Using org-mode as the ultimate note taking tool (updated) | Da's recipes on Emacs, IT, and more

Using org-mode as the ultimate note taking tool (updated) | Da's recipes on Emacs, IT, and more: "Whenever there is something important to memorize, I always want to write it down. In fact, Emacs org-mode makes the process easy, pleasant, and in an organized manner. I will use an example to explain how Emacs and org fit into my note-taking process.

I have a dedicated folder containing all my notes, and IT, as one of the most important topic, is a sub-folder. Here is the tree structure of the IT folder."

559 - The World’s Largest Atlas: Cheers Bests Klencke | Strange Maps | Big Think

559 - The World’s Largest Atlas: Cheers Bests Klencke | Strange Maps | Big Think: "The map is not the territory [1], but this collection gets closer than most [2]. Earth Platinum, published at the end of February in an edition limited to 31 copies, is the world’s largest atlas. The book is 1.8 m (6 ft) high and 1.4 m (4.5 ft) wide. When opened, it spans 2.8 m (9 ft). It contains 128 pages of maps, flags and panoramic photographs, and weighs 150 kg (over 300 lb). It’s the kind of book you can’t read alone: it takes two persons to turn over the gigantic pages.  "

machine learning - An example using LibSVM in python - Stack Overflow

machine learning - An example using LibSVM in python - Stack Overflow: "import numpy as NP
from svm import *

# just random generate 500 points within a given boundary:
# quite a few real data sets are are provided on the  LIBSVM [website][1]
Data = NP.random.randint(-5, 5, 1000).reshape(500, 2)

# choose some non-linear decision boundary:
# let's say that  for these 500 points, those that lie *within* an arbitrary
# circle (which i define below) are in Class I, and those
# outside this circle are Class II
rx = [ (x**2 + y**2) < 9 and 1 or 0 for (x, y) in Data ]

# to 'svm_problem' i passed in the decision boundary and the data
px = svm_problem(rx, Data)

# the kernel function i have selected is RBF (radial basis function)
pm = svm_parameter(kernel_type=RBF)

# train the classifier
v = svm_model(px, pm)

# now test it by calling 'predict' on the trained model object ('v') :
v.predict([3, 1])
# returns the class label (either '1' or '0')"
