being a 2+ planet species wont help local overpopulation. it is too much more effective to ship a highly diverse sampling of frozen sperm and ova manufacture most of your people onsite. Moving that many people just does not make sense when you have more cost effective alternatives.

plus adding planets inside the solar system only gives you 2 real targets (mars and venus) mining asteroids to build spinning habitats is a much more viable colonization target.
These women are victims of harassment and abuse. It seems very unfair to expect them to also put their personal reputation on the line before we finally take them seriously. That's a very high bar to clear and it's the reason why so few women speak out publicly. That's why we must encourage, not discourage, anonymous disclosures, and give them the benefit of the doubt.
Ironically, all the effort to avoid regulation and oversight, will probably lead to far more expensive lawsuits on the flip side - Run a red light now, maybe hit a pedestrian later.
> Is burntsushi's Rust implementation of memchr notably slower than libc's?

Not as far as I know. A lot of this benchmarksgame code has evolved slowly over time and hasn't been cleaned up yet to use "modern" crates and language features.
I know how to read a map. I have a good memory. I have a good sense of direction. I did a fair amount of driving before getting a smartphone/GPS. I delivered pizzas for ~3 years, and I'd look up the 1-5 houses on our paper maps at the store showing every street, nearly every house by number, most of the apartments by number, and then memorize the route. I drove cross country a couple times with basic AAA maps and printed Google Maps directions.

I'll defend using GPS on my phone to navigate. It provides a couple benefits that I really enjoy.

1. It knows what is ahead of me before I do. Specifically traffic, where it sometimes provides useful re-routing (although I dislike Waze's re-routing). Also, Waze's user reports can be helpful to warn about debris in the road, etc.

2. It has a consistent interface. When driving in an unfamiliar location, being able to look in one place to see if the next street is the one I need is way better than trying to find & read every street sign.

3. It has a voice interface, which I believe is safer than trying to read my handwritten notes or the printed google maps directions as a driver.

4. I appreciate seeing the current Speed Limit, displayed by Waze.

5. It greatly reduces the cost of missed turns. I hate seeing cars cut across multiple lanes of traffic (or even just one!) at the last minute to make their exit.

The GPS does make it easier to navigate. I think that frees up more of my attention to focus on other aspects of driving: watching the cars around me, looking for pedestrians, cyclists, and other hazards. I believe that actually increases my awareness of what's going on around me.

I agree that not everyone becomes a better driver when using GPS, but I think they could.
Google reports “high-severity” bug in Edge/IE, no patch available
Big problem is here is what is 'creepy'? We would literally need a standard or metric for this to make it enforceable. So many people are different and females have very different bars for what is acceptable for flirting from person to person.

Ontario started this years ago, but phased. So clustering of like ministries at first. It is far from perfect, but the trajectory has been positive.

> Dark matter is called matter because it has mass, i.e. it experiences gravitational attraction to itself and to other forms of matter.

> Dark energy is called energy because it acts like radiation, i.e. it has negative pressure.

I was going to post something similar, but tempered a little, since some participants in this discussion are skeptical of the existence of these things. I think the dark energy statement is fine, but would weaken the dark matter one to say, e.g., it's called matter because we can observe effects (lensing, rotation curves, etc.) which can be explained by the presence of matter.

In this way, dark matter and dark energy definitely exist, in the same way that centrifugal and coriolis forces definitely exist: they explain concrete observations, and by squinting at the formulae we see that the terms we've introduced have units of mass (dark matter), energy (dark energy) and force (centrifugal and centripetal).

The effects explained by centrifugal and coriolis forces can also be explained in a different way, by taking into account the rotation of our frame of reference. Articles like this one show that the jury's still out on whether the effects of dark matter and dark energy can be explained in a different way.

AFAIK dark matter is quite widely accepted as a fundamental explanation, rather than a "fictitious" one like centrifugal/coriolis forces, while it's common to treat dark energy as a "placeholder" at the moment: it may be a form of energy which permeates space, or it may be an effect of something else (e.g. some unexpected behaviour of spacetime, like discretisation or some other change of metric).

While we're still some way from understanding dark energy, I have no problem with models of dark matter (although SUSY's looking less likely every day); after all, why should we demand that all matter interact elecromagnetically?

On the other hand, when theorising about what dark energy might be, I think it's fine if that explanation encompasses the effects of dark matter too. Just because we discovered the dark matter effects first, it doesn't mean they must be explained first.
I don't disagree, but consider that many of these engineers are sitting on illiquid stock options valued at millions to tens of millions of dollars.

You're asking people to stand up for what's right when it may cost them millions of dollars of incentives and the loss of years of their life in career investment. That doesn't make it right to look the other way when these kind of abuses occur, but is it any wonder that people don't speak up when the incentives are lined up so strongly against doing so?
Another system from back in the days of pre-very accurate gps: The advanced snowplow program http://www.path.berkeley.edu/sites/default/files/documents/i... and from archive.org: http://web.archive.org/web/20070112182654/http://www.path.be...

Picture driving a snow plow in the California sierras in whiteout conditions. On one side of you is a steep cliff with no guard rails (not that guard rails would - the snow is higher than the rails).

So, they embedded magnets in the road that had data in them (the way they were organized):

> Two primary technologies are being used in the ASP: detecting the plow's position relative to the center of the lane, to assist the operator in steering; and detecting obstacles, for collision warning. PATH's magnetic marker guidance system provides guidance information. This system was developed for automated vehicle guidance and control applications. A single magnetometer array comprised of seven magnetic sensors was installed at the front of the snowplow. Signal processing of the magnetometers provides lateral position measurement relative to the center of the lane, longitudinal position relative to mileposts, and yaw angle estimate. Binary coding of the magnetic markers when installed (north pole up vs. south pole up) also provides information about roadway characteristics, e.g. the direction and radius of the curves. The obstacle detection system uses a commercially available Eaton-Vorad radar, incorporating a digital interface developed by AHMCT in conjunction with Eaton Vorad.
Uber's valuation is contingent on it becoming a monopoly or something close to it. That isn't going to happen w/o a pitbull CEO. Travis knows the business better than anyone else @ this point. A threshold of bad PR that is counter to said goal would have to be met, and I don't think this is it.
Even calling it a choice is rationalizing the loss of privacy. Most services are a binary choice of giving up privacy or not using the service. Some services can be done without, but many are required to operate in a modern society.
It's how science works, but it's not how politics and human psychology work. Trying to get a paper published that directly contradicts the established theories is almost impossible because people don't like their life's work being thrown away as incorrect.
This is why science advances one generation at a time.

Can you describe a general situation where this kind of skepticism is avoided? I'm keenly aware that selective application of standards of evidence in legal matters is a serious bias problem, but if you are suggesting it happens in some issue to people across the ideological spectrum on that issue I don't know what you're talking about.

FWIW I noticed many lower-level employees who did a lot of heavy lifting for the company had skill sets and productivity that may or may not have been correlated with ability to get linkedin recommendations or endorsements. I'd even heard talk of management refusing a recommendation because: "is he looking for another job? why is he asking me for that?"

If you look at the world through rational self-interest recommendations and linkedin profiles should be viewed sceptically.

Uber fired a top engineer for covering up allegations of sexual harassment
OK Cupid behaved poorly in that matter - after getting what they wanted (Eich resigning), they didn't act to resolve the reputational damage they'd done. All too quick to pop up a message saying "mozilla is the devil"[1], but afterwards, no message saying "okay, the situation has been resolved in our favour, you should go back and try it out". I lost a lot of respect towards the site from that.

[1] despite gay and lesbian developers coming out and saying that Eich's personal opinions on the issue didn't translate to company culture and they felt a positive atmosphere working there.
$40-$160M? I didn't realize just how far the price had fallen for a literal moonshot... Thanks!
But I mean, it's not about enjoying driving. It's about being an attentive and safe driver. One of the things my Driver's Ed class went over is that: Even if you are the victim of an accident, there's a decent chance that there is something you could have done to avoid it. Things like: Making sure you have 2 of your 4 directions clear, leaving extra space, and watching other drivers.

I think you're wrong that GPS reduce your cognitive load. It reduces it in the short term, but in the long term you are always listening to and referencing an noisey/bright device. In the long run it's a tax, and so it hurts your ability to be an overwhelming safe driver. This is an N=1, but I'm 30, and I'm a bit of a fast driver, and I've never been in an accident.
Years ago I rented movies at Blockbuster Video and one time as I was leaving the store with my rental a young man with a clipboard approached me to conduct a survey about the customer service. Part of the conversation went like this:

Him: Do you feel you had to wait a long time at the checkout counter?

Me: No, it was all right.

Him: How long did you think it took?

Me: About 3 minutes.

Him: Well, I happen to have been standing here with a stopwatch taking the time you were in line, and it turns out you were actually in line for 3 minutes. Now that you know how long it actually took, how do you feel about the wait?

Me: I, um, feel the same as before.
That happens to be one of the quotes in one of the related articles Medium suggests at the bottom that's worth the read: https://medium.com/@dhh/deleting-uber-is-the-least-you-can-d...

Just an aside, I think it's insane that women in tech are pressured (or feel pressured) to wear heels. Is this common in California?

Harassment isn't just making flirty comments or pursuing someone else, it could be discussing sexual themes at work, making derogatory comments about race, discussing other people's appearance.
Yes, nonprofits can charge money and hold onto it. What they can't do is distribute it to shareholders. Many universities are nonprofits, and they hold on to millions or billions of dollars. Nonprofits can also acquire companies, etc.
I'm an exception. Terrible sense of direction... My sister in law is an exception too. I swear she had a virtual map in her head that was always perfectly oriented.

I actually prefer having a GPS map north up, so that I can train my brain to have a non-relative mental map so that once I orient myself to the compass I can figure out where to go.

As it is, my mental map bears little resemblance to reality.

How many solar jobs will persist over time? Once the market is filled, there will still need to be maintenance and replacement when systems wear out. Seems like a pretty involved model to construct, but would be interesting nonetheless.

Broad assumptions:

IF all residential structures in the US had their own solar systems:

44 million residential structures [0]

4-person crew works 4 days to install = 16 man-days

250 work days per year

30 year useful life [1]

= 2.816 million full-time jobs

Naturally, not all residential structures will go solar. And, there are many solar-related jobs besides rooftop installers.

How will a migration to solar impact the current electric utility employment? Net gain or loss?

Honestly, the type that is afraid to be fired and doesn't want to rock the boat. I'd like to believe I'd stand up and say that's wrong, but never having been in the situation, I don't know how I'd react. I'd probably start navel-gazing, too. :(
Have you seen any literature on very low gravity rotary setups? Like <0.1g?

In the context of this thread, I'm mostly interested because it seems like a happy middle ground to solve your capillary action issues. However it would also be super interesting to see how a small acceleration like that could help with e.g. retinal problems from microgravity.

> Right. SpaceX doesn't have a craft capable of lunar orbit rendezvous

Why not? Their Dragon capsules can dock with the ISS; why wouldn't they be able to dock with each, possibly with some kind of adapter? You can imagine one Dragon and a trunk docking with another upper stage that's all fuel tank, heading to the Moon, undocking in orbit, landing, ascending, and rendezvousing in orbit to return home.

The total dv requirements of landing on the Moon and ascending again starting from low Moon orbit is 4 km/s. I haven't done the math, but I suspect that you can put together a workable mission using two Falcon Heavy launches. Now, granted, they don't have all the exact pieces put together quite yet, but I suspect they've been thinking about it.
Probably only until it became obvious that HR was suffering from the corporate equivalent of 995.81 (battered person syndrome) and will give a response of "Oh, he's a good person and has never done this before and I'm sure he'll never do it again, and if we rock the boat we'll be targeted as well."

Frankly I think Uber has long passed the point where I expect to start hearing about leaked recordings and cellphone videos of this kind of thing instead.
Abusing Google App Scripting Through Social Engineering
No. There is simply no excuse for this kind of abusive environment to exist at your company. If you are CEO, you are responsible:

- Kalanick doesn't interact with every employee every day like the olden days, but he certainly hired the people who do (directly or indirectly).

- Greenshift is a real problem, but it's not like the management chain is the only way a CEO can find out about problems.

And nobody's saying that Kalanick is telling his execs that it's OK to harass employees. In my mind, he is responsible and culpable even if he simply turns a blind eye when harassment happens.

"listen and believe"
The electromagnetic force (specifically, the Coulomb interaction) is 1/r^2. The strong force is actually effectively constant at long ranges, since it becomes energetically favorable to create an antiquark/quark pair. The residual strong force is exp(-r)/r. The weak nuclear force is exp(-r)/r^2 (or exp(-r)/r? I can't really tell with the links on hand--I just know for sure there's an exp(-r) term in it). Gravity being 1/r wouldn't be a surprise given the other known forces.
I agree with you in general, but it's important to keep in mind that border patrol and airport security are two almost completely unrelated things.

There is (almost) always stack ranking for the purposes of equity and bonus distributions, implicit or explicit. But there is also bottom xx% rule for people that must be given bad reviews and placed on PIP. In Microsoft 2000s it was mandatory rule to axe 10% of bottom performers within a team.
> Teams that don't fit a normal distribution are incredibly common.

> > Now, is it a valid criticism of stack ranking that it makes it not just difficult but impossible to describe a team that's solidly above average? Yes, absolutely. Stack ranking is kind of dumb.
First, it's not just about "get [them] in trouble". Think about ten years later. Do we want adversaries to have logs of children's conversations?

Also, It's not just recordings. Once an adversary has account access, they can talk to children. I can't imagine that being a good thing.
Show HN: A 'Marsarium' that simulates Martian soil and atmosphere
The key phrase in this statement is "for humanity", not "for an individual".

Automobiles, while useful, are mostly a solved technology (unless you're buying Tesla or some other prototype, pushing-the-envelope model). Buying another one - or for that matter, making another typical automobile - has negligible marginal impact on advancement of technology. Taking humans to the Moon again - first time in 45 years - will have a huge impact both on our technological capacity as a species[0] and on the public's willingness to pursue those advancements.

Also, spaceflight is an immature area of knowledge, so one could argue that in general, each dollar put in it has more marginal benefit than the same dollar put into buying typical consumer goods.

The problem is your workforce still wants a liquidity event that rewards them for helping build a multibillion dollar company. this means either company buy-backs or authorized secondary market transfers that will likely not result in the amount of money they expected.

Coal has already been losing to other sources, albeit not necessarily renewables. The cost of natural gas has plunged and getting coal out of the ground is more expensive than it used to be as we've already pulled out the easy to get coal.

A lot of the cost issues is about comparing wattage - solar has become way more efficient than it used to be. Coal efficiency has not changed much.

When? When they can't run me over and kill me. Uber is doing this to themselves - note other companies aren't having nearly as many of these issues, nor as serious, and deserve to be called out on it.

They have a history of lying and disdain for law. For months Uber told Boston police that they did do vehicle inspections, and when finally called out on it, the CEO admitted to the police chief that he lied. Recently they lied about running red lights...And they should be allowed to experiment on the roadway?

AWS Organizations – Policy-Based Management for Multiple Accounts
I'm really sad to see this news. When I was at Google working in Amit's organization, I thought Amit's department was a really good example of an organization that respected women, promoted women into positions of power, and just seemed like a very inclusive and supportive environment.

I was hoping that he would help clean up Uber, because Google search quality sure as hell did not work like any of these Uber horror stories that are coming out. Well that sure isn't going to happen now.

I don't know anything about whether these allegations are true or false but I am sad either way. If it's true then someone I looked up to is actually not such a great role model, and if it's not true then Uber is missing out on an executive who knows how things work in a better-run organization and could help them, and if I'm just wrong because I didn't see all the harassment that was going on in my workplace before then that's depressing too.

:-(
