JamilD··on "Payload to Mars" Added to SpaceX Pricelist
You would have a hard time finding a court to enforce your claim too, since the Outer Space Treaty states:

Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.

JamilD··on "Payload to Mars" Added to SpaceX Pricelist
I don't think it's illegal, but it is enforced by COSPAR's recommendations on Planetary Protection. Missions to Mars actually have a much higher threshold for avoiding contamination than, say, missions to the moon. https://en.wikipedia.org/wiki/Planetary_protection
JamilD··on CV of Failures [pdf]
I was just thinking the same thing. It's so easy to look at someone else's public, social media persona and forget about the struggles that they've faced as well. There's immense pressure to show a face of complete perfection, even if that's not the reality.

I can imagine it being incredibly freeing to drop that pretense, both for others and oneself.

From the police scanner audio [0]:

"Information for our units [inaudible] at Apple Campus, Infinite Loop, for a 10-56 attempt... female employee bleeding from a head wound to the head, possibly has a gun. Looks like security was escorting the employee down, and the West Side units is now arriving. And I do have further [inaudible] that they are advising there’s a body in one of the conference rooms with a gun so we’re not sure if there are multiple people involved."

10-56 is the police scanner code for a suicide. The audio refers to a "female employee" when the police confirmed the victim was a male, so I'm not sure of its veracity.

JamilD··on The invisible language of trains, boats, and planes
You can see crowdsourced ADS-B data at https://www.flightradar24.com; it's a pretty cool visualization, and far more accurate than other flight trackers.
JamilD··on Don’t Blame Silicon Valley for Theranos
I agree with you completely, but is it really Silicon Valley's place to decide which regulations to abide by, and which to ignore?
JamilD··on iPhone Sales Drop, and Apple’s 13-Year Surge Ebbs
The expectation was $2.00 EPS, Apple reported $1.90. AAPL is down in after-hours trading right now, at 95.91 from 104.35 at market close (as of 5:20 PM).

This is a significant earnings report as it's the first to break 13 years of continuous growth. Revenue was down 13%.

• Q2 EPS: $1.90, down 22% YoY, versus expectations of $1.99

• Q2 revenue: $50.6 billion, down 13% YoY, versus expectations of $52 billion

• Gross margin: 39.4% versus 40.8% last year and expectations of 39.47%

• iPhone unit sales: 51.2 million, down 17% YoY, versus expectations of 50.7 million

• iPhone ASP: $644.25, down 2% YoY, versus $651 expected

• iPad unit sales: 10.2 million, down 19% YoY, versus expectations of 9.4 million

• Mac unit sales: 4.03 million, down 11% YoY, versus expectations of 4.6 million

• Q3 revenue guidance: $41 billion and $43 billion, versus expectations of $47.35 billion

JamilD··on San Francisco Torn as Some See “Street Behavior” Worsen
One of the metrics, as mentioned in the article, is the probability of a child being in the upper quintile of income, given that their parents were in the bottom quintile (hardly wining and dining with VCs).

In SF, that probability is 0.122, or 12.2%… extremely high relative to the rest of the country. Atlanta is 0.045, and even New York City is only 0.105.

> But the way to stop people stealing to survive is to help them find some more productive way to survive.

I agree with this completely – ultimately, you have to find a better and more sustainable solution.

But right now, some people know they can commit crime in San Francisco, and see it through with relatively few consequences, causing a concentration of crime in the city. It provides an incentive to crime… and ultimately, ignoring it won't make it go away either.

JamilD··on San Francisco Torn as Some See “Street Behavior” Worsen
I agree San Francisco has its problems, but calling it a failed city is grossly overstating the problem. San Francisco continues to have a high degree of social mobility relative to the rest of the United States [0].

JamilD··on San Francisco Torn as Some See “Street Behavior” Worsen
In San Francisco, if you leave anything worth more than a couple hundred dollars in your car, it's as good as gone.

It took me a while to get used to the level of crime in SF too… it's so different from even North San Jose or Mountain View.

> “We are not going to criminalize people for being poor,” he said. “That criminalization is only going to make it harder for them to get out of poverty.”

No, but we should criminalize people if they commit crimes. Laws exist for a reason, and they must be enforced to be effective.

JamilD··on The Science of Making Friends
I found that going to talks and events to meet people can be extremely effective. I love living near a university, for example, to go to public colloquia and talks — you meet the most interesting people there, who often share the same interests as you. Going to a Papers We Love talk [0] can be a great opportunity as well.

Of course, this is really only available to people who live in a large metropolis, particularily if you live in the Bay Area (if you're interested in science and technology in particular).

JamilD··on Opera VPN behind the curtains is just a proxy
I can understand this argument.

The term "proxy" immediately brings me back to the days of trying to bypass the high school content filters using sketchy foreign proxies…

JamilD··on Bots won't replace apps, only better apps will replace apps
The last part of this reminded me of my favorite part of BB10, when I briefly used it: BlackBerry Hub.

It was so freeing to have my texts, Facebook messages, emails, etc in one place. People noticed I responded to messages faster, and I was much more organized than when everything was fragmented into different apps. I just need something like this on the OS-level on iOS.

JamilD··on Ex-Reddit exec launches 'Imzy,' a warmer, fuzzier Reddit
I think that the point of the downvote button on HN is to reduce the visibility of comments that don't contribute to the discourse, not to dismiss dissenting opinions.

This is helped by the fact that it's used sparingly and is only available to people with a certain karma threshold (an imperfect metric, but one that's worked reasonably well so far)

JamilD··on Nazi Propaganda: Out of the Cage
And who gets to define who has ideas that are unacceptable anyway? Who gets to accuse ideology x of "repackaging and resubmitting ideas"? Whose speech do we shut down, and whose do we allow?

> And you think debates are healthy, yet they wouldn't give you that privilege if they were in power.

So we deny them the privilege of debate, because we're afraid that if they get into power, they'll deny us the privilege of debate?

JamilD··on Nazi Propaganda: Out of the Cage
Exactly; is our ideology so fragile that we can't tolerate or allow dissenting speech?
JamilD··on The Heart of Deterrence (2012)
What is the moral distinction between one of their innocent people and one of our innocent people?
JamilD··on The Heart of Deterrence (2012)
> The President must distinguish "them" or "us", otherwise he has no business leading the country in a war.

Starting from the 60's, the concept of MAD and a truly global, total war made this distinction irrelevant. As soon as you push that button, you're not only condemning "them" to death.

JamilD··on Functors, Applicatives, and Monads in Plain English
I don't think the issue is with the simplification itself, but with the illusion of complete understanding.

There's nothing wrong with making a concept easier to digest, and to introduce a topic to an otherwise uninformed reader, but you have to do so with the clear disclosure that there is always more to it.

Everybody starts somewhere when learning.

JamilD··on A Marriage Gone Bad: Walgreens Struggles to Shake Off Theranos
It's truly a shame that cronyism is becoming a larger part of the technology industry.

Let's hope Theranos acts as a warning to VCs, and not as an indication of things to come…

JamilD··on I Don't Want to Hire You If You Can't Reverse a Binary Tree
That's missing the point of the article.

The author says that the candidate's thought process behind arriving at the solution provides insight into the candidate's skill.

There's no reason to implement your own binary tree, but knowing how to devise algorithms to accomplish a given task is a necessary competency.

JamilD··on A Marriage Gone Bad: Walgreens Struggles to Shake Off Theranos
And don't forget to drop out after a year of college! You've made all the connections, so what else is there to learn?

There are some exceptions to this pattern though, like Jan Koum and Andy Grove. We desperately need more of them in today's tech environment.

JamilD··on A Marriage Gone Bad: Walgreens Struggles to Shake Off Theranos
A role model for young women with parents coming from old money, with both Beltway and VC connections?

It'll be great to have another role model in tech for young women, but incidents like this do more harm than good…

JamilD··on I Am Alex St. John’s Daughter, and He Is Wrong About Women in Tech
The tone of it was more like: love your job for whatever hours you are there, even if it's 80 hours a week, and if you don't love it, you're not a real engineer, you're in the mediocre majority, and you don't deserve to be there anyway.
JamilD··on I Am Alex St. John’s Daughter, and He Is Wrong About Women in Tech
He's seen certain results, and been through certain circumstances. Unless he has proof that those circumstances -> results, making conjectures is exactly what he's doing.

This is ignoring the fact that effectiveness is not the only metric for a company. In Tim Cook's words, "if you want me to do things only for ROI reasons, you should get out of this stock".
