Mobius' Dispatches from the Front

July 21, 2019
Up to Crazy 8 Extreme beta 0h now. This game puts up a good fight.  I don't win at all. The program doesn't cheat but it does make adjustments in play based on the number of cards other players are holding.  I was going to refine that and only test the player in the direction of play but so far the computer players have no problem beating the human.

The Crazy 8 Extreme program has been updated to beta 0g.  All the features I needed to add are in.  For play of 3 to 5 players.  It saves games and restores them.  It is pretty much done.  I may polish things up for the release version and remove generation a log file.  That is for testing.

The Crazy 8 Extreme program has been updated to beta 0c.  Programming the progressive two option was a bit difficult.   But it seems to be working.  It is set to automatically play the players hand if they have to play a 2.  I may have to add back in some player control where the player may choose to draw cards instead of playing a 2.  Thus maybe preventing a full circle of twos to come back on them.. 
The algorithm is really pretty good.  It does beat me quite often.  I wouldn't call it an A.I. But rather a formula of play.  It uses a weight system to prioritize cards.   Some weights have random elements so it isn't all rote.

The Crazy 8 Extreme program has been updated to beta 0b.

July 7, 2019
I decided that I could write a program that  played Crazy Eights with the card rules I wrote up.   This is in beta form right now.  Some other features for saved games need to be added and tests for failure have to be done.

And now for something completely different.    Rules for a Crazy Eight like game.  [PDF]
What is amazing is that the Crazy Eight system has been incorporated in a number of commercial games over the years in a number of different countries.  Uno is an American version but there are games from Germany, Israel, Czech Republic and Hungary.   Looking up various derivations on Wikipedia rules sometimes enforce mostly silence to calling out cards played in silly voices to conspiring between players.

The Panzer War Japanese gun tables slightly revised. Sights went to 24% and some penetration values revised as they now use calculated values from NaaB2.

May 28, 2019
The Panzer War German,  British and French gun data tables have been updated as a format problem only displayed one digit of the stun value.

I added a new page explaining the problems of the 152mm gun data.  Link

Trying to produce my own firing tables for the 152mm shells I find that Wiki has a lot of wrong data.  I don't know how many times I had to make a redo on my Russian tables and PW tables. Finally had to rely on CIA pdfs of Russian data.

May 7, 2019
I came across two original documents on the Russian 152mm gun/howitzer.  The earlier one of 1937 report of the ML-20 updated and released in 1944.  This has a firing table of the BR-540 AP shell without striking velocities but with time-of-flights which are impossible as the time for the first 500m is the same as from 1500-2000 range.  In effect the shell does not lose velocity in its first 2000 meters.  This report has a penetration table based on the Demarre formula of the standard K=2400 type. Solving for velocity using this table gets some incredible numbers as well.
The other document is a 1943 report of the 152mm ML-10 updated and released in 1968.   This has a firing table of the BR-540 AP shell with striking velocity as well as realistic time of flight.  So this appears to have good numbers.  I can use the ballistics of the ML-10 BR-540 for the BR-540 of the ML-20.  The velocity difference is only 40 m/s.  What I may do is run both of these shells through NAAB and see what I get.

NAAB has been updated.

I updated the tank gun tables for the German, Russian, USA, and UK.  This reflects accuracy calculations of guns based on optics.

My run for the March Madness this year chose Gonzanga to win but Virginia to come in second. As they say missed it by that much.

March 20, 2019
March Madness 2019.   I worked up the data for March madness computer program again this year.   A couple of teams are to be determined but they are down the list.

There is an entertaining video on Youtube comparing the Panzer III with the early T-34.   Link  The problem is they got a few things wrong.  Like the Soviets didn't use the 76.2mm Pzgr. 39 rot shell.   That was a German manufactured shell meant for captured Soviet guns. 

Also German sights didn't give them much of an advantage when the ballistics of their gun is taken into account.  The lighter 50mm shell lost velocity faster than the heavier 76,2mm projectile. With the dispersion of both guns and the ballistic curve taken into account both would have about a 40% chance to hit each other from 840 meters. 

BTW - I have some videos on Youtube as well if you follow

Something I've been trying to find is the ballistics of the pre-Pzgr 39 50mm AP shell.  This had an ogive nose.  The newer Pzgr. 39 had an AP cap that had a chiseled shape.  Going by the relative ballistic differences in British 6 pdr AP vs APC and US 37 AP vs APC the ballistic coefficient of the APC would have a very small advantage over the AP.
