i have following problem best described in diagram: consider following sequences (can type of sequence: numbers, dates (in case dates), etc.) i find groups of longest contiguous sequence output in latter example, i.e. minimum amount of groups containing longest sequence possible. i thought of going sort of sorting/ordering (min/max doesn't seem of here have empty gaps), first left point right, i'm not sure either. just spit-balling pseudo-code last time coded this: var outputranges = new list<range>(); foreach (var range in inputranges) { // let range.touches(range) define function returns true // iff 2 ranges overlap @ (that is, a.start and/or a.end // between b.start , b.end) var overlaps = outputranges.where(range.touches).tolist(); // if there no overlaps, add output if (!overlaps.any()) { outputranges.add(range); } // if there overlaps, merge them else { outputranges.removeall(overlaps); over

i have 2 spans inline-block display, in responsive mode (for resolution lower 768x1024) need position 1 on top of other set display block wrong 1 on top how can make second span go on top? thanks see if variation helps: http://jsfiddle.net/panchroma/rlskl/ the important bits flipped order of 2 divs in html used css manage layout css /* pull first div right , second left desktop views */ #logincontent{ width:330px; float:right; } #attensions{ width:330px; float:left; } .lgnbtn{ clear:both; } /* tablets , smartphones, remove floats above */ @media (max-width: 790px){ #logincontent{ width:100%; float:inherit; } #attensions{ width:100% float:inherit; } } hope helps!

i have been trying figure out how pull backlinks specific domain. understand search link:domain.com . i realize there multiple posts similar 1 every post uses old api has been discontinued. google search api has been replaced google custom search api , not return anywhere near same results google search. is there api other custom search allow me results. have heard have paid services out there happy use if find links or documents. any appreciated. i don't know there's way want google. using link search ( link:yourdomain.com ) return small subset of links site. can see in practice if search links directly using google. better example comes searching site:yourdomain.com . search alone won't show pages on site. google likes keep curtain pulled entire data set. what need indexes data , lets pull out (presumably seo purposes). best place know of mozscape api . own crawls , build own index. have free tier , same data set powers open site explorer . potenti

one question arised in mind while looking implementation of reentrantlock class. reentrantlock serializable , in documentation says deserialized lock unlocked irrespective of state when serialized. make sense because state lock , unlock based on threads @ runtime (who hold lock) , while de-serialize threads may not available. question : why need lock persist because not store it’s basic state (locked/unlocked) ? right can assume may fairness property of lock. fairness again depending on underlying os if persists lock on 1 platform , deserialized on because (write once , run anywhere) may not work no point in persisting fairness. hope put confusion lock serialization in java. http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/locks/condition.html http://download.java.net/jdk7/archive/b123/docs/api/java/util/concurrent/locks/reentrantlock.html i reason why lock persists you're able serialize objects depend on lock itself. if lock wasn't seriali

i have many files in folder. want concatenate these files single file. example cat * > final_file; increase disk space. there way can hardlink files final_file? example ln * final_file. this not possible using links. if need kind of feature , can not afford create 1 large file go custom file system driver. fuse allow write simple file system driver runs in user space , allows access files 1 large file. you write custom block device (e.g. emulating nbd "network block device" protocol) combines 2 or more files 1 large block device. getting know concrete use case give better answer.

i wonder if it's possible map child class property base class table. have 2 classes (shortened): public abstract class user { [key] public int userid { get; set; } public string username { get; set; } // other properties... } and public class customer : user { public int shopid { get; set; } public virtual shop shop { get; set; } // other properties... } i'm using tpt (table per type) inheritance (that means 2 tables - user , customer). reasons have shopid property in user table, other properties customer class in customer table. possible? having shopid column in user table allow example create unique index on username , shopid (the application multi-tenant don't want globally unique usernames, shop-level unique usernames). is you're looking for? userbase.cs public abstract class userbase { public int userid { get; set; } public string username { get; set; } public int shopid { get; set; } publ

i'm using vmware player , blackberry 10 simulator image; need unit/integration tests automatically. know can use vix api spin new simulator , load blackberry image. what love able send 'key presses', launch specific apps, , perhaps send gestures. on android there's monkeyrunner , other similar apps. haven't found respect bb10, know it's new can't 1 request. also, how powerful telnet option? can telnet emulator , change directory apps dir, can't list contents, sudo, or run anything. *****update******* i've made progress wrt this, not much. seems can use windows api send mouse_evt messages vmware emulator; it's not 100% reliable works enough open apps. big hole have right being able detect state after action/swipe/touch executed, aka "did swipe execute work? in right app?". hugely beneficial query device's process list, 'devuser' account given in telnet example can't anything. this gist has basics how touch ,
