in parallel program i'm writing, defined lot of multidimensional allocatable arrays (actually 1d, 2d or 3d) allocated negative lower bounds during execution. reason why did each process handles, in 2d example, 14 14 a matrix , shares overlap of 2 layers four neighboring processes, matrix allocated bounds (-1:12,-1:12) , "internal" part of matrix corresponds indices 1 10 . (italic represent choice/input dependency). the problem in doing didn't realize have been impossible rely on this fortran2003 feature , making impossible call mysub(a(:,i),...) in caller unit , refer dummy counterpart of a in subroutine using actual bounds ( -1 , 12 ), since a(:,i) expression, , not variable. the problem solved if pass whole array a subroutine, explained in previous linked answer , force me write "bigger" , less universal subroutine, which, on contrary, meant act on one-dimensional subarrays. is possible pass subarray of allocatable array (e.g. a(:,1)

i need make websocket close gracefully. firstly send messages waiting in buffer close. channel.flush(); channel.close(); seems not right, because dont have completion handler flush method close after done. is there way this. netty used: 4.1.0.beta3 the trick can use writeandflush empty buffer, attach listener call. unpooled.empty_buffer can make pretty easy. channel.writeandflush(unpooled.empty_buffer).addlistener(... channel.close(); )}; if want close channel after flush can use channelfuturelistener.close simplify code. channel.writeandflush(unpooled.empty_buffer).addlistener(channelfuturelistener.close); if enough, may want write static helper method like netty examples do .

there plenty of examples of both on web. php manual says "the include() statement [...]", seems contradictory - if it's statement shouldn't not have parenthesis? both of these work: include('somefile.php'); include 'somefile.php; so should or else care? quoting manual (my emphasis) because include() special language construct , parentheses not needed around argument. these called "special forms", , include such things echo , return statements. note while none of these functions, can still speak of expressions , statements, difference being former have value while latter don't. since include , include_once , require , require_once return value ( true if include successful), can used in expressions. reasoning, "include statement" incorrect, though include s used statements.

i going through guava code base , in preconditions source there explanation quoted below: all recent hotspots (as of 2009) really have natural code if (guardexpression) { throw new badexception(messageexpression); } refactored messageexpression moved separate string-returning method. if (guardexpression) { throw new badexception(badmsg(...)); } the alternative natural refactorings void or exception-returning methods slower. big deal - we're talking factors of 2-8 in microbenchmarks, not 10-20%. (this hotspot optimizer bug, should fixed, that's separate, big project). the coding pattern above heavily used in java.util, e.g. in arraylist. there rangecheckmicrobenchmark in jdk used test this. but methods in class want throw different exceptions, depending on args, appears pattern not directly applicable. can use ridiculous, devio

my question theoretical. suppose have class class a{ private: int * a; int b; private: a(){ = new int[100]; b = 100; } ~a(){ delete [] a; } } as far know if create object of type dynamically ( a * = new a() ) memory object allocate in heap , if use ( a a ) created on stack (a a) . in case when object created on stack memory variable a allocated on heap , in case when allocated object on heap memory object b allocated on stack. first question me sure: right? and second question more efficient store members of class in heap memory or stack memory eg? class a{ private: int * a; int * b; private: a(){ = new int[100]; b = new int(100); } ~a(){ delete [] a; delete b; } } when said efficient mean data class member storing near each other in memory in heap or stack (actually i'm not sure correct storing near each other). first

recently updated vps 1gb 4gb memory. i'd hoped queries (mysql/innodb) running faster more memory, unfortunately that's not case. mysql automatically takes more memory when server has more memory or have change settings in my.cnf? , if so, changes should make? mysql not automatically take benefit of more memory installed. in case (given using innodb ) can @ least these improve performance of mysql: increase innodb_buffer_pool_size (default value option 128mb ). defines how memory dedicated mysql innodb cache data tables , idexes. means if can allocate more memory mysql cache more of data resulting in faster queries (because mysql in memory instead of doing i/o operations data lookup). of course should allocate reasonable amount of memory (not whole 4g :)) may not more 2g . should try , test on server more accurate result. (read more info, before change option https://dev.mysql.com/doc/refman/5.7/en/innodb-buffer-pool-resize.html ) increase innodb_buffer_pool

i have looked @ similar question , answers didn't work , may dated. think there used thing called rjs but, trying remove 1 partial , replace another. $("#me") .replacewith( '<%= escape_javascript render(partial: "photospread") %>') what happens sent browser text , displays <%= escape_javascript render(partial: "photospread") %> replace <% <%= $("#me").replacewith('<%= escape_javascript render("photospread") %>') <% evaluate ruby code inside it whereas <%= evaluate , print code inside <%= %>

i have problem, think can easly solved, can't it. i have class , b , class stored in postgres db: public class a() { private b b; ... } public class b() { private string firstname; private string lastname; private string personid; private string username; } in database, object of class b stored string username in entity. have object of class db in app, have read record , create object of class b. want create query jooq, jooq not know how convert string username instance of class b. how tell jooq how should map database object object of class a. a class equivalent person , b class equivalent executor. my query return jooq.select() .from(person) .where(person.id.eq(id)) .fetchoneinto(person.class); this exception thrown query caused by: org.jooq.exception.datatypeexception: cannot convert superadmin (class java.lang.string) class fi.ssm.oksa.domain.person.executor @ org.jooq.tools.convert$convertall.fail(convert.java:1118) ~[jo

i implementing logger in go. thinking of using logrus this. wanted understand limitations of built in log package. i know if want write logs file or implement rolling file logs etc need add feature manually. there other limitations have choose external log package? logging file using builtin log package not issue, can use log.setoutput() or logger.setoutput() set destination io.writer other default os.stderr , example file *os.file . what's missing , whished leveled logging (e.g. info , warn , debug , error etc.). reasoning, read blog post dave cheney: let's talk logging . you can't enforce specific log.logger used designated packages unless packages "willing" cooperate (e.g. provide setlogger() function). rolling log files missing feature. on other hand, it's easy "extend" standard logger log mongodb example, details see go: create io.writer inteface logging mongodb database . using mongodb can use capped collection im

instead of entire row being deleted, cell(i,8) gets deleted. code is, each cell until last row, if cell starts im, highlight it, , if corresponding cell less 4, delete row. thanks for = 1 lastrow if left(cells(i, 1), 2) = "im" cells(i, 1).interior.color = rgb(140, 220, 100) if cells(i, 8).value <= 4 rows(i).entirerow.delete end if end if next open immediate window. write these two: rows(5).entirerow.delete rows(5).delete see row 5 gets deleted. code wrong, running else.
