Notes

I am one of those people who function better by writing things down. One day, I realized that most of my notes don’t have to be private, so here they are - my second brain. Be warned that, if you stumble upon something here that doesn’t make sense to you, it isn’t meant to!

Describe AWS EC2 instances

Given an instance-id alone: aws ec2 describe-instances --instance-ids i-001fa90ce5949539f i-0ffbee16785c3cab4 With filters: aws ec2 describe-instances \ --filters "Name=instance-type,Values=m5d.metal" "Name=instance-state-name,Values=running" "Name=image-id,Values=ami-foo" \ --no-paginate \ Other filters: "Name=instance-id,Values=i-0bf18c34a79da1027" Can also add the following: | jq -r ".Reservations|.[]|.Instances|.[]|.PublicIpAddress" | jq -r ".Reservations|.[]|.Instances|.[]|.Placement.AvailabilityZone" Resources: https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-instances.html

Dumbbell-only workouts

https://www.muscleandstrength.com/workouts/dumbbell-only-home-or-gym-fullbody-workout.html https://forum.bodybuilding.com/showthread.php?p=1266579671#post1266579671 - only 2 days a week, so maybe not enough volume. https://www.reddit.com/r/Fitness/comments/2e79y4/dumbbell_ppl_proposed_alternative_to_dumbbell/ https://www.muscleandstrength.com/workouts/frankoman-dumbbell-only-split.html - probably split the last section into two days. Splits across muscles - do once I have made some gains from some other programs. https://www.muscleandstrength.com/workouts/dumbbell-only-upper-lower-workout-routine - looks good. Maybe do after working full body for 3-4 months.

Format USB drive with ext4 format

Format drive: sudo mkfs.ext4 /dev/sda1. (This will only succeed after unmounting the drive.) The drive will have root permissions. Change that using: sudo chown -R pi /media/pi/867db593-eb76-486a-990c-409216265ae1/.

Glacier National Park

Seems to be awesome. Rafting until mid july. Some hikes here. July/August seems to be the best time. Expensive flights to Glacier Park International Airport, 10 hour drive from seattle. Also: The pros about coming in summer are that most of the trails are open, the flowers are blooming and the weather is nice (usually).July and August is our summer.
