i dont understand how nan's being treated in pandas, happy explanation, because logic seems "broken" me. i have csv file, im loading using read csv. have "comments" column in file, empty of times. i've isolated column, , tried varies ways drop empty values. first, when im writing: marked_results.comments i get: 0 vp 1 vp 2 vp 3 test 4 nan 5 nan .... the rest of column nan. pandas loading empty entries nans. great far. im trying drop entries. iv tried: marked_results.comments.dropna() and recieved same column. nothing dropped. confused, i'd tried understand why nothing dropped, tried: marked_results.comments==nan and recieved series of falses. nothing nans... confusing. tried: marked_results.comments==nan and again, nothing falses. got little pissed there, , thought smarter. did: in [71]: comments_values = marked_results.comments.unique() comments_values out[71]: array(['vp', 'te

i writing function calculate duration of overlap between 3 periods, having trouble in finding out how efficiently program this, can me out. i have dataset of people have been followed on time. starting date, , time spent in study differs between participants. each participant, calculate how many days in study in specific year , in 5-year age category was. example, if in study 01-01-2000 01-06-2001, , born on 15-06-1965, contribute 166 days 30-34 year age category in 2000, 200 days in 35-39 year age category in 2000 , 151 days in 35-39 year age category in 2001, while spent 0 days in other categories. in other words: quantify overlap between these periods: a = entering study ending study (varies among participants, fixed value within participant) b = begin specific year end specific year (same among participants, varies within participant) c = entering specific 5-yr age category exiting specific 5-yr age category (varies among participants, varies within part

i'm trying clean file using javascript. file contains lines of text this: a <- b + c / d; i want replace <- = when there string of non-whitespace on either side of <- , separated single space. pretty easy in theory: line = "a <- b + c / d" result = line.replace( /(\s+) <- (\s+)/, /$1 = $2/ ) the above code produces /a = b/ + c / d when run. however, conceptually, should produce a = b + c / d . how can use $1 -style backreferences without allowing javascript opportunity insert slashes willy-nilly? use string second parameter: result = line.replace( /(\s+) <- (\s+)/, "$1 = $2" ); . what happening second parameter being coerced regexp string adds slashes in replacement.

since while i'm implementing services whenever possible servicestack (or webapi) instead of wcf. what want sending interface (-name) server , class-implementation back. maybe that's confusing, i'll give example: my service-client has multiple operations - "check form": logic checking form not implemented. has interface called iformchecker methods nameisvalid(string firstname, string middlename, string lastname) . instead of sending whole form-data server validation, client request implementation of iformchecker server. i know that's possible wcf, have no idea how servicestack. if that's possible, what's way go? checked documentation, i'm not wiser. it seams there's no "magic trick" or anything. have serialize/deserialize class "old-fashion way". if you're interested, here's solution: i created "root"-interface, in example imodule. imodule contains 1 property, called name. string ,

what format of cairo functions arguments. mean coordinates , color rgba arguments. i want use assembly language, c/c++ types not suitable. is 32bit floating point format? also, if "double" 64bit - next question calling convention - how in 32bit stack, 64bit arguments passed? calling conventions vary across different operating systems , different platforms. example, x86 uses stack-based arguments, whereas x86-64 uses register-based arguments. as pushing 64-bit value onto 32-bit stack, you'll need push 2 halves separately - since x86 little-endian push-down stack, you'll need push upper-32 bits first, followed lower-32 bits. to sure, though, can write small c function calls library function in question, compile assembly, , see how handles arguments.

this question concerns various types need defined in required headers of posix/sus standard. some types needs defined in many header files, , i'm wondering what's correct , compliant way of achieving this. for instance, @ <time.h> header specification: inclusion of header may make visible symbols <signal.h> header. this straightforward, <signal.h> included <time.h> . now this: the clock_t , size_t , time_t , clockid_t , , timer_t types shall defined described in <sys/types.h>. as understand it, means can't include <sys/types.h> <time.h> , expose more symbols required. so can confirm this? break standard compliance include <sys/types.h> ? if so, think best solution create specific header each type, particular type can made visible anywhere, without worrying other symbols. is there other solution? and last thing, types c standard? lots of types in posix/sus specification integral typ

this newbee question. forgot add sudo before pip install, , got permission denied message after whole while. there method can make use of downloaded files when invoke pip command sudo subsequently, can save bandwidth. ditto gem install. thanks. no, can't you're asking, @ least not , securely. to want involve changing user ownership of parts of system, bad lot of reasons. or, you'd have change group or add group, bad same reasons first. in both cases, odds of damaging system beyond repair goes way up. we have sudo reason; it's keep running system administrator time , shooting ourselves in foot. invoking command using sudo gives chance pause , think whether want that. adds thin layer of sanity-checking code looks see if safe command issue, can tweak allow/disallow particular actions. if choose go last route, how off-topic stack overflow , should asked on http://superuser.com instead.
