+FOSS4G 2006 Conference
++ Lausanne, Switzerland, September 2006 +
++ It was a great success. It was the first joint conference that brought together the different FOSS4G "tribes", + merging the GRASS Users conference series, with the Mapserver, EOGEO and Java developers meetings. ++

GRASS GIS is command-line only, no?
+
+GRASS GIS is only a desktop GIS, no?
+
+Interface options
+Python
+ Python API comes with GRASS GIS. ++
+R
+ rgrass package to use GRASS GIS from R is on CRAN. ++
+QGIS
+ GRASS tools are available through the Processing Plugin(GUI and Python). +
+
+Command Line
+-
+
- Interactive shell +
- One-time execution or batch usage with
--exec
+
+
+Cloud
+-
+
- CLI +
- Python +
- actinia +
- OpenPlains +
+
+Graphical User Interface
+No startup screen
+ Startup screen was a stumbling block for many first-time users. +
+Project Loaded on Start
+ Desktop GRASS GIS starts with a project loaded(last-used or default). +
+Streamlined Data Management
+ New Data tab is a central place to manipulate data in a project. +
+Location is Becoming a Project

Multiple windows
+ Multiple windows was the only option. ++ Still available as before, but… +
+
+Single-window Interface
+ Now single-window interface is the default. +
+Happy 40th birthday, GRASS GIS!
+
+Time to clear up some misconceptions related to age
+Funding
+It’s been around for long, so it must be well-funded
+How people imagine a GRASS developer
