"|" . $_server['request_time']; this way know when key generated, , if it's been tampered because: function check($key) { list($hash, $timestamp) = explode("|", $key, 2); if ($hash !== md5($password . $key)) { throw new exception("naughty!"); } if ($timestamp < $_server['request_time'] < 60*60) { thr...

i have implemented version of code below on development system. function validatetextbox(textboxid) {   var textbox = document.getelementbyid(textboxid);   if(document.activeelement.id != textbox.id) {      do validation   } } the html similar to: <input type="text" id="validateme" onchange="validatetextbox('validateme');"/> the idea validation takes place after user has completed editing textbox , that, unlike onblur event, validation fires when value of textbox has changed. it seems work i'm leery of using without review , feedback. i haven't seen similar code examples. please give me thoughts on implementation , alternate ideas may have. thanks this fine solution. keep in mind onchange event typically fire when focus changes (ie. onblur) if want validation while user typing can use onkeydown/onkeyup/onkeypress that's quite ways harder. additionally can use this don't ...

finding nth term in fibonacci series f(n) = f(n-1) + f(n-2) can solved in o(n) time memoization. a more efficient way find nth power of matrix [ [1,1] , [1,0] ] using divide , conquer solve fibonacci in log n time. is there similar approach can followed f(n) = f(n-1) + f(n-x) + f(n-x+1) [ x constant ]. just storing previous x elements, can solved in o(n) time. is there better way solve recursion. as suspecting, work similar. use n-th power of x * x matrix |1 0 0 0 .... 1 1| |1 | 1 | 1 | 1 | 1 ................... ................... | ... 1 0| this easy understand if multiply matrix vector f(n-1), f(n-2), ... , f(n-x+1), f(n-x) which results in f(n), f(n-1), ... , f(n-x+1) matrix exponentiation can done in o(log(n)) time (when x considered constant). for fibonacci recurrence, there closed formula solution, see here http://en.wikipedia.org/wiki/fibonacci_number , binet's or moivre's formula.

i've made jquery scroll bar ( http://www.liime.net/projects/liimebar/demo_2.html ) i've realized doesn't work when mouse in iframe both mousemove events bound document when clicks scroll button , mousewheel event (mousewheel plugin) bound document. have ideas on how deal this? what use old opacity 0 trick. basically, wrap iframe inside container div, wrap div (or readonly textarea) opacity 0, wraps iframe. this used cause issues on ie, , overall prevent user interact iframe content, , i'm quite curious if better has come since. check this fiddle

maybe stupid question, i'd raise here since it's not clear me: git commit file content snapshot relative svn commit delta storage systems, mean git needs more disk space svn ? thinks shall delta in reasonable. logically, git stores every file (actually, every object) in repository , identifies them sha1. can @ yourself, objects in directories in .git/objects identified first 2 characters of sha1. but git supports storing (and transferring) objects in called packfile. file contains objects compressed using zlib. can contain delta-compressed objects reference object in same packfile (it doesn't have previous version of same file). objects saved normal files compressed packfile when call git gc . happens automatically during of git operations produce “loose objects”. because of this, git working directory smaller svn working directory. great, considering git working dir contains history of repo. (svn working dir twice size of files in it. that's becaus...

say have list, , have object. how find index of object in list? you can use findindex find index of object in generic list: flexible method index of object. dim list new list(of object) const myapple = "apple111" = 0 1000 list.add("apple" & i) next dim indexofmyapple = list.findindex(function(apple) (myapple.equals(apple))) but indexof method simplier , more straightforward if want find object in list defaultequalitycomparer : dim indexofmyapple = list.indexof(myapple) you can use indexof if don't know type is, .net use equals determine if 2 objects equal(should overridden not compare references).

as title suggests, have difficulty explaining this. :p i have 3 tables in phpmyadmin setup. within 1 of tables, contains 2 foreign keys. e.g foo_id , bar_id. these have been indexed , displaying fields names. is possible constrain can selected in bar_id after first selecting foo_id? if x=1 print = 6-10 else print 1-10 thanks in advance. i don't think can constraint, if wanted achieve trigger. however kind of validation logic in app layer, unless people going using database directly.

how come works render :json no template, not render :csv? in datapoints_controller's index method: respond_to |format| format.json { render :json => @goal.datapoints.all } format.csv { render :csv => @goal.datapoints.all } end pointing browser /datapoints.json renders collection json string on screen. pointing /datapoints.csv gives error: template missing: {:locale=>[:en, :en], :formats=>[:csv], :handlers=>[:rhtml, :rxml, :erb, :builder, :rjs]} an instance of datapoint responds to_csv, if manually map csv format , render text gives template missing error, so, e.g. tried this: format.csv { render @goal.datapoints.map{|d| d.to_csv }.join "\n" } rails comes renderers bunch of formats, including json, not csv. here's specified in rails source (look towards bottom series of add calls). it's pretty easy create own though. put initialiser (this pretty copied xml renderer above link, xml replac...

i trying create program has multiple layers of controls drawing on top of each other. way i'm doing have windows.forms.panel container panels doing actual drawing (this way can layer them). for panels doing drawing have abstract class inherits windows.forms.panel (call abstractpanel) have set docking style "fill". overrides onpaint function in calls abstract function override in children. the problem have when add control inherits abstractpanel container isn't showing (the onpaint function isn't being called). any suggestions? am thinking java perspective , need make abstractpanel not abstract? i've had similar issue visual studio winforms designer: if form inherits abstract class, doesn't shown in designer @ all. don't know why, reason windows forms doesn't "like" abstract classes. try removing abstract keyword, won't change functionality if do.
