Types don't make testing in general unnecessary, but it removes a class of error handling that runtime type checking handles for you. You can really trust the types when using Sorbet.

(I also work in a 40m+ loc non-rails ruby codebase that is almost entirely typed with Sorbet.)

The "closed duplicate" thing is blown away out of proportion than it actually is. I'm convinced people are just pooping on Stack Overflow, not because it's bad, but because they just like complaining about things.

out of curiosity, why are you trying to validate emails?

I really enjoyed this read, thanks.

In the footnotes you said:

> One complication is that the counters have an "anti-tearing" feature for additional security

Two questions:

1. Why is it a "complication"? Is it just that it makes the counters more complicated, or is there something frustrating about the counters? 2. I would love to learn more about how the anti-tearing feature works!

Sure.

The post mentions BYOIP. I assume Cloudflare wanted OP on BYOIP to mitigate risk, and Cloudflare wanted them to pay for the privilege.

I don't think spammers care if trimming the plus-alias doesn't work for some email providers.

Gmail is also pretty popular, so it's not much work to just hardcode it there.

Knowing that a guy wrote this ruined the post for me.

New comment by qaisjp in "Why does sleep become more elusive as we age?"

qaisjp — Sun, 03 Dec 2023 23:33:54 +0000

25 and struggling with this.

I was feeling motivated last night at 1am, and it took every inch of my body to NOT whip out VS Code.

Still couldn't sleep until 4am. Woke up today at 1pm.

I used to think that growing up would mean that I could go to sleep whenever I wanted, and do what I want.

Turns out that growing up means you learn that you shouldn't do those things.

But why? My mornings are usually clear of meetings, and I could just work PST hours from the east coast, and it would be fine.

Turned out that working every evening is not good for your social life, and having a social life is something I try to prioritise more than hacking all day all night.

This is so wise. I'm gonna ask my teammates next week about what it is in their job that they give a shit about.

New comment by qaisjp in "ChatGPT’s system prompts"

qaisjp — Sat, 14 Oct 2023 20:06:24 +0000

I haven't played much with it recently but I was under the impression that ChatGPT was not great at mathematical computations.

that's to say, 1+1=2 is a well known fact, so it'd get that right, but ask it to md5sum a string that is not in any existing rainbow table, and it'd get it wrong.

I've not used GPT 4 so it might have gotten better.
