i'm trying create regex allows unicode letters, digits, -, , apostrophes first character letter or number, while subsequent characters can letters, numbers, -, or '. think regex works fine except in case user enters single letter or number. there anyway make 2+ characters optional? below current regex: /^[\p{l}0-9]+[-\'\p{l}0-9']+$/u thanks! -eric without using ? can use: /^[\p{l}0-9]+[-\'\p{l}0-9']*$/u to allow single alpha-numeric in input since [-\'\p{l}0-9']* means 0 or matches.

after read gordon's article best practices build enterprise application using spring framework, share ideas service layer. my architecture represents gordon described in image http://gordondickens.com/wordpress/wp-content/uploads/2012/07/spring-app-layers.png the application complex, has heavy business rule , demands use different resources database, soap, rest , file handle in same use case. for scenery have described above, have service class needs perform soap , rest requests , handle database data. so, have autowired in service class soap , rest component , repository handle database stuff. i'm concerned if best approach handle integration between services , resources soap, rest, database , etc. thanks so, have autowired in service class soap , rest component , repository handle database stuff. sounds problematic though work. think dependency between layers. service layer depend on repository layer (business logic layer depend on data layer

i can't find documentation explaining subscripting range supposed do. i'd expect yield nth value of range, seems return subscripted value, itself. let range = 10...20 let valuefromrange = range[2] in case, i'd expect valuefromrange equal 12 , it's equal 2 . seems case ranges (or, @ least ranges of type range<int> , range<double> ). is value i'm supposed get? besides defying think commonly expected behavior, behavior useless. you should convert range array if want subscript that: let range = array(10..20) range[2] // returns 12 while can add range.startindex , subscript directly particular range, can't subscript strided ranges @ without converting them: let range = (10..20).by(3) range[2] // error: 'stridedrangegenerator<int>' not have member named 'subscript'

a little basic question can't head around. need create shader works facing ratio shader containing up-down , left-right (in screen space). just this: i want work without having original geometry, having normals, point position , camera position. how should approach this? here's shader: #pragma vertex vert #pragma fragment frag #pragma fragmentoption arb_precision_hint_fastest #include "unitycg.cginc" struct app2vert { float4 position: position; float3 normal: normal; }; struct vert2frag { float4 position: position; float3 normal: texcoord0; }; vert2frag vert(app2vert input) { vert2frag output; output.position = mul(unity_matrix_mvp, input.position); output.normal = mul((float3x3)unity_matrix_it_mv, input.normal); return output; } float4 frag(vert2frag input) : color { float3 normal = normalize(input.normal); float4 output = fixed4(normal.x, normal.y, normal.z, 1.0f); return output; }

question: can give me idea how can write custom algorithm, move object point point b latency? i using pretty simple algorithm: while(input held) add point current existing list of points check if list exceeds maximum offset (a given number of points) -> a.move object on 0 index point. b.delete 0 index point. loop 1. but algorithm not give me desired results.i looking maybe kind of math expression lag simulation, not sure can produced math anyway headed first here ask question. assuming have sort of user input , way process events. one approach explicitly delay user input events (or other events) later time. i.e. when user clicks send game object new position instead of setting new immediate target can put action list of future events "move point b, starting currenttime + delay". as result code not aware of request change destination , continue moving object previous target till "delay" time passed.

i wondering recommend running user upload system s3. plan on using mongodb storing metadata such uploader, size, etc. how should go storing actual file in s3. here of ideas, think best? of these examples involve saving metadata mongodb. 1.should store files in bucket? 2. maybe organize them dates (e.g. 6/8/2014/mypicture.png)? 3.should save them in 1 bucket, added string (such d1jdaz9-mypicture.png) avoid duplicates. 4. or should generate long string folder, , store file in folder. (to retain original file name). e.g. sh8sb36zkj391k4dhqk4n5e4ndsqule6/mypicture.png this depends on how intend use pictures , objects/classes/modules/etc. in code deal retrieving them. if find wanting things - "all user uploads on particular day" - simple naming convention folders year, month , day along folder @ top level user's unique id solve problem. if want ensure uniqueness , avoid collisions in bucket, generate unique string too. however, since you've

i know abstract classes , interfaces in java want know how bring abstraction in working software/project? how thing in such way brings abstraction. your question vague @ best, usage of interfaces helps abstraction because not working concrete types. instance: iprinter p = printerfactory.getprinter(conditions); ... p.print(content); in below line, not aware of what printer using. since using logic, not care. care factory give printer after , print method print content right stream. if want change printer being used, make amendments in factory class different iprinter implementation need (which in case print other media). mean have changed outcome of piece of code without changing of it.

i trying automatically crop image below bounding box. background same colour. have tried answers @ find edges of image , crop in matlab , various applications , examples on mathworks' file exchange stuck @ getting proper boundingbox. i thinking convert image black , white, converting binary , removing that's closer white black, i'm not sure how go it. following answer of shai , present way circumvent regionprops (image processing toolbox) based on find on black-white image. % load img = im2double(imread('http://i.stack.imgur.com/zuiet.jpg')); % black-white image threshold on check how far each pixel "white" bw = sum((1-img).^2, 3) > .5; % show bw image figure; imshow(bw); title('bw image'); % bounding box (first row, first column, number rows, number columns) [row, col] = find(bw); bounding_box = [min(row), min(col), max(row) - min(row) + 1, max(col) - min(col) + 1]; % display rectangle rect = bounding_box([2,1,4,3]); %

scenario there file contains 2 blank lines @ end. when append file, gets written after 2 blank lines (which certain). but want 1 blank line , remove second blank line. in place of second blank line, appending data should written. #-------original file line 1 line 2 [--blank line--] line 3 line 4 [--blank line--] [--blank line--] appending "this line 5" , "this line 6" in above file. what happening right now! #-------original file line 1 line 2 [--blank line--] line 3 line 4 [--blank line--] [--blank line--] line 5 line 6 what want ! #-------original file line 1 line 2 [--blank line--] line 3 line 4 [--blank line--] #only 1 blank line. second blank line should removed line 5 line 6 i have researched , came solution moving file pointer. while appending contents file, file pointer may present after second blank line. work if move file pointer 1 line , append "this line 5" , "this line 6" ? if yes, pl
