I'm not using Swing or something because it makes my binary so slow (in my opinion). The structure is like this: Frame My main-window Containe r Content view of main-window Container -based subviews that including the paint(Graphics g) -method I've added all listeners to My main-window and now I'm

问题 I have inherited some code that is trying to minimize a function using scipy.optimize.minimize . I am having trouble understanding some of the inputs to the fun and jac arguments The call to minimize looks something like this: result = minimize(func, jac=jac_func, args=(D_neg, D, C), method = 'TNC' ...other arguments) func looks like the following: def func(G, D_neg, D, C): #do stuff jac_func has the following structure: def jac_func(G, D_neg, D, C): #do stuff What I don't understand is where

问题 What do you use to minimize and compress JavaScript libraries? 回答1: I use YUI Compressor. Seems to get the job done well! 回答2: I've used YUI Compressor for a long time and have had no problems with it, but have recently started using Google Closure Compiler and had some success with it. My impressions of it so far: It generally outperforms YUI Compressor in terms of file size reduction. By a small amount on simple mode, and by a lot on advanced mode. Simple mode has so far been as reliable as
