Experimenting with skip-lists for malloc today. With a first-fit allocator, free() wants to merge adjacent blocks, so it needs to search for them. A single-linked list makes that O(N). A skip-list seems like an interesting option—non-recursive, low memory use and simple implementation. It's "working", but it's not pretty yet. Anyone else ever played with these?

stdlib: Rough version of skip-list based malloc · picolibc/picolibc@029cc74
Replace the single linked list of free malloc blocks with a skip-list. This converts free from O(N) to O(log(N)) and might serve as an alternative to the bucket-based allocation scheme currently bo...

Hopefully, it's more of a midlife incident than a crisis, but this weekend I dumpster dived for 1,587 pounds of photovoltaics. Feeling a little sore. I hope 7.6W/lb isn't a bad deal. I'm still dismayed that the school district is just throwing them out.

Two more C23 math functions for picolibc, compoundn and pown. While doing this, I discovered that I'd used the wrong constant for Dekker's Split function for binary64 values. That took a while to find.
So far, my new 'math_two' environment is working out pretty well; it's pretty easy to write format-independent floating point code now.

These are from C23 and share a common implementation in _ff_pown.

@… won't get this but I do believe those #Nextcloud wss:// errors are mere warnings, however when I look at the console errors (which include the wss) I notice Social fails to read outside profiles from #mstdnca although I can see the profile on my local pixelfed and both social and pixelfed show these following each other, but even the local pixelfed gets no posts, and social sees the profile from pixelfed but no posts or messages.

Canada's last epishelf lake is gone for good, study confirms
Canada's last epishelf lake drained into the Arctic Ocean following the 2020 breakup of the Milne Ice Shelf and will not recover, a new study confirms.

math: Add sinpi/cospi/tanpi functions by keith-packard · Pull Request #1383 · picolibc/picolibc
The existing kernels start with two floats, so it was easy to use some new float-float helpers to compute the product of a double-precision pi and the parameter. These all generate results within 1...

I released picolibc 1.8.12 today. Thanks to all who contributed; I'm doing less and less of the work, which is fabulous.
