#TIL about #Visidata: jsvine.github.io/intro-to-visi

If you ever need to wrangle, filter, sort, edit, navigate, subset or get basic statistics out of #data in #CSV format (comma-separated values), this is a super useful piece of software. It takes raw data and implements a very handy subset of functionality from spreadsheets directly on top, with both a keyboard (modal Vi-style operation) and menu/mouse driven operation.

Nice one to have in the toolchest.

Not sure who needs this (apart from me, of course), but just pushed my rof2csv tool:
github.com/branch-predictor/ro
Use it to convert Rigol's ROF files (produced by Rigol DP800 series programmable power supplies) into CSV files that can be fed into Excel or LibreOffice Calc.
