I am a software engineer, a mad scientist, a specialized generalist and a renaissance geek.

I grew up playing with test tubes and beakers, reading history and philosophy books, making model rockets, drawing just about everywhere, playing basketball, and tinkering with remote control cars and planes.

Currently, I am working at Ripple Labs, on Ripple: a distributed payment network that allows anyone to send money to anyone else, in any currency. It is based on the same principles as the Internet: free for everyone, accessible to anyone, owned by no one, and connecting the whole world on a shared network. You really should check it out - visit us at https://ripple.com.

I have worked as a software engineer for over fifteen years and although C++ is my favorite plaything, I have many others toys at my disposal and use them to do amazing things. I have developed just about everything – from shiny user interfaces to low-level kernel drivers. I've worked on servers that handle tens of thousands of users, caching software that accelerates hard drives using SSDs and encrypted distributed storage & backup systems.

My interests are diverse; beyond math-based currencies, they involve next-generation interactive software and input methods, cryptography, security, static software analysis, software protection, cloud storage and performance optimization.

You can find me on Twitter as @nbougalis or reach me by e-mail at nikb@bougalis.net.

Ah.... students... I'm so happy to not be teaching/grading anymore.

comment Sketching the graph of a function
Think about what it means for a function's first and second derivatives to be zero at certain points. You may find this and this article helpful.

comment Proving That The Product Of Two Different Odd Integers Is Odd
You can't prove that the integers are closed under multiplication? That's fresh.

comment Proving That The Product Of Two Different Odd Integers Is Odd
You can just state that Z is closed under multiplication and addition. If you want to prove that, check out the proof for addition and multiplication here.

comment What is the best base to use?
Slight note: there's nothing particularly special about base 8. Any base $m$ that is of the form $m = 2^n$ has a direct conversion to and from binary: simply group and substitute.

comment How to solve $x^{1/2}-x^{1/3} = 0$
I think that this can be trivially made "mathematically sound" and it's a nice way to show how carefully reading and understanding what the problem asks one to show is important before one starts writing.

comment Is every definite integral unique up to change of variable?
You're, of course, absolutely right. I think what I meant to say was that you cannot convert $I_1$ to either $I_2$ or $I_3$ and it just came out wrong. As I said, 1:00am. That's my excuse and I'm sticking to it!

comment Best way of introducing determinants in a linear algebra course
Yeah, the parallelogram is a classic example. I would also suggest you take a look at the Gilbert's Strang's 18.06 Linear Algebra course on OpenCourseware for ideas. He shows some great applications of linear algebra through the lectures.
