I didn’t read the article but I’ve worked for one of these companies that was a startup and have a local mattress company as a client. So a little perspective.

These companies are all marketing companies. There is no “science” they literally get rolls of foam from foam makers, throw them on in layers and try to find the right combo. I was there, I’ve done it myself.

The companies that end up winning have fantastic marketing, like purple, or were early, like Casper.

Markup for foam mattresses in general is close to 2000%. Average foam cost for a king mattress was <$50. The old school mattress companies are close to The same which is why they have stores on every corner.

The industry is dirty as hell and as cut throat as they come.

As far as the returns, a reputable company will send the Salvation Army or local equivalent to pick up the mattress and it becomes a tax write off for the company. Otherwise like others have said they will tell you to keep it. No sense bringing it back to the warehouse and in a lot of places it is illegal to resell a mattress.

AMA if you want. Fascinating industry.
I teach at the high school level. Everyone knows this is true and some districts in my area are changing to a later start time; however, there is a great deal of institutional momentum working against the change. Primarily due to primary school start times, bussing schedules, and athletics.
The positive spin was removed, and that's also why everyone reading can pick it up so fast. If it wasn't so well written, another author would had just said that DO has plans to be profitable.

When the CEO said "profitability" to the reporter, he challenged it by putting as "loosely". The reporters is informing us, but also making it a point that the CEO alleges something that is not consensus can be considered profitability, he is impartial in displaying the information, but making it clear it's sketchy. It's great writing actually!

It's a matter of incomplete metrics. What impact do later school start times have on parents? How about parents' workplaces, especially for shift work? Regulatory capture means convenience for businesses is likely to trump children's health and performance.
They'll just call it "sports mode".
Cherry picking by looking at males only, which somehow didn't make it into the title here in what I'm sure was an innocent oversight. It's also flat out lying by saying "earn same" - the tweet only claims earning enough to pay for typical household expenses - the typical household buys a lot more things than they did in 1985.

Title is heavily misleading and inaccurate and should be changed.

See https://twitter.com/Noahpinion/status/1230547825122889728 for some other comments on the thread
I think the comment was a little tongue-in-cheek -- like FizzBuzz is a problem without much inherent complexity, but you can certainly you make an overly complex solution: https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpris...
I mean, "casually state talking points as fact without citation" is exactly what the original commenter did, so I don't see why the responder should be held to a higher standard.

There's a reason why we don't like political topics on HN, and this thread is proof.
It's difficult to fund and maintain those things if capitalists offshore production and don't repatriate profits.

Similarly, it's difficult to control costs on social outlays if the population expects a 4-bedroom ranch house with miles of million dollar pavement and other connecting services, cheap goods, a platinum health insurance plan (or at least the prospect of one--I don't think many ACA opponents realize how crappy their pre-ACA plans were and how precarious of a situation they were in and may be in again now that coverage mandates are no longer being enforced), etc.

The politics of the United States is in many respects like that of much poorer, more dysfunctional countries. The poor, working and middle classes are promised the stars and get scraps; but they vote based on the promises. And to the extent the promises are delivered, they're paid for with mountains of debt. We've even convinced ourselves that "deficits don't matter" (literal mantra of the GOP), ironically right at the moment (dwindling debt purchasers) when there's a regression to the historical mean.

Democratic socialism isn't viable in the U.S. The U.S. has all the bad qualities of conservatism and, increasingly, leftist populism, with little of the restraining characteristics of either.
Interesting idea. Couple of things...
* coverage map?
* app not available for in us Apple store
* android link fails
* keeps showing in Spanish, no matter how many times I changed to English. It also sent my sign up email in Spanish...
* no details on how to create a network
* how is the connection made? Is this hotspot 2.0? Some sort of cert? What do I need to share my connection?
This is well known, but it also has impact on lots of other interconnected issues. Such as parents work schedules, that effect stability, that effect students learning as well. It will also impact school budgets, which then influences what kind of supplies and teachers a school gets, which also has a big impact on learning, and on and on and on.

Not saying we shouldn't do it, I just feel like sometimes we see an idea that would help things and then jump to, obviously there is no reason not to do it, it must be evil <insert bogyman here government, corporations, lazy teachers unions, Illuminati, leprechauns>. We must remember we live in an incredibly complex system and pushing for changes in just one part will have ramifications that must be considered downstream.
I believe Riksbanken want it to be decentralised though. They don’t want to have to bother with Know-Your-Customer stuff. I believe they don’t want to have to store personal data.
At the same time they don’t want it to be anonymous.

That’s why a solution where the commercial banks drive the chain, and keeps the KYC, allocating “anonymous” blockchain addresses, or accounts at the riksbank, has been proposed. The customers bank know the customer, the Riksbank does not. But the Riksbank, can still issue interest directly on the currency directly to the customer.

There are several ways that the nodes, or commercial banks, or whoever it might be, can make the whole think pseudo-anonymous for the customer. Would also let commercial banks offer services around it, making it easier to get the banks on board.

> How would I tell if it wasn't changing the backlight itself?

With the exception of OLED (no idea if laptops use that stuff yet), when the LCD is fully opaque on i.e rgb 0,0,0 the backlight LED will still bleed through - Modern LCDs are much better at blocking out the LED than they used to be so it's not always obvious in a well lit room.

If you reduce the brightness to 0 with xbacklight and then sleep the computer: The display will perceptibly dimm much further as it turns off (since this guarantees the back-light is turned off). If you use sys/class method it's possible to turn the backlight completely off so that there is no perceptible difference when you sleep/poweroff the computer.

On the older LCD panels when poor contrast ratios were common it's very obvious that xbacklight is only affecting pixels. I've never seen this tool affect the actual backlight but maybe it does have that mode?

Your script is essentially using the same method although in theory it's not as portable since the path is exact and it uses a hardcoded interval, you may have to tweak both for different machines. My one uses bash path expansion that is more likely to match other path names, and derives the interval from the max value... I honestly haven't looked at the variety of possible paths for /sys/class/backlight and max values so maybe I was over anticipating when i wrote this.
The point is that there is an aspect of the circadian rhythm which can not be circumvented simply by going to bed earlier.

Is this a joke. Miami is actually known to have the worst inequality he country. [0]

As the articles points out there are 30 billionaires but "Miami-Dade’s middle class is relatively small and shrinking steadily, the report found. Just over 43 percent of Miami households qualify as middle class, the 11th-lowest proportion among the 53 U.S. metros with populations of more than one million. And that proportion has shrunk significantly over the decades"

That doesn't even address the fact that the HN crowd will never be owners of the bentleys and rolls-royces, billionaires have unattainable wealth, a FANNG engineer has to work for centuries to be even close.

Agree completely. I've been an exec for multiple low 9 figure hosts and always imagined they were larger by a wide margin.
I had a split schedule in 7th and 8th grade, from 11:30am to 5 pm. Best time of my childhood education in terms of awakeness and alertness. High school was the opposite, horrible, had to be on the bus by 6:45am. It was dark and raining/snowing sometimes, we hid under parapets at nearby houses sometimes for shelter. I remember cursing the Board of Education during those times, they didnt have to suffer through the stupidity of their decisions.
> 10/ When we say "inflation-adjusted wages look good," we are actually saying "if you could take your wage back to 1970 and spend it, you'd be better off than you were at the time with a 1970 wage." I mean, maybe that's interesting. But it doesn't describe lived experience.

Isn't more like saying, you can buy more units of 2020 "consumer goods" with a 2020 wage than you could buy 1970 consumer goods with a 1970 wage? His point is just the definition of inflation: $1,000 in nominal dollars more valuable in 1970 than in 2020.
I'm not sure I would count on that :-) I'm also not sure how I feel about the foam mattresses. That's one type of mattress I don't have a lot of experience sleeping on and my initial reaction in the store was it was "different" to a degree that I wasn't sure what to make of it.

Also, I tend to be hot generally including when sleeping. From what I've read, a foam mattress may not be a great choice given that.
There should be a line somewhere between curbing abuse, curating content, and promoting ideology. But I personally don’t feel comfortable or qualified to decide where that line should be drawn. There must be some point between USENET and the NYT editorial section where the publisher becomes liable for the content they promote.

If capitalists evade taxes, we will claw back their profits. We will contain the costs of public goods using technology, transparency, and sound governance. Defeatists have no place in building the future.

We shall agree to disagree. See you on the campaign trail, the floor of Congress, or on the picket line. I see no other path forward for delivering compassion and a reduction of suffering at scale. We tried American Capitalism, and it has failed us miserably.

The abstract does a good job of summarizing why this matters: "During puberty, the adolescent circadian system naturally delays the onset of sleep to a later time. One reason for this is an apparent lengthening of the circadian period during the teenage years (1), which typically leads to a later onset of the biological night relative to the light-dark cycle"

Not in the economic sense where a free rider under-pays meaning someone else has to be over-paying.

If everyone is underpaying then it isn't free riding; it is just sensible business.
Well, I don't see how you can make progress without formulating theories (more correctly, hypotheses).

I think the problem is when people become attached to a particular hypothesis. Many people seem unable to accept that they only have sufficient information to assign probabilities to different hypotheses and instead always assign probability 1 to their favorite hypothesis and 0 to all the others.

Hi, thanks for the invitation!

How can you be sure that the synthetic data you generate does not bias the architecture search away from the optimal solution for real data in a way similar to how early truncation of learning biases architecture search towards quick learners, and possibly away from peak performers?
Yes that's correct. As long as you service the debt you are basically just paying an interest rate to use additional funds but retain future upside for shareholders.

Versus selling equity you can burn through the capital without repercussion however you are also giving away future upside.

Also the benefit to a debt is that banks want to be repaid. The last thing they want is for the company to go out of business so there is a much larger review of the financials of the company. This forces good accounting practices as well as good spending behavior.

Versus when you sell equity you don't really have those same financial controls and as has become more and more common especially in the last few years companies then go and spend that capital inefficiently to grow their revenue base but never get their costs under control.

Then you end up with a business model that doesn't work. The most recent example of which is Casper. Which raised well over $300MM in equity but is still losing $60-80MM a year and required an IPO to continue financing their suboptimal business model. The investors here got burned because the last private valuation was $1B and now that it is publicly traded it is $419MM.
> SmartTV

From what I've seen about Smart TV's, I'm better off not allowing them to ever connect to the Internet. Forgo all the "smart" features and just use a Fire TV stick, Roku, Chromecast, etc.

My current TV is an 8 year old 46-inch "dumb" TV, but I plan on upgrading to something bigger later this year, and it looks like my only options will have Smart features, but I already use a Fire TV stick and a RPi, so I don't think I need the smart features.

>Free speech states that a state isn't going to prosecute you directly for whatever you may say. But that doesn't mean you are free from the consequences of what you're saying.

If you are punished by the government for what you say, are you not being prosecuted by the government for what you say? If we say that all one needs to do to be punished for saying the wrong thing is to enter into an agreement with another person, what is to stop Facebook from adding something to its EULA saying by using the services you are agreeing to not say anything out of line with what Facebook wishes?

It seems like the end result of this rationale is that we allow the government to enforce private agreements that compromise speech. Effectively meaning you can sign away your First Amendment rights.

The whole "doesn't mean you are free from the consequences of what you're saying" is meant in respect to how other people are treating you, not how the government is treating you (regardless if it is on behalf of another person).
Oracle winning will not destroy the tech industry, bring innovation to it's knees, or any other crazy apocalyptic concept people have.

It'll mean Google will pay a huge penalty for very willfully stealing Java when they knew they were supposed to license it, and other companies will be a little more explicit about getting licenses squared away. Reliance on open source APIs and platforms will probably go up, and license compliance with terms of GPL and the like will be taken more seriously.

So that second quote doesn't really support the claim that temperature has no relationship to bleaching events. It only implies that bleaching can happen exclusively due to pollution.

The first one is suggestive, though! At least in that specific region. Of course, that paper doesn't go so far as to make the claim you're making, only stating that "reducing the risk of coral bleaching, disease, and mortality under the current level of temperature stress".

But it does indicate that pollution is an extremely important factor in bleaching events

Given Australia has recently been experiencing repeated mass bleaching events over a very large area, and given you claim that that affirmatively is not associated with ocean temperature changes and is only associated with pollution, then you should be able to provide evidence that pollution levels have significantly and consistently increased near the Great Barrier in correlation with those events.

I’ll reiterate the margins. Based on your account, my suspicion is only reinforced, actually: if you had big enough capacity problems to need a $3 million round to buy gear at the size you were in 2013, I’m mystified that your margins were that low. Was that the $10/month decision biting you (notice Linode waited) or the far bigger headcount? How far Linode got on basically two technical employees, including the founder driving gear to the datacenter in the back of his Ridgeline, would seemingly surprise you, as would when the revenue was sufficient to sustain ongoing server spend. Linode ran out of capacity ALL THE TIME. It’s a HUGE market. Turning away a customer is not fatal in the slightest.

One server, three months, paid off. Two months profit, next server. Linode leased in the beginning! I’m not arrogant enough to assume I could do it better, but I do know the technical side very well, and with an American Express and a decent funnel of people you know you can be profitable in under a year at this. The fundamentals of what is basically a rack-and-stack game, and what is possible with $400 million of capital... it just doesn’t align with how I’d expect a VPS provider to operate, but you’ve convinced the checkbooks to keep it going, I guess.

I actually compare DO and Linode’s approach all the time as an example of VC methodology versus patience. The $400 million raise game is not appropriate for the VPS space. It’s a market literally defined by bootstrappers.

If you hit $1 billion ARR in that market, by the way, I’ll shut up. Knowing what I know about the market, that sounds about as likely as DigitalOcean colonizing Mars, but I’ll applaud you if you do it.

Agreed that free cash flow can be misleading some cases, and digging a bit deeper helps us understand what those cases are.

Free cash flow and net profit should equal each other if summed up over the entire lifetime of a company.

The trickiness of course comes in the timing of when revenue and expenses are recognized. Whereas a large capital investment hits free cash flow the same year, it only impacts net profit over the course of its depreciation.

Free cash flow can be misleading for companies that require a disproportionately large capital investment upfront but negligible expenses thereafter. This can be illustrated by taking an edge case to the extreme: Let’s say a company required a $1,000,000 capital investment in Year 1, $0 in subsequent expenses, and brought in a piddling $1 in annual revenue until it shut down in Year 10. The company would have been free cash flow positive in Year 2 through Year 10, which would be misleading because in fact the company was never profitable and also had negative ($999,999) free cash flow in Year 1.
