jbredecheon Amanda Gorman's “The Hill We Climb” (Full Text)

If someone made a poster with this poem, or excerpts from the poem, on it - I would buy one. Probably some copyright issues though.

jbredecheon Quantopian’s Community Services Are Closing

Hi, the lecture notebooks are in our research_public repo, at https://github.com/quantopian/research_public/tree/master/no...

Hopefully that helps! We'll be keeping these OSS projects online.

jbredecheon MixedName – Bilingual baby name finder

This is great.

Our kids are a quarter Finnish, a quarter Indian, a quarter French, and a quarter Chinese. I guess we'd need to run (4 choose 2) combinations here and work off of that list!

jbredecheon I almost sold Baremetrics for $5M

I couldn't agree more.

jbredecheon A Last Lecture by Dartmouth Professor Thomas Cormen

I had Cormen for my Algorithms class (using the CLRS textbook, of course) and he was great (iirc the problem sets were epically long, at least for me).

jbredecheon Collection of Jupyter notebooks for quantitative finance

Shameless plug, at Quantopian we have a bunch of materials (usually notebooks, sometimes also videos) covering introductory material in quant finance and Python: https://www.quantopian.com/lectures

jbredecheon Upgrading Messaging on Android in the U.S. with RCS

I have a Pixel 3XL on Google Fi. Every time I try to enable Chat Features on Messages, it just grays out on "Setting up ...". If I try too many times in a day, it locks me out for 24 hours.

If Google can't figure out how to make it work _on their own phone carrier_, I really do not have much hope for Android's messaging strategy.

jbredecheon Submit Your Claim in the Equifax Breach Settlement

If this breach affected 147M people (which is what I can find from various articles), and $700M was set aside (before attorney fees), and most claims will be $125, that's only ~4M people who will get $125.

Are they expecting very few people to file claims? Or what am I missing?

jbredecheon Can You Find the Bug in This Code?

Reminds me of https://github.com/twbs/bootstrap/issues/3057

jbredecheon New Dell XPS 13 developer edition now available

I literally just got a new Dell 9380 today, running Windows. My plan was to wipe and install Ubuntu. After I do that, will there be any functional differences between my laptop and this newly announced developer edition?

jbredecheon Behind the wheel of a Tesla Model 3: It’s a giant iPhone – for better and worse

https://electrek.co/2018/08/06/tesla-powered-audi-s5-convers...

This guy took an Audi S5 and put a model S powertrain and batteries in it. Even kept the quattro system!

jbredecheon Android P

Thank you, I was wondering why I didn't see the new nav!

jbredecheon Why Finnish babies sleep in cardboard boxes (2013)

Congrats! I think we used a pack-and-play sheet, which was too big and we just rolled the edges under.

jbredecheon Why Finnish babies sleep in cardboard boxes (2013)

There's a company that sells a version of the Finnish baby box, and we got one for our kid: http://www.babyboxco.com/ - everyone loved it. My wife is part Finnish, but we're in the US, so this was a good approximation.

jbredecheon Designing and Building Stockfighter, Our Programming Game

(I'm the CTO and cofounder of Quantopian)

I am incredibly excited to try my hand at Stockfighter. Hopefully some of the things I've learned over the last few years at Quantopian will be useful, but I expect I'll learn quite a few new things as well.

jbredecheon Robinhood: $0 commission stock brokerage

Check out Quantopian, where you can do just that in Python. Backtesting / paper simulation is free.

jbredecheon Google Search Terms predict market movements

(I work at Quantopian)

You can specify a commission model (https://www.quantopian.com/help#ide-commission) and a slippage model (https://www.quantopian.com/help#ide-slippage).

Right now, you have to enter parameters into one of our pre-made models, but soon (next week probably) you'll be able to write a custom model that uses whatever inputs you'd like to calculate commission and slippage.

jbredecheon Union Square gets 5,000% return on Tumblr

Congrats to Spark Capital as well. They're our lead investor at Quantopian and their intelligence and helpfulness have been everything we could have hoped for.

jbredecheon Yahoo Acquires Astrid

I recently started using Asana just for my personal to-do list, it's not bad and it's free. Haven't tried the mobile apps yet, but they look pretty good.

jbredecheon Show HN: How I Used Machine Learning to Optimize My Trading Algorithm

(disclaimer: I work for Quantopian)

I can't speak for the author of the algo, but from the algo, it looks like the relevant lines for your question are 34 (order(stock,indicator * context.bet_amount)) and 35 (log.info("%f shares of %s sold." %(context.bet_amount * indicator,stock)).

Our backtester (Zipline) will only order whole number of shares, obviously. If you pass it a fractional number, we take the floor: https://github.com/quantopian/zipline/blob/master/zipline/ge...

The log line you're seeing should probably flip the sign of the number of shares before logging. order(-63, sid(6109)) means sell 63 shares of security 6109. The log line is simply logging the negative value instead of the positive one. Users can log anything they want in their backtest.

As for the slow performance, apologies - being on HN has resulted in a lot of people running this algo and while we're scaling up new servers, it's taking a bit of time to distribute load.

thanks for using Quantopian!

[Edit - added source link to Zipline's order method]

jbredecheon MongoHQ releases SSD powered databases, autoscaling beta

You're also paying for backup, fulltime monitoring, and support - which, while not as nice as having a full time DB ops person on staff, is really nice. The MongoHQ guys have done seamless DB migrations for us and suggested architectural improvements, all with amazingly short response time. For now, we're happy paying them for that service.

jbredecheon Quantopian Brings Algorithmic Trading To The Masses
