Rotten to the (Open) Core?

Open core, Open core,  more Open core… the debate goes on and on, with Monty the latest to weigh in.

When you get down to it this is a fight over branding – which is why the issue is so important to the OSI folks (who are all about the brand). I don’t actually care that much how SugarCRM, Jahia, Alfresco et al make the software they sell to their customers. As a customer I’m asking a whole different set of questions to “is this product open source?” I want to know how good the service and support is, how good the product is, and above all, does it solve the problem I have at a price point I’m comfortable with. The license doesn’t enter into consideration.

So if that’s the case (and I believe it is), why the fighting? Because of the Open Source brand, and all the warm-and-fuzzies that procures. “Open solutions” are the flavour of the decade, and as a small ISV building a global brand, being known as Open Source is a positive marketing attribute. The only problem is that the warm-and-fuzzies implied by Open source – freedom to change supplier or improve the software, freedom to try the software before purchasing, the existence of a diverse community of people with knowledge, skills and willingness to help a user in difficulty – don’s exist in the Open Core world. The problem is that for the most part, the Open Core which you can obtain under the OSI-approved license is not that useful.

Yesterday on Twitter, I said “Open Core is annoying because the “open core” bit is pretty much useless. It doesn’t do exactly what it says on the tin.”

Now, I wasn’t expecting this to be particularly controversial, but I got some push-back on this. Dan Fabulich replied “Ridiculous. Like the free version of MySQL is useless?” Which leads me to think of Inigo Montoya on the top of the Cliffs on MoherInsanity turning to Vizzini and saying “You keep using that word. I do not think it means what you think it means.”

With all this talk of Open Core, clearly some confusion has crept in. Perhaps it’s on my part. So allow me to elaborate what I understand by “Open Core”.

First, companies can’t be Open Core. Products are Open Core. So whereas Monty considers that from 2006 on, MySQL was not an “Open Source company”, I would contend that MySQL Server has always been, and continues to be, Free Software, and an Open Source product. That is, not Open Core.

Open Core for me means you provide a free software product, improve it, and don’t release the improvements under the free software licence. In my mind, Mac OS X is not “Open Core” just because it’s based on the NetBSD kernel, it is proprietary software.

Perhaps it would be useful to give some examples of what is Open Core:

• Jahia is Open Core – significant features and stabilisation work are present in the Enterprise Edition are not available at all in the Community Edition
• SugarCRM is obviously Open Core. Key features related to reporting, workflow, administration and more are only present in the commercial editions
• JasperSoft BI Suite is Open Core. Lots of useful features are only available to people buying the product.

The key here is that support contracts and extra features are only available if you also pay licensing fees. To take the oft-cited example of InnoDB hot back-up tool for MySQL, you can purchase this and use it with the GPL licensed MySQL Server.

This is why I say that Open Core products “don’t do exactly what it says on the tin” – the features you see advertised on the project’s website are not available to you along with software freedom.

I have talked to companies who deliberately avoid adding “spit & polish” to the community edition to encourage people to trade up for things like better documentation, attractive templates and easy installation – and don’t provide an easy way for the community edition users to share their own work. Other products have an open source engine that doesn’t do much except sit there, and all useful functionality is available as paid modules. Yes, a persistent, skilled, patient developer can take the Open Source version of the product and make it do something useful. For the most part, however, if you want to actually use the software without becoming an expert in its internals, you’ll need some of the commercial upgrades.

There is another name for this which is even more pejorative, Crippleware. Deliberately hobbled software. And that’s what I think gets people riled up – if you’re releasing something as free software, then there should at least be the pretence that you are giving the community the opportunity to fend for itself – even if that is by providing an “unofficial” git tree where the community can code up GPL features competing with your commercial offering, or a nice forum for people to share templates, themes and extensions and fend for themselves. But what gets people riled is hearing a company call themselves “an Open Source company” when most of the users of their “open source” product do not have software freedom. It’s disingenuous, and it is indeed brand dilution.

That said, let me repeat – I have no problem with companies doing this. I have no problem with them advertising their GPL-licensed stuff as Open Source. I would just like to see more of these companies providing a little bit of independence and autonomy to their user community. But then, that’s potentially not in their long-term interest – even if it is difficult to imagine a situation where the community-maintained version outstrips the “Enterprise” edition in features and stability.

GNOME Training confirmed!

A few days ago, I took the risk of setting off alarm bells on the GNOME developer training sessions planned for GUADEC this year. It was a risk, and comments from the naysayers reminded me that it’s easier to do nothing than it is to take a risk. I’m happy to say that the risk paid off.

Thanks to all who spread the word, a couple of prospects I was aware of confirmed their presence on the course, and I received a new group booking. The training is now feasible, and we are confirming that it will happen. There is still room on the course, and I expect to sell a few more spots in the coming days.

I did get one interesting suggestion in a Twitter reply to the announcement, and I’ve adopted it. If you are interested in attending one or two of the modules (say, community processes and the GNOME platform overview, but not the practical session or Linux developer tools), you can do so for the much lower price of €400 per module and €750 for two modules, not including a GUADEC registration.

Anyone who would like to avail of this offer, please contact me, and we will take care of getting you signed up.

Thank you all for your help and support!

Heathers

No, not the film.

While I’ve been back in Ireland it’s been impossible to avoid “Discover Ireland” promoting the country as a tourist destination for locals, with ads backed by an infectiously catchy tune.

I’d never heard the group before, so I went hunting and found Heathers, an Irish duet of teenage girls who seem just a little shy, but when they start singing they belt it out. Very simple – guitar + +2 female voices, with an atypical sound and a heavy Irish accent. They’re pretty great. The joys of the interweb and youth who thinks differently about copyright – there is *lots* of live material from these girls on youtube. They’ve already been touring the US and I suspect that they will make a name for themselves. Well worth discovering.

GNOME Developer Training in danger

The take-up on the GNOME Developer Training sessions at GUADEC (pdf brochure) has been below expectations. Without going into the details, we’re in a situation where running the training would cost the foundation and the organisers more money than canceling.

If we have not had a number of people sign up for the training by Wednesday evening, we will unfortunately be in the situation where we will have to cancel the session. The GUADEC organisers sign the final contracts with the university for room reservations on July 1st, and that will increase our costs substantially, so that is our deadline for viability.

I hesitated for a long time before writing this blog. It’s never nice to have to admit that something you thought was a good idea, that you put together and made a reality, might not work out.

Many people have, over the years, said that the lack of training options was a major flaw with GNOME. With this training offering, we gave people what they were asking for, with a two day training course plus the flagship GNOME conference for less than you would pay to attend another technical conference. If we cancel this training session, there will likely not be another. The credibility of the foundation (and, I suppose, my credibility) will take a hit.

I decided to let people know in advance that the session is likely to be canceled, to have a chance to stop that from happening. I have confidence that the GNOME community can come to the rescue here, in some sense.

I am sure that there is interest out there. Perhaps people have not yet gotten budget commitments to send developers along, but that they’re still working on it. Perhaps there are people who really should know about the training who don’t yet, because I haven’t managed to get in touch with them. Perhaps a couple of people were planning on signing up, but haven’t gotten around to it yet.

If you are in one of these categories, please get in contact with me soon. If you know someone who would benefit from the training, please let them know, and point them to the brochure and web page. If I have a relatively small number of commitments to attend by Thursday, the training will go ahead.

Thanks everyone for your help and support – I will keep you posted to any new developments.

Sabotage and free software

Who knew that educating people in simple sabotage (defined as sabotage not requiring in-depth training or materials) could have so much in common with communicating free software values? I read the OSS Simple Sabotage Field Manual (pdf) which has been doing the rounds of management and security blogs recently, and one article on “motivating saboteurs” caught my eye enough to share:

Personal Motives

• The ordinary citizen very probably has no immediate personal motive for committing simple sabotage. Instead, he must be made to anticipate indirect personal gain, such as might come with enemy evacuation or destruction of the ruling gov­ernment group. Gains should be stated as specifically as possible for the area addressed: simple sabotage will hasten the day when Commissioner X and his deputies Y and Z will be thrown out, when particu­larly obnoxious decrees and restrictions will be abolished, when food will arrive, and so on. Abstract verbalizations about personal liberty, freedom of the press, and so on, will not be convincing in most parts of the world. In many areas they will not even be comprehensible.
• Since the effect of his own acts is limited, the saboteur may become discouraged unless he feels that he is a member of a large, though unseen, group of saboteurs operating against the enemy or the government of his own country and elsewhere. This can be conveyed indirectly: suggestions which he reads and hears can include observations that a particular technique has been successful in this or that district. Even if the technique is not applicable to his surroundings, another’s success will encourage him to attempt similar acts. It also can be conveyed directly: statements praising the effectiveness of simple sabotage can be contrived which will be pub­lished by white radio, freedom stations, and the sub­versive press. Estimates of the proportion of the population engaged in sabotage can be disseminated. Instances of successful sabotage already are being broadcast by white radio and freedom stations, and this should be continued and expanded where com­patible with security.
• More important than (a) or (b) would be to create a situation in which the citizen-saboteur acquires a sense of responsibility and begins to educate others in simple sabotage.

Now doesn’t that sound familiar? Trying to convince people that free software is good for them because of the freedom doesn’t work directly – you need to tie the values of that freedom to something which is useful to them on a personal level.

“You get security fixes better because people can read the code”, “You have a wide range of support options for Linux because it’s free software and anyone can understand it”, “Sun may have been bought by Oracle, but you can continue to use the same products because anyone can modify the code, so others have taken up the maintenance, support and development burden”, and so on.

Providing (custom tailored) concrete benefits, which comes from freedom is the way to motivate people to value that freedom.

In addition, the point on motivation struck a cord – you need to make people feel like they belong, that their work means something, that they’re not alone and their effort counts, or they will become discouraged. A major job in any project is to make everyone feel like they’re driving towards a goal they have personally bought into.

Finally, you will only have succeeded when you have sufficiently empowered a saboteur to the point where they become an advocate themselves, and start training others in the fine arts – and this is a major challenge for free software projects too, where we often see people with willingness to do stuff, and have some difficulty getting them to the point where they have assimilated the project culture and are recruiting and empowering new contributors.

For those who haven’t read it yet, the document is well worth a look, especially the section on “General Interference with Organisations and Production”, which reads like a litany of common anti-patterns present in most large organisations; and if you never knew how to start a fire in a warehouse using a slow fuse made out of rope and grease, here’s your chance to find out.

Last chance for early bird rate for GNOME training

Registration for the GNOME Developer Training courses at GUADEC is still open on the GUADEC registration site – and the early bird rate of €1200 is available for all orders received until next Tuesday June 15th. So if you’ve been hesitating or delaying signing up, the time is now!

As a reminder of what’s included in the package, you will get lunch and refreshments both days of the training course, a full professional registration to GUADEC worth €250, and printed materials related to the course to take home with you and spread the knowledge, and two full days of intense Lunix development training with a focus on GNOME. There are four half-day modules, covering Linux development, testing and debugging tools, the social side of contributing to free software projects, an overview of the GNOME and freedesktop.org platform and a hands-on workshop where you get to put what you learn into practice.

this will be a great opportunity to give a boost to your entire team by learning developer tips & tricks on being a productive Linux developer, learning tools and tips to improve performance and memory usage of your applications, and how to get your code upstream more efficiently & reduce maintenance costs.

Registration is open, and we still have a few places left!

GNOME Developer Training at GUADEC

I’m delighted to announce the availability of GNOME Developer Training at GUADEC this year. It’s been brewing for a while, but you can now register for the training sessions on the GUADEC website.

Fernando Herrera, Claudio Saavedra, Alberto Garcia and myself will be running the two-day course, covering the basics of a Linux development environment and developer tools, the GNOME stack, including freedesktop.org components, and the social aspects of working with a free software project, being a good community citizen, getting your code upstream, and gaining influence in projects you work with.

The developer tools section will go beyond getting you compiling the software to also present mobile development environments, and the tools you can use to profile your apps, or diagnose I/O or memory issues, dealing with the vast majority of performance issues developers encounter.

This is the first time I have seen a training course which treats the soft science of working with free software communities, and given the number of times that people working in companies have told me that they need help in this area, I believe that this is satisfying a real need.

We are keeping the numbers down to ensure that the highest quality training & individual attention is provided – only 20 places are available. The pricing for the training course is very competitive for this type of course – €1500 per person, including training, meals and printed training materials, and a professional registration to GUADEC, worth €250.

If you register before June 15th, you can even get an additional discount – the early bird registration price is only €1200 per person.

I’m really excited about this, and I hope others will be too. This is the first time that we will have done training like this in conjunction with GUADEC, and I really hope that this will bring some new developers to the conference for the week, as well as being a valuable addition to the GUADEC event.

Jet-lag tips and tricks

During my recent adventures in San Francisco, I told a number of people about my jet-lag “cure”, and they found it sufficiently interesting I thought I would share.

On trans-Atlantic flights, you typically take off late morning and arrive early afternoon  when traveling East to West, or you take off in the afternoon & land in the early morning when traveling West to East. There are two steps to dealing with major (>= 6 hours time-zone difference) jet-lag: what you do in the plane, and what you do when you arrive.

For me, when I’m traveling East to West, I don’t sleep much on the plane. I watch movies, get up & walk around, chat to the other people hanging around outside the toilets, read – whatever helps pass the time. This means that when I arrive at my destination, I’m tired – my body thinks that it’s late night and I’ve been awake all day. But in reality, it’s 2pm.

By the time you get out of the airport, get to your hotel and check in, it’s probably between 2pm and 4pm. If you go to sleep now, the chances are that you will sleep for several hours, then go out to eat a late dinner, and have difficulty getting to sleep for the night, resulting in tiredness early the following day. This is the vicious circle of jet-lag.

To break the cycle, here’s where my cure kicks in: get out of your hotel. Your body uses sunlight to set its biological clock, so by getting out in the daylight, you are helping your body to adjust to the new day and night pattern. Getting outside during the day suppresses the natural production of melatonin, which helps put you to sleep. It also stimulates the production of vitamin D, helping combat illness (another consequence of jet-lag).

The absolute best way to get out and get over jet-lag is to get some exercise. Go on a cycling tour of the city, or go running. Exercise stimulates the production of endorphines, making you feel good, and more importantly, after exercise you typically do not want to go to sleep. And a few hours later, when you do go to sleep, you sleep more soundly.

If you do an hour or two of outdoor exercise after arriving at your destination, then go back to your hotel and shower/bathe, go out for a bite around 7pm, and then get to bed at an early but reasonable 10pm, you should be able to have a good night’s sleep, and function all day the day after. I typically wake up very early the first couple of mornings when I travel to the States – which gives me an opportunity to (you guessed it) go for an early morning jog before getting ready to go where I have to be.

When traveling from West to East, the problem is similar, but the lag is in the other direction – you may have a hard time waking your brain in the morning when you travel 6 or more hours back in time.

The same trick works. Avoid excessive sleep in the plane – a couple of hours nap is about all I ever manage overnight on these flights. When you arrive, get outside and moving about for the afternoon. I love to go with the kids to the park when I come back from trips and run them (and myself) ragged with a football, or go for a walk with the family – anything to get us out of the house. To help me get to sleep, as well as skipping most of the previous night in the plane, I take a melatonin pill (purchased in Safeways while in the US, not on sale in Europe for some reason) to help me to get to sleep at the right time. And the following morning, when I have the most difficulty waking up my brain, I force myself with difficulty to put on a pair of trainers and go for a 45 minute jog.

And that’s all there is to it! Typically, the day I arrive I suffer, the day after I can function, but am not 100%, and the the day after that, I am fully adjusted to my new time zone.

Does anyone have any other hints & tips to overcome jet-lag? Comments open!

Comparing Maemo & Ubuntu

While I’ve occasionally been critical of Ubuntu as a project, it is a distribution with very open processes, for the most part.

I’d like to compare the experience of a casual Ubuntu user, an engaged Ubuntu user, an Ubuntu developer, and an upstream application developer to the equivalent MeeGo or Maemo experiences.

The casual Ubuntu user gets regular stable updates on a predictable schedule, with long-term supported versions less frequently, but still on a predictable schedule. Stability, releases, this user doesn’t want to know what happens behind the scene, he wants to get software when it’s “done”.

The engaged Ubuntu user can activate an unstable development distribution, and see the work going in as it’s being done! He updates daily, gets the latest and greatest, and occasionally stuff doesn’t work, but he doesn’t mind. The information how to do this isn’t on page one of ubuntu.com, but it’s there, and engaged users tell each other about it.

The Ubuntu developer can participate in the creation of the process by packaging his favourite software, pushing it through a public (although occasionally real-time & in-person) process for inclusion in the holy grail – default installation, or presence on the install CD. He can take care of packaging, shepherd the package through QA, ensure that problems get reported upstream and in general ensure that his package is a good Ubuntu citizen. Even if he doesn’t get the package in the default install, which is quite tough, he can follow public community processes to have it available in the Universe, available to every single Ubuntu user through a simple search of available applications.

The upstream developer doesn’t really care that much about Ubuntu. He develops his application, sees bug reports coming in from users & developers & downstream packagers. He adds features, and concentrates on what he loves best – coding the best app he can.

Now, compare that experience to Maemo, to see how we compare:

For the casual user, not much changes. He gets the software on a device, when it’s “done” (and the definition of done is considerably different for a phone than a PC distribution).

For the engaged user, who wants to follow the bleeding edge, the story gets murkier. In the Maemo world, hardware and software releases have been closely related. Without a Beagleboard or a prototype N900, Fremantle wouldn’t have been very useful. But even operating system updates like the upcoming long awaited PR1.2 are not packaged and prepared in public, so even existing N900 owners can’t follow along with the cutting edge.

There is a promise that the first release of MeeGo will work well on the N900, so potentially there is an opportunity for the engaged MeeGo user to follow along with unstable development – on condition that, like the engaged Ubuntu developer, they’re prepared for the occasional bricking & reflash. But the UX software for MeeGo is being prepared for release – we are told that some closed components are being opened, some others are not ready for release yet. So it is not (yet) possible for an engaged MeeGo or Maemo user to follow along & install a base alpha or beta distribution and update or reflash regularly.

For packagers who would like to propose their software for inclusion in the default repository, or even on the default install, of MeeGo or Maemo, there is not (yet) a clear path to get involved in the process. I could start working on a Maemo port of QuteCom, Shotwell or some other software, but if I did, there’s no way for me to get that software included by default. The current Extras/Extras-testing policy of Maemo has been heavily criticised by some developers – so it might not even be easy for me to make my software available to a large number of Maemo issues.

The upstream developer experience doesn’t change that much. Upstream developers still shouldn’t care about what packagers are doing, and should be concentrating on making the best apps possible. But for major parts of the MeeGo platform, namely the UX projects, the upstream and downstream will be hard to separate. As an upstream developer, I care about being able to follow commits, read Changelogs, do code review, develop and propose features, fix bugs and so on, in the open. For unrelated upstream projects, things also change – due to form factor and UX guidelines, the developer really needs to do a tailor-made UI for MeeGo or Maemo, requiring effort not being spent on features. And because you’re doing embedded development, your development environment becomes that much more complicated, with emulators and cross compilers and SDKs.

The embedded world is a special place, a lot of things change from desktop development, and some of those changes come with the territory. You’re going to have to work with a device emulator, and anything that requires a SIM card, the GPS, camera, accelerometer or any other hardware features, well, you’re going to have to wait for a device to make 100% sure those work. But we can certainly bear in mind the Ubuntu user experience(s) when we are designing the MeeGo community, and ensure that their experience is just as open.

That means open code, and more importantly open processes. It means an engaged user being able to use software that isn’t ready, a packager being able to propose software for inclusion in the OS and ensure its availability to all users of the distribution by following a well defined process, and a developer having a great experience helping to develop great applications.
