trying come-up pseudocode (in latex) algorithm takes 2 graphs input - compares each node in graph - (i fill in comparing function), returns 0 if node 1 graph equal node in other graph, else returns 1. node in graph graph. checking recursive. what's mean , comparing graphs ? graphs of g1 , g2 same if of vertices have same weight[value] , |g1| = |g2| . (in simple graphs)

i'm in process of developing website not-for-profit organization, , thought wordpress great tool use base cms site. building site wordpress has not been problem, have been having difficult time finding plugin use them organize , advertise upcoming events. currently, use google calendar, trying move integrates more cleanly site. essentially, need wordpress events/calendar plugin these features: + add reoccurring events start , end time + each event should have own page (reoccurring events should shown single page) + display events in mini-calendar , full calendar/list view it nice have these features: * ability categorize/tag events * ability add picture go event i'm indifferent on these features: - being able rsvp - paying events - import/export calendars there many events/calendar plugins out there wordpress, can't seem decide 1 worth me spending time use website. suggestions? you can create category called "events" , desig

i working on parallelization algorithm, following: read several text documents total of 10k words. create objects every word in text corpus. create pair between word-objects (yes, o(n)). , return frequent pairs. i parallelize 3. step creating pairs between first 1000 word-objects rest on fist machine, second 1000 word-objects on next machine, etc. my question how pass objects created in 2. step mapper? far aware would require input files and hence need serialize objects (though haven't worked with before). there direct way pass objects mapper? thanks in advance help evgeni update thank reading question before. serialization seems best way solve (see java.io.serializable). furthermore, have found tutorial useful read data serialized objects hadoop: http://www.cs.brown.edu/~pavlo/hadoop/ ). how parallelize steps? use #1 text documents input mapper. create object every word in mapper. in mapper key-value pair word-object pair (or object-word depending on

we have been trying implement shortcodes on asp.net mvc web app allow users uniquely invoke given article/page using assigned short code. for e.g.: www.mysite.com/power map actual url: www.mysite.com/power/home/. i have created various routes throughout site map these shortcodes various actions , controllers within application. shortcode/route point of view, working great. i, however, noticed couple of interesting things. have hyperlinks use url.action method generate url pointing pages. many of these pages have short codes associated them. e.g.: have link says: <a href="<%= url.action("index", "home", new { area = "power" })%>"> go power page</a> this page has mentioned short-code assigned it. when use url.action, ideally expect create link /power/home/index or /power/home, since have route constraint mapped it, generates link /power. is there way can use actual link url when generating links? want short-codes

i'm reading , hearing pain points , wondering if should go route. not mention, cannot seem find definitive documentation (from microsoft). if shouldn't use it, route suggest? i'm trying new site off ground, want right first time. i should choose use webgrid if looking , display data , not have rely on external libraries. however, if you're looking fully-featured grid, not go webgrid right now. there difficulties in applying styles , doing more advanced aspects available in other popular web grid libraries. as opinion on should use - if webgrid not meet needs, check out jqgrid . it's popular package , works amazingly , easy setup , run. if more documentation on webgrid , check out microsoft's asp.net mvc 3 tutorial site.

i found article on image processing here: http://www.switchonthecode.com/tutorials/csharp-tutorial-image-editing-saving-cropping-and-resizing works fine. i want keep high quality when resizing image. think if can increase dpi value can achieve this. know if possible? , if so, how can implement in c#? for starters, it's worth pointing out there 2 general categories of images; vector [e.g. svg, wmf, adobe illustrator , corel draw graphics] , bitmap (also called raster) images [e.g. bitmap, jpeg , png images]. vector images formed series of mathematical equations and/or calculations. bitmap images, on other hand, made of individual dots (pixels) each corresponding particular feature on object image taken of. if should happen want resize image, first thing consider if bitmap or vector image. virtue of fact vector images obtained calculations, can resized without losing detail. case different bitmap images. since each pixel independent of other, when desire resize it

i'm getting started jenkins ci, , had question i'm struggling find answers in docs or online. wonder if might able offer advice? i'm attempting use automatically deploy dev , stage branches of django projects hosted on github organisation repository (ie, private). @ moment have user "django" can access github repo via github deploy key. jenkins user can't access repo. what's best practice way of dealing - should creating ssh deploy key "jenkins" user, or should getting jenkins run "django" user? i've seen mention if hudson_user in newsgroup post, can't find reference in docs. many thanks! ludo. i have not worked github , answer may not apply @ all, use jenkins , use both cvs & subversion source control. in our system, use different username/password combinations 3 (jenkins, cvs, subversion), , has had no adverse effects yet (it has been year since deployed hudson - building 50+ projects). as long

i see lot of confusion between hashes , encryption algorithms , hear more expert advice about: when use hashes vs encryptions what makes hash or encryption algorithm different (from theoretical/mathematical level) i.e. makes hashes irreversible (without aid of rainbow tree) here similar questions didn't go detail looking for: what difference between obfuscation, hashing, , encryption? difference between encryption , hashing well, in wikipedia ... since want explanation, i'll best here: hash functions they provide mapping between arbitrary length input, , (usually) fixed length (or smaller length) output. can simple crc32, full blown cryptographic hash function such md5 or sha1/2/256/512. point there's one-way mapping going on. it's many:1 mapping (meaning there collisions) since every function produces smaller output it's capable of inputting (if feed every possible 1mb file md5, you'll ton of collisions). the reason hard (or im

the boost::hash_combine template function takes reference hash (called seed ) , object v . according docs , combines seed hash of v by seed ^= hash_value(v) + 0x9e3779b9 + (seed << 6) + (seed >> 2); i can see deterministic. see why xor used. i bet addition helps in mapping similar values apart probing hash tables won't break down, can explain magic constant is? the magic number supposed 32 random bits, each equally 0 or 1, , no simple correlation between bits. common way find string of such bits use binary expansion of irrational number; in case, number reciprocal of golden ratio: phi = (1 + sqrt(5)) / 2 2^32 / phi = 0x9e3779b9 so including number "randomly" changes each bit of seed; say, means consecutive values far apart. including shifted versions of old seed makes sure that, if hash_value() has small range of values, differences spread across bits.

consider following (linqpad) example. tostring in class x marked virtual. why output here not equal "hi, i'm y, hi, i'm x" instead typename printed? of course marking tostring virtual wrong, because defined in object virtual, trying understand happening here. void main() { y y = new y(); console.writeline(y); } // define other methods , classes here class x { public virtual string tostring() { return "hi, i'm x"; } } class y : x { public override string tostring() { return "hi, i'm y, " + base.tostring(); } } that's creating new virtual method in x called tostring() hides object.tostring() . if have: y y = new y(); x x = y; object o = y; console.writeline(y.tostring()); // shows "hi, i'm y, hi, i'm x"; console.writeline(x.tostring()); // shows "hi, i'm y, hi, i'm x"; console.writeline(o.tostring()); // calls object.tostring; shows "y" c

in traditional way of thinking (remember dna ?) we're supposed architect our application separating layers services. when implementing asp.net mvc application, why should implement service , wrap wcf references separate dll, rather having web application reference wcf directly? i can think of 2 arguments, , thoughts on those: keep code in once place (well, still done when have wcf!) reusable service when other systems need service (well, if internal application?) on other hand, people might argument over-architecture implementing alot of layers bring more complexity solution , not yield benefits expected. i'm not fan of introducing dlls "because". been there; ot t-shirt dependency graph on it. if can't define benefit in environment/context , simplest thing - may reference web app. i've heard argument of allowing re-use, counter: soap/mex pretty-much defining this. argument testability, isolation, separation etc; , depends on how benefit

why not working, doing wrong? >>> p1 = r'\foo\bar.txt' >>> os.path.join('foo1', 'foo2', os.path.normpath(p1)) '\\foo\\bar.txt' i expected this: 'foo1\\foo2\\foo\\bar.txt' edit: a solution >>> p1 = r'\foo\bar.txt' >>> p1 = p1.strip('\\') # strip '\\' path not absolute >>> os.path.join('foo1', 'foo2', os.path.normpath(p1)) 'foo1\\foo2\\foo\\bar.txt' when os.path.join encounters absolute path, throws away has accumulated far. absolute string 1 starts slash (ans on windows, optional drive letter). normpath won't touch slash has same notion of absolute paths. have strip slash. and if may ask: come in first place?

okay, in nutshell, need automatically apply set of sorting criteria , data filters jqgrid when loads. intent user start 10 pre-filled filters , then, if choose, can alter filters or sorting see fit. so far, google-ing, trial , error , sweat, have following working: -> can load/save sort column & sort order in session cookie. -> can load search dialog pre-defined search filters. after grid loads, can open modal dialog , see proper filters , if click "find" appropriate data posted server , right results returned screen. the thing biting me in butt right is, think, easy part, escapes me. can't seem either of following: ( ) ideal thing if attach these filters grid , it's post data in advance of initial load there single trip server. ( b ) workable solution, though less ideal, grid load first page of unfiltered data first, , apply filters , re-query server filtered data. since can manually click "find" button today , works, though

i want iterate through set of specific values. simple example below program project1; {$apptype console} var a, b: word; wait: string; begin := 0; b in [1,5,10,20] begin := + 1; writeln('iteration = ', a, ', value = ', b); end; read(wait); end. the sample code here expect , produces following iteration = 1, value = 1 iteration = 2, value = 5 iteration = 3, value = 10 iteration = 4, value = 20 now if change order of set b in [20,10,5,1] the output same original, order of values not preserved. what best way implement this? sets not ordered containers. cannot change order of set's contents. for-in loop iterates through sets in numerical order. if need ordered list of numbers, can use array or tlist<integer> . var numbers: array of word; begin setlength(numbers, 4); numbers[0] := 20; numbers[1] := 10; numbers[2] := 5; numbers[3] := 1; b in numbers begin inc(a); writel

im trying use jquery on page loaded div using .load(). php gets loaded div, contains div hidden section hidden when first shown. when link pressed hidden div section slides out. works fine reason div slides finishes sliding down , cant figure out why. $(function() { //load addfood.php div user-main //this works , div hidden when addfood.php loaded page $("a[name=search]").click(function() { $(".user-main").load("addfood.php", function(){$("#addfood .addfood-body").hide();}); // here link clicked inside newly loaded div slidedown hidden div // div slides down comes right after $('a[name=openaddfood]').live('click', function() { if ($("#addfood .addfood-body").is(":hidden")) { $('img[name=openaddfood]').addclass('rotate'); $('#addfood .addfood-body')
