The idea is that such situations are non life threatening. The vehicle will pull over and wait for a human operator.

It's not crazy to imagine that computers could handle split second decisions better than humans but choose to bail out to the side of the road if there's something they can't handle.
I've been in this business for a long, long time and have come across all manner of innovations regarding network security.

Port knocking (which I think I learned about first at defcon ... perhaps 18 years ago ?) stands out as one of the very few things that made my network(s) substantially safer at nearly zero cost. I love, and continue to love, both the idea and the implementation.

Pay no attention to the nay-sayers and their comical straw-man argument against deploying port knocking by itself. Of course it's not deployed by itself - it is the last layer of defense-in-depth on top of all the other authentication methods you may be doing.

The substantive critique is that you add some amount of complication to your network and introduce a point of failure with knockd - and that is correct. I am happy to report that 15+ years of knockd in production use, all over the world, has produced exactly zero lock-outs or unintentional self-DoS.
Alright, without any evidence to back it up there is no reason to believe that you are likely to catch covid at home as anywhere else.

Edit: I don't even understand why there are 'political sides or movements' to this in the US.

You store the entire universe or whatever reporting requirement demand. You define the database structure based on the requirements of your business logic.

The frontend requirements can help define what api's are required but if you treat your database as dumping tables you limit what your data can do.

You add can add and remove indexes at any point. If you made a bad decision or no decision you would add those when more information is available.

At both AirBnB and Lyft, I promise you there is sufficient work.

I really despise this kind of 'pointed-her' writing style. It was popular in some older academic texts, and seems to be gaining popularity in blogs and the like in recent years. I have never written a sentence about a generic 'boss' as 'boss asks blah what do you tell him', nor was I taught it, nor would I expect to read it.

The genderless generic has always been 'they/them', it doesn't require positive action, nor discourse about a hypothetical generic's 'self'-identified pronoun. It has always been third-person, since long before anybody gave a shit.

The US is more "business-friendly" than Europe, but nothing compared to China or Taiwan for people with the right connections.

Occasionally you'll see unscripted interviews between a US reporter and a visiting Chinese business leader.

The US reporter always asks if the visitor will be opening a local factory (because the US is so awesome!), and the visitor starts looking around wildly and demurs, since they're just here to park money.

The thing that's a little different about Tesla in the US at least, is he is so incredibly fetishized by eg high-profile idiots: https://theoatmeal.com/comics/tesla,
or conspiracy nutjobs like the International Tesla Institute (http://teslatech.info/ttevents/prgframe.htm http://tesla.org/tesla_fair_abq.htm) publishing and promoting Tesla related conspiracies and hawking investments in snake-oil technology like Rand Cam engines, VMSK, and all manner of "over-unity" machines

There is a long long tail of edge cases that kill people.

When drivers go a few trillion miles per year in the US, any anomaly in your driving software is going to be measured in deaths per hour. There is a built-in human sympathy for accidents caused by people which will not be at all present with accidents caused by machines. You can't sure a maker for wrongful death by a faulty human, you can easily sue a car company.

It will just take one cute kid getting killed by an errant robot car to end the dream completely. Machines don't make human mistakes, they make mistakes that are alien and frightening, things you couldn't ever a person imagine doing.

The public will get scared and automatic driving will be banned.

For Tesla and everyone else doing unattended driving, it isn't a matter of covering the last few bits left, it's a matter of increasing precision by several factors of ten, and ultimately, I'm guessing robot cars won't be a reality until their intelligence starts to reach the point where people are asking questions about sentience.
I appreciate you taking the time to reply to this, but come on, “YC would not exist without Arc” is a definite exaggeration. YC’s impact as a platform is immeasurable, but the software is quite simple that could be coded in any other programming language just as well (I’d argue better since users wouldn’t be waiting now for new features to land if it weren’t for the language update).
Wait, what?

> It didn't matter [...] what tickets I closed, only whether I fixed that bug that was bothering that one big customer

That's what "closing the ticket" means, right? You close the ticket when the bug is fixed. This is what matters.

The deployments are much more roundabout metric -- maybe you fix 5 bugs with one deployment, or maybe your bugfix is big, so you had to deploy schema change first. Only JIRA tickets (of the right type/severity of course) show the business impact.
Normal distribution animated under different parameters
To be fair it did challenge an extraordinarily popular mainstream narrative that renewable energy is marching in to save the day from climate change without hardly any meaningful negative externalities. Of course the mainstream is going to tear it apart. They knew this in advance.

That said, knowing which statements are outright wrong is indeed valuable.

Still worth watching IMHO.
When number of deployments becomes an evaluation metrics, I can imagine an engineering culture like this:

- Dev rushes to make merge requests with the cost of thoughtful design and testing.

- Tension around code review turnaround time: how dare you take hours to review my code when I'm far behind in the leader board.

- Deployment has a bug? Awesome, now I'll have 2 deployments.

- Deploy faster and break everything.

Frequent and continuous deployment is good. Making it a metrics is bad.
I figure it all averages out. But when I pay an average price, I have no incentive to lower demand when prices are high or raise demand when prices are low, contributing to even higher average prices.
I greatly dislike Snow Crash: it feels like slogging through Leviticus, plus an astronomical amount of suspension of disbelief.

> I feel like firing a worker for running a NSFW OnlyFans account (or similar) would, if not should, run agrounds for sexual harassment or unlawful termination.

I don't think it should be considered unlawful termination. Someones behaviour outside work definitely has an impact on the business they're a part of. Unfortunately, whether we like it or not, SW has a very real stigma attached to it that could hurt the business reputation. That's a risk the business must take into account. It's like if someone were to attend white supremacist rallies on the weekends. It may not directly affect their ability to perform their role but I suspect we'd agree that it's justified if a business terminated someone for that reason.

Reputation is one aspect, but another aspect from a business perspective that I haven't seen discussed too much is the effect it could have on coworkers' performance. Say a woman has an OnlyFans and somehow her male colleagues find out. It would be at least a little bit distracting for them and could cause their productivity to drop. This is again a liability the business has to consider.

I'm not saying the stigma or termination is _right_ or _just_ in this case but it's just the reality of the world we live in and it will take generations to change that.

EDIT: To add a little bit about the sexual harassment aspect. I'm not sure where I fall on this. Say a woman works a side job as a stripper and one of her colleagues accidentally visits the strip club where she works. I would say it's not sexual harassment to visit the club the first time when they are unaware she works there. However if they were to solicit a private dance from her then I would consider that sexual harassment. I'm not sure exactly how that relates to viewing someones photos online accidentally vs paying for their only fans but I think it's somewhat similar. And what about repeatedly visiting the club/public photos? Visiting the club again probably is harassment depending on whether or not she is working that night but viewing the photos again probably not if she's not aware of it. It's a pretty large grey area with this part and it's difficult to form a solid opinion or even a rule without assessing things case-by-case.

Rails on Heroku is about the most inefficient combination you can get for a web server.

I've always thought of it as the platform you use for running toy apps with maybe a couple of dozen users at most and a low load. It's incredibly quick and easy to get a Rails app running on Heroku, a couple of hours at most. But you pay (in dollars and performance) for this.

Show HN: A Python Library to Send iMessages
I am so unabashedly excited for this to happen. I don't care about the habitual cynics. My only apprehension is that the director will try to relieve the absurdity by making it comedic, when the best way to handle it is to just have it be openly ridiculous without apologizing for it. Magical realism sets a good example for how to accept ridiculous, wondrous, and absurd things in stride.

Even if it 'sucks', I don't care, I'd watch this as a backyard play and be happy.
py-imessage is a lightweight library you can use on your mac to send iMessages.

It was originally started to build an API for iMessages which anyone could pay for; however, Apple has fairly aggressive detection policies that make it difficult to scale.

Today's nuclear reactors run constantly because the fuel is so cheap compared to the rest of the operations. They want to be selling kWh as much as possible because kWh is money. To convince nuclear operators to do backup, there would have to be some kind of market for their on-demand carbon-free characteristics. This would require market changes.

Of course, it's very possible for nuclear reactors to load follow from a physical point of view. Naval reactors load follow into battle mode quite impressively, and power stations could do the same, again if there were a market for it.

Even traditional reactors can couple to some kind of thermal energy storage system to allow them to stay mostly at 100% while the whole system load follows very nicely.

There are many exciting possibilities in on-demand, low-footprint, low-carbon energy with nuclear technology.
Your comments about the dynamics of HN are always fascinating.
In these times with the popularity of Westworld, Altered Carbon and the imminent release of the Cyberpunk 2077 game, we live in a golden era of cyberpunk-themed near future scifi. I hope that if they ever adapt the Gibson sprawl trilogy of books to a TV series, they don't ruin it.

First off, the article in question was an editorial, not reporting.

Second, the issue with the Henry Harpending reference isn’t that he’s a forever morally stained as a person. His career is built on bullshit theories, and he doesn’t get to wipe the slate clean with every article he publishes. It’s perfectly reasonable to redact a reference to his work if you have reason to believe his conclusions are tainted by ulterior motives.
Pretty cool. Did you bake the viz yourself? How does it work.. Can you explain a bit how you handle the sheer scale of it. And how the nodes are positioned - I can't imagine it is some sort of graph node attraction/repulsion algorithm as it will kill the server? Do you precompute?

Seems to me, he's an insider who is in the know and he's made an effort to explain why he sees it that way:

As long as we're on the topic, consider this: the software for both HN and YC was just a single Arc program (and not a large one) for the first 9 years of their existence, during which they went from nothing to massively successful to industry-changing.

I mean, you don't have to agree, but his opinion is probably more informed on the topic than yours is.

US laws generally only hold for US citizens and US companies.

The US had no issues using the NSA to spy on German IP and even bug the cellphone of Angela Merkel. And well, given that no consequences ever materialized, it won't seem like they'd need to stop at any time.

So given that, thinking that the US has "strong laws" is a tad naive. You know, since literally the opposite already happened.

Somewhere I had the idea concrete math was a combination of continuous and discrete, but I seem to be mistaken.

"When DEK taught Concrete Mathematics at Stanford for the first time, he explained the somewhat strange title by saying that it was his attempt to teach a math course that was hard instead of soft. He announced that, contrary to the expectations of some of his colleagues, he was not going to teach the Theory of Aggregates, nor Stone's Embedding Theorem, nor even the Stone-Cech compactification. (Several students from the civil engineering department got up and quietly left the room.)"

How to Build a Breakthrough – Mike Maples
The best way the halting problem was explained to me was to think of it like this: imagine you write your perfect halting detection program. It reads in the contents of some program, and returns true if it halts or false if it doesn't.

Now, all I have to do is write a program that includes an embedded version of your program. My program reads in the contents of itself and passes it to the embedded program. Now, all my program has to do is take the output of the embedded halt checker, and do the opposite; if the halt checker says the program halts, just keep looping. If it says I don't halt, exit immediately.

Now, you might think this is cheating, because it is using your own program against you. However, this is at the core of the problem; it has to work for ALL programs, even ones written with knowledge of your program.

>the free and fast flow of information enables decentralization

i was a believer. big time. starting in 99, was helping democratize telecom via VoIP. ate up long tail theory like candy.

but now i think we were incorrect in thinking the problem was only on the supply side - the monopolies (of that day) control of the supply side. that was a problem, but there are two sides of the hose.

the other side of the hose is us. 24 hours in a day. 1440 minutes. minutes increasingly bombarded as the supply side of the hose has widened, and the hose now lives in our pockets instead of on a piece of furniture.

i still believe decentralization will occur - simply because things do usually balance over time (or at least the pendulum moves back and forth) - but won't it take more than 'fixing' the supply side?
