I was talking to Liz about Aida (our new child) the other day. She wanted to see a catalogue of what all the different versions of our children would look like. "Hmm...", I thought. "I think that would be quite a big catalogue." It's currently impossible to produce such a catalogue as we don't know all the genes that contribute to appearances. However, I did figure out how unique Aida is.
There are 46 chromosomes per individual. During reproduction 23 chromosomes come from each parent. Therefore, there are 223 (8,388,608) different possible reproductive cells per parent. Each egg could combine with any of the 223 different sperms, so there are 8,388,6082 or 70,368,744,177,664 (70 trillion) different combinations of people that could result between any human couple.
Aida is not so much one in a million, but 1 in 70 trillion. (This does not take into account random mutation.)
If we were going to look through the catalogue, at one snapshot a second, it would take a million years to see every possible combination.
If Liz and I were any other of the great apes, Aida would be far more unique, 1 in 281,474,976,710,656 (281 trillion) as most of the great apes have 48 chromosomes rather than 46 (one of ours got fused along the way).

Death in Haiti
From my sister:
The second thing that affects me is "I just wish they’d wash their bloody hands." I know exactly what my sister means. It seems utterly absurd. A simple, obvious, easy solution. It's as though Haitians are willing themselves to die. Are they simply stupid brown people? I think a lot of people in the West would answer "yes" to that question. I lot of people I know would answer "yes" to that question. The same people who live their lives drowned in their own absurd beliefs and superstitions. This society functions - its modus operandi - is faith and superstition. Just because our beliefs don't have us dying of easily preventable water-born diseases, doesn't mean that our own absurdity doesn't cripple our existence as obese, angry, faithful, TV watching drones.
It's sad, it's strange, but it's perfectly understandable why someone wouldn't think to wash their hands and go to a witch doctor instead of getting proper treatment.
It's a fucked-up world and all I know is that it doesn't actually have to be like this. The solutions exist already - the solutions to cholera, obesity, faithfulness and irrationality all exist. But finding that path out of madness, that's the only difficult problem left to solve.
One of my neighbours, Abner, caught cholera a few weeks ago. He is the baker and the father of the girls who fetch my water, do my washing and occasionally cook for me.Just one person dead, yet it made me feel a lot more sad than "By late January 2011 some 4,131 people have died and 117,312 are hospitalised." (wikipedia) Of course, I already knew it would, but even as someone who has tried to think/feel in large numbers and concepts, to feel worse about a single case than other 4,130, is really pathetic. Truly pathetic. Even more so because the cholera outbreak is a tiny number of people. As far as deaths go, this has only just surpassed the most over-hyped event of the naughties. (Though, to be fair, millions of people had their lives ruined because of it - 1 & 2) Compared with other events, it's not even worth mentioning (and isn't mentioned). It's an order of magnitude less people than the earthquake in January 2010. Not even worth mentioning.
Anyway he spent a week or so in hospital, was let out, went to someone we would probably call a witch doctor, and then returned home yesterday on a stretcher, no longer able to speak. He died last night, his daughters and wife started wailing at 2am in the morning - the traditional way of expressing grief and letting everyone know that he passed away. Of course, the worse part is that he leaves behind his family of 4 daughters (one of whom has a 4 month old baby) and 2 sons (one 4 years old, the other a teenager). I have no idea how they are going to survive this. I suspect the girls wont be going to school for much longer.
Cholera has returned to my zone, after a brief reprieve... I just wish they’d wash their bloody hands.

The worst thing about Entity Framework
Generally, I like Entity Framework, especially the newest version (part of Visual Studio 2010). The absolute worst thing about it is the error message you can get when you are hooking-up your POCO files to an entity model. The error message is: "Mapping and metadata information could not be found for EntityType [...]"
EF tells you in which class the error is located, but that's it. It could be any of the properties that don't work! If you have a database table with 20 or 50 fields, good luck in tracking down the error. The best info I've found is that the error can be caused by:

- Misspelled properties (case-sensitive!)
- Properties missing in the POCO class
- Type mismatches between the POCO and entity-type (e.g., int instead of long)
- Enums in the POCO (EF doesn't support enums right now as I understand)

Original Dungeons and Dragons
More investigations into role-playing games (mostly to plunder them for ideas) led me to a couple of re-writes of the original Dungeons and Dragons game (the red and blue books! Remember?) The games are Labyrinth Lord and Swords & Wizardry (White Box Rules). And you know what? Original D&D sucks. Badly.
There are horrible tables (attack roll tables?!), saving throws, experience points, ability scores, spell levels, Vancian magic systems, alignments, arbitrary weapon restrictions (as if clerics don't shed blood, come on! The crusades, anyone?), etc.
The idea of moving away from D&D 3rd and 4th edition is a good one. Not moving back to AD&D 1st or 2nd edition is also a good idea. But moving back to original D&D? Not a good idea.
What the authors should have done: Taken the idea of "simple" and applied reasoning to it. Take the nostalgia and remould it into a simple and yet modern RPG. The great thing that original D&D has over 4th edition D&D is evocation. Reading about Charm Person is a lot more evocative than reading about Ray of Enfeeblement. These OD&D games have the evocation but they're extremely tedious, power-gamey and complex.
Who are these RPGs even aimed at? I can't imagine how anyone new to the past-time would be even slightly intrigued by the complexity and weirdness of the books. They're not logical nor do they create a space for players to envision their characters. Therefore, I can only imagine that the new releases are for old-school players. If that's the case, why wouldn't we just grab our old red and blue books from the attic, basement, parents' house, siblings' house, etc.? I know I could, but I'm not going to.

HeroQuest comments
I looked at HeroQuest while looking for a RuneQuest replacement. It's the other Glorantha RPG. It's almost a good replacement. There are few special rules. Keywords, derived from a character's description, are tied to numbers from 1 to 20. Rolling below this number (on a d20) determines success. That is basically it.
The maths, however, like most RPGs, is a fail.
The conclusion is "This is one area where HeroQuest bows more to the demands of the roleplaying form than to precedents set by the source material." Screw that! All we need do is teach roleplayers basic arithmetic and then move on to great achievements, huge rewards, challenging and fun stories. We just don't need grade 3 sums to do that.
And the rest of the HeroQuest? I don't know, I didn't read too much more. I was too enraged and wanted to ride my hobby-horse. However, I think I should return because there are lots of ideas about how to play an RPG, something that is deeply lacking in RPGs these days.
The maths, however, like most RPGs, is a fail.
HeroQuest abilities are scored on a range of 1–20, but are scalable. When you raise a rating of 20 by one point, it increases not to 21, but to 1W. The W signifies a game abstraction called a mastery. You have now reached a new order of excellence in that ability. (HeroQuest 2nd edition, pg 19)To fix this deeply broken idea, the game-master is expected to keep pace (of course):
Supporting characters, with whom you have relationships, improve over time. Values for their ratings are comparative to yours. As you improve, so will they. Narrators needn't track the improvement over time, but simply update their ratings whenever they reappear in the storyline. (pg 61)And to justify it, the author declares:
Why Advance Characters At All?This justification is muddled. Within fantasy, "it is not uncommon to follow a character from humble beginnings to epic achievement." Epic achievement maybe, but that isn't the same as numerical advancement. Not at all. There is little "advancement" in the classic of all fantasy novels, The Lord of the Rings. The characters develop, undeniably, but do they advance in any way reminiscent of RPGs? Gandalf does, perhaps, when he becomes Gandalf the White. Nevertheless, the changes aren't similar to the way one advances in RPGs. The other characters, Boromir, Legolas, Gimli, Strider and the hobbits just don't advance, yet they all achieve great things. Frodo, if anything, regresses. The weight of the ring bares down on him. He barely survives and is certainly no stronger for it.
Few of the adventure genres we draw inspiration from actually feature significant character improvement through the course of a series. Mysteries, pulps, military adventures, westerns, and space operas tend to feature characters who are highly competent from the outset. Occasionally a secondary character, most often a male ingénue, starts out as a greenhorn and proves himself in the course of the story. (Just as often, a once-competent secondary character redeems himself and returns to his legendary past level of competence.) Other, grimmer genres, like horror, satirical SF, and arguably post-apocalyptic survivalism, keep their protagonists relatively weak throughout.
Fantasy is a prominent exception: it is not uncommon to follow a character from humble beginnings to epic achievement.
Rate of improvement is basically, then, a genre element. Narrators who want a rapid growth curve should decrease the costs of ability improvement. Those who want slower growth should increase them.
That said, roleplayers really enjoy increasing their PC’s abilities on a regular basis. Regular ability boosts helps to keep them invested in their characters, and thinking of their futures. This is one area where HeroQuest bows more to the demands of the roleplaying form than to precedents set by the source material.
In series fiction, relationships are another common exception; highly competent heroes often make friends or contacts they meet again in a sequel. Narrators can encourage this with directed improvements. (pg 58)

All we need do is teach roleplayers basic arithmetic and then move on to great achievements, huge rewards, challenging and fun stories. We just don't need grade 3 sums to do that.

FateQuest session report 4
Our fourth role-playing session was different again to the previous sessions. The biggest change was the abandonment of RuneQuest II as the game system. We still have the same adventurers, the same setting (Glorantha) and the same plot (Summons of the Wyter), but a new set of rules. Rules that I've been working out for a while. I'm calling it FateQuest.
FateQuest is basically a hack between RuneQuest and FATE (hence the name). All the good things I liked about RuneQuest (lots of the combat stuff) and the good things I like about FATE (skill pyramid and aspects) have been melded together. The result worked better than what I imagined (and I was imagining something pretty good). I've already tweaked it some more, so it should run even smoother, without a loss of detail.
There is issue, however. It isn't about the game system as such, more about how people play. Half the group of six have never or barely played an RPG before. The other half have either played a lot or at least have preconceived ideas about how to play an RPG (me included). That's tricky. Furthermore, at least one of us wants to play more free-form (few rules, few dice, mostly narrative and role-play). At least two of us like the game/simulation element and the dice, though not all of the time. We all like the debating and figuring out what should happen.
The main thing I tried to do with FateQuest was expunge all of the power-gaming by design aspects of RuneQuest. I think I've achieved that. But it's still a game. Depending on how you look at it, you can still win. It's suppose to be more of a simulation than a game (see GNS Theory) but those two aspects can easily meld together. And people feel good when they win. I don't want them to lose the feeling you get when having a clever idea or solving a problem. In fact, I want to encourage it.
I like frameworks, they can help stimulate ideas and they can give you a game within a game. I'm not sure how we could completely free-form it, though the thought reoccurs. I.e., drop the rules and dice entirely. But who/what would decide? If the adventurer's life is in the balance, I don't want the game-master to decide the outcome. That's too much responsibility. That's why game-masters hide behind a probability wall - they can always blame the dice. And yet, adventurers' lives should hang in the balance. Perhaps all the players (GM included) can simply agree that the adventurer got into too much trouble to be able to survive, or at least, remain conscious. I dunno.
The other potential problem with free-forming it is that events will probably move a lot faster. We'd definitely be moving out of the Glorantha setting in no time. We'll also move out of an ancients setting too (i.e., Greek/Roman). Mostly because we don't know all that much about Glorantha (I know at least ten times more than the other players, but very little overall) and I don't think any of us know very much about an ancient way of life, though more than a regular schmuck. Neither of those things are necessarily bad, but I'm enthralled by Glorantha and imagining other ways of life is what role-playing is all about.
Trying to speed through the combat section - because I didn't want anyone to get bored - without actually allowing players to collectively decide what they were doing wasn't a great move. However, because we had a new set of rules, needing explanation at the same time as being played, it was quite difficult to fit everything in.

Events:
The horsemen approached Verstead. Hengall hastily organised a shield wall at the broken gates (the only feasible entrance to the stead, at least on horseback). As the horsemen closed in, it became apparent that they were clan-members from the Orldor family. They were Old Ways Traditionalists, perhaps, but not enemies. The shield wall came down.
As the horsemen rode into camp it became apparent rather quickly that something was amiss. Some of the Orldor carls looked nervous. Iddi Iddrosson, the Orldor leader, almost looked pleased.
Soon enough, Iddi declared that he'd like to move into Verstead now that the Jendarls wouldn't be needing it any more. Hengall and the adventurers attacked. Of course, the adventurers went straight for Iddi. Most blows were ineffectual, but Flavias managed to strike Iddi's head with an arrow, though his helmet protected him from any serious injury.
Anid, Trax and Soliste were heavily involved in fighting the carls and weaponthanes. Flavis, with her bow, attempted to stay further away. Ben Poleo slipped away to try to free Arlyn. Ben also shouted out to the assailants that their attack was without honour, further demoralising the carls.
Anid and Trax are competent warriors and they could hold their own against the carls and thanes. Soliste, on the other hand, struggled. By the time Hengall ordered them to leave to save the wyter at the Black Grove, Soliste had already suffered injuries. A short-spear became impaled in her left arm. With the help of Anid, she was able to retreat from the battle.
The party gathered their horses once they were out of the fight. All six (including Arlyn) mounted their three remaining horses - there was no time to acquire new horses. As Soliste mounted her horse she was forced to withdraw the impaled short-spear. The pain was overwhelming and she fell unconscious.
The group rode towards the bared exit. With Arlyn's help, the group managed to easily flee Verstead.
We left them as they were on their way to the Black Grove.
