Ask HN: The Importance of the Set {-1, 0, 1} and it's Universal Application

Hacker News - Tue, 09/10/2024 - 10:31pm

The set of integers {-1, 0, 1} seems to pop up in a surprising number of contexts.

-1: The idea of negation or taking a step back. 0: The neutral point, the absence of something, or a starting point. The singularity. Absolute 0. The origin plot on a number line. etc. 1: AKA +1: The building block, the single unit from which we construct. Represents the smallest possible unit of any measurement (1,. .1, .01, etc). Rather than posit my own ideas and applications here in this OP, I am more interested in generating discussion here on HN and getting input from those with more knowledge and expertise in the area of mathematics and sets, and their various applications.

What would you say about this set either exclusively within mathematics or applied to any of those other fields of study which intersect?

Show HN: AI Hug – The 6th Website Built by a Newbie Developer

Hacker News - Tue, 09/10/2024 - 9:55pm

----Background----

I'm primarily a tech support guy, originally with no connection to development. But in the last couple of years, AI has advanced so rapidly that even a novice like me can leverage its power to build websites.

Due to economic pressures lately, I've been exploring ways to make money overseas, which is why I'm learning web development.

This site is my 6th project. Of my first 5 sites, three were built with WordPress, which didn't really involve much development. The fourth site was made using JS, HTML, Tailwind, and Cloudflare, but as a practice exercise, I only created a simple static page.

For the fifth site, I jumped straight into using the trendy Next.js framework. With the help of third-party APIs, I built a site for automatic image expansion. However, it hasn't gained traction yet. Oddly enough, despite adding many backlinks, only the one from a site was picked up by Google Search Console.

----Main Point----

After reviewing my experience with these previous sites, I've realized that it's not necessary to develop all the features before launching. Instead, it's better to start with a landing page, focus on SEO, and then develop additional features once the site's Google ranking improves. With my previous site (https://aiexpandimage.org), I finished the landing page in just a few hours, but spent a good week or two developing the features.

Currently, the average Google ranking is around 64, so it'll take time to gradually add backlinks and promote the site.

I've wisened up now. For my new site (https://ai-hug.org), I've only created a landing page. I'm focusing on SEO first, and I'll develop the core features and payment system once the traffic starts coming in.
