kandi X-RAY | shudder Summary
Shudder is a service for facilitating graceful shutdowns in AWS autoscaling groups. It works by making use of Lifecycle Hooks. You give your autoscaling group a lifecycle hook that publishes to an SNS topic that you configure in shudder. When shudder starts up, it will create an SQS queue for the instance it is running on and subscribe it to the SNS topic. It polls for new messages and waits for one that is a termination command for this instance. It can then send a GET request to a configured endpoint telling it to shut down gracefully, or execute commands. It can also detect when a spot instance has been scheduled for termination, using the instance termination notice available in instance metadata. The same configured endpoint will be hit if a scheduled termination of a spot instance is detected.

QUESTION
So I need some line of code to make it so that if one of the four words is entered, it jumps back to a certain line. This is for a text-based rpg game.

I have two dataframes, the one contains Reviews for cars and the second one contains the car make and car model. What I would like to do is use the car model df_brand['name']
to be used to lookup every word in the Review sentence df['Review']
and remove matching words. I would like to remove all the words that contain car brands in them.

Answered 2021-Dec-07 at 20:57Your problem wasn't quite condensed enough to reproduce, or to see the desired output, but your basic approach is fine. You may run into issues with misspellings, in which case maybe use an edit distance with a threshold for determining whether to take out the stopword. Here's my version of your code that seems to do fine

QUESTION
I have some view that consists from one stackview. Every n
second I should update this view with data from server. When the new data come, I clean stackView (with method removeFromSuperView of its children) and add arrangedSubviews again to update UI. Sometimes, server sends the same data as old data. But doing this update operation, my view is kinda shuddering. Its kinda dragging and shuddering every time I clean and add views to my stackview. Of course, I can only update my UI if oldData != newData. But this competition is difficult and hard to find correctly. So, how to update stackview with new data without shuddering and blinking?
Here is my code:
...ANSWER
Answered 2021-Feb-26 at 17:06Instead of removing / re-adding views to the stack view...
- only add new views if there are more Items than current arranged subviews
- set the data -
configure()
- each arranged subview - hide existing arranged subviews if there are more than needed
For example:
QUESTION
I have a UIViewController
that contains a UICollectionView
and a UIView
which acts as the view header.
I would like to collapse the header when the view scrolls. I am currently doing this by capturing the top anchor for my header in a variable and using scrollViewDidScroll
to set the constant
for this value.
ANSWER
Answered 2020-Aug-30 at 14:01Seems like UIScrollView
has a bounces
property which is set to true
by default.
From the documentation:
If the value of this property is true, the scroll view bounces when it encounters a boundary of the content. Bouncing visually indicates that scrolling has reached an edge of the content. If the value is false, scrolling stops immediately at the content boundary without bouncing. The default value is true.
This explains that shuddering behaviour where the animation is being applied whilst being corrected by your top constraint while hitting the boundary.
I set collectionView.bounces = false
in viewDidLoad
and it works like intended now.
QUESTION
When setting @keyframes
using CSS transform
in Safari (desktop and iOS) with just an end frame, and then updating the starting transform
position programmatically (inline via JS), Safari appears to continue to execute the animation from the initial position (i.e. using the initial transform value in the stylesheet) - not using the inline style.
In short, Safari keyframe animations don't appear to update to reflect any changes to inline styles that are added programmatically
The below snippet (reduced test case) works in both Firefox and Chrome, but Safari just animates to the position of 0. My question is whether or not there is a workaround for this? Is this an intended representation of the spec by Apple, and should programmatic inline styles be ignored for keyframe animations? I can't imagine that they should.
I have tried cloning and replacing the element, to no avail. I also tested with the inline style being included onLoad, and this did work in Safari, so the bug seems to only be when the style is added programmatically.
I appreciate I can animate entirely using JS and requestAnimationFrame
, which is my fallback solution if the above fails. (Likewise, a great solution is to use the Web Animation API, which seems exactly made for this purpose. But support for that is patchy, so a no-go for now). What I am really interested in is a solution to the above bug, rather than alternative suggestions.
(As an aside, the tag still works as a cross-browser solution... *shudder*)

ANSWER
Answered 2020-Jul-17 at 14:32After perusing Lenz' "Parsing with Perl 6 Regexes and Grammars" (Apress, 2017), I realized the "regex" machinery (based on backtracking) might actually be a lot more capable than officially admitted, as a regex can call another, and nowhere do I see a prohibition on recursive calls.
Before digging in, a bit of context free grammars: A way to describing nested braces (and nothing else) is with the grammar:
S -> { S } S |
I.e., nested braces are either an opening brace, nested braces, a closing brace, more nested braces; or nothing whatsoever. This translates more or less directly to Raku (there is no empty regex, fake it by making the construction optional):

Install shudder
You can use shudder like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
