PsychoPy on Linux


We've been using PsychoPy in our lab for a few years now, developing mainly on Linux, but often collecting data on Windows (shared testing facilities). On the basis of this experience, I recommend installing PsychoPy on Linux thus:

sudo apt install psychopy

This gives you quite an out of date version (1.85.3, released Aug 2017, for Ubuntu 18.04, as of Dec 2018), but trying to build it from source, or with pip, is just a huge time sink, often fails, and can kinda mess up your system in the process.  

This leads to a further recommendation. For archive purposes, archive your .py file as well as your .psyexp file, as more recent versions of Builder produce .psyexp files that are not backwards compatible!  

In fact, for portability, seriously consider treating PsychoPy mainly as a Python library, and develop experiments entirely as .py files, i.e. avoid Builder entirely. Builder is a good teaching tool, but anyone who can write R scripts can also learn how to write experiments directly in Python.

Doom (2016) on Linux


https://proxy.duckduckgo.com/iu/?u=http%3A%2F%2Fwww.videogamesblogger.com%2Fwp-content%2Fuploads%2F2016%2F05%2Fdoom-2016-walkthrough-640x325.jpg&f=1

Valve recently announced Steam Play, a system that allows previously Windows-only games to be played on Linux. It's in beta at the moment, but I thought I'd give it a go with Doom (2016). After a bit of a faff, it seems to work pretty well. The faff was that, on initially running, you just get a black screen. A search through the forums revealed that ALT+Enter brings it into a window on the desktop (rather than fullscreen), and it then works. From there, you can press ESC to bring up the game options, and set it back to fullscreen. Played for about an hour - works pretty well!

Of course, Doom 2016  not open source ... but it's still interesting how good Linux is getting as a games platform.

Goodbye Hush Coffee


Hush Coffee, Plymouth -- where the Plymouth meetings of the Devon & Cornwall Linux User Group started, perhaps 20 years ago - just closed its doors for the last time. Very sad. Now on the hunt for a new home...
