"but doesn't bother to compare that with the psychological benefit we get from hanging out with friends in daylight after work in the summer, or the psychological benefit of it not being dark when you go home and have dinner with your family."

We have lights. We use them on warm autumn days with friends and family and when folks are sitting around outside playing cards late into the evening. I'm not convinced daylight is needed to enjoy time with friends and family. Sure, you might enjoy it, but it isn't exactly a deal-breaker.

And no, I don't get that "not being dark when I go home". I'm in Noway, and if you work first shift - or heck, even business hours - you'll only see sun in December on your lunch break. Again, though, we have lights, and they are a pretty wonderful thing. Outdoor heating and blankets extend outside time too.

Not just that, but folks with a later rhythm are going to suffer more. I'm going to guess especially teenagers (in general) will suffer, as doctors already complain that school is too early: Permanent summer time pushes it an hour earlier.
That's not always true though. Although WhatsApp is very popular here in South Africa, I use iMessage most of the time because most friends/colleagues/family have iPhones.

And honestly I have switched off notifications on WhatsApp (I cannot recommend this highly enough!) so that's the only quick way to reach me. I am sure others do the same.

I suffer from this too (only formally diagnosed with sleep apnea though) and found that 0.5mg of melatonin about 20-40mins before I want to go to sleep has helped me align my sleep cycle to a 24hr schedule. I also get a consistent 8hrs registered on my CPAP so it doesn't seem to interfere with my sleep quality/duration either.

I buy melatonin that comes in 1mg pressed/powder pill form and just bite it to split it in half and toss the other half back in the bottle.

I've been doing this for 2 years now and have never had to change the dose. At one point I even considered seeing if .25mg would be sufficient but depending on the brand sometimes the pill crumbles up too much so I stick with .5mg. I've used Nature's Bounty and Webber Naturals and both brands seem to work the same for me.

I really wish I had figured this trick out a lot earlier in life as it would've saved me from missing out on a lot of opportunities in my career.

(more detail about my experimentation below)

Before I discovered this I tried everything from reducing screen time before bed, cranking up night mode in flux/redshift, abandoning coffee/caffeine entirely, working out earlier in the day instead of evenings, etc. _Nothing_ worked for me - my brain would remain wide awake and I would have to stay up until 5-7am before I even began to feel tired (where I would have to wake up between 10-11am for work).

I had even tried melatonin before too but it was a 3mg pill and it would produce very erratic results in my sleep quality. I'd sometimes wake up drenched in sweat or wake up feeling very groggy for hours so I figured melatonin just wasn't for me. It wasn't until I came across some advice on /r/n24 or /r/dspd to try .5-1mg of melatonin that I decided to try again (IIRC it was a post about how doses >=2mg can actually result in melatonin overdose and result in the types of symptoms I was observing - TBH I didn't really bother verifying that info and just figured I'd try .5mg and see what happened as I was desperate for a solution).

And for the record, with this approach I haven't had to make any other modifications to my daily routine. I continue to lift heavy in the evenings and drink 1-2 cups of drip/espresso every day.

The only situations I've noticed where this trick falls apart for me are:

1) if I ever try to push past that 20-40min period where I start to get drowsy, it results in me being awake again. This rarely ever happens and I usually just end up sleeping about an hour later. I make sure to take the melatonin just before I begin flossing+brushing and get in bed right after

2) for some reason drinking a can of coke/pepsi in the evening will keep me wired awake all night. I've had cups of coffee in the evening rarely which never had the same effect, but coke/pepsi will...

Anyway, just thought I'd share since this made a huge difference in my life - maybe worth trying/experimenting.
>Why not just get up with the sun and go to bed with the sun.

Where I live that would give me about 2 hours of sleep in Summer.
That isn't really the issue. The issue is that you have to use Apple's store. There's no alternative.
> Besides, if you allowed more stores, nothing’s going to get cheaper for the customer

If you allowed more stores, they would have to actually compete to attract customers and prices are a fairly common way to do that. It's exactly what's happening on the PC video game markets with the Epic Store having giveaway and promotions.

So yes, it's pretty much a given that if you allowed more stores it would result in lower prices for customers.
I think Apple is in the “real estate”/rent business here. if you compare that to how big malls operate it’s pretty similar. They take a fixed fee plus a cut from the revenue in exchange for foot traffic.
I'm in Norway. While the sun technically goes down, it just goes barely below the horizon so we just have a few hours of civil twilight and if there are a few clouds, a sunset that lasts for hours until the sun comes back up. I can read outside so long as it isn't too cloudy - and barely need light to do so if it is.

It is pretty glorious, though some folks do need to darken their bedroom to sleep well - especially immigrants.

Reviews for Visualizing Citibike Trips with Tableau Course
This is a very short project-based course that will help you learn all the basics of how to use Tableau Public software to visualize Citibike Trips Dataset. You will be taught to gather the data provided by citibike and then visualize them properly. As the datasets will be of great volume which means that you need to focus greatly on this course to understand all the technicalities.
Mark Manson actually wrote a great article on this: In defense of being average => https://markmanson.net/being-average
Afaik Unity royalties are based on revenue, not profit. Balance sheets are not difficult to mascarade, revenue is much harder to hide.

Though I agree a minimum revenue threshold would make sense. But that's not apples strategy. Their strategy is to subtly charge the massive amount of indie developers (developer account fee) and take 30% from the get go.
To argue for this workflow: the mutex is soft (social) which is a good thing, sometimes ppl do not reply on time and you need to move forward. For having new ideas/paragraphs after sending out, you either inform the colleague to hold it until your done, or you send a paragraph and ask him to merge it.

The mail allows you to see all patches, sometimes 'clean slate' is done by accepting all changes. While this sounds like a problem in theory, in practise its not.

I agree that things can be better somehow, but it is really difficult to see any solution which is at least 10% better. The current workflow also has the advantages:
- data is as safe as your filesystem and email system together
- Word file is generally not considered a vendor lock-in
- everybody understands the workflow
- nobody can block the workflow (like not checking in again with sharepoint)

> whereas iOS has somewhere around 25% market share.

I dont think that is the point, Apple has 100% market share on its devices and its using its dominant position in that market to make that market anticompetitive (as per Epic)

Apple also has secret deals with other big companies where they can negotiate the commission Apple gets, apparently they did not give such treatment to Epic and other devs
You can also get a trajectory with a stack of CCDs where the trajectory is not in the plane of the CCD. Actually the stack may be very high with quite some distance between individual CCDs, because you need trajectory in and out of detector elements like calorimeters that are a few meters in size. Also, trajectory may be bent because of the particle's charge and a magnetic field, for that you need a large distance to get the "amount of bend" if it is small.

But yes, there always is an efficiency, precision and identification tradeoff.
I think that's actually a rather poor discussion, revolving around what is or isn't "ad-hominem", or which unimportant details of the history of WASM are inaccurate, or what the name of things should be.

All of the technical concerns raised by the post are either left unaddressed, or deferred to future extensions of WASM. In other words, the author must be correct in his analysis and the standard has made questionable trade-offs from the outset.

I can think of at least one reason why you might want a register machine: Not every platform is going to use or allow JIT, and a register machine would perform better here, i.e. like Dalvik in the early days of Android.
I have literally no idea what all of the stuff in the article means, but it sounds like the whole thing was broken from the start.

If someone can take the transaction you just sent and somehow jump in front of you to execute the same one, your system seems fundamentally broken.

It’s because the flow of electrons driving current is mostly used only in one part of neurons: mitochondria. It’s used to generate ATP, which is the actual currency of energy in cells. This in turn powers systems that send and receive ions that are generally positively charged (why this is, I’m not sure) for neural communication.

So, while reading electrical signals is possible, returning them is tough because you’re so far removed from the language of the neurons when using electrons.
Hello, colleague!

For folks who might be interested in more details on this: The _cross section_ allows you to quantify the frequency of a specific event occurring in your chip when bombarded by a specific particle (or class of particles). For example, in a case of an SRAM, you might want to calculate the cross-section for bit flips due to 24-GeV protons. The result that you get will be in units of cm^2; you can also interpret it as the physical surface area of the chip, multiplied by the probability (0..1) that any 1 particle passing through will trigger an event. Let's say you measure a cross section of 0.01 mm^2. Then if you expose that component to a flux of 10^3 particles/cm^2/sec, you will get an average of 1 event every 10 seconds.

The cross-section is only valid for one combination of the (event type, particle, energy) tuple. But often in dosimetry, errors on the order of 20% are acceptable, so we can "abuse" the results a bit. Within one manufacturing lot of chips, the cross-sections should be reasonably consistent. Typically you would estimate the mean and variance by measuring a few samples from the lot.

Then, to accurately measure a radiation field using these findings, you would generally need to measure the flux of every particle-energy combination separately. This is impractical, and for SEE* concerns we generally get away with distinguishing thermal neutrons and high-energy hadrons (which are separated by several orders of magnitude in energy). For this, it is sufficient to have 2 types of SRAM where each has a dominant cross-section for one of the particle classes of interest.

To measure the type of radiation that causes long-term gradual damage (TID) such as X-ray and gamma rays, you would use a different principle of measurement altogether (RadFET, P-i-N diode, floating-gate dosimeter...)

Radiation measurement can be fun!

What if you're designing for OLED panels, where black is a stand in for "pixel off", which saves power and can help to hide bezels or (as with the default iPhone X Wallpapers) a notch.

Sure, it's not trivial to get right, and it should definitely not be used outside backgrounds, but never is a harsh word.

>"There have been times when I was willing to suffer some small harm so that I could punish someone else who deserved it"

Is this really a dark trait? I admit to thinking this in the past but now I've learned to let things go and let someone else deal with it. I have sometimes thought about this and wonder if this is the darker version. I guess "correcting" someone is better but often these can be such obvious things that you'd think people would know anyway.
It's a great analogy, that's why we banned slavery altogether and allowed personal declaration of bankruptcy, we learned from history and it took us centuries to get the slave drivers to comply.
Low doses of melatonin can be really helpful, especially if people have tried all the "sleep hygiene" steps and that's not working and they don't need a z drug yet.

One of the problems of melatonin is that in some countries it's sold as a supplement not a medication, so the regulation is much less strict.

The dosing varies so much, even in product labelled as 1 mg.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5263069/

> In this issue of the Journal of Clinical Sleep Medicine, Erland and Saxena systematically analyzed the actual melatonin content (and presence of contaminants) in 31 melatonin supplements purchased from groceries and pharmacies in one city in Canada (before countrywide OTC use of it in Canada was banned). Their findings herald what may also be true in OTC melatonin supplements marketed in the United States. Melatonin content varied from an egregious −83% to +478% of labeled melatonin and 70% had melatonin concentration ≤ 10% of what was claimed. Worse yet, the content of melatonin between lots of the same product varied by as much as 465%.3

> The most variable sample was a chewable tablet (and most likely to be used by children). It contained almost 9 mg of melatonin when it was supposed to contain 1.5 mg and also exhibited the greatest variability between lots (465% difference). The lowest melatonin content was −83% compared to its labeled value in a capsule that also contained lavender, chamomile, and lemon balm. Capsules showed the greatest variability between lots. Liquid supplements surprisingly showed generally high to median stability with low lot-to-lot stability. The least variable products were those that contained the simplest mix of ingredients, generally oral or sublingual tablets with melatonin added to a filler of silica or cellulose derivatives and were the most reproducible. The last disturbing finding was more than a quarter of melatonin products contained serotonin, some at potentially significant doses. Serotonin is a breakdown product of melatonin metabolism but could have medicinal effects and should be taken without oversight. In short, there was no guarantee of the strength or purity of OTC melatonin.
Just because we are forced to accept such limitations on some devices, that does not mean that it is necessarily acceptable. I own a PlayStation because I want to partake in entertainment exclusively available on the system. That does not mean that I don't get to hate the fact that it's a locked-down piece of crap. I really think they should be forced to open up the platform and not have any barriers for people who want to execute arbitrary code on hardware they paid for. The same should also be true for all computing devices - why should you not be able to change the software in your fridge? It's yours, and the manufacturer should be forced to respect that or very explicitly state that you are actually renting it and do not own it if they don't want to open up the hardware to its owner.
I would second the other reply. While it might seem natural to get good at Chess in a chronological way (early, mid, end), its actually the opposite you want to do. You need to know where you want to go (what endgames are good for you) before how to get there. As far as openings, Id learn 1-2 openings for white (Ruy Lopez and Jobava London for me), and then two openings for black (one for e4 and d4). Id learn the first 15 moves or so and all their variations in case your opponent makes a mistake. Youll win a lot of games that way and then just play conservatively until you are near the end and up a piece.

Yes you can pay for promotional spots on both mobile stores and steam, but that is not to say that they are remotely similar in terms of discoverability.

Discoverability would include things like a recommendation algorithm but also filtering features, promotional spotting, social graph relevance (do my friends own this game? do they want to?) and general UI accessibility, to name some factors.

Steam has put so much work into making sure users can find a title (regardless of that title's marketing budget) that fits their arbitrary preferences that they are now LEAGUES ahead of mobile stores on that metric.

One example that is easiest to point out is the main carousel (and entire front page) of the steam store. Everyone's carousel is customized to their profile and will show both old games and new based on an algo that weighs your preferences against a title's relevance and performance metrics.

The irony that google, a company that made its name in SEARCH, has an app store who's discoverability is so abysmal that i can't find certain titles without explicitly typing in the name or digging through 100s of "more titles like this" lists is not lost on me.

It's just really bad. The game categories are too few in numbers, and there's no tagging to speak of so finding something remotely hybrid is a pain and the categories themselves have become unhelpful.
The problem is, people misinterpreted it in all possible ways, the result being low contrast between the background and foreground text you can find everywhere. The second culprit after the font being too small.
This is just bad advice.
From an artist's perspective, folks just have to realize why they are making the choice. If you want a painting to look natural, by all means - avoid black most of the time. Black, like grey, is generally something that has color to it where a standard black paint really won't have the depth.

But not everything needs to look natural. Black text? Just fine. I do a lot of abstract art: Black works well. I'm not going to give up black ink linework any time soon.
At least Apple TV supports this feature, even if it's off by default.

Google simply "decided" for Chromecast users that 60 Hz is fine and that nobody needs 24 fps or 50 fps content.
Maybe let's bite the bullet and try chemical power? Natural nanobots (cells) work fine powering themselves off ATP, so why couldn't human-designed ones?
I've seen this described numerous times. Here is a quote from a research company called Navigant[0]:

"Tesla continues to make high-profile promises, including having one million robotaxi-capable vehicles on the road by the end of 2020," Navigant's report reads. "However, the performance of its systems remains inconsistent and its products do not match its proposed mobility business model."

My father in law is a Vietnamese immigrant, came here after communists destroyed his country on a fishing boat. He’s now a retired millionaire!

My neighbor is black, and she drives a $100k+ Mercedes! Country club golfing and sailing type.

My point is, arbitrary assumptions based on race are totally meaningless in 2020. There are people in all social strata of every race. Giving a leg up to someone for being XYZ is dumb - it reduces complex people to simple labels that define how victimized the woke left says they should be.

If we want to talk about giving government assistance to people in poverty regardless of race, I’d be much more amenable. There will be correlations to poverty and race but I think we all agree Oprah and Michael Jordan should not be getting handouts.

As it stands the identity politics movement is ideologically inconsistent and is focused on driving people apart and re-segregating us. This is a movement doomed for failure. We should instead be eliminating our superficial differences and moving beyond bankrupt social justice theories that reduce individuals to mere labels rather than intelligent, thinking independent people with their own agency.
From the bullet points that start the article:

Do you realize that what you’re describing is essentially a general AI?
But you don't need to pay for such feature. It's called approved software, with signatures from multiple authorities you can get all sort of filtering you want. That's just not what the manufacturer wants, they want to be the sole authority, treating us like kids with restriction and cows at the same time with this 30% cut.

This might all be true for paintings, but on a screen, #000 isn't black. It is usually a dark gray, depending on the backlight and contrast of your screen. And even with OLEDs, it might be darker, but it isn't really black. So imho, no need to be afraid of black for screen design.

As for print, it depends on the process. Anything that composes colors from CMYK pixels will look ugly and blurry if you do not use pure colors e.g. for fonts at low resolutions or close up. Just compare black fonts and dark brown or grey fonts out of a color laser printer for an example.

So no, only avoid black if it is really black you are avoiding and if it doesn't cause other problems.
I had an idea for an article, didn’t really care about where to put it and I decided to give Medium a shot. I didn’t know it would be that bad.

There’s no way to turn off auto-formatting in Medium editor. No way at all - support confirmed it. Dashes, quote marks and ellipses in your article will be placed only in a way Medium wants them to be. So, for example, if you decide to write in a language other than English and want to surround your dashes with spaces — like this — according to traditions of this language, there’s no way to do it in Medium editor. Even if you try to do something smart with clipboard, your efforts will be overwritten on save.

This is a clear example of a software that tries to be smarter than its user and fails.
