Thinking of using this for back testing. The link is a great tutorial of using the AWS python API.

Great article about architecting high performance servers. It concentrates on http servers, but the general principles will apply to any high performance network engineering. Tackles concepts like file descriptor multiplexing techniques and the "Thundering Herd" problem. Sound like order flow to anyone?

I posted about the Michael-Scott queue before, but this site is excellent. A must read. Great compile-able code.

NYSE Flooded?!

I hear reports of this, but it's been redacted by many sources, so it might be bullshit.

Thanks Sandy.

Anyone hear anything about this? Looks interesting, but the site has very limited information at the moment.

The end-user agreement would have me thinking that it's trying to be a community for developing and sharing trading ideas. I am not sure what the community runners are getting out of it. Anyone have any more details?

Facebook Price

Just an update on FB. Since IPO the price has DROPPED to: ~20 USD (currently 19.05). So, obviously the P/E has gone down, right?

Wrong, Wrong, Wrong. We are at a lovely P/E of... 106.35! Which means earnings have dropped like mad.

Let's do a quick comparison:

FB - 4B revenue, Price $20 USD, P/E: 105, Market Cap: $40 B

Oh wait... I can't find anything to compare it to... there is NOTHING like FB. Does this justify the high price of the stock? No freaking way, so the question really is: "What price would you buy in at?"

$12 for me, just on the off chance they monetize somehow.

My current obsession is FlickChart.com, where it gives you two movies at a time and you pick a winner… slowly it starts to build what is your definitive top list of movies. It also builds the equally useful list of great movies you have never seen… The Shame List as I call it…

The longer you use it, the more you get ungodly match-ups like the above, that make me want to pace around the room for ten minutes to figure it out.

I went with 2001… trust me, it was hard.

This is pretty hilarious, just need a stock picking version of this. AAPL vs MSFT

Facebook Fizzle

With an estimated PE of 80, FB class A stock with a price of 38 dollars a share is ridiculous. Do a comparison of revenue vs stock price for almost any company. That said, I definitely thought the price would spike higher then it did the first day. There was even a sell off the day before (I thought people were liquidating so they could open FB positions the next day). Nope, missed it. I estimated that FB would close at 45 its first day: WRONG.

Makes me a little happier know that people aren't THAT stupid when investing. 38 a share is ridic.

So, free online courses are the rage today. This one is pretty cool. Great online videos, interactive quizes, ect. This course on Machine Learning comes out of Standford, and is of the quality you would expect.

Machine learning is generally applicable to quant trading, in that quant trading is mostly regression problems, which is a sub-category of machine learning.
