NiceMicro<a href="https://fosstodon.org/@25admins" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@25admins</a> I generally like to point out when people incorrectly call something that is "big" as "exponential".In today's episode <a href="https://fosstodon.org/@jimsalter" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@jimsalter</a> and <a href="https://mastodon.social/@allanjude" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@allanjude</a> almost called technical debt "exponential", but then they decided to say "compounding", which is funny, because "compound interest" is the type of change that IS exponential 😂 Exponential growth is when same interval -> same ratio of change. Exponential is not "big". A constant 0.1% interest rate is also exponential.<a href="https://fosstodon.org/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://fosstodon.org/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a>

PatI've made a fraction-based calculator, for simplifying rational expressions (written in ANSI-C using vi)I was aiming to merge a scientific calculator with "bc", because I often need to simplify various fractions and whatnot. Quite happy with the result!Uses shunting yard algorithm to evaluate the expressions, and a naive descent parser (I think?) to tokeniseAside: OpenBSD's "editline" is very easy to usePlease ask any questions :)<a href="http://patpatpat.xyz/data/frac" rel="nofollow noopener noreferrer" target="_blank">http://patpatpat.xyz/data/frac</a><a href="https://mastodon.sdf.org/tags/c" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#c</a> <a href="https://mastodon.sdf.org/tags/bsd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#bsd</a> <a href="https://mastodon.sdf.org/tags/unix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#unix</a> <a href="https://mastodon.sdf.org/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a>

paigerdutylast night I went on a wiki walk starting with Donald Knuth's impressive body of work and the title of his novelette "Surreal Numbers" piqued my interestthis led me down a delightfully confusing but fascinating peek into the weird side of math ft. The Monster, Baby Monster, magic squares and phrases that cracked me up like "weakly inaccessible cardinal"def gave me a new perspective on cardinality which I mostly deal with in the practical sense with system telemetry 😅 <a href="https://hachyderm.io/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#math</a> <a href="https://hachyderm.io/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mathematics</a>
