So you're telling me you alter your biochemistry to become more productive without a care for how it affects your overall (mostly mental) health? Hell, I started smoking cigarettes at 16, which I rank near the top of my worst decisions ever, despite the fact that it helped me hack my brain chemistry as I powered through numerous difficult math and CS classes with top scores. As a result, I spent years thrashing, kicking the insane habit and returning to baseline healthiness.

To me, the entire idea of performance-enhancing chemicals is the essence of Moloch (http://slatestarcodex.com/2014/07/30/meditations-on-moloch/) - the supposed optimization that we choose to "gain an edge" and end up worse off than if everyone had just been a bit more cynical and abstained. To what ends? Eventually this kind of thing ends up costing you $50 a month and keeping you on par with everyone else in the office (who also happen to brain-chemistry-hack), side-effects be damned.

Luckily, I can fall back on my experience and relative skill at programming. Many cannot - as a late-aughts college student and "yuppie", I saw "the best minds of my generation destroyed by madness" induced by incessant Adderall use in a futile attempt to either "keep up" or "get ahead". To what ends? Some sped their way through upper-levels or toiled through back-breaking entry level jobs only to develop near psychosis, emotional numbness, apathy, and a resume piece that I too gained with considerably less strife.

Don't get me wrong, I drink a cup of coffee (or two) in the mornings to get going, but it's usually an break from my workday, not an essential part of it. More than that, it's enjoyable - added focus and clarity be damned. Silly as it may sound, I've even seen coffee become a problem for the hopelessly driven and chronically sleep-deprived - reducing them to diarrhea-ridden, jittery maniacs!

Maybe the TL;DR here is: sleep more, bike hard, and have some fun struggling instead of constantly grinding for carrots on sticks. It is true, after all, that many people (men, in particular) say their greatest regret was working so hard - https://www.theguardian.com/lifeandstyle/2012/feb/01/top-fiv...
Different people have different risk:reward ratios.

You've seen what gwern has written. He makes clear the monetary trade off. He also explains how some of the drugs are well studied, and most probably safe.

These people aren't crazy. You just don't understand...

Quick, let's ban everything except alcohol & cigerettes! They only kill a combined ~7.5 million people per year. Nice and sane.
> expect the OS to be faster, more stable, crash less, and have more actually useful features, both for developers and casual users

Haha... that is such a wishful thinking these days... Jobs nearly made me feel that's actually possible, but lately, it became a dream again.

iOS is where all the cash is but for people who both use iOS and macOS, both are equally important but Apple is no longer good at keeping mind shares.

Perhaps what Apple did in the last 5 years could've been done in a few years with Jobs with "a few more things" .
(people need to upvote parent). You started from the lowest-level (reading word by word) but I started at the highest: after skimming the first couple of sentences I scrolled down trying to get an "overview", I tried to take in the main things, to read a Conclusions section, to read something that would put all these things in perspective. (The "background" first section and the couple of sentences that precede it aren't any kind of good abstract, or if they are then I missed it while skimming.)

But I didn't see it - I couldn't "see the forest for the trees."

So take it as strike two against the author and therefore against nootropics: while there might be a wealth of detail that it uncovers, too many details will make you lose the perspective, and, indeed, the whole point.

Like when someone writes a groundbreaking optimizing compiler or something, but can't even tell you why.
Very cool. One variation I'd like to see in the same algorithm is without the padding or borders, just the gradient-ed quadrants.
Says it's available for iOS. Not available for iOS.
All we need now is a proof that the proof program is correct. And a proof that the proof proving program is correct.
It's more complete than Bootstrap? I haven't done any research but I'm sceptical as there are so many Bootstrap-compatible plugins.
Facebook did provide XMPP service until the same time that Google ended it.

So that’s definitely a wrong statement.
They seem to buy a lot of useless stuff though.
You must live in a bubble or have never worked at a large company before. There are two totally different teams building these products. Is it really that inconceivable for them (yes, even Google) to make this oversight?
People that don't know math just reinvent it poorly. A lot of people use databases, and their SQL query with joins is performing set operations and they have no idea it's math. If You gave them the same dataset in an array, they wouldn't use a Set collection to solve it, but would loop over the dataset multiple times plucking what they need.
Thanks for your insightful reply, quant isometry sounds like a great counterexample, will read up on it
At my previous job ( https://www.rsa.com/ ), where I worked for 7 years, I've often had to use various mathematical techniques to do my work as a software engineer.

Here are some concrete examples from my career.

* Combinatorics and probability theory - Entropy analysis of authentication schemes, algorithms for enumeration and analysis of related combinations and permutations, etc.

* Calculus and probability theory - Implementation of bloom filter for space-efficient indexing, tests and analysis of false-positive rates, etc.

* Statistics - Adaptive authentication schemes, performance measurements and predictions, network event correlation, etc.

* Discrete mathematics and algorithms - Tree traversals, graph search algorithms, etc. were useful in a variety of situations, e.g. data retrieval in tree-based distributed databases.

* Asymptotic analysis, Big O notation, etc. - Data deduplication in distributed databases.

* Modular arithmetic - I didn't really implement any cryptography algorithms; I only used them. But the understanding of modular arithmetic was essential to understanding some of the limitations of cryptographic algorithms based on modular arithmetic, e.g. why the message size cannot exceed the size of the modulus, as well as for software engineering tasks like decoding certificates found in network traffic.

* Formal language theory, DFAs, etc. - Parser generators for network event parsing, SQL engine development and related query optimizations, etc.

So these are 7 examples from 7 years. There may be more examples but I cannot remember them right now.

I have felt from my personal experience that although most of the work does not involve mathematics, once in a while an interesting problem comes up that can be solved efficiently with the knowledge of mathematics. It is not easy to predict when such a problem would come and it is not always easy to recognize whether the problem at hand can be solved or analyzed efficiently by known mathematical techniques. So it is good to have someone in the team or be the person who has a good breadth of knowledge in mathematics, so that when such problems do come up, they are addressed efficiently. Fortunately for me, I love mathematics and there were people around me who also loved mathematics, so we got a lot of interesting work done.

"It's hard for me to fall asleep. I haven't cracked it yet how to do it perfectly. What helps: view the problem as improving your likelihood to sleep. Before I viewed the problem as falling asleep 100% of the time, which is a really defeating view to have when I can't fall asleep."

I did not respond to your sibling comment who speaks of anxiety. It sounds like a real pathology and something I have no business generalizing about.

You, however, mention no such thing so I am emboldened to encourage you to exercise - something not mentioned in your list.

I would experiment with both walking for 2-3 hours (on a day off, presumably) and also a 1.5 to 2 hour intense weightlifting workout (primarily focused on your thighs/legs[1][2], since they are the biggest muscles.

I'm not saying to do these things on the same day, just that they are both good candidates for an exercise activity which could influence your ability to go to sleep.

I like your list - especially getting out in the sun early and setting your circadian rhythms, but your list strikes me as it would somebody putting special air filters in their car when they've never taken it in for an oil change. Only reach for the specialized optimizations when you've exhausted the major factors.

[1] which implies squats and deadlifts, although a real leg press (the kind you load with plates, not select weight from the stack) would also do the trick.
After reading your suggestion, I just donated $200--it was $100 but I stepped in for koolba

and iOS provides an official API for adblocking since version 9.

IMHO adblocking is even more relevant on mobile because of latency & data caps.
I feel like incognito mode has been around long enough that this isnt a valid excuse.
What's the uplink speed on the other end (presumably 4Mbps is downlink)? That would be a more limiting factor in the quality of the video you see on your end.

But then I recall we had working video chat a decade ago with only a few hundred Kbps...

The problem is you are taking her word for it. I think she's a liar, and her actions just reinforce that.

I do NOT demand she hand over personal email! No. Only that she make it possible for a 3rd party to sort her emails into private/public.

She has the right to delete personal email - but only if it's actually personal, and I don't trust her to be the one to decide that.

She brought this on herself by mixing them in the first place. Want to maintain your privacy when you know you job requires publicity? Keep your public and private lives separate. She chose not to.
I tried melatonin and this was my experience. It also started giving me a headache if I forgot to take it or ran out, which is annoying.
Exactly. The listed stimulants will solve a short-term need. But people here are looking for a long-term permanent solution that can be used every day.
Google just keeps pushing boundaries trying to legitimise spying. This is really creepy, and its surprising that Google and folks who work there think its ok to do this. Might as well have an NSA drone tail you.

It's as if Google's ad business is just a front for a global intelligence gathering operation.

There is a real problem with Google here and a golden opportunity for less privacy invading businesses to take its place. I am sure as users becoming more aware they will increasingly gravitate to businesses that can operate less creepily.
I think it's being treated as noteworthy due to reaching a milestone. It doesn't feel very long ago that we hit 1GB.

I have always been interested in this area of programming. One thing I have always wanted is the ability to enforce restrictions on data types beyond memory. By that I mean say i am using an int, what if I want to restrict this to actually 1 -55 you can solve this using run time error handling but wouldnt it be better if we had static checks where upstream we could see an unbounded int being passed into this method and throw a compile error.
I was referring to the need for a martyr. Though if you are biblically minded, then by allowing Snowden to be crucified we are bringing a curse upon ourselves, cf Barabbas.
Breast Care Capsule
Agreed. "Copy Password to Clipboard", anyone?
The thought of having that being transmitted unencrypted to a cloud server is not a nice one...
Important to note that the maths used in AOCP is briefly covered at the start of Vol I. This was expanded upon in the form of Concrete Mathematics.

If you want just the maths and at a slightly slower pace, go with Concrete Mathematics. If that's a struggle, I found the first part of Discrete Mathematics and its applications by Kenneth Rosen was enough for me to make progress in Concrete Mathematics.

I also found learning a bit of linear algebra and calculus was a mind changer. I expect more fruits by my continuing of those studies.
> I still don't see what that has to do with Communism

> my point is its the incompetence and authoritarianism that caused the problems

A lot of people believe there's a causal road from Communist governing philosophies to incompetent authoritarianism (though you're right, it certainly wouldn't be the only way to get there).
This brings back my memories (maybe 12 years ago) developing the 1GB CompactFlash card firmware at a previous job. That amount of capacity felt unbelievably huge at that time. Infact the first cards I worked on had only 4MB capacity!
Good to see v2.0 took them quite long but hey better late then never.

I don't think it's acceptable, but at least "collateral damage" has the virtue of having been approved by elected officials and is something considered before we go to war or order attacks somewhere. Snowden's leaks weren't approved of by anyone but Snowden, and if they had managed to get people killed even if that wasn't Snowden's intention they would still be enough to consider as Treason.

In counter point, if we start allowing anyone who feels like they can leak this stuff on their own authority, and it starts costing lives of Americans, how many would you consider "worth it"? At what point does it move from whistle-blowing so it's okay to treason?
> Google shut down XMPP support because none of the other large vendors were playing along.

That's a lame excuse that Eric Schmidt produced for abandoning XMPP. The irony is, he should be blamed for the same thing he blamed others for.
But perhaps middle out compression?
Middle-out encryption ...? :)
I found it kind of funny that the author's big conclusion was less state-directed action, leaning on the thought that somehow the economy will work out for everyone as long as we get out of its way well enough. A type of magical thinking.

Unfortunately economics is split between an evidence-based field that occasionally changes its mind when its wrong, and a proliferation of "schools" and "think-tanks" that provide a selection of justifications to do what you already wanted to do. The science of how governments should handle money is too important not to be made into a political football.
So let me get this straight, it works with older XMPP servers, but not modern, up to date versions of said servers?
I'm aware of two primary reasons to oppose the plebiscite, neither of which aligns with your thesis:

Supports of gay marriage oppose it because it's a foregone conclusion (most polls find a solid majority in favor of gay marriage), a hugely expensive exercise and non-binding to boot.

Opponents of gay marriage oppose it because having rock solid data about the level of support would make "but won't somebody please think of the children!" type fearmongering harder.

TBH, I'm not really sure why anybody even in government supports it, but that's Aussie politics for you.
Not quite:

- Facebook Messenger combines all the functionality of Allo and Duo.
- Whatsapp already has voice calling and is adding video soon (so I read on the internet)
- iMessage and Facetime integrate in IOS much better than Google Duo does. In IOS, you go to a contact and press facetime. On Android, you go to a contact... then go back out to Duo and call them.

WeChat, of course, does everything that all these apps will ever do - as of many years ago.
Yeiks. I wonder how many will be burned by that...

Just tried it in Chromium, see a "quit Smoking" ad. Nothing in FF.
I'm guessing part of the negative reaction you're getting is because great people don't just "get SV salaries" no matter what. To get an SV salary, you need to find employment at a company able and willing to pay an SV salary. Being a great engineer does help a lot, but you need to chase the salary, it won't just fall into your lap.

It's much harder if you want to be remote, and very hard if you want to live in a country where no company pays SV salaries.

Yes, but with planes and ships (on ships it's almost always called track pilot and speed pilot, by the way) you can let go of the controls for extended periods of time. In cars, right now, that's a recipe for disaster. Functionally they may be the same, but practically speaking it's very different.
Google is treating video calling as it's own seperate thing.

I much prefer Facebook Messenger where its about the contact, and u call/msg/video them and its all there in one stream.

Google's disjointed approach to messaging/calling doesn't make sense to me or my non-techie friends.
I would like to see a case of a cold boot attack by the police.

I know, but nobody else will ever know because Google keeps losing all of its users to itself. Everybody I know got frustrated and moved on to things that just work... like ancient SMS, FaceTime, Facebook, etc. If you say "google" anything to them they just say; too complicated, doesn't work, UX sucks, etc. I think in reference to the UX people are speaking to chrome plugins.
Thanks for posting PEPPER, @neuling!

We’ve built PEPPER with the goal of making it easier for visitors to get in contact with a website’s owner – through various social medial channels, phone, email etc., without the need to CTRL-F to find that hidden ‘contact’ link in the footer.

Thanks for giving PEPPER a try, we’re very much looking forward to your feedback!
Carved in Stone: Immutables in JavaScript
but hangouts lacks things which are useful for enterprises such as video recording (it's possible only if you make a "hangout on air", afaiu) and, in my experience, screen sharing text/code is painful because of the video encoding making it unreadable.

To me hangouts looks like a competitor to Skype only, at this time.
Cronicante13: La muerte no siempre es el final
I'm having the same issue with Duo. it pauses the video frequently. I switched back to FB Messenger, which just works without pausing video.

Google had said something about Google Duo being bandwidth friendly and good for slow connections but FB Messenger is miles ahead, at least in my usage. Which left me quite disappointed with Duo, as I like the idea of using Duo over FB.
First I would recommend Cal Newport's blog about using time wisely. http://calnewport.com/blog/2008/11/25/case-study-how-i-got-t...
Plenty more great info in the archive: http://calnewport.com/blog/archive/ Obviously the best way would be to go through your school's course syllabus for whatever classes you want to take and look at the material you will be doing, but these are good for a general preparedness:

Axler - Precalculus 2nd version
http://precalculus.axler.net/
He works through every odd exercise solution, in full. Also gives you a good intro to sets and series, summation notation, binomial theorem, all this will come up later in discrete math. He assumes the reader knows nothing about Trig as well.

Gilbert Strang's videos "Highlights of Calculus"
https://ocw.mit.edu/resources/res-18-005-highlights-of-calcu... just to get an overview of what calculus really is since I assume your university will throw you into an applied single variable class first year. MIT Open Courseware has their calculus (18.01/18.02) course lectures up if you want to watch them too to get an idea of what you'll run into.

"Elements of Mathematics: From Euclid to Gödel" gives quite a good explanation of Mathematics as a whole, like why we learn elementary math the way we do and how it applies to more advanced concepts, explains Rings/Fields and has a really good introduction to Logic. I wish this book existed 5 years ago when I started http://press.princeton.edu/titles/10697.html

"An Introduction to Mathematical Reasoning" by Eccles is short and excellent. You can also download the lecture notes here from CMU's course on proofs http://math.cmu.edu/~svasey/concepts-summer-1-2014/ and try some of the homework if you want but you probably won't see any of this until second year judging by most university calendars and recommended program course list I've seen.

CLRS https://en.wikipedia.org/wiki/Introduction_to_Algorithms which has a great first chapter "Foundations" that compliments Knuth's 'Mathematical Preliminaries' chapter in TAOCP vol 1. Knuth's book you can really drill yourself in these concepts though with the many, many exercises writing proofs. The skills I learned doing these exercises paid in full years later when I started more advanced math and even at work.

I've observed in the past that storage capacity per drive/media seems to grow at around roughly three magnitudes per decade. I'm looking forward to my 1PB SD card equivalent in the late 2020's.
The technology behind the feature is great, don't get me wrong. But there's something so empty about the Labrador response.

I want a discussion with a human. Not a human-curated conversation of algorithm-determined responses.

Simple human conversation isn't as much of a problem-to-be-solved as they seem to think it is.
Germany Again
The first two and the last are Indo-European languages; it appears that mother in Chinese is "mu".

It's "obaasaan" in Japanese, though. It'd become "baa" if you remove the polite syllables, and thus also ends up becoming a labial consonant (ओष्ट्य for those familiar with the verse in पाणिनी).

Curious indeed.
Sort of a tangent but I agree in the character generation from working. I had it too, and I appreciate having had it. I wonder if this really is part of the reason for later launches for millenials.
>> I got downvoted into oblivion.

Sometimes it's not what you say but how you say it.

If I say that "I believe there is an invisible world all around us" that's sort of the same as saying that most of the mass of the universe doesn't relfect light and so cannot be seen, as in Dark Matter- except a) I'm not a physicist and b) I haven't got a clue.

Or, say, you can get to the right figure with the wrong calculations. Say, 5 + 5 = 8 / 2 = 4 * 3 = 10. Whut?

So maybe you had the right idea but couldn't explain why it was the right idea and people downvoted you? Because if you can't explain why something that sounds far fetched isn't, people will tend to think you're talking nonsense. And rightly so, and so should they, as should you too.
Assuming Let's Encrypt knows more about its sustainability than you do, and given that they can also invest their money in index funds if they believe it's the right approach, isn't giving the money to them outright just better?
