flips | feature flip library which provides various annotations | Access Management library

I've been learning react over the last few days and for the most part it makes sense, however there is one thing that is stumping me.

If I have

• A Parent element with some state variables and a callback method
• A child element that takes a callback method as a prop
• The callback method relies on some piece of state that is in the parent element
• I don't want to re-create the view object every time any state changes

Every time I try to do this, it seems like the child element is calling some older version of the parent element (presumably the instance of the parent that actually created the child) instead of the current version.

I'm getting the feeling that what I want is just wrong on a fundamental level and isnt The React Way

The reason that I am trying to do this is that my main parent contains 17 divs, each of which represent a key on a musical instrument, and each of which contains at least 20-30 divs. The lowest div (of which there are at least a few hundred) has an onClick event that I want to modify the functionality of based on whether modifier keys are held down (shift, control etc).

Currently I have Raised the state of the shiftPressed to be on the single parent element then passed down the value of that into each child through props, however re-rendering hundreds of divs whenever a user pushes shift takes quite a while.

I've made a code sandbox to show the current problem sandbox

I came across a problem that I can't solve. Whenever I move my character if it's near the edge of the map it goes through the tilemaps collider and goes out of the map. Here's the screenshot I took:

This is normal: link text

This is when the bug occurs: bug

Here's the code I'm using to move and flip the character:

I need to create a python program that will use various functions to simulate flipping a coin 100 times and finding the largest streak of "H"'s out of 10,000 tries. I am stuck on how to finish the def main() function, specifically the counter. I also don't know if my program is calculating the streaks correctly.

def flipCoin() - returns 'H' or 'T' with the same probability as a coin.

def simulate(numFlips) - simulates flipping a coin numFlips(100) times. This function returns a list of length numFlips containing H's and T's.

def countStreak(flips_list) - iterates through the flips list passed to it and counts streaks of 'H's and returns the largest streak it finds. Keep track of the current number of heads and the current largest streak of heads in two separate variables. As you iterate through the list, keep track of the current number of heads you've seen in a row. If you see a tail, check if the current streak of heads is larger than your current longest streak. If so, save the current streak. Then reset your heads counter.

In the main function, write a testing loop that simulates the process 10000 times. Keep track of the current largest streak of heads and display this result after the test loop completes.

I am building a Django template which will use jsrender in order to build out dynamic Javascript templates for html code.

However, I find that when I put a Jsrender template in my code, Django flips out because Django parses anything between {{ and }} as a variable, and Jsrender uses this for its own variables. For instance, a template in Jsrender might look like:

I noticed that in cppreference/bitset, bitset is not mentioned to be inherited from _ Base_bitset , including the following header file.

Does the cppreference estimate omit this inheritance relationship?

I have taken code for two projects. One being the code for creating a cube and another is the code for creating a pyramid. I am now trying to render both of the objects in OpenGL which I have done the problem is the objects are attached to one another. I have added some code heading towards rendering them separately, however I am now stuck where my cube is only showing 3 of the triangles used to create it and the whole pyramid shows. Yet the objects are still attached to one another. Any help or guidance?

I'm refactoring some old code for an alert widget and am abstracting it into its own component that uses DOM portals and conditional rendering. I want to keep as much of the work inside of this component as I possibly can, so ideally I'd love to be able to expose the Alert component itself as well as a function defined inside of that component triggers the render state and style animations so that no outside state management is required. Something like this is what I'm looking to do:

I have a page with a search field. If accessed with a query parameter (e.g. ?word=cat) the page should load with results present and the search field filled. If a search is done the results and the query parameters (browser history) should update.

The only way I found to update query parameters is goto, so my attempt is:

I'm trying to make a basic coin flipping simulator. And ask the user for their name and greet them. Then ask if they want to play the game. But when they enter something other than "Y", it gives this error message: UnboundLocalError: local variable 'time_flip' referenced before assignment how can I fix that and instead it prints a goodbye message. And ask them again if they want to keep playing.
