I'm assuming Level 4 is what Musk means by Full Self Driving. The bar to be passed is then

"No driver attention is ever required for safety (...) self-driving is only supported in limited circumstances (e.g. geofencing), and when these circumstances are no longer met the vehicle must be able to safely abort the trip, e.g. park the car, if the driver does not retake control."

How would that work if you're out driving on the highway, and it starts snowing hard so the car can't see anything? Just park on the highway?

If your car can't safely handle such a scenario, the automous feature would have to be "season-fenced" in addition to geofenced.
The earth is in a state of constantly flux, but when food supplies dwindle, the end result is famine, war, bloodshed, chaos and death.

The earth will recover from humans, but I don't want to be around for a mass human extinction.
And heading to 10 billion. On the back of unsustainable use of soil, water, fish, natural resources in general, antibiotics, antifungals, etc. That worries me too.
I don't think its fair to judge the worth of someone's degree simply based on how much they earn.
I had that particular line in mind when I wrote my comment, and I stand by my statement. The most that Nature offered was to maybe publish a letter to the editor. A letter to the editor is not the same as an article in the same publication.
Elon Musk is noted for his premature optimization.

Case in point: both the Gigafactory (vastly overbuilt for the quantity of batteries actually produced) and the Alien Dreadnought (vastly overbuilt for the number of cars Tesla current produces...assuming that Tesla is ever able to get the fancy automation working). Boring Co digging a two-mile tunnel in West LA without bothering to learn how to pour concrete smoothly, or to make the "rails" the proper width, or learning about ventilation, or access points....
In other words, it's not gmo, but syn-bio.

(Of course, pretty much everything in the US without an organic label is an unholy mishmash of gmos, pesticides approved by captive regulators, and untold gallons of antibiotics. So probably doesn't make much of a difference anyways...)
This is not a substitute for debug-level logging when you need it.
Besides private universities, public universities also charge fees for numerous things. In some states where tuition is controlled by the state, this is how universities get around tuition caps when they need more funds than tuition and taxpayer dollars can cover.
I wouldn't really call that middle class then, but maybe
> 12% of the population will find themselves in the top 1% of the income distribution for at least one year

That is just wild. I wish they dove deeper into the data here. The top 1% of earning, based on a quick google, is 1.3m/yr. That's a lot! Are there, say, estate windfalls pushing people around to cause some of those blips?

Also, this article fails to separate income from wealth/assets, which seems to be a common pitfall in this kind of conversation. Many of the people with the most wealth are not those with the most income. So while there appears to be lots of income volatility, I would be interested in seeing the same thing for wealth over time.
No, I wouldn't even say Texas is close to 100k starting. Lower end of the bell curve is closer to 65-70k in Austin. Average (across all levels of seniority for software engineer) likely falls somewhere in the low 100s. Just basing this on a quick search and my personal experience working in Austin around 2012-2015.
I don't think any one is doing this. This is the point Karpathy is making. Vision is essential and needs to be perfect and also has all the information to recreate the 3d environment. That's why lidar is not required and is expensive.
Yup, I still think that you can likely solve the halting problem for "useful" cases. The cases where you can't you probably should change your code anyways, since odds are people can't reason about it either.
No, I'm asking what percentage of all the millenials in the US work in those jobs, not what percent of those jobs have millenials working in them.
Pricing leverage is a factor, but the major thing for me is that I usually don't like working with a client for more than 3-4 months. If you go beyond that time frame (in my experience) you usually see dependencies between the freelancer and the company cropping up, which I want to avoid as much as possible, as that often leads to the expectations of either party to be hurt sooner or later. This also puts me in a position where I can transition to a more interesting/lucrative client very quickly, with the old client still being happy.
Fun fact! Philip Roberts, who started Buca, sold it and started what is now one of the best steakhouses[0] in the country. It's the cash cow (no pun intended) for the other restaurants in his restaurant group Parasole, and is easily the highest-grossing restaurant in Minnesota.

They're "sperm-to-table" and a treat to dine with. I'm there too often.

Apple is the perfect counter example here.

Apple wasn't the first company to make an MP3 player, but the generic term is basically 'iPod'.

Apple wasn't the first company to make a smartphones or touchscreens, but the generic term for a touchscreen smartphone is basically 'iPhone'.

Apple wasn't the first company to make a tablet, but the generic term is basically 'iPad'.

Apple didn't invent high resolution displays for personal devices, but the generic term is basically 'Retina display'.

We can go back in time, too. Apple didn't invent the mouse or a GUI, but lots of people pointed to the Macintosh as inventing them.

What these people are doing takes tremendous courage. Posts here over the last few months have many wondering why people in Facebook and Google are not speaking up and in this instance we have some genuine dissent, activism and protest at least on one issue.

But history shows dissenters are always a tiny minority, from the initial struggles that secured labour rights to equality for women. Most people will conform and fall in line for whatever reason, and in these cases there is unfortunately always resentment against the dissenters from those who fall in line.

In most other situations you would expect the early dissenters to get growing unequivocal support as more people find their compass and courage by example but there is a moral crisis in the software community and it looks these individuals may not get the widespread support they need.

But these kind of incidents will make it increasingly difficult for Google leadership and others who work there to go to events, meets and publicly talk about ethics and others issues these protestors raised.
You know, it's not as if we can't do both.
If I'm expected to pay for it with tax dollars, that's the only possible way to view it. I'm not going to subsidize someone "finding themselves".

> He also rails against private state specifically. I assume again that he means private mutable state. This is generally a bad idea and is accepted pretty uncontroversially as a bad idea.

Here's a program that has some mutable state. Do you want that mutable state to be private or public? Do you want anybody to be able to change it, or do you want all changes to have to go through public methods?

Given that there are programs that necessarily have mutable state, why in the world would you not want that state to be private?

It’s hard to tell because there isn’t anything concrete provided.

That said, if this is a traditional web app, this smells to me of a poorly designed application. It sounds like they’re doing on the fly compilation of static assets or something crazy like that, and in any event need to reduce the total number of requests per page or resource and look for opportunities to make things static or cached?
Most Teachers Don't Teach Climate Change; 4 in 5 Parents Wish They Did
The term "millionaire" is very dated.

It was first coined in the 1700s and first popularized in American culture as early as the 30s, so really when people envision that "millionaire" from their childhood or from their parents' minds they're really thinking of a decamillionaire in today's dollars.

When you frame it like that, I'm not sure if any millennial thinks that will happen.

Really nice! The Result reminds me of Validation from Scala.

In Scala you return a Validation that is either a value or an error, and can pattern match on it. Also: trySomething().orElse("Default value")
Yes, we implemented simple physical solutions such as wipers and window heaters in cars to maintain vision for drivers. What we didn't do was implement lidar to aid human drivers.

Simple physical solutions are available if necessary for the cameras too. I don't have a tesla so I don't know what measures they use to keep the cameras clean but I'm sure they've thought about it and designed for it.
So instead of me directly paying just for my own education I would have to pay for everyone else's education in the form of taxes? Freeing up what I am currently paying for student loans would be nice, but if you take more money from me to subsidize ALL public colleges am I really gaining anything? Sure this is a good talking point for her and the progressive left, but realistically it isn't a feasible plan.

Sounds like a real outlier that you lost that much of a class. I guess the car accident is actually one event, but it's still a big and shocking loss.

For me the surprise was that two of the four were murdered. Your chances of dying at all in a given year before 40 is something like a quarter of a percent. Your chances of being murdered has got to be some tiny fraction of that.
Does anyone know how Lidar would work in the future when many other vehicles are also using lidar?

From working with some different types of photo sensors (CCD, avalanche photodiodes, photomultiplier tubes), you might imagine that incident light from another car's emitter would be much brighter than the reflected light the lidar sensors are reading and cause saturation.
Oh yeah, that's likely it. Thanks!

The reporting on this plan so far seems to be very light on the details of how the federal government is going to eliminate something it doesn't control (public university tuition).
It's a benefit of being a member of a wealthy society, as are other non-free things like public education, libraries and clean water. Societies strive to benefit citizens more over time, not less. That's how societies work, and early humans formed tribes because of the mutual benefits.
> they would conduct petitions via anonymous voting mechanisms (e.g. internal surveys) that let all employees vote for/against/indifferent, so that a broad voice is heard and not just a skewed vocal minority that faces no consequence.

This is exactly what I want from petitions, online or otherwise. "Sign this if you agree" is not a good way to figure out what is best for all compared to "Do you agree or disagree".

There are so many petitions I see where I disagree with the petition, but the petitions aren't designed to include dissenting voices. Honestly, as a society we should reject all petitions that don't leave room for the representation of dissenting views.
I feel like some of these examples could be US-centric phenomena. We in the US tend to confuse brand names with product categories, and in other markets the Apple brand doesn't have the same dominance in most of these.

That was a decision for the people who agreed to pay them 50k to make. They did and now it's on the purchaser, not the people who made informed decisions and didn't get themselves in debt they can't afford.

Put it this way, if you're tight on money and you max out your credit card for a vacation across the world, is it worth it? Obviously not but you can't expect tax payers to bail out poor financial decisions.
Ask HN: Default h5 and h6 fonts are smaller than normal text in HTML/CSS – why?
Maybe HN can help solve this little mystery. The default font sizes in HTML have, since at least 1998 [1], been .83em and .67em for h5 and h6, respectively, making them smaller than normal text by default (1em). This leads to the bizarre situation that without any styling, the h5 and h6 headings are smaller than the text they head!

Does anyone know why headings were made smaller than normal text? I bet the answer is buried in some mailing list from the mid 90s, but so far my searches have not been fruitful. Perhaps someone here was around at the time of, or was even involved in, this decision.

Ah ok. Great to hear!
Agreed - it certainly is rewarding in itself to get to the next level, but that's precisely it: the means become ends in themselves. I stopped using stuff like Arch Linux a while back for similar reasons.
Hey HN, this is an article we wrote about things to watch out for as you develop your machine learning models and deploy them on production.

We realize that it's really important for data science, product management and engineering teams to discuss and ideally monitor any new or any changes in data capture and processing that feeds into a machine learning model.

Before or after taxes? 30k before seems rather low for western Europe
Yeah I don't see how it is either/or. Autonomous driving is so hard surely you need all the sensors you can get! Maybe when it is working really well you can optimise the cost and only use cameras, but we are decades away from that.

I suppose if you want to use customers as guinea pigs you do have to have a low-cost solution first, which is why Telsa are advocating it. I'm sure if LIDAR were cheaper I'm sure they're be using it.
I certainly agree with the notion of trying to affect change from within but how viable is that at a company like Google? In looking at just the recent past for example we see sexual harassment mishandling, work on censorship-enabled search, Pentagon contracts, double Dutch tax avoidance schemes etc.

At some point don't you conclude that the distance between your own value system and that of the corporation you work is just too great?

> As someone else mentioned, that sounds more like a work environment problem.

Have you ever used any API by, say, a major cloud provider? For example biquery and google docs are both a buggy mess despite being high profile, long established products. Using libraries like pandas is an exercise in figuring out by trial and error how to get it not to corrupt your data and which of the recommended ways of doing things don't involve a 2 orders of magnitude performance defect.

I'm in fact mostly using "repl"-driven development for these types of problems, but of course it's inferior to what I mean by debugger driven, a crippled subset to be precise. The scare quotes are because most languages don't have real read-eval-print-loops either, but something less powerful.

Unfortunately to the best of my knowledge there are basically only two languages which support this: Common Lisp and Smalltalk (maybe factor or something else really fringe also does) and I haven't used either in years. What I mean by debugger-driven is that you can literally write your whole program without ever restarting it, from the debugger. By contrast python can't even properly reload a changed module definition.

Interestingly it's hard to google good explanatory links, but the point is that you can write some code, run into a problem, and fix the problem right there, in the debugger without aborting the current execution or unwinding the stack.

Common Lisp and Smalltalk both have a bunch of unique features that make this type of thing very powerful, for example some function calls another function that's not defined. In python you'd be screwed at this point and restart your program from scratch. In Common lisp you can just write the missing function, compile it and continue the current execution frame as if nothing ever happened. This is because Common Lisp, unlike any remotely popular language allows for resumable exceptions where you can continue from just before the error happened (it also has the usual stack unwinding exceptions).

Here's two examples I found :

Concerning low-overhead, selective tracing (that you can run in production without fear of bringing the system down): erlang for example has nice support for this, see e.g. https://github.com/massemanet/redbug (although again unfortunately it will be difficult to grok without any prior erlang exposure).
well if you go to a school like NYU or USC and pay 80k a year for tuition and room and board, you're paying more for the lifestyle than the degree.

Arguably it's worth it to some people. At NYU you can get a room right on Union Square or Washington Square Park for instance.

Work has a mission, which is to create value for customers and charge a price that creates income for the company (and transitively for shareholders, employees, etc.). The justification for saying "all work is political" is basically the same as saying "all actions have impacts". Sure, all actions do have direct and indirect impacts, but then we don't need a word like "politics" to exist in our dictionary do we? After all, if anything is political, what differentiates this word from other language we already have available to us? As such, I reject this notion that tries to position employee activism as being somehow similar to otherwise everyday corporate operation.

Expanding on this further: I think colloquially, most people would agree that certain actions are explicitly political and certain ones are not. I do not view Google taking on a military contract as a political action, but rather a normal, expected action for an entity that tries to create value for others. The neutral-most stance, if any, is for them to accept all willing clients. On the other hand, employees protesting because they disagree with the actions/impacts of one of Google's clients, or employees who disagree with a specific application of a technology (which others unrelated to them see value in), are bringing personal judgment, personal opinions, personal values, personal morality, and personal politics into the workplace.

The reason I label these as 'personal' is because these employees are imposing their worldview on the company's decision-making, and overriding the democratic/distributed nature of transactions taking place freely in the market between two consenting entities (the corporation and its clients). Those transactions are better and more-neutral measures of value than the voice of a small but vocal minority acting within the company. Effectively, such employee activism is a corruption of the notion of creating value for others (or others recognizing value in your products), and therefore not aligned to what the corporate mission is. Since it is not aligned to the corporate mission or the job the employees are paid to do, it is personal or political but definitely not normal or acceptable, which is why disciplinary action is justified.

Americans do vote for more taxes on the rich: https://stats.oecd.org/index.aspx?DataSetCode=TABLE_I7.

The average top statutory rate (federal + state) is 43.7% for 2018, slightly on the lower end of a cluster ranging from Switzerland (41.7%) to Ireland (48%), including places like Germany, Italy, Spain, and the U.K.--which together have 63% of the EU's population. Taxation of rich people in the U.S. is squarely within the mainstream for developed countries with robust welfare states.

Where the U.S. departs is taxes on everyone else. Compare the tax revenue statistics of the U.S. (https://www.oecd.org/tax/revenue-statistics-united-states.pd...) with those of Spain (https://www.oecd.org/tax/tax-policy/revenue-statistics-spain...). Spain and the U.S. have almost exactly the same top marginal rate (43-44%). Spain takes in a much larger share of GDP (33%) as taxes versus the U.S. (27%). What is the difference?

- Spain gets slightly less taxes from corporations (7% versus 8%)

- Spain gets less taxes from income taxes, which are progressive (21% versus 40%)

- Spain gets way more taxes from social security contributions, which are regressive because in both countries they are subject to a cap (34% versus 24%)

- Spain gets way more from excise taxes, which are regressive (29% versus 17%)

Imagine if the U.S. wholesale adopted Spain's tax system. Total tax revenues would go up by $1.28 trillion per year. But income taxes, paid primarily by the rich, would fall from $2.1 trillion to $1.37 trillion. Excise taxes, paid primarily by the poor and middle class, would go up from $890 billion to $1.89 trillion. Social security taxes, paid primarily by the middle class, would go up from $1.26 trillion to $2.22 trillion.
No, you subsidize people doing poorly paid but highly educated work in fields like public health work, education, and non-profits. You also subsidize people getting the basic education required for many jobs.
