Don't call me a '5:01er'

Don’t call me a ‘5:01er’, For one thing, I leave at 4. If that bothers you, feel free to stop by my office any day at 7am and we’ll talk about it.

What it means to be a good manager

Everything I have to say about the differences between a good manager and a bad one can be summed up with this simple distinction: “A bad manager makes you work, a good manager lets you work.”

Why can't a CEO be a family man?

Last August, Max Schireson, the CEO of MongoDB, announced his resignation in a refreshingly honest blog post explaining that he wanted to spend more time with his family. Despite the fact that Schireson’s decision appears at face value to be the obviously correct choice, his announcement was quickly propagated from tech circles to the mainstream media, and served to rekindle various ongoing debates over work-life balance, gender equity, competitiveness in the global economy, and the role of class privilege in the top echelon of corporate power structures. While it’s a little unfair to Mr. Schireson to overload what is essentially a private decision with a heap of weighty social issues, as a public figure he is surely used to such attention and since these are very important issues, it is still valid to use his example to discuss them in these contexts.

Blog workflow - jekyll, s3, bootstrap

In this post I will describe the workflow I used to generate this blog.

Release of mlelr 1.0

Today I am extremely happy to announce the release of version 1.0 of mlelr (pronounced ‘mealer’, of course), a C program for Maximum Likelihood Estimation of Logistic Regression Models that has been in sporadic development for over 12 years. For everything you need to know, read this guided tour of mlelr which accompanies the source code.

Big data is a terrible term

The term ‘big data’ sounds infantile, like ‘My Computer’. It should hurt the ears of anyone with any appreciation of Style. This is a buzzword that deserves to be cast into the dustbin of discarded buzzwords as quickly as we can possibly do so. On the way, I’d like us all to consider that maybe ‘medium data’ isn’t getting all the attention that it deserves.

Requiem for a Meeting

Meetings are the uncomfortable fact of corporate life that we all love to hate. They are so often maligned because they are perceived to be a waste of time—nothing seems to get accomplished, they run too long, the right people are not present, there is no clear agenda, and most importantly, meetings interrupt the normal flow of work for everyone involved. It does not have to be like this. If executed with efficiency and respect for everyone’s time, meetings can actually be the productive problem-solving gatherings they are supposed to be. This can only work, however, if you help foster a strong organizational culture to ensure that meetings do what they intend with as little collateral damage as possible.

Veblen and Vuitton

One day on a stroll downtown I came across a Ferrari on a surface parking lot and was immediately struck with the irresistible idea of a little social experiment. I took out my cell phone and my keys and walked up to the car as if it was mine and I was finishing up a conversation before getting in. People noticed quickly, they stared, took pictures. A crowd formed. Despite being on the phone I was interrupted twice, once by a man asking if I needed directions, and then by a pair of teenage girls who wanted to know if I knew someone whose name I couldn’t recognize so I winked and this drove them mad. I was a star, bathed in glory. Interestingly, no one asked me for spare change.

Perturbed by Rounding Error

In numerical methods it is often not possible to ignore the limitations of the tools, especially when the tool is something as basic as floating point representation. A great deal of care needs to be taken to ensure that the implementation of a numerical algorithm will be accurate despite the limits of machine precision. If instead you try to think purely in terms of the algorithm, your results may not be what you expect. Witness my recent experience adapting a classic algorithm for calculating the Normal Quantile function into Python.
