The various personal freedom takes on regulation like this seem ring hollow. Regulations like this impose constraints on economic and commercial activities, not personal ones. No one will be prevented…

If your smart contact is truly reliable and anyone can lend on it at a rate of their choosing, and all loans are fully and perfectly collateralized, the natural interest rate is exactly the risk free …

Rates are lower on margin loan, and they’re easier to get compared to a proper mortgage (assuming, you know, you have value assets to borrow against)

Since ETH staking returns do represent a (sort of) risk free rate for ETH denominated loans, low fiat rates would pull down on those rewards, if the exchange rate volatility comes enough for people to…

Exactly. With the slight caveat that beautiful and scenic really only enter into your triangular choice when a place is publicized (advertised?) as such. There are beautiful, restive, empty places t…

They do? TFA says as many as half they techs are FTE. The alternative is not that they hire everyone as FTE, its that they hire and fire FTE to meet their labor demand, and then we get lots of doom an…

OTOH, security researchers do inflate the value of any given exploit (chain) vs. broad mitigations. Still, 200k seems _low_ for a bug that should imperil the reputation of a many-billion dollar compan…

I’d argue the counterpoint actually: Writing Makefile targets for common commands significantly improves usability and ergonomics, especially when they follow common idioms (make test, make build, mak…

One perspective from this thread: environment variables end up denoting different levels of persistence in interactive, server, and containerized applications. For interactive apps, environment varia…

If The same pattern works well in python at the module level, if your application is setup as a package. A module config.py sets a bunch of python variables like import os ENV_VAR=os.e…

I'd venture a guess that anyone advocating REPL-based development in Python is pitching IPython/Jupyter. IPython's REPL supports multi-line editing, trims common leading whitespace fro…

Lots of comments assailing this approach as a poor replacement for monitoring miss the point. Of course monitoring and proactive repair are preferable - but those are systems that can also fail! This…

It’s a terrible point that the graphic doesn’t support in the slightest. But to answer your question: IC engines are energetically inefficient - at best a large fraction of the input potential energy …

For one, traditional finance has the NBBO requirement. Regardless of how an order makes its way to to a broker, they can’t execute at a worse price than is available. Payment for order flow (at least…

A thought: presumably the institutional investors are going to be both better equipped and more eager to extract money owed to them, whereas a SaaS business is more likely to cut losses, offer discoun…

Didn't realize duckdf was your package. Cool! Definitely something I'll consider for future work, though I spend more time on the Spark-and-Python side of the fence these days. If you want…

I think the point from GP (which aligns with my thinking) is that more programmatic interfaces for querying data allow for control flow in constructing the query, not just in processing it. So you ca…

While sqldf has been around for a while, it's not been a performant choice, since it requires transforming and moving data into a database, albeit one that's in process. So with something l…

I think the answer to your question is that, until relatively recently it was not possible to run arbitrary SQL against data frames in either language. sqldf and duckdf pass data off to another progra…

I suppose small investors could realize the same diversification by lending in very small amounts to a very large number of borrowers, such that only a small fraction of their wealth is exposed to any…

Big institutions make the loans because small ones can’t bear the risk. A small investor might only have the capital to make a handful of mortgages, and so have a much higher variance in her outcome.…
