gcd (a1, a2, ...) computes gcd of elements a1(1), a2(1), ... . being elements stored in vector a , how compute gcd (a) ? (i mean, gcd (4, 2, 8) = 2 , gcd ([4, 2, 8] raise error in gnu octave 4.0.0). with cell array expansion here one-liner, valid in octave (thanks nirvana-msu pointing out matlab's limitation): a = [10 25 15]; gcd(num2cell(a){:}) # ans = 5 this use cell array expansion, bit hidden there : accessing multiple elements of cell array ‘{’ , ‘}’ operators result in comma separated list of requested elements so here a{:} interpreted a(1), a(2), a(3) , , gcd(a{:}) gcd(a(1), a(2), a(3)) performance still under octave a = 3:259; tic; gcd(num2cell(a){:}); toc elapsed time 0.000228882 seconds. while gcd_vect in @nirvana_msu answer, tic; gcd_vect(a); toc elapsed time 0.0184669 seconds. this because using recursion implies high performance penalty (at least under octave). , more 256 elements in a, recursion limit exhausted.

assume have protocol like protocol typedstring : customstringconvertible, equatable, hashable { } func == <s : typedstring, t : typedstring> (lhs : t, rhs : s) -> bool { return lhs.description == rhs.description } i want able provide default implementation of hashable : extension typedstring { var hashvalue = { return self.description.hashvalue } } but problem error use of unresolved identifier self . how create default implementation of hashable using string representation given description property defined in customstringconvertible protocol? the motivation want create shallow wrappers around strings, can semantically type-check code. example instead of writing func login (u : string, p : string) -> bool instead write func login (u : username, p : password) -> bool (failable) initialisers username , password validation. example might write struct username : typedstring { let description : string init?(username : string) {

i have problem using column-based storage feature in sql server 2012 out lot. there bunch of people using earlier versions of sql server won't able upgrade. in theory, possible create table works optimally on both? i'm hoping client running sql server reports work both against 2012 columnar instance , non-columnar standard instance table difference 2012 1 faster. is doable? what need watch out when reading/writing massive amounts of data in storage-type agnostic way? thanks it's possible have sql queries compatible both earlier version of sql , 2012. things should fine unless using deprecated functionality in earlier versions or new features 2012 (you'd know if were). here's link microsoft's summary of changes in sql 2012 might need watch out http://technet.microsoft.com/en-us/library/cc707787.aspx .

i working calender class , more need 12 months 2 numbers. if use following code: int month = (mycalendar.get(calendar.month)) +1; this different months: 1,2,3,4,5,6,7,8,9,10,11,12 but need is: 01,02,03,04,05,06,07,08,09,10,11,12 this beacuse need make substrings , go wrong if number of ints get. there easy way fix this? i use if statement , check if whole date 5 numbers, add 0 , 3 position, feels cumberstone. the reason loading "1" instead of "01" because stored in int , following if statement: string smonth = ""; if (month < 10) { smonth = "0"+string.valueof(month); } else { smonth = string.valueof(month); } then use smonth instead of month .

it mentioned on msdn link following .find() method if entity not found in context query sent database find entity there. null returned if entity not found in context or in database. find different using query in 2 significant ways: • round-trip database made if entity given key not found in context. • find return entities in added state. is, find return entities have been added context have not yet been saved database. but can cause problem? let's object marked added state, before saving database exception occurred. find might return object added state, have not been saved database later on. second concern, if .find found object in context , object updated in database after finding it, object version on context old? so benefits can using .find() instead of doing search based on primary key using .where or .firstordefault(a=>a.primarykey ==id) ? well docs state find... uses primary key value attempt find entity tracked co

i using go-sql-driver/mysql insert ton of movies omdb data dump. parsing data , inserting following code: _, err = database.query("insert `movies` (`name`, `year`, `release_date`, `full_plot`, `genre`, `imdb_id`) values (?, ?, ?, ?, ?, ?)", movie.name, movie.year, movie.releasedate, movie.fullplot, movie.genre, movie.imdbid) if err != nil { return false, nil } return true, nil it works, 150 rows. doing wrong? your code seems discard error value returned, shouldn't do; handle gracefully. see error is, if you're opening many connections db, should use database connection pool , set (*db) setmaxopenconns value. (*db)query typically used select statements return rows, use (*db)exec or (*stmt)exec insert . i'd advise using db connection pool, , (*sql.db)prepare prepare statement , run inserts (even concurrently) using prepared statement. see https://golang.org/pkg/database/sql/#db.prepare
