@ http://www.artima.com/pins1ed/builtin-control-structures.html#7.7 , see following code val = 1; { val = 2 println(a) } println(a) where says semicolon required here, why? from rule @ http://www.artima.com/pins1ed/classes-and-objects.html#4.2 , think semicolon should auto added since val = 1 can legal statement. the next line begins { , think can start legal statement. (since there's no compile error if add semicolon , separate first 2 lines 2 statements.) val = 1 not in parentheses or brackets. because legal call apply : implicit class richint(i: int) { def apply(thunk: => unit) = 33 } val = 1 { val = 2 println(a) } println(a) // 33 ! 1 { ... } short 1.apply {...} . apply not defined int default, implicit enrichment shows, possible. edit : semicolon inference conditions described in '§1.2 newline characters' of scala language specification . inferred semicolon called 'special token " nl "' in text. ...

so i've read plenty of answers on already, saying pull = fetch + merge. i'm not totally convinced. morning instead of doing "git pull" update code everyone's changes, did "git fetch," , ran "git merge" resulted in bunch of errors. actually, "git merge" didn't work on own. i'm on origin/develop branch, did "git merge origin develop" , gave me several errors (which didn't save, unfortunately). so, exact syntax should've used? you should've used git merge @{u} . @{u} shorthand remote tracking branch (e.g., origin/master ). looks might working branch called develop , equivalent: git merge origin/develop . i can't remember if pull ask provide message actual merge--in case cannot fast-forward. so, full command might more akin git merge --no-edit @{u} .

i know there a thread on how number of concurrent users calculated in firebase, doesn't answer question, is: if single user has multiple observers multiple locations in single firebase application, count 1 or several concurrent users? multiple observers multiple location same firebase connection counted 1 concurrent only. every web page shares single connection given firebase, not across iframes or tabs. every node.js, ios or android process share 1 connection per firebase well.

this question has answer here: in order static/instance initializer blocks in java run? 7 answers class prog { static { system.out.println("s1"); } prog() { system.out.println("s2"); } public static void main(string...args) { prog p = new prog(); } } output s1 s2 as per output, seems static initialization block gets executed before default constructor executed. can tell rationale behind ? strictly speaking, static initializers executed, when the class initialized . class loading separate step, happens earlier. class loaded , initialized, timing doesn't matter of time. is possible load class without initializing (for example using the three-argument class.forname() variant ). no matter way approach it: class always initialized @ time create instance of it, static block have been run @ time.

do know how can errors enterprise library 5 logging block? as know, logging's philosophy non disrupting, if there error in configuration example, not error thrown. but in our application, logging critical, need have application out of order, running without logs. so need configure so, throw error if there any. i've found events here: enterprise library logging application block options so should able listen event, , throw our own error @ least, not able reference logging instrumentation, because, cannot see getinstrumentationeventprovider() method in following code. logginginstrumentationprovider instrumentation = logger.writer.getinstrumentationeventprovider() logginginstrumentationprovider; instrumentation.failureloggingerror += (s, z) => { throw z.exception; }; thank help. i think logginginstrumentationprovider definition changed between version 4 , 5 remove events posted approach won't work enterprise library 5. there few ways change beh...
