I'm trying to prevent the default Ctrl + MouseWheel zoom behavior in Chrome with JavaScript, for the other browsers I use preventDefault() and stopPropagation() in the callback function for mouse-wheel event and works perfect because the other browser always trigger a mouse-wheel event but Chrome does not. Reading the question How to catch Zoom event with GWT and Chrome I found that Ctrl + MouseWheel can be caught as a resize event but after zooming the page so I can't prevent the behavior with this one. Is there other event created before Ctrl + MouseWheel in Chrome or is a bug? Rob W

Suppose I have the following code: interface HumanoidForm { default HumanoidForm reproduce() { <appropriate code for humanoid form reproduction> } } class Android extends Machine implements HumanoidForm { public HumanoidForm reproduce() { <appropriate code for android reproduction> // how to use HumanoidForm's default implementation here? } } Now suppose "appropriate code for android reproduction" is best described by using "appropriate code for humanoid form reproduction" as a sub-routine. How can I access "appropriate code for humanoid form" from within "appropriate code for android

Is there a way to make python3.5 as the default python in AWS. every time i try the next time i connect python2.7 is the default one and pip 6 is the last version, knowing that I did updated it some minutes before. here is the method i followed : amazon_link here is another link of amazon telling the versions, actually they are at 3.5 another_link Thank you in advance, :) best wishes alternatives --set python /usr/bin/python3.5 and then back if you want to alternatives --set python /usr/bin/python2.7 If you want to see what it currently points to alternatives --display python This is a system

I have two tables t1 and t2 . Both have id and name columns. The name column of t1 is defined as not null and it has the default value of 'Peter'. I want to insert all the values from t2 into my t1 table. But I have some null values in t2 table. When I try to insert the values: Insert into t1 select * from t2; It throws this error: Msg 515, Level 16, State 2, Line 1 Cannot insert the value NULL into column 'Name', table 'T1'; column does not allow nulls. Is there any possibilities to set the default value to the column when we try to insert the null value. First Solution, insert into t1 select

I'd like to plot multiple plots in separate bitmap files using the file name pattern (for example, for JPEG) file.%03d.jpg in R. I tried using something like: somevar <- 1 jpg(paste(sep='',filename,'.%03d.jpg')) while(somevar <= n) { plot(data[somevar]) dev.new() somevar <- somevar + 1 } dev.off() but it creates one .jpg file and several Rplotnnn.pdf files. How can I change the default device to jpg , and use the custom file name pattern? I think this should work somevar <- 1 while(somevar <= n) { jpg(sprintf("%s%03.jpg", filename, somevar)) plot(data[somevar]) dev.off() somevar <- somevar + 1

How can one accomplish class-based default value in following scheme? I mean, I would like to inherited classes set default value for "number" differently: class OrderDocumentBase(PdfPrintable): number = models.PositiveIntegerField(default=self.create_number()) @classmethod def create_number(cls): raise NotImplementedError class Invoice(OrderDocumentBase): @classmethod def create_number(cls): return 1 class CreditAdvice(OrderDocumentBase): @classmethod def create_number(cls): return 2 I have looked at this stackoverflow question , but it doesn't address the same problem. The only thing I

I can fully understand ECMAScript 6 has created a lot of potential way of handling with functions such as arrow functions. Since I'm not very familiar with the new stuff, when talking about default parameters for a function. How to interpret the differences between the following way of defining functions: Function 1: function m1({x = 0, y = 0} = {}) { return [x, y]; } Function 2: function m2({x, y} = { x: 0, y: 0 }) { return [x, y]; } The difference is clear when you try passing something to your functions: m1({}) // [0, 0] m1({z: 1}) // [0, 0] m1({x: 1}) // [1, 0] m2({}) // [undefined,
