These are good calculations. I think many people would like to go to a significantly larger field of view than 40 degrees. 40 degrees horizontally is not that much: the human visual field is over 200 degrees.

OLED-on-glass-substrate is allowing TVs to get lighter making them more installable. OLED-on-plastic-substrate TVs could be shipped rolled up. They may not be that far away (<10 years).

The older copy of the US site at https://web.archive.org/web/20180206011840/https://www.42.us... is very clear: "I AM NOT BETWEEN THE AGES OF 18 AND 30. CAN I COME TO 42? No. While we do not have anything against those who are over 30 years old, when opening a new location, we have decided to concentrate our where they can be the most efficient and where we have a great deal of experience."

On the current site this is changed to: "You can apply to 42 if you’re older than 45, but please know that most students here are younger and that Intensive Basic Training is tiring."

Hardly encouraging.

The french site http://www.42.fr/ says "ouverte à tous et accessible aux 18-30 ans" (18-30 only)

This article might be one of the best intros: Space-Time Approach to Non-Relativistic Quantum Mechanics R. P. Feynman Rev. Mod. Phys. 20, 367 – Published 1 April 1948

Caltech has this available: http://authors.library.caltech.edu/47756/1/FEYrmp48.pdf

There are some other good treatments too, although I can't find them at the moment.

Following Gladwell's 10000 hour rule, I would say you could probably call yourself a data science after 1000+ hours experience working with datasets successfully. As far as the math goes you should be able to do regression analysis, you don't need to know tons of stats but you do need to know stats and probability essentials (first few classes at a good school) deeply. I like this Wikipedia entry on "mathematical maturity": http://en.wikipedia.org/wiki/Mathematical_maturity; apart from writing proofs, it is very relevant.

I haven't seen any lab demonstrations of multi Mbit devices. Until we see that this is years away from production in my experience as a device physics researcher. All storage technologies so far have taken 10 years plus to have large market share and I don't see this as an exception.
Flock math department here. Robots are software-limited, and Flock has more overlap with robotics on the software side than people might think. At Bump we have been writing software to exchange bits of stuff between computers that 50% of the population has attached to their bodies. Flock is actively making decisions for the human based on situational awareness. The machine learning and statistical techniques we are using are the same ones that are being using in robotics for e.g. situational awareness and path/task planning.

If anyone out there is interested in being a developer in my group and is handy with algorithms and fast data stores e.g. Redis, ideally in production, email me.

If anyone wants to do some very interesting contract work in machine learning (SVMs) for a YC company, please mail me. [edit: email address now in my profile oops]

Re:Don't use Scatterplots on Saturday May 26, 2012 @02:53PM (#4028025)
Don't use Density Plots ..

... without seriously considering the benefits of a scatterplot.

Here is some data I plotted recently: http://i.imgur.com/lvraM.png

Yes, you need to be careful about overlap (transparency can help), but without a scatterplot, I would not see the sharp edges, or have my attention drawn to the outliers.

Density plots imply a model: By creating bins, square or hex, you are adding a layer of interpretation on top of the 2D data, which can be bad. Also the bins of this article have sharp edges (high frequency content) and add artificial structure. I think smooth density plots, not covered by this article, are superior.

Best of both worlds? --> http://www.survey-design.com.au/graphs/density_plot1.png

Bump has one engineer in Tokyo and we may expand, probably on front-end mobile (iOS or Android). Our lead product the Bump app is the 5th most popular app of all time in Japan.

Use machine learning to fundamentally change the way people interact

To our users, Bump is a magical experience. What they don’t see is the math behind the scenes that detects a gesture and determines precisely which two phones bumped together in surprisingly creative ways. With our next wave of (still secret) products, machine learning will have an even greater user-facing impact.At Bump you can use your machine learning expertise to directly enable new user...
