I used to be a market maker of stock options, amongst other things.

> It doesn't take 30 mins after the news breaks for stocks to move

When it comes to markets, test every assumption. In reality, information diffusion is unpredictable and heterogenous [1]. This is due to, in part, the "effects of limited attention in at least part of the population of investors in the market, interacting with some more sophisticated investors with better access to information processing technologies" [2].

> The derivative markets are almost exclusively dominated by hedge funds, banks, large investors

Individual stock (versus index) options are actively traded by individual investors [3]. Individual investors also actively trade futures [4].

There is no reply link on your comment, so I'll reply here.

Fake news was a huge issue before the election. People I know were discussing it daily.

Of course the Democratic Party talked about it after the election. What else would be expected? Many people who were paying attention were talking about it before that as well. You should read those articles I posted.

The Democratic Party and its candidate had problems, but that doesn't diminish the role of fake news.
It can be surprising though, I recall one of my children's school friends who although he was never very academic was always mild mannered and well behaved with us, there were other children in the school who were a much bigger problem. He is now in prison for murdering his girlfriend.
Didn't they say they would do this five years ago?

If by "very few people" you mean thousands of people, then sure.
Sure. But what are these alternatives? 1% of the population are psychopaths and no one knows how to make them not be so. What else can we do but put them away?

English, German, Irish, swedish descent = Christian, white population, all speaking English as a first language, all from similar cultures.

It’s way more diverse in Sweden. I lived in NYC, and have travelled a lot in Sweden. Nowadays, large Swedish cities are much more diverse.
A better title would be: 26% of violent crime convicts accountable for 63% of violent crime convictions.

In terms of the entire population, probably:

* 96% never convicted

* 3% convicted once

* 1% convicted as many times as the justice system allows until well into middle age (average of five times)

An interesting question is: How many of the 3% are released and take up normal life, and how many are not convicted again because their first offense was severe enough to warrant a long sentence? Edit: Unfortunately, the paper can't answer this question.
I'm curious what would have happened if China hadn't industrialized prior to robotics maturing and fully automating manufacturing. Can you leap from subsistence farming to software development without much infrastructure in between?
It's hardware, not software :-)

"The lightboard itself is made up of a heavy duty frame, a 3/8” sheet of low iron glass (commercial name starphire,) and a string of LEDs to wrap the edges of the glass to shoot light inward to make the neon markers pop on camera."

Vancouver climate is a lot more temperate than most places in the world. It rarely goes below zero, and during the few months of summer, it will rarely go above 27 C. Most houses don't even have AC so passive houses seem like a great idea.
A lot of the adaption was good but so many of the changes to the plot and characters were in the direction of pushing it into a cookie cutter Hollywood show that I eventually lost patience and didn't finish. Like the changes to Quellism, making the main character more of a chosen one, the soap opera-ish familial ties, and the mystical matrix warping powers.
the universe may be vast, but it's pretty empty.
Australia uses inflation-adjusted, zero-interest loans which are paid back like extra tax once your income is over a certain threshold. I think it’s a pretty great system, takes a lot of risk out of persuing tertiary education at much, much less of a cost than free tuition.

As long as it redistributes wealth from business and the wealthy it can work. I mean, it's not a revolutionary idea, people have been talking about taxing the rich and giving to the poor for as long as the rich and the poor and taxes have existed. But there's nothing about a taxation based redistribution UBI that makes it impossible.

Now, printing money wouldn't work for obvious reasons, but a surprising amount of UBI schemes are essentially that.
Childhood and adult.
Of course! With some defensive programming, e.g, the client ignoring unrecognized elements in the XML response while still reading the ones it does recognize, and not changing the API endpoint URLs, so long as the API output contains the values the client is looking for, there shouldn't be any reason why this stuff would break.

If the client used tilemaps versus vector data, I would expect the tilemap data to be out of date, but the directions would still be valid.
It could be other way around. Evolution invented imprecise and roundabout way of doing gradient descent.
I once wrote a static checker for Java. It found all breaking changes in APIs of all my dependencies. Any time functions were removed, parameters were removed, type signatures changed, it would catch them.

It would walk the maven dependency tree to find these, any time if found two versions of a library (say app depends on A and B, A depends on Guava 17, B depends on 18), it would log it as an resolvable issue.

On the project I tested it against, I remember it logging something like 250-1000 issues. I gave up. I'm not even sure where the code is now. Java is supposedly statically checked, but it lacks a real linker, as anyone who has ever seen a run time exception of "XXX is not a function" can tell you.

As far as Maven being "unpredictable", how it would resolve transitive dependency conflicts prior to 2.0 was undefined behaviour, and post 2.0 it is bizarre/lazy at best. It doesn't use the newest version, and doesn't flag major version conflicts. It just topologically sorts the graph and picks the highest dependency. The logic is bizarre. I have no idea if gradle handles it better, but they both face an unsolvable problem.

Shade is a pretty terrible work around. Auto-sandboxing conflicting dependencies in their own class loaders would be the most reasonable solution. As long as return values weren't passed between libraries.

Edit to add:

And this is not a theoretical problem either, as soon as you bring in a big dependency like Spring or Spark you are already 20+ levels deep in the tree, with dozens of these sorts of library conflicts, and hundreds of broken method signatures, just waiting to step on the wrong land-mine. (Not that I bet large ecosystem is any better)
Eh no. Letting go and accepting a node.js job. And hate it.
>They came from the same background, had the same advantages, and so on

Did they really though?

Thinking back to my childhood recently, I've come to almost exactly the opposite conclusion. There were some kids who I thought were just naturally shitty until I experienced enough of life to realize that they were the ones getting beaten up by their angry or alcoholic parents or being emotionally abused by a narcissistic family member.

These were all things that I saw the signs of going to their houses or at sports games, etc. as a kid, but it was so far outside of my frame of reference that I didn't understand the context for what was happening. That angry arm grab and wrench just because dad didn't like the choice of font on a book report? Not a sign of a healthy home life, especially if that was the way he behaved with an "outside observer" in the house.

It's all still anecdotal of course, with my small sample size and situation, but after going to a small school with the same ~25 kids (all from similar middle class households) for 9 years I can say that later success in life was strongly correlated to the ones that had supportive and non-traumatic home lives.
And to reiterate, I agree with that nuance and will do my best to apply it to future comments.
A lot of traders are just gambling, but there is also something of value being created.

Stocks are risky. People don't like risk. So the current price of a stock will always be less than its expected future value. Therefore the value of the stock will tend to go up.

So when you own a stock you're being paid for bearing the risk. This is a real service of value that you're providing for the world.
> There are many people who don't have that privilege either due to economic or time constraints.

This goes back to my early statement about school not teaching valuable skills. I told you I was a poor student, that was because I spent my time learning about computers instead of the curriculum I saw as wasteful of my time. You have to have the strength to make those types of decisions. Was it easy? Absolutely not, I paid all kinds of prices for doing such a thing. I stood by my convictions though, and thus have little sympathy for those who don't.

> You can't "work hard and study something of economic value" if you have to work two jobs to keep the lights on.

As mentioned above, if you're just starting to think about these things when you're old enough to work two jobs, you've already made bad decisions that are going to be very hard to reverse.

> Responses like this make it look like you're not engaging in good faith and simply want to argue against privilege because you've been told you should disagree with it, and that you're unwilling to learn what it actually is.

I'm arguing with you (neither of us are convincing each other of anything at this point) because you literally told me that my life was invalid and my philosophy as defined by my experiences are due to my own cognitive bias. You have no idea who I am yet feel totally comfortable saying such a thing.

If you take anything away from this it should be that if you're going to tell someone that their life experience is invalid, you're not going to convince them of anything. In fact they'll just entrench their positions. I'd eliminate that from your rhetorical bag of tricks if I were you.

And with that I'm done. We both learned nothing, and I'm still convinced that the core of your message is routed in smugness. Maybe you'll have better luck if you avoid making assumptions about people you've never met.
Good point. There's no sense in buying cheaper property if it costs more monthly to maintain.
I would say that C is comparable to Java in this regard, but Haskell breaks a lot as well. In Haskell, however, the community typically embraces breaking changes by standing up and fixing packages proactively; see, for example, Stackage and how they chase package maintainers once one of the package would break with a certain combination of other packages.
I have successfully compiled and used 30 year old Common Lisp code bases with minimal or no changes.
Manslaughter and murder are already criminalized, at least in the United States. Where do you live?
You probably also need to consider things like how often is physical discipline being used, and is it actual discipline or just an excuse for abuse.
I wish I could increase the insulation capabilities of my house. My house is literally stucco on the outside, a paper vapor barrier, and then it's the studs and drywall of my walls. I have no sheathing in between my studs and drywall, so I have massive air flow. I would literally have to rip down all my walls and add a layer of sheathing in order to stop air flow and add insulation, and would cost ~$50,000. Better to just turn on my furnace during the winter months and spend $300/month for 4 months a year.

For part of your portfolio yes but once you have a decent amount (when say your normal size of order is £2k) you want to start diversifying and playing on special sits and corporate actions.

An example from the UK electra private equity ELTA was on a massive discount activist investors came in and I made over twice my initial investment in two month - I would have busted my yearly allowance for dividend income just on that stock alone.
Not sure how it works in the US but in the UK you pay a stamp duty tax when your purchase a property, and then "council tax" on a monthly/annual basis which pays for municipal services like refuse, social care etc

Interestingly the amount of council tax you pay is tiered based on a valuation of the property in the 1990s.
> the indoor air temperature will be roughly equal to the outdoor air temperature

Your insulation could definitely be improved - I live in Scotland and when it's 0C inside it seems to equalise at about 10C simply from having humans in with cooking and lighting. That's still a bit uncomfortably cold so I run the heating, but without good insulation a lot of paid for heat would be escaping.
You don't.

It's written in simple language (and modern editions come with commentary updating it ) if you cant read that book then maybe you should not invest in shares at all.
This article is a little too glib in my opinion, preferring citations and statements to substance and explanations.

For a more cutting and insightful critique, watch Ali Rahimi's short talk at NIPS 2017 (where he was presenting for a paper that won the "Test of time" award, for standing out in value a decade after publication). The standing ovation he received at the end indicate that his comments resonated with a significant fraction of the attendees.

https://www.youtube.com/watch?v=Qi1Yry33TQE&feature=youtu.be...

Here's a teaser from the talk:

"How many of you have devised a deep neural net from scratch, architecture and all, and trained it from the ground up, and when it didn't work, felt bad about yourself, like you did something wrong? This happens to me about every three months, and let me tell you, I don't think it's you [...] I think it's gradient descent's fault. I'll illustrate..."

[Addendum]

Ben Recht and Ali Rahimi published an adendum to the talk, elaborating on the direction they envision -- http://www.argmin.net/2017/12/11/alchemy-addendum/

Ali also has a post taking a stab at organizing some puzzling basic observations about deep learning, and motivating that with analogous historical progress in optics -- http://www.argmin.net/2018/01/25/optics/

PS: The first 11 minutes, on the idea of using random features (the main idea in the research he presented) are also interesting.
Exactly. It might not sound like a big deal if life expectancy increases from 70-75. That's only a 7% increase!

But, when the retirement age is 65, you're retired for TWICE as long. That's a huge difference. Either pension contributions need to increase AT LEAST two-fold, benefits cut in half, or retirement age is always set at life-expectancy - 5 years.

Not to mention, somehow now 62 is the new 65. Making the problem almost 3-times as bad.
SubML (prototype) language
I'm cribbing part of what I wrote about the adaptation on Ars Technica. Spoilers follow, and I have no spoiler tags here.

Worst change from the book: Making Quellcrist Falconer into a technophobe and the personal love interest of long-ago Kovacs. In the book she's a famous dead[1] figure from history who a) admirably fought on the losing side of a rebellion and b) wrote a lot of quotable things. She's like a cross between William Wallace and Sun Tzu. Falconer thought that her followers could play the long game against unjust power, since human immortality made time irrelevant; she didn't argue that immortality itself was wrong. In the series she's just that tired stock character, the pseudo-wise reactionary who argues that there are Things Man Was Not Meant to Know.

In the book Kovacs seems to love Falconer's ideas, but she lived before him and they weren't a romantic item. He's not interested in personally trying to fight a rebellion against the whole Protectorate, either. He's just looking out for his own skin and a few people he cares about.

Making Rei into Kovacs's sister was unnecessary and again went directly against the tone of the original: it made Kovacs sad and conflicted instead of furious and calculating when it comes to permanently stopping her.

The series is visually gorgeous, and if you haven't come into the series with the expectation that the same ideas and noirish conventions will be maintained from the book (as I did), you may well enjoy it better for that.

[1] Yes, I read the later Woken Furies where Falconer seems to "come back" in a way, but an event from decades after Altered Carbon shouldn't have been shoehorned into the Altered Carbon adaptation this way. Or at least I thought it shouldn't have been.
Learning Haskell is one of those two weeks things that’s been on my interests list for a long time, but will likely stay there for awhile yet.

Though, if anyone has got any high-quality quick resources handy that’d be appreciated!
This is really great. I'd love to see a follow up covering other topics. Such as testing (with hedgehog), modeling SQL, etc. Or -- anything that helps open up the world to see how Haskell is a beautiful language to build on.
Then some months after, getting Ralph Brown's interrupt List, and finding that I can just call a specific interrupt in assembly to rename a file (and that's what the "C" library had implemented), Pascal was no longer limitation...

I really loved SWAG, which was basically a collection of 'how do I?'-questions with answers in the form of Pascal sample code. Interestingly enough, it seems that someone converted it into a website:

http://swag.delphidabbler.com

As a kid I went through and studied many of the SWAG snippets.

But haven't touched Pascal since 1999, and moved to C/C++ since then. I still miss the Units (.TPU files).

Also, the compile times and the debugger were awesome. The Turbo Pascal IDE was still better than many current environments. I stopped using Turbo Pascal when I switched to Linux more or less full-time (near the end of the nineties), though I did use FreePascal on Linux a bit.
That was my thought on reading the headline - it's somewhat skewed because you'd expect a similarly small percentage of the population to be responsible for _all_ violent crime convictions (as most people aren't violent offenders; the study notes 3.9% had at least one violent conviction).

Nevertheless, Cartpole is a trivial RL task which only requires a few neurons to solve, much less hundreds. Since they're training it in silico, I'm not sure what this demonstrates other than you can cudgel a vaguely spiking-like neural network into learning a simple task. It's not a C. elegans behavior.

I know this feeling all to well. My friends and I created a facebook group in 2005 that doesn't have a name- we managed to sneak some null characters through their filters. Our nameless group occasionally causes problems, including crashing the IOS Facebook app for about a year, but we didn't want to make a bug report because we thought they'd just give the group a name (ultimately one of our friends at Facebook filed a bug report and got it fixed without outing us).
To this day, how reliable are these kind of maps? I am not to familiar with open water maps and/or navigation but my experience from navigating close to shore tells me that charts not being precise can be quite devastating. Positive to the project as a whole, just curious. And maybe i just missed it on the page, but do they cross reference submissions with for example government funded mappings of the sea?
This article fails to mention any privacy risks to the volunteers.

GWAS have proven to be, at best, of little value. In fact, due to the unfortunate way that many researchers chase p-values, these analyses often result in misdirection.

What happens? Genome privacy is exchanged for weak science.
Possibly not options - you can identify potential value /arbitrage situations - higher risk than pure value to be Shure.

WARNING: Decreased Oxygen is a problem with well-sealed houses. I live in one.

You must have fresh air to avoid CO2 poisoning. If the outside air is a problem, then you either 1) give up on being passive and use conditioning of some form or you 2) begin the suffocation process (starts with poor concentration then moves to headaches).

This is one reason for NetZero as an alternative form of building. Even using a solar array with an HRV (Heat Recovery Ventilation) or ERV (Energy Recovery Ventilation) helps a lot if you don't want to run a full compressor-based system.
Weirdly enough I've been looking at homes in ruralish areas and contemplating buying one to live in and work remote for a few years. Might be able to do it cash, even in an old walled city, and it seems like it wouldn't be the worst way to learn German for myself and my infant.

Any comment?
