Didn't the Fed say it will buy up to $500B of municipal bonds as part of the new QE program?

I wonder if the "Lottery ticket hypothesis" work can be applied to this model to further shrink the number of parameters by 10x, to bring it closer to Google's T5 but with higher accuracy?

Slick! I too felt that many libraries were not slick/fast enough, but I eventually ended up using react-stockcharts (in canvas mode) for my use case and was quite satisfied with its performance. Could you compare your performance agai

As others have noted, Q2 would likely be worse hit than Q1 since the quarantine started later in the quarter. FRB NY has a GDP Nowcast prediction of about -8% for Q2.

What is the recommended best practice for a stable API endpoint that supports things like filters, pagination, and some limited aggregation? Would a REST-like endpoint backed by a database VIEW (to decouple schema changes from API changes)

Try the paper towel trick: wrap the seeds in a moist paper towel (not too wet, or it will encourage fungus growth). Then, keep them inside a ziplock bag in a warm place for a couple of days, checking on them every day. I keep them on top

Yep, that's right. Its cardinality is the same as rationals, since it's countable.

I think this is a very important area with applications to legal issues; in the computer systems domain, a close application I can think of is troubleshooting / root-cause analysis. In legal situations and troubleshooting alike, one is

The distinction serves a real and practical purpose, as mentioned in the introduction: responsibility/blame assignment. In legal situations, this blame assignment is critical as it helps identify who is actually responsible for some ba

It's a funny coincidence that I was just reading this book ( https://toc.cryptobook.us/ ), Figure 4.5 on book page 102, that talks about this exact issue. I doubt the author realises that the system must be resistant aga

The analogy is a bit extreme, don't you think so? Isn't there a difference between developing a technology and actively taking part in selling it for a use-case that you disagree with?

There's an interesting podcast where Philip Goff and Sean Carroll discuss about various aspects of panpsychism. Sean plays a very good devil's advocate, so if you enjoy a nice friendly critic of the above ideas, I highly recommen

How enormous are these pension fund liabilities? Looking at the balance sheet of GM, their last annual pension fund liability was put at $18B, roughly 10% of their total liabilities. It doesn't seem much and probably shouldn't f

Yep, that's the underlying principle behind Mellor-Crummey Spinlock: https://lwn.net/Articles/590243/ .

Aren't most modern spinlock implementations are ticket-based, which ensures fairness among waiters (FIFO-like)? The linux kernel implementations most definitely are. I agree that the naive implementations are not.

Interesting. Wouldn't existing intrusion detection systems fire alerts on seeing random DNS queries from a host to `domain.tld`?

That points to the core of the issue. "Fairness" in ML algorithms can be hard to define and assess. It's easy to say "omit gender from the model", but the real issue here has to do with the _causal_ pathways betwee

One of the best explanations I've read on this is here: https://www.reddit.com/r/Economics/comments/d6e8qv/the_fed_p... . Although, I must admit I don't understand the carry-trade dynamics that

One of my professors used to say -- Writing is to thinking as alum is to murky water. Indeed, writing makes you crystallise your thoughts.

I think you meant to say -- Type 1 is a false positive, and type 2 is a false negative.

Great summary. I also love Prof. V. Balakrishnan's exposition on this topic. The video is long, but he motivates the ideas very clearly and in context: https://www.youtube.com/watch?v=GOkZs2RZMQY .

Yes, the claims are pretty much in the same spirit. Although the first (Weierstrass's) theorem [1] was stated for real-valued functions in a 1-D closed interval [a, b], Stone-Weirstrass is a generalisation of the above theorem [2] tha

This series is well written. The speed up is expected due because you're incorporating second-order information during the optimisation. For more insight into second order optimisation methods, take a look at Newton's method: h

No, that's not true. The insert function (hash, rbtree, etc.) takes a hash node as an argument. So, in the kernel implementation the caller is expected to hash. EDIT: check out some examples to see for yourself: https://el
