so have been writing game while , have finished. due fact game meant class , used libraries teacher isn't going bother installing need make single executable run independent of python , games dependencies. ran py2exe , completed when run exe error: traceback (most recent call last): file "main.pyw", line 1, in <module> file "zipextimporter.pyo", line 82, in load_module file "libs\__init__.pyo", line 3, in <module> windowserror: [error 3] system cannot find path specified: 'c:\\users\\matt\\workspace\\cos125\\src\\dist\\includes.zip\\libs/*.*' i have figured out cause of error is. stems auto importer have installed each package. in init .py files packages use following code simple "from libs import *" import files in lib package. make each file loaded if loaded each 1 "from libs.module import *". the code in init file follows: import os, sys path = os.path.dirname(__file__) dirlist = os.listdir(...

i have table of games laid out in grid , want drag square anther square, , invoke function. game squares must have id corresponding game represent (or contain div id). i want drag table cell other table cell , invoke ajax action both id numbers, can swap game bookings. i don't know start , can't find close. yes, have how to, doesn't show me how extract id number each element. you should able need when drop performed. if basic set is: <table><tr><td id="cell_1"></td><td id="cell_2"></td></tr></table> just set cells draggable , droppable in drop event: $('td').draggable().droppable({ drop: function(event, ui) { var dragged_id = ui.draggable.attr('id'); // cell dragged var dropped_id = $(this).attr('id'); // cell dropped $.ajax(...); } });

am missing obvious here? appears inverse function of which missing base r (googling , search on "r inverse which" returns myriad of unrelated links)? well, not can't write one, relieve frustration being missing , r-muscle flexing challenge: how go writing one? what need function like: invwhich<-function(indices, totlength) that returns logical vector of length totlength each element in indices true , rest false . there's bound lot of ways of accomplishing (some of low hanging fruit), argue why solution 'best'. oneliner anyone? if takes account of other parameters of which ( arr.ind ??), that's better... one-liner solution: invwhich <- function(indices, totlength) is.element(seq_len(totlength), indices) invwhich(c(2,5), 10) [1] false true false false true false false false false false

is possible rename 'default' 'production' in tortoisehg? you cannot directly tortoise2.0+ settings , through command-line hg . documented in hgbook : mercurial lets assign persistent name branch. there exists branch named default. before start naming branches yourself, can find traces of default branch if them. to start working named branches , use hg branches command $ hg branch production marked working directory branch production $ hg branch production check if change reflected in tortoisehg

i lost netbeans project folder of project working on @ time. somewhere on server here @ company work at, deployed it. means (hopefully) can still hold of .war file. is possible 'unpack' .war , .java source files working on @ time? thanks in advance! if .java sources aren't in war (and should not be), you'll have take additional step of decompiling them using tool jad. this time set version control system, subversion or git or mercurial, never happens again. habit of using source code management, if you're sole developer working on project.

how select top of list long items @ top of list have property specific value. i need linq statement see there break in sequence , return top 2 items. problem don't know how many items going have correct property value. i have been working through problem linqpad 4. code below copy , past linqpad 4. results, "q", should not contain somedata effectivedate of 4/5/2011 because kind property on hsc2 "kindtwo". i trying find value resent value of "kind" , take top records match value until record doesn't match value. void main() { var hsc1 = new somedata {effectivedate = new datetime(2011,4,5), kind = "kindone"}; var hsc2 = new somedata {effectivedate = new datetime(2011,4,10), kind = "kindtwo"}; var hsc3 = new somedata {effectivedate = new datetime(2011,4,20), kind = "kindone"}; var hsc4 = new somedata {effectivedate = new datetime(2011,4,25), kind = "kindone"}; var = new [] {hsc1,...

this contrived example i'm using understand r better. lets want subset character vector called "test". want return each element value third character last character. doesn't work: test = c( "jane" , "jerry" , "joan" ) substr( test , 3 , length( test ) ) expecting: "ne" , "rry" , "an" is there way without loop? use nchar() . it's vectorized: > test = c( "jane" , "jerry" , "joan" ) > substr( test , 3 , nchar( test ) ) [1] "ne" "rry" "an" given nchar return vector of lengths, , substr likewise vectorized, , expects work vector arguments, 1 potential puzzle why accepts scalar argument of 3 . answer here scalars start , stop arguments recycled match length of input character vector. could, therefore, use 1:2 start argument , alternating complete , complete strings: > substr( test , 1:2 , nchar( test ) ) [1] ...

google chrome 11 supports uploading folders. feature implemented in google docs, , have been unable find api documentation on how use in code. from can see, click upload folder link in google docs, displays "browse folder" dialog (a call shbrowseforfolder looks of it), select folder, , contents of folder uploaded google docs. as feature requires upgrading google chrome latest version, or other browsers running java applet, assume can use feature in own websites? i love have feature in content management system maintain! you should able see demo here: http://html5-demos.appspot.com/static/html5storage/demos/upload_directory/index.html basically works setting attribute "webkitdirectory" on file input element. <input type="file" id="file_input" webkitdirectory="" directory=""> then when user has selected folder, itterates across "e.target.files" object list of files included in selection (...

whats recommended way poll url every 5min (in background) on phone 7 (mango) device ? are periodic agents limited 30min polling ? should looking push notifications ? any pointers/hints appreciated. thanks yop should looking push notification (it's lot more complicated periodic agent...) but periodic agent set 30 mins (and 25sec of code execution think) , there nothing can it. note user can decide deactivate periodic agent in options. but pushing notifications every 5 minutes on phone might not idea anyway... it's gonna drain battery quickly! what trying accomplish?

i have 2 numpy arrays (3-dimensional uint8) converted pil images. i want find if first image contains second image, , if so, find out coordinates of top-left pixel inside first image match is. is there way purely in numpy, in fast enough way, rather using (4! slow) pure python loops? 2d example: a = numpy.array([ [0, 1, 2, 3], [4, 5, 6, 7], [8, 9, 10, 11] ]) b = numpy.array([ [2, 3], [6, 7] ]) how this? position = a.find(b) position (0, 2) . this can done using scipy's correlate2d , using argmax find peak in cross-correlation. here's more complete explanation of math , ideas, , examples. if want stay in pure numpy , not use scipy, or if images large, you'd best using fft based approach cross-correlations. edit: question asked pure numpy solution . if can use opencv, or other image processing tools, it's easier use 1 of these. example of such given piquer below, i'd recommend if can use it.

may noob question i'm starting playing around apache , have not found precise answer yet. i setting web app using url-rewriting massively, show nice urls [mywebsite.com/product/x] instead of [mywebsite.com/app/controllers/product.php?id=x]. however, can still access required page typing url [mywebsite.com/app/controllers/product.php?id=x]. i'd make not possible, ie. redirect people error page if so, , allow them access page "rewritten" syntax only. what easiest way that? , think necessary measure secure app? rewritecond %{redirect_url} ! ^/app/controllers/product.php$ rewriterule ^app/controllers/product.php$ /product/x [r,l] rewriterule ^product/(.*)$ /app/controllers/product.php?id=$1 [l] the first rule redirect request /app/controllers/product.php no redirect_url variable set clean url. rewrite (last rule) set variable when calling real page , won't redirected.

i have written script stores digital signatures in binaries , script files. question regarding scripts: currently, these signatures stored in 1 single line (a comment) such as: #!/usr/bin/perl print "hello" print " world\n" #signature:asdasg13412sdflsal4sf etc........ the example perl, done scripting languages (perl, python, shell scripts etc.) question is: can trouble if length of line containing signature long? how interpreter handle this? if so, max. line length can use? most scripting languages have long enough limits, if indeed have formal limit on length of lines. posix recommends 2048 minimum. how long signatures? likely, not more 1024...in case, wouldn't worry. if doesn't work language, should report bug rather else.

i looking optimal (time , space) optimal data structure supporting following operations: add persons ( name, age ) global data store of persons fetch person minimum , maximum age search person's age given name here's think of: keep array of persons, , keep adding end of array when new person added keep hash of person name vs. age, assist in fetching person's age given name maintain 2 objects minperson , maxperson person min , max age. update if needed, when new person added. now, although keep hash better performance of (3), think may not best way if there many collisions in hash. also, addition of person mean overhead of adding hash. is there can further optimized here? note: looking best (balanced) approach support these operations in minimum time , space. it looks need data structure needs fast inserts , supports fast queries on 2 different keys (name , age). i suggest keeping 2 data structures, 1 sorted data structure (e.g. balanced b...
