      most of the things i find on the smallweb (gopher/gemini) stopped getting updates around 2021/2022 - did these protocols sort of die around then?&lt;br/&gt;or; did the newfound interest in them die around that time?

      whats a decent laptop for around 500 € ? used laptop recs also welcome :)&lt;br/&gt;&lt;br/&gt;(background - my thinkpad x220 hinge snapped in half and the chassis in general have been falling apart, so i prefer sturdy construction)

      In reply to &lt;a href=&#39;/nevent1qqst9ndcycy47ujmxjgatzt6sjuh6hxt82cj84tslgp4y2rcqpgjg6gjdw9rx&#39;&gt;nevent1q…w9rx&lt;/a&gt;&lt;br/&gt;_________________________&lt;br/&gt;&lt;br/&gt;ah, yeah shorting fractions isn&amp;#39;t necessary, it&amp;#39;s just that by their definition, a fraction (np)/(nq) = (mp)/(mq) for any n, m. this allows shortening, but doesn&amp;#39;t require it, like you note. if you&amp;#39;re ever curious, i&amp;#39;d recommend taking a look at the constructions of our numbers (ℕ, ℤ, ℚ, and most importantly ℝ) at some point! you already know ℕ from the peano axioms but it gives a lot of deep insight into a lot of mathematics rather quickly :)
