Actually I was looking for a function that would take out elements from one list mentioned in a second one, but not more than the ones named in the second. I hoped that Complement would have an option to do that
Also I have been staring like hours at Flatten's fourth syntax variant. I'm getting old. I do not seem to be able to make a mental image of what it does.
One thing I could never wrap my head around is how Flatten works when provided with a matrix as the second argument, and the Mathematica help isn't particularly good on this one.
Taken from the Flatten help page in Mathematica 8:
Flatten[list, {{s11, s12, ...}, {s21, s22, ...}, ...}]
"Flatten...
@David: when I try to used the command that was posted earlier to ImageMultiply yoda's avatar, the green rectangle is never big enough. It is as if there were some unwanted clipping going on.
I am not sure if software-engineering (taste) questions should also be asked . E.g., is anybody using git in WWB ? I only got it to install when using the WWB-eclipse-plugin (i.e. with eclipse 3.7.1). Or, another one: Is it easier to explain CVS, svn or git to an engineer or phycisist using Mathematica?
it is especially amusing to speak dutch to germans (because you don't actually speak german and they don't speak english). especially seeing their expressions
@yoda: when I try to use the command that was posted earlier to ImageMultiply your avatar, the green rectangle is never big enough. It is as if there were some unwanted clipping going on.
BTW: we could ask ruebenko (Oliver Ruebenkoenig) as moderator. Not sure he will do it, but last time I talked to him he had no kids. AND: He is really very very good (o.k., he works for WRI, but that can only be good I think).
But your gravatar has stuff that is past the edges of what appears when I execute the command: `Binarize[Import[ "http://www.gravatar.com/avatar/64eb54939201cd78d919a3959aeb417d?s=\ 512"], .3]~ImageMultiply~ Graphics[{RGBColor[0, 2/3, 0], Rectangle[{0, 0}, {512, 512}]}]`
I could use another program to do the colorization, but that is cheating :-)
and the white edges are surely some padding applied by Graphics
ok.. so I figured out. The white area corresponds to the frame applied by Graphics. Although it is absent, the space it would've occupied is left white. You can see it by setting Frame->True
When I want to search for posts of a specific user, the search faq says "user:12324". Where do I got the user-number, because user:"Leonid Shifrin" does not work..
alternately, if you go to their profile, the search field is already auto filled with user:x.. so if you want to search for anything by that user, just need to type the search terms
It's funny, I'd just run the notebook before logging on
I think the second one is quite interesting. Declines in the right-hand panel during the private beta as people followed to be informed when the public beta started, and picking up now. Also some committers only registered with the site once the public beta started.
@Szabolcs as mentioned - there were people still following for the first tim during the private beta, so that they'd be informed when the public beta started. The denominator rose from about 90 to 111 during that time.
there are a couple of users who are very close to avid user status.
I will be offline for much of this weekend - urgent family visit
In the meantime
Our good performance on follower conversion is partly an artefact of our speed to beta - and partly because most followers committed. This hasn't been true for many other betas.
As you said, if we are going to promote the site, we might need a preliminary logo.
I didn't post about this yet (I thought it was too soon---we just got out of private beta!), but my idea for a site logo was using a spikey:
We can have a spikey-design contest to create a special logo for thi...
@Sjoerd I specifically talked about that --- if should not be identical to any existing logo. It should just be recognizable, i.e. based on a dodecahedron or an icosahedron. They can't trademark a hyperbolic dodecahedron in general, they can only trademark a single finished image.
perhaps you can TM a hyperbolic dodecahedron in the context of a product?
I know a company who has trademarked a color in connection to its domain. No other network operator may use this particular tint of color in its house style
If like the idea and make spikies, then if it looks like a copy, I agree, it's boring. It should be creative and as different as possible, while having some recognizable element too. I thin the one on verbeia.com reminds of Mathematica, even though it's not even a dodecahedron or icosahedron
We've talked about here and there pieces of this, but what should go in our FAQ? What do you think needs to mentioned in our FAQ? Obviously, what is considered on-topic/off-topic, and quite possibly a number of items from this list. But, we should start making progress on this question.
(This is...
As we have entered public beta, it will soon become apparent that we need more moderator attention than can be given by the SE mods that have accounts here. We already have two users who have access to the moderator tools, and possibly one or two more soon, which helps quite a bit. But, we will ...
I have a number of questions now, but they are not really good ones
Right now I'd like to know if it's possible to have LinkRead have a timeout
I think it is, I'd need to dig into sakra's Remote Kernel Strategies package, as I seem to recall seeing something like that there ... but too lazy now :)
Good questions take time, one needs time to try to come up with solutions first
I can reproduce the problem, which means it's not specific to his machine, but it's either an Ubuntu problem or a general Linux problem
tbh I gave up on Mma on Ubuntu, every new version of Ubuntu breaks something until it becomes almost unusable
I have no sound, serious graphics problems from crashing to images disappearing or menus not showing, conflicts with the window manager, and text input simply not working at times. also, everything gui related is bloody slow. since some people use it on ubuntu, probably it's not nearly as bad for most
