i'm using python 2.7 , pil (pillow) i have script takes rough images of maze , makes cleaner, smaller image. sample input , output: which generated image: in case, script didn't work perfectly, worked pretty well. however, another image of same maze produced result: that's less good. i'm generating images displayed side-by-side looking @ average values each square on 16x16 grid, deciding if square represents black or white pixels. however, since perspective transformation isn't perfect, squares aren't lined up. are there algorithms accuracy? way @ squares of grid aren't square chunks? a piece of code: #this image transformed , thresholded, first half of side-by-side images thresh = image.open('thresholded_image.jpg') pixsize = thresh.size[0]/16 segments = [] in range(16): j in range(16): box = (j*pixsize,i*pixsize,(j+1)*pixsize,(i+1)*pixsize) segments.append(thresh.crop(box)) def blackwhite(image): ...

this may seem simple question, haven't found answer explains behavior i'm seeing. hard provide simple repro case have package structure this: a.b.c a.b.utils i have 1 project has files in a.b.c. (let's call aux_project ) , has files in a.b.d , a.b.utils , etc (call main_project ). i'm trying import a.b.utils inside pytest tests in first project, using tests_require . not work because a.b reason sourced inside aux_project/a/b/__init__.pyc instead of virtualenv , shadows other package (i.e. a.b has c in it, not d or utils ). happens in test context. in ipython can load packages fine, , correctly loaded virtualenv. what's weirder if delete actual directory, tests load pycs virtualenv , works (i need directory, though) python==2.7.9 what going on? ok, problem cwd prepended pythonpath. sys.path.pop(1) (0 tests dir, prepended pytest) resolved behavior.

microservices , cloud thing. talking , writing about. thinking lot topics: how can used benefit from? possible challenges? how can speedup daily development? , how manage things? 1 question bothers me since few days "how manage secrets in microservice / cloud environment?". imagine company 150 software engineers , various teams various products. every team creating software , every service needs various amounts of secrets (api-keys, passwords, ssh-keys, whatever). "old fashion" way create few configuration files in ini / yaml / txt format , read from. 12factor apps say: per env vars. env vars can set per machine , config files can placed there well. works if got hand full of machines , deployment done few system admins. 1 of general rules say: "don`t store secrets in git repo.". now new world comes in. ever team responsible application produce itself. should deployed , run team. our company moving container , self-service way (e.g. mesos , marath...

is there way(settings or extensions) spaces , tabs behave in following way: any long string of spaces or tabs treated single unit. if cursor @ end of string, removes spaces, if single unit. tired of having hit backspace remove spaces @ end of function. ); *<- cursor @ *, ton of space between ; , * takes repeated spaces clear when hitting tab, insert largest amount of space match previous lines columns indentation, excluding empty lines. so this test // , <tab> *// jumps here, rather having hit tab mulitple times. when hitting enter, cursor indents previous indentation amount, using tabs. when starting new block(with {) next line indented, when ending block de-indented. that's want. i've never been able these types of features in visual studio. want tabs 4 spaces default grow or shrink depending on context. backspace consumes whitespace possible on given line, , tab try ali...

i have react component displays multiple pages of content. clicking buttons elsewhere in application should change component displays, given transition. transition custom javascript transition, , not css one, can't use reactcsstransitiongroup . there 2 approaches can think of. both involve passing in transition prop, differ on how next page passed component. option a this option uses presence of transition prop indicate should animate. keeps page1 in it's internal state can still render until transition complete. when completes component dispatches action causes parent component remove transition prop. each of steps render of pager component parent component. // 1 <pager currentpage={page1} /> // 2 <pager currentpage={page2} transition={transition} /> // 3 <pager currentpage={page2} /> option b this option passes in both transition , nextpage explicitly. again component dispatches action when transition complete. // 1 <pager curre...

this question has answer here: change values in multiple columns of dataframe using lookup table 2 answers i have started learning r recently. here's source file working ( https://github.com/cosname/art-r-translation/blob/master/data/grades.txt ). there anyway can change letter grade from, say, 4.0, a- 3.7 etc. without using loop? i asking because if there 1m entries, "for" loop might not efficient way modify data. appreciate help. since 1 of posters told me post code, thought of running loop see whether able it. here's code: mygrades<-read.table("grades.txt",header = true) <- (i in 1:nrow(mygrades)) { #print(i) #for now, see whether replaced 4.0. if(mygrades[i,1]=="a") { mygrades[i,1]=4.0 } else if (mygrades[i,2]=="a") { mygrades[i,2]=4.0 } else if (mygrades[i,3]=="a...
