#### Post date: [September 30, 2021, 11:39am UTC](https://clojureverse.org/t/re-clojure-2021-pre-conference-workshops/8216/1 "2021-09-30T11:39:28Z")
The [re:Clojure 2021](https://www.reclojure.org) conference is about two months away. One of the things that will happen even sooner is the series of pre-conference workshops. In this post we wish to tell what they are about, and suggest a few ways you may be involved in creating and having them.
## What are they?
The pre-conference workshops are part of the re:Clojure celebration. Their goal is to allow the broad Clojure community a learning experience about some parts of the emerging ecosystem.
This time, many of the workshops will be related to data science, and organized in collaboration with the Scicloj community. It will be a good time to look into a few of the libraries and tools that have been growing there and are now maturing gradually.
Most workshops will take place during November and will be self-contained sessions of 1 or 2 hours. One person will be explaining and demonstrating, and the participants will listen and participate, possibly trying things at their environment where it makes sense. The same topic may repeat a few times throughout the month. The format will be somewhat similar to the various weekly Scicloj study sessions, but a bit more scripted, preferring clarity over exploration. We may try out other formats as well, sometimes. Below you can find the current tentative wishlist.
## Getting involved
We would love to hear your thoughts about all this. Are you interested in participating? Do you have any ideas for topics or other aspects of the workshops? Would you like to be involved in orgaizing, teaching a workshop, moderating a worksohp, or assisting participants?
Please note that some of the topics are very much learnable and teachable. This means that any Clojurian who likes to teach can present them well with some preparation. If you’d like to help in teaching one of those topics, let us talk.
If you wish to suggest a topic of your own, we would love to talk too and see if we can help you in turning it into a workshop.
See you there,
re:Clojure & Scicloj

We’re still looking for a person to teach a basic workshop about linear algebra with [Neanderthal](https://neanderthal.uncomplicate.org/). There is no need to be an expert, just to have the time and attention to prepare a nice session.
Other additional topics are very much welcome too.

Hi!
The November workshops will need moderators – people who will be there and assist the teacher: possibly presenting the topic and teacher, announcing some info about other workshops, being minded to the clock, asking some clarifying questions, checking the chat for questions, etc.
If this is something that you like to do, please tell me.

The re:Clojure workshops are continuing in the coming couple of days:
@bsless – Structure and Interpretation of Clojure Transducers
[zulip thread](https://clojurians.zulipchat.com/#narrow/stream/305782-nov21-workshops/topic/transducers-2021-11-15)
Transducers are a powerful abstraction added relatively recently to Clojure. In spite of this and the noticeable performance benefits, they remain a daunting subject for many Clojurians. There is no reason such an important subject remain impenetrable. We will approach them in this workshop from first principles and see how they emerge naturally as a general property in many places. By the end of the workshop, participants will have a better understanding of transducers, their use cases, and will be comfortable writing their own simple transducers when the need arises.

Rohit Thadani – An Intro to Statistical Inference
[zulip thread](https://clojurians.zulipchat.com/#narrow/stream/305782-nov21-workshops/topic/stats-2021-11-16)
Useful inferential statistics does not have to be just the domain of data scientists. This workshop follows examples in the book “Statistics is Easy” to demonstrate concepts of fairness, p-value, confidence intervals, power using resampling and bootstrapping. All concepts will be explained purely using functions from the core clojure library.

Your Namespace as a Notebook
Notespace allows the creation of visual documents without leaving the comfort of the familiar Clojure editor, REPL, and namespace. It has evolved through usage in the Scicloj community. We will practice basic use of Notespace, discuss its design choices and relationship to other projects, and chat about future challenges.

Machine Learning Through Pipelines
Daniel Slutsky
Scicloj.ml is a Clojure library by Carsten Behring that connects many aspects of machine learning workflows into one coherent stack. It is based on a certain notion of a pipeline, implemented in the libraries Metamorph and Metamorph.ml. In this session we will discuss some of the core ideas behind these libraries and look into solving a data modelling problem using Scicloj.ml.

Touring Oz: Notebooks, Visualizations, and Webapps, Oh My!
Christopher Small
Oz is a Swiss Army Knife for data visualization, scientific documentation, and “namespace as a notebook” style analysis workflows. However, its versatility can make it easy to miss the full scope of its capabilities. In this workshop, we’ll briefly go over all of its features, and then work through a series of illustrative examples based on participant interest.

Linear Algebra with Neanderthal
David Pham
In order to operate mathematics on collections of numbers, the easiest solution is to use for-loop. I assumed it was the fastest way until I discovered Neanderthal, a linear algebra built for Clojure. This workshop introduces the most basic linear algebra concepts so that you can also enjoy Neanderthal. My aim will be to show you the underlying intuition so that these squares of numbers and formulas won’t scare you when you read them.

Writing Web Apps with Fulcro
Jakub Holý
Fulcro is unique among Clojure web frameworks in providing a complete, integrated, full-stack solution for creating non-trivial web applications. It is based on a few simple ideas with far-reaching consequences, it is unusually malleable, and we love it for its focus on creating maintainable, developer-friendly code. In this workshop you will get a brief introduction to Fulcro and then get your hands dirty exploring the concepts in practice on an existing application in a series of guided exercises. We will use the excellent Fulcro Inspect tooling and mess up with the code. Please do the preparation described at [GitHub - holyjak/fulcro-intro-wshop: Introduction to creating webapps with Fulcro workshop held during re:Clojure 2021](https://github.com/holyjak/fulcro-intro-wshop#prerequisites) before the workshop.
