Eucalyptus in the cloud: researchers commercialize OSS project - Ars Technica The Eucalyptus project, which aims to provide open source infrastructure for cloud computing, is growing beyond its university roots and is heading straight for enterprise data centers. The key developers behind the project have launched a company with the intent of commercializing the technology, and have received $5.5 million in venture capital funding to get them started. Eucalyptus can be used to build elastic computing environments—like Amazon EC2—on top of conventional clusters. It provides infrastructure for automating virtual machine provisioning and management so that a cluster's computational resources can be made accessible to users in a more flexible way. It leverages the open source Xen hypervisor and it is designed to run on the Linux platform. Its management APIs are modeled after those provided by EC2, which means that it is largely compatible with tools that are built to work with Amazon's service.
6 Ed Tech Tools to Try in 201 6 About a year ago, I published an e-book called the Teacher’s Guide to Tech. Over the last month, I have been updating it for 2016, adding over 30 new tools and refreshing the information I had about the original ones. I have to say, the 2015 version was excellent, but now it’s SO MUCH BETTER. (To take a peek at the guide, scroll to the bottom of this post.) In the process, I discovered some tools that I absolutely fell in love with, and I wanted to share them with you here. Each of these tools can make your teaching more efficient and effective, and your students’ learning deeper and more engaging.
Contributing to Open Source Projects HOWTO This page is aimed at programmers new to the Open Source / Free Software world, who want to make a contribution, but aren't sure where to start. The latest version of this document is at www.kegel.com/academy/opensource.html. Contents Triage Triage is the fine art of looking at bug reports from users, deciding if they're repeatable, and if so, passing the proper information on to the developers. This is a great way to get familiar with a project, and to earn karma points.
Libraries Below is a list of libraries, products, and tools implementing current OpenID specifications and related specs. While several of these implementations have been tested, they are maintained by members of the OpenID community or vendors and are not necessarily known to work. Please review the documentation and test your own implementation thoroughly before releasing to the public.
DVCS-Autosync: A personal Dropbox replacement based on Git Executive summary dvcs-autosync is a project to create an open source replacement for Dropbox/Wuala/Box.net/etc. based on distributed version control systems (DVCS). It offers nearly instantaneous mutual updates when a file is added or changed on one side but with the added benefit of (local, distributed) versioning and that it does not rely on a centralized service provider, but can be used with any DVCS hosting option including a completely separate server - your data remains your own. Synchronization of directories is based on DVCS repositories.
untitled The GNU operating system is a complete free software system, upward-compatible with Unix. GNU stands for “GNU's Not Unix”. Richard Stallman made the Initial Announcement of the GNU Project in September 1983. A longer version called the GNU Manifesto was published in March 1985. Why I’m not an open source person any more I’ve been having this conversation a bit lately so I just wanted to put it out there. From 1998-2007 I worked full time in open source software. I considered myself a member of the open source community. Open source was kind of my “thing”. This is no longer true. Calculate Linear Regression and Graph Scatter Plot and Line of Best Fit What is simple linear regression? Simple linear regression is a way to describe a relationship between two variables through an equation of a straight line, called line of best fit, that most closely models this relationship. A common form of a linear equation in the two variables x and y isy=mx+b where m and b designate constants. The origin of the name "e;linear"e; comes from the fact that the set of solutions of such an equation forms a straight line in the plane. In this particular equation, the constant m determines the slope or gradient of that line, and the constant term "b" determines the point at which the line crosses the y-axis, otherwise known as the y-intercept. Given any set of n data points in the form (x_i, y_i), according to this method of minimizing the sum of square errors, the line of best fit is obtained whenm\sum_{i=1}^{n} x_i+bn=\sum_{i=1}^{n} y_im\sum_{i=1}^{n} x_i^2+b\sum_{i=1}^{n} x_i=\sum_{i=1}^{n} x_iy_i where the summations are taken over the entire data set.
Linus Torvalds and Others on Community Burnout Hang around the free and open source software community for any length of time, and you can't help seeing examples of burnout. A colleague takes on too much, and suddenly they're working harder for fewer results. They have a hard time concentrating on their work. They neglect their personal life.

(See 2010's Open Source Apps: the Ultimate List and 2009's Open Source Software: The Monster List.) This year's retrospective is bigger than ever with 957 excellent open source applications featured. The complete list is a lot to handle in one sitting, so we've divided it into categories.
