Before I got my pitchfork ready, I decided to test with a comment on YouTube: https://www.youtube.com/watch?v=ufrR98sR7XY&lc=UgyRmEKscwt_U... (scroll down to highlighted comment).

daveytea··on MakerDAO gets stress tested as ETH price plummets
> There's no way to instantly convert the stablecoin back into the collateral asset, you have to find someone with a CDP who is willing to buy the stablecoin from you.

This is incorrect and actually doesn't make sense. An important part of DeFi are DEXes (decentralised exchanges) such as Uniswap and Kyber. There is a liquidity pool where you can instantly buy/sell assets. There is no 'waiting' to find someone (i.e. no problems with coincidence of wants). You definitely do not need to find someone with a CDP. You can hold DAI without opening a CDP. Contracts can hold DAI (as DEXes do).

> Similarly, there's no way to unlock your collateralized asset, you have to find someone who is willing to sell you the stablecoin in order to open up your vault and get your eth out.

Also incorrect. You need to pay back the debt of your CDP with DAI. You can do this easily by buying DAI on a DEX, paying back the debt, then releasing your collateral. Some services exist to do this in 1 transaction, so you don't need to actually 'buy' any other asset. You just send the transaction to a contract and they take care of the details.

The DeFi, specifically the Ethereum space, has moved very quickly in a short amount of time, so there are a lot of new concepts and instruments out there. I think a more traditional finance person will have trouble understanding it all as in some cases, there are no analogies to the traditional finance system (e.g. flashloans).

Open source sounds great! Please post back here when its available as I really like your service.

This is great and potentially solves a challenge i'm having right now working with geth. However, I'm not comfortable sending private keys to your API end point. Do you guys have a solution to solve this concern? I'm sure others would probably feel the same...

daveytea··on Deep Text Correcter
This is really cool. If you're looking for more datasets to train your model, here are a few relevant ones: - https://archive.org/details/stackexchange - http://trec.nist.gov/data/qamain.html - http://opus.lingfil.uu.se/OpenSubtitles2016.php - http://corpus.byu.edu/full-text/wikipedia.asp OR https://en.wikipedia.org/wiki/Wikipedia:Database_download#En... - http://opus.lingfil.uu.se/

I'd love to see how good your model gets.

daveytea··on Show HN: DeepRhyme (D-Prime) – Generating dope rhymes with machine learning
This is great. Well done to OP! I've been considering creating something like this in the future as well.

You mentioned that you used the lyrics from 50,000 rap songs. Did you have any filters for quality or certain sub-genres? What era were the rap songs from? Maybe the 'quality' would be higher if the data set was narrowed to what you consider quality hip hop lyrics.

Also from your post: "You can see that D-Prime does internally rhyme to a small extent, but making the model better in this regard seemed like it was going to be tough, and I didn’t pursue it." What were your main challenges to improving/pursing better internal rhyme schemes?

daveytea··on Bitcoin Developer Guide
For 'm of n transactions', you can choose to have multiple signatures required to execute a 'contract'. This can be 2 out of 3 signatures, or 10 out of 100 signatures, what ever you decide to set.

This is as good (and better) than current escrow services as it is decentralised, between the contracting parties only, and can have very fine grained conditional statements or scenarios before a 'contract' is executed.

In the example you gave, the escrow could consists of you, me, and a computer program. You sign to say you've sent it, the computer program I used to open it signs it, and I also sign it when i view it. So in this scenario, you could get paid when 2/3 parties have signed, or have a staggered payment structure of 50% when 2 have signed, then the other 50% when the remaining person has signed. This would be escrow, but escrow based on the quality of a digital good.

Hope that helps :)

daveytea··on A Bitcoin Battle Is Brewing
Bitcoin is not anonymous and not meant to be. It never will be and shouldn't be to gain widespread adoption.

For the average person, I can list a few reasons: - near immediate transfer of money across international borders - close to zero fees or greatly reduced fees when transferring money internationally - safe and secure store of value (for the unbanked)

Then there are the future killer apps that will be created - tipping on the internet (changeTip / Coinbase) - programatic money - smart contracts - pure play digital banking - ??

It's hard to see how bitcoin could apply to the general public sitting at your computer in a first world country. But keep in mind there are nearly 5 billion unbanked or unserved people in the world where bitcoin (or similar) will change their life.

TL;DR: "We conclude that pooled results from in vitro and in vivo studies suggest that mobile phone exposure negatively affects sperm quality." They're not sure if it's due to RF or heat from the device.

Well, that's where some of our magic comes in :) I'll see if one of our techies can shed some more light on it for you.

We don't have plans immediately.

daveytea··on App.io Ads – Your game becomes the mobile ad, with try-before-install
Super responsive. :)

It's a streaming tech, but we can target on the ad network level (wifi/4g/3g/etc). We only run ads on devices where we know they'll have a great user experience, since we hate crappy ads as well!

daveytea··on App.io Ads – Your game becomes the mobile ad, with try-before-install
Our economics work out pretty well ;)

Good point on having more info. What we've found is that developers will want to get into the nitty gritty details, whereas ads people will want easy to digest info about how it will benefit them.

If you're keen to find out more, we have some pretty good documentation: http://docs.app.io/

daveytea··on App.io Ads – Your game becomes the mobile ad, with try-before-install
Thanks! We've worked hard on this so it's great to hear other ad players like what we're doing. Maybe there's a way we can work together.

Feel free to reach out to me (david@app.io) if you want to chat :)

daveytea··on Ask HN: As a European, how do I get to Silicon Valley?
Get a visa to come here for an internship, build your networks & explore, then look for a 'serious' job after this. There are many places to look for jobs.. AngelList is probably the easiest place at the moment. You can also find wage information there.

Rent really depends on where you are located. SOMA could be minimum $2k+/month for studio. Mission area could be cheaper. SV probably has similar prices to SF.

Look for housing on airbnb/craigslist/walking around... really depends on what type (long term, short term, etc). There are also a few hacker houses around that you could probably stay at.
