It's a bit unfair that you only quote "No.", as the full response was:

> No. Nobody has added any such functionality (yet). Feel free to work on that.

If someone thinks a feature can be useful, especially in the era of agentic coding, instead of asking, do it.

The same can be said about software engineers. The tricky thing is, it's hard to separate a subset of knowledge from the whole, for both human beings and LLMs

In case anyone is curious, check out https://debug.com/ (Google x Singapore government project on mosquito control, and yes, very cool domain)

> if no lab can keep a lid on their agents

Then stop experimenting until they know how to do it safely. Just think about it, if a bio lab doesn't know how to contain the virus they are experimenting with, would you just shrug and say ok?

yeah I found it out a while back and since then I've been using randomly generated names during checkout every time - no issues ever

no one is saying Apple is the saint. It's just better in comparison to other big techs who want your privacy as much and don't even pretend to care

It depends on your lens, some may think it's a way to show them the doors after failed corp politics.

Is it surprising? Let's face it - distillation is common practice and every lab does it either intentionally or unintentionally (your training corpus always includes AI generated content in the post ChatGPT era).

There are zero-retention 3rd party providers (EU/US companies), but it's your choice whether to trust their claims or not.

Made in Shanghai Gigafactory. Some may even argue Tesla would have died without the manufacture capacity in China

Fintech/finance is a very big industry and there are a lot of sub-domains. A HFT system programmer thinks about how to colocate their prod machines in NYSE and use zero alloc techniques to ingest marketdata as fast as possible, while a crypto wallet app developer spend more time designing cool UI to attract users and working out all the L1/L2 quirks. And I'm sure they have very different answers to whether to use integers and how many digits to preserve

I'm a programmer and I understand Git internals decently well, but unless something went wrong, I pay zero attention to the verbose output of `git push`. BTW, isn't "avoid unnecessary output" one of the Unix philosophies?

yeah this is indeed a good insight. Back in the days, who would expect so many bots to "review" code and leave overly verbose comments under every PR in a popular repo?

New comment by zackwu in "Put the zip code first"

zackwu — Mon, 09 Mar 2026 02:03:48 +0000

As pointed out by many comments, the post seems US-centric and using zip code doesn't work for all countries.

But just for reference, in Singapore, we use 6-digit zip codes, each of which can uniquely locate a single building, so yes, a lot of local websites essentially just expect a zip code plus unit number, without the hassle of typing out the address at all.

Maybe what I wanted to say is, the idea is cool and _can_ work to enhance user experience with proper localization.

True. But this only mitigate the problem, doesn't solve it. Whatever BINs they use, there must be some noticeable patterns, simply because these cards are NOT regular cards.
