Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
one line to give the program's name and an idea of what it does. Copyright (C) yyyyname of author This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA. Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) yearname of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. signature of Ty Coon, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. More
K2 version 2.6.9 is now available to download. This is a quick maintenance release which addresses the item time problem introduced from changes in the Joomla API in the latest Joomla 3.3.x releases. The creation/modified time in K2 items would simply switch to null when editing existing K2 items. Again, this problem was caused only in the latest Joomla 3.3.x releases.
The first public beta release of K2 version 3 is finally here!
It's been more than a year's work so far designing the application and actually building it, and now we're just a few months away from the final stable 3.0.0 release!
This beta release is now available for testers and early adopters but it is NOT recommended for production websites. There are quite a few things to iron out (from parameter inheritance to frontend templates to the actual UI) and we'll use all the help we can get from your feedback in order to complete version 3.0.0.
Here's a short demo video, showcasing the responsiveness of the new UI. Yeap, it feels like a desktop grade app. K2 v3.x is running on a remote (busy) dev server.
In this first video, I'm browsing and filtering a list of 100 K2 items, by using the top filters as well as the pagination buttons. Then I switch to "infinite scrolling" mode (no pagination, just a stream of all items).
Of course there are various things to "iron out" - design wise - and small bugs, but the functionality is ready!
First and foremost: make sure your Joomla! extension or template is built to integrate with K2. If it doesn't, we won't publish it and this is not the place to submit it. There is the Joomla! Extensions Directory for that.
If it does integrate with K2, please make sure your extension and/or template meets the following guidelines before you submit it to the K2 Extensions Directory:
1) Use only the name of the extension or template, e.g. you would use "Nuevvo Toreda" but you would NOT use "Nuevvo Toreda - Responsive eCommerce Joomla Template". Instead add tags for any attributes that differentiate your product. For this example, we would add: "responsive", "ecommerce" and "template". This makes filtering e.g. only for "responsive" templates an easy process for the site's visitors.
2) Make sure your presentation HTML is clean. Do not use inline links (they will be stripped off either way), tables or other weird HTML elements (span, font etc.). Only basic HTML formatting is allowed: strong, em, ul, li, img, h3, h4, p, div, br. DO NOT colorize phrases to make them stand out.
3) Use proper English in your presentation text. If English is not your native language, ask the help of a friend. Don't use Google Translate or other non-human translation services. Spell-check what you write. Make sure it makes sense. Use the universal typing and punctuation rules (e.g. one space after a full stop or comma, no double or triple spaces between words etc. etc.). Got lists to display? Don't use a hyphen. Make sure you use HTML to display them. Use the WYSIWYG editor for that. Entries that do not meet these standards will be rejected. If you're bored to check what you write, we are 10 times bored to do it for you.
4) If you need to add links, fill in the related Extra Fields section. Make sure you fill in as much as possible beyond the required.
5) Use at least 1 image (in the Image tab) to make sure your product is properly visible on both category listings and the presentation page. Got a video? Use the Video tab as well. Got an image gallery? There's the Image Gallery tab.
6) If you are offering a free product, you can choose to upload it inside the presentation page or use an external link. That's up to you to decide. But make sure you provide an easy way for people to download your product.
If you meet the above guidelines, your extension or template will be published within one week's time after it's been carefully moderated. If you fail to meet the above guidelines, incomplete entries will be permanently deleted after 2 weeks. More
K2 version 2.6.8 is now available to download for everyone. This is a maintenance update and it includes performance optimizations & bug fixes. The highlight of this release is the switch to the InnoDB storage engine for new installations of K2. In non-geek terms this means a lot better database read/write performance on websites with high traffic and/or large number of K2 items, comments etc.
Nuevvo has just released Takai, the official K2 demo site, as a free Joomla!/K2 template, available for everyone to download and use.
This new iteration of the demo site has been fully modernized to be responsive, uses multi-color variations (with the option to create yours as well), is built using flexible grids, features cool off-canvas navigation (when on mobile) and uses Nuevvo's awesome no-framework template parameters & standard features.
Takai is the best starting point for everyone just joining the K2 Community.
So why this move to Github you ask? Well, Github will now make it a lot easier for casual developers (and experts of course) to submit code to the K2 code base. Previously this was a very tedious process with Google Code, such that most third-party additions or improvements were essentially completed manually via the bug tracker.
This also means that bug solving will now be a lot faster and more transparent.
Finally, since we're moving to a new code repo, you'll notice that http://getk2.org/bugtracker now properly redirects over to the Github "issues" section of the K2 project.
We also plan to utilize Github's "wiki" features to gradually have a proper and up-to-date documentation on the latest K2 code base.
If you haven't yet understood why, let me clarify...
The K2 Community is a very popular site. It's got an Alexa rank of about 10.000 and a 7/10 Google Pagerank. It does a little over 1 million page views per month on average. Spammers love such facts. Not spam bots, actual human spammers.
The past 2 weeks we are being heavily spammed by real human beings with regular Joomla!, Twitter or Facebook accounts (you need a mobile number to get a FB account and bots don't have mobiles). Not mention this has happened again (back when we hosted the community site on the Ning platform which is supposed to have a much better platform to fight spam)... Guess when? When effing Iron Man 2 was released. Spammers love blockbusters.
So what now?
We're temporarily disabling new user signups for a few days in order to harden security measures on the site. That includes social logins as well. Fighting real human spam is a very tough situation to deal with. That means we need to add more services like Akismet and extend the integration with StopForumSpam.com to better fight these spammers that have been identified in these huge spammer databases. We also need to improve Kunena's code to allow for quick spam user banning. And since the version of Kunena we're using won't be updated anymore, we're going to get our hands dirty :)
So please bear with us for a few days until we sort the matter. It's a tough call, but I guess it's the price to pay for a popular project.
P.S. If you need to ask a support question and you are not already a K2 Community member, please use Twitter if possible to direct your questions to @k2devs - we'll do our best to answer you there.
Update on May 15th, 2013: We have re-enabled signups to the community.More
