There are many things I like about Google+, but, beyond being yet another proprietary social networking service, something just doesn’t sit well with me about Google’s primary purpose. Comments by Brad Horowitz that Google+ will be connected to everything Google are a good example of what concerns me:
Google+ is Google itself. We’re extending it across all that we do — search, ads, Chrome, Android, Maps, YouTube — so that each of those services contributes to our understanding of who you are [emphasis added]
Maybe I’m naive or wrong, but it never seemed like the primary motivation behind Gmail was to sell more ads. It felt like an innovative email service that Google was able to monetize with relevant, contextual ads, not merely a means to improve Google’s ad business. But Google+ feels different. Google’s primary interest is to get access to more social information, not to create a better social networking service. Buzz or Google+ are just the means for Google to gather social data.
As Fred Wilson said with respect to Google+ as an identity service:
It begs the question of whom Google built this service for? You or them. And the answer to why you need to use your real name in the service is because they need you to.
Google is often pretty good at aligning its interests with that of its users. For example, the more useful their ads are to users, the better Google does. Or, the better your web browser is, the more you use the Internet, the more Google thrives. But with Google+, it feels like the desire for an identity data mining tool well precedes their desire to provide a useful social networking platform.
Google+ is not first and foremost “a place for friends” or a way for student life to find expression online. From Google’s hyper-engineer perspective, we are just things to be organized in the process of organization the world’s information. They’ve organized web sites, photos, maps, calendars, videos, books — now, they’re just organizing people.
Maybe Google+ is really no different from other Google services. Maybe I’m just different. I don’t want my relationships with other people, my identity, to be treated as ultimately just data to harvest, information to organize, inputs to a proprietary Google algorithm, a way to teach Google about me as some sort of data structure. Google+ seems to exist more for Google than it does for me.
I don’t want to be treated as just a thing to be organized.
A couple years ago, I would have said that network services and mobile computing were two new frontiers for software freedom, two new challenges, two new battles. But, despite some key differences, these two areas are so closely related and that I think we need a unified vision for addressing these as two parts of a whole.
Companies like Google have a unified vision. Look at Chrome or Android from Google’s perspective: the purpose of a mobile computer is simply to increase access to proprietary network services. These open source operating systems are designed to run proprietary applications and connect to proprietary network services. From Google’s perspective, mobile computing and network services go hand in hand — open source software is a way to increase the adoption of mobile computers complementing their proprietary network services. While Google’s goal is not software freedom, we should take note of how their strategy involves both mobile computing and network services together. We can’t effectively free one without freeing the other.
The free software movement needs a unified vision for network services and mobile computing. But what might that look like? StatusNet has an Android client, as does Libre.fm, but these are just more convenient ways to access network services from a mobile computer — not network services designed for mobile computing.
Look at the kinds of proprietary network services companies are developing for mobile computing. Google Latitude enables social location sharing, combining mobile positioning systems with online social networking. Last.fm’s mobile applications include some features for finding events based on your location. Google Goggles let’s you point the camera on your mobile computer at something and find information on that thing through Google’s search engine. Apple’s Facetime and Google+ Hangouts (not mobile quite yet…) are attempts to bring video chat to mobile and tablet computers. Social networking services like Facebook, Google+, and LinkedIn are focusing in on the mobile space as well.
What does free software have to offer? For location-based services, we have OpenStreetMap. StatusNet offers some location-sharing, but StatusNet for Android doesn’t seem to support this yet. Other than direct map programs, are there libre mobile applications making use of OpeenStreetMap? Could Libre.fm use mobile location data to highlight local free culture events? Regarding something like Google Goggles, are there many libre mobile applications can do something similar with, say, Wikipedia? (Mixare seems like a good example of this.) SIP and XMPP are great for video chat, but I’m not sure many users are aware of public XMPP or SIP services. How can we offer libre alternatives to Skype and Facetime on tablets? What kinds of opportunities are there for libre social networking services, like GNU Social or Diaspora, in mobile computing? What barriers are there to libre augmented reality or location-based services?
More importantly, beyond just emulating proprietary services, where might libre solutions offer new innovations? Where might free software have a distinct advantage, or something unique to offer? On desktop operating systems, the ability to easily distribute and repackage free software lent itself towards the development of package managers — applications that manage all your software installations and upgrades from one place, making it easy to find new software or keep your entire system up-to-date from one application. Meanwhile, on proprietary operating systems, you often have different update managers for each proprietary vendor. and upgrades often involve a purchase and don’t come as easily. Similarly, free software desktop operating systems provide much more desktop integration, as free software applications each contribute to a corpus of tools for the operating system, and distributions can customize software packages to make them work well together. On proprietary systems, each proprietary vendor tries to carve out their own space, and the distributor has limited options to customize software packages from other sources (or you end up with one company’s vision being ruthlessly enforced on any players in the ecosystem, as with Apple).
What kinds of advantages does free software have in developing a comprehensive approach to network services and mobile computing? Is it that libre solutions are often more distributed and less subject to surveillance or external control? That the user isn’t just a product for advertisers? I’m not sure yet myself, but this is something I think software freedom advocates need to consider more directly. Proprietary mobile computing offers convenient vertical integration with proprietary network services. What unique advantages does free software have at the intersection of mobile computing and network services?
Software freedom advocates need to think about network services and mobile computing together. If you take a look at the FreedomBox Foundation, for example, there are a lot of great ideas floating around about free network services… but there seems to be little mention of mobile computing. Yet, people are increasingly interacting with network services through their mobile and tablet computers, rather than just on their laptops. Bradley Kuhn offers another example. He never ceases to share excellent insights on software freedom for mobile computers and network services, but usually as two separate topics. For example, in a March 2010 post entitled Musings on Software Freedom for Mobile Devices, Kuhn writes:
We can take a page from Free Software history. From the early 1990s onward, fully free GNU/Linux systems succeeded as viable desktop and server systems because disparate groups of developers focused simultaneously on both operating systems and application software. We need that simultaneous diversity of improvement to actually compete with the fully proprietary alternatives, and to ensure that the “mostly FLOSS” systems of today are not the “barely FLOSS” systems of tomorrow. [emphasis added]
He’s absolutely right here, but network services form a third necessary category of software for success in the mobile space. In the same way that a libre desktop OS needs libre applications, a libre mobile OS needs libre network services. In a sense, to talk about software freedom on mobile computing without mentioning network services is like talking about building a free desktop operating system without mentioning the applications. And the interdependent relationship between mobile applications and network services is much more complex than application level software for a desktop OS.
It’s not just a question of which libre network services are missing, or which libre mobile applications are missing, but how libre mobile applications and network services can complement each other and work together. Success in one area depends on success in the other. We need to approach network services and mobile computing not just as two separate challenges, but as two parts of a whole, with a comprehensive vision and shared strategy. What might that look like?
I’m increasingly critical of network services — software that you use on someone else’s server to do your own computing. We rely on computers more and more for our work, social lives, civic engagement, health, education and leisure, and more and more that means relying on networking services rather than our own personal computers. There are serious trade-offs to living as a tenant online, rather than a property owner. I’ve been reconsidering the network services I use and rely on, especially in the shift to mobile computing.
The work of Autonomo.us has heavily influenced my thinking. Also of note is Stallman’s essay on software as a service (though he does more to identify the problems than recommend solutions). I essentially agree with the Franklin Street Statement from Autonomo.us. As a user of network services, I’ve narrowed it down to four major criteria to look for when deciding whether to trust a service on freedom and autonomy.
Note: This is more of a working list than an attempt at a formal definition. For example, I’m not sure that #3 and #4 should be required, even though I believe they are important. Feedback is welcome.
Free (libre) or open source software licenses designed for network services, like the GNU AGPL, help guarantee the software will respect users’ freedoms. The arguments for software freedom have been addressed at length elsewhere, but the freedom to run the software yourself is particularly relevant here since, unlike desktop software, you often have the choice of letting someone else run the software for you. Even if you don’t run the software on your own server, having the freedom to do so ensures that you can still run the service in the event that the service provider shuts down — a frequent concern with proprietary web startups after acquisition or failure. And, even if you can’t run the software yourself, with all four freedoms, chances are someone else will. The broader case for software freedom is made at length elsewhere.
Network services should respect users’ freedoms. LibreProjects.net has a good list of free web services and alternatives.
If users want to leave a service provider, can they take their data with them? Open standards are important. Open standards allow other software to read and understand your data. Open standards also allow you to mix the software you use on the client and server or across multiple devices more easily. Not only does this make migration more realistic, but it makes transitions smoother.
Google’s network services aren’t often free (libre) software, but Google does have a strong commitment to open standards and making your data easily available. I’ve used many Google services from non-Google clients: Gmail from Thunderbird, Evolution and Modest; Google Calendar from Lightning, Evolution, and my N900; Google Reader from Liferea and grr; Google Talk from Empathy, Pidgin, and my N900, etc. I’ve been able to switch my client-side software before changing the back-end. This makes it possible to transition to new services gradually, in smaller steps, with less disruption.
Facebook has a download feature, but it’s slow, and it just chucks all of your data into a giant zip file rather than putting it into formats that other software or services could understand. Facebook has also actively blocked services that export your data to other providers. Your data is available for download, but not in a very useful way.
Migrations are not always planned. On your own server, you have the master key. With a service provider, if you lose access to your account because it’s cracked or cancelled suddenly, will you also lose access to your data? Or will you have an up-to-date copy locally? Open standards often help make it possible to keep a local copy up-to-date, but this isn’t always the default way we use these services. A synchronization service will typically maintain a complete local copy of your data, but services intended to be accessed through the web often require additional client-side set up
on the user’s part to make this happen (e.g. using Thunderbird or OfflineIMAP to keep a local copy of your Gmail email, or using Google Sync to keep a local copy of your calendar and contacts). Or, the services may only offer data dumps as backup. Does a service let you keep a complete local copy of your data easily in your everyday usage? Even if you primarily use the web interface, setting up a desktop client for regular use can help maintain a local copy of your data without having to consciously download backups.
Lastly, public data that is intended to be shared should be available under a free and open licence. Identi.ca uses CC BY for public user data. Libre.fm focuses on freely licensed music. This gives control over public content to the community, rather than just the service provider.
Network services should let users control their data, using open standards to give users control of their personal data and free licences to give the community control over public data. Despite having a very mixed record on other criteria, Google is a good example of open standards done right. Free (libre) and open source tools are also usually good with open standards. Identi.ca is a good example of licensing public data freely.
My concern with privacy isn’t so much what a service provider’s policies are, but who has access to the data in the first place.
With the launch of Google+, I’ve been quite relieved that I’ve moved a lot of my important data out of Google over the past few years. It’s one thing for Google to have my email or my social graph or my documents, but the volume of data that would be in one place using all of Google’s services is astounding. Google is generally a well-meaning company, but I wouldn’t want any single organization to have everything that Google might have: my email (love letters, job applications…), address book (contacts and their private information), documents (budget, resume, business plans), calendar (activities, habits, regular whereabouts), RSS feeds (passions, interests, and political, intellectual, religious leanings), instant messaging (chat logs with friends, lovers, co-workers), my social graph (strong ties, relationships), my phone calls (the ability to recognize my voice from Google Talk or Google Voice), my photos (facial recognition and identification of my family, friends, colleagues) — nevermind all of the revealing personal information contained in web searches! There are lots of questions regarding each type of data and whether or not you’d want to trust it with someone else, but the aggregation of all of it into a single account is a more noticably bad idea. It’s a recipe for disaster in the event of a privacy leak or breach, oppressive government actions, a supeona, the loss or revocation of your account, etc.
Furthermore, some things I simply don’t want on someone else’s computer ever. I’ve felt comfortable trusting service providers like Google with my email in the past, but I’ve never been comfortable trusting them with my entire address book — that’s not just my data, but other people’s private information too. Similarly, I would never want my personal journal on someone else’s computer — that’s just too private.
However, Mozilla does a fantastic job of handling private data. With Mozilla Weave (i.e. Firefox Sync), not only is it free (libre) software that you can run on your own server, but your data is encrypted on the server. A user has two passwords — one to authenticate with the server, another to encrypt the data locally. Since encryption happens locally, the server only sees the encrypted data and never sees your second password. Mozilla doesn’t even ask for the information to decrypt your Firefox Sync data. You can use their server to sync your data across computers, but it’s only ever decrypted on your computers, not the server. If you use Mozilla’s server instead of your own, Mozilla still won’t have access to your data.
I wish more services providers would do this. I understand it doesn’t work for services that are meant to be accessed directly on the server through the web, but at least for synchronization services it seems like a privacy no-brainer. Funambol, for example, is a great libre software data synchronization server for mobile devices, but I don’t think their gratis service at my.funambol.com encrypts your data. I suppose they have a web interface on their server, but I’d rather run my own Funambol server in the absence of Weave-style encryption, whereas I don’t mind using Mozilla’s Firefox Sync service at all.
Encryption of data in transit is another concern. Does a network service or web application offer encrypted methods of communication? Or is your private data being transmitted out in the open? Gmail now offers HTTPS by default. Facebook and Twitter offer an “Always use HTTPS” setting. The EFF has developed a Firefox add-on that uses HTTPS wherever possible. I’ve started using basic StartSSL Class 1 certificates, which are available at no cost to individuals, in order to encrypt traffic on my home servers.
A good network service should take privacy seriously, and offer encryption wherever possible. I’m not sure that this should be a requirement for a free network service, but it’s an important consideration before using a service hosted by somebody else. However, a service that may fail to adequately protect your privacy as a hosted service could still provide an acceptable self-hosted solution.
Email is a common example of a distributed set of protocols. If Bob uses Hotmail and Sally uses Gmail, they can still communicate with each other. Telephony provides another example; Bell customers can phone Rogers customers, and vice versa. This is the ideal — choosing a service provider independently from the people with whom you want to communicate. Distributed systems strengthen the Internet, creating fewer points of failure or censorship, more opportunities for expression and innovation, more freedom and autonomy for users. This isn’t always relevant for network tools or synchronization services aimed at individuals or small groups compared to social network services and communications tools.
Most online social networking services are walled gardens. Facebook users can only talk to other Facebook users, MySpace users can only talk to other MySpace users, etc. In this environment, social pressure has negative effects on freedom and autonomy. You might not feel comfortable using Facebook, but if that’s where your social circles are active, you’re faced with the choice of being left out or using a service provider with which you’re uncomfortable.
Google Talk makes it clear that it doesn’t have to be this way. Rather than developing their own proprietary walled garden instant messaging service, Google used the open standard XMPP (aka Jabber) for its chat service. With XMPP, you can chat with people on other servers. I have a Jabber account on my own server (and there are dozens of public Jabber servers), and I can still talk with (or call) people on Gmail Chat. I’ve left Google Talk, but I’m not cut off from Google Talk users. Compare that to Skype, which has so far relied on a proprietary VoIP protocol that only lets Skype users call other Skype users (short of bridging to traditional telephony).
In the social networking space, there are efforts like GNU Social/StatusNet and Diaspora to develop distributed solutions. StatusNet has already had some success implementing an open standard for distributed status updates. I’m curious whether Google+ might advance the cause of distributed social networking services (even slightly), given Google’s commitment to distributed systems and open standards elsewhere, and their development of new standards like OpenSocial.
Social network services should be distributed, allowing users to communicate across service providers. Email, traditional telephony, XMPP/Google Talk and GNU Social/Diaspora are all good examples of this. I’m not sure that this should be a strict requirement for a free network service, but the freedom to run the software on your own server is pretty useless for some social applications if you can’t communicate with people on other servers.
Identi.ca, the flagship StatusNet site, is a perfect example of a free network service. It’s free software (AGPL), implements open standards and documented APIs for accessing your data, they’ve pioneered an open standard for distributed networking, and public updates are licensed freely. I’m happy to use Identi.ca.
Mozilla’s Firefox Sync is a good example of a free network synchronization service. Data is encrypted, it’s free software that can be run on another server, and bookmarks are stored locally in a format that other applications can read. I’m comfortable using Mozilla’s service for Firefox Sync.
AGPL network sync services like Funambol and Snowy are also libre services (free software, open standards or documented formats), but in the absence of Mozilla-style encryption, I’d prefer to run them on my own server. The FreedomBox Foundation has been working on an easy way to run libre services from a home server, and make them available to others. I currently use a combination of always-on GNU/Linux home computers available remotely and some dedicated servers that I manage. Even without your own server, you can use free (or more freedom-friendly) hosted services like riseup.net for email, jabber.org or others for instant messaging, my.funambol.com for mobile sync, Mozilla Firefox Sync for bookmarks and browser data, Identi.ca over Twitter, Voip.ms (SIP) over Skype, Libre.fm over Last.fm, etc. If you’re looking to try out some of the self-hosted services, I do have Snowy, Funambol, and Tiny Tiny RSS running on my home server — contact me if you’d like an account to try them out.
The process of disentangling from proprietary network services can take some time, but it’s well worth it for the sake of freedom and autonomy, even when it may be challenging in the short-run. If you can’t leave a proprietary service right away, recognizing where it fails to meet these criteria can help you take some important steps in the meantime.

Free (libre) and open source software is one of the best examples of an alternative to restrictive copyright, but even within these communities there can be heated debates about licensing. The WordPress community just witnessed such a debate between the founder of WordPress, Matt Mullenweg, and the developer of a popular premium WordPress theme, Chris Pearson, over whether or not themes are subject to the GPL (WordPress’ license). The GPL applies to derivative works of a program—requiring that they, too, must be licensed freely—but Pearson maintained quite publicly that he wasn’t subject to it and could use a proprietary license for his theme. This caused tension between him and Mullenweg, until last week, when Pearson gave in and switched to a split GPL license.
This kind of disagreement also highlights the fact that free software licenses (like the GPL) and the free culture licenses they’ve inspired (like some of those offered by Creative Commons) are ultimately hacks on a restrictive copyright system; they’re merely tactics to reverse the negative effects of overly restrictive copyright, but not at all the ideal scenario. For example, we’ve seen concerns over how Creative Commons licenses act as a contractual layer on top of copyright, and non-commercial restrictions can also be a source of tension. Sometimes these disputes help a community to better develop its position on copyright and licensing, but other times, they’re a sign that these licenses are still just a hack on a less than ideal system.
It’ll be interesting to see how Thesis fares in the long-run with a split licensing approach compared to other premium themes that are 100% GPL. Regardless, it’s nice to have a more or less happy ending where the community was able to resolve things without getting the courts involved.

As expected, the Canadian government tabled a new copyright bill today. Despite the consultation last summer, rumour has it that Canadian Heritage Minister James Moore and Industry Minister Tony Clement—the two cabinet ministers responsible for copyright (who seemed to understand the new opportunities technology presents)—couldn’t come to an agreement, and the Prime Minister’s Office sided with Moore’s more hard-line approach. Yet, it appears Clement’s influence was not lost. The proposed legislation, Bill C-32, actually contains many good provisions… but strict digital lock restrictions threaten to undo them all.
The current Canadian concept of fair dealing is more limited that the American doctrine of fair use. The Supreme Court has repeatedly ruled that it should be interpreted broadly, but present law restricts fair dealing to just five categories—research, private study, criticism, news reporting, and review. NDP Member of Parliament Charlie Angus had tabled a private member’s bill to introduce flexible fair dealing back in March, but with Moore’s vision winning out over Clement’s, Bill C-32 rejects flexible fair dealing.
But, it does contain a host of new exceptions for parody and satire, education, time shifting, formating shifting, and backup copies. There’s even a new “Non-Commercial User-generated Content” exception (29.21), which would legalize mashups and remixes under certain circumstances.
While the litany of exceptions fails to introduce real flexibility into the law for new innovations, Michael Geist—leading critic of the last, failed copyright bill—still describes this as “a pretty good compromise.” There are those who strongly oppose the uncertainty that comes with flexibility, so maybe the “there’s an exception for that” approach is the best we can hope for right now.
Though not perfect, it’s still a positive development, and definitely an improvement on the past.
Geist notes two other good compromises. As with the last two copyright bills, C-32 would implement a notice-and-notice system for Internet Service Providers to handle copyright infringement allegations, rather than the guilty-until-proven-innocent American notice-and-takedown system, or the insanely disproportionate three-accusations-and-you’re-kicked-off-the-internet approach. Also, a change to the statutory damages provision would finally distinguish between large scale counterfeiting and non-commercial infringement, limiting the latter between $100-$5000 instead of the current $20,000 maximum. While $5000 per infringement is still pretty ridiculous, cutting the maximum down by 75% for non-commercial infringement would be a positive development.
The huge loophole in this bill is the approach to anti-circumvention provisions, which would make it illegal to break a digital lock even if what you are doing is otherwise non-infringing. It’s important to understand how this massively undermines any good which might come from additional fair dealing exceptions: if there’s a digital lock, the exceptions are meaningless. Bill C-32’s rigid digital lock provisions undo the exceptions.
This has to change. More importantly, it doesn’t have to be this way. Submissions to last summer’s consultation were overwhelmingly opposed to this approach. Other countries have met their international obligations with anti-circumvention provisions that are actually linked to copyright infringement (e.g. New Zealand‘s passed law, India‘s proposed law). With a flexible anti-circumvention provision, the exceptions would apply to digital locks too.
Why should companies be able to rewrite copyright law and trump exceptions simply because they slap a digital lock onto something? If there’s a backup exception, there should be a backup exception. If there’s allowance for parody and satire, no digital lock should be able to take that away. And what’s the use of a format shifting exception if digital locks will force you to repurchase your content to stay legal anyways?
Canada needs to have a flexible anti-circumvention approach that is actually linked to infringement, or none of the compromises in this bill even matter.
There’s an inducement clause (27 (2.3)) which would make it illegal to provide a service online “that a person knows or should have known is designed primarily to enable acts of copyright infringement.” Would the Internet-equivalent of a VCR pass that test? What about BitTorrent? Both technologies can be used to enable acts of copyright infringement, but they also have legitimate uses. How the “primary use” is determined could have significant implications here.
The time shifting provision (29.23) warrants further review, as it contains a variety of conditions under which you can record a program for later viewing. For example, the bill would require that you “keep the recording no longer than is reasonably necessary in order to listen to or view the program at a more convenient time”—seemingly, a requirement to get rid of recordings once you’ve listened to/watched them.
Also, library provisions allowing for distribution are subject to digital locks, and contain a requirement for copies to be destroyed within five days.
There are lots of details like this in this bill that require further study, and most likely revision.
The Conservatives are seeking support on this bill from the Liberals. Liberal Industry critic, MP Marc Garneau, is keen to work with the government to introduce a new law, and is open to the possibility of summer hearings to get it passed. But Clement told the CBC, “I’m not coming down from the mountain with this chiselled in stone… we could seek some consensus and there could be some positive amendments to this bill.”
When I met with my MP, Liberal Joe Volpe, over Bill C-61 in the summer of 2008, his main question to me was whether to scrap the bill or to fix it. Critically, We must let our MPs know—especially the Liberals—which compromises are acceptable, and which undermine the entire copyright bargain. Flexible fair dealing would have been better than a litany of exceptions, but that compromise could work. However, allowing digital locks to undo those exceptions is simply unacceptable.
Politics is the art of the possible, a complex art of balance between ideals and interests. This bill isn’t perfect, but there is a push from both sides of the floor to get it passed. There are a lot of good compromises, but whether or not the bad provisions get fixed could have huge implications on Canadian culture, technology and business in the years to come. Make your voice heard.
Back in March, I was invited by my friend Roman Verzub to the first episode of The Acoustic Assaultcast to talk about music and free culture.
I’ve been a regular user of the fantastic Tomboy note-taking application since I replaced my Palm Pilot with a Nokia N900. With Conboy, a Tomboy client for Maemo, and Snowy, a web application for Tomboy notes, it seems like the perfect platform for uniting personal notes across the desktop, mobile and web (except for one drawback: Tomboy itself is a Mono application…). Initially, I used a hack with Unison to synchronize Tomboy files manually between my N900 and laptop, but I recently moved to proper, albeit still experimental, syncronization through my own Snowy server.
Snowy is a Djano-based, AGPL web service for Tomboy notes, currently under heavy development (and still labelled as experimental). I installed Snowy on my own Ubuntu web server using the official installation guides. I went with mod_wsgi, though I have Django running via mod_python on another server.
Installation was very straightforward. Just a few notes:
Tomboy comes packaged with the web sync plugin in recent versions of Ubuntu.
Conboy focused on supporting the proprietary Ubuntu One web service first, but it now supports synchronization to any Tomboy web service (though the feature is labelled Beta). The only problem I had setting this up was a strange error about a missing api-ref and local time, but it turns out Conboy just didn’t want a trailing slash in the URL (seems like the trailing slash prevented proper authentication at the sync stage).
I’m super happy that the Tomboy / Conboy / Snowy combination is now ready to use, but do pay attention to the beta nature of Conboy sync, and the experimental nature of Snowy — make sure to backup your notes regularly to avoid any data loss.
I’m happy to be a guinea pig myself.
Disclaimer: this is a hack from someone who doesn’t know Tomboy well. It worked for me, but YMMV. And I have backups. And, mostly importantly… .
I wanted a way to sync Tomboy on my Ubuntu desktop with Conboy on my Nokia N900, but Conboy only syncs to Ubuntu One—a proprietary web service. Snowy synchronization support is supposed to be on the way, but Snowy itself is still under heavy development, so this might be a great option in the near future, but not today.
A comment on maemo.org made me think that rsync over ssh was a possibility, and a quick rsync showed this to work (as far as I can tell). The trick is being able to sync changes back and forth; rsync can’t handle updates to both the source and destination—it’s unidirectional.
Hence, Unison—a bidirectional synchronization utility. In case it’s useful to anyone else, this is how I’ve setup Unison to sync notes between Tomboy and Conboy.
First, I want to be clear that this is a temporary hack while I wait for proper synchronization support through Conboy with Snowy.
Prerequisites: I already have OpenSSH running on my server, and I have key-based ssh access configured from both my laptop and N900. Unison syncs remotely over SSH.
What this does: It allows me to synchronize notes and changes to notes from my N900 to my laptop, and potentially to any number of other computers.
What this doesn’t do: Unison has support for handling conflicts, but it’s not the least bit Tomboy-aware. A proper Tomboy sync might give you the option of renaming a note that has been changed in more than one place, but with Unison, you’ll be looking at diffs and merges of cryptically named XML files. So, I don’t recommend relying on Unison to sort out conflicts. I plan to sync often, backup often, and avoid conflicts as much as possible. This is for advanced users.
Tomboy Concerns: I’m using Tomboy, but actually quite uncomfortable with the risk, since it depends on Mono. I’ve considered switching to Gnote, but haven’t yet because I’m concerned about losing data/synchronization compatibility. But, this solution might work for Gnote too, and I may well s/Tomboy/Gnote/g in the near future.
Unison is cross-platform and available for a variety of operating systems
I have Ubuntu on both my laptop and server right now, and I’m syncing through that server (instead of directly to my N900, which would be another option).
In Ubuntu, you can install unison with the command:
sudo apt-get install unison
Or, if you want a GUI:
sudo apt-get install unison-gtk
I created a file called ~/.unison/notes.prf with the following text:
# Unison preferences file
root = /home/balleyne/.local/share/tomboy/
root = ssh://alleyne.to/.local/share/tomboy/
I decided to sync my notes with the Tomboy directory on my server, which is also a workstation.
Now, I can synchronize the notes on my laptop with my server by running the command:
Tomboy doesn’t automatically look for changes to notes on the file system unless you enable the NoteDirectoryWatcher Add-in: Edit > Preferences > Add-Ins > Tools > Note Directory Watcher > Enable. This way, Tomboy will accept any changes you get from the Unison sync.
To compile Unison, you need the OCaml compiler. To compile OCaml, you need the gcc compiler. I began the process of compiling compilers, but then realized that there were some unison .debs available already:
These were compiled for an older version of Maemo, but the command line version seems to be working fine for me in Maemo 5. Note, that if you use the GUI, it’s standard GTK, not a Maemo port, so you might need the stylus to use it.
To install, I ran the following commands:
$ sudo gainroot
# wget http://www.bundyo.org/maemo/unison/unison_2.27.57-2_armel.deb
# dpkg -i unison_2.27.57-2_armel.deb
Similar to step 1B, I created a file at ~/.unison/notes.prf:
# Unison preferences file
root = /home/user/.conboy
root = ssh://alleyne.to/.local/share/tomboy
Now, I can sync my mobile computer with the server by running the command:
And there was much rejoicing.
With Unison configured, I now have a basic, low-level sync between Tomboy and Conboy. I’m getting into the habit of syncing every time I change anything, to avoid conflicts. This should tie me over until a Conboy Snowy sync is available.
This is a quick fix for a problem I had when upgrading to Ubuntu 10.04, after having used the Mozilla PPA.
The Firefox upgrade failed during the distribution upgrade process (from 9.10 to 10.04). I was told to run `dpkg -a –configure`, and the same error occurred again (it’s in bold).
$ sudo dpkg -a --configure

A quick web search brought up a bug report, and I was able to figure out this fix with the help of one of the comments:
On my laptop:
$ sudo dpkg-divert --list | grep firefox
local diversion of /usr/bin/firefox to /usr/bin/firefox.ubuntu
local diversion of /usr/bin/mozilla-firefox to /usr/bin/mozilla-firefox.ubuntu
The clean Ubuntu install returned no results for the above command. (Also, note that in the full output for dpkg-divert –list, those were the only local diversion — another hint that they were from the PPA upgrade rather than Ubuntu itself.)
So, I ran the following commands to remove the diversions:
$ sudo dpkg-divert --remove /usr/bin/mozilla-firefox
$ sudo dpkg-divert --remove /usr/bin/firefox
Then, the most recent Firefox upgrades worked without a hitch on both of my affected machines. Finally fixed… *fingers crossed*
$ sudo rm /usr/bin/firefox
$ cd /usr/bin
$ sudo ln -s ../lib/firefox-<your-current-version>/firefox.sh firefox
$ sudo chmod 0777 firefox
$ sudo apt-get -f install
The symlink for /usr/bin/firefox had been pointing to /usr/bin/firefox-3.5, which no longer existed, so the commands above (1) remove the dead-end link; (2) add the proper link (YMMV depending on which version of Firefox you are upgrading to); (3) resume the upgrade process.
Hope that helps!
My first computing experience was on the family computer, a 386 running Windows 3.1 in my parents’ den. It was truly a family computer—my parents used it for work, and the kids used it for games. A few years later, my parents moved to IBM ThinkPads with Windows 95 (vehicles for my first Internet experiences, dialing into chat rooms to talk about my dog with strangers… I was 9!), but the kids’ computer was still the shared desktop. When the 386 was no longer able to run our games, it was replaced with a new Windows 98 desktop. That shared kids’ computer spent most of its life out in the open, in our family room.
In the next five years, our home computing landscape changed drastically. I got my own desktop when I started high school in 2001. A few years later, I acquired a laptop after a summer trip overseas, and my two siblings (3 and 6 years younger) both got recycled older desktops in their rooms for homework. My desktop became the new kids’ computer, but it was quickly phased out as gaming shifted to consoles and my siblings got upgraded machines. By 2005, our computing took place in separate rooms.
But in 2007, I entered the free software world and developed an interest in bringing old neglected Windows machines back to life with GNU/Linux. I bought a TV tuner card, and turned my old Windows 98 desktop into a MythTV server (among other things). It was an odd project, since I rarely watch TV, but soon enough I had another old computer connected to my MythTV server and setup on the big screen TV in our family room
I soon realized that we didn’t just have a new way of watching TV, but a fully-featured PC hooked up to a giant screen. With a couch and a wireless keyboard, I began using it to browse the web and consume other forms of media (especially useful when we had company!) and even used it for some work (handy for group projects!). It provided a stark contrast to the tethered appliance computers nearby—an XBOX 360 and a Rogers HD PVR (which broke!).
I don’t want any proprietary tethered appliances when I move out. I want a general purpose computer that opens up to the room—not a personal computer that family members take turns using, or a TV that people just watch, but a group computer that brings other people into the computing experience.
With a general purpose computer, I can specialize with software (MythTV for television channels, Firefox for web content, etc.). MythTV is cool, but video is moving from TV to the web—why not focus on that? I don’t know of a real group user interface for general purpose operating systems yet (i.e. like on video game consoles), but a big display goes a long way to involving a room in the meantime. I’m also fascinated to think about how handheld devices fit into the picture, with large tablets for media consumption or smaller tablets as controllers.
A TV is just a big screen. I’d rather have a computer I can own, control and create with hooked up to it, instead of the black box proprietary tethered appliances that commonly broadcast into a room. I don’t want a “home entertainment system;” I want a shared computing experience.
Is there a name for this? I’ve been calling it “family room computing”—or just “room computing”—but suggestions are welcome. I’m just getting some rough thoughts out. What do you think family room computing could look like, with computer users in charge?
ps that original family room computer? It’s still semi-set up in our basement—I installed Debian on it a few years ago to give Fluxbox a try!
