say have unorganized directory thousands of files have prefix in names abc-tab, abc-vib, h12-123, h12-498.... how move files same prefix own directory? i thinking using like find . -path '*/support/*abc*' -exec mv "{}" /new/abc\; but means have retype command every prefix. grab prefixes ls , uniq single list, move files using loop. for f in $(ls | cut -d- -f1 | uniq); mkdir "${f}" && mv "${f}"-* "${f}" done many people learn shell scripting advanced bash scripting guide . check out cut , uniq man pages details on programs.

i have coverflow type image gallery have created mobile picture viewing. first iteration lives here: http://codepen.io/jasonmerino/pen/fsloq . i've wired touch events , seems going mobile safari on iphone , ipad, when go view on chrome iphone or ipad images disappear during part of css translate3d moves images sides. i have added -webkit-backface-visibility: hidden; of markup comprises swiper, not fix disappearing act images doing. what missing here? appreciated. thanks! the problem peice of code removing inlined css translate3d . code had in place dealt removing translate re-assigning background images. for (var = 0; < images.length; i++) { $el.images.eq(i).css('style', 'background-image: url(' + images[i].src + ')'); } in mobile safari fine, in chrome images reloaded when re-assigned background image, hence disappearing act. adjusted code little smarter, , concise, removed translate inlined styles. $el.images.css('transfo...

i stuck: how check if user has specified java requirement? need find ranges (for instance java versions between 1.5.0_10 , 1.6.0_10). using javadeploy.js oracle , using versioncheck method can't figure need pass inside versioncheck method ranges such example provided. try this: var lower = deployjava.versioncheck("1.5.0_10+"), higher = deployjava.versioncheck("1.6.0_10+") if (lower && !higher) { // between 1.5.0_10 && 1.6.0_10 } reference: http://docs.oracle.com/javase/tutorial/deployment/deploymentindepth/ensuringjre.html

i'm trying secure accessing specific collection i'm having troubles doing it. have no problems disabling insert, update , delete collection.allow() map. the problem want filter results returned collection.find() , collection.findone() function. read meteor.publish() , meteor.subscribe() stuff, somehow cannot make work (it's not getting filtered, can see results). in server-code following: groups = new meteor.collection("groups"); meteor.publish("mygroups", function() { if (functions.isadmin(userid)) { return groups.find({ sort: { name: 1 } }); } }); the function i'm using works (so it's not it's returning true ). in client-code wrote following: meteor.subscribe("mygroups"); groups = new meteor.collection("groups"); now when groups.find{}); @ client still results (and should no result). am misunderstanding or doing wrong? of course ma...

i'm tring run specific simulation, have code implemented result not 1 i'm expecting, need generate random uniform(ranged 0 1) numbers 10 decimal places (in order convert in other distribution). example: 0,0345637897, 0,3445627876, 0,9776428487 this code: double next = r.next(1000000000, 9999999999); return double.parse(string.format("0.{0}", next)); this should enough: double v = math.round(myrandom.nextdouble(), 10); the difference between 0.123 , 0.1230000000 matter of formatting, see answer @samiam. after edit: double next = r.next(1000000000, 9999999999); return double.parse(string.format("0.{0}", next)); this getting integer between 1000000000 , 9999999999 , uses default culture convert double (in 0 ... 1.0 range). since seem use comma ( , ) decimal separator, @ least use return double.parse(string.format("0.{0}", next), cultureinfo.invariant);

i have collection of models, each of exposes next(...) method moves model forward discrete step. each next() method has parameter given abstract type t. i want able wrap each model class, wrapper inherit type t (which different each model), provide additional logic. trivial letting wrapper extend model, not feasible internal logic of actual model implementations. my solution use type projections so: trait model { type t // works fine when concrete implementation, cannot overridden def next(input : t) = println(input) } abstract class parent { type s <: model type t = s#t val model : s def next(input : t) = model.next(input) } this fails compiler error: type mismatch; found : input.type (with underlying type parent.this.t) required: parent.this.model.t note in concrete implementation of parent, parent.this.t should equal parent.this.model.t. so far workaround abandon using type system, , creating unique parent classes each model (ie duplicating of ...
