The freedom in the Tendenci open source software

Let’s take it again to RICHARD STALLMAN, “FOUR FREEDOMS

A program is “free software” if the program’s users have the four essential freedoms:

  1. The freedom to run the program as you wish, for any purpose.
  2. The freedom to study how the program works, and change it so it does your computing as you wish. Access to the source code is a precondition for this.
  3. The freedom to redistribute copies so you can help your neighbor.
  4. The freedom to distribute copies of your modified versions to others. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

If software is licensed in a way that does not provide these 4 freedoms, then it is categorized as nonfree or proprietary.

NonProfits and Associations Love Tendenci

Tendenci Association Websites

Written specifically for the NPO/Association market, Tendenci has continued to grow and adapt to meet the specific needs of these groups. From building on an open source framework that allows complete freedom  – to mobile responsive software design – to online forums and newsletter features that keep the community involved, Tendenci continues to invest in the NPO sector. And the NPO’s have responded!

We are pleased to continue our relationship with the following organizations that have recently released upgraded websites and extend a warm welcome to those that are new to the Tendenci community.

Why Tendenci Chose Python over PHP

Note: this is a repost from the eschipul.com blog and also lives as a help file on Tendenci.

This blog is a WordPress blog written in PHP. And WordPress, which is written in PHP is a great platform when secured properly.

So why did our team choose to rewrite Tendenci Open Source and in the Python Programming language? It is a question I get asked a lot. We’ve never been a company that likes to talk in the negative if at all possible, yet it is important to talk about the megatrends going on given we work with associations and nonprofits.

Why Python instead of PHP for Tendenci

Popularity of a language is a trend, and what you want is as many developers familiar and liking the language of your open source project as possible. This means you have a better chance to have a secure web site and therefore a more secure future.

To be fair – as Disraeli said – “lies, damn lies and statistics” – so there is no one perfectly secure language any more than there is a perfectly “safe” hammer. There will always be operator error and programmers make mistakes.

So we’re not saying Python is perfect, and all of us have used most of the other languages on those charts at some point. We’re just saying we are pleased so many other programmers also like Python and Open Source. THAT is the best that can be done to secure your future online. Secure code that you can examine yourself and even host yourself!

Addendum: As I post this on the Tendenci Blog. Given we focus on non-profits, associations, memberships, education, medical, religious – basically the do-good cause-based organizations, I believe it is particularly important that the project is as transparent as possible. Sometimes it is healthy to inform everyone of WHY we made a decision seven years ago. Python was the right call.

Tendenci Exports – Plus Easy Ways to Make Static Copies of Your Site

Today’s Tendenci community knowledge share. Here are three very easy free or low cost methods of making a static copy a web site. Use with caution, just know you have the power.

On Windows you can use HTTrack https://www.httrack.com/

On a Mac computer you can use sitesucker ($5) http://ricks-apps.com/osx/sitesucker/index.html

Of course for structured data in Tendenci, there are TONS of ways to export including exporting a copy of your entire database. There are help files on common exports like How to export your membership . There are too many options to list them all, but I’d encourage you to visit the support center or just google “tendenci exports” for more.

If you are on version 5 and want to “kick the tires” on Tendenci version 7, use https://demo.tendenci.com – you can login here https://demo.tendenci.com/accounts/login/ using “admin/admin” or “user/user”. It does reset every hour or so because of spammers but you can still get a feel for it. A HUGE upgrade from version 5.

There is also a previous post on making a static copy of your site here that is a bit more technical as well.

Why do we point out all of the ways to copy your Tendenci site (or most sites really)? Doesn’t that make it easier to leave?

Yes. Yes it does. BUT people rarely leave. Or if they do, they typically stay on Tendenci and self host. They’re still part of the Tendenci community which helps us all.

Another reason we promote exports and offsite backups is because we know the more freedom you have, realizing you have that freedom especially on the Tendenci open source platform, makes it less likely for clients to leave.

Think about it. Why would anyone who actually understands their product is open, does far more than other options, is lower cost, and they can self host if they want… why would that person make the decision to leave? It’s illogical.

I mean, who wants to be the President of an Association that takes it backwards in time to proprietary technology or an older open source software built on an unpopular programming language? That’s not in the best interests of the association long term.

Tendenci is written in Python and uses Java and Javascript libraries. This linked chart says it all.

THE 8 MOST IN-DEMAND PROGRAMMING LANGUAGES OF 2016

Popular programming languages means more coders for open source projects written in that language. And more capable people to modify and customize your install if you choose.

One of our goals is FREEDOM from the tyranny of per-user-licensing, proprietary products that want to own YOUR DATA, long term contracts, sites that post your events on THEIR site so if you leave then the history of that event is gone in the blink of an eye. Companies don’t own your data and they shouldn’t trap you.

We think that is unethical and just wrong.

Membership Management Software should be Open Source, Accessible, Responsive, and Search Engine friendly by default. Tendenci does all of those things.

Further we believe that Open Source Membership Management Software should be written in a Modern Programming Language like Python (watch out for bunnies) and the software should documented and open source (free, as in beer.) Even the US Government likes Open Source!

Want to change something? Get involved! Post on the forums at https://ww.tendenci.com/forums or post an issue at https://github.com/tendenci/tendenci/issues . If you are a programmer or into documentation, submit a pull request.

We make it easy to leave because we hope you don’t. Hence Tendenci has an incredibly low churn rate. That creates stability you can count on.
