Solving problems with startups

Thursday, November 27th, 2014

Interesting insider Q&A with Paul Sutter, co-founder of Quantcast. Via Hacker News:

Q: What methodical process did you follow for your startup? Did you first test the market using tactics similar to the lean startup approach?

A: Basically, make a list of known problems that you’re well suited to solving, rank them by criteria, fail a lot, bang your head against the wall, and eventually things start to stick.

Web interest in Apache Storm, Kafka, Spark in the Python community

Thursday, November 27th, 2014

Apache Storm, Kafka, and Spark are gaining a lot of momentum in the data analysis and processing communities. I was curious whether the interest in using these technologies with Python, in particular, is growing. Based on these Google Trends reports, it seems like it is.

Everybody Worships

Wednesday, November 26th, 2014

From David Foster Wallace’s Kenyon College commencement speech, “This is Water”.

Everybody worships.

The only choice we get is what to worship. And the compelling reason for maybe choosing some sort of god or spiritual-type thing to worship — be it JC or Allah, be it YHWH or the Wiccan Mother Goddess, or the Four Noble Truths, or some inviolable set of ethical principles — is that pretty much anything else you worship will eat you alive.

If you worship money and things, if they are where you tap real meaning in life, then you will never have enough, never feel you have enough.

It’s the truth.

Worship your body and beauty and sexual allure and you will always feel ugly. And when time and age start showing, you will die a million deaths before they finally grieve you.

On one level, we all know this stuff already. It’s been codified as myths, proverbs, clichés, epigrams, parables; the skeleton of every great story. The whole trick is keeping the truth up front in daily consciousness.

Worship power, you will end up feeling weak and afraid, and you will need ever more power over others to numb you to your own fear.

Worship your intellect, being seen as smart, you will end up feeling stupid, a fraud, always on the verge of being found out.

But the insidious thing about these forms of worship is not that they’re evil or sinful, it’s that they’re unconscious. They are default settings.

They’re the kind of worship you just gradually slip into, day after day, getting more and more selective about what you see and how you measure value without ever being fully aware that that’s what you’re doing.

Listen to the full audio, it’s only ~20mins. Worth it.

Clojonic: Pythonic Clojure

Sunday, November 2nd, 2014

In June 2012, I promised myself that I’d learn Clojure “as a mind expander”. As a long-time Python programmer who has been using Python full-time in my work at, I wanted to explore. I wrote then:

I don’t know whether Clojure programs will be better or worse than equivalent Python programs. But I know they will be different.

It took me awhile, but in January of this year, I started teaching myself the language.

Rich Hickey, and the “Cult of Personality”

My approach was to first learn the underpinnings of the language from books and online videos. If you embark on this for Clojure, you will inevitably run into the copious publicly-available material from the language’s creator, Rich Hickey.

In stark contrast to Guido van Rossum in the Python community, Rich Hickey is undeniably not just the Clojure language’s creator, but also a kind of spokesperson for a functional programming renaissance. Guido van Rossum generally lays low and lets the Python language and community speak for itself, and tries to avoid controversy. To him, Python is just a popular tool he happened to create, and it doesn’t represent any major paradigm shift in programming. It’s a positive evolutionary improvement supported by a great open source ecosystem and community. To Hickey, however, “traditional” programming languages — but especially popular ones with an object-oriented focus, such as Java and C++ — are just plain wrong. He proposes Clojure as an antidote of sorts.

You can get the gist of this from his motivating videos, such as Hammock-Driven Development, Are We There Yet?, and Simple Made Easy. For a thorough overview of Clojure as a language, you can also get a walkthrough by Hickey, given to a room full of Java developers, in Clojure for Java Programmers Part I and Part II.

Here is a summary of the viewpoint. Most languages are missing some important attributes that can help us tackle the most complex issues in programming projects:
