is there way purge folder , keep dotfiles? i'd purge /root. something like: file { '/root': ensure => present, owner => 'root', group => 'root', mode => 0550, purge => true, recurse => true, } file { '/root/.*': ensure => present, owner => 'root', group => 'root', } either go ignore param h2ooooooo correctly stated. you may find cleaner not recurse , use tidy type , matches parameter instead. tidy { "/root": recurse => 1, matches => '[a-za-z0-9_]*' }

can join 1 system component of second subsystem dependency ? my intence show in system(system 2) module / component called subsystem 1 , external system uses subsystem. correct? interfaces aren't defined now, can show dependency. let me interpret diagram , answer should come naturally. :) "system 1" depends on "subsystem 1" in way. "system 1" not know "system 2", contains "subsystem 1". means "system 1" somehow gets direct access "subsystem 1", no contact "system 2". is correct? that's answer question. :)

in huffman coding algorithm, there's lemma says: the binary tree corresponding optimal binary prefix code full but can't figure out why. how can prove lemma? from wikipedia , a full binary tree (sometimes 2-tree or strictly binary tree) tree in every node other leaves has 2 children. the way in tree huffman code produced produce full binary tree. because @ each step of algorithm, remove 2 nodes of highest priority (lowest probability) queue , create new internal node these 2 nodes children.

we've been using jmap ~2 years measure heap size on large, multi-server app, running under java 6. take measurement every minute. each measurement took (elapsed time) less 1 second. we're testing same app under java 7. , jmap takes 10 seconds, 20 seconds, longer, , seems slow down (or perhaps stop!) jvm during time. the difference see in jmap output (between java 6 , java 7) additional information how many strings interned. (and seems that's part slower.) does know going on, or changed in jmap or java 7 might cause this? we're testing using "jstat -gc" same information, , far seems faster, , not appear cause app slowdowns saw jmap. there other suggestions how measure heap size, quickly? any thoughts welcome, in advance. i quite oracle mission control monitoring heap size. has many more options, works charm monitor heap size.
