These articles made sense 5 years ago when there were only a few high priced air filters widely available online, but now the chinese copies have proliferated amazon and other sites and the market is pretty saturated imo. My filter was $30, about the size and look of a larger bluetooth speaker, it is dead silent on the lowest setting, replacement filters another $15 or so, and its good to filter my bedroom pretty heavily in terms of square footage. Can't beat that. At that price we have one of these in a couple different rooms.

For those who hurt their heads thinking about why this works:

The bright dots show that there is lots of energy in certain repeating edges (the halftone dots). Since we don't want that energy, we force it to zero by painting it black. This this is essentially saying: "delete all the halftone dot edges, keep all other edges".
That's because the maker of a drug is expected to know more about it than doctors. And when that maker conceals information about it with the deliberate aim of causing overprescription, we are justified in blaming them far more than the doctors they fooled.

Purdue Pharma knew about “significant” abuse of OxyContin in the first years after the drug’s introduction in 1996 and concealed that information. - https://www.nytimes.com/2018/05/29/health/purdue-opioids-oxy...
I'm a solo developer, and I have a project that totally can do it. I've done the proof-of-concept in an afternoon, but am mostly focused on web stuff atm.

Granted, it leverages NativeScript, but it's really not that hard once you have that.
I was curious about this problem, and found that the pull request for "Implement WKD" (in the web app) was merged[0] in December 2019, and there is a bug report[1] from October 2020 complaining that the Android app can't look up (some) WKD keys. That bug was last updated in November 2020 and is still open.

Filter's airflow restriction is primarily a function of surface area and filtration medium layers. More surface area results in a better airflow and more filtration medium layers results in a worse airflow.

To maximize surface area of a filter, you can get a thicker accordion filter. This will generally provide good airflow and filtration characreristics.

Sorry about video links below, I liked them at chart times, so you don't have to watch the video to check out the summary.

Here is an example of airflow restriction vs filter. Note that 4 inch Honeywell filter only provides small static pressure rise over no filter option: https://youtu.be/RkjRKIRva58?t=456

At the same time, same filter is 5th overall in large particle removal: https://youtu.be/RkjRKIRva58?t=661

Thicker filters cost more, but also last longer. General rule seems to be that when you double the filter thickness, time between replacements doubles as well.
If the last twenty years have taught us anything, it is that unimaginable amounts of unconscionable evil may be done "legally". That is certainly not the criterion to which thinking people should limit our judgment.

We subjects don't decide our laws and regulations. [0] Instead, those are written by lawyers and lobbyists in the employ of reptiles like the Sacklers. They make the rules by which they play, so when we're told to "hate the game, not the players", well, they get that hate too.

What platform is carrying that hypothetical lens? How does it avoid being destroyed before detecting and tracking the target? How does it data link targeting targeting data back to offensive platforms? What is the visible horizon range at its operating altitude? How well does it see at night, or through clouds?
So when we legalize all drugs because 'the drug war isn't working' (something I agree with) who do we sue then?

I just think the public is overly reactive to whatever problem is at hand. When the drugs are causing crime we want them legalised. When they are causing addiction we want to producers prosecuted.

Opiods helped a lot of people. And the media has constructed this narrative around them being highly addictive which isn't really true.
Pfizer to Roll Out Covid Pill
In my experience, no it's not worth it indoors in a relatively clean environment. I built 3 of these for myself with dust, carbon, & hepa filters, and I used them for over a year.

They are louder, use more energy, are less efficient, uglier & cost more money than several store bought alternatives which often include several carbon & hepa filter replacements which is the main expense in building these fans.

They work well in the garage though, and if you don't plan on changing the filters frequently they are the cheapest build option.

One thing I love is that he apparently got a Professor position not requiring him to do anything but the podcast and teaching. The Podcast is truly great and possibly the most important piece of work in the field of history of philosophy of the last few decades. I know multiple people who fell deeply in love with the field thanks to his work.
If you notice your fan motor or cord getting hot you can reduce the pressure differential (and therefore torque/load on the motor) by allowing some airflow to get around the filter- i.e. push the filter a bit to the side or add a tiny gap between the filter and the fan by sticking in a little block of wood.

This will come at a cost of filtration effectiveness (less airflow going through the filter) but will save your fan in the long run. Make sure not to let your gap or hole get too big or your filter will stop flowing enough air to work.

Ask HN: Can I hire an agent or how to get short-term contracts?
I'm looking into transitioning from full-time job into short term contracts. Ideally I would like to sign in a project for 1-6 months, do the job and have month or two off. Is there a good place to find such contracts outside of my LinkedIn network? Is something like agent for developer a thing? Kind of like authors, singer and actors have. I would love to hire someone like that, give him a cut of of contract and carry on. If it's not a thing someone should make startup out of it.
It depends on the accuracy of the humans as well. Less accurate doesn’t mean not accurate.
Well, the current understanding is

1. The universe was created by the big bang, which created all the energy and matter in an instant. In the first few moments, this soup of energy and matter was near-uniform, but tiny imbalances caused matter to start clumping up into larger clumps.

2. Fast-forward 14 billion years, and those tiny imbalances and the resulting forces appear to have distributed the matter (including dark matter) into a fairly even, consistent structure across the entire universe, with galaxies mostly collecting together in clumps separated by huge filaments (see e.g. [1]). Our own galaxy seems to be in a bit of a void between some of these clumps.

So that's our understanding of how the universe came to be, and how it came to be the way it is now. It seems that things are, as I said, "pretty much the same" no matter how far out you go, and this has an explanatory reason: the near-uniformity of the matter and energy created by the big bang.

You're saying that it could be that, somewhere, outside the reaches of our telescopes, things are totally different. But we have no theories of how that could possibly have come to be, given our assumption #1 above. It just doesn't seem plausible, given our understanding of the big bang, that somewhere on the "other side" of the universe there's, say, nothing at all. Or a pure carbon crystal the size of our own observable universe. Or a Library of Babel.

You're free to say "well, scientists don't know that there isn't," yes, of course, but without some kind of explanatory hypothesis, it makes far more sense to go with the data and theories we have.

My reticence comes from not being fully confident in our ability to regulate technologies with an essentially luddite governmental body when it comes to tech they do not wish to fully understand. Perhaps if we change how they learn about new developments we can expect them to make informed decisions regarding something like organic AI.
The Tomu is super cool! It also has a bunch of spinoffs, the most interesting of which IMO is the Fomu (https://tomu.im/fomu.html). It's an ice40up5k FPGA in your USB port, not sure if you can get them anywhere due to the parts shortage but I know I've enjoyed hacking on mine.

The thing that drives me crazy is that it breaks a basic feature of the browser, which is that if you load a bunch of tweets in your feed and then ctl-f to search for something, it doesn't work (on Chrome, at least); it doesn't find stuff that's on the page.

This is particularly frustrating, because my normal use case for this is that a bunch of new stuff loaded, which throws everything that's on the page already out of order, so then I can't see something that I know was there, that I was just looking at, and now searching for it doesn't work, either.

Cost is relative. When you're attacking a carrier you can afford to sacrifice a lot. A surveillance drone can very well be used in a suicide role, and they have more than enough range for this task.

Antiship ballistic missiles have strong maneuvering capabilities. You have to look at absolute displacement, not the relative change in velocity. And the sensors required to find a 7000m^2 target are much smaller and limited than you'd think.
Yeah, it's fine for "reactive" processing but not for anything where you'd actually spin up a separate thread (or use a threadpool thread) in a lower-level language - i.e. to perform cpu-intensive calculations/computations in parallel. In practice, JS being single-threaded isn't an obstacle for the uses the developers using JS are after. It doesn't sound like Ruby 3 affords the same with its GIL (but all I'm going off of is TFA).
Designing Distributed Systems This is more for devop folks, rather than creating your own distributed system.
This really has nothing to do with HDMI. It has more to do with how Dolby makes money. They pay film and TV studios to mix in ATMOS which can only be decoded using Dolby's licensed chip technologies (it's not implemented in software, usually) which they sell to OEMs. HDMI is just a transport layer, it's not the only one for ATMOS just what is most commonly found in consumer devices.

That said, phono audio connections are objectively terrible and their only redeeming quality is simplicity. I'll take HDMI ARC over it every day, because I don't want multiple control points for my audio signal.

There's also a new standard for immersive audio bitstreams that will hopefully result in software decoders but I doubt we'll see that in consumer gear anytime soon.
I was a bit confused by exactly what the percentage in the headline was, so here:

>> In two of the largest retrospective cohort studies of AI to replace radiologists in Europe (n=76 813 women), all AI systems were less accurate than consensus of two radiologists, and 34 of 36 AI systems were less accurate than a single reader

I'm still a little unclear how you measure the accuracy of a consensus of radiologists, without relying on the consensus of other radiologists. Maybe just a bigger consensus, or by using known end results but looking at imagery that could have been an early warning?

I see your point, but there have certainly been accusations that the Sacklers directed operations and while knowing risks associated with drug doses. An NYT article from 2019 [1] Sacklers Directed Efforts to Mislead Public About OxyContin, Court Filing Claims lays out the accusations. (I'll try to find the subsequent ruling and add to this.)

From that article, albeit citing the prosecutor's case, "... internal Purdue communications are cited by the attorney general of Massachusetts in a new court filing against the company, released on Tuesday. They represent the first evidence that appears to tie the Sacklers to specific decisions made by the company about the marketing of OxyContin. The aggressive promotion of the drug helped ignite the opioid epidemic.

The filing contends that Mr. Sackler, a son of a Purdue Pharma founder, urged that sales representatives advise doctors to prescribe the highest dosage of the powerful opioid painkiller because it was the most profitable."

Oh My God!
Wonder if any PC gaming case manufacturers will ever think to add some HEPA filters to the unit - be good for the PC to have cleaner air going in and that airflow out would be put to good use to cool the PC.

I recall seeing a video (BigClive on YT) in which he gets a fan and used a peace of kitchen roll as a filter and found it fairly effective and just dug that out - https://youtu.be/kK7sJq2E0bE

The product pages mention custom payloads, in some of the images it looks like some variant of the DuckyScript used in some of the other hak5 products. It likely depends on if what you want to do is supported or if it would need changes to the firmware to accomplish.

Ditto. Mine is really quiet too on low settings, which is great if you want to leave it on while you sleep.

They also have a carbon layer that's supposed to help with odours and that pollution that can't meaningfully be caught by a simple HEPA filter, although I don't know how effective it is.
The lens is given as a general example you can easily apply the Rayleigh criterion to to verify. You can use many other types of sensors.

You could carry such a sensor on a satellite, a drone, or even the missile itself.

You need to get within 300km of the carrier once. It doesn't matter if it's the 15th try or if you don't survive either. You really overestimate air defences if you think an airwing can do that. And of course you can make even better sensors, we have the technology and it's been practically done.
Your implication that they were "agents provocateurs to smear the rest of the peaceful protestors" is lacking evidence, where there is plenty of evidence, both in testimony and captured communications from various groups of protestors intent on committing violence and mayhem, to the contrary.

At best, those "peaceful" protestors (who somehow in their naive purity managed not to be able to read the vibe of a crowd that erected a noose and gallows outside the White House, or notice the rioting, broken doors and tear gas) are still at least guilty of trespassing, and some of vandalism.

> That same year, the CIA and the German Federal Intelligence Service secretly acquired CAG for US $5.75 million. (Also in 1970, Hagelin's son Bo, who was the company's sales manager for the Americas and who had opposed the transaction, died in a car crash near Washington, D.C.)

I understand that coincidences happen, but they seem to happen distressingly often to people who get between the CIA and its goals. Government that finds the source of its power in the people is difficult to maintain when popular involvement in important matters carries such risks.
Largely false. Managers have pretty wide latitude to approve compensation matches for employees they want to keep without up-leveling them. So if you're a star L5 at Google and Facebook is giving you a $MM E7 package, you could end up with a $MM stock grant (which would normally be reserved for L7+) at Google. Compensation raises are tied to level, but that just means that you'll sit and vest your existing stock grant without further raises or refreshers until your formal level matches your comp package. This happened semi-frequently in the ~2010-2011 era when Facebook was recruiting heavily out of Google with pre-IPO stock.

The promo process is based on your value to your employer, and at least at Google is done by committee, which is drawn from a selection of high-level employees outside of your manager's department (so they have no incentive to keep you) and has a packet of information that does not include anything about your market value outside the company.
I worked for a UAV development firm as a student. Since that time, I have always thought that the "UFO" cultural phenomena was largely a response to sightings of very early attempts at unmanned flight. This document makes me all the more certain.

The lay public would have not had any inkling of such technology at that time, exacerbating known problems laypeople have with assessing the size and speed of aircraft. They would have been primed to think in terms of extraterrestrial life by a long sci-fi tradition.
When you say “act”, what do you mean? There are a lot of actions that people take every day, from complaining on Facebook, to boycotting companies they don’t like, to going into the streets to protest, to sometimes making bombs and blowing up buildings.

Ummmm... yeah they can. If we're talking about 10-minutes for a hypersonic missile to arrive, that thing's bearings / velocity can be completely different by the time the missile arrives on the horizon.

I'm still not really convinced that you'd detect a carrier first in most open seas. Carriers would have airplanes of their own, scanning for enemies, and a number of anti-air destroyers ready to shoot down any spy plane. You call it a numbers game, but IMO, its a sensor game.

Any airplane who approaches the carrier has to themselves, survive the Carrier's defense systems (including the defensive spyplanes keeping watch over the carrier group)

-------

> In the case of a carrier, you need very low accuracy - in the 10 meter range instead of the centimeter range - very low sensitivity, because the target is positively huge and sticks out like a sore thumb from its surroundings, so you can get range.

I'm not sure if the carrier sticks out that much in its CSG. No carrier works alone: there are a lot of other ships floating around it providing support.

Personally I don't believe the (non-)progress Amazon's plans have any relevance with whether their complaints about SpaceX are abusive. "Amazon files more complaints than SpaceX" is similarly irrelevant.

I consider the complaints abusive only if they are entirely without merit and are just taking FCC's time for nothing (which they might still be - but just SpaceX saying so is not enough for me).
