From there, it's up to you whether you want to head down the High Availability routes via HADR or pureScale, or the shared-nothing infrastructure of DPF. Or stay with Express if it meets your needs.

    Biggest problem with this fast deblurring appears to be ringing artifacts - the Shan paper has a better algorithm for ringing suppression. I suspect a hybrid approach could get the best of both worlds.

    I also note that the crowd scene in the Adobe MAX demonstration is actually in the supplemental pdf for the link you quoted, although that may just show that all the researchers in this area have a standard set of "problem" images to demonstrate their algorithms against. I'm guessing that that Photoshop implementation is GPU based and I also suspect that those configurations that were loaded in the demo were known-good starting parameters for each of the pictures posted. Reading through the various papers last night, it was fairly clear that the final image quality is quite sensitive to some of the noise parameters and that may prove to be one of the hardest parts to automate for productization.

    This uses a single image as input, and tries to determine a local prior (L) and a motion kernel (f). It switches between optimization of each in turn, and produces results similar to the demo seen in the video. Given that Aseem works for Adobe, I suspect this work is now close to release.

  9. Power users and GNOME on Has GNOME Rejected Canonical Help? Shuttleworth Responds · · Score: 1

    As far as user interfaces go, it is Havoc Pennington's way or the highway. Havoc has this crazy "usability comes from crippling" approach that dumbs down GNOME for entry-level users but makes it wholly unusable for power users.

    I'd most definitely stick myself into the power user category. I've been a GNOME user since 1.4, anything I do more than once has been scripted or bound to custom keys and I have Kupfer for the fast access to anything I can think of, including custom plugins for work-specific tasks. GNOME stays the hell out of my way and that's the way I like it. When I need to reach for something unusual, I can normally hook it via DBus or gconf.

  10. Re:Is that really well tested in the real world? on GNOME To Lose Minimize, Maximize Buttons · · Score: 1

    That's why I cannot stand Gnome. Sometimes it's very nice, like the customized versions for NetBooks, but the default version for PCs which has NO option to tweak it (unless you count recompiles which are worse than Windows registry edits) make it so that I don't and won't use it.

    Pretty much every Gnome tweakable can be changed with gconftool-2 or similar. If you want to hack the code to pieces and compile in something new, feel free, but it's mostly wasted effort because almost everything important can be altered. That the main GUIs are NOT cluttered by dozens of options actually makes a fair bit of sense. Alterations made with gconftool-2 are typically instantaneous, so if you want to change the spacing between buttons or enable compositing, it'll be done as soon as you make the change.

    Now with Gnome-3 there is a new level of tweakability for the power users - the entire UI is written in Javascript and theming is controlled by CSS. So anything you like/don't like/need to change can be rebuilt trivially and tested. So yes - the main UI is getting stripped down but the underlying infrastructure is not.

    There's your problem. No new features should be introduced this close to release. Traditionally, no new feature should be added to a beta, period! They're asking for it.

    I agree, up to a point. It used to be (when I was young and we had to walk uphill to and from school) that alphas were previews of some new features and betas were feature complete but still buggy.

    These days, the beta label is more like an alpha and the term "release candidate" means feature complete. It should also be noted that Firefox landing features is quite different from developing new features in the trunk. These features are only enabled now because they have gone through an extensive bug squashing procedure on their development branch.

    You clearly have never worked on a large software product.

    During development of a product, you will see new bug rates go much higher than fixed bug rates. This imbalance will continue until you stop adding new features and focus purely on stabilization and product delivery. Firefox 4.0 beta 9 is still landing features (some of which have been baking for a long time in separate branches) so their bug rates look pretty sane to me. All products ship with known bugs - you just try to trim the list down to things that users are highly unlikely to see.

    For web browsers, crash bugs are the most dangerous. They may represent routes through the code where bad pointers are being consumed and these can potentially lead to remote exploits. All reproducible crash bugs should be fixed as soon as possible.

    Having browsed through the outstanding bug list for Firefox 4.0 and looked at the planned schedule (late February release), it looks reasonable. If some of the new features lead to a burst of new defects, I suspect that date will move out or features will get blacklists (like the WebGL/ Hardware acceleration blacklists for Linux)

    My only concern is that last time I looked Wayland wasn't ready for primetime, and the intent with Wayland wasn't to be a full replacement for X for most users.

    If Mark Shuttleworth was proposing Wayland for prime-time inclusion in Ubuntu 11.04 or even 11.10, I'd be concerned. But if you actually follow this news story to the original source at http://www.markshuttleworth.com/archives/551 you would find this:

    Timeframes are difficult. I’m sure we could deliver *something* in six months, but I think a year is more realistic for the first images that will be widely useful in our community. I’d love to be proven conservative on that :-) but I suspect it’s more likely to err the other way. It might take four or more years to really move the ecosystem. Progress on Wayland itself is sufficient for me to be confident that no other initiative could outrun it, especially if we deliver things like Unity and uTouch with it. And also if we make an early public statement in support of the project. Which this is!

    So the first likely viewing of this would 11.10 and real integration into the entire stack is more likely in the 14.10/15.04 time frame.

    So this is a classic storm in a teacup right now. The reality is "promising project will be supported by major Linux player for future inclusion".

    The moment someone isn't too happy? Read the history! Developers have been ranting about the closed shop that surrounded the copyright assignments required for contributing to the OO.o tree for years. The go-oo fork was set up as a rational way to keep track of contributions from people who weren't happy to give their copyrights over to Sun, and I think it's fair to say that most open-source contributors were more comfortable with Sun than Oracle. Forking a project this big is not something that developers take lightly and it takes extreme situations to make one happen.

    There are plenty of examples of successful forks out there. Because OO.o version 3.x is LGPL v3.0, and I assume that TDF will stay with the same license, TDF will be able to take whatever OO.o adds, at least while the forks stay close together. However, unless OO.o starts taking code without copyright assignments, the reverse is not true. It is entirely probable that LibreOffice will be become the preferred product, at which point Oracle is going to have to make a call on whether it wants to work with TDF properly, or watch OO.o wither.

It would do us all no good if Mozilla did implement H.264 and then got hooked for megabucks when the H.264 licensing agreement suddenly requires dollars per instance of software decoding H.264.
