i trying crawl links website use download manager download files. i've tried: wget --wait=20 --limit-rate=20k -r -p -u mozilla "www.mywebsite.com" i can't figure out how use wget or regular expressions save desired links only! wget offers wide variety of options fine tuning files download in recursive crawl. here few options can interest you: --accept-regex urlregex download url matching urlregex . urlregex regular expression matched against complete url. --reject-regex urlregex ignore url matching urlregex . urlregex regular expression matched against complete url. -l tells wget follow relative links. relative links example: <a href="foo.gif"> <a href="foo/bar.gif"> <a href="../foo/bar.gif"> non relative links: <a href="/foo.gif"> <a href="/foo/bar.gif"> <a href="http://www.server.com/foo/bar.gif"> references wget : re

i downloaded eclipse kepler (version 4.3), , first thing did install google plugin eclipse (android, gwt, etc.). since there isn't version of plugin kepler, how reliable install , use plugin version designed juno (4.2)? it work fine, there no major differences, supported versions preferred eclipse backward compatible , don't see issue there.

i wondering if there difference between using java.io , system.io both can achieve same stuff. there difference between java.io , system.io . system.io namespace comes .net bcl. the system.io namespace contains types allow reading , writing files , data streams, , types provide basic file , directory support. whereas java.io package available part of jdk. java.io package provides classes system input , output through data streams, serialization , file system. since system.io part of bcl can use of classes in io operations across platforms each platform has different directory structure, , different filesystem capabilities - example xamarin.ios , xamarin.android support most system.iofunctionality.

in python, there way of decorating function such can add additional functionality before and/or after function. in simple form, looks this: from random import systemrandom time import time import functools rdev = systemrandom() def time_function(func): @functools.wraps(func) def run(*args, **kwargs): start = time() ret = func(*args, **kwargs) print("took {:0.5f}s".format(time()-start)) return ret return run @time_function def foo(): x = [rdev.randint(1, 1000) _ in range(10000)] sorted(x) foo() # prints "took 0.04239s" i wanted write similar functionality in c++. pass function arbitrary parameters , return types function , have perform action. came with: #ifndef timeit_h #define timeit_h #include <string> #include <functional> #include <iostream> #if defined(_win32) #include <windows.h> namespace timeit { unsigned long gettime(void) { return gettickcount(); } }

wcout.imbue(std::locale("chs")); wchar_t *a = l"☻"; wcout << *a; it's not work, why? should do? possible errors: your compiler possibly not recognising l"☻" unicode string in source file. your console doesn't support it you use unicode character code instead ( "\u263b" ). make sure console supports unicode , font has corresponding character it. it may easier (depending on compiler support) use unicode character literals c++ 11; char a[] = u8"my \u263b character"; cout << a;

i have create table , added latest version of footable work fine. when adding font awesome icons item(td) nothing happening, not accepting code either way inject in: html: <td>a-kasse hk <i class="fa fa-check" aria-hidden="true"></i></td> using css: .icon { position: relative; .accepted:before { content: '\25ae'; font-family: fontawesome; left:-5px; position:absolute; top:0; } } so far removing footable initiation script display font awesome icons, not great solution. can include icons anywhere else on page, not in table. anyone have come across problem? the solution suggested here edit css file , replace font-specific code font-awesome or similar css. file @ : https://github.com/bradvin/footable/blob/v2/css/footable.core.css (sry, link have answered it, not accepted, included entire post...)

is java2d rendering mode in processing in pgraphics objects can displayed transparent background (as opposed p2d , p3d )? have tried rewriting code in other 2 modes ( p3d , p2d ) backgrounds of pgraphics turn out opaque (black default)---perhaps i'm missing method turn them transparent? png s i'm displaying in pgraphics objects turning out transparent expected; it's backgrounds of pgraphics opaque. working on project , have selected java2d in order keep pgraphics transparent, wonder if can alternately use p3d , features instead. from looking around online believe java2d mode render pgraphics transparent in earlier versions of processing (1.*), , i'm wondering if has changed version 2? thanks in advance clarification , help! update: below sample of code (written in eclipse in java processing component). v.k.'s reply works great (with png s) in processing pde, i've been unsuccessful getting work in project in eclipse. thoughts? : main class

i'd know if there way add methods library classes using groovy traits. from read here @mixin used this, or can use runtime mixin approach metaclass. since @mixin deprecated in favor of traits, chance achieve same behavior using traits or runtime mixin option? thank you groovy supports implementing traits dynamically @ runtime. allows "decorate" existing object using trait. you can decorate object, however, afraid not possible decorate class instances have method available. see below simple example may or find more details here . trait { string extra() { "i'm method" } } class { string dosomething() { 'something' } } def s = new something() assert s.extra() == "i'm method" assert s.dosomething() == 'something'

i want perform operations on windowedstream in flink, average. there limited operations available predefined sum, min, max etc. val windowedstream = valuestream .keyby(0) .timewindow(time.minutes(5)) .sum(2) //change average? suppose want find average, how can that? flink not have built-in function compute average on windowstream . have implement custom windowfunction this. the efficient way implement reducefunction compute count , sum of value average , subsequent windowfunction takes result of reducefunction , computes average. using reducefunction more efficient, because flink applies directly on incoming values. hence aggregates values on fly , not collect them in window. significantlyy reduces memory footprint of window. since output of reducefunction has same type input, need add field count before applying reducefunction . something following should trick: val valuestream

given list of zeros , boundary elements (ones) there efficient way replace zeros, if less n of them appear between ones? for n=3: [1,0,0,1,1,1,0,0,0,1,0,0,0] => [1,1,1,1,1,1,0,0,0,1,0,0,0] some more cases: [1,0,0,1] => [1,1,1,1] [0,0,1] => [0,0,1] [1,0,0] => [1,0,0] you can convert list str , use replace method, convert list : data = [1, 0, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0] n = 3 repl = (("1" + "0" * + "1", "1" + "1" * + "1") in range(1, n)) data_str = "".join(str(i) in data) r in repl: while true: new_str = data_str.replace(r[0], r[1]) if new_str == data_str: break else: data_str = new_str new_data = list(int(s) s in data_str) print(new_data) this print [1, 1, 1, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0] it looks little convoluted works fine if have small lists not cause memory issues.
