Brad,

Just a note regarding the error you are getting loading the Evolution Essay below: I receive an error as well, but if I click "x" on the popup I am able to get into and run it (although it seems I cannot use it interactively, e.g. set my own goal at the end). Just wanted to let you know you can probably use it if you do the same. (Very interesting essay , just got through it only quickly). BTW, anyone knows what is the script used there - it look like eToys but now the same as the eToys script I know - anyone can explain if it's the newer or older version?

Regarding your question about how is the Squeakland image and VM different form "regular" - I assume you are asking explicitly about Linux: I am using Squeak on Linux but am not much qualified to answer your questions, but I see you received no replies on the list so let me try my best - hopefully not misrepresenting. Please see my notes inline:

Hi All,

New to this list. I submitted the following email to squeak-dev. Anyone here answer these? ======================= a few questions on the squeakland browser plugin for unix, if someone in-the-know can answer: Is the squeakland image special? (different from the regular ol' squeak images?)

Probably somewhat different from the "development" "Squeak3.8-6665.image" but close. I think many projects can be run using the 3.8-6665 image as your plugin image.

To get back to "Squeakland image", on rpm-understanding Linuxes, the image can be downloaded as the file "squeakland-3.8-1.noarch.rpm".This the rpm installs (among some images etc) two important files

/usr/share/squeak/SqueakPlugin.image /usr/bin/squeakland (link to /usr/share/squeak/npsqueakrun - more on this later)

Is the vm different too? Or is the only difference the npspeak.so file and the symbolic link it creates (e.g. create symbolic link `/usr/lib/firefox-1.5/plugins/npsqueak.so' to `/usr/lib/squeak/3.7-7/npsqueak.so')

The VM on the squeakland site now is "squeak-vm-3.7i7sl-4.i386.rpm". I think it is packaged differently from a "dev version of 3.7" VM. It installs, most importantly, these files:

/usr/lib/squeak/3.7-7/squeak (exe) /usr/bin/squeak (link to the above) /usr/share/squeak/npsqueakregister /usr/share/squeak/npsqueakrun (exe, linked from /usr/bin/squeakland )

Notice that the location of the "npsqueak*" files is same as location of SqueakPlugin.image.

Now, the "Developement Version": Depending on your version of your "developement Squeak VM + image", the locations where it installs are likely different from where the Squeakland version installs, so it should NOT clash and be overwritten by the "Squeakland versions" if you install both. Please do not take only my word for it though, as I am typically using a different setup (more below). For example, my "developement 3.9 VM" is now installed in:

/usr/local/lib/squeak/3.9-7/squeak (exe) /usr/local/bin/squeak (link to above) /usr/local/lib/sqeak/SqueakPlugin.image /usr/local/lib/sqeak/npsqueakrun /usr/local/lib/sqeak/npsqueakregister

So it seem if 3.9 VM+image is installed first, then "Squeakland", the only thing potentially overwritten would be, after Squeakland's "npsqueakregister" registers the plugin, your plugin would be the one from Squeakland which is likely what you want.

Having said that, I typically try to use developement (non-squeakland) version of VM with the Squeakland's plugin, I do something like this to get the Squeakland image in my installs: 1) Install the "dev" version of VM+Image 2) Find, somewhere, the Squeakland version of SqueakPlugin.image (for example by semi-installing Sqeuakland's squeakland-3.8-1.noarch.rpm). 3) Copy the Squeakland's version of SqueakPlugin.image over the "developement version", for example /usr/local/lib/sqeak/SqueakPlugin.image 4) run the npsqueakregister

I'm afraid the squeakland vm will overwrite my current vm. Is that needless worrying? Can I run them independently (that is without changing directories and creating links so they don't interfere in the "default" installation process)

As I suggested above I think you should be OK if you install both VMs and image rpms, but please verify that (e.g. by looking at the target directories, or asking someone more qualified than me :) before taking the leap.
