is there way rename single file in npm scripts? want prepare files distribution, need built files named differently in source... i have tried orn, seems work on command line, not npm script. i'm looking add cross-platform dependency project, rather writing own javascript script copy files over. my ideal solution can include in package.json , 1 line command, e.g. rename old-file-name new-file-name sure. npm script can run node js file want. for example: require('fs').rename(oldpath,newpath) more info: https://nodejs.org/api/fs.html#fs_fs_rename_oldpath_newpath_callback https://docs.npmjs.com/misc/scripts

when creating custom control extends textbox, inside oncreatecontrol() override, parent null. when extending other controls such button, isn't null. checking following code , adding form , various container controls: protected override void oncreatecontrol() { base.oncreatecontrol(); messagebox.show((parent == null).tostring()); //true when extending textbox, false when extending button } what can retrieve parent of control when added control, ensuring same code work regardless of control extend?

here snippet. when pattern matching, compiler emits no warning. know workaround ? i compiler emit warning when forget case when pattern matching against simpleexpr.expr , otherexpr.expr . construct allows me factor nodes common both expression trees (like if ) trait hierarchy { sealed trait expr } trait if { this: hierarchy => case class if(cond: expr, yes: expr, no: expr) extends expr } trait word { this: hierarchy => case class word(name: string) extends expr } object simpleexpr extends hierarchy if word //object otherexpr extends hierarchy if integer object demo extends app { import simpleexpr._ def func(expr: expr) = expr match { case if(cond, yes, no) => cond // compiler should emit warning } } because sealed isn't transitive, it's not clear me whether lack of compile error bug or not. i noticed adding case match expression causes compiler issue "unreachable code" warning. here's modified version of co

i make application, have 2 pictures(layers) , can erase part of foreground image(using tapping , finger painting). make this, had used scratchview library android. android-wscratchview this give opportunity erase parts of images. next step - "anti erase". must use finger draw, , restore parts of image have been erased. dont understand how it. may possible change method of library class , have opportunity "anti erase". may should create special handler this. had tried done long time, , hope can me in this. thanks! i guess article should this: http://www.41post.com/4794/programming/android-rendering-a-path-with-a-bitmap-fill there can see how draw path filled bitmap. rest pretty straightforward: assign bitmap (top layer image) paint in above article. in "motionevent.action_down" add path not mpathlist, other, say, npathlist. in "ondraw" go through npathlist , draw paint article above.

i want create 2d plot of hilbert spectrum. want time vs frequency plot, amplitude of signal represented color changes in plot. what have done this , need this . thank in advance edit: i have values of amplitude , instantaneous frequency on time, have produced using hilbert huang transform. let's use first imf, , have 100 samples. have is: instantaneous_frequency = [f1 f2 f3 ... f100] instantaneous_amplitude = [a1 a2 a3 ... a100] time = [t1 t2 t3 ... t100] what need way plot them second image, without using spectrogram function, since uses stft , have applied hht. the code producing first plot is: time_window = 1:101; signal= rand(1,101); hilb = hilbert(signal); inst_amp = abs(hilb); inst_th = angle(hilb); inst_freq = diff(a_inst_th)/(1/256)/(2*pi); %instantaneous frequency %inst_freq = remove_outliers(inst_freq,time_window(1:end-1)); inst_freq(end+1) = inst_freq(end); % done due diff() plot(time_window*4,inst_freq,'k.','markersize

i using h2o r package (2014 version) perform deep learning task using textual data. did research in 2015 , obtained promising results using deep learning method (function - h2o.deeplearning; e.g. fscore , recall achieve >0.9). found original r code doesn't work (due change of h2o package in nov 2015) , revised code. however, when tried run same deep learning model (same setting), not achieve outperfom results anymore!! please, wish know if h2o has changed internal modeling settings since revision of h2o package? wish reproduce old results new package... please kindly help. h2o deep learning (2.0 , 3.0) not reproducible default -- can change setting reproducible = true , slow things down quite bit, reproducibility requires code run on single core. therefore variability due randomness in algorithm alone, rather upgrade of h2o 2.0 3.0. if want use h2o classic (2.0), old code still work, is. might try running first see if can track down source of variability. there
