            QUESTION

            How can I write a code that loops 256 times using only 3 instructions and one 8-bit register (8086 instruction set)?
            Asked 2022-Mar-07 at 19:25

            This was a question that was previously posed by a prof of mine and I'm assuming the 8-bit register is either CL or CH. I got it working by simply moving 01H to the CH register, but I was wondering if there was any other way of doing this since I am technically using the 16-bit CX register as a whole when running the code.

            My code for reference :

            Answered 2022-Mar-07 at 19:25

            You're right, your code uses 16-bit CX. Much worse, it depends on CL being zero before this snippet executes! An 8-bit loop counter that starts at zero will wrap back to zero 256 decrements (or increments) later.

            This is a way of doing this: for the holes at the start and the end of the ticket you can use the before and after elements. Both pseudo elements are transparent with a big white box shadow: box-shadow: 0px 0px 1px 50vw white;. Since the .dashed element has overflow:hidden you will see the box shadow of the pseudo elements only inside the .dashed and will look as if the .dashed has a white background.

            For the outer shadow you can now use a drop shadow filter as you intended.

            Is it possible to not reorder elements when using d3.join?
            Asked 2022-Feb-18 at 23:13

            In d3, we may change the order of elements in a selection, for example by using raise.

            Yet, when we rebind the data and use join, this order is discarded.

            This does not happen when we use "the old way" of binding data, using enter and merge.

            See following fiddle where you can click a circle (for example the blue one) to bring it to front. When you click "redraw", the circles go back to their original z-ordering when using join, but not when using enter and merge.

            Can I achive that the circles keep their z-ordering and still use join?

            ...

            ANSWER

            Answered 2022-Feb-18 at 23:13

            join does an implicit order after merging the enter- and update-selection, see https://github.com/d3/d3-selection/blob/91245ee124ec4dd491e498ecbdc9679d75332b49/src/selection/join.js#L14.

            The selection order after the data binding in your example is still red, blue, green even if the document order is changed. So the circles are reordered to the original order using join.

            You can get around that by changing the data binding reflecting the change in the document order. I did that here, by moving the datum of the clicked circle to the end of the data array.

            This is a common mistake that happens when using Inherited Widgets like MediaQuery. Now you may not be using it explicitly but from your description it seems that Flutters' showModalBottomSheet method maybe using it.

            The error is telling you that no MediaQuery ancestor(i.e. WidgetsApp, CupertinoApp or MaterialApp) could be found above context. It means above this context:

            cursor color - smooth transition between diferent backgrounds
            Asked 2022-Jan-24 at 19:19

            On a website I'm creating there is a cursor that needs to change its color smoothly.
            When it is on a white background the cursor needs to be the blue #0059ff (this is important and I will explain why later on) and when it is on blue then the cursor needs to be white; and the transition needs to be smooth like so:

            To get the white color with mix-blend-mode I'm calculating the inverted color using adjust-hue($color, 180) (in SCSS) and applying this color to the cursor.

            When the background color is #0000ff then cursor should be #ffff00.

            I have started a prototype using mix-blend-mode: difference that works on "primary colors" (basically colors like #ff0000, #ff00ff and so on).
            Result:

            Problems begin when I try to change the "primary" blue #0000ff to the one needed by the project #0059ff. The inverted color is calculated to be #ffa600 and the result is, let's say, "unsatisfactory" because I want the cursor to be white on some background color and said color on white background.

            Calculating the difference will not work with this color and I have no idea how to make it so that when the cursor is not over the white background then the cursor becomes blue (-ish) and when it's over the blue background it becomes white.

            My whole code so far:

            In this case, the mix-blend mode is very limiting. When you want to have completely unrelated colors then it's not possible to use it.

            Answered 2021-Nov-27 at 04:03

            This is very close to working, so don't get discouraged. There are two minor problems:

            1. When you call move recursively, you have to pass v again. So let newCirc = move f1 v is correct instead of let newCirc = move(f1). (Note that newCirc might not actually be a circle, so you might want to use a different variable name.)

            2. Since point is just a synonym for int * int, it doesn't have its own constructor function. So (cx + vx, cy-vy) is correct instead of point(cx + vx, cy-vy).

            When I made these two changes, your code worked correctly for me. There are a number of other issues with your code that you might want to address, but those are the only two that are show-stoppers at this point.

            The problem is you are constructing the ImageViewer with another QGraphicsView that you made in Qt Designer, "qgraphic_image", as its parent. This makes it a child widget inside of that parent graphics view, and it's effectively invisible as its viewport rect has no size (that is why you got a division by 0 error).

            You can remove the "qgraphic_image" from your UI file, for now I just replaced it in the layout to try it:
