The First Free Open Source Hydroponic Nutrient Calculator Program Available Online - HydroBuddy is a completely free and open source program for the calculation of nutrient solutions for hydroponics and general agriculture built by me - Daniel Fernandez - based on my experience in hydroponics as a professional chemist. HydroBuddy is available for Linux and Windows.
The proliferation of open-source licenses is a negative aspect of the open-source movement because it is often difficult to understand the legal implications of the differences between licenses.
With more thanopen-source projects available and more than unique licenses, the complexity of deciding how to manage open-source use within "closed-source" commercial enterprises has dramatically increased.
In view of this, open-source practitioners are starting to use classification schemes in which FOSS licenses are grouped typically based on the existence and obligations imposed by the copyleft provision; the strength of the copyleft provision.
As a result, if end-users violate the licensing conditions, their license disappears, meaning they are infringing copyright.
Certification could be applied to the simplest component, to a whole software system. This project aims to build a desktop interface that every end-user is able to understand and interact with, thus crossing the language and cultural barriers.
Raymond suggests a model for developing OSS known as the bazaar model. Raymond likens the development of software by traditional methodologies to building a cathedral, "carefully crafted by individual wizards or small bands of mages working in splendid isolation".
Roles are clearly defined. Roles include people dedicated to designing the architectspeople responsible for managing the project, and people responsible for implementation.
Traditional software engineering follows the cathedral model. The bazaar model, however, is different. In this model, roles are not clearly defined.
Gregorio Robles  suggests that software developed using the bazaar model should exhibit the following patterns: Users should be treated as co-developers The users are treated like co-developers and so they should have access to the source code of the software.
Furthermore, users are encouraged to submit additions to the software, code fixes for the software, bug reportsdocumentation etc. Having more co-developers increases the rate at which the software evolves.
This new testing environment offers that ability to find and fix a new bug. Frequent integration Code changes should be integrated merged into a shared code base as often as possible so as to avoid the overhead of fixing a large number of bugs at the end of the project life cycle.
Some open source projects have nightly builds where integration is done automatically on a daily basis. Several versions There should be at least two versions of the software. There should be a buggier version with more features and a more stable version with fewer features.
The buggy version also called the development version is for users who want the immediate use of the latest features, and are willing to accept the risk of using code that is not yet thoroughly tested. The users can then act as co-developers, reporting bugs and providing bug fixes.
High modularization The general structure of the software should be modular allowing for parallel development on independent components.
Dynamic decision making structure There is a need for a decision making structure, whether formal or informal, that makes strategic decisions depending on changing user requirements and other factors. Compare with extreme programming.
Data suggests, however, that OSS is not quite as democratic as the bazaar model suggests. The average number of authors involved in a project was 5. Additionally, the availability of an open source implementation of a standard can increase adoption of that standard.
OSS also helps companies keep abreast of technology developments.Arcemu Is Moving To Git. Posted by dfighter @ November 0 Comments. Ladies and gentlemen, murlocs and gronns, orcs and elves!
The time has finally come for the Arcemu project to move over to GIT! Arcemu Is Moving To Git. Posted by dfighter @ November 0 Comments. Ladies and gentlemen, murlocs and gronns, orcs and elves! The time has finally come for the Arcemu project to move over to GIT! This paper provides quantitative data that, in many cases, open source software / free software is equal to or superior to their proprietary competition.
The paper examines market share, reliability, performance, scalability, scaleability, security, and total cost of ownership; it also comments on non-quantitative issues and unnecessary fears. Linux Kernel Networking: Implementation and Theory (Expert's Voice in Open Source) [Rami Rosen] on arteensevilla.com *FREE* shipping on qualifying offers.
Linux Kernel Networking takes you on a guided in-depth tour of the current Linux networking implementation and the theory behind it. Linux kernel networking is a complex topic. On December 29, , the U.S. Environmental Protection Agency established the Chesapeake Bay Total Maximum Daily Load (TMDL).
The TMDL is a historic and comprehensive "pollution diet" to restore clean water in the Chesapeake Bay and the region's streams, creeks, and rivers.
A . According to the Free software movement's leader, Richard Stallman, the main difference is that by choosing one term over the other (i.e.
either "open source" or "free software") one lets others know about what one's goals are: "Open source is a development methodology; free software is a social movement." Nevertheless, there is significant overlap between open source software and free .
