Houdini 1.5
After version 1.03a this is the next version.
I think that Configurable Contempt is an important option. as you can see in IPON rating list, it has shown good Elo improvement.

Strongest chess engine at last!
I think that we won't need other testings, a least for sometime!
As you see in TCEC's Match 6, Rybka 4 proved that it (or she!) is the strongest chess engine in long games (real games) clearly.
Last result after 32 games is:
Nr Engine Pts SB
1 Rybka 4 64-bit 6CPU 17.5 253.7500
2 Ivanhoe B50tA 64-bit 6CPU 14.5 253.7500

Will Netflix Destroy the Internet?
According to Sandvine, a network management company that studies Internet traffic patterns, 10 percent of Canadian Internet users visited Netflix.com in the week after the service launched. And they weren't just visiting—they were signing up and watching a lot of movies. Netflix videos quickly came to dominate broadband lines across Canada, with Netflix subscribers' bandwidth usage doubling that of YouTube users.

Rybka 4 vs Houdini 1.03a - Longer games
GUI: fritz 11
opening book: perfect 2010
Child process priority for Rybka 4: Normal
Hash size: 319 mb
Large pages for Rybka 4: disabled
CPU: AMD X2 3800+(~2 GHz)
Permanent brain: disabled
Use tablebases: enabled
Blitz:1'+30"
1 Deep Rybka 4 w32 1½10½½ 3.5/6
2 Houdini 1.03a w32 2_CPU 0½01½½ 2.5/6
Next time, without tablebases:
1 Deep Rybka 4 w32 ½½1½½½ 3.5/6
2 Houdini 1.03a w32 2_CPU ½½0½½½ 2.5/6
10 games maybe not sufficient, but it seems to me that Rybka 4 is stronger in long time control.
In these games i see that Houdini 1.03a has a bad time management and don't use it's time. For example while Rybka has 38 seconds to think(in the middle of game), Houdini has more than 4 minutes! It is strange that such very strong engine hasn't good time management!
I should run some different tests.
However Rybka 4 is stronger in these games.
good luck
