Exactly my thoughts. He comes across as the ideal candidate for further study. No doubt, if he's as capable as he makes out, he'd be able to get a PhD scholarship, and spend all day doing what he wants do to. Granted, there is still a lot o

I'd assume the JPEG can have some embedded colour profile. This profile specifies a transform between the JPEG's 24bit colour space into the monitor's 30bit colour space. For example, consider two JPEGs with embedded colour profiles. "Red"

From another comment: > pg says in a later tweet reply [1] that it is 37 out of 511. So ycombinator's v-index is likely 37.

In academia there's an author metric called the H-index > A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np − h) papers have no more than h citations each. I wonder if you could apply th

I feel that Tesla's success with the Model S is due to its fairly conventional shape. It looks like an "ordinary" car. I'm not sure if the design aspects of this VW are due to improved aerodynamics, or a desire to make something look "futur

"IF YOU'RE an engineer in Silicon Valley, you have no incentive to read The Economist," Wow, "unnamed tech entrepreneur", I strongly disagree. I have yet to find a news source that competes with the Economist. Just reading a single issue co

Awesome. Is there a video recording of your presentation anywhere online? What strategies did you use to combat the lack of stack traces, especially in production? I was happy to see that you are fellow Brisbanites. I'm a bit out of the "lo

Interesting. If you replaced R(t) with a stochastic process, perhaps with a time-dependent drift, you could incorporate a degree of uncertainty into your revenue predictions. You would then be able to solve for the optimal burn rate B(t) us

I've recently used Prefinery ( https://www.prefinery.com/ ) to handle a Beta launch. Highly recommended. Out-of-the-box support for "viral" social referrals, exporting to MailChimp, webhooks to notify of new sign-ups. Nice minimalist bootst

Well, mathematically you're constructing a synthetic put. You're giving up the potential upside in the stock while keeping all the downside risk. The "premium" or lotto ticket you're selling is your compensation for foregoing any upside pas

Here's a list I wrote up for a friend when he asked for a few "non mathematically hardcore" finance books to read. http://brotchie.github.io/favourite-finance-books.html It overlaps somewhat with the OP's list, but I have a tiny bit of co

Nice website. However, it is not-at-all obvious that I need to scroll downwards. Perhaps, after landing, if the user doesn't scroll down within 2-4 seconds fade-in-and-out a arrow, or some kind of indicator to scroll? edit: Looks fine on 13

On a similar note, a while back I wrote a bi-directional, fan-out adapter between the Interactive Brokers API and ZeroMQ. https://github.com/brotchie/ib-zmq The annoying thing about the IB API is that there's no framing; that is, you can'

Really nice idea, I usually have to resort to some Javascript hackery to do this kind of thing (or BeautifulSoup). One click is awesome. A simple spoken script over the tutorial video by a voice actor would add significant credibility. Th

Nice! I have a "pod" in the Cocoa Pods repository and the documentation has been reproduced faithfully! I like how you pull the github README to use at the documentation landing page.

Nice, I didn't realise the relationship between rotations and the matrix square root: multiplying a vector by the sqrt of the pi/2 rotation matrix rotates it by pi/4!

I totally agree with this sentiment. My parents would always attempt to answer any question, however absurd: What's this made of? wood. What's wood made of? Carbon, Hydrogen, and Oxygen. What's Carbon made of? Protons and Neutrons. What's a

Incorporating a company is relatively cheap ($450AUD) and the last time I did it, it was done <10 minutes. All you need to do is scan and email through some identification, nominate the directors, and set the allocation of shares. Most

Nice! I've always been fascinated by tools and techniques that reduce the burden of solving complicated PDEs. After deriving, by hand, the finite difference matrix for a two-dimensional 2nd order PDE with varied boundary conditions I though

Life: Quitting a stable software job to do a PhD in Finance. The additional technical skills (Writing, Mathematics, Finance, Law, Accounting) and interpersonal skills (Networking, Explaining complex topics) I've gained have been invaluable.
