Hi all – You might find Charles Bloom's recent posts interesting, especially his intro to RAD's Hydra, a "meta-compressor" that makes block-by-block decisions on whether to use Kraken, Mermaid, or Selkie depending on user-specified tradeoffs for size vs. decompression speed.
He also has some fascinating posts on strtod, some low-level features Android needs to add to help performance-critical developers, paging and block size tradeoffs, his creative process, etc.
I always enjoy his posts – he's a righteous dude. But I'm not sure if people know where to find his posts. The complication is that he has two blogs:
The Blogspot blog has only seen one new post in the last eight months, something about a Nintendo "Switch" (I don't know what that is).
Everything I mentioned above is at his paleoblog, which has seen many posts in the last two months, so I guess that's where he puts most of his work these days. I'm calling it a paleoblog because the whole blog is just one giant HTML page, with distinct posts marked only by bolded titles/headings. There's no way to link to specific posts – the posts don't exist as separate pages or URLs. You just have to scroll down.
(FYI, his units are sometimes screwy. He'll use mb and MB interchangeably, and I think mb always means MB to him. If Kraken was really only decompressing at 1,000 mb/s, it wouldn't be exciting to anyone, so that's why I assume he means MB/s.)
