I think this is the link you meant:

Google has some truly horrifying results for ktechlab these days,
especially considering all the bugs I introduced into the code recently. =0

EEK!!!

I took another stab at fixing diode today, no luck. =(

The nodes and connectors code is firming up nicely, I added many inline
comments. The biggest open issue is the code which governs the placement
of junctions... The current code causes many *interesting* side effects. =\

Speaking of currents, I think the connector code is good enough to start
taking a more serious look at resolving the issues with the calculation
of currents. I would suggest a procedure of disabling most of the code
except code which transfers information directly from the engine. So for
currents you would either get a correct value or "unknown". From there,
it shouldn't be that unreasonable to design algorithms which correctly
resolve unknown values from known values and fill in at least 90% of the
values that are currently wrong. =(

Given that people actually use this crap, I think we have a
responsibility to try to stabilize what we have right now and focus on
regressions and deliver the best ktechlab ever...

On the other hand, it might be possible to solicit funding for further
development on the project.

Here's a reply I got to a blog post I commented on a few months ago:

Hello Alonzo,
you say that you are the current main developer of Ktechlab so i hope
that you can address some serious issues that IMO are slowing down the
adoption of this excellent piece of software that we call ktechlab.
Before adding new functionalities i think there are stability problems
to be addressed.
I use the precompiled RPM of Mandriva 2009 and ktechlab sometimes
crashes without warning, i also have some friends who use Gentoo and
compile it by themselves who experience the same kind of stability
issues. The same stability problems have been observed by other people
that i know using different distros and ktechlab's versions.

Do you experience them too? Because it is pretty bothering to spend time
connecting components together and then lose all your work for a sudden
and unexpected crash. This is the main reason that keeps me away from
ktechlab. It is a very good simulator and it is a shame that it keeps
crashing when you less expect it.

It would be great to see it used in schools but until it is not stable
enough to be usable i doubt anyone will adopt it.

Adding new functions is cool... but if the software keeps crashing no
one will really use it. Also... i have noticed that disabling the
simulation while building the circuit prevents most crashes... why does
ktechlab start with simulation enabled by default?

Thank you,
Luca

Jeez! I'm shocked that current animation still kinda works cuz I'd been
unaware of that feature, after all this time even! =P
