49 | Probability distribution of patterns and entropy calculation : As per the source code below, to calculate the pattern distribution, it uses _possible_words_ to generate the distribution. Instead, shouldn't we use _allowed_words_ for this, since any of the allowed words can be generating a given pattern.
ie: the function call should be get_pattern_matrix(allowed_words, allowed_words) ??
```
def get_pattern_distributions(allowed_words, possible_words, weights):
"""
For each possible guess in allowed_words, this finds the probability
distribution across all of the 3^5 wordle patterns you could see, assuming
the possible answers are in possible_words with associated probabilities
in weights.
It considers the pattern hash grid between the two lists of words, and uses
that to bucket together words from possible_words which would produce
the same pattern, adding together their corresponding probabilities.

36 | Creating one folder per video to avoid broken links ? : Taking as an example the last video about Worlde : originally, the link in the youtube video's description was [this one](https://github.com/3b1b/videos/blob/master/_2022/wordle.py). It has since been updated to [that one](https://github.com/3b1b/videos/tree/master/_2022/wordle) in the description, but someone who would have saved the link somewhere else would face a 404 by trying to access it. For instance, on Grant's website the github link to the source code is still [the old one](https://www.3blue1brown.com/lessons/wordle) (broken).
To avoid such situations where a video's code switches from a standalone file to a folder of files (refactor, more details, adding data, ...), maybe it could be a good idea to create a dedicated folder for each video, whatever how many files it contains.
I don't know how often it happens, maybe this is too occasional to be a matter. Plus it is not too hard to fix the link when you have the wrong one (unless there are hundreds of videos in the _YYYY/ folder)

35 | Problem with handling duplicates with the current New York Times implementation : With Wordle moved to https://www.nytimes.com/games/wordle/index.html, it seems to have changed how duplicates are handled.
For example for puzzle 237, after
crane (yybby)
recur (bygyg). (Before the migration, the color pattern was "yygyg" so it now count the second "R" as not existing instead of misplaced for the answer word "ulcer".
I tried both fixes for handling duplicates but neither seems to have fixed it.
The current wordle.py generates the following error:

23 | generate_pattern_grid overcounts multiples of a correct letter : If a "guess" contains a letter more than once, and that letter appears in the "answer", then it counts that letter however many times it exists in the guess, regardless of how many times it appears in the answer.
Assume the guess is `ayyyy` and the answer is `zazzz`. We should expect to get 🟨⬛⬛⬛⬛. If we run that through generate_pattern_grid, we get:
```
>>> generate_pattern_grid(('ayyyy','zazzz'),('ayyyy','zazzz'))
array([[242, 1],
[ 3, 242]], dtype=uint8)
```
Our expected result must be one of those values.
242<sub>10</sub> == 11111<sub>3</sub>
1<sub>10</sub> == 00001<sub>3</sub>
3<sub>10</sub> == 00010<sub>3</sub>
It appears that the digit-endianness here is opposite "normal" usage. If the assumed guess and answer were swapped, then the result would be ⬛🟨⬛⬛⬛, and that seems to match with 00010, but let's verify quickly that we've got it the right way around:
```
>>> generate_pattern_grid(('ayyyy',),('zazzz',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('zzazz',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('zzzaz',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('zzzza',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('azzzz',))
array([[2]], dtype=uint8)
```
That looks right. The first list is the guesses, and the second list is the answers.
Okay, now let's guess `aaaaa` with the answer being `zazzz`. We should expect that answer to be ⬛🟩⬛⬛⬛, or 00020<sub>3</sub>, or 6<sub>10</sub>. Let's see what the function says:
```
>>> generate_pattern_grid(('aaaaa',),('zazzz',))
array([[124]], dtype=uint8)
```
124<sub>10</sub>, huh? That's 11121<sub>3</sub>, or 🟨🟩🟨🟨🟨.
It appears that if a letter in the guess matches a letter in the answer, it gets to be yellow, no matter if it's been used before or not. Let's try something a little more subtle:
```
>>> generate_pattern_grid(('aayyy',),('zzzza',))
array([[4]], dtype=uint8)
```
4<sub>10</sub> == 00011<sub>3</sub> == 🟨🟨⬛⬛⬛, but it should be either 🟨⬛⬛⬛⬛ or ⬛🟨⬛⬛⬛.
Now lets try it with real words:
```
>>> generate_pattern_grid(('geese',),('camel',))
array([[93]], dtype=uint8)
```
93<sub>10</sub> == 10110<sub>3</sub> = ⬛🟨🟨⬛🟨, and it should only have one 🟨.
The problem seems to be here:

4 | Remove pyc blobs and DS_Store from history : Blocked by #3
Currently, cloning the repo can be quite slow. This is probably because of the Python bytecode blobs that were originally added (but later removed). As these are still in the commit history, the repo is still bloated. Using something like [BFG](https://rtyley.github.io/bfg-repo-cleaner/) you could remove all the remnants of both the `*.pyc` and the `.DS_Store` files. As this repo is unlikely to get large code-based external PRs, rewriting history shouldn't have an effect on others. Note that BFG doesn't clean the HEAD commit but all commits before it so there would need to be a non-ignored-removing commit before using it.
Example:
```bash
git clone --mirror https://github.com/3b1b/videos.git
bfg --delete-files '{.DS_Store,*.pyc}' videos.git
cd videos.git
git reflog expire --expire=now --all
git gc --prune=now --aggressive
git push --force
```
After doing this it is recommended to delete your other (previous) clones and run `git clone` again. | [

Instead, shouldn't we use _allowed_words_ for this, since any of the allowed words can be generating a given pattern.
ie: the function call should be get_pattern_matrix(allowed_words, allowed_words) ??

36 | Creating one folder per video to avoid broken links ? : Taking as an example the last video about Worlde : originally, the link in the youtube video's description was [this one](https://github.com/3b1b/videos/blob/master/_2022/wordle.py). It has since been updated to [that one](https://github.com/3b1b/videos/tree/master/_2022/wordle) in the description, but someone who would have saved the link somewhere else would face a 404 by trying to access it. For instance, on Grant's website the github link to the source code is still [the old one](https://www.3blue1brown.com/lessons/wordle) (broken).
To avoid such situations where a video's code switches from a standalone file to a folder of files (refactor, more details, adding data, ...), maybe it could be a good idea to create a dedicated folder for each video, whatever how many files it contains.
I don't know how often it happens, maybe this is too occasional to be a matter. Plus it is not too hard to fix the link when you have the wrong one (unless there are hundreds of videos in the _YYYY/ folder)

35 | Problem with handling duplicates with the current New York Times implementation : With Wordle moved to https://www.nytimes.com/games/wordle/index.html, it seems to have changed how duplicates are handled.
For example for puzzle 237, after
crane (yybby)
recur (bygyg). (Before the migration, the color pattern was "yygyg" so it now count the second "R" as not existing instead of misplaced for the answer word "ulcer".
I tried both fixes for handling duplicates but neither seems to have fixed it.

23 | generate_pattern_grid overcounts multiples of a correct letter : If a "guess" contains a letter more than once, and that letter appears in the "answer", then it counts that letter however many times it exists in the guess, regardless of how many times it appears in the answer.
Assume the guess is `ayyyy` and the answer is `zazzz`. We should expect to get 🟨⬛⬛⬛⬛. If we run that through generate_pattern_grid, we get:
```
>>> generate_pattern_grid(('ayyyy','zazzz'),('ayyyy','zazzz'))
array([[242, 1],
[ 3, 242]], dtype=uint8)
```
Our expected result must be one of those values.
242<sub>10</sub> == 11111<sub>3</sub>
1<sub>10</sub> == 00001<sub>3</sub>
3<sub>10</sub> == 00010<sub>3</sub>
It appears that the digit-endianness here is opposite "normal" usage. If the assumed guess and answer were swapped, then the result would be ⬛🟨⬛⬛⬛, and that seems to match with 00010, but let's verify quickly that we've got it the right way around:
```
>>> generate_pattern_grid(('ayyyy',),('zazzz',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('zzazz',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('zzzaz',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('zzzza',))
array([[1]], dtype=uint8)
>>> generate_pattern_grid(('ayyyy',),('azzzz',))
array([[2]], dtype=uint8)
```
That looks right. The first list is the guesses, and the second list is the answers.
Okay, now let's guess `aaaaa` with the answer being `zazzz`. We should expect that answer to be ⬛🟩⬛⬛⬛, or 00020<sub>3</sub>, or 6<sub>10</sub>. Let's see what the function says:
```
>>> generate_pattern_grid(('aaaaa',),('zazzz',))
array([[124]], dtype=uint8)
```
124<sub>10</sub>, huh? That's 11121<sub>3</sub>, or 🟨🟩🟨🟨🟨.
It appears that if a letter in the guess matches a letter in the answer, it gets to be yellow, no matter if it's been used before or not. Let's try something a little more subtle:
```
>>> generate_pattern_grid(('aayyy',),('zzzza',))
array([[4]], dtype=uint8)
```
4<sub>10</sub> == 00011<sub>3</sub> == 🟨🟨⬛⬛⬛, but it should be either 🟨⬛⬛⬛⬛ or ⬛🟨⬛⬛⬛.
Now lets try it with real words:
```
>>> generate_pattern_grid(('geese',),('camel',))
array([[93]], dtype=uint8)
```
93<sub>10</sub> == 10110<sub>3</sub> = ⬛🟨🟨⬛🟨, and it should only have one 🟨.
The problem seems to be here:

13 | How to compile _2016/eola? : I'd like to run scenes from EoLA. I understood that EoLA was a bit too old to run with manimgl 1.2.0. So I checked out this particular commit:
commit 73ff0af63de1cd382e1c8552aa1c97d07e4e8744
Author: Grant Sanderson <grantsanderson7@gmail.com>
Date: Sat Sep 24 22:46:17 2016 -0700
End of EoLA
to get to the state when EoLA was completed.
But it seems to me that codes under _2016/eola have been updated for newer versions of manim even though they are not fully updated yet so that they can be run without changing anything. Therefore they can not be run with the above commit of manim either.
Would it be possible to get the version of EoLA source code as it exactly was when the above particular commit was made? | [
"At that point, all the video code was in the manim repo, so you'd want to look for the version that existed there."

9 | could you make more lesson about that 2d to 3d and 2d to 3d through camera : Thank you for all intuition and beautiful lessons, but some others , such as 2d to 3d and 2d to 3d through camera, intrsic matrix, extern matrix, how to know 2d plane project camera etc, I don't understand.
could you make lessons more about it.

8 | Editing one graph edits all : Not sure if this is the best place to mention this. The interactive Fourier transform page has an oddity: if you edit the frequency selection in one interactive graph, all of them change the red lines. The white dot that tracks the mouse still uses the specific graph's frequency set, but it's running across an incorrect red line that belongs on a different graph. | [

docs/source/getting_started/whatsnew.rst:29: - Removed all camera classes except ``Camera`` (``MappingCamera``, ``MovingCamera``, ``MultiCamera``) and all functions in ``ThreeDCamera``
docs/source/getting_started/whatsnew.rst:123: - Removed all functions of ``GraphScene`` (moved to ``once_useful_constructs``), ``MovingCameraScene``, ``ReconfigurableScene``, ``SceneFromVideo``, ``ZoomedScene``, and ``ThreeDScene``. Because these can basically be achieved by adjusting ``CameraFrame`` (``self.camera.frame``)

4 | Remove pyc blobs and DS_Store from history : Blocked by #3
Currently, cloning the repo can be quite slow. This is probably because of the Python bytecode blobs that were originally added (but later removed). As these are still in the commit history, the repo is still bloated. Using something like [BFG](https://rtyley.github.io/bfg-repo-cleaner/) you could remove all the remnants of both the `*.pyc` and the `.DS_Store` files. As this repo is unlikely to get large code-based external PRs, rewriting history shouldn't have an effect on others. Note that BFG doesn't clean the HEAD commit but all commits before it so there would need to be a non-ignored-removing commit before using it.
Example:
```bash
git clone --mirror https://github.com/3b1b/videos.git
bfg --delete-files '{.DS_Store,*.pyc}' videos.git
cd videos.git
git reflog expire --expire=now --all
git gc --prune=now --aggressive
git push --force
```
After doing this it is recommended to delete your other (previous) clones and run `git clone` again. | [
