White Fragility: Why It's So Hard to Talk to White People About Racism - The Good Men Project
This systemic and institutional control allows those of us who are white in North America to live in a social environment that protects and insulates us from race-based stress. We have organized society to reproduce and reinforce our racial interests and perspectives. Further, we are centered in all matters deemed normal, universal, benign, neutral and good. Thus, we move through a wholly racialized world with an unracialized identity (e.g. white people can represent all of humanity, people of color can only represent their racial selves).

Challenges to this identity become highly stressful and even intolerable. The following are examples of the kinds of challenges that trigger racial stress for white people:

From Yosemite to Bears Ears, Erasing Native Americans From U.S. National Parks
Though the National Park Service prevented wholesale industrialization, they still packaged the wilderness for consumption, creating a scenic, pre-historical fantasy surrounded by roads and tourist accommodations, all designed to mask the violence inherent to these parks’ creation. More than a century later, the United States has done little to acknowledge the government-led genocide of native populations, as well as the continued hardships they face because of the many bad-faith treaties enacted by the U.S. government. This story is an elemental part of our National Park system, the great outdoor museum of the American landscape, but the myth continues to outweigh the truth. How did the National Park Service evict Yosemite’s indigenous communities and erase their history, and can it come to terms with this troubling legacy today?

An overview of gradient descent optimization algorithms
Gradient descent is one of the most popular algorithms to perform optimization and by far the most common way to optimize neural networks. At the same time, every state-of-the-art Deep Learning library contains implementations of various algorithms to optimize gradient descent (e.g. lasagne's, caffe's, and keras' documentation). These algorithms, however, are often used as black-box optimizers, as practical explanations of their strengths and weaknesses are hard to come by.

This blog post aims at providing you with intuitions towards the behaviour of different algorithms for optimizing gradient descent that will help you put them to use. We are first going to look at the different variants of gradient descent. We will then briefly summarize challenges during training. Subsequently, we will introduce the most common optimization algorithms by showing their motivation to resolve these challenges and how this leads to the derivation of their update rules. We will also take a short look at algorithms and architectures to optimize gradient descent in a parallel and distributed setting. Finally, we will consider additional strategies that are helpful for optimizing gradient descent.

Gradient descent is a way to minimize an objective function J(θ)
J
(
θ
)
parameterized by a model's parameters θ∈ℝd
θ

R
d
by updating the parameters in the opposite direction of the gradient of the objective function ∇θJ(θ)

θ
J
(
θ
)
w.r.t. to the parameters. The learning rate η
η
determines the size of the steps we take to reach a (local) minimum. In other words, we follow the direction of the slope of the surface created by the objective function downhill until we reach a valley. If you are unfamiliar with gradient descent, you can find a good introduction on optimizing neural networks here.

YOMP NOTES - HIKES, TRAILS & the KIT to get it DONE!: GORUCK GR1 Rucksack, EDC No1.
An EDC (Every Day Carry) can be all kinds of things to all sorts of people. It is the gear we carry every day. Our Keys, phone, a knife maybe a torch another knife and so on.
Some carry this equipment in their pockets, others in organised zip around pouches and others in their rucksacks, that's me that's what I do, I carry in my rucksack because I tried the others and for me, a rucksack works best.

"How Heritability Misleads about Race" by Ned Block
According to The Bell Curve, Black Americans are genetically inferior to Whites. That's not the only point in Richard Herrnstein and Charles Murray's book. They also argue that there is something called "general intelligence" which is measured by IQ tests, socially important, and 60 percent "heritable" within whites. (I'll explain heritability below.) But the claim about genetic inferiority is my target here. It has been subject to wide-ranging criticism since the book was first published last year. Those criticisms, however, have missed its deepest flaws. Indeed, the Herrnstein/Murray argument depends on conceptual confusions that have been tacitly accepted to some degree by many of the book's sharpest critics.

Let's first be clear about the conclusion itself. In a recent article on "The Real Bell Curve," Charles Murray grumbles about critics, such as Stephen Jay Gould, who read the book as saying that racial differences in IQ are mostly genetic. Murray answers by quoting from the book:

If the reader is now convinced that either the genetic or environmental explanations have won out to the exclusion of the other, we have not done a sufficiently good job of presenting one side or the other. It seems highly likely to us that both genes and environment have something to do with racial differences. What might the mix be? We are resolutely agnostic on that issue; as far as we can determine, the evidence does not yet justify an estimate (311).

In this passage, Herrnstein and Murray are "resolutely agnostic" about whether bad environment or genetic endowment is more responsible for the lower IQs of Blacks. But they indicate no agnosticism at all about whether part of the IQ difference between Blacks and Whites is genetic; and given their way of thinking about the matter, this means that they are not at all agnostic about some Black genetic inferiority.

Chinese Zodiac Pentominoes by msraynsford - Thingiverse
Looking to remake of the original puzzle by Sabu Oguro, I stumbled across a set of dxf files for each piece already on thingiverse
http://www.thingiverse.com/thing:1453

I ended up modifying each file to round off the corners and create a single path for the laser to cut around, I also added a tray to hold all the pieces in the basic shape.

My original post about these can be found here

Star Trek: Voyager – A Viewer's Guide - Google Sheets
I have published a viewing guide to Star Trek: Voyager. It’s a big project that I’ve worked on as a hobby for over a year in an effort to provide a constructive response to those who have watched a few random episodes and declared Voyager is not good.

I have 95 episodes to recommend, about 60% of the total. Episodes are rated:
