i'm working on file browser (a ligth file manager if prefer) based on php , javascript. i'm building treeview folders : <ul id="treeview"> <li><a href="#">folder 1</a></li> <li><a href="#">folder 2</a> <ul> <li><a href="#">folder 2.1</a></li> <li><a href="#">folder 2.2</a></li> </ul> </li> <li><a href="#">folder 3</a></li> </ul> each link represent folder. want here loading content of folder after cliking on it. i have php code : public function getcontent($path) { //fetch content of $path directory } i have js code handle events : $('#treeview a').live('click',function(e){ e.preventdefault(); var folder = //here : path loadcontentinpanel(folder); }); but don't know h...

i have multi website, multi stored magento shop, , have need make products available in 1 store_view, not available in other, both store_views part of same store , website. all products configurable simple products attached them. way think of solving registering new product attribute through control each product goes. works great catalog , lists of products, have huge problems single product view , choosing configurable product options. i can't seem find in magento core option generated, override , strict options each store view. basically, need know this generated. last resort managing through ajax, there lot of ajax code , calls in page confusing. any or tip appreciated. i pretty sure way above not working because attribute enable/disable product has impact @ website level , not store or store view! if tomakun says product disabled @ whole website , not store view choose first! i have same problem want assign different products 1 website different stores...

i'm asking questions out of curiostity, since quick , dirty implementation seems enough. i'm curious better implementation be. i have graph of real world data. there no duplicate x values , x value increments @ consistant rate across graph, y data based off of real world output. want find nearest point on graph arbitrary given point p programmatically. i'm trying find efficient (ie fast) algorithm doing this. don't need the exact closest point, can settle point 'nearly' closest point. the obvious lazy solution increment through every single point in graph, calculate distance, , find minimum of distance. theoretically slow large graphs; slow want. since need approximate closest point imagine ideal fastest equation involve generating best fit line , using line calculate point should in real time; sounds potential mathematical headache i'm not take on. my solution hack works because assume point p isn't arbitrary, namely assume p close gra...

i working on site have 2 levels url reaches my objective have clean url's this... http://domain.com/username/dosomething my ugly url's this... http://domain.com/index.php?page=username&command=dosomething my attempt this rewriteengine on rewriterule ^([a-za-z0-9]+)$ index.php?page=$1&command=$2 rewriterule ^([a-za-z0-9]+)/$1/$2 index.php?page=$1&command=$2 you're not using backreferences correctly in first part. backreferences parenthesised expressions filled $1, $2 et al. in second part of rule. e.g.: rewriterule ^([^/]+)/([^/]+)$ /index.php?page=$1&command=$2 these parenthesized expressions match 1 or more non-/ characters , fill them $1 , $2 respectively.

is there way nest translation lookups? this: en: uh_oh: 'uh oh!' error1: :'uh_oh' + ' there big error!' error2: :'uh_oh' + ' there big error!' i18n.t('error1') #=> 'uh oh! there big error!' i18n.t('error2') #=> 'uh oh! there big error!' i've tried bunch of variations of this, , tried using ruby translation file instead of yaml. note does work: en: uh_oh: 'uh oh!' error1: :'uh_oh' i18n.t('error1') #=> 'uh oh!' but if add additional text error1 , uh_oh doesn't translated. basically want avoid having pass in common terms, this: en: uh_oh: 'uh oh!' error1: '%{uh_oh} there big error!' i18n.t('error1', {uh_oh: i18n.t('uh_oh')}) for common terms uh_oh , interpolation same every call error1 (and other key uses uh_oh ), doesn't make sense have pass in string interpolated. it'd easier following...

my question if there easy way compress xml file. read exi, gzip , similar, didn't understand how it, or if question possible. what trying achieve reduce size of xml file use simplexml. possible , if is, have impact on speed/performance/memory ? also, large xml file considered large based on size or number of elements? are there tips should follow "better" xml? the best way can think remove unnecessary data possible. i.e. don't make formatted human readability. include many unnecessary spaces/tabs/newlines. use self closing tags whenever possible , reduce content down bare minimum still meets xml specs. i'm sure there compressors out there this. kind of "compression" not require decompression before parsing, in turn may not save space.

we've been using subversion , considering moving git. git illiterate. used git svn clone copy svn history git , git folder 3.1g. followed advice several blogs shrink , ran: git repack -a d -f --window=100 processed 494,755 objects when @ disk size using 3.7g. thought shrink made larger. tried running again git repack -a d -f --window=250 --depth=250 no changes size. git prune command didn't appear anything. took several days clone this, rather not start over. is there way go smaller size, or ideas has on why repack made bigger? git-svn way if have copy repo svn git, honestly, better work natively in git. said, i've used before , this best guide found on matter. really, may want play around revision history importing using -r option. did an: rm -r `find -type d -name .svn` to remove .svn folders. don't plan on commiting git svn, me, if plan use git locally , commit svn repo, you'll have little more research on best way that. also git-gc...

i encountered stringbuilder first time , surprised since java has powerful string class allows appending. why second string class? where can learn more stringbuilder ? string not allow appending. each method invoke on string creates new object , returns it. because string immutable - cannot change internal state. on other hand stringbuilder mutable. when call append(..) alters internal char array, rather creating new string object. thus more efficient have: stringbuilder sb = new stringbuilder(); (int = 0; < 500; ++) { sb.append(i); } rather str += i , create 500 new string objects. note in example use loop. helios notes in comments, compiler automatically translates expressions string d = + b + c like string d = new stringbuilder(a).append(b).append(c).tostring(); note there stringbuffer in addition stringbuilder . difference former has synchronized methods. if use local variable, use stringbuilder . if happens it's possible accessed...

the to_xml activerecord include xml declaration follows. <?xml version="1.0" encoding="utf-8"?> how change version 1.1 , change encoding? we can use to_xml(:skip_instruct => true) hide declaration altogether. if using restfull routes visiting some_url.xml give results have described. if way serving xml can define own xml builder template. work in same way view works here example your controller action def show @obj = someclass.find(params[:id]) respond_to |format| format.html # show.html.erb format.xml { render :layout => false } end end then in views folder place show.html.erb create show.xml.builder file contents looking this xml.someclass xml.id(@obj.id) xml.name(@obj.name) end in template can add <?xml version="1.1" encoding="utf-8"?> or whatever xml declarations wish add update don't need serving views, restfull route, controller , action has respond_to...

i trying understand why dijkstra's algorithm not work negative weights. reading example on shortest paths , trying figure out following scenario: 2 a-------b \ / 3 \ / -2 \ / c from website: assuming edges directed left right, if start a, dijkstra's algorithm choose edge (a,x) minimizing d(a,a)+length(edge), namely (a,b). sets d(a,b)=2 , chooses edge (y,c) minimizing d(a,y)+d(y,c); choice (a,c) , sets d(a,c)=3. never finds shortest path b, via c, total length 1. i can not understand why using following implementation of dijkstra, d[b] not updated 1 (when algorithm reaches vertex c, run relax on b, see d[b] equals 2 , , therefore update value 1 ). dijkstra(g, w, s) { initialize-single-source(g, s) s ← Ø q ← v[g]//priority queue d[v] while q ≠ Ø u ← extract-min(q) s ← s u {u} each vertex v in adj[u] relax(u, v) } initialize-single-source(g, s) { each vertex v  v(g) d[v] ← ∞ π[v...
