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.

my array: $numbers = array(1, 3, 5); simply, need change numbers ? question mark , separated , comma. // output (array has 3 items): $string = '?, ?, ?'; you can use combination of str_repeat , count . use rtrim clean trailing comma: $numbers = array(1, 3, 5); $str = str_repeat('?, ', count($numbers)); $str = rtrim($str, ', '); echo $str; // output: ?, ?, ?

i'm trying use mysql field function in order clause in query. i'm assuming doctrine 2 doesn't support field function out of box - true? if so, how can use it? have turn whole query native query? there doctrine 2 extension adds functionality? jeremy hicks, your extension . didn`t know how connect function doctrine, find answer. $doctrineconfig = $this->em->getconfiguration(); $doctrineconfig->addcustomstringfunction('field', 'doctrineextensions\query\mysql\field'); i need field function order entities select in expression. can use function in select, where, between clause, not in order by . solution: $qb ->select("r, field(r.id, " . implode(", ", $ids) .

i interested in using dapper - can tell supports query , execute. not see dapper includes way of inserting , updating objects. given our project (most projects?) need inserts , updates, best practice doing inserts , updates alongside dapper? preferably not have resort ado.net method of parameter building, etc. the best answer can come @ point use linqtosql inserts , updates. there better answer? we looking @ building few helpers, still deciding on apis , if goes in core or not. see: http://code.google.com/p/dapper-dot-net/issues/detail?id=6 progress. in mean time can following val = "my value"; cnn.execute("insert table(val) values(@val)", new {val}); cnn.execute("update table set val = @val id = @id", new {val, id = 1}); etcetera see blog post: that annoying insert problem update as pointed out in comments, there several extensions available in dapper.contrib project in form of these idbconnection extension methods:

from question started looking: firefox screwing headings sizes h1 h2 h3 here html snippet show issue: <html> <head> </head> <body> <section> <section> <h1>this h1</h1> <h2>this h2</h2> <h3>this h3</h3> <h4>this h4</h4> </section> </section> </body> </html> so save test.html , open in firefox 4 , in chrome, h1 tag shows way smaller in firefox 4. can explain me how fix ? it possible use <h1> tag multiple times in same document part of html5. <h1> tag used title section. apparently, firefox implements nested section indication reduce size of <h1> sub-section, makes sense, while chrome not. more info http://brugbart.com/references/html-section-tag http://brokensyllabus.blogspot.com/2008/02/proper-use-of-h1-tag.html

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

there tons of ways handle forms in general, i'm wondering if has solid solution use of apps, can build out forms , include types of form elements. what i'm using ci's built-in form validation , building out form, this, feel takes long... suggestions? there jquery plugin (called "dform") take json input build form dynamically. have been using while now. please take @ following url: http://neyeon.com/p/jquery.dform/doc/files2/readme-txt.html quick usage: var formdata = { "action" : "index.html", "method" : "get", "elements" : [ { "name" : "textfield", "label" : "label textfield", "type" : "text", "value" : "hello world" }, { "type" : "submit", "value" : "submit" } ] }; $("#myform").buildform(formdata); /

i have java application running on windows mobile device. need able turn bluetooth on , off executing native code this. problem trying out on new device (the htc hd2) , native code doesn't work. reason hd2 device using widcomm bluetooth stack, whereas other device using microsoft stack. i have found way of activating bluetooth on hd2 device using widcomm sdk. native code needs able run on device, somehow need able make decision @ runtime code run based on bluetooth stack present. question 1: how can determine programmatically stack present? question 2: if include header file required widcomm stack , try run on device doesn't use code fails. how can compile dll includes header file if widcomm dll exists? i'm guessing can have dynamically: declare prototypes necessary widcomm functions in own code. use loadlibrary load widcomm dll. if loadlibrary call fails know you're on microsoft stack , can run standard microsoft stack functions. if load

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.
