Right-mouse on a MacBook Pro

I've got a new, shiny MackBook Pro (actually an old one like this but with 15", because I don't like the new ones) and, as probably everyone knows: it only has one button. That sucks very much when it comes to context menus. On my old PowerBook G4 I had some settings in my xorg.conf to enable two- and three-finger taps, but I don't wanted to do that again.

Instead I wanted something to be turned on in GNOME itself. So my attention came to accessibility extensions.

Fortunately I don't need them but there is a nice mouse feature called "Simulated Secondary Click". I wanted to turn on "Trigger secondary click by holding down the primary button", but it said something about "mousetweaks is not installed". Damn...

I searched the OpenSolaris package repositories but couldn't find it. I thought this is a GNOME core package? And what about handicapped people really needing this? So I searched in the spec-files and found this as comment in SUNWgnome-a11y-mousetweaks:

# We have removed mousetweaks from our builds since it is GPLv3.
# For now, leave in the following comment so that our ARC
# recognize that we are not shipping this module starting with
# the 2.24 release.  When we re-integrate this package, remove
# the following line:

I have also filed a bug report to see what the exact problem is.

In the meantime I built it myself from source. I downloaded JDS Common Build Environment (CBE), patched the spec-file a bit:

...and: voila! I have a right mouse. Nice.

(free) OpenJDK on OpenSolaris, Part 64

After getting the 32-bit IcedTea built, I also want a 64-bit OpenSolaris version. But I can't get over this error:

1. ERROR in
(at line 28)
        import com.sun.tools.jdi.LinkedHashMap;
The import com.sun.tools.jdi.LinkedHashMap cannot be resolved
1 problem (1 error)make[7]: *** [../generated/sa-jdi.jar]
Error 255

I am absolutely sure I had the same issue with the 32-bit build, but I can't remember how I fixed it. Damn!

So I decided to build OpenJDK directly with my pre-built IcedTea. Again it took some workarounds, but it worked:

$ java -version
openjdk version "1.6.0-internal"
OpenJDK Runtime Environment (build
OpenJDK Server VM (build 10.0-b19, mixed mode)

And the actually wanted 64-bit version:

$ java -d64 -version
openjdk version "1.6.0-internal"
OpenJDK Runtime Environment (build
OpenJDK 64-Bit Server VM (build 10.0-b19, mixed mode)

Now I will try OpenJDK7.

(free) OpenJDK on OpenSolaris

Today I was able for the first time to build OpenJDK on OpenSolaris completely with free tools. Unfortunately I couldn't use use CACAO as bootstrap VM because Boehm-GC has some problems on OpenSolaris, which I couldn't fix yet.

Since GCJ also uses Boehm-GC, I decided to use JamVM. The port was very straight-forward, except one small getcwd problem for which Robert already had a fix for. I will contribute all JamVM changes back to Robert.

After some IcedTea build system changes (yet to commit), some JVMTI file copying (maybe this is a JamVM bug, see instructions at the end), a small OpenJDK patch and some time, I got:

IcedTea is served: openjdk/control/build/solaris-i586

And, obviously, the build works:

$ uname -a
SunOS workstation 5.11 snv_98 i86pc i386 i86pc Solaris
$ java -version
java version "1.6.0_0"
OpenJDK Runtime Environment (build 1.6.0_0-b12)
OpenJDK Server VM (build 1.6.0_0-b12, mixed mode)

I tried to write down all stuff that needs to be done here, but I'm very sure some steps are missing...

CACAO 0.99.3 runs Jake2

Two days ago I actually released CACAO 0.99.3, but didn't have time to do the announcement yet. Nonetheless the release has one very cool feature: you can play Jake2 for the first time! Simply run the Jake2 Webstart (I used the jogl-1.1 one) and start fragging.

Here is a screenshot playing it on x86_64-linux:

It should run on other architectures too, I'll try powerpc when I'm back home.

Finally: OpenJDK 6 b11 on Alpha Linux

Yesterday I finally was able to finish the OpenJDK build on Alpha Linux. I'm not exactly sure what really fixed the build, but definitely adding the missing compiler flags again (with -D_LITTLE_ENDIAN) helped. When Gary commited his zero work we lost some architecture dependent flags, I'll re-add them ASAP.

And now to the fun:

Finally a new release... and another one.

Pheew! After more than one year our codebase was ready to get a new release... so I did. And then I noticed, because I was a bit out of practice doing a release, it had a few bugs. Yeah, of course :-( So I made another one, called 0.99.1.

With official OpenJDK Java runtime library support we are now heading to a 1.0.0 release. I hope that one will be without bugs...

Changing Emacs' default font

I wanted to change the default font of Emacs without setting properties in the .Xresources. The window font can be changed with:

M-x customize-face RET default RET

I set it to misc-fixed with height 113.

The menubar font can be changed with:

M-x customize-face RET menu RET

I'm still searching for the correct font, but in my .Xresources it was:

Emacs*menubar.font: Lucida
Which OpenSolaris package contains pkg-config?

It took me some time to figure that out, because it's not installed per default from CD and I haven't upgraded the whole system yet (because I'm still running on my swap partition).

It's in SUNWgnome-common-devel. Pheew...

Password storage of nwamd(1)

Because I didn't know my WIFI password from the top of my head, I entered the wrong one when nwamd(1) was asking for it. But it didn't ask again. So I wondered where the passwords are stored.

After some google'ing I found the correct command:

# dladm show-secobj

Then I could delete the stored password with:

# dladm delete-secobj nwam-twisti-xx.xx.xx.xx.xx.xx

It seems dladm(1) is just a frontend for text files. The passwords are actually stored in /etc/dladm/secobj.conf.

Switch to OpenSolaris?

I'm thinking about to switch to OpenSolaris on my Apple mac mini. I installed Indiana on my Linux swap partition to see how it works.

Right now I'm trying to get suspend working (http://blogs.sun.com/randyf/entry/solaris_suspend_and_resume_how), but I'm not sure it will work with this version:

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
