i encounter error while positioning element. browsers calculate positions of elements looking @ top-left corner. lets point (top-left corner) "basis" (sorry terminology) when using alignment or center object, works fine. if, change element's position other attributes, lets width:%50 , height:%50, browser not move element middle, moves "basis" of element middle. is there way change "basis" other location of element? example, can make "basis" of element right-bottom corner? i think see you're trying ask. in short answer no. if use absolute positioning, , take @ quick test: html <div class="wrap"> <div class="absolute"> </div> </div> css .wrap { position: relative; width:400px; height:400px; background: red; } .absolute { position: absolute; bottom:0; right:0; width:100px; height:100px; background: blue; } you should see div.absolute posi...

for example, extended euclidean algorithm (quoted wiki): function extended_gcd(a, b) x := 0 lastx := 1 y := 1 lasty := 0 while b ≠ 0 quotient := div b (a, b) := (b, mod b) (x, lastx) := (lastx - quotient*x, x) (y, lasty) := (lasty - quotient*y, y) return (lastx, lasty) which tried , got: (defn extended-gcd [a b] (loop [a b b x 0 y 1 lx 1 ly 0] (if (zero? b) [lx ly] (recur b (mod b) (- lx (* (int (/ b)) x)) (- ly (* (int (/ b)) y)) x y)))) i guess find way translate loops deal sequence. how one? how write in clojure way? map, reduce, etc. rather loop recur. for extended euclidean algorithm can use simple recursion, makes function quite elegant: (defn extended-gcd [a b] (if (zero? b) [1 0] (let [[q r] [(quot b) (rem b)] [s t] (extended-gcd b r)] [t (- s (* q t))]))) let's try it: user=> (extended-gcd 120 23) [-...

per the docs , can pass block method expects interface, , block converted anonymous implementation of interface. it's pretty cool! however, have ruby subclass of java class, has method that's supposed return implements interface. // java public abstract class parent { public myinterface getit(); } # ruby class child < parent def getit # need return implementation of myinterface? end end i have tried making proc , lambda , neither of work. can add method parent (in java) forces automatic conversion protected myinterface passthrough(myinterface mi) { return mi; } and works: def getit passthrough {|thing| puts thing.inspect } end this seems hacky though. oversight in how jruby works, or missing alternate solution? yes - should able ... use to_java on proc/lambda : class child < parent def getit lambda { |*args| puts args.inspect }.to_java(java::myinterface) end end

about calculator: basically calculator made calculate resistance of copper , aluminum wires @ ambient temperature using formula r2= r1*(1+alpha(t-25)) here r2 output, r1 value entered user using 4x4 matrix keypad (which include decimal values 12.5 etc), t temperature in degree celsius recorded temperature sensor lm35. alpha copper = 0.0039 alpha aluminum = 0.0042 how should work: basically temperature recorded calculator give input t. value of resistance @ 25deg c fed user using keypad. keys 0-9 , "." used enter value. after when user presses "+" on keypad, should implement formula copper , show result on lcd, when user presses "-" should implement formula aluminum. let leave "*" "/" , "=" buttons spare time being. progress till now: using codes have sent in attachment, able temperature on screen correctly, able see value of r1 (i.e value of resistance @ 25deg c) cannot figure out how use these values output. ...

i'm making "acceleration" array this: acc["0100"] = 1; acc["0300"] = 2; acc["0600"] = 4; acc["0900"] = 8; acc["2000"] = 16; acc["5000"] = 32; and, when user presses key, start timer: this._starttick = (new date()).gettime(); now have timer checks if key still pressed. if so, like: this._delay = (new date()).gettime() - this._starttick; and now, based on this._delay , i'd find 1 of previous values (1, 2, 4 or 8). how that? nb: if value greater " 5.0 " result should 32 . nota: goal is, given elapsed time, find out value best. started way i've explained, if have solution, i'll take it! it's easier operate on array on object: var accarr = []; (time in acc) { accarr.push({time: time, value: acc[time]}); } assuming have array, can do: function getvalue(delay) { var diffs = accarr.map(function (e) { return math.abs(e.time - delay); }); return accarr[...

i have script writing entries hash. however, @ point entries exist in hash think should not. so, i've cocked somewhere, there 1 place think add elements in hash , i've tested make sure these "rogue" elements aren't being added @ location. what break on write hash, this, in "global" kinda way because don't know stray write in code - can't see it... so options? can set watch point in epic debugger , if how? (i've had play can;t find relevant). or perhaps create extended hash can intercept writes somehow? any ideas on "easy" debugging method. otherwise think i'll brute force debug :s in davance... not epic-specific answer, check out tie::watch . can setup variable (like hash) watched, , program can output every time variable updated. updated: tie::trace pretty same thing, simpler interface.

i have rails 3.2 application. locally works fine. but when try make put or delete request on staging, request status '501 not implemented', , response says ' this method may not used .'

this question 1 of online coding challenge (which has completed). need logic how approach. problem statement: have 2 strings , b same super set of characters. need change these strings obtain 2 equal strings. in each move can perform 1 of following operations: 1. swap 2 consecutive characters of string 2. swap first , last characters of string a move can performed on either string. minimum number of moves need in order obtain 2 equal strings? input format , constraints: first , second line of input contains 2 strings , b. guaranteed superset characters equal. 1 <= length(a) = length(b) <= 2000 input characters between 'a' , 'z' output format: print minimum number of moves line of output sample input: aab baa sample output: 1 explanation: swap first , last character of string aab convert baa. 2 strings equal. edit : here first try, i'm getting wrong output. can guide me wrong in approach. int minstringmoves(char* a, char* ...

i have batch script password sitting in part of command requires credentials not want prompt credentials. not worried external threats, don't want co-worker going in there , seeing password. while trust them not abuse it, i'd rather not have there @ all. i able pretty powershell storing secure string in text file. pretty basic, @ least there's no plain text passwords laying around. that's need. how can obfuscate password in batch script? you hide password in alternate data stream : first, add secret password alternate data stream of script: echo somewhatsecretpassword>script.bat:pwd here's how retrieve password variable %p% : for /f "usebackq delims=" %i in (script.bat:pwd) set p=%i from within batch file may use like: for /f "usebackq delims=" %%i in (%~0:pwd) set p=%%i this not secure! please consider: this not secure! alternate data streams not copied everywhere (fat) passwords containing special charac...
