i'm taking on old android project uses viewpagerindicator. i've updated latest version (2.4.1) import statement com.viewpagerindicator.titleprovider not resolving , there code have implements titleprovider. idea methods in titleprovider got moved to? can't seem find documentation. they comment @adrbtk lead me solution. method overriding in titleprovider gettitle(). support library's latest revision has method called getpagetitle() got rid of "implements titleprovider" on method , made code change below. change this @override public string gettitle(int index) { return ((myfragment)getitem(index)).gettablename().touppercase(locale.us); } to this @override public string getpagetitle(int index) { return ((myfragment)getitem(index)).gettablename().touppercase(locale.us); }

how can capture whatever content between integer , successor? example, suppose capture b3c , between 1 , 2 in a1b3c2d . code below gives b3c2d . 'a1b3c2d' =~ / (\d+) (.+) (?{ $1 + 1 }) /x; print $2, "\n"; you need two question marks in construct. 1 puts value of code $^r , returns match 'a1b3c2d' =~ / (\d+) (.+) (??{ $1 + 1 }) /x; print $2, "\n"; output b3c

my question is, when compile c++ program, why put 1 exe file? file become large. use dll libraries shrink size, or there other files can make? want know how make program uses separate files run. (edit) don't want in single file. files become large computer handle it, right? there must way separate files. in java, in class file, seems easier , more efficient. drives fat32 can't have file bigger 4 gigabytes, need more broken down program. looked @ game called portal, exe 100kb , has 100 dll files! to answer question, yes. absolutely can split program separate dll files if you'd like. i've seen developers compile utility functions separate common dll files can included in other projects references. way objects , methods can be called it. in hindsight, compiled code relatively small. binary data consumes space: videos, images, models, sounds, etc. although possible , common smaller programs pack these resources directly executable, isn't idea many obv...

i trying dynamic routing foundation apps, , can't find out how have multiple parameters in route child of child. route be: issues/:issuetype/issuedetail/:issueid and example is: issues/severe/issuedetail/123 in order call 1 of paths in foundation, <a ui-sref="issues({issuetype: 'severe'})"> severe issues </a> my guess (which incorrect) call multiple children parameters is: <a ui-sref="issues({issuetype: 'severe'}).issuedetail({issueid: '123'})"> issue 123 </a> now realize may make more sense call issues/issuedetail/123 rather including first parameter, there case issue id's unique issue type, or there's fact want $stateparams contain both parameters when navigating back. any appreciated! you have state each route. .state( 'issues', { url: '/issues' }, ...) .state( 'issuestype', { url: '/issues/:issuetype' }, ...) .state( 'issuesdetail...

an issue having determining how create security token associated page secure page , hold information visitor. i'd prefer hash function instead of encrypt because faster. optimal method can send url like: /event/1?token=239874dsjakl.jf82374hanfan where token have information in related person clicking link , event? use salts or encryption/decryption worthwhile? you can create table store information associated generated token: class authtoken(models.model): token = models.charfield(max_length=255) user = models.foreignkey(user) used = models.booleanfield(default=false) # add additional fields need store information token # event = models.foreignkey.... to generate random cryptographically secure token, use os.urandom() . work: binascii.hexlify(os.urandom(32)).decode('utf-8') # 64 character string then can use token in url. e.g. /event/1?token=0c5a2774537834e870c2dbab1059eb7358fee7da879e0f14748a35414082ea24

what best way in css without using float property; i know how add icon i'm not sure how add icon before heading , paragraph. an html5/css3 approach use proper markup instead of 1999-style tables, , style them single flexbox reference: section { display:flex; } <section> <figure><img src="//placehold.it/150"></figure> <article> <h2>lorem ipsum</h2> <p>dolor sit amet etc. etc.</p> </article> </section> an added advantage of approach can add flex-direction:column in media query make responsive small screens.

i know blocking code discouraged in node.js because single-threaded. question asking whether or not blocking code acceptable in circumstances. for example, if running express webserver requires mongodb connection, acceptable block event loop until database connection established? assuming pages served express require database query (which fail if mongodb not initialized). another example application requires contents of configuration file before being initializing. there benefit in using fs.readfile on fs.readfilesync in case? is there way work around this? wrapping code in callback or promise best way go? how different using blocking code in above examples? it decide acceptable. , determining consequences of blocking ... on case-by-case basis. analysis take account: how occurs, how long event loop blocked, and the impact blocking in context have on usability 1 . obviously, there ways avoid blocking, these tend add complexity application. really, nee...

i have 2 rdd's, , want computation on rdd2 items each item of rdd1. so, passing rdd2 in user defined function below getting error rdd1 cannot passed in rdd . can know how achieve if want perform operations on 2 rdd's? for example: rdd1.map(line =>function(line,rdd2)) nesting rdds not supported spark, error says. have go around redesigning algorithm. how depends on actual use case, happen in function , it's output. sometimes rdd1.cartesian(rdd2) , doing operations per tuple , reducing key work. sometimes, if have (k,v) type join between both rdd work. if rdd2 small can collect in driver, make broadcast variable , use variable in function instead of rdd2 . @edit: for example's sake let's assume rdds hold strings , function count how many times given record rdd occurs in rdd2 : def function(line: string, rdd: rdd[string]): (string, int) = { (line, rdd.filter(_ == line).count) } this return rdd[(string, int)] . idea1 you c...

i have been learning c++ thinking in c++- bruce eckel , have take so's clear of doubts . of late, have been going through stuffs dealing smart pointers, postfix , prefic overloading , overloading other operators -> , ->* seemed hard nut me hold of. thus, while going through question dynamics of overloading ->* operator , came know lot smart pointers , new library called boost. now, feasible , constructive me start using library when getting hold of c++ knowledge because provides lot of different things shared_pointers etc aren't directly available in c++ standard libraries apart many other optimizations , functions or should stick stick basics of eckel , later go looking boost. know more boost library (the things , bad things involved in using it). in advance as pointed out others, take @ what's newly available in c++11 http://en.wikipedia.org/wiki/c%2b%2b11 . boost huge library depend on specific part of boost had planned make use of.
