Wirecutter performed a similar experiment a few years back. Their results were somewhat different, showing that the DIY version helped significantly, but not nearly as well as the best of the commerical ones they tested:

I wonder what accounts for the difference in results.

- I was in the middle w/r/t alerts and have a 3yo iPhone X

I have a couple of blu air purifiers. They really cut down on the amount of dust in the room. We used to have to dust weekly, in the rooms where we have the purifiers we dust maybe every other month now and you can't tell a difference.

> the mass media portraying her as a rebel for coloring her hair, that's like... Tabloid stuff.

I think you're underestimating the stigma against different hair colors in Japan. Japanese culture puts a heavy emphasis on not sticking out, to the point that even having a natural hair color that is different from the norm can be viewed as being rebellious.

I really like the idea of automating these things, I am pretty sure I miss out on a ton of free deals and good opportunities to save money. However, the amount of trust I'd have to have in any system where they can scan all of my email with impunity.... Hooo boy. Ain't going to happen anytime soon.
I heard this on the radio the other day, which turns this observation on its head:

> I want science to give us a sense of wonder. There is this great line from the film Contact that I think Jodie Foster delivers, along the lines of "the universe is so large and we are so small and therefore insignificant, but also incredibly precious." Most of the matter and energy content in the universe is dark matter and dark energy. And therefore what we can see — stars, us — we are what's abnormal about the universe, and we are therefore incredibly precious. So I think that there's something really majestic about being able to situate ourselves in context of this incredible thing that is the universe.

(apologies, this is probably only a free listen in Canada) https://www.cbc.ca/radio/quirks/mar-27-covid-pandemic-origin...

Without observers, the universe would be completely without meaning. We are the most significant thing out there. We make it interesting, by being interested.
Hey! I'm Ansgar. I build Arc. The impact is negligible. Notably, Arc never uses cellular connections -- both to preserve battery life and never use cellular data. Wi-Fi (or ethernet) only. And all activity ceases as soon as the tab with Arc is closed.

What on earth is an on OCI runtime? How are its permissions configured? Here's some issues with some random flags to configure: https://github.com/containers/podman/issues/6368 . How are these linked to podman? The devs know, where is this documented for Joe random user?

Or another one I ran into:

https://github.com/containers/podman/issues/7830

Again, here's some settings in files in /etc/containers to configure that might fix it? Where is this in the podman docs, or release notes? Just found my pods didn't start after an update one day and had to dig into github issues.
I think good-bad is not a fair comparision to classify hedonism into one of them.
There are generic pleasures like money/sex , and subjective pleasures.Both can easily spiral into greed, malice and prejudice, none of which we really want too much of.
I agree with your comment's parent. Russia does that sort of shit currently to their tech (VK and Yandex). While they are strong in Russia, they have no more chances to compete outside of it.
"the numbers are not reliable, says the researcher themselves".

> And no, you don't do this while the CSG is already in range, that's ridiculous. You do this when it's ~2000km away.

The AEGIS Cruiser's tomahawk missiles have 2500km range.

You're not even outranging the escort ships, let alone the carrier at 2000km. That's why two AEGIS Cruisers escort a carrier.

BTW: This magic drone that can escape detection yet provide enough intelligence to pinpoint ships so that missiles can strike their targets on the high-seas sounds a lot like an F35.

Inspired by the recent post about simulating Pong circuitry, I thought I'd share this video that was recently shared amongst SunVox groups.

It's a working Game of Life implementation, with output to an oscilloscope view. The video goes into detail about each subsystem and how it's organized.

What does this have to do with Pong? His previous video is a working, interactive game of Pong, also implemented in SunVox using oscilloscope output.

Turing-complete modular synthesis!

This (that time is a dimension) is as I understand what most physicists believe today and constitutes the so-called eternalism (or "block universe") philosophy of time. According to this view, past/present/future are our (human) terms to explain what is already laid out and we're simply moving along the time access just like we move along in space (though of course only in direction).

I've become a big believer in this view. A valuable upshot of embracing eternalism is that it makes it much easier not to regret the past or worry about the future, though some believe it encourages risky behavior.
"But if we started to take diagnostics that had higher dimensions and resolution, and just trained blackbox AI on that data, it probably stands to reason that..."

...that we would have no way to evaluate the systems' accuracy because no other non-statistical system can understand the input data?

The Oracle at Delphi is always correct. Even when the Oracle is wrong, the Oracle is correct.

"...just fencing off the highways and inventing an autonomous system of vehicles that doesn't have this much tougher constraint...

Kind of expensive to build a second interstate highway system, though.

Yep! Browser-to-browser peer-to-peer connections are established over WebRTC, data (fragmented, encrypted file pieces) flow over the WebRTC data channel, and the data is encrypted in transit with DTLS.
Corporations didn’t lead the charge but they have a higher chance of better compliance because of their size and age. There are of course superb independent restaurants but there are also terrible ones, a corporate parent provides a decent signal that a minimum of safety policies will be followed. A finicky machine that breaks all the time because exact procedure isn’t followed sucks for uptime but is great for safety. Preferably the ergonomics of the thing would be redesigned for robustness but it seems incentives aren’t aligned properly.
Some people like that workshop-esque aesthetic. I find it nicer than the clinical Ikea aesthetic.

Some are but there are still a lot of hold outs. I recently struck up a conversation with a female working for one of the larger ones. Probably had 10 years experience but was being paid close to what she would've made at a conbini.

You don't need orientation handling if you've cut all the other signals, so...

Power negotiation is also not a big problem. Just use a correct resistor on the CC pin and you can make the phone use up to 5V/3A, which is plenty for any smartphone. You'd have to make sure to use a 5V/15W capable power source, though.

Standard Apple cables already have a chip inside, and USB 3.1 cables are also supposed to have chips inside.

I would also assume they are not paying enough attention to even notice, there is no regulation against them so there is no reason to even train to notice differences in USB cables.

> They probably see thousands of cables and it'd be pretty easy to spot the difference.

If anything seeing thousands of cables will make them less likely to notice anything, change blindness is a real problem in jobs like that.
Look at Rick Beato's ear training course (https://rickbeato.com). It's $119 but you get 100 modules. Private lessons are commonly $20-$25 per half hour so this is a pretty good deal.

I've been running one of these for a few months. The filter has slowly turned darker brown - which suggests it's working (not anywhere near forest fires here!).

It has a trickle mode which is completely silent and uses about 1W of power. Something you won't get on a DIY fan.
So you mount another, smaller fan inside of the box fan to cool the motor ... I wonder how far this can regress.
I'm not sure what it means to have a recall of 50%... For nearest neighbour search, you would only find 5 of the top 10 nearest entries? What would be the algorithm of choice if I need to find 9 out of the top 10? Would it be LSH? (In our case, we have 1024 features, and plan to move to 2048; this is for image similarity search; a few million images)
Lots of classic HN dismissals here, though I am glad we as a community have finally gotten past the anger around requiring JS to use the site.

In my mouth, Twitter is probably the best, most responsive web app I've ever used. It is not trivial to make a responsive infinite scroll that remembers your place on back, live updates gracefully, has useful shareable URLs, keeps memory usage low, loads quickly, etc. To me it's the real proof point for RN web and web workers.
> How were these nonprofits ever supposed to come into existence to restream broadcast TV?

They weren't. The law was really just intended to legalise a few existing networks, it wasn't supposed to be used for anything significantly bigger than a university campus.
I don’t think “political” is meant to mean “controversial” here. There were just some extremely successful awareness campaigns for it in the 80s and 90s (to the point where it’s the stereotypical example of an awareness campaign for many of us), so people care a lot about it.
Do we know how the air flow improves in proportion to surface area? I assume it's not quite linear. It would be good to know whether it's worth the effort to do what you're describing.
It is very much accurate. This is a pretty typical PM2.5 level at winter time where I live. Put a few thousand houses heated with coal close together, add −30-40 °C winters, a particularly bad location where wind almost never blows (maybe ~30 days per year total), and voila.
Sufficiently increasing scale leads to qualitative jump-steps. Complex systems gonna complexify!

Ford was paying more money to employees who were more conformist to his standard of ideal living.

To the hyper individualistic culture like USA today this can only seem bad but this is Japan with factory towns [1] and generally more collectivist culture.

Based on the Quanta article, they're only measuring complexity in terms of how complex a neural net needs to be to faithfully learn a neuron's output (presumably by SGD.) That's probably only a weak upper bound on the complexity, though. There may be more parsimonious ways to simulate the neuron which are expensive to represent in a neural net, or which are hard for SGD to learn.
Nicotine affects cognition and behavior (1). In smokers and nonsmokers, it produces small improvements in finger-tapping rate, motor response on tests of focused and sustained attention, and recognition memory (2). In smokers, tobacco deprivation can impair cognitive performance, and subsequent nicotine administration or smoking can reverse these deficits (3–5).

Yes, there are thousands of people who got addicted without any history of co-morbidity of addiction. But as a portion of people who were prescribed, they are small. Remember we are talking about a drug that had 245 million prescriptions in the US in 2014. Also, 30% of Americans are living with chronic pain. [2] If anything, we may be under-prescribing these drugs.

1. The narrative is that some poor guy took pain meds for a legitimate reason then ended up addicted. While this does occur, it's actually not very common.

> Among people who are prescribed opioids, addiction is relatively uncommon. The percentage of patients who become addicted after taking opioids for chronic pain is measured in the single digits; studies show an incidence from less than 1 percent to 8 percent. Most of the estimates are skewed toward the low end of this range, when those at risk (due to a history of substance abuse or, to a lesser but meaningful extent, a concurrent mental illness) are removed from the sample.

2. Most addicts had a history of drug abuse.

> People who abuse pills are rarely new to drugs. The federal government’s 2014 National Survey on Drug Use and Health, for example, revealed that more than three-fourths of misusers had used non-prescribed benzodiazepines, such as Valium or Xanax, or inhalants. A study of Oxycontin users in treatment found that they “were not naive individuals with accidental addictions who were introduced to painkillers by their physicians as reported by the media … [Instead they had] extensive drug use histories.”

It's hard to bring this up without straying into classism or victim blaming. The reality is that most people without comorbidities and abuse history are quite safe, and these are drugs we need.

My claims are actually backed by published research (cited within the Atlantic article if you want to check)... Maybe you could like read before you get shot down.
They see thousands of cables and probably don't give any a second glance for the bare few seconds they gaze at each bag, an extra IC or two in the connector or not.

The sheer volume of bags that get run through those x-ray machines in a shift, and the time given to look at each one precludes too much fine grained inspection, especially for something as minor as cables.

Airport security is pretty dismal at detecting actual weapons or contraband, why should they be any better at noticing a slightly different cable?

> I don't really blame people, since git itself does nothing to teach you how it works. Git it is the definition of something you have to deal with in order to do something more important to you. Some people want to dig deep and understand how the system works: it's nice to sit near that person and ask them for help sometimes.

The official git handbook, freely available on the official git-scm site is not terribly long, and explains the internals on a conceptual level quite well.

I think the problem is most people learning git land on some wordpress site of someone trying to flog a condensed and uninsightful shortcut to getting started with git for ad clicks, which only involves a series of commands without explaining the effects of those commands - This, combined with peoples expectation that an SCM should take no thought whatsoever causes most people that use git on a day to day basis to not really understand it at all.

Git needs to be introduced as powerful data structure, kind of like how SQL is not a DB, imagine someone explaining SQL without ever refering to the DB tables, rows and fields... only talking about git commits is like only talking about the result of a single query. You must understand the data structure to easily use the interface, otherwise the interface will be very confusing or you will be limited to "recipes"... after that you are just learning new variations on how to manipulate and navigate that structure (yes the graph), and from this perspective peoples complaints about the historical inconsistencies we have to put up with in git porcelain are moot.
Really? That's fascinating to me because the music in my head is the actual music as if I were playing it off a CD. In fact I've learned many songs "by ear" just using the music in my head.
Yup. It's actually an incredibly clever piece of tech that lets the iPad/iPhone get around the fact that lightning doesn't have enough bandwidth to transmit HDMI.

For regular home/app views, it does hardware compression of the iPad's screen, outputs that over lightning, then the adapter decompresses it to raw HDMI.

While for Netflix/etc. streams, it outputs the stream directly to the adapter to decompress, without quality loss. (And at full size as well, rather than double-letterboxed.)

I still haven't figured out the magic of how apps like Netflix are able to do overlays of subtitles on top of the compressed video stream. Best I can tell, there must be a separate API for that, that gets sent in parallel.

There is still apparent dust after years (have cats)
but OMG the filters get gross.
Probably cheaper MERV 8 filter would make more sense, since for this application you're mostly concerned about those larger dust particles. Also it seems like this would be a job for the fan manufacturers rather than the PC case manufacturers. The fan just needs a little slot where you can slide in a thin replaceable filter.
Are you going to attach these transmitters to every deer and every pedestrian? If not, we're back to 'elevated or buried road so we don't have to worry about animals and people- why not just build a train?' or 'AI which can solve the whole problem on its own' or 'If I recognize something unusual hand off back to a human, hope that they were paying attention and know what to do.'

And that still leaves aside tricky things like construction sites, double parked cars, etc.

Commercial airline autopilot has a lot more straightforward job: at normal operating altitudes there are no animals to worry about, no construction or other unexpected obstacles, and few other aircraft all of which can be essentially guaranteed to be squawking transponder codes of their own, and they still are mandated to have two pilots in them at all times. This is not because airlines like it- look how fast the flight engineer disappeared once flight management and navigation software became sufficient. It is instead because airlines have learned over the decades, from a lot of blood, that sometimes you need to have a pilot ready to intervene RIGHT THIS INSTANT, not 3 minutes from now when you've regained situational awareness after zoning out for a bit- and the AF447 disaster shows that they are right about that. And the only way to make sure you have such focus and alertness over many hours is to have two pilots, so they can trade off the responsibility of maintaining SA.

And that's a much easier problem which has been actively attacked for decades.
4 inches is deep for a standard dimensioned MERV-rated filter. It’s normal for a high quality but sadly usually proprietary fancy HVAC filter (Aprilaire, Lennox, etc).
