I love the note regarding the rearview mirror being an actual, you know, mirror.

A friend was teasing me the other day for using my mirrors while I backed up, ignoring the various screens and camera feeds dotting the dash. I reminded him that photons impinging my eyes reflected off the material world at the diffraction limit of the visible spectrum remain much higher fidelity than some shitty parts-bin screens.

Plus those rearview screens are always horribly bright. You know what has infinite levels of dynamic brightness? Light bouncing off a planar reflector.

So much of modern cars is cost savings and poor design decisions dressed up in the name of modern - but ultimately resulting in UX worse than an early 2000s Honda.

That’s great, unfortunately it is quite rare for CS undergrad programs in the US to require the basic engineering and science classes the other engineering/science majors require.

It is funny, almost as funny as an entire cadre of people with “engineer” in their title who've never had to draw a free body diagram, learn circuit analysis, understand the basics of thermodynamics, or the mechanics of materials.

It’s crude, but you can overcome the degraded quality imparted by gpu accelerated encoding by specifying a higher video bitrate.

Find a complex short scene in your cpu encoded video, extract it, ffprobe it to get average video bitrate, and take the same clip in raw and try gpu accelerated encoding at +20% bitrate. From there, iterate.

For a friend’s use-case that I helped with, +30% video bitrate bump overcame the degraded vquality.

Edit: strangely enough, if memory serves, after the correcting +30% was applied the actual ffprobe bitrates between the videos were very similar, maybe a 10% or less difference. Someone smarter than me can work that logic out.

AnandTech was one of the websites that helped me as a child. I found it around 2002, and the clear-headed manner in which it discussed chip fabrication, function, lithography and the associated engineering and scientific foundations of them - as well as general concepts of bios, motherboard, chipsets, slots, bandwidth etc - helped foster a curiosity and familiarity with electronic hardware that has served me well for my whole life.

It helped me dream larger than my surroundings; which in turn helped me get out of an unstable home, poverty, and a dead-end town. I was sad when [H]ardOCP went down, but this hits different.

fyi, if you're uncertain in the single-digits place, you have no precision in the tenths place. for experimental uncertainty, it's always one sigfig

I use Tree Style Tabs, yeah. This is how I like it configured, nice and tight: https://i.imgur.com/fWonbjC.png

To get it that way takes a bit of code in the advanced options, and tinkering with a user definition file in FF to remove the top tab bar, but it's worth it.

The other killer feature of FF for me is the ability to containerize domains and control how cross-domain containerization occurs (https://addons.mozilla.org/en-US/firefox/addon/containers-wi...). My interactions with google (for example) never leak out of my google container, so my search queries or browsing aren't explicitly linked to my google account, because I do that outside my google container. Want to watch a video on yt without it tanking your recommendations? Do it outside the google container.

Of course there are a lot of other ways for google to infer it's "me", so I don't know if this is pure security theater or it actually hinders them building my profile. Either way, it's nice to be able to explicitly determine when and where my google profile is built as I traverse the web.

On desktop, FF supports the best vertical nested tab tree I have seen. What I’ve seen on chrome is laughably amateurish with huge chunks of wasted space due to unmodifiable(?) padding elements

You shouldn’t approach it from such a detached, cynical angle. The import is as if the OSI embedded senior agents in the postal system during the labor unrest in the US during the 1910s-20s, and the FBI in Ma Bell during the second red scare in the 40s-50s.

The possibility for gatekeeping primary modes of information exchange is quite real, and quite worrying.

Exciting times! Any physicist here aware of how these two papers would impact the applicability or validity of Modified Newtonian Dynamics (MOND)?

background: my lay understanding of MOND is that it modifies the gravitational interaction parameter over cosmological distances. the force exerted on objects due to gravity is currently accepted to scale with distance in a certain manner (ex. 1/distance^2) while MOND postulates a different scaling relation (ex. 1/distance^3). Those are just examples, not actual values. The currently accepted gravitational interaction force scaling is what gives rise for the need for dark matter, and the corresponding lambda cold dark matter (LCDM) theory. Of course, we have not been able to observe dark matter, which is a problem for a theory. That is what has given rise to MOND, amongst other things. There are prominent, esteemed physicists who have recognized many issues with LCDM, some of which are addressed by MOND (https://astro.uni-bonn.de/~pavel/kroupa_SciLogs.html)

so i put on my scientist hat and started to write a reply going through the mechanics of beating water's heat capacity, first pointing out that what you want for these types of systems is likely high volumetric heat capacity rather than gravimetric. then i went on to discuss the density of room temp ionic liquids (RTILs), only to find myself digging into their heat capacity numbers and man, you're right! I forgot how well water stores heat compared to other liquids. RTILs vol. heat capacity has trouble breaking 2 J/cm3-K![1]

yes, but undoubtedly the UK's security services know that the best way to pass something unpopular is to recast it as helping

children

women

the vulnerable

much like the content of the 2010 CIA memo that wikileaks released[1] stating that the best way to increase public support for US military actions in Afghanistan is to emphasize the oppression of women

this article reads like it was written by a LLM

"Anyway, we all already know this because we all experience human life in 2023."

there it is! enough arm-chair theorizing by computer "scientists", an actual material scientists! or condensed matter physicist, or crystallographic expert, or inorganic chemist...

It sounds like your suggestion came about by mis-reading the parent comment, but I will offer my 2 cents: yandex.com's english results for hard to find, technical terms are infinitely better than google's.

as someone who remembers How Google Used to Work, Yandex feels like Old Google. It indexes the hell out of long tails, will find exact, specific terms and phrases, and 100% respects generic search operators such as exclude "-".

do I look for news articles on it? hell no. do I find the unfindable (on google, and increasingly, on duckduckgo)? yes, I do.

HN always surprises, wouldn’t have expected boutique theoretical crystallography before 9 am.

Hah, I'm not anti-stew. It's a conception you run into a lot, that healthy vegetarian food is a brown stew of chickpeas. I threw that in there for the skeptical.

no, they are not "terrible", they're not complex proteins - excepting eggs. you have to mix two sources of simple protein to equal complex. good, bad; whatever your characterization of them may be, that's the foundation.

you again seem to be conflating your ability to measure something with the method itself being good. I think it's impossible for us to say your vegetarian diet is healthy when you say it makes you weaker, yet you point to being predictably weaker as a sign of knowing what you're doing? I'm not following.

Seeing this response so high up makes me a bit sad.

There's a lot of ways to eat vegetarian, and all the ones that I can think of that require supplementing protein and vitamins are unhealthy.

It should be obvious that eating a way that "had immediate negative impacts on recovery" indicates that what you're eating is not healthy.

You see this with a lot of omnivores, they try cutting meat out of their diet and complain. But, the thing is, an omnivore diet without meat is a deficient diet. It sounds a bit intimidating but you really have to rebuild the way you eat if you've been eating meat.

Cultures that have a vegetarian tradition (even if not described as such) provide a rich tapestry of foods to make a healthy diet rich in protein and vitamins. Ethiopian, Persian, Indian, Sri Lankian; these are just some of the cultures a successful and healthy vegetarian will take inspiration from. Eat like a world traveler and you can forgo meat without being unhealthy.

Quick list of good protein-rich ingredients across cultures:

Mushroom

Quinoa

Eggs

Halloumi

Chickpeas

Green/brown/red lentils

Peas

Paneer

Yoghurt

Walnuts/almonds/sunflower seeds/pistachios

And forget stews. Roast, broil, saute, crisp, brown! There are flavors unlocked by the family of Maillard reactions - the technical name for the chemical reactions that give rise to browning - that we associate with meat but are common to the process of roasting. Savory vegetarian food is a thing.

While I see you are replying to my comment, you're not reference anything I wrote...

As others have pointed out, the choice of the age range has a significant impact on the conclusions one is able to draw. In particular, this paper defines "Children and Adolescents" as 1 to 19 years old, which captures a lot of firearms related deaths due to gang violence.

Unfortunately, politics and culture war are infused in everything. But, if you want to be informed so that you can make better, persuasive arguments, I suggest looking at the CDC Child Health data here: https://www.cdc.gov/nchs/fastats/child-health.htm

TLDR: non-accidental deaths are weighted heavily towards 15-19 year olds, and due to that cohort's fraction of the 1-19 year population, when 15-19 year olds are lumped together with 1-14 yos, it allows someone to present data that homicides are the leading cause of death for 1 to 19 year olds. The further refinement from homicides -> firearms is presumably disambiguated in the referenced paper.

While the authors are obviously free to frame the data and discussion however they please, this strikes me as a paper designed to serve a policy position or perhaps guide political action more so than an even handed look at childhood deaths. Add to it the emotional impact that we're talking about children here, and I find it verging into the emotionally manipulative.

edit: wow, HN really dislikes my efforts at a well-formatted post. hopefully corrected now.

Interesting. I cynically view this (brushed motors with reduced lifetime as compared to brushless, sold as a benefit b/c free of rare earth) as just another self-serving decision automakers can make in the push to reduce the usable lifetime of EVs.

The longevity of ICE/hybrid vehicles has long been a bugbear for auto manufacturers. One of the convenient things for them in the push for EVs is that EVs will inherently have less utility at 10 - 15 years than ICE vehicles.

With manufacturers' standard EV warranty including 70% bat capacity at 10 years or XYZ miles, it's almost like an ICE manufacturer saying your gas tank will get 30% smaller after a decade. Except that an aging battery also has reduced current draw and thermal allowances, so there is also less instantaneous power available as the battery pack ages.

This is an engineering reality of battery EVs, to keep them safe as their packs age. The power limit could be viewed as consistent with older ICE's not performing at nameplate HP, which none of them will without significant maintenance.

But this is why I'm cynical about automakers and EVs: EVs lower their cost burden in the medium to long term with simplified production, and "enhanced" planned obsolence via wear components that are much more expensive and can significantly limit the utility of the vehicle in the 10 - 20 year time horizon, as compared to ICEs and maybe hybrids.

Has the list of client companies been made public anywhere?

I use Containers with Transitions (https://addons.mozilla.org/en-US/firefox/addon/containers-wi...)

It's a bit tedious to set it up at first but it's the only way I know of to get the following functionality:

With GMail open in a "google" container, non-google domain links open in non-google containers (configurable which container if any). Google domain links (drive, calendar, maps, etc) open in the google container.

Once setup, this means in your "standard" or non-specified container you can log out of all google services and stop their most explicit tracking of you through simple account cookies being read across the web while you search, etc. No longer when you visit sites that allow sign-in with google will your account name be auto-suggested, because the sites don't have that level of tracking info when you're browsing and searching outside of the google container. Viewing random trash yt videos will no longer sway the recs you get in yt.

The downside is that my google searches, done outside the google gulag, run into captcha prompts b/c I guess google search doesn't expect that much consistent traffic from someone who isn't signed into one of their services.

edit: this also means that you can, for example, containerize gmaps and set it up so that non-google domain links followed out of maps open in a non-google container. clicking a link to a business's website from their gmaps page no longers propagates your google account cookie to their site, etc. it opens in a different container, automatically.

I can't speak to Norway's penultimate ability to find and raise shipwrecks, but in general the Nordic countries plus the Netherlands have a strong history of shipbuilding. This includes technical knowledge and know-how with all things related to ships.

In a Eurocentric point of view, the Dutch are probably the most famous for their capabilities[0].

In NA, Protolabs is quite good but not inexpensive.

Why, when I lookup my address, do I not see my regional cable internet provider? Yet, when I search that provider, their service availability is shown as 100% in the hexagon covering our home.

While I think I understand that the intention of this map is to document Telecom-asserted coverage such that users can contest inaccuracies, a beneficial flip-side (for me) is to ensure that my regional ISP is accurately represented.

I'll take a non-Comcast/Verizon/National ISP over a National any day of the week. I want their coverage to be accurately documented.

Any chance the Ethernet-equipped version will support a bridge mode? I’d love to distribute my LAN served by the incoming wifi connection to an ethernet switch local to the ATV.

Centrifuges are used for separation. An ultra is usually used for separating nominally-stable colloids (such as fine nanoparticle colloids), and miscible liquids where such high centrifugal force causes them to density separate.
