I recently learned that AWS internet gateway does a one-to-one destination NAT for public IPs inside a VPC, this includes public load balancers and elastic IPs (EIPs) on EC2 instances. So for any inbound IP filtering rules I need get the private IP addresses of the resources (if filtering by destination IP).

The closest documentation I could find of this behaviour talks about this in regards to EIPs:

traffic that's destined for the public IPv4 address or Elastic IP address of your instance has its destination address translated into the instance's private IPv4 address before the traffic is delivered to the VPC.

Seems logical in hindsight but led to some fun troubleshooting.

TIL the ThinkPad was named after literal Think notepads distributed by IBM.

From Wikipedia:

For decades, IBM had also distributed small notepads with the word "THINK" emblazoned on their cover to customers and employees. The name "ThinkPad" was suggested by IBM employee Denny Wainwright, who had one such notepad in his pocket.

Ryan Barrett does a good job summarising tech roles. Now if only ask management would actually understand the this...

Looks like version 2.2.15 of miniflux supports fetching RSS feeds for a YouTube channel along with videos only, shorts or live streams. This is achieved by prefixing the channel ID with UULF for videos, UUSH for shorts, and UULV for live streams. This morning I included this into YT-RSS so you can now get these individual feeds through there as well.

TIL YouTube playlists have RSS feeds you can subscribe to, just like channels. For every new video that gets added, a new entry pops up in the RSS feed.

I learned this thanks to @Zegnat, who added a feature to YT-RSS allowing you to retrieve the feed URL of YouTube playlists (among some other backend code improvements)!
