Problem
We need more RAM. We don't want to open up the computer just to see if there's a free slot.
Solution
sudo lshw -short -class memory
H/W path Device Class Description
=======================================================
/0/0 memory 64KiB BIOS
/0/4/5 memory 32KiB L1 cache
/0/4/6 memory 256KiB L2 cache
/0/4/7 memory 3MiB L3 cache
/0/41 memory 4GiB System Memory
/0/41/0 memory 2GiB SODIMM DDR3 Synchronous 1067 MHz (0,9 ns)
/0/41/1 memory DIMM [empty]
/0/41/2 memory 2GiB SODIMM DDR3 Synchronous 1067 MHz (0,9 ns)
/0/41/3 memory DIMM [empty]
The last 5 lines mean that we have 2 modules of 2GiB each, and 2 free slots.
