Parallels is driving me nuts. If I try to run Vista, it maxes out the CPU constantly, even in the background. In contrast, I’ve had two VMware Fusion VMs (Vista and XP) running in the background all morning, and I forgot they were there.

Just about to give up on Parallels
Wednesday, July 18th, 2007What’s in the Mac OS X version of Silverlight 1.1 Alpha?
Tuesday, May 1st, 2007I downloaded Silverlight 1.1 Alpha and poked around until I found out where the .NET stuff lives. Here’s what’s in the bundle:
$ cd /Library/Internet\ Plug-Ins/Silverlight.plugin/Contents/MacOS/ $ ls CoreCLR.bundle System.Core.dll IronPython.Modules.dll System.SilverLight.dll IronPython.dll System.Xml.Core.dll Microsoft.JScript.Compiler.dll System.dll Microsoft.JScript.Runtime.dll agclr.dll Microsoft.Scripting.SilverLight.dll agcore Microsoft.Scripting.Vestigial.dll slr.dll Microsoft.Scripting.dll slr.dll.managed_manifest Microsoft.VisualBasic.dll
And check out what those DLLs are made of:
$ file System.dll System.dll: MS Windows PE 32-bit Intel 80386 console DLL
But what’s this thing? Man, that’s big!
$ file agcore agcore: Mach-O universal binary with 2 architectures agcore (for architecture i386): Mach-O bundle i386 agcore (for architecture ppc): Mach-O bundle ppc $ ls -l agcore -rwxr-xr-x 1 502 admin 16083600 Apr 26 03:16 agcore
So how much of those DLLs are managed code? Do they contain Win32 code, and does agcore have some magic in it for bootstrapping Win32 code?
Does the Vista EULA Really Prohibit Virtualization?
Monday, February 12th, 2007I don’t think so, and here’s why. The EULA that this post refers to says (emphasis mine) “You may not use the software installed on the licensed device within a virtual (or otherwise emulated) hardware system.” I’m certainly not a lawyer, but it sounds like the scenario addressed is taking the copy of Vista that you’ve installed on your PC, and running that same copy under virtualization.
The EULA (yes, it’s titled Ultimate, but it includes terms for other editions) defines a licensed device:
Before you use the software under a license, you must assign that license to one device (physical hardware system). That device is the “licensed device.” A hardware partition or blade is considered to be a separate device.
And the prohibition against using Microsoft’s DRM within the virtual machine makes no sense unless you are talking about two identical copies (same activation key) of Vista running on top of each other.
So there’s some ambiguity here, and it would be great to get some clarity from the Vista team. But here’s the thought I keep coming back to: if you go out and buy a copy of Vista that you intend to run only under Parallels, the only thing that seems to remotely qualify as the licensed device is the virtual machine itself. Here’s how I think the legalese translates:
“You may not use the software installed on the licensed device within a virtual (or otherwise emulated) hardware system.”: You can’t take the copy of Vista you installed on your PC and run it under any kind of virtual or emulated system.
“You may use the software installed on the licensed device within a virtual (or otherwise emulated) hardware system on the licensed device.”: You can take the copy of Vista you installed on your PC and run it under virtualization or emulation, but only on the same PC.
Fedora Core 5 on Virtual PC 7 for Macintosh
Thursday, April 13th, 2006I posted an entry a while back about getting this to work under an earlier beta of Fedora Core 5. I think these instructions are much more straightforward. You’ll need to go through the installation. I suggest using text mode if you can (I specified “text expert” when I was installing).
When installation is finished, and you are prompted to reboot, use Alt-F2 to switch to a virtual console (Ctrl-Alt-F2 if you are in X11). Then, mount the install media:
# cd /tmp # mknod hdc b 22 0 # mkdir /mnt/cdrom # mount /tmp/hdc /mnt/cdrom
Copy the i586 kernel over to root’s home directory on the new system:
# cp /mnt/cdrom/Fedora/RPMS/kernel-*i586* /mnt/sysimage/root
Unmount and eject the install media and chroot into the new system:
# umount /mnt/cdrom/ # eject /tmp/hdc # chroot /mnt/sysimage/
Install the kernel and exit the chroot:
chroot# cd root/ chroot# rpm --force -Uvh kernel-*i586.rpm chroot# exit
Use Alt-F1 (or Alt-F7 if you were in X11) to return to the installer, and
reboot as prompted.
Ubuntu Hacks @ LinuxWorld Boston
Wednesday, April 5th, 2006
I’ll be giving a short talk and demonstration on Ubuntu Hacks today (Wednesday, April 5 at 12:30) at the O’Reilly LinuxWorld booth. Drop by and learn about getting Ubuntu running under colinux, going online with a Bluetooth connection and a cell phone, and a few more things.
OpenSPARC
Wednesday, February 15th, 2006OpenSPARC Goals: “To significantly increase participation in processor architecture development and application design by making cutting-edge hardware IP freely available.” Getting the obvious Bart Simpson reference out of the way quickly (how long do you figure before they reword that first bullet point?), I’m wondering how someone like me could hack this? I can’t fab chips in my basement… yet. But Qemu emulates a SPARC. Is there an opportunity for SunSource there? An emulator does not need to be full speed to be useful. (via Smart Mobs).
