QUESTION
Server: MariaDB 10.4.17
INSERTing a POLYGON with 14 digits to the right of the decimal point, then SELECTing the same data, returns a POLYGON with 15 digits to the right of the decimal point, which is more data than actually exists, and the excess precision is incorrect.
INSERTing a 0-padded POLYGON with 15 digits to the right of the decimal point, then SELECTing the same data, returns a POLYGON with 15 digits to the right of the decimal point, however the SELECTed data is incorrect in the last digit and is not the 0 used for right-padding.
Because the table data is incorrect, the various Geometry functions like ST_Contains() produce incorrect results. This appears to be some sort of floating point type of error, but I'm not sure how to work around it.
Is there any way to make MariaDB save, use and return the same data is was given?
Example:
...ANSWER
Answered 2021-May-18 at 19:37I think the precision you have is reaching the limit of the 64-bit floating point, and what you get is really the nearest floating point value representable by CPU.
The code below prints the input value without any modification, and then the very next double floating point values decremented and incremented by smallest possible amounts:
QUESTION
As I alluded to in my previous post on the subject (Multi-line flutter text field occupies all of Flexible space with ugly right padding) I'm a bit of a perfectionist. Unfortunately my flutter layout-fu isn't as strong as my ambition. I'm creating a messaging app, and I'm working on adding a timestamp to the message box. My code so far (thanks also to this answer: Complex alignment of a sub widget based on wrapping text like in the Telegram chat messenger) is this:

...ANSWER
Answered 2021-Apr-13 at 06:18Example: Message box with Timestamp
I think you can try this way:
- Calculate/Simulate text and check the message is overlapping the timestamp.
- If it overlaps, add
\n
to change the line. Otherwise, return the original one.
You need the following things:
LayoutBuilder
: BoxConstraint above the text widgetTextPainter
: Simulate the layout (also need theTextStyle
,textWidthBasis
or there may affect the layout result)

QUESTION
I want to show an horizontal scroll indicator for a scrollable DIV container.
After some testing I'm pretty sure that it's not possible wit pure CSS. I found a snippet in an answer for a similar question. Unfortunately I couldn't figure out how to change the script to my needs.
I'm using a simple DIV container with some elements in it. Here's my code:
...ANSWER
Answered 2021-Jan-18 at 21:56You can have your own custom horizontal scroll behavior with vanilla js, you just need to handle mousedown
, mouseup
and mousemove
events, calculate the needed scroll value and move your elements using transform: translateX()
style, and to keep track with these values,
I did some changes and added some js code, check the snippet bellow:
QUESTION
I am working on a horizontal scroll bar with right and left arrows for smooth scrolling. The idea is I'm getting getMenuPosition() + '100' to scroll left, and it does work on first click, but not on a second one. For right scrolling with getMenuPosition() - '100' it works as expected. I need to make the scrolling for right and left progress by 100 each time a user click on the arrow. Any help will be much appreciated !
...ANSWER
Answered 2020-Dec-21 at 07:51Your code failed because in JavaScript '100' + 100 === "100100"
. Change the line scrollLeft: getMenuPosition() + '100'
to scrollLeft: getMenuPosition() + 100
solve the problem.
https://jsfiddle.net/k0egf12a/8/
I don't understand why you are adding a string to a number. You probably should avoid doing things alike. Thus, you should change scrollLeft: getMenuPosition() - '100'
to scrollLeft: getMenuPosition() - 100
as well.
QUESTION
In my application, there are multiple cards and left/right paddles. For normal browsing(safari,firefox,chrome) in desktop/laptop, that left/right paddles are visible while hovering over those cards. Inside those cards all the link/hyperlink are working fine in desktop/laptop
I am using @mouseover to show those paddles to scroll those cards. In ipad(touch devices), that problem occurs. Because hover effect is not working in touch devices.
Problem
- Those paddles are visible only after first click because hovering is not working for touch devices.
So, i want to disable the hover for touch devices and show the paddles on first rendering. I have checked media queries but it is not working. I am not using jquery. So, how can i show those paddles on initial loading for touch device using vue js.

...ANSWER
Answered 2020-Nov-19 at 10:07Unfortunately no perfect solution to this problem yet exists, and is unlikely to exists in the future. “The Web is meant to be accessible to everyone, regardless of which browser or device they're using.” This implies all content should be visible, and serving different content based on device type is frowned upon by the W3C WAI
However there is a difference between changing the way content appears vs. completely hiding content from users if they’re viewing on different devices. Your scenario falls into the first category, which in my opinion is fine.
Touchscreen devices - smartphone or tablet - cannot support hover events. Rendering the page differently depending on which user agent (device) your site is viewed in is possible, and you have a couple of options. However in general, using the user agent to detect the browser looks simple, but doing it well is, in fact, a very hard problem. Of the two options detailed below, if I had to, I’d go for option 2.
- Detect the user agent using javascript. NOT recommended— read more about the issues here.

QUESTION
I've got some sequences of varying length (auch as textual data encoded into numerical data). To fit them into a tensor, they are right-padded to a fixed width using zeros. For example:
...ANSWER
Answered 2020-May-11 at 16:02One solution would be to count the number of zeros and subtract it from the width of the tensor, but Tensorflow already has a function for counting non-zero values anyhow: tf.math.count_nonzero
.
Thus the solution is as simple as the following one liner:
