It looks more like a way to simplify manufacturing. Put all the sensors in one factory-built topside unit, then bolt that to the car. Less labor intensive than hanging stuff all over the car,
cheaper in small volumes than integration with the car body,
and you can align everything during manufacturing.

This sort of add-on thing is temporary. Another generation and cars will have an equally good sensor suite, but it will barely show.

"You might think that increasing investment in public transit could ease this mess. Many railway and bus projects are sold on this basis, with politicians promising that traffic will decrease once ridership grows. But the data showed that even in cities that expanded public transit, road congestion stayed exactly the same. Add a new subway line and some drivers will switch to transit. But new drivers replace them. It’s the same effect as adding a new lane to the highway: congestion remains constant. (That’s not to say that public transit doesn’t do good, it also allows more people to move around. These projects just shouldn’t be hyped up as traffic decongestants, say Turner and Duranton.)"

In that case I'd vote to pardon the sockpuppeteer anyways. :-)
Zed Shaw's books remind me of Herbert Schildt. In fact, Schildt is also on that "to be avoided" list! Books from both authors are practical and interesting to read, but contain serious mistakes and omissions. Back in the days I learned C from one of Schildt's books, and I thought it was very useful. But now that I know better, I'd never open that or any other books he wrote. I guess, if you don't have any knowledge, such books look very appealing as a starting point. You quickly pick up some basic knowledge and practices. But later, it may actually be hard to unlearn all the wrong things that these books teach.
It's a slightly different situation. A mugger probably has the advantage of a weapon. Even if you have one as well, their weapon is already prepped for use, so trying to defend yourself against an already brandished weapon is not advisable.

Children in schools likely do not have weapons. It's hand-to-hand fighting with only weapons of opportunity (e.g. heavy books) available, and the provoking child likely isn't ready to use a weapon of opportunity.

Granted I'm not inherently saying that a victim should always deck a bully in the face. If that were the case, however, I'd say that child v bully has the advantage over the mugger v victim.

For me this is a huge plus.

I got one of the first batch of Echos when they were sort of an invitation-only thing. I wasn't sure how the voice interaction would turn out, but I figured it would at least make a decent streaming music speaker.

Ugh. The sound quality of the Echo was its worst feature for me. Really not what I expected from a speaker, especially after seeing their fancy descriptions of how they worked so hard on the sound quality.

It's boomy and muddy, not at all what I'm looking for in a music speaker. Oddly enough, I didn't see a lot of complaints about it, so I guess that boomy muddy sound is what a lot of people like? In any case it's not for me.

So yeah, having the Alexa functionality but being able to connect higher-quality speakers - and stereo too? That works for me.

"Real" is simply a relation between perceived and perceiver.

By your own argument, 1s and 0s aren't "about anything" either, they're just as devoid of intentionality anything "truly real".

I feel like 4% is way too low from what I've seen, but often the reason employees see big jumps is because the employer covers some flat amount, and then the un-covered part is what looks to be jumping.

So if your employer covers 750/month, say, and you were at 740 for 2014, then up 5% is 777 for 2015, then 816 for 2016. For you, that jump is 0 to 27 to 66. That feels like a lot.

Ask HN: Guidance on dealing with a bug bounty claim
Someone contacted us claiming to have found an account takeover vulnerability and asked for a bug bounty in exchange for sharing it. This is the first time I've dealt with this sort of situation.

We're a reference website. Our revenue comes from ads. 98% of traffic is anonymous, mostly from Google. Hardly anyone creates an account. We collect no sensitive information -- no CCs, only email, password, and optionally gender, birthday, bio, website. An account gets you access to our daily email and a user forum. Admin accounts can moderate the forum and edit a limited selection of ancillary content on the site. The real content is accessed through a separate account system.

Our engineering team is 4 people, none of whom are security experts. We've followed best practices as far as we know them. Never done a pen test or audit.

We offered $100, based on https://forum.bugcrowd.com/t/payouts-whats-a-bug-actually-worth-these-days/399/7

He responded with these prices:

- account takeover $1000

- sql injection $3500

- remote code execution $5000

So a big difference in prices. Also, I'm much more concerned about SQL injection and remote execution (which he did not initially mention) because they could to outages, which would be more costly to us than compromised accounts.

My thinking is to ask him what vulnerabilities he has found, so we can know what we might be paying. If it's just one account takeover, I'd probably then see if he'll take $500, or if not, give him the $1000.

He said he would be willing to share the exploit first and take our word that we will then pay him, which helps me trust him, though then I started to wonder if that's his intent and all of this is mind games intended to draw us deeper into some kind of extortion trap...so that's why I'm looking for guidance. Are there hidden dangers here? Should we cut off further contact and hire a reputable security firm to audit us? Or can I proceed based on my own/my teammates' judgment?

This happened to us. A Wells Fargo private banker offered a new Line-of-Credit. My wife said "no." We found a Line-of-Credit opened anyway. We complained.

Deep Learning Quickstart on AWS
Yes. The modern school systems are a criminal institution, teaching kids not to fight back against a lifetime of bullying and abuse. I am currently taking a previous landlord to small claims court (The had the temerity to withhold my entire security deposit and ask me for more to pay for expenses that are explicitly the landlord's under California law). When I have talked to my peers, I've gotten two reactions; One is a "hit them for all they've got", and one is "Why would you do that? They have money and power!" The former from my peers who were homeschooled (as was I, in part), the latter from those who'd gone through traditional schooling.

Modern US schooling is more-or-less intentionally training to not fight injustice, to not speak up unless spoken to, to fail to learn. Zero Tolerance policies are just one symptom. Spend some time in a classroom and you'll see the teachers favoritism, trying to be 'cool' and catering to the popular kids (and further alienating the unpopular ones), telling kids that they're wrong when they're ahead of the class and more right than the teacher wants to teach. Modern curriculums have been watered down and focus grouped into meaninglessness.

It's not the language. I don't really like Scheme (I'm more a Common Lisp guy). I would, however, really love to see Emacs without the Emacs Lisp limitations because everything missing from Emacs - at least to me - is performance. Guile looks like a good way to work around that.
If you believe he revealed this information for the purpose of debate, so the people can be made aware and have a choice/opinion in the matter, then you have to admit that he has acted on behalf of the country.

I would LOVE to have that kind of formally acknowledged scoring system. I could then actually weigh the decisions - "I'm currently at 523 risk points, which puts me at the 65th percentile of ethical divergence. I can sign this petition and go up 10 points. I'll only be at the 67th percentile and I don't plan on doing anything else subversive so I should be able to decay back down to below 500 before I need to book my vacation next spring."

Instead you have to guess "is this going to put me on a list? What does being on the list mean? Does the list exist?" Well, aside from the obvious list of the petition itself. You know what I mean.
If you can, try reading The Shallows by Nicholas Carr. It's not perfect, but it will get you thinking about how and why your attention span got to be the way it is. It will also give you hope, because you'll realize that it's totally within your power to change it (and rather quickly, too).

Your message started with "What wouldn't I give to have such attention span!", and it turns out that you don't need to give all that much. Getting started is difficult, though.

If you do start down this path, consider reading Deep Work by Cal Newport to give you some ideas about how you can use the focus and concentration abilities you're building. Again, it's not perfect, but if you take the book as a list of suggestions rather than a strict prescription of what you should do, you'll probably find that you can adapt its lessons to make your life better.
Indeed. That description mirrors what seems to happen with subsidized drug costs due to everyone having health insurance (speaking of the US solely).

Clearbit Reveal – IP Address to Company API
I dunno, when the article said "Tesla fanboys" that seems like a good indicator that the author is a bit biased against Tesla.
jsprogrammer has the merit of having actually done some calculation, which you evidently have not — although if you think resistance is a thing that inductance can have, maybe you are not in a position to do any calculations. Either way, you should rethink your attitude.

Naval railguns don't have the luxury of accelerating over hundreds of kilometers; they are optimized for muzzle velocity, not efficiency. The things I've seen videos of launch projectiles at about Mach 7.5 (2500 m/s) over about 7 meters. That implies an average acceleration of at least 45000 gees, which means that you're going to have to accept significant inefficiencies that you can avoid in a design that accelerates three thousand times more gently.

In practice, both rotary and linear electric motors typically have efficiencies of over 80%, often over 95%. The proposal in question is a 200-km-long linear electric motor running up the side of a mountain. It's clearly feasible, but it won't cost pennies per launch.

You do need to partially evacuate the launch tube to shove your launch vehicle through hundreds of kilometers of it.

It is not plausible that a naval railgun uses only 28 megawatts. Traveling 7 meters at an average of Mach 3.75 takes 5.6 ms; if the total energy output is 64 MJ, that's an average of 11.3 gigawatts†, which is a lot more than 28 megawatts or for that matter 78 megawatts. So what you do is you charge a big low-ESR capacitor bank (at less than 78 megawatts) before the shot, then discharge it during the shot (at tens of gigawatts). If you're doing that, though, you have no limit on how many railguns you can run from your 78 MW power plant, just a limit on how many total shots per second you can fire among all of them. Your entire paragraph on the topic is incoherent nonsense.

For comparison, a .22 LR 30-grain (1.94 g) copper-plated hollowpoint bullet traveling at 500 m/s out of a 510 mm AR-15 barrel only has at most 2 ms to accelerate to its final 240 J energy and therefore requires over 120 kW of power.

Classical mechanics are perfectly adequate for all of this. No relativistic or quantum effects are relevant. Your suggestion otherwise is absurd.

Calculations in units(1) format for those who want to check them:

(mach 7.5)^2/2 / 7 meters / gravity
7 meters / (mach 7.5/2)
64 MJ / (7 meters / (mach 7.5/2))
30 grains
510 mm / (.5 500 m/s)
30 grains (500 m/s)^2/2
30 grains (500 m/s)^2/2 / (510 mm / (.5 500 m/s))

† With constant acceleration the power output ramps up linearly and ends up at twice the average. With constant power the acceleration ramps down instead, which means that you have to start out at even higher accelerations to get the same average acceleration, and your total time in the barrel is shorter, so your average power is higher, although I don't feel like doing the simple calculus to quantify this at the moment. In either case you have at least a point where the power is a few times higher than this average.

I didn't go as far as PhD, but when I came out of uni, I knew nothing about life or work. I really wouldn't recommend anyone to try to launch their own startup right out of uni (especially not alone).

When I think back to it; if I had succeeded with my first startup right out of uni, I would have had a seriously distorted view of life.

My idea of 'hard work' has changed a lot since then. Staying up till 3am a few times a semester to finish an assignment is not hard work. Writing a 100 page thesis is not hard work either.

Even if there is some correlation between signing this petition and some of the things you say, the expected (in the statistical sense) damage to you is tiny compared to the cause in question and the principles, so frankly I think it is lame of you to even be writing about this, and I don't think it should be the top comment. It makes HN readers look like a bunch of #firstworldproblemers lacking perspective and fretting about minor inconveniences to their privileged lifestyles.

Actually, I have found that my (young) adult life is the best time of my life and I have a giant excess of free time.

I'm very lucky to be able to command a high hourly rate for software consulting. So I can work <40 hours a week and still earn enough to outsource 90% of the items on this list (cooking, cleaning, etc.). I definitely have way more free time now than I ever did as a student.

Seriously, people always act as though students have an easy life. In my experience, I was much busier and less happy when I was in college. Not to mention that real work is, for me, much more meaningful than the fake work which constitutes most "education."

Also, technology really has reduced a lot of these time demands. If you're still manually paying bills or balancing your finances, you really need to automate that. There's no reason to spend more than 15 minutes a week on that sort of thing.
