Planning for change

This sort of thing always worries me. I really wish we had a more formal way of alerting users that functionality was going to go away, rather than just pulling the rug from under their feet when they install a new release.

At Sun, and I’m sure at most other companies that support software products, we have to tell our customers in advance when (certain) features are going away. We can’t just drop them from one release to the next because we’ve gone off the idea.

Personally, I’d like to see GNOME manage this a lot better, perhaps (from the end user’s perspective) via a section in the GNOME release notes that said which features we intended to remove from the next release. The impact of such changes would then have to be thought through well in advance, and there’d be plenty of time to remove the feature, fix any related issues, and properly update the documentation prior to its actual disappearance. And users would have time to prepare for the change, and have the opportunity to raise any sensible objections before the fact, rather than after it.

(This thought isn’t especially new, nor directly aimed at the proposed Windows capplet removal… although I do know that’s a decision that would generate support calls for Sun users and customers, who always scream when anything related to their sloppy focus settings breaks, changes or goes away. Many of them have been using sloppy focus on UNIX desktops since before GNOME or even Linux were first thought of, so it’s not a feature we like to mess with…)

Control center refresh

Some of you have probably heard that some folks at Sun have been working on a proposal for a tidied-up GNOME control center shell. Well, at long last, here are some details!

First of all, I should say that I actually have little personal involvement in this project—it’s being led by Kristin Travis and Jenya Gestrin of Sun’s xDesign team… I’m just abusing my position on Planet GNOME to plug what they’re doing 🙂 And as yet, there’s no production code to speak of, just mockups and Flash prototypes, so there’s still plenty of scope for feedback.

You can download the latest protoypes, peruse numerous mockups, and read about the design process to date (including a usability study on the capplet categorisation) on the Usability Project’s Control Center Whiteboard pages.

Try out OpenSolaris… in your browser

This is a neat idea (if not technically all that novel)… log in to Sun Learning Services portal, and you can play with a virtual instance of OpenSolaris for up to an hour.

It does require Java, there are only 8 slots available at any one time, and right now they’re still provisioning OpenSolaris 2008.11 rather than the newer and shinier 2009.06. But if you want to give OpenSolaris a quick whirl, you might find it more convenient than downloading the LiveCD.

gnome-shell on OpenSolaris

Kudos to Brian for getting gnome-shell up and running on OpenSolaris—since I’ve barely touched a Linux distro in the past year or so, this has really been the main thing that’s been stopping me from taking a proper look at it, and getting involved in what’s clearly going to be an important part of GNOME’s future. I guess I don’t have any excuses now 🙂

Compiz in a Box

In VirtualBox 2.2.0, which was released today, that is. The new OpenGL acceleration for Linux and Solaris guests allows compiz to run very nicely in a virtual machine. (Click the thumbnail for a Theora video of compiz running in an OpenSolaris guest in OS X.)

EDIT: I suppose I ought to add there’s some other cool stuff in 2.2.0 as well, particularly the ability to import/export appliances in OVF format.

Different day, same Places

A couple of years ago, I bemoaned the inconsistency of our presentation of bookmarks and places.

Last week I had cause to revisit the issue (for much the same reason as before—updating the OpenSolaris UI spec), hoping that things would have improved and I wouldn’t have to suggest too many tweaks to the OpenSolaris layout to keep things nice and consistent.

Unfortunately, it doesn’t look like much has changed though, really, which is kind of disappointing. (Especially as seeing this bug marked as resolved had built up my hopes a little…)

Caveat: as in my original post, the latest release of Ubuntu (8.10, GNOME 2.24.1) was the closest I had to a community build when I was doing the comparison. So things may really be a little better or worse than they appear here, or may have been fixed in 2.25/2.26.

So I hacked up a quick diagram showing all the menus and sidebars where bookmarks and places appear, and aligned them on the “Home Folder” entry since that was about the only one that was consistently placed. Here’s what I came up with:

Side-by-side comparison of bookmarks/places in Ubuntu 8.10
Side-by-side comparison of bookmarks/places in Ubuntu 8.10

The plusses:

  • The two Places menus on the panel (one in the menubar applet, one in the main menu applet) are now identical, at least in Ubuntu. This is good to see, although most users won’t see both at the same time anyway.
  • The Go and Places menus in Nautilus (browser mode and spatial mode respectively) are pretty consistent with each other too.

The minuses:

  • Inconsistent appearance/placement of mounted media, Computer, Desktop, Templates, File System, and CD/DVD Creator between sidebars and menus.

Of course, it would be wrong to complain without offering any proposals, and I’ll get to that—just haven’t got time today. The current draft of the OpenSolaris 2009.04 UI spec does include my first quick attempt, but that’s currently based more on “least amount of work to fix” rather than “what might be most useful”… and we all know that’s not really the way to do it, right kids? 🙂

VirtualBox 2.1.0

Sun released VirtualBox 2.1.0 today. In addition to bugfixes, new features include:

  • Support for hardware virtualization (VT-x and AMD-V) on Mac OS X hosts
  • Support for 64-bit guests on 32-bit host operating systems (experimental; see user manual, chapter 1.6, 64-bit guests, page 16)
  • Added support for Intel Nehalem virtualization enhancements (EPT and VPID; see user manual, chapter 1.2, Software vs. hardware virtualization (VT-x and AMD-V), page 10))
  • Experimental 3D acceleration via OpenGL (see user manual, chapter 4.8, Hardware 3D acceleration (OpenGL), page 66)
  • Experimental LsiLogic and BusLogic SCSI controllers (see user manual, chapter 5.1, Hard disk controllers: IDE, SATA (AHCI), SCSI, page 70)
  • Full VMDK/VHD support including snapshots (see user manual, chapter 5.2, Disk image files (VDI, VMDK, VHD), page 72)
  • New NAT engine with significantly better performance, reliability and ICMP echo (ping) support (bugs #1046, #2438, #2223, #1247)
  • New Host Interface Networking implementations for Windows and Linux hosts with easier setup (replaces TUN/TAP on Linux and manual bridging on Windows)

Downloads for Solaris, OpenSolaris, Linux, OS X and Windows are available here.

OpenSolaris 2008.11

Sun are officially launching OpenSolaris 2008.11 today… although as the name suggests, it was pretty much ready to go at the end of last month, and those in the know have been able to download it from both the community website and the distro website since then 🙂 You can join us at 1700 UTC today for a web chat with some of the people involved.

Glynn has written up a good summary of new features, which include GNOME 2.24, ZFS Time Slider, accessible install, and big improvements to plug’n’play printer support, automatic network configuration, and laptop suspend/resume. The number of additional packages available in the repositories has greatly improved since the 2008.05 release, and we now have various repos and a new process that will make contributing packages easier than ever.

Roman Strobl has produced a 12 minute screencast to show off some of the new bits, and Erwann Chénedé has a shorter one that focuses exclusively on Time Slider, which seems to have been generating a lot of interest.

Of course, 2008.11 still has all the usual Solaris goodness like ZFS, Zones and Dtrace built-in, with the Solaris Trusted Extensions now just a click away too, giving you access to one of the most secure desktops on the planet*.

So why not give the LiveCD a spin? You can grab it via BitTorrent, or download the ISO directly from Sun (or alternatively, from the genunix mirror, or via FTP from LTH in Sweden).

* Probably 🙂 (OpenSolaris Trusted Extensions hasn’t received Common Criteria Certfication yet, but the Solaris 10 version was most recently certified at EAL 4+. More information here.)

Step back in time

Slightly crummy name, but great to see the first phase of the ZFS Time Slider project that Erwann, Niall and Tim have been working on coming together in time for our OpenSolaris 2008.11 release next month.

It works a bit like another company’s product of a similar name, except right now ours only takes regular snapshots to the same disk, rather than backing up to removable media (but we’ll probably end up doing that too). It’s not quite the auto-save function that Federico was talking about last week and at GUADEC, but it’s certainly nice to see some of the power of ZFS in use on the desktop at last.
