The dash cam video was only released last week, in conjunction with a lawsuit. Now it's on all the mainstream news outlets, from the Wall Street Journal to the New York Times to Fox News.

This is yet another "Tesla hit slow/stopped vehicle on left of expressway" accident. There are now three of those known, two with video, one fatal. Watch the video. The vehicle is tracking the lane very accurately. Either the driver is very attentive or the lane following system has control. Then, with no slowdown whatsoever, the vehicle plows into a stopped or slow-moving street sweeper.

Here's one of the other crashes in that situation.[1] This was slower, so it wasn't lethal. There's another one where a Tesla on autopilot sideswiped a vehicle stopped at the left side of an expressway.

I think you already know that practically, it is pretty much impossible that you will close the gap at your current company. The fact that such a large gap has persisted over multiple years demonstrates that your management doesn't reward performance in a competent manner.

If you land a position at a Big 4/5, you can expect to make 300k+ (total comp), and still retain flexible work hours, PTO, etc. Competition for dev talent is fierce, and with good interview / negotiation skills, it is possible to make integer multiples of your current comp without sacrificing perks such as a good team and flexible hours.

That's unlikely. The LATimes tracking poll is known to be unorthodox in its methodology, it's meant to track fluctuations in support more than actual support. Trump has not broken ~6% in any other swing state polls or national polls that I've seen, sometimes he's in 4th place behind Johnson and Stein.

As it turns out, delegitimizing and spreading conspiracy theories about a wildly popular president in a community does not make people in a community fans of you.

Reddit actually has an active nootropics community with a wiki for beginners: https://www.reddit.com/r/nootropics/wiki/beginners.

The standard stuff is L-Theanine + Caffeine. For cognitive enhancement any of the "racetams" are considered proven, and you branch out into untested army drugs when you take modafinil.

I've tried each of these and stick with L-Theanine and Caffeine daily. Piracetam had no visible effect on me. Modafinil got me through 36 to 50 hour work days straight, at crunch time when deadlines were needed for an old job. Work was probably at about 60% of its best at the time – easy to get into the zone but also not quite my best. I know it's not healthy but I was also curious and happy to try it out of personal curiosity. YMMV :)

I would think though that in most cases, the persons considering a Mac are rarely looking at the specs to make the decision - Apple hasn't tried to compete with specs for a long time, and instead relied on word of mouth and OS X to carry them. Maybe a refresh would help make that a bit better, but I also feel they're stuck in a bad loop where because of how long it has been since a refresh for some devices, they need to really release something crazy good for the price to avoid the ire of purchasers.

It's no more dense or abstruse than the introductory philosophy text I've started reading. Yeah, it might take you a try or two to understand what they're saying, but that in and of itself isn't a very strong case against the article.

In fact, the writer actually agrees with you, in a sense, in that second sentence. He mentions that the piece is strictly anecdotal and should be taken with a grain of salt, and that you shouldn't burn too much time on this stuff because there are limits to what you can achieve.

Maybe you should give the article another go. You might learn something new, or at least have wasted your time in an engaging way.

Melatonin has worked wonders for me as well. However it's worth mentioning that the 3mg capsules I bought are WAAAY too strong and cause me to wake up with a dry mouth and a headache after a couple of hours of intense dreaming and nightmares. Instead now I split the caps open and take a tiny fraction of the melatonin every night. It takes me a few weeks to go through a single capsule.

I have a similar printer.

The word "giclee" does not even appear in the description, but "inkjet" does. It's still an ordinary injet printer. It's bigger and more accurate than most. I've never seen them put in rooms so small that they'd "fill the room", I've usually seen them in rooms with several printers.
You should switch to valerian root if you can. It isn't habit forming in the way that melatonin is.

edit: since everybody is asking the same question about habit forming. I am just passing on the information that I got from my doctor. She made this suggestion to me, and it was beneficial to me. Once I had started using melatonin, I would have trouble falling asleep without it. Valarian root didn't cause that issue for me.

Its concerning to see Modafinil on the same list of "defaults" as caffeine and vitamin D. They are on a different scale when it comes to the effect on your brain.

That aside, my anecdotal experience of mod is its basically a waste of time. Sure you stay awake longer but we can all easily procrastinate a day away regardless, it wont make you any more focused or any smarter. If you for some reason need to improve your focus for a period then dexamphetamines are the way to go, of course you should not pop them every day.

> you branch out into untested army drugs when you take modafinil.

What on earth are you talking about? Modafinil is very much _not_ an "untested army drug". It's pretty well-studied, approved for use by the FDA, and available for sale (with prescription) under multiple names in the US, and by prescription with no other legal restrictions in most other countries. It has a freaking WebMD page[1]!

Ask HN: How to solve chicken and egg problem?
I created an app during my spare time and although it's a great idea and people have praised it, I am having a hard time getting over the chicken and egg problem.

What is it and why I made it?

It's an app to buy and sell stuff at your workplace. It's different from local sell since you only see stuff which s posted by people who work in the same building as you. I believe it's safer than local sell since you don't have to interact with strangers. I know a lot of people post flyers in their office's break rooms to try to sell stuff and I thought it will be great to make an app for this purpose.

My problem:
I am getting a lot of random users from different cities but having a hard time getting multiple users from the same building. The app can only be successful if multiple users in the same office download this app and post items. If it's just one user then there will be no one to buy their stuff. The purpose of the app is to buy/sell with your co-workers, therefore I can't post items at other offices.
How can I get over this problem?

My apps:

https://itunes.apple.com/us/app/breakroom-buy-sell-stuff-at/id1143880147?ls=1&mt=8

Or..... they could just get rid of the bloat. I'm sorry that so many sites suck at building web-pages, but that's not really my problem. I have no problem un-blocking sites that are respectful, and I often do, but pretending like this is a good thing for users is just silly.

More specifically, going up a fifth augments the fourth by a semitone to become the seventh and going down a fifth diminishes the seventh by a semitone to become the fourth. In your example, F the fourth became F# the seventh and B the seventh became Bb the fourth. A fifth away _IS_ a semitone away.

Defining the following eight functions:

SEMITONE = +1 mod 12; ANTI_SEMITONE = SEVENTH;
FOURTH = +5 mod 12; ANTI_FOURTH = FIFTH;
FIFTH = +7 mod 12; ANTI_FIFTH = FOURTH;
SEVENTH = +11 mod 12; ANTI_SEVENTH = SEMITONE;

We ask ourselves why the following holds:

FOURTH(X) = ANTI_SEMITONE(SEVENTH(FIFTH(X)))
SEVENTH(X) = SEMITONE(FOURTH(ANTI_FIFTH(X)))

Substituting, the answer is clear:

X + 5 = X + 7 + 11 - 1
X + 11 = X - 7 + 5 + 1

Keys one fifth apart differ by one note because:

1 = 11 + 7 - 5 mod 12

Algebraically it seems to work out...
It breaks down like any material. The easiest way to sample this would be the REALLY cheap cd-r discs you could get in the late 90s. If you left one of those sitting on your dash, they would borderline melt in the sun... and for sure start peeling off the plastic if they sat on your dash for a couple hours.

MLC lasts long enough and it is significantly cheaper. That's very logical.
Math is rarely necessary for software development. However, math is one way great engineers distinguish themselves from okay engineers.

I work primarily on audio software. Linear algebra is most important, followed closely by signal processing. Those are sufficient to write good software. Great software requires statistics, calculus (mostly for optimization but also modeling), and discrete math (again mostly for optimization). Other specialties probably require more discrete math and less linear algebra and signal processing.
The fonts make it nearly unreadable, but it's a good article, well worth reading through. Two thoughts:

My hope for the alt-priest replacement is Steve Keen, who seems like the only guy with a reasonable explanation why orthodox economics is so consistently useless, and a concrete policy suggestion (modern debt jubilee).

Which gets to my second thought: the current problem is not productivity growth and, in any event, productivity growth is a shibboleth (just pouring more gasoline in the engine and belching more exhaust into the sky produces more useless plastic tchotchkes, for God's sake). The current problem is debt. A very specific debt. It is the debt slavery being forced on our young people in the form of education debt and housing debt. It is crushing family formation, particularly among the most educated.

No children, no future. Not with a bang but a whimper.
In regards to modafinil, it is a schedule IV drug in the US. It's a bit difficult to get and quite expensive. I've done well with adrafinil, which is a prodrug of moda and relatively easy to get.

Autonomous vehicles don't really reduce the number of cars on the road, though. They just reduce the number of parked cars. You need great public transit and great walkability to really reduce the number of cars.

Pretty impressive work. I personally use nicotine gum (as does President Obama, a health nut) as I'm allergic to caffeine. I have used melatonin in the past, though given this I will use it more now.

The key I find is to only use them when you have already outlined in a detailed way a significant set of tasks that need to be performed or a particularly critical meeting where you already have a very strong background.

For learning, general creative process I don't use them.

The biggest problem is managing the physical addiction (ie, you feel very tired) when you're not taking them.

Also there is some evidence that nicotine increases incidence of cancer. Not to mention what it does to my blood pressure, though I find constant exercise helps manage that.
I totally thought it was untested back when I did it, though that was 6 years ago. And one of the few things I read about it in terms of studies was its effects on army pilots during 12+ hour training sessions here: http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA533725, hence why I thought it was an army drug.

So...after two years on a low calorie diet and exercising, one group using a tracker and one group not:

> Those who had not worn activity monitors were, on average, about 13 pounds lighter now than two years ago.

> Those who had worn the monitors, however, weighed only about 8 pounds less than at the start.

13 calories lost in two years is a calorie deficit of about 60 calories per day. 8 pounds in two years is a deficit of about 40 calories per day.

I don't think that a diet with such a small calorie deficit should really count as "low calorie". That's ordering your Whopper without cheese. That's using "I Can't Believe It's Not Butter" instead of real butter on your pancakes. That's getting light mayo instead of regular mayo on your sandwich.

If the two groups ate about the same, so that the difference was entirely due to exercise, then the first group did about 20 calories extra worth of exercise a day. That's about 5 minutes of walking. That's brushing your teeth after every meal instead of just once a day. That's reading for a half hour.

I think it is interesting that the group using the fitness tracker exercised slightly less, but the effect seems small enough that I doubt it has any practical implications for most people who are trying to lose weight or keep lost weight off.
They're going to tax the productive autonomous systems (whatever you want to call them, robots, AI, etc).

The politicians are not going to have a solution as fast as the job losses mount. They're going to want to force-fit the solution into their existing way of thinking, into existing frameworks, what they've always known politically and that means taxation + redistribution through existing channels.

If you replace a fastfood worker with a robot, as an owner you're going to pay a fee or tax for that. Politicians will justify it by saying it will go to unemployment benefits or similar.

They're also going to pass laws restricting productivity gains by robots and AI. A fastfood worker can't work 24 hours per day but a robot can. Laws will start to be passed in the near future, stipulating that if you want to use autonomous systems to replace human labor, then your autonomous system can only function near the capability of a person in terms of hours worked or total output potential.

It'll be called the Fairness in Autonomous Labor Act (of 2032).
