I think Renewables (especially solar) tend to be fairly easy to cutail (stop generating) and can probably avoid generating much during negative prices. I'd guess the negative prices will probably mostly hit legacy assets that don'

Gas plants can't really change how much they are generating in seconds. What they actually do is use the inertia of the spinning machinery, when the grid frequency drops (which is usually one of the first symptoms of load exceeding dem

I like that analogy. Batteries are kind of the RAM/cache in the system: - Big merchant batteries like Hornsdale are kind of like more distant ram RAM - Batteries co-located with renewables are kind of the local to core ram - UPS and s

The nice thing is as long as these markets stay reasonably competitive, economics can figure out what to do with excess renewables. When renewables are in excess, the spot (instantaneous) energy price will drop to near zero (or sometimes ne

Glad to see this finally happening. This goal was definitely part of the appeal when I was working on the Autobidder team at Tesla! The regulations have some work to do catch up to allowing batteries to operate in a straightforward manner.

Sorry it took me a few days to see this. Right now we have trust per person, and a separate "preference" by topic. Our end goal is to do trust per person per topic.

Sift ( https://sift.quest/ ) is working hard on doing exactly that. We don't have enough users to actually show it off yet, but at our core we're building around a user reputation/relevance graph that we think

We don't have a community yet, but sift ( https://sift.quest/ ) is aiming to be a comprehensive alternative. We've got some new ideas around dealing with cross posts: * posts can have multiple tags and be findable

Thanks the feedback! * Yes, we are working on comments sections for posts. Hoping to deploy this week. * Usernames on posts are coming soon. They interact a bit with some things we are doing differently at Sift, so there's some complex

We're still pretty alpha, but Sift is aiming to hit what you are looking for https://sift.quest/about We ended up launching sooner than we really planned after a reddit post last friday got more attention than we expec

Light actually has momentum but not mass. Calling it effective mass isn't far off, but sometimes my pedantic physicist kicks in.

Writing the 100 page thesis is not the hard work part of a PhD. Doing the research to have the results to write that thesis is the hard work. Unless you are uncommonly lucky, you will fail at some avenues of research and have to slog throug

I use spacemacs and want to play with the vim part more, but I type dvorak, so I wanted to do a similar remapping and remap hjkl to htns so I would also be curious to hear if anyone has a good way to do that.

Bayesian Logical Data Analysis for physical scientists by Phil Gregory is pretty good, particularly if you are some kind of scientist. source: I TA'd a course in Data analysis, primarily bayesian, that used that as the textbook.

Looks like pypy for python 3 is back on track. This ameliorates one of my concerns about migrating to python 3 since I think/hope that pypy is going to be an important part of future python.

I have been thinking about building something to implement something fairly similar to what you described there. If you want to chat more, my email is in my profile.

The work is being done by my labmates, so I can answer questions. The killer application here is color e-ink displays, since these structures are purely reflective, they should let you make an apparently brighter display by sending back all

Yes, we do have some pretty good theories for designing metamaterials. From what I can remember (and quickly look up on the net), one of the leading theories is called transformation optics, and finding a coordinate transform to a coordinat

Yes, I would be more likely to play in Python, though I guess I do need to bite the bullet and learn javascript at some point. If you can integrate haste or fay and let people play in Haskell that would be indeed be epic, and I would defini

You might also think about putting it on the arXiv (arxiv.org). I think they take articles that haven't been submitted to journals, and it is a bit of a recognized source of articles (there are citation guidelines for arxiv articles fo

Amusing anecdote: I was at a pg talk last week, and afterwards someone in the audience came up and asked if SR being gone meant there was a market niche for a new startup. pg's answer was that it was in no way worth the risk, there are

I don't buy books to look good for my peers. I buy books because I like reading them, lending them, etc. The social signalling is just a side benefit.

Plus, walking into someone's house and seeing a bookshelf full of awesome books is a good way to know that I am probably going to like said person.

A less centralized version of that would just be to make it really frictionless to resell things. So when I need the drill for once in a year, I pop uberlocalbuy, buy a drill from someone near me and either pick it up or pay for delivery.

Wow, I didn't realize they went that high. Then yes, with the current output of a battery pack, I can see why people are worried.
