We have had the EcoAims PP500 laser pistol for modern pentathlon competitions for a few months now and used it out of the box without any adjustments. Recently I found a new place at home which made a decent ten metre range however no of us could hit the target. From five metres it was generally fine but pulled a bit to the left but we compensated for it. At ten metres we were off by easily ten cms so I needed to adjust the rear sight.
This is a follow on post to Setting Up a Private NPM Repository with Yarn and Verdaccio to illustrate publishing to Verdaccio. Verdaccio seems to work pretty well as a NPM proxy and private registry and comes with a web UI to browse your published packages and their dependencies.
Finally some bright sparks have worked out how to do public key encryption that most people could manage - not my mother-in-law - but the barriers to entry have been lowered a lot. Keybase uses or wraps PGP so they have not invented anything new but have “wrapped” it in a nice desktop (Electron I think) and device UI.
