This comment shows what is wrong with people's understanding of futures markets. Commodity futures are not for the supply of commodities. If you need a supply of commodities, cash contracts are your thing. Futures, specifically, are us

What does it even mean to "output pixel"? The SVG format can be displayed with pixels, as can TARGA, JPEG, PNG, PostScript, and many others. Which format do you expect it to do, and why is that specific format the benchmark? Did y

Interesting. I tried this with 3.5 Sonnet and it got it on the first attempt, using CSS transformations to specify the angle of the hour hand. It failed, even with chain-of-thought prompting, when I asked for an SVG image, because it didn&#

> no downtime except when it restarts for updates. This sounds a little like saying "all of North America except the U.S." I don't think people are worried about random breakdowns on a single VPS, but scheduled updates are

This sounds vendor-specific and not general for Android. I've never had that happen on any device but Windows and I would be very upset if it did happen.

I prefer these days, when the absolute amount of information like this is higher, even if there's also higher amounts of junk. I can just not look at the junk today, compared to 25 years ago when the information I wanted only existed i

If that is what you want to do, you can do that in any language. It's just that when you do it in e.g. Java, you have to spend a lot longer proving correctness before discovering that it doesn't work.

Yeah, just last week I updated the numeric precision of a value across an entire user journey in a big enterprise application, spanning many functions and data types. Thanks to Haskell, I could do it in a day. In any other language I'v

No, that has nothing to do with it. Trivia helps you narrow down an interval. It is not necessary to construct a correct interval, which can be of any width.

Oh, maybe it's performing more complicated interval arithmetic. I had no idea. That's kind of cool!

The calculator cannot know whether there are no negative terms. For example, if people's net worth is distributed 0.2–400, there's likely a significant chunk of people who are, on the whole, in debt. These will be represented as a

The calculator in Emacs has support for what it is you request, which it calls "interval forms". Interval form arithmetic simply means executing the operations in parallel on both ends of the interval. It also has support for &quo

This looks like a much more sophisticated version of PERT than I have seen used. When people around me have claimed to use PERT, they have just added together all the small numbers, all the middle numbers, and all the big numbers. That resu

Sorry, my comment was phrased confusingly. Being overconfident with error bars means placing them too close to the point estimation, i.e. the error bars are too narrow.

Oh, this is very similar to what I have with Precel, less syntax. Thanks for sharing!

I have no familiarity with blue whales but I would guess they're 1--5 times the mass of lorries, which I guess weigh like 10--20 cars which I in turn estimate at 1.2--2 tonnes, so primitively 12--200 tonnes for a normal blue whale. Thi

It is producing a useful number. As more truly independent terms are added, error grows with the square root while the point estimation grows linearly. In the aggregate, the error makes up less of the point estimation. This is the reason Fe

I have made a similar tool but for the command line[1] with similar but slightly more ambitious motivation[2]. I really like that more people are thinking in these terms. Reasoning about sources of variation is a capability not all people a

"What would it take to convince you otherwise" is a question I've asked in the past, but I'm less and less convinced of its utility. If the counterparty knew the answer to that, they would sit down with Google, not engag

What makes you say they still totally depended on it? I can easily imagine groups of humans having a period of settled agriculture for convenience rather than necessity.

I don't remember the details of their arguments, but Graeber and Wengrow think this is a misleading image. IIRC one of their main thrusts was that over long periods of history, groups of humans have adopted and abandoned stationary agr

This is a common misconception. Lenses (or more generally optics) are not limited to targeting single fields. They can target composites, alternatives, etc. They go way beyond a normal accessor dot and can do stuff that cannot be done in ma

Basic string search and indexing operations (especially when there is language/library support for cheap spans) are definitely underappreciated. I wouldn't reach for them as a first step though, because they'd take more auto

I think GP was sarcastic. We have these great technologies available but people end up using duct tape and hope anyway.
