Arduino LCD die roller for Eclipse Phase
Tonight I wrote this die roller for Arduino with a LCD shield to show Eclipse Phase dice results (d10) and (d100) while watching a movie, the code is a gist, LCDDiceRoller.ino. To get true random, had to use the TrueRandom library.
Based on some analysis of the data using ruby descriptive_statistics library I wrote a simple data reader to test the TrueRandom data at singlestat.rb. The raw data is on ledlogic.net
$ ruby randomstats.rb
{:number=>5301.0, :sum=>240566.0, :variance=>735.0908311889833, :standard_deviation=>27.112558551139788, :min=>"1", :max=>"99", :mean=>45.38124882097718, :mode=>"56", :median=>44.0, :range=>98.0, :q1=>22.0, :q2=>44.0, :q3=>64.0}
The values seem biased low.
The entropy library might be a better choice for true randomness.

Unity 3d Eclipse Phase Dice Roller
Thinking of making a utilitarian dice roller for Eclipse Phase. Can't decide if I should go all unity-3d or just keep simple 2d for now.
- I see a reference to a previous program in the forums
- Found this Unity dice making tutorial.
- These polyhedra are available in the Unity store for $5.00.
Started a unity-based roller, Unity-DieRoller, using the plugin from the store mentioned above. It took a while for me to realize that the dice kept falling using a mesh, until I saw a tip in the unity forums to make the mesh collision convex.
Eclipse Phase Fonts
In an attempt to track down the Eclipse Phase fonts used, I added a note to these font questions in the forums
Eclipse Phase Fonts
- Nikona X2 - main font used on the cover of the rulebooks, slightly tweaked and cleaned up, family here.
- Binary ITC - I think this is used on some covers, example Sunward
- Heliotype LET - Used in headings
- Lato by LUKASZ DZIEDZIC, used in tables
- Sabon - this might be the body text, I saw a reference to an error message in the EP forums
Similar
- Kimchi
- Zipsonik
- ReceptsNF
- Data 70 - a 70s or OCR font
- Time Machine - more rectangular 70s or OCR font
- hirosh - which is really a modified Sukiyaki by Gene Eidy

Comparison of Tomcat connections to JDBC connections
I tried posting this as a survey question on stack overflow, but apparently it is too broad they said.
Perhaps I can still get some comments/ feedback from people through a blog.
I'm tuning ratios between Tomcat 6/7 server threads and Oracle JDBC threads to avoid "Waiting for Idle Object" errors and wanted to get a sample of production ratios.
I'd like to gather metrics and provide some analysis back to the community. If you can, please provide your production quantities of max tomcat server connections and max jdbc connections (please don't post the whole server.xml or sensitive information). I realize every application is different, but it'd be interesting to see if there are general rules or correlations.
Here is a link to the survey.- This - using 400:200
- These setups for Weblogic seem to use a 1:1 ratio.
- This - requested server.xml for comparison.
- This uses 25:55 (1:2.2) ratio.
- This had the Connection Timeout : Waiting for Idle Object. issue with 600 server connections and 100 jdbc connections.
- This - should have jdbc > threads.
- This - says 1:1.25 should work (safety factor).
- This has an interesting article (related to flexypool) on performing the analysis
- This reading on p.95 says start with 1:1 but then add at least one to prevent deadleak.
- This recommends a funnel approach HIS(1000) -> WAS (50) -> DB (30).
- This suggests a 200-800 range.
- This suggests 200-800 (400 to start). connectionTimeout > 20000 too high (we are 60000).
- This 800-1000 for a quad core machine is no problem.
- This shows a 1.875:1 ratio.

Jrebel might want to rethink their target market... I completely ignored the advert but my 10-yr old son noticed it from across the room. Personally I think you would never be able to get the smell out of the car no matter how many febreeze attempts.

Eclipse Phase: Ship Models
Great renderings of a near warp capable ship the IXS-Enterprise from Mark Rademaker. (Incidentally how cool would it be to have "maker" in your name?) Found the reference here (2013).
