542 works in VMWare with pcnet32 driver (Just a post to give a link to the package, really...)

Have the converted official 542 image running under vmware with networking now. For those playing along at home it's the same process as for VirtualBox: download the compiled pcnet32 stuff for the 542 kernel into the image and unpack into the /lib/modules/${kernel}/drivers/net/ directory. Run /sbin/depmod as root, and switch on-boot to true in /etc/sysconfig/network-scripts/ifcfg-eth0 . ...
PyGTA this Tuesday (ctypes-ing the night away...)

Peter Hansen, one of the original founders of PyGTA will be discussing, among other things, Engenuity's use of ctypes. Normal place and time (7pm, Third Tuesday of the Month).
VirtualBox seems to have forgotten (Or I did...)

Unable to get VirtualBox-hosted machines onto the net yesterday. Seems the NAT network inside VB just gave up trying to route information out. Kinda killed my plans for trying to build the kernel inside a snapshot of 542 (instead of spending days getting Fedora installed). I don't recall having to do anything other than reboot ...
Tantalisingly close on VirtualBox for build 542 (Networking works, just doesn't go anywhere)

Spent a few hours discussing developer (content and software) relations issues with Mel this afternoon. While doing that (and before) I've been handling various other odds and ends. One of them was getting the pcnet32.ko driver built for the olpc kernel.
Did manage to get that done (eventually). It loads and I can ping the ...
Wow, locked VoIP routers are annoying (Especially when you ask for unlocked explicitly...)

Picked up a VoIP router for my sister today. Chap at Canada Computers assured me it was an unlocked router, despite the "Earthlink" branding. Got home, installed it, and it's locked. Now I need to trek all the way back down there to return it. Bah.
Here's an idea for Linksys: have a way to ...
Cairo's slow if you're doing lots of overdraw (Porting in a turtle-graphics sample...)
Written by

Ported one of the samples from TurtleArt over to the Cairo-based test. OMG it is slow. TurtleArt is bitmap-based, so once it's drawn something it's just blitting up the bitmap next time and then continuing to render. The Cairo renderer is doing the whole rendering process every frame. Some of these samples are rendering radial ...
This should not be this hard (Qemu or chroot'd loopback mount...)

Looking at what to recommend for developers wanting to get started this evening.
Xen doesn't seem like a readily deployed solution: manually rework your whole boot system, build multiple kernels, edit configuration files, hope it works. Fine for sysadmins building computers every day, but not a programmer's favourite way to deal with their primary development ...
Turtle now animates (No turtle graphic yet, though)
Written by

in
Young Coders.
Have pushed updates that let the turtle's graphics get animated via the GUI. Code doing that is still pretty simple, but it seems to work reasonably well in terms of animating what was done to draw the graphics. Uses the whole command-set (at least, what's been drawn to date) to determine scale/transform, so that the ...
Think I've basically "got" bzr now (We'll see...)

Have pushed a copy of my bzr repository up for the spike-test of Cairo rendering Turtle graphics. You can get it by installing bzr and then doing:
bzr branch http://www.vrplumber.com/bzr/hare-graphics
Not much has changed since last night, I've just been working on figuring out bzr and doing a bit of clean-up to make the code ...
Cairo feels a lot like OpenGL (Turtle graphics interpreter spike-test limping along...)
Written by

I got a simple spike test done for PyCairo usage. Mostly this is just me figuring out how PyCairo works and how it and PyGTK interact. No big deal right now, it takes turtle commands from the turtle object's queue (produced by Python source running in a background thread) and translates them into simple Cairo ...
