After a couple of hours debugging why my Proxmox LXCs had no outbound Internet, I found that they were sending DHCPDISCOVER packets but never receiving a DHCPOFFER.
Software resets didn’t help. Neither did rolling the UniFi switch back to older firmware.
What finally fixed it was physically disconnecting and reconnecting the 10GbE SFP+ link, even though UniFi showed it as up the entire time.
I believe this is the second time I’ve seen this behavior.
Use kebab-case in Spring Boot @Value placeholders to avoid configuration-name headaches later.
For properties loaded from Config Server:
@Value("${demo.item-price}") matches both demo.item-price and demo.itemPrice.@Value("${demo.itemPrice}") matches only demo.itemPrice.This means a camelCase placeholder is coupled to that exact property spelling. If the Config Server property is later standardized to kebab-case, the lookup breaks.
A kebab-case placeholder supports both forms, making it the safer convention for existing configuration and future changes.
Verified this behavior on Spring Boot 2.7, 3.2, 3.3, 3.5, and 4.0.
Rectangle v0.96 is out with my shortcut-cycling patch.
One shortcut can now be assigned to multiple actions, and repeated presses cycle through them.
Tiny workflow fix. I probably wouldn’t have made time for it without Codex.

I always thought “a” vs. “an” was based on the written first letter: use “an” before words starting with vowels - a, e, i, o, u.
But some words felt weird when I wrote them, and I never noticed which article I was using when speaking.
Turns out the actual rule is based on pronunciation, not spelling:
The more you know.
