+  * Per Paper
+  * Per Study/Project 
+  * Per Collaborator
+* Keep <b>readme files</b> for data  
+  * Title
+  * Date of Creation/Receipt
+  * Instrument or software specific information
+  * People involved
+  * Relations between multiple files/folders 
+
+* Separate files you are actively working from the old ones  
+* Orient newcomers to the group's conventions
+
+
+
+# Data housekeeping
+<div style="position:absolute">
+
+## When working 
+  * Clarify and separate source and intermediate data
+  * Keep data copies to a **minimum**
+  * Cleanup post-analysis
+  * Cleanup copies created for presentations or for sharing

+    * context of generation
+    * data structure
+    * content
+  * sensitive data (e.g. whole genome) **must** be encrypted

+# Data housekeeping - Summary
+## Server is your friend!
+  * Allows a consistent backup policy for your datasets
+  * Keeps number of copies to minimum
+  * Specification of clear access rights
+  * High accessibility
+  * Data are discoverable
+  * Server can't be stolen
+  
+## General guidelines
+  * Use institutional media for storage of **all** data
+  * Research data (particularly sensitive data) should be in a single source location
+  * Enable encryption for data stored on movable media
+  * Clarify and separate source and intermediate data
+  * Disable write access to relevant source data (read-only)
+  * Backup research data!
+  * Download Anti-virus software
+  * Generate checksums

+# Problem solving
+A guide for solving computing issues
+
+1. Express the problem 
+  * Write down what you want to achieve
+2. Search for help 
+  * Read **FAQs**, **help pages** and the **official documentation** well before turning to Google
+  * Use stack exchange, forums and related resources carefully
+3. Ask an expert 
+    * You have to submit the problem in writing
+    * Make the question interesting
+    * If you supply a trivial problem, it will stop answering
