Weekly: AWS and Keyboards

As I am helping another team part time to setup some infra on AWS, I felt my fundamental AWS knowledge being tested all over again. I’ve gotten so used to doing the more “tricky/complex” things that when starting from fresh, got tripped up by some basic setup.

  • Internet facing ELB must have public subnet associated
  • As long as the each AZ has a public subnet associated, the ELB will be able to route to the AZ
  • Public subnets must have IGW, NAT not counted
  • NAT instance must be created in a subnet which has IGW
  • ELB does not need to be in the same subnet as Target Group to route to it
  • ELB needs at least a /27 subnet
  • ELB reserves 8 IP in the subnet for autoscaling
  • NLB does not load balance cross-zone by default
  • ALB load balance cross-zone by default
  • Smallest subnet in AWS is /28
  • OpenVPN Access Server needs EIP
  • OpenVPN Access Server needs to setup through SSH first

While I wasn’t the one who setup the bulk on the networking, I wasn’t able to quickly pinpoint the exact reason why I was unable to get connectivity for the VPN that I was setting up. Just proves that there are some fundamental concepts that I need brushing up on.

On happier news, I finally bought/receive the lube for my future keyboard. Over the weekends I decided to try lubing my current Filco TKL keyboard without disassembly to see how it works/feels.

Weekly: diving deeper into keyboards

This week I finally made the plunge into the slightly deeper end of the mechanical keyboard community. I made the pre-order for Drop’s Ctrl Keyboard (Halo True switches). Total damage after shipping: 201.05 USD.

It’s my first step into the custom keyboard modding community. I was contemplating for the longest time if I should build a totally custom keyboard from scratch from sites like kbdfans for example. But the high cost of entry and the fear of screwing up made me decide to go for a semi-custom route instead.

However, while waiting for the keyboard to come, I decided to do some slight modifications to my Filco keyboard to see if I could improve the feel and sound of it.
