+title: hello
+date: 2026-02-26
+---
+
+i've always had some sort of homepage. it was originally on bebo, then that died and i didn't ever get into other social media, so i made a website
+
+i kept my last site updated for years, but every time i updated it i also ended up tacking on features i liked, and ultimately it became a mess. over the last year or two i spent more time fixing issues rather than doing anything that was actually interesting to me, so i decided it should be put down in favour of a fresh slate
+
+this site is very simple and i've set myself some arbitrary rules for it. i've been doing a lot of php lately and there's been a lot of search param usage there, so i'm using that here. instead of lots of different routes, i want to have as few pages as i can possibly afford, and anything else has to be done through search params
+
+in terms of routes: there's one massive [index](https://wynne.rs) of everything on the site, and each bit of text gets its own page
+
+:right[anything that takes more than a few seconds to read gets a proper page, and the short stuff, like my [cv](https://wynne.rs/cv.txt), is just a plain txt file]
+
+right now, *just* and *has* are params for filtering—[?just=guestbook](https://wynne.rs/?just=guestbook) hides anything not in the guestbook category, and [?has=hello](https://wynne.rs/?has=hello) hides anything not including "hello"—and *do* does some kind of one-off action, like [?do=random](https://wynne.rs/?do=random) which takes you to a random page or [?do=newest](https://wynne.rs/?do=newest) to go to the newest addition
+
+:left[the [manpage](https://wynne.rs/man.txt) exists as an up-to-date reference for search params and their usage]
+
+and that's it. i don't need anything else to archive things i care about
+
+cheers,
+lewis x
