i'm trying bytes nsdata , put in nsstring. while doing "ffffff" added simultaneously : char *array = (char *)[deviceinfo bytes]; return [nsstring stringwithformat:@"%02x:%02x:%02x:%02x:%02x:%02x", array[5],array[4],array[3],array[2],array[1],array[0]]; returns "53:ffffffcb:ffffffb8:51:09:fffffff0" the issue relates sign extension compiler promotes signed char unsigned int . numbers fffff negative. %x format expects unsigned int argument. declaring array correctly fix issue: const uint8_t *array = [deviceinfo bytes];

similar question , have problems backslash in route parameter. parameter presents windows folder , subfolder structure, contains backslashes. however, every browser (chrome, firefox, ie) converts backslash automatically slash. controller/action/myfolder\mysubfolder\anothersubfolder always becomes: controller/action/myfolder/mysubfolder/anothersubfolder the parameter presents windows folder , subfolder structure, contains backslashes. encode parameter , add in url, in controller can decode original value. encode value using httputility.urlencode(value); decode httputility.urldecode(value);

i made small library in python can generate graphics , i'd able display object in ipython %matplotlib inline . is there library use make work in simple way? bonus points if display can made interactive. from docs on how add rich display of objects: http://ipython.readthedocs.io/en/stable/config/integrating.html#rich-display so long control class definitions, can add _repr_*_ methods, e.g. _repr_png_ or _repr_html_ . note they're surrounded single underscores, unlike python's own magic __repr__ method. text data html should returned string, , binary data png bytes. if don't control class definition, can register formatters separately: get_ipython().display_formatter.formatters['image/png'].for_type(mytype, func) for_type() method docs

i implementing page object pattern in protractor/selenium. since every method in protractor returns promise, consitency methods in page object should return promises. further more page objects may have functions return page object or custom of page object (like leftnavigation, maincontent). instead of returning page object itself, page object should returned within promise. not undestand how that. additionally chain method calls without using .then(..) method. webelements possible call further functions without calling .then(..) method, e.g. browser.driver.findelement(by.css('#someid')).findelement(by.css('#somebutton')).click(); i achieve page object pattern: let pagepromise = adminbasebage.get(); // returns promise<adminbasepage> let mcontent = page.maincontent;// should return promise<maincontent> let titlepromise = mcontent.getmoduletitle(); // returns promise<string> or better adminbasebage.get().maincontent.getmoduletitle();

using xcode 7.3.1, following error when trying commit changes project under svn source control "the working copy "projectname" failed commit files. couldn't communicate helper application" my guess it's failing locate / execute "svn" binary under hood, seem strange other svn actions in xcode work fine (source control -> history... happily shows previous commits etc, suggest able communicate svn server fine) there other similar problems on site, either related git projects or unanswered we got problem when adding new localization. using xcode 8.2.1 we found graphics files @ character in them caused problem. svn doesn't @. when svn operation on file @ in name have add @ @ end of command. seemingly xcode not taking consideration when interacting svn. the workaround temporarily move .svn file project directory, work in xcode, move .svn file , manually update svn using non-xcode interface of choice.

i'm trying implement general fingerprint memoizator : have file can expressed through intelligent fingerprint (like phash images or chromaprint audio) , if our desidered (expensive) function has been computed on similar file, return same result (avoiding expensive computation). locality sensitive hash (lsh) popular , well-performant solution approximate nearest neighbor problem in expensive multi-dimensional space. phash library implements perceptual hashing images. so phash transform multi-dimensional input (an image) one-dimensional object (an hash code), different lsh (again, multi-dimensional objects in lsh). so i'm wondering how implement mono-dimensional lsh phash hash values? or in few words: how can group in bins similar phash values? alternative classic lsh approach (and if not why)? you use n random projections split phash space 2^n buckets, similar images found same bucket. xor hash 64 possible integers hamming weight 1 check neighboring

let's imagine have existential type t t = ∃x { :: x, f :: x -> int} of produce value v :: t v = pack {int, { = 0, f x = 0 } } t so : users of value forbidden know type x used in implementation. in order consume value, code has polymorphic in x the implementor, on other hand, in full knowledge x int , can use capacities of underlying type wishes i know if there variant of mechanism not destroy evidence : w, v = pack {int, { = 0, f x = 0 } } t s = unpack w v -- recovers type information where w value level proof of type equation tying x int . idea selectively reuse implementation in part of code, , have non polymorphic code. have usual existential behaviour, can ignore w returned. i guess 1 cast x int , abandon type safety, that's story: if know secret v , wouldn't make sense me able tell secret else , have compiler verify secret used code has been given to. has been tried / what's wrong part of this? use singletons

i have task list file in hdfs , list of tasks cpu-bound , executed in small 5-node cluster hadoop mapreduce (map only). instance, task list file contains 10 lines, each of corresponds task command. execution of each task takes way long time, more efficient execute listed 10 tasks in parallel on 5 nodes. however, task list file pretty small, data block located on 1 node node execute these 10 tasks based on data locality principle. there solution ensure 10 tasks executed in parallel on 5 nodes? by default, map reduce run 1 mapper per split. split block, if have large file, 1 mapper per block size of file (default 128mb) process 128mb chunk in parallel other chunks. in case, have series of lines in small file - 1 split, , therefore processed single mapper. however, instead of having 1 file of 10 lines, can create 10 files of 1 line? have 10 splits, , map reduce run 10 mappers across cluster in parallel (depending on available resources) process tasks.

consider following example. struct astruct{ var = 0 } class aclass{ var = 0 var a: = a(i: 8) func astruct() -> astruct{ return } } if try mutate the variable of instance of class aclass compiles successfully. var ca = aclass() ca.a.i = 7 but if try mutate return value of astruct method, compile screams ca.astruct().i = 8 //compile error. cannot assign property: function call returns immutable value. can explain this. this compiler's way of telling modification of struct useless. here happens: when call astruct() , copy of a passed you. copy temporary . can examine fields, or assign variable (in case able access modifications back). if compiler let make modifications temporary structure, have no way of accessing them back. why compiler programming error.
