>I think the answer is that "just building in costs" is actually rather hard to get right.

Exactly. It is almost as if we need AI to resolve the problem of properly supervising AI's training. I was wondering if the solution would be to add to classic actor-critic system a third network called a supervisor. The difference between the critic and supervisor would be architecture and the goal of the supervisor would be avoidance of those "terrible" outcomes. Some experiments would have to be run to decide if this approach is viable or do we have to continue tweaking cost functions.

Regarding Safety Gym I'm not sure how what they are doing differs from simply hard coding into your training procedure a series of checks for probability of hitting disallowed states in next step. For example in their example of a robotic arm that is trained with humans around the hard coded algorithm could track people around the arm's work envelope and when some person is detected as approaching it gives the robot a cost penalty. Also, for this to result in trained avoidance of people the network would have to have sufficient inputs to detect people by itself.
> I have no idea how to type emojis on Linux (with a barebones tiling WM)

You can copy and paste. In the context of this project, the small, fixed set of symbols (not emojis, but whatever) makes a lot of sense, and the code comes with an example that you can copy from. I would guess that this works even on Solaris or in a decent editor on GUI-less FreeBSD.

As for using, I don't know, "thumbs up" and "thumbs down" symbols in place of "true" or "false", sure, that would be excessive.
try/throw/catch work at block-level. panic/recover are not an option until function-level
[a late answer, but now the threads is old enough to legitimately get lost on tangents]

Are you talking about a "full hand rest" mouse? Because there is no static load on the arm when operating a mouse that is hardly ever touched with more than fingertips, while the base of the hands is resting on the table.
GEB is excellent as a pop-science/pop-philosophy book, but (like most pop-sci books) it's terrible for actually learning any subject. You need more than one proof every 200 pages.
A lot of the technology it uses was developed by and for NASA with NASA's money.

While Dragon may be standing on the shoulders of giants, isn't that equally true of the Orion program? I mean, sure, SpaceX has benefited from past lessons, but so does the current NASA development program. Those giant numbers quoted for Orion/Constellation surely don't include moneys spent on Apollo, Space Shuttle, etc.
I answered "Yes," but only in a convoluted reading of the question.

Most accurately, HN is the only online service I use that is mainly a source of news.

Put another way, I come here for the information and discussion, and it just happens to be a news site[1]. Before HN, I went nowhere (online or offline) explicitly to obtain news. After HN, I expect I will, again, simply do without.

[1] Which suits it well, IMO. I always flag old/repeat articles.
Wouldn't SOX also come into play?
In the comments the author noted that he'd "never met a Lisp that [he] liked". Maybe that's why he doesn't see the value in learning something from writing a basic Lisp yourself.
It's also important to note that editing is not just making sure your copy is grammatically correct -- that's called copyediting, and you can pay for that by the page. It's pretty easy to find a copyeditor.

A good editor is someone who knows good writing and will tell you if you're producing crap. They should also be able to tell you if you're writing to the current zeitgeist.

There's value to having good editorial support but, IMHO, it's not worth signing over all your rights and earning potential.

You can outsource all phases of editorial and production, the big houses already do.
I keep telling myself that I need to explore "real" news sites like the BBC or Guardian (or...), but never quite get there.

I primarily stick to Slashdot and HN but know full well that the views in the comments of the two sites can sometimes be very detached/different from the rest of society.

While this isn't necessarily a bad thing, it is something to be careful of and I'd hate to find the day all of my own opinions fit a site perfectly.
Linode 512

1. Awesome support.

2. I got a free voucher, so I essentially have a free server for 5 months. I'm actually considering just paying them anyway.

3. Linode Library is amazing for a Linux noob such as myself - http://library.linode.com/ - Had an OpenVPN server setup and going within an hour. It's a great way to learn Linux, etc

4. Freedom of use - no restrictions on what you use the server for as long as it isn't illegal.
I think the problem with voice control is that if it's not 100% perfect it's completely frustrating. When I encounter Interactive Voice Response systems, I'd much rather "press 1" than have to repeat myself three or four times.

That being said, if the technology improves to the point that it works the first time, then I see it being incorporated everywhere (cars, microwaves, lights, thermostat, etc).
Absolutely, tooling is a hugely important in making or breaking any programming language/framework.

In the end it all generalizes to "Your product is only as good as its experience".
They ticked all the boxes until they mentioned Dyson Spheres. Then it all started to read like GPT-3.

There are very few certainties about the future of technological development, but one we can hold onto is that nobody will be building Dyson Spheres. Dyson himself has said the notion is wholly absurd, and is not in fact what he meant at all.

Cosmic microwave background is already below liquid-helium temperature, and is anyway easy to shield against. Almost all of the universe is at cosmic-microwave temperature; you just need to get some distance between yourself and stars; or galaxies, if you don't trust magnetars in the vicinity. Bring along a Jupiter if you will want protons later.
I hate to be negative, but the market has decided it wants un-repairable and un-upgradeable devices.
The publishers definitely take a risk, but back when I was involved in this, way before ebooks, the biggest part went to the booksellers. IIRC I got about 6% on book sales.
If I ever do anything like that again, I'll be self-publishing, because the contractual shenanigans have left me very wary about dealing with publishers.
Thanks, really appreciate it! We support about 125 languages and variants.
You do realize that SEO to rank in search results and posting on social media (or hacker news) about your product is marketing? Without marketing how do people find your product?
How do you get better labor laws without middle men groups lobbying? The same Amazon workers have neither the time nor energy themselves.
I've been running Nginx for more then 10 years now... Is there anything "new"? I know about serverless, but anything else that makes the webserver part easier and safe?
I'm sure it's a nice visualization, but unfortunately I'm only seeing a white gap between the two sliders and tapping randomly doesn't seem to have any effect. I assume I should be seeing a polynomial graphed even before doing anything.

Why would capital police escort armed rioters into the Senate building for "safety" if their job is to ensure the safety of the Senate building, Senators, and staff?

This is a backwards argument. The police didn't do their jobs. They were even seen taking selfies with the trespassers: https://twitter.com/bubbaprog/status/1346920198461419520
Thanks for the reply! With that CrowdStrike founder Dmitri Alperovitch quote in the article

> Compromising and introducing a back door into a build environment such as TeamCity is the holy grail of a supply chain hack. It can allow an adversary to have thousands of SolarWinds-style back doors in all sorts of products in use by victims all over the world. This is a very big deal.

it read like this was much more widespread than I'm hearing now. The NY Times has even gone back and edited the title, replacing "Russian" with "widely used." I hope the editors have another take at this before it gets republished on all the other news sites ...
Yes, I do. I feel secure in using AES and still remain skeptical of its creator. The NSA does good things and a whole lot of bad things simultaneously.
No, you as Americans have accepted EULA's as-is. This is a solved problem, and you just need to import the related laws from Germany.
Still single digit level nanosecond precision sounds marginal. 1ns = 2 clock cycles at 2GHz.
It's kind of like this meme with two people seeing a number, one saying 6 and other saying 9 - except in reality it's neither; it's a piece of a shadow of a large pretzel. Real-life issues are complex, multidimensional beasts. Disagreement between honest people often comes from them not realizing that what they know and believe is a projection, a dimensionality reduction. Same is with the news - they usually offer what amounts to projecting a 42-dimensional object into two or one dimensions.
I bet today's event's will make Chuck Schumer think twice about eliminating the filibuster.
Not to mention the stunning number of people with college degrees who don't think loans should be paid back.
I think Prof. Feamster does understand that (he says "Comcast arguably (and, empirically speaking, as well) has more market leverage: They can afford to ask Netflix to pay for that direct link—a common Internet business relationship called paid peering—because they have more market power.") but he is taking a faux-objective, "teach the controversy" approach. I've seen the same philosophy in papers from his students.
related question: spectrum pushes fiber where i am located, but there is no way to bring fiber into our residential unit/building. i guess they mean fiber to a local hub or something, then cable to our unit. isn’t that what they do anyway, and unless you have fiber into the unit, offers no improvement?
I figured I'd check out Slashdot after a decade-plus long hiatus... clicked on a comment section to be greeted by a pages-long scrolling message with some QAnon drivel and dozens of huge ascii swastikas. Flagged it. Never got taken down. Same message in damn near every other story on there. Ok... bye. It's not like they're just being inundated and not able to respond— that site is so low-volume they could hire a task rabbit for $5 every day to go through and delete all of the swastikas and it would drastically less off-putting. Or maybe just require logins? No allow monospaced text in posts?

Not sure what signals you'd need to realize your formerly excellent site is a giant moldering dumpster and you should just throw archives from the first 15 years somewhere and call it a day— but I'm pretty confident they were just ignoring those signals like 10 years ago.
I meant in the sense that unsigned integers have C-specified defined behaviors for conditions like overflow that are undefined for signed integers. That said, if you bothering to create these integers types (e.g. the common MAX sentinel idiom), their behavior is often fully defined. If you go crazy with metaprogramming, type inference, etc in recent C++, you can often verify at compile-time that these conditions will not occur across arithmetic operations, though this is a lot less trivial.
uBlock might stop you. It's certainly consistent with their philosophy to block all analytics, even homegrown and not shared across sites.
Yes, I never trust what company people say about their workplaces, unless: I know them, it's in private and they have sharply critical minds. (Usually called "disgruntled".)

- If I don't know them, they have little incentive to tell me the truth.

- If it's not private, then selection bias: glowing affirmations (or pseudo-critique: "Yeah we have our problems, but...") will obviously be the voices we hear. Not only are those maybe rewarded, but cold enough critiques are swiftly punished. For obvious reasons.

- If they're not sharply critical types, they miss what should be obvious, because they drink the koolaid or are just plain fine with whatever silliness.

(Why the emphasis on critique? Because one's job is solving problems, and real companies have such egregious problems. I'll accept fairly wrong critique in preference to correct bragging, because critique's usually missing and at least something not-too-wrong is a string to pull on during research.)
amen - even small 3k products websites are about far more than OOP just knowing how all your pages are generated is a big ask fore most sites.
Bluespec is a language that's getting attention from academia and industry: http://www.bluespec.com/
Let's not turn HN into Tumblr.
Maybe it will balance out all of the false positives from bots? I get so much fake traffic, I don't know the real numbers anyhow.
> If you can't tell who to be nice to, you have to be nice to everyone.

This (more or less) works the opposite way, too. Taking an example I know about, in Brazil, you can't often tell who is going to try to take advantage of you (in business) but enough people have tried in your past that you come to the conclusion that everyone will at least try in the future, and therefore you act accordingly.

It's really frustrating to have to treat people with your guard up when signing a contract or talking through specifics during a deal, but you learn to recognize advantage-takers and even to pretend you are one, too. In doing so, the other person will recognize they can't pull the wool over your eyes either, which puts you both on a 'level' playing field.

This isn't just something I've experienced but also something I've been told by many others in Brazil. There's even a 'law' about it, called Gérson's Law [1], which essentially states "if there's an opportunity to take advantage, go for it".

I'll reply to myself because I've just explained this sentence to myself:

Because the government needs to run a deficit, it's the only way to inject financial resources into the economy.

The central fact of economics is: The economy grows. The number of people on earth is still growing. The productivity of individual workers is still growing. We are capable of making more stuff in every year than we did in the previous year.

Now, suppose the supply of money were finite. But the amount of stuff being made keeps getting larger. So, every year, the price of everything goes down, because there's an ever-larger supply of pizza and beer but a constant amount of money.

But this creates a serious problem for the economy. Because now we've got deflation. And that produces a really big incentive to save. Too big an incentive. Everything will be cheaper tomorrow, so every individual benefits by burying money in the backyard and spending as little as possible.

But as people bury more and more money, the economy shrinks, because there is less and less money to spend, and everyone is trying to hang on as long as possible without spending anything. You end up with lots of people sitting, unemployed, with tools idle, and resources idle, and money buried in the backyard, staring at each other and waiting for someone to make the first move. Because, thanks to deflation, the first person who spends anything is a relative loser. And now your economy has deadlocked.

And that's why the government always runs a deficit, and why the inflation target is always higher than zero. The government prints money to make sure that the supply of money stays good. This produces some amount of inflation, of course, but the growth benefits of liquidity outweigh the inconvenience of having to do something more interesting with your money than bury it.

(Why don't more people understand this? Partly it's because the growth of the economy is a historically new phenomenon, dating back only about 150 years. Before that, as far as we can tell, human economic production per capita barely grew throughout millennia of history:

http://www.amazon.com/Farewell-Alms-Economic-History-Princet...

The other cause for misunderstanding is that if you, say, define "gold" or "silver" as equivalent to money, and your society's economic productivity grows, but society's ability to dig up gold or silver grows exactly as fast as overall productivity at all times, the currency magically manages itself. Because of this, for a hundred years and more of the Industrial Revolution the world managed to struggle along with a gold-based money system. But, of course, the gold standard was abandoned when people finally figured out that this process is very haphazard -- indeed, it cannot be controlled. You can't discover gold overnight, but sometimes you need more money in the economy overnight. Like now, for example.)
distance to the alarm clock has no impact on my ability (or rather, lack thereof) to get up in the morning. I will walk through two rooms, turn off the clock (apparently I'm cogent enough in the morning to figure out that snooze means another infernal buzzing sound in 15 minutes, so I turn the alarm off instead), slouch on the couch, and pass out again. It can be so bad that I will dream about getting up again and going to work, only to wake up half an hour after my necessary leave-home-for-work time
I did indeed remove it. We use it to filter the masses on Craiglist, but I find it less compelling for the jobs page itself.

Though considering this audience maybe I should have left it in.
Feels extremely relevant after pulling an allnighter and sleeping 12 hours after that. And now I should head to work...
I think you could safely substitute "Your average American" for "PBS fans" and have it stay just as true. 20+ years of Kevin Mitnick and WarGames haven't done term any favors.
...which I promptly added to the post. Thanks Tom!
I'm guessing he means "raise the age when folks begin collecting social security benefits"
They seem, unfortunately, correlated. Certainly, there isn't any easy causal relationship. And actually, looking at it more -- I may be wrong. Here's a real-estate price map for San Francisco:

http://www.trulia.com/home_prices/California/San_Francisco-h...

But by the logic of the westerly (east-blowing) winds, however, places in SF like Hunters Point, etc., were probably not as attractive real estate locations originally, and probably that led to some vicious cycles, etc.
Why was there any relation to short selling regulation as a lesson learned from the trade in question? Wasn't it more about the policies of the U.K. leading up to the trading opportunity, rather than any abuse of 'short-selling'. (Plus given it was currency markets, rather than stock markets...)
Nice animations.

How do you keep a broken or hostile node from advancing the sequence number to the end of the sequence number space?

There's an algorithm from one of Butler Lamson's grad students at MIT which fixes this, but it seems to require one more message per cycle. (http://pmg.csail.mit.edu/~castro/thesis.pdf) That paper later appears as a Microsoft Research paper on how to make an NFS-like file system with this consensus properly. Did Microsoft ever put that in a product?
His memory was when the phrase "global warming" became "untenable and changed to "climate change"". That's what's wrong. The phrase "Climate Change" was not introduced late on because there was some problem with "global warming". It's been in use from the start.

If he'd said "unfashionable" rather than "untenable" then he'd have been closer to the mark.
If you make money it's probably a good idea. If you lose your customer's "groceries" and they sue, it's going to be against you personally instead of the company. If you incorporate, they can only liquidate the company's assets and not yours (if you're an LLC)
Wow. This is a great article. James Fallows has been writing about these issues since the 1980s and knows them well.

I was astonished by this paragraph in the article, having many relatives who are farmers, and knowing in a general sense how rare farming is as an occupation in the United States: "Now the American military is exotic territory to most of the American public. As a comparison: A handful of Americans live on farms, but there are many more of them than serve in all branches of the military. (Well over 4 million people live on the country’s 2.1 million farms. The U.S. military has about 1.4 million people on active duty and another 850,000 in the reserves.) The other 310 million–plus Americans 'honor' their stalwart farmers, but generally don’t know them. So too with the military. Many more young Americans will study abroad this year than will enlist in the military—nearly 300,000 students overseas, versus well under 200,000 new recruits. As a country, America has been at war nonstop for the past 13 years. As a public, it has not. A total of about 2.5 million Americans, roughly three-quarters of 1 percent, served in Iraq or Afghanistan at any point in the post-9/11 years, many of them more than once." I know some veterans of the recent long-term war too, but indeed the United States doesn't feel at all like a country in which the public is preoccupied with the ongoing war. I have been an American who studied abroad for three years. I had no idea that that is now more commonplace than enlisting in the United States armed forces.
1. Overflow doesn't cause memory unsafety in Rust, so trying to imply that it's not a genuinely safe language is incorrect.

2. Even if it did, saturating on overflow is exactly as safe as trapping, and has the added benefit of not introducing an untold number of new ways that your program can panic.

3. Trapping on overflow is oversold as a solution to logical errors because you're still opening yourself up to approximately four billion (or 18 quintillion, depending on width) invalid states before your program bites it. If you want a real solution, stick numeric bounds in your type system.
As waterlesscloud notes, I'm talking about the popular use. I'll turn around your IPCC argument: anyone with a clue would realize there was a distinct chance another change in the party line like the cooling to warming flip would be required by the short term temperature record, so the IPCC merely future proofed their gravy train.

My calling was science. Finances prevented me from fulfilling that potential, which is why you'll find me here in Hacker News.

Saying "just wrong" is no more convincing than my bald assertion of what I thought was generally accepted, so for example use a search like this one: https://www.google.com/search?q=global+warming+stopped to find deniers like the BBC, Wikipedia, NATURE (http://www.nature.com/news/climate-change-the-case-of-the-mi...), National Geographic, and The Economist in the first two pages of my results....
The BBC and in part Ch4 are funded by the license fee and therefore don't need to have a hit. Failure is an option which can in theory give more room for creativity.
On the other hand, one person's ostracism is another's right of association. It is just as wrong to force someone to work with a person they do not want to work with, as long as that reason is justifiable (i.e. not a protected class)
Where 'an entirely different biological impact' may just as well mean 'no impact at all': it may even turn out to prevent melanomas.

While everyone is busy losing themselves in radiation hysteria, where facts are only guessed at, the government is laughing their ass off, because everyone lost sight of the actual problem: that these machines are assumed to improve safety in the first place. The radiation scare is an enormous red herring that mainly harms the public perception of 'radiation', that wasn't too good to begin with, for all the wrong reasons.
