Interesting article, but it should be noted that there is no "official name in English" in any meaningful sense of the word. Yes, you can cite what a particular government entity uses, but unlike French, English is not an official

Where's the live online demo where I can upload something and watch it work? Without that I have no confidence that the system actually works. [EDIT] Sorry, missed that!

The problem with your reasoning--and it is exhausting that society seems to need to relearn this every generation--is that this is not about what standard you think is reasonable. It is about the granting and exercise of power. Once the pow

This study is not a randomized controlled study and it lacks even modest efforts at statistically controlling for confounding factors. It is therefore not possible to draw any meaningful conclusions from it. It appears science education is

You present a plausible conceptual model of the core principle of a greenhouse gas. There are numerous questions between your conceptual model and explaining what fraction of the observed warming can be attributed to that effect. What other

Respectfully, you are missing the point. The claim being tested is whether humans caused climate change, not if they increased the CO2 concentration in the atmosphere. Explaining the relationship between the two is point of the model and ca

Skepticism doesn't require being supported. It is the default perspective when facing a scientific assertion. Conversely, affirmative scientific assertions require the support of relevant reproducible facts. Appeals to authority or con

The same approaches and models that are used for predictions are used to establish the attribution of cause. But while the latter cannot be tested, the predictive power of the models can be tested and is thus a suitable proxy for the power

That is a high level of consensus for a field where the predictive models (which have been getting published since the 1980s) are extremely bad at predicting the future. Last time I looked into it was about 10 years ago, but at that time, t

I was the one who devised those labels and it was hard to come up with the words to describe the temperature ranges (we also report the raw temperature range for each category, so you can remap the words as you please). I did my best, looki

My main technique from my engineering undergrad days was extremely effective and yet very simple and easy to describe and/or implement. It is: 1. Attend the lectures and take good notes. Don't write things down that are obvious or

I am the original poster. The purpose of the post was to get the issue fixed (since support gave me the run around). Now that it has been fixed (and confirmed), I have updated the post to reflect that and have hidden it (as it is no longer

I’m one of the developers. This tool makes it possible and comprehensible to interactively explore visual datasets with millions of items. It is a pan/zoom interface showing an irregular grid of images. The items are organized using ma

Your second rank ordering chart, the one by the upper bound of Rt, is deceptive and misleading. North Dakota and Arkansas only have a high upper bound because there are so few cases that the uncertainty is high. That chart and any analysis

Do you have a private office at work? It is like sitting in the same pod as a teammate. But I agree you wouldn't want it with a wife and girlfriend. Could get awkward with them both there.

We used Squiggle for a little while and really really wanted it to work for us. But the audio and video quality (and connection reliability) was just not nearly as good as FaceTime, and we were/are a two-man team, so we just switched b

Just click the "View" button on each result and you get a full featured viewer with pan/zoom, quick toggling from before/after, and even a heat map showing where there are big differences between the two.

I'm the other developer. There is actually some pretty cool math behind this: The underlying algorithm has not been published. At its core is a color median filter, a block-L1-minimizing generalization of the well-known scalar median f

I wasn't referring to efficiencies. I was referring to dollars per unit of energy, as paid by the end consumer. That "study" explicitly says it didn't take that into account. Electricity is expensive, as anyone who has e

by jrd79 8y ago
But isn't electricity much more expensive per energy unit than natural gas? I don't have an ax to grind on this, but it seems like comparing apples to oranges if cost is a concern (which it may not be).

Thanks. You seem to be spot on about the HN community not finding this interesting. We've announced a number of projects on HN over the years and while I didn't think it was a slam dunk I did expect a better reception than this. O

The PNG code is based on UPNG.js, the SVG is based on SVGO.js, the JPG is based on MozJpeg (run through Emscripten), and the charts are done with Chart.js. The rest is just some web workers, the UI code, and a small quantity of HTML and CSS

You can always save a Chrome shortcut to your desktop, but the app is entirely serverless javascript, so making a desktop app would be not much more than that, but with the disadvantage of not getting the Chrome updates.

Hi, I'm the author of this tool, happy to answer any questions. Built it to get more nuanced insight into the per-image tradeoffs at varying levels of compression, and to get something that supports SVG. Most of our assets are SVGs the
