i've noticed when try generate list of sequences : operator (without anonymous function), sequences reversed. take following example. x <- c(4, 6, 3) lapply(x, ":", = 1) # [[1]] # [1] 4 3 2 1 # # [[2]] # [1] 6 5 4 3 2 1 # # [[3]] # [1] 3 2 1 but when use seq , fine. lapply(x, seq, = 1) # [[1]] # [1] 1 2 3 4 # # [[2]] # [1] 1 2 3 4 5 6 # # [[3]] # [1] 1 2 3 and help(":") stated for other arguments from:to equivalent seq(from, to) , , generates sequence from to in steps of 1 or -1. why first list of sequences reversed? can generated forward sequences way colon operator lapply ? or have use lapply(x, function(y) 1:y) ? the ":" operator implemented primitive do_colon function in c. primitive function not have named arguments. takes first parameter "from" , second "to" ignorning parameter names. see `:`(to=10, from=5) # [1] 10 9 8 7 6 5 additionally lapply function passes it's value...

i doing scientific calculations on images in c , use imagemagick read file , output 8 bit quanta raw rgb file analyze. seeing recurring squares in output , garbled, fuzzy regions. suspect integer truncation causing artifacts. after read entire 8 bit, rgb file memory, allocate parallel array of unsigned shorts hold intermediate results during analysis. calculations done doubles , stored unsigned shorts can used in other calculations. @ end, shorts dumped disk , read either photoshop or imagemagick raw, 16 bit rgb images. with 8 bits of input data, granularity chunky on darker areas single digit rgb values common. when working 8 neighboring data points in operation such averaging them all, can store full values of points , still have 16 - 8 - 3 = 5 bits left before overflowing unsigned shorts. experience, ugly, muddy, mangled areas when overflow causes loss of higher level bits. i plan on upgrading input full, 16 bit, unsigned short, tiff type quanta. upgrading parallel, workin...

i new in hadoop , working on hadoop. have small query. i have around 10 files in input folder need pass map reduce program. want file name in mapper filename contains time @ file got created. saw people using filesplit file name in mapper. if let input files contains million of lines every time mapper code called, file name , extract time file, obvious repeated time consuming thing same file. once time in mapper not have again , again assign time file. how can achieve this? you use mapper's setup method filename, setup method gaurenteed run once before map() method gets initialized this: public class mapperrsj extends mapper<longwritable, text, compositekeywritablersj, text> { string filename; @override protected void setup(context context) throws ioexception, interruptedexception { filesplit fsfilesplit = (filesplit) context.getinputsplit(); filename = context.getconfiguration().get(fsfilesplit.getpath().getparent().getname())); } @o...

i have split jpeg image r,g,b , converted them numpy arrays. changed pixel values of r,g,b. want merge these 3 1 jpeg , save it. original image 1024 * 500 image. if can give me idea, great help im =image.open("new_image.jpg") r,g,b=im.split() r=np.array(r) g=np.array(g) b=np.array(b) then changed values of pixels. want merge resulting r,g,b. in advance based on document (page 4 in end), can merge: r, g, b = im.split() im = image.merge("rgb", (b, g, r))

the yesod book says the encryption prevents user inspecting data, , signature ensures session can neither hijacked nor tampered with. it's not clear me why case. if eavesdropper gets hold of cookie sent server , uses before legitimate user makes request, won't session end being hijacked? it seems me way prevent session hijacking use ssl throughout. if signing , encryption done yesod ends being unnecessary overhead (edit: overhead far preventing hijacking concerned. @sr_ points out in comments, still useful otherwise). that's catch. used more accurate, when include ip address of client in cookie prevent hijacking. combined anti-tampering protections, made impossible mitm attack work unless nated behind same router or using same proxy. unfortunately, had disable protection due concerns proxies well. it's possible single user's requests come multiple ip addresses due intermediate proxy servers. don't have data tell how happens, there e...

near end of chapter 3 of common lisp language, steele writes "constructs use lexical scope generate new name each established entity on each execution. therefore dynamic shadowing cannot occur (though lexical shadowing may)". confused means "dynamic shadowing cannot occur". example of "dynamic shadowing" like? here example of might have meant: (defun f (g) (let ((a 2)) (funcall g a))) (let ((a 1)) (f (lambda (x) (- x a)))) this returns 1 in common lisp because lexical binding of a in f not affect binding of a in top-level let , so, when f calls g , subtracts 1 2 because lambda gets a top-level binding. contrast dynamic binding in emacs lisp, return value 0 . you might find instructive work out contorted-example , try in cl , elisp.

i can strip html correctly out of string doing this: htmltotext = function(html){ return jquery(html).text(); }; but there cases html string containing styling like: <style type="text/css"> .button:hover { background-color: #6b6d71; } </style> the function strip <style> tags text end with .button:hover { background-color: #6b6d71; } i'll know if jquery able strip styles , how. you can use .clone() , remove style tags using .remove() . var $foo = $('.foo'), $fooclone = $foo.clone(); $fooclone.find('style').remove(); $('#output').text($fooclone.text()); here small demo: http://jsbin.com/lamasabapu/1/edit?html,css,js,output

i have built banner multiple canvas (position: absolute, different z-idexes) but... i'd liek re-create teh whole thing 1 canvas , proves problem. banner's animation quite complex here brief question taht me understand how works. i'd "cut" hole in black rectangle red 1 becomes visible here code: red.beginpath(); red.fillstyle = '#af0000'; red.fillrect(33, 33, 200, 60); // drawing red rectangle red.closepath(); red.beginpath(); red.fillstyle = '#000'; red.fillrect(77, 66, 120, 60); // drawing black 1 red.clearrect(110, 80, 20, 20); // cutting 20x20 pixels rectangle red.closepath(); i know why both rectangles affected. illustrate i'd achieve. make 2 canvas - draw red rectangle on 1 , black on another, , cut black 1 - i'd 1 canvas only. - know re-draw red part doubt that's wise solution. here fiddle: http://jsfiddle.net/hej11px9/ thanks in advance! i know quite amateurish questio...
