MY'STORY

The MOVE Fire

This is a personal recollection on the Move fire on May 13, 1985 Philadelphia police fired thousands of rounds at the MOVE house, city officials approved dropping an explosive device on the roof, the resulting fire was allowed to burn, 11 people—including five children—died, and 61 homes were destroyed. Philadelphia City Council later called it a “brutal attack carried out by the City of Philadelphia on its own citizens” and acknowledged that no individual faced criminal consequences for the bombing. One timeline correction worth preserving for the BHP record: the major previous MOVE-police confrontation was August 8, 1978, about seven years before the bombing, not a year or two earlier. Officer James Ramp was killed, other police and firefighters were wounded, nine MOVE members were later convicted, and television cameras recorded police beating Delbert Africa during his arrest. The 1985 MOVE Commission later specifically criticized city planners for failing to adequately use lessons from that 1978 confrontation. And that actually strengthens the point you’re making: 1985 did not happen without precedent or institutional memory. There had already been a deadly confrontation with MOVE, years of conflict, negotiations and police involvement before Osage Avenue.

Comparison of free and open-source software licenses

This comparison covers notable software licenses which are approved by at least one of the following expert groups: the Free Software Foundation, the Open Source Initiative, the Debian Project, or the Fedora Project.

FOSS licenses

[edit]

FOSS stands for "Free and Open Source Software". There is no one universally agreed-upon definition of FOSS software and various groups maintain approved lists of licenses. The Open Source Initiative (OSI) is one such organization keeping a list of open-source licenses.[1] The Free Software Foundation (FSF) maintains a list of what it considers free.[2] FSF's free software and OSI's open-source licenses together are called FOSS licenses. There are licenses accepted by the OSI which are not free as per the Free Software Definition. The Open Source Definition allows for further restrictions like price, type of contribution and origin of the contribution, e.g. the case of the NASA Open Source Agreement, which requires the code to be "original" work.[3][4] The OSI does not endorse FSF license analysis (interpretation) as per their disclaimer.[5]

The FSF's Free Software Definition focuses on the user's unrestricted rights to use a program, to study and modify it, to copy it, and to redistribute it for any purpose, which are considered by the FSF the four essential freedoms.[6][7] The OSI's open-source criteria focuses on the availability of the source code and the advantages of an unrestricted and community driven development model.[8] Yet, many FOSS licenses, like the Apache License, and all Free Software licenses allow commercial use of FOSS components.[9]

General comparison

[edit]

For a simpler comparison across the most common licenses see free-software license comparison.

The following table compares various features of each license and is a general guide to the terms and conditions of each license, based on seven subjects or categories. Recent tools like the European Commissions' Licensing Assistant,[10] makes possible the licenses selection and comparison based on more than 40 subjects or categories, with access to their SPDX identifier and full text. The table below lists the permissions and limitations regarding the following subjects:

  • Linking - linking of the licensed code with code licensed under a different license (e.g. when the code is provided as a library)
  • Distribution - distribution of the code to third parties
  • Modification - modification of the code by a licensee
  • Patent grant - protection of licensees from patent claims made by code contributors regarding their contribution, and protection of contributors from patent claims made by licensees
  • Private use - whether modification to the code must be shared with the community or may be used privately (e.g. internal use by a corporation)
  • Sublicensing - whether modified code may be licensed under a different license (for example a copyright) or must retain the same license under which it was provided
  • TM grant - use of trademarks associated with the licensed code or its contributors by a licensee

In this table, "permissive" means the software has minimal restrictions on how it can be used, modified, and redistributed, usually including a warranty disclaimer. "Copyleft" means the software requires that its source code be made available to each user and that all provisions in the license be preserved in derivative works.

Other licenses that don't have information:

license Author Latest version Publication date
Eiffel Forum License NICE 2 2002
Intel Open Source License Intel Corporation N/a ?
RealNetworks Public Source License RealNetworks ? ?
Reciprocal Public License Scott Shattuck 1.5 2007
Sun Industry Standards Source License Sun Microsystems ? ?
Sun Public License Sun Microsystems ? ?
Sybase Open Watcom Public License Open Watcom N/a 2003-01-28
Zope Public License Zope Foundation 2.1 ?
Server Side Public License MongoDB 1.0 2018-10-16

Approvals

[edit]

This table lists for each license what organizations from the FOSS community have approved it – be it as a "free software" or as an "open source" license – , how those organizations categorize it, and the license compatibility between them for a combined or mixed derivative work. Organizations usually approve specific versions of software licenses. For instance, a FSF approval means that the Free Software Foundation (FSF) considers a license to be free-software license. The FSF recommends at least "Compatible with GPL" and preferably copyleft. The OSI recommends a mix of permissive and copyleft licenses, the Apache License 2.0, 2- & 3-clause BSD license, GPL, LGPL, MIT license, MPL 2.0, CDDL and EPL.

  1. ^ The original version of the Artistic License is defined as non-free because it is overly vague, not because of the substance of the license. The FSF encourages projects to use the Clarified Artistic License instead.
  2. ^ But can be made compatible by upgrading to GPLv3 via the optional "or later" clause added in most GPLv2 license texts.
  3. ^ But not with GPLv2 without "or later" clause.
  4. ^ MPL 2.0 is GPL compatible unless marked "Incompatible with Secondary Licenses".
  5. ^ Listed as WTFPL.

No. Some of the requirements in GPLv3, such as the requirement to provide Installation Information, do not exist in GPLv2. As a result, the licenses are not compatible: if you tried to combine code released under both these licenses, you would violate section 6 of GPLv2. However, if code is released under GPL "version 2 or later," that is compatible with GPLv3 because GPLv3 is one of the options it permits.

Internet forum

An Internet forum, or message board, is an online discussion platform where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible. The name comes from the forums of Ancient Rome. Forums have a specific set of jargon associated with them; for example, a single conversation is called a "thread" or "topic". A discussion forum is hierarchical or tree-like in structure; a forum can contain a number of sub-forums, each of which may have several topics. Depending on the forum's settings, users can be anonymous or have to register with the forum and then subsequently log in to post messages. On most forums, users do not have to log in to read existing messages.
