These are my links for October 8th through October 20th:
- sed, a stream editor – sed is a stream editor. A stream editor is used to perform basic text transformations on an input stream (a file or input from a pipeline). While in some ways similar to an editor which permits scripted edits (such as ed), sed works by making only one pass over the input(s), and is consequently more efficient. But it is sed’s ability to filter text in a pipeline which particularly distinguishes it from other types of editors.
- Best of Wikipedia – A twice-daily updated collection of some of the best reading on Wikipedia
- Axiom of Choice – The Axiom of Choice (AC) was formulated about a century ago, and it was controversial for a few of decades after that; it might be considered the last great controversy of mathematics. It is now a basic assumption used in many parts of mathematics.

- MachineLearning.pdf (application/pdf Object) – Over the past 50 years the study of Machine Learning has grown from the efforts of a handful of computer engineers exploring whether computers could learn to play games, and a field of Statistics that largely ignored computational considerations, to a broad discipline that has produced fundamental statistical-computational theories of learning processes, has designed learning algorithms that are routinely used in commercial systems
for speech recognition, computer vision, and a variety of other tasks, and has spun off an industry in data mining to discover hidden regularities in the growing volumes of online data. This document provides a brief and personal view of the discipline that has emerged as Machine Learning, the fundamental questions it addresses, its relationship to other sciences and society, and where it might be headed
- OJS Customizations | Public Knowledge Project – The Public Knowledge Project is dedicated to improving the scholarly and public quality of research. The partnership brings together faculty members, librarians, and graduate students dedicated to exploring whether and how new technologies can be used to improve the professional and public value of scholarly research. Its research program is investigating the social, economic, and technical issues entailed in the use of online infrastructure and knowledge management strategies to improve both the scholarly quality and public accessibility and coherence of this body of knowledge in a sustainable and globally accessible form. It continues to be an active player in the open access movement, as it provides the leading open source software for journal and conference management and publishing.
- Home | American Statistical Association – The American Statistical Association (ASA), a scientific and educational society founded in Boston in 1839, is the second-oldest, continuously operating professional society in the United States. For 170 years, the ASA has provided its members and the public with up-to-date, useful information about statistics. The ASA has a proud tradition of service to statisticians, quantitative scientists, and users of statistics across a wealth of academic areas and applications.

- Blind Search – Welcome to BlindSearch, the search engine taste test.Type in a search query above, hit search then vote for the column which you believe best matches your query. The columns are randomised with every query.The goal of this site is simple, we want to see what happens when you remove the branding from search engines. How differently will you perceive the results?
- Is There Reason to Be Theoretically Rational? (application/pdf Object) – An important advance in normativity research over the last decade is an increased understanding of the distinction, and difference, between normativity and rationality. Normativity concerns or picks out a broad set of concepts that have in common that they are, put loosely, guiding. For example, consider two commonly used normative concepts: that of a normative reason and that of ought. To have a normative reason to perform some action is for there to be something that counts in favour of performing that action. Likewise with ought, when there is sufficient evidence for something, one ought to believe it (at least under normal circumstances). Not all guidance need be directed towards a specific state or a specific action. Subject to the requirements of normativity, too, are relations. It is commonly believed, for example, that we ought not to hold contradictory beliefs.
- Atlas Obscura | Wondrous, curious, and bizarre locations around the world – Welcome to the Atlas Obscura, a compendium of this age’s wonders, curiosities, and esoterica. The Atlas Obscura is a collaborative project with the goal of cataloging all of the singular, eccentric, bizarre, fantastical, and strange out-of-the-way places that get left out of traditional travel guidebooks and are ignored by the average tourist. If you’re looking for miniature cities, glass flowers, books bound in human skin, gigantic flaming holes in the ground, phallological museums, bone churches, balancing pagodas, or homes built entirely out of paper, the Atlas Obscura is where you’ll find them.
These are my links for June 17th through June 18th:
- Random Walk / Daniel A. Becker – RANDOM WALK asks this question and presents experiments in mathematics and physics, showing the mysterious interaction of chaos and order in randomness.
The project RANDOM WALK simulates randomness in visualizations, which are easy to understand. In this way, it delivers insight into a phenomenon, which has so far remained unexplained.
- Nominal, Ordinal, Interval, and Ratio Typologies are Misleading (application/pdf Object) – In the following sections, we review Stevens’s taxonomy and provide definitions; many have used these terms without clarifying their exact meaning. We discuss their use in statistics and in applications, and consider some of the classical criticisms of this work. Throughout our account, we provide references for interested readers who may wish to learn more. We then describe some of the failures of Stevens’s taxonomy to classify data, and examine the nature of these failures. Similarly, we consider whether modern statistical methods can be classified according to the types of data appropriate for them. Finally, we consider what ideas from Stevens’s work are still useful for modern computer-based statistical analysis.
- Clay Shirky: How cellphones, Twitter, Facebook can make history | Video on TED.com – While news from Iran streams to the world, Clay Shirky shows how Facebook, Twitter and TXTs help citizens in repressive regimes to report on real news, bypassing censors (however briefly). The end of top-down control of news is changing the nature of politics.
- Fundamental Statistical Concepts in Presenting Data (application/pdf Object) – Principles for Constructing Better Graphics
- Statistical Modeling, Causal Inference, and Social Science – Andrew Gelman's Blog on the titular topics.
