put images myself, don't need many , no edited, ever. the collection view called typecollection , in .h (hence _ in code) myevent.typepictures 'event' object holding array of images 'typepictures'. this array of pictures in event class : _typepictures = [[nsmutablearray alloc]initwithobjects: [uiimage imagenamed:@"climbing.jpg"], [uiimage imagenamed:@"skydiving.jpg"], [uiimage imagenamed:@"running.jpg"],

for particular program, have abstract superclass several different subclasses. however, i'm having trouble field shadowing illustrated below. abstract class super { string name; string getname() { return name; } } now create subclasses each have own "name". class sub extends super { name = "subclass"; } however, creating instances of subclass, , calling inherited method getname() yield null due field shadowing. is there easy way avoid problem, , allow subclasses each have unique field can accessed inherited method? make field visible in child class , initialize in subclass constructor or in subclass instance initializer.

any appreciated! i wrote module in order keep track of score (<= 99) game written in verilog , runs on led array. want able maintain max score. when current count greater maxcount , maxcount equal current count , else keeps value. the problem is, not know why maxcount changes value whenever count changes (it cannot keep value when count less, instead become less along count ) is there logical error? or there verilog error missed? thank much! module score_keep(clock, reset, pt_0, pt_1, pt_2, pt_3, hex1, hex0, hex3, hex2); input clock, reset; input signed [3:0] pt_0, pt_1, pt_2, pt_3; output [6:0] hex1, hex0, hex3, hex2; wire signed [6:0] count; wire signed [6:0] maxcount; score_counter sc (clock, reset, pt_0, pt_1, pt_2, pt_3, count, maxcount); display(count, maxcount, hex1, hex0, hex3, hex2); endmodule module display (count, maxcount, hex1, hex0, hex3, hex2); input [6:0] count, maxcount; output [6:0] hex1, hex0, hex3, hex2;

how identify new page, or identifier denotes pages number using python-docx? i've looked through docs no avail far , have tried looking wd_break.page attribute feature not yet support. appreciated thanks. the short answer can't reliably determine soft page breaks .docx file. can identify hard page breaks , may able detect word broke pages last time "flowed" document. a word document "flowed" document, meaning word's layout engine "flows" text of document page until runs out of room, creates new page flows remaining text. these "soft" page breaks not specified in .docx file; determined word @ time of rendering, either display or printing. makes sense because whenever change, example, margins, pages may break @ different locations. an implication of .docx file not contain markup identifying following text should flow onto new page. a hard page break 1 explicitly inserted document author cause following content flow

recently started playing around python , came around peculiar in way closures work. consider following code: adders=[0,1,2,3] in [0,1,2,3]: adders[i]=lambda a: i+a print adders[1](3) it builds simple array of functions take single input , return input added number. functions constructed in for loop iterator i runs 0 3 . each of these numbers lambda function created captures i , adds function's input. last line calls second lambda function 3 parameter. surprise output 6 . i expected 4 . reasoning was: in python object , every variable essential pointer it. when creating lambda closures i , expected store pointer integer object pointed i . means when i assigned new integer object shouldn't effect created closures. sadly, inspecting adders array within debugger shows does. lambda functions refer last value of i , 3 , results in adders[1](3) returning 6 . which make me wonder following: what closures capture exactly? what elegant way convince lambda

i want know whether scenario of taking ssh works or not try , except. if try part ask ssh password should move except part. here code, import os,sys,subprocess def process (input): print input = subprocess.popen (input,shell=true,stdout=subprocess.pipe,stderr=subprocess.pipe) output,error = a.communicate() return output,error try: process('ssh system1@123.123.123.123 \'ls\'') except: process('ssh system2@10.101.10.1 \'ssh system1@123.123.123.123 \'ls\' \'') in case not working @ ssh time out. as wrote it won't, because ssh sit there waiting password , not fail. however since not sending input command, can pass -n option ssh , fail if wanted ask anything. -n should work.

i'm building small website both in english (ltr) , hebrew (rtl). the website uses same code base, , changes captions according language being displayed. when english user enters site should see content left right. lets have image text next - image on left , text on right. when hebrew user enters should see image on right , text it's left. is there acceptable way doing in bootstrap without having write same html twice , without overriding bootstrap css classes? if attach js language checkbox, add/remove pull-right class elements want move: example: http://www.bootply.com/fzmcivlvbl# js $('input:checkbox').change(function(){ if($(this).is(":checked")) { $('div.ltr').addclass("pull-right"); } else { $('div.ltr').removeclass("pull-right"); } }); html <div class="col-xs-6 ltr"> <div class="thumbnail"> <img src="http://placeho

i want convert number x of base n string , store in str . str has max size of max . in program don't want use library functions. if reach maximum size of array, function should return false , array contents should undefined. the prototype of function looks this: bool num2str(int x, char *str, unsigned n, unsigned max); how go making work? i'm having trouble understanding algorithm behind it. i need check value of n , did that: bool num2str(int x, char *str, unsigned n, unsigned max) { assert(n >= 2 && n <= 36); return true; } but that's do. please help. let's take number in base 10: 123456. let's repeatedly apply module , integer division using number , base 10: 123456 mod 10 = 6 123456 div 10 = 12345 12345 mod 10 = 5 12345 div 10 = 1234 as can see, module base extracts last digit, while integer division base shifts number on digit right. can same base. hope hint enough.
