I think this design is usually called a "scanning monochromator" - really nicely done.

1. The platform doesn't exist to do basic things like authentication or push notifications, so people hack together expensive cloud services or do insecure things instead. There is no rulemaking that will help this, we just need a bett

This result is not inconsistent with the "spend more time outdoors" advice. It's using visible red light that's very intense - more than we see indoors, and mechanisms as simple as "triggers dopamine release in the

This isn't how glucose rhythms work, and there is a new Current Biology paper to show the difference: https://www.cell.com/current-biology/pdf/S0960-9822(23)00144... https://scitechdaily.com/s

They sell 2.2M cars a year, so if 5 model years of cars are involved, that's >$2200 ARPU. This makes no sense at all. It's orders of magnitude too high. Some auto leases are about that much!

It's IP52 rated, so not water-safe like the IP67 and IP68 from other smartphones. But it probably costs less to fix even so.

Not a lawyer, but language like this is important. You should never represent that your software cures a disease or condition, or that it replaces a doctor (unless it's actually a FDA-cleared medical device). The general guidance from

Surely recruitment costs and CAC are a huge part of this business. You can't just make a two-sided market with all these things being free? What's important is that "local" seems to have gotten lost in the shuffle. Food

Updates on-device are also an essential technology. Many apps are hamstrung by delayed updates due to a policy change from the app store.

For sure, HDR and AI noise removal are pretty good. But there's one more thing that's less visible, which is that smartphones are not very friendly to standalone cameras. Cameras have always depended on PCs to do capture. And sinc

If you wanted to make app stores stronger and the Web much worse, these consent banners would be a fantastic way to do it. "User agents" should be able to express our intentions clearly and without nag screens every time.

You can check spot prices for NAND chips (Gigabits not GB) which explains the margins for end-user products. (This one is <2% of the TLC chip cost, obviously fake.) https://www.trendforce.com/price/flash

I love what they've done and how my kids have taken to it. The combination of design tools and code reminds me of the "golden age" of Flash in some ways. Vector graphics editor, sound editor, code, it all works together - thi

So... we are to believe that photographs are not biometric identifiers (they are excluded in the text), but photographs once processed with readily-available software are biometric identifiers? On the other hand, structured-light scans

I agree we are working through an asset bubble in tech and housing - P/E's went quite a ways above the historical line, as did housing prices. But think about the chip shortage (automotive, consumer electronics) - raising interest

They've identified several correlates due to weather (cloud cover, rain, wind, day length), but then I can't find where they correct for these in talking about effect sizes. All of these effects then "add up" to make the

2FA should never be vague - it should say "Don't give this code to anyone." People are getting scammed all the time this way.

That is one interesting study in mice, but it goes against many in humans, so I wouldn't use the word "debunked" in this situation. Previous comments are here: https://news.ycombinator.com/item?id=21916679

Thank you to this community for all the support through the years! We're spending a lot of our time on basic research and sensing, and we have a few small updates planned for f.lux, too. The main challenge as we learn more about the bi

What about readability? It's harder to read green bubbles and you can show it with accessibility metrics. If you think about luminance contrast, blue is much darker than green. So the blue bubble text is easier to read, because the tex

One thing here is that it suggests removing pure virtual functions with just one implementation. I use this pattern often to kill dependencies, say when one huge part of an app needs to call another one, but you don't want to create

This "lens brunescence" theory is very odd and likely wrong: lens yellowing does not impact the ability to distinguish blue from green under even modest illumination levels. While it's a substantial effect by age 90 [1], it w

I love this work - the OKLab model is really wonderful. But I think for color pickers, there are cases where "constant lightness" is not the most important constraint. For instance, you might really mean "the most saturated p

Before Chrome launched in late 2008, Google promoted Firefox as the browser to get. That changed when Chrome launched. It's amazing to read about things Firefox did "wrong" right after that in 2009 - correlation just isn&#x27

I benchmarked an Alpine's musl doing strstr with a 200-byte "haystack" with a 10-byte "needle" and it's 8x slower than Debian 10's glibc.

I think we need more well-maintained "parts" that can be used as alternatives to libc. For instance, string operations can be 5x faster on AVX2, but not every distro provides this code. I recently upgraded some Centos 6 machines (
