I think that a more interesting approach is enhancing the fit of the mask to the face. Apart from improved protection, a better fit means that water vapor from one's body doesn't fog up one's glasses!

One of the references of this paper is exactly about that, with photographs of example setups ("Figure 2"): https://jamanetwork.com/journals/jamainternalmedicine/fullar...

The "mask fitter"/"badger seal" project already received some attention on HN:

https://making.engr.wisc.edu/mask-fitter/

https://docs.google.com/presentation/d/1bTUmxEiZ_EMo9DYjHWl1...

Personally, I used a bit of polycaprolactone to form a hard plastic part that is formed on the nose and on each cheek and which:

1. can push the mask against my face, while its shape conforms to the face, so that it pushes on the surface of the face relatively evenly

2. features protrusions (on the cheek-parts of the plastic) onto which something like a string can be put so that it (the string) goes behind the head and beneath the chin. This string then fixes the plastic piece (and the mask) in place.

Polycaprolactone is a plastic which softens at around 60 degrees Celsius, at which point it is possible to mold/form it by hand (skin contact is safe, and it's safe to let it harden on one's skin). Also, it's biodegradable and relatively cheap: https://en.wikipedia.org/wiki/Polycaprolactone

The main problem with designing something like this is how not to make yourself look absurdly ugly while wearing it on top of the mask ;)
It's not... in fact, I'd say other democracies with less emphasis on wealth at all cost, do it much better.
>based on my understanding of how CS research groups usually function

If you mean supervisors adding their names on to publications without having contributed any work, than this is not only limited to CS research groups. Authorship misrepresentation is widespread in academia and unfortunately mostly being ignored. Those who speak up are being singled out and isolated instead.
It's a tradeoff between capex and opex. Right now, the capex costs are so high that you are more or less forced to run miners 24/7, or you never make back the capex costs.

If bitcoin miners were more opex heavy in terms of Total Lifetime Cost, it could make sense to turn them off at night. As Moore's law continues to slow down, miners slowly are becoming more opex heavy.

I read it as "to the width of the SIMD registers" which I have seen in other quick scanners, but did not read the code here.

Also make it so selling / giving access to location data without explicit opt-in consent, along with notification to users if their data was accessed / rented / sold / used in a thing that others had access to..

The various SIMD ISAs are different enough from eachother that you really want a custom implementation per ISA for perf reasons. Particularly if you're doing something off the beaten path like this rather than cranking through some vector math.
The ratio of DRAM bandwidth to compute is constant no matter how many A100s you use because each A100 comes with its own dedicated DRAM. As a result GPT-3 would likely be faster to train on an A100 cluster with enough DRAM to hold the parameters. But Resnet-50 and WaveNet would likely be much faster to train on Cerebras because they fit in the SRAM. In fact, I believe even the biggest state-of-the-art Imagenet classification models would fit.
Totally agree. It is a threat, not pen testing. Pen testing would stop when it was obvious they would or had succeeded and notify the project so they could remedy the process and prevent it in the future. Reverting to name calling and outright manipulative behavior is immature and counterproductive in any case except where the action is malicious.
The study you cite isn't really in conflict with the parent study. They note that the number of individuals with Alzheimer's Disease in the study was too small to develop a non-linear model relating sleep duration to AD risk:

Pg. 858:

"Similarly, short and long sleep duration and poor
sleep quality have also been linked with an increased risk
of dementia. Although a similar J-shaped association was
observed in our observational analysis, we were limited to
performing only the linear MR analysis, as the non-linear
MR method requires a large number of cases and
individual-level data. In our linear MR analysis, we found
no clear evidence that an increased sleep duration was associated with a higher risk of all-cause dementia in UK
Biobank or with AD in IGAP. This is unsurprising, as the
true association might be non-linear and we were limited
with only 1343 dementia cases in UK Biobank. Also, IGAP
does not capture non-AD dementia types and comprises an
older and more heterogeneous population."

"Results for risks of dementia and AD are still too imprecise to draw any definitive conclusions. Our findings suggest that, in clinical care, attention should be paid to sleep-duration patterns and improved sleep habits could represent a potential therapeutic target for cognition."
No, I think boomers with assets are doing fine. Everyone else is fucked.

I don't want to push the generational narrative too hard(I'm 46), but it does seem like that generation is willing to do everything they can to keep the party going until they die. After they're gone, it will be up to my generation and younger to figure out what to do with the massive debt and distorted economy. From what I can see, they just don't give a shit.
People with amphetamine habits typically look very skinny and unhealthy because amphetamines suppress appetite. Same for cocaine, ritalin and all other dopaminergic stimulants. They can also have facial scabs because of obsessive picking/scratching, and tend to be very twitchy and hyper. He doesn't come off that way at all during interviews.

My personal experience leads me to believe that there is no way Elon Musk could have been dosing stimulants for the last 10-20 years and look as good and as relatively calm as he does. You build a tolerance very quickly, and any edge that you thought the stimulants were giving you will fade away fast. Then, if you increase the dose, your life will spiral off the rails as you become more manic, impulsive and irrational (eg: gambling, sex, spending sprees, irritability, violence, paranoia). Just Google John McAfee if you want to see what this can look like.

IMO Elon Musk just has lucky genetics and doesn't need much sleep, always has high energy. There are people who are fortunate to be born like that.
I don't think "psychological safety" boils down to feeling secure in one's job in the way you suggest, it's more specific than that.

Being able to be your "true" self is the observation, not "be happy". If your true self is a neurotic mess, "psychological safety" on a team would give you the space to do that without feeling judged or that negative consequences would arise (informal or formal) by acting that way.

You can improve "checked-out" engineers feelings by creating a way for them to express their concerns without worry that they'll be punished for it.

Those toxic teams I'm sure you've been part of, where everyone felt shitty and nobody felt connected to the work? They didn't have to be that way by leveraging "psychological safety", even if "reality" was immutable (also, it's not immutable but we can get to that).
"But these are symptoms not of psychology but of reality."

"But when rubber hits the road most engineers do not have one of either security or control."

Well said
I also think it's not fair criticism. While "precious" can indeed have sarcastic connotation, I don't detect that tone in the paragraph at all.

Yeah, I mean, ultimately my argument is that devs are too lazy to understand documentation, but of course I don't consider myself one of those, so I can't defend the claim that my biased and imaginary sample of devs understands VMs in the same way as your sample.

That said, I will stand by the argument that most people (myself included) are too lazy to understand documentation.

To calculate the angle of the camera you'd still have to find the corners of the paper using some simple computer vision.

You could also just use the corners to compute the homograph transform.

Really depends on the constraints too. If you're going for archival quality scans then maybe it would be better to do it with hardware. At that point I'd just get a way higher res camera than needed, transform and down sample as needed. Would still probably be cheaper than a gimbal.

ITAR restrictions come to mind but I'm not sure if they're the same. For example, if I were to produce a gyroscope with sufficient accuracy the U.S. government can legally prevent me from selling it to foreign entities. Sure my product has excellent civil uses but it can also be used in weaponry (e.g. missiles). Data may have similar implications but I've never thought about this in depth.
different for me. I have a construction mask that has a great filter but it is worn out and doesnt fit tightly anomre. a second whatever mask keeps that first mask close up and creates a better seal
Which is fair but someone motivated, say a vendor that sells those "track customers in your store with bluetooth/Wi-Fi" adds support for this. Sure it's relatively low signal but it also costs nothing.
I recommend adding `--transpile-only` to `ts-node` in npm scripts and any interactive workflows. If you have type checking in your editor or tsc --watch in a terminal you don't need to block unit tests or iterative development while ts-node runs type checks.
Speaking of loopholes, does this affect border control agencies? I read that they can sort of do what they like within x miles of a border
There is a lot of greed driving home sales right now. Every homeowner I know has at least considered making bank in this market. The only thing stopping them is they'll then need to buy a home cheaper and further out or lose that profit.

I'll bet you all my broken iPod Touches that they absolutely didn't, but even did an analysis on how many people are scared by this. The answer was "basically nobody". It's not the companies offering these models who are short sighted, it's the people taking them up.
The Eddie Gaedel stunt was perpetrated by Bill Veeck [1], who came up with so many baseball stunts throughout his life and had many rules changed in reaction to them. Apropos to this discussion is that he is also the last person to buy a major sports team in the US without being massively wealthy.

A few days after that Eddie Gaedel stunt, Veeck did another one where the fans got to decide everything that the team did during the game, by holding up cards to vote.

This article totally neglects the alarm bells blaring in late 2019/early 2020. The Fed lost control of an obscure but crucial corner of the bond market (the repo market), slinked away from Quantitative Tightening with its tail between its legs after a timid venture into normalizing its balance sheet, and was generally starting to brace for impact.

Then, the pandemic and a Niagra Falls of liquidity. Unprecedented in all of American history with the possible exception of WWII.

The country has just fought a war. Wars bring inflation and price bubbles. In the aftermath, prices normalize and the speculators get washed out. And by that point, almost everyone is a speculator.

The question is not whether evidence for bubbles can be found in every corner of the economy, but to what lengths will the country go to keep the music playing.

Fair point. What interest is there beyond the revenue distributed by the DAO? Disney's interest is in marketing the DAO so that customers purchase from it, the authors have an interest in producing content to get marketed.

I'd love to go to sleep an hour earlier, but my 3year old is not asleep at that time :) And he wakes up at 5, so that's great. Maybe when he start skipping his midday nap, we'll start to get some more sleep. Until then, it's dementia I guess.
Many are arguing we are not in a bubble because it is different than the last bubble. What defines a bubble? Is it simply that prices drop from a high after significantly increasing?

If the conditions that they argue are resulting in current prices ease (supply, material, labor shortages are a few listed here), and prices drop, isn't that a bubble?

I guess they could simply plateau and return to "normal" growth patterns.
But note that they're only 43rd in the Order of Precedence for livery companies:

Thanks for the clear and concise way of summarizing my thoughts of the last few months.

I am in a situation where I actually have near absolute safety and nearly no control over the projects. It was even worse in 2020 regarding control after being thrown into a toxic project by a CEO who always touts the motto "no a**holes".

Well when pitching for the biggest budget in the history of the org reality is what counts. Not nice mottos.

So I agree. Everytime I hear this bs about being a team/family/safe place I just think: STFU and pay me. I do my work. Nothing more, nothing less.
I also type elsewhere and copy paste to Whatsapp anytime I am writing something longer than a couple lines. I have also disabled the last seen feature. The currently online status seem way worse than last seen and can't be disabled.
I doubt the limitation is lost on Wyden et al, but there is a political barrier to getting a bill like this passed at all. It's a lot more symbolic to introduce a bill with no chance in hell of passing the Senate than to introduce one that has at least a fighting shot. That is the piecemeal and practical nature of the legislative process. It will be more achievable to get Senate votes to constrain the government's actions than to regulate business. Until there's a stronger shift in the political winds in favor of more robust regulation of the private sector data collection business, the probability of getting over the filibuster hurdle to pass a stronger bill is remote.
Totally Shocked.

I actually believe the contrary to be true: if most people were given well-fitting masks that effectively filtered the air, mask adoption wold be much lower.

Because wearing a properly fitted mask that actually filters the air you breath in and out is extremely discomforting after about half an hour. I've used well-fitted 3M 6500 masks a lot for working with nasty glues etc. Those only filter the air you inhale, and have a very broad silicone lip to distribute the sealing pressure. Still it's a lot more uncomfortable than any of the usual Covid face masks I've tried.

I believe the two largest benefits of mask wearing as currently implemented is catchment of ballistically travelling saliva from sick individuals, and reduction of hand-face contact in all individuals. And for those two, filtration efficiency is irrelevant.
Technological improvements make this so hard to measure, even if we ignore the temptation to game the numbers.

New products, better products, many old products replaced by new ones... it’s so much more complicated than the classical economics textbook case of guns & butter.

Why is this a revelation or surprise? Your employer provides you with equipment and applications not for their benefit, not yours, and I think this is perfectly reasonable. It'd be one thing if GMail cost money, but you can get _your own account_ for _free_. This is a complete non-issue.

Tangentially-related: I was an IT person in a past life and the extent to which some employees treated the company laptops and e-mail as their own was astounding. Light personal use via the browser is one thing, but I would get users asking why they couldn't play a personal DVD after-hours using their work machine, if I could allowlist a hobby-related mailing list to their work e-mail, why I took away their admin rights because their kids needed to install games, etc.
Frameworks shield from footguns like unpredictable DOM modifications all over the place put one over the other.

Their solution is ADUs(accessory dwelling units), which amount to putting sub-par 'granny flats' into the backyards of existing suburban sprawl. That's more or less a bribe to the homeowners to allow densification without changing the fundamental carrying capacity of a neighborhood. Homeowners, who are already likely wealthy due to asset appreciation, are now able to become landlords. Of course this won't change the fact that you'll need a car to commute, so traffic and parking will get worse.
> Well, I think if you're not blind to those things to some degree, you're stuck forever in a best-practices search, which I feel like more often than not ends up implying you have to rewrite your stack.

Can you expand on that? The chain of reasoning is probably clear to you, but I can't follow it.

> For example, I do most of my development thru Hasura now. It writes insanely performant SQL queries translated directly from GraphQL. As a data consumer, you only have to worry about the shape of the data you want, and none of the implementation details. There is one endpoint, and you pass it queries against the schema it exposes. Implementation details are abstracted heavily here, but in a "good" separation of concerns way.

I like Hasura a lot, I've advocated it at a previous company I worked for, and after many months of meetings I got it approved to add to our stack - which was then never prioritized, but that's another story.

> I will never hand-write SQL again. Why would I? My front-ends can load everything in my data model expressively and with type safety thanks to graphql-codegen.

I don't think writing GraphQL is superior to writing SQL, and again you have to think not just in terms of GraphQL but also in terms of how Hasura translates that to SQL under the hood. I am slightly biased though, because I'm creating on a framework to query the db using SQL from the frontend, I'm curious how you think that would compare with Hasura: https://github.com/sqljoy/sqljoy

> Now imagine you read this and realize you work in a completely different method and this answers some of your problems. You may start parallel development, but you certainly can't stop forward progress just to evaluate your stack.

I'm not really sure how this connects to my argument about complexity, although I think the link is clear to you, can you expand on that?
