i'm beginning to understand the appeal of HCL as a configuration format over YAML. HCL has built-in variables, effectively providing a native templating engine. with YAML, we often have to use macros just to battle the indentation and ensure the correct number of spaces with some Jinja variants. 😲

in my earlier understanding, distributed systems usually featured a fine-grained metadata service for cluster membership. however, I've recently noticed that many systems' implementations seem to prefer a fixed cluster design. 🤔 once the cluster is established, its membership becomes immutable.

it seems there's no gold-standard benchmark for coding models at the moment. imho, the only way to know if one is any good is to throw a (real world) task at it and see if it can handle it smoothly 🤔.
