I cofounded a social discovery company a while back, so have thought through similar issues. Consider a dating site -- at the minimum, it must laboriously onboard a number of users at each location. Your site faces a much more difficult cha

I had a required 7:30am class my freshman year. The professor started each class by rapping her ruler on the front table to startle everyone. Then, she individually called out people who nodded off. What a nightmare.

Many top people have been very self-motivated at some point in their lives. When you experience this, you can sit down and work on problems in flow day after day without fatigue -- even when the going is rough. It feels like solving a puzzl

It's all about who to trust. Science sometimes gets it wrong for a while, as do some scientists. However, I would trust expert academic financiers over someone who by luck happened to have a good year with his or her stock picks.

This attitude of not trusting experts and not trusting statistics unfortunately permeates from the political arena into science. The belief that all statistics are not to be trusted is a clear danger to our society. Not trusting climate sci

Implying that most experts have agendas that supersede the truth is outrageous and frankly dangerous. Saying we should just give up on using data to make predictions is ludicrous -- even if it hasn't worked before in some situations. W

The linked paper discusses using its enormously parallel nature to quickly solve large instances of NP-complete problems. Aside from this, imagine taking a "smart" medication that uses biological computation to determine exactly w

As part of a data science/machine learning course, I have taught many, many beginning students how to use Python 2 and (starting a year ago) Python 3. The reality is that given what beginning programmers learn, they hardly notice the d

As part of a computer engineering degree, I made a fairly complex CPU (and also a GPU) on an FPGA. Also made a CPU out of NAND gates.

I got a 1080 working with VS 2015 (via the CUDA 8 beta). However, I strongly recommend using VS 2013. Frustratingly, CUDA VS 2015 support does not extend to the latest Visual Studio update level. So, to use CUDA I had to forgo the latest ve

This reads very presumptuously. The FBI stated she was reckless yet did nothing illegal. Reckless neither implies bad nor corrupt.

From what I've experienced, most people don't have a "passion" coming out of high school. They figure they're pretty good at math, enjoy computers, and CS pays well, so they might as well major in that. So, it'

The cornerstone of the scientific method is "hypothesis testing via experiments". Data scientists typically skip the experiments and make models based on pre-existing data. So, I am skeptical of calling it a science.

low and high are assumed to be positive and at most 2^31 - 1. So, there is a zeroed high bit in each which, for a signed int, is reserved to indicate negation. When low and hi are summed together, the high bit of the result might be set. Fo

Interestingly, assignment inside conditionals is usually avoided because it is easy to accidentally do an assignment (=) rather than a comparison (==). Note that for multiple assignment this mistake can no longer happen: irb(main): a, b
