Compiling Java class targeting 1.7 with classes built with JDK 8 on class path -

i have following scenario: class foo references method in class bar. i'd compile class foo javac targeting java 1.7 providing bar.class binary on class path uses java 8 syntax , compiled jdk 8. in production, jre 1.7 used run application different copy of bar.class on classpath - version of class bar uses java 1.7 syntax , built jdk 7. assuming method signatures bar remain same, there issues compiling , running foo? can compile foo using jdk 7 or must use jdk 8? for straight javac, can use -source/-target let java8 jdk build java7 class files (which means putting different version number in class file). my builds use maven, , while jenkins server building java8, source/target specified 1.7 , run existing java7 jdk. when first dependent project migrated java8, maven pom changed build 1.8 target , forced upgrade.

memory management - Frame Allocation -

i have 2 operating system related questions. first 1 relates frame allocation, more equal allocation specific situation. situation have there 200 free frames in memory , 2 processes trying paged in - p1 has 50 pages, , p2 has 350 pages. question happens p1? give p1 100 frames because having 2 processes , giving them equal number make each 100, or give p1 50 frames , give rest p2? assume later option don't know sure. the answer question highly operating system specific , time specific. in ye olde days of limited physical memory common operating systems swap process in , out of physical memory when there paging. now more common rely on paging. p1 may have 50 pages os may keep 5 of @ time in memory. generally pages loaded when accessed. there has page fault load page. (there exceptions general rule).

bash - is it possible to scan a file in reverse (bottom up) using ack? -

is possible scan file pattern in reverse (bottom up) using ack (the grep alternative)? right using: tac filename | grep -m1 blablabla but friend mentioned ack might able type of thing without use of tac. went through man file , not find mentioning capability (or maybe dumb , missed it). if not possible above, more efficient way of doing type of search? (find first match of pattern starting @ bottom of file) reading file in such reverse line-oriented fashion going inefficient, due how files stored on disk. file linear stream of bytes, accessible offset beginning file. line not distinct object; rather, it's abstraction defined conventional byte (or pair of bytes) know line ending. first line beginning of file first line ending, second line after first line ending second line ending, , on. in order access lines in reverse, still need scan entire file beginning find last line. the command line have can do. i'm not aware of option ack reverse line-iteration ...

Future-proofing a Scala/SBT project -

i trying use scala-graph , scala-swing in same program. can use latest graph-core library (1.9.2) alone latest version of scala (2.11.6). can use scala-swing, when that, sbt gives me scala 2.10.4 rather 2.11.6. when tried use both libraries, got errors -- either compilation or runtime errors, depending on how set build.sbt. tried using older version of graph-core (1.8.0), if understand library's release history [1] correctly, designed scala 2.10. doing works, although causes sbt use scala 2.10.4 instead of 2.11.6. i'm worried because seems fragile arrangement. will keep working? build.sbt file (below) not restrict scalaversion or scala-compiler version; says graph , swing libraries use. i'm afraid changes graph library, or swing library, or scala language itself, break code. [the rest of post describes os, installations, , code; might not need read it.] i using ubuntu 14.04. installed scala , sbt using apt-get. swing appears installed on machine. did not insta...

sql server - GUID PK + INT IDENTITY Clustered Index + Merge Replication + Foreign Keys -

i have database guid pks, , understand performance benefit adding int identity column (e.g. clusterid ) , creating clustered index on it. and joins there performance benefit using clusterid column foreign key. in parent/child situation child table have clustered index on parent clusterid . however in merge replication scenario that's not possible because clusterid column not unique. so i'm wondering how best gain performance benefits in situation. for example: tablea id guid (primary key) clusterid int identity (clustered index)` tableb id guid (primary key) tableaid guid (foreign key tablea) tableaclusterid int (clustered index)` i guess use trigger keep tableaclusterid up-to-date. then query such as select * tableb b b.tableaclusterid = @tableaclusterid would benefit increased performance. is how done? for heavy inserts guid perform better int identity because won't have contention on it. there technics fix it, still ca...
