A better way would be to share a folder to their Dropbox email account, so you only expose to them what you want.

The best way would be to make desktop software that did the required tasks without exposing third parties to the data at all.

Wouldn't That count towards the overall size limit of their Dropbox account and fill up quickly?

This projects onto the road ahead of the bike, hopefully making your presence known even if you weren't visible (blind spot, for example).

If it only shows up on the ground, near the side of the front of the car, this won't work. I'll never see it.

If this is more like a visible beam, that is also very visible before it hits the tarmac (which I doubt), then it's essentially a torch. We have those.

I didn't know about the one-per-line option, so thanks for that.

Commands I use regularly instead of using ifconfig:

  # link up/down
  ip link set dev eth0 up|down

  # add a new address
  ip addr add dev eth0 172.16.43.124/24

  # to clear all IP addresses from eth0
  ip addr flush dev eth0

  # delete an address
  ip addr del dev eth0 172.16.43.124/24

  # add default route
  ip route add default via 172.16.43.254

And what is wrong with

  ifconfig eth0 up|down?

Why would I want to type more to accomplish the same task?

This is the same reason as to why I hated that Linux decided to have an ifconfig for physical interfaces, an iwconfig for wireless interfaces. It seems redundant...

Nothing, as long as it's working for you (your Linux distribution probably patched some of the remaining ifconfig problems themselves). You likely won't have a problem until you want to use network features that were implemented after 2001.

Yep, I'm fully aware of ifconfig. I use "ip link" just out of habit, and, given that ifconfig is apparently deprecated, it might disappear some day.

Anyway, the point of my post was showing some basic things which can be done with ip, and how to do them.

Really not you. It's one way this site is too minimal.

As a general rule of thumb, I like the 10/20/30 rule: 10 slides, 20 minutes, 30pt font.

I'm not a fan of speaking (although I'm starting to come round to it) and I tend to waffle both on the slides and when talking, so this helps me to keep focused.
