Today we're excited to introduce a new project: Rodeo. Rodeo is an IDE that's built expressly for doing data science in Python. Think of it as a light weight alternative to the IPython Notebook. We've been using it for projects internally, but today we're releasing it to the public! We hope you like it as much as we do. Why we built it I like the IPython Notebook for presentations and tutorials, b

How to Sign In as a SPA To sign in to a Special Purpose Account (SPA) via a list, add a "+" to your CalNet ID (e.g., "+mycalnetid"), then enter your passphrase. The next screen will show a drop-down list of all the SPAs you have permission to access. Select the SPA you wish to sign in as. To sign in directly as a SPA, enter the SPA name, "+", and your CalNet ID into the CalNet ID field (e.g., âspa
A syntactic parser describes a sentenceâs grammatical structure, to help another application reason about it. Natural languages introduce many unexpected ambiguities, which our world-knowledge immediately filters out. A favourite example: They ate the pizza with anchovies A correct parse links âwithâ to âpizzaâ, while an incorrect parse links âwithâ to âeatâ: The Natural Language Processing (NLP)
I was introduced to Julia recently after hearing of Stefan Karpinski while attending HackerSchool. Julia is marketed as a super fast high performance scientific computing language that can reach speeds close to native C code. After attending a conference for Python quants in NYC and heard Dr. Yves J. Hilpisch speak on the speed of Python for financial analytics I decided to put Julia up against th
AGCA - Algebraic Geometry and Commutative Algebra Module¶ Introduction¶ Algebraic geometry is a mixture of the ideas of two Mediterranean cultures. It is the superposition of the Arab science of the lightening calculation of the solutions of equations over the Greek art of position and shape. This tapestry was originally woven on European soil and is still being refined under the influence of inte
In the first post, I took a brief look at the programming languages ATS, C#, Go, Haskell, OCaml, Python and Rust to try to decide which would be the best language in which to write 0install (which is currently implemented in Python). Now it's time to eliminate a few candidates and look in more detail at the others. Last time, I converted 4 lines of Python code from 0install into each language. Thi
