i'm building site reddit. objects sorted rating. hoping me implement pagination. want first load top 20 objects. on click of "next" button, want next 20 objects load based on 20th object's rating. here google docs: https://developers.google.com/appengine/docs/python/datastore/queries?hl=en . does know of way this? or there tutorial out there? this generic function using in order retrieve model instances along cursor. function takes parameters, reading them request. def retrieve_dbs(query, order=none, limit=none, cursor=none, **filters): ''' retrieves entities datastore, applying cursor pagination , equality filters. returns dbs , more cursor value ''' limit = limit or config.default_db_limit cursor = cursor.from_websafe_string(cursor) if cursor else none model_class = ndb.model._kind_map[query.kind] if order: o in order.split(','): if o.startswith('-'): query = query.order(

i have 2 models, 1 of namespaced: group::vote the other of not: vote the namespaced model has class method: def self.get_user_value(voteable) group::vote.where(:user_id => user.current.id, :voteable_type => voteable.class.name, :voteable_id => voteable.id).first.value end strangely, when call method so: group::vote.get_user_value(item) it gets sent named class method in vote model. doing wrong or encountering sort of hopeless bug?

i saw earlier , doesn't make sense me: void generate(std::vector<float> v) { float f = generate_next_float(); v.push_back(f); } if v sent reference or pointer, make sense. instead sent value, , therefore copied function, right? done v useless once function terminates v out of scope, deleted. am right? that is, function generate_next_float() might something, not useless, use of vector here seems pointless. f not depend on it, , nothing returned. yes, far vector concerned, generate() function pointless; changes v won't visible caller. i have feeling author of generate() missed pass reference overlook, not plan :-)

is there way git pull contents of repository without pulling home folder? example have bunch of files in repository called "sample" want pull contents of "sample" local repository called "local." not want pull "sample" such get: local -> sample -> [contents]. there way pull contents? i'm asking because operating on shared web server requires place content under specific folder (and named file names within folder). thanks. edit: wasn't being quite clear before. i'm working on local machine such only allowed change contents of folder , not contents of folder contains folder. option 1:: git clone <repo_path> <folder name> so in case, git clone sample.git local option 2:: the folder-name local repo present not have same of remote. do git clone ... git clone repo_pathorurl then rename folder so instance have sample.git remote repository, do git clone sample.git this clone reposito

is there way extrude 2d graph that's in 3d space 3d geometry actual volume? specifically, i'm trying create simple app play shapes 3d printer (i know there other known programs out there, i'd try myself). i've modified 1 of tutorials @leestemkoski (which awesome way... if you're reading this, thank you!) create mobius strip grapher here . has no volume , can't printed. i'd turn geometry actual volume (a watertight mesh). i've looked @ 2d extrusion examples these . none seem address i'm attempting do. spline example comes close don't know enough know if it's possible adapt purposes. i'm trying tinker examples , @ supporting docs/libraries, i'm having lot of difficulty this. is possible in three.js or going wrong way? thanks mrdoob. realized going wrong way. trying take graphed function , give volume know odd (versus creating real geometry). help!

i have come across several examples of dependencies e.g. include, extend utterly confusing. 1 example dictates include should in direction of; user profile --> login whilst extends should in direction of; validate credit card <-- print receipt. whereas required should in direction of; life of me don't why can't include place order --> create account also matter how these constructed i.e. user profile --> login (include) **vs** validate credit card (extend) ^ | | | print receipt i not sure understand every part of questions, here go: an include goes including included. denotes mandatory sub part of use case : including -----------> included <<include>> extend same include, sub part not mandatory. , unfortunately, arrow other way around. seems puzzle lot. including <----------- optionnally included <<extend>> when speak required, suppose an

let me explain: i'm not asking proper way store specific datetime's timezone in database. i'm talking timezones themselves. example: i have mysql table named 'users'. now, on table, wish have column contains timezone of wherever user lives (this provided user, chosen list). i'm working php, has list of timezone strings these: list of timezones america now, obvious solution (at least me) create varchar column in 'users' table, store timezone string used php in said column. now think it, assume i'll use php interact database table, while true now, might not in future. , (correct me if i'm wrong) php's timezone strings don't work other programming languages, maybe other languages have own 'constants' timezone handling. how approach saving user's timezone preference in db column, then? ideas appreciated. note: useful thing php's timezones that, if dst in effect, automatically take account, awesome. can see inte

i'm using django compress able use less files directly, instead of having convert them css files, works fine except background images paths doesn't translated correctly, reason. the less files linked in base.html this: <link rel="stylesheet/less" type="text/css" media="all" href="{{ static_url }}css/less/style.less" /> the images lives in static/images , less files in static/css/less . in less files link them this: background-image:url(".../images/sprite.png"); ...which should work fine, isn't working @ all. when looking @ rendered css background images paths is: "http://localhost:8000/static/css/less/.../images/sprite.png" what wrong , how can fix it? note: i've tried 1, 2 , 3 dots without luck. since images in static folder have go 2 directory: backgroun-image: url('../../images/sprite.png');

i'm working on library pre-processes less, stylus, etc. preprocessors can both async , sync in nature. because result used in build stage, writing blocking code here not issue. because preprocessors sync, , library expects sync functions down chain, wondering if it's somehow possible wrap preprocessor functions inside sync function can handle both sync , async results preprocessing function? basically possible this, somehow? syncfn = function(contents) { var res = syncorasyncfn(contents, function(err, contents) { res = contents }) // .. magic here waits results of syncorasyncfn return res; // return result function async or sync } sorry, that's impossible. whenever block of code running nothing can run inbetween, i.e. there no real parallelism in nodejs. therefore whatever do: res = contents line can fire after syncfn finishes whatever does, i.e. after synchronous operations finish job in block of code. this forces nodejs programmers use
