it important benchmark algorithm before applying specific question. otherwise, garbage in, garbage out. having implemented genetic algorithm (ga) elitism, have no idea how test whether works or not. i have thought printing out statistics, such mean, median, , variance, of each generation. however, not strong indicators of correctness. example, maximum fitness doesn't anything, because random search elitism, have non-decreasing maximum fitness. mean , median not either, because may deteriorate, if ga correct. what effective way of testing if ga working good? my way of deciding if algorithm working draw plot of fitness value on time of execution. this: from question on ga . y-axis fitness level of best individual (less better), x-axis time or number of iterations. ignore red line - not relevant question from graph determine if algorithm stuck in rut , not improve further. however, had advantage of knowing solution , compare solution result of ga execution. ,

this question has answer here: how test randomness (case in point - shuffling) 12 answers testing code has predefined input , output parameters relatively easy when compared writing tests code has portion of randomness, must check if random generator biased or not. an example of library uses random numbers java.util.collections.shuffle(list<?> list) shuffles collection of objects, following http://en.wikipedia.org/wiki/fisher%e2%80%93yates_shuffle . how write junit tests code has random output? not shuffle, testing randomness in general. unless writing actual random number generator or kind of encryption library relies on secure random number generators don't need check if random number generator biased or not. job of author of random number generator. your example of collections.shuffle() poor example because built in jdk method. there&#

before continue writing own infrastructure - possible execute request, have return if it's cached, , return later if cached version not match current version? kind of functionality built-in nsurlcache/nsurlrequest? in other words: request mything.json return cached mything.json display user return again if cached version not current update display you can query nsurlcache directly via cachedresponseforrequest: find out whether in it. can issue nsurlrequest , see whether comes different. i'm not aware of built-in mechanism give first that's in cache whatever fetched, if determines needs fetched , if fetched different.

i thinking useful if property name signaled readonly. take object example: { "id":"12154", "name":"some name", "email":"email@something.com", "joindate":"05/04/2012" } id , joindate of course properties readonly , not allow change through put/post request. there type of convention marking these such? thinking of doing underscores: { "_id":"12154", "name":"some name", "email":"email@something.com", "_joindate":"05/04/2012" } there no naming convention read-only properties in rest. should, of course, feel free establish whatever conventions own api. fiver said in comment, should make sure documented, or conventions combination of (a) confusing, , (b) noise.

i have been working on api , pagination required. 25 elements returned in each request. looking around standards , seem see 2 different things going on. the link header link: http://tools.ietf.org/html/rfc5988 example: link: <https://api.github.com/user/repos?page=3&per_page=100>; rel="next", <https://api.github.com/user/repos?page=50&per_page=100>; rel="last" in json response link: api pagination best practices example: "paging": { "previous": "http://api.example.com/foo?since=timestamp" "next": "http://api.example.com/foo?since=timestamp2" } question: should both? , being said; key "paging" correct key? or "links" or "pagination" i depends on structure of data return (and may return in future). if never have nested objects need own links, using link header (mildly) preferable, because it's more correct. i

i have got input box: <div id="mydiv" class="col-sm-10"> {# autocomplete text box #} <input class="form-control" type="text" name="myautocomplete" id="myautocomplete1"> </div> and have jquery initialise textbox becomes "autocomplete" box, user types in few letters , can select match list. when jquery loads data (there quite bit, 10,000 entries) takes bit of time - maybe 5 seconds. if user types autocomplete box during time, autocomplete doesn't work because data hasn't finished loading. how can add "loading state" input text field? want similar sort of functionality http://getbootstrap.com/javascript/#buttons - after period of time instead of saying "loading..." becomes active. thanks figured out: i made js function: function addloadingtotextbox(textboxes, text, onload) { (i = 0; < textboxes.length

i run test function different modules (in 1 module define function calls c++ code , in other module have same function calls different code). way using py.test? you can use metafunc , create conftest.py file pytest_addoption , pytest_generate_tests functions: def pytest_addoption(parser): parser.addoption("--libname", action="append", default=[], help="name of tested library") def pytest_generate_tests(metafunc): if 'libname' in metafunc.fixturenames: metafunc.parametrize("libname", metafunc.config.option.libname) and in function in tests.py file can use importlib , ask libname: def test_import(libname): import importlib tested_library = importlib.import_module(libname) ....... now, running test should provide name of module want test: py.test tests.py --libname=your_name1 (you can add --libname=your_name2 )

for small project decided give python go first time. got code work fine when handling output of python script noticed strange behavior. it seems terminal setting used influences python's print function outputs. here's simplified version of code: #!/usr/bin/python print 'one two' normal output expect: ~/$test.py 1 2 ~/$ but if try , bash read output, fails. , here's how replicate problem: ~/$ set -x ~/$ ./test.py | while read v1 v2; echo $v1; echo $v2; grep -c "$v1" /myfile; done + ./test.py + read v1 v2 + echo 'one' 1 + echo 2 two + grep -c 'one' /etc/passwd grep: unmatched [ or [^ + read v1 v2 ~/$ set +x notice single quotes around 'one'? , '[' grep complains about. when redirected output file, , loaded in vi, saw control characters in front of output. to fix problem, run command this: ~/$ (term=dumb; ./test.py | while read v1 v2; echo $v1; echo $v2; grep -c "$v1" /myfile; done) this wo

the nub function data.list has o(n 2 ) complexity. it's clear implementing o(n) algorithm doable , not hard. why doesn't haskell it? nub :: eq => [a] -> [a] base data.list o(n^2). nub function removes duplicate elements list. in particular, keeps first occurrence of each element. (the name nub means `essence'.) special case of nubby, allows programmer supply own equality test. to provide answer has been made rather painfully explicit in comments: premise wrong, nub :: eq => [a] -> [a] can not have o(n) implementation. you thinking of implementation can assume ordering, ordnub :: ord => [a] -> [a] , linear log. or perhaps assuming hashable, bucket-sortable sort of thing. unlike eq , when have ordering information don't need potentially compare every pair of elements. this topic discussed in 2008: http://haskell.1045720.n5.nabble.com/ghc-2717-add-nubwith-nubord-td3159919.html this topic discussed again, different actors in co
