algorithm - Finding the maximum sum from a matrix -

there matrix m rows , n columns. task find maximum sum choosing single element each row , column. came solution, finds maximum whole matrix , sets row , column 0 adds sum , proceeds finding next max. repeats m times. but problem approach if there repetitive elements. i'll try explain example. here matrix.. 3 6 5 3 9 4 9 2 8 1 4 3 4 7 2 5 now, if follow above method.. sum 9 + 7 + 5 + 3 whereas should 9 + 8 + 7 + 3. how solve problem.. i'm stuck update: columns cost of seats can assigned person , rows number of persons. want assign them in such way, max cost. isn't http://en.wikipedia.org/wiki/assignment_problem , typically solved http://en.wikipedia.org/wiki/hungarian_algorithm ? obviously, want maximum rather minimum, surely can achieve maximising costs -(the real cost) or, if worried -ve costs, (max cost in matrix) - (real cost).

python - tkinter call two functions -

-
is possible make tkinter button calls 2 function? some thing maybe?: from tkinter import * admin = tk() def o(): print '1' def t(): print '2' button = button(admin, text='press', command=o, command=t) button.pack() make new function calls both: def o_and_t(): o() t() button = button(admin, text='press', command=o_and_t) alternatively, can use fun little function: def sequence(*functions): def func(*args, **kwargs): return_value = none function in functions: return_value = function(*args, **kwargs) return return_value return func then can use this: button = button(admin, text='press', command=sequence(o, t))

android - Asynchronously processing the attached files in an email (Spring Mail Integration) -

-
if have spring app mail server inbound channel, best way process every file in every email (i poll approx. every 1 min, , fetch 1 email multiple attachments). although can apply multithreading @ receiving channel (simpleasynctaskexecutor or threadpooltaskexecutor) doesn't because if have 10 files attached in email, processing pretty bound 1 thread. i've been keeping pretty synchronous until now, because wanted aggregate data every email, , send response after files have been processed. believe done in better way. in general how can asynchronously process every file in every email, , again asynchronously build email reply? looks asking java.util.concurrent.future . java core concept block until (method) result calculated. (see javadoc example) the spring @async support future concept too. so think need having method uses @async takes 1 attachment of mail argument , returns ever calculated in future. need invoke methods attachments (asynchronous) , stor...

have few questions libusb vs openusb i'm author of project called berry4all allows tethering blackberries via usb. cuurrently i'm using libusb-0.x i'd /need migrate either libusb1.x or libopenusb ... i'm not sure pick some of things need: - linux support - mac osx support (need work , able package it) - python bindings opinions on either , why pick 1 on other. i go libusb-1 because seems architecturally simpler, more actively maintained, more portable , more mainstream openusb. webpage lists successful projects based on it, , small comparison openusb might find useful.
