I was recently migrating a large amount of data off of MinIO and wrote some tools for it in case anybody needs that https://github.com/dialohq/minio-format-rs

We moved to Seaweedfs around one year ago and I couldn't be happier. It also fixed all of the performance problems we had on MinIO.

It is very useful for long lived (bidirectional) streams.

My friend and I used to build a cross platform UI library in OCaml called… brisk. We didn’t make it production ready so i am sure the naming is a coincidence https://github.com/briskml/brisk.

wczekalski — Tue, 23 Jul 2024 04:58:52 +0000

it simply stores objects as files on the disk. Then it distributes the chunks around the place (so you need to reassemble it when reading) and lastly, when you read the file, it's not O(1). There is some "discovery" process to locate the objects where the servers chat with each other rather than have the location stored somewhere and be O(1).

Loki is not bad but PSA, don't use it with anything else than real AWS S3. The performance with Minio is awful (and can't be good, because of how minio works). Might be a bit better with Seaweedfs.

What's your basis for the claim that they are based on TorToiSe? I have seen this claim made (and rebutted) many times.

One thing I've seen done for style cloning is a high quality fine tuned TTS -> RVC pipeline to "enhance" the output. TTS for intonation + pronunciation, RVC for voice texture. With StyleTTS and this pipeline you should get close to ElevenLabs.

have you tested longer utterances with both ElevenLabs and with StyleTTS? Short audio synthesis is a ~solved problem in the TTS world but things start falling apart once you want to do something like create an audiobook with text to speech.

It depends on hardware but IIRC on V100s it took 0.01-0.03s for 1s of audio.

I use nix to setup the python env (python version + poetry + sometimes python packages that are difficult to install with poetry) and use poetry for the rest.

The workflow is:

  > nix flake init -t github:dialohq/flake-templates#python
  > nix develop -c $SHELL
  > # I'm in the shell with poetry env, I have a shell hook in the nix devenv that does poetry install and poetry activate.

I just thought about writers being able to share things they find interesting from other writers with their audience as an interesting lead.

Also an emergence of a "curator" class, people who could assemble "newspapers" out of the newsletters could be interesting, too.

ARM 32 bit is supported by OCaml. Just not for iOS/MacOS since the 32 bit iOS devices are ancient by now.
