Is there a name for the steering style/wheel actuation used on Curiosity?

I read up on the wheels of Curiosity, and also about the suspension. But is there a name for the steering? It looks similar in nature to the front landing gear on an airplane, but searching those terms didn’t turn up and answer. I’ve attached a picture with the area of interest highlighted.

Music using orchestra with a singer and a pop/rock/jazz song’s style?

I wonder if there is a special name for the kind of music as there are an ochestra and a singer singing a pop song, a rock on or a jazz one. I’ve listened to some of them (but hardly with a pop or rock influence) such as this one that I found : (this song is maybe not the best example of what I’m looking for though).

So I wonder if you knew any genre looking alike or any artist doing that kind of music?

Vancouver style file accuses me of popping an empty literal stack

This document (problem.tex) and bibliography (problem.bib) work as expected:


  title={Districting principles and democratic representation},
  author={Altman, Micah},
  school={California Institute of Technology}

However, changing “plain” to “vancouver” causes this error:

You can’t pop an empty literal stack for entry altman

while executing—line 1865 of file vancouver.bst

I checked in Wikipedia and the @phdthesis entry seems to have the right attributes. What is happening with the vancouver.bst and what should I do about it?

Is starting from sides a bad style?

I am just an average chess player around 1500+ ELO
and have started experimenting to come up with a complete new style of my own. (it may have been used or discredited in the community)

This involves starting from corner pawns on each sides rather than the middle.

Here is an example game:-

[FEN ""]

1. h4 e5 2. h5 d5 3. a4 Nc6 4. e3 d4
5. g4 dxe3 6. fxe3 h6 7. Nc3 Nf6 8. Bg2 Bxg4
9. Bf3 Bxf3 10. Qxf3 Qd6 11. Nb5 Qd7 12. c3 a6
13. Na3 Bxa3 14. bxa3 O-O 15. d4 exd4 16. cxd4 Rae8
17. Ne2

What do you have say about this? What kind of chess player am I?

Attributing TV media sources in online, AP style, journalistic articles

I am the editor of a small news blog. I am trying to train my writers to link to their sources.

One writer sends me an article without linked sources, so I ask for the sources. They email back responding that the way they obtained their sources was that they simply saw some information on television. The information in their article was detailed with a lot of data. They would have needed to be paying very close attention to some in-depth coverage if this were true.

I emailed back and told them to find an online version of the source since news outlets often put their material online.

I’m not sure if that was the best advice or if there is something better I could advise them to do.

If you know the best way to give proper attribution to sources in this situation please let me know. I do not want to do it wrong or teach it the wrong way.


Stock options: payoff diagrams assume European style exercising

Most literature on stock option strategies expresses payoff outcomes in terms of European options — namely, ones that can only be exercised on the expiration date.

See this Iron Condor payoff diagram for example (with long put @ 35, short put @ 40, short call @ 50, and long call @ 55):

Iron Condor Payoff Diagram

Most options brokerages in the US have American-style options that can be exercised at any point before or during the expiration date. This means that for multi-leg option strategies, you could afford to lose more than these diagrams traditionally show.

In the above example, you could lose more than projected if the stock price reaches $35 and $55 at separate points before the expiration date, given that you haven’t closed your open contracts when the stock hits either of the two prices. How do people usually handle this?

Achieve Damascus steel style with Cycles

so I’m modeling a katana, and I would like to give it a proper “Damascus” style to the blade, and I was wondering if it’s possible to achieve this in a way that doesn’t involve me opening GIMP/Photoshop.

The desired effect is this:
Damascus style knife

So far I got this material:

Ignore the red tint.

So my questions are:

  1. How to “mask out” the black so I can control it, and apply the Principaled on top of let’s say a brushed metal shader.

  2. Is there a way I can make the noise/musgrave/voronoi start in stripes and then go wavy? Maybe aWave texture and use a ramp to fade them?

Thanks for any input!
