In the UK,the value of student debt is explicitly estimated to take account of this and other factors, and has been for years: > The Government expects that around 27% of full-time undergraduates starting in 2022/23 will repay them

Can anyone explain how wages can possibly be this high? Why doesn't everyone on a low income want to become a UPS driver?

I find chatgpt quite good for this. Often purely the exercise of trying to phrase the question leads to clearer thinking, and chatgpt makes pretty good suggestions too

One super useful and often overlooked feature of vega lite charts is they embed the data within the chart definition. That means you can easily extract the raw data. You can also easily change the visual appearance or chart type by opening

About 500k people die in a normal month in Europe, so it doesn't seem completely implausible

Most of the time I agree, but if you want to e.g present a tutorial as a webpage, having an ipynb with both inputs and outputs becomes a feature. You can even bundle into docs e.g. https://moj-analytical-services.github.io/

There's a big performance difference between creating the Cartesian product and then filtering for the conditional, and creating the conditionals directly. An inner join with equi join conditions creates the conditions directly; any n

Interesting - so presumably you could also make a small amount of money by turning on e.g. a bunch of electric heaters. Makes me wonder whether someone could (or is) making significant money this way. It's amazing to me there isn&#x27

It was because the wind was blowing and solar was doing well. At 14:30, wind was 15GW and solar 7GW against demand of 28GW. Nuclear was an additional 5.3GW. See https://grid.iamkate.com/ . I don't know the specifics of

I think the fundamental issue is that a single 'cell' (value) can contain newlines, so you can't just assume each line is a 'row' and trivially parallelize. The problem is perhaps most obvious when you consider that

Whether you agree with him or not, the argument is more nuanced. I believe the relevant section is page 169 of this: https://www.stafforini.com/docs/Singer%20-%20Practical%20eth... Some of the text is copied and pasted

For straightforward analytics queries, 20gb is well within what is possible to process on a single well specced machine. I would recommend storing the data on disk in parquet format and taking a look at duckdb or polars for processing it. O

Economist here. Imo the market rate would be the price at which supply and demand were equal. In this case, the government should choose the supply such that it's ecologically sustainable. So the price is the price at which that susta

Many reactivity frameworks (e.g. observablehq, shiny) recompute intelligently - they're aware of what parts of the calculation has changed and needs recomputing. Haven't checked with ipyflow, but this idea would help mitigate som

With all the hype about AI this year, does anyone know whether it's translating in any meaningful sense into self driving? Can they use transformers? If so, is there a step change in performance? Has this already happened?
