Dear Cfsbf, 

Truth

White people need to tell each other the hard truths. This includes the fact that No, you aren’t colorblind. Nor should you strive to be. The point isn’t whether or not you see that a person is black. They are. The question is what you see when you see that they are black. Do you see competency? Do you see worth? You should.

(paraphrased (because I didn’t write it down during the service) from the sermon at the First Presbyterian Church of Atlanta on 25 September 2016)

Hello tumblr Cosmere fandom!

This last weekend was the MIT mystery hunt and this got me thinking.  Branderson's world building has given us all sorts of lovely systems that could be used as the basis for puzzle-hunt style puzzles.  Are there other puzzle hunt type people around the tumblr cosmere fandom?  If I were to actually turn one/some of the puzzle ideas floating around my head into reality, would there be people interested in poking at it/them?

Yahoo Groups Will Be Shutting Down - What Each of You Can Do

This post will be frequently updated - check the Google Doc linked here for the latest version. Follow this Tumblr for more information in the days ahead.

Yahoo Groups will be shutting down key features and restricting access to Groups, with user-uploaded content being deleted on December 14, 2019. With this shutdown, decades of fandom history will vanish. But there is something that every member of the fandom community can do now - whether they’ve ever used Yahoo Groups before or not.

I am a member of a Yahoo group - what can I do?

Immediately contact the admins to find out what their plans are.

Download PGOffline, a Windows tool to save the files and messages. Any member of the Yahoo Group can use this tool - you do not have to be an admin to save the mailing list. 

Since many admins are busy or inactive, install the free Windows software program yourself and start downloading - focus on Files, Photos, Links, and Messages. A step-by-step walk through is available here and a video tutorial here.

Submit your plan to download here.

 Export the messages and backup up the files and photos by copying them to another folder on your computer. Then contact Open Doors, the OTW preservation program. The OTW is open to providing storage of Yahoo Groups backups that are assembled by moderators and non-moderators alike. Details are here.

If you are a member of a Yahoo Group and have downloaded the files and messages, and the admins do not respond, please contact your fellow mailing list members. Remember, anyone can save a mailing list messages, files and photos and submit them to Open Doors.

Click here for instructions on how to use the Chrome plugin

If you need help from fellow fans, try asking on the “Save Yahoo Groups” Discord Channel

Mac Users: try this Chrome based plugin

Instructions on how to use the Chrome plugin

Alternatively, if you are familiar with Python, please experiment with the tools found at https://www.archiveteam.org/index.php?title=Yahoo!_Groups

I am Admin - what can I do?

Communicate with your Group members - let them know your plans

Download your Group messages, files, photos, and links using the tools above. Don’t forget to download your members list.

Decide if you want to simply archive the old posts and disband the mailing list or start up somewhere else.

Please take a look at setting up a Dreamwidth community - it allows explicit material, threaded conversations, privacy locks and is free. Image uploading is limited to 500MB for free accounts and 1.5GB paid accounts. Also, if you are considering Groups.io as an option, please note that it does not allow any material that depicts sexual activity, even implied sexual activity or anything that could be considered a fetish.

I am not certain I have time to help download? Is there something else I can do?

If you are a member of a mailing list, submit the mailing list for consideration. It will help volunteers focus their efforts. Don’t forget check here to see if your group is already being downloaded.

Even if you are not a mailing list member, consider creating a page for the mailing list on Fanlore, so that there will be a place for people to talk about the mailing list, its history. Details here.

Login Problems?

Has your “inactive” email been purged? Is your email email address not linked to a Yahoo Group ID?

An “inactive” account is one where you haven’t sent an email or logged in for the past year. Receiving emails does not count as activity. The email address is then released, and can be used by someone else.

If you used your Yahoo email to subscribe to a mailing list, your access to the Yahoo Group is gone (along with all your emails). If your account was deactivated within the past 90 days, you may be able to reactivate it. (more here). Alternatively, you can try contacting Yahoo Mail support.

Outside the 90 day window: you can try creating a new Yahoo email account using the same screen name as long as no one else has snapped it up. Simply sign up as you would for a ‘new’ email account. Reclaim an inactive mailbox. Then log into your Yahoo Group.

Rithmatics: Part 5 - Curvature, Ellipses and a Guess at the Blad Defense

Let's start by considering a snippit from one of the diagrams in The Rithmatist:

(Note: full diagram can be found at http://brandonsanderson.com/books/the-rithmatist/the-rithmatist/rithmatist-maps-and-illustrations/ )

Now we have a problem, namely, circles don't all have the same curvature. In fact (a slight simplification of) the idea of calculating curvature is to determine what radius circle would best approximate the curvature of the line at that point. A circle of radius r has constant curvature 1/r.

The basic idea here is reasonable though – apparently, lines of warding are stronger when they have a higher curvature. You can think of an ellipse as a circle that has been stretched along one axis. This means that if you start with a circle and then stretch it, we can talk about the resulting ellipse being stronger than the original circle where it curves more and weaker where it curves less. Here is what that diagram might look like if we add in the relevant reference circle:

Assuming this interpretation is correct, there are some important implications. The biggest is probably that the size of the circle used to form a defense matters. If you have two otherwise completely equivalent defenses and one of them is a scaled up version of the other, every point in the wall of the smaller defense will be stronger than the equivalent point in the wall of the larger.

Note: There are at least two potential underlying explanations for what is going on here. One option is that there is a certain strength inherent in a portion of a curve of a given curvature. This is the assumption that I am going to work from here. There is also the possibility that there is a fixed total strength for any closed curve of warding and that this strength distributes itself based on curvature. If we stick to circles and assume that strength and curvature are proportional, the two notions are equivalent. The second option is intriguing, but leads to rather messy calculations when we start looking at more interesting constructions. If I stick with this long enough we may eventually get there. I have no idea which option is correct or whether there is a third one I haven't considered.

One way to think about this (and this is almost certainly an oversimplification of things) is that it might take approximately the same amount of chalkling effort to destroy the entire dark blue segment as to destroy the entire dark green segment in the figure below:

 The important take away is that it should be easier to break a small hole in a large circle than it is to break an equally sized hole in a smaller circle. This means that when you are drawing your initial circle for your defense, you should be actively thinking about how large you really need it to be. It also means that even the weakest point on an ellipse could still be stronger than the wall of a much larger circle.

From an offensive standpoint, this means that the small circles and Mark's crosses added to your opponent's main circle are going to be much harder to affect than their main line of warding. They aren't just in the way – they are actually stronger.

We will talk about ellipses in more depth in future installments, but for now let's close with a guess at what the Blad Defense might look like. All we know about it is that it combines four ellipsoid segments in a non-traditional manner and that it is strong enough that some people think it should be banned from competitions.   

I live near Atlanta and Labor day weekend is approaching, aka that time of year that Atlanta turns into nerd central - we get both Dragon Con and the Decatur Book Festival on the same weekend.

I love the idea of Dragon Con. I love seeing all of the amazing costumes people make for it. But as a person who is easily overwhelmed by large crowds and who has a distinct preference for books over tv and movies, the Decatur Book Festival is much, much more my speed.  Sadly, there is a distinct lack of anything fantasty/scifi on the book festival talk schedule this year. And Sanderson is going to be at Dragon Con... It makes it tempting to consider...

Realistically though, I’m going to be happier at the book festival. 

If anyone else is going to be hanging out in Decatur that weekend looking at books and wants to meet up for ice cream (there are a couple of great ice cream shops in Decatur) or tea or something and chat about the Cosmere, or Imperial Radch, or Wayfarers or... let me know :-)

Hey Cosmere fandom, it’s book rec time.

The book series in question is the Imperial Radch Trilogy by Ann Leckie. In order, the books are Ancillary Justice, Ancillary Sword, and Ancillary Mercy.

It’s a space opera with significant focus on character and relationships. The POV character is Breq, an aro-ace space warship AI in a human body who sets out on an impossible journey to kill the Lord of the Radch (the local 3000 year old space emperor) to revenge her beloved Lieutenant. Along the way she (unintentionally and reluctantly) collects people (humans, ships, aliens,...) in a gloriously messy found family.

* It’s super queer 

* Characters actively struggle with depression, anxiety, addiction, etc.

* Almost everyone is a PoC

* For the sake of Propriety everyone wears gloves and bare hands are super scandalous. 

These books are amazing and you should strongly consider reading them. The audio book versions are also fabulous.

If you’ve already read them, I’ve been Radch posting on my other blog (RithmatistKalyna) and I would love to talk with people both about the books/characters/tea sets/etc and all of the Cosmere crossover potential.

If you have questions about editing or the Coppermind in general, I would also be happy to help/encourage you :-) 

In the vein of wikipedia’s wikiprojects, I have recently made a few pages which will help people who are looking for a way to contribute to the coppermind but don’t know where to look to find things that need doing. They are a set of pages which list the status of various articles, so you can see which articles really need help. As a new contributor, adding content to the articles in the good or stub categories of your favorite series would be a reasonable place to start.

Oathbringer Speculation: Timbre

The descriptions of Timbre would fit with the name “lightspren”. We know that she communicates with Venli by pulsing to different rhythms. During the first shadesmar boat trip, Shallan speculates that the Reachers/lightspresn are using vibrations (ie pulses) to communicate.

This suggests that Timbre is a Reacher, but I suspect that she’s not just any Reacher. We meet Ico in Shadesmar and learn that his father is a deadeye and his daughter “ran off chasing stupid dreams”. Then Timbre tells Venli that her own grandfather was lost to human betrayal. Putting all of this together, I strongly suspect that Timbre is Ico’s daughter. I’m not sure what implications this will have for the future. But it’s a thing.

Citations: (Note: Page numbers come from the Kindle edition.)

What was that small spren that had crept out from beneath Eshonai’s corpse? It looked like a small ball of white fire; it gave off little rings of light and trailed a streak behind it. Like a comet. (pg 340) 

“The copper vibrates,” Shallan said. “And they keep touching it. I think they might be using it to communicate somehow.” (pg 931)

 “Wait!” Adolin said. “Ico, I saw something moving back there.” Ico locked the door and hung the keys on his belt. “My father.” “Your father?” Adolin said. “You keep your father locked up?” “Can’t stand the thought of him wandering around somewhere,” Ico said, eyes forward. (Pg 946)

Ico speaking:  “My daughter used to work there, before she ran off chasing stupid dreams.”  (Pg 948)

Timbre pulsed to Irritation, then the Lost. “That many? I had no idea the human betrayal had cost so many of your people’s lives. And your own grandfather?” (pg 1196)

(Probably Crazy) Nightblood Theory

So, I just had a probably crazy idea.  

What if Nightblood isn't actually completely native to Nalthis? What if Nale is bringing it back home when he gives it to Szeth? Nightblood could have been a Rosharian Shardblade (Szeth doesn't seem to question it being a shardblade) that ended up on Nalthis. Then when Vashar and Shashara awakened it, the process roused the dead/trapped spren in the shardblade.  From what we have seen,  spren require an active bond with a human to remain sentient in the physical realm.  Awakening would interact strangely with this resulting in the spren needing a steady supply of breath to remain active.  This could provide an explanation for why it sucks the breath out of people (something that is never really explained in Warbreaker). 

Nightblood's inability to fully understand what evil is and place it in a human context runs reasonably parallel to Pattern and Syl's attempts to understand the more abstract concepts of the human world.  In Nightblood's case, the spren is still trapped in the sword and since it doesn't have a proper bond with a person, it is even harder for it to learn, so it can't progress as well or as quickly as Pattern and Syl.

The more I think about this the better it is working...

Ok, so after the skyeel came out yesterday, I decided to try a chull today.  I'm not entirely happy with it, but here, have it anyway.
