MORF: a Framework for Predictive Modeling and Replication at Scale with Privacy-Restricted MOOC Data
MORF: A Framework for Predictive Modeling and Replication At Scale With Privacy-Restricted MOOC Data Josh Gardner, Christopher Brooks Juan Miguel Andres, Ryan S. Baker School of Information Graduate School of Education The University of Michigan The University of Pennsylvania Ann Arbor, USA Philadelphia, USA fjpgard, [email protected] [email protected], [email protected] Abstract—Big data repositories from online learning plat- ing. For example, several works have explored prediction forms such as Massive Open Online Courses (MOOCs) rep- of various student outcomes using behavioral, linguistic, resent an unprecedented opportunity to advance research and assignment data from MOOCs to evaluate and predict on education at scale and impact a global population of learners. To date, such research has been hindered by poor various student outcomes including course completion [1], reproducibility and a lack of replication, largely due to three [2], [3], assignment grades [4], Correct on First Attempt types of barriers: experimental, inferential, and data. We (CFA) submissions [5], student confusion [6], and changes present a novel system for large-scale computational research, in behavior over time [7]. A key area of research has been the MOOC Replication Framework (MORF), to jointly address methods for feature engineering, or extracting structured these barriers. We discuss MORF’s architecture, an open- source platform-as-a-service (PaaS) which includes a simple, information from raw data (i.e. clickstream server logs, flexible software API providing for multiple modes of research natural language in discussion posts) [8].

Ubuntu Kung Fu
Prepared exclusively for Alison Tyler Download at Boykma.Com What readers are saying about Ubuntu Kung Fu Ubuntu Kung Fu is excellent. The tips are fun and the hope of discov- ering hidden gems makes it a worthwhile task. John Southern Former editor of Linux Magazine I enjoyed Ubuntu Kung Fu and learned some new things. I would rec- ommend this book—nice tips and a lot of fun to be had. Carthik Sharma Creator of the Ubuntu Blog (http://ubuntu.wordpress.com) Wow! There are some great tips here! I have used Ubuntu since April 2005, starting with version 5.04. I found much in this book to inspire me and to teach me, and it answered lingering questions I didn’t know I had. The book is a good resource that I will gladly recommend to both newcomers and veteran users. Matthew Helmke Administrator, Ubuntu Forums Ubuntu Kung Fu is a fantastic compendium of useful, uncommon Ubuntu knowledge.

Final Exam Review History of Science 150
Final Exam Review History of Science 150 1. Format of the Exam 90 minutes, on canvas 12:25pm December 18. You are welcome to bring notes to the exam, so you could start by filling out this sheet with notes from lectures and the readings! Like the mid-term, the final exam will have two kinds of questions. 1) Multiple choice questions examining your knowledge of key concepts, terms, historical developments, and contexts 2) Short answer questions in which ask you to draw on things you’ve learned in the course (from lecture, readings, videos) to craft a short argument in a brief essay expressing your informed issue on a historical question 2. Sample Questions Multiple Choice: Mina Rees was involved in (and wrote about) which of the following computing projects? A) Silicon Valley start-ups in the dot-com period B) Charles Babbage’s Difference Engine C) Works Projects Administration Tables Project D) Federal funding for computing research after WWII Short Answer: (Your answers should be between 100-200 words, and keep to specifics (events, machines, developments, people) that demonstrate your knowledge of materials covered from the course) A) What are two historical factors important to the development of Silicon Valley’s technology industry after World War II? B) In what ways did the field of programming change (in terms of its status and workers) between World War II and the late 1960s? 3. Topics to Review: Below, is a list of ideas to review for the final exam, which covers material through the entire course. You should review in particular, lecture notes, O’Mara’s The Code and other course readings provided on Canvas. -
Linux at 25 PETERHISTORY H
Linux at 25 PETERHISTORY H. SALUS Peter H. Salus is the author of A n June 1991, at the USENIX conference in Nashville, BSD NET-2 was Quarter Century of UNIX (1994), announced. Two months later, on August 25, Linus Torvalds announced Casting the Net (1995), and The his new operating system on comp.os.minix. Today, Android, Google’s Daemon, the Gnu and the Penguin I (2008). [email protected] version of Linux, is used on over two billion smartphones and other appli- ances. In this article, I provide some history about the early years of Linux. Linus was born into the Swedish minority of Finland (about 5% of the five million Finns). He was a “math guy” throughout his schooling. Early on, he “inherited” a Commodore VIC- 20 (released in June 1980) from his grandfather; in 1987 he spent his savings on a Sinclair QL (released in January 1984, the “Quantum Leap,” with a Motorola 68008 running at 7.5 MHz and 128 kB of RAM, was intended for small businesses and the serious hobbyist). It ran Q-DOS, and it was what got Linus involved: One of the things I hated about the QL was that it had a read-only operating system. You couldn’t change things ... I bought a new assembler ... and an editor.... Both ... worked fine, but they were on the microdrives and couldn’t be put on the EEPROM. So I wrote my own editor and assembler and used them for all my programming. Both were written in assembly language, which is incredibly stupid by today’s standards. -
Annex I Definitions
Annex I Definitions Free and Open Source Software (FOSS): Software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees. Open source code evolves through community cooperation. These communities are composed of individual programmers and users as well as very large companies. Some examples of open source initiatives are GNU/Linux, Eclipse, Apache, Mozilla, and various projects hosted on SourceForge1 and Savannah2 Web sites. Proprietary software -- Software that is distributed under commercial licence agreements, usually for a fee. The main difference between the proprietary software licence and the open source licence is that the recipient does not normally receive the right to copy, modify, redistribute the software without fees or royalty obligations. Something proprietary is something exclusively owned by someone, often with connotations that it is exclusive and cannot be used by other parties without negotiations. It may specifically mean that the item is covered by one or more patents, as in proprietary technology. Proprietary software means that some individual or company holds the exclusive copyrights on a piece of software, at the same time denying others access to the software’s source code and the right to copy, modify and study the software. Open standards -- Software interfaces, protocols, or electronic formats that are openly documented and have been accepted in the industry through either formal or de facto processes, which are freely available for adoption by the industry. The open source community has been a leader in promoting and adopting open standards. Some of the success of open source software is due to the availability of worldwide standards for exchanging information, standards that have been implemented in browsers, email systems, file sharing applications and many other tools.
