I survived the Warsaw ghetto. Here are the lessons I’d like to pass on | Stanisław Aronson | Opinion | The Guardian
> The truth is that, as a Pole and as a Jew, as a soldier and as a refugee, I experienced a wide spectrum of behaviour at the hands of Poles – from those who sheltered me at risk to their own lives, to those who sought to take advantage of my vulnerability, and all possible shades of concern and indifference in between.
> And although the Third Reich destroyed my world, it was a German woman who saved my life by introducing me to the men who would recruit me into the Polish underground. No nation has a monopoly on virtue – something that many people, including many of my fellow Israeli citizens, still struggle to understand.

Ask HN: What you wish you'd known before getting into JavaScript? | Hacker News
> I answered this specific question with this post a few years ago, and mostly the advice holds true today.
> If I could offer one single piece of advice that would save you hours, weeks and months of pain, it would be to use "create-react-app" which neatly sidesteps ALL of the pain arising from using the JavaScript toolchain. This is presuming you are going to use ReactJS.
create-react-app is a hundredfold more valuable than any other single thing to the JavaScript beginner. Maybe 200 fold.
Without create-react-app you'll rapidly sink to the 9th level of hell where the King Demon of JavaScript toolchains will torture you so unrelentingly that you'll beg for mercy and return to the safety of Python and leave your JavaScript goal to some other year.

Cool Backgrounds
The image discovery problem first emerged while working on tutorials for HTML Color Codes. With somewhat dry material like HTML code, it's hard to create a compelling image that represents the actual power of that knowledge. Trianglify.js to the rescue! Utilizing the javascript library, we added our brand colors and generated a high resolution image that looked amazing. To this day we still get random emails asking us how we created that background 😄.

Announcing Sourcegraph Server 2.4: free, powerful search for your private code

By Quinn Slack on January 9, 2018
Sourcegraph Server 2.4 is here. It is now free for unlimited users and repositories, can be installed in minutes with a single docker run command, and is easily configurable in the new web-based site admin. This release also includes many performance and bug fixes, plus a better interface for monitoring search results.

Sourcegraph Server gives the power of great code search to every developer at your company, so you can ship better code faster. It runs securely in your own network, takes 5 minutes to install, and is easy to upgrade.

Poetry Daily Prose Feature - Emily Wilson: Translator's Note to The Odyssey
The notion that Homeric epic must be rendered in grand, ornate, rhetorically elevated English has been with us since the time of Alexander Pope. It is past time, I believe, to reject this assumption. Homer's language is markedly rhythmical, but it is not difficult or ostentatious, The Odyssey relies on coordinated, not subordinated syntax ("and then this, and then this, and then this," rather than "although this, because of that, when this, which was this, on account of that")

Hey Siri: An On-device DNN-powered Voice Trigger for Apple’s Personal Assistant - Apple
The microphone in an iPhone or Apple Watch turns your voice into a stream of instantaneous waveform samples, at a rate of 16000 per second. A spectrum analysis stage converts the waveform sample stream to a sequence of frames, each describing the sound spectrum of approximately 0.01 sec. About twenty of these frames at a time (0.2 sec of audio) are fed to the acoustic model, a Deep Neural Network (DNN) which converts each of these acoustic patterns into a probability distribution over a set of speech sound classes: those used in the “Hey Siri” phrase, plus silence and other speech, for a total of about 20 sound classes. See Figure 2.
The DNN consists mostly of matrix multiplications and logistic nonlinearities. Each “hidden” layer is an intermediate representation discovered by the DNN during its training to convert the filter bank inputs to sound classes. The final nonlinearity is essentially a Softmax function (a.k.a. a general logistic or normalized exponential), but since we want log probabilities the actual math is somewhat simpler.

Why Momentum Really Works
Here’s a popular story about momentum [1, 2, 3]: gradient descent is a man walking down a hill. He follows the steepest path downwards, his progress is slow, but steady. Momentum is a heavy ball rolling down the same hill. The added inertia acts both as a smoother and an accelerator, dampening oscillations and causing us to barrel through narrow valleys, small humps and local minima.

This standard story isn’t wrong, but it fails to explain many important behaviors of momentum. In fact, momentum can be understood far more precisely if we study it on the right model.

One nice model is the convex quadratic. This model is rich enough to reproduce momentum’s local dynamics in real problems, and yet simple enough to be understood in closed form. This balance gives us powerful traction for understanding this algorithm.

Seeing Theory
Seeing Theory is a project designed and created by Daniel Kunin with support from Brown University's Royce Fellowship Program and National Science Foundation group STATS4STEM. The goal of the project is to make statistics more accessible to a wider range of students through interactive visualizations.

Statistics, is quickly becoming the most important and multi-disciplinary field of mathematics. According to the American Statistical Association, statistician is one of the top ten fastest-growing occupations and statistics is one of the fastest-growing bachelor degrees. Statistical literacy is essential to our data driven society. Yet, for all the increased importance and demand for statistical competence, the pedagogical approaches in statistics have barely changed. Using Mike Bostock’s data visualization software, D3.js, Seeing Theory visualizes the fundamental concepts covered in an introductory college statistics or Advanced Placement statistics class. Students are encouraged to use Seeing Theory as an additional resource to their textbook, professor and peers.

In this article we will analyze a dataset from the California Department of Water Resources (CDWR) looking at the several vital statistics for the Oroville dam. This article provides realtime analysis with Chart Lab graphs (updated hourly and automatically with data taken from the CDWR website), which show the current situation at the dam. Additionally, this article illustrates how publicly available data from the California DWR can be easily loaded into the non-relational Axibase Time Series Database (ATSD) for interactive analysis with graphical representation of open data published by government organizations.

Super-Saturated Chemistry | Articles | Inference: International Review of Science
Chemists can calculate the energy or length of any chemical bond, but it has never been explained in the context of quantum mechanics. The very concept of a chemical bond, while immeasurably useful, is a seductive abstraction, Charles Coulson observed:

> Sometimes it appears to me that a bond between two atoms has become so real, so tangible, so familiar that I can almost see it. But then I awake with a little shock: for the chemical bond is not a real thing, it does not exist, and no one has ever seen or will ever see it. It is a figment of our imagination.19

Glance is a visual syntax for the programming language Haskell. The goal of this project is to increase programmer happiness and productivity by allowing programmers to create and understand programs in new and different ways. Currently, the Glance executable produces a visual representation of your code in the form of an SVG image when given a textual Haskell source file. In the future, I hope to create a visual editor for Haskell. Please scroll down to see some example images.

Quine8 (Q8) is a simple virtual machine that takes the most basic building block a computer can operate on, bytecode and runs it at a fraction of the speed of a real CPU, allowing you to watch it run each step of the way.
