Blake Matheny: Tumblr Firehose - The Gory Details →
mobocracy:
Back in December I started putting some thought into the tumblr firehose. While the initial launch was covered here, and the business stuff surrounding it was covered by places like techcrunch and AllThingsD, not much has been said about the technical details.

parislemon:
Twitter has drafted up what they’re calling the Innovator’s Patent Agreement (IPA). With it, the company is promising to only use their patents as the actual inventor intended — read: defensively, not offensively.
More specifically:
The IPA is a new way to do patent assignment that keeps control in the hands of engineers and designers. It is a commitment from Twitter to our...
Tumblr Engineering: Tumblr Fire Hose →
engineering:
We hear quite a bit about BIG DATA and REAL-TIME stuff. But I’m never sure exactly how BIG the data is or how REAL the time is. Seems like these are often just cool words that the cool kids like to throw around. The Tumblr engineering staff is too busy to worry about being cool, but we do have BIG…

Interesting paper about how our perception of how others expect us not to feel negative emotions ends up making us experiencing more negative emotions.

Bayes Reloaded
Nice post on Bayesian recommendation systems.
informationflow:
In our last episode, we learned that there’s a big difference between liking most of the books your friend reads and your friend liking most of the books which you read. That’s pretty obvious by itself, though we did get a nicely specific number for just how likely your friend is to like a book which you like. But we were trying...

iam.al: This week's underused Python module: array →
thatdatabaseguy:
I do a lot of work with sparse matrices. A common example is a term-document matrix where \( X_{i,j} = \#\ of\ times\ word\ W_j\ occurs\ in\ document\ D_i \). Representing this as a dense matrix would be silly since most of the values are 0. Hence we have sparse matrices, available to the Python…
