Pair up with your neighbour. 2. Download* the data file. 3. Do not modify the file. A (very) good practice: raw data should never be modified! 4. Document the issues you encountered in the chapter [_challenge 3_](https://hackmd.io/IucYoto4SnmMYAJowJ9Uvw?view#Challenge-1) of the hackmd.

The coding club is held monthly on alternate Tuesday and Thursday, from 10 a.m. to 12 a.m., in Herman Teirlinck building (Tour & Taxis, Brussels). <br>  --- class: left, middle ## So, practically... - The coding club is typically limited to 25 participants (room capacity). It will soon increase to 40 from Jan, 2020 onwards - Each session focusses on a specific theme and is <u>independent</u> from previous sessions - No laptop, no party. We code, after all! --- class: center, middle ## Who organises the coding club? The dream team  --- class: left, middle ## Tasks The core team takes care of: - reservation of the lecture room - thematic topics, working material and some challenges to work on - general agenda: __take into account feedback from participants!__ - documentation for [participants](https://inbo.github.io/coding-club/gettingstarted.html) and [organizers](https://inbo.github.io/coding-club/workflow.html) (step-by-step workflow to organize a coding club) - [code of conduct](https://github.com/inbo/coding-club/blob/master/.github/CODE_OF_CONDUCT.md) --- class: left, middle ## Did we figure that out ourselves? No :-) <br> <br /> Some initiatives we got inspiration from: - [ourcodingclub Edinburgh](https://ourcodingclub.github.io/). - initiatives showing that coding together can sensibly improve ecological/environmental research. See the [Ocean Health Index project paper](https://www.nature.com/articles/s41559-017-0160). - Software and Data Carpentry organisation: bye bye coding fear! See their inspiring [ecology workshop](http://www.datacarpentry.org/lessons/#ecology-workshop). --- class: center, middle ## Resources INBO coding club material is open and available online. Take a look, get inspired and inspire us. <br> <br /> https://inbo.github.io/coding-club/ --- class: left, middle ## Discussion So far our experience taught us: 1. Start easy: we started with a shared directory on Google Drive... 2. [DOCUMENTATION for participants](https://inbo.github.io/coding-club/gettingstarted.html). 3. [DOCUMENTATION for maintainers](https://inbo.github.io/coding-club/workflow.html) <br> Ideas? Questions? Doubts? We will try to track all in [hackmd chapter Discussion](https://hackmd.io/IucYoto4SnmMYAJowJ9Uvw?view#Discussion). --- class: center, middle  Room: Herman Teirlinck - 01.16 - Rik Wouters<br> Date: __24/10/2019__, van 10:00 tot 12:00<br> Title: strings manipulation<br> (registration announced via DG_useR@inbo.be)
