drpancake··on The Space Shuttle’s Controversial Launch Abort Plan
I grew up in the English countryside a few miles away from a US airbase which was designated as one of the possible landing sites in the event of an aborted launch, due to it's long runway.

There was an American couple living in our village and the guy's job was to be on call during a shuttle launch. Suffice it to say he and his buddies spent most of their days playing poker.

drpancake··on BankAPI
I think it's excusable for a relatively niche B2B service where there's likely a huge variation in the size of their customers. Price discrimination is hard.

drpancake··on Frame.io: A GitHub for Video
Looks like a great idea. But good luck implementing those iOS-style blurring effects in a real browser.
drpancake··on What Happens When Digital Cities Are Abandoned?
I learned a lot from Cybertown back in the day. Hiring staff, advertising my block. I learned HTML and CSS so that I could style my block's message board and that eventually led to what I'm doing now, 14 years later.

Nobody knows you're twelve years old in a virtual world. I think at one point I was head of the city's night club.

drpancake··on Ask HN: Life advice for 25yo Web Dev, single, no debt, $30k/£20k savings
It sounds like you already know what you want to do.

I spent two years travelling the world while freelancing. I was building iOS apps remotely for companies in the UK. You'll be amazed how far the pound will take you in developing countries.

My advice is to spend six months in each location and try to really live there. Typical backpacking didn't work for me while also working.

Suggestions: Chiang Mai, Medellin, Bali, Berlin (cheap, but not the same kind of cheap as the others in this list)

My email is in my profile if you need any tips/ideas.

drpancake··on Just how much is that 2% really worth?
For a moment I thought this comment was just really good Markov chaining. What's that "LIPs not logging in" stuff about?
drpancake··on Venture Capitalist Tim Draper Wins Bitcoin Auction
Thanks.

> Do you provide any access to raw tick-by-tick event data or just bars?

The minimum granularity is 1-minute candles, where the latest candle becomes available at the close of each clock minute (e.g. 02:00:01 if we're fast enough).

> How do you secure your users' scripts so they don't worry about you stealing their ideas or front-running them?

There's certainly an element of trust here. There's a clause in our license agreement stating that we'll never access user strategies unless you ask us to, or it's needed for some kind of maintenance.

We don't trade on user strategies. That's not the model here.

>It might be useful to provide FX rates as a feed so users could come up with a synthetic price for non-USD pairs.

More generally I'll be adding a way to load in arbitrary data via HTTP requests within a strategy.

> For guys who want to work passive orders, an API where they can pass a dictionary of prices/sizes they're willing to buy/sell at into a goal seeking algorithm that handles canceling/placing individual orders might be a better match and more convenient.

These kinds of features (e.g. VWAP orders) are in the pipeline. There's certainly a need for tools like that.

Rather heavy reading, but this is probably what you're looking for: http://www.amazon.com/Trading-Exchanges-Market-Microstructur...

Most of the exchange APIs are pretty dreadful to work with. Shameless plug, but I've had to a build a unified library to deal with this at Tradewave[1] and it has been challenging.

Some of the newer, more professionally managed exchanges support FIX but those are at very low volumes right now.

drpancake··on The Next Chapter
What would you write in the same circumstances?
drpancake··on App.net State of the Union
Unless you count the wave of innovation coming out of cryptocurrencies, which are really just protocols for managing a blockchain. A decentralised Twitter could theoretically be built with this model.
drpancake··on Python for Finance
Essentially you can't sandbox CPython at the interpreter level, it's too introspective (I do it anyway though, just as a first level of defence). You need sandboxing at the OS level.

Happy to go into more details by email.

Shameless plug: my site Tradewave would be an ideal place to try some of these techniques out. We let you write automated trading algorithms for cryptocurrencies, in the browser, with Python.

drpancake··on Most of the Amazon SES IP blacklisted by SpamCannibal
Require a small fee to send an email, e.g. $0.01. Small enough not to matter for legitimate users, large enough to make spam unprofitable.

Bitcoin or some other cryptocurrency would be ideal for facilitating micro-transactions like this. Interestingly, the Hashcash concept was originally designed to fight spam, and later became one of the important ideas that made the invention of Bitcoin possible: http://en.wikipedia.org/wiki/Hashcash

drpancake··on Ethereum
Agree with you that it's not clear for newcomers.

I'm not affiliated, but basically Ethereum is an alternative cryptocurrency (or alt-coin) to Bitcoin with it's own separate mining algorithm and blockchain. The really interesting part is that it comes with a Python-like Turing-complete language, such that you can embed small scripts into transactions to define smart contracts.

This theoretically allows you to implement all kinds of applications in a distributed way with no central trusted authority. For example: DNS resolution, options, betting, distributed exchanges.

drpancake··on Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S
I could get behind that process, and I don't doubt that theirs is similarly rigorous. I guess the issue is that, in the long-term, how do we know that it's still being applied consistently and that there are no security holes.

This is a much wider and rather tricky issue (how do I know that my Bitcoin exchange is performing cold storage correctly and consistently?)

You could answer: more regulations and oversight. Doesn't solve the issue.

drpancake··on Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S
I'm sure there are strict security measures and a rigorous testing regime in place, but still the idea of some anonymous engineer being able to push an over-the-air update to my fast moving, two-ton lump of metal makes me a little nervous.

(Tin foil hat mode) Imagine the implications of some malicious third party gaining access to that process.

drpancake··on The Meteoric Rise of DigitalOcean
Wow, you guys actually redesigned your website!

(University of Bath CS grad here.)

drpancake··on Planes Landing in Beijing: Video from Space
UrtheCast are working on something similar. Their camera recently made it to the ISS and the next step is a spacewalk to install it.

drpancake··on MtGox's Bitcoin price drops to $260 (others at $600+)
I'll just jump in here and cheekily plug my service: http://tradewave.net

There are a lot of people building trading bots for cryptocurrencies, and it's pretty easy to get started by yourself. But not everyone has the chops or patience to do it well; for example gathering, aggregating and storing data across the various exchanges is a huge pain. So my site abstracts away that stuff.

You can't do real HFT with Bitcoin (and others) as the infrastructure just isn't there yet. The lowest I've heard is 15-30 second trades and even that's rare. Most people go for 1-2 hours.

drpancake··on Zynga Buys NaturalMotion For $527M
I'm exaggerating for comic effect. But I lived in SF for six months so I feel that I'm somewhat entitled to an opinion.

Yes, there are girls. I dated a few. But the ratio is pretty bad and most of them are tired of ubiquitous tech guys. I sometimes felt embarrassed to even mention that I work in tech. Maybe that's my problem.

drpancake··on Zynga Buys NaturalMotion For $527M
I'll try to explain my main reason.

Imagine you're a lumberjack. Now imagine that everywhere you go, every day, all you hear about is trees, chain saws and axes. Most of your friend's social lives seem to revolve completely around lumberjacking. And there are no girls.

I can completely understand a founder's choice to live there. As an employee, it's not my cup of tea.

drpancake··on Zynga Buys NaturalMotion For $527M
Those are really all of the options that you can enumerate for a developer not choosing to live in the Bay Area?

Honestly, every response you've written on this thread makes me cringe.

drpancake··on Zynga Buys NaturalMotion For $527M
"Honestly, I have a difficult time taking any developer who doesn't live here seriously, but that's a different discussion."

That sentence neatly encapsulates my main reasons for choosing to leave the Bay Area.

drpancake··on Should App.net Accept Bitcoin?
At this point I doubt it -- and the exchange rate fluctuates so wildly it would be heard to measure anyway. It seems to take macro scale events to move the price these days, e.g. the policy announcements by the Chinese government.
