i'm looking @ bbc site, , putting following similar overall pattern, , determining how mark appropriately stumping me somewhat. the bbc consists of several considered sites in own right: http://www.bbc.co.uk http://www.bbc.co.uk/comedy/ http://www.bbc.co.uk/news/ www.bbc.co.uk/[a-lot-more-stuff] (these subdomains instead - indeed, case me - urls not important) each of these self-contained, own content, menu , , feel. of them tied use of (slightly variable mostly) static header bar. contains header "bbc" along links of various sub-sites. so question is, how should marked up. see several different options: the main bbc header site's main <header> , <nav> . sort of correct, because ends de-emphasising importance of sub-site's actual content. when boils down (to use examples above), title "comedy" , associated menu main content of page, not bbc bar. make sub-sites' header , navigation ones marked within <header> ...

has run across java/java ee framework causes problems if used scala? don't know of specific one, pre-java 5 framework uses raw types may cause trouble @ point in scala, if have raw type in hierarchy of class must implement. here few questions related issue: implementing methods having raw types in scala why scala complain illegal inheritance when there raw types in class hierarchy? scala class cant override compare method java interface extends java.util.comparator

here snippet of code ability class if user.admin? can :manage, :all can :destroy, :all if != current_user i sure can figure out trying here. realize destroy included in manage , repeating myself there. suggestions? edit yjerem's answer correct 1 , changed fit code. looks like. if user.admin? can :manage, :all cannot :destroy, user, :id => user.id as yjerem said, in cancan, ability precedence states ability defined lower down trump ones on them admin can manage except defined under using code above. read ability precedence , there's example there you! basically want cannot method: if user.admin? can :manage, :all cannot :destroy, user, :id => current_user.id because cannot rule below more general one, overrides it.

in public class, have private static dictionary. since dictionary static, mean shared across other instance of same object (see example below). public class tax { private static dictionary<string, double> taxbrakets = new dictionary<string, double>(stringcomparer.ordinalignorecase) { { "individual", 0.18 }, { "business", 0.20 }, { "other", 0.22 }, }; public string type { get; set; } public double computetax(string type, double d) { return d * taxbrakets[this.type]; } } is acceptable use dictionary in way (as static variable)? your static variable taxbrakets not associated instance. this.taxbrakets not compile. occurrences of taxbrakets refer same dictionary. in general, it's totally acceptable use static dictionaries. particular use seems little funny though, i'd need see more code suggest changes.

i have application stores relationship information in mysql table (contact_id, other_contact_id, strength, recorded_at). fine if need show contact's relationships or generate list of mutual contacts 2 contacts. but need generate stats like: 'what total number of 2-way connections of strength 3 or better in january 2011' or (assuming each contact part of group) 'which group has number of connections other groups' etc. i found sql generating these stats became unwieldy real fast. so wrote script given date generate graph in memory. run whatever stat wanted against graph. easier understand , in general, more performant -- except generating graph part. my next thought cache graphs call on them whenever needed run new stat (or generate later graph: eg today's graph take yesterday's graph , apply changes happened since yesterday). tried memcached worked great until graphs grew > 1 mb. so i'm thinking using graph database neo4j. only problem ...

i tried search answer, maybe i'm phrasing question wrong, couldn't find it. so, in own linux environment, when exit "vi", content of editing window stays in shell window. cannot scroll see previous commands typed before entering "vi". i've been in environment (as different user) once exit "vi", vi command shows 1 regular command line following earlier commands typed. tried setting behavior, liked, couldn't. can please me? it isn't vi setting per se; in terminfo entry use ( $term ). check on other user has set $term , , compare have set. then, either change term value, or modify terminal entry use. infocmp decompiles terminal entries; tic compiles them. can create own directory hold entry if can't modify system 1 (or while testing modifications): mkdir $home/terminfo export terminfo=$home/terminfo tic -o $terminfo new.terminfo.src etc.
