i'm trying reverse situation of stickyfooter: footer should visible (it overlap content), should stick page content when browser height exceeds content (content fixed height). basically, want behave position:fixed when browser height smaller content. i have tried through css way stickyfooter (using max-height instead of min-height), but... my problem: when browser smaller content, footer sticks bottom initially, doesn't keep sticking bottom scroll. as shown here i'm guessing there javascript involved keep stuck bottom, haven't found script (and don't know how write 1 myself...) any help, suggestions, links appreciated! thanks. html, body { height: 100%; font-family: helvetica, arial; font-size: 8pt; } #wrapper { margin: 0 auto; width: 800px; position:relative; height:100%; max-height: 516px; } #content { width:800px; height:400px; position: absolute; background: #999; border: 4px solid #000; } #footer {

i'm considering ways develop site, planning 100-10.000 visitors daily. (fingers crossed). i used prado framework "backend" (admin access), i'm not sure how prado work on visitors frontent. have godaddy hosting , not sure if things work fast enough not lower google rating result of slow site loading. ( if guys think differently, please feel free so ). however, if i'm not going use prado (and i'm lazy learn framework project alone , don't have time right now), i'm having problem sef urls , page caching. i searched around tutorials on subject, noticed of them old. so, guys propose up-to-date tutorials, or verify old tutorials tutorials :) thx if lazy learn different framework how can learn use "sef urls , page caching" without being able integrate them properly? also shouldn't worried google ranking slow-loading website, should worried how slow-loading website impact user experience (which result in drop of traffic).

what difference between putting $db::single=1 , $db::single=2 in code? both seem have identical effect of halting execution @ statement following assignment when 'c' on perl debugger command line. perldebug says value of 1 equivalent having pressed 's' next statement, , 2 same 'n', difference make how got statement? from perldebug : if set $db::single 2 , it's equivalent having typed n command (which executes on subroutine calls), whereas value of 1 means s command (which enters subroutine calls). that know already. from user point of view, i'm pretty sure there no difference. base on examination of actual db.pm source code . let's follow logically. may want refer source code. i've simplified of code remove unnecessary detail should able idea descriptions. when executing code in debugger, there (at least) 2 important variables, running , single . combination of these decides whether code run: running single

i'm trying speed benchmark (3 tier web architecture), , have general questions related memcache(d) , varnish. what difference? seems me varnish behind web server, caching web pages , doesn't require change in code, configuration. on other side, memcached general purpose caching system , used cache result database , require change in get method (first cache lookup). can use both? varnish in front web server , memcached database caching? what better option? (scenario 1 - write, scenario 2 - read, scenario 3 - read , write similar) varnish in front of webserver; works reverse http proxy caches. you can use both. mostly write -- varnish need have affected pages purged. result in overhead , little benefit modified pages. mostly read -- varnish cover of it. similar read & write -- varnish serve lot of pages you, memcache provide info pages have mixture of known , new data allowing generate pages faster. an example apply stackoverflow.com: addin

what best practice integrate azure acs local custom authentication in asp.net mvc application running on azure? requirement web application must have custom authentication , must support main identity provides. i think best approach use azure acs (to nicely support main identity provides) , since acs in based on wif (identity foundation) nicely fit local sts. what recommendations approach? have better suggestions? maybe have examples how integrate acs local sts? do thinking wrong , entities (acs , local sts) separated? , not have aware of each other? make sense me. i new azure acs in wif. the short answer yes, possible. "local sts" part 1 might or might not necessary. if wanted keep own authentication, don;t need own sts so. start simplest thing possible: mvc app relying on sts (e.g. first local one, acs, maybe both). there're many examples here .

i'm spooling out delimited text files sql*plus, every column printed full size per definition, rather data in row. for instance, column defined 10 characters, row value of "test", printing out "test " instead of "test". can confirm selecting column along value of length function. prints "test |4". it kind of defeats purpose of delimiter if forces me fixed-width. there set option fix this, or other way make print actual column data. i don't want add trim every column, because if value stored spaces want able keep them. thanks i have seen many sql*plus script, create text files this: select || ';' || b || ';' || c || ';' || d t ... it's strong indication me can't switch variable length output set command. instead of ';' can of course use other delimiter. , it's query escape characters confused delimiter or line feed.

i know best practice including javascript having code in separate .js file , allowing browsers cache file. but when begin use many jquery plugins have own .js , , our functions depend on them, wouldn't better load dynamically js function , required .js current page? wouldn't faster, in page, if need 1 function load dynamically embedding in html script tag instead of loading whole js js plugins? in other words, aren't there cases in there better practices keeping our whole javascript code in separate .js ? it seem @ first glance idea, in fact make matters worse. example, if 1 page needs plugins 1, 2 , 3, file build server side plugins in it. now, browser goes page needs plugins 2 , 4. cause file built, new file different first one, contain code plugin 2 same code ends getting downloaded twice, bypassing version browser has. you best off leaving caching browser, rather trying second-guess it. however, there options improve things. top of list us

in studying on html5's new section tag, i'm wondering handling of h1, h2, h3, h4, h5, , h6 tags... the html5 specification says "[h1, h2, etc.] elements represent headings their sections " ( http://www.w3.org/tr/html5/sections.html#the-h1-h2-h3-h4-h5-and-h6-elements ). further in spec's "4.4.11 headings , sections" section, there 3 examples of structuring document apples. if follow first specification, states heading elements "should represent headings sections," seems third apple example most correct structure (i.e., using h1 tags heading in each section , subsection). using logic seems h2, h3, h4, h5, , h6 tags used rarely, if @ all. this i'm wondering: should h2, h3, h4, h5, or h6 tags used if, in reality, marking subsections? not make more sense use section tags separate sections, each own header, rather relying on h2, h3, etc. start implicit sections? (the "headers , sections" section talks sections implied using h

say have arbitrary number of collections, each containing objects of same type (for example, list<int> foo , list<int> bar ). if these collections in collection (e.g., of type list<list<int>> , use selectmany combine them 1 collection. however, if these collections not in same collection, it's impression i'd have write method this: public static ienumerable<t> combine<t>(params icollection<t>[] tocombine) { return tocombine.selectmany(x => x); } which i'd call this: var combined = combine(foo, bar); is there clean, elegant way combine (any number of) collections without having write utility method combine above? seems simple enough there should way in linq, perhaps not. i think might looking linq's .concat() ? var combined = foo.concat(bar).concat(foobar).concat(...); alternatively, .union() remove duplicate elements.

i looked upon years old code uses jtestcase separating data test case(jtestcase helps manage data in xml files). jtestcase integrated junit test cases code. jar available jtestcase 2006 version guess there no new release same. makes me think jtestcase old thing use otherwise have provided new version. please tell me if there new technology in place of jtestcase , if not negatives of jtestcase(like 1 can performance considering fact allows use of xml files in trade off better organization of complex data). i couldn't find maven artifact jtestcase. please let me know if available on site. which site dependable source find maven artifact. see https://repository.sonatype.org/index.html#welcome same purpose. that seems lot of effort go write unit test. think negative of using jtestcase doubling amount of code have write. wouldn't use framework unless see significant benefit putting test data xml. think doing tests make harder maintain in cases!
