Maybe I’m missing something but can’t you unroll it very easily by 15 prints at a time? That would skip the modulo checks entirely, and you could actually cache everything but the last two or three digits.

Sure, 3 x 5 = 15. But, FTA:
But then, by coincidence, I watched an old Prime video and decided to put the question to him: how would you extend this to 7 = "Baz"?
He expanded the if-else chain: I asked him to find a way to do it without explosively increasing the number of necessary checks with each new term added. After some hints and more discussion...
Which is why I respectfully submit almost all examples of FizzBuzz including the article's first are "wrong" while the refactor is "right".
As for the optimizations, they don't focus on only 3 and 5, they include 7 throughout.
The only thing I see is:
Safari can't open the page because it couldn't establish a secure connection to the server.
Add "webmasters" or "sysadmins" to the list?
// An eighth reload worked.

This is baby tutorial level.
Look into iOS device management.
Let users let you manage the device.
If they don't put it back in their pocket, wipe the device.
Yeah.
They can restore from iCloud, but come on.
You talk big talk, be big stick.
Paper: SlowFast-LLaVA-1.5: A Family of Token-Efficient Video Large Language Models for Long-Form Video Understanding:
“We introduce SlowFast-LLaVA-1.5 (abbreviated as SF-LLaVA-1.5), a family of video large language models (LLMs) offering a token-efficient solution for long-form video understanding... Experimental results demonstrate that SF-LLaVA-1.5 achieves superior performance on a wide range of video and image tasks, with robust results at all model sizes (ranging from 1B to 7B). Notably, SF-LLaVA-1.5 achieves state-of-the-art results in long-form video understanding (e.g., LongVideoBench and MLVU) and excels at small scales across various video benchmarks.” -- https://arxiv.org/abs/2503.18943

> If you are a heavy user, you should use pay-as-you go pricing
if you’re a heavy user you should pay for a monthly subscription for Claude Code which is significantly cheaper than API costs.
Define heavy... There's a band where the max subscription makes most sense. Thread here talks $1000/month, the plan beats that. But there's a larger area beyond that where you're back to having to use API or buy credits.
A full day of Opus 4.1 or GPT 5 high reasoning doing pair programming or guided code review across multiple issues or PRs in parallel will burn the max monthly limits and then stop you or cost $1500 in top up credits for a 15 hour day. Wait, WTF, that's $300k/year! OK, while true, misses that that's accomplishing 6 - 8 in parallel, all day, with no drop in efficacy.
At enterprise procurement cost rates, hiring a {{specific_tech}} expert can run $240/hr or $3500/day and is (a) less knowledgable on the 3+ year old tech the enterprise is using, (b) wants to advise instead of type.
So the question then isn't what it costs, it's what's the cost of being blocked and in turn blocking committers waiting for reviews? Similarly, what's the cost of a Max for a dev that doesn't believe in using it?
TL;DR: At the team level, for guided experts and disbelievers, API likely ends up cheaper again.

In my use it feels as though this should not be done in advance or in the same prompt, even with reasoning models. It'd be better to make a "double check" MCP that calls your prompt, asks whether anything should be amended in that reply or use as is, amends if needed, then gives answer.
What you do not want to do is reposition your context into under-informed persona space, so leave the second-guessing out of the initial context. Instead use it as its own judge. (Doesn't have to be, but could also be an alt model.)
If I'm not allowed to develop and install my own apps on my own phone, what advantage does Android have over Apple?
I find it easier to do a git commit once every 89 days and see my app auto refreshed through Testflight for me and anyone else I care to let use it.
If you look at the build system SaaS pricing or even IDE pricing on Show HNs here, the Xcode cloud build and distribution ecosystem is an absolute steal at $9 a month. Private Testflight (with no review) can be more convenient than that desktop cable.
