i trying find proper signature (current version of typescript 1.7) function should accept reference types, not primitives: function onlyobject(x: ???) { if (typeof x !== 'object') { throw "bad arg!"; } } so function above should work: onlyobject({ }); onlyobject(new date()); onlyobject(new number(1)); onlyobject(null); onlyobject(function () { }); but fail in compile time: onlyobject("awd"); onlyobject(1); onlyobject(false); there isn't way express in language. if you're feeling industrious, can add it , project accepting pull requests feature.

i new python, , learned mutable , immutable objects. appears when swapping elements inside list, python creates copies of individual elements , copy them list. in above example, begin n = [[1, 2], [3, 4]] . first sublist, [1, 2] occupies id# 24 , , second sublist [3, 4] occupies id# 96 . @ first, thought since lists mutable, after swapping, id# 24 holds [3, 4] , id# 96 holds [1, 2] . can see in test above, not case. rather, python pointing objects in manner determined our swap; first slot of list points 96 , second slot points 24 . certainly, id# of n did not change, n did not violate definition of mutable object. way sublists got swapped seems caveat. can kindly confirm or explain in more precise language? you mistaken ids. id#24 id of list [1,2] . not memory address or id of index 0 in n . you might want try example confirm: >>> x = [1, 2] >>> id(x) 4332120256 >>> l = [x, 3] >>> id(l[0]) 4332120256 >>...

i working on facebook app , have little bit of trouble: have index.php , mypopup.php file. hosted on heroku, if matters in way. need when button pressed on index.php page, popup window should appear, content of mypopup.php file, has html form couple of checkboxes , button. now, question how can data popup window (checked items) passed index.php , work data in index.php file? for example: checkbox1 data1 [checked] checkbox2 data2[unchecked] the data related checkbox1 should passed function in index.php you can use javascript this. content show in lightbox. when lightbox done loading, attach event handlers of items want watch in lightbox ( onchange events example). can pass data index.php on back-end using ajax request. also, realized (silly me), if have html form, can change action of form send data index.php instead of mypopup.php. either way work. depends on specifics of data , need it.

how auth0.com authentication feature compared firebase authentication? does auth0.com -free or silver plan- provide authentication feature firebase not provide? thanks there few providers auth0 has aren't available on firebase yet-- namely providers use other oauth. also, rules system available in auth0 can powerful-- writing custom login/user rules using js. you can setup two-factor auth , passwordless login systems auth0, doesn't seem available firebase yet. you can integrate firebase auth0 add-on, allows use both pretty seamlessly. all in all, depends on how far want go user system-- i'd recommend checking out auth0's firebase tutorial , documentation learn more.

i need count bunch of "things" in cassandra. need increase ~100-200 counters every few seconds or so. however need count distinct "things". in order not count twice, setting key in cf, program reads before increase counter, e.g. like: result = cf[key]; if (result == null){ set cf[key][x] = 1; incr counter_cf[key][x]; } however read operation slows down cluster lot. tried decrease reads, using several columns, e.g. like: result = cf[key]; if (result[key1]){ set cf[key1][x] = 1; incr counter_cf[key1][x]; } if (result[key2]){ set cf[key2][x] = 1; incr counter_cf[key2][x]; } //etc.... then reduced reads 200+ 5-6, still slows down cluster. i not need exact counting, can not use bit-masks, nor bloom-filters, because there 1m+++ counters , go more 4 000 000 000. i aware of hyper_log_log counting, not see easy way use many counters (1m+++) either. at moment thinking of using tokyo cabinet external k...
