USA Murder rate 1948 : 5.9 vs 4.9 (2015 aka now) I don't know about you but I would call Murder a rather extreme unethical behavior. https://en.wikipedia.org/wiki/List_of_countries_by_intention...

Now, compare with say France a very secular and minimally religious country and their murder rate is 1.31 (Though not 100% apples to apples this extends across many other similar statistics.) : http://www.nationmaster.com/country-info/compare/France/Unit...

Surprisingly China and Japan perhaps the most atheist countries out there with significantly different economic situations also have lower murder rates than France. (Though again not apples to apples statistics.)

PS: I often hear about morality religion links but only see a few meaningless connections like church attendance and divorce rates.
I'd definitely love to see stats or sources for this!
Whys should other companies offer better terms? There is enough unqualified workers everywhere so there is no need to compete for them.
> Passive investing using index funds is definitely not sexy, but it gets the job done.

Only if you have a significant amount of capital to play with. People looking into active trading are doing it because they don't have the necessary capital to make passive investing meaningful; they're looking for much much larger returns that you can get from an index fund, which necessarily comes with more risk. Traders are gamblers.
That was actually true. Jobs was paid in stock options, perks (including a Gulfstream V jet), and the increasing value of the Apple stock he got in the NeXT acquisition, but no salary.

Yep, the smallest atom, hydrogen, weights ~ 6 * 10^-23 of a gram [1] (that's 0.000... some 23 zeroes ... and corresponds to 1 "atomic unit"), and other atoms weight just tens or hundreds times more (so still in same ballpark).

The bases (the letters in the four letter DNA alphabet), mostly built up of light atoms, weigh each just a bit over 100 of such tiny parts of a gram (atomic units, or g/mol, to be exact) [2] [3] [4] [5].

They appear in pairs, but still, even given that a pair weighs around 300 * 6 * 10^-23 g, you can fit quite a few of such base pairs in a few grams. Ca 3.3×10^20 / g, or ~ 330 000 000 000 000 000 000, given this rough esti-calculation.

> Stop losses are at -70% or so.

Am I reading that right, you lose one trade you lose 70% of your capital? Sounds like a very very dangerous strategy with a near 100% certainty of blowing up the account. The optimal trade size for equity growth (which is itself hugely risky) is vastly smaller than that.

>Am I implicitly creating goroutines by using channels or am I simply creating a buffer?

A channel is just a thread-safe queue. An unbuffered channel blocks until something else receives the sent value. A buffered channel allows n sends until it blocks. Using a channel will never create a new goroutine, its just a way send data. You can use a select statment to wait on sending or reciving from multiple channels or to send or get without being blocked by a full or empty channel.

In C you could put together a RW mutex, condition and a linked list or array and have the same thing pretty much.... If you want to create a goroutine you need to invoke "go X".

Out of curiosity, do you know C/C++ or Java?

I have a copy of an old edition of that book on my bookshelf, published 2003. I haven't gotten around to read it yet. I bought it because the cover stood out to me at a flea-market, and also because it was one of only a few books there which were about computers and I wanted to pick up some computer books for cheap.

There are serving politicians from a variety of legislatures around the world who have accounts on HN and have made comments in the past.

I haven't seen one from the US, however.
Return free filing, the ultimate in tax simplification, is also opposed by the politicians who claim to be for tax simplification. You could set up a progressive tax code in a way that requires computing non-trivial integrals, but as long as the math is done by the IRS, it would still be simpler than what we have today.
You are oversimplifying and overcomplicating at the same time. If it was an easy/obvious zero-sum game, we'd not have people going into finance at all.

MIT does not teach "HFT", those "MIT PHD Quants" are just as untrained in finance as you are. The rest is math, something that requires time to study but not necessarily a certificate. And creativity. I've only seen a single HFT-algo that made me say "wow, that's creative"; all others were just straight implementations of finance "wisdom".

UPS trucks carry lots of packages so that they don't have to reload at the warehouse mid-day. That's not really a concern for Walmart employees, since they wouldn't be making any special trips to the store to load up on packages.

True, UPS has the advantage of denser delivery routes. But I'm sure Walmart has done the analysis and determined that they can deliver (some) packages more cost-efficiently than UPS despite this. Same with Amazon, which has been hiring their own couriers in some areas.
> technical analysis which is basically patterns proven to repeat in markets for a variety of fundamental reasons

Technical analysis is merely another name for hindsight bias. Those patterns only look like they repeat in hindsight because you're ignoring all the failed patterns that setup right but failed to play out and thus don't look like the pattern in hindsight.

Technical analysis is exactly like astrology and is in no way grounded in science. Quantitative analysis is based in the scientific process, technical analysis is superstition created by visual traders who think they see patterns but fail to understand biases. You are confusing the two, technical analysis is a pattern library of nonsense like "head and shoulders" or "dead cat bounce" based purely on visual patterns in price data that only "appear" to repeat due to hindsight bias. It is in no way remotely scientific.

I've spend thousands of hours testing trading patterns in Forex, they're all nonsense that lose as much as they win over any decent sample size which equates to random.

Edit: to the guy below, You should ask for sources that back up the claims that it does work. You won't find any, it's trader superstition, not science. You don't have to prove things don't work; you have to prove they do. At least if you want to call it based in science. However, the field of quantitative analysis itself is proof technical analysis doesn't work; it's what happened with people who actually knew math got into trading and discovered the technical analysis superstition that visual traders who lack math skills made up.

Well ... it seems you might be right. Another estimation states:

"Capable of storing 215 petabytes (215 million gigabytes) in a single gram of DNA, the system could, in principle, store every bit of datum ever recorded by humans in a container about the size and weight of a couple of pickup trucks."

Not sure what they base it on though. Perhaps we'll have to do a more proper calculation ourselves ...
It is also important to say that the trend of making you most likely criminal "because you use cash" will continue.

It is already known restaurants owners are getting in trouble for small deposits. Its not even $10,000 or $9,000 you deposit.. if you happen to make daily deposits of even few hundred dollars you are guilty of "structuring" aka smurfing.

Another thing is to make sure you can track back your physical hoard of cash. My friend's father is in deep explanations with FBI (and over $50,000 in attorney fees) because when his wife passed away he took all the money they hoard at home under floor and put it in the bank. Some $600,000 of it. IRS didn't like that and proving you had a job all your life and you paid taxes on Over $10,000,000 in income did not stop the case.

So, I got semi-seriously interested in this around the end of last year.

My takeaway is: it's not about implementing a couple of trading strategies. It's about implementing a pipeline that rapidly allows you to test what-if scenarios.

I might have like 10 ideas a day for strategies. How many of those can I rigorously validate per week? What about variations? I.e. tuning various hyper-parameters? Combinations?

How quickly can I recombine data from various sources into exactly the layout I need to train and test this or that strat?

Me:

1) Build some simple forecasting NNs.

2) Realize I need to be able to generate and test ideas waaay faster. Start working on infrastructure.

3) Get impatient -- get some "bright" ideas, do some manual trading.

4) Make some money on the first day, lose double that on the next two days.

5) Decide to ban myself from manual trading as obviously I'm an addict. Resolve to only do algorithmic trading.

6) Back to coding infrastructure. Get bored ... do some manual trades.

7) After losing around $20k, stop the trading madness, and go back to buying and holding great tech companies.

8) Enjoy my 25% returns.
Quants don't usually have CFAs. A phD in physics is more common to see. CFAs help you working in a real financial environment where you need to be aware of a lot of stuff. If you want to day trade at home, it's close to useless. Please nobody gets a CFA if what you want to do is learning day trading.
This is much better than Uber and the likes which don't make you employees and therefore don't cover anything other than the straight hourly payment.

Unlike Uber, whose greatest contribution yet is allowing me to use an app to hail a black cab instead of a phone, this is actually a smart innovation that leverages the fact that employees actually drive home.

If it was a startup I bet a bunch of critical comments would have been supportive instead.
The same happened in Spain, first time I saw someone doing a payment by mobile was at a bus-stop, as if it was normal he paid his electricity bill. It was the result of a collaboration between Telefonica and one or more banks, I forgot what it was called.

Way ahead of the rest of Europe, this probably was early 2000 or 2001.
what kind of DB was the reporting database if you don't mind me asking? Seems like translating the data into Google Sheets is unnecessary if you're just trying to graph/chart it, although as I say that I'm realizing there may not be a tool that could just graph it directly that's easy enough to use/cheap enough.
Aren't JPEG's lossy? I can't think of a reliable and performant way of retrieving data from a JPEG.

Hah, no that's a typo, sorry my mind was a bit scattered in this thread. I meant to type that stop losses are at -15% or so (of the position, not the portfolio).

There is a separate risk management metric in play that automatically closes positions and pauses the strategy after a specific number of losses in a row, or after the strategy's capital allocation drops below a certain percentage (whichever comes first).

The other metrics are as stated.
We'll use that above. Thanks!

I appreciate your insight. One thing I might add to bolster my reason for wanting compensation is that the prototype is critical to their business and without it they will be set back several months which they cannot afford. Furthermore, their vesting schedule gives them the potential to work me to death in the first year and then take everything I've built (past and future) and show me the door before anything vests.

On the other hand, if I walk, I might have wasted a few months time but at least I will have comparable salary in a stable job. 3% in early seed rounds just seemed pathetic to me when my role would be vital to the companies ability to grow.

Last year a friend of mine finished work on "Skips Stones for Fudge" (mentioned at the end of the article). This is a documentary about competitive stone skipping. The world record was broken a couple times during filming. Some of the same guys in this article are featured in the film.

It's really fun to see people who take things like this to the limit. The film is worth a watch.

On compression yes but you can craft a jpeg image which has exactly the pixel data you need. It will fail if someone recompresses your image, but that would be unlikely
Disagree. I think Trump is saying, "You'd better be willing to pay for your own defense. If you won't, don't expect us to bail you out," precisely because Trump feels like NATO nations keep expecting America to pay for a strong military so that they don't have to. So he threatens them into a new mindset, where they have to beef up their military because they can't count on America riding in to their rescue any more.

You want to say it's going to backfire? Fine; you're quite likely right. You want to say it's risky? Shortsighted? Yes, and yes. But I don't buy that it's because Trump is in Putin's pocket.

Oh... HUGE difference. What percentage of the portfolio is the position? How long have you run this strategy; I ask because those are huge returns that indicate to me you're taking huge risk which can work short term but nearly always wipes you out over a sufficient amount of time.

Having to get rid of toxins is a rather interesting problem to have when making plastic foam. Saxitoxin, a toxin produced by some algal blooms, is amazingly dangerous with LD50s of 5.7 μg/kg[0]. It's even been estimated that 50 μg of it absorbed through open wounds would be enough to kill a person.

All in all, this is probably a small issue. Potential barriers to scaling are that algal blooms form randomly, the need for solar drying, and whether the material actually holds up to use as well as the current foams we use. I'd even question that this is more sustainable than regular foam production until they do a full life cycle analysis of the process.

While it is true that CNTK can use CuDNN LSTM, if the recurrence does not fall into the 4 recurrences that CuDNN supports, CNTK is still much faster. The simplest way to verify this is to take a Keras script that uses whatever recurrent network you want and run it (on a GPU) with Tensorflow backend and with CNTK backend. Some anecdotal evidence suggest an easy 3x speedup.
