So first things first, I want to develop a system for display on here.

I spent some playing around with various plugins and utilities to provide image display within WordPress. I’d been half-using NextGEN Gallery but its back-end started playing up. Well, for me at least. I could no longer drag and drop albums into galleries (or was it galleries into albums) .

It was all enough of an incentive to try and find something new. Also, I could never get my head round the gallery/album concept in NextGEN and I had to relearn the terminology every time I wanted to make new collections of images. Don’t get me wrong, NextGEN is a fine plugin, it’s just not for me.

I’ve plumped for a swiss army-knife method of using two or three plugins. It’s probably way over the top but I’m happy with what I’ve ended up with:

Shashin

Shashin is apparently the Japanese word for photograph. It’s also the name of this very extensive plugin to pull in images from a Picasa account. I’ve also had a Picasa account for a long time and used it as a backup for Flickr.

The Shashin plugin is so good that after playing around with it I’ve left it installed here. I probably won’t use it as the primary image display tool, but I like it nevertheless.

ZenphotoPress

I have a love/don’t-love-so-much relationship with ZenPhoto. I’ve installed, then deleted it many times but I always come back to it. It’s a full-on photo-hosting utility and can be used as a stand alone website or as a sub-directory of an existing site.

One of the things I do like about ZenPhoto is two 3rd party WordPress plugins, the first of which is Zenphotopress.

Here’s a selection of thumbnails from a ZenPhoto album:

[zenphotopress album=8 sort=random number=12]

And here’s a single image:

ZenPhoto Short Tags

ZenPhoto Short Tags This is the second ZenPhoto plugin I like and it’s really simple to use. It scales a ZenPhoto image on the fly and you can display that image anywhere on the site with this simple tag:

[zp  src="03012011.jpg" album="365" width="940"]

This post is a reaction to, or perhaps it’s better described as my thoughts on, the situation that exists regarding WordPress and its licence, the GNU General Public License (GPL).

I’m also going to be quoting and answering points raised on Liz Jamieson’s website over at Big Satchurday. Liz wrote a blog-post titled Thesis, The GPL and WordPress – What Does It All Mean? which was prompted by a discussion over at Mixergy between Mat Mullenweg and Chris Pearson. Mat is a lead developer at WordPress and is its public face. Chris is the developer of Thesis, a theme for WordPress.

I was going to reply to Liz on her site but realised that it would be a lengthy entry, so I decided to expand my reply into an entry on my site, right here.

What are WordPress and The GPL?

It’s probable, if you’re a seasoned internet user, that you’ve heard of WordPress. If you haven’t, it’s web software you can use to create a beautiful website or blog. It’s what’s in use right here on this website.

You may not have heard of the GPL, or, perhaps you have heard of it but didn’t read it because it looks like some boring terms and conditions that come with stuff you’ve bought or downloaded. The GPL is:

…a free, copyleft license for software and other kinds of works.

The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program–to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. 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 them 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 prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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.

An important part of the above quote is the one referring to free software meaning freedom and not price. This is from WikiPedia:

With the advent of the free software movement, license schemes were created to give developers more freedom in terms of code sharing, commonly called open source or FOSS. As the English adjective “free” does not distinguish between “for zero price” and “liberty”, the phrases “free as in beer” (gratis, freeware) and “free as in speech” (libre, open source) were adopted.

These phrases have become common, along with gratis and libre, in the software development and computer law fields for encapsulating this distinction.

There’s a good video from The Free Software Foundation that explains the GPL and Free Software:

www.youtube.com/watch?v=te1Vbt-BGMA

Then of course, there’s Stephen Fry’s video wishing GNU a Happy 25th birthday:

www.youtube.com/watch?v=cT7Vl4UpCEM

So what we have in the GPL and Free Software is an ideology that promotes sharing, social interaction and advancement in an open and free way. You are entitled to use, modify and build upon the work of others and the only thing asked of you is that anything you produce that derives from the free software, adopts the same licence. You are given freedom, you should pass-on freedom.

So where’s the problem, how can anyone not like this concept?

The GPL and Business

Chris Pearson, the aforementioned Thesis author, is an apparently successful WordPress developer. His Thesis theme is popular and sells. You buy Thesis and you get a slick addition to WordPress together with support in the form of tutorials and a web based community. The problem is, Pearson doesn’t release Thesis under the GPL in direct violation of the GPL itself. He builds upon WordPress therefore Thesis automatically must adopt the GPL. Pearson is entitled to sell you his theme BUT IT MUST be GPL. He could divide his theme into two parts, one that contains code derived from or built upon WordPress and then one part that contains files that don’t, such as CSS files or Javascript. He doesn’t, in fact, he adds his own terms of service:

Use or distribution of Thesis in violation of the terms and conditions of membership contained in this document will result in termination of your membership, without refund. Also, please be civil and considerate when making use of the support forums, as bad behavior is also grounds for termination of your membership.

So Pearson is freely taking the work of others whose expressed wish is that he can have it, use it and build on it PROVIDED his derivative work adopts the same licence.

How wonderful and how altruistic of the large numbers of WordPress developers to do such a thing. What does Pearson do? He decides to ignore them and apply his own licensing terms with a view to making money. I personally find that disgusting.

Pearson can bleat all he wants about how he wants a payout for all his time and effort but he misses the point that’s sat there right in front of him. He can make money from the GPL through his support and website but he simply cannot break the GPL licence for his own gain. The GPL is there to protect people’s freedoms and he’s trampling all over them. Pearson will argue that the GPL doesn’t apply to Thesis because it’s a separate entity from WordPress. Well how can it be? As Mat Mullenweg says, WordPress without Thesis (using its default 2010 GPL theme), you have something to look at. Thesis without WordPress, nothing. So there’s no argument, Thesis absolutely relies on WordPress and is therefore derived from it and inherits the GPL.

But what does Mat Mullenweg do in response in the interview at Mixergy and Pearson’s blindness over the issue? He asks Pearson to join the WordPress family. He says, in a tongue-in-cheek way that he’ll use Thesis if it becomes GPL. He asks Pearson to take a leap of faith and dismantle the restrictive walls surrounding his work and embrace the open community. I don’t think he will and he should be ashamed.

I already respected Mat Mullenweg prior to listening to the Mixergy interview but I now admire him immeasurably. He has this wonderful software that millions of people use and he has the vision to allow it to be GPL. How can anyone criticise Mat for his adoption and use of the GPL. He and others are giving you their work, free of charge. Let’s put that in bold in case you didn’t see it, FREE OF CHARGE

Me

I suppose this is a good place for me to talk about how I came to be such a staunch supporter of the GPL and Free Software.

When I started regularly using computers, my chosen platform of choice was Amiga. It was by accident because some software that I wanted to use was based on that platform and so that’s the direction I took. The Amiga OS was/is a proprietary system, meaning that it has a closed restrictive licence. Nevertheless, in those days I was blissfully unaware of the GPL and since the Amiga was a platform running in direct competition to the future behemoth of the Microsoft hegemony, it suited me. I even became one of the founders of an Amiga User group and I wrote some small pieces of software for the platform.

When the future of Amiga began to look uncertain I clung onto the hope that it would somehow undergo a renewal and be developed into a realistic and viable alternative to Windows. It didn’t happen. It was around this time that I decided to look at Linux. I grabbed a copy off a magazine cover disk and installed the software to my PC. It was a crazy new world and I was a little bit bedazzled. Fortunately, I’m quite at home on the command line and so changing over to the Linux shell was an easy transition for me.

One of the first things I wanted to install was a FTP server so that I could transfer files between machines. I’d used a some proprietary licensed FTP software on my Amiga so I began searching for a Linux one. It was a little confusing and my search results didn’t help. Then I wondered if perhaps, somehow, there was already a client in my newly installed Linux box. I opened a terminal and typed “ftp localhost”. I was instantly logged into my own machine because it was already running a FTP server out of the box. I really was gobsmacked. The software that I was looking to pay for was already there, and it was free. It was GPL.

Now this is going to sound a bit silly, but from that moment on my outlook on life has changed. The fact that people are prepared to effectively give away their work for the benefit of the community at large did and still does blow my mind. I’d love to be able to release my own software in a similar way but I’m not a programmer. So what I do is help out in other ways. I encourage people to use Free software, I answer question from Free software users and I go out of my way to help them.

This way of thinking, this ideology has stirred something in me that I didn’t know was there. The very core of who I am these days is centred around community, helping people and sharing. It’s called socialism. It’s the reason I feel very passionate about protecting freedom. It’s the reason I hate the big guys hitting on the little guys. It’s the reason I despise the bankers bonus culture. It’s the reason I’ve decided to join a political party with it’s roots in socialism. It’s the reason I pound the streets of Leeds shoving leaflets into people’s letterboxes, without being paid to do it. It’s the reason I will stop and help someone when others will drive past. It’s the reason why I’ll let others go first. It’s the reason I consider myself to be a better person than I was in my youth.

It’s not about me, me me. It’s about us.

There’s a Bantu word: Ubuntu. You may know it as a Linux Distribution . That distribution is so called because of the meaning of Ubuntu. Nelson Mandela explained Ubuntu as follows:

A traveler through a country would stop at a village and he didn’t have to ask for food or for water. Once he stops, the people give him food, entertain him. That is one aspect of Ubuntu but it will have various aspects. Ubuntu does not mean that people should not enrich themselves. The question therefore is: Are you going to do so in order to enable the community around you to be able to improve?

That’s why I love and fiercely defend the GPL, Free Software, GNU and Linux. It’s because I am what I am because of who we all are.

Richard Stallman

It’s worth pointing out that the GPL exists because of Richard Stallman (RMS). The hacker (and that’s not a bad thing) culture in which he existed promoted sharing and openness. When he was denied access to source code to try and fix something, the result was the start of his crusade for Free Software.

Liz Jamieson

I’m not singling out Liz here, I’m actually just answering her blog-post within my blog-post. I quite like Liz and although I’ve never conversed with him her husband Russell seems like an OK guy.

Firstly Liz asks:

We built a free GPL compliant WordPress plugin and because we have a high adherence to quality and service, it takes a lot of effort in support and development time. I don’t mind that but I do want to make a paid version of it that protects my time investment in the overall offering. Given that I willingly give the free plugin away for free along with support for said plugin, how can I get paid for the extra effort I place into the paid features? How do I do that? It’s not obvious to me at all – I see Chris’s point of view. I’m not trying to be awkward here – I really want to know the answer. Maybe someone who can pay their mortgage based on their work (non client based please) with wholly compliant GPL plugins and themes could help me out here.

I understand your point, I really do. The thing is though, your plugin (which I like btw!) inherits the GPL. So you can charge for it but you must make the source available for it. If you’re not happy with that, then you should concentrate on writing plugins for non-GPL software. It’s cold and harsh, but it really is as simple as that.

A point that I often repeat is that you have chosen the leader in the blogging world: WordPress, because it’s exactly that. It has the largest userbase. So it’s a bigger market for you. WordPress however, is given away free of charge because it comes without restriction. Yet you want to restrict the use of a plugin for it? That’s selfish isn’t it? You’re happy to accept the WordPress licence allowing you to do what you want with the software, but you want to then disregard it for your own profit? You know that can’t be right.

If this means that it effects you as a small business, because no-one is going to pay for support, well again, it’s harsh but it’s a bullet you have to bite. The bullet was fired your way when you started developing for WordPress. Software built on sharing and co-operation.

I think that writing something that merely sits on top of something else doesn’t make it derivative. Thesis for me is not a derivative work in common sense terms, only in GPL terms.

Now I really don’t understand this. Thesis without WordPress is nothing. WordPress without Thesis is a blogging platform. The GPL is there to protect the rights of the authors of WordPress. If Pearson profits because of Thesis, that profit is DIRECTLY linked to Thesis running on WordPress. Of course, that profit is fine if someone wants to pay, but the price Pearson MUST pay is to release Thesis as GPL. Now that’s a sensible business model isn’t it. What’s the alternative, enforce a restrictive licence on WordPress thereby requiring all its users to pay a fee for its use? The blogging world would collapse overnight!

If I go my local supermarket (Waitrose, let’s say it’s a GPL supermarket) and buy a GPL cake, then take it home, cover it in icing and stick a couple of icing sugar roses on it then enter it into a cake competition, which I then win, people might say I cheated (analogy for breaking rules of the GPL). But under the GPL, if I go to Waitrose and buy other GPL products such as flour, eggs, sugar, and some other stuff, take them home, make a cake and enter the result into a cake competition and win it, then that’s also not OK. Because it’s still a derivative cake.

GPL supporters will say that’s right – so base your cake on non-GPL supermarket products if that’s how you feel. But I like shopping at Waitrose.

Your analogy is flawed here Liz. In the first case, your purchased GPL cake is forked by you when you ice it and decorate it. If you then win a cake competition, good for you! Everyone can see what you did. Are you really going to try and pass it off as completely your own? The cake world would out you and you’d just look silly.

In your second case I don’t even see a problem? You use GPL products to make another product which then wins you a competition, what’s wrong with that?

I think the problem is that cakes and ingredients are tangible things. Software isn’t. What you look at are just pixels on a screen. It doesn’t exist in the real world. What does exist is service. A service to support those ethereal pixels and bytes is tangible and therefore chargeable.

So this is what we all have to do? Create free and pro versions of plugins that we can offer to those who want to learn from and re-use the code, but keep the tricky bits on remote servers so that we can be paid and so provide quality updates and support to our users.

Provided the tricky bits don’t inherit the GPL, that’s fine. It’s not my cup of tea since I believe that all software should be free but in this instance we’re talking about the GPL.

Grokking Free Software and the GPL

In my opinion, developers who want to release software derived from or forked from GPL licensed work don’t actually grok the whole free software ethos. They see large userbases such as the one surrounding WordPress and simply want to cash-in. It’s understandable. However, they fail to realise the reason why the GPL exists and choose to ignore it for their own reward.

I don’t have a solution, other than to recommend a paid-support based service. Keep your software free and open, bill for your service man-hours. If it doesn’t suit your needs, you need to develop for another platform.

What is SteadyOffload?

SteadyOffload is a content delivery service. Here’s how the service describes itself:

SteadyOffload is an innovative service designed to reduce the load of your web server seamlessly. It enables you to offload all kinds of static web content – images, documents, movies, presentations, software downloads, you name it. The content you offload remains stored on your server while synchronized copies are delivered from us. It all happens transparently – all you have to do is point the files to offload, the rest is done by our cachebot.

So, what’s all that about then. Well, in all honesty if you visit the SteadyOffload site they do a good job of explaining what they are all about. In a nutshell they save your server from excessive work by serving up static files held on the SteadyOffload servers. It works much in the way that Amazon S3 does but with hardly any hassle at all. You simply upload your static image, document or whatever file and it gets mirrored and then subsequently served by the SteadyOffload server. All your own server need do is then serve up the dynamic content at a fraction of the server load.

So How Does it Work?

In order for the SteadyOffload integration to start working you obviously need to sign up for an account. New signups get 5GB of bandwidth free. Once that’s expired it works on a pay as you go basis but the fees are very competitive compared to other more well known delivery services. Once you have your account up and running you simply have to put a small piece of HTML code in pages that show static content. Here’s the code:


script type="text/javascript" src="http://steadyoffload.com/serve/name of script.js">/script


Then, by using custom tags, your static content is offloaded to SteadyOffload and your server can take a breather. Here’s an example custom tag:


img srcx="/home/www/site/example.jpg" /


Note the custom scrx tag

There’s also a funky plugin for WordPress Users that takes care of all the business for you. Grab it from here: WP-Offload.

An obvious benefit of SteadyOffload is that whilst the files are served remotely, if you cancel your account, your original files are still in place and ready to be served once again by your server, which probably won’t thank you too much for all the work you’re giving it back.

Control Panel

When you have your SteadyOffload setup running sweetly, you can monitor what’s being offloaded by visiting the Control Panel. Here you can set URL Filters to ensure no-one is stealing your bandwidth, monitor offloaded files and keep tabs on your subscription.

Added 28/5/09

I found a really useful Video at Google produced by SteadyOffload themselves that shows how simple it is to use the Control Panel. It also shows something that I neglected to mention and that’s dynamic image manipulation by using the “xmanip” tag. The video is here.

And so…

I think SteadyOffload is a great service that deserves support and can provide obvious performance benefits for your site. It’s simple to set up, free to trial and cheap once you use up your free bandwidth. Once I start paying (and yes, I haven’t used up my freebies yet) then I’ll make an effort to produce some stats and figures to show just how cheapo it really is.

Give it a go!

NB. Nearly forgot, I recently Tweeted on Twitter about SteadyOffload since I stupidly misplaced my password. As far as I can tell I was the first person to tweet about it. Ever. Unreal! My Original Tweet

Automated Lifestream Blog Software

Sweetcron is software that pulls in the feeds offered by other sites, ideally your own or your own accounts. In particular it’s an excellent tool to aggregate all your social networking updates, uploaded images, loved songs, bookmarked links, favourited videos etc etc. If you use a site and you have a presence there, if that site has an RSS feed of your activities, Sweetcron can deal with it.

Having a site pull in a boat load of stuff is cool, but what’s the point. Well, you can serve up those feeds in any way you want and each individual feed item can display as much or as little information about itself as you want, provided of course that the information is in the feed in the first place. My personal preference is for bite sized chunks or excerpts which is probably the way most people go.

The really cool thing about it all is that once you’ve decided which feeds to import, figured out how you want them to be displayed and tweaked things a little, you can pretty much walk away and let it get on with things all on its own. If you haven’t got access to a cron utility, which is how the thing is automated, Sweetcron has a built in pseudo cron to update every 30 minutes.

So you end up with an automated sort-of-blog that records your activities. If you can’t be bothered blogging for a while but nevertheless continue tweeting or other such funky things, your legions of readers can see what you’re up to. If you still don’t get it, no worries, there’s plenty more other things to get excited about. The bottom line is, I think it’s fun.

Blogging

I mentioned that I nearly abandoned WordPress completely when I found Sweetcron. Well; as well as having all the super cool feed capabilities, Sweetcron has a built-in blogging feature. You can either have the blog posts feature amongst all the other items or even have them displayed more prominently, as in WordPress et al. The blogging facility isn’t as complex as WordPress’ but to be honest I don’t think it’s meant to be. It’s just there if you want it and it’s more than adequate for the task. I suppose you could say that you use WordPress for blogging but hey it can import RSS if you want, you can use Sweetcron as an RSS aggregator but hey it can do blogging if you want. Easy.

I’ve decided that the fun thing would be to interlink the two. Sweetcron takes the WordPress feed and WordPress can be made to list the Sweetcron latest items. Your blog then doesn’t get all cluttered and your lifestream just becomes that, a record of your day to day interaction with the interweb, all on its lonesome. Sweet.

Themes

Just as in WordPress, Sweetcron is themeable. OK there aren’t kazillions of themes out there but it’s relatively easy to get build your own theme based on the default ones that come supplied with the software or one of the third party themes available.

I’m currently using the SocialCubes Theme by Derek Punsalan. Tweaked a bit as usual by me. As always I’m intending to build my own theme from scratch but hey, I’m a slow worker remember!

I found a couple of pages that list Sweetcron themes:

• Sweetcron Themes
• 25 of the best sweetcron powered lifestreams

So Let it Roll

So there you go, my Sweetcron lifestream is up and running and there for all to see. If you fancy one yourself and want some help, you can join the Sweetcron Google Group or just contact me and I’ll be glad to help out where I can.

Sweetcron and Nginx

I use the alternative (to Apache) web server Nginx to run my sites. It took me a while to figure out how to get Sweetcron to work happily under Nginx as there’s some rewriting to be done. After ages I finally figured out a way to make it work. The details are below after the read more:

Server Config:

# ———-

server {

location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include /etc/nginx/fastcgi_params;
fastcgi_param SCRIPT_FILENAME /var/www/foo.bar.com/index.php;
}
}

#———————-

The /etc/nginx/fastcgi_params are unchanged from those that work for WordPress etc:

#———————-

fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;

#—————————–

In system/application/config/config.php I made sure this line read like so:

#——————————

$config['uri_protocol'] = "REQUEST_URI";


#——————————

Hope that helps someone out.
