We’re still here!

In this week’s show:

• Laura interviews Catherine Jones, New Media Engineer at the Science Museum in London, about building interactive displays.

• We discuss bringing an O2 Joggler back to life, and fixing bugs ready for the next beta of Ubuntu MATE.

• We share a Command Line Lurve – ps_mem:

A utility to accurately report the in core memory usage for a program. Available from the ps_mem GitHub.

• Download

wget https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py
chmod +x ps_mem.py

• Get a memory usage report, with child processes aggregated under the parent:

sudo ./ps_mem.py

• When you need to split the child processes use -s (for example, seeing what multiple Java applications use when running under a common servelet container such as Jetty or Tomcat):

sudo ./ps_mem.py -s

• The [-p PID,...] option allows filtering the results. To restrict output to the current $USER:

sudo ps_mem -p $(pgrep -d, -u $USER)

• And we go over your feedback – thanks for sending it – please send more!
