Is it possible to link IPython widgets less naively? -

-

i'll start simple example of i'm trying do:

say, have 2 intslider-widgets. have 1 represent x , other x^2 (unidirectional link). maybe want first slider display sqrt(x^2), if play second slider (bidirectional link).

this would,very naively, translate in this:

l1 = traitlets.link((widg1, 'value'),(widg2, 5* 'value'))

which of course doesn't, because second tuple argument supposed string, passing 'valuevaluevaluevaluevalue'.

anyway, possible , if yes, has been implemented?

link passes on same value. if want transform value, need callback:

def widg1_changed(name, new_value):     widg2.value = 5 * new_value  widg1.on_trait_change(widg1_changed, 'value')

i don't know of way bidirectionally @ present.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
