Happy UTC new year all
 
@bobthechemist I officially confirm, you were the first.
 
12:48 AM
@halirutan Must mean I wasn't invited to the "cool" party...

Happy new year! I'm on a drifting sleeping schedule so I missed the UTC one but caught some of the New York one.
 
5:11 AM
Idem to everyone

Happy new year!
 
6:50 AM
@bobthechemist I was home with the kids too. So don't worry. Honestly, I slept until 0:05 when all the noise started because I fell asleep while reading book with my daughter.
Here is a nice one:
The comments are hilarious:
"Time for Oedipal Edition. Charge extra."

@halirutan That actually sounds like a great way to spend this holiday.
 
@bobthechemist You mean having children with your daughter?
 
@Zibadawa No the book-reading with one's daughter :D (Since the chat is archived, I guess I should have made that Very clear.)
 
1:53 PM
Late HNY!

Hi dear friends. Happy new year. Would you please check the answer presented in this post: mathematica.stackexchange.com/q/39488/7115
It does not work on my computer. I think something is wrong with my computer.
 
4:57 PM
@M6299 I get the solution in about the same time
 
@rm-rf Thank you. What version of Mathematica do you use?
 
5:10 PM
@M6299 Sorry, I can reproduce your problem in 9.0.1... it doesn't finish computing (I killed it after 15 mins)
 
Dear @rm-rf What version of Mathematica did you used first?
 
5:25 PM
@M6299 I have a better way...will update in a little.
 
Tried it also killed after 20mins M9 and W7.
 
Another shameless plug: I built a spectrophotometer with Legos and a Raspberry Pi, and control it using Mathematica

5:46 PM
@LiamWilliam @MichaelE2 Thank you.
 
6:30 PM
@M6299 Michael and I both accidentally used a beta version of Mathematica 10. It works in that, but not in 9.
 
@rm-rf When will Mathematica v10 be released?
@rm-rf Where can I download Mathematica v10 beta?
 
6:47 PM
@bobthechemist That's so cool. I'm telling my friends!
 
@bobthechemist really great! I'm actually a bit surprised that it works without a slit and with a CD piece as the grating
 
7:10 PM
@OleksandrR. Since the photoresistor is already small (about 2 mm) and the resolution on my stepper motor is so poor, a slit wouldn't do much. The CD grating works better than I expected. In a dark room you can see that part of the blue region is missing, but otherwise it is a fairly continuous spectrum. The hard part is orienting it since the grooves are radial rather than linear.

@rm-rf I re-edited the title of (24857)--$MachineEpsilo‌​n is actually irrelevant to this scenario
Well, sorry about those two characters. Apparently someone used PHP somewhere. What a mistake to make!
 
10:04 PM
@rm-rf haha I see. Well, maybe the question would not be useful if it were only representative of its title, but I think the topic of how useful is Mathematica for writing general applications is an important one. I guess 16 other people agreed
 
10:19 PM
happy new year everyone

My brain is at a stand still for the moment. I'm working with what is supposed to be a tree data structure. I implement it as nested lists: {item, { {item, {...}}, {item, {...}} } } the problem is how do I apply a function to each node? I'm going to write the function such that the leaves have to evaluated first, so that the tree can only be evaluated from the bottom up. In the end each node will have been replaced with a new value.
 
@Calle ReplaceRepeated?
Oh wait. Might be more sensible to use FixedPoint and Replace actually
@Calle rather a similar kind of operation: mathematica.stackexchange.com/questions/20180/…
