new sage , python, i'm not sure i'm abusing. i'm trying define following function acts on input list a, every time input function affects global value of a. how can make behave locally? def listxgcd( ): g,s,t=xgcd(a.pop(0),a.pop(0)) coeffs=[s,t] while a!=[]: g,s,t=xgcd(g,a.pop(0)) coeffs=[s*i in coeffs] coeffs=coeffs+[t] return coeffs i've tried setting b=a , substituting b everywhere doesn't work either don't understand. need declare sort of sage-y variable thing? def listxgcd( ): b=a g,s,t=xgcd(b.pop(0),b.pop(0)) coeffs=[s,t] while b!=[]: g,s,t=xgcd(g,b.pop(0)) coeffs=[s*i in coeffs] coeffs=coeffs+[t] return coeffs much thanks! you passing reference container object listxgcd function , function retrieves elements container using pop . not scope issue, fact there operating directly on container have passed function. if don't want function modify cont

i have following nsmutablearray: (a|b|c|d|e|255, f|g|h|i|j|122, k|l|m|n|o|555) i trying sort objects in array using last component (255, 122, 555). right have following code: [myarray sortusingselector:@selector(localizedcaseinsensitivecompare:)]; as expected, method sorts array first element (a, f, k). i read nssortdescriptor, example: nssortdescriptor *sort = [[[nssortdescriptor alloc] initwithkey:@"datemodified" ascending:yes] autorelease]; if use it, not clear put parameter in initwithkey . you can use sort descriptor, takes last object of "inner" arrays , sort that. since sort descriptors use key-value coding (kvc), need aware arrays respond valueforkey: in special way - pass normal key on each of objects contain. you need know methods not take parameter and return value can accessed through kvc if normal properties. all adds following: each of objects contained in array (i.e., inner arrays) have key want sort by: last

i love functional programming , love ruby well. if can code algorithm in functional style rather in imperative style, it. tend not update or reuse variables as possible, avoid using "bang!" methods , use "map", "reduce", , similar functions instead of "each" or danger loops, etc. try follow rules of article . the problem functional solution much slower imperative one. in article there clear , scary examples that, being until 15-20 times slower in cases. after reading , doing benchmarks afraid of keep using functional style, @ least in ruby. by other hand feel more comfortable writing code in functional style because smart , clean, tends less bugs, , think more "correct", specially nowadays can use concurrency , parallelism better performance. so confused style use in ruby. wise recommendation appreciated.

basically want make cursor jcomponent that's pixels appear inverse of color over. example, take mouse , hover on letters in url page. if closely, pixels of cursor on black pixels of letter turn white. know can invert rgb color subtracting current red, green, , blue colors 255 each corresponding field, don't know how implement way want. this part of basic paint program making. jcomponent mentioned before "canvas" can draw on various tools. not using java.awt.cursor change cursor because want cursor change dynamically according under it. "cursor" using defined .png image, , creating bufferedimage file can draw on top of existing bufferedimage of whole component. redraw image using point defined mouselistener. i looked alphacomposite , looks close want, there nothing inverting colors underneath cursor want. please help. edit: so had hard way algorithm because there's nothing built in purpose. here's code little out of context: /** * chang

so i'm doing chris pine's "learn program", , i've been having no end of trouble writing own recursive sorting method. i have been making slow (very slow) progress trial , error...but i'm stuck , have no clue. here's code: (and know got lots of other problems, work out in time, want answer question asked below, thanks) array = ['v', 't','k','l','w','o','a','y','p','f','x','g','h','j','z'] sorted_array = [] def mysort(array, sorted_array) if array.length <= 0 return end x = 0 y = 0 while y < array.length if array[x] < array[y] y += 1 elsif array[x] > array[y] x += y y += 1 else y += 1 end end sorted_array.push(array[x]) array.delete(array[x]) puts "test complete" end mysort(array, s

i'm running contest on web image likes wins. it's tiresom having go through 900 images manually want is, sort images tag lets #computer after amount of likes, liked pics on top. have searched net crazy program or site (extragram, gramhoot, statigram, webstagram) none offer sort amount of likes , drives me insane! it's relevant request. i've tried istafeed.js doesn't include images, leaves out ones moest likes defies purpose. there's nothing know of in instagram api sends media sorted likes in advance. don't think there's tool either, writing 1 relatively simple imo , i've done before contest specifically. the simplest thing do following: use instagram api (via library or pure rest) query tag. instance, if care tagged media or want process date, can use [/tag/tag-name/media/recent][1] enpoint. page through each result page processing next_max_id/next_max_tag_id. collect results locally database. receive "like" count eac

my homework assignment asking output sum of specified column of jagged 2d array. i've seen other solutions show how sum of columns, not specific one. issue i'm running java.lang.arrayindexoutofboundsexception if column entered , no element exists in row of 2d array. // returns sum of specified column 'col' of 2d jagged array public static int columnsum(int[][] array, int col) { int sum = 0; // loop traverses through array , adds items in specified column (int j = 0; j < array[col].length; j++) { sum += array[j][col]; } return sum; } // end columnsum() example: ragged array input (class named raggedarray) int[][] ragarray = { {1,2,3}, {4,5}, {6,7,8,9} }; system.out.println(raggedarray.columnsum(ragarray, 2)); this gives me arrayindexoutofboundsexception, don't know how fix if specified column asked argument. ideas? appreciate or suggestions! in loop, a try{ sum += array[j][col]

i trying combination of number. example, input "123" should return ["123", "231", "213", "312", "321", "132"] . here function: function swapdigits(input) { (var = 0; i++; < input.length - 1) { var output = []; var inter = input.slice(i, + 1); var left = (input.slice(0, i) + input.slice(i + 1, input)).split(""); (var j = 0; j++; j <= left.length) { var result = left.splice(j, 0, inter).join(""); output.push(result); } } console.log(output); return output; } however function returns undefined , tell me what's going wrong? the errors for loop , scope have been mentioned. besides that, splice method change string operates on. means inner loop never terminate because left keeps on growing, j never reaches left.length . if new language, suggest starting implementation close algorithm want

is there way use delimiter every other time delimiter symbol comes up? for example, have set of strings separated commas so: (yes, 2, my, 15, face, 9) want word paired number following it, , separate above set following: ((yes, 2), (my, 15), (face, 9)). using custom list this, in realty add each element [ex. (yes, 2]) list. you can use regex pattern. code describes solution (since don't know how want store it, printing out). string data = "yes,2,my,15,face,9"; pattern p = pattern.compile("[^,]*,[^,]*,?"); matcher matcher = p.matcher(data); while (matcher.find()) { string[] splitted = matcher.group().split(","); system.out.println(splitted[0]); system.out.println(splitted[1]); system.out.println("******************"); } this outputs : yes 2 ****************** 15 ****************** face 9 ****************** another solution use scanner delimiter "," , pair returned parts.

i trying create first extension open current url in other/all available browsers. have idea how it? have constructed codes opens current url new tab/new window: chrome.windows.create({url: newtab, type: "normal"}); if not possible, know language can it. unfortunately, chrome extensions cannot execute other programs. did find simple way around however. you need native application running outside of browser accept requests browser extension. did on http on odd-ball port accessible localhost. when button in extension clicked, fires off http request application, can whatever need do. there api communicating native applications chrome extensions, not familiar it.

(am mistaken here?) when cut out detail , edit portion page loads reasonably fast 10+ entries. a solution write detail , edit part once , hide , dynamically shift around according entry. know direct dom manipulation frowned upon in angular. there better solution? a plunkr illustrates idea i looked angular.element , updated secon

i have timeseries dataframe (df) need add column, , pass df function modifies content of time slice of single column. idea follows: rng = pd.date_range('1/1/2011', periods=3, freq='h') df= pd.dataframe([0,0,0],columns=['a'],index=rng) df['b']=0 def v(dff,n): dff.loc[rng[0]:rng[1],:].b=n as far understand python argument passing, call v(df,n) should modify dataframe problem id not time. the following code demonstrates problem: v(df,1) print("ater first: ", df) v(df,2) print("after second: ", df) ('ater first: ', b 2011-01-01 00:00:00 0 0 2011-01-01 01:00:00 0 0 2011-01-01 02:00:00 0 0 [3 rows x 2 columns]) ('after second: ', b 2011-01-01 00:00:00 0 2 2011-01-01 01:00:00 0 2 2011-01-01 02:00:00 0 0 which surprising, because expect column b ether 0,0,0, or first 1,1,0, , 2,2,0. the things stranger if put single print(df) before first call v. c

i have quite time consuming task perform in loop. each iteration independent others figured out use parfor loop , benefit i7 core of machine. the serial loop is: i=1 : size(datacoord,1) %p matrix: person_number x z or p(i,1) = datacoord(i,1); %pn p(i,4) = datacoord(i,5); %or p(i,3) = predict(barea2, datacoord(i,4)); %distance (z) dist = round(p(i,3)); %round distance how many cells x = ceil(datacoord(i,2) / (im_w / ncell(1,dist))); p(i,2) = pos(dist, x); %x end reading around parfor, doubt had use dist , x indexes calculated inside loop, heard problem. error matlab way p matrix used though. how it? if remember correcly parallel computing courses , interpret correcly parfor documentation, should work switching for parfor . any input appreciated, thanks! unfortunately, in parfor loop, 'sliced' variables such you'd p cannot indexed in multiple different ways. simplest solution build single row, , make single assignment p
