Que necesidad de filmar encima tipa pesada👎 ,ellos unos genios 👏

so exaggerated

to set up a lean project do this: ```bash # -- Setup our lean_src_proj Lean 4 project for the first time (ref: leanprover-community.github.io/install/project.html#lean-projects) # - Go to a folder where you want to create a Lean 4 project (e.g., the root of this `learning_lean` git repo) cd $HOME/learning_lean # - Then create the Lean 4 project with the following options (note: usually a Lean 4 project's path **is** the same as the root of the github repo, but not for us) # Option 1: setting up the Lean 4 project at `lean_src_proj`` for the first time (& installing Mathlib) lake +leanprover/lean4:nightly-2023-02-04 new lean_src_proj math # Option 2: set up Lean 4 project at `lean_src_proj` if the path `lean_src_proj` already exists but Mathlib has not been installed (e.g., after git cloning the root git repo `learning_lean`) cd lean_src_proj lake update lake exe cache get # if you get an error message saying lake is an unknown command and you have not logged in since you installed Lean, then you may need to first type # source ~/.profile or source ~/.bash_profile # -- Go inside Lean 4 project dir and set it up # cd to the Lean 4 project folder cd lean_src_proj # Update the dependencies and fetch the latest versions specified in the lakefile (in your Lean 4 project's at `lean_src_proj`) lake update # Retrieve the cached files to speed up subsequent builds and ensure the latest cached versions are used lake exe cache get # -- The Lean code *.lean for your Lean 4 project (located at `learning_lean/lean_src_proj`) should be at learning_lean/lean_src/MyProject/ or a subfolder thereof. # - Go to root of Lean 4 project in this github repo cd $HOME/learning_lean/learn_src_proj # Create 1st folder with the Lean 4 src code will like for our Lean 4 project (at the path `learning_lean/learn_src_proj`) mkdir MyLean4CodeFolder1 cd MyLean4CodeFolder1 echo 'import Mathlib.Topology.Basic #check TopologicalSpace' > Test.lean # Create 2nd folder with the Lean 4 src code will like for our Lean 4 project (at the path `learning_lean/learn_src_proj`) mkdir MyLean4CodeFolder2 cd MyLean4CodeFolder2 echo 'import Mathlib.Topology.Basic #check TopologicalSpace' > Test.lean # Create 3rd folder with Lean 4 code cd $HOME/learning_lean/lean_src_proj mkdir AesopExample cd AesopExample echo -e 'import Aesop example : α → α := by aesop' > AesopExample/aesop_example.lean # Add Aesop dependency to lakefile.lean if not already present if ! grep -q 'require aesop from git "github.com/JLimperg/aesop"' lakefile.lean; then echo 'require aesop from git "github.com/JLimperg/aesop"' >> lakefile.lean echo "Added Aesop dependency to lakefile.lean." else echo "Aesop dependency already exists in lakefile.lean." fi # Recompile Lean 4 Project at `learning_lean/lean_src_proj` cd $HOME/learning_lean/lean_src_proj lake update lake exe cache get # lake build # ...etc... # Note: confusingly, the official tutorial for creating a Lean 4 project (which for them is usually the root of the git repo) has a folder named `my_project/MyProject/` # (or a subfolder thereof), for details see: leanprover-community.github.io/install/project.html # but for us our Lean 4 project is not the root but instead is at `learning_lean/lean_src_proj` with folder with *.lean files in the subfolders there e.g., # `MyLean4CodeFolder1`, `MyLean4CodeFolder2`, ...etc... ```

cool

I made some important changes to the Readme and install.sh script: github.com/brando90/learning_lean?tab=readme-ov-file#main-concepts Main new concepts to remember are the following: Lean 4 Project := Usually a Lean 4 project is the root of the github repo. It usually has the lakefile.lean, lean-toolchain files, .lake, Folder_With_Lean_Code, etc. In our case the root of the repo is not the Lean 4 project and instead with have a seperate folder for the Lean 4 source code (that will be the root of the Lean 4 project) at learning_lean/lean_src_proj. Github project root := For pure Lean 4 Projects it's the same as the root of the Lean 4 project root. For that's not the case and there might be an additional py_src too.

I will add more nuance to the statement I made at 1:09:00 if you do a proof by simp, since it has **more** automation than rewrite, it can make the proof more **robust** e.g., if the theory you're writing changes or if Lean itself changes -- since it has more automation. Which can help because there is less refactoring/fixing code (less "proof repair"). So proofs by simp can be better than proofs with rewrites.

Greatness 🎉😅😊😂❤x0x0

didn't know deriving repr thing, nice

This is very helpful. Thanks a lot :)

Types vs Sets: twitter.com/BrandoHablando/status/1763717742178578444 someone perhaps can explain in simple terms?

Emergent abilities are bullshit. Bad measurement. Worse science.

Very nicely done.

☠It looked like people found some secret sauce but it turned out to be a whole lot of nothing. (Still impressive what they can do regardless)

Hey, was there any response to Jason Wei's "Common Arguements agsint Emergent Abilities", I just read it and I thought it had really good points and I wanted to know more about this! Please let me know!!

Hey there, thanks for the research and presentation! Have you or anyone affiliated gotten any feedback from, let's say OAi researchers :)?

Лариса лучшая

La bachata dominicana es la mejor y para mí es un orgullo soy de Veracruz pero yo no cambio el estilo dominicano la otra forma de bailar la ago a un lado prefiero la verdadera música sabrosa

great event last night (Sun 12/10). Is there a name of the version of Manuel Turizo's "La Bachata" that you used during yesterday's lesson?

lindo amei

. Хочется смотреть снова и снова. Таких больше нет. Энергетика пробивает экран.

❤❤❤

is this practice at Stanford university?

Hell yeah us fluffy guys can move 😂😅

❤❤❤

❤❤❤

Que Cursi como bailas 😮

Самая любимая пара, самая прекрасная партнерша на мой взгляд! 😍

Очень красиво. Любовь и чувственность зашкаливают. Спасибо.👍✌️🔥🎉💖👏👏👏👏💕💕💕💕💕💕

Ребята вы лучшие.👍✌️🔥🎉💖👏👏👏💕💕💕💕💕

Wow, I just came across this video after years and brought back so many beautiful memories. Thank you for recording and posting so I can come back to watch every once in awhile. This was such an impactful moment for me, so thank you :)

this guy moves like a log

Этот парень двигается как бревно

В этой паре большая роль отведена Ларисе, а вот во всех почти предыдущих и последующих Рик. Очень жаль, что вышло так грустно. Но каждый выбирает свою дорогу сам. На последнем выступлении Лари в Мексике были, кстати сказать, всё его друзья. Это о чём-то говорит. А вообщеРие молодец, что дал Лари возможность появиться самой и показать всём на что она, Лари, способна сама, как артистка и как личность. Пусть и Рику улыбнётся удача.
