kandi X-RAY | coral Summary
Coral is a library for analyzing, processing, and rewriting views defined in the Hive Metastore, and sharing them across multiple execution engines. It performs SQL translations to enable views expressed in HiveQL (and potentially other languages) to be accessible in engines such as Trino (formerly PrestoSQL), Apache Spark, and Apache Pig. Coral not only translates view definitions between different SQL/non-SQL dialects, but also rewrites expressions to produce semantically equivalent ones, taking into account the semantics of the target language or engine. For example, it automatically composes new built-in expressions that are equivalent to each built-in expression in the source view definition. Additionally, it integrates with Transport UDFs to enable translating and executing user-defined functions (UDFs) across Hive, Trino, Spark, and Pig. Coral is under active development. Currently, we are looking into expanding the set of input view language APIs beyond HiveQL, and implementing query rewrite algorithms for data governance and query optimization.

QUESTION
I'm following this great solution to make a slider https://stackoverflow.com/a/70340585/18736427
It uses a good technique where once the slide reaches the first/last slide, it will insert the first/last slide respectively into the first/last place to make a loop effect.
However, this effect is instant...When you click next once it reaches the last slide, the first slide will always immediately be inserted which causes a weird animation sight.
You can run the code snippet to have an idea, the animation looks good before 5, but it will be weird after it.
I've tried the setTimeout method but it looks even weird because it just flies over to the right side every time when you click the next button.
ANSWER
Answered 2022-Apr-14 at 11:53When you move to the next slide you check if you're at the last one and move the first slide back to the right. But because you always show part of the next image you're actually too late at that point: you need to check for the 'one before last' slide. This will give you time to move the next slide into place. Same in the other direction.
You're also doing the same check multiple times (you check if you need to call readyNextSlide, but inside that function you're doing the same check again. So I moved readyNextSlide into the goToSlide function for simplicity.
The below code isn't perfect (for example, it doesn't show slide 6 at the start because it is moved to the back (you should be able to fix that by starting at slide #2) and clicking very quickly will make the slides disappear for a bit (fixable by adding some sort of blocking to clicking until the movement is done, or by using the slide positions instead of just the index in code) but it should help.
See the changes to readyNextSlide which now moves the slides 220% instead of 110%, and is called when you're at the one before last or one before first slide:
QUESTION
I'm fairly new to HTML and still learning and now I'm stuck with something:
I finished making an image carousel and I cannot add a second container under the carousel (its own section). The second container is hiding behind the first one.
...ANSWER
Answered 2022-Apr-08 at 23:02I think I could fix your code and achieve what you are looking for, after I have fixed the indentation in your example.
Indenting your code is importantIndentation of elements is needed to understand what's going on. Maybe the site screwed up your indentation. If not, try to indent any nested elements properly in the future. Learn more on why indentation is important.
What I have done- I have removed some extra closing tags, for example
tag and sometags. - I have changed the absolute positioned elements h1 and carousel to relatively positioned elements to let your layout "flow".
Learn more on when absolute positioned elements are useful. I have exchanged their fixed positioning with margin (top/rightbottom/left/) - I love this "trouble" mnemonic :)
QUESTION
When "position: fixed" hits "class=LimitPoint", I want it to stop and not move.
But the "position: fixed" content goes past "LimitPoint" to "bottom" and then disappears..
Is it possible to make "position: fixed" stop on "LimitPoint" like in the attached image??
If you stop at the "LimitPoint" and then scroll up again, I want it to move with it.
Why doesn't it stop at "LimitPoint"?
Help..!
+) It is very convenient to use "position: sticky", but only 5 types of static, relative, absolute, fixed, inherit are available for the homepage to which this code is applied. It is impossible to use "sticky", so I am inevitably trying to apply it with a script..TT
※I used a translator because I couldn't speak English. That is why my words may not be natural. Please understand.

QUESTION
I have a page where I can choose a user theme color that is used as colors in my app. I have it set up so a modal bottom sheet pops up with the color options and then sets it using Provider so when the navigation is popped the new color can be seen on MyView.
ProblemWhen the user makes a change BUT hits the close button I essentially want to revert all changes made, so to try and tackle this I have a variable called loggedInUser which I initialise in my init State function and I keep out of the build method. So its set once and that's it. The plan is that if the user hits the close button I use Provider to set the details back to the data in loggedInUser (which shoulldn't have the updated color choices).
This does not happen and loggedInUser though not reinitialised has the new colors I chose.

QUESTION
look at this simple example:
...ANSWER
Answered 2022-Mar-08 at 18:09The math works like this...
Step 1
The first div is 50% of 300px, so 150px. The second and third divs are 0px. This leaves a remainder of 150px.
Step 2
Since each div has an equal flex-grow property, the remaining 150px will be divided equally between them, so 50px each.
The first div then becomes 150px + 50px = 200px, and the second and third become 0px + 50px = 50px.
This is based on the concept of positive and negative free space which is used to determin flex item sizes.
QUESTION
I am fairly new to HTML in the past month. I cannot for the life of me, figure out how to change the second image on hover to be a different image when the mouse hovers over it. I know some of the code probably looks dumb with how I tried to guess how I could possibly alter the second hover image. But I am quite confused. If anyone could help that would be great. The only progress I made so far is finally getting them perfectly aligned the way I would want them in the center and also the smooth transition to the hover. All that is left is being stumped on how to change the image to a different one when you hover over the second image. I do not want both hover images to be the same.

How to change the second image on hover to be a different image when the mouse hovers over it?
ANSWER
The approach of this question is to change an image when the user hovering the mouse over it. This task can be simply done by using the CSS background-image property in combination with the :hover pseudo-class to replace or change the image on mouseover.
