Or C++ at any point in it's history. I guess it's the burden of being multi-paradigm.

Edit: Looks like zak_mc_kracken beat me to it. Which I think just makes the point even more obvious

I would like to read this book but the O'Reilly website eBook + Print combo deal is not available until next year.. Does anyone know how I can order both and get the early access ebook now and then the print book when it's ready?

That would be awesome, I'm using Scala and I would like to incorporate more scalaz into my programming but I have yet to find information convincing me how to go from math concept to implemented functional design pattern.

I worked at a hedge fund at the start of my career, though it was somewhat atypical as it was a very new fund and had more of a startup environment than a well established hedge fund. The work was a fantastic split between analysis and building new software to run the fund.

But to your point, the CTO of the fund was a pure math phd who got into finance/coding when his advisors asked "Ok so now how are you going to make money". which is common for most of the heavy duty quants I know.

I wanted to give some recommendations before I hijacked your thread with my own question but I was going to suggest What is Mathematics, How to Prove it and Naive Set Theory which have already have been mentioned.

I'm actually in a related situation in which I'm competent in analysis (bachelors in physics) but I struggle with all the category theory inspired design patterns in functional programming.

Every book/article I've tried to read is either far too mathematical and so is disconnected from programming or is too close to programming and lacking in general foundations (ie: a monad is a burrito).

I would greatly appreciate any suggestions!

I would totally buy that book for my coffee table

Is that the same method as fluorescent lighting?

Does anyone else have an opinion on this book, I dismissed it at first but this has me reconsidering.

For my high school's CS class final project, we made a street brawler using doom characters. All the doom art was captured via opening a game and using print screen, then hoping the sprite was in the right position.

In retrospect, our sprites had their own lofi charm but yea, I never thought to just open up the WAD files.

This is the link I bookmarked for later so not 100% sure it works:

Wow I would love a Jane Street shirt

Very cool, it would be nice if the animations looped though!

Ah great, I uncommented the line but I didn't have the fonts installed.

The (left,right)_seperators for me are | instead of the cool looking arrows. How do I enable these?

Awesome project! Any timeline on vim support?

Kixer - Austin, TX - Remote

TL;DR: Mobile web ad platform optimized through machine learning and powered by Apache Scala

Full Stack Engineer

* Polyglots and generalists preferred

* ML background a plus

* Buzzwords: Spark, Scala, Kafka, AWS, PHP, Angular, Mongo plus many more!

Kixer is a funded ad platform that helps app developers get more app installs through the use of targeted ads. It's a giant optimization feedback loop and has to be very fast as well. Small engineering team in Austin although remote is possible.

More information here: http://kixer.com/jobs/full-stack-engineer/

Mention HN!

I'm going to go way out on a limb here but also I would think that 4chan would be more likely to contain the type of smart person willing to put in many hours into a problem with very little real expectation of an end goal/reward. At least more so than the other communities.

Agreed, as someone who worked in HFT and thus has a positive bias towards it, I found Dark Pools to be an extremely informative and factual historical account of the industry even if the author's opinions disagree with mine.

Flash Boys however I can't even get through because the author backs an extremist negative position with completely incorrect facts. I fill with seething rage every time I realize how much more public exposure Flash Boys gets.

Andddd... whoops.

That's not really true per se. That's the chart of USD/BTC so the inverse of BTC/USD which has dropped significantly in the past few days so of course the inverse has shown an increase.

For a more accurate picture of the dollar I track the UUP ETF which pegs it's value to the dollars exchange rate over a basket of currencies. (Which btw has been on a steady downtrend in the past 6 months, definitely not doubling everyday)

Almost same exact story although I never got into Doom modding but did make my own games in high school because of doom. Actually reading "Masters of Doom" truly planted the seed for my entrepreneurial spirit, the first time I realized "I can get good at something and create something just for me. I can value just from sheer will"

I'm a bit late to the conversation but I agree with you and just wanted to add my quick two cents.

I used to work in algorithmic trading (the kind which aims build consistent viable portfolios, not the HFT arms race).

This of course relies heavily on building your model, which can be anything from some simple linear regressions to more advanced techniques more commonly associated with the buzz word of machine learning, this applies to all predictive methods. You begin searching the training data to find optimal model parameters and then verifying performance on the validation set. The number ONE mistake I saw most was that when you get bad results on the CV set, going back to step 1.5 instead of just throwing the whole model out. To take your same core idea, tweak it slightly, add/remove a few parameters and restart the process. Unfortunately doing this enough times and your CV set starts to become the training set. Thus leaving your true validation set the day you turn it on live in production with real money.

It's never a good feeling to see your positively skewed returns in your training, testing and "CV" set morph into essentially a mean zero random distribution in production. This was quite an important lesson to learn for me.

I haven't put up the source because it's pretty coupled with the hardware, that sign in particular is a BetaBrite. I used a Raspberry Pi and a ruby script to drive it. I was able to find a ruby library for the sign.

Somewhat unrelated, but I made a bitcoin LED ticker, here's a link to an early testing video: https://www.youtube.com/watch?v=qxRIeb22QGI

I later added some other price information (gold, usd, s&p500)

I completely agree with you. Playing with Mathematica in high school was the only reason I had any interest in math (ended up studying physics).

I also agree FOSS is important but to 15 year old me, the fluid and polished experience of Mathematica was far more important to me than FOSS.

I don't know of your exact needs but cluster management is always a pain have you thought more of a "DBaaS" type platform like TempoDB (https://tempo-db.com/)

I don't personally use any of these products but I know Northwestern University did a very similar project with their football team. They had success with the normal consumer level product (either the flex or up, don't remember which)

This is the LinkedIn profile described in released report. I had to check because we got the same major at the same university within 5 years of each other.

I set this up for use at my previous firm and it was extremely difficult and that was 2 years ago (so version 1 or 2 I think).

It was great once it finally was up and running but I'd only recommend it if you have a legitimate intellectual property concern and can't use github enterprise.

It is my professional dream goal to submit to SIGBOVIK
