Please don't forget to give what you can this year, we can't come close to filling the gap that our government has created but it still matters
Most Americans aren’t making end-of-year charitable giving plans, according to the results of a new AP-NORC poll, despite the many fundraising appeals made by nonprofits that rely on donation surges in the calendar’s final month to reach budget targets. https://to.pbs.org/4prpLIt

UGH. GenAI Slop spreading: HR tool replaced simple "show PTO balance" with Chatbot (ditto for requesting time-off). Much worse interface, strictly inferior, costlier all around.
Initial feeling was "fuck this shit -- I'm out".
What is this even? Some corporate goals for "Use. MORE. AI!"?!?

Liking Claude Code even more: I'm slow adopter, but today got into tool-making; asked Claude to write a script to find all `jackson-databind` issues with 5 or more upvotes.
1-shotted nice Python script that called Github API and it... Just Worked.
Old News I know. But I'm getting there.

/5 Now. Members of the United States military are not obligated to follow unlawful orders. This is baked into the law; it’s not subject to dispute. A soldier refusing an order will have to establish the order was ”manifestly unlawful.”

Had forgotten approx. size of Jackson codebase, checked. Somewhat smaller than I thought. FWTW, LoCs:
1. `jackson-core` (streaming JSON read/write): ~60k
2. `jackson-databind` (Java Object mapping): ~135k
3. `jackson-annotations`: ~6k
(2.20.0 and 3.0.0 very similar).
So abt 200k of Java for core
1. `jackson-core` (streaming JSON read/write): ~60k
2. `jackson-databind` (Java Object mapping): ~135k
3. `jackson-annotations`: ~6k
(2.20.0 and 3.0.0 very similar).
