Review: Oracle Database 12c

tjwhaynes Re:If you have to ask, you can't afford it (147 comments)

Developers can and do build full turnkey solutions at zero speculation cost. Try that with DB2 or MS Foxbase Pro.

DB2 Express is free, to allow developers to experiment and build up solutions with zero cost. Last time I looked, it was also the most deployed commercial database solution in the Amazon EC2 cloud. 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.

P.S. Standard disclaimer: I work for IBM

OpenGL Becoming a Requirement For the Linux Desktop

tjwhaynes Re:And? (229 comments)

I AM running Ubuntu 12.04 on an AGP Nvidia 6800 GT with an AMD 3400+ cpu - no problems (apart from it not being able to run anything using better shader model effects at anything more than slideshow frame rates - I'm looking at you, Braid). Gnome Shell, standard Nvidia drivers (not the free ones).

Fedora 17 Released

tjwhaynes Re:No Unity? (141 comments)

I still miss 'window title search' and 'show all windows for an app' that I had in compiz.....

Window title search: https://extensions.gnome.org/extension/317/window-display/ shows the matching windows in the Overview as you type.

Show all Windows for an app: Maybe I'm missing something but I use Cycle through the apps with Alt-TAB, Cycle throught the windows for an app with Alt-AboveTAB. Which means to cycle through the windows for the current app, one press of Alt-AboveTAB shows the set. I use the cursor keys in Alt-TAB to navigate as well - not sure that is in Vanilla Gnome 3.4.

Database and IP Records Tie Election Fraud To Canada's Ruling Conservatives

tjwhaynes Fricking Right On (257 comments)

I'm glad to see that there are other people out there who share my despair at the Canadian political scene. When I watch the current Conservative government repeal six pieces of environmental legislation in a budget bill, I know things are seriously out of whack. I'm just waiting for the Copyright reform bill to reappear - the last draft was pretty much written end to end by the MPAA/RIAA pundits, despite the claims that this was a "Made in Canada" production. Oh, and I'm also glad to see someone who hasn't bought into the rebranding of the Alberta Tar Sands as the "Oil Sands". Go stick your hand in the damn stuff - it's pretty dry sandy tar. Just you can fractionate the more volatile elements of out it doesn't change the facts - this is a bitumen heavy cockatil.

How Do I Get Back a Passion For Programming?

tjwhaynes Go find something to work on that MEANS something (516 comments)

If you aren't appreciating the work you are doing now, consider asking your favourite local charity what software they need or what information they would like to gather and try and produce something that actually helps someone you can meet and talk to.

I've just been working on a prototype project for a local hospital who are trying to work their way through the social networking jungle, trying to assess whether their messages and fund raising is actually getting out there. You'll probably find that your local charity is awash with similar concerns but has no money to invest. Most experienced programmers can quickly pull a twitter aggregator, a facebook search app, a database and any amount of free software together and actually answer some of their questions. Or write a mobile app for them to distribute. Or help them improve their web service.

Adobe Demos Photo Unblurring At MAX 2011

tjwhaynes Re:Siggraph 2008 (251 comments)

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.

Adobe Demos Photo Unblurring At MAX 2011

tjwhaynes Siggraph 2008 (251 comments)

This looks very much like the paper "High-quality Motion Deblurring from a Single Image" by Qi Shan and Jiaya Jia (Department of Computer Science and Engineering, The Chinese University of Hong Kong) and Aseem Agarwala (Adobe Systems, Inc).

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.

Has GNOME Rejected Canonical Help? Shuttleworth Responds

tjwhaynes Power users and GNOME (181 comments)

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.

GNOME To Lose Minimize, Maximize Buttons

tjwhaynes Re:Is that really well tested in the real world? (797 comments)

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.

Indeed. 8 cores and still >10 seconds until something happens when I press a button.

You've got Malware!

Seriously, scrolling is instantaneous on my laptop, a T61p vintage 2006 with Core Duo. Loading a page with 100 comments - about 1 second. Loading this 1300 comment monstrosity - about 4 seconds to interactive display, about 15 seconds to complete. Firefox 4.0b9, F14.

Firefox 4, A Huge Pile of Bugs

tjwhaynes Re:Rate of incoming new bugs v.s. outgoing fixed b (481 comments)

Firefox 4.0 beta 9 is still landing features

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.

Firefox 4, A Huge Pile of Bugs

tjwhaynes Re:Rate of incoming new bugs v.s. outgoing fixed b (481 comments)

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)

Firefox 4, A Huge Pile of Bugs

tjwhaynes Re:In the spirit of more "freedom" for their users (481 comments)

That said, there is a really annoying bug in Beta 9 - some of my tabs, after I close them, still exist in the ether somewhere and the Awesomebar wants to "switch to tab" when I go to that URL, and there's no tab to switch to, making me press alt+enter to open a new tab.

Check the new Panorama feature to see if it has eaten your tabs.

Ubuntu Dumps X For Unity On Wayland

tjwhaynes Re:A bit big for their britches? (640 comments)

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".

33 Developers Leave OpenOffice.org

tjwhaynes Re:LibreOffice will join the ranks of Linux... (500 comments)

...in no time, with 300+ variations. This is what I hate about OSS. The moment someone isn`t too happy, they get the fork off and duplicate the work and dilute any chance of completing the damn thing, rather than working things out.

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.

Oracle Asks OpenOffice Community Members To Leave

tjwhaynes Re:Oracle = Predictable? (589 comments)

And you certainly don't have to "reverse engineer" RTF -- you can download the spec from Microsoft. It's proprietary in that it's not an open specification, but it's not the dark mysterious pit of hell that the Word binary format is.

Except, like all Microsoft specs, they aren't complete. Nor does RTF == page description languge. Using RTF with two installations of the same MS Office level where the default fonts and margins have been changed on one will not transfer perfectly.

Creative Commons Video Challenges Hollywood's Best

tjwhaynes Re:That is fucking awesome! (455 comments)

The movies (and games) that the Blender Foundation sponsors serve two purposes.

First, they act as a showcase for the technologies currently available.

Secondly, and far more important for the software, the work flow and features required by modern animation teams drives the development of the Blender on. Sintel is built with the latest generation of Blender - 2.5 - which is still in beta. The requirements of Sintel have been developed in Blender in tandem.

Someone said 'it looks like a game trailer'. While I suspect it was intended as a put-down, it is actually a tremendous compliment. Modern computer games pack huge artistic and development muscle, cost tens of millions of dollars to develop and pull in the technical muscle of huge companies. That Blender can enable a small team of deveopers, animators and digital artists to produce something like shows the capabilities of the team and the software.

Photoshop CS5's Showpiece — Content-Aware Fill

tjwhaynes Been there, done that (for free) (378 comments)

These are graph-cut or similar algorithms. There are several free alternatives which have been out there for years. Two spring straight to mind - the resynthesizer plugin for the GIMP and GREYCStoration image inpainting.

  • http://www.logarithmic.net/pfh/resynthesizer/removal
  • http://cimg.sourceforge.net/greycstoration/demonstration.shtml

CS5 seems to have made this easier to use but the functionality has existed for ages.
