it's been few years since i've used regex, if remember correctly, following should work: string test = "axaxa"; pattern p = pattern.compile("([a-c])x\1x\1"); matcher m = p.matcher(test); m matches nothing on run. super simplified version of i'm doing in code. example taken java tutorial on regex! tried rewrite html matching code way when didn't work, went researching, thinking did wrong... according internet, haven't. so. have clue why doesn't work? extra info, test.matches(the_pattern) returns false . seems group backtracking messing up. try using \\1 in pace of \1 . \ escape character in java string. send \1 regex engine, need escape \ \\1 .

i have asp.net 3.5 web project. there lots of images on images folder. apprx. 1.5gb size. everytime want publish project, takes 35minutes. dont want publish folders. want publish pages. im using shared web hosting. how can solve problem? thanks. remove images folder project. publishing website publish folders part of project, removing folder project ensure not published. this add burden maintaining site , ensuring have images on development environment. you can still have in source control if wish.

my couchdb (production) server shut down, without wanting to. while inspecting logs noticed erlang/couchdb (one or other) sends heart beat, , heart beat monitored. when time-out occurs, server brutally killed ( couchdb -k ). unwanted behaviour, on production server. i've come across this issue , states same , indicates occurs during heavy server loads, noticed also. i'm looking solution keep server running, need know more behaviour. unfortunately both the couchdb wiki , the guide don't give information (only parameter in changes api). can provide more info this? the couchdb -k should kill background process , couch should restarted. default restart feature disabled. enable should use -r parameter value greater 0. can in bin/couchdb script - change respawn_timeout 0 e.g. 5.

i read metaphor objects use message passing while passing message object. possible capture/log such messages! learning purposes, thought necessary handly tool provenance system! you might want @ aop (aspect oriented programming) . in essence allows capture object events such method invocation , apply logic them. in case it'd print out traces. have @ a lightweight approach aspect-oriented programming in python , should need.

1) want have client application adds reference wcf service 2) client application should able send credentials wcf service 3) based on credentials permissions, wcf service should return appropriate interface (service contract) client 4) client consumes it. e.g. suppose hav class @ server, defines entity 'asset' , have methods related possible operations on it class asset { add() { ..... } edit() { ...... } flag() { ...... } deploy() { ........ } } now have client application wants perform actions on 'asset'. don't want give entire class dll client. instead want give interface. client can consume , call appropriate actions on it. now problem when client app adds reference wcf service. how can appropriate interface asset class returned client based on ws* or authentication credentials. .net 4.0 provides easy way create , return service contract dynamically? e.g. //following pseudo code if(current.user.role == 'admin') {

i'v hash {1=>true, 7=>false, 6=>true, 4=>false} or array [1, true], [7, false], [6, true], [4, false]] or [true, false, true, false] . how can find number of true s in array? in order count elements, have iterate on collection. since iterating on hash yields two-element array s, first 2 same: { 1 => true, 7 => false, 6 => true, 4 => false }.count(&:last) [[1, true], [7, false], [6, true], [4, false]].count(&:last) for simple array case, this: [true, false, true, false].count(true) this array of course same hash#values hash above, use same method on that: { 1 => true, 7 => false, 6 => true, 4 => false }.values.count(true) if don't know 1 of 3 get, use this: { 1 => true, 7 => false, 6 => true, 4 => false }.flatten.count(true) [[1, true], [7, false], [6, true], [4, false]].flatten.count(true) [true, false, true, false].flatten.count(true)

i'm building wordpress theme, , work without having separately download plugins uses (e.g. internalization, contact form , lightbox). is possible place plugin files inside wordpress theme (or there way of solving this)? e.g: wp-content/themes/my-wordpress-theme/plugins when theme comes packaged own plugins, end user instructed install in /wpcontent opposed normal /wp-content/themes directory plugins , theme files installed in appropriate places. want separation between form , function. the theme should include hooks plugins, , administrator has activate them after installation. packaging theme trying do; broadening definition of theme bit include plugin directory. if determined have plugin directory subdirectory of theme, i'm not sure if or how that's doable, bad practice because doesn't maintain separation between form , function.

i starting work boost graph library. need best-first search, implement using astar_search having 0 costs. (please correct me if i'm wrong.) however, wonder if there possibility of doing this? if costs not considered, algorithm should more efficient. edit: sorry unclear description. implementing potential field search, don't have costs/weights associated edges rather need steepest-descent-search (which can overcome local minima). thanks hints! you use a* tackle this; you'd need h(x) 0 though, not g(x) . a* rates nodes based on f defined f(n) = g(n) + h(n). totalcost = pathcost + heuristic. g(n) = path cost, distance initial current state h(n) = heuristic, estimation of cost current state end state. from wikipedia : dijkstra's algorithm, example of best-first search algorithm, can viewed special case of a* h(x) = 0 x.

so, common interview question. there's topic up, have read, it's dead, , no answer ever accepted. on top of that, interests lie in more constrained form of question, couple practical applications. given 2 dimensional array such that: elements unique. elements sorted along x-axis , y-axis. neither sort predominates, neither sort secondary sorting parameter. as result, diagonal sorted. all of sorts can thought of moving in same direction. ascending, or descending. technically, think long have >/=/< comparator, total ordering should work. elements numeric types, single-cycle comparator. thus, memory operations dominating factor in big-o analysis. how find element? worst case analysis matters. solutions aware of: variety of approaches are: o(nlog(n)), approach each row separately. o(nlog(n)) strong best , average performance. one o(n+m): start in non-extreme corner, assume bottom right. let target j. cur pos m. if m greater j, move left. if

using awesome_nested_set rails 3, i've created hierarchical categories system. display category selector in view, i've used following code: <%= form.select :parent_id, options_for_select(nested_set_options(category, @category) {|i| "#{'-' * i.level} #{i.name}" }.unshift(["no parent", nil]), @category.parent_id) %> i'm attempting order categories in alphabetical order, on level level basis. if change nested_set_options(category, @category) nested_set_options(category.order("name"), @category) reorder whole categories list name; want reorder children of each node alphabetically name. for example, want resulting select menu ordered this: animal - bird -- chicken -- hawk - fish -- cod -- goldfish -- trout - mammal -- cat -- primate --- chimpanzee --- human -- zebra plant - tree although unfamiliar awesome_nested_set, can call order twice in rails 3. category.order(:level).order(:name) this should order categ

i heard bit should keep code in controllers less possible. put code? this depend on code talking about. example if talking validation, should go model, if talking data access should go repository or model (personally prefer repository), if talking business logic should go service, that's left controller call thing , pass result view. i recommend watching this video presentation how put controllers on diet jimmy bogard.
