FOSS just does not have the aggressive scaling mindset. Even success stories like Linux' game compatibility and Chromium can be traced to just regular tech companies, as opposed to non profits.
Many non open source apps do get critical mass but they eventually go bust. Emacs, git, Linux and I think even Mastodon have a slower uptake but do not seem to have such a high risk of collapse. While YouTube and Facebook et al seem to have an insurmountable moat and collection of users the reality is recent history is littered with boom to bust failures:
MySpace, Vine, Yahoo all the way back to GeoCities.
I would be patient and only worry if mastodon is actively dying.
For me it's the only social media app I have installed.
I have both Mastondon and Bluesky accounts and in my experience I find Bluesky is just simpler to use which attracted more of the types of accounts I wanted to follow. Nothing aggressive about that, just good UX resulting in a richer pool of accounts.
It is quite remarkable just how frequently people in tech forums underestimate reasoning models. Same story on several large technology subreddits. Wouldn't have been my guess for who will get caught off guard by AI progress.
The least volatile dataset, employee count 1-4 businesses, is steadily climbing in adoption. I feel like as long as the smallest businesses (so the most agile, non-enterprise software ones) increase in adoption, other sizes will follow.
Vitess (sharded MySQL) is how they became relevant. But broadly they've spent a lot of time making a great DaaS. There plan is to do the same with Postgres.
Large latent flow models are unbiased. On the other hand, if you purely use policy optimization, RLHF will be biased towards short horizons. If you add in a value network, the value has some bias (e.g. MSE loss on the value --> Gaussian bias). Also, most RL has some adversarial loss (how do you train your preference network?), which makes the loss landscape fractal which SGD smooths incorrectly. So, basically, there's a lot of biases that show up in RL training which can make it both hard to train, and even if successful, not necessarily optimizing what you want.
They are PCB brands. The microcontrollers are made by the usual manufacturers like ST, Renesas, Infineon...
