Interesting... What benefits does this have over vitamin D supplements?
I've seen this "optimising for some perceived negative effects" thing with toothbrushes/toothpaste, where "whitening" and stiff bristles actually just means removing more (irreplaceable) enamel from your teeth.
Many people with inflammatory disease like IBD can't absorb oral vitamin D properly
Even in healthy people, oral vitamin D is not always sufficient (there was a study done in Japan where sunlight is low but Vitamin D from fish is high - can't find it right now) and sunlight exposure might have other benefits than vitamin D anyway
Vitamin D supplements are controversial on their own.
There is ample results on better health correlated with higher levels of Vitamin D, but the reverse is far more teneous: shoving in Vitamin D isn't guaranteed to be properly absorbed, and even when it is we don't see conparable results to people producing the Vitamin D themselves.
Unless you are deficient it's not the vitamin D. It's a whole host of other processes that benefit your body from sun exposure and the activities that go along with it. The Vitamin D is just a marker that we can detect that can also be related to that same exposure. So there's a huge number of things for which people with high levels of Vitamin D do not suffer but supplementing has no effect because the vitamin D is only correlated not causative.
But wouldn’t this imply that optimizing the tanning bed properties for vitamin D production is worse than looking for as-close-to-sun-like sources of light?
The paper covers a lot, some are administrating vitamin D as a prevention measure, most are on vitamin D deficient patients. e.g
> Even in the small subgroup of subjects with a poorer vitamin D status (serum 25OHD < 20 ng/mL), no effect on fracture risk was observed (hazard ratio [HR] = 1.07; 95% confidence interval [CI] 0.91–1.25).
> A large RCT in Mongolian children with severe vitamin D deficiency did not find a beneficial effect of vitamin D supplementation on the subsequent risk of subclinical or clinical tuberculosis.
I have issues with low vitamin D and even really high supplement doses like 10,000iu/d do nothing at all- my level keeps dropping no matter how much I supplement. Sunlight brings it up quickly but not in the winter from Nov-Jan.
Vitamin D supplements don’t work consistently across different populations. Very few (~10%) of people can absorb dietary vitamin D. If you aren’t some form of Northern European, you probably need to take at least 10 times the daily recommended dose of vitamin D to influence your levels significantly.
Don't most people who take supplements just take 10X the RDA? It is still a tiny amount of supplement that is safer and costs a fraction of the indoor tanning or traveling often to somewhere with adequate Sun.
I’ve never talked to someone supplementing vitamin D who was aware at all.
I think that the correct approach would be start at 10x vitamin D with baseline bloodwork and adjust dosage from there.
But yeah I’m in the camp of “sun is good for you, in most cases.” I would be very unsurprised to find that there are precursor hormones released beyond vitamin D that impact efficacy. We don’t really understand the endocrine system very well.
I think that because we can see and understand the dermatological effects we overly weight them. Anecdotally older people I know who have not avoided the sun seem much better off mentally and physically, but I think because there isn’t a measurable reason we’re aware of, we completely discount any benefit.
Stiff bristles also damage your gum more easily and can lead to gum recessions. I needed gum transplants because of this and a wrong brushing technique. For me even medium stiffness is too hard.
That's only if you're using the Arduino IDE though, and it's so commonplace that instructions are widespread. Many are using MicroPython/CircuitPython which are independent from Arduino.
I wonder if it's using a compass and odometry (distance) with dead reckoning. A strange choice when GPS is available, but it would account for the map moving in the car's direction and it not changing locations when it moved without rolling (ferry).
Almost certainly. GPS is not only easily jammed, but easily spoofed. If the car believed GPS instead of its own eyes, so to speak, then there’s significant potential that you’d see glitches more often. It could also be something of a safety risk when using its self-driving capabilities.
Makes me wonder why there isn't a UI feature within easy reach to let the user drag a pin on a map and tap "I know I'm here right now"... and if that agrees with where GPS also indicates, let's it reset its notion of "I must be getting spoofed right now" thoughts in addition to calibrating other notions of current location.
In addition to sibling's comments about jamming and self driving safety, there are many driving situations where there is no or poor GPS reception: tunnels, double deck bridges, double deck freeways, underpasses, urban canyons, actual canyons, etc. Also regional problems. The GPS constellation is in a 55° inclination, so if you are north of ~55N, or south of ~55S, you need a clear view of the southern/northern sky, respectfully, for reception, since there will be no overhead satellites.
Are we using the same Google Photos? I've found Immich face recognition and context/object search to be miles better than Google Photos. In particular, Google Photos is exceptionally bad at distinguishing non-European looking faces (though it's not great in general), and it completely gave up on updating / scanning new photos in 2024 after I imported party photos with a lot of different people.
Almost all my Google Photos "people" are mix-and-matched similar looking faces, so it's borderline useless. Immich isn't perfect, but it gives me the control to rerun face recognition and reassign faces when I want, even on my ancient GTX 1060.
My google photos doesn't even seem to support facial recognition, maybe I turned it off somehow at some point, but it doesn't seem like google photos supports manually selecting a face (a face that isn't detected), which is something I use a ton with Immich, it is very convenient, even if a bit tedious if going through a backlog.
Annoyingly you can't create a person that way yet with immich, but that's where digikam helps.
Immich manages to detect my kids faces much better than expected. I only have two years, but it is spot on with kid #1 from newborn to 2yo, and it manages to not mix up the new baby photos of #2 with the baby photos of #1.
In my 44k photos there are zero statues face detected, the only flukes are a few photos from a restaurant with a celebrity picture wall.
This is definitely just me, but the diagram with "motivation to buy" was amusing to me. I (try to) refuse to be manipulated by these tactics - if I think the software is worth buying, I will purchase and use it, otherwise I will look elsewhere! Nothing sets my "motivation to buy" to zero quicker than aggressive, "uncrackable" DRM. In fact, it usually skyrockets my "motivation to reverse", whether or not I actually need the thing (though usually this is overruled by having better things to do with my time).
Professional software is aimed at people who use it day in day out so they’re optimising for a different problem than software that’s aimed at the casual user.
Intuitiveness is often seen as a outright positive by most people but actually it’s more of a trade off. Often the greatest efficiency is achieved by interfaces that require a bit of learning by the user. The ultimate example of that is command line interfaces which are very powerful and efficient but require you to know what you’re doing and give you relatively little help.
You’re on the other side of a steep learning curve for a lot of professional software you use. A steep learning curve is bad UX.
EDAC is the concept, ECC is a family of algorithmic solutions in the service of the concept. Specific implementations of ECC are the engineering solution that implement the specific form of ECC in specific devices at the hardware or software level.
It’s confusing because EDAC and ECC seem to mean the same thing, but ECC is a term primarily used in memory integrity, where EDAC is a system level concept.
That was my initial confusion as well. It means exactly what you guessed, "Error detection and correction". The term is also spelled out in the report. I asked Claude about it (caveat emptor) and it said EDAC is the correct name for the circuitry and implementation itself whereas ECC is the algorithm. Gemini said that EDAC is the general technique and ECC is one implementation variant. So, at this point, I'm not sure. They are used interchangeably (maybe wrongly so), and in this case, we're referring to, essentially, the same thing, with maybe some small differences in the details. In my professional life, almost always I referred to ECC. In the report, they were only using EDAC. I thought I'd maintain consistency with the report so I tried using EDAC as well.
Large portions of this comment provides zero to negative value. You've quoted two LLMs and couched it in "caveat emptor" and "so I'm not sure". The rest of your comment has then mused over this data you do not trust using generalities ("my profession" are you a JS S/W eng? A chip design specialist at ARM? A security researcher?).
All of the value of your comment comes from the first sentence and the last two.
Feel free to consult LLMs, with all their downsides (like you needing to verify what they say, because it could be totally wrong).
What you're doing here is half the job: consulting an LLM and sharing the output without verifying whether it is true. You're then saying 'okay everyone else, finish my job for me, specifically the hard part of it (the verification), while I did the easy part (asking a magic 8 ball)'.
From this perspective, your comment could be viewed as disrespectful of others by asking them to finish your job, and of negative value because it could be totally hallucinated and false, and you didn't care enough about others to find out before posting it.
tl;dr: 'I asked an LLM and it said X' will likely, for the near future, be downvoted just like 'I flipped a coin and it said X'. You should be pretty confident that what you post is not false before posting it, regardless of how you came up with it.
- EDAC is a term that encompasses anything used to detect and correct errors. While this almost always involves redundancy of some sort, _how_ it is done is unspecified.
- The term ECC used stand-alone refers specifically to adding redundancy to data in the form of an error correcting code. But it is not a single algorithm - there are many ECC / FEC codes, from hamming codes used on small chunks of data such as data stored in RAM, to block codes like reed-solomon more commonly used on file storage data.
- The term ECC memory could really just mean "EDAC" memory, but in practice, error correcting codes are _the_ way you'd do this from a cost perspective, so it works out. I don't think most systems would do triple redundancy on just the RAM -- at that point you'd run an independent microcontroller with the RAM to get higher-level TMR.
It actually can, depending on where it is. Paperclip optimizers don't optimize for route length - they optimize for paperclips received. When Vodafone or Deutsche Telekom gets your packet, they try to send it to one of their customers, because their customers pay them to receive traffic, even when it's a longer route.
If you're sending a packet from German Shittytel to German Okaytel, and Okaytel just happens to buy a connection to Singapore from Asiatel to get packets to Asia, and Singapore Internet Corp just happens to buy a connection to German Shittytel to get packets to Europe, they'll be glad to send your packet all the way to Singapore so Asiatel will have to pay them for it. But if you sent your packet to a VPN server in Berlin with a neutral peering with both ISPs, the packet would take a nearly common sense route.
In practice, these situations don't happen, at least not this extreme. Partly because ISPs are trying their best not to be the recipient of this. Okaytel doesn't want their packets to be round-tripped through Singapore - that's a bad user experience and they're ultimately paying for it in money as well. So they might negotiate with Asiatel that Asiatel won't tell Shittytel that it's able to deliver packets to Okaytel - in fact there are often BGP attributes they can set to do this automatically. Business is incredibly cut-throat and incredibly stupid. I guarantee Shittytel has a lot more money than Okaytel because they are better at "extracting value". Not only the ISP business is like this btw.
Clickbait warning... The video that appeared at the top of the page (followed by a bunch of blank space, presumably blocked ads) featuring a superyacht is NOT about the yacht in the title, although it does also have solar panels.
> (...) think pieces on how our lives have become consistently better thanks to these tech companies!
[citation needed]
The data presented only talks about the revenue of the companies, not their effect on the lives of their customers (which is admittedly difficult to measure).
The "I personally don't find short form videos too addicting" sentence is just anecdata and dismisses the negative impacts. In my opinion, being able to instantly access content that "makes [you] smile for free" is not obviously a good thing. Even if attention spans weren't affected, I think the brain is wired for homeostasis (balance), and easy sources of dopamine are dangerous since they affect the main motivation to do real, impactful tasks.
Ultimately, it's unclear whether modern (2010s-now) tech companies have _consistently_ improved lives overall. There have certainly been positive changes but also negative ones. Let me know what you think.
I've seen this "optimising for some perceived negative effects" thing with toothbrushes/toothpaste, where "whitening" and stiff bristles actually just means removing more (irreplaceable) enamel from your teeth.
