You can find that your own Blog is suffering some Feeds problems after updating to a newer WordPress version.
I’ve been able to resolve them, as far as I know, using this simple procedure.

How to fix it

• don’t insert withe/empty lines at the start end of confing and functions files; functions is a Theme specific file; check if you have one in your own Theme folder.
• go to all plugins that have an option-page and update them saving again their own settings.
• go to Settings and save again every section.
• refresh Permalinks.

Hope it helps!

I’ve tested RenderFlam3 1.3.6 using the last Flam3 2.7.12 release.
The Script finds the new version correctly when it used in the “plain directory” installation.

I’ve got to address more about the “sub directory” mode but I think I’ll completely remove it during the 1.4 development cycle.
There’ll be some utilities script to configure the whole thing removing the main problem about Flam3 installation and keeping the general usage a lot simpler.

Useless, freestyle, pure experimentation designs or, in other words, just a waste of time.

Last Flam3 updates!
Download here: Flam3 2.7.12

Release as 2.7.12 – 05/16/08
*Added man pages.
*Removed upper limit on particle coordinates.
*fixed FSF address in comments.
*update to automake 1.10.1.
*added eps to denom of perspective fraction to avoid infinities (thanks fred).
*Put contents of ‘id’ env var in png/jpg comment block.

Release as 2.7.11. – 04/05/08
*Added 16 bit per channel support to PNG via bpc envar.
*isaac.h is now installed with the flam3 headers. Strip indexing now done with size_t’s to fix bug in large images (thanks Paul).
*Progress callback now returns ETA, and per-thread verbose flag functionality fixed.
*Enumerated spatial filter types now used in flam3.h, taking the place of function pointers (simplifies the API).
*Fix bug by moving precalculation of variation variables to flam3_iterate (thanks david).

Release as 2.7.10 – 03/15/08
* fixed interpolation bug when magnitude of rotation/scaling component of affine transform is 0.
* replaced secant variation with more flame-friendly secant2 (eliminates gap in y direction, scales y-coordinate by weight).
* warning message now printed when unrecognized variation is present in an xform.
* fixed bad inequality when checking for -pi/pi discontinuity during complex interpolation.

Release as 2.7.9 – 02/08/08
* non-zero weights for final xforms no longer allowed, and now have no effect.
* recompiled windows exes with mingw gcc 4.1 to take advantage of scalability improvements in flam3 2.7.8 (was compiling with mingw gcc 3.4 until now).
* for fedora package compliance, flam3.pc.in patched by ian weller and moved use of config.h to c files only.

Release as 2.7.8 – 01/26/08
* better scalability across multiple CPUs by using compare and swap (from Tim Hockin).
* fix bug in large images (>2GB).
* add flam3_srandom and flam3_malloc/free to better support wrapping with python on windows, which links with a different C runtime.
* add –enable-shared option to configure script (from Bobby R Ward).

Release as 2.7.7 – 12/16/07
* fixed bug (rare random crash) identified by david burnett.
i*nitialize new xforms with better defaults for parametric variations (based on interpolated-against xforms).
add id envar, like nick/url.
* add clone_action envar. return to xform interpolation based on complex logs, but make consistent decisions about *counter/clockwise rotation across the sheep edges.
* interpolation_space attribute to flame element can be set to “linear” to go back to the simpler method, or “log” to use this new (default) method.

Release 2.7.6 – 10/20/07
* fixed action string overflow when many xforms are present.
*added ‘print_edit_depth’ env var to control how many levels of tags are saved when using flam3-genome.
*Fixed wrong placement of random improve_colors code in flam3-genome.
*go to five digit filenames.
*fixed bug in supershape variation.
*API cleanup, thanks to david bitseff.

Release 2.7.5 – 08/14/07
* various code updates to assist with compiling under msvc++.
*now can specify –disable-pthread or –enable-pthread to configure to better control compilation. fixed bug preventing *renders of flames with more than 128 xforms.

A flock of spirals warped on a grid modifier due to classical usage of FinalXForm.

L-studio is Windows software for creating simulation models and performing virtual experiments using L-systems.

It consists of:
* two L-system–based simulators, cpfg and lpfg;
* a set of sample models, primarily of plants, each stored as an L-studio object;
* a graphical browser for organizing and accessing objects on local and remote machines;
* a series of editors and other modeling tools for creating and modifying objects; and
* a library of environmental programs which simulate environmental processes that affect plant development.

Quite classic design: a spiral generated by a quad-fold branch plus a bit of recursive details.
Smoothed and rounded version.

“Calling it a teenage scene
And I have a dream,
Don’t know if I’ll be a star
I’m going to play guitar
I’ve seen this rocking cat
I want to be just like that
… …
We’ll be on our own

Take you to the pictures and a dance
In my drainpipe pants
Check the mirror and the old DA
And “You can play in a day””

I’m happy in seeing my own “nimbus 7″ photo featured in the iSGTW (International Science Grid This Week) article about The new Nimbus: first steps in the clouds.
Glad they liked this simple photo!
