Long article. Here is synopsis:

- In 2008, a two-year study found that drinking water with chromium-6 caused cancer in laboratory rats and mice.

- The California scientists set a public health goal of 0.02 parts per billion in tap water, the level that would pose negligible risk over a lifetime of consumption.

- But in 2014, after aggressive lobbying by industry, state regulators adopted a legal limit 500 times the public health goal. It is the only enforceable drinking water standard at either the state or federal level.

- The test data estimates that water supplies serving 218 million Americans – more than two-thirds of the population – contain more chromium-6 than the California scientists deemed safe.

- The article has nice interactive map that lets you check if you are drinking contaminated water (Phoenix is really bad).

- EWG estimates that if left untreated, chromium-6 in tap water will cause more than 12,000 excess cases of cancer by the end of the century.

- The article then describes shenanigans the industry was involved to sabotage raising this public health concern (like retracting a study of a dead scientist), stalling EPA risk assessment, etc. Very entertaining read - worth a movie or a documentary.

curious as to what you mean by that. I definitely have an ad-blocker running on my phone (android)
Good question... Calculus? Of course it has a long history with computing, but I would say that probably less than 10% of programmers outside scientific fields use any calculus. There is calculus in machine learning but I think that counts as less than 10% of programmers, and it will probably become its own specialty separate from programming in the coming decades (to some extent it is already)

From what I know of topology, you use logic and algebra as tools to learn about it, just as you use logic and algebra in computing. But you probably wouldn't use topology to say anything about computing.

Number theory is relevant to crypto, but I would be hard pressed to say it is practical for programmers in general. You could probably have a pretty long and successful career in programming without knowing basic things like what a prime factorization is.

Don't try to do this by visual pattern recognition. Do math. There are plenty of statistical tests that you can use, use them. Any of them is better than looking at a graph and guessing from the shape.

If you want to try to understand what is going on, learn the Central Limit Theorem. That will let you know how fast the convergence is to the laws of large numbers. (There are two, the strong and the weak.)

Every so often there'll be a story about how there's a thing that "doubles" your risk of some type of cancer. Which turns out to mean your chance goes from 0.0000001% to 0.0000002%.

In much the same way, moving to SF may "double" your chance of winning the startup lottery. And buying two actual lottery tickets gives you twice as many chances of winning the jackpot.

It looks like there are quite a few options for your device: http://forum.xda-developers.com/s7-edge/development . On further investigation, there is a wrinkle - if your device has the Exynos chip, then your options are pretty limited while Snapdragon devices are well supported: http://forum.xda-developers.com/s7-edge/development . Unfortunately it looks like it won't be a slam dunk for your particular device.

I'm surprised Google Duo hasn't become more popular. It's a great cross-platform video chat app. I especially like the feature where you can see the other party before you answer their call. I have taken calls because of that feature that I otherwise wouldn't have.

It's better than FaceTime because it works on Android. It's better than Skype and Google Hangouts because your cellphone number is your identity; you don't have to log in with any usernames or passwords. Extremely low friction.
I wasn't aware of it, thank you :-)

Yes, you are absolutely right ("Pilot's handbook of aeronautical knowledge", "Helicopter flying handbook", etc.).

That said, rational numbers and twelfth root of two etc. aren't exactly what musicians or composers would be thinking about, but rather scales, intervals, chords and progressions.

If you take a consistent low dose of Adderall at least, there should be nothing wrong with taking it every day and might actually be preferable that way, otherwise you're in for a rollercoaster effect.

The longer you're on though, up to a point at least I imagine, assuming the dose is consistent, you will have a greater withdrawal period that will really suck compared to if you only use them recreationally, which I consider to include situations where you take them only when you need them, such as all nighters; that definitely falls under recreational usage.

It's cool to learn recognize how simpler math concepts apply to computing. Ie, associativity allows for map/reduce
The Google Assistant integration is arguably the killer feature of the app. End-to-end encryption would delete it, thus it is not the default.
I think the point was revealed in the first line. "A record of nootropics I have tried, ..."

I don't think it's supposed to be looked at as a one shot article or blog post, but rather a collection of notes / anecdotal evidence / experimentation.
Isn't the main feature of this (smart reply) something that can be easily implemented by other messaging apps? And the stickers/emojis and Google Assistant are already available in other apps. Granted, Google has the power to integrate things really well and make it a premium experience that can win users over. Also, how does this relate to Google Hangouts/Gmail Chat? Lots of questions so it will be interesting to see how this will turn out.

How does this company plan to make money from this? I tried to browse through all the pages and I am not seeing it.
it's not always-on end-to-end encryption because the standout feature is the google assistant. literally the whole selling point of the app is that google is always listening in. If you want google's assistant to not be continually monitoring your conversations, then allo is definitely not the app for you.
Circa 2014, highlights below: http://www.slate.com/articles/technology/technology/2014/10/...

"These maps contain the exact three-dimensional location of streetlights, stop signs, crosswalks, lane markings, and every other crucial aspect of a roadway."

"But the maps necessary for the Google car are an order of magnitude more complicated. In fact, when I first wrote about the car for MIT Technology Review, Google admitted to me that the process it currently uses to make the maps are too inefficient to work in the country as a whole."

"To create them, a dedicated vehicle outfitted with a bank of sensors first makes repeated passes scanning the roadway to be mapped. The data is then downloaded, with every square foot of the landscape pored over by both humans and computers to make sure that all-important real-world objects have been captured. This complete map gets loaded into the car's memory before a journey"

"The company frequently says that its car has driven more than 700,000 miles safely, but those are the same few thousand mapped miles, driven over and over again."

"Chris Urmson, director of the Google car team, told me that if the car came across a traffic signal not on its map, it could potentially run a red light, simply because it wouldn't know to look for the signal."

Google's entire business advantage is based on cloud. I welcome anyone to prove that this has changed.
My experience with modafinil was quite distinct. If I started a task I could stick with it for a long time. However it was indiscriminate as to the task importance.

It gave me a much narrower focus - when I was playing pinball at a local bar my scores dropped because I was narrowly focused on where the ball was, rather than where it would be, and I had to consciously force myself into using my peripheral vision.

Another example: I was practicing hand-writing a different (non-Latin) alphabet and had a practice book. Usually I could do one or two pages and then stop for the day, wanting to do something else. On modafinil I did about ten pages' worth.

I was waiting for Duo and didn't even know it launched. Maybe more marketing is required.
It's absurdly easy to get. There are even dedicated online sites like ModafinilCat that make the whole experience like buying on Amazon. It is a bit pricey since it's coming through customs from India typically, but still affordable if you just need some to take during crunch times.
Looks like this is an attempt to do the same thing that iMessage has done for iPhone. If Apple released iMessage for Android it would probably lay waste to most other messaging services. People will pay to get upgraded to the blue bubble.

Perhaps, and I wouldn't know from first hand experience trying it myself, but I imagine it is almost guaranteed to be safer than smoking. For reference on that matter, my mother passed away a while back from lung cancer induced by smoking (small cell lung cancer).
Next time I see someone mention how great their monolithic repository is I'll ask how many chat applications you have to checkout before you can code at google.
Because Hangouts is a bloated POS? Everyone I know who works for Google states this (and I can concur from using it at work).
The Marginal Advantage
Interesting, I take 3 or 6 mg per night about an hour before sleep, I've never experienced that but it does make my dreams more vivid and memorable and I wake up from the occasional nightmare as well.
I'll use everything Google, but Duo has been the most stupid video chat app I've ever used. That's because in countries where the common household internet is still not that fast, it 'aggressively' pauses (completely removes) the video for long intervals in every few minutes citing slow connection. That's a frustrating experience. I generally get around 10-12 Mbps speed (which is on the higher side in India), and my family in another city have a 4 Mbps connection - it still pauses the video regularly when we talk - and eventually we switch to skype because it at least shows something, even if pixelated. I'm as disappointed by this 'feature' as excited I was before trying Duo.
His testing and analysis are not exactly rigorous. Even with an N=1 he comments about how he can smell the difference between the placebo and treatment.

In his most highly rated drug, modafinil, he took it on 8 different days and could tell which one it was 5/8 times.

8 days, couldn't tell the difference 3/8 times and it is his most highly recommended drug.

He definitely needs to try drug free, exercise and sleep over a month.
They're VC backed and plan a premium subscription sometime in the future. All of the current features will stay free. I think I've read it on their medium comment section or it's in the FAQ.

I read that as anonymous or prank SMS/MMS, not just any SMS/MMS.

CouchDB 2.0 is a direct descendant of CouchDB 1.x. The API is 99% compatible, same community working on it, you can replicate between them and so on.

I haven't used Couchbase, but I understand besides the "Couch" prefix and that CouchDB's original author working there for a few years, it doesn't have much in common with CouchDB project.
I would be surprised if it became popular.

Perhaps it doesn't have the features of Hangouts while it does have the requirement that you install another app and the stigma of it being a Google product (i.e. they collect all your info). Also lacks messaging capabilities.

It can only be used for very short 1 on 1 phone calls since I can't imagine video chatting for a long time from a phone. Also it can't be used with a desktop.

Otherwise, Skype and Hangouts are way better plus any decent WebRTC P2P chat like www.appear.in
And google is going to announce its new phones on 4th oct. If they are still 16gb then you have a point. With the new android update system where the phone has 2 system partitions and load the updated version on rebooting the phone means they will need more space anyway.
I've never even heard of it before! Sounds interesting!
From those gifs in the post, I assume it requires Google to scan every word I send. It will sense my tone to change the text style, and suggest how I should response. Well, why don't you just say it for me then? I'd love to see a bot representing me talks to my friends. And, a messaging app provides Incognito mode, lol, is there any other way to imply my conversation isn't private enough?
> It has fallback to SMS functionality, but SMS apps are rejected from the Apple App store.

Which guideline are you thinking of? My search for "SMS" only found two unrelated guidelines:

> 1.1.6 False information and features, including inaccurate device data or trick/joke functionality, such as fake location trackers. Stating that the app is “for entertainment purposes” won’t overcome this guideline. Apps that enable anonymous or prank phone calls or SMS/MMS messaging will be rejected.

> 3.2.2 (iv) Collecting funds within the app for charities and fundraisers. Apps that seek to raise money for such causes must be free on the App Store and may only collect funds outside of the app, such as via Safari or SMS.
