Well.
I was checking my "spam filter" email address, which I've had since 1998...and I discovered that Facebook had sent me some "password
verification/change" notices.
This is odd because I've never signed up for Facebook.
Needless to say, I went to the site and took the effort to scrape the account and change my passwords... again. *sigh*
Any other security tricks I should undertake so these skript kiddies don't sign me up for credit cards?

| Technobable on Speed Drives - comment/discuss? |

In trying to come up with new stuff for the new wiki, I tried to formalise my thought son how speed drives could work (given the known limitations). I didn't get much.
What I do have is below, so have at it.
Speed Drives
Speed drives are Wavetech systems working essentially by the principle "Constant Thrust equals Constant Speed". At its most basic, a Speed Drive envelopes the object to be moved in a pseudo-gravetic field and warps space to travel.
How it works
The pseudo-gravetic field used to envelop the object serves two purposes. First, it acts as an inertial dampening field. Second, it acts as an isolating barrier to the space-time warping that actually moves the object, and to general space-time.
The drive, once the object is isolated, then induces what is termed a ‘Gravity Gradient' at the interface between the field and real space. The gravity gradient acts much like a hill for the object to ‘fall down', much like a surfer ‘falls down' the front of a wave.
Limitations
The Speed Drive, as currently known, has two limitations; both of these have to do with how it interacts with the universe.
The first limitation on Speed Drives is the nature of the pseudo-gravetic field. The field does not totally isolate the object being moved from space-time. This is necessary to allow navigation. Because of this, the field encounters the phenomenon known as Frame Drag (more correctly wavefront induced frame dragging). This is the distortion of space-time caused by the movement of large masses. As the field simulates this, the interaction at the interface with normal space-time causes interference in the space warp effect. This reduces the gravity gradient and at a certain point, the field collapses due to destructive feedback.
This is the cause of the speed limits on the drives, as interactions between the distortion caused by gravity wells (like planets and the Sun) and the field disrupt the creation of the gravity gradient, reducing the speed of the space warp front.
The second limitation is the creation of the gravity gradient. As this relies on the pseudo-gravetic field, the actual generation of the field is important. This is limited by a combination of three factors: the mass being enveloped, the size of the field, and the power of the drive generating it.
The mass being enveloped is the fundamental limiting factor. The sharpness of the gravity gradient is reliant on the difference between the mass being simulated and the actual mass. The smaller it is, the less the maximum gradient can be. All else being equal, a cubic metre of iron can be propelled faster than a cubic metre of copper.
The size of the field also limits the gradient, as larger fields mean larger surface areas for the interface. This reduces power at the interface.
Finally, the power of the drive limits how strong the field can be.
Thus, the larger the object, the greater the mass and the size of the field needed to move it. However, the larger the object, the larger and more powerful the drive it can mount (which of course increases the mass).

I was just reading the article in the Fenwiki on Kaboomite when I noticed that it claims that
the Stellvians gathered all the 'easily accessible' fissionables. That got a raised eyebrow from me. The other eyebrow went up at the mention that
they only had three warheads (though I'm pretty sure they went through their share of test warheads).
BTW: Nice stroke of genius in having the Bubbleheads fire those shots - most Fen would figure that the Navy would naturally bring nukes to the table anyways.
Now, I'm not disputing either of those claims, but it does make me wonder what constitutes 'easily accessible' in this case, becaus there honestly
has to be a lot more fissionable materials out there than only enough to make three warheads.
Reason I'm wondering is because Fenspace!Ben is interested in wave-enhanced nuclear energy. Sure, people are tinkering with some interesting stuff, but
that doesn't mean he won't do any tinkering himself and basing it off of something that's tried and true 'Dane tech.
(Although, whereas nuclear power is concerned, I understand that some people feel that a grand total of two catastrophic accidents constitutes the abandonment
of progress. Wonder how many catastrophic wildfires got started by cavemen?)

http://www.sankakucomplex.com/2010/01/14/lin-i-chen/]This weekend's "fine art" gallery at Sankaku Complex (warning: it's at Sankaku Complex) actually is fine art - it's a collection of pieces by a Taiwanese artist named Lin I-Chen (who also goes by the name "Eat" for some reason). Many of them bring various game scenarios to mind... or, at least, they do for me. But I don't have time to write up 42 different plot or character seeds, and I don't game in some of the genres shown.
So I thought I'd open this up to everyone to take part. Pick an image and tell us how it can be used in a game.
The files are named in the format "lin-i-chen-eat-###.jpg", with ### replaced by a number from 001 to 042. Let's refer to them as "Image ###" with ### replaced by the appropriate number. For example:
- Image 13 is obviously set in a supernatural wuxia setting. The young lady is the sister of a swordsman who you defeated last game session; in her grief and anger, she has made a pact with the undead in order to take revenge upon her brother's killers. Can you defeat her and her spectral minions? A heel-face turn on her part isn't possible, because of her pact - you'll have to defeat her in combat... or some other way.
- Image 13 (again) is obviously set in a fantasy setting. The young lady is a summoner/fighter, using her skills to defend her homeland against an even worse threat. But there's a battle coming that she knows she isn't powerful enough to win on her own, so this mysterious stranger has come to a tavern...
- Image 13 (yet again) is obviously set in a fantasy setting (again). This swordswoman has been cursed; can you help her retrieve the rare item needed to break the curse? Time for an old-fashioned dungeon delve!
- Image 37 is a picture of your Illuminati University character's NPC love-interest. What is that... whatever-that-is under her arm, that she's brought to Esoteric Engineering class today?
Any more? (I expect to see either Shadowrun or Technomancer referenced for Image 21, and Image 36 is "obviously" a D&D ranger of some sort... but I could be wrong on both counts.)

The light stopped pulsing and suddenly coalesced to form a
holographic image of Usagi in "princess mode", complete with all
the accessories she'd acquired in the last moments of the battle
against Beryl -- the golden breastplate over her gown; the crown
with six points, one each of earth, water, fire, ice, lightning
and light; and God's Toothpick (!) with the crescent moon wand
mated to one end to turn the whole thing into something like a
bishop's crozier, with the Ginzuisho blazing like white fire at
its center. Her eyes were closed, and there was an expression of
(forgive me) serenity on her relaxed face.
"Ohmygod!" Dawn screeched. "That's... That's Serena!"
"Usagi," I corrected absently. "Her name is Tsukino Usagi."
"But..." Dawn began, and at that moment the image's eyes snapped
open. It looked straight ahead, as if into some unseen camera,
and did not seem to acknowledge either of us.
"Hello, Doug-Sensei," the image of Usagi said in faintly-
accented English, and I smiled fondly at the sound of it. (Need
I note that she sounded nothing like the actress in the cartoon?)
Usagi could speak English perfectly without an accent -- like
Dee, she'd acquired complete fluency from a magical accident --
but she loved the idea of sounding "exotic" to native speakers,
even ones who knew better (like yours truly). It was one of her
few concessions to a minor streak of vanity she normally kept
well suppressed. "I'm not entirely sure this will work, but if
it does, yay me." She grinned without quite looking at me, and I
suddenly felt a pang of loss. Usagi and the other Sailor Senshi
-- Makoto especially -- had been like daughters to me. And I had
seen all of them but Usagi fall to Beryl's forces before I'd
suicided to take out the dark queen's fortress.
*Before I'd *suicided*...*
A surge of hope washed away the loss as I realized something that
should have been painfully obvious to me years earlier.
"I wanted to let you know that in the end, I beat Beryl, and with
the leftover power given to me by everyone I told the Ginzuisho
to bring you all back, which it's done. It's also going to set
things up so that you can move on. But before that, I wanted
to..." Her eyes grew shiny. "I wanted to tell you that we're
all okay, even after everything that happened, and that we love
you, and that we'll miss you. And please come back to us some
day, if you can."
"Oh, Usagi-aijou..." I murmured.
"Wow," Dawn breathed. "What did you do?"
"I taught them," I said softly. "And advised them. And died for
them."
Dawn looked at me with wide eyes. "You went to the Negaverse
with them!"
"Dark Kingdom. Yeah," I said, studying the holograph, which
seemed to have paused itself while we spoke. "I used my metagift
to basically detonate a nuke in the heart of Beryl's palace."
"Whoa," she breathed. "That's nothing like how the cartoon
ended."
I shrugged. "I wouldn't know about a cartoon. I just know about
real life."
Dawn turned from me and was studying the quiescent image. "And
what she's wearing is different, too. I mean, she had the dress
in the cartoon, too, but not the armor stuff. And the crown...
wow. That's just amazing."
"You really think so?" The image suddenly turned to look
directly at Dawn, who shrieked and jumped back.
"It talked to me!"
The image of Usagi blinked, and looked Dawn up and down. "Oh,
I'm sorry, I thought you were Rei for a moment."
"That's been going around," I muttered under my breath.
Trembling, Dawn raised her arm and pointed a finger at the image.
"I thought *you* were a *recording*!"
Usagi gave an embarrassed smile and rubbed the back of her head
with her right hand. "Um. Well, I *am*. Kinda." She emitted a
very familiar nervous chuckle.
"Usagi," I said, dropping back into my "sensei voice" with her
for the first time in decades, "what did you *do*?"
Her smile shifted from embarrassed to sheepish and her affected
accent disappeared. "I guess I sorta kinda put too much of
myself in the message? And I forgot to put a terminal condition
on the enchantment."
"So I've been carrying a soulprint of you in my head for all
these years? Why the hell haven't you played before now?"
"Um." She looked over at Dawn, who was still staring with wide
eyes, and then back at me. "I think I flubbed the activation
conditions, too." I rolled my eyes, but when I opened my mouth
to comment, she scowled at me. Which on her just looked
adorable. "Give me a break, Sensei! I'd just had everyone die
on me, even the ones who were dead to start with, I'd just beaten
Beryl, I'd resurrected *everyone* the Kingdom had killed, *and*
I'd rewound the whole planet a year to give us all a 'do-over'.
*Plus* I set myself up as the guardian to watch over everything
in case some other threat popped up. *And* I made sure you got a
portal that would carry you toward your home world! You're not
going to get on my case for messing up a... a... a phone message,
are you?" Her lower lip began to quiver, and as her eyes began
to swim with tears, all the confidence of Serenity II vanished
from her; light rippled across her form, and then she was back in
her school uniform. She looked more like the schoolgirl I'd
first met one busy night than the Queen she had become.
