Loving the Law of the Lord

How I love your law!
I think about it all day long.

–Psalm 119:97 GNB

Psalm 119 is full of verses like this. When I get to one I usually try to rationalize it by thinking something along the lines of: “that’s more of an old testament posture to take towards the law, now that Jesus has died and risen, we have grace, so the law is merely a contrast to God’s radical grace. If I were to take up the posture of loving the law I’d be on a slippery slope to a life of legalism.”

However, recently I ran across an excellent series of videos covering the Ten Commandments from Luther’s Small and Large Catechisms. I heartily recommend the series because it teaches a way to love the law but still avoid legalism. Like many good treatments it reminded me of some things I already knew, but also revealed new things I had never known; speaking to both my mind and my heart.

There are 33 videos ranging from 5 to 16 minutes each.

The Lutheran ordering of the commandments is probably different from what you are used to (unless you are Lutheran.) The fifth video goes over the different orderings of the commandments. There are more variations than I knew!

Drone Pathfinding algorithm

via The Verge: Autonomous search-and-rescue drones outperform humans at navigating forest trails

This is really cool.

However:

1) Only at the very end do you see the custom built drone that is actually running the algorithm on an onboard computer, it doesn’t look like it does very well. (the previous shots are from a quadcopter controlled by a laptop carried by a person)

2) The Verge title states “autonomous search-and-rescue drones” as if that is a thing that exists. It doesn’t, this algorithm may one day be used effectively in an autonomous drone.

3) Search and Rescue isn’t always following a trail, it takes place in areas that are extremely remote. This sort of drone may possibly be useful, if the algorithm is improved, and batteries are improved, and lost hikers stay near the trail. Perhaps it could run down trails quickly looking for signs of lost hikers. But to do that it needs to actually be autonomous.
