# [Jupyter Notebooks](http://jupyter.org/) :notebook: by [Naereen @ GitHub](https://naereen.github.io/)

This repository hosts *a lot of* [Jupyter Notebooks](http://jupyter.org/), covering various subjects.
Everything is open-sourced under [the MIT License](https://lbesson.mit-license.org/), you can use any of these notebooks for your own teaching activities if you want. Please [open an issue](https://github.com/Naereen/notebooks/issues/new), or [ask me anything](https://github.com/Naereen/ama) or [drop an email](https://besson.link/callme.en.html) if you have any questions, suggestions, or more.

*Which languages?* Half of the notebooks here are in :gb: English, and the other half in :fr: French (surtout pour *l'agrégation de mathématiques option informatique*, dans ce dossier [`agreg/`](agreg/)), and most use [the Python language](https://www.Python.org/), or [OCaml](https://OCaml.org), and a few notebooks use other languages like Julia, Rust, Java or even Bash, C and Octave!

## How to read or use these notebooks?
You can view this repository on [nbviewer](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/) to read notebooks statically, or read them directly from GitHub.

You can also launch an interactive environment to play with the code by yourself, using one of these platforms:
- MyBinder should work fine even for OCaml notebooks, but it's quite slow. It's fully open-source, and reliable: [![MyBinder v2](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/Naereen/notebooks/master)
- Google Colab should work only for Python notebooks, but it's blazing fast to load. It's not open-source and requires to use Google's servers: [![Google Colab: Launch](https://img.shields.io/badge/Google%20Colab-Launch-blue.svg)](https://colab.research.google.com/github/Naereen/notebooks/blob/master/)

- **New!** In Feb'21, [I have installed](https://github.com/Naereen/Mon-utilisation-de-Basthon/) the amazing [Basthon notebook](https://basthon.fr/about.html) to my website, at <http://notebook.besson.link/>, and you can use it with any of the notebooks available in the repository, for instance <https://besson.link/Basthon/notebook/?from=../../publis/notebooks/Py_Pi_Day_2017.ipynb> for [`Py_Pi_Day_2017.ipynb`](Py_Pi_Day_2017.ipynb), because this folder is synced on my website at <https://besson.link/publis/notebooks/>. Please [open an issue](https://github.com/Naereen/notebooks/issues/new) if this doesn't work!

## My use of notebooks - short story since 2015

- At the beginning (as early as end of 2015!), this repository was only here to host some small experiments, for me to learn how to use [the wonderful Jupyter tools](http://jupyter.org/) correctly. So they were baby notebooks :baby_bottle:... Since then, I did *a lot of experiments*, on all the most important kernels (Python, Julia, but also less standard ones like OCaml, Rust, Java, C, Bash, etc), all the most exciting notebook extensions, and output formats (PDF, script, static HTML, slides, etc). I've kept learning and discovering more [awesomeness of the Jupyter environment](https://github.com/markusschanta/awesome-jupyter), and it never stops to amaze me :sparkles:!
- In the last 5 years (2016-2021), I've used Jupyter notebooks intensively, to teach algorithmics, programming, and (not so theoretical) computer science in general, mainly in :fr: French. I wrote notebooks to teach [introduction to Java in 2020](https://perso.crans.org/besson/teach/INF1_L1_Rennes1_2020-21/), [advanced algorithms using Python in 2019](https://github.com/Naereen/ALGO1-Info1-2019), and a lot for experimenting during [my PhD thesis](https://perso.crans.org/besson/phd/).
- :fr: J'ai aussi corrigé *tous* les textes d'annales de modélisation, en option informatique, pour le concours national de l'agrégation de maths, en utilisant OCaml ou des fois Python ! Ce sont les seuls corrigés de ce type disponibles sur tous les Internets (j'ai cherché partout !), et ils sont dans ce dossier : [`agreg/`](agreg/). [Je compte]() déplacer ça dans un dossier à part, et bien les nettoyer et mettre à jour, en 2021.
- I love the Jupyter environment, from the old [IPython command line](https://ipython.org/) to the recent [awesome](https://github.com/mauhai/awesome-jupyterlab) [Jupyter Lab](https://github.com/jupyterlab/jupyterlab). If you want to discover amazing things, check out: [RISE for live slides in a notebook](https://rise.readthedocs.io/), [lolviz](https://github.com/parrt/lolviz/) and [rcviz](https://github.com/DamnedFacts/rcviz) and [tutormagic](https://github.com/kikocorreoso/tutormagic/) for nice data structures visualizations in a notebook.

- In the future, **I plan to mostly teach using Jupyter notebooks**, using either the regular Python kernel, the [OCaml-jupyter](https://github.com/akabe/ocaml-jupyter/) kernel for [OCaml](https://ocaml.org) (and also [IJava](https://github.com/SpencerPark/IJava) for Java, [this one for C](https://github.com/brendan-rius/jupyter-c-kernel), and more if needed). RISE slides embed a chalk-board mode, more limited in comparison to the amazing [TableauNoir](https://tableaunoir.github.io/).

## A partial list of notebooks in this repository

I'm trying to maintain here a list of the notebooks stored in this repository, inspired by the amazing [pytudes](https://github.com/norvig/pytudes) by [Peter Norvig](https://github.com/norvig/).
The links open [nbviewer](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/)), and the links ([on GitHub?](https://github.com/Naereen/notebooks/)) open the notebook to be viewed directly in GitHub (it should work for almost all of them).

### :shell: Bash
- The first notebooks I wrote are small tutorials for :shell: `bash` commands (or some of my [command-line scripts](https://bitbucket.org/lbesson/bin/src/master/)), see for example [a tutorial on head and a tail](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Tutorial%20on%20head%20and%20tail%20%28bash%29.ipynb) ([on GitHub?](Tutorial%20on%20head%20and%20tail%20%28bash%29.ipynb)).

### :snake: Python
> I am a passionate user of [the Python programming language](https://www.python.org/).

#### Science
- [This notebook written for the Pi Day 2017](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Py_Pi_Day_2017.ipynb) ([on GitHub?](Py_Pi_Day_2017.ipynb)) demonstrates a dozen of easy algorithms to compute from 10 to 100000 digits of the *number pi*.

- [This notebook implements a simple example of the *simulated annealing* algorithm](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Simulated_annealing_in_Python.ipynb) ([on GitHub?](Simulated_annealing_in_Python.ipynb)) to minimize black-box functions :sunglasses:.

- [This notebook shows a hand-written and clear implementation](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Manual_implementation_of_some_hash_functions.ipynb) ([on GitHub?](Manual_implementation_of_some_hash_functions.ipynb)) of several [Hashing functions](https://docs.python.org/3/library/hashlib.html), like `MD5`, `SHA1`, and all variants of `SHA2` (`SHA256`, `SHA224`, `SHA512`, `SHA384`).

- [This notebook shows a manual implementation](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Short_study_of_the_Lempel-Ziv_complexity.ipynb) ([on GitHub?](Short_study_of_the_Lempel-Ziv_complexity.ipynb)) of the [Lempel-Ziv complexity](https://en.wikipedia.org/wiki/Lempel-Ziv_complexity) in pure Python, and then as optimized Python code, with Cython or Numba. I also wrote a version in [Julia](http://julialang.org) (in the same notebook), and compare the 4 implementations! I then published my code as a Pypy package, see [here on pypi.org](https://pypi.org/project/Lempel-Ziv_Complexity/).

- [This notebook shows a hand-written and clear implementation](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Manual_implementation_of_the_Mersenne_twister_PseudoRandom_Number_Generator__PRNG_.ipynb) ([on GitHub?](Manual_implementation_of_the_Mersenne_twister_PseudoRandom_Number_Generator__PRNG_.ipynb)) of several [Pseudo-Random Number Generators](https://docs.python.org/3/library/random.html), including the famous *Mersenne twister* algorithm, and then uses it to samples from the most famous discrete and continuous distributions, showcasing use of the Inverse-Transform method and Acceptance-Rejection method (cf. Markov Chain Monte-Carlo methods).

- [This notebook implements and compares different Runge-Kutta methods](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Runge-Kutta_methods_for_ODE_integration_in_Python.ipynb) ([on GitHub?](Runge-Kutta_methods_for_ODE_integration_in_Python.ipynb)) for integrating Ordinary Differential Equations in Python. And also [in Julia](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Runge-Kutta_methods_for_ODE_integration_in_Julia.ipynb) ([on GitHub?](Runge-Kutta_methods_for_ODE_integration_in_Julia.ipynb)), and also [in OCaml](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Runge-Kutta_methods_for_ODE_integration_in_OCaml.ipynb) ([on GitHub?](Runge-Kutta_methods_for_ODE_integration_in_OCaml.ipynb)). I wanted to compare the three languages for the same algorithms. Well, obviously, Julia is the fastest and simplest for numerical simulations like this.

- [This short notebook defines and studies the Rényi entropy](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/A_short_study_of_Renyi_entropy.ipynb) ([on GitHub?](A_short_study_of_Renyi_entropy.ipynb)).

- :fr: [Ce notebook présente des approches simples pour générer un dictionnaire des mots français adaptés à l'écriture inclusive](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Ecriture%20inclusive.ipynb), comme beau/belle -> beau·elle, professeur/professeure -> professeur·e, il/elle -> iel/ielle etc ([on GitHub?](Ecriture%20inclusive.ipynb)). [Ici ce trouve le dictionnaire généré (contenant environ 26 000 mots différents)](french_inclusive.txt). ~~Work in progress?~~ (je ne terminerai pas, c'est trop compliqué de faire ça parfaitement)

- :fr: En s'inspirant de [cet article](https://kalebujordan.com/make-your-own-plagiarism-detector-in-python/) (décembre 2020), [j'expérimente dans ce notebook avec scikit-learn pour détecter les similarités et les risques de plagiat dans des projets étudiants écrits en Java](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/My_own_tiny_similarity_and_plagiarism_detector_in_Python_scikit-learn.ipynb) (mais l'approche est indépendante du langage !) ([on GitHub?](My_own_tiny_similarity_and_plagiarism_detector_in_Python_scikit-learn.ipynb))

### Teaching

- :fr: [Ce notebook en français présente les problèmes de bandits multi-bras stochastiques](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Introduction_aux_algorithmes_de_bandit__comme_UCB1_et_Thompson_Sampling.ipynb) ([on GitHub?](Introduction_aux_algorithmes_de_bandit__comme_UCB1_et_Thompson_Sampling.ipynb)) (*multi-armed bandit*, MAB), et les algorithmes dits "de bandits" pour les résoudre (UCB "Upper Confidence Bounds", KL-UCB, Thompson Sampling, Approximated Finite-Horizon Gittins index etc).

#### Experiments with Python
- [This small notebook](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Living_in_a_noisy_world_with_James_Powell_rwatch_module.ipynb) ([on GitHub?](Living_in_a_noisy_world_with_James_Powell_rwatch_module.ipynb)) is a fun experiment, where I tried to use [James Powell (@dutc)](https://GitHub.com/dutc) [rwatch](https://GitHub.com/dutc/rwatch) module to write a Python context manager to add a Gaussian white noise to every numbers inside the context... Something like: `with noise(): x = 10` will produce `x = 10.325` for instance... It fails, but I almost got it, and it works (without breaking the interpreter) for complex numbers. That's already intersting!

- [This notebook](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Floating_point_error_propagation_in_polynomial_multiplication_with_Fast-Fourier_Transform.ipynb) ([on GitHub?](Floating_point_error_propagation_in_polynomial_multiplication_with_Fast-Fourier_Transform.ipynb)) is a small experiment, written quickly, about floating-point error propagation when using a non-naive polynomial multiplication with evaluation-and-interpolation. Sadly, this approach fails!

- [A tiny presentation on how to do time/memory profiling](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Profiling_in_a_Jupyter_notebook.ipynb) ([on GitHub?](Profiling_in_a_Jupyter_notebook.ipynb)) from *inside* the Jupyter notebook interface, with various approaches.

- 🔍 ✨ I first tried the [`lolviz`](https://github.com/parrt/lolviz/) [module in 2017](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Testing_the_lolviz_Python_module.ipynb) ([on GitHub?](Testing_the_lolviz_Python_module.ipynb)), and then again in 2021, to [improve it](https://github.com/parrt/lolviz/issues/27), [with a unified display function that chooses the best one based on the datatype](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Extending_lolviz_with_a_unified_display_function_that_chooses_the_best_one_based_on_the_datatype.ipynb) ([on GitHub?](Extending_lolviz_with_a_unified_display_function_that_chooses_the_best_one_based_on_the_datatype.ipynb)).

### Experiments with Jupyter

### 1.a. View the notebooks statically :memo:
- Either directly in GitHub: [see the list of notebooks](https://github.com/Naereen/notebooks/search?l=jupyter-notebook);
- Or on [nbviewer.jupiter.org](https://nbviewer.jupiter.org/): [list of notebooks](https://nbviewer.jupyter.org/github/Naereen/notebooks/tree/master/).

### 1.b. Play with the notebooks dynamically :boom:
[![MyBinder](http://mybinder.org/badge.svg)](http://mybinder.org/repo/Naereen/notebooks)

Anyone can use the [mybinder.org](http://mybinder.org/) website (by [clicking](http://mybinder.org/repo/Naereen/notebooks) on the icon above) to run the notebook in her/his web-browser.
You can then play with it as long as you like, for instance by modifying the values or experimenting with the code.

You can also launch an interactive environment to play with the code by yourself, using one of these platforms:
- MyBinder should work fine even for OCaml notebooks, but it's quite slow. It's fully open-source, and reliable: [![MyBinder v2](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/Naereen/notebooks/master)
- Google Colab should work only for Python notebooks, but it's blazing fast to load. It's not open-source and requires to use Google's servers: [![Google Colab: Launch](https://img.shields.io/badge/Google%20Colab-Launch-blue.svg)](https://colab.research.google.com/github/Naereen/notebooks/blob/master/)

- **New!** In Feb'21, [I have installed](https://github.com/Naereen/Mon-utilisation-de-Basthon/) the amazing [Basthon notebook](https://basthon.fr/about.html) to my website, at <http://notebook.besson.link/>, and you can use it with any of the notebooks available in the repository, for instance <https://besson.link/Basthon/notebook/?from=../../publis/notebooks/Py_Pi_Day_2017.ipynb> for [`Py_Pi_Day_2017.ipynb`](Py_Pi_Day_2017.ipynb), because this folder is synced on my website at <https://besson.link/publis/notebooks/>. Please [open an issue](https://github.com/Naereen/notebooks/issues/new) if this doesn't work!

> *Note:* Only the Python kernel is supported on the MyBinder interface!

----

## 2. *Requirements to run the notebooks locally*?
All [the requirements](requirements.txt) can be installed with [``pip``](https://pip.readthedocs.io/) and by running a few ``python -m ...`` commands.

> Note: if you use [Python 3](https://docs.python.org/3/) instead of [Python 2](https://docs.python.org/2/), you *might* have to *replace* ``pip`` and ``python`` by ``pip3`` and ``python3`` in the next commands (if both pip and pip3 are installed).

> :warning: I've not updated this section since 2016.

### 2.a. [Jupyter Notebook](http://jupyter.readthedocs.org/en/latest/install.html) and [IPython](http://ipython.org/)

```bash
sudo pip install jupyter ipython
```

It will also install all the dependencies, afterward you should have a ``jupyter-notebook`` command (or a ``jupyter`` command, to be ran as ``jupyter notebook``) available in your ``PATH``:

```bash
$ whereis jupyter-notebook
jupyter-notebook: /usr/local/bin/jupyter-notebook
$ jupyter-notebook --version  # version >= 4 is recommended
4.2.1
```

### 2.b. Other kernels (*optional*):
> They are only needed to run the notebooks written for Bash or Octave (or OCaml):

#### 2.b.1. [GNU Bash kernel](https://github.com/takluyver/bash_kernel)
- You have to have [``bash``](https://en.wikipedia.org/wiki/Bash_(Unix_shell)) installed ([already there](https://tiswww.case.edu/php/chet/bash/bashtop.html) on all Linux distribution, installable with [``brew``](http://brew.sh/) or [``macports``](https://www.macports.org/) on Mac OS, available on Windows through [``cygwin``](http://cygwin.org/)):

```bash
$ bash --version | head -n1
GNU bash, version 4.3.42(1)-release (x86_64-pc-linux-gnu)
```

- And then install the kernel ``bash_kernel`` with these *two* commands:

```bash
sudo pip install bash_kernel
python -m bash_kernel.install
```

#### 2.b.2. [GNU Octave kernel](https://github.com/calysto/octave_kernel)
- You have to have [``octave``](https://www.gnu.org/software/octave/) installed (installable with the package manager on major Linux distributions (``apt-get``, ``pacman``, ``yum`` etc), installable with [``brew``](http://brew.sh/) or [``macports``](https://www.macports.org/) on Mac OS, available on Windows through [``cygwin``](http://cygwin.org/) or [natively](https://ftp.gnu.org/gnu/octave/windows/)):

```bash
$ octave --version | head -n1
GNU Octave, version 4.0.0
```

- Your version of Octave should be installed with [gnuplot]() support (it is usually the case):

```bash
$ gnuplot --version | head -n1
gnuplot 5.0 patchlevel 1
```

- And then install the kernel ``bash_kernel`` with these *two* commands:

```bash
sudo pip install octave_kernel
python -m octave_kernel.install
```

#### 2.b.3. [OCaml kernel: `OCaml-Jupyter`](https://github.com/akabe/ocaml-jupyter)
It is quite easy to install, with [opam](https://opam.ocaml.org/):
```bash
opam install jupyter
```

> I started by using this [OCaml kernel called IOCaml](https://github.com/andrewray/iocaml/wiki/jupyter).
> The instructions were not so simple, cf. the tutorial by @andrewray on [iocaml's wiki](https://github.com/andrewray/iocaml/wiki/).
> It was prone to some bugs, and [I had to manually implement a script](https://github.com/Naereen/fix-iocaml-notebook-exports-to-pdf) to be able to convert the notebooks to PDF with `jupyter-nbconvert --to pdf`.
> Note that [I also had to write a custom `Exporter`](https://github.com/Naereen/Jupyter-NBConvert-OCaml/) for `jupyter-nbconvert` in order to convert the notebooks to OCaml scripts (`.ml`).

# [Jupyter Notebooks](http://jupyter.org/) :notebook: by [Naereen @ GitHub](https://naereen.github.io/)

This repository hosts *a lot of* [Jupyter Notebooks](http://jupyter.org/), covering various subjects.
Everything is open-sourced under [the MIT License](https://lbesson.mit-license.org/), you can use any of these notebooks for your own teaching activities if you want. Please [open an issue](https://github.com/Naereen/notebooks/issues/new), or [ask me anything](https://github.com/Naereen/ama) or [drop an email](https://besson.link/callme.en.html) if you have any questions, suggestions, or more.

*Which languages?* Half of the notebooks here are in :gb: English, and the other half in :fr: French (surtout pour *l'agrégation de mathématiques option informatique*, dans ce dossier [`agreg/`](agreg/)), and most use [the Python language](https://www.Python.org/), or [OCaml](https://OCaml.org), and a few notebooks use other languages like Julia, Rust, Java or even Bash, C and Octave!

## How to read or use these notebooks?
You can view this repository on [nbviewer](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/) to read notebooks statically, or read them directly from GitHub.

You can also launch an interactive environment to play with the code by yourself, using one of these platforms:
- MyBinder should work fine even for OCaml notebooks, but it's quite slow. It's fully open-source, and reliable: [![MyBinder v2](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/Naereen/notebooks/master)
- Google Colab should work only for Python notebooks, but it's blazing fast to load. It's not open-source and requires to use Google's servers: [![Google Colab: Launch](https://img.shields.io/badge/Google%20Colab-Launch-blue.svg)](https://colab.research.google.com/github/Naereen/notebooks/blob/master/)

- **New!** In Feb'21, [I have installed](https://github.com/Naereen/Mon-utilisation-de-Basthon/) the amazing [Basthon notebook](https://basthon.fr/about.html) to my website, at <http://notebook.besson.link/>, and you can use it with any of the notebooks available in the repository, for instance <https://besson.link/Basthon/notebook/?from=../../publis/notebooks/Py_Pi_Day_2017.ipynb> for [`Py_Pi_Day_2017.ipynb`](Py_Pi_Day_2017.ipynb), because this folder is synced on my website at <https://besson.link/publis/notebooks/>. Please [open an issue](https://github.com/Naereen/notebooks/issues/new) if this doesn't work!

## My use of notebooks - short story since 2015

- At the beginning (as early as end of 2015!), this repository was only here to host some small experiments, for me to learn how to use [the wonderful Jupyter tools](http://jupyter.org/) correctly. So they were baby notebooks :baby_bottle:... Since then, I did *a lot of experiments*, on all the most important kernels (Python, Julia, but also less standard ones like OCaml, Rust, Java, C, Bash, etc), all the most exciting notebook extensions, and output formats (PDF, script, static HTML, slides, etc). I've kept learning and discovering more [awesomeness of the Jupyter environment](https://github.com/markusschanta/awesome-jupyter), and it never stops to amaze me :sparkles:!
- In the last 5 years (2016-2021), I've used Jupyter notebooks intensively, to teach algorithmics, programming, and (not so theoretical) computer science in general, mainly in :fr: French. I wrote notebooks to teach [introduction to Java in 2020](https://perso.crans.org/besson/teach/INF1_L1_Rennes1_2020-21/), [advanced algorithms using Python in 2019](https://github.com/Naereen/ALGO1-Info1-2019), and a lot for experimenting during [my PhD thesis](https://perso.crans.org/besson/phd/).
- :fr: J'ai aussi corrigé *tous* les textes d'annales de modélisation, en option informatique, pour le concours national de l'agrégation de maths, en utilisant OCaml ou des fois Python ! Ce sont les seuls corrigés de ce type disponibles sur tous les Internets (j'ai cherché partout !), et ils sont dans ce dossier : [`agreg/`](agreg/). [Je compte]() déplacer ça dans un dossier à part, et bien les nettoyer et mettre à jour, en 2021.
- I love the Jupyter environment, from the old [IPython command line](https://ipython.org/) to the recent [awesome](https://github.com/mauhai/awesome-jupyterlab) [Jupyter Lab](https://github.com/jupyterlab/jupyterlab). If you want to discover amazing things, check out: [RISE for live slides in a notebook](https://rise.readthedocs.io/), [lolviz](https://github.com/parrt/lolviz/) and [rcviz](https://github.com/DamnedFacts/rcviz) and [tutormagic](https://github.com/kikocorreoso/tutormagic/) for nice data structures visualizations in a notebook.

- In the future, **I plan to mostly teach using Jupyter notebooks**, using either the regular Python kernel, the [OCaml-jupyter](https://github.com/akabe/ocaml-jupyter/) kernel for [OCaml](https://ocaml.org) (and also [IJava](https://github.com/SpencerPark/IJava) for Java, [this one for C](https://github.com/brendan-rius/jupyter-c-kernel), and more if needed). RISE slides embed a chalk-board mode, more limited in comparison to the amazing [TableauNoir](https://tableaunoir.github.io/).

## A partial list of notebooks in this repository

I'm trying to maintain here a list of the notebooks stored in this repository, inspired by the amazing [pytudes](https://github.com/norvig/pytudes) by [Peter Norvig](https://github.com/norvig/).
The links open [nbviewer](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/)), and the links ([on GitHub?](https://github.com/Naereen/notebooks/)) open the notebook to be viewed directly in GitHub (it should work for almost all of them).

### :shell: Bash
- The first notebooks I wrote are small tutorials for :shell: `bash` commands (or some of my [command-line scripts](https://bitbucket.org/lbesson/bin/src/master/)), see for example [a tutorial on head and a tail](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Tutorial%20on%20head%20and%20tail%20%28bash%29.ipynb) ([on GitHub?](Tutorial%20on%20head%20and%20tail%20%28bash%29.ipynb)).

### :snake: Python
> I am a passionate user of [the Python programming language](https://www.python.org/).

#### Science
- [This notebook written for the Pi Day 2017](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Py_Pi_Day_2017.ipynb) ([on GitHub?](Py_Pi_Day_2017.ipynb)) demonstrates a dozen of easy algorithms to compute from 10 to 100000 digits of the *number pi*.

- [This notebook implements a simple example of the *simulated annealing* algorithm](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Simulated_annealing_in_Python.ipynb) ([on GitHub?](Simulated_annealing_in_Python.ipynb)) to minimize black-box functions :sunglasses:.

- [This notebook shows a hand-written and clear implementation](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Manual_implementation_of_some_hash_functions.ipynb) ([on GitHub?](Manual_implementation_of_some_hash_functions.ipynb)) of several [Hashing functions](https://docs.python.org/3/library/hashlib.html), like `MD5`, `SHA1`, and all variants of `SHA2` (`SHA256`, `SHA224`, `SHA512`, `SHA384`).

- [This notebook shows a manual implementation](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Short_study_of_the_Lempel-Ziv_complexity.ipynb) ([on GitHub?](Short_study_of_the_Lempel-Ziv_complexity.ipynb)) of the [Lempel-Ziv complexity](https://en.wikipedia.org/wiki/Lempel-Ziv_complexity) in pure Python, and then as optimized Python code, with Cython or Numba. I also wrote a version in [Julia](http://julialang.org) (in the same notebook), and compare the 4 implementations! I then published my code as a Pypy package, see [here on pypi.org](https://pypi.org/project/Lempel-Ziv_Complexity/).

- [This notebook shows a hand-written and clear implementation](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Manual_implementation_of_the_Mersenne_twister_PseudoRandom_Number_Generator__PRNG_.ipynb) ([on GitHub?](Manual_implementation_of_the_Mersenne_twister_PseudoRandom_Number_Generator__PRNG_.ipynb)) of several [Pseudo-Random Number Generators](https://docs.python.org/3/library/random.html), including the famous *Mersenne twister* algorithm, and then uses it to samples from the most famous discrete and continuous distributions, showcasing use of the Inverse-Transform method and Acceptance-Rejection method (cf. Markov Chain Monte-Carlo methods).

- [This notebook implements and compares different Runge-Kutta methods](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Runge-Kutta_methods_for_ODE_integration_in_Python.ipynb) ([on GitHub?](Runge-Kutta_methods_for_ODE_integration_in_Python.ipynb)) for integrating Ordinary Differential Equations in Python. And also [in Julia](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Runge-Kutta_methods_for_ODE_integration_in_Julia.ipynb) ([on GitHub?](Runge-Kutta_methods_for_ODE_integration_in_Julia.ipynb)), and also [in OCaml](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Runge-Kutta_methods_for_ODE_integration_in_OCaml.ipynb) ([on GitHub?](Runge-Kutta_methods_for_ODE_integration_in_OCaml.ipynb)). I wanted to compare the three languages for the same algorithms. Well, obviously, Julia is the fastest and simplest for numerical simulations like this.

- :fr: [Ce petit notebook en français](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Verification_de_numeros_CB_RIB_NIRPP_IBAN.ipynb) ([sur GitHub ?](Verification_de_numeros_CB_RIB_NIRPP_IBAN.ipynb)) implémente les algorithmes de vérifications des numéros de cartes bleues, de sécurité sociale et d'IBAN en Python.

- [This notebook implements and explore the Exponential Integral function Ei(x)](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Exponential_Integral_Python.ipynb) ([on GitHub?](Exponential_Integral_Python.ipynb)).

- [This notebook shows how to solve the equation `exp(- a x²)=x` both numerically and formally (with the Lambert W function)](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Solving_an_equation_and_the_Lambert_W_function.ipynb) ([on GitHub?](Solving_an_equation_and_the_Lambert_W_function.ipynb)).

- [This notebook implements Kullback-Leibler divergences for some parametric distributions, and KL-UCB indexes, in naive Python and compare with optimized versions using JIT compilation by Numba or C compilation by Cython](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Kullback-Leibler_divergences_in_native_Python__Cython_and_Numba.ipynb) ([on GitHub?](Kullback-Leibler_divergences_in_native_Python__Cython_and_Numba.ipynb)).

- [This short notebook defines and studies the Rényi entropy](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/A_short_study_of_Renyi_entropy.ipynb) ([on GitHub?](A_short_study_of_Renyi_entropy.ipynb)).

#### Experiments with Python
- [This small notebook](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Living_in_a_noisy_world_with_James_Powell_rwatch_module.ipynb) ([on GitHub?](Living_in_a_noisy_world_with_James_Powell_rwatch_module.ipynb)) is a fun experiment, where I tried to use [James Powell (@dutc)](https://GitHub.com/dutc) [rwatch](https://GitHub.com/dutc/rwatch) module to write a Python context manager to add a Gaussian white noise to every numbers inside the context... Something like: `with noise(): x = 10` will produce `x = 10.325` for instance... It fails, but I almost got it, and it works (without breaking the interpreter) for complex numbers. That's already intersting!

- [This notebook](https://nbviewer.jupyter.org/github/Naereen/notebooks/blob/master/Floating_point_error_propagation_in_polynomial_multiplication_with_Fast-Fourier_Transform.ipynb) ([on GitHub?](Floating_point_error_propagation_in_polynomial_multiplication_with_Fast-Fourier_Transform.ipynb)) is a small experiment, written quickly, about floating-point error propagation when using a non-naive polynomial multiplication with evaluation-and-interpolation. Sadly, this approach fails!

## 1. *How to read these documents*?

### 1.a. View the notebooks statically :memo:
- Either directly in GitHub: [see the list of notebooks](https://github.com/Naereen/notebooks/search?l=jupyter-notebook);
- Or on [nbviewer.jupiter.org](https://nbviewer.jupiter.org/): [list of notebooks](https://nbviewer.jupyter.org/github/Naereen/notebooks/tree/master/).

### 1.b. Play with the notebooks dynamically :boom:
[![MyBinder](http://mybinder.org/badge.svg)](http://mybinder.org/repo/Naereen/notebooks)

Anyone can use the [mybinder.org](http://mybinder.org/) website (by [clicking](http://mybinder.org/repo/Naereen/notebooks) on the icon above) to run the notebook in her/his web-browser.
You can then play with it as long as you like, for instance by modifying the values or experimenting with the code.

You can also launch an interactive environment to play with the code by yourself, using one of these platforms:
- MyBinder should work fine even for OCaml notebooks, but it's quite slow. It's fully open-source, and reliable: [![MyBinder v2](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/Naereen/notebooks/master)
- Google Colab should work only for Python notebooks, but it's blazing fast to load. It's not open-source and requires to use Google's servers: [![Google Colab: Launch](https://img.shields.io/badge/Google%20Colab-Launch-blue.svg)](https://colab.research.google.com/github/Naereen/notebooks/blob/master/)

- **New!** In Feb'21, [I have installed](https://github.com/Naereen/Mon-utilisation-de-Basthon/) the amazing [Basthon notebook](https://basthon.fr/about.html) to my website, at <http://notebook.besson.link/>, and you can use it with any of the notebooks available in the repository, for instance <https://besson.link/Basthon/notebook/?from=../../publis/notebooks/Py_Pi_Day_2017.ipynb> for [`Py_Pi_Day_2017.ipynb`](Py_Pi_Day_2017.ipynb), because this folder is synced on my website at <https://besson.link/publis/notebooks/>. Please [open an issue](https://github.com/Naereen/notebooks/issues/new) if this doesn't work!

> *Note:* Only the Python kernel is supported on the MyBinder interface!

----

## 2. *Requirements to run the notebooks locally*?
All [the requirements](requirements.txt) can be installed with [``pip``](https://pip.readthedocs.io/) and by running a few ``python -m ...`` commands.

> Note: if you use [Python 3](https://docs.python.org/3/) instead of [Python 2](https://docs.python.org/2/), you *might* have to *replace* ``pip`` and ``python`` by ``pip3`` and ``python3`` in the next commands (if both pip and pip3 are installed).

> :warning: I've not updated this section since 2016.

### 2.a. [Jupyter Notebook](http://jupyter.readthedocs.org/en/latest/install.html) and [IPython](http://ipython.org/)

```bash
sudo pip install jupyter ipython
```

It will also install all the dependencies, afterward you should have a ``jupyter-notebook`` command (or a ``jupyter`` command, to be ran as ``jupyter notebook``) available in your ``PATH``:

```bash
$ whereis jupyter-notebook
jupyter-notebook: /usr/local/bin/jupyter-notebook
$ jupyter-notebook --version  # version >= 4 is recommended
4.2.1
```

### 2.b. Other kernels (*optional*):
> They are only needed to run the notebooks written for Bash or Octave (or OCaml):

#### 2.b.1. [GNU Bash kernel](https://github.com/takluyver/bash_kernel)
- You have to have [``bash``](https://en.wikipedia.org/wiki/Bash_(Unix_shell)) installed ([already there](https://tiswww.case.edu/php/chet/bash/bashtop.html) on all Linux distribution, installable with [``brew``](http://brew.sh/) or [``macports``](https://www.macports.org/) on Mac OS, available on Windows through [``cygwin``](http://cygwin.org/)):

```bash
$ bash --version | head -n1
GNU bash, version 4.3.42(1)-release (x86_64-pc-linux-gnu)
```

- And then install the kernel ``bash_kernel`` with these *two* commands:

```bash
sudo pip install bash_kernel
python -m bash_kernel.install
```

#### 2.b.2. [GNU Octave kernel](https://github.com/calysto/octave_kernel)
- You have to have [``octave``](https://www.gnu.org/software/octave/) installed (installable with the package manager on major Linux distributions (``apt-get``, ``pacman``, ``yum`` etc), installable with [``brew``](http://brew.sh/) or [``macports``](https://www.macports.org/) on Mac OS, available on Windows through [``cygwin``](http://cygwin.org/) or [natively](https://ftp.gnu.org/gnu/octave/windows/)):

```bash
$ octave --version | head -n1
GNU Octave, version 4.0.0
```

- Your version of Octave should be installed with [gnuplot]() support (it is usually the case):

```bash
$ gnuplot --version | head -n1
gnuplot 5.0 patchlevel 1
```

- And then install the kernel ``bash_kernel`` with these *two* commands:

```bash
sudo pip install octave_kernel
python -m octave_kernel.install
```

#### 2.b.3. [OCaml kernel: `OCaml-Jupyter`](https://github.com/akabe/ocaml-jupyter)
It is quite easy to install, with [opam](https://opam.ocaml.org/):
```bash
opam install jupyter
```

> I started by using this [OCaml kernel called IOCaml](https://github.com/andrewray/iocaml/wiki/jupyter).
> The instructions were not so simple, cf. the tutorial by @andrewray on [iocaml's wiki](https://github.com/andrewray/iocaml/wiki/).
> It was prone to some bugs, and [I had to manually implement a script](https://github.com/Naereen/fix-iocaml-notebook-exports-to-pdf) to be able to convert the notebooks to PDF with `jupyter-nbconvert --to pdf`.
> Note that [I also had to write a custom `Exporter`](https://github.com/Naereen/Jupyter-NBConvert-OCaml/) for `jupyter-nbconvert` in order to convert the notebooks to OCaml scripts (`.ml`).
