python - Cast types on the fly while creating dataframe -

August 15, 2012

i have kind of partial json object, dict: { u'20140816 00': {u'var': u'40.78'}, u'20140816 01': {u'var': u'53.24'}, u'20140816 02': {u'var': u'50.23'}, ... } and want put in pandas dataframe. however, change keys string datetime (datetime.strptime(key, '%y%m%d %h') , cast var value string float. is possible while creating pandas dataframe, or if not easiest way recast types json object pandas dataframe. you can use convert_objects method convert strings desired dtypes. normally read_ methods have date handling param , these can handle formats. in case, seeing convert_objects doesn't quite want can call pandas method to_datetime convert column so: df['time_col'] = pd.to_datetime(df['time_col'])

How can I query a joints sao (secondary axis world orientation)? Maya Python -

August 15, 2012

i want query sao of 1 joint can assign another. in case have managed oj of lowarm via .jot , , i'm trying similar sao . mc.joint ('l_hand_jnt', e=1, oj=mc.getattr ('l_lowarm_jnt.jot'), sao='yup', zso=1) any or advice awesome, thanks! i don't think joints have 'sao' attribute: flag there allow specify secondary axis when aligning joint because single orientation not provide enough information maya lay out joint: aim constraint need tell maya how solve given target since there infinite number of valid solutions. you can, however, each 'axis' of joint parsing it's world space matrix or using locators. if extract world matrix of joint using worldmat = cmds.xform(q=true, m=true, ws=true) then joint' x axis pointing along world vector worldmat[0:3] , local y worldmat[4:7] , local z worldmat[8:11] . if want graphically, create locator, parent joint 1 unit along axis checking, , world position - world posi...

node.js - Response returns a 302 instead of a 401 http status -

August 15, 2012

i'm building rest api using express , want add authetication app. on client side have angularjs application. i have code authentication request app.get('/auth/google', passport.authenticate('google')); but code returns 302 http status, isn't helpful in rest api application. guess 401 status code more helpful. i have installed passport-google 0.3 am missing here ? i doubt passport-google has been intended used rest api. 302 redirect status code. passport-google expects /auth/google page has been opened in browser, it's redirecting user google.com authentication dialog. try opening in browser , happen. update: i have feeling picked wrong tool. @ passport-localapikey module , or search other rest authentication solution. i don't think you'll able use passport-google pure rest api without hacking (e.g. monkey-patching internal parts).

both serialization library , developed google developers. there big difference between them? hard work transferring code protocol buffers flatbuffers? i wrote detailed comparison of few serialization systems, including protobufs , flatbuffers, here: https://kentonv.github.io/capnproto/news/2014-06-17-capnproto-flatbuffers-sbe.html however, comparison focuses more on comparing 3 new "zero-copy" serialization systems, , includes protobufs reference point. also, i'm author of cap'n proto, , author of protobufs v2 (i responsible open sourcing protobufs @ google), comparison may biased. note protobufs used throughout google's own services, whereas flatbuffers more of experimental project understand has not been adopted internally.

How to tell PostgreSQL to use other Perl-Version? -

August 15, 2012

im working on ubuntu 14.04 64bit machine. need use perl 5.14 work modules wont install newest version of perl (5.18). postgresql-9.3 server needs install perl 5.18 while installing postgres-plperl. therefore want tell postgres use 5.14 version havent found way that. there way that? you must recompile plperl extension against 5.14 if need this. postgresql links against perl library, , perl libraries aren't abi-compatible across releases, can't substitute 5.14 5.18 @ runtime. you can change perl version used performing install of postgresql source , specifying correct perl install path configure using --with-perl or path env var. or can apt-get source postgresql-9.3 , edit debian/rules use desired perl, edit debian/control specify correct perl dependency, , rebuild package. it makes lot more sense instead fix modules.
