What Ubuntu Edge is *Really* about

Canonical's Ubuntu Edge campaign on Indiegogo is breaking records left and right, and if it reaches its goal by August 21st, will break the all-time crowdfunding record by a huge margin. In just 12 hours, the campaign raised more than any other on Indiegogo and enough to place within the top 10 on Kickstarter. The phone Mark Shuttleworth has proposed contains some serious hardware and a gorgeous design. Clearly thousands of people want a piece of this vision, but like every project it has its detractors.

Ubuntu Edge is an ambitious project by a large company, two strikes against it in some people's books.
Why doesn't Canonical just fund it themselves and sell it once it's ready? Don't Canonical have more than enough? These people suggest Canonical should just take the risk themselves and release it when its ready.
For those who fear taking a risk on a project that might not succeed or think crowdfunding should be about the little guy, these ideas make sense. And yet, they completely miss the point of Ubuntu Edge!
This crowdfunding campaign isn't really about whether Canonical can afford to produce a limited-run phone. More than the phone itself, Ubuntu Edge is about showing the world that Ubuntu Phone has legs, that there is real demand for this. Even if Mark Shuttleworth can afford to fund Ubuntu Edge, he shouldn't. This campaign may be the greatest statement the community can possibly make to support Ubuntu Touch.
The Ubuntu community is being asked to show that Ubuntu isn't just a great open source project with a track record for excellent software engineering, but a community willing to support hardware development.  The community is proving to OEMs that there is a viable market for hardware with Ubuntu Touch and proving to carriers that people want to buy this hardware.
If tens of thousands of people will pay unsubsidized prices for a high-end smartphone that won't ship for almost a year, breaking all crowdfunding records in the process, that sends a powerful message to OEMs, to carriers, to the media, and to app developers. There is a long road ahead for Ubuntu Edge, but already, the community is sending a clear message. In less than a day, the Ubuntu community has proved that there are thousands of people willing to take a chance on Ubuntu Phone.

I'm also quite confident in Canonical's ability to deliver on their ambitious plan. Canonical has already proven themselves quite capable at bringing Ubuntu up on existing hardware, so their ability to make Ubuntu work isn't really even a question. This will be their first original piece of hardware, but Canonical's OEM partners will probably handle much of the electronics design and manufacturing. Canonical's keen eye for design and concern for usability details is apparent in the hardware decisions revealed so far, and they will no doubt be very involved with the development of the hardware. However, they will likely be working with partners who will know how to engineer the hardware and manufacture the device in volume, which is no doubt the plan.

Right now, the greatest uncertainty for Ubuntu Edge is whether or not the Ubuntu community can step up, break the crowdfunding record, and reach the goal Canonical set for the campaign. The first day was a tremendous success,  reaching more than 10% of the total, but campaigns generally slow down in the middle, and it will be a long road ahead. Canonical and the Ubuntu community have grabbed the attention of mainstream media with a lot of positive momentum already. No doubt OEMs are watching carefully now. Success will almost certainly guarantee future Ubuntu Touch devices, while failure here would hurt Ubuntu's chances with OEMs.
Pre-orders are more than just a chance to get a cutting-edge phone with Ubuntu Touch, Android, and desktop-morphing capabilities. With every pre-order backers vote with their wallets for Ubuntu's success. The people who back this campaign are saying “I believe in Ubuntu Touch, and I'm willing to take the risk of not knowing exactly what it will be or when it will arrive because this is worth it.” Only a small fraction of the potential market for Ubuntu phones will be willing to buy an unsubsidized device sight unseen, and so the effect of every pre-order is magnified because it signals many more potential customers down the road. There may never be another time when voting with your wallet will make more difference for Ubuntu than right now.
This more than anything is why Mark Shuttleworth is asking for the community's help. It's entirely possible he could fund a production run of 50,000 phones and sell them all, but that wouldn't send a very strong a message to OEMs and carriers, much less the mainstream media or the general public. Mark Shuttleworth and the rest of Canonical aren't sending a plea for help but a call to arms, rallying for everyone to join together in support of a greater cause.

And that is the point.

Novacut 13.05

This is a very exciting release because all the Dmedia automation behaviors have now been turned on. Although note that we still don't consider Dmedia production ready, so please only test Dmedia with files you have safely backed up elsewhere.

This screencast walks you through installing Novacut on Ubuntu 13.04, and gives you a tour of all the new features:

This is also an exciting release because the Version One Hashing Protocol has been finalized and is now used by default. The only downside is that because V1 uses our Dbase32 encoding, it's not possible to support Version Zero alongside Version One.

This screencast explains how to upgrade your V0 Novacut library to V1:

In a nutshell, if you've used Novacut prior to this month's release, after you install Novacut 13.05 you'll need to open a terminal and run this command to upgrade your library:

novacut-v0-v1-upgrade

As it seems very few have existing Dmedia libraries they care about, we didn't put much effort into this user experience (obviously), but we did put a lot of effort into making sure the upgrade works correctly. However, if anyone out there has problems upgrading or needs help, please email team@novacut.com, and we'll make sure you get your data migrated.

Special Thanks

Thanks to Marco Buono for making this great Novacut intro sequence:

Thanks to saras fox, David Jordan, and James Raymond for helping me test the V0 to V1 upgrade this month.

And thanks to the many people who have patiently reviewed the many protocol iterations leading up to Version One, especially Hagen F├╝rstenau, Robert von Burg, and David Jordan.

Install Novacut 13.05

Packages are available for Ubuntu 13.04 in ppa:novacut/stable.

If you want to help develop Novacut, it's best to install from ppa:novacut/daily.

Note if you've added both the daily and the stable PPAs, the versions in the daily PPA will supersede the stable versions. So same effect as if you only added the daily PPA. For more details on the PPAs, read about our Monthly Release Process.

Novacut 13.02, with caution

This month's release is a bit different. We're in the process of turning on the remaining Dmedia automation behaviors, and switching from the interim Version Zero hashing protocol and schema to Version One.

Please note that we don't yet consider Dmedia "production ready", so please don't yet trust Dmedia as the only place where you store your files. But turning on these remaining automation behaviors means I feel we're almost there.

We want to be very cautious during this transition, and so we recommend that most users skip the Novacut 13.02 and 13.03 releases. To make this more than just a suggestion, 13.02 has only been released for Ubuntu Raring (the Ubuntu development version, which will be released as Ubuntu 13.04 on April 25th).

Most of our PPA users are on Ubuntu 12.04 LTS (Precise) and Ubuntu 12.10 (Quantal), while we have only a handful on Raring. This is a good thing while we validate these changes. We likewise don't recommend our users upgrade to Ubuntu Raring yet... wait till after the stable release on April 25th.

In the mean time, Precise and Quantal users can continue to use the Novacut 13.01 release. You'll be able to migrate your Dmedia library and Novacut edits from V0 to V1 whenever you upgrade to Ubuntu 13.04.

For details on how we'll do the V0 to V1 migration, please see this post.

What's New

After more feedback and testing, I've decided that we are indeed switching to the Dbase32 encoding I proposed last month. The V1 protocol now uses Dbase32 instead of standard RFC-3548 Base32 encoding, although V0 is still the active protocol.

Most of the work this month was in preparing FileStore and Dmedia for the migration. Dropping Precise and Quantal support also meant we could drop support for Python 3.2, and start taking advantage of some of the richer POSIX features available in Python 3.3. There was also a critical fix so that Dmedia downgrades a drive when metadata about the drive is missing.

For details, see the release notes for FileStore 13.02 and Dmedia 13.02.

Special Thanks

Thanks to Simon Wells, saras fox, and James Raymond for diligently reviewing my many merge proposals.

Thanks to Robert von Burg for continuing to provide feedback on the Dbase32 encoding and the V1 Protocol Specification.

And thanks to David Jordan for his work on porting Graffik to Ubuntu, which is Dynamic Perception's open source control app for nanoMoCo, an open hardware stepper motor controller:

Plus David had a chance to play with the Ubuntu Touch SDK:

Dropping support for Ubuntu Precise and Quantal

Novacut and Dmedia users be warned: in either the 13.02 (February) or 13.03 (March) release, we're going to drop support for Ubuntu Precise (12.04 LTS) and Quantal (12.10).

I know this will be a bit frustrating for folks, for which I apologize. But on the upside: (1) you'll still be able to keep running 13.01 on Precise and Quantal, (2) the next few releases will likely be very boring from a user's perspective anyway, and (3) you'll be able to upgrade directly from 13.01 without loosing your current Dmedia library or Novacut edits.

We're dropping support for Precise and Quantal because, at long last, Dmedia is going to be officially "production ready". Over the next few months, we'll be turning on the remaining automation behaviors, including those scary but deeply important "copy reducing" behaviors.

The biggest reason we're only supporting Raring is we need a smaller target when validating Dmedia. By our current PPA stats, we have very few Raring users, and that's a good thing while we turn on the remaining Dmedia features, just in case we make a goof.

By only supporting a single Ubuntu release initially, we can do deeper validation of Dmedia. Validating Dmedia is going to take multiple physical computers running an extended simulation (at least one week per run). Right now, I don't have the time to personally do this properly for more than one Ubuntu release. I'd rather have higher confidence in supporting a single Ubuntu version than less confidence in it working on 3 versions.

By focusing on Raring, we can have a higher-quality Dmedia release ready when Ubuntu 13.04 starts shipping on hardware, just in case Dmedia starts shipping on hardware around that time (wink, wink).

And although it would be nice to keep supporting Novacut and Dmedia on Ubuntu 12.04 LTS, I think it's far more important to be forward looking and focus on making Novacut and Dmedia amazing on Ubuntu 14.04 LTS.

If you have questions or concerns about any of this, please ask!

13.01, first release of the new year

What's New

Thanks to Simon Wells, the Dmedia browser got a nice makeover and now displays useful metadata:

Other than that, this was a slow month as far as changes that users will notice. However, huge progress was made in finalizing the version one Dmedia Hashing Protocol, including drafting a formal protocol specification. (See the FileStore 13.01 release notes for more details.)

Before finalizing the protocol, we'd like to have at least one independent implementation. Robert von Burg has started work on a Java implementation, and has already provided very valuable feedback on things that are unclear in the specification. Thanks, Robert!

Now all that sounds very geeky, but there is a good reason why we've put so much work into this part. I felt it was deeply important that Novacut work without the cloud, that it be easy to move assets between different cloud providers, and that ferrying hard drives across the sneaker-net be a first-class way to share the assets needed for collaboration.

Cloud services can be unprecedented traps for customer lock-in, and I don't want artists to check-out of one roach motel only to become permanent residents at another. Unless you can get your data out of the cloud, and you have access to the software needed to use your data without the could, you're boned.

Although it's not being used yet, there is a new software component this month: D-Base32. It's an experimental base-32 encoding designed for document-oriented databases. Unlike standard Base32 encoding, it preserves the sort order (so sorting by the binary IDs gives you the same order as sorting by the D-Base32 encoded IDs). We haven't decided yet whether we're going to switch, and we'd love feedback on this. Please see the D-Base32 Design Rationale if you're interested.

Special thanks to Greg McQueen for taking the time to interview me for Digital Gleu:

Install Novacut 13.01

Please follow these instructions to install Novacut on Ubuntu 12.04 LTS (Precise), Ubuntu 12.10 (Quantal), or Ubuntu Raring (the development version). Note that if you've already installed a previous version of Novacut, you'll automatically get Novacut 13.01 the next time the Ubuntu Update Manager runs.

If you're trying Novacut for the first time, you probably want to start by watching this so you understand a bit about Dmedia, and then watch this to get a good tour of Novacut.

Novacut 12.12

What's New

This month was a big milestone for Dmedia because we turned on the active file monitoring.

(Please note that we do not yet consider Dmedia production ready. Please don't yet trust Dmedia as the only place you store your files.)

The active monitoring verifies that the files in your library still exist, have the expected modification time, and have the exact expected file content. This monitoring allows Dmedia to detect hardware failure and respond accordingly. Think of it like really smart RAID that works seamlessly between multiple computers and even the cloud.

The first time Dmedia 12.12 runs, you might notice a lot of CPU usage and disk activity as Dmedia verifies all the files is your library. We don't yet have a smart way of scheduling this background verification, so if it is too annoying you can open a terminal and kill Dmedia like this:

dmedia-cli Kill

For details, please see the Dmedia 12.12 release notes.

Special Thanks

Special thanks to all the new people who continue to file crash and bug reports, including HeCSa, Donalbain, Thibaut Brandscheid.

Special thanks to Simon Wells for diving into development this month. Simon has already made merge proposals for Novacut, Dmedia, and UserWebKit.

And special thanks to Kevin Cloinger for trying a tutorial hang-out-on-air with me. I walked Kevin through adding a new CouchDB view in Dmedia. The only problem is often the text is difficult to read, so be sure to watch it fullsceen at 480p.

Novacut 12.11

What's New

This month was mostly a Dmedia bug-fix release, as we were made aware of a number of critical bugs thanks to our new automatic crash reporting with Apport.

I want to personally thank the many people who took the time to submit crash reports, including David English, Wolf2, Robert von Burg, John Prat, Sean Fell, Matteo Ronchetti, Renias, Angel Guzman Maeso, St├ęphane Guillou, and kliurka (appologies if I missed anyone). I know it's a bit of a pain to submit crash reports, but they are extremely helpful to us, so thank you!

And thanks to Laura Czajkowski for offering me the opportunity to do a guest blog post on how Novacut uses Launchpad. I tried to capture the key best-practices I've learned the past two years to help new projects start off on the right foot.

Asside from all the bug fixing, probably the most noticable change is the Dmedia importer is now even faster (see filestore 12.11 for details). This is also the first monthly Novacut release available for Ubuntu Raring (the new developement version).
